A 21-year-old female patient recently diagnosed with severe hypothyroidism was found to have a large ovarian cyst. In view of the large ovarian cyst, she was advised to undergo elective laparotomy in the gynaecology department. She was further evaluated in our medical out-patient department (OPD), and elective surgery was withheld. She was started on thyroxine replacement therapy, and within a period of 4 months, the size of the cyst regressed significantly, thereby improving the condition of the patient significantly. This case report highlights the rare and often missed association between hypothyroidism and ovarian cysts. Although very rare, profound hypothyroidism that can cause ovarian cysts in an adult should always be kept in the differential diagnosis to avoid unnecessary ovarian surgery. Hypothyroidism should be considered in the differential diagnosis of adult females presenting with multicystic ovarian tumours.Adequate thyroid hormone replacement therapy can prevent these patients from undergoing unnecessary and catastrophic ovarian resection.Surgical excision should be considered only when adequate thyroid replacement therapy fails to resolve ovarian enlargement.In younger women with ovarian cysts, it is also desirable to avoid unnecessary surgery so as to not compromise fertility in the future.

Ultrasonography (US) is the diagnostic modality of choice during work-up for ovarian torsion, although computed tomography (CT) may be used. We examined the utilization of CT in girls with ovarian torsion, and determined which patients are most likely to undergo this study. The Nationwide Emergency Department Sample dataset was searched for patients <18 years who presented with ovarian torsion from 2006 to 2012. Hospitals were categorized by the volume of pediatric patients seen. A total of 1279 patients were identified. Seven hundred twelve (56%) were seen at adult hospitals, 154 (12%) at pediatric privileged, and 413 (32%) at pediatric hospitals. Patients cared for in a pediatric or pediatric privileged hospital had more US alone performed to diagnose ovarian torsion (p < 0.01). Girls seen at pediatric hospitals are more likely to undergo US for work-up of ovarian torsion. Copyright © 2016 Elsevier Inc. All rights reserved.

In subfertile women with poor ovarian reserve undergoing IVF does a mild ovarian stimulation strategy lead to comparable ongoing pregnancy rates in comparison to a conventional ovarian stimulation strategy? A mild ovarian stimulation strategy in women with poor ovarian reserve undergoing IVF leads to similar ongoing pregnancy rates as a conventional ovarian stimulation strategy. Women diagnosed with poor ovarian reserve are treated with a conventional ovarian stimulation strategy consisting of high-dose gonadotropins and pituitary downregulation with a long mid-luteal start GnRH-agonist protocol. Previous studies comparing a conventional strategy with a mild ovarian stimulation strategy consisting of low-dose gonadotropins and pituitary downregulation with a GnRH-antagonist have been under powered and their effectiveness is inconclusive. This open label multicenter randomized trial was designed to compare one cycle of a mild ovarian stimulation strategy consisting of low-dose gonadotropins (150 IU FSH) and pituitary downregulation with a GnRH-antagonist to one cycle of a conventional ovarian stimulation strategy consisting of high-dose gonadotropins (450 IU HMG) and pituitary downregulation with a long mid-luteal GnRH-agonist in women of advanced maternal age and/or women with poor ovarian reserve undergoing IVF between May 2011 and April 2014. Couples seeking infertility treatment were eligible if they fulfilled the following inclusion criteria: female age ≥35 years, a raised basal FSH level >10 IU/ml irrespective of age, a low antral follicular count of ≤5 follicles or poor ovarian response or cycle cancellation during a previous IVF cycle irrespective of age. The primary outcome was ongoing pregnancy rate per woman randomized. Analyses were on an intention-to-treat basis. We randomly assigned 195 women to the mild ovarian stimulation strategy and 199 women to the conventional ovarian stimulation strategy. Ongoing pregnancy rate was 12.8% (25/195) for mild ovarian stimulation versus 13.6% (27/199) for conventional ovarian stimulation leading to a risk ratio of 0.95 (95% CI: 0.57-1.57), representing an absolute difference of -0.7% (95% CI: -7.4 to 5.9). This 95% CI does not extend below the predefined threshold of 10% for inferiority. The duration of ovarian stimulation was significantly lower in the mild ovarian stimulation strategy than in the conventional ovarian stimulation strategy (mean difference -1.2 days, 95% CI: -1.88 to -0.62). Also, a significantly lower amount of gonadotropins was used in the mild simulation strategy, with a mean difference of 3135 IU (95% CI: -3331 to -2940). A limitation of our study was the lack of data concerning the cryopreservation of surplus embryos, so we are not informed on cumulative pregnancy rates. Another limitation is that we were not able to follow up on the ongoing pregnancies in all centers, so we are not informed on live birth rates. The results are directly applicable in daily clinical practice and may lead to considerable cost savings as high dosages of gonadotropins are not necessary in women with poor ovarian reserve undergoing IVF. A health economic analysis of our data planned to test the hypothesis that mild ovarian stimulation strategy is more cost-effective than the conventional ovarian stimulation strategy is underway.

This study aimed to compare the outcomes of controlled ovarian stimulation (COS) with corifollitropin alfa versus daily recombinant follicle-stimulating hormone (rRFSH) or highly purified human menopausal gonadotropin (HP-HMG) in patients undergoing in vitro fertilization (IVF) cycles based on gonadotropin-releasing hormone (GnRH) antagonist protocols. The primary endpoints were total number of oocytes and mature oocytes. This retrospective study looked into 132 controlled ovarian stimulation cycles from IVF or oocyte cryopreservation performed in a private human reproduction center between January 1 and December 31, 2014. Enrollment criteria: women aged < 40 years submitted to COS with corifollitropin alfa 100µg or 150µg (n = 26) and rFSH or HP-HMG in the first seven days of treatment with daily doses of 150-225 IU (n = 106); all subjects were on GnRH antagonist protocols. The groups had similar mean ages and duration of stimulation. The mean number ± standard deviation of total aspirated oocytes and MII oocytes was 11.9±10 and 10.3±7.9 in the corifollitropin alfa group, and 10.9±7.2 and 8.6±5.7 in the group on rFSH or HMG (p>0.05). There were no significant differences in fertilization (76.9% vs. 76.8%, p=1.0), biochemical pregnancy (66.7% vs. 47.2%, p=0.1561) or embryo implantation rates (68.7% vs. 50%, p=0.2588) between the groups using corifollitropin alfa and rFSH or HMG, respectively. Corifollitropin alfa seems to be as effective as rFSH or HP-HMG when used in the first seven days of ovulation induction for patients undergoing assisted reproduction in GnRH antagonist protocols.

To investigate the clinical outcome and endocrinological characteristics of progestin-primed ovarian stimulation (PPOS) using 4 versus 10 mg of medroxyprogesterone acetate (MPA) per day in infertile women with normal ovary reserve. A randomised parallel controlled trial. Tertiary-care academic medical centre. A cohort of 300 infertile women undergoing in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) treatment. Human menopausal gonadotropin (hMG; 225 iu per day) and MPA (group A, 10 mg per day; group B, 4 mg per day) were started simultaneously from cycle day 3 onwards. Ovulation was co-triggered by human chorionic gonadotropin (hCG; 1000 iu) and gonadotropin-releasing hormone agonist (GnRH agonist; 0.1 mg) when dominant follicles matured. Viable embryos were cryopreserved for later frozen embryo transfer (FET) in both groups. The primary outcome measure was the number of oocytes retrieved. Secondary outcomes included the incidence of a premature surge in luteinising hormone (LH), the number of viable embryos, and clinical pregnancy outcomes. The number of oocytes retrieved and viable embryos were similar between two groups (9.8 ± 6.3 versus 9.6 ± 5.9; 4.2 ± 2.6 versus 3.7 ± 3.0; P > 0.05). No significant difference was found in clinical pregnancy rate (58.0 versus 48.7%) and live birth rate per participant (48.7 versus 42.0%; P > 0.05). No premature LH surge and ovarian hyperstimulation syndrome (OHSS) occurred in either group. Progestin-primed ovarian stimulation (PPOS) using 4 or 10 mg of MPA per day was comparable in terms of the number of oocytes retrieved and pregnancy outcome after FET. The administration of 4 mg of MPA per day was sufficient to prevent an untimely LH rise in women undergoing IVF/ICSI treatment. An RCT confirmed similar pregnancy outcome in P-primed ovarian stimulation with a daily dose of 4 or 10 mg MPA. © 2017 Royal College of Obstetricians and Gynaecologists.

The objective of this study was to investigate the effects of low-dose hCG supplementation on ICSI outcomes and controlled ovarian stimulation (COS) cost. Three hundred and thirty patients undergoing ICSI were split into groups according to the COS protocol: (i) control group (n = 178), including patients undergoing conventional COS treatment; and (ii) low-dose hCG group (n = 152), including patients undergoing COS with low-dose hCG supplementation. Lower mean total doses of FSH administered and higher mean oestradiol level and mature oocyte rates were observed in the low-dose hCG group. A significantly higher fertilization rate, high-quality embryo rate and blastocyst formation rate were observed in the low-dose hCG group as compared to the control group. The miscarriage rate was significantly higher in the control group compared to the low-dose hCG group. A significantly lower incidence of OHSS was observed in the low-dose hCG group. There was also a significantly lower gonadotropin cost in the low-dose hCG group as compared to the control group ($1235.0 ± 239.0×$1763.0 ± 405.3, p < 0.001). The concomitant use of low-dose hCG and FSH results in a lower abortion rate and increased number of mature oocytes retrieved, as well as improved oocyte quality, embryo quality and blastocyst formation and reduced FSH requirements.

To evaluate the clinical value of basal anti-Müllerian hormone (AMH) measurements compared with other available determinants, apart from chronologic age, in the prediction of ovarian response to gonadotrophin stimulation. Prospective cohort study. Tertiary referral center for reproductive medicine and an IVF unit. Women undergoing their first cycle of controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF). Basal levels of FSH and AMH as well as antral follicle count (AFC) were measured in 165 subjects. All patients were followed prospectively and their cycle outcomes recorded. Predictive value of FSH, AMH, and AFC for extremes of ovarian response to stimulation. Out of the 165 women, 134 were defined as normal responders, 15 as poor responders, and 16 as high responders. Subjects in the poor response group were significantly older then those in the other two groups. Anti-Müllerian hormone levels and AFC were markedly raised in the high responders and decreased in the poor responders. Compared with FSH and AFC, AMH performed better in the prediction of excessive response to ovarian stimulation-AMH area under receiver operating characteristic curve (ROC(AUC)) 0.81, FSH ROC(AUC) 0.66, AFC ROC(AUC) 0.69. For poor response, AMH (ROC(AUC) 0.88) was a significantly better predictor than FSH (ROC(AUC) 0.63) but not AFC (ROC(AUC) 0.81). AMH prediction of ovarian response was independent of age and PCOS. Anti-Müllerian hormone cutoffs of >3.75 ng/mL and <1.0 ng/mL would have modest sensitivity and specificity in predicting the extremes of response. Circulating AMH has the ability to predict excessive and poor response to stimulation with exogenous gonadotrophins. Overall, this biomarker is superior to basal FSH and AFC, and has the potential to be incorporated in to work-up protocols to predict patient's ovarian response to treatment and to individualize strategies aiming at reducing the cancellation rate and the iatrogenic complications of COH.

Abstract Connective tissue components – collagen types I, III and IV – surrounding the ovarian follicles undergo drastic changes during ovulation. Abnormal collagen synthesis and increased volume and density of ovarian stroma characterize the polycystic ovary syndrome (PCOS). During the ovulatory process, collagen synthesis is regulated by prolyl hydroxylase and lysyl oxidase (LOX) activity in ovarian follicles. LOX catalyzes collagen and elastin cross-linking and plays essential role in coordinating the control of ovarian extracellular matrix (ECM) during follicular development. We have recently shown accumulation of advanced glycation end products (AGEs), molecules that stimulate ECM production and abnormal collagen cross-linking, in ovarian tissue. However, the possible link between LOX and AGEs-induced signalling in collagen production and stroma formation in ovarian tissue from PCOS remains elusive. The present study investigates the hypothesis of AGE signalling pathway interaction with LOX gene activity in polycystic ovarian (PCO) tissue. We show an increased distribution and co-localization of LOX, collagen type IV and AGE molecules in the PCO tissue compared to control, as well as augmented expression of AGE signalling mediators/effectors, phospho(p)-ERK, phospho(p)-c-Jun and nuclear factor κB (NF-κB) in pathological tissue. Moreover, we demonstrate binding of AGE-induced transcription factors, NF-κB and activator protein-1 (AP-1) on LOX promoter, indicating a possible involvement of AGEs in LOX gene regulation, which may account for the documented increase in LOX mRNA and protein levels compared to control. These findings suggest that deposition of excess collagen in PCO tissue that induces cystogenesis may, in part, be due to AGE-mediated stimulation of LOX activity. PMID:19583806

Does ovarian reserve and ovarian response to ovarian stimulation in women with cancer undergoing oocyte vitrification for fertility preservation vary according to the type of malignancy? Retrospective cohort study including 105 women aged between 18 and 40 years, who were referred for fertility preservation (oocyte vitrification) between 2013 and 2016. The women were divided into three groups: breast cancer, lymphoma or other cancer. All of them had been recently diagnosed with cancer, with gonadotoxic treatment scheduled, and had oocyte vitrification after ovarian stimulation with antagonist protocol. Baseline antral follicle count and anti-Müllerian hormone were no different between women with breast cancer, lymphoma or other cancer. The number of cancelled cycles for poor ovarian response was similar between the groups. The number of FSH units per mature oocyte, the number of mature oocytes (metaphase II) retrieved, and the oocyte maturity rate were not significantly different between the three groups. As the type of cancer does not seem to significantly affect ovarian reserve and ovarian response to ovarian stimulation, our results do not support the relevance of integrating this parameter when establishing ovarian stimulation protocol for oocyte vitrification cycle in women with cancer.

Abstract The aim of this study was to explore the effect of clomiphene citrate (CC) on the cycle characteristics and outcomes of obese women with polycystic ovarian syndrome (PCOS) undergoing ovarian stimulation for in vitro fertilization (IVF). This is a retrospective cohort study, and it was conducted at the tertiary-care academic medical center. This study included 174 obese PCOS patients undergoing IVF. In the study group (n = 90), CC and human menopausal gonadotropin (HMG) were administered simultaneously beginning on cycle day 3, while in control group (n = 84) HMG was used only. Both of the 2 groups used medroxyprogesterone acetate (MPA) for preventing premature luteinizing hormone (LH) surges. Ovulation was cotriggered by a GnRH agonist and hCG when dominant follicles matured. The primary outcome measure was the number of oocytes retrieved. Secondary outcomes included the number of top-quality embryos, maturation rate, fertilization rate, cleavage rate, incidence of premature LH surge, and OHSS. The study group received obviously lower total HMG dose [1650 (975–4800) vs 2025 (1350–3300) IU, P = 2.038E–4] but similar HMG duration. While the antral follicle count (AFC) is higher in study group, the number of oocytes retrieved and top-quality embryos are remarkably less [5 (0–30) vs 13 (0–42), P = 6.333E–5; 2 (0–14) vs 3.5 (0–15), P = .003; respectively]. The mature oocyte rate is higher in study group (P = .036). No significant differences were detected in fertilization rate and cleavage rate between 2 groups. CC has a positive influence on cycle characteristics, but might be correlated with the impaired IVF outcomes (less oocytes retrieved and top quality embryos, lower oocyte retrieval rate) in obese PCOS patients undergoing IVF, when HMG and MPA are used simultaneously.

A critical body mass of adipose tissue is essential for the normal development of female reproductive functions. Leptin, an adipocyte-derived hormone encoded by the 'Ob' gene has been proposed as a peripheral signal indicating the adequacy of nutritional status for reproductive functions. It is reported as a direct regulator of gametogenic and steroidogenic potential of ovary. Though leptin is widely present in reproductive tissues, its relationship to reproductive hormones is still poorly understood. Present investigation attempts to explore ovarian response to secretory profile of leptin and its impact on pregnancy outcome in women undergoing controlled ovarian hyperstimulation for in vitro fertilization and embryo transfer (IVF-ET). Patients enrolled for IVF-ET underwent pituitary-ovarian suppression by 'Long Protocol' GnRH-agonist downregulation followed by ovarian stimulation. Sera were procured at different phases of IVF-ET for the assay of estradiol, progesterone, human chorionic gonadotropin, and for leptin. Ovarian follicular fluids were also assayed for leptin. Luteinized granulosa cells were cultured in vitro to evaluate their steroidogenic potential. Statistical analyses were done by student's t-test, ANOVA, and Chi-square tests as applicable. All results were expressed as Mean ± SE. P values < 0.05 were considered significant. Positive correlation was observed between serum and ovarian follicular fluid leptin. A negative correlation was noted between the serum leptin levels and endometrial thickness. Elevated leptin response may exert adverse impacts on pregnancy success during IVF-ET possibly by modulating uterine receptivity.

To evaluate the risk of postoperative complications related to HA-CMC use in patients undergoing optimal cytoreductive surgery for primary and recurrent ovarian, fallopian tube, and peritoneal cancers. A single institution retrospective review identified all patients undergoing optimal (≤1 cm) cytoreductive surgery for primary or recurrent ovarian, fallopian tube, and peritoneal cancers between 1/95 and 12/08. Operative details and post-operative complications (<30 days) were extracted from the medical record. Fisher's exact test, Mann-Whitney-U, and multiple regression analyses were performed to identify factors, including HA-CMC use, associated with post-operative complications. Three hundred seventy-five cases were analyzed: HA-CMC was utilized in 168 debulking procedures. There was no difference in the incidence of overall morbidity for patients with HA-CMC compared to those without HA-CMC (OR 1.07; 95% CI: 0.68-1.67). On univariate analysis, application of HA-CMC increased the risk of pelvic abscess (OR 2.66; 95% CI: 1.21-5.86), particularly in the primary surgery setting (OR 4.65; 95% CI: 1.67-12.98) and in patients undergoing hysterectomy (OR 3.36; 95% CI: 1.18-9.53). After controlling for confounding factors using multiple linear regression, HA-CMC use approached statistical significance in predicting an increased risk of pelvic abscess but not major postoperative morbidity. HA-CMC adhesion barrier placement at the time of optimal cytoreductive surgery for ovarian, fallopian tube, and peritoneal cancer is not associated with major postoperative complications but may be associated with increased risk of pelvic abscess.

The aim of this systematic review was to assess the evidence from randomised controlled trials (RCTs) on the efficacy, effectiveness and safety of acupuncture in women with polycystic ovarian syndrome (PCOS) undergoing in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). We searched a total of 15 databases through October 2015. The participants were women with PCOS (diagnosed using the Rotterdam criteria) undergoing IVF or ICSI. Eligible trials were those with intervention groups receiving manual acupuncture (MA) or electroacupuncture (EA), and control groups receiving sham acupuncture, no treatment or other treatments. Outcomes included the clinical pregnancy rate (CPR), live birth rate (LBR), ongoing pregnancy rate (OPR) and incidence of ovarian hyperstimulation syndrome (OHSS) and adverse events (AEs). For statistical pooling, the risk ratio (RR) and its 95% (confidence interval) CI was calculated using a random effects model. Four RCTs including 430 participants were selected. All trials compared acupuncture (MA/EA) against no treatment. Acupuncture significantly increased the CPR (RR 1.33, 95% CI 1.03 to 1.71) and OPR (RR 2.03, 95% CI 1.08 to 3.81) and decreased the risk of OHSS (RR 0.63, 95% CI 0.42 to 0.94); however, there was no significant difference in the LBR (RR 1.61, 95% CI 0.73 to 3.58). None of the RCTs reported on AEs. Acupuncture may increase the CPR and OPR and decrease the risk of OHSS in women with PCOS undergoing IVF or ICSI. Further studies are needed to confirm the efficacy and safety of acupuncture as an adjunct to assisted reproductive technology in this particular population.

Growth Hormone Supplementation in the Luteal Phase Before Microdose GnRH Agonist Flare Protocol for In Vitro Fertilization.

2015-09-01

Growth hormone (GH) acts in both early and late follicular development to stimulate the proliferation and differentiation of granulosa cells and to increase the production of estradiol in animal and human ovaries. Investigators have therefore explored GH supplementation to improve outcomes in women undergoing in vitro fertilization, with the greatest interest in women with diminished ovarian reserve. Recent meta-analyses indicate that GH supplementation can be beneficial for poor responders undergoing IVF. In most studies, GH has been given concomitantly with gonadotropins during the follicular phase; this may not be optimal, since follicular recruitment begins during the preceding luteal phase. We therefore wished to examine the effect of GH supplementation in the luteal phase before controlled ovarian stimulation (COH) with a microdose GnRH agonist flare (MDF) protocol in women undergoing in vitro fertilization. We performed a retrospective matched case-control study of patients undergoing treatment at a private IVF facility between June 2012 and July 2013. Patients identified as poor responders to COH were offered adjuvant GH treatment as part of their ovarian stimulation regimen. The patients in the experimental group chose to take GH, 3.33 mg daily by subcutaneous injection for 14 days, before starting COH. All patients had an MDF stimulation protocol using 450 IU of follicle stimulating hormone (FSH) daily. A total of 42 women were included in the study. There were 14 women in the experimental group (GH) and 28 controls (C) matched for age, BMI, and day 3 FSH level. There was no difference between the groups in clinical pregnancy rate (GH = 29%, C = 32%, P = 0.99), number of mature oocytes retrieved (GH = 2.5, C = 5.0, P = 0.13), cycle cancellation rate (GH = 21%, C = 14%, P = 0.88), duration of COH (GH = 10.1, C = 10.1, P = 0.93), or mean peak estradiol level (GH = 4174 pmol/L, C = 5105 pmol/L, P = 0.44). The administration of growth hormone during the luteal phase before a microdose GnRH agonist flare protocol for in vitro fertilization did not improve outcomes in "poor responder" patients.

Epithelial ovarian cancer (EOC) is the most lethal gynecological cancer. Several approaches of active and passive immunotherapy for EOC have been studied. The aim of this systematic review was to assess the clinical efficacy of specific immunotherapy in patients with EOC. We found 4524 references in seven databases and we included ten controlled clinical trials with 2285 patients with EOC reporting five active immunotherapeutic agents and three passive immunotherapies. Meta-analysis of six studies showed that overall there was not any significant difference in overall survival and recurrence-free survival between patients undergoing specific immunotherapy and those in control group. Most of the studies we evaluated reported a positive outcome from treatment with specific immunotherapy, although this was not significant.

Costs of in vitro fertilisation (IVF) are high, which is partly due to the use of follicle stimulating hormone (FSH). FSH is usually administered in a standard dose. However, due to differences in ovarian reserve between women, ovarian response also differs with potential negative consequences on pregnancy rates. A Markov decision-analytic model showed that FSH dose individualisation according to ovarian reserve is likely to be cost-effective in women who are eligible for IVF. However, this has never been confirmed in a large randomised controlled trial (RCT). The aim of the present study is to assess whether an individualised FSH dose regime based on an ovarian reserve test (ORT) is more cost-effective than a standard dose regime. Multicentre RCT in subfertile women indicated for a first IVF or intracytoplasmic sperm injection cycle, who are aged < 44 years, have a regular menstrual cycle and no major abnormalities at transvaginal sonography. Women with polycystic ovary syndrome, endocrine or metabolic abnormalities and women undergoing IVF with oocyte donation, will not be included. Ovarian reserve will be assessed by measuring the antral follicle count. Women with a predicted poor response or hyperresponse will be randomised for a standard versus an individualised FSH regime (150 IU/day, 225-450 IU/day and 100 IU/day, respectively). Participants will undergo a maximum of three stimulation cycles during maximally 18 months. The primary study outcome is the cumulative ongoing pregnancy rate resulting in live birth achieved within 18 months after randomisation. Secondary outcomes are parameters for ovarian response, multiple pregnancies, number of cycles needed per live birth, total IU of FSH per stimulation cycle, and costs. All data will be analysed according to the intention-to-treat principle. Cost-effectiveness analysis will be performed to assess whether the health and associated economic benefits of individualised treatment of subfertile women outweigh the additional costs of an ORT. The results of this study will be integrated into a decision model that compares cost-effectiveness of the three dose-adjustment strategies to a standard dose strategy. The study outcomes will provide scientific foundation for national and international guidelines. NTR2657.

We conducted a descriptive study to identify the symptoms, emotional status, and quality of life experienced by hospitalized ovarian cancer patients undergoing chemotherapy, and influencing the factors of symptom clusters on their quality of life. A total of 192 patients who had been diagnosed with ovarian cancer and received adjuvant chemotherapy after surgery more than once from 2 university hospitals with over 800 beds located in the Seoul and Gyeonggi areas of South Korea were included in this study. Using a structured questionnaire, the symptoms, emotional status, and quality of life by these patients were investigated from May 2012 to June 2013. We identified the following 7 symptom clusters among ovarian cancer patients undergoing chemotherapy: psychological distress, fatigue-pain, abdominal discomfort, flu-like symptoms, fluid accumulation, and peripheral neuropathy. Patients with a high level of anxiety or depression experienced all symptoms at a higher level, and the 7 symptom clusters influenced all aspects of the patients' quality of life. This study provides to need interventions for the quality of life of ovarian cancer patients need to include the management of not only the physical symptoms and treatment-related side effects, but also the changes in their emotional status and daily lives.

This retrospective cohort study evaluated the cumulative live birth rate in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in-vitro fertilisation (IVF) treatment. We studied 104 women with PCOS, 184 with PCO and 576 age-matched controls undergoing the first IVF treatment cycle between 2002 and 2009. The main outcome measure was cumulative live birth in the fresh plus all the frozen embryo transfers combined after the same stimulation cycle. Women in both the PCOS (n = 104) and isolated PCO groups (n = 184) had higher ovarian response parameters compared to age-matched controls (n = 576), and higher rates of withholding fresh embryo transfer for risk of ovarian hyperstimulation syndrome (OHSS). The actual incidence of moderate to severe OHSS was significantly higher in the PCOS (11.5 %) but not the isolated PCO group (8.2%) compared to controls (4.9%). The live birth rates in the fresh cycle were comparable among the 3 groups, but the PCOS group had a significantly higher miscarriage rate compared to the other 2 groups. Cumulative live birth rate was significantly higher in the isolated PCO group (60.3%), but not the PCOS group (50.0%), compared to controls (47.5%). Women in the isolated PCO group, but not the PCOS group, had a significantly higher cumulative live birth rate compared to controls. This could be explained by the quantitative effect of the higher number of transferable embryos obtained per stimulation cycle, which is uncompromised by the unfavourable embryo competence otherwise observed in PCOS.

Does methotrexate administration for ectopic pregnancy after in vitro fertilization impact ovarian reserve or ovarian responsiveness?

To evaluate the effects of methotrexate (MTX) on the future fertility of women undergoing IVF by comparing ovarian reserve and ovarian responsiveness in the IVF cycle before and after an ectopic pregnancy (EP) treated with MTX. Retrospective cohort study. Private reproductive endocrinology and infertility practice. Sixty-six women undergoing IVF before and after receiving MTX for an EP. Methotrexate administration and ovarian stimulation. Markers of ovarian reserve (day 3 FSH, antral follicle count), measures of ovarian responsiveness (duration of stimulation, peak E2 level, total dose of gonadotropins, number of oocytes retrieved, fertilization rate), and time from MTX administration to subsequent IVF cycle. There were no differences after MTX administration in body mass index (BMI), FSH, or antral follicle count. A greater dose of gonadotropins was used in the cycle after MTX, but there were no differences in numbers of oocytes retrieved or high quality embryos transferred. As expected, there was a slight increase in age in the subsequent IVF cycle. The pregnancy rates (PR) were comparable to the average PRs within the practice when combining all age groups. Methotrexate remains the first line of therapy for medical management of asymptomatic EP and does not compromise ovarian reserve, ovarian responsiveness, or IVF success in subsequent cycles.

The aim of this study was to investigate a possible role for interleukin-6 (IL-6) and tumour necrosis factor (TNF-alpha) as pre-operative markers for the diagnosis of ovarian torsion. Twenty consecutive patients admitted to the gynaecological emergency room with suspected clinical diagnosis of ovarian torsion were prospectively assigned to the study. Blood samples were drawn pre-operatively and examined for serum concentrations of IL-6 and TNF-alpha. Surgeons were blinded to laboratory results prior to laparoscopy. The pre-operative diagnosis of ovarian torsion was confirmed during an urgent diagnostic laparoscopy in 8 (40%) patients. The surgical diagnosis among the remaining 12 patients was a large ovarian cyst not in torsion. In six out of eight (75.0%) patients with ovarian torsion serum IL-6 concentrations were elevated. None of the 12 patients without torsion had elevated serum IL-6 concentrations. This difference was statistically significant (P < 0.001). There was no significant difference in the proportion of women with elevated serum TNF-alpha concentrations, two of eight (25.0%) patients with torsion and four of 12 (33.3%) control cases. Elevated serum IL-6 concentrations, but not serum TNF-alpha concentrations, were significantly associated with the occurrence of ovarian torsion. In patients with vague clinical signs of ovarian torsion, serum IL-6 might help to distinguish which patients should undergo diagnostic laparoscopy.

Women undergoing surgery for ovarian cancer are severely ill and are high users of health services. Contributing to these increased utilization rates are the multiple modalities used to treat ovarian cancer and the complications and side effects from those treatments. The purpose of this study was to evaluate the effectiveness of an intervention provided by advanced practice nurses and a psychiatric consultation-liaison nurse on patients' self-report of healthcare utilization compared with an attention control intervention in women undergoing surgery for a suspected diagnosis of ovarian cancer. A two-group, experimental, longitudinal design was used to compare women who were assigned randomly to the intervention group or to an attention control group at baseline within 48 hours after surgery and 1, 3, and 6 months after surgery. Healthcare utilization was measured as the number of self-reported inpatient admissions and outpatient visits, including emergency room visits, oncology outpatient visits, and primary care visits. Nurse interventions consisted of 16 contacts: symptom management, counseling, education, direct nursing care, coordination of resources, and referrals. The attention control interventions consisted of nine contacts that included instructions on use of a symptom management toolkit and strategies on how to manage symptoms. There were no differences in hospitalizations and oncology outpatient visits between the two groups. The main finding of this study was a significant difference in the number of primary care visits between the two groups. Women in the attention control group went to their primary care providers more often than the intervention group. The women who reported more visits also reported more depressive symptoms. In addition, a trend was found in the number of emergency room visits between the two groups. The intervention group visited the emergency room more often because the nurse instructed patients to go when they recognized symptoms that needed urgent care after hours. Women in the intervention group appropriately used the emergency room to manage their problems after hours, whereas more women in the attention control group reported significantly more primary care visits. These findings highlight the need for healthcare providers representing various disciplines to coordinate services across specialties, especially for women who have depressive symptoms.

Long-Term Safety of Letrozole and Gonadotropin Stimulation for Fertility Preservation in Women With Breast Cancer

Kim, Jayeon; Turan, Volkan

2016-01-01

Context and Objective: There has been increased attention to the issue of fertility preservation (FP). We aimed to investigate the long-term safety of FP via controlled ovarian stimulation with letrozole supplementation (COSTLES) prior to breast cancer treatment. Design, Setting, and Participants: This is a prospective, nonrandomized, controlled study conducted between the years 2002 and 2014. A total of 337 women diagnosed with stage 3 or less invasive breast cancer were enrolled during a FP consultation before chemotherapy. Of those, 120 elected to undergo COSTLES for FP prior to chemotherapy (FP group). The remaining 217 patients did not undergo any FP procedure and served as the controls. Main Outcome Measure: The primary end point was cancer recurrence defined as the detection of locoregional tumor (chest wall, regional nodal disease), distant metastases, or contralateral invasive breast cancer. Results: The baseline characteristics at enrollment were similar between the FP and control groups except for the less frequent lymph node involvement (P = .02) in the former. The mean follow-up after diagnosis was 5.0 years in the FP group and 6.9 years in the control group. In the FP group, the hazard ratio for recurrence after ovarian stimulation was 0.77 (95% confidence interval 0.28–2.13), and the survival was not compromised compared with controls (P = .61). Neither BRCA gene mutation status (P = .57) nor undergoing FP before or after breast surgery (P = .44) affected survival outcomes in the FP group. Likewise, none of the tumor characteristics including the estrogen receptor status affected the survival rates after the COSTLES. Conclusion: COSTLES is unlikely to cause a substantially increased recurrence risk in breast cancer during the 5 years after diagnosis. PMID:26751194

Ovarian Cancer Is an Imported Disease: Fact or Fiction?

PubMed Central

Kuhn, Elisabetta; Kurman, Robert J.

2012-01-01

The cell of origin of ovarian cancer has been long debated. The current paradigm is that epithelial ovarian cancer (EOC) arises from the ovarian surface epithelium (OSE). OSE is composed of flat, nondescript cells more closely resembling the mesothelium lining the peritoneal cavity, with which it is continuous, rather than the various histologic types of ovarian carcinoma (serous, endometrioid, and clear cell carcinoma), which have a Müllerian phenotype. Accordingly, it has been argued that the OSE undergoes a process termed “metaplasia” to account for this profound morphologic transformation. Recent molecular and clinicopathologic studies not only have failed to support this hypothesis but also have provided evidence that EOC stems from Müllerian-derived extraovarian cells that involve the ovary secondarily, thereby calling into question the very existence of primary EOC. This new model of ovarian carcinogenesis proposes that fallopian tube epithelium (benign or malignant) implants on the ovary to give rise to both high-grade and low-grade serous carcinomas, and that endometrial tissue implants on the ovary and produces endometriosis, which can undergo malignant transformation into endometrioid and clear cell carcinoma. Thus, ultimately EOC is not ovarian in origin but rather is secondary, and it is logical to conclude that the only true primary ovarian neoplasms are germ cell and gonadal stromal tumors analogous to tumors in the testis. If this new model is confirmed, it has profound implications for the early detection and treatment of “ovarian cancer.” PMID:22506137

Cyclic AMP-dependent modification of gonad-selective TAF(II)105 in a human ovarian granulosa cell line.

PubMed

Wu, Yimin; Lu, Yunzhe; Hu, Yanfen; Li, Rong

2005-11-01

In response to gonadotropins, the elevated level of intracellular-cyclic AMP (cAMP) in ovarian granulosa cells triggers an ordered activation of multiple ovarian genes, which in turn promotes various ovarian functions including folliculogenesis and steroidogenesis. Identification and characterization of transcription factors that control ovarian gene expression are pivotal to the understanding of the molecular basis of the tissue-specific gene regulation programs. The recent discovery of the mouse TATA binding protein (TBP)-associated factor 105 (TAF(II)105) as a gonad-selective transcriptional co-activator strongly suggests that general transcription factors such as TFIID may play a key role in regulating tissue-specific gene expression. Here we show that the human TAF(II)105 protein is preferentially expressed in ovarian granulosa cells. We also identified a novel TAF(II)105 mRNA isoform that results from alternative exon inclusion and is predicted to encode a dominant negative mutant of TAF(II)105. Following stimulation by the adenylyl cyclase activator forskolin, TAF(II)105 in granulosa cells undergoes rapid and transient phosphorylation that is dependent upon protein kinase A (PKA). Thus, our work suggests that pre-mRNA processing and post-translational modification represent two important regulatory steps for the gonad-specific functions of human TAF(II)105.

Endometrial injury to overcome recurrent embryo implantation failure: a systematic review and meta-analysis.

PubMed

Potdar, Neelam; Gelbaya, Tarek; Nardo, Luciano G

2012-12-01

Mechanical endometrial injury (biopsy/scratch or hysteroscopy) in the cycle preceding ovarian stimulation for IVF has been proposed to improve implantation in women with unexplained recurrent implantation failure (RIF). This is a systematic review and meta-analysis of studies comparing the efficacy of endometrial injury versus no intervention in women with RIF undergoing IVF. All controlled studies of endometrial biopsy/scratch or hysteroscopy performed in the cycle preceding ovarian stimulation were included and the primary outcome measure was clinical pregnancy rate. Pooling of seven controlled studies (four randomized and three non-randomized), with 2062 participants, showed that local endometrial injury induced in the cycle preceding ovarian stimulation is 70% more likely to result in a clinical pregnancy as opposed to no intervention. There was no statistically significant heterogeneity in the methods used, clinical pregnancy rates being twice as high with biopsy/scratch (RR 2.32, 95% CI 1.72-3.13) as opposed to hysteroscopy (RR 1.51, 95% CI 1.30-1.75). The evidence is strongly in favour of inducing local endometrial injury in the preceding cycle of ovarian stimulation to improve pregnancy outcomes in women with unexplained RIF. However, large randomized studies are required before iatrogenic induction of local endometrial injury can be warranted in routine clinical practice. Some women undergoing IVF treatment fail to conceive despite several attempts with good-quality embryos and no identifiable reason. We call this 'recurrent implantation failure' (RIF) where the embryo fails to embed or implant within the lining of the womb. Studies have shown that inducing injury to the lining of the womb in the cycle before starting ovarian stimulation for IVF can help improve the chances of achieving pregnancy. Injury can be induced by either scratching the lining of the womb using a biopsy tube or by telescopic investigation of the womb using a camera. We performed a collective review of the available good-quality studies that used the above two methods in the cycle prior to starting ovarian stimulation for IVF. We pooled results from seven studies, which included 2062 women with RIF and assessed the difference in clinical pregnancy rates for those undergoing injury to the womb lining compared with no injury prior to IVF. The results suggest that inducing injury is 70% more likely to result in a clinical pregnancy as opposed to no treatment. Furthermore, scratching of the lining was 2-times more likely to result in a clinical pregnancy compared with telescopic evaluation of the lining of the womb. This study suggests that in women with RIF, inducing local injury to the womb lining in the cycle prior to starting ovarian stimulation for IVF can improve pregnancy outcomes. However, large studies are required before this can be warranted in routine clinical practice. Copyright © 2012 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

Minimal stimulation protocol using letrozole versus microdose flare up GnRH agonist protocol in women with poor ovarian response undergoing ICSI.

2013-02-01

To compare the IVF outcomes of letrozole/antagonist and microdose GnRH agonist flare up protocols in poor ovarian responders undergoing intracytoplasmic sperm injection. A randomized controlled trial was performed in patients with one or more previous failed IVF cycles in which four or less oocytes were retrieved when the gonadotrophin starting dose was at least 300 IU/day. Sixty patients were randomized by computer-generated list to receive either letrozole/antagonist (mild stimulation) n = 30 or GnRH-a protocol (microdose flare) n = 30. Both groups were similar with respect to background and hormonal characteristics (age, duration of infertility, BMI, FSH, LH and E2). The clinical pregnancy rate per cycle was similar in both groups (13.3 vs. 16.6%; OR = 0.769; 95% CI = 0.185, 3.198). The doses of used gonadotropins and the number of stimulation days were significantly lower in the letrozole/antagonist protocol. The peak E2 level on the day of hCG, the endometrial thickness, the retrieved oocytes, the number of fertilized oocytes, the number of transferred embryos and the cancellation rate were statistically similar in both groups. The letrozole/antagonist protocol is a cost-effective and patient-friendly protocol that may be used in poor ovarian responders for IVF/ICSI.

Patients with genetic susceptibility to breast and ovarian cancer are eligible for risk-reduction surgery. Surgical morbidity of risk-reduction mastectomy (RRM) with concurrent bilateral salpingo-oophorectomy (BSO) is unknown. Outcomes in these patients were compared to patients undergoing RRM without BSO using a large multi-institutional database. A retrospective cohort analysis was conducted using the American College of Surgeon's National Surgical Quality Improvement Program (NSQIP) 2007-2016 datasets, comparing postoperative morbidity between patients undergoing RRM with patients undergoing RRM with concurrent BSO. Patients with genetic susceptibility to breast/ovarian cancer undergoing risk-reduction surgery were identified. The primary outcome was 30-day postoperative major morbidity. Secondary outcomes included surgical site infections, reoperations, readmissions, length of stay, and venous thromboembolic events. A multivariate analysis was performed to determine predictors of postoperative morbidity and the adjusted effect of concurrent BSO on morbidity. Of the 5470 patients undergoing RRM, 149 (2.7%) underwent concurrent BSO. The overall rate of major morbidity and postoperative infections was 4.5% and 4.6%, respectively. There was no significant difference in the rate of postoperative major morbidity (4.5% vs 4.7%, p = 0.91) or any of the secondary outcomes between patients undergoing RRM without BSO vs. those undergoing RRM with concurrent BSO. Multivariable analysis showed Body Mass Index (OR 1.05; p < 0.001) and smoking (OR 1.78; p = 0.003) to be the only predictors associated with major morbidity. Neither immediate breast reconstruction (OR 1.02; p = 0.93) nor concurrent BSO (OR 0.94; p = 0.89) were associated with increased postoperative major morbidity. This study demonstrated that RRM with concurrent BSO was not associated with significant additional morbidity when compared to RRM without BSO. Therefore, this joint approach may be considered for select patients at risk for both breast and ovarian cancer.

Safety and usefulness of cryopreservation of ovarian tissue to preserve fertility: a 12-year retrospective analysis.

Do the benefits of ovarian tissue cryopreservation outweigh the risks for patients seeking to preserve fertility before gonadotoxic treatment in various indications? In >90% of the patients undergoing cryopreservation of ovarian tissue, oncological treatment was associated with a reduced ovarian reserve and in 30% of patients, premature ovarian failure (POF) occurred within 5 years. Ovarian tissue cryopreservation is an effective fertility preservation option, especially for pre-pubertal patients and patients who have a short time between diagnosis of a disease and gonadotoxic treatment. This study retrospectively analysed ovarian function and fertility recovery rates, as well as ovarian tissue characteristics, of patients who underwent ovarian tissue cryopreservation at Erasme Hospital between 1999 and 2011. A total of 225 patients referred from 15 Belgian oncological units underwent cryopreservation of ovarian tissue before gonadotoxic therapy for malignant or benign diseases. There were 28 patients (12.4%) who died during follow-up due to recurrence of disease. One severe adverse event occurred during anaesthesia for ovarian tissue collection, leading to the death of the patient. Ovarian function and fertility outcomes were available for 114 patients including 13 girls who were pre-pubertal at the time of the procedure. Eight patients had undergone ovarian tissue transplantation in order to restore their fertility after remission of the disease. Breast cancer and haematological disease were the most frequent indications for ovarian tissue cryopreservation. Overall, 90% of post-pubertal patients were diagnosed with poor ovarian reserve (AMH < 0.5 ng/ml) after a mean of 50 months of follow-up (11-125 months), including 30% with POF (FSH > 40 IU/ml). Breast cancer patients had a lower rate of POF than did post-pubertal patients with haematological diseases (11 versus 34.5%, respectively), despite the older age (mean 31 versus 23.5 years old, respectively) of the breast cancer patients. Ovarian function returned in 71 post-pubertal patients without the need for grafts of cryopreserved tissue. Spontaneous pregnancies were reported for 33 of them, leading to 34 live births. Among the 13 pre-pubertal patients who reached pubertal age during the follow-up, 10 had POF. Eight patients received cryopreserved ovarian grafts to reverse POF and three of them have already become pregnant. This study is a retrospective analysis. The cohort was not compared with a control group of patients who did not undergo the procedure. After careful evaluation of the surgical risks, ovarian tissue cryopreservation can be proposed as an efficient option to preserve the fertility of children and young adults facing gonadotoxic therapies. However, alternative procedures such as oocyte or embryo cryopreservation should be considered as first options especially for older patients or if there is high risk of neoplastic cells within the ovaries.

Ovarian hyperstimulation syndrome is a rare, but potentially life-threatening iatrogenic disorder arising from ovulation induction or ovarian hyperstimulation for assisted reproduction techniques. We report a case of a 26-year-old multiparous woman, an anonymous egg donor, who died a few hours after undergoing a procedure to donate eggs at an in vitro fertilization clinic. Her husband alleged that medical negligence had led to her death. The autopsy confirmed death due to ovarian hyperstimulation syndrome. We know of no previous descriptions of fatal ovarian hyperstimulation syndrome in an anonymous egg donor in medico-legal literature. © The Author(s) 2016.

Symptom clustering and quality of life in patients with ovarian cancer undergoing chemotherapy.

2017-10-01

The symptom clusters in patients with ovarian cancer undergoing chemotherapy have not been well evaluated. We investigated the symptom clusters and effects of symptom clusters on the quality of life of patients with ovarian cancer. We recruited 210 ovarian cancer patients being treated with chemotherapy and used a descriptive cross-sectional study design to collect information on their symptoms. To determine inter-relationships among symptoms, a principal component analysis with varimax rotation was performed based on the patient's symptoms (fatigue, pain, sleep disturbance, chemotherapy-induced peripheral neuropathy, anxiety, depression, and sexual dysfunction). All patients had experienced at least two domains of concurrent symptoms, and there were two types of symptom clusters. The first symptom cluster consisted of anxiety, depression, fatigue, and sleep disturbance symptoms, while the second symptom cluster consisted of pain and chemotherapy-induced peripheral neuropathy symptoms. Our subgroup cluster analysis showed that ovarian cancer patients with higher-scoring symptoms had significantly poorer quality of life in both symptom cluster 1 and 2 subgroups, with subgroup-specific patterns. The symptom clusters were different depending on age, age at disease onset, disease duration, recurrence, and performance status of patients with ovarian cancer. In addition, ovarian cancer patients experienced different symptom clusters according to cancer stage. The current study demonstrated that there is a specific pattern of symptom clusters, and symptom clusters negatively influence the quality of life in patients with ovarian cancer. Identifying symptom clusters of ovarian cancer patients may have clinical implications in improving symptom management. Copyright © 2017 Elsevier Ltd. All rights reserved.

Short-term changes in hormonal profiles after laparoscopic ovarian laser evaporation compared with diagnostic laparoscopy for PCOS.

Which reproductive endocrine changes are attributed exclusively to laparoscopic ovarian drilling in polycystic ovarian syndrome (PCOS)? Laser evaporation-specific endocrine effects were the prevention of an immediate increase in inhibin B and a sustained decrease in testosterone, androstenedione and anti-Müllarian hormone (AMH). All ovarian drilling procedures result in reproductive endocrine changes. It is not known which of these changes are the result of ovarian drilling and which are related to the surgery per se. This prospective controlled study was performed at an outpatient academic fertility clinic. Between 2007 and 2010, a total of 21 oligo- or amenorrheic PCOS patients were included. Included were oligo- or amenorrheic PCOS patients with all three of the Rotterdam criteria and luteinizing hormone (LH) >6.5 U/l. All PCOS patients had an indication for diagnostic surgery due to subfertility. There were 12 PCOS patients who chose to undergo ovarian laser evaporation (CO2 laser, 25 W, 20 times/ovary) and 9 PCOS who chose a diagnostic laparoscopy only (controls). Reproductive endocrinology was measured before, and until 5 days after, surgery, and four gonadotrophin-releasing hormone (GnRH) 'double pulse' tests were included. The main outcome measures were changes in reproductive endocrinology and pituitary sensitivity/priming to GnRH after laser evaporation compared with diagnostic laparoscopy only. In the first hours after surgery, both groups showed an increase in LH, follicle stimulating hormone, estrogen and a decrease in testosterone, androstenedione, AMH and insulin growth factor-1 (P < 0.05). Inhibin B increased in the laparoscopy only group (P < 0.05). In the first days after surgery, testosterone, androstenedione and AMH remained at lower than baseline levels exclusively in the laser group (P < 0.05). Pituitary sensitivity/priming to GnRH was not altered after either laser evaporation or laparoscopy only. The limitations of this study are the short follow-up period and the relatively small groups. The strength of this study is the integrally measured endocrine profiles in combination with an optimal control group of PCOS patients undergoing diagnostic laparoscopy only. Interestingly, most of the immediate endocrine changes after laser evaporation could be related to the surgical context and not to the ovarian drilling procedure itself.

In vitro fertilisation treatment and factors affecting success.

PubMed

Huang, Jack Yu Jen; Rosenwaks, Zev

2012-12-01

The efficacy of assisted reproductive technologies has improved significantly over the past decades. The main indications for in vitro fertilisation include tubal obstruction, severe male-factor infertility, severe endometriosis, ovulatory dysfunction, diminished ovarian reserve, and infertility of unexplained cause. In vitro fertilisation has also become an effective treatment option for couples wishing to undergo pre-implantation genetic diagnosis or screening, and for those wishing to cryopreserve their oocytes or embryos for preservation of fertility. The management of women in late reproductive age poses a major challenge; the optimum in vitro fertilisation treatment for poor responders remains elusive. The success of in vitro fertilisation treatment can be optimised by taking an individualised, patient-centered approach to controlled ovarian hyperstimulation. Key components involve selection of an appropriate controlled ovarian protocol, close-cycle monitoring, adjustment of gonadotropin dosage to avoid hyper-response, and individualised timing of human chorionic gonadotropin injection. Future directions of assisted reproductive technologies include development of non-invasive embryo selection methods, use of transcriptomics, proteomics, metabolomics, and time-lapse imaging technologies.

Background Costs of in vitro fertilisation (IVF) are high, which is partly due to the use of follicle stimulating hormone (FSH). FSH is usually administered in a standard dose. However, due to differences in ovarian reserve between women, ovarian response also differs with potential negative consequences on pregnancy rates. A Markov decision-analytic model showed that FSH dose individualisation according to ovarian reserve is likely to be cost-effective in women who are eligible for IVF. However, this has never been confirmed in a large randomised controlled trial (RCT). The aim of the present study is to assess whether an individualised FSH dose regime based on an ovarian reserve test (ORT) is more cost-effective than a standard dose regime. Methods/Design Multicentre RCT in subfertile women indicated for a first IVF or intracytoplasmic sperm injection cycle, who are aged < 44 years, have a regular menstrual cycle and no major abnormalities at transvaginal sonography. Women with polycystic ovary syndrome, endocrine or metabolic abnormalities and women undergoing IVF with oocyte donation, will not be included. Ovarian reserve will be assessed by measuring the antral follicle count. Women with a predicted poor response or hyperresponse will be randomised for a standard versus an individualised FSH regime (150 IU/day, 225-450 IU/day and 100 IU/day, respectively). Participants will undergo a maximum of three stimulation cycles during maximally 18 months. The primary study outcome is the cumulative ongoing pregnancy rate resulting in live birth achieved within 18 months after randomisation. Secondary outcomes are parameters for ovarian response, multiple pregnancies, number of cycles needed per live birth, total IU of FSH per stimulation cycle, and costs. All data will be analysed according to the intention-to-treat principle. Cost-effectiveness analysis will be performed to assess whether the health and associated economic benefits of individualised treatment of subfertile women outweigh the additional costs of an ORT. Discussion The results of this study will be integrated into a decision model that compares cost-effectiveness of the three dose-adjustment strategies to a standard dose strategy. The study outcomes will provide scientific foundation for national and international guidelines. Trial registration NTR2657 PMID:22989359

Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. Retrospective study (Canadian Task Force classification II-2). Tertiary center. Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. Laparoscopic and open surgical staging. Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. Copyright © 2016 AAGL. Published by Elsevier Inc.

This prospective cohort study was conducted on 80 patients with clomiphene citrate (CC)-resistant polycystic ovary syndrome undergoing laparoscopic ovarian drilling (LOD). Pre- and post-LOD ovarian reserve parameters (anti-Mullerian hormone: AMH, ovarian volume: OV, and antral follicle count: AFC) and ovarian stromal blood flow indices (Vascularization index: VI, flow index: FI, and vascularization flow index: VFI) were measured to explore the effect of LOD and to find out the correlation between serum AMH and different clinical, hormonal, and ultrasonic variables. There was a highly significant reduction of the serum AMH (p < .001) after LOD with significant reduction in OV, AFC and vascular indices (VI, FI and VFI) of the right and left ovaries (p < .05). LOD significantly reduced ovarian reserve parameters (AMH, OV and AFC) and ovarian stromal blood flow indices (VI, FI and VFI) with no observed correlation between AMH levels and Doppler indices.

Update on fertility preservation in young women undergoing breast cancer and ovarian cancer therapy.

The purpose of the article is to review the available options for fertility preservation in patients with breast and ovarian cancer, and the special issues faced by BRCA mutation carriers. Future fertility is an important consideration for many young patients with cancer. There are both experimental and standard available strategies for patients with breast and ovarian cancer to preserve fertility, and each has potential advantages and disadvantages. Embryo cryopreservation is widely available with a highly successful track record. Improvements in laboratory techniques have led to oocyte cryopreservation recently being recategorized as nonexperimental. Conservative gynecologic surgery is a standard consideration for patients with stage I ovarian cancer who desire future fertility. Ovarian tissue cryopreservation as well as ovarian suppression with luteinizing hormone-releasing hormone analogs during chemotherapy are considered experimental methods at this time, although recent data suggest both safety and efficacy for the use of luteinizing hormone-releasing hormone analogs in women receiving (neo)adjuvant chemotherapy for breast cancer. Special issues should be considered for women with BRCA mutations because of the need to undergo preventive surgery at young age. Multidisciplinary teams and well functioning relationships between the oncology and reproductive units are crucial to manage the fertility issues of young women with cancer.

To evaluate the relationship between transforming growth factor (TGF)-β1 and its receptor, soluble endoglin (sENG), in the serum and follicular fluid of women with polycystic ovarian syndrome (PCOS) compared with that of non-PCOS normal ovulating women during controlled ovarian stimulation (COS). Prospective case-control study. Academic-affiliated assisted reproductive technology unit. Fourteen PCOS and 14 matched non-PCOS control women undergoing COS. Serum was collected on day 3 (baseline), day of hCG, and day of retrieval. Follicular fluid (FF) was collected on day of oocyte retrieval. ELISA was performed to determine TGF-β1 and sENG protein levels. Serum and FF levels of TGF-β1 and sENG. Serum TGF-β1 did not change significantly during COS but was increased in PCOS compared with non-PCOS women on day 3 and days of hCG administration and oocyte retrieval. Serum sENG increased after hCG administration only in the non-PCOS control group. In addition, serum sENG was decreased in PCOS compared with non-PCOS control women on the days of hCG and retrieval. Accordingly, the bioavailability of TGF-β1 (TGF-β1/sENG ratio) was increased in women with PCOS compared with non-PCOS controls at all three time points. No differences in either factor were noted in FF between groups. The increased TGF-β1 bioavailability in PCOS is not only due to increased TGF-β1 levels but also to decreased levels of its receptor, sENG. These data suggest that increased TGF-β1 bioavailability may contribute to the pathogenesis of PCOS and its increased risk for ovarian hyperstimulation.

To measure the levels of early follicular phase Anti-Mullerian hormone (AMH) in Indian patients of IVF and to evaluate the AMH as a predictive marker of ovarian response in assisted reproductive technology outcome. Sixty women (age 25-40 years) selected for in vitro fertilization treatment were included in this study. Analysis of day-2 serum samples was done for the AMH, FSH, Inhibin B, and LH by ELISA kit methods. USG was done for the antral follicle count (AFC) and oocytes' retrieval. Hormone parameters were compared and correlated with the oocytes' retrieval count and the AFC. The discriminant analysis was done to compare relevance of different parameters for predicting ovarian response. The Anti-Mullerian hormone showed a significant correlation with the oocytes' retrieval after ovulation induction for IVF (r = 0.648, p < 0.0001) and no correlation was seen with serum FSH, LH, and Inhibin. Serum AMH levels show 80 % sensitivity and 80 % specificity in predicting poor ovarian response. There is a significant correlation between day-2 serum AMH levels and the oocytes' retrieval count in women undergoing ovulation induction for IVF, and the AMH is a good marker as the negative predictive values for the success of ART. There is no correlation found between other hormonal ovarian reserve markers and the oocytes' retrieval count.

To investigate differences in ovarian reserve markers (antimüllerian hormone [AMH] and antral follicle count [AFC]) in Indian and Spanish women. Cross-sectional study. In vitro fertilization (IVF) clinics. Infertile Spanish (n=229) and Indian (n=236) women who underwent controlled ovarian stimulation for IVF from January to October 2012. None. Data on ovarian reserve markers and results after ovarian stimulation were collected. The mean age of women undergoing their first or second IVF cycle was significantly higher in Spanish than in Indian women (37.5±3.3 years vs. 31.5±3.8 years). Despite this 6-year age gap, AFCs were similar (9.5±4.7 vs. 9.9±4.6), as were day 3 FSH levels (7.5±4.5 IU/L vs. 6.9±2.3 IU/L). AMH levels were slightly lower in Spanish women (1.6±1.7 ng/mL vs. 2.5±1.6 ng/mL). Multivariate regression analysis showed that being Indian decreased AFC by 2.3, such that AFC in Indian women was similar to that in Spanish women 6.3 years older (95% confidence interval 3.39-1.10). Similar ovarian reserve markers and ovarian response were observed in women with a 6-year age difference in favor of the Spanish, suggesting ethnic differences in ovarian aging. Further research is needed to understand whether these differences are genetically induced or are caused by other variables, such as nutrition. Our results may help clinicians to counsel infertile women when discussing assisted reproductive technology outcomes according to age and ethnic background.

Evaluation of the effects of hyaluronic acid-carboxymethyl cellulose barrier on ovarian tumor progression

PubMed Central

2014-01-01

Background Hyaluronic acid is a prognostic factor in ovarian cancers. It is also a component of Hyaluronic Acid-Carboxymethyl Cellulose (HA-CMC) barrier, an anti-adhesion membrane widely used during abdominal surgeries in particular for ovarian carcinosis. 70% of patients who undergo ovarian surgery will relapse due to the persistence of cancer cells. This study’s objective was to determine the oncological risk from use of this material, in the presence of residual disease, despite the benefit gained by it decreasing post-surgical adhesions in order to provide an unambiguous assessment of its appropriateness for use in ovarian surgical management. Methods We assessed the effects of HA-CMC barrier on the in vitro proliferation of human ovarian tumor cell lines (OVCAR-3, IGROV-1 and SKOV-3). We next evaluated, in vivo in nude mice, the capacity of this biomaterial to regulate the tumor progression of subcutaneous and intraperitoneal models of ovarian tumor xenografts. Results We showed that HA-CMC barrier does not increase in vitro proliferation of ovarian cancer cell lines compared to control. In vivo, HA-CMC barrier presence with subcutaneous xenografts induced neither an increase in tumor volume nor cell proliferation (Ki67 and mitotic index). With the exception of an increased murine carcinosis score in peritoneum, the presence of HA-CMC barrier with intraperitoneal xenografts modified neither macro nor microscopic tumor growth. Finally, protein analysis of survival (Akt), proliferation (ERK) and adhesion (FAK) pathways highlighted no activation on the xenografts imputable to HA-CMC barrier. Conclusions For the most part, our results support the lack of tumor progression activation due to HA-CMC barrier. We conclude that the benefits gained from using HA-CMC barrier membrane during ovarian cancer surgeries seem to outweigh the potential oncological risks. PMID:24739440

Fertility after childhood haemopoietic stem cell transplant (HSCT) is a major concern. Conditioning regimens before HSCT present a high risk (>80%) of ovarian failure. Since 2000, we have proposed cryopreservation of ovarian tissue to female patients undergoing HSCT at our centre, to preserve future fertility. After clinical and haematological evaluation, the patients underwent ovarian tissue collection by laparoscopy. The tissue was analysed by histologic examination to detect any tumour contamination and then frozen following the slow freezing procedure and cryopreserved in liquid nitrogen. From August 2000 to September 2013, 47 patients planned to receive HSCT, underwent ovarian tissue cryopreservation. The median age at diagnosis was 11.1 years and at the time of procedure it was 13 years, respectively. Twenty-four patients were not pubertal at the time of storage, whereas 23 patients had already experienced menarche. The median time between laparoscopy and HSCT was 25 days. Twenty-six out of 28 evaluable patients (93%) developed hypergonadotropic hypogonadism at a median time of 23.3 months after HSCT. One patient required autologous orthotopic transplantation that resulted in one live birth. Results show a very high rate of iatrogenic hypergonadotropic hypogonadism, highlighting the need for fertility preservation in these patients.

Ovarian hyperstimulation syndrome is an iatrogenic complication of controlled ovarian stimulation. Early ovarian hyperstimulation syndrome occurs during luteal phase of controlled ovarian stimulation within 9 days after human chorionic gonadotropin trigger and reflects an acute consequence of this hormone on the ovaries. Late ovarian hyperstimulation syndrome occurs 10 or more days after human chorionic gonadotropin trigger and reflects increased endogenous human chorionic gonadotropin levels following pregnancy. Human chorionic gonadotropin stimulates granulosa-lutein cells to produce vascular endothelial growth factor messenger RNAs, which in turn raises serum vascular endothelial growth factor concentration and increases vascular permeability in women with ovarian hyperstimulation syndrome. Efforts to reduce the incidence and severity of ovarian hyperstimulation syndrome after oocyte retrieval, and in particular primary prevention efforts, are vital to prevent thrombogenesis and other serious complications. The objective of the study was to compare the efficacy of letrozole, an aromatase inhibitor, with aspirin in primary prevention of early ovarian hyperstimulation syndrome and to compare vascular endothelial growth factor levels between groups. Participants in this prospective randomized trial included 238 participants undergoing cryopreservation of the whole embryos after oocyte retrieval with at least 1 of the following high-risk factors for ovarian hyperstimulation syndrome: oocyte retrieval ≥25; estradiol level ≥5000 pg/mL on the day of human chorionic gonadotropin administration; and clinical or ultrasonographic evidence of ovarian hyperstimulation syndrome on the day of oocyte retrieval, such as ultrasonographic evidence of ascites. After human chorionic gonadotropin triggering, experimental (119 cases) and control (119 cases) groups received letrozole and aspirin, respectively, for 5 days. The 5 categories of ovarian hyperstimulation syndrome include no, yes-mild, yes-moderate, yes-severe, and yes-critical. The primary outcome was the incidence and severity of early ovarian hyperstimulation syndrome. The secondary outcome included vascular endothelial growth factor level both on the second and seventh day after the human chorionic gonadotropin trigger, and clinical and laboratory features of ovarian hyperstimulation syndrome symptoms. The incidence of ovarian hyperstimulation syndrome was significantly higher in women receiving aspirin, compared with letrozole (90.2% vs 80.4%, P = .044). Moderate and severe ovarian hyperstimulation syndrome was also higher in the aspirin group, 45.1%, compared with the letrozole group, 25.0% (P = .002). Moreover, the duration of luteal phase was shortened in letrozole group compared with aspirin group (8.1 ± 1.1 days vs 10.5 ± 1.9 days, P < .001). The vascular endothelial growth factor level was significantly higher in the letrozole-treated group than aspirin-treated group (0.49 ± 0.26 vs 0.42 ± 0.22, P = .029). Letrozole was more effective than aspirin in decreasing the incidence of moderate and severe early-onset ovarian hyperstimulation syndrome. Our results indicate that ovarian hyperstimulation syndrome might be caused through a luteolytic effect rather than through modulation of vascular endothelial growth factor, racing by a decline in estradiol and termination of early-onset ovarian hyperstimulation syndrome in advance in high-risk women with cryopreservation of the whole embryos.

A 39-year-old primiparous Japanese female was admitted to the obstetrical emergency department of our hospital because of respiratory distress resulting from a large amount of pleural effusion, soon after a caesarean delivery (CD) at another hospital. While she was undergoing the CD, a giant ovarian tumour was identified. However, the tumour could not be removed at that facility and she was transferred to our hospital. Three days after the CD, a left salpingo-oophorectomy was performed with the purpose of controlling pleural and peritoneal effusions. Based on her past treatment history and the information gathered from this surgery, recurrence of ovarian cancer was considered the final diagnosis. Earlier, at the age of 37 years, she had been diagnosed with stage IC ovarian adenocarcinoma arising from a mature cystic teratoma detected after a right salpingo-oophorectomy. These kinds of situations of accidental detection of recurrent advanced ovarian cancer in a newly pregnant patient in the emergency department are rare. Amongst them, we have identified an extremely rare case showing placental metastasis. The important lesson learnt from this case report is that detailed medical interviews and physical examinations are crucial when a pregnant woman visits a hospital without a letter of referral, especially in the third trimester of pregnancy.

To evaluate the effect of a gonadotropin-releasing hormone (GnRH) antagonist protocol using corifollitropin alfa in women undergoing assisted reproduction. Six hundred and eighty-six in vitro fertilization-embryo transfer (IVF)/intracytoplasmic sperm injection (ICSI) cycles were analyzed. In 113 cycles, folliculogenesis was induced with corifollitropin alfa and recombinant follicle stimulating hormone (rFSH), and premature luteinizing hormone (LH) surges were prevented with a GnRH antagonist. In the control group (573 cycles), premature LH surges were prevented with GnRH agonist injection from the midluteal phase of the preceding cycle, and ovarian stimulation was started with rFSH. The treatment duration, quality of oocytes and embryos, number of embryo transfer (ET) cancelled cycles, risk of ovarian hyperstimulation syndrome (OHSS), and the chemical pregnancy rate were evaluated in the two ovarian stimulation protocols. There were no significant differences in age and infertility factors between treatment groups. The treatment duration was shorter in the corifollitropin alfa group than in the control group. Although not statistically significant, the mean numbers of matured (86.8% vs. 85.1%) and fertilized oocytes (84.2% vs. 83.1%), good embryos (62.4% vs. 60.3%), and chemical pregnancy rates (47.2% vs. 46.8%) were slightly higher in the corifollitropin alfa group than in the control group. In contrast, rates of ET cancelled cycles and the OHSS risk were slightly lower in the corifollitropin alfa group (6.2% and 2.7%) than in the control group (8.2% and 3.5%), although these differences were also not statistically significant. Although no significant differences were observed, the use of corifollitropin alfa seems to offer some advantages to patients because of its short treatment duration, safety, lower ET cancellation rate and reduced risk of OHSS.

The aim of this study was to estimate the rate of ovarian metastases and recurrences among patients affected by locally advanced stage cancer patients (LACC), undergoing neoadjuvant chemotherapy (NACT) and radical surgery with conservation of ovaries. Retrospective evaluation of consecutive patients affected by LACC (stage IB2- IIB), treated by NACT followed by radical surgery at National Cancer Institute, Milan, Italy, between 1990-2015. Overall, 331 patients were included. Stage at presentation included stage IB2, IIA and IIB in 120 (36.3%), 63 (19%) and 148 (44.7%) patients, respectively. Main histotype was squamous cell carcinoma (n=265, 80.1%) followed by adenocarcinoma/adenosquamous (n=51, 15.4%), and more than half of patients had a grade 3 carcinoma . Overall, 102 (30.8%) women had at least one ovary preserved during surgery, while 229 (69.2%) had bilateral salpingo-oophorectomy. Comparing patients who had ovarian preservation with patients who had not, we observed that the two groups were comparable in terms of baseline characteristics. Survival outcomes were not influenced by ovarian preservation (disease-free (p=0.93) and overall (p=0.65) survivals). One (1%) woman had a localized ovarian recurrence. Our data suggest that ovarian preservation at the time of surgery is a safe option among women with LACC after NACT with no detrimental impact on oncologic outcome. Further prospective studies are warranted.

In vitro maturation of human oocytes for assisted reproduction.

To describe and evaluate the current practice of in vitro maturation of oocytes for assisted reproduction. Review of the available and relevant literature regarding in vitro maturation of oocytes. In vitro maturation of human oocytes retrieved from antral ovarian follicles is an emerging procedure quickly being incorporated into the realm of assisted reproductive technologies. This new technology has several potential advantages over traditional controlled ovarian hyperstimulation for IVF, such as reduction of costs by minimizing gonadotropin and GnRH analogue use, elimination of ovarian hyperstimulation syndrome, and simplicity of protocol. In vitro maturation of oocytes for assisted reproduction in human beings still is undergoing refinement but currently is providing efficacy and safety outcome comparable to that of traditional IVF in recent selected studies. Implementing in vitro maturation into an established IVF practice is feasible and requires only a few simple adjustments. Crucial to the advancement and optimization of the technology is a better understanding of how to maximize immature oocyte developmental competence and endometrial receptivity.

This was a prospective controlled study to compare the beneficial effects of office microlaparoscopic ovarian drilling (OMLOD) under augmented local anesthesia, as a new modality treatment option, compared to those following ovarian drilling with the conventional traditional 10-mm laparoscope (laparoscopic ovarian drilling, LOD) under general anesthesia. The study included 60 anovulatory women with polycystic ovary syndrome (PCOS) who underwent OMLOD (study group) and 60 anovulatory PCOS women, in whom conventional LOD using 10-mm laparoscope under general anesthesia was performed (comparison group). Transvaginal ultrasound scan and blood sampling to measure the serum concentrations of LH, FSH, testosterone and androstenedione were performed before and after the procedure. Intraoperative and postoperative pain scores in candidate women were evaluated during the office microlaparoscopic procedure, in addition to the number of candidates who needed extra analgesia. Women undergoing OMLOD showed good intraoperative and postoperative pain scores. The number of patients discharged within 2 h after the office procedure was significantly higher, without the need for postoperative analgesia in most patients. The LH:FSH ratio, mean serum concentrations of LH and testosterone and free androgen index decreased significantly after both OMLOD and LOD. The mean ovarian volume decreased significantly (P < 0.05) a year after both OMLOD and LOD. There were no significant differences in those results after both procedures. Intra- and postoperatively augmented local anesthesia allows outpatient bilateral ovarian drilling by microlaparoscopy without general anesthesia. The high pregnancy rate, the simplicity of the method and the faster discharge time offer a new option for patients with PCOS who are resistant to clomiphene citrate. Moreover, ovarian drilling could be performed simultaneously during the routine diagnostic microlaparoscopy and integrated into the fertility workup of these patients.

Ovarian cancer is the fifth leading cause of deaths due to cancer among women in the United States. In 2017, 22,440 women are expected to be diagnosed with ovarian cancer and 14,080 women will die with it. Currently used chemotherapies (Cisplatin or platinum/taxane combination) targets cancer cells, but spares cancer stem cells (CSCs), which are responsible for tumor relapse leading to recurrence of cancer. Aldehyde dehydrogenase I (ALDH1) positive cancer stem cells are one of the major populations in ovarian tumor and have been related to tumor progression and metastasis. In our studies, we observed expression of ALDH1 in both ovarian surface epithelium (OSE) and cortex with high levels of expression in OSE in normal ovary and benign (BN) tumor, compared to borderline (BL) and high grade (HG) ovarian tumors. In contrast, high levels of expression of ALDH1 were observed in cortex in BL and HG tumors compared to normal ovary and BN tumor. Withaferin A (WFA) alone or in combination with cisplatin (CIS) significantly inhibited the spheroid formation (tumorigenic potential) of isolated ALDH1 CSCs in vitro and significantly reduced its expression in tumors collected from mice bearing orthotopic ovarian tumor compared to control. Treatment of animals with CIS alone significantly increased the ALDH1 CSC population in tumors, suggesting that CIS targets cancer cells but spares cancer stem cells, which undergo amplification. WFA and CIS combination suppresses the expression of securin an "oncogene", suggesting that securin may serve as a downstream signaling gene to mediate the antitumor effects of WFA.

The association between ABO blood groups and ovarian reserve in infertile patients has been a point of controversy. The aim of this study was to assess the correlation of certain blood groups with ovarian reserve and response to treatment in patients undergoing infertility treatment. Retrospective medical record review. Infertility clinic in the assisted reproductive technology (ART) unit at King Faisal Specialist Hospital and Research Center, Riyadh Saudi Arabia. All patients under 40 years of age who attended the infertility clinic at a tertiary care centre in 2010 and underwent in vitro fertilization (IVF) treatment in 2010 and 2011 were divided into groups according to blood type, and clinical parameters were compared. The association between blood groups and ovarian reserve using day 3 luteinzing hormone (LH) and follicular stimulating hormone (FSH) levels, and antral follical count (AFC). In 424 patients who underwent 566 IVF cycles, age, LH, FSH and AFC were similar among the different blood groups (P=.9, .1, .5, respectively). with controlled ovarian stimulation, no difference was observed among the four groups in menopausal gonadotrophin (hMG) dose or the duration of stimulation. The number of oocytes retrieved, fertilization rate, cleavage rate, and number of embryos transferred were similar. There was no difference in the cancellation rate or pregnancy rate among the groups. There was no significant association between blood type and ovarian reserve or response during IVF treatment in our population. Anti-Mullerian hormone levels are best correlated with ovarian reserve testing. Unavailability of AMH levels. Retrospective design.

Antral follicle count (AFC) has been labeled as the most accurate biomarker to assess female fecundity. Unfortunately, no baseline Indian data exists, and we continue using surrogate values from the Western literature (inferred from studies on women, grossly different than Indian women in morphology and genetic makeup). (1) To establish the role of AFC as a function of ovarian reserve in fertility-proven and in subfertile Indian women. (2) To establish baseline cut-off AFC values for Indian women. Prospective observational case-control study. Thirty patients undergoing workup for infertility were included and compared to equal number of controls (women with proven fertility). The basal ovarian volume and AFC were measured by endovaginal. USG the relevant clinical data and hormonal assays were charted for every patient. SPSS platform was used to perform the Student's t-test and Mann-Whitney U-test for intergroup comparisons. Correlations were determined by Pearson's ranked correlation coefficient. Regression analysis revealed the highest correlation of AFC and age in fertile and infertile patients with difference in mean AFC of both the groups. Comparison of the data recorded for cases and controls showed no significant difference in the mean ovarian volume. AFC has the closest association with chronological age in normal and infertile Indian women. The same is lower in infertile women than in matched controls. Baseline and cut-off values in Indian women are lower than that mentioned in the Western literature.

Sarcopenia, severe skeletal muscle loss, has been identified as a prognostic factor in various malignancies. This study aims to investigate whether sarcopenia is associated with overall survival (OS) and surgical complications in patients with advanced ovarian cancer undergoing primary debulking surgery (PDS). Ovarian cancer patients (n = 216) treated with PDS were enrolled retrospectively. Total skeletal muscle surface area was measured on axial computed tomography at the level of the third lumbar vertebra. Optimum stratification was used to find the optimal skeletal muscle index cut-off to define sarcopenia (≤38.73 cm 2 /m 2 ). Cox-regression and Kaplan-Meier analysis were used to analyse the relationship between sarcopenia and OS. The effect of sarcopenia on the development of major surgical complications was studied with logistic regression. Kaplan-Meier analysis showed a significant survival disadvantage for patients with sarcopenia compared to patients without sarcopenia (p = 0.010). Sarcopenia univariably predicted OS (HR 1.536 (95% CI 1.105-2.134), p = 0.011) but was not significant in multivariable Cox-regression analysis (HR 1.362 (95% CI 0.968-1.916), p = 0.076). Significant predictors for OS in multivariable Cox-regression analysis were complete PDS, treatment in a specialised centre and the development of major complications. Sarcopenia was not predictive of major complications. Sarcopenia was not predictive of OS or major complications in ovarian cancer patients undergoing primary debulking surgery. However a strong trend towards a survival disadvantage for patients with sarcopenia was seen. Future prospective studies should focus on interventions to prevent or reverse sarcopenia and possibly increase ovarian cancer survival. Complete cytoreduction remains the strongest predictor of ovarian cancer survival.

The purpose of this study was to investigate whether a change in the follicular fluid metabolomics profile due to endometrioma is identifiable. Twelve women with ovarian endometriosis (aged<40 years, with a body mass index [BMI] of <30 kg/m 2 ) and 12 age- and BMI-matched controls (women with infertility purely due to a male factor) underwent ovarian stimulation for intracytoplasmic sperm injection (ICSI). Follicular fluid samples were collected from both of groups at the time of oocyte retrieval for ICSI. Next, nuclear magnetic resonance (NMR) spectroscopy was performed for the collected follicular fluids. The metabolic compositions of the follicular fluids were then compared using univariate and multivariate statistical analyses of NMR data. Univariate and multivariate statistical analyses of NMR data showed that the metabolomic profiles of the follicular fluids obtained from the women with ovarian endometriosis were distinctly different from those obtained from the control group. In comparison with the controls, the follicular fluids of the women with ovarian endometriosis had statistically significant elevated levels of lactate, β-glucose, pyruvate, and valine. We conclude that the levels of lactate, β-glucose, pyruvate, and valine in the follicular fluid of the women with endometrioma were higher than those of the controls.

Objective. This study aims to evaluate whether alpha-lipoic acid and/or coenzyme Q10 can protect the prepubertal ovarian tissue from ischemia-reperfusion injury in an experimental rat model of ovarian torsion. Materials and Methods. Forty-two female preadolescent Wistar-Albino rats were divided into 6 equal groups randomly. The sham group had laparotomy without torsion; the other groups had torsion/detorsion procedure. After undergoing torsion, group 2 received saline, group 3 received olive oil, group 4 received alpha-lipoic acid, group 5 received coenzyme Q10, and group 6 received both alpha-lipoic acid and coenzyme Q10 orally. The oxidant-antioxidant statuses of these groups were compared using biochemical measurement of oxidized/reduced glutathione, glutathione peroxidase and malondialdehyde, pathological evaluation of damage and apoptosis within the ovarian tissue, and immunohistochemical assessment of nitric oxide synthase. Results. The left ovaries of the alpha-lipoic acid + coenzyme Q10 group had significantly lower apoptosis scores and significantly higher nitric oxide synthase content than the left ovaries of the control groups. The alpha-lipoic acid + coenzyme Q10 group had significantly higher glutathione peroxidase levels and serum malondialdehyde concentrations than the sham group. Conclusions. The combination of alpha-lipoic acid and coenzyme Q10 has beneficial effects on oxidative stress induced by ischemia-reperfusion injury related to ovarian torsion.

Purpose: Women at familial/genetic ovarian cancer risk often undergo screening despite unproven efficacy. Research suggests each woman has her own CA125 baseline; significant increases above this level may identify cancers earlier than standard 6- to 12-monthly CA125 > 35 U/mL. Experimental Design: Data from prospective Cancer Genetics Network and Gynecologic Oncology Group trials, which screened 3,692 women (13,080 woman-screening years) with a strong breast/ovarian cancer family history or BRCA1/2 mutations, were combined to assess a novel screening strategy. Specifically, serum CA125 q3 months, evaluated using a risk of ovarian cancer algorithm (ROCA), detected significant increases above each subject's baseline, which triggered transvaginal ultrasound. Specificity and positive predictive value (PPV) were compared with levels derived from general population screening (specificity 90%, PPV 10%), and stage-at-detection was compared with historical high-risk controls. Results: Specificity for ultrasound referral was 92% versus 90% ( P = 0.0001), and PPV was 4.6% versus 10% ( P > 0.10). Eighteen of 19 malignant ovarian neoplasms [prevalent = 4, incident = 6, risk-reducing salpingo-oophorectomy (RRSO) = 9] were detected via screening or RRSO. Among incident cases (which best reflect long-term screening performance), three of six invasive cancers were early-stage (I/II; 50% vs. 10% historical BRCA1 controls; P = 0.016). Six of nine RRSO-related cases were stage I. ROCA flagged three of six (50%) incident cases before CA125 exceeded 35 U/mL. Eight of nine patients with stages 0/I/II ovarian cancer were alive at last follow-up (median 6 years). Conclusions: For screened women at familial/genetic ovarian cancer risk, ROCA q3 months had better early-stage sensitivity at high specificity, and low yet possibly acceptable PPV compared with CA125 > 35 U/mL q6/q12 months, warranting further larger cohort evaluation.

To compare surgical outcomes, cost-effectiveness, and patient satisfaction in women undergoing primary vaginal or laparoscopic ovarian cystectomy for benign ovarian cysts. Retrospective cohort control study (Canadian Task Force classification II-3). Gynecologic unit at a university-affiliated hospital. Fifty patients who underwent primary ovarian cystectomy either through the vaginal route via posterior colpotomy (n = 29) or laparoscopic route (n = 21). Nonmalignant ovarian cysts were initially determined by transvaginal ultrasonography and serum tumor markers. The index group of women (n = 29) underwent vaginal ovarian cystectomy via a posterior colpotomy incision, whereas the control group (n = 21) comprised women who had laparoscopic ovarian cystectomy using the traditional "grasp and peel" technique. The following outcomes were evaluated: duration of surgery, intraoperative complications, estimated blood loss, length of inpatient stay, and postoperative pain (visual analogue scale). The average cost of both surgical methods was calculated by factoring in theater time, equipment required, and the length of hospital stay. Patients were then surveyed to compare postoperative pain and satisfaction scores as well as the time taken to return to work (in days). The 2 groups had similar mean ages (35.79 vs 36.72 years) and cyst diameter (6.8 vs 6.6 cm) (p > .05 in both cases). Vaginal ovarian cystectomy took a mean of 13.7 minutes longer (91.7 vs 78.0 minutes, p < .001) to perform and resulted in a greater mean estimated blood loss (116.1 vs 95 mL, p < .001). The spillage rate in the index group was 6-fold less compared with control cases (6% ± 2.4% vs 35% ± 4.6, p < .01). Although patients from the index group spent a mean of 2 hours longer as inpatients (10.9 vs 8.9 hours, p < .001), they reported a lower mean visual analogue pain score (2.01/10 vs 3.95/10, p < .05) and higher patient satisfaction scores (8.2/10 vs 6.5/10, p < .001). Mean perioperative cost of women who underwent vaginal ovarian cystectomy was lower (£1690.13 vs 1761.67) and they returned to work quicker compared with the laparoscopic group (13.6 vs 39.2 days, p < .001). Vaginal ovarian cystectomies took longer to perform and led to longer inpatient stay. However, these women had less postoperative pain and reported higher satisfaction scores compared with laparoscopic ovarian cystectomy, with a quicker return to work. The vaginal approach is a viable and cost-effective alternative to the laparoscopic approach in carefully selected patients. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

To examine blood transfusion practices and develop a standardized bundle of interventions to address the high rate of perioperative red blood cell transfusion among patients with ovarian and endometrial cancer. This was a retrospective cohort study. Our primary aim was to determine whether an implemented bundled intervention was associated with a reduction in perioperative red blood cell transfusions among cases of laparotomy for cancer. Secondary aims included comparing perioperative demographic, surgical, complication, and cost data. Interventions included blood transfusion practice standardization using American Society of Anesthesiologists guidelines, an intraoperative hemostasis checklist, standardized intraoperative fluid status communication, and evidence-based use of tranexamic acid. Prospective data from women undergoing laparotomy for ovarian or endometrial cancer from September 28, 2015, to May 31, 2016, defined the study cohort and were compared with historical controls (September 1, 2014, to September 25, 2015). Outcomes were compared in the full unadjusted cohorts and in propensity-matched cohorts. In the intervention and historical cohorts, respectively, 89 and 184 women underwent laparotomy for ovarian cancer (n=74 and 152) or advanced endometrial cancer (n=15 and 32). Tranexamic acid was administered in 54 (60.7%) patients. The perioperative transfusion rate was lower for the intervention group compared with historical controls (18.0% [16/89] vs 41.3% [76/184], P<.001), a 56.4% reduction. This improvement in the intervention group remained significant after propensity matching (16.2% [13/80] vs 36.2% [29/80], P=.004). The hospital readmission rate was also lower for the intervention group compared with historical controls (1.1% [1/89] vs 12.5% [23/184], P=.002); however, this improvement did not attain statistical significance after propensity matching (1.2% [1/80] vs 7.5% [6/80], P=.12). Cost analysis demonstrated that this intervention was cost-neutral during index hospitalization plus 30-day follow-up. Application of a standardized bundle of evidence-based interventions was associated with reduced blood use in our gynecologic oncology practice.

Preservation of ovarian functions in woman with premature ovarian failure remains an issue in reproductive medicine. Hormone replacement therapy for maintaining endocrine functions, and cryopreservation of embryos or oocytes for those who wish pregnancy, are some of the choices. However, ovarian transplantation is a more physiological alternative, although problems related to ovarian ischemia have been reported. Herein, we investigated the viability of autologous transplantation of the ovarian tissue into the rat peritoneum, without vascular reanastomosis. Twenty animals in the study group had both ovaries excised, and each ovary was dissected into two halves. A half of an ovary was autotransplanted to the peritoneal surface, closely located to the left epigastric vessels. This simple procedure does not require surgical vascular reanastomosis while it maintains appropriate follicular growth and therefore should be further considered as an alternative for women undergoing oophorectomy, not only to maintain endocrine functions but also for fertility preservation.

Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is to determine the effect of endometrial scratching prior to a second fresh in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle on live birth rates in women with a failed first IVF/ICSI cycle. Multicenter randomized controlled trial in Dutch academic and non-academic hospitals. A total of 900 women will be included of whom half will undergo an endometrial scratch in the luteal phase of the cycle prior to controlled ovarian hyperstimulation using an endometrial biopsy catheter. The primary endpoint is the live birth rate after the 2 nd fresh IVF/ICSI cycle. Secondary endpoints are costs, cumulative live birth rate (after the full 2 nd IVF/ICSI cycle and over 12 months of follow-up); clinical and ongoing pregnancy rate; multiple pregnancy rate; miscarriage rate and endometrial tissue parameters associated with implantation failure. Multiple studies have been performed to investigate the effect of endometrial scratching on live birth rates in women undergoing IVF/ICSI cycles. Due to heterogeneity in both the method and population being scratched, it remains unclear which group of women will benefit from the procedure. The SCRaTCH trial proposed here aims to investigate the effect of endometrial scratching prior to controlled ovarian hyperstimulation in a large group of women undergoing a second IVF/ICSI cycle.

Screening for ovarian cancer with cancer antigen 125 (CA-125) and transvaginal ultrasound has an unknown effect on mortality. To evaluate the effect of screening for ovarian cancer on mortality in the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. Randomized controlled trial of 78,216 women aged 55 to 74 years assigned to undergo either annual screening (n = 39,105) or usual care (n = 39,111) at 10 screening centers across the United States between November 1993 and July 2001. Intervention The intervention group was offered annual screening with CA-125 for 6 years and transvaginal ultrasound for 4 years. Participants and their health care practitioners received the screening test results and managed evaluation of abnormal results. The usual care group was not offered annual screening with CA-125 for 6 years or transvaginal ultrasound but received their usual medical care. Participants were followed up for a maximum of 13 years (median [range], 12.4 years [10.9-13.0 years]) for cancer diagnoses and death until February 28, 2010. Mortality from ovarian cancer, including primary peritoneal and fallopian tube cancers. Secondary outcomes included ovarian cancer incidence and complications associated with screening examinations and diagnostic procedures. Ovarian cancer was diagnosed in 212 women (5.7 per 10,000 person-years) in the intervention group and 176 (4.7 per 10,000 person-years) in the usual care group (rate ratio [RR], 1.21; 95% confidence interval [CI], 0.99-1.48). There were 118 deaths caused by ovarian cancer (3.1 per 10,000 person-years) in the intervention group and 100 deaths (2.6 per 10,000 person-years) in the usual care group (mortality RR, 1.18; 95% CI, 0.82-1.71). Of 3285 women with false-positive results, 1080 underwent surgical follow-up; of whom, 163 women experienced at least 1 serious complication (15%). There were 2924 deaths due to other causes (excluding ovarian, colorectal, and lung cancer) (76.6 per 10,000 person-years) in the intervention group and 2914 deaths (76.2 per 10,000 person-years) in the usual care group (RR, 1.01; 95% CI, 0.96-1.06). Among women in the general US population, simultaneous screening with CA-125 and transvaginal ultrasound compared with usual care did not reduce ovarian cancer mortality. Diagnostic evaluation following a false-positive screening test result was associated with complications. Trial Registration clinicaltrials.gov Identifier: NCT00002540.

What is the final hormonal milieu of pre-ovulatory follicles of low-responder (LR) patients undergoing unstimulated cycles? Neither androgen secretion nor LH was impaired in pre-ovulatory follicles of LR women. Therapies currently used to improve ovarian response in LR women have an impact on the final hormonal follicular milieu, and these changes are believed to be partially responsible for determining the success rate in these women. Surprisingly, as far as we know, there is no report of the final hormonal profile of LR women undergoing unstimulated cycles or evidence that follicular androgen secretion in LR women is impaired. A prospective case-control study including 94 women, 36 normal controls and 58 LR patients (19 Young ≤ 35 years LR and 39 Aged >35 years LR) from 2009 to 2011. Fifty-eight LR women were divided into two groups: Young LR (age ≤ 35; n = 19) and Aged LR (ALR; age >35; n = 39). The control group (group C) comprised 36 egg donors undergoing an unstimulated cycle in our IVF unit. Serum and follicular fluid hormonal concentrations for estradiol (E₂), progesterone, testosterone and androstendione were measured. The spindle parameters of metaphase II oocytes generated from these groups were also analysed. Pre-ovulatory follicles from LR patients had similar androgenic and LH concentrations to those observed in the control group. However, higher intrafollicular concentrations of FSH and progesterone were observed in ALR. Moreover, no differences were found for the spindle evaluation of oocytes between groups by the Oosight technology. The controls were younger and had a lower BMI than the LR women. The sample size available restricted statistical power. This study suggests that the problem with LR women is not the final pre-ovulatory follicular androgen concentration since this is similar to normal responders, but in the ability to respond to controlled ovarian stimulation protocols. Therefore, efforts should be focused on long-interval androgen priming to potentially increase the recruitment of small antral follicles rather than increasing the intraovarian androgen levels within the current cycle.

Role of BRCA1 in Controlling Mitotic Arrest in Ovarian Cystadenoma Cells

Cancers that develop in BRCA1 mutation carriers are usually near tetraploid/polyploid. This led us to hypothesize that BRCA1 controls the mitotic checkpoint complex, as loss of such control could lead to mitotic errors resulting in tetraploidy/polyploidy with subsequent aneuploidy. We used an in vitro system mimicking pre-malignant conditions, consisting of cell strains derived from the benign counterparts of serous ovarian carcinomas (cystadenomas) and expressing SV40 large T antigen, conferring the equivalent of a p53 mutation. We previously showed that such cells undergo one or several doublings of their DNA content as they age in culture and approach the phenomenon of in vitro crisis. Here we show that such increase in DNA content reflects a cell cycle arrest possibly at the anaphase promoting complex, as evidenced by decreased BrdU incorporation and increased expression of the mitotic checkpoint complex. Down-regulation of BRCA1 in cells undergoing crisis leads to activation of the anaphase promoting complex and resumption of growth kinetics similar to those seen in cells before they reach crisis. Cells recovering from crisis after BRCA1 down-regulation become multinucleated, suggesting that reduced BRCA1 expression may lead to initiation of a new cell cycle without completion of cytokinesis. This is the first demonstration that BRCA1 controls a physiological arrest at the M phase apart from its established role in DNA damage response, a role that could represent an important mechanism for acquisition of aneuploidy during tumor development. This may be particularly relevant to cancers that have a near tetraploid/polyploid number of chromosomes. PMID:21792894

Ovarian transposition in young women and fertility sparing.

Ovarian transposition is a highly effective surgical procedure used to preserve ovarian function in premenopausal patients with cancers requiring postoperative or primary pelvic radiotherapy. Pelvic irradiation determines severe damage of ovarian DNA and iatrogenic ovarian failure with premature menopause, necessity of long-term hormone replacement therapy and infertility. We conducted an extensive research of the literature in Medline between January 2000 and April 2015 using the key-words "ovarian transposition radiotherapy", "radiotherapy gonadal function", radiotherapy fertility sparing". The population included young women with normal ovarian function affected by cancers that required pelvic radiotherapy. We have examined 32 articles reporting on 1189 women undergoing ovarian transposition. Median age was 32.5 years, follow up was median 48 months. The procedure has been performed in patients less than 40 years of age. Surgery has been achieved by laparotomy or laparoscoy. We have analyzed effects of radiotherapy on ovarian function. The proportion of women treated by ovarian transposition preserved ovarian function was 70%. About 86% of patients did not develop ovarian cysts and in 98-99% of cases did not occur any metastatic disease. Ovarian transposition is associated with significant preservation of ovarian function and a low frequency of complications as cysts and metastasis. In 31% of cases the procedure can fail. Further studies are needed to evaluate the efficacy of ovarian transposition and the follow up. Ovarian transposition should be discussed at the time of cancer diagnosis in every premenopausal woman requiring pelvic radiotherapy.

Breast cancer is the most common malignancy in women worldwide, and ovarian cancer is the most lethal gynecological malignancy. Women carrying a BRCA1/2 mutation have a very high lifetime risk of developing breast and ovarian cancer. The only effective risk-reducing strategy in BRCA-mutated women is a prophylactic surgery with bilateral mastectomy and bilateral salpingo-oophorectomy. However, many women are reluctant to undergo these prophylactic surgeries due to a consequent mutilated body perception, unfulfilled family planning, and precocious menopause. In these patients, an effective screening strategy is available only for breast cancer, but it only consists in close radiological exams with a significant burden for the health system and a significant distress to the patients. No biomarkers have been shown to effectively detect breast and ovarian cancer at an early stage. MicroRNAs (miRNAs) are key regulatory molecules operating in a post-transcriptional regulation of gene expression. Aberrant expression of miRNAs has been documented in several pathological conditions, including solid tumors, suggesting their involvement in tumorigenesis. miRNAs can be detected in blood and urine and could be used as biomarkers in solid tumors. Encouraging results are emerging in gynecological malignancy as well, and suggest a different pattern of expression of miRNAs in biological fluids of breast and ovarian cancer patients as compared to healthy control. Aim of this study is to highlight the role of the urinary miRNAs which are specifically associated with cancer and to investigate their role in early diagnosis and in determining the prognosis in breast and ovarian cancer.

To compare the oocyte and embryo yield associated with GnRH-agonist triggers vs. hCG triggers in cancer patients undergoing controlled ovarian stimulation (COS) for fertilization preservation. Retrospective cohort study. Academic center. Cancer patients undergoing COS with letrozole and gonadotropins or gonadotropin-only protocols for oocyte or embryo cryopreservation. Gonadotropin-releasing hormone agonist or hCG trigger. Number of metaphase II (MII) oocytes or two-pronuclei (2PN) embryos available for cryopreservation were primary outcomes. Separate multivariate linear regression models were used to assess the effect of trigger type on the primary outcomes, after controlling for confounders of interest. A total of 341 patients were included, 99 (29.0%) in the GnRH-agonist group and 242 (71%) in the hCG group. There was no difference in the baseline demographics of patients receiving GnRH-agonist or hCG triggers. Within the letrozole and gonadotropins group (n = 269), the number (mean ± SD, 11.8 ± 5.8 vs. 9.9 ± 6.0) and percentage of MII oocytes (89.6% vs. 73.0%) available for cryopreservation was higher with GnRH-agonist triggers compared with hCG triggers. Similar results were noted with GnRH-agonist triggers in the gonadotropin-only group (n = 72) (i.e., a higher number [13.3 ± 7.9 vs. 9.3 ± 6.0] and percentage of MII oocytes [85.7% vs. 72.8%] available for cryopreservation). Multivariate linear regression demonstrated approximately three more MII oocytes and 2PN embryos available for cryopreservation in the GnRH-agonist trigger group, irrespective of cancer and COS protocol type. Utilization of a GnRH-agonist trigger increases the number of MII oocytes and 2PN embryos available for cryopreservation in cancer patients undergoing COS for fertility preservation.

A survey of the relation of hilus cell genesis and frequency of detection in ovaries to adenocarcinoma of the endometrium is presented. Results were based on the examination of 281 ovaries obtained from patients with endometrial carcinoma. The results showed that there was no statistical difference between the occurrence of hilus cells in the endometrial carcinoma group and a control group (33 and 25% respectively). However, if mode of treatment was taken into consideration, and patients undergoing irradiation for endometrial adenocarcinoma prior to operation separated into an individual group, there was a significant difference in the distribution of hilus cellsmore » in those patients as compared with the nonirradiated carcinoma group, at the level of 5%. The radiotherapy in these cases consisisted mainly of 50100 mg intracavitary Ra for approximates 72 hr. A surprisingly high incidence (60%) of ovarian hilus cells was found in patients who underwent radioinduced menopause for benign gynecologic conditions prior to developing adenocarcinoma of the endometrium. The incidence in all postmenopausal patients was only 37%. Ovarian hilus cells were more prevalent in postmenopausal women irrespective of endometrial carcinoma. Premenopausal women with endometrial carcinoma who received no irradiation prior to definitive operation are, therefore, the ideal subjects for further investigation of the relation between endometrial adenocarcinoma and ovarian hilus cells.

Gonadotropin-releasing hormone (GnRH) analogues are used routinely to prevent a premature luteinizing hormone (LH) surge in women undergoing assisted reproductive technology (ART) treatments. In contrast to GnRH agonists, antagonists produce rapid and reversible suppression of LH with no initial flare effect. To review the role of cetrorelix, the first GnRH antagonist approved for the prevention of premature LH surges during controlled ovarian stimulation in modern ART. A review of published literature on cetrorelix. Both multiple- and single-dose cetrorelix protocols were shown to be at least as effective as long GnRH agonist regimens for pituitary suppression in Phase II/III clinical trials. Furthermore, cetrorelix co-treatment resulted in similar live birth rates but a shorter duration of gonadotropin stimulation, a lower total gonadotropin dose requirement and lower incidence of ovarian hyperstimulation syndrome compared with long agonist regimens. A single-dose cetrorelix protocol further decreased the number of injections required. Preliminary studies have also produced promising data on the use of cetrorelix in modified ART protocols, such as frozen embryo transfer and donor oocyte recipient cycles. Cetrorelix offers a potential therapeutic alternative to GnRH agonists during controlled ovarian stimulation and has become an integral part of modern, patient-friendly reproductive medicine.

Gonadotropins used in controlled ovarian stimulation have been increasing in number. Beside the recombinant preparations such as rec-FSH, rec-LH and h-hMG human-derived preparations have entered the market. We decided to compare the effects of rec-FSH and HP-hMG with GnRHa on embryo quality and pregnancy outcome in women undergoing an IVF cycle. In this study, data of 87 patients who had applied to our center from 2007 to 2008 and who had met all inclusion criteria, were analyzed. The patients underwent controlled ovarian hyperstimulation with HP-hMG, rec-FSH following down-regulation with a GnRHa in a long protocol, selected according to determined criteria and acquired embryo via IVF transfer. Of the 87 patients, 44 were stimulated with rec-FSH and 43 with HP-hMG. Distribution of infertility causes was similar between the groups. Duration of gonadotropin administration (p=0.677, Student's t-test) and the total dose of gonadotropin received (p=0.392, Student's t-test) were similar between the two groups. The fertilization rate of the rec-FSH group was significantly higher than the HP-hMG group (p=0.001, Mann-Whitney U test). No significant differences were observed between the study groups in biochemical, clinical and ongoing pregnancy parameters. The higher oocyte yield with rec-FSH does not result in higher quality embryos. LH activity in combination with FSH activity positively affected the oocyte and embryo maturation. Therefore, when we consider the clinical and ongoing pregnancy rates there is no inferiority of HP-hMG in controlled ovarian stimulation.

As being overweight can impair female spontaneous fertility or after assisted reproductive technology (ART) cycles, the aim of this study was to compare in vitro fertilization (IVF) outcome according to women's body mass index (BMI). Retrospective study conducted from 2006 to 2009 in the IVF unit of Nantes University Hospital, France. 582 patients undergoing standard infertility workup and controlled ovarian stimulation were categorized according to BMI into two groups: group 1: normal weight (20-24.9 kg/m(2); n=409) and group 2: overweight and obese (≥25 kg/m(2); n=149). Basal hormonal status, smoking habitus, infertility duration, IVF cycle parameters and outcome were recorded. Basal LH, FSH and estradiol levels were higher in group 1 than group 2, but ovarian reserve markers were comparable across the two BMI groups. Higher doses of gonadotropins were required in group 2 to obtain equivalent ovarian response than in group 1. No difference was observed on ovarian response and embryonic parameters. Cycle outcome were not significantly different between both groups, but we found a strong trend towards increasing transfer cancellation and miscarriage rates in group 2. Although overweight and obesity do not compromise ovarian stimulation results whenever adaptation of recombinant FSH doses is made, our data suggest an increased risk of cancellation transfer and miscarriage rate, leading to poorer IVF outcome.

The consensus statements regarding first-line therapies in women with ovarian cancer, reached at the Fifth Ovarian Cancer Consensus Conference held in Tokyo, Japan, in November 2015 are reported. Three topics were reviewed and the following statements are recommended: (i) Surgery: the subgroups that should be considered in first-line ovarian cancer clinical trials should be (a) patients undergoing primary debulking surgery and (b) patients receiving neo-adjuvant chemotherapy. The amount of residual disease following surgery should further stratify patients into those with absent gross residual disease and others. (ii) Control arms for chemotherapy: for advanced stage ovarian cancer the standard is intravenous 3-weekly carboplatin and paclitaxel. Acceptable alternatives, which should be stratified variables in trials when more than one regimen is offered, include weekly paclitaxel plus 3-weekly carboplatin, the addition of bevacizumab to 3-weekly carboplatin and paclitaxel, and intraperitoneal therapy. (iii) Trial Endpoints: overall survival is the preferred primary endpoint for first-line clinical trials with or without a maintenance component. Progression-free survival (PFS) is an alternative primary endpoint, but if PFS is chosen overall survival must be measured as a secondary endpoint and PFS must be supported by additional endpoints, including predefined patient reported outcomes and time to first or second subsequent therapy. For neoadjuvant therapy, additional 'window of opportunity' endpoints should be included. © The Author 2017.

Optical imaging systems are robust, portable, relatively inexpensive, and have proven utility in detecting precancerous lesions in the lung, esophagus, colon, oral cavity and cervix. We describe the use of light-induced endogenous fluorescence (autofluorescence) in identifying preinvasive and occult carcinomas in ex vivo samples of human fallopian tube (FT) epithelium. Women undergoing surgery for an i) ovarian mass, ii) a history suggestive of hereditary breast-ovarian cancer, or iii) known serous ovarian cancer following neoadjuvant chemotherapy (NAC) were approached for informed consent. Immediately following surgery, FT's were photographed in reflectance and fluorescence at high resolution. Images included: (1) white-light reflectance of luminal/epithelial surface; (2) narrow-band green reflectance (570 nm) (3) green autofluorescence (405/436 nm excitation); and (4) blue autofluorescence (405 nm excitation). Areas revealing a loss of natural tissue fluorescence or marked increase in tissue microvasculature were recorded and compared to final histopathologic diagnosis (SEE-FIM protocol). Fifty-six cases involving one or both fallopian tubes underwent reflectance and fluorescence visualization. Nine cases were excluded, either secondary to non-ovarian primary pathology (7) or excessive trauma (2) rendering tissue interpretation impossible. Of the 47 cases remaining, there were 11 high grade serous (HGS) and 9 non-serous ovarian carcinomas undergoing primary debulking surgery, 5 serous carcinomas having received NAC, 8 benign ovarian tumors, and 14 women undergoing risk-reducing bilateral salpingo-oophorectomy (RRBSO). Methodology was feasible, efficient, and reproducible. TIC or carcinoma was identified in 7/11 HGS, 3/5 NAC, and 1/14 RRBSO. Optical images were reviewed to determine test positive or negative based on standardized criteria. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for the entire cohort (73%; 83%; 57%; 91%) and in a subgroup that excluded non-serous histology (87.5%; 92%; 78%; 96%). Abnormal FT lesions can be identified using ex vivo optical imaging technologies. With this platform, we will move towards genomic interrogation of identified lesions, and developing in vivo screening modalities via falloposcopy. Copyright © 2010 Elsevier Inc.

This study examined the efficacy of a group intervention, the Integrative Body-Mind-Spirit (I-BMS) intervention, which aims at improving the psychosocial and spiritual well-being of Chinese women undergoing their first IVF treatment cycle. The I-BMS intervention facilitates the search of meaning of life in the context of family and childbearing, as well as the letting go of high IVF expectations. A randomized controlled study of 339 women undergoing first IVF treatment cycle in a local Hong Kong hospital was conducted (intervention: n= 172; no-intervention control: n= 167). Assessments of anxiety, perceived importance of childbearing, and spiritual well-being were made at randomization (T(0) ), on the day starting ovarian stimulations (T(1)), and on the day undertaking embryo transfer (T(2)). Comparing T(0) and T(2), interaction analyses showed women who had received the intervention reported lower levels of physical distress, anxiety, and disorientation. They reported being more tranquil and satisfied with their marriage, and saw childbearing as less important compared to women in the control group. These findings suggest that I-BMS intervention was successful at improving the psychosocial and spiritual well-being of women undergoing their first IVF treatment cycle. This study highlights the importance of providing integrative fertility treatment that incorporates psychosocial and spiritual dimensions. ©2011 The British Psychological Society.

To identify predictors of ovarian conservation at hysterectomy and to examine the association of ovarian conservation and survival of young women with early-stage cervical cancer. This is a retrospective cohort study using the Surveillance, Epidemiology, and End Results Program to identify hysterectomy-based surgically treated patients with stage I cervical cancer diagnosed between 1983 and 2012 (N=16,511). Multivariable models were used to identify independent factors associated with ovarian conservation. Among the subgroup of 9,419 women younger than 50 years of age with stage I disease, survival outcomes and causes of death were examined for 3,908 (41.5%) women who underwent ovarian conservation at hysterectomy without radiotherapy. On multivariable analysis, age younger than 50 years, stage IA disease, and squamous histology were independent factors associated with ovarian conservation (all, P<.001). Among 5,526 women younger than 50 years of age with stage IA disease who underwent hysterectomy without radiotherapy, overall survival was significantly higher in patients undergoing ovarian conservation than in those undergoing oophorectomy (20-year rate, 93.5% compared with 86.8%, P<.001); cervical cancer-specific survival was similar between the patients who underwent ovarian conservation and those who underwent oophorectomy (98.8% compared with 97.8%, P=.12). On multivariable analysis, ovarian conservation remained an independent prognostic factor for improved overall survival (adjusted hazard ratio 0.63, 95% confidence interval [CI] 0.49-0.82, P=.001) and was independently associated with lower cumulative risks of death resulting from cardiovascular disease (20-year cumulative rate, 1.2% compared with 3.3%, adjusted hazard ratio 0.47, 95% CI 0.26-0.86, P=.014) and other chronic disease (0.5% compared with 1.4%, adjusted hazard ratio 0.24, 95% CI 0.09-0.65, P=.005) compared with oophorectomy. Both cervical cancer-specific survival (20-year rate, 93.1% compared with 92.0%, P=.37) and overall survival (86.7% compared with 84.6%, P=.12) were similar between ovarian conservation and oophorectomy among 3,893 women younger than 50 years of age with stage IB disease who underwent hysterectomy without radiotherapy. Among young women with stage IA cervical cancer, ovarian conservation at hysterectomy is associated with decreased all-cause mortality including death resulting from cardiovascular disease and other chronic diseases.

To study clinical efficacy of smoothing Gan reinforcing Shen (SGRS) method in treating poor response of diminished ovarian reserve (DOR) patients in in vitro fertilization and embryo, transfer (IVF-ET). Totally 84 DOR patients undergoing IVF-ET were assigned to the experimental group (SGRS Chinese herbs as adjuvant therapy) and the control group according to random digit table, 42 in each group. Patients in the control group received controlled ovarian hyperstimulation (COH) and IVF-ET. Those in the experimental group additionally received basic formula of SGRS method, one dose per day. The dose and use time of recombinant follicle-stimulating hormone (r-FSH) were recorded during ovarian stimulation process. On the injection day of human chorionic gonadotropin (HCG) and serum levels of estradiol (E2) on the oocyte retrieval day were determined using chemiluminescent method. E2 contents in the follicular fluid on the oocyte retrieval day were detected using ELISA. The total number of retrieved oocytes, the number of mature oocytes in metaphase II (M II), the number of normal fertilization [with two pronucleus (2PN)], the number of portable embryos, and the number of good quality embryos were recorded. The correlation between Chinese medical adjuvant therapy and the aforesaid indices were observed. The clinical pregnancy rate and the abortion rate were finally compared between the two groups. The total dose of r-FSH, the E2 level on HCG injection day, the serum E2 level on the oocyte retrieval day, the number of retrieved oocyte, the number of oocytes in M II the number of oocytes with 2PN, the number of portable embryos, and the number of good quality embryos were all positively correlated with Chinese medical adjuvant therapy (P < 0.05, P < 0.01). Compared with the control group, serum E2 levels on the HCG injection day and the oocyte retrieval day obviously increased, the number of retrieved oocytes, the number of oocytes in M II, and the number of portable embryos were increased more in the experimental group with statistical difference (P < 0.05, P < 0.01). There was no statistical significance in the clinical pregnancy rate or the abortion rate between the two groups (P > 0.05). SGRS Chinese herbs as adjuvant therapy could improve ovarian responsiveness of DOR patients undergoing IVF-ET, increase the number of retrieved oocytes, elevate the quality of oocytes and the number of embryos.

What is the influence of vitamin D deficiency on pregnancy rates among women undergoing IVF/ICSI and Day 5 (blastocyst stage) single embryo transfer (SET)? Vitamin D deficiency results in significantly lower pregnancy rates in women undergoing single blastocyst transfer. Preliminary experiments have identified the presence of vitamin D receptors in the female reproductive system. However, results regarding the effect of vitamin D deficiency on clinical outcomes are conflicting. None of the previous studies adopted a SET strategy. Serum vitamin D concentration was measured retrospectively in patients who underwent SET on Day 5. Overall 368 consecutive infertile women treated within a period of 15 months were included in the study. All patients underwent ovarian stimulation for IVF/ICSI and Day 5 SET. Serum samples were obtained 7 days prior to embryo transfer and stored frozen at -20°C. Samples were collectively analyzed for their 25-OH vitamin D content. Vitamin D deficiency was defined as serum 25-OH vitamin D levels <20 ng/ml in accordance with the Institute of Medicine and the Endocrine Society clinical practice guidelines. Clinical pregnancy rates were significantly lower in women with vitamin D deficiency compared with those with higher vitamin D values (41 versus 54%, P = 0.015).Logistic regression analysis was performed to identify whether vitamin D deficiency is independently associated with clinical pregnancy rates after controlling for 16 potential confounding factors. According to our results vitamin D deficiency was independently associated with lower clinical pregnancy rates, odds ratios [ORs (95% confidence interval (CI) 0.61 (0.39-0.95)] for vitamin D deficiency (deficient versus non-deficient women), P = 0.030. Finally, even when restricting our analysis to women undergoing elective SET (274 patients), vitamin D deficiency was again independently associated with pregnancy rates [OR (95% CI) 0.56 (0.33-0.93), P = 0.024]. Our results refer only to patients undergoing Day 5 SET. Although vitamin D deficiency appears to compromise pregnancy rates in this population, no guidance can be provided regarding a potential relationship between vitamin D deficiency and ovarian reserve or response to ovarian stimulation. Vitamin D deficiency impairs pregnancy rates in women undergoing single blastocyst transfer. Future prospective confirmatory studies are needed to validate our results and examine the exact underlying mechanism by which vitamin D levels may impair pregnancy rates in infertile women undergoing IVF/ICSI.

Complete cytoreduction is the most important prognostic factor in ovarian cancer. However, there exist conflicting data on whether the removal of microscopic tumor metastasis in macroscopically unsuspicious retroperitoneal lymph nodes is beneficial. Ovarian cancer tissues and tissues from lymph node metastasis of 30 patients with FIGO IIIC or IV disease undergoing neoadjuvant chemotherapy (NACT) were obtained and assessed using a validated regression score. Histopathological markers, size of largest tumor focus, and overall score were evaluated in lymph node and ovarian tissue. Regression and known prognostic factors were analyzed for influence on survival. No difference in the overall score between lymph nodes and ovarian tissue was shown, however, single parameters such as fibrosis and pattern of tumor infiltration, were significantly different. The pattern of tumor regression in lymph nodes and ovarian tissue are of prognostic value. Lymph node dissection even of unsuspicious nodes should, therefore, be performed.

Premature ovarian failure is a major concern in women of reproductive age who undergo gonadotoxic cancer treatment. Autotransplantation of frozen-thawed cortical ovarian tissue allows the immediate start of cancer treatment, but risks reintroduction of cancer. Current tumor detection methods compromise the ovarian tissue's viability and can therefore only be used to exclude the presence of metastases in the cortical ovarian strips that are not transplanted. A non-invasive method is needed that can be used to exclude metastases in the actual ovarian autografts without affecting the tissue's viability. In this study we applied FFOCT - a non-fixative technique that uses white light interferometry to make highresolution images (1μm isotropic) of fresh tissue - to study healthy and malignant ovarian tissue. We created an image atlas of healthy ovarian tissues from premenopausal patients and ovarian tissues with breast cancer metastases. To get the best possible match between hematoxylin-and-eosin stained slides and FFOCT images formalinfixed paraffin-embedded tissue samples were deparaffinized and FFOCT images were acquired within a few minutes. FFOCT images were compared with histology images. All normal structures such as follicles in all phases, inclusion cysts, blood vessels, corpora lutea, and corpora albicantia were clearly recognizable. Ovarian metastases could be well distinguished from normal ovarian tissue. FFOCT is a promising technique in the field of fertility preservation: metastases can be detected and additionally cortical ovarian strips can be selected on the basis of high follicle density.

Cells of origin of ovarian cancer: ovarian surface epithelium or fallopian tube?

PubMed

Klotz, Daniel Martin; Wimberger, Pauline

2017-12-01

Ovarian cancer is the fifth most common cancer in women and one of the leading causes of death from gynecological malignancies. Despite of its clinical importance, ovarian tumorigenesis is poorly understood and prognosis remains poor. This is particularly true for the most common type of ovarian cancer, high-grade serous ovarian cancer. Two models are considered, whether it arises from the ovarian surface epithelium or from the fallopian tube. The first model is based on (1) the pro-inflammatory environment caused by ovulation events, (2) the expression pattern of ovarian inclusion cysts, and (3) biomarkers that are shared by the ovarian surface epithelium and malignant growth. The model suggesting a non-ovarian origin is based on (1) tubal precursor lesions, (2) genetic evidence of BRCA1/2 mutation carriers, and (3) recent animal studies. Neither model has clearly demonstrated superiority over the other. Therefore, one can speculate that high-grade serous ovarian cancer may arise from two different sites that undergo similar changes. Both tissues are derived from the same embryologic origin, which may explain how progenitor cells from different sites can respond similar to stimuli within the ovaries. However, distinct molecular drivers, such as BRCA deficiency, may still preferentially arise from one site of origin as precancerous mutations are frequently seen in the fallopian tube. Confirming the origin of ovarian cancer has important clinical implications when deciding on cancer risk-reducing prophylactic surgery. It will be important to identify key biomarker to uncover the sequence of ovarian tumorigenesis.

Abstract The effectiveness of thalidomide in treating inflammatory bowel disease (IBD) has been widely recognized. Meanwhile, many serious adverse drug reactions have been observed, but no know reports on ovarian reserve function. Female patients, ranging in age between 18 and 40, were referred to our institution to undergo sex hormone detection and ultrasonic scanning for ovarian function assessment, between February 1, 2016 and September 31, 2016. Thirty-three patients treated with thalidomide (group A), 73 patients without thalidomide (group B), and 78 healthy women as control were studied. Menstrual disorder was higher in group A than group B (78.8% vs 57.2%, P < 0.05), and both groups were higher than control group 33.3%, P < 0.05. Anti-Mullerian hormone (AMH) levels and antral follicle count (AFC) in group A were lower than group B, P < 0.05, while estradiol (E2) and follicle-stimulating hormone (FSH) levels were no different between 2 groups. Crohn Disease Endoscopic Index of Severity (CDEIS) and thalidomide were the independent risk factors in diminished ovarian reserve (DOR), and when dose reached 75 mg/day, 5 g total, or when treatment time reached 10 months respectively. These influence may increasing (P < 0.05), but they may recover after stopping (P < 0.05). Thalidomide was an independent risk factor leading to DOR in female IBD patients, the influence may increasing when daily dose and accumulated dose reached 75 mg/day and 5 g total dose, but may be reversed by stopping.

Endometriosis and Ovarian Cancer: A Review of Clinical, Pathologic, and Molecular Aspects

2014-01-01

Summary Endometriosis is a chronic disease that affects millions of reproductive-age women. Despite the destructive and invasive nature of endometrioses, most cases are perpetually benign or eventually regress; however, atypical endometriosis is a precursor lesion and can lead to certain types of ovarian cancer. Endometriosis induced inflammation and auto- and paracrine production of sex steroid hormones contribute to ovarian tumorigenesis. These changes provide microenvironment necessary to accumulate enough genetic alterations for endometriosis associated malignant transformation. It takes years for endometriosis to undergo the pathophysiological progression that begins with atypical epithelial proliferation (atypical endometriosis and metaplasia), and then is followed by the formation of well-defined borderline tumors, and finally culminates in fully malignant ovarian cancer. This study is a review of the natural history of endometriosis and the role of microenvironments that favor the accumulation of genetic alterations and endometriosis-associated ovarian cancer progression.

Hopelessness negatively affects ovarian cancer patients' quality of life (QOL). Research validating the effects of complementary and alternative medicine (CAM) use on QOL and hope is scarce, even though QOL and hope are reasons that patients cite for using CAM therapy. Clinicians need effective, evidence-based interventions to improve QOL and reduce hopelessness. The objectives of this study were to examine factors influencing hopelessness in patients with newly diagnosed disease, long-term survivors, and patients experiencing ovarian cancer recurrence and to examine the effects of CAM on hopelessness in the same population. Surveys of ovarian cancer patients (N = 219) undergoing treatment at a comprehensive cancer center in the United States were analyzed. Descriptive, correlation, and multivariate analyses described variables and demonstrated the effects of sociodemographics, disease state, psychological distress, QOL, CAM use, and faith on hopelessness. Patients ages 65 years or older (-0.95, P = .03), with strong faith (-0.28, P = .00), and good QOL (0.11, P = .00) directly reduced hopelessness scores (mean, 3.37). Massage therapy substantially reduced hopelessness scores (-1.07, P = .02); holding age constant, employed patients were twice as likely to use massage (odds ratio, 2.09; P = .04). Patients who had newly diagnosed and recurrent ovarian cancer were more hopeless because of greater distress from symptoms and adverse effects of treatment. Patients who used massage therapy were significantly less hopeless, as were those with strong faith and well-controlled disease symptoms and treatment for adverse effects. Support of spiritual needs and symptom management are important interventions to prevent and/or reduce hopelessness, especially for patients with newly diagnosed and recurrent ovarian cancer. Further research testing the positive effect of massage interventions on hopelessness is needed.

Abstract. Ovarian cancer is the most deadly gynecologic cancer, a fact which is attributable to poor early detection and survival once the disease has reached advanced stages. Intraoperative laparoscopic volume holographic imaging has the potential to provide simultaneous visualization of surface and subsurface structures in ovarian tissues for improved assessment of developing ovarian cancer. In this ex vivo ovarian tissue study, we assembled a benchtop volume holographic imaging system (VHIS) to characterize the microarchitecture of 78 normal and 40 abnormal tissue specimens derived from ovarian, fallopian tube, uterine, and peritoneal tissues, collected from 26 patients aged 22 to 73 undergoing bilateral salpingo-oophorectomy, hysterectomy with bilateral salpingo-oophorectomy, or abdominal cytoreductive surgery. All tissues were successfully imaged with the VHIS in both reflectance- and fluorescence-modes revealing morphological features which can be used to distinguish between normal, benign abnormalities, and cancerous tissues. We present the development and successful application of VHIS for imaging human ovarian tissue. Comparison of VHIS images with corresponding histopathology allowed for qualitatively distinguishing microstructural features unique to the studied tissue type and disease state. These results motivate the development of a laparoscopic VHIS for evaluating the surface and subsurface morphological alterations in ovarian cancer pathogenesis. PMID:24676382

To examine temporal trends in treatment and survival among black, Asian, Hispanic, and white women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. Using the National Cancer Database (2004-2014), we identified women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. For each disease site, we analyzed race/ethnicity-specific trends in receipt of evidence-based practices. Professional societies' recommendations were used to define these practices. Using data from the Surveillance, Epidemiology, and End Results Program (2000-2009) we analyzed trends in 5-year survival. Throughout the study period black (64.8%) and Hispanic (68.3%) women were less likely to undergo lymphadenectomy for stage I ovarian cancer compared to Asian (79.5%) and white patients (74.6%). Black women were the least likely group to undergo lymphadenectomy in all periods. Among patients with stage II-IV ovarian cancer, 76.6% of white and Asian women received both surgery and chemotherapy, compared to 70.8% of black and 73.9% Hispanic women. Hispanic women with deeply invasive or high-grade stage I endometrial cancer underwent lymphadenectomy less frequently (74.5%) than all other groups (80.7%). Black women were less likely to have chemo-radiotherapy for stage IIB-IVA cervical cancer (75.6% versus 80.4% of all others). Black women were also less likely to have a surgical lymph node evaluation for vulvar cancer (58.8% versus 63.5% of all others). Among women diagnosed with ovarian, endometrial, and cervical cancer, black women had lower five-year survival than other groups. Significant racial disparities persist in the delivery of evidence-based care. Black women with ovarian, endometrial, and cervical cancer continue to experience higher cancer-specific mortality than other groups. Copyright © 2017 Elsevier Inc. All rights reserved.

Melatonin, the major hormone of the pineal gland, has antigonadotrophic activity in many mammals and may also be involved in human reproduction. Melatonin suppresses steroidogenesis by ovarian granulosa and luteal cells in vitro. To determine if melatonin is present in the human ovary, preovulatory follicular fluids (n = 32) from 15 women were assayed for melatonin by RIA after solvent extraction. The fluids were obtained by laparoscopy or sonographically controlled follicular puncture from infertile women undergoing in vitro fertilization and embryo transfer. All patients had received clomiphene citrate, human menopausal gonadotropin, and hCG to stimulate follicle formation. Blood samples were obtained by venipuncture 30 rain or less after follicular aspiration. All of the follicular fluids contained melatonim, in concentrations substantially higher than those in the corresponding serum. A positive correlation was found between follicular fluid and serum melatonin levels in each woman; these observations indicate that preovulatory follicles contain substantial amounts of melatonin that may affect ovarian steroidogenesis.

Regulation of Ovarian Cancer Stem Cells or Tumor-Initiating Cells

2013-01-01

Cancer stem cells or tumor-initiating cells (CSC/TICs), which can undergo self-renewal and differentiation, are thought to play critical roles in tumorigenesis, therapy resistance, tumor recurrence and metastasis. Tumor recurrence and chemoresistance are major causes of poor survival rates of ovarian cancer patients, which may be due in part to the existence of CSC/TICs. Therefore, elucidating the molecular mechanisms responsible for the ovarian CSC/TICs is required to develop a cure for this malignancy. Recent studies have indicated that the properties of CSC/TICs can be regulated by microRNAs, genes and signaling pathways which also function in normal stem cells. Moreover, emerging evidence suggests that the tumor microenvironments surrounding CSC/TICs are crucial for the maintenance of these cells. Similarly, efforts are now being made to unravel the mechanism involved in the regulation of ovarian CSC/TICs, although much work is still needed. This review considers recent advances in identifying the genes and pathways involved in the regulation of ovarian CSC/TICs. Furthermore, current approaches targeting ovarian CSC/TICs are described. Targeting both CSC/TICs and bulk tumor cells is suggested as a more effective approach to eliminating ovarian tumors. Better understanding of the regulation of ovarian CSC/TICs might facilitate the development of improved therapeutic strategies for recurrent ovarian cancer. PMID:23528891

Ovarian ectopic pregnancies are a rare occurrence; however the incidence is on the rise. Preoperative diagnosis remains difficult due to nonspecific clinical symptoms and USS findings. Most patients undergo diagnostic laparoscopy with subsequent surgical management. We present the case of a 32-year-old female who presented with vaginal bleeding and an unsited pregnancy, with a BhCG of 24693. Formal USS described unruptured right tubal ectopic with ovarian pregnancy being diagnosed at laparoscopy. A wedge resection was conducted to preserve ovarian function. Postoperative recovery was uneventful and BhCG levels returned to zero (nonpregnant) in an outpatient setting. Although laparoscopy remains the gold standard of diagnosis and treatment, in this case report we discuss benefits of early diagnosis for fertility conserving management, including nonsurgical options.

Polycystic ovary syndrome (PCOS) is the most common endocrinological pathology among women of reproductive age, and is characterized by abnormalities in ovarian angiogenesis, among other features. Consistent with this association, follicular fluid (FF) concentration and ovarian expression of vascular endothelial growth factor (VEGF) are increased in PCOS patients. In this study, we examined the protein levels of platelet-derived growth factor (PDGF) BB and DD (PDGFBB and PDGFDD), angiopoietin 1 and 2 (ANGPT1 and ANGPT2), and their soluble receptor sTIE2 in FF from PCOS and control patients undergoing assisted reproductive techniques. We also analyzed the effect of FF from PCOS and control patients on tight and adherens junction protein expression in an endothelial cell line. PDGFBB and PDGFDD were significantly lower whereas ANGPT1 concentration was significantly higher in FF from PCOS patients than from control patients. No changes were found in the concentration of ANGPT2 or sTIE2. Expression of claudin-5 was significantly increased in endothelial cells incubated for 24 hr in the presence of FF from PCOS versus from control patients, while vascular-endothelial cadherin, β-catenin, and zonula occludens 1 expression were unchanged. The changes observed in the levels of PDGF isoforms and ANGPT1 may prevent VEGF-induced vascular permeability in the PCOS ovary by regulating endothelial-cell-junction protein levels. Restoring the levels of angiogenic factors may provide new insights into PCOS treatment and the prevention of ovarian hyperstimulation syndrome in affected women. © 2014 Wiley Periodicals, Inc.

Ovarian tissue cryopreservation is, in most cases, the only fertility preservation option available for female patients soon to undergo gonadotoxic treatment. To date, cryopreservation of ovarian tissue has been carried out by both traditional slow freezing method and vitrification, but even with the best techniques, there is still a considerable loss of follicle viability. In this report, we investigated a stepped cryopreservation procedure which combines features of slow cooling and vitrification (hereafter called stepped vitrification). Bovine ovarian tissue was used as a tissue model. Stepwise increments of the Me 2 SO concentration coupled with stepwise drops-in temperature in a device specifically designed for this purpose and X-ray computed tomography were combined to investigate loading times at each step, by monitoring the attenuation of the radiation proportional to Me 2 SO permeation. Viability analysis was performed in warmed tissues by immunohistochemistry. Although further viability tests should be conducted after transplantation, preliminary results are very promising. Four protocols were explored. Two of them showed a poor permeation of the vitrification solution (P1 and P2). The other two (P3 and P4), with higher permeation, were studied in deeper detail. Out of these two protocols, P4, with a longer permeation time at -40 °C, showed the same histological integrity after warming as fresh controls. Copyright © 2018 Elsevier Inc. All rights reserved.

Temporary ovarian failure in thyroid cancer patients after thyroid remnant ablation with radioactive iodine

DOE Office of Scientific and Technical Information (OSTI.GOV)

Raymond, J.P.; Izembart, M.; Marliac, V.

We studied ovarian function retrospectively in 66 women who had regular menstrual cycles before undergoing complete thyroidectomy for differentiated thyroid cancer and subsequent thyroid remnant ablation with /sup 131/I. Eighteen women developed temporary amenorrhea accompanied by increased serum gonadotropin concentrations during the first year after /sup 131/I therapy. No correlation was found between the radioactive iodine dose absorbed, thyroid uptake before treatment, oral contraceptive use, or thyroid autoimmunity. Only age was a determining factor, with the older women being the most affected. We conclude that radioiodine ablation therapy is followed by transient ovarian failure, especially in older women.

To review the clinical aspects of ovarian hyperstimulation syndrome and provide recommendations on its prevention. Preventative measures, early recognition, and prompt systematic supportive care will help avoid poor outcomes. Establish guidelines to assist in the prevention of ovarian hyperstimulation syndrome, early recognition of the condition when it occurs, and provision of appropriate supportive measures in the correct setting. Published literature was retrieved through searches of Medline, Embase, and the Cochrane Library from 2011 to 2013 using appropriate controlled vocabulary ([OHSS] ovarian hyperstimulation syndrome and: agonist IVF, antagonist IVF, metformin, HCG, gonadotropin, coasting, freeze all, agonist trigger, progesterone) and key words (ovarian hyperstimulation syndrome, ovarian stimulation, gonadotropin, human chorionic gonadotropin, prevention). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English. There were no date restrictions. Searches were updated on a regular basis and incorporated in the guideline to February 2013. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). Summary Statements 1. The particular follicle-stimulating hormone formulation used for ovarian stimulation does not affect the incidence of ovarian hyperstimulation syndrome. (I) 2. Coasting may reduce the incidence of severe ovarian hyperstimulation syndrome. (III) 3. Coasting for longer than 3 days reduces in vitro fertilization pregnancy rates. (II-2) 4. The use of either luteinizing hormone or human chorionic gonadotropin for final oocyte maturation does not influence the incidence of ovarian hyperstimulation syndrome. (I) 5. There is no clear published evidence that lowering the human chorionic gonadotropin dose will result in a decrease in the rate of ovarian hyperstimulation syndrome. (III) 6. Cabergoline starting from the day of human chorionic gonadotropin reduces the incidence of ovarian hyperstimulation syndrome in patients at higher risk and does not appear to lower in vitro fertilization pregnancy rates. (II-2) 7. Avoiding pregnancy by freezing all embryos will prevent severe prolonged ovarian hyperstimulation syndrome in patients at high risk. (II-2) 8. Pregnancy rates are not affected when using gonadotropin-releasing hormone (GnRH) agonists in GnRH antagonist protocols for final egg maturation when embryos are frozen by vitrification for later transfer. (II-2) Recommendations 1. The addition of metformin should be considered in patients with polycystic ovarian syndrome who are undergoing in vitro fertilization because it may reduce the incidence of ovarian hyperstimulation syndrome. (I-A) 2. Gonadotropin dosing should be carefully individualized, taking into account the patient's age, body mass, antral follicle count, and previous response to gonadotropins. (II-3B) 3. Cycle cancellation before administration of human chorionic gonadatropin is an effective strategy for the prevention of ovarian hyperstimulation syndrome, but the emotional and financial burden it imposes on patients should be considered before the cycle is cancelled. (III-C) 4. Gonadotropin-releasing hormone (GnRH) antagonist stimulation protocols are recommended in patients at high risk for ovarian hyperstimulation syndrome (OHSS). The risk of severe OHSS in patients on GnRH antagonist protocols who have a very robust ovarian stimulation response can be reduced by using a GnRH agonist as a substitute for human chorionic gonadotropin to trigger final oocyte maturation. (I-B) 5. A gonadotropin-releasing hormone (GnRH) antagonist protocol with a GnRH agonist trigger for final oocyte maturation is recommended for donor oocyte and fertility preservation cycles. (III-C) 6. Albumin or other plasma expanders at the time of egg retrieval are not recommended for the prevention of ovarian hyperstimulation syndrome. (I-E) 7. Elective single embryo transfer is recommended in patients at high risk for ovarian hyperstimulation syndrome. (III-C) 8. Progesterone, rather than human chorionic gonadotropin, should be used for luteal phase support. (I-A) 9. Outpatient culdocentesis should be considered for the prevention of disease progression in severe ovarian hyperstimulation syndrome. (II-2B).

Ovarian response markers lead to appropriate and effective use of corifollitropin alpha in assisted reproduction.

PubMed

La Marca, Antonio; D'Ippolito, Giovanni

2014-02-01

Corifollitropin alpha is a highly effective gonadotrophin, which maintains multifollicular growth for a week. The advantages of its administration include ease of use of the drug, making the treatment more patient friendly, resulting in a lower level of distress for the patient. At the same time, the pregnancy rate resulting from its use in IVF/intracytoplasmic sperm injection cycles is similar to that found when daily recombinant FSH is administered. The ovarian response to corifollitropin alpha is dependent on clinically established predictors such as baseline FSH, antral follicle count (AFC) and age. There is a general trend towards a higher ovarian response with an increasing AFC and the number of oocytes per attempt decreased with increasing baseline FSH and age. Even if the risk of ovarian hyperstimulation syndrome following corifollitropin alpha is very similar to the rate reported in literature for young women undergoing IVF, the risk of overstimulation may be reduced by avoiding maximal ovarian stimulation in women anticipated to be hyperresponders. High basal anti-Müllerian hormone and/or AFC can identify women with enhanced functional ovarian reserve at risk of overstimulation, and the risk is even higher if maximally stimulated with corifollitropin alpha or high dose of daily recombinant FSH. Corifollitropin alpha is a highly effective gonadotrophin which maintains multifollicular growth for a week. The ovarian response to corifollitropin was demonstrated to be dependent on clinically established predictors such as baseline FSH, antral follicle count (AFC) and age. There was a general trend toward a higher ovarian response with an increasing AFC and the mean number of oocytes per attempt decreased with increasing baseline FSH and age. Even if the risk of ovarian hyperstimulation syndrome (OHSS) following corifollitropin alpha is very similar to the rate of OHSS reported in literature for young women undergoing IVF, the risk of overstimulation may be reduced by avoiding maximal ovarian stimulation in women anticipated to be hyperresponders. Increasing evidence demonstrates that anti-Müllerian hormone and AFC exhibit a very good diagnostic performance in the prediction of hyperresponse. High basal anti-Müllerian hormone and/or AFC can identify women with enhanced functional ovarian reserve who are at risk of overstimulation if stimulated in IVF cycles and the risk is even higher if maximally stimulated with corifollitropin alpha or high dose of daily recombinant FSH.

Best practices for controlled ovarian stimulation in IVF

Jungheim, Emily S.; Meyer, Melissa; Broughton, Darcy E.

2015-01-01

As applications for IVF have expanded over the years, so too have approaches to controlled ovarian stimulation (COS) for IVF. With this expansion and improved knowledge of basic reproductive biology, there is increasing interest in how COS practice influences IVF outcomes, and whether or not specific treatment scenarios call for personalized approaches to COS. For the majority of women undergoing COS and their treating physicians, the goal is to achieve a healthy live birth through IVF in a fresh cycle. Opinions on how COS strategy best leads to this common goal varies among centers as many clinicians base COS strategy not on evidence obtained through prospective randomized trials, but rather through observational studies and experience. Overall, when it comes to COS most clinicians recognize the approach should not be “one size fits all”, but rather a patient-centered approach that takes the existing evidence into consideration. The pages that follow outline the existing evidence for best practices in COS for IVF highlighting how these practices may be incorporated into a patient-centered approach. PMID:25734345

Knowledge and expectations of women undergoing cancer genetic risk assessment: a qualitative analysis of free-text questionnaire comments.

Individuals undergoing cancer genetic risk assessment have been found to have a poor understanding of the process, which may affect how well they cope with learning their risk. This paper reports free-text data from questionnaires completed by women undergoing a randomised controlled trial of a psychological intervention. Of the 268 women undergoing genetic assessment for familial breast/ovarian cancer risk who were invited to take part in the trial, 157 women returned research questionnaires. Of these, 97 women provided free-text comments upon referral to a cancer genetics clinic, 62 provided comments whilst waiting for risk information (average, moderate or high), and 36 women provided comments following notification of risk. This paper reports a thematic analysis of the free-text data. Themes reflected individuals' poor knowledge and uncertainty about genetic risk assessment. How well individuals responded to learning their risk depended upon whether expectations had been met. Regardless of risk, individuals undergoing cancer genetic risk assessment are likely to benefit from increased information about its process and timescales, and access to increased psychological support. Free-text comments can provide valuable data about individuals' expectations and knowledge of genetics services.

Role of Fallopian Tubes in the Development of Ovarian Cancer.

Ovarian cancer is the leading cause of death from gynecologic malignancy and the fifth cause of cancer death in women in the United States. The most common and lethal histologic subtype of epithelial ovarian cancer is high-grade serous carcinoma (HGSC), which generally presents at an advanced stage. HGSC may be associated with BRCA1 and BRCA2 mutations. Historically, HGSC was believed to originate from the ovarian epithelial cells. However, more recent evidence supports the idea that most ovarian cancers originate in the fallopian tube epithelium in both high-risk women and in the general population. Serous tubal intraepithelial carcinomas may ultimately evolve into ovarian or peritoneal cancer. As a result, prophylactic salpingectomy with conservation of the ovaries has become an increasingly more common practice for premenopausal women undergoing risk-reducing surgery. Because the fallopian tube is now recognized as the most common potential site of origin of ovarian carcinoma, there is ongoing research to explore molecular and genetic factors that may be critical in the development of this disease. Further research is needed to identify novel opportunities for early detection and screening of ovarian cancer with the ultimate goal of increasing overall survival. Copyright © 2016 AAGL.

2007-10-01

In this study, we present a case of laparoscopic ovarian transposition to preserve ovarian function in an adult female patient treated with craniospinal irradiation for standard risk medulloblastoma. The prescribed dose to the craniospinal axis was 2340 cGy at 180 cGy per fraction and was delivered with 6-MV photons. Before ovarian transposition, magnetic resonance imaging (MRI) of the pelvis was obtained for localization of the ovaries and was registered with the planning computed tomography (CT) scan. Surgical clips allowed for CT localization of the ovaries after transposition. As a result of ovarian transposition, mean and maximum radiation doses decreased frommore » 983 to 68 cGy and 1624 to 84 cGy for the left ovary and from 166 to 87 cGy and 723 to 103 cGy for the right ovary, respectively. Review of the literature indicates that such radiation doses are below the threshold that causes ovarian dysfunction and infertility. We conclude that ovarian localization with an MRI of the pelvis can be offered to females undergoing craniospinal irradiation. Transposition of the ovaries provides an option to preserve ovarian function in cases where the ovaries would otherwise be included within the radiation field.« less

Except for histological study, there are currently no suitable techniques available for the detection and identification of primordial follicles in ovary of primary ovarian insufficiency patients who have undetectable AMH levels. Also, the ability to locate and quantify follicles on ovarian cortex strips, without fixation, is valuable for patients who could undergo subsequent successful ovarian tissue transplantation. Although optical coherence tomography (OCT) is a well-established high resolution imaging technique without fixation commonly applied in biomedicine, few reports are available on ovarian tissue imaging. In present study, we established standard OCT follicle images at each developmental stage, including the primordial follicle, and demonstrated the efficacy of OCT to estimate IVF outcome in transplanted mice ovary like ovarian reserve tests. Unfortunately, the current commercial OCT could not be used to accurate follicle count the number of follicles for whole ovary, because the maximum depth of examination was 100 μm. And we demonstrated the safety of OCT examination, it did not affect IVF outcome and birth defect rate, and reproductive ability. Although there is room for improvement, these findings will be first step to bring OCT examination a step closer to clinical application for measuring true ovarian reserve and localizing follicles.

To compare the outcome of using gonadotropin-releasing hormone (GnRH) antagonists versus agonists in women with polycystic ovary disease (PCOD) who underwent controlled ovarian hyperstimulation (COH) for assisted reproductive techniques (ART). A total of 129 patients with PCOD were randomly allocated to undergo COH with a GnRH antagonist (59 patients) and GnRH agonist (leuprolide acetate) (70 patients) to prevent a premature luteinizing hormone (LH) surge. Assisted fertilization following oocyte retrieval and embryo transfer was performed. None of the cycles were cancelled due to a premature LH surge. There was no significant difference between the antagonist and agonist arms in the number of gonadotropin ampules consumed per cycle. However, in the antagonist arm a shorter duration of ovarian stimulation was recorded as compared to the agonist arm. Although similar numbers of oocytes was retrieved from both groups of patients, the quality of the oocytes, as measured by metaphase 2/total oocyte ratio, was lower in the antagonist arm as compared to the agonist arm. Pregnancy rates were 57.6% and 58.5% in the antagonist and agonist arms, respectively (p > 0.05). Implantation rates were not different (34.0% and 34.6%, respectively). The frequency of ovarian hyperstimulation syndrome also did not differ between the treatment groups (5% and 7.1%, respectively). The size of our study, on a specific subgroup of patients, does not allow a reliable conclusion regarding ART outcomefollowing the use of a GnRH antagonist versus agonist. Nevertheless, the protocol with the antagonist gave results that were as good as those of the protocol with the agonist in this PCOD patient population.

Thirty-day unplanned hospital readmission in ovarian cancer patients undergoing primary or interval cytoreductive surgery: systematic literature review.

Thirty-day readmission rate has been proposed as metric of quality and remains an ongoing clinical concern in the primary treatment of patients with advanced-stage ovarian epithelial ovarian cancer. We conducted a review of the literature to identify rates, risk factors, and predictors for 30-day readmission in this population. A 10-year period MEDLINE (PubMed) search of English literature studies published between January 01, 2008-January 01, 2018 was performed to identify appropriate studies for review. Thirty -day readmission rates for ovarian cancer patients undergoing primary treatment ranged from 2.5-19.3%. Neoadjuvant chemotherapy and interval cytoreductive surgery (NACT-ICS) surgery was associated with lower readmission rates, when compared to primary debulking surgery (PDS). The most frequently reported adverse events resulting in readmission include inpatient management of ileus/small bowel obstruction, wound-related complications, and thromboembolic events. Readmission predictors included the presence of other medical comorbidities, re-operation, and major complications occurring after initial hospital discharge. Some studies reported lower rates of readmission and survival in patients treated by NACT-ICS. Policies and programs should be designed to measure short- and long-term outcomes in this patient population to avoid bias in assigning patients to NACT-ICS to maintain low 30-day readmission rates.

Analysis of perioperative outcomes and survival of patients with recurrent ovarian cancer undergoing secondary cytoreduction by robotics, laparoscopy, or laparotomy. Retrospective analysis of 52 selected patients with recurrent ovarian cancer undergoing secondary cytoreduction by laparoscopy (9), laparotomy (33) or robotics (10) between January 2006 and December 2010. Comparison was made by a total of 21 factors including age, BMI, number of previous surgeries, tumor type and grade, number of procedures, and 15 types of procedures performed at secondary cytoreduction. For all patients, the mean operating time was 213.8 min, mean blood loss 657.4 ml; and mean hospital stay 7.5 days. Complete debulking was achieved in 75% of patients. Postoperative complications were noted in 36.5% of patients. Overall and progression-free survival at 3-years were 58.8% and 34.1%, respectively. Laparoscopy and robotics had reduced blood loss and hospital stay, while no differences were observed among the three groups for operating time, complications, complete debulking, and survival. Selected patients with recurrent ovarian cancer benefit from a laparoscopic or robotic secondary cytoreduction without compromising survival. Robotics and laparoscopy provide similar perioperative outcomes, and reduced blood loss and shorter hospital stay as compared to laparotomy. Laparotomy seems preferable for patients with widespread peritoneal implants, multiple sites of recurrence, and/or extensive adhesions. Copyright © 2013 Elsevier Inc. All rights reserved.

Conditionally immortal ovarian cell lines for investigating the influence of ovarian stroma on the estrogen sensitivity and tumorigenicity of ovarian surface epithelial cells.

The tendency of the ovarian surface epithelium (OSE) to undergo metaplastic and morphogenetic changes during the life cycle, at variance with the adjacent peritoneal mesothelial cells, suggests that its biology may be regulated by underlying ovarian stromal cues. However, little is known about the role that the ovarian stroma plays in the pathobiology of the OSE, largely because of the lack of a suitable in vitro model. Here, we describe the establishment and characterization of conditionally immortalized ovarian stromal and surface epithelial cell lines from H-2K(b)-tsA58 transgenic mice that carry the thermolabile mutant of SV-40 large T antigen under the control of an interferon-gamma (IFN-gamma)-inducible promoter. These cells express functional T antigens, grow continuously under permissive conditions at 33 degrees C in the presence of IFN-gamma, and stop dividing when the activity and expression of the tumor antigen is suppressed by restrictive conditions without IFN-gamma at 39 degrees C. Morphological, immunohistochemical, and ultrastructural analyses show that conditionally immortal OSE cells form cobblestone-like monolayers, express cytokeratin and vimentin, contain several microvilli, and develop tight junctions, whereas stromal cells are spindle-like, express vimentin but not cytokeratin, and contain rare microvilli, thus exhibiting epithelial and stromal phenotypes, respectively. At variance with the reported behavior of rat epithelial cells, conditionally immortal mouse epithelial cells are not spontaneously transformed after continuous culture in vitro. More importantly, conditioned media from stromal cells cultured under permissive conditions increase the specific activity of the endogenous estrogen receptor in BG-1 human ovarian epithelial cancer cells and promote these cells' anchorage-independent growth, suggesting the paracrine influence of a stromal factor. In addition, stromal cells cultured under restrictive conditions retain this growth-stimulatory activity, which, therefore, appears to be independent of T antigen expression. These established cell lines should provide a useful in vitro model system for studying the role of cellular interactions in OSE cell growth and tumorigenesis.

To assess whether endometrial injury in the cycle preceding controlled ovarian hyperstimulation during intracytoplasmic sperm injection (ICSI) improves the implantation and pregnancy rates. Between January 1, 2016, and March 31, 2017, a randomized controlled trial was conducted at a center in Egypt among 300 women who met inclusion criteria (first ICSI cycle, aged <40 years, day-3 follicle-stimulating hormone <10 IU/L, normal serum prolactin, no uterine cavity abnormality). The women were randomly allocated using a web-based system to undergo endometrial scratch in the cycle preceding controlled ovarian hyperstimulation (n=150) or to a control group (n=150). Only data analysts were masked to group assignment. The primary outcomes were the implantation and clinical pregnancy rates at 14 days and 4 weeks after embryo transfer, respectively. Analyses were by intention to treat. The implantation rate was significantly higher in the endometrial scratch group (41.3% [90/218]) than in the control group (30.0% [63/210]; P<0.001). The clinical pregnancy rate was also significantly higher in the endometrial scratch group (44.2% [61/138]) than in the control group (30.4% [41/135]; P<0.001). Endometrial injury in the cycle preceding the stimulation cycle improved implantation and pregnancy rates during ICSI.

To describe the technique and short-term post-operative outcomes associated with diaphragm full-thickness resection (FTR) and intraoperative trans-diaphragmatic decompression of the resultant pneumothorax (TDDP). All patients undergoing cytoreductive surgery for primary or recurrent ovarian cancer between 8/1/98 and 7/30/09 were retrospectively identified from the tumor registry database. Patients undergoing diaphragm FTR were selected for detailed review of the operative technique and post-operative outcomes. The operative technique of TDDP using a fenestrated Robinson catheter is described. A total of 45 patients met study inclusion criteria. Diaphragm FTR surgery was performed exclusively by gynecologic oncologists in 73.3% of cases. The median patient age was 60 years, and the majority (75.6%) of cases were performed for primary cytoreduction of Stage IIIC (n=27) or Stage IV (n=18) disease. The two-dimensional surface area of tumor involvement ranged from 9 cm(2) to 192 cm(2). The right hemi-diaphragm alone was involved in 71.1% of cases, while both the right and left hemi-diaphragms were involved in 24.4%. TDDP was performed in 41 of the 45 patients undergoing diaphragm FTR, while 4 patients had intraoperative thoracostomy tubes placed. Among the 41 TDDP patients, post-operative days 3-4 radiographic imaging revealed that 56% had a small residual pleural effusion and 9.8% had a residual pneumothorax; however, only 2 patients (4.9%) required post-operative thoracostomy tube placement or thoracentesis. The technique of TDDP eliminates the need of intraoperative and post-operative thoracostomy tube/thoracentesis in 95.1% of patients undergoing diaphragm FTR as a component of ovarian cancer cytoreductive surgery.

The activity of free radicals in follicular fluid was related to ovarian responsiveness, in vitro fertilization (IVF), and embryo transfer success rate. However, studies analyzing the relationship between the free radical scavenging capacity and embryo quality of infertile women with polycystic ovarian syndrome (PCOS) were lacking. The aim of this study was to evaluate the relationship between the free radical scavenging window of women with PCOS and their embryo quality. The free radical scavenging capacity of follicular fluid from women with PCOS was determined by a,a-diphenyl-b-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay, superoxide radical, and reactive oxygen species (ROS) assay. In the DPPH and ROS assays, the follicular fluid from grades I and II embryos was significantly higher than the follicular fluid from grades III and IVembryos. The lower control limit of DPPH radical scavenging capacity and upper control limit of ROS level were 13.2% and 109.0 cps, respectively. The calculated lower control limit and upper control limit were further confirmed in the follicular fluid of embryos of all grades. These cut-off values of free radical scavenging activity of follicular fluid could assist embryologists in choosing the development of embryos in PCOS patients undergoing IVF.

The purpose of this study was to explore the decision-making influences, perceived level of control over decision-making, and mood states of parents and patients who were offered OTC prior to gonadotoxic therapy. Parents and patients, at least 12 years old, who required gonadotoxic therapy and were offered OTC prior to therapy, were asked to complete questionnaires. Two validated instruments were also used: the Decision-Making Control Instrument (DMCI) and the Profile of Mood States (POMS). The factors that influenced decision-making were compared using Student's t test, and the scores of DMCI and POMS were compared using the Mann-Whitney test. Thirty-six parents and 16 patients who elected ovarian tissue cryopreservation (OTC) completed questionnaires. Five parents who declined OTC also completed questionnaires. Accepters thought OTC was a good idea and that, in the future, science would enable cryopreserved ovarian tissue to be used to restore fertility (100% parents, 93.8% patients). Among accepters, the desire for genetically related children and prevention of the stress of infertility drove parents' and patients' decisions (90.9 and 100%, respectively). The desire to prevent the stress of infertility was important to parents, but patients were less likely to report that a desire to prevent the stress of infertility factored into their decision-making (66.7 vs. 50.0%; p < 0.001). All respondents felt in control of their decision and displayed low levels of mood disturbance. Though the decision to undergo experimental OTC is difficult and often urgent, this study suggests that families feel in control of their decision-making and report little emotional disturbance.

Objective: To evaluate the efficacy of preemptive intravenous oxycodone in the patients undergoing laparoscopic resection of ovarian tumor. Methods: Sixty ASA I or II patients undergoing elective laparoscopic resection of ovarian tumor were randomly allocated to one of two groups: Group O (n=30) received intravenous oxycodone (0.1 mg·kg-1) 10 minutes before surgery over 2 minutes, and Group N (n=30) received an equivalent volume of normal saline. All patients received a standardized general anesthesia. MBP and HR at the time of arrival of the operating room (T1), 5 min before pneumoperitoneum (T2), 5 minutes (T3), 10 minutes (T4), and 15 minutes after pneumoperitoneum (T5), and VAS scores at postoperative 2, 4, 8, 12 and 24 hour were recorded. The tramadol consumption and side effects in 24 h after surgery were recorded. Results: VAS pain scores at 2, 4, 8 and 12 hour after operation were significantly lower in Group O (P<0.05). MBP and HR increased significantly due to pneumoperitoneum at T3, T4 and T5, compared with T1 and T2 within Group N, and were higher at T3, T4 and T5 in Group N than at the same time points in Group O. Tramadol consumption was statistically lower in Group O (P=0.0003). Conclusions: Preemptive intravenous oxycodone was an efficient and safe method to reduce intraoperative haemodynamic effect and postoperative pain. PMID:26101479

This study was designed to evaluate follicular survival and growth after short-term transplantation of fresh isolated human follicles and ovarian cortical tissue to nude mice. Ovarian biopsies were obtained from nine women undergoing laparoscopy. Twelve nude mice were xenografted with an ovarian cortical fragment in the right ovarian bursa, and a clot containing isolated follicles in the left, for a period of 7 days. One ungrafted fragment was used as a control. Histological sections were analyzed to determine follicle number and stage. The proliferative status of follicular cells was assessed by Ki-67 immunostaining. A total of 659 follicles was analyzed by histology and 545 follicles by immunohistochemistry. The percentage of primordial follicles was found to be markedly reduced 1 week post-grafting when compared with ungrafted tissue, while the percentage of primary follicles had significantly increased. Only 8% of follicles showed Ki-67-positive granulosa cells before grafting, whereas 1 week after grafting, 71% of follicles in fragments and 67% of isolated follicles were Ki-67-positive (P<0.001). Moreover, the histological aspect of isolated follicle grafts was similar to that of grafted fragments: follicles were surrounded by vimentin-positive stroma-like tissue of human origin, as confirmed by fluorescent in situ hybridization with human-specific probes. Our results demonstrate, for the first time, that isolated human follicles are able to survive and grow after xenografting. This study also shows massive in vivo follicular activation after transplantation of grafted fragments and isolated follicles. One week after grafting, well-structured stroma-like tissue of human origin was observed around the isolated follicles. The potential origin of this stroma is discussed.

To evaluate the relationship between genetic ethnicity using ancestry informative markers (AIMs) and ovarian reserve and response parameters as evidenced by FSH, antimüllerian hormone (AMH), basal antral follicle count (BAFC), and total oocyte yield in IVF. Retrospective. Academic medical center. A total of 2,508 infertile patients undergoing IVF at a single center. Patients were genotyped for 32 AIMs and analyzed for differences in allele frequencies. A validated Bayesian clustering algorithm was then used to assign individuals into one of four ethnic populations: European, African, Central/South Asian, or East Asian. FSH, AMH, BAFC, and oocyte yield variation. After controlling for age and body mass index, genetic ethnicity had no impact on AMH, BAFC, and oocyte yield. FSH was found to be lower in patients of Central/South Asian ancestry (6.46 ng/mL vs. 6.97 ng/mL); however, the absolute difference is of little clinical significance. Subgroup analyses of 1,327 patients restricted to those with limited genetic admixture as determined by AIMs indicated that FSH, AMH, BAFC, and oocyte yield were equivalent. When determining ethnicity using AIMs, ethnic background does not have an impact on markers of ovarian reserve or ovarian response. Specifically, no differences were found in AMH, BAFC, or oocyte yield relative to genotypic ethnicity. Using AIMs rather than self-reported ethnicity allows for elimination of reporting biases and nonreporting of ethnicity, which can confound data. Based upon these data, specific recommendations for ovarian reserve testing should thus be made based on other factors besides ethnic background.

To establish the feasibility and acceptability of completing a higher dose of the planned physical activity volume among women with ovarian cancer, including those undergoing active treatment. 
. A pre-/post-test exercise intervention. All participants were asked to complete 225 minutes per week of physical activity for 26 weeks. Multiple supports were provided, including exercise DVDs, self-reported logs, and an objective physical activity tracker (Fitbit®).
. Home-based exercise intervention with in-person training and telephone follow-ups.
. 10 women with ovarian cancer who were treated within Penn Medicine in Philadelphia, Pennsylvania.
. Home-based, in-person exercise counseling was provided by an exercise trainer weekly for the first six weeks and then monthly for a total of 26 weeks. Weekly follow-up telephone calls were used to assess exercise adherence and barriers to completing exercise, review symptom changes, and provide behavioral support. 
. Feasibility and acceptability.
. Eight participants completed the study and achieved at least 80% of the prescribed exercise dose. Five participants were undergoing chemotherapy simultaneously. Participants experienced no adverse events during the 26-week intervention. Compared to baseline, average steps increased by 1,593 per day and moderate-intensity physical activity increased by 15 minutes per day. 
. A 225-minutes-per-week exercise program is feasible and acceptable in a population of patients with ovarian cancer. Participants significantly improved their physical activity during the 26-week intervention.
. The findings suggest that nursing professionals could recommend that women with ovarian cancer exercise 225 minutes per week regardless of cancer and/or treatment trajectory. For those experiencing aches and pains, behavioral supports and suggestions of a lower exercise dose are needed to maintain physical activity.

Background: Microdose flare-up GnRH agonist and GnRH antagonist have become more popular in the management of poor ovarian responders (POR) in recent years; however, the optimal protocol for POR patients undergoing in vitro fertilization has still been a challenge. Methods: In this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for their response to GnRH agonist protocol (group-1, n=135) or GnRH antagonist protocol (group-2, n=109). Clinical pregnancy rate was the primary end point and was compared between the groups. Student t-test, Mann Whitney U test and χ2-test were used to compare the groups. The p<0.05 was considered to show a statistically significant result. Results: The mean total gonadotropin doses were 3814±891 IU in group 1 and 3539±877 IU in group 2 (p=0.02). The number of metaphase-II oocytes (3.6±2.4 vs. 2.8±1.9, p=0.005) and implantation rates (27.8% vs. 18.8%, p=0.04) in group 1 and group 2, respectively were significantly different. The fertilization rate in group 1 and group 2 was 73% vs. 68%, respectively (p=0.5) and clinical pregnancy rate was 19.8% vs. 14.4%, respectively (p=0.13). Conclusion: The GnRH agonist microdose flare-up protocol has favorable outcomes with respect to the number of oocytes retrieved and implantation rate; nevertheless, the clinical pregnancy rate was found to be similar in comparison to GnRH antagonist protocol in poor ovarian responders. GnRH antagonist protocol appears to be promising with significantly lower gonadotropin requirement and lower treatment cost in poor ovarian responders. PMID:27478770

To study the preservation of follicles within ovarian tissue vitrified using only one or a combination of three permeating cryoprotectants. Experimental study. University hospital. Ovarian tissue was donated by consenting women undergoing elective cesarean section. Ovarian tissue was vitrified in closed sealed vials using either a combination of dimethyl sulfoxide, 1,2-propanediol, and ethylene glycol (EG), or only EG as permeating cryoprotectants. Ovarian tissue was vitrified with the use of two vitrification methods. Tissue from the same donor was used for comparison of two different solutions. The morphology of the follicles was evaluated after vitrification, warming, and culture by light microscopy and transmission electron microscopy. Apoptosis was assessed by immunohistochemistry for active caspase-3 in fresh and vitrified tissue. Light and electron microscopic analysis showed equally well preserved morphology of oocytes, granulosa cells, and ovarian stroma when either of the vitrification solutions was used. No apoptosis was observed in primordial and primary follicles. Using only EG as a permeating cryoprotectant in a closed tube gives as good ultrastructural preservation of ovarian follicles as a more complicated system using several cryoprotectants.

Epithelial ovarian cancer is a highly fatal gynecologic malignancy with a poor prognosis. Therefore, identification of new modifiable prognostic factors is important. Due to the fact that the effect of body weight changes during chemotherapy for EOC is still not very well known we aimed to describe, considering evidence, role of body weight changes in relation to survival. Between October 2014 and August 2015 we systematically searched the following databases: Medline, Scopus, Web of Science and EMBASE to identify the studies describing the influence of body weight changes on survival in patients undergoing chemotherapy for EOC. We identified 601 potentially relevant publications, however finally only one article was included for data extraction and analysis. The overall survival in the selected paper was significantly associated with body weight changes during the first-line chemotherapy. Nevertheless, no influence on progression free survival was found. The analyzed data provides initial evidence, showing poorer overall survival  associated with body weight loss and improved overall survival associated with body weight gain during primary chemotherapy for epithelial ovarian cancer. Prospective and retrospective trials are an urgent calling to confirm this conclusion.

To demonstrate the efficiency of vitrifying mature human oocytes for different clinical indications. Descriptive case series. Cryobiology laboratory, Centro Colombiano de Fertilidad y Esterilidad-CECOLFES LTDA. (Bogotá, Colombia). Oocyte vitrification was offered as an alternative management for patients undergoing infertility treatment because of ovarian hyperstimulation syndrome, premature ovarian failure, natural ovarian failure, male factor, poor response, or oocyte donation. Mature oocytes were obtained from 33 donor women and 40 patients undergoing infertility treatment. Oocytes were retrieved by ultrasound-guided transvaginal aspiration and vitrified with the Cryotops method, with 30% ethylene glycol, 30% dimethyl sulfoxide, and 0.5 mol/L sucrose. Viability was assessed 3 hours after thawing. The surviving oocytes were inseminated by intracytoplasmic sperm injection. Fertilization was evaluated after 24 hours. The zygotes were further cultured in vitro for up to 72 hours until time of embryo transfer. Recovery, viability, fertilization, and pregnancy rates. Oocyte vitrification with the Cryotop method resulted in high rates of recovery, viability, fertilization, cleavage, and ongoing pregnancy. Vitrification with the Cryotop method is an efficient, fast, and economical method for oocyte cryopreservation that offers high rates of survival, fertilization, embryo development, and ongoing normal pregnancies, providing a new alternative for the management of female infertility.

To evaluate whether opportunistic salpingectomy in premenopausal women undergoing hysterectomy for benign indications is both hormonally and surgically safe, compared with hysterectomy without salpingectomy. In this multicentre randomised controlled trial, women were randomised to undergo either hysterectomy with opportunistic bilateral salpingectomy (intervention group) or standard hysterectomy with preservation of the Fallopian tubes (control group). The primary outcome was the difference in serum anti-Müllerian hormone concentration (ΔAMH), measured pre-surgery and 6 months post-surgery. Secondary outcomes were surgical outcomes and duration of hospital stay. The sample size was powered at 50 participants per group (n=100) to compare ΔAMH after hysterectomy with salpingectomy to ΔAMH after standard hysterectomy. Between March 2013 and December 2016, 104 women, aged 30-55 years, were randomly allocated to hysterectomy with opportunistic bilateral salpingectomy (n=52) or standard hysterectomy (n=52). The baseline characteristics did not differ between the two groups. The median ΔAMH was -0.14pmol/L (IQR -1.47-0.95) in the intervention group and 0.00pmol/L (IQR -1.05-0.80) in the control group (p=0.49). The addition of salpingectomy did not impair surgical results and it did not affect duration of hospital stay. Addition of opportunistic bilateral salpingectomy during hysterectomy did not result in a larger effect on ovarian reserve when compared with hysterectomy alone, neither did it affect surgical outcomes. Therefore, opportunistic salpingectomy seems to be a safe procedure in premenopausal women undergoing hysterectomy for benign gynaecological conditions. Copyright © 2017 Elsevier B.V.

To elucidate the impact of ovarian stimulation on the intrauterine milieu represented by the cytokine, chemokine, and growth factor profile in endometrial secretions aspirated before embryo transfer. Prospective cohort study. Fertility center in tertiary referral university hospital. Forty-two patients undergoing ovarian stimulation with GnRH analogues were recruited. They participated in both a natural and an ovarian-stimulated cycle for within patient comparisons. Endometrial secretion aspiration was performed immediately before embryo transfer. The concentrations of 17 mediators known to be involved in human embryo implantation were assessed by multiplex immunoassay. After correction for multiple testing, significantly higher concentrations of interleukin (IL)-1β, IL-5, IL-10, IL-12, IL-17, tumor necrosis factor (TNF)-α, heparin-binding epidermal growth factor (HbEGF), eotaxin, and dickkopf homologue-1 were present in endometrial secretions obtained in stimulated compared with natural cycles. Endometrial secretion analysis provides a novel means of investigating the effect of ovarian stimulation on the intrauterine milieu. The in vivo milieu encountered by the embryo after transfer is significantly altered by ovarian stimulation. Copyright © 2010 American Society for Reproductive Medicine. Published by Elsevier Inc.

2017-07-01

In vitro culture of ovarian follicles isolated or enclosed in ovarian tissue fragments and grafting of isolated ovarian follicles represent a potential alternative to restore fertility in cancer patients who cannot undergo cryopreservation of embryos or oocytes or transplantation of frozen-thawed ovarian tissue. In this regard, respecting the three-dimensional (3D) architecture of isolated follicles is crucial to maintaining their proper follicular physiology. To this end, alginate hydrogel has been widely investigated using follicles from numerous animal species, yielding promising results. The goal of this review is therefore to provide an overview of alginate applications utilizing the biomaterial as a scaffold for 3D encapsulation of isolated ovarian follicles. Different methods of isolated follicle encapsulation in alginate are discussed in this review, as its use of 3D alginate culture systems as a tool for in vitro follicle analysis. Possible improvements of this matrix, namely modification with arginine-glycine-aspartic acid peptide or combination with fibrin, are also summarized. Encouraging results have been obtained in different animal models, and particularly with isolated follicles encapsulated in alginate matrices and grafted to mice. This summary is designed to guide the reader towards development of next-generation alginate scaffolds, with enhanced properties for follicle encapsulation.

Purpose In the United States, 3.8 million women have a history of breast (BC) or ovarian cancer (OC). Up to 15% of cases are attributable to heritable mutations, which, if identified, provide critical knowledge for treatment and preventive care. It is unknown how many patients who are at high risk for these mutations have not been tested and how rates vary by risk criteria. Methods We used pooled cross-sectional data from three Cancer Control Modules (2005, 2010, 2015) of the National Health Interview Survey, a national in-person household interview survey. Eligible patients were adult females with a history of BC and/or OC meeting select 2017 National Comprehensive Cancer Network eligibility criteria on the basis of age of diagnosis and family history. Outcomes included the proportion of individuals reporting a history of discussing genetic testing with a health professional, being advised to undergo genetic testing, or undergoing genetic testing for BC or OC. Results Of 47,218 women, 2.7% had a BC history and 0.4% had an OC history. For BC, 35.6% met one or more select eligibility criteria; of those, 29.0% discussed, 20.2% were advised to undergo, and 15.3% underwent genetic testing. Testing rates for individual eligibility criteria ranged from 6.2% (relative with OC) to 18.2% (diagnosis ≤ 45 years of age). For OC, 15.1% discussed, 13.1% were advised to undergo, and 10.5% underwent testing. Using only four BC eligibility criteria and all patients with OC, an estimated 1.2 to 1.3 million individuals failed to receive testing. Conclusion Fewer than one in five individuals with a history of BC or OC meeting select National Cancer Comprehensive Network criteria have undergone genetic testing. Most have never discussed testing with a health care provider. Large national efforts are warranted to address this unmet need.

Primary ovarian insufficiency (POI) is a critical fertility defect characterized by an anticipated and silent impairment of the follicular reserve, but its pathogenesis is largely unexplained. The frequent maternal inheritance of POI together with a remarkable dependence of ovarian folliculogenesis upon mitochondrial biogenesis and bioenergetics suggested the possible involvement of a generalized mitochondrial defect. Here, we verified the existence of a significant correlation between blood and ovarian mitochondrial DNA (mtDNA) content in a group of women undergoing ovarian hyperstimulation (OH), and then aimed to verify whether mtDNA content was significantly altered in the blood cells of POI women. We recruited 101 women with an impaired ovarian reserve: 59 women with premature ovarian failure (POF) and 42 poor responders (PR) to OH. A Taqman copy number assay revealed a significant mtDNA depletion (P<0.001) in both POF and PR women in comparison with 43 women of similar age and intact ovarian reserve, or 53 very old women with a previous physiological menopause. No pathogenic variations in the mitochondrial DNA polymerase γ (POLG) gene were detected in 57 POF or PR women with low blood mtDNA content. In conclusion, blood cell mtDNA depletion is a frequent finding among women with premature ovarian aging, suggesting that a still undetermined but generalized mitochondrial defect may frequently predispose to POI which could then be considered a form of anticipated aging in which the ovarian defect may represent the first manifestation. The determination of mtDNA content in blood may become an useful tool for the POI risk prediction. PMID:22879975

Impact of laparoscopic ovarian drilling on serum anti-mullerian hormone levels in patients with anovulatory Polycystic Ovarian syndrome.

Anti-mullerian hormone (AMH) is a marker of the activity of recruitable ovarian follicles. It is useful in the prediction of ovarian reserve. Women with polycystic ovarian syndrome (PCOS) have elevated circulating and intrafollicular AMH levels. Laparoscopic ovarian drilling (LOD) in patients with PCOS destroys ovarian androgen-producing tissue and reduces their peripheral conversion to estrogens. Identifying factors that determine the response of patients with PCOS to LOD will help in selecting the patients who would likely benefit from this treatment. AMH is one such marker that can predict the response to LOD. To evaluate the effect of LOD on serum AMH levels among PCOS responders and non-responders and the usefulness of AMH as a tool in predicting the response to LOD, and to whether there was loss of ovarian function after LOD. This is a prospective cohort study including 30 clomiphene-resistant women with anovulatory PCOS undergoing LOD. Statistical analysis was performed to evaluate the effect of LOD on serum levels of AMH on these women. A significant fall in the levels of AMH was observed after LOD in both responders and non-responders (p<0.001). Women with AMH >8.3 ng/mL showed a significantly lower ovulation rate (33.3%). LOD was not associated with a risk of diminished ovarian reserve. LOD is an effective first-line treatment for women with PCOS who are clomiphene resistant. LOD has no negative effect on ovarian reserve. AMH is a useful marker in predicting the outcome of LOD.

Primary ovarian insufficiency (POI) is a critical fertility defect characterized by an anticipated and silent impairment of the follicular reserve, but its pathogenesis is largely unexplained. The frequent maternal inheritance of POI together with a remarkable dependence of ovarian folliculogenesis upon mitochondrial biogenesis and bioenergetics suggested the possible involvement of a generalized mitochondrial defect. Here, we verified the existence of a significant correlation between blood and ovarian mitochondrial DNA (mtDNA) content in a group of women undergoing ovarian hyperstimulation (OH), and then aimed to verify whether mtDNA content was significantly altered in the blood cells of POI women. We recruited 101 women with an impaired ovarian reserve: 59 women with premature ovarian failure (POF) and 42 poor responders (PR) to OH. A Taqman copy number assay revealed a significant mtDNA depletion (P<0.001) in both POF and PR women in comparison with 43 women of similar age and intact ovarian reserve, or 53 very old women with a previous physiological menopause. No pathogenic variations in the mitochondrial DNA polymerase γ (POLG) gene were detected in 57 POF or PR women with low blood mtDNA content. In conclusion, blood cell mtDNA depletion is a frequent finding among women with premature ovarian aging, suggesting that a still undetermined but generalized mitochondrial defect may frequently predispose to POI which could then be considered a form of anticipated aging in which the ovarian defect may represent the first manifestation. The determination of mtDNA content in blood may become an useful tool for the POI risk prediction.

Fertility after uterine artery embolization: a review.

PubMed

McLucas, Bruce; Voorhees, William D; Elliott, Stephanie

2016-01-01

Uterine artery embolization (UAE) research has largely been focused on women over 40 years, yet women of reproductive age undergo UAE without any increased morbidity. Some physicians refrain from recommending UAE to women in this age group because of some research findings showing a negative effect on fertility. This review presents a comprehensive discussion of the fertility potential of women undergoing UAE, in terms of pregnancy rates and complications as well as ovarian function and reserve. Findings indicate many benefits for women desiring fertility who undergo UAE over traditional myomectomy.

Background: This study aims to identify prognostic factors and to develop a risk model predicting survival in patients undergoing secondary cytoreductive surgery (SCR) for recurrent epithelial ovarian cancer. Methods: Individual data of 1100 patients with recurrent ovarian cancer of a progression-free interval at least 6 months who underwent SCR were pooled analysed. A simplified scoring system for each independent prognostic factor was developed according to its coefficient. Internal validation was performed to assess the discrimination of the model. Results: Complete SCR was strongly associated with the improvement of survival, with a median survival of 57.7 months, when compared with 27.0 months in those with residual disease of 0.1–1 cm and 15.6 months in those with residual disease of >1 cm, respectively (P<0.0001). Progression-free interval (⩽23.1 months vs >23.1 months, hazard ratio (HR): 1.72; score: 2), ascites at recurrence (present vs absent, HR: 1.27; score: 1), extent of recurrence (multiple vs localised disease, HR: 1.38; score: 1) as well as residual disease after SCR (R1 vs R0, HR: 1.90, score: 2; R2 vs R0, HR: 3.0, score: 4) entered into the risk model. Conclusion: This prognostic model may provide evidence to predict survival benefit from secondary cytoreduction in patients with recurrent ovarian cancer. PMID:21878937

Massive Broad Ligament Cellular Leiomyoma with Cystic Change: A Diagnostic Dilemma.

2016-04-01

Leiomyomas are known to arise from uterus, but rarely from broad ligament. Further, cellular leiomyoma of broad ligament is the least common variant reported in literature. The diagnostic dilemma arises when leiomyomas undergo degenerative changes. This poses both clinical and radiological difficulty in differentiating with an ovarian tumour. We present an unusual case of a huge broad ligament mass measuring 29x19x09cm, mimicking an ovarian tumour both clinically and radiologically. Histopathology revealed cellular leiomyoma of broad ligament with cystic and myxoid degeneration hereby being the second case reported in literature. This case is being presented not only because of the rare incidence but also due to its diagnostic confusion with ovarian malignancy on clinical evaluation and radiological findings.

To evaluate controlled ovarian stimulation cycles using the GnRH antagonist ganirelix in combination with the recombinant FSH, follitropin-beta, in women with polycystic ovary syndrome (PCOS). Prospective, nonrandomized clinical study. Hospital-based infertility practice. Twenty women with PCOS planning to undergo ovarian stimulation. Fasting glucose and insulin levels were used to calculate insulin resistance ratios (FG/I). After pretreatment with oral contraceptives, serum LH levels were determined, and 250 microg ganirelix was administered on cycle day 2. Upon suppression of LH, concurrent ganirelix and follitropin-beta therapy (morning ganirelix and evening follitropin-beta) was started and continued until the day of hCG. Days of stimulation, dose of follitropin-beta, pregnancy, and ongoing pregnancy were compared based on FG/I ratios. One dose of ganirelix effectively suppressed LH levels in all patients. All patients ovulated as documented by a rise in progesterone. Significant differences were observed between the insulin-resistant and non-insulin-resistant groups for both days of stimulation and dose of follitropin-beta. The overall clinical pregnancy rate was 44.4%, with an ongoing pregnancy rate of 27.8%. In this preliminary study, we demonstrate the effectiveness of a concurrent ganirelix and follitropin-beta therapy for ovarian stimulation in women with PCOS.

The aim of the study was to evaluate the influence of type of GnRH-analog used during controlled ovarian hyperstimulation (COH) on the outcome of in vitro fertilization (IVF) cycles. All consecutive women aged < or = 35 years admitted to our IVF unit from January 2001 to December 2004 were enrolled in the study. Only patients undergoing up to their third IVF cycle attempt were included. Ovarian stimulation characteristics, number of oocytes retrieved, number of embryos transferred, and clinical pregnancy rate were compared between women given GnRH-agonist or GnRH-antagonist during COH. Four hundred and eighty-seven consecutive IVF cycles were evaluated, 226 in the agonist group and 261 in the antagonist group. A clinical pregnancy was achieved in 93 patients in the agonist group (pregnancy rate 41.2% per cycle) and 66 patients in the antagonist grup (pregnancy rate 25.3%); this difference was statistically significant (p < 0.01). The agonist group also used significantly more gonadotropin ampoules, required longer stimulation, and had higher estradiol levels on the day of human chorionic gonadotropin administration. The midluteal long GhRH-agonist suppressive protocol should be the protocol of choice in young patients in their first three IVF cycle attempts.

The objective was to evaluate the effect of endometrial biopsy (EB) on intrauterine insemination (IUI) outcome in controlled ovarian stimulation (COS) cycle. Prospective randomized control study. Tertiary care center. A total of 251 subjects were enrolled in the study. Subjects undergoing COS with IUI were randomly allocated into three groups. Group A: EB was taken between D19 and 24 of the spontaneous menstrual cycles that precedes the fertility treatment and IUI, which was done in next cycle (n = 86). Group B: EB was taken before D6 of the menstrual cycle, and fertility treatment and IUI was done in the same cycle (n = 90). Group C: (control group) no EB in previous 3 cycle (n = 75). Clinical pregnancy rate (CPR). Clinical pregnancy rate was 19.77%, 31.11%, and 9.3% for Group A, Group B, and Group C, respectively. The results show a highly significant value for the paired t-test of intervention Group B and control Group C of the cases (P = 0.000957). CPR was maximum after first cycle of ovulation induction and IUI following EB scratch in both Groups A and in Group B (P < 0.001). Endometrial biopsy done in early follicular phase in the same cycle of stimulation with IUI gives better CPR as compared with EB done in the luteal phase of the previous cycle.

We aimed to characterize the association between levels of serum and follicular fluid (FF) adipocytokines, reflected by the leptin to adiponectin ratio (L:A ratio), and oocyte quality and in vitro embryo development in women undergoing assisted reproduction. We also aimed to assess whether follicular hormonal pathways mediate this interaction. We prospectively collected FF from up to four individual preovulatory follicles (n = 76) and fasting sera from women (n = 31) without endocrinopathies undergoing in vitro fertilization (IVF) at a university-based center for assisted reproduction. Leptin, total adiponectin, insulin, insulin-like growth factor 1 (IGF-1), and ovarian steriods were measured using enzyme immunoassay. Oocyte maturity, fertilization, and embryo development were assessed. FF leptin was similar to serum levels while FF adiponectin was lower. FF leptin (27.10 ± 4.05 ng/mL) and the L:A ratio (11.48E-3 ± 2.57E-3) were related to FF insulin (R (2) = 0.370 and 0.419, p < 0.001) but not to ovarian steroids or IGF-1, whereas FF adiponectin ( 4.22 ± 0.52 ug/mL) correlated only with leptin (R (2) = -0.138, p = 0.001). Oocytes from a high FF L:A ratio environment were 81 % (RR 1.81 [95%CI 0.97-3.37]) more likely to undergo successful cleavage and 117 % (RR 2.17 [95 % CI 1.06-4.44]) more likely to obtain viable cleavage morphology compared to a low FF L:A ratio environment, even when adjusted for FF insulin, an independent predictor of cleavage. Certain adipocytokines, particularly the L:A ratio in the FF of the preovulatory follicle, are related to successful in vitro embryo development. This action may be independent of FF insulin.

Aromatase inhibitors (AI) have been introduced to reduce estrogen exposure in women with estrogen-sensitive cancer undergoing ovarian stimulation for oocyte/embryo cryopreservation. There have been questions regarding whether the addition of AI and the presence of BRCA mutations affect cycle outcomes. We sought to determine the impact of letrozole and BRCA mutations on fertility preservation (FP) cycle outcomes of patients undergoing ovarian stimulation with an antagonist protocol. The data were generated by the secondary analysis of a prospective database of all females diagnosed with cancer who underwent embryo or oocyte cryopreservation for FP. The final analysis included 145 patients stimulated with an antagonist protocol either using letrozole combined with recombinant follicle-stimulating hormone (rFSH; LF, n = 118) or rFSH alone (FA, n = 24). The mean number of total (15.6 [7.9] vs 10.2 [7.8]; P = .004) and mature oocytes (10.4 [5.1] vs 7.8 [3.5]; P = .044) and embryos frozen (7.7 [5.3] vs 5.3 [2.7]; P = .043) were significantly higher after LF stimulation versus FA. In the LF group, women with BRCA mutations produced significantly fewer oocytes (11.0 [8.0] vs 16.4 [7.7], P = .015) and embryos (5.1 [4.4] vs 8.2 [4.7], P = .013), compared to those who were mutation negative. After adjusting for age, body mass index, baseline FSH level, and BRCA status, LF protocol still resulted in higher number of total oocytes (95% confidence interval [CI]: 1.9 to 3.6; P = .002) mature oocyte (95% CI: 0.3 to 1.4; P = .028), and embryo yield (95% CI: 0.7 to 1.4; P = .015). In women with cancer undergoing FP, letrozole appears to enhance response to ovarian stimulation while the presence of BRCA mutations is associated with lower oocyte and embryo yield.

Biomarkers of ovarian reserve as predictors of reproductive potential.

PubMed

Steiner, Anne Z

2013-11-01

The size of the oocyte pool, the ovarian reserve, can determine a woman's reproductive stage. Chronologic age, anti-Müllerian hormone (AMH) levels, early follicular phase follicle-stimulating hormone levels, and early follicular phase inhibin B levels are correlated with ovarian reserve. Therefore, these biomarkers of ovarian reserve should serve as predictors of reproductive potential. Clinical and epidemiologic studies suggest that historical and laboratory biomarkers of ovarian reserve are associated with natural and treatment-related fertility. However, controversy remains as to their ability to predict reproductive potential. For infertile women undergoing assisted reproductive technology treatment, these biomarkers tend to be highly specific but not sensitive for cycle failure (nonpregnancy). While these biomarkers are being used as "fertility tests" in the general population, their value as predictors of unassisted fertility is still uncertain. Among laboratory biomarkers, AMH appears to have the most promise; however, further studies are needed to refine cutoff values and to determine test characteristics in the prediction of natural fertility or infertility in the general population.

We aimed to determine the effects of dietary aspirin treatment on ovarian cancer incidence and progression in the hen as a model for the human disease. Hens were fed a standard layer diet (control) or the same diet containing 0.1% aspirin for 1 year. Liver prostaglandin E(2) (PGE(2)) was measured using an enzyme immunoassay. Incidence and stage of ovarian cancer were determined through necropsy and immunohistochemical analysis of ovarian sections for each hen. Aspirin treatment decreased liver PGE(2) in treated hens as compared to control hens. Treatment with aspirin did not decrease ovarian cancer incidence. Significantly more control hens developed late stage ovarian cancer than early stage, while the same was not true for aspirin-treated hens. Hens that developed ovarian cancer, even early ovarian cancer, produced significantly fewer eggs in the year prior to diagnosis than hens without ovarian cancer. Aspirin treatment may inhibit the progression of ovarian cancer in the hen and egg production may be used to identify hens with early stages of the disease.

The most frequent ovarian germ cell tumors are mature cystic teratomas (MCTs), composing 10-25% of all ovarian neoplasms. MCTs have the potential of undergoing malignant transformation, typically in postmenopausal women, with a frequency of 0.17-3%, with squamous cell carcinoma being the most common malignant tumor arising from MCT. We present the rare clinical entity of a squamous cell carcinoma arising from a mature cystic teratoma in a 56-year-old premenopausal woman as well as diagnostic and therapeutic route followed.

New and often aggressive treatment schemes allow the successful healing of many young patients with cancer, but the price the young women have to pay is high: many of them lose ovarian function and fertility. Due to the improved long-term survival of adolescents and young women with malignancies undergoing gonadotoxic chemotherapy, preservation of future fertility has been the focus of recent ubiquitarian interest. A feasible solution is the cryopreservation of ovarian tissue. Ovarian tissue, after thawing, can be used in three different ways: 1. grafted into its normal site (orthotopic); 2. grafted into a site other than its normal position (heterotopic), necessitating recourse to in vitro fertilization (IVF); 3. grown and in vitro matured in order to obtain metaphase II oocytes for an IVF program. It is believed that protein supplementation, in cryopreservation solution, is essential for improving ovarian tissue cryopreservation. The aim of this study was to evaluate the ultrastructural appearance of human ovarian tissue cryopreserved in 1.5 M 1,2 propanediol (PROH), 0.2 M sucrose using different protein sources: fetal calf serum (FCS), plasmanate or syntetic serum substitute (SSS). Fresh and frozen/thawed ovarian tissues were compared by transmission electron microscope (TEM), to evaluate the appearance of stromal and follicle cells as affected by different protein sources. Our data indicate that FCS is a better protein support for ovarian tissue cryopreservation when compared to SSS or Plasmanate. In addition the follicles are more resistant to the cryopreservation with respect to stroma.

Ovarian sensitivity index is strongly related to circulating AMH and may be used to predict ovarian response to exogenous gonadotropins in IVF

PubMed Central

2011-01-01

Background Serum anti-Mullerian hormone (AMH) is currently considered the best marker of ovarian reserve and of ovarian responsiveness to gonadotropins in in-vitro fertilization (IVF). AMH assay, however, is not available in all IVF Units and is quite expensive, a reason that limits its use in developing countries. The aim of this study is to assess whether the "ovarian sensitivity index" precisely reflects AMH so that this index may be used as a surrogate for AMH in prediction of ovarian response during an IVF cycle. Methods AMH serum levels were measured in 61 patients undergoing IVF with a "long" stimulation protocol including the GnRH agonist buserelin and recombinant follicle-stimulating hormone (rFSH). Patients were divided into four subgroups according to the percentile of serum AMH and their ovarian stimulation was prospectively followed. Ovarian sensitivity index (OSI) was calculated dividing the total administered FSH dose by the number of retrieved oocytes. Results AMH and OSI show a highly significant negative correlation (r = -0.67; p = 0.0001) that is stronger than the one between AMH and the total number of retrieved oocytes and than the one between AMH and the total FSH dose. Conclusions OSI reflects quite satisfactory the AMH level and may be proposed as a surrogate of AMH assay in predicting ovarian responsiveness to FSH in IVF. Being very easy to calculate and costless, its use could be proposed where AMH measurement is not available or in developing countries where limiting costs is of primary importance. PMID:21824441

To compare histologic and ultrastructural characteristics of fresh and frozen-thawed human ovarian cortical tissue grafted into nude mice. Experimental prospective study. An academic research environment. Ovarian biopsy specimens were obtained from 13 women undergoing laparoscopy for tubal ligation or infertility. Forty nude mice. A minilaparotomy was performed to place fresh and frozen-thawed ovarian grafts subcutaneously (sc) or intraperitoneally (ip). Removal of the ovarian grafts was performed at 24 days. [1] the follicular population, [2] fibrosis, [3] vascularization of the grafted tissue, and [4] ultrastructural evaluation. A greater fibrosis relative surface area was noted in frozen-thawed transplanted tissue than in fresh transplants. Regardless of this fibrosis, a similar follicular density was observed in fresh and frozen-thawed ovarian tissue 24 days after transplantation. Active angiogenesis was proved by both immunohistochemical study of the vascular endothelial growth factor and morphometric study of the vascular network. Normal ultrastructural characteristics were noted in frozen-thawed ovarian biopsies. Angiogenesis allows implantation of the graft even if it has been cryopreserved and thawed similarly to implantation of fresh tissue. The greater fibrosis observed in grafts after cryopreservation and implantation does not seem to affect the primordial and primary ovocyte population and their ultrastructural characteristics, but further studies must be conducted to prove that after cryopreservation and transplantation, ovocytes may achieve full maturation and fertilization.

To compare cumulative live birth rate according to the rate of use of metaphase II (MII) oocytes in conventional ovarian stimulation protocols for in vitro fertilization (IVF) or intracytoplasmic sperm injection. In a cohort study, patients aged 18-38 years undergoing their first IVF treatment at one US center were enrolled between February 1, 2009, and August 31, 2013. Ovarian response was categorized by the yield of MII oocytes (low: 1-2; intermediate: 3-6; high: ≥7). The main outcome measure was cumulative live birth rate over a 6-month period. Among 250 participants, 3240 oocytes (mean±SEM 12.96±0.50) were retrieved and there were 152 (60.8%) live births. Overall, 172 (68.8%) participants had a high oocyte yield, 61 (24.4%) an intermediate yield, and 17 (6.8%) a low yield. The cumulative live birth rate was 58.8% (10/17) in the low-yield group, 55.7% (34/61) in the intermediate-yield group, and 62.8% (108/172) in the high-yield group (P=0.35). In conventional ovarian stimulation, live birth rate is not affected by the ovarian response. Whether oocytes produced from a low ovarian response are biologically more effective than oocytes obtained from a high ovarian response remains to be determined.

Prospective, randomized, controlled clinical study. An academic clinical research center. Women with PCOS and anovulatory infertility undergoing COS/IUI. Recombinant FSH therapy was started on day 3. In women assigned to the control group (n = 47), treatment was continued up to the day of hCG administration. In patients assigned to receive GnRH antagonist (n = 42), ganirelix was added when the leading follicle was > or =14 mm. Pregnancy rates, serum E(2), P, and LH levels, and follicle numbers at hCG day, prevalence of premature luteinization, and cost of stimulation. Serum E(2), P, and LH levels were significantly lower in the ganirelix group. Although premature luteinization and cycle cancellation was encountered less in the ganirelix group, the pregnancy rates per cycle were similar (15.4% vs. 10.7%). Patients would pay 6,153 dollars more for each pregnancy when using ganirelix. Gonadotropin-releasing hormone antagonist resulted in more monofollicular development, less premature luteinization, and less cycle cancellation in IUI cycles of patients with PCOS; however, the cost of stimulation increased without an improvement in pregnancy rates.

In women undergoing IVF, are urinary bisphenol A (BPA) concentrations associated with ovarian response and early reproductive outcomes, including oocyte maturation and fertilization, Day 3 embryo quality and blastocyst formation? Higher urinary BPA concentrations were found to be associated with decreased ovarian response, number of fertilized oocytes and decreased blastocyst formation. Experimental animal and in vitro studies have reported associations between BPA exposure and adverse reproductive outcomes. We previously reported an association between urinary BPA and decreased ovarian response [peak serum estradiol (E(2)) and oocyte count at the time of retrieval] in women undergoing IVF; however, there are limited human data on reproductive health outcomes, such as fertilization and embryo development. Prospective preconception cohort study. One hundred and seventy-four women aged 18-45 years and undergoing 237 IVF cycles were recruited at the Massachusetts General Hospital Fertility Center, Boston, MA, USA, between November 2004 and August 2010. These women were followed until they either had a live birth or discontinued treatment. Cryothaw and donor egg cycles were not included in the analysis. Urinary BPA concentrations were measured by online solid-phase extraction-high-performance liquid chromatography-isotope dilution-tandem mass spectrometry. Mixed effect models, poisson regression and multivariate logistic regression models were used wherever appropriate to evaluate the association between cycle-specific urinary BPA concentrations and measures of ovarian response, oocyte maturation (metaphase II), fertilization, embryo quality and cleavage rate. We accounted for correlation among multiple IVF cycles in the same woman using generalized estimating equations. The geometric mean (SD) for urinary BPA concentrations was 1.50 (2.22) µg/l. After adjustment for age and other potential confounders (Day 3 serum FSH, smoking, BMI), there was a significant linear dose-response association between increased urinary BPA concentrations and decreased number of oocytes (overall and mature), decreased number of normally fertilized oocytes and decreased E(2) levels (mean decreases of 40, 253 and 471 pg/ml for urinary BPA quartiles 2, 3 and 4, when compared with the lowest quartile, respectively; P-value for trend = 0.001). The mean number of oocytes and normally fertilized oocytes decreased by 24 and 27%, respectively, for the highest versus the lowest quartile of urinary BPA (trend test P < 0.001 and 0.002, respectively). Women with urinary BPA above the lowest quartile had decreased blastocyst formation (trend test P-value = 0.08). Potential limitations include exposure misclassification due to the very short half-life of BPA and its high variability over time; uncertainty about the generalizability of the results to the general population of women conceiving naturally and limited sample. The results from this extended study, using IVF as a model to study early reproductive health outcomes in humans, indicate a negative dose-response association between urinary BPA concentrations and serum peak E(2) and oocyte yield, confirming our previous findings. In addition, we found significantly decreased metaphase II oocyte count and number of normally fertilizing oocytes and a suggestive association between BPA urinary concentrations and decreased blastocyst formation, thus indicating that BPA may alter reproductive function in susceptible women undergoing IVF.

What is the current management of women with ovarian endometriomas undergoing assisted reproductive treatment (ART) in the UK? It appears that the majority of gynaecologists in the UK offer surgery (mostly cystectomy) for endometriomas prior to ART, regardless of the presence of symptoms. The ideal management of endometriomas in women undergoing ART remains controversial and presents a dilemma to reproductive specialists. This was a national cross-sectional survey. A total of 388 gynaecologists completed the questionnaire. All clinicians fully registered with the Royal College of Obstetricians and Gynaecologists were contacted. An 11-item survey was administered electronically using Survey Monkey software. Quantitative data were analysed using descriptive and comparative statistics. The majority of responders were consultants (65%), 25% practiced ART and 65% performed laparoscopic surgery. Overall, 95% of responders would offer surgery for endometriomas in women undergoing ART, either on the basis of the size (>3-5 cm) of the endometrioma (52%), the presence of symptoms (16%), the presence of multiple/bilateral endometriomas (2%), regardless of the size and symptoms (19%) or only to women undergoing IVF (6%). The remaining 5% of responders would not offer surgery before ART. Excision was the most common surgical modality (68%), followed by ablation (25%). Laparoscopic surgeons were almost twice as likely to 'offer surgery to all patients with endometriomas prior to ART' compared with clinicians performing laparotomy (22 versus 12%, P < 0.001). Our overall response rate, with answers to the questionnaire, was low (15%). However, the response rate amongst reproductive specialists was estimated at 60%. It is possible that there might have been an element of bias towards over-representation of responders who are more concerned about 'normalization' of the pelvic anatomy. Furthermore, our survey relied on self-reporting of practice and it is possible that being presented with a list of 'ideal' options may have resulted in respondent bias. Despite the available evidence that surgery for endometriomas does not improve the outcome of ART and may damage ovarian reserve, it seems that the majority of gynaecologists in the UK offer ovarian cystectomy to their patients.

To report an autograft of ovarian tissue in the incision of the surgical trocar during laparoscopic surgery and to assess the potentiality of grafting of ovarian parenchyma in nonpelvic tissue in humans. A case report. Instituto de Fertilidad y Ginecología de Buenos Aires (IFER), Buenos Aires, Argentina. Infertile patient undergoing surgery due to an endometriotic cyst of the left ovary. Laparoscopic cystectomy. Accidental retention of a portion of the capsule and adjacent ovarian tissue of the endometrioma in SC cellular tissue. Months after surgery, a SC tumor was formed under the surgical incision. It was subsequently excised. Observation of tumor growth during menstrual cycles and ovulation induction; anatomopathologic study of the tissue after its extirpation. The tumor grew spontaneously in the periovulatory period and during treatments of ovulation induction. The anatomopathologic report of the tumor, removed 15 months after the first surgery, revealed functioning ovarian tissue with vessels of neoformation. This is the first description of autografted ovarian tissue in humans. We describe that the ovary can maintain its ovulatory function even in the absence of its pedicel. Also, we suggest that extirpation of surgical material through the incision of the trocar is not recommended, as the possibility of "sowing" or of autografts may occur.

Inositol Treatment and ART Outcomes in Women with PCOS.

Garg, Deepika; Tal, Reshef

Polycystic ovary syndrome (PCOS) affects 5-10% of women in reproductive age and is characterized by oligo/amenorrhea, androgen excess, insulin resistance, and typical polycystic ovarian morphology. It is the most common cause of infertility secondary to ovulatory dysfunction. The underlying etiology is still unknown but is believed to be multifactorial. Insulin-sensitizing compounds such as inositol, a B-complex vitamin, and its stereoisomers (myo-inositol and D-chiro-inositol) have been studied as an effective treatment of PCOS. Administration of inositol in PCOS has been shown to improve not only the metabolic and hormonal parameters but also ovarian function and the response to assisted-reproductive technology (ART). Accumulating evidence suggests that it is also capable of improving folliculogenesis and embryo quality and increasing the mature oocyte yield following ovarian stimulation for ART in women with PCOS. In the current review, we collate the evidence and summarize our current knowledge on ovarian stimulation and ART outcomes following inositol treatment in women with PCOS undergoing in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI).

We aim to evaluate the IVF-ET outcome in patients receiving a high daily dose (300 IU) of gonadotropins during controlled ovarian hyperstimulation (COH) for IVF and to assess the role of increasing the daily dose to 450 IU on improving outcome. All consecutive women admitted to our IVF unit during an 11 year period who underwent COH consisting of daily gonadotropin dose of 300 IU were included in the study. The ovarian stimulation characteristics, number of oocytes retrieved, number of embryo transferred and pregnancy rate were assessed. We also evaluated the subsequent cycle, using daily gonadotropin doses of 450 IU, among those patients who did not conceive using the 300 IU daily gonadotropin dose. Nine hundred and forty-nine consecutive IVF cycles were evaluated. Patients who conceived using the daily gonadotropin dose of 300 IU (n = 133, 14% pregnancy rate) had significantly longer stimulation, yielded higher numbers of oocytes retrieved, fertilization rate and number of embryos transferred, compared to those who did not conceive. Moreover, while comparing IVF cycles using daily gonadotropin doses of 300 IU to 450 IU (n = 117), no in-between group differences were observed, except for significantly higher yields of oocytes retrieved. Moreover, cycles using daily gonadotropin doses of 450 IU resulted in a 7.7 live-birth rate. In poor responders undergoing COH with a daily gonadotropin dose of 300 IU, increasing the dose to 450 IU resulted in significantly higher oocyte yields and a reasonable live birth rate.

Patients undergoing gynecology laparoscopy frequently experience shoulder pain as a common postoperative complication. Considering diaphragm stimulation in its pathophysiology, there are some advice to prevent or control this special form of referral pain. The current study aimed to assess the prophylactic effect of preoperative administration of oral gabapentin to prevent Post Laparoscopic Shoulder Pain (PLSP) after laparoscopic ovarian cystectomy. In a randomized, double blind, placebo controlled trial 40 female patients who were candidates to have elective laparoscopic ovarian cystectomy, received uniformed capsules containing gabapentin 600 mg or placebo 30 minutes before anesthesia induction. All patients had the American Society of Anesthesiologists (ASA) Physical Status of I-II and none had pervious abdominal surgery. Thereafter, the presence of side effects and PLSP and its severity was assessed by Visual Analog Scale (VAS) in the beginning of surgery and 2, 6, 12 hours after the surgery. Comparing the gabapentin (n = 20) and placebo (n = 20) groups, basic characteristics including age (P = 0.446), Body Mass Index (BMI) (P = 0.876), pregnancy history (P = 0.660), and surgery time (P = 0.232) were statistically similar. PLSP occurrence was less frequent in the gabapentin group (45%) compared with the placebo group (75%) (P = 0.053), while In gabapentin group the VAS scores were lower in 2(P = 0.004), 6 (P = 0.132), and 12 (P = 0.036) hours, post operatively. Prophylactic gabapentin administration could be considered as an effective and safe intervention to reduce occurrence and severity of PLSP after gynecologic laparoscopic cystectomy.

Progestin-primed ovarian stimulation (PPOS) protocol has recently been demonstrated to be an novel regimen for preventing premature LH surges during controlled ovarian hyperstimulation (COH) in combination with frozen-thawed embryo transfer (FET). Our prospective controlled study was to explore the effect of human chorionic gonadotropin (hCG) contained in human menopausal gonadotropin (hMG) on the clinical outcomes in normalovulatory women undergoing COH with PPOS. A total of 180 patients were allocated into three groups according to the gonadotropin (Gn) used: group A (human menopausal gonadotropin, hMG-A), group B (hMG-B) or group C (follicle stimulating hormone, FSH). The primary outcome measured was the number of oocytes retrieved. The number of oocytes retrieved in group A B C was 10.72±5.78 11.33±5.19and13.38±8.97, respectively, with no statistic significance (p>0.05). Other embryological indicators were also similar (p>0.05). The concentration of serum and urinary β-hCG on the trigger day in group A and B were not associated with embryo results (p>0.05). There was no significant differences in the clinical pregnancy rate (41.67% vs. 51.56% vs. 39.51%, p>0.05) and implantation rate (31.58%vs. 34.75%vs.25.33%) after FET among the three groups. Thus the clinical characteristics were not affected by the hCG contained in hMG in normalovulatory women treated with PPOS. PMID:29152085

We developed a new technique of temporary ovarian transposition (OT) for prepubertal girls undergoing brachytherapy. The aim of this study was to describe it, assess its feasibility and safety and calculate the dose delivered to the ovary in order to prove its efficacy. Sixteen prepubertal patients underwent temporary OT for brachytherapy at our center from March 2001 to December 2012. OT was done either by laparotomy or by laparoscopy. In all patients, the ovaries were grasped with an atraumatic forceps and mobilized above the iliac crest level as high as possible without any dissection or division of the ovarian ligaments or of the fallopian tube. They were sutured to the anterior abdominal wall by a transfixing stitch of non-dissolvable suture knotted on the outside of the patient on a pledget. Median age at surgery was 3 years (range: 2-9 years). The integrity of the fallopian tube was respected and not a single ligament was dissected or divided. None of the patients had intraoperative or postoperative complications. The stitches were retrieved after completion of irradiation and the ovaries in all the patients fell back into the pelvis. The calculated median radiation dose to the ovary was 1.4 Gy (range: 0.4-2.4 Gy). This surgical technique is simple and safe, either by laparotomy or by laparoscopy. It meets the radiation and physical constraints in prepubertal girls with vaginal or bladder RMS. However, longer follow-up is required to assess the ovarian function. Copyright © 2014 Elsevier Inc.

[First line management without IVF of infertility related to endometriosis: Result of medical therapy? Results of ovarian superovulation? Results of intrauterine insemination? CNGOF-HAS Endometriosis Guidelines].

Using the structured methodology of French guidelines (HAS-CNGOF), the aim of this chapter was to formulate good practice points (GPP), in relation to optimal non-ART management of endometriosis related to infertility, based on the best available evidence in the literature. This guideline was produced by a group of experts in the field including a thorough systematic search of the literature (from January 1980 to March 2017). Were included only women with endometriosis related to infertility. For each recommendation, a grade (A-D, where A is the highest quality) was assigned based on the strength of the supporting evidence. Management of endometriosis related to infertility should be multidisciplinary and take account into the pain, the global evaluation of infertile couple and the different phenotypes of endometriotic lesions (good practice point). Hormonal treatment for suppression of ovarian function should not prescribe to improve fertility (grade A). After laproscopy for endometriosis related to infertility, the Endometriosis Fertility Index should be used to counsel patients regarding duration of conventional treatments before undergoing ART (grade C). After laparoscopy surgery for infertile women with AFS/ASRM stage I/II endometriosis or superficial peritoneal endometriosis, controlled ovarian stimulation with or without intrauterine insemination could be used to enhance non-ART pregnancy rate (grade C). Gonadotrophins should be the first line therapy for the stimulation (grade B). The number of cycles before referring ART should not exceed up to 6 cycles (good practice point). No recommendation can be performed for non-ART management of deep infiltrating endometriosis or endometrioma, as suitable evidence is lacking. Non-ART management is a possible option for the management of endometriosis related to infertility. Endometriosis Fertilty Index could be a useful tool for subsequent postoperative fertility management. Controlled ovarian stimulation can be proposed. Copyright © 2018 Elsevier Masson SAS.

This paper explores patients' views and experiences of undergoing treatment-focused BRCA1 and BRCA2 genetic testing (TFGT), either offered following triaging to clinical genetics (breast cancer) or as part of a mainstreamed care pathway in oncology (ovarian cancer). Drawing on 26 in-depth interviews with patients with breast or ovarian cancer who had undergone TFGT, this retrospective study examines patients' views of genetic testing at this point in their care pathway, focusing on issues, such as initial response to the offer of testing, motivations for undergoing testing, and views on care pathways. Patients were amenable to the incorporation of TFGT at an early stage in their cancer care irrespective of (any) prior anticipation of having a genetic test or family history. While patients were glad to have been offered TFGT as part of their care, some questioned the logic of the test's timing in relation to their cancer treatment. Crucially, patients appeared unable to disentangle the treatment role of TFGT from its preventative function for self and other family members, suggesting that some may undergo TFGT to obtain information for others rather than for self.

Kisspeptin as a promising oocyte maturation trigger for in vitro fertilisation in humans.

2017-08-01

The aim of this review is to analyse the effectiveness of exogenous kisspeptin administration as a novel alternative of triggering oocyte maturation, instead of currently used triggers such as human chorionic gonadotropin (hCG) or gonadotropin releasing hormone (GnRH) agonist, in women undergoing in vitro fertilisation (IVF) treatment. Kisspeptin has been considered a master regulator of two modes of GnRH and hence gonadotropin secretion, pulses and surges. Administration of kisspeptin-10 and kisspeptin-54 induces the luteinising hormone (LH) surge required for egg maturation and ovulation in animal investigations and LH release during the preovulatory phase of the menstrual cycle and hypothalamic amenorrhoea in humans. Exogenous kisspeptin-54 has been successfully administered as a promising method of triggering oocyte maturation, following ovarian stimulation with gonadotropins and GnRH antagonists in women undergoing IVF, due to its efficacy considering achieved pregnancy rates compared to hCG and GnRH agonists. Also, its safety in patients at high risk of developing ovarian hyperstimulation syndrome is noteworthy. Nevertheless, further studies would be desirable to establish the optimal trigger of egg maturation and to improve the reproductive outcome for women undergoing IVF treatment.

To evaluate the effects of a prolonged duration of gonadotropin-releasing hormone agonist (GnRH-a) in pituitary down-regulation for controlled ovarian hyperstimulation (COH) on the live-birth rate in nonendometriotic women undergoing in vitro fertilization and embryo transfer (IVF-ET). Retrospective cohort study. University-affiliated hospital. Normogonadotropic women undergoing IVF. Three hundred seventy-eight patients receiving a prolonged pituitary down-regulation with GnRH-a before ovarian stimulation and 422 patients receiving a GnRH-a long protocol. Live-birth rate per fresh ET. In comparison with the long protocol, the prolonged down-regulation protocol required a higher total dose of gonadotropins. A lower serum luteinizing hormone (LH) level on the starting day of gonadotropin and the day of human chorionic gonadotropin (hCG) and a fewer number of oocytes and embryos were observed in the prolonged down-regulation protocol. However, the duration of stimulation and number of high-quality embryos were comparable between the two groups. A statistically significantly higher implantation rate (50.27% vs. 39.69%), clinical pregnancy rate (64.02% vs. 56.87%) and live-birth rate per fresh transfer cycle (55.56% vs. 45.73%) were observed in the prolonged protocol. Prolonged down-regulation in a GnRH-a protocol might increase the live-birth rates in normogonadotropic women. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

To observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients. Forty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM. Compared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01). CCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

OBJECTIVE: The objective was to evaluate the effect of endometrial biopsy (EB) on intrauterine insemination (IUI) outcome in controlled ovarian stimulation (COS) cycle. DESIGN: Prospective randomized control study. SETTING: Tertiary care center. MATERIALS AND METHODS: A total of 251 subjects were enrolled in the study. Subjects undergoing COS with IUI were randomly allocated into three groups. Group A: EB was taken between D19 and 24 of the spontaneous menstrual cycles that precedes the fertility treatment and IUI, which was done in next cycle (n = 86). Group B: EB was taken before D6 of the menstrual cycle, and fertility treatment and IUI was done in the same cycle (n = 90). Group C: (control group) no EB in previous 3 cycle (n = 75). MAIN OUTCOME MEASURE: Clinical pregnancy rate (CPR). RESULTS: Clinical pregnancy rate was 19.77%, 31.11%, and 9.3% for Group A, Group B, and Group C, respectively. The results show a highly significant value for the paired t-test of intervention Group B and control Group C of the cases (P = 0.000957). CPR was maximum after first cycle of ovulation induction and IUI following EB scratch in both Groups A and in Group B (P < 0.001). CONCLUSIONS: Endometrial biopsy done in early follicular phase in the same cycle of stimulation with IUI gives better CPR as compared with EB done in the luteal phase of the previous cycle.

Acupuncture is widely used by women undergoing in vitro fertilization (IVF), although the evidence for efficacy is conflicting. To determine the efficacy of acupuncture compared with a sham acupuncture control performed during IVF on live births. A single-blind, parallel-group randomized clinical trial including 848 women undergoing a fresh IVF cycle was conducted at 16 IVF centers in Australia and New Zealand between June 29, 2011, and October 23, 2015, with 10 months of pregnancy follow-up until August 2016. Women received either acupuncture (n = 424) or a sham acupuncture control (n = 424). The first treatment was administered between days 6 to 8 of follicle stimulation, and 2 treatments were administered prior to and following embryo transfer. The sham control used a noninvasive needle placed away from the true acupuncture points. The primary outcome was live birth, defined as the delivery of 1 or more living infants at greater than 20 weeks' gestation or birth weight of at least 400 g. Among 848 randomized women, 24 withdrew consent, 824 were included in the study (mean [SD] age, 35.4 [4.3] years); 371 [45.0%] had undergone more than 2 previous IVF cycles), 607 proceeded to an embryo transfer, and 809 (98.2%) had data available on live birth outcomes. Live births occurred among 74 of 405 women (18.3%) receiving acupuncture compared with 72 of 404 women (17.8%) receiving sham control (risk difference, 0.5% [95% CI, -4.9% to 5.8%]; relative risk, 1.02 [95% CI, 0.76 to 1.38]). Among women undergoing IVF, administration of acupuncture vs sham acupuncture at the time of ovarian stimulation and embryo transfer resulted in no significant difference in live birth rates. These findings do not support the use of acupuncture to improve the rate of live births among women undergoing IVF. anzctr.org.au Identifier: ACTRN12611000226909.

Molecular profiling and commercial predication assays in ovarian cancer: still not ready for prime time?

PubMed

Kohn, Elise C

2014-01-01

Short of early detection to allow curative primary intervention, the other major barrier to further success in treatment of ovarian cancers is matching the best treatment to the proper ovarian cancer type and to the individual patient. There are several decades of experience applying in vitro chemoresponse testing for solid tumors including ovarian cancer. This concept, first described in 1979, has yet to receive level one evidence supporting its application, despite the testing of numerous assays commercially as well as in academic centers and its use for tens of thousands of patients at a significant cost. The approach-rather than undergoing rigorous scientific examination-is now being muddied by the development of commercial molecular profiling assays from which treatment suggestions are provided. Molecular profiling as a research tool has added value to our understanding and treatment of patients with ovarian cancer. Morphologic and histochemical characterizations coupled now with increasing knowledge of ovarian cancer type-specific molecular patterns is improving our ability to properly diagnosis ovarian cancer type and thus guide therapy. With the exception of the role of germ-line and possibly somatic BRCA1 and BRCA2 mutations and their true predictiveness for probable response to poly(ADP-ribose) polymerase inhibition, molecular typing and profiling has yet to identify druggable molecular targets in ovarian cancer. Its use should be continued as a research and learning tool, and its results should be subjected to clinical trial validation. For very different reasons, neither chemoresponse assays nor molecular profiling are ready for prime time, yet.

To determine the long-term outcomes of patients with an isolated ovarian recurrence after fertility sparing surgery (FSS) for epithelial ovarian cancer (EOC) and to evaluate the recurrence rates (and location) according to the new 2014 International Federation of Gynecology and Obstetrics (FIGO) staging system. Retrospective multicenter study. Teams having reported recurrence after FSS for EOC. Four series comprising 545 patients undergoing FSS and 63 (12%) recurrences. FSS (salpingo-oophorectomy for a majority of cases) for EOC. Recurrences rates and characteristics of recurrent disease. Among 63 recurrent patients, 24 (38%) recurrences were isolated on the spared ovary, and 39 (62%) arose at an extraovarian site. Among the patients with an isolated ovarian recurrence, three patients died after a median follow-up period of 186 months (range: 28-294 months). Among the patients with recurrent extraovarian disease, 24 died and 7 were alive with persistent disease after a median follow-up period of 34 months (range: 3-231 months). The overall rate of isolated ovarian and extrapelvic recurrences was higher for grade 3 tumors (compared with grades 1/2). The long-term survival of patients with an isolated ovarian recurrence after FSS for EOC remains favorable. The prognosis of patients with an extraovarian recurrence is poor compared with those who have an isolated recurrent ovarian tumor. Grade 3 tumors (compared to grades 1/2) give rise to a higher rate of extraovarian recurrences. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc.

Examination of diagnostic features in multiphoton microscopy and optical coherence tomography images of ovarian tumorigenesis in a mouse model

NASA Astrophysics Data System (ADS)

Watson, Jennifer M.

Ovarian cancer is a deadly disease owing to the non-specific symptoms and suspected rapid progression, leading to frequent late stage detection and poor prognosis. Medical imaging methods such as CT, MRI and ultrasound as well as serum testing for cancer markers have had extremely poor performance for early disease detection. Due to the poor performance of available screening methods, and the impracticality and ineffectiveness of taking tissue biopsies from the ovary, women at high risk for developing ovarian cancer are often advised to undergo prophylactic salpingo-oophorectomy. This surgery results in many side effects and is most often unnecessary since only a fraction of high risk women go on to develop ovarian cancer. Better understanding of the early development of ovarian cancer and characterization of morphological changes associated with early disease could lead to the development of an effective screening test for women at high risk. Optical imaging methods including optical coherence tomography (OCT) and multiphoton microscopy (MPM) are excellent tools for studying disease progression owing to the high resolution and depth sectioning capabilities. Further, these techniques are excellent for optical biopsy because they can image in situ non-destructively. In the studies described in this dissertation OCT and MPM are used to identify cellular and tissue morphological changes associated with early tumor development in a mouse model of ovarian cancer. This work is organized into three specific aims. The first aim is to use the images from the MPM phenomenon of second harmonic generation to quantitatively examine the morphological differences in collagen structure in normal mouse ovarian tissue and mouse ovarian tumors. The second aim is to examine the differences in endogenous two-photon excited fluorescence in normal mouse ovarian tissue and mouse ovarian tumors. The third and final aim is to identify changes in ovarian microstructure resulting from early disease development by imaging animals in vivo at three time points during a long-term survival study.

We applied hydrophilic interaction liquid chromatography coupled with tandem mass spectrometry to the quantitative analysis of serum from 58 women, including ovarian cancer patients, ovarian benign tumor patients, and healthy controls. All of these ovarian cancer and ovarian benign tumor patients have elevated cancer antigen 125, which makes them clinically difficult to differentiate the malignant from the benign. All of the 16 endogenous carbohydrates were quantitatively detected in the human sera, of which, eight endogenous carbohydrates were significantly different (P-value < 0.05) between the ovarian cancer and healthy control. According to the receiver operating characteristic curve analysis, arabitol was the most potentially specific biomarker for discriminating ovarian cancer from healthy control, having an area under the curve of 0.911. A panel of metabolite markers composed of maltose, maltotriose, raffinose, and mannitol was selected, which was able to discriminate the ovarian cancer from the benign ovarian tumor counterparts, with an area under concentration-time curve value of 0.832. Endogenous carbohydrates in the expanded metabolomics approach after the global metabolic profiling are characterized and are potential biomarkers for the early diagnosis of ovarian cancer. © 2015 WILEY-VCH Verlag GmbH & Co.

Because current imaging techniques (ultrasound, CT, MRI, PET) are not capable of detecting ovarian cancer early, most diagnoses occur in later stages (III/IV). Thus many women are not correctly diagnosed until the cancer becomes widely metastatic. On the other hand, while the majority of women with a detectable ultrasound abnormality do not harbor a cancer, they all undergo unnecessary oophorectomy. Hence, new imaging techniques that can provide functional and molecular contrasts are needed for improving the specificity of ovarian cancer detection and characterization. One such technique is photoacoustic imaging, which has great potential to reveal early tumor angiogenesis through intrinsic optical absorption contrast from hemoglobin or extrinsic contrast from conjugated agents binding to appropriate molecular receptors. To better understand the cancer disease process of ovarian tissue using photoacoustic imaging, it is necessary to first characterize the properties of normal ovarian tissue. We have imaged ex-vivo ovarian tissue using a 3D co-registered ultrasound and photoacoustic imaging system. The system is capable of volumetric imaging by means of electronic focusing. Detecting and visualizing small features from multiple viewing angles is possible without the need for any mechanical movement. The results show strong optical absorption from vasculature, especially highly vascularized corpora lutea, and low absorption from follicles. We will present correlation of photoacoustic images from animals with histology. Potential application of this technology would be the noninvasive imaging of the ovaries for screening or diagnostic purposes.

The aim of this study was to evaluate whether body weight changes in patients undergoing chemotherapy for epithelial ovarian cancer (EOC) influence progression-free survival (PFS) and overall survival (OS). An analysis of 190 patients diagnosed with ovarian cancer after first-line chemotherapy was conducted. Changes in body weight were assessed by comparing measurements at baseline to those of the third and sixth cycles of chemotherapy. PFS and OS were calculated with the Kaplan-Meier method and multivariate Cox model. Significant reduction in body weight in advanced EOC was observed with no changes in early EOC. Significant differences in PFS were observed in advanced EOC patients that lost more than 5 % of their body weight (6 months), maintained weight (13 months), or gained more than 5 % of their body weight (15 months). Similarly, significant differences in OS were noted in advanced EOC at the following time points: 24.3, 42.4, and 66.2 months. No effect was reported for early EOC patients. The multivariate Cox analysis showed significant body weight changes from the first to the sixth chemotherapy cycle for PFS (HR = 0.97; 95 % CI 0.95-0.99) and OS (HR = 0.94; 95 % CI 0.91-0.97) as well as from the first to the third chemotherapy cycle for OS (HR = 0.93; 95 % CI 0.88-0.98). Body weight changes can be recognized as a prognostic factor for PFS and OS in advanced EOC patients undergoing chemotherapy. Weight loss is associated with poorer survival while weight gain improved outcomes.

To test the applicability of the Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) and Memorial Sloan Kettering (MSK) criteria in predicting complete cytoreduction (CC) in patients undergoing secondary cytoreductive surgery (SCS) for recurrent ovarian cancer (ROC). Data of consecutive patients undergoing SCS were reviewed. The Arbeitsgemeinschaft Gynäkologische Onkologie OVARian cancer study group (AGO-OVAR) and MSK criteria were retrospectively applied. Nomograms, based on AGO criteria, MSK criteria and both AGO and MSK criteria were built in order to assess the probability to achieve CC at SCS. Overall, 194 patients met the inclusion criteria. CC was achieved in 161 (82.9%) patients. According to the AGO-OVAR criteria, we observed that CC was achieved in 87.0% of patients with positive AGO score. However, 45 out of 71 (63.4%) patients who did not fulfilled the AGO score had CC. Similarly, CC was achieved in 87.1%, 61.9% and 66.7% of patients for whom SCS was recommended, had to be considered and was not recommended, respectively. In order to evaluate the predictive value of the AGO-OVAR and MSK criteria we built 2 separate nomograms (c-index: 0.5900 and 0.5989, respectively) to test the probability to achieve CC at SCS. Additionally, we built a nomogram using both the aforementioned criteria (c-index: 0.5857). The AGO and MSK criteria help identifying patients deserving SCS. However, these criteria might be strict, thus prohibiting a beneficial treatment in patients who do not met these criteria. Further studies are needed to clarify factors predicting CC at SCS.

Objective: To investigate the effect of ovarian stimulation on the expression of EG-VEGF mRNA and protein in peri-implantation endometrium in women undergoing IVF and its relation with endometrial receptivity (ER). Design: Prospective laboratory study. Setting: University hospital. Patients: Eighteen women in stimulated cycles (SC) as study subjects and 18 women in natural cycles (NC) as controls. Women in SC group were classified with two subgroups, high ovarian response (SC1, n=9) with peak serum E2>5,000 pg/mL and moderate ovarian response (SC2, n=9) with peak serum E2 1,000-5,000 pg/mL. Intervention(s): Endometrial biopsies were collected 6 days after ovulation in NC or after oocyte retrieval in SC. Main outcome measure(s): Endometrium histological dating was observed with HE staining. EG-VEGF mRNA expression levels determined by real-time polymerase chain reaction analysis, and protein levels by immunohistochemistry. Results: All endometrial samples were in the secretory phase. The endometrial development in SC1 was 1 to 2 days advanced to NC, and with dyssynchrony between glandular and stromal tissue. Immunohistochemistry analysis showed that EG-VEGF protein was predominantly expressed in the glandular epithelial cells and endothelial cells of vessels, and also presented in the stroma. The image analysis confirmed that both the gland and stroma of endometrium in SC1 had a significantly lower EG-VEGF protein expression than that in SC2 and NC endometrium. Moreover, EG-VEGF mRNA levels were significantly lower in SC1 than in NC. Both EG-VEGF protein and mRNA levels had no significant difference between SC2 and NC. Conclusion: Decreased expression of EG-VEGF in the peri-implantation is associated with high ovarian response, which may account for the impaired ER and lower implantation rate in IVF cycles.

Introduction Ovarian cancer (OC) is associated with non-specific symptoms such as bloating, making accurate diagnosis challenging: only 1 in 3 women with OC presents through primary care referral. National Institute for Health and Care Excellence guidelines recommends sequential testing with CA125 and routine ultrasound in primary care. However, these diagnostic tests have limited sensitivity or specificity. Improving accurate triage in women with vague symptoms is likely to improve mortality by streamlining referral and care pathways. The Refining Ovarian Cancer Test Accuracy Scores (ROCkeTS; HTA 13/13/01) project will derive and validate new tests/risk prediction models that estimate the probability of having OC in women with symptoms. This protocol refers to the prospective study only (phase III). Methods and analysis ROCkeTS comprises four parallel phases. The full ROCkeTS protocol can be found at http://www.birmingham.ac.uk/ROCKETS. Phase III is a prospective test accuracy study. The study will recruit 2450 patients from 15 UK sites. Recruited patients complete symptom and anxiety questionnaires, donate a serum sample and undergo ultrasound scored as per International Ovarian Tumour Analysis (IOTA) criteria. Recruitment is at rapid access clinics, emergency departments and elective clinics. Models to be evaluated include those based on ultrasound derived by the IOTA group and novel models derived from analysis of existing data sets. Estimates of sensitivity, specificity, c-statistic (area under receiver operating curve), positive predictive value and negative predictive value of diagnostic tests are evaluated and a calibration plot for models will be presented. ROCkeTS has received ethical approval from the NHS West Midlands REC (14/WM/1241) and is registered on the controlled trials website (ISRCTN17160843) and the National Institute of Health Research Cancer and Reproductive Health portfolios.

To assess the influence of infertility and fertility drugs on risk of ovarian tumors. Case-control study (Mayo Clinic Ovarian Cancer Study). Ongoing academic study of ovarian cancer. A total of 1,900 women (1,028 with ovarian tumors and 872 controls, frequency matched on age and region of residence) who had provided complete information in a self-report questionnaire about history of infertility and fertility drug use. None. Effect of infertility history, use of fertility drugs and oral contraception, and gravidity on the risk of ovarian tumor development, after controlling for potential confounders. Among women who had a history of infertility, use of fertility drugs was reported by 44 (24%) of 182 controls and 38 (17%) of 226 cases. Infertile women who used fertility drugs were not at increased risk of developing ovarian tumors compared with infertile women who did not use fertility drugs; the adjusted odds ratio was 0.64 (95% CI, 0.37, 1.11). The findings were similar when stratified by gravidity and when analyzed separately for borderline versus invasive tumors. We found no statistically significant association between fertility drug use and risk of ovarian tumors. Further larger, prospective studies are needed to confirm this observation.

We investigated the effects of the gonadotropin-releasing hormone (GnRH) agonist triptorelin as well the GnRH antagonist cetrorelix those of on the viability and steroidogenesis in human granulosa luteinized (hGL) cell cultures. The hGL cells were obtained from 34 women undergoing ovarian stimulation for IVF treatment. The cells were cultured for 48 h with or without 1 nM or 3 nM of cetrorelix or triptorelin in serum-free media. The cell viability was evaluated by the MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide] assay. The concentrations of estradiol and progesterone in culture supernatants were measured by ELISA. Treatment with triptorelin slightly increased cell viability, whereas treatment with 3 nM cetrorelix led to a significant decrease. Estradiol concentrations were reduced with 3 nM triptorelin. Cultures treated with high-dose of either cetrorelix or triptorelin tended to secrete less progesterone than controls. Cetrorelix significantly reduces the viability of hGL cells. Triptorelin and cetrorelix may have minor effects on steroidogenesis. These results suggest that GnRH analogues may influence ovarian functions.

Melatonin, the major hormone of the pineal gland, has antigonadotrophic activity in many mammals and may also be involved in human reproduction. Melatonin suppresses steroidogenesis by ovarian granulosa and luteal cells in vitro. To determine if melatonin is present in the human ovary, preovulatory follicular fluids (n = 32) from 15 women were assayed for melatonin by RIA after solvent extraction. The fluids were obtained by laparoscopy or sonographically controlled follicular puncture from infertile women undergoing in vitro fertilization and embryo transfer. All patients had received clomiphene citrate, human menopausal gonadotropin, and hCG to stimulate follicle formation. Blood samples were obtained by venipuncture 30 min or less after follicular aspiration. All of the follicular fluids contained melatonin, in concentrations (35.6 plus or minus 4.8 (plus or minus SEM) pg/mL) substantially higher than those in the corresponding serum (10.0 plus or minus 1.4 pg/mL). A positive correlation was found between follicular fluid and serum melatonin levels in each woman (r = 0.770; P less than 0.001). These observations indicate that preovulatory follicles contain substantial amounts of melatonin that may affect ovarian steroidogenesis.

Epidemiological studies that have investigated the association between coffee, tea and caffeine consumption and ovarian cancer risk have produced conflicting results. Furthermore, only few studies have examined the role of coffee and tea consumption separately for borderline ovarian tumors. By use of data from a large Danish population-based case-control study, we examined the risk of ovarian tumors associated with coffee, tea, and caffeine consumption with a particular focus on characterizing risks by tumor behavior and histology. From 1995 through 1999, we included 267 women with ovarian cancer, 115 women with borderline ovarian tumors and 911 randomly selected control women. All women completed a beverage frequency questionnaire with detailed information on coffee and tea consumption. Analyses were performed using multiple logistic regression models. Both coffee (OR = 0.90; 95% CI 0.84-0.97 per cup/day) and total caffeine consumption from coffee and tea combined (OR = 0.93; 95% CI 0.88-0.98 per 100 mg/day) decreased the risk of ovarian cancer. These associations were significant only for the serous and "other" subtypes of ovarian cancer. No relation between tea consumption and ovarian cancer risk was observed. The risk estimates for borderline ovarian tumors resembled those observed for ovarian cancer, but did not reach statistical significance. Our results indicate that coffee consumption and total caffeine consumption from coffee and tea combined is associated with a modest decreased risk of ovarian cancer. However, more biological studies are needed to identify bioactive chemical compounds in coffee that potentially could affect ovarian cancer development.

Objective To evaluate in vitro maturation (IVM) in sub-fertile women with polycystic ovarian syndrome (PCOS) undergoing in vitro fertilisation (IVF), by comparing outcomes with a control group of non-PCOS. Study design A search strategy was developed for PubMed and studies reporting rates of the following outcomes (live birth; clinical pregnancy; implantation; cycle cancellation; oocyte maturation; oocyte fertilization; miscarriage) between patients with PCOS, PCO and controls undergoing IVM were deemed eligible. The review was conducted in accordance to the PRISMA guidelines and included studies quality was assessed through the Newcastle-Ottawa Quality scale. ORs with their corresponding 95% CIs were calculated for the main analysis and subgroup analyses were performed for PCOS cases vs. controls and PCOS vs. PCO cases. Alternative analyses were performed for live birth and clinical pregnancy, based on cycles and on women. Subgroup analyses for FSH stimulation, hCG priming and type of procedure (IVF/ICSI) were undertaken for all meta-analyses encompassing at least four study arms. Random effects models were used to calculate pooled effect estimates. Results Eleven studies were identified. A total of 268 PCOS patients (328 cycles), 100 PCO patients (110 cycles) and 440 controls (480 cycles) were included in the meta-analysis. A borderline trend towards higher birth rates among PCOS patients emerged (pooled OR = 1.74, 95%CI: 0.99–3.04) mainly reflected at the subgroup analysis vs. controls. Clinical pregnancy (pooled OR = 2.37, 95%CI: 1.53–3.68) and implantation rates (pooled OR = 1.73, 95%CI: 1.06–2.81) were higher, while cancellation rates lower (pooled OR = 0.18, 95%CI: 0.06-0.47) among PCOS vs. non-PCOS subjects; maturation and miscarriage rates did not differ between groups, while a borderline trend towards lower fertilization rates among PCOS patients was observed. Conclusion The present meta-analysis provides preliminary evidence on the effectiveness of IVM as a treatment option when offered in sub-fertile PCOS women, as the latter present at least as high outcome rates as those in non-PCOS.

To estimate rates of ovarian aging in polycystic ovary syndrome (PCOS) subjects versus a community control population. Longitudinal. Tertiary academic center. PCOS subjects diagnosed according to the 2004 Rotterdam criteria were systematically enrolled in a PCOS cohort study. The comparison control subjects were from the Ovarian Aging study, a prospective longitudinal study of ovarian aging in healthy women with regular menstrual cycles. Clinical data collection over two study visits. Antral follicle count (AFC), ovarian volume (OV), and antimüllerian hormone level (AMH). PCOS subjects were found to have higher baseline values for all ovarian reserve markers compared with control subjects. Univariate models indicated that, compared with control subjects, PCOS patients experienced significantly faster rates of decline for both AFC and AMH. Change in OV did not differ significantly. To account for potential confounder effects, multiple analysis of covariance models were evaluated for the best fit, considering age, body mass index, and baseline ovarian reserve markers. Adjusted models demonstrated that PCOS patients do not experience a significant difference in AFC decline compared with control subjects, but they do experience a faster rate of decline in AMH (P<.01) and slower rate of decline in OV (P<.01). Ovarian aging in PCOS is characterized by a more rapid decline in AMH and a slower decline in OV compared with control subjects. Copyright © 2017 American Society for Reproductive Medicine.

To evaluate the influence of ovarian follicular dominance on the outcome of oocyte in-vitro maturation. This retrospective cohort study included 21 patients with polycystic ovaries or polycystic ovary syndrome (Rotterdam criteria, 2004) subjected to 24 invitro maturation (IVM) cycles between October 2015 and January 2017. Patients undergoing IVM received minimal gonadotropin stimulation starting on day 2 or 3 of the cycle; ovum pick-up typically occurred on days 6 to 8. No hCG-trigger shot was given. Following 30h of IVM, mature oocytes were inseminated by ICSI and the resulting embryos cultured up to the blastocyst stage. Ovarian follicular dominance was observed in nine of the 24 IVM cycles. Oocyte IVM yielded an overall maturation rate of 69.3±23.8%, and no difference was observed when the groups with or without a dominant follicle were assessed independently. The rates of fertilization and usable blastocysts per fertilized oocyte, mature oocyte (Metaphase II) or cumulus-oocyte-complex were nearly three times higher (28.7±22.5%) in the group without ovarian follicular dominance. No differences were found in the clinical pregnancy rates attained by the individuals with or without a dominant follicle after 21 vitrified-warmed blastocyst transfer cycles. Occurrence of ovarian follicular dominance during hormonal stimulation for in-vitro maturation negatively impacted embryological outcomes. Strategies devised to limit the appearance of ovarian follicular dominance must be further explored.

To compare the outcomes of protocols for ovarian stimulation with recombinant hCG microdose, with GnRH agonists and antagonists for pituitary suppression. Prospective nonrandomized clinical trial. A private assisted reproduction center. We studied 182 patients undergoing intracytoplasmic sperm injection (ICSI) cycles, allocated into two groups: GnRH agonist group, in which patients received a GnRH agonist (n = 73), and a GnRH antagonist group, in which patients were administered a GnRH antagonist for pituitary suppression (n = 109). Pituitary suppression with GnRH agonist or GnRH antagonist. Ovarian stimulation carried out with recombinant FSH and supplemented with recombinant hCG microdose. Total dose of recombinant FSH and recombinant hCG administered; E(2) concentrations and endometrial width on the day of hCG trigger; number of follicles aspirated, oocytes and mature oocytes retrieved; fertilization, pregnancy (PR), implantation, and miscarriage rates. The total dose of recombinant FSH and recombinant hCG administered were similar between groups, as were the E(2) concentrations and endometrial width. The number of follicles aspirated, oocytes, and metaphase II oocytes collected were also comparable. There were no statistically significant differences in fertilization, PR, implantation, and miscarriage rates in the GnRH agonist and GnRH antagonist groups. When using recombinant hCG microdose supplementation for controlled ovarian stimulation (COS), there are no differences in laboratory or clinical outcomes with the use of either GnRH antagonist or agonist for pituitary suppression.

To evaluate the hormonal profile in three breast cancer patients who underwent controlled ovarian stimulation in the presence of the aromatase inhibitor letrozole. In IVF University referral center, a case series of three breast cancer patients who underwent controlled ovarian stimulation (COS) with recombinant FSH and letrozole were investigated. Ovulation was induced with hCG (case No. 1) or with GnRH agonist (case No. 2-3). The primary outcome of our study was the detection of progesterone levels in the luteal phase. Very high progesterone values (mean 186.6 ± 43.6 ng/mL) during the luteal phase were recorded in all three cases. High progesterone levels can be related to the use of letrozole independently of the most commonly used trigger regimen. Although progesterone has long been considered a protective factor against breast cancer, several studies have demonstrated that progesterone could expand a transformation-sensitive stem cell population in the mammary glands. The estrogen negative feedback effect on the hypothalamus-pituitary axis and the disruption of steroid biosynthesis and could represent an intriguing reason behind this phenomenon. Our results highlight the need to evaluate further the increase in progesterone levels in the luteal phase in women with breast cancer undergoing COS with letrozole.

Objective: To evaluate the impact of luteal phase support with vaginal progesterone on pregnancy rates in the intrauterine insemination (IUI) cycles, stimulated with clomiphene citrate and human menopausal gonadotropin (hMG), in sub fertile couples. Materials and methods: This prospective, randomized, double blind study was performed in a tertiary infertility center from March 2011 to January 2012. It consisted of 253 sub fertile couples undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with clomiphene citrate (100 mg) and hMG (75 IU) in preparation for the IUI cycle. Study group (n = 127) received luteal phase support in the form of vaginal progesterone (400 mg twice a day), and control group (n = 126) received placebo. Clinical pregnancy and abortion rates were assessed and compared between the two groups. Results: The clinical pregnancy rate was not significantly higher for supported cycles than that for the unsupported ones (15.75% vs. 12.69%, p = 0.3). The abortion rate in the patients with progesterone luteal support compared to placebo group was not statistically different (10% vs. 18.75%, p = 0.45). Conclusion: It seems that luteal phase support with vaginal progesterone was not enhanced the success of IUI cycles outcomes, when clomiphene citrate and hMG were used for ovulation stimulation.

BACKGROUND The aim of this study was to evaluate the influence of combined general/epidural anesthesia (GEA) on hemodynamics, respiratory function and stress hormone levels in patients with ovarian neoplasm undergoing laparoscopy. MATERIAL AND METHODS A total of 177 patients with ovarian neoplasm (screened by inclusion/exclusion criteria) receiving laparoscopy were divided into groups G (general anesthesia alone), L1.0 (GEA with 1.0% lidocaine), and L1.5 (GEA with 1.5% lidocaine). Hemodynamics, respiratory parameters and stress hormone levels in the 3 groups were recorded and analyzed. RESULTS Hemodynamic indexes and PaO2/PaCO2 in group L1.0 showed no differences at each time point (all P>0.05). At the end of anesthesia tracheal intubation (T1), 10 min after pneumoperitoneum (T2) and the end of anesthesia tracheal extubation (T3), there were significant differences in hemodynamic indexes, respiratory parameters, epinephrine (E), and noradrenalin (NE) of group G/L1.5, compared with before anesthesia induction (T0) (all P<0.05). Compared with group G, there were big differences in dosage of anesthetics (sufentanil, vecuronium, and propofol) and pharmaceutic adjuvants (ephedrine, atropine, and nitroglycerin), postoperative recovery time, extubation time, and incidence of agitation in group L1.0/L1.5 (all P<0.05). CONCLUSIONS GEA can improve the quality and efficiency in laparoscopy for ovarian neoplasm, with the advantages of reduced anesthetics dosage, satisfactory postoperative analgesia, maintained hemodynamic stability, excellent uterine relaxation, and reduced time of anesthesia induction, surgery, recovery, and extubation. In addition, compared with group L1.5, group L1.0 was more secure and worthy of clinical promotion in laparoscopy.

Women with an increased lifetime risk of ovarian cancer are advised to undergo risk-reducing salpingo-oophorectomy (RRSO) to reduce risk of adnexal cancer. We investigated the uptake of RRSO and evaluated the influence of personal medical history of (breast) cancer, risk-reducing mastectomy (RRM) and family history of ovarian and/or breast cancer on the RRSO decision. This single center retrospective observational cohort study was performed in a tertiary multidisciplinary clinic for hereditary cancer of the University Medical Centre Utrecht, The Netherlands. Women ≥35 years old with an estimated lifetime risk of ovarian cancer ≥10%, who had completed childbearing, were eligible for RRSO. Uptake and timing of RRSO were analyzed. Influence of personal medical history and family history on RRSO decision making, were evaluated with logistic regression. The study population consisted of 218 women (45.0% BRCA1 mutation carrier, 28.0% BRCA2 mutation carrier, 27.0% with familial susceptibility) with 87.2% RRSO uptake. The median age at RRSO was 44.5 (range 28-73) years. Of the women undergoing RRSO, 78.3% needed ≤3 consultations to reach this decision. Multivariable analysis showed a significant difference in RRSO uptake for women with a history of RRM [OR 3.66 95% CI (1.12-11.98)], but no significant difference in women with a history of breast cancer [OR 1.38 95% CI (0.50-3.79)], nor with a family history of ovarian and/or breast cancer [OR 1.10 95% CI (0.44-2.76)]. We conclude that RRSO counseling, without the alternative of screening, is effective. The uptake is increased in women with a history of RRM.

Purpose We have previously reported an approach to ovarian stimulation for the purpose of fertility preservation (FP) in women with breast cancer via embryo freezing with the concurrent use of letrozole. The aim of this study was to provide the pregnancy and FP outcomes when embryos generated with the same protocol are used. Patients and Methods In all, 131 women with stage ≤ 3 breast cancer underwent ovarian stimulation and received concurrent letrozole 5 mg per day before receiving adjuvant chemotherapy and cryopreserving embryos. Results Thirty-three of the 131 women underwent 40 attempts to transfer embryos to their own uterus (n = 18) or via the use of a gestational carrier (n = 22) at a mean age of 41.5 ± 4.3 years with a median 5.25 years after embryo cryopreservation. The overall live birth rate per embryo transfer was similar to the US national mean among infertile women of a similar age undergoing in vitro fertilization–embryo transfer (45.0 v 38.2; P = .2). Seven (38.8%) of the 18 pregnancies were twins with no higher-order pregnancies being encountered. No fetal anomalies or malformations were reported in 25 children after a mean follow-up of 40.4 ± 26.4 months. Seventeen of the 33 women attempting pregnancy had at least one child, translating into an FP rate of 51.5% per attempting woman. Conclusion Embryo cryopreservation after ovarian stimulation with the letrozole and follicle-stimulating hormone protocol preserves fertility in women with breast cancer and results in pregnancy rates comparable to those expected in a noncancer population undergoing in vitro fertilization.

Octogenarians with ovarian cancer limited to the abdomen may not be willing or able to undergo systemic chemotherapy. Low-dose pressurized intraperitoneal aerosol chemotherapy (PIPAC) with cisplatin and doxorubicin is a form of intra-abdominal chemotherapy which can be applied repeatedly and potentially prevents from the systemic side-effects of chemotherapy. We present the case of an 84-year-old woman with laparoscopically and histologically confirmed ovarian cancer who refused to undergo systemic chemotherapy. She was treated with eight courses q 28-104 days of low-dose PIPAC with cisplatin at 7.5 mg/m(2) and doxorubicin at 1.5 mg/m(2) at 12 mmHg and 37 °C for 30 min. Objective tumor response was noted, defined as tumor regression on histology, and stable disease noted by peritoneal carcinomatosis index on repeated video-laparoscopy and abdominal computed tomographic scan. The treatment was well-tolerated with no Common Terminology Criteria for Adverse Events (CTCAE) CTCAE >2. With a follow-up of 15 months, the patient is alive and clinically stable. The quality of life measured by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 demonstrated improvement over 5-6 months (global physical score, global health score, global quality of live) without cumulative increase of gastrointestinal toxicity. Low-dose PIPAC is a new form of intraperitoneal chemotherapy which may be applied repeatedly in octogenarian patients. PIPAC may be an alternative and well-tolerated treatment for selected octogenarian patients with ovarian cancer limited to the abdomen who cannot be treated with systemic chemotherapy.

In this study, our objective was to evaluating the value of serum zinc levels as an etiologic and prognostic marker in patients with polycystic ovarian syndrome. We conducted a prospective study, including 53 women with polycystic ovarian syndrome and 33 healthy controls. We compared serum zinc levels, as well as clinical and metabolic features, of the cases. We also compared serum zinc levels between patients with polycystic ovarian syndrome with insulin resistance. Mean zinc levels were found to be significantly lower in patients with polycystic ovarian syndrome than healthy controls. Multiple logistic regression analysis of significant metabolic variables between polycystic ovarian syndrome and control groups (serum zinc level, body mass index, the ratio of triglyceride/high-density lipoprotein cholesterol, and homocysteine) revealed that zinc level was the most significant variable to predict polycystic ovarian syndrome. Mean serum zinc levels tended to be lower in patients with polycystic ovarian syndrome with impaired glucose tolerance than patients with normal glucose tolerance, but the difference was not statistically significant. In conclusion, zinc deficiency may play a role in the pathogenesis of polycystic ovarian syndrome and may be related with its long-term metabolic complications.

It is essential to determine the cut-off value of serum anti-Mullerian hormone (AMH) to predict the hyper response in assisted reproductive technology (ART). There are few studies mentioning the cut-off value for the hyper response in infertile women but not specifically for polycystic ovary syndrome (PCOS) and non-PCOS groups. With this in background, this study was conducted. To determine the cut-off value of serum AMH to predict the hyper response in women with PCOS and non-PCOS undergoing a controlled ovarian stimulation (COS) in ART. To compare the outcome of stimulation in PCOS and non-PCOS groups. All 246 women enrolled for Intra Cytoplasmic Sperm Injection (ICSI) fulfilling the selection criteria were recruited. On the day 3 of the cycle, the serum AMH, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), estradiol and antral follicle count (AFC) were measured. They underwent COS as per the unit protocol. They were divided into PCOS and non-PCOS groups as per the Rotterdam's criteria. The mean age, duration of infertility, Body Mass Index (BMI), Ovarian reserve markers and outcome of stimulation were compared. Using the Statistical Package for the Social Sciences version 16.0 software, the significant difference was measured by multivariate analysis, as well as a one-way analysis of variance with Tukey's post-hoc test was used. Among 246 women, 31.3% were in PCOS group, and 68.7% were in non-PCOS group. Comparison of PCOS and non-PCOS groups showed a significant difference in the age with the mean age being 29.2 and 31.5 years, respectively. The mean AMH and AFC were 2-fold higher in PCOS group. The mean number of follicles, oocytes retrieved, MII and oocytes fertilised were significantly higher in PCOS group. The pregnancy rate was 52.6% in PCOS and 30.9% in non-PCOS group. In the PCOS group, 22.1% had ovarian hyper stimulation syndrome (OHSS), and only 4.7% had OHSS in non-PCOS group ( P = 0.0005). Receiving Operator Curve (ROC) curve was plotted to predict the hyper response, which showed a cut-off value of 6.85 ng/ml with a sensitivity of 66.7% and a specificity of 68.7% for PCOS group and 4.85 ng/ml with a sensitivity of 85.7% and a specificity of 89.7% in non-PCOS group. The cut-off value of serum AMH to predict the hyper response in PCOS group is 6.85 ng/ml and in non-PCOS group is 4.85 ng/ml.

ABSTRACT Maternal nutritional restriction has been shown to induce impairments in a number of organ systems including the ovary. We have previously shown that maternal undernutrition induces fetal growth restriction and low birth weight, and results in an offspring ovarian phenotype characteristic of premature ovarian aging with reduced ovarian reserve. In the present study, we set out to investigate the underlying mechanisms that lead offspring of undernourished mothers to premature ovarian aging. Pregnant dams were randomized to 1) a standard diet throughout pregnancy and lactation (control), 2) a calorie-restricted (50% of control) diet during pregnancy, 3) a calorie-restricted (50% of control) diet during pregnancy and lactation, or 4) a calorie-restricted (50% of control) diet during lactation alone. The present study shows that early life undernutrition-induced reduction of adult ovarian follicles may be mediated by increased ovarian endoplasmic reticulum stress in a manner that increased follicular apoptosis but not autophagy. These changes were associated with a loss of ovarian vessel density and are consistent with an accelerated ovarian aging phenotype. Whether these changes are mediated specifically by a reduction in the local antioxidant environment is unclear, although our data suggest the possibility that ovarian melatonin may play a part in early life nutritional undernutrition and impaired offspring folliculogenesis.

The aim of the study was to ascertain if increasing body mass index (BMI) adversely affects ovarian reserve among infertile women of Asian origin undergoing in vitro fertilization (IVF). This prospective study on 183 women was carried out in the infertility clinic of All India Institute of Medical Sciences, New Delhi, India. Blood hormonal assay in all patients including follicle-stimulating hormone (FSH), luteinizing hormone (LH) and inhibin B was performed on day 2/3 of a spontaneous cycle. A transvaginal ultrasonographic examination on day 2-5 of the menstrual cycle was done for antral follicle count (AFC) and ovarian volume. A correlation between BMI and ovarian reserve parameters like FSH, LH, inhibin B, antral follicle count and ovarian volume was noted. Age was comparable in the three BMI groups. The mean duration of infertility was 8.38 years. Compared to the normal weight, the overweight and obese women had a statistically significantly low inhibin B (p < 0.0259). The AFC when taken together on both sides was not statistically significant between the groups; however, the overweight and obese women had a significantly low AFC (p < 0.0129) on the right side. Incorporating anti-mullerian hormone, a newer marker for ovarian reserve, may benefit these obese infertile women. Further work is required to elucidate the mechanisms underlying the effect of obesity on inhibin B as a marker of ovarian reserve in infertile women. The best marker to check the ovarian reserve is perhaps the woman's performance during an IVF cycle. However, considering the psychological and financial stress of the procedure, it may seem wise to consider counseling of obese women on their expected performance in the first cycle of IVF through such studies.

Endometriosis affects 2-50% of women at reproductive age. Surgery is an option for treatment, but there is no convincing evidence that it promotes a significant improvement in fertility. Also, the removal of ovarian endometrioma might lead to a reduction in the follicular reserve and response to stimulation. Therefore, the aim of this study was to evaluate the effect of previous ovarian surgery for endometriosis on the ovarian response in assisted reproduction treatment cycles and its pregnancy outcome. A total of 61 women, with primary infertility and previously having undergone ovarian surgery for endometriosis, who had received 74 IVF/intracytoplasmic sperm injection (ICSI) cycles, were studied (study group). A further 74 patients with primary infertility who underwent 77 IVF/ICSI cycles within#10; the same period of time, at the same clinic and without previous ovarian surgery or endometriosis were studied as a control group. Patients were matched for age and treatment performed. Patients 35 years with previous ovarian surgery needed more ampoules for ovulation induction (P = 0.017) and had fewer follicles and oocytes than women in the control group (P = 0.001). Duration of folliculogenesis was similar in both groups, as was fertilization rate. A total of 10 patients achieved pregnancy in the study group (34.5%) and 14 (48.3%) in the control group. Although a lower pregnancy rate was observed in patients who had undergone previous ovarian surgery, this difference was not statistically significant (P = 0.424). In conclusion, ovarian surgery for the treatment of endometriosis reduces the ovarian outcome in IVF/ICSI cycles in women >35 years old, and might also decrease pregnancy rates. Therefore, for infertile patients, non-surgical treatment might be a better option to avoid reduction of the ovarian response.

Oocyte cryopreservation solves the legal and ethical problems associated with the cryopreservation of embryos in patients undergoing in vitro fertilization procedures. Furthermore, it may also offer the possibility of extending the reproductive capability of young women with malignant diseases in cases where the treatment may compromise the ovarian reserve. Moreover, it may also offer alternatives for infertile patients who are subject to ovarian hyper-stimulation syndrome or premature ovarian faiLure or who require oocyte donation. The creation of banks for cryopreserved oocytes avoids the need for cycle synchronization or the formation of an over-supply of embryos destined for cryopreservation. If a Large number of oocytes is obtained it could possibly enable women and couples the opportunity to postpone childbirth according to their wishes. This paper reviews the revolution obtained by oocyte vitrification, reports on ethical issues and discusses the pros and cons of oocyte banking and its potential effects on society.

The Drosophila ovarian and testis stem cell niches: similar somatic stem cells and signals.

The stem cell niches at the apex of Drosophila ovaries and testes have been viewed as distinct in two major respects. While both contain germline stem cells, the testis niche also contains "cyst progenitor" stem cells, which divide to produce somatic cells that encase developing germ cells. Moreover, while both niches utilize BMP signaling, the testis niche requires a key JAK/STAT signal. We now show, by lineage marking, that the ovarian niche also contains a second type of stem cell. These "escort stem cells" morphologically resemble testis cyst progenitor cells and their daughters encase developing cysts before undergoing apoptosis at the time of follicle formation. In addition, we show that JAK/STAT signaling also plays a critical role in ovarian niche function, and acts within escort cells. These observations reveal striking similarities in the stem cell niches of male and female gonads, and suggest that they are largely governed by common mechanisms.

New advances in ovarian autotransplantation to restore fertility in cancer patients

PubMed Central

Human ovary autotransplantation is a promising option for fertility preservation of young women and girls undergoing gonadotoxic treatments for cancer or some autoimmune diseases. Although experimental, it resulted in at least 42 healthy babies worldwide. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature review was performed for all relevant full-text articles published in English from 1 January 2000 to 01 October 2015 in PubMed to explore the latest clinical and research advances of human ovary autotransplantation. Human ovary autotransplantation involves ovarian tissue extraction, freezing/thawing, and transplantation back into the same patient. Three major forms of human ovary autotransplantation exist including (a) transplantation of cortical ovarian tissue, (b) transplantation of whole ovary, and (c) transplantation of ovarian follicles (artificial ovary). According to the recent guidelines, human ovary autotransplantation is still considered experimental; however, it has unique advantages in comparison to other options of female fertility preservation. Human ovary autotransplantation (i) does not need prior ovarian stimulation, (ii) allows immediate initiation of cancer therapy, (iii) can restore both endocrine and reproductive ovarian functions, and (iv) may be the only fertility preservation option suitable for prepubertal girls or for young women with estrogen-sensitive malignancies. As any other fertility preservation option, human ovary autotransplantation has both advantages and disadvantages and may not be feasible for all cases. The major challenges facing this option are how to avoid the risk of reintroducing malignant cells and how to prolong the lifespan of ovarian transplant as well as how to improve artificial ovary results.

Several factors are known to influence ovarian response to rFSH stimulation such as age, antral follicle count (AFC), and basal FSH level, Mutation of allele Ser680Asn in FSHR gene was responsible to ovarian resistance toward exogenous FSH. The aim of this study is to develop a prediction model of ovarian response to COS in IVF. This study was a prospective cohort study. One hundred and thirteen women undergoing their first cycle of IVF in Yasmin IVF Clinic Jakarta were recruited to this study. Clinical datas included were age, BMI, and AFC. Basal FSH and E2 as well as serum AMH was measured from peripheral blood taken at second day of cycle. Bsr-1 enzyme is used to identify the polymorphism in exon 10 position 680 with RFLP technique. Three genotype polymorphism, Asn/Asn (255 bp ribbon), Asn/Ser (97 bp and 158 bp), and Ser/Ser (97 bp, 158 bp, and 255 bp). AFC has the highest predictor for ovarian response with AUC 0.922 (CI 95% 0.833-1.000). AMH also showed high predicting value (AUC 0.843 CI 95% 0.663-1.000). The multivariate analysis revealed combination of AFC, AMH, age, and basal FSH is a good model for ovarian response prediction (AUC=0.97). No significant relation between Asn/Asn, Asn/Ser, or Ser/Ser genotype FSHR polymorphism with ovarian response (p = 0.866) and total dose of rRSH (p = 0.08). This study showed that model combination of AFC, AMH, patient’s age and basal FSH are very good to predict number of mature oocytes.

To compare the hormonal-metabolic profiles and reproductive outcomes between women receiving metformin plus letrozole and women undergoing bilateral ovarian drilling in clomiphene citrate (CC)-resistant women with polycystic ovary syndrome (PCOS). In this randomized study, 146 patients were randomly allocated into group 1 (n = 73) who received metformin plus letrozole, and group 2 (n = 73) who underwent bilateral ovarian drilling. Comparison was done between the basal and after treatment biochemical values for each group, in addition reproductive outcomes after treatment were compared between both groups. There was significant reduction in testosterone (p ≤ 0.001), fasting insulin (p ≤ 0.001), and fasting glucose/fasting insulin ratio (p = 0.029) in metformin plus letrozole group, while there was significant reduction in FSH, LH and LH/FSH ratio in bilateral drilling group (p ≤ 0.001, 0.001 and 0.001). No significant difference in cycle regularity (p = 0.82), ovulation (p = 0.24), pregnancy rate (p = 0.32) and abortion rate (p = 0.51) between both groups. Both metformin plus letrozole and bilateral ovarian drilling are similarly effective as second-line strategies for the treatment of women with PCOS who do not conceive with CC.

Individualization of controlled ovarian stimulation in vitro fertilization using ovarian reserve markers.

Grisendi, Valentina; La Marca, Antonio

2017-06-01

In assisted reproduction technologies (ART) the controlled ovarian stimulation (COS) therapy is the starting point from which a good oocytes retrieval depends. Treatment individualization is based on ovarian response prediction, which largely depends on a woman's ovarian reserve. Anti-Müllerian hormone (AMH) and antral follicle count (AFC) are considered the most accurate and reliable markers of ovarian reserve. A literature search was carried out for studies that addressed the ability of AMH and AFC to predict poor and/or excessive ovarian response in IVF cycles. According to the predicted response to ovarian stimulation (poor- normal- or high-response) is today possible not only to personalize pre-treatment counseling with the couple, but also to individualize the ovarian stimulation protocol, choosing among GnRH-agonists or antagonists for endogenous follicle-stimulating hormone (FSH) suppression and formulating the FSH starting dose most adequate for the single patients. In this review we discuss how to choose the best COS therapy for the single patient, on the basis of the markers-guided ovarian response prediction.

Do cumulative live birth rates (CLBR) vary among women with different polycystic ovary syndrome (PCOS) phenotypes who undergo IVF/intracytoplasmic sperm injection (ICSI) treatment? In this retrospective cohort study, data from 567 patients undergoing an assisted reproductive technology (ART) cycle between January 2010 and December 2015 were collected. Demographical traits, cycle characteristics and clinical and laboratory data were analysed. After conventional ovarian stimulation using a gonadotrophin-releasing hormone antagonist protocol, the median number of oocytes retrieved ranged between 11 and 13.5 and did not differ significantly among the studied groups. Live birth rate (LBR) after fresh embryo transfer and CLBR after transfer of all fresh and vitrified embryos were significantly lower in women with hyperandrogenic PCOS phenotypes A (LBR 16.7%, CLBR 25.8%) and C (LBR 18.5%, CLBR 27.8%) compared with women with normoandrogenic PCOS phenotype D (LBR 33.7%, CLBR 48%) (P-value for LBR 0.01 and 0.03, respectively; P-value for CLBR 0.002 and 0.01, respectively) and controls with a polycystic ovarian morphology (LBR 37.1%, CLBR 53.3%) (P-value for LBR 0.002 and 0.01, respectively; P-value for CLBR <0.001 and 0.001, respectively). Multivariate regression analysis indicated that after adjustment for relevant confounders, PCOS phenotype was an independent predictor for CLBR. Hyperandrogenic PCOS phenotypes confer significantly lower CLBR compared with their normoandrogenic counterparts. These findings may imply the need for adapted counselling and tailored approaches when treating PCOS patients with hyperandrogenism who require ART. Copyright © 2018 Reproductive Healthcare Ltd.

BACKGROUND Increasing the success rate of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) is a duty of clinicians that has made many seek a variety of protocols. This study was undertaken to use a liquid chromatography-mass spectrometry (LC-MS) to define the alterations of follicular fluid (FF) lipid metabolites in patients undergoing progestin-primed ovarian stimulation (PPOS) compared with short-term protocol, revealing potential correlations between the differentially expressed lipids and ameliorative clinical outcomes. MATERIAL AND METHODS Ninety-three infertile women undergoing IVF/ICSI treatment with PPOS (n=62) or a short-term protocol (n=31) were prospectively enrolled in a randomized controlled trial. FF samples were obtained from dominant follicles at the time of oocyte retrieval. Lipid metabolism profiles were analyzed using LC-MS. RESULTS Twelve lipids were found to be higher in patients treated with the PPOS protocol than in those receiving the short-term protocol, including triacylglycerols (TAG-34: 1+NH4, TAG-58: 0+NH4, TAG-64: 3+NH4, and TAG-64: 8+NH4), diacylglycerol DAG-38: 6+NH4, phosphatidylglycerols (PG-26: 0, PG-30: 2, and PG-40: 5), phosphatidylethanolamine PE-32: 2, lysophosphatidylethanolamine LPE-14: 1, lysophosphatidylinositol LPI-12: 0, and lysophosphatidylcholine LPC-16: 0. CONCLUSIONS Our data demonstrate that the PPOS protocol increases the levels of 12 lipids in FF, which reveals a strong association between the differentially elevated lipids and better IVF/ICSI outcomes.

Individualized controlled ovarian stimulation in expected poor-responders: an update.

Controlled ovarian stimulation with subsequent multi-follicular development continues to be a keystone in ART. Evidence supports an individualized approach to ovarian stimulation, usually involving combinations of ovarian reserve tests, body mass index and age to tailor the exogenous gonadotropin dose, and potentially adjuvant treatment aiming for high safety and a shortening of time to live birth. While stimulation and trigger concepts have been developed successfully in normo- and hyperresponder patients, the poor responder patient remains difficult to manage. However, recent advances in definition and classification of the expected poor ovarian responder patient might enable a more accurate and clinically useful interpretation of new treatment concepts in a more homogenous study population. In the present review, we discuss the classification of the expected poor ovarian responder patient as well as clinically useful measurements of efficacy for controlled ovarian stimulation, and finally, we discuss the evidence for clinical management of patients with expected poor ovarian response, including adjuvant treatments such as growth hormone, androgens, and LH activity.In conclusion, the best available evidence supports that the treatment of the expected poor ovarian response patient should be individualized in all steps of ART, including the choice of GnRH analogue, the gonadotropin type and dose, ovulation trigger, and the possible use of adjuvant therapies.

The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (P<0.05) than those in benign ovarian epithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

Most patients with early stage endometrial endometrioid adenocarcinoma (EEAC) are treated with hysterectomy and bilateral oophorectomy. But this surgical menopause leads to long-term sequelae for premenopausal women, especially for young women of childbearing age. This population-based study was to evaluate the safety of ovarian preservation in young women with stage I EEAC. Patients of age 50 or younger with stage I EEAC were explored from the Surveillance, Epidemiology and End Results program database during 2004 to 2013. Propensity score matching was used to randomize the data set and reduce the selection biases of doctors. Univariate analysis and multivariate cox proportional hazards model were utilized to estimate the safety of ovarian preservation. A total of 7183 patients were identified, and ovarian preservation was performed in 863 (12 %) patients. Compared with women treated with oophorectomy, patients with ovarian preservation significantly tend to be younger at diagnosis (P-value < 0.001) and more likely diagnosed as stage IA EEAC, to have better differentiated tumor tissues and smaller tumors, as well as less likely to undergo radiation and lymphadenectomy. 863 patients treated with oophorectomy were selected by propensity score matching. After propensity score matching, the differences of all characteristics between ovarian preservation and oophorectomy were not significant and potential confounders in the two groups decreased. In univariate analysis of matched population, ovarian preservation had no effect on overall (P-value=0.928) and cancer-specific (P-value=0.390) mortality. In propensityadjusted multivariate analysis, ovarian preservation was not significantly associated with overall (HR=0.69, 95%CI=0.41-1.68, P-value=0.611) and cancer-specific (HR=1.65, 95%CI=0.54-5.06, Pvalue= 0.379) survival. Ovarian preservation is safe for young women with stage I EEAC, which is not significantly associated with overall and cancer-specific mortality.

Objective To evaluate the influence of ovarian follicular dominance on the outcome of oocyte in-vitro maturation. Methods This retrospective cohort study included 21 patients with polycystic ovaries or polycystic ovary syndrome (Rotterdam criteria, 2004) subjected to 24 in-vitro maturation (IVM) cycles between October 2015 and January 2017. Patients undergoing IVM received minimal gonadotropin stimulation starting on day 2 or 3 of the cycle; ovum pick-up typically occurred on days 6 to 8. No hCG-trigger shot was given. Following 30h of IVM, mature oocytes were inseminated by ICSI and the resulting embryos cultured up to the blastocyst stage. Results Ovarian follicular dominance was observed in nine of the 24 IVM cycles. Oocyte IVM yielded an overall maturation rate of 69.3±23.8%, and no difference was observed when the groups with or without a dominant follicle were assessed independently. The rates of fertilization and usable blastocysts per fertilized oocyte, mature oocyte (Metaphase II) or cumulus-oocyte-complex were nearly three times higher (28.7±22.5%) in the group without ovarian follicular dominance. No differences were found in the clinical pregnancy rates attained by the individuals with or without a dominant follicle after 21 vitrified-warmed blastocyst transfer cycles. Conclusion Occurrence of ovarian follicular dominance during hormonal stimulation for in-vitro maturation negatively impacted embryological outcomes. Strategies devised to limit the appearance of ovarian follicular dominance must be further explored. PMID:29338139

Is the treatment with recombinant FSH (rFSH) plus recombinant LH (rLH) more effective than highly purified (HP)-hMG in terms of ongoing pregnancy rate (PR) in women ≥35 years of age undergoing intrauterine insemination (IUI) cycles? The ongoing PR was not significantly different in women treated with rFSH plus rLH or with HP-hMG. Although previous studies have shown beneficial effects of the addition of LH activity to FSH, in terms of PR in patients aged over 34 years having ovulation induction, no studies have compared two different gonadotrophin preparations containing LH activity in women ≥35 years of age in IUI cycles. A single-centre RCT was performed between May 2012 and September 2013 with 579 women ≥35 years of age undergoing IUI cycles. The patients were randomly assigned to one of the two groups, rFSH in combination with rLH group or HP-hMG (Meropur) group, by giving them a code number from a computer generated randomization list, in order of enrolment. The randomization visit took place on the first day of ovarian stimulation. Five hundred and seventy-nine patients with unexplained infertility or mild male factor undergoing IUI cycles were recruited in a university hospital setting. All women were enrolled in this study only for one cycle of treatment. Five hundred and seventy-nine cycles were included in the final analysis. Two hundred and ninety patients were treated with rFSH in combination with rLH and 289 patients were treated with HP-hMG. The ovarian stimulation cycle started on the third day of the menstrual cycle and the starting gonadotrophin doses used were 150 IU/day of rFSH plus 150 IU/day of rLH or 150 IU/day of HP-hMG. The drug dose was adjusted according to the individual follicular response. A single IUI per cycle was performed 34-36 h after hCG injection. The main outcome measures were ongoing PR and number of interrupted cycles for high risk of ovarian hyperstimulation syndrome (OHSS). Ongoing pregnancy rates were 48/290 (17.3%) in the recombinant group versus 35/289 (12.2%) in the HP-hMG group [(odds ratio (OR) 1.50, 95% CI 0.94-2.41, P = 0.09]. The number of interrupted cycles for high risk of OHSS was 13/290 (4.5%) in the rFSH plus rLH group and 2/289 (0.7%) in the HP-hMG group (OR 6.73, 95% CI 1.51-30.12, P = 0.013). One of the limitations of this study was the early closure and the ongoing PR could be overestimated. Both patient and gynaecologist were informed of the assigned treatment. Our results demonstrated the lack of differences in terms of ongoing PR between recombinant product and HP-hMG, in women ≥35 years undergoing controlled ovarian stimulation for IUI cycles. HP-hMG was safer than recombinant gonadotrophin concerning the risk of OHSS. None. NCT01604044. © The Author 2014.

The aim of the study was to develop and validate measures of awareness of symptoms and risk factors for ovarian and cervical cancer (Ovarian and Cervical Cancer Awareness Measures). Potentially relevant items were extracted from the literature and generated by experts. Four validation studies were carried out to establish reliability and validity. Women aged 21-67 years (n=146) and ovarian and cervical cancer experts (n=32) were included in the studies. Internal reliability was assessed psychometrically. Test-retest reliability was assessed over a 1-week interval. To establish construct validity, Cancer Awareness Measure (CAM) scores of cancer experts were compared with equally well-educated comparison groups. Sensitivity to change was tested by randomly assigning participants to read either a leaflet giving information about ovarian/cervical cancer or a leaflet with control information, and then completing the ovarian/cervical CAM. Internal reliability (Cronbach's α=0.88 for the ovarian CAM and α=0.84 for the cervical CAM) and test-retest reliability (r=0.84 and r=0.77 for the ovarian and cervical CAMs, respectively) were both high. Validity was demonstrated with cancer experts achieving higher scores than controls [ovarian CAM: t(36)= -5.6, p<0.001; cervical CAM: t(38)= -3.7, p=0.001], and volunteers who were randomised to read a cancer leaflet scored higher than those who received a control leaflet [ovarian CAM: t(49)=7.5, p<0.001; cervical CAM: t(48)= -5.5, p<0.001]. This study demonstrates the psychometric properties of the ovarian and cervical CAMs and supports their utility in assessing ovarian and cervical cancer awareness in the general population.

Iron accumulation in the endocrine glands has been implicated in the aetiopathogenesis of decreased reproductive capacity in patients with beta-thalassemia major (β-TM). The aim of the current study was to investigate the serum concentration of anti-Müllerian hormone (AMH), a marker of ovarian reserve, in women with transfusion-dependent β-TM. In this case-control study, we recruited 43 women with transfusion-dependent TM and 44 age-matched healthy controls. Hormonal and haematological parameters, serum level of AMH, antral follicle count, and ovarian volume were assessed. Twenty-two of the 43 women were hypogonadotropic, 8 with primary amenorrhea and 14 with secondary amenorrhea. FSH, LH, estradiol, prolactin, and AMH levels; antral follicle count; and ovarian volume were significantly lower in women with TM compared with the control group (p<0.05 for all). AMH level and other ovarian reserve markers are significantly diminished in women with transfusion-dependent TM compared to age-matched controls. Our findings support a deleterious effect of iron overload on ovarian tissue. Published by Elsevier B.V.

This study aimed to clarify the relationship between functional ovarian cysts and vitamin A, vitamin E, and folate intake. This case-control study evaluated 265 women of reproductive age who presented at gynaecology clinics of three hospitals in Mashhad, Iran. While women in the ovarian cyst group [n = 132] had functional ovarian cysts, control group [n = 133] consisted of women without functional ovarian cysts. The participants' vitamin A, vitamin E, and folate intake was assessed using the Food Frequency Questionnaire. Results showed that folate intake was significantly higher in the ovarian cyst group [p = .040]. No significant differences in vitamin A and vitamin E intake were observed between the two groups [p = .950 and .230, respectively]. It is concluded that women with functional ovarian cysts had significantly higher folate intake. Vitamin A and vitamin E intake had no significant effects on the incidence of these cysts.

To identify risk factors for anastomotic leakage (AL) in patients undergoing primary advanced ovarian cancer surgery and to evaluate the prognostic implication of AL on overall survival in these patients. We analyzed our institutional database for primary EOC and included all consecutive patients treated by debulking surgery including any type of full circumferential bowel resection beyond appendectomy between 1999 and 2015. We performed logistic regression models to identify risk factors for AL and log-rank tests and Cox proportional hazards models to evaluate the association between AL and survival. AL occurred in 36/800 (4.5%; 95% confidence interval [3%-6%]) of all patients with advanced ovarian cancer and 36/518 (6.9% [5%-9%]) patients undergoing bowel resection during debulking surgery. One hundred fifty-six (30.1%) patients had multiple bowel resections. In these patients, AL rate per patient was only slightly higher (9.0% [5%-13%]) than in patients with rectosigmoid resection only (6.9% [4%-10%]), despite the higher number of anastomosis. No independent predictive factors for AL were identified. AL was independently associated with shortened overall survival (HR 1.9 [1.2-3.4], p=0.01). In the present study, no predictive pre- and/or intraoperative risk factors for AL were identified. AL rate was mainly influenced by rectosigmoid resection and only marginally increased by additional bowel resections. Copyright © 2017 Elsevier Inc. All rights reserved.

To investigate the incidence and predictive factors of 30-day surgery-related morbidity and occult precancerous and cancerous conditions for women undergoing risk-reducing surgery. A prospective study (Canadian Task Force classification II-1). A gynecologic oncology referral center. Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). Minimally invasive risk-reduction surgery. Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery. Copyright © 2017 AAGL. Published by Elsevier Inc.

There is a broad range of possible diagnoses for an elevated beta human chorionic gonadotropin (β-hCG) in the absence of intrauterine or ectopic pregnancy. When women of child bearing potential undergo evaluation for clinical trial, it is often unclear what course of evaluation to take when a pregnancy test is positive. We describe the clinical course of a patient with widely metastatic mucinous ovarian carcinoma with metastasis to the peritoneum, lymph nodes and liver. The patient was found to have a mildly elevated β-hCG during initial evaluation for clinical trial. Extensive work up for ectopic pregnancy, trophoblastic disease, and phantom β-hCG were negative. The patient's β-hCG levels continued to rise until initiation of therapy. She was treated on a phase I protocol with restaging scans revealing a partial response. The β-hCG was retested and declined in conjunction with her response, consistent with paraneoplastic β-hCG. Here, we propose a decision making algorithm to evaluate a patient with an elevated β-hCG undergoing assessment for clinical trial.

Little is known about genetic service utilization and ovarian cancer. We identified the frequency and outcome of genetic counseling referral, predictors of referral, and referral uptake for ovarian cancer patients. Using pathology reports, we identified all epithelial ovarian cancer patients seen in a university gynecologic oncology clinic (1/04-8/06). Electronic medical records (EMR) were used to document genetic service referral, time from diagnosis-to-referral, point-in-treatment at referral, personal/family cancer history, demographics, and genetic test results. Groups were compared using chi-squared and Fisher's exact test for categorical variables and t-tests for continuous variables. The study population consisted of 376 women with ovarian cancer, 72 (19 %) of who were referred for genetic counseling/testing, primarily during surveillance. Of those referred, 42 (58 %) had personal or family genetic counseling and 34 (47 %) were ultimately tested or identified due to known family mutation. Family history and prior cancer were associated with referral. Family history, living in a larger community, higher-stage disease, and serous histology were associated with undergoing genetic counseling. Risk assessment identified 20 BRCA1/2 (5.3 %) and 1 HNPCC (0.3 %) mutation carriers. Based on recent estimates that 11.7-16.6 % of women with ovarian cancer are BRCA carriers and 2 % are HNPCC carriers, results suggest under-identification of carriers and under-utilization of genetic services by providers and patients. Interventions to increase medical providers' referrals, even in a specialized oncology clinic, are necessary and may include innovations in educating these providers using web-based methods. Ease of referral by the introduction of an electronic cancer genetic referral form represents another new direction that may increase genetic risk assessment for high-risk women with ovarian cancer.

The purpose of this study was to predict the poor and excessive ovarian response using anti-Müllerian hormone (AMH) levels following a long agonist protocol in IVF candidates. Through a prospective cohort study, the type of relationship and appropriate scale for AMH were determined using the fractional polynomial regression. To determine the effect of AMH on the outcomes of ovarian stimulation and different ovarian responses, the multi-nominal and negative binomial regression models were fitted using backward stepwise method. The ovarian response of study subject who entered a standard long-term treatment cycle with GnRH agonist was evaluated using prediction model, separately and in combined models with (ROC) curves. The use of standard long-term treatments with GnRH agonist led to positive pregnancy test results in 30% of treated patients. With each unit increase in the log of AMH, the odds ratio of having poor response compared to normal response decreases by 64% (OR 0.36, 95% CI 0.19-0.68). Also the results of negative binomial regression model indicated that for one unit increase in the log of AMH blood levels, the odds of releasing an oocyte increased 24% (OR 1.24, 95% CI 1.14-1.35). The optimal cut-off points of AMH for predicting excessive and poor ovarian responses were 3.4 and 1.2 ng/ml, respectively, with area under curves of 0.69 (0.60-0.77) and 0.76 (0.66-0.86), respectively. By considering the age of the patient undergoing infertility treatment as a variable affecting ovulation, use of AMH levels showed to be a good test to discriminate between different ovarian responses.

To develop a novel molecular panel of markers to detect breast cancer (BC) disseminated malignant cells in ovarian tissue, and to improve the safety of ovarian tissue transplantation. Experimental study. University hospital. Ten ovarian biopsies from healthy patients, 13 biopsies with diagnosed BC metastasis, and 4 biopsies from primary BC tumor for designing a diagnostic panel of BC cell contamination; 60 ovarian biopsies from BC patients undergoing fertility preservation for validating the panel. Female nude mice. A novel panel for BC malignant cell detection by reverse-transcription polymerase chain reaction (RT-PCR), inmmunohistochemical analysis, in vitro invasion assay and xenotransplantation assayed in ovarian tissue from BC patients. Expression of GCDFP15, MGB1, SBEM, MUC1, WT-1, and NY-BR-01, selected as markers, assessed by quantitative RT-PCR in samples with confirmed BC metastasis. The most sensitive markers were confirmed by immunohistochemistry, and tested in vitro and in vivo. GCDFP15, MGB1, and SBEM were the most sensitive and specific markers to detect BC metastatic cells when at least one was expressed by quantitative RT-PCR. The panel was validated in 60 patients and confirmed in an in vitro invasion assay, where no invasive cells were observed. Samples negative for BC cells cannot develop disease when xenografted. GCDFP15, MGB1, and SBEM were the most sensitive molecules to create a diagnostic panel for BC malignant cell contamination, which may make ovarian tissue cryopreservation and transplantation a safe technique for fertility preservation in BC patients.

To evaluate the effects of fulvestrant and micronized progesterone on post-operative adhesion formation and ovarian reserve in a rat uterine horn adhesion. In this prospective randomized controlled trial, 32 female Wistar albino rats were randomly divided into four groups including control group (Group 1), the control adhesion group (Group 2), 1 mg/kg daily intramuscular fulvestrant received group (Group 3) and 1 mg/kg daily oral micronized progesterone received group (Group 4). The extent and severity of adhesions were scored and samples were taken from adhesion areas to investigate the grades of adhesions according to the immunohistochemical scoring system. Ovarian reserves were measured with anti-Müllerian hormone (AMH) and histological ovarian follicles count. The extent, severity and total adhesion scores were reduced in all treatment groups compared to control adhesion group (Group 2). Similarly, immunohistochemical adhesion scores were lower in the treatment groups. AMH and follicle count were significantly found lower in adhesion groups compared with control group. However, treatment groups were found to have higher ovarian reserve compared to control adhesion group (Group 2). Fulvestrant and micronized progesterone were found to reduce post-operative adhesion formations and have decreased detrimental effects of adhesion formation on ovarian reserve.

To test the hypothesis that women with unexplained infertility demonstrate evidence of diminished ovarian reserve when compared with a population of community controls. Cross-sectional study. Multicenter university-based clinical practices. Study participants included 277 healthy, normo-ovulatory female partners with rigorously defined unexplained infertility randomly selected from a multicenter trial (Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation). Controls included 226 healthy, normo-ovulatory women not seeking treatment for fertility from a community-based cohort (Ovarian Aging study). Serum antimüllerian hormone (AMH) assay at a central laboratory, FSH, fasting serum metabolic testing, transvaginal ultrasonography for antral follicle counts (AFCs), anthropometric measurements. Average AMH, AFC, and AMH/AFC were compared between infertile and control women by age. Analyses of covariance compared these outcomes while controlling for confounders, including age, race, body mass index, smoking history, and study site. In our models, AMH, AFC, and AMH/AFC ovarian reserve indices did not differ between infertile women and community-based controls, after controlling for age, race, body mass index, smoking history, and study site. Currently utilized predictors of ovarian reserve do not discriminate women with rigorously defined unexplained infertility from healthy community-based women of similar demographic characteristics. Contrary to our hypothesis, among women with FSH in the normal range (≤12 IU/L), women with unexplained infertility did not show evidence of decreased ovarian reserve as measured by AMH and AFC. Ovarian reserve markers in isolation may not serve as predictors of future fertility. Copyright © 2017 American Society for Reproductive Medicine. All rights reserved.

Retinol (ROL) and its biologically active metabolite, all-trans retinoic acid (ATRA), are essential for a number of reproductive processes. However, there is a paucity of information regarding their roles in ovarian folliculogenesis, oocyte maturation, and early embryogenesis. The objectives of this study were to quantify and compare peripheral plasma (PP) and follicular fluid (FF) retinoid levels, including ATRA in women undergoing in vitro fertilization (IVF) and to investigate the relationship between retinoid levels and embryo quality. Retinoid levels were evaluated in PP and FF from 79 women undergoing IVF at the time of oocyte retrieval and corresponding embryo quality assessed on a daily basis after retrieval for 3 days until uterine transfer. Analysis compared the retinoid levels with day 3 embryo grades and between endometriosis versus control patients. Results demonstrated distinctive levels of retinoid metabolites and isomers in FF versus PP. There was a significantly larger percentage of high-quality grade I embryos derived from the largest versus smallest follicles. An increase in follicle size also correlated with a >50% increase in FF ROL and ATRA concentrations. Independent of follicle size, FF yielding grade I versus nongrade I embryos showed higher mean levels of ATRA but not ROL. In a nested case-control analysis, control participants had 50% higher mean levels of ATRA in their FF and PP than women with endometriosis. These findings strongly support the proposition that ATRA plays a fundamental role in oocyte development and quality, and that reduced ATRA synthesis may contribute to decreased fecundity of participants with endometriosis.

Salivary gland degeneration and ovarian development in the Rocky Mountain wood tick, Dermacentor andersoni Stiles (Acari: Ixodidae). I. Post-engorgement events.

It is well known that female ixodid ticks undergo salivary gland degeneration and the greater part of ovarian development following engorgement. The process has been particularly well studied in Amblyomma hebraeum, including the hormonal control of these processes. The purpose of this study, and the second one in this series, is to compare the processes in Dermacentor andersoni with those of A. hebraeum. A major difference between the two species is that virgin female D. andersoni feed to a much higher fed-to-unfed weight ratio than do virgin female A. hebraeum, the former achieving an average of 67× the unfed weight in this study, the latter normally achieving an average of only about 10-15× the unfed weight. We show here that although engorged virgins (defined here as those that exceed a fed-unfed weight ratio of 50, even though they do not detach from the host spontaneously) degenerate their salivary glands and develop their ovaries, these processes proceed more slowly in virgins that they do in mated females, as is the case for A. hebraeum.

To investigate the association between consumption of preserved foods and risk of epithelial ovarian cancer in southern Chinese women. A hospital-based case-control study was undertaken in Guangzhou, Guangdong Province, from 2006 to 2008. Participants were 500 incident epithelial ovarian cancer patients and 500 controls, with a mean age 59 years. Information on habitual food consumption was obtained by face-to-face interview using a validated and reliable food frequency questionnaire. Logistic regression analyses were performed to assess the association between preserved foods intake and the ovarian cancer risk. The ovarian cancer patients consumed more preserved foods (median 15.5, interquartile range (IQR) 18.2g/day) than controls (median 13.8, IQR 20.5 g/day), p<0.001. The adjusted odds ratios of ovarian cancer was 1.78 (95% confidence interval 1.35 to 2.34) for women consuming more than 13.5 g of preserved vegetables and preserved meats per day relative to those below. Similar two-fold increases in risk at high level of intake were also evident for serous and mucinous subtypes of epithelial ovarian tumours. Intake of preserved foods was positively associated with the incidence of epithelial ovarian cancer in southern Chinese women. Copyright © 2013 Elsevier Inc. All rights reserved.

Modest increases of serum progesterone at human chorionic gonadotrophin (hCG) administration in controlled ovarian hyperstimulation (COH) cycles have been shown to have a negative impact on pregnancy outcomes. The aim of this study was to identify early predictors of progesterone elevation at hCG. Pregnancy outcome of 303 consecutive patients undergoing COH and fresh day-3 embryo transfer was analysed. Considering the non-linear relationship between progesterone at hCG triggering and pregnancy outcomes, partial area under the curve (pAUC) analysis was used to implement marker identification potential of receiver operating characteristic (ROC) curve analysis. Multivariate logistic analysis was then performed to identify predictors of progesterone rise. Pregnancy outcomes could be predicted by pAUC analysis (pAUC = 0.58, 95 % CI 0.51-0.66, p = 0.02) and a significant detrimental cut-off could be calculated (progesterone at hCG > 1.35 ng/ml). Total dose of rFSH administered, E2 level at hCG but mostly basal progesterone level (OR = 12.21, 95 % CI 1.82-81.70) were predictors of progesterone rise above the cut-off. Basal progesterone is shown to be the main prognostic factor for progesterone elevation. This observation should be taken into consideration in the clinical management of IVF/ICSI cycles to improve pregnancy outcomes.

The reports on how to stimulate the ovaries for oocyte retrieval in good prognosis patients are contradictory and often favor one type of controlled ovarian hyperstimulation (COH). For this reason, we retrospectively analyzed data from IVF/ICSI cycles carried out at our IVF Unit in good prognosis patients (aged <38 years, first and second attempts of IVF/ICSI, more than 3 oocytes retrieved) to elucidate which type of COH is optimal at our condition. The included patients were undergoing COH using GnRH agonist, GnRH antagonist or GnRH antagonist mild protocol in combination with gonadotrophins. We found significant differences in the average number of retrieved oocytes, immature oocytes, fertilized oocytes, embryos, transferred embryos, embryos frozen per cycle, and cycles with embryo freezing between studied COH protocols. Although there were no differences in live birth rate (LBR), miscarriages, and ectopic pregnancies between compared protocols, pregnancy rate was significantly higher in GnRH antagonist mild protocol in comparison with both GnRH antagonist and GnRH agonist protocols and cumulative LBR per cycle was significantly higher in GnRH antagonist mild protocol in comparison to GnRH agonist protocol. Our data show that GnRH antagonist mild protocol of COH could be the best method of choice in good prognosis patients.

Cancer treatments have significant negative impacts on female fertility, but the impact of cancer itself on fertility remains to be clarified. While some studies have shown that compared with healthy women, those with cancer require higher doses of gonadotropins resulting in decreased oocyte yields, others have shown comparable oocyte yields between the two groups. The purpose of this study is to evaluate whether there is an association between any cancer and/or type of cancer, and response to ovarian stimulation for egg and embryo banking. In this retrospective cohort study, ovarian stimulation cycles performed from June 2007 through October 2014 at a single academic medical center were reviewed to identify those undertaken for women with cancer undergoing fertility preservation ( n  = 147) or women with no cancer undergoing their first cycle due to male factor infertility ( n  = 664). Of the 147 women undergoing fertility preservation, 105 had local cancer (Stage I-III solid malignancies) and 42 had systemic cancer (hematologic or Stage IV solid malignancies). Response to ovarian stimulation was compared among these two groups and women with no cancer. Adjusting for age and BMI, women with systemic cancer had lower baseline antral follicle counts (AFC) than women with no cancer or local cancer. Women with systemic cancer required higher doses of FSH than women with no cancer or local cancer, and they had higher oocyte to AFC ratios than women with no cancer or local cancer, but greater odds of cycle cancellation as compared to women with no cancer or local cancer. No significant differences were observed among the three groups for duration of stimulation, number of oocytes and mature oocytes retrieved, or number of embryos created. Women with cancer achieve similar oocyte and embryo yields as women with no cancer, although those with systemic cancer require higher FSH doses and are at greater risk of cycle cancellation.

To assess whether antimüllerian hormone (AMH) is a predictor of implantation and/or clinical pregnancy in women undergoing assisted reproductive technology. Systematic review and meta-analysis. Not applicable. Women undergoing IVF/intracytoplasmic sperm injection in nondonor cycles. Measurement of serum AMH level. Diagnostic odds ratio (OR) and summary receiver operating characteristic curve (AUC) for AMH as a predictor of implantation and/or clinical pregnancy. A total of 525 observational studies were identified, of which 19 were selected (comprising 5,373 women). Studies reporting clinical pregnancy rates in women with unspecified ovarian reserve (n = 11), diminished ovarian reserve (DOR) (n = 4), and polycystic ovary syndrome (n = 4) were included, together with studies reporting implantation rates (n = 4). The OR for AMH as a predictor of implantation in women with unspecified ovarian reserve (n = 1,591) was 1.83 (95% confidence interval [CI] 1.49-2.25), whereas the AUC was 0.591 (95% CI 0.563-0.618). The OR for AMH as a predictor of clinical pregnancy in these women (n = 4,324) was 2.10 (95% CI 1.82-2.41), whereas the AUC was 0.634 (95% CI 0.618-0.650). The predictive ability of AMH for pregnancy was greatest in women with DOR (n = 615), with OR and AUC of 3.96 (95% CI 2.57-6.10) and 0.696 (95% CI 0.641-0.751), respectively. In contrast, AMH had no significant predictive ability in women with PCOS (n = 414), with OR and AUC of 1.18 (95% CI 0.53-2.62) and 0.600 (95% CI 0.547-0.653), respectively. Antimüllerian hormone has weak association with implantation and clinical pregnancy rates in assisted reproductive technology but may still have some clinical utility in counseling women undergoing fertility treatment regarding pregnancy rates, particularly those with DOR.

To evaluate whether methotrexate (MTX) compromises ovarian reserve and future reproductive outcome in women undergoing assisted reproductive technology (ART), when it is used as first-line treatment for ectopic pregnancy (EP). Prospective, observational study. University-affiliated private IVF unit. Twenty-five women undergoing IVF-ICSI who were treated with MTX (1 mg/kg IM) for an EP after ART. Evaluation of reproductive outcome and serum anti-Müllerian hormone (AMH) levels. Serum AMH was evaluated before administering MTX and >or=1 week after the resolution of the EP. Reproductive outcome was evaluated by comparing subsequent IVF-ICSI cycles after EP resolution. Serum AMH levels, cycle length, gonadotropin dose required, peak serum E(2) level, oocytes collected, and embryos obtained. Serum AMH levels before MTX were not statistically significantly different from those after treatment (3.7 +/- 0.3 ng/mL vs. 3.9 +/- 0.3 ng/mL). Patients undergoing a subsequent cycle after systemic treatment for EP had similar cycle durations (10.3 vs. 10.8 d), gonadotropin requirements (2,775 vs. 2,630.3 IU), peak E(2) levels (1,884.3 vs. 1,523.6 pg/mL), number of oocytes retrieved (12.1 vs. 10.5), and total number of embryos obtained (7.1 vs. 6.5). Single-dose MTX is a safe first-treatment choice that does not compromise future reproductive outcomes in women who are diagnosed with EP after ART.

Monitoring of stimulated cycles in assisted reproduction (IVF and ICSI).

Traditional monitoring of ovarian hyperstimulation during in vitro fertilisation (IVF) and intra-cytoplasmic sperm injection (ICSI) treatment has included transvaginal ultrasonography (TVUS) plus serum estradiol levels to ensure safe practice by reducing the incidence and severity of ovarian hyperstimulation syndrome (OHSS) whilst achieving the good ovarian response needed for assisted reproduction treatment. The need for combined monitoring (using TVUS and serum estradiol) during ovarian stimulation in assisted reproduction is controversial. It has been suggested that combined monitoring is time consuming, expensive and inconvenient for women and that simplification of IVF and ICSI therapy by using TVUS only should be considered. To assess the effect of monitoring controlled ovarian hyperstimulation (COH) in IVF and ICSI cycles in subfertile couples with TVUS only versus TVUS plus serum estradiol concentration, with respect to rates of live birth, pregnancy and OHSS. We searched the Menstrual Disorders and Subfertility Group Specialised Register of controlled trials, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, PsycINFO, the National Research Register, and web-based trial registers such as Current Controlled Trials. The last search was conducted in May 2014. There was no language restriction applied. All references in the identified trials and background papers were checked and authors were contacted to identify relevant published and unpublished data. Only randomised controlled trials that compared monitoring with TVUS only versus TVUS plus serum estradiol concentrations in women undergoing COH for IVF and ICSI treatment were included. Three review authors independently selected the studies, extracted data and assessed risk of bias. They resolved disagreements by discussion with the rest of the authors. Outcomes data were pooled and summary statistics were presented when appropriate. The quality of the evidence was rated using the GRADE methods. With this update, four new studies were identified resulting in a total of six trials including 781 women undergoing monitoring of COH with either TVUS alone or a combination of TVUS and serum estradiol concentration during IVF or ICSI treatment.None of the six studies reported our primary outcome of live birth rate. Pooled data showed no evidence of a difference in clinical pregnancy rate per woman between monitoring with TVUS only and combined monitoring (odds ratio (OR) 1.10; 95% confidence interval (CI) 0.79 to 1.54; four studies; N = 617; I² = 5%; low quality evidence). This suggests that compared with women with a 34% chance of clinical pregnancy using monitoring with TVUS plus serum estradiol, the clinical pregnancy rate in women using TVUS only was between 29% and 44%.There was no evidence of a difference between the groups in the reported cases of OHSS (OR 1.03; 95% CI 0.48 to 2.20; six studies; N = 781; I² = 0%; low quality evidence), suggesting that compared with women with a 4% chance of OHSS using monitoring with TVUS plus serum estradiol, the OHSS rate in women monitored by TVUSS only was between 2% and 8%.There was no evidence of a difference between the groups in the mean number of oocytes retrieved pre woman (mean difference (MD) 0.32; 95% CI -0.60 to 1.24; five studies; N = 596; I² = 17%; low quality evidence).The evidence was low quality for all comparisons. Limitations included imprecision and potential bias due to unclear randomisation methods, allocation concealment and blinding, as well as differences in treatment protocols. Quality assessment was hampered by the lack of methodological descriptions in several studies. This review update found no evidence from randomised trials to suggest that combined monitoring by TVUS and serum estradiol is more efficacious than monitoring by TVUS alone with regard to clinical pregnancy rates and the incidence of OHSS. The number of oocytes retrieved appeared similar for both monitoring protocols. The data suggest that both these monitoring methods are safe and reliable. However, these results should be interpreted with caution because the overall quality of the evidence was low. Results were compromised by imprecision and poor reporting of study methodology. A combined monitoring protocol including both TVUS and serum estradiol may need to be retained as precautionary good clinical practice and as a confirmatory test in a subset of women to identify those at high risk of OHSS. An economic evaluation of the costs involved with the two methods and the views of the women undergoing cycle monitoring would be welcome.

Ovarian cancer (OC) is associated with non-specific symptoms such as bloating, making accurate diagnosis challenging: only 1 in 3 women with OC presents through primary care referral. National Institute for Health and Care Excellence guidelines recommends sequential testing with CA125 and routine ultrasound in primary care. However, these diagnostic tests have limited sensitivity or specificity. Improving accurate triage in women with vague symptoms is likely to improve mortality by streamlining referral and care pathways. The Refining Ovarian Cancer Test Accuracy Scores (ROCkeTS; HTA 13/13/01) project will derive and validate new tests/risk prediction models that estimate the probability of having OC in women with symptoms. This protocol refers to the prospective study only (phase III). ROCkeTS comprises four parallel phases. The full ROCkeTS protocol can be found at http://www.birmingham.ac.uk/ROCKETS. Phase III is a prospective test accuracy study. The study will recruit 2450 patients from 15 UK sites. Recruited patients complete symptom and anxiety questionnaires, donate a serum sample and undergo ultrasound scored as per International Ovarian Tumour Analysis (IOTA) criteria. Recruitment is at rapid access clinics, emergency departments and elective clinics. Models to be evaluated include those based on ultrasound derived by the IOTA group and novel models derived from analysis of existing data sets. Estimates of sensitivity, specificity, c-statistic (area under receiver operating curve), positive predictive value and negative predictive value of diagnostic tests are evaluated and a calibration plot for models will be presented. ROCkeTS has received ethical approval from the NHS West Midlands REC (14/WM/1241) and is registered on the controlled trials website (ISRCTN17160843) and the National Institute of Health Research Cancer and Reproductive Health portfolios.

Purpose The majority of previous studies have observed an increased risk of mucinous ovarian tumors associated with cigarette smoking, but the association with other histological types is unclear. In a large pooled analysis, we examined the risk of epithelial ovarian cancer associated with multiple measures of cigarette smoking with a focus on characterizing risks according to tumor behavior and histology. Methods We used data from 21 case–control studies of ovarian cancer (19,066 controls, 11,972 invasive and 2,752 borderline cases). Study-specific odds ratios (OR) and 95 % confidence intervals (CI) were obtained from logistic regression models and combined into a pooled odds ratio using a random effects model. Results Current cigarette smoking increased the risk of invasive mucinous (OR = 1.31; 95 % CI: 1.03–1.65) and borderline mucinous ovarian tumors (OR = 1.83; 95 % CI: 1.39–2.41), while former smoking increased the risk of borderline serous ovarian tumors (OR = 1.30; 95 % CI: 1.12–1.50). For these histological types, consistent dose– response associations were observed. No convincing associations between smoking and risk of invasive serous and endometrioid ovarian cancer were observed, while our results provided some evidence of a decreased risk of invasive clear cell ovarian cancer. Conclusions Our results revealed marked differences in the risk profiles of histological types of ovarian cancer with regard to cigarette smoking, although the magnitude of the observed associations was modest. Our findings, which may reflect different etiologies of the histological types, add to the fact that ovarian cancer is a heterogeneous disease. PMID:23456270

Sirolimus has been approved for clinical use in non proliferative and proliferative disorders. It inhibits the mammalian target of rapamycin (mTOR) signaling pathway which is also known to regulate ovarian morphology and function. Preliminary observational data suggest the potential for ovarian toxicity but this issue has not been studied in randomized controlled trials. We reviewed the self-reported occurrence of menstrual cycle disturbances and the appearance of ovarian cysts post hoc in an open label randomized controlled phase II trial conducted at the University Hospital Zürich between March 2006 and March 2010. Adult females with autosomal dominant polycystic kidney disease, an inherited kidney disease not known to affect ovarian morphology and function, were treated with 1.3 to 1.5 mg sirolimus per day for a median of 19 months (N = 21) or standard care (N = 18). Sirolimus increased the risk of both oligoamenorrhea (hazard ratio [HR] 4.3, 95% confidence interval [CI] 1.1 to 29) and ovarian cysts (HR 4.4, CI 1.1 to 26); one patient was cystectomized five months after starting treatment with sirolimus. We also studied mechanisms of sirolimus-associated ovarian toxicity in rats. Sirolimus amplified signaling in rat ovarian follicles through the pro-proliferative phosphatidylinositol 3-kinase pathway. Low dose oral sirolimus increases the risk of menstrual cycle disturbances and ovarian cysts and monitoring of sirolimus-associated ovarian toxicity is warranted and might guide clinical practice with mammalian target of rapamycin inhibitors.

Inflammation has been implicated in ovarian carcinogenesis. However, studies investigating the association between pelvic inflammatory disease (PID) and ovarian cancer risk are few and inconsistent. We investigated the association between PID and the risk of epithelial ovarian cancer according to tumor behavior and histotype. We pooled data from 13 case-control studies, conducted between 1989 and 2009, from the Ovarian Cancer Association Consortium (OCAC), including 9,162 women with ovarian cancers, 2,354 women with borderline tumors, and 14,736 control participants. Study-specific odds ratios were estimated and subsequently combined into a pooled odds ratio using a random-effects model. A history of PID was associated with an increased risk of borderline tumors (pooled odds ratio (pOR) = 1.32, 95% confidence interval (CI): 1.10, 1.58). Women with at least 2 episodes of PID had a 2-fold increased risk of borderline tumors (pOR = 2.14, 95% CI: 1.08, 4.24). No association was observed between PID and ovarian cancer risk overall (pOR = 0.99, 95% CI: 0.83, 1.19); however, a statistically nonsignificantly increased risk of low-grade serous tumors (pOR = 1.48, 95% CI: 0.92, 2.38) was noted. In conclusion, PID was associated with an increased risk of borderline ovarian tumors, particularly among women who had had multiple episodes of PID. Although our results indicated a histotype-specific association with PID, the association of PID with ovarian cancer risk is still somewhat uncertain and requires further investigation.

The effects of moclobemide on damaged ovarian tissue induced by ischemia- reperfusion and damaged contralateral ovarian tissue were investigated in rats, biochemically and histologically. In this experimental study, 40 rats were equally divided into four groups: 10 mg/kg moclobemide, 20 mg/kg moclobemide, ischemia/reperfusion control, and intact control groups. A 2-2.5-cm-long vertical incision was made in the lower abdomen of each rat in order to reach the ovaries, after which a vascular clip was placed on the lower side of the right ovary of each animal in the two treatment groups and the ischemia-reperfusion control group, but not in the healthy (intact control) animal group. The purpose of this procedure was to create ischemia over the course of three hours, then the clips were unclamped to provide reperfusion for the next two hours. At the end of the two hours of reperfusion, all the animals were killed by high-dose anaesthesia and their ovaries were taken and subjected to histological and biochemical (malondialdehyde, nitric oxide, glutathione) studies. The obtained results showed that moclobemide suppressed nitric oxide and malondialdehyde production in the ischemia-reperfusion damage area, and prevented the decrease in endogenous antioxidant levels (glutathione) in the rat ovarian tissue. Moclobemide also prevented infiltration of leukocytes to the ovarian tissue. These results showed that moclobemide protected ovarian tissue against ischemiareperfusion injury. This study shows that moclobemide represses malondialdehyde and nitric oxide production in the rat ovarian tissue subjected to ischemia-reperfusion injury and keeps the endogenous antioxidant glutathione level from decreasing. Moclobemide also inhibits leukocytic migration into ovarian tissue following ischemia-reperfusion injury. From these results, it is suggested that moclobemide can be used in the treatment of ovarian ischemia-reperfusion injury.

The standard treatment for ovarian cancer is chemotherapy with 2 drugs (taxanes and platinum drugs). However, the traditional combination of the 2 drugs has many adverse effects (AEs) and the cancer cells will quickly become resistant to the drugs. Apatinib is a small-molecule antiangiogenic agent which has shown promising therapeutic effects against diverse tumor types, but it still remains unknown whether apatinib has an antitumor effect in patients with ovarian cancer. Herein, we present a successfully treated case of ovarian cancer using chemotherapy and apatinib, in order to demonstrate the effectiveness of this new combined regimen in ovarian cancer. A 51-year-old Chinese woman presented with ovarian cancer >4.5 years. The disease and the cancer antigen 125 (CA-125) had been controlled well by surgical treatment and following chemotherapy. However, the drugs could not control the disease anymore as the CA-125 level was significantly increasing. Ovarian cancer. The patient was treated with apatinib combined with epirubicin. Apatinib was administered orally, at an initial daily dose of 500 mg, and was then reduced to 250 mg qd after the appearance of intolerable hand-foot syndrome (HFS) and oral ulcer. Then, the oral ulcer disappeared and the HFS was controlled by dose adjustment, oral vitamin B6, and hand cream application. The CA-125 reverted to the normal value after treatment with the new regimen. Magnetic resonance imaging showed that the original tumor lesions had disappeared. Apatinib monotherapy as maintenance therapy was then used to successfully control the cancer with a complete response. Our study is the first, to our knowledge, to report the therapeutic effects of apatinib and epirubicin on ovarian cancer. Apatinib combined with chemotherapy and apatinib monotherapy as maintenance therapy could be a new therapeutic strategy for ovarian cancer, especially adenocarcinomas.

To evaluate the long-term cost-effectiveness of germline BRCA1 and BRCA2 (collectively termed "BRCA") testing in women with epithelial ovarian cancer, and testing for the relevant mutation in first- and second-degree relatives of BRCA mutation-positive individuals, compared with no testing. Female BRCA mutation-positive relatives of patients with ovarian cancer could undergo risk-reducing mastectomy and/or bilateral salpingo-oophorectomy. A cost-effectiveness model was developed that included the risks of breast and ovarian cancer; the costs, utilities, and effects of risk-reducing surgery on cancer rates; and the costs, utilities, and mortality rates associated with cancer. BRCA testing of all women with epithelial ovarian cancer each year is cost-effective at a UK willingness-to-pay threshold of £20,000/quality-adjusted life-year (QALY) compared with no testing, with an incremental cost-effectiveness ratio of £4,339/QALY. The result was primarily driven by fewer cases of breast cancer (142) and ovarian cancer (141) and associated reductions in mortality (77 fewer deaths) in relatives over the subsequent 50 years. Sensitivity analyses showed that the results were robust to variations in the input parameters. Probabilistic sensitivity analysis showed that the probability of germline BRCA mutation testing being cost-effective at a threshold of £20,000/QALY was 99.9%. Implementing germline BRCA testing in all patients with ovarian cancer would be cost-effective in the United Kingdom. The consequent reduction in future cases of breast and ovarian cancer in relatives of mutation-positive individuals would ease the burden of cancer treatments in subsequent years and result in significantly better outcomes and reduced mortality rates for these individuals.

Chemotherapy for breast cancer may have a negative impact on reproductive function due to gonadotoxicity. Fertility preservation via banking of oocytes or embryos after ovarian stimulation with FSH can increase the likelihood of a future live birth. It has been hypothesized that elevated serum estrogen levels during ovarian stimulation may induce breast tumour growth. This has led to the use of alternative stimulation protocols with addition of tamoxifen or letrozole. The effectiveness of these stimulation protocols in terms of oocyte yield is unknown. Randomized open-label trial comparing ovarian stimulation plus tamoxifen and ovarian stimulation plus letrozole with standard ovarian stimulation in the course of fertility preservation. The study population consists of women with breast cancer who opt for banking of oocytes or embryos, aged 18-43years at randomisation. Primary outcome is the number of oocytes retrieved at follicle aspiration. Secondary outcomes are number of mature oocytes retrieved, number of oocytes or embryos banked and peak E2 levels during ovarian stimulation. Concerning the lack of evidence on which stimulation protocol should be used in women with breast cancer and the growing demand for fertility preservation, there is an urgent need to undertake this study. By performing this study, we will be able to closely monitor the effects of various stimulation protocols in women with breast cancer and pave the way for long term follow up on the safety of this procedure in terms of breast cancer prognosis.

A major cause of cycle cancellation during controlled ovarian hyperstimulation (COH) in women undergoing in vitro fertilization (IVF) is the occurrence of premature luteinizing hormone (LH) surges. Steroidal preparations can modulate the secretion of gonadotropins (Gn); however, few studies using progesterone to inhibit the premature LH surges in COH have been published. The purpose of the study was to evaluate the oral delivery of progesterone soft capsules (Utrogestan) to prevent LH surges from the follicular phase and to compare cycle characteristics as well as to evaluate pregnancy outcomes in subsequent frozen-thawed embryo transfer (FET) cycles. A total of 374 patients were enrolled in this retrospective study, among which 187 patients were simultaneously administered Utrogestan and human menopausal gonadotrophin (hMG) from cycle day 3 until the trigger day. A short protocol including 187 controls with comparable age, body mass index (BMI), infertility duration, and antral follicle count was also used. GnRH agonist (0.1 mg) or hCG (3000 IU) was used for a trigger when the dominant follicles matured. Viable embryos were cryopreserved for later transfer in both groups. The primary outcome was the number of oocytes retrieved. The secondary outcomes included the number of mature oocytes, incidence of premature LH surge, and clinical pregnancy outcomes from FET cycles. Consistent LH suppression was achieved during COH, with a range of 0.07 to 8.9 IU/L, and no premature LH surge was detected. The number of oocytes retrieved in the Utrogestan and hMG protocol was comparable with that in the short protocol (10.92 ± 5.74 vs 10.6 ± 6.22, P > 0.05), and the dose of hMG was higher than that used in the short protocol (1884.22 ± 439.47 IU vs 1446.26 ± 550.48 IU, P < 0.05). No significant between-group difference was observed in the mature oocyte rate (88.88% vs 90.12%), cleavage rate (96.58% vs 96.58%), clinical pregnancy rate (54.27% vs 51.65%), or implantation rate (33.59% vs 34.02%). The study shows that Utrogestan is an effective oral alternative for preventing premature LH surges in women undergoing COH, which will help to establish a convenient user regimen in combination with FET.

The objective of this study was to evaluate ovarian follicular dynamics during intervals between successive ovum pick-up (OPU) and determine its effects on the number and quality of recovered cumulus-oocyte complexes (COCs) in Zebu cows (Bos indicus). Pluriparous nonlactating Gyr cows (Bos indicus; n=10) underwent four consecutive OPU sessions at 96-h intervals. The dynamics of ovarian follicular growth between OPU sessions was monitored by twice-daily ultrasonographic examinations. A single dominant follicle (DF) or two codominant (CDF) follicles (>9mm) were present in 63.3% (19 of 30) of intervals studied, with follicle deviation beginning when the future dominant follicle (F1) achieved a diameter of 6.2+/-0.3mm. The phenomenon of codominance was observed in four (13.3%) of the inter-OPU intervals. The remaining intervals (36.6%, 11 of 30) were characterized by a greater follicular population, lower rate of follicular growth, and a smaller diameter F1 (P<0.0001). There was a tendency (P=0.08) toward an increase in the number of recovered COCs when dominant follicles were not present (NDF). The quality of COCs was not affected by the presence of a single dominant follicle, but codominant follicles resulted in recovery of a lower proportion of viable embryos (40.0%, 62.1%, and 63.6%; P<0.05) and higher proportions of degenerate COCs (56.0%, 30.3%, and 28.6%; P<0.05) for CDF, NDF, and DF respectively. We concluded that, in Zebu cows, (a) repeated follicle aspirations altered ovarian follicular dynamics, perhaps by increasing follicular growth rate; (b) follicular dominance could be established in cows undergoing twice-a-week OPU; and (c) the presence of a dominant follicle during short inter-OPU intervals may not affect COC quality, except when a codominant follicle was present.

Aberrant changes of N-glycan modifications on proteins have been linked to various diseases including different cancers, suggesting possible avenue for exploring their etiologies based on N-glycomic analysis. Changes in N-glycan patterns during epithelial ovarian cancer development have so far been investigated mainly using serum, plasma, ascites, and cell lines. However, changes in patterns of N-glycans in tumor tissues during epithelial ovarian cancer progression have remained largely undefined. To investigate whether changes in N-glycan patterns correlate with oncogenesis and progression of epithelial ovarian cancer, we profiled N-glycans from formalin-fixed paraffin-embedded tissue slides using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and quantitatively compared among different pathological grades of epithelial ovarian cancer and healthy controls. Our results show that among the 80 compositions of N-glycan detected, expression levels of high-mannose type were higher in epithelial ovarian cancer samples than that observed in healthy controls, accompanied by reduced levels of hybrid-type glycans. By applying receiver operating characteristic analysis, we show that a combined panel composed of four high-mannose and three fucosylated neutral complex N-glycans allows for good discrimination of epithelial ovarian cancer from healthy controls. Furthermore, using a statistical analysis of variance assay, we found that different N-glycan patterns, including 2 high-mannose-type, 2 fucosylated and sialylated complex structures, and 10 fucosylated neutral complex N-glycans, exhibited specific changes in N-glycan abundance across epithelial ovarian cancer grades. Together, our results provide strong evidence that N-glycomic changes are a strong indicator for epithelial ovarian cancer pathological grades and should provide avenues to identify novel biomarkers for epithelial ovarian cancer diagnosis and monitoring.

Inflammation has been implicated in ovarian carcinogenesis. However, studies investigating the association between pelvic inflammatory disease (PID) and ovarian cancer risk are few and inconsistent. We investigated the association between PID and the risk of epithelial ovarian cancer according to tumor behavior and histotype. We pooled data from 13 case-control studies, conducted between 1989 and 2009, from the Ovarian Cancer Association Consortium (OCAC), including 9,162 women with ovarian cancers, 2,354 women with borderline tumors, and 14,736 control participants. Study-specific odds ratios were estimated and subsequently combined into a pooled odds ratio using a random-effects model. A history of PID was associated with an increased risk of borderline tumors (pooled odds ratio (pOR) = 1.32, 95% confidence interval (CI): 1.10, 1.58). Women with at least 2 episodes of PID had a 2-fold increased risk of borderline tumors (pOR = 2.14, 95% CI: 1.08, 4.24). No association was observed between PID and ovarian cancer risk overall (pOR = 0.99, 95% CI: 0.83, 1.19); however, a statistically nonsignificantly increased risk of low-grade serous tumors (pOR = 1.48, 95% CI: 0.92, 2.38) was noted. In conclusion, PID was associated with an increased risk of borderline ovarian tumors, particularly among women who had had multiple episodes of PID. Although our results indicated a histotype-specific association with PID, the association of PID with ovarian cancer risk is still somewhat uncertain and requires further investigation. © The Author 2016.

Ovarian cancer is the most lethal gynecologic disease in the United States, with more women dying from this cancer than all gynecological cancers combined. Ovarian cancer has been termed the "silent killer" because some patients do not show clear symptoms at an early stage. Currently, there is a lack of approved and effective early diagnostic tools for ovarian cancer. There is also an apparent severe knowledge gap of ovarian cancer in general and of its indicative symptoms among both public and many health professionals. These factors have significantly contributed to the late stage diagnosis of most ovarian cancer patients (63% are diagnosed at Stage III or above), where the 5-year survival rate is less than 30%. The paucity of knowledge concerning ovarian cancer in the United States is unknown. The present investigation examined current public awareness and knowledge about ovarian cancer. The study implemented design strategies to develop an unbiased survey with quality control measures, including the modern application of multiple statistical analyses. The survey assessed a reasonable proxy of the US population by crowdsourcing participants through the online task marketplace Amazon Mechanical Turk, at a highly condensed rate of cost and time compared to traditional recruitment methods. Knowledge of ovarian cancer was compared to that of breast cancer using repeated measures, bias control and other quality control measures in the survey design. Analyses included multinomial logistic regression and categorical data analysis procedures such as correspondence analysis, among other statistics. We confirmed the relatively poor public knowledge of ovarian cancer among the US population. The simple, yet novel design should set an example for designing surveys to obtain quality data via Amazon Mechanical Turk with the associated analyses.

The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study. The study group consisted of rats exposed to an EMF in the abdominal region for 15 min/d for 15 days. Both the study and control group were composed of eight rats. After the treatment period of 15 days, the ovaries of the rats were extracted, and sections of ovarian tissue were taken for histological evaluation. The independent samples t test was used to compare the two groups. In the study group, the means of the right and left ovarian follicle numbers were 34.00 ± 10.20 and 36.00 ± 10.53, respectively. The average total ovarian follicle number was 70.00 ± 19.03. In the control group, the means of the right and left ovarian follicle numbers were 78.50 ± 25.98 and 71.75 ± 29.66, respectively, and the average total ovarian follicle number was 150.25 ± 49.53. The comparisons of the means of the right and left ovarian follicle numbers and the means of the total ovarian follicle numbers between the study and control groups indicated that the study group had significantly fewer follicles (p < 0.001, p = 0.011, and p = 0.002, respectively). This study found a significant decrease in the number of ovarian follicles in rats exposed to an EMF. Further clinical studies are needed to reveal the effects of EMFs on ovarian reserve and infertility. Copyright © 2015. Published by Elsevier Taiwan.

Previous studies examining associations between use of fertility drugs and ovarian cancer risk have provided conflicting results. We used data from a large case-control study to determine whether fertility drug use significantly impacts ovarian cancer risk when taking into account parity, gravidity, and cause of infertility. Data from the Hormones and Ovarian Cancer Prediction (HOPE) study were used (902 cases, 1,802 controls). Medical and reproductive histories were collected via in-person interviews. Logistic regression was used to calculate ORs and 95% confidence intervals (CI). Models were adjusted for age, race, education, age at menarche, parity, oral contraceptive use, breastfeeding, talc use, tubal ligation, and family history of breast/ovarian cancer. Ever use of fertility drugs was not significantly associated with ovarian cancer within the total HOPE population (OR, 0.93; 95% CI, 0.65-1.35) or among women who reported seeking medical attention for infertility (OR, 0.87; 95% CI, 0.54-1.40). We did observe a statistically significant increased risk of ovarian cancer for ever use of fertility drugs among women who, despite seeking medical attention for problems getting pregnant, remained nulligravid (OR, 3.13; 95% CI, 1.01-9.67). These results provide further evidence that fertility drug use does not significantly contribute to ovarian cancer risk among the majority of women; however, women who despite infertility evaluation and fertility drug use remain nulligravid, may have an elevated risk for ovarian cancer. Our results suggest that fertility drug use does not significantly contribute to overall risk of ovarian cancer when adjusting for known confounding factors. ©2012 AACR.

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in gynecology. In PCOS patients vascularization parameters are altered. Transvaginal hydrolaparoscopy (THL) is a mini-invasive approach for ovarian drilling in PCOS patients. In this study, we assessed the effect of ovarian drilling using THL on ovarian volume (OV) and vascularization index (VI) using 3D power Doppler ultrasonography in CC-resistant PCOS patients. A case-control study on 123 CC-resistant PCOS women who underwent THL ovarian drilling was performed. Patients underwent 3D ultrasound and power Doppler to measure VI, flow index (FI), vascularization flow index (VFI) and to evaluate OV before and after the procedure, at six months, and on the early follicular phase of the menstrual cycle. After THL ovarian drilling, OV and power Doppler flow indices were significantly reduced compared to pre-operative values (OV: 7.85 versus 11.72 cm 3 , p < 0.01; VI: 2.50 versus 4.81, p < 0.01; VFI: 1.10 versus 2.16, p < 0.01; FI: 32.05 versus 35.37, p < 0.01). In conclusion, THL ovarian drilling seems to reduce OV and 3D power Doppler indices, and could therefore be a viable alternative to LOD in PCOS patients resistant to medical therapy.

Endometriosis is a chronic inflammatory disease which results in significant pain and long term reproductive consequences for up to 50% of infertile women. This study was focused to understand how endometriosis altered the uterine and cervical bacterial community. Urogenital swabs and uterine washes were collected from 19 pre-menopausal women undergoing laparoscopic surgery for pelvic pain, suspected endometriosis (experimental n = 10), and women undergoing laparoscopic surgery for benign ovarian/uterine conditions (control n = 9). Patients were followed for the next year and repeat cervical swabs were obtained. Bacterial community composition was assessed from these samples using Illumina next generation 16Smore » rRNA amplicon sequencing. Bacterial communities were significantly different between sample sites, the uterus and cervix, and stage III endometriosis resulted in significant alterations in the cervical bacterial community. Both bacterial richness and phylogenetic diversity increased in association with stage III endometriosis. Surgical intervention resulted in a stabilized cervical bacterial community for a short period of time. Lastly, bacterial community profiling may provide a useful diagnostic tool for identifying endometriosis in asymptomatic, infertile women in a clinical setting.« less

The aim of this study was to determine the performance of prostate specific antigen (PSA) and ultrasound parameters, such as ovarian volume and outline, in the diagnosis of polycystic ovary syndrome (PCOS). This prospective, observational, case-controlled study included 43 women with PCOS, and 40 controls. Between day 3 and 5 of the menstrual cycle, fasting serum samples were collected and transvaginal ultrasound was performed. The diagnostic performance of each parameter [total PSA (tPSA), total-to-free PSA ratio (tPSA:fPSA), ovarian volume, ovarian outline] was estimated by means of receiver operating characteristic (ROC) analysis, along with area under the curve (AUC), threshold, sensitivity, specificity as well as positive (+) and negative (-) likelihood ratios (LRs). Multivariate logistical regression models, using ovarian volume and ovarian outline, were constructed. The tPSA and tPSA:fPSA ratio resulted in AUC of 0.74 and 0.70, respectively, with moderate specificity/sensitivity and insufficient LR+/- values. In the multivariate logistic regression model, the combination of ovarian volume and outline had a sensitivity of 97.7% and a specificity of 97.5% in the diagnosis of PCOS, with +LR and -LR values of 39.1 and 0.02, respectively. In women with PCOS, tPSA and tPSA:fPSA ratio have similar diagnostic performance. The use of a multivariate logistic regression model, incorporating ovarian volume and outline, offers very good diagnostic accuracy in distinguishing women with PCOS patients from controls.

Ovarian endometriomas and IVF: a retrospective case-control study

PubMed Central

2011-01-01

We performed this retrospective case-control study analyzing 428 first-attempt in vitro fertilization (IVF) cycles, among which 254 involved women with a previous or present diagnosis of ovarian endometriosis. First, the results of these 254 cycles were compared with 174 cycles involving patients with proven non-endometriotic tubal infertility having similar age and body mass index. Women with ovarian endometriosis had a significantly higher cancellation rate, but similar pregnancy, implantation and delivery rates as patients with tubal infertility. Second, among the women with ovarian endometriosis, the women with a history of laparoscopic surgery for ovarian endometriomas prior to IVF and no visual endometriosis at ovum pick-up (n = 112) were compared with the non-operated women and visual endometriomas at ovum pick-up (n = 142). Patients who underwent ovarian surgery before IVF had significantly shorter period, lower antral follicle count and required higher gonadotropin doses than patients with non-operated endometriomas. The two groups of women with a previous or present ovarian endometriosis did, however, have similar pregnancy, implantation and live birth rates. In conclusion, ovarian endometriosis does not reduce IVF outcome compared with tubal factor. Furthermore, laparoscopic removal of endometriomas does not improve IVF results, but may cause a decrease of ovarian responsiveness to gonadotropins. PMID:21679474

Enhancement of Neoangiogenesis and Follicle Survival by Sphingosine-1-Phosphate in Human Ovarian Tissue Xenotransplants

Ovarian transplantation is one of the key approaches to restoring fertility in women who became menopausal as a result of cancer treatments. A major limitation of human ovarian transplants is massive follicular loss during revascularization. Here we investigated whether sphingosine-1-phosphate or its receptor agonists could enhance neoangiogenesis and follicle survival in ovarian transplants in a xenograft model. Human ovarian tissue xenografts in severe-combined-immunodeficient mice were treated with sphingosine-1-phosphate, its analogs, or vehicle for 1–10 days. We found that sphingosine-1-phosphate treatment increased vascular density in ovarian transplants significantly whereas FTY720 and SEW2871 had the opposite effect. In addition, sphingosine-1-phosphate accelerated the angiogenic process compared to vehicle-treated controls. Furthermore, sphingosine-1-phosphate treatment was associated with a significant proliferation of ovarian stromal cell as well as reduced necrosis and tissue hypoxia compared to the vehicle-treated controls. This resulted in a significantly lower percentage of apoptotic follicles in sphingosine-1-phosphate-treated transplants. We conclude that while sphingosine-1-phosphate promotes neoangiogenesis in ovarian transplants and reduces ischemic reperfusion injury, sphingosine-1-phosphate receptor agonists appear to functionally antagonize this process. Sphingosine-1-phosphate holds great promise to clinically enhance the survival and longevity of human autologous ovarian transplants. PMID:21559342

Female germline or oogonial stem cells transiently residing in fetal ovaries are analogous to the spermatogonial stem cells or germline stem cells (GSCs) in adult testes where GSCs and meiosis continuously renew. Oocytes can be generated in vitro from embryonic stem cells and induced pluripotent stem cells, but the existence of GSCs and neo-oogenesis in adult mammalian ovaries is less clear. Preliminary findings of GSCs and neo-oogenesis in mice and humans have not been consistently reproducible. Monkeys provide the most relevant model of human ovarian biology. We searched for GSCs and neo-meiosis in ovaries of adult monkeys at various ages, and compared them with GSCs from adult monkey testis, which are characterized by cytoplasmic staining for the germ cell marker DAZL and nuclear expression of the proliferative markers PCNA and KI67, and pluripotency-associated genes LIN28 and SOX2, and lack of nuclear LAMIN A, a marker for cell differentiation. Early meiocytes undergo homologous pairing at prophase I distinguished by synaptonemal complex lateral filaments with telomere perinuclear distribution. By exhaustive searching using comprehensive experimental approaches, we show that proliferative GSCs and neo-meiocytes by these specific criteria were undetectable in adult mouse and monkey ovaries. However, we found proliferative nongermline somatic stem cells that do not express LAMIN A and germ cell markers in the adult ovaries, notably in the cortex and granulosa cells of growing follicles. These data support the paradigm that adult ovaries do not undergo germ cell renewal, which may contribute significantly to ovarian senescence that occurs with age. Copyright © 2013 AlphaMed Press.

To investigate the effect of fibroids that do not distort the endometrial cavity on IVF/intracytoplasmic sperm injection (ICSI) outcomes and to identify certain fibroid subgroups that may be deleterious to fertility outcomes. Retrospective cohort study. University-based reproductive medicine center. A total of 10,268 patients undergoing IVF/ICSI between 2009 and 2011 in our unit. Transvaginal ultrasound and hysteroscopy; controlled ovarian hyperstimulation and IVF/ICSI; strict matching criteria. Cycle cancellation, clinical pregnancy, miscarriage, and delivery rates. We included 249 patients with fibroids who underwent IVF/ICSI. Higher day 3 FSH levels were found in women with fibroids compared with in control subjects. No significant differences were found in IVF/ICSI outcomes between the two groups. Patients with intramural fibroids with the largest diameter <2.85 cm or the sum of reported diameters <2.95 cm had a significantly higher delivery rate than patients with larger fibroids. A significant negative effect on delivery rate was noted when intramural fibroids with the largest diameter greater than 2.85 cm were considered, compared with matched controls without fibroids. Our results suggest that although non-cavity-distorting fibroids do not affect IVF/ICSI outcomes, intramural fibroids greater than 2.85 cm in size significantly impair the delivery rate of patients undergoing IVF/ICSI.

Few studies investigated the efficacy and safety of minimally invasive surgery for the treatment of early-stage epithelial ovarian cancer (eEOC). In this context, we aimed to review the current evidence comparing laparoscopy and the laparotomic approach for staging procedures in eEOC. This systematic review was registered in the International Prospective Register of Systematic Reviews. Overall, 3065 patients were included: 1450 undergoing laparoscopy and 1615 undergoing laparotomic staging. Patients undergoing laparoscopy experienced a longer (but not statistically significant) operative time (weighted mean difference [WMD] = 28.3 minutes; 95% confidence interval [CI], -2.59 to 59.2), a lower estimated blood loss (WMD = -156.5 mL; 95% CI, -216.4 to -96.5), a shorter length of hospital stay (WMD = -3.7 days; 95% CI, -5.2 to -2.1), and a lower postoperative complication rate (odds ratio [OR] = 0.48; 95% CI, 0.29-0.81) than patients undergoing laparotomy. The upstaging (OR = 0.81; 95% CI, 0.55-1.20) and cyst rupture (OR = 1.32; 95% CI, 0.52-3.38) rates were similar between groups. Laparoscopic staging is associated with a shorter time to chemotherapy than laparotomic procedures (WMD = -5.16 days; 95% CI, -8.68 to -1.64). Survival outcomes were not influenced by the route of surgery. Pooled data suggested that the minimally invasive surgical approach is equivalent to laparotomy for the treatment of eEOC and may be superior in terms of perioperative outcomes. However, because of the low level of evidence of the included studies, further randomized trials are warranted. Copyright © 2017 AAGL. Published by Elsevier Inc. All rights reserved.

INTRODUCTION In recent years, cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has gained increasing acceptance as a treatment modality for peritoneal carcinomatosis. In female patients, this procedure involves a total hysterectomy and bilateral saphingo-oophorectomy to remove the pelvic peritoneum. We present a case of an unfortunate female adolescent with peritoneal carcinomatosis who underwent cytoreductive surgery and HIPEC. In view of the compelling circumstance, an innovative surgical technique was used to attempt ovarian preservation. PRESENTATION OF CASE A 14 year old girl with carcinoma of the sigmoid colon and peritoneal metastases was offered cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy. In view of her age, ovarian preservation with subcutaneous transposition was performed during cytoreductive surgery. She is currently well 6 months post surgery and has resumed normal menstruation. We review the literature regarding ovarian preservation with subcutaneous transposition and discuss its benefit in pre-menopausal women undergoing peritonectomy and cytoreductive surgery for peritoneal carcinomatosis. DISCUSSION Subcutaneous transposition of the ovary in pre-menopasual patients requiring cytoreductive surgery spares them the sequelae of surgical castration. The subcutaneous location of the transposed ovary conveys advantages such as the ease of ultrasound surveillance and removal in event of disease recurrence. It also retains the possibility of future conception as the transposed ovary can easily be accessed for ovum extraction with assisted reproductive techniques. CONCLUSION Ovarian preservation with subcutaneous transposition is a technique worth considering in the treatment of pre-menopausal women who require cytoreductive surgery for peritoneal carcinomatosis.

How to personalize ovarian stimulation in clinical practice.

Controlled ovarian stimulation (COS) in in vitro fertilization (IVF) cycles is the starting point from which couple's prognosis depends. Individualization in follicle-stimulating hormone (FSH) starting dose and protocol used is based on ovarian response prediction, which depends on ovarian reserve. Anti-Müllerian hormone levels and the antral follicle count are considered the most accurate and reliable markers of ovarian reserve. A literature search was performed for studies that addressed the ability of ovarian reserve markers to predict poor and high ovarian response in assisted reproductive technology cycles. According to the predicted response to ovarian stimulation (poor- normal- or high- response), it is possible to counsel couples before treatment about the prognosis, and also to individualize ovarian stimulation protocols, choosing among GnRH-agonists or antagonists for endogenous FSH suppression, and the FSH starting dose in order to decrease the risk of cycle cancellation and ovarian hyperstimulation syndrome. In this review we discuss how to choose the best COS therapy, based on ovarian reserve markers, in order to enhance chances in IVF.

Senescence is a specific physiological stage of cells characterized by long population doubling time. It accounts for the inability of normal somatic cells to undergo indefinite cell division. As the number of population doublings increase, cell cycle regulatory mechanisms come into play and signal cells to exit the cell cycle and become senescent. Senescence has been implicated in the aging process and may function as a tumor suppressor mechanism in human cells. The ability to measure the degree of cellular senescence is important in understanding the biological processes regulating cell aging and immortalization. Senescent cells exhibit an enzyme termed senescence-associated histochemical staining. Cells immortalized by viral oncogenes often enter a stage of crisis at the early phase of immortalization. The cells at crisis have a long population doubling time. Cells at the crisis stage resemble senescent cells and the expression of SA- beta-Gal may be used to monitor the process of immortalization. In this study the expression profile of SA-beta-Gal was examined in human ovarian surface epithelial cells (HOSE 6-3) undergoing immortalization by the human papilloma viral oncogene E6 and E7 (HPV E6 and E7). Our results showed a low percentage (12.0%) of HOSE 6-3 cells expressing SA-beta-Gal activity at the pre-crisis stage. The percentage of HOSE 6-3 cells expressing SA-beta-Gal activity was highest (39.2%) at the crisis stage. When HOSE 6-3 cells achieved immortalized status there was a sharp decrease in cells (1. 3%) expressing SA-beta-Gal activity. In addition, an inverse relationship between the expression of SA-beta-Gal activity and telomerase activity was noted in cells undergoing immortalization. The results confirm that the SA-beta-Gal enzyme is a good marker for monitoring the population of cells undergoing senescence at different stages of immortalization and that telomerase activation is a characteristic feature of post-crisis cells.

To evaluate the association of the TP53 codon 72 (rs 1042522) alone or in combination with HDM2 SNP309 (rs 2279744) polymorphisms with human infertility and IVF outcome, we collected 1450 infertility women undergoing their first controlled ovarian stimulation for IVF treatment and 250 fertile controls in the case-control study. Frequencies, distribution, interaction of genes, and correlation with infertility and IVF outcome of clinical pregnancy were analyzed. We found a statistically significant association between TP53 codon 72 polymorphism and IVF outcome (52.10% vs. 47.40%, OR = 0.83, 95%CI:0.71-0.96, p = 0.01). No significant difference was shown between TP53 codon 72, HDM2 SNP309 polymorphisms, human infertility, and between the combination of two genes polymorphisms and the clinical pregnancy outcome of IVF. The data support C allele as a protective factor for IVF pregnancy outcome. Further researches should be focused on the mechanism of these associations.

The aim of this study was to evaluate the effectiveness of a distraction-based coping leaflet in reducing distress in women undergoing genetic risk assessment for breast/ovarian cancer. One hundred sixty-two women participated in a randomized controlled trial, receiving either the intervention or standard information. Data were collected through a postal questionnaire at entry into a genetic risk assessment programme and 1 month later. Analysis of covariance revealed a nonsignificant reduction in distress in all women, and a significant reduction of distress among those with high baseline stress, who received the intervention. No gains were found among the control group. Measures of emotional response while thinking about cancer genetic assessment suggested these benefits were achieved in the absence of any rebound emotional response. The intervention offers a low-cost effective coping intervention, which could be integrated into existing services with minimal disruption and may also be appropriate for other periods of waiting and uncertainty.

Pathway modulations and epigenetic alterations in ovarian tumorbiogenesis

Saldanha, Sabita N.; Tollefsbol, Trygve O.

2013-01-01

Cellular pathways are numerous and are highly integrated in function in the control of cellular systems. They collectively regulate cell division, proliferation, survival and apoptosis of cells and mutagenesis of key genes that control these pathways can initiate neoplastic transformations. Understanding these pathways is crucial to future therapeutic and preventive strategies of the disease. Ovarian cancers are of three major types; epithelial, germ-cell and stromal. However, ovarian cancers of epithelial origin, arising from the mesothelium, are the predominant form. Of the subtypes of ovarian cancer, the high-grade serous tumors are fatal, with low survival rate due to late detection and poor response to treatments. Close examination of preserved ovarian tissues and in vitro studies have provided insights into the mechanistic changes occurring in cells mediated by a few key genes. This review will focus on pathways and key genes of the pathways that are mutated or have aberrant functions in the pathology of ovarian cancer. Non-genetic mechanisms that are gaining prominence in the pathology of ovarian cancer, miRNAs and epigenetics, will also be discussed in the review. PMID:24105793

In many cancers, racial and socioeconomic disparities exist regarding the extent of surgery. For ovarian dysgerminoma, fertility-sparing (FS) surgery is recommended whenever possible. The aim of this study was to investigate rates of FS versus non-fertility-sparing (NFS) procedures for stage I ovarian dysgerminoma in adolescents and young adults (AYAs) by ethnicity/race and socioeconomic status. The National Cancer Data Base was queried for patients with ovarian dysgerminoma from 1998 to 2012. After selecting patients aged 15-39 y with stage I disease, a multivariate regression analysis was performed, and rates of FS and NFS procedures were compared, first according to ethnicity/race, and then by socioeconomic surrogate variables. Among the 687 AYAs with stage I ovarian dysgerminoma, there was no significant difference in rates of FS and NFS procedures based on ethnicity/race alone (P = 0.17), but there was a significant difference in procedure type for all three socioeconomic surrogates. The uninsured had higher NFS rates (30%) than those with government (21%) or private (19%) insurance (P = 0.036). Those in the poorest ZIP codes had almost twice the rate of NFS procedures (31%) compared with those in the most affluent ZIP codes (17%). For those in the least-educated regions, 24% underwent NFS procedures compared to 14% in the most-educated areas (P = 0.027). AYAs with stage I ovarian dysgerminoma in lower socioeconomic groups were more likely to undergo NFS procedures than those in higher socioeconomic groups, but there was no difference in rates of FS versus NFS procedures by ethnicity/race. Approaches aimed at reducing socioeconomic disparities require further examination. Copyright © 2017 Elsevier Inc. All rights reserved.

Lampreys diverged from the jawed vertebrate lineage approximately 500million years ago. Lampreys undergo sex differentiation much later than most other vertebrates, and ovarian differentiation occurs several years before testicular differentiation. The genetic basis of lamprey sex differentiation is of particular interest both because of the phylogenetic importance of lampreys and because of their unusual pattern of sex differentiation. As well, differences between parasitic and non-parasitic lampreys may first become evident at ovarian differentiation. However, nothing is known about the genetic basis of ovarian differentiation in lampreys. This study examined potential differences in gene expression before, during, and after ovarian differentiation in parasitic chestnut lamprey Ichthyomyzon castaneus and non-parasitic northern brook lamprey Ichthyomyzonfossor. Eight target genes (17β-hydroxysteroid dehydrogenase, germ cell-less, estrogen receptor β, insulin-like growth factor 1 receptor, daz-associated protein 1, cytochrome c oxidase subunit III, Wilms' tumour suppressor protein 1, and dehydrocholesterol reductase 7) were examined. Northern brook lamprey displayed higher expression of cytochrome c oxidase subunit III, whereas chestnut lamprey displayed higher expression of insulin-like growth factor 1 receptor; these genes may be involved in apoptosis and oocyte growth, respectively. Presumptive male larvae had higher expression of Wilms' tumour suppressor protein 1, which may be involved in the undifferentiated gonad and/or later testicular development. Differentiated females had higher expression of 17β hydroxysteroid dehydrogenase and daz-associated protein 1, which may be involved in female development. This study is the first to identify genes that may be involved in ovarian differentiation and fecundity in lampreys. Copyright © 2014 Elsevier Inc. All rights reserved.

Lynch syndrome is known by healthcare providers mainly for patients with colorectal cancer. Awareness of other associated tumors, such as endometrial or ovarian cancer, is low. This study aimed to analyze the prevalence of Lynch syndrome in unselected patients with endometrial or ovarian cancer. In addition, the willingness of patients and family members to undergo germline mutation testing was investigated. The medical records of all patients diagnosed with endometrial or ovarian cancer at the Department of Gynecology and Obsterics, University Hospital Dresden, between 1998 and 2012, were screened for a family history of HNPCC-associated cancer. Telephone interviews were used to screen, inform, and enroll patients in this genetic analysis study. Molecular analysis was performed by prescreening of tumor tissue, followed by germline mutation analysis. Two hundred and eighty-three patients were diagnosed with endometrial cancer, 291 with ovarian cancer, and 14 with both. A positive family history for tumors associated with Lynch syndrome was documented for 61 patients. Two pathogenic mutations in the genes MLH1 and MSH2 in nine genetic analyses had already been detected before. After genetic counseling, only 10 of 31 index patients (32.3 %) consented for mutation analysis. However, no additional pathogenic heterozygous mutations were found. In this retrospective cohort study in unselected patients with endometrial or ovarian cancer, only a small number of patients with suspected Lynch syndrome could be identified. Of those, acceptance of germline analyses was moderate, only. As a result, the rate of identified pathogenic germline mutations was lower than expected. Therefore, we are convinced that more information on cancer risks, options for predictive molecular testing and preventive procedures, needs to be provided to patients and gynecologists.

Aim To review the current evidence concerning the long-term harmful effects of premature or early menopause, and to discuss some of the clinical implications. Material and methods Narrative review of the literature. Results Women undergoing premature or early menopause, either following bilateral salpingo-oophorectomy or because of primary ovarian insufficiency, experience the early loss of estrogen and other ovarian hormones. The long-term consequences of premature or early menopause include adverse effects on cognition, mood, cardiovascular, bone, and sexual health, as well as an increased risk of early mortality. The use of hormone therapy has been shown to lessen some, although not all of these risks. Therefore, multiple medical societies recommend providing hormone therapy at least until the natural age of menopause. It is important to individualize hormone therapy for women with early estrogen deficiency, and higher dosages may be needed to approximate physiological concentrations found in premenopausal women. It is also important to address the psychological impact of early menopause and to review the options for fertility and the potential need for contraception, if the ovaries are intact. Conclusions Women who undergo premature or early menopause should receive individualized hormone therapy and counseling. PMID:25845383

To compare the effect of the GnRH antagonist/letrozole/gonadotropin protocol with the microdose GnRH agonist flare-up protocol in poor ovarian responders for intracytoplasmic sperm injection. One hundred twenty-one consecutive patients suspected of having or with a history of poor ovarian response between January 2009 and June 2010, who were undergoing ICSI were enrolled. The microdose flareup (MF) protocol was used in 79 patients and the estradiol + progesterone/letrozole + gonadotropin and GnRH antagonist (EP/ALG) protocol was used in 42 patients. Age of the patients, duration of infertility, basal FSH, the total gonadotropin consumption, duration of stimulation, E2 level on the day of hCG administration, the number of embryo transferred, the fertilization rate, implantation rate, clinical pregnancy rate and the live birth rate were not statistically different (p > 0.05). Only the number of oocytes retrieved was significantly higher in the EP/LGA group (1.7 ± 0.7 versus 2.6 ± 0.6). The EP/LGA protocol has no significant improvement against the microdose flare-up protocol in poor responder patients.

Abstract Rationale: The standard treatment for ovarian cancer is chemotherapy with 2 drugs (taxanes and platinum drugs). However, the traditional combination of the 2 drugs has many adverse effects (AEs) and the cancer cells will quickly become resistant to the drugs. Apatinib is a small-molecule antiangiogenic agent which has shown promising therapeutic effects against diverse tumor types, but it still remains unknown whether apatinib has an antitumor effect in patients with ovarian cancer. Herein, we present a successfully treated case of ovarian cancer using chemotherapy and apatinib, in order to demonstrate the effectiveness of this new combined regimen in ovarian cancer. Patients concerns: A 51-year-old Chinese woman presented with ovarian cancer >4.5 years. The disease and the cancer antigen 125 (CA-125) had been controlled well by surgical treatment and following chemotherapy. However, the drugs could not control the disease anymore as the CA-125 level was significantly increasing. Diagnosis: Ovarian cancer. Interventions: The patient was treated with apatinib combined with epirubicin. Apatinib was administered orally, at an initial daily dose of 500 mg, and was then reduced to 250 mg qd after the appearance of intolerable hand–foot syndrome (HFS) and oral ulcer. Then, the oral ulcer disappeared and the HFS was controlled by dose adjustment, oral vitamin B6, and hand cream application. Outcomes: The CA-125 reverted to the normal value after treatment with the new regimen. Magnetic resonance imaging showed that the original tumor lesions had disappeared. Apatinib monotherapy as maintenance therapy was then used to successfully control the cancer with a complete response. Our study is the first, to our knowledge, to report the therapeutic effects of apatinib and epirubicin on ovarian cancer. Lessons: Apatinib combined with chemotherapy and apatinib monotherapy as maintenance therapy could be a new therapeutic strategy for ovarian cancer, especially adenocarcinomas. PMID:29137078

Purpose Chemotherapy-induced amenorrhea is a serious concern for women undergoing cancer therapy. This prospective randomized trial evaluated the use of gonadotropin-releasing hormone (GnRH) analog triptorelin to preserve ovarian function in women treated with chemotherapy for early-stage breast cancer. Patients and Methods Premenopausal women age 44 years or younger were randomly assigned to receive either triptorelin or no triptorelin during (neo)adjuvant chemotherapy and were further stratified by age (< 35, 35 to 39, > 39 years), estrogen receptor status, and chemotherapy regimen. Objectives included the resumption of menses and serial monitoring of follicle-stimulating hormone (FSH) and inhibin A and B levels. Results Targeted for 124 patients with a planned 5-year follow-up, the trial was stopped for futility after 49 patients were enrolled (median age, 39 years; range, 21 to 43 years); 47 patients were treated according to assigned groups with four cycles of adriamycin plus cyclophosphamide alone or followed by four cycles of paclitaxel or six cycles of fluorouracil, epirubicin, and cyclophosphamide. Menstruation resumed in 19 (90%) of 21 patients in the control group and in 23 (88%) of 26 in the triptorelin group (P= .36). Menses returned after a median of 5.8 months (range, 1 to 19 months) after completion of chemotherapy in the triptorelin versus 5.0 months (range, 0 to 28 months) in the control arm (P= .58). Two patients (age 26 and 35 years at random assignment) in the control group had spontaneous pregnancies with term deliveries. FSH and inhibin B levels correlated with menstrual status. Conclusion When stratified for age, estrogen receptor status, and treatment regimen, amenorrhea rates on triptorelin were comparable to those seen in the control group. PMID:22231041

To determine whether HA-CMC was associated with the development of postoperative intra-abdominal collections in patients undergoing laparotomy for ovarian, fallopian tube, or primary peritoneal malignancies. We retrospectively identified all laparotomies performed for these malignancies from March 1, 2005 to December 31, 2007. The use of HA-CMC was identified. Laparotomies for malignant bowel obstruction or repair of fistulae were excluded. Intra-abdominal collections, non-infected and infected, were defined as localized intraperitoneal fluid accumulations in the absence of re-accumulating ascites. All other complications were also captured. Appropriate statistical tests were applied using SPSS 15.0. We identified 219 laparotomies with HA-CMC and 204 without HA-CMC. Upper abdominal resections were performed in 65/219 (30%) HA-CMC cases compared to 39/204 (19%) cases without HA-CMC (P=0.01). The rates of large bowel and/or rectal resections were similar in both cohorts. Intra-abdominal collections were seen in 18/219 (8.2%) HA-CMC cases compared to 5/204 (2.5%) cases without HA-CMC (P=0.009). HA-CMC was independently associated with the diagnosis of a postoperative intra-abdominal collection (P=0.01). All but 2 collections developed in patients undergoing debulking procedures. HA-CMC appears to be associated with a higher rate of postoperative intra-abdominal collections. This seems to be greatest in patients who are undergoing a debulking procedure.

Epithelial ovarian cancer is the most lethal gynecological malignancy and the fifth leading cause of cancer deaths in women in the Western world. ETS transcription factors are known to act as positive or negative regulators of the expression of genes that are involved in various biological processes, including those that control cellular proliferation, differentiation, apoptosis, tissue remodeling, angiogenesis and transformation. ETV5 belongs to the PEA3 subfamily. PEA3 subfamily members are able to activate the transcription of proteases, matrix metalloproteinases and tissue inhibitor of metalloproteases, which is central to both tumor invasion and angiogenesis. Here, we examined the role of the ETV5 transcription factor in epithelial ovarian cancer and we found ETV5 was upregulated in ovarian tumor samples compared to ovarian tissue controls. The in vitro inhibition of ETV5 decreased cell proliferation in serum-deprived conditions, induced EMT and cell migration and decreased cell adhesion to extracellular matrix components. ETV5 inhibition also decreased cell-cell adhesion and induced apoptosis in anchorage-independent conditions. Accordingly, upregulation of ETV5 induced the expression of cell adhesion molecules and enhanced cell survival in a spheroid model. Our findings suggest that the overexpression of ETV5 detected in ovarian cancer cells may contribute to ovarian tumor progression through the ability of ETV5 to enhance proliferation of ovarian cancer cells. In addition, upregulation of ETV5 would play a role in ovarian cancer cell dissemination and metastasis into the peritoneal cavity by protecting ovarian cancer cells from apoptosis and by increasing the adhesion of ovarian cancer cells to the peritoneal wall through the regulation of cell adhesion molecules.

Our objective was to evaluate the effect of the COX-2 inhibitor, celecoxib, on (1) proliferation and apoptosis in human ovarian cancer cell lines and primary cultures of ovarian cancer cells, and (2) inhibition of tumor growth in a genetically engineered mouse model of serous ovarian cancer under obese and non-obese conditions. Celecoxib inhibited cell proliferation in three ovarian cancer cell lines and five primary cultures of human ovarian cancer after 72 hours of exposure. Treatment with celecoxib resulted in G1 cell cycle arrest, induction of apoptosis, inhibition of cellular adhesion and invasion and reduction of expression of hTERT mRNA and COX-2 protein in all of the ovarian cancer cell lines. In the KpB mice fed a high fat diet (obese) and treated with celecoxib, tumor weight decreased by 66% when compared with control animals. Among KpB mice fed a low fat diet (non-obese), tumor weight decreased by 46% after treatment with celecoxib. In the ovarian tumors from obese and non-obese KpB mice, treatment with celecoxib as compared to control resulted in decreased proliferation, increased apoptosis and reduced COX-2 and MMP9 protein expression, as assessed by immunohistochemistry. Celecoxib strongly decreased the serum level of VEGF and blood vessel density in the tumors from the KpB ovarian cancer mouse model under obese and non-obese conditions. This work suggests that celecoxib may be a novel chemotherapeutic agent for ovarian cancer prevention and treatment and be potentially beneficial in both obese and non-obese women.

Chemotherapy targets rapidly dividing tissues in the body. It destroys the progenitor cells in gonads resulting in premature ovarian failure. Studies have suggested that bone marrow-derived stem cells can generate oocytes in chemotherapy treated female rats after transplantation. The present study aimed to assess mechanism of homing, the action of injected BM-MSCs on ovarian function after ovarian damage. Seventy two female albino rats were randomly allocated into Control and CTX group, The Experimental protocol was lasted for 12 weeks during which serum FSH and E2 were monitored twice at the end of the 2nd week (12 rats) and 8th week (6 rats). Stem cells identification and homing were evaluated by Flowcytometry and tagging of stem cells with iron oxide particles respectively. Also, histopathological examination was done to evaluate both degeneration (6 rats at 4th week) and regeneration (6 rats at 12th week) of ovarian tissue together with assessment of the levels of TNF-α in ovarian homogenate and IGF-I as a growth factor in ovarian tissue. Partial improvement of E2 and FSH levels as well as ovarian architecture. Elevation of ovarian TNF- α levels and of IGF-I immunohistochemical expressions in ovarian tissues of BM-MSCs injected rats were noticed following homing of BM- MSCs in the ovarian stroma in both control and chemotherapy groups. Injected BM- MSCs can home in the stroma of the injured ovaries. IGF-I and TNF- α may have a role in the attraction of stem cells in vivo. © 2016 Wiley Periodicals, Inc.

We hypothesized that (i) preclinical biologic evidence exists for the role of androgens in ovarian cancer development and (ii) flutamide treatment of women at high risk for ovarian cancer may identify meaningful tissue biomarkers of androgen action and of ovarian cancer initiation. We showed that androgen ablation of male mice led to a 24-fold decrease in tumor burden from serous ovarian cells. In a phase II study, we studied the effect of preoperative flutamide treatment (125 mg/day × 6 weeks) in 12 women versus 47 controls, 47% with BRCA mutation. We analyzed immunohistochemical scores of candidate proteins CSF-1, CSF-1R, and ErbB4 in the epithelium and stroma of fallopian tube, ovary, and ovarian endosalpingiosis. Flutamide decreased the levels, notably, of CSF-1 and ErbB4 in ovarian stroma (P ≤ 0.0006) and ovarian endosalpingiosis (P ≤ 0.01), ErbB4 in ovarian epithelium (P = 0.006), and CSF-1R in ovarian endosalpingiosis (P = 0.009). Our logistic regression model clearly distinguished the flutamide patients from controls (P ≤ 0.0001). Our analysis of the precision of this model of CSF-1 and ErbB4 expression in ovarian stroma achieved 100% sensitivity and 97% specificity (AUC = 0.99). Thus, our data suggest that a short 6-week exposure of flutamide reversed elevated levels of CSF-1 and ErbB4 (both of which we had previously found correlated with high risk status). CSF-1 and ErbB4 in ovarian stroma led to a model with high predictive value for flutamide sensitivity.

Medroxyprogesterone acetate (Provera) is a drug that is commonly given to young women with cancer during chemotherapy and radiation to control heavy bleeding associated with anovulation. Because hypothalamic-pituitary-ovarian suppression has been associated with ovarian protection from the effects of chemotherapy and medroxyprogesterone acetate has been identified as a radiosensitizing agent, we explored the effects of medroxyprogesterone acetate on a rat model with known radiation injury characteristics. Sprague-Dawley rats were treated with medroxyprogesterone acetate or vehicle from day 22 to day 37 of life and were either irradiated or sham-irradiated on day 30 of life and then killed on day 44.more » Radiation with medroxyprogesterone acetate administration produced a greater loss in preantral and healthy control follicles than in control follicles. No suppression of luteinizing hormone or follicle-stimulating hormone had occurred by day 30 but ovarian glutathione content was reduced. These findings indicate that the administration of medroxyprogesterone acetate with radiotherapy may enhance ovarian injury.« less

To evaluate the effects of letrozole and cabergoline in a rat model of ovarian hyperstimulation syndrome (OHSS). In this prospective, controlled experimental study, the 28 female Wistar rats were divided into four subgroups (one non-stimulated control and three OHSS-positive groups: placebo, letrozole, and cabergoline). To induce OHSS, rats were injected with 10 IU of pregnant mare serum gonadotropin from day 29 to day 32 of life, followed by subcutaneous injection of 30 IU hCG on day 33. Letrozole rats received with a single dose of 0.1 mg/kg letrozole via oral gavage, on the hCG day. Cabergoline rats received with a single dose of 100 µg/kg cabergoline via oral gavage, on the hCG day. All animals were compared in terms of body weight, vascular permeability (VP), ovarian diameter, ovarian tissue VEGF expression (assessed via immunohistochemical staining), and blood pigment epithelium-derived growth factor (PEDF) levels. The OHSS-positive placebo group (group 2) exhibited the highest VP, ovarian diameter, extent of VEGF staining, and lowest PEDF level, as expected. No significant difference was evident between the letrozole and cabergoline groups in terms of any of body weight; VP; PEDF level; ovarian diameter; or the staining intensity of, or percentage staining for, VEGF in ovarian tissues. Letrozole and cabergoline were equally effective to prevent OHSS, reducing the ovarian diameter, VP, and PEDF and VEGF levels to similar extents.

Controlled ovarian stimulation (COS) is crucial for optimizing in vitro fertilization (IVF) / intracytoplasmic sperm injection (ICSI) success. Multiple factors influence the ovarian response to COS, making predictions about oocyte yields not so straightforward. As a result, the ovarian response may be poor or suboptimal, or even excessive, all of which have negative consequences for the affected patient. There is a group of patients that present with a suboptimal response to COS despite normal biomarkers of ovarian reserve, such as AFC and AMH. These patients have a lower number of retrieved oocytes than what was expected based on their ovarian reserve, thus showing the inadequacy of using only the traditional ovarian reserve biomarkers to predict the ovarian response. Suboptimal response to COS might be related to ovarian sensitivity to exogenous gonadotropins modulated by genetic factors. The understanding of the gene polymorphisms related to reproductive function can help to improve the clinical management of this patient population and to explain some of the individual patient variability in response to COS. The development of a pharmacogenetic approach concerning COS in the context of assisted reproduction seems attractive as it might help to understand the relationship between genetic variants and ovarian response to exogenous gonadotropins. The patient ́s genetic profile could be used to select the most appropriate gonadotropin type, predict the optimal dosage for each drug, develop a cost-effective treatment plan, maximize the success rates, and lastly, decrease the time-to-pregnancy.

This study investigated the ovarian control of LH responsiveness to GnRH in anovulatory women with the polycystic ovary syndrome (PCOS). It is suggested that the enhanced pituitary sensitivity of LH secretion to GnRH in anovulatory women with PCOS is not due to a reduced production but rather to a defect in the interaction of ovarian factors on the hypothalamic-pituitary system.

Because inherited BRCA1 or BRCA2 mutations strikingly increase ovarian cancer risk, polymorphisms in these genes could represent low penetrance susceptibility alleles. Previous studies of the BRCA2 N372H polymorphism suggested that HH homozygotes have a modestly increased risk of both breast and ovarian cancer. We have examined whether BRCA2 N372H or common amino acid-changing polymorphisms in BRCA1 predispose to ovarian cancer. A population-based, case control study of ovarian cancer was performed in North Carolina. Cases included 312 women with ovarian cancer (76% invasive and 24% borderline) and 401 age- and race-matched controls. Blood DNA from subjects was genotyped for BRCA2 N372H and BRCA1 Q356R and P871L. There was no association between BRCA2 N372H and risk of borderline or invasive epithelial ovarian cancer. The overall odds ratio (OR) for HH homozygotes was 0.8 [95% confidence interval (CI) = 0.4-1.5] and was similar in all subsets, including invasive serous cases. In addition, neither the BRCA1 Q356R (OR = 0.9, 95% CI 0.5-1.4) nor P871L (OR = 0.9, 95% CI 0.6-1.9) polymorphisms were associated with ovarian cancer risk. There was a significant racial difference in allele frequencies of the P871L polymorphism (P = 0.64 in Caucasians, L = 0.76 in African-Americans, P < 0.0001). In this population-based, case control study, common amino acid changing BRCA1 and 2 polymorphisms were not found to affect the risk of developing ovarian cancer.

The experiment was conducted to determine the most effective antioxidant (among the vitamin E (VE), vitamin C (VC), vitamin A (VA), astaxanthine (AX), β-carotene (βC)) on the ovarian egg number and size, level of VE, VC, VA, AX, βC and oxidative stress (as malondialdehyde (MDA)) in the hepatopancreas, ovarian, gills and muscle tissue during ovarian development of Astacus leptodactylus. One control (C) and five experimental diets (EE, EC, EA, EAX and EβC) were prepared. The EE, EC, EA, EAX and EβC groups were formed by added 150 mg kg-1 VE, 200 mg kg-1 VC, 240 mg kg-1 VA, 200 mg kg-1 AX and 200 mg kg-1 βC to diet C, respectively. At the end of the experiment found that the dietary antioxidants increased ovarian egg number and size and reduced the level of MDA in the tissues. Ovarian egg number and size were highest in the EE and EAX diet groups in the comparison to control (p<0.001). The level of MDA in the tissues was lowest in the EAX diet group in the comparison to control (p<0.001). The highest levels of VE, VC, VA, AX and βC were found in the hepatopancreas and ovarian compared with muscle and gills. The highest level of MDA also was determined in the ovarian according to other tissues. In conclusion, the VE and AX in broodstock diets were the most effective antioxidants on the ovarian egg number and size of A. leptodactylus.

4-Vinylcyclohexene diepoxide (VCD) destroys ovarian primordial and small primary follicles via apoptosis. In mice, VCD exposure induces ovarian mRNA expression of glutathione S-transferase (GST) family members, including isoform mu (Gstm). Extra-ovarian GSTM negatively regulates pro-apoptotic apoptosis signal-regulating kinase 1 (ASK1) through protein complex formation, which dissociates during stress, thereby initiating ASK1-induced apoptosis. The present study investigated the ovarian response of Gstm mRNA and protein to VCD. Induction of Ask1 mRNA at VCD-induced follicle loss onset was determined. Ovarian GSTM:ASK1 protein complex formation was investigated and VCD exposure effects thereon evaluated. Phosphatidylinositol-3 kinase (PI3K) regulation of GSTM protein was also studied.more » Postnatal day (PND) 4 rat ovaries were cultured in control media ± 1) VCD (30 μM) for 2–8 days; 2) VCD (30 μM) for 2 days, followed by incubation in control media for 4 days (acute VCD exposure); or 3) LY294002 (20 μM) for 6 days. VCD exposure did not alter Gstm mRNA expression, however, GSTM protein increased (P < 0.05) after 6 days of both the acute and chronic treatments. Ask1 mRNA increased (0.33-fold; P < 0.05) relative to control after 6 days of VCD exposure. Ovarian GSTM:ASK1 protein complex formation was confirmed and, relative to control, the amount of GSTM bound to ASK1 increased 33% (P < 0.05) by chronic but with no effect of acute VCD exposure. PI3K inhibition increased (P < 0.05) GSTM protein by 40% and 71% on d4 and d6, respectively. These findings support involvement of GSTM in the ovarian response to VCD exposure, through regulation of pro-apoptotic ASK1. - Highlights: ► GSTM protein increases in response to ovarian VCD exposure. ► VCD increases Ask1 mRNA at the onset of follicle loss. ► Ovarian GSTM binds more ASK1 protein during VCD-induced ovotoxicity. ► PI3K regulates ovarian GSTM protein.« less

The BRCA2 372 HH genotype defined by the BRCA2 N372H nonconservative amino acid substitution polymorphism was recently reported to be associated with a small increased risk of breast cancer. We investigated whether this polymorphism was associated with ovarian cancer risk by conducting British and Australian case-control comparisons in parallel, including a total sample of 1,121 ovarian cancer cases and 2,643 controls. There was no difference in genotype frequency between control groups from the 2 studies (p = 0.9). The HH genotype was associated with an increased risk of ovarian cancer in both studies, and the risk estimate for the pooled studies was 1.36 (95% CI 1.04-1.77, p = 0.03). There was also a suggestion that this risk may be greater for ovarian cancers of the serous subtype for both studies, with an OR (95% CI) of 1.66 (1.17-2.54) for the 2 studies combined (p = 0.005). The BRCA2 372 HH genotype appears to be associated with an increased risk of ovarian cancer of a similar magnitude to that reported for breast cancer. Copyright 2002 Wiley-Liss, Inc.

Despite advances in surgical aggressiveness and conventional chemotherapy, ovarian cancer remains the most lethal cause of gynecologic cancer mortality; consequently there is a need for new therapeutic agents and innovative treatment paradigms for the treatment of ovarian cancer. Several studies have demonstrated that ovarian cancer is an immunogenic disease and immunotherapy represents a promising and novel approach that has not been completely evaluated in ovarian cancer. Our objective was to evaluate the anti-tumor activity of an oncolytic herpes simplex virus "armed" with murine interleukin-12 and its ability to elicit tumor-specific immune responses. We evaluated the ability of interleukin-12-expressing and control oncolytic herpes simplex virus to kill murine and human ovarian cancer cell lines in vitro. We also administered interleukin-12-expressing oncolytic herpes simplex virus to the peritoneal cavity of mice that had developed spontaneous, metastatic ovarian cancer and determined overall survival and tumor burden at 95 days. We used flow cytometry to quantify the tumor antigen-specific CD8 + T cell response in the omentum and peritoneal cavity. All ovarian cancer cell lines demonstrated susceptibility to oncolytic herpes simplex virus in vitro. Compared to controls, mice treated with interleukin-12-expressing oncolytic herpes simplex virus demonstrated a more robust tumor antigen-specific CD8 + T-cell immune response in the omentum (471.6 cells vs 33.1 cells; p = 0.02) and peritoneal cavity (962.3 cells vs 179.5 cells; p = 0.05). Compared to controls, mice treated with interleukin-12-expressing oncolytic herpes simplex virus were more likely to control ovarian cancer metastases (81.2 % vs 18.2 %; p = 0.008) and had a significantly longer overall survival (p = 0.02). Finally, five of 6 mice treated with interleukin-12-expressing oHSV had no evidence of metastatic tumor when euthanized at 6 months, compared to two of 4 mice treated with sterile phosphate buffer solution. Our pilot study demonstrates that an interleukin-12-expressing oncolytic herpes simplex virus effectively kills both murine and human ovarian cancer cell lines and promotes tumor antigen-specific CD8 + T-cell responses in the peritoneal cavity and omentum, leading to reduced peritoneal metastasis and improved survival in a mouse model.

Insulin has a biphasic effect on the ability of human chorionic gonadotropin to induce ovarian cysts in the rat.

Hyperinsulinemia enhances the ability of subovulatory doses of human chorionic gonadotropin (hCG) to induce ovarian follicular cysts in the rat. To determine the relative contribution of these hormones to the development of ovarian cysts, adult female rats were treated with either (1) vehicle alone (controls), (2) a high-fat diet (HFD) to control for the effects of weight gain, (3) 1.5 to 6 IU hCG twice daily plus 6 U insulin (Ins)/d, or (4) 1.5 to 9 U Ins/d plus 3 IU hCG twice daily. On day 23 of the in vivo treatments, all groups that received at least 6 U Ins/d displayed increased body weight compared with control and HFD rats (P < or = .05). No control rats and only one HFD rat displayed ovarian cysts on this day. Plasma estrone (E1) and androstenedione (A4) were elevated in HFD rats with noncystic follicles compared with control rats (P < or = .05). Between 64% and 80% of rats on 6 U Ins/d plus twice-daily injections of 1.5 to 6 IU hCG displayed ovarian cysts on day 23. Plasma estradiol (E2) concentrations for these treatment groups were similar to those of control rats. Of the hormonally treated animals, only those that had ovarian cysts in response to twice-daily injections of 4.5 or 6 IU hCG plus 6 U Ins/d displayed elevated plasma A4 and/or testosterone compared with controls. In contrast, plasma E1 concentrations were elevated on day 23 for animals bearing ovarian cysts in response to increasing doses of hCG plus the fixed dose of 6 U Ins/d. Between 70% and 80% of rats treated twice daily with 3 IU hCG plus a daily dose of 1.5 to 6 U Ins displayed ovarian cysts on day 23. In marked contrast, only 25% of rats treated with this dose of hCG plus 9 U Ins/d developed cystic follicles. Of the plasma steroids tested, only E1 and A4 were elevated in these treatment groups compared with controls. However, these increases in plasma steroid concentrations did not correlate with the dose of insulin. We conclude from these data that, although the mechanisms remain to be elucidated, extreme hyperinsulinemia has the paradoxical ability to attenuate the induction of ovarian cysts by hCG in some animals.

Two independent ovarian cancer cell lines and fibroblast controls were treated with nonequilibrium atmospheric pressure plasma (NEAPP). Most ovarian cancer cells were detached from the culture dish by continuous plasma treatment to a single spot on the dish. Next, the plasma source was applied over the whole dish using a robot arm. In vitro cell proliferation assays showed that plasma treatments significantly decreased proliferation rates of ovarian cancer cells compared to fibroblast cells. Flow cytometry and western blot analysis showed that plasma treatment of ovarian cancer cells induced apoptosis. NEAPP could be a promising tool for therapy for ovarian cancers.

To evaluate anti-Müllerian hormone (AMH) concentrations and antral follicle counts (AFCs) in the prediction of pregnancy outcomes after controlled ovarian stimulation among women undergoing intrauterine insemination. A retrospective study included women with unexplained infertility aged 41years or younger who attended a fertility clinic in Italy between December 2009 and May 2014. Ovarian stimulation was achieved with recombinant follicle-stimulating hormone or highly purified human menopausal gonadotropin. Receiver operating characteristic curves were generated to predict ongoing pregnancy. The primary outcome was the association between AMH/AFC and ongoing pregnancy, and was assessed by logistic regression. Overall, 276 women were included, of whom 43 (15.6%) achieved ongoing pregnancy. Multivariate analysis showed that women with a serum day-3 concentration of AMH higher than 2.3ng/mL were more likely to have ongoing pregnancy than were those with a concentration lower than 2.3ng/mL (odds ratio 5.84, 95% confidence interval 2.38-14.31; P<0.001). No associations were recorded for AFCs. AMH should be used to predict the pregnancy outcome of intrauterine insemination. Copyright © 2015 International Federation of Gynecology and Obstetrics.

Cigarette smoking may affect each of the currently proposed mechanisms of ovarian carcinogenesis. Whether cigarette smoking has any effect on the development of ovarian cancer has not been adequately evaluated. To study this issue, the authors examined data from the Cancer and Steroid Hormone Study, a multicenter, case-control study of gynecologic cancers conducted between December 1, 1980, and December 31, 1982, in eight geographic areas of the United States. This analysis utilized data on 494 women with newly diagnosed epithelial ovarian cancer and 4,238 population-based control women 20-54 years of age. There was no association of epithelial ovarian cancer with dose of cigarette smoking, age smoking started, time since smoking started, or time since smoking last occurred. Simultaneous adjustment for age, parity, history of oral contraceptive use, and other potentially confounding factors did not alter these results.

To investigate the effect of enoxaparin on ovarian reserve and serum antimüllerian hormone (AMH) levels in a rat ovarian torsion model. Experimental study. Experimental surgery laboratory in a training and research hospital. Fourteen female Wistar Hannover rats. 1) Control group received no special treatment other than abdominal exposure; 2) detorsion-only group received bilateral adnexal torsion (3-hour ischemia), and then after 3-hour torsion period, detorsion (reperfusion) was performed; and 3) detorsion-enoxaparin group received 0.5 mg/kg enoxaparin subcutaneously 2 hours before the same surgery as the detorsion-only group and a second 0.5 mg/kg dose of enoxaparin 24 hours after the first surgeries. Apart from the surgeries, preoperative and postoperative 1-mL blood samples were drawn from the right jugular vein of each rat. Preoperative and postoperative serum AMH levels, histopathologic damage scores, and follicle counts in the ovarian tissue of the rats. Vascular congestion and hemorrhage scores were higher in the detorsion-enoxaparin group than in the detorsion-only and control groups. The number of small antral follicles was smaller in the detorsion-only group than in the control group. The difference in the pre- and postoperative AMH levels was higher in the detorsion-only group than in the control and detorsion-enoxaparin groups. The combination of enoxaparin therapy with conventional ovarian detorsion is more effective in protecting the ovarian reserve than detorsion alone.

Epidemiological studies of the impact of environmental chemicals on reproductive health demonstrate consequences of exposure but establishing causative links requires animal models using ‘real life’ in utero exposures. We aimed to determine whether prolonged, low-dose, exposure of pregnant sheep to a mixture of environmental chemicals affects fetal ovarian development. Exposure of treated ewes (n = 7) to pollutants was maximized by surface application of processed sewage sludge to pasture. Control ewes (n = 10) were reared on pasture treated with inorganic fertilizer. Ovaries and blood were collected from fetuses (n = 15 control and n = 8 treated) on Day 110 of gestation for investigation of fetal endocrinology, ovarian follicle/oocyte numbers and ovarian proteome. Treated fetuses were 14% lighter than controls but fetal ovary weights were unchanged. Prolactin (48% lower) was the only measured hormone significantly affected by treatment. Treatment reduced numbers of growth differentiation factor (GDF9) and induced myeloid leukaemia cell differentiation protein (MCL1) positive oocytes by 25–26% and increased pro-apoptotic BAX by 65% and 42% of protein spots in the treated ovarian proteome were differently expressed compared with controls. Nineteen spots were identified and included proteins involved in gene expression/transcription, protein synthesis, phosphorylation and receptor activity. Fetal exposure to environmental chemicals, via the mother, significantly perturbs fetal ovarian development. If such effects are replicated in humans, premature menopause could be an outcome.

Several genetic variants have been validated as risk factors for ovarian cancer. Endometriosis has also been described as a risk factor for ovarian cancer. Identifying genetic risk factors that are common to the two diseases might help improve our understanding of the molecular pathogenesis potentially linking the two conditions. In a hospital-based case-control analysis, 12 single nucleotide polymorphisms (SNPs), validated by the Ovarian Cancer Association Consortium (OCAC) and the Collaborative Oncological Gene-environment Study (COGS) project, were genotyped using TaqMan® OpenArray™ analysis. The cases consisted of patients with endometriosis, and the controls were healthy individuals without endometriosis. A total of 385 cases and 484 controls were analyzed. Odds ratios and P values were obtained using simple logistic regression models, as well as from multiple logistic regression models with adjustment for clinical predictors. rs11651755 in HNF1B was found to be associated with endometriosis in this case-control study. The OR was 0.66 (95% CI, 0.51 to 0.84) and the P value after correction for multiple testing was 0.01. None of the other genotypes was associated with a risk for endometriosis. As rs11651755 in HNF1B modified both the ovarian cancer risk and also the risk for endometriosis, HNF1B may be causally involved in the pathogenetic pathway leading from endometriosis to ovarian cancer.

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder characterized by chronic anovulation, hyperandrogenism, polycystic ovary morphology (PCOM) and metabolic disturbances including insulin resistance and type 2 diabetes mellitus. Although insulin resistance could be associated with PCOM, recent studies have shown controversial results. The aim of this study was to determine the relationship between PCOM and insulin resistance. This was a cross-sectional clinical study. A total of 679 women with PCOS who were diagnosed using the National Institute of Child Health and Human Disease (NICHD) criteria and 272 control women were analysed. We measured fasting glucose and insulin levels, 75 g oral glucose tolerance test-derived glucose and insulin levels, testosterone levels, ovarian volume and follicle number. Polycystic ovary morphology was described in 543 women (80.0%) with PCOS. Women with PCOS had significantly higher 2 hours postload glucose, fasting and 2 hours postload insulin levels, ovarian volume, ovarian follicle numbers and lower insulin sensitivity compared with those of the controls (all P<.01). In women with PCOS, ovarian volume and ovarian follicle number were negatively associated with the quantitative insulin sensitivity check index after adjusting for age, body mass index and total testosterone; however, this association was not observed in the controls. In the logistic regression analysis, increased ovarian follicle number was associated with decreased insulin sensitivity in women with PCOS. In PCOS, enlarged ovarian volume and follicle excess were associated with insulin resistance, and the number of ovarian follicles could be a predictor of insulin resistance. © 2017 John Wiley & Sons Ltd.

To establish the research model of ovarian carcinoma in nude mice, and to explore the effect of Paris Phyllin VII combined with silica nano complex on the inhibition and the antioxidant ability of ovarian carcinoma in nude mice. Nude mice models with ovarian carcinoma were established by axillary subcutaneous inoculation of human SKOV3/DDP resistant ovarian cancer cell 200 µl and were used in the experiment. Treating the nude mice with Paris Phyllin VII combined with silica nano complex by gavage for 15 days to observe the weight change of the nude mice, tumor inhibition effect and changes of serum antioxidant capacity. Compared with the negative control group, tumor inhibition rate increased significantly in Paris Phyllin VII combined with silica nano complex treatment group, and was higher than that in both Paris Phyllin VII treatment only and silica nano composites treatment only group. The serum superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) level of Paris Phyllin VII combined with silica nano complex treatment group was significantly higher than that of control group, Paris Phyllin VII treatment only and silica nano composites treatment only group. The serum malonaldehyde (MDA) level of Paris Phyllin VII combined with silica nano complex treatment group was significantly lower than that of the negative control group. Paris Phyllin VII combined with silica nano complex treatment can inhibit the ovarian carcinoma in nude mice, which may mediate by the enhancement of antioxidant capability in nude mice with ovarian cancer.

To compare the effectiveness of in vitro fertilisation with single embryo transfer or in vitro fertilisation in a modified natural cycle with that of intrauterine insemination with controlled ovarian hyperstimulation in terms of a healthy child. Multicentre, open label, three arm, parallel group, randomised controlled non-inferiority trial. 17 centres in the Netherlands. Couples seeking fertility treatment after at least 12 months of unprotected intercourse, with the female partner aged between 18 and 38 years, an unfavourable prognosis for natural conception, and a diagnosis of unexplained or mild male subfertility. Three cycles of in vitro fertilisation with single embryo transfer (plus subsequent cryocycles), six cycles of in vitro fertilisation in a modified natural cycle, or six cycles of intrauterine insemination with ovarian hyperstimulation within 12 months after randomisation. The primary outcome was birth of a healthy child resulting from a singleton pregnancy conceived within 12 months after randomisation. Secondary outcomes were live birth, clinical pregnancy, ongoing pregnancy, multiple pregnancy, time to pregnancy, complications of pregnancy, and neonatal morbidity and mortality 602 couples were randomly assigned between January 2009 and February 2012; 201 were allocated to in vitro fertilisation with single embryo transfer, 194 to in vitro fertilisation in a modified natural cycle, and 207 to intrauterine insemination with controlled ovarian hyperstimulation. Birth of a healthy child occurred in 104 (52%) couples in the in vitro fertilisation with single embryo transfer group, 83 (43%) in the in vitro fertilisation in a modified natural cycle group, and 97 (47%) in the intrauterine insemination with controlled ovarian hyperstimulation group. This corresponds to a risk, relative to intrauterine insemination with ovarian hyperstimulation, of 1.10 (95% confidence interval 0.91 to 1.34) for in vitro fertilisation with single embryo transfer and 0.91 (0.73 to 1.14) for in vitro fertilisation in a modified natural cycle. These 95% confidence intervals do not extend below the predefined threshold of 0.69 for inferiority. Multiple pregnancy rates per ongoing pregnancy were 6% (7/121) after in vitro fertilisation with single embryo transfer, 5% (5/102) after in vitro fertilisation in a modified natural cycle, and 7% (8/119) after intrauterine insemination with ovarian hyperstimulation (one sided P=0.52 for in vitro fertilisation with single embryo transfer compared with intrauterine insemination with ovarian hyperstimulation; one sided P=0.33 for in vitro fertilisation in a modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation). In vitro fertilisation with single embryo transfer and in vitro fertilisation in a modified natural cycle were non-inferior to intrauterine insemination with controlled ovarian hyperstimulation in terms of the birth of a healthy child and showed comparable, low multiple pregnancy rates.Trial registration Current Controlled Trials ISRCTN52843371; Nederlands Trial Register NTR939. © Bensdorp et al 2015.

Mutations at the ovarian tumor (otu) gene of Drosophila melanogaster cause female sterility and generate a range of ovarian phenotypes. Quiescent (QUI) mutants exhibit reduced germ cell proliferation; in oncogenic (ONC) mutants germ cells undergo uncontrolled proliferation generating excessive numbers of undifferentiated cells; the egg chambers of differentiated (DIF) mutants differentiate to variable degrees but fail to complete oogenesis. We have examined mutations caused by insertion and deletion of P elements at the otu gene. The P element insertion sites are upstream of the major otu transcription start sites. In deletion derivatives, the P element, regulatory regions and/or protein coding sequences have been removed. In both insertion and deletion mutants, the level of otu expression correlates directly with the severity of the phenotype: the absence of otu function produces the most severe QUI phenotype while the ONC mutants express lower levels of otu than those which are DIF. The results of this study demonstrate that the diverse mutant phenotypes of otu are the consequence of different levels of otu function. PMID:8436274

Ovary and fimbrial stem cells: biology, niche and cancer origins.

PubMed

The mammalian ovary is covered by a single-layered epithelium that undergoes rupture and remodelling following each ovulation. Although resident stem cells are presumed to be crucial for this cyclic regeneration, their identity and mode of action have been elusive. Surrogate stemness assays and in vivo fate-mapping studies using recently discovered stem cell markers have identified stem cell pools in the ovary and fimbria that ensure epithelial homeostasis. Recent findings provide insights into intrinsic mechanisms and local extrinsic cues that govern the function of ovarian and fimbrial stem cells. These discoveries have advanced our understanding of stem cell biology in the ovary and fimbria, and lay the foundations for evaluating the contribution of resident stem cells to the initiation and progression of human epithelial ovarian cancer.

There has been controversy regarding the histogenesis of Brenner tumors. It is generally accepted that Brenner tumors are derived directly from ovarian surface epithelium, which undergoes metaplasia to form the typical urothelial-like components, whereas some investigators assume that Brenner tumors arise from immature germ cells. We describe a well-documented case of the coexistence of struma ovarii regarded as a form of teratoma and Brenner tumor in the same ovary. Immunohistologically, not only columnar cells of thyroid follicles, but also transitional cells of Brenner nests were positive for thyroglobulin. In the present case, Brenner tumors and thyroid elements coexisted and were positive for thyroglobulin. While there is strong evidence that pure Brenner tumors originate mostly from the ovarian surface, at least Brenner tumors associated with teratomatous elements may have a germ cell origin.

Dietary intake of lycopene has been associated with a reduced risk of ovarian cancer, suggesting its chemopreventive potential against ovarian carcinogenesis. Lycopene's molecular mechanisms of action in ovarian cancer have not been fully understood. Therefore, in the present study, we investigated the effects of lycopene on the ovarian cancer formation using the laying hen model, a biologically relevant animal model of spontaneous ovarian carcinogenesis due to high incidence rates similar to humans. In this study, a total of 150 laying hens at age of 102 weeks were randomized into groups of 50: a control group (0 mg of lycopene per kg of diet) and two treatment groups (200 mg or 400 mg of lycopene per kg of diet, or ~26 and 52 mg/d/hen, respectively). At the end of 12 months, blood, ovarian tissues and tumors were collected. We observed that lycopene supplementation significantly reduced the overall ovarian tumor incidence ( P < 0.01) as well as the number and the size of the tumors ( P < 0.004 and P < 0.005, respectively). Lycopene also significantly decreased the rate of adenocarcinoma, including serous and mucinous subtypes ( P < 0.006). Moreover, we also found that the serum level of oxidative stress marker malondialdehyde was significantly lower in lycopene-fed hens compared to control birds ( P < 0.001). Molecular analysis of the ovarian tumors revealed that lycopene reduced the expression of NF-κB while increasing the expression of nuclear factor erythroid 2 and its major target protein, heme oxygenase 1. In addition, lycopene supplementation decreased the expression of STAT3 by inducing the protein inhibitor of activated STAT3 expression in the ovarian tissues. Taken together, our findings strongly support the potential of lycopene in the chemoprevention of ovarian cancer through antioxidant and anti-inflammatory mechanisms.

To evaluate the effect of uterine artery embolization (UAE) and hysterectomy on ovarian function. Prospective case control study (Canadian Task Force classification II-2). University teaching hospital. Eighty-four healthy premenopausal women with symptomatic uterine myoma(s) undergoing UAE or hysterectomy. Patients had blood drawn to measure follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels and underwent transvaginal ultrasound to measure volume of the myoma(s) and uterus on cycle day 3 before the procedures. These measurements were repeated 3 and 6 months after treatment. The main outcome was the differences in serum FSH, LH, E2, and ultrasound findings before and after UAE or hysterectomy. Of the 68 patients who underwent UAE and 16 who underwent hysterectomy, 48 and 13 respectively, completed 6-month follow-up. The mean age of the patients in the UAE group was 44.9 +/- 3.8 years and 43.7 +/- 5.6 years in the hysterectomy group. There was no significant difference in serum FSH before (8.9 +/- 0.7 IU/L) and 6 months after UAE (9.9 +/- 1.0 lU/L), and between the baseline (10.4 +/- 1.8 lU/L) and 6 months posthysterectomy (7.8 +/- 1.8 lU/L). The uterine volume 6 months after UAE (361 +/- 50 mL) was significantly smaller than before UAE(538 +/- 38mL; p =.005, 95% CI 44-241). Compared with baseline (154 +/- 20 mL), the dominant myoma volume was smaller at 6 months after UAE (97 +/- 16 mL; p <.05, 95% CI 1.57-62). Uterine artery embolization is associated with a significant reduction in myoma and uterine volume. Ovarian function at 6 months, as indicated by day 3 FSH levels, is not affected by UAE or hysterectomy.

Previous studies of anthropometric factors and ovarian cancer risk have been inconsistent and none have evaluated the association among African-American women. Data from a population-based, case-control study of 593 cases and 628 controls were used to evaluate ovarian cancer risk in relation to weight, height, body mass index (BMI) and waist-to-hip ratio (WHR). Odds ratios (ORs) and 95% confidence intervals (CIs) were computed and established risk factors were adjusted for using logistic regression models, stratified by race. Among all races, weight at age 18, WHR, weight and BMI one year prior to interview were associated with elevated ovarian cancer risk. When stratified by race, the association between WHR and ovarian was similar among Whites and among African Americans. However, African-American women in the fourth quartile of height had an elevated risk of ovarian cancer (OR = 3.2; 95% CI = 1.3-7.8), but this risk was not apparent in Whites (OR = 1.0; 95% CI = 0.7-1.4). These findings support the hypothesis that obesity is an important risk factor of ovarian cancer among African-Americans and Whites and also suggest that height may be a risk factor specific to African-Americans.

What is the effect of different alkylating agents used without pelvic radiation to treat childhood cancer in girls on the ovarian reserve in survivors? Ovarian reserve seems to be particularly reduced in survivors who received procarbazine (in most cases for Hodgkin lymphoma) or high-dose chemotherapy; procarbazine but not cyclophosphamide dose is associated with diminished ovarian reserve. A few studies have demonstrated diminished ovarian reserve in survivors after various combination therapies, but the individual role of each treatment is difficult to assess. Prospective cross-sectional study, involving 105 survivors and 20 controls. One hundred and five survivors aged 17-40 years and 20 controls investigated on Days 2-5 of a menstrual cycle or Day 7 of an oral contraceptive pill-free interval. ovarian surface area (OS), total number of antral follicles (AFC), serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol and anti-Müllerian hormone (AMH). Survivors had a lower OS than controls: 3.5 versus 4.4 cm(2) per ovary (P = 0.0004), and lower AMH levels: 10.7 versus 22 pmol/l (P = 0.003). Ovarian markers (OS, AMH, AFC) were worse in patients who received high-dose compared with conventional-dose alkylating agents (P = 0.01 for OS, P = 0.002 for AMH, P < 0.0001 for AFC). Hodgkin lymphoma survivors seemed to have a greater reduction in ovarian reserve than survivors of leukaemia (P = 0.04 for AMH, P = 0.01 for AFC), sarcoma (P = 0.04 for AMH, P = 0.04 for AFC) and other lymphomas (P = 0.04 for AFC). A multiple linear regression analysis showed that procarbazine but not cyclophosphamide nor ifosfamide dose was associated with reduced OS (P = 0.0003), AFC (P = 0.0007), AMH (P < 0.0001) and higher FSH levels (P < 0.0001). The small percentage of participating survivors (28%) from the total cohort does not allow conclusion on fertility issues because of possible response bias. The association between procarbazine and HL makes it impossible to dissociate their individual impacts on ovarian reserve. The number of controls is small, but ovarian volume and AMH levels in survivors were compared with published normal values and results were unchanged. Early detection and follow-up of compromised ovarian function after cancer therapy should help physicians to counsel young survivors about their fertility window. However, longitudinal follow-up is required to determine the rate of progression from low ovarian reserve to premature ovarian failure. La Ligue contre le Cancer (grant no., PRAYN7497).

There is a mounting body of evidence demonstrating higher percentages of regulatory T (Treg) cells in the peripheral blood of patients with cancer in comparison to healthy controls, but there is a paucity of epidemiological literature characterizing circulating Treg cells among patients with epithelial ovarian cancer (EOC). To investigate the role of peripheral Treg cells in ovarian neoplasms, we conducted a case-control study to characterize circulating concentrations of Treg cells among patients with EOC, women with benign ovarian conditions, and healthy controls without a history of cancer. Participants were identified for inclusion due to their participation in the Data Bank and BioRepository program at Roswell Park Cancer Institute in Buffalo, NY. Patients included 71 women with a primary diagnosis of EOC and 195 women with a diagnosis of benign ovarian conditions. Controls included 101 age- and race-matched women without a history of cancer. Nonfasting, pretreatment peripheral blood levels of CD3+CD4+CD25+FOXP3+ Treg cells were measured using flow cytometric analyses and expressed as a percentage of total CD3+ cells and as a percentage of total CD3+CD4+ cells. Compared to healthy controls and women with benign ovarian conditions, patients with EOC had significantly higher frequency of Treg cells (P < 0.04). In multivariable logistic regression analyses using Treg frequency expressed as a percentage of CD+3 cells, we observed a significant positive association between Treg cell percentage and EOC risk, with each 1% increase associated with a 37% increased risk of EOC (odds ratio, 1.37; 95% confidence interval, 1.04-1.80). We observed a similar trend when Treg frequency was expressed as a percentage of CD3+CD+4 cells (odds ratio, 1.22; 95% confidence interval, 0.99-1.49). The current study provides support that peripheral Treg cell frequency is elevated in patients with EOC in comparison to women with benign ovarian conditions and healthy controls.

Sister chromatid exchange (SCE) frequencies were studied in patients with different types of ovarian malignancies and in healthy volunteers. The level of DNA damage in patients with ovarian malignancy and control subjects has also been studied by alkaline single cell gel electrophoresis (SCGE), also known as the comet assay. Peripheral blood was collected from 30 patients after histological confirmation of malignancy and 20 healthy female volunteers. The cells were evaluated according to their grade of damage. We found that the sister chromatid exchange frequencies of cancer cases were significantly greater than that of controls (P < 0.001). The frequency of exchange in chromosomal groups A, B, and C, which include chromosomes 1-12, was higher than that of the other chromosomal groups in both groups. Comparison of the results of the alkaline comet assay in patient and control subjects showed a significant difference in the number of damaged cells. The frequency of limited migrated and extensive migrated cells in the women with ovarian malignancies was higher than that of control women (P < 0.001). SCE and SCGE can be used successfully to monitor DNA damage in women with ovarian cancer.

Are neurokinin B (NKB), NK3 receptor (NK3R), kisspeptin (KISS1) and kisspeptin receptor (KISS1R) expressed in human ovarian granulosa cells? The NKB/NK3R and kisspeptin/KISS1R systems are co-expressed and functionally active in ovarian granulosa cells. The NKB/NK3R and KISS1/KISS1R systems are essential for reproduction. In addition to their well-recognized role in hypothalamic neurons, these peptide systems may contribute to the control of fertility by acting directly on the gonads, but such a direct gonadal role remains largely unknown. This study analyzed matched mural granulosa cells (MGCs) and cumulus cells (CCs) collected from preovulatory follicles of oocyte donors at the time of oocyte retrieval. The samples were provided by 56 oocyte donor women undergoing ovarian stimulation treatment. Follicular fluid samples containing MGCs and cumulus-oocyte complexes were collected after transvaginal ultrasound-guided oocyte retrieval. RT-PCR, quantitative real-time PCR, immunocytochemistry and western blot were used to investigate the pattern of expression of the NKB/NK3R and KISS/KISS1R systems in MGCs and CCs. Intracellular free Ca(2+) levels, [Ca(2+)]i, in MGCs after exposure to NKB or KISS1, in the presence or not of tachykinin receptor antagonists, were also measured. NKB/NK3R and KISS1/KISS1R systems were expressed, at the mRNA and protein levels, in MGCs and CCs, with significantly higher expression in CCs. Kisspeptin increased the [Ca(2+)]i in the cytosol of human MGCs while exposure to NKB failed to induce any change in [Ca(2+)]i. However, the [Ca(2+)]i response to kisspeptin was reduced in the presence of NKB. The inhibitory effect of NKB was only partially mimicked by the NK3R agonist, senktide and marginally suppressed by the NK3R-selective antagonist SB 222200. Yet, a cocktail of antagonists selective for the NK1, NK2 and NK3 receptors blocked the effect of NKB. The granulosa and cumulus cells were obtained from oocyte donors undergoing ovarian stimulation, which in comparison with natural cycles, may have affected gene and protein expression in granulosa cells. Our data demonstrate that, in addition to their indispensable effects at the central nervous system, the NKB/NK3R and kisspeptin/KISS1R systems are co-expressed and are functionally active in non-neuronal reproductive cells of the female gonads, the ovarian granulosa cells.

Cystic fibrosis (CF) is one of the most common genetic disorders that can often lead to chronic pulmonary disease. Patients with respiratory failure due to CF may achieve a good quality of life after lung transplant, and many will desire to have children. A 26-year-old, nulliparous female with CF and double lung transplant presented for fertility treatment. She was successfully treated with controlled ovarian hyperstimulation and gestational surrogacy. Controlled ovarian hyperstimulation and gestational surrogacy is a safe option for patients with lung transplant to have a genetic child.

It has been recently suggested that gonadotrophin-releasing hormone agonist down-regulation in some normogonadotrophic women may result in profound suppression of LH concentrations, impairing adequate oestradiol synthesis and IVF and pregnancy outcome. The aims of this study, where receiver-operating characteristic (ROC) analysis was used, were: (i) to assess the usefulness of serum LH measurement on stimulation day 7 (S7) as a predictor of ovarian response, IVF outcome, implantation, and the outcome of pregnancy in patients treated with recombinant FSH under pituitary suppression; and (ii) to define the best threshold value, if any, to discriminate between women with 'low' or 'normal' LH concentrations. A total of 144 infertile women undergoing IVF/intracytoplasmic sperm injection (ICSI) treatment were included. Seventy-two consecutive patients having a positive pregnancy test (including 58 ongoing pregnancies and 14 early pregnancy losses) were initially selected. As a control non-pregnant group, the next non-conception IVF/ICSI cycle after each conceptual cycle in our assisted reproduction programme was used. The median and range of LH values in non-conception cycles, conception cycles, ongoing pregnancies, and early pregnancy losses, clearly overlapped. ROC analysis showed that serum LH concentration on S7 was unable to discriminate between conception and non-conception cycles (AUC(ROC) = 0.52; 95% CI: 0.44 to 0.61) or ongoing pregnancy versus early pregnancy loss groups (AUC(ROC) = 0.59; 95% CI: 0.46 to 0.70). To assess further the potential impact of suppressed concentrations of circulating LH during ovarian stimulation on the outcome of IVF/ICSI treatment, the three threshold values of mid-follicular serum LH proposed in the literature (<1, < or =0.7, <0.5 IU/l) to discriminate between women with 'low' or 'normal' LH were applied to our study population. No significant differences were found with respect to ovarian response, IVF/ICSI outcome, implantation, and the outcome of pregnancy between 'low' and 'normal' S7 LH women as defined by those threshold values. Our results do not support the need for additional exogenous LH supplementation in down-regulated women receiving a recombinant FSH-only preparation.

Drugs with potential chemopreventive properties in relation to epithelial ovarian cancer--a nationwide case-control study.

PubMed

Baandrup, Louise

2015-07-01

Ovarian cancer has a poor prognosis because the disease in the majority of patients is diagnosed at an advanced stage as a result of nonspecific symptoms and lack of efficient screening methods. Because of the poor prognosis of ovarian cancer and the challenge of early detection of the disease, identification of protective factors is important. It has been suggested that some commonly used drugs may have a protective effect against cancer, including ovarian cancer; however, the literature on chemopreventive measures for ovarian cancer is sparse and the results are inconclusive. Most previous studies have substantial methodological constraints, including limited study size and self-reporting of drug use, which introduces potential recall bias and misclassification. This PhD thesis includes a nationwide case-control study to evaluate associations between use of drugs with potential chemopreventive properties and risk of epithelial ovarian cancer. The study is nested in the entire Danish female population using data from the following nationwide registries: the Danish Cancer Registry, the Danish Civil Registration System, the Danish Prescription Registry, the Danish National Patient Register, and registries in Statistics Denmark on fertility, education, and income. Information from the included registries is linked by use of the unique personal identification number assigned to all Danish citizens. The cases were all women in Denmark with epithelial ovarian cancer diagnosed during 2000-2009 (Paper 1) and 2000-2011 (Papers 2 and 3), identified in the Cancer Registry. Age-matched female population controls were randomly selected from the Civil Registration System by risk-set sampling. We required that cases and controls have no history of cancer (except non-melanoma skin cancer) and that controls not previously have undergone bilateral oophorectomy or salpingo-oophorectomy. The total study population comprised 3741 epithelial ovarian cancer cases and 50,576 controls in Paper 1, and 4103 epithelial ovarian cancer cases and 58,706 controls in Papers 2 and 3. We used the Danish Prescription Registry to assess use (≥2 prescriptions on separate dates) of paracetamol, non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs), low-dose aspirin, and statins. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for epithelial ovarian cancer associated with use of the study drugs, with adjustment for potential confounding factors selected a priori. We performed detailed analyses according to duration, intensity, and continuity of study drug use, and the analyses were stratified according to specific histologic types of epithelial ovarian cancer. In all studies, non-use (< 2 prescriptions) of the individual study drugs was defined as the reference group. A striking result of the PhD thesis was a strong inverse association between prescription use of paracetamol and risk of epithelial ovarian cancer. The risk estimates decreased with increasing duration and intensity of paracetamol use, reaching a more than 50% reduction for the longest duration (>10 years) and the highest doses (OR: 0.45; 95% CI: 0.24-0.86). In contrast, we did not observe an inverse association between use of non-aspirin NSAIDs and risk of epithelial ovarian cancer. Moreover, this thesis provides further evidence that use of low-dose aspirin is associated with a reduced risk of epithelial ovarian cancer. In particular, long-term (≥5 years) continuous use of low-dose aspirin, defined as overlapping prescription coverage periods, was associated with a large reduction in risk (OR: 0.56; 95% CI: 0.32-0.97). Finally, we found no apparent association between statin use and epithelial ovarian cancer risk, although the analysis by histologic type suggested an inverse association with the risk of mucinous tumors. The results of this PhD thesis add important knowledge to the area of chemoprevention in relation to epithelial ovarian cancer. As for any observational study, we cannot exclude potential con-founding and exposure misclassification; however, methodological limitations appear unlikely to fully explain the observed reductions in epithelial ovarian cancer risk associated with paracetamol and low-dose aspirin use. Additional research, ideally from clinical trials, is needed before our observations may lead to recommendations for chemopreventive measures against ovarian cancer. In case consensus points to a true protective effect of paracetamol or low-dose aspirin, comprehensive risk-benefit evaluations will also have to be performed. We hope that our results will encourage researchers to look more deeply into the potential chemo-preventive effects of the study drugs against epithelial ovarian cancer risk.

The role of ovarian surgery in polycystic ovary syndrome.

PubMed

Problems in inducing ovulation in women with polycystic ovary syndrome (PCOS) and anovulation are well recognized. In 1935, Stein and Leventhal first described surgical treatment by ovarian wedge resection at laparotomy for women with anovulation and PCOS. Ovarian wedge resection was eventually abandoned because of the significant risk of postsurgical adhesion formation, which resulted in tubal adhesions, and because of the advent of medical ovulation induction with clomiphene and gonadotrophins. However, since the arrival of minimally invasive surgical techniques, laparoscopic ovarian surgery has become feasible. The potential advantages of laparoscopic ovarian surgery include repeated single ovulations and less adhesion formation. Lowered costs make ovarian surgery an attractive alternative to gonadotrophins. However, although many case series have suggested that ovarian surgery is an effective strategy, few randomized, controlled trials have been undertaken comparing the success rates of surgery with gonadotrophins. The long-term concerns with surgery include adhesion formation and premature ovarian failure.

To evaluate whether endometriosis-associated genetic variation affects risk of ovarian cancer. Pooled genetic analysis. University hospital. Genetic data from 46,176 participants (15,361 ovarian cancer cases and 30,815 controls) from 41 ovarian cancer studies. None. Endometriosis-associated genetic variation and ovarian cancer. There was significant evidence of an association between endometriosis-related genetic variation and ovarian cancer risk, especially for the high-grade serous and clear cell histotypes. Overall we observed 15 significant burden statistics, which was three times more than expected. By focusing on candidate regions from a phenotype associated with ovarian cancer, we have shown a clear genetic link between endometriosis and ovarian cancer that warrants further follow-up. The functional significance of the identified regions and SNPs is presently uncertain, though future fine mapping and histotype-specific functional analyses may shed light on the etiologies of both gynecologic conditions.

BACKGROUND Women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) are given letrozole before a trigger injection of human chorionic gonadotropin (hCG) to lower estrogen (E2) levels, but can experience ovarian hyperstimulation syndrome (OHSS). The aim of this study was to evaluate the effect of oral letrozole, prior to administration of hCG, on the outcome of IVF and development of OHSS. MATERIAL AND METHODS Retrospective clinical review included 181 cases of women with PCOS who underwent IVF cycles with intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) (IVF/ICSI-ET). The day before the use of hCG, cases were divided into a letrozole-treated group (N=78) and a non-letrozole group (N=103). An oral dose of 2.5 mg qd of letrozole was given when the peak level of E2 was ≥4000 pg/ml during ovarian stimulation and ceased before the day of egg retrieval. RESULTS The letrozole-treated group had a significant increase in the number of retrieved oocytes, viable embryos, and fresh ET rate (P>0.05); peak levels of E2, and E2 levels on the day of the egg retrieval, were significantly higher, and the fertilization rate was significantly lower (P<0.001). No significant differences were found in the rates of pregnancy, abortion, or ectopic pregnancy between the two groups (P>0.05). The incidence OHSS was lower in the letrozole-treated group, but this difference did not reach statistical significance (P>0.05). CONCLUSIONS Women with PCOS who underwent IVF, oral treatment with letrozole a day prior to treatment with hCG lowered E2 levels, but did not significantly reduce the incidence of OHSS.

To study implications of psychological distress on in vitro fertilization (IVF) outcome of an infertile couple. Prospective study in an academic infertility practice setting. Couples undergoing embryo transfer (ET) following IVF were offered participation. Female patient (n = 89) and partner (n = 77) completed questionnaires reflecting dysphoria (POMS) and pessimism (LOT) after undergoing ET. Relationship between dysphoria and pessimism and implications of individual and couple's psychological distress on IVF cycle parameters and outcomes were assessed using multivariable analyses. Statistically significant correlations between dysphoria and pessimism were observed within the individual and between partners, (p < 0.01). Higher couple pessimism correlated with longer duration of controlled ovarian hyperstimulation (COH, p = 0.02); higher partner psychological distress related to lower fertilization rate (FR, p = 0.03). On adjusted analyses, partner's depression score was an independent predictor of reduced likelihood of clinical pregnancy (p = 0.03). Our data validate the concept of a "stressed couple". Adverse implications of a couple's psychological distress for gamete biology (longer duration of COH and lower FR with increasing distress) are suggested. Partner's depressive scores negatively correlated with IVF success. These findings suggest the importance of including partner's evaluation in studies that focus on effects of psychological stress on IVF outcome; future studies should examine whether interventions aimed at reducing psychological stress for the infertile couple may improve IVF cycle success.

The aim of this study is to estimate the percentage of patients with metastatic ovarian, fallopian tube, and primary peritoneal cancer requiring ultra-radical surgery to achieve cytoreduction to less than 1 cm (optimal) or no macroscopic residual disease (complete). Perioperative data were collected prospectively on consecutive patients undergoing elective cytoreductive surgery for metastatic epithelial ovarian, fallopian tube, or primary peritoneal cancer at the Norfolk and Norwich University Hospital, a tertiary referral cancer centre in the United Kingdom from November 2012 to June 2016. Over a 42-month period, 135 consecutive patients underwent cytoreductive surgery for stage IIIC and IV ovarian, fallopian tube, or primary peritoneal cancer. The median age of the patients was 69 years. 47.4% of the patients underwent diaphragmatic peritonectomy and/or resection, 20% underwent splenectomy, 14.1% had excision of disease from porta hepatis and celiac axis, and 5.2% of the patients had gastrectomy. Cytoreduction to no macroscopic visible disease (complete) and to disease with greater tumour diameter of less than 1 cm (optimal) was achieved in 54.1 and 34.1% of the cases, respectively. Without incorporating surgical procedures in the upper abdomen ('ultra-radical'), the combined rate of complete and optimal cytoreduction would be only 33.3%. Up to 50.4% of the patients in this study required at least one surgical procedure classified as ultra-radical, emphasizing the importance of cytoreductive surgery in the upper abdomen in management of women with stage IIIC and IV ovarian, fallopian tube, and primary peritoneal cancer.

Safe and targeted anticancer therapy for ovarian cancer using a novel class of curcumin analogs

PubMed Central

2013-01-01

A diagnosis of advanced ovarian cancer is the beginning of a long and arduous journey for a patient. Worldwide, approximately half of the individuals undergoing therapy for advanced cancer will succumb to the disease, or consequences of treatment. Well-known and widely-used chemotherapeutic agents such as cisplatin, paclitaxel, 5-fluorouracil, and doxorubicin are toxic to both cancer and non-cancerous cells, and have debilitating side effects Therefore, development of new targeted anticancer therapies that can selectively kill cancer cells while sparing the surrounding healthy tissues is essential to develop more effective therapies. We have developed a new class of synthetic curcumin analogs, diarylidenyl-piperidones (DAPs), which have higher anticancer activity and enhanced bio-absorption than curcumin. The DAP backbone structure exhibits cytotoxic (anticancer) activity, whereas the N-hydroxypyrroline (-NOH) moiety found on some variants functions as a cellular- or tissue-specific modulator (antioxidant) of cytotoxicity. The anticancer activity of the DAPs has been evaluated using a number of ovarian cancer cell lines, and the safety has been evaluated in a number of non-cancerous cell lines. Both variations of the DAP compounds showed similar levels of cell death in ovarian cancer cells, however the compounds with the -NOH modification were less toxic to non-cancerous cells. The selective cytotoxicity of the DAP–NOH compounds suggests that they will be useful as safe and effective anticancer agents. This article reviews some of the key findings of our work with the DAP compounds, and compares this to some of the targeted therapies currently used in ovarian cancer therapy. PMID:23663277

Good-quality oocytes are critical for the success of in vitro fertilization (IVF), but, to date, there is no marker of ovarian reserve available that can accurately predict oocyte quality. Melatonin exerts its antioxidant actions as a strong radical scavenger that might affect oocyte quality directly as it is the most potent antioxidant in follicular fluid. To investigate the precise role of endogenous melatonin in IVF outcomes, we recruited 61 women undergoing treatment cycles of IVF or intracytoplasmic sperm injection (ICSI) procedures and classified them into three groups according to their response to ovarian stimulation. Follicular fluid was collected to assess melatonin levels using a direct RIA method. We found good correlations between melatonin levels in follicular fluid with age, anti-Müllerian hormone (AMH) and baseline follicle-stimulating hormone (bFSH), all of which have been used to predict ovarian reserve. Furthermore, as melatonin levels correlated to IVF outcomes, higher numbers of oocytes were collected from patients with higher melatonin levels and consequently the number of oocytes fertilized, zygotes cleaved, top quality embryos on D3, blastocysts obtained and embryos suitable for transplantation was higher. The blastocyst rate increased in concert with the melatonin levels across the gradient between the poor response group and the high response group. These results demonstrated that the melatonin levels in follicular fluid is associated with both the quantity and quality of oocytes and can predict IVF outcomes as well making them highly relevant biochemical markers of ovarian reserve. © 2017 Society for Reproduction and Fertility.

Objectives Ovarian cancer is the fourth leading cause of cancer-related death among women in the US largely due to late detection secondary to unreliable symptomology and screening tools without adequate resolution. Optical coherence tomography (OCT) is a recently emerging imaging modality with promise in ovarian cancer diagnostics, providing non-destructive subsurface imaging at imaging depths up to 2 mm with near-histological grade resolution (10–20 μm). In this study, we developed the first ever laparoscopic OCT (LOCT) device, evaluated the safety and feasibility of LOCT, and characterized the microstructural features of human ovaries in vivo. Methods A custom LOCT device was fabricated specifically for laparoscopic imaging of the ovaries in patients undergoing oophorectomy. OCT images were compared with histopathology to identify preliminary architectural imaging features of normal and pathologic ovarian tissue. Results Thirty ovaries in 17 primarily peri or post-menopausal women were successfully imaged with LOCT: 16 normal, 5 endometriosis, 3 serous cystadenoma, and 4 adenocarcinoma. Preliminary imaging features developed for each category reveal qualitative differences in the homogeneous character of normal post-menopausal ovary, the ability to image small subsurface inclusion cysts, and distinguishable features for endometriosis, cystadenoma, and adenocarcinoma. Conclusions We present the development and successful implementation of the first laparoscopic OCT probe. Comparison of OCT images and corresponding histopathology allowed for the description of preliminary microstructural features for normal ovary, endometriosis, and benign and malignant surface epithelial neoplasms. These results support the potential of OCT both as a diagnostic tool and imaging modality for further evaluation of ovarian cancer pathogenesis. PMID:19481241

Obesity and insulin resistance are associated with increased iron stores, but have conflicting effects on ovarian reserve in women with polycystic ovary syndrome (PCOS). Iron-catalyzed oxidative stress might be detrimental to ovarian tissue and granulosa cell function. In this study we determined the association between body iron stores, obesity, and ovarian reserve in women with PCOS. One hundred and fifty-six women diagnosed with PCOS according to Rotterdam criteria and 30 normoweight healthy control women were enrolled in this cross-sectional study. Ovarian volume, total antral follicle count, and the anti-Müllerian hormone (AMH) level were measured as an indicator of ovarian reserve. Ferritin and transferrin-bound iron levels were significantly higher in women with PCOS than normoweight controls. Obese women with PCOS had higher ferritin levels (p = 0.006), but lower AMH levels (p < 0.0001) than nonobese women with PCOS. Using univariate analysis, the AMH level and mean ovarian volume were inversely related to the ferritin level, homeostasis model assessment of insulin resistance, and body mass index in women with PCOS. Body mass index and ferritin level remained significantly correlated with a lower AMH level and reduced ovarian volume, respectively, after considering other confounding variables. An elevated ferritin level and obesity were negatively associated with ovarian volume and the AMH level, respectively, in women with PCOS. Copyright © 2015. Published by Elsevier B.V.

Objective To provide evidence about the performance characteristics and consequences of bimanual ovarian palpation. Setting and methods The Prostate, Lung, Colorectal and Ovarian cancer screening trial randomized 154,900 individuals to either an intervention or control arm. Enrolled eligible participants were aged 55-74, had no history of trial cancers, and no current treatment for cancer. Intervention arm women received CA-125 tests and transvaginal ultrasound. Bimanual ovarian palpation was offered annually during the first four years of the trial. Bimanual ovarian palpation-specific sensitivity and specificity were calculated, as were rates of diagnostic procedures and resulting complications following positive bimanual ovarian palpation screens. Results A total of 20,872 women received at least one bimanual ovarian palpation, with 50,498 total bimanual ovarian palpation examinations performed. The sensitivity and specificity of bimanual ovarian palpation were 5.1% (2/39) and 99.0% (49,957/50,459), respectively; no cases were detected by bimanual ovarian palpation alone. Rates for most follow-up procedures for abnormal results in women without ovarian cancer were higher among the group with another screening test positive, except for pelvic exam, where rates were similar. No complications were reported in the bimanual ovarian palpation-only positive group. Conclusion Low sensitivity of bimanual ovarian palpation alone and in combination with other tests argue against using bimanual ovarian palpation as a screening test for ovarian cancer in asymptomatic women.

Epithelial ovarian cancer has a major heritable component, but the known susceptibility genes explain less than half the excess familial risk1. We performed a genome wide association study (GWAS) to identify common ovarian cancer susceptibility alleles. We evaluated 507,094 SNPs genotyped in 1,817 cases and 2,353 controls from the UK and ~2 million imputed SNPs. We genotyped the 22,790 top ranked SNPs in 4,274 cases and 4,809 controls of European ancestry from Europe, USA and Australia. We identified 12 SNPs at 9p22 associated with disease risk (P<10−8). The most significant SNP (rs3814113; P = 2.5 × 10−17) was genotyped in a further 2,670 ovarian cancer cases and 4,668 controls confirming its association (combined data odds ratio = 0.82 95% CI 0.79 – 0.86, P-trend = 5.1 × 10−19). The association differs by histological subtype, being strongest for serous ovarian cancers (OR 0.77 95% CI 0.73 – 0.81, Ptrend = 4.1 × 10−21). PMID:19648919

New serological biomarkers for early detection and clinical management of ovarian cancer are urgently needed, and many candidates have been reported. A major challenge frequently encountered when validating candidates in patients is establishing quantitative assays that distinguish between highly homologous proteins. The current study tested whether multiple members of two recently discovered ovarian cancer biomarker protein families, chloride intracellular channel (CLIC) proteins and tropomyosins (TPM), were detectable in ovarian cancer patient sera. A multiplexed, label-free multiple reaction monitoring (MRM) assay was established to target peptides specific to all detected CLIC and TPM family members, and their serum levels were quantitated for ovarian cancer patients and non-cancer controls. In addition to CLIC1 and TPM1, which were the proteins initially discovered in a xenograft mouse model, CLIC4, TPM2, TPM3, and TPM4 were present in ovarian cancer patient sera at significantly elevated levels compared with controls. Some of the additional biomarkers identified in this homolog-centric verification and validation approach may be superior to the previously identified biomarkers at discriminating between ovarian cancer and non-cancer patients. This demonstrates the importance of considering all potential protein homologs and using quantitative assays for cancer biomarker validation with well-defined isoform specificity. This manuscript addresses the importance of distinguishing between protein homologs and isoforms when identifying and validating cancer biomarkers in plasma or serum. Specifically, it describes the use of targeted in-depth LC-MS/MS analysis to determine the members of two protein families, chloride intracellular channel (CLIC) and tropomyosin (TPM) proteins that are detectable in sera of ovarian cancer patients. It then establishes a multiplexed isoform- and homology-specific MRM assay to quantify all observed gene products in these two protein families as well as many of the closely related tropomyosin isoforms. Using this assay, levels of all detected CLICs and TPMs were quantified in ovarian cancer patient and control subject sera. These results demonstrate that in addition to the previously known CLIC1, multiple tropomyosins and CLIC4 are promising new ovarian cancer biomarkers. Based on these initial validation studies, these new ovarian cancer biomarkers appear to be superior to most previously known ovarian cancer biomarkers. Copyright © 2013 Elsevier B.V.

Isoflavones, mainly found in soy, have been shown to inhibit ovarian cancer cell proliferation. We hypothesized that soy consumption and isoflavone intake are related to the risk of ovarian cancer. A case-control study was conducted in southern China to ascertain this hypothesis. Five hundred incident patients with histologically confirmed cancer of the ovary and 500 controls (mean age 59 years) were recruited from four public hospitals in Guangzhou. Information on habitual consumption of soy foods, including soybean, soy milk, fresh tofu, dried tofu, and soybean sprout, was obtained face-to-face from participants through a validated and reliable semi-quantitative food frequency questionnaire. Isoflavone intakes were then estimated using the USDA nutrient database. The ovarian cancer patients reported lower consumption levels of individual and total soy foods (75.3 ± 53.6 g/day) compared to the controls (110.7 ± 88.8 g/day). Logistic regression analyses showed that regular intake of soy foods could reduce the ovarian cancer risk, the adjusted odds ratio being 0.29 (95% confidence interval 0.20 to 0.42) for women who consumed at least 120 g/day relative to those less than 61 g/day. Similarly, isoflavone intakes were inversely associated with the ovarian cancer risk, with significant dose-response relationships (P < 0.001). We concluded that consumption of soy foods is associated with a reduced risk of ovarian cancer in southern Chinese women. Copyright © 2014 Elsevier Inc. All rights reserved.

Guidelines recommend genetic counseling and testing for women who have a pedigree suggestive of an inherited susceptibility for ovarian cancer. The authors evaluated the effect of referral to genetic counseling on genetic testing and prophylactic oophorectomy in a randomized controlled trial. Data from an electronic mammography reporting system identified 12,919 women with a pedigree that included breast cancer, of whom 625 were identified who had a high risk for inherited susceptibility to ovarian cancer using a risk-assessment questionnaire. Of these, 458 women provided informed consent and were randomized 1:1 to intervention consisting of a genetic counseling referral (n = 228) or standard clinical care (n = 230). Participants were predominantly aged 45 to 65 years, and 30% and 20% reported a personal history of breast cancer or a family history of ovarian cancer, respectively. Eighty-five percent of women in the intervention group participated in a genetic counseling session. Genetic testing was reported by 74 (33%) and 20 (9%) women in the intervention and control arms (P < .005), respectively. Five women in the intervention arm and 2 in the control arm were identified as germline mutation carriers. Ten women in the intervention arm and 3 in the control arm underwent prophylactic bilateral salpingo-oophorectomy (P < .05). Routine referral of women at high risk for ovarian cancer to genetic counseling promotes genetic testing and prophylactic surgery. The findings from the current randomized controlled trial demonstrate the value of implementing strategies that target women at high risk for ovarian cancer to ensure they are offered access to recommended care.

Purpose Test the hypothesis that puerperal mastitis may alter immunity related to the mucin (MUC) family of glycoproteins and lower risk for ovarian cancer. Methods In two case-control studies conducted in New England between 1998–2008, we examined the association between self-reported mastitis and ovarian cancer in 1,483 women with epithelial ovarian cancer and 1,578 controls. IgG1 antibodies against (MUC1) CA15.3 and (MUC16) CA125 were measured using electrochemiluminescence assays in a subset of controls (n=200). Preoperative CA125 was recorded in 649 cases. The association between ovarian cancer and mastitis was assessed using unconditional logistic regression to calculate adjusted odds ratios, OR, and 95% confidence intervals (CI). Associations between mastitis and anti-CA15.3 and anti-CA125 antibodies and preoperative CA125 levels were evaluated using adjusted linear regression models. Results Prior mastitis was associated with a significantly lower risk for ovarian cancer: OR (and 95% CI) of 0.67 (0.48, 0.94) adjusted for parity, breastfeeding, and other potential confounders. The association was strongest with 2 or more episodes of mastitis; and risk declined progressively with increasing number of children and episodes of mastitis. Among controls, prior mastitis was associated with significantly higher anti-CA15.3 and anti-CA125 antibody levels and, among cases, with significantly lower preoperative CA125 levels. Conclusion Puerperal that mastitis may produce long-lasting anti-mucin antibodies that may lower the risk for ovarian cancer, plausibly through enhanced immune surveillance. Studying immune reactions related to MUC1 and MUC16 in the 10–20% of breastfeeding women who develop mastitis may suggest ways to duplicate its effects through vaccines based on both antigens.

Multiple studies have examined the role of anthropometric characteristics in ovarian cancer risk and survival; however, their results have been conflicting. We investigated the associations between weight change, height and height change and risk and outcome of ovarian cancer using data from a large population-based case-control study. Data from 699 ovarian cancer cases and 1,802 controls who participated in the HOPE study were included. We used unconditional logistic regression adjusted for age, race, number of pregnancies, use of oral contraceptives, and family history of breast or ovarian cancer to examine the associations between self-reported height and weight and height change with ovarian cancer risk. Cox proportional hazards regression models adjusted for age and stage were used to examine the association between the exposure variables and overall and progression-free survival among ovarian cancer cases. We observed an increased risk of ovarian cancer mortality and progression for gaining more than 20 pounds between ages 18-30, HR 1.36; 95% CI 1.05-1.76, and HR 1.31; 95% CI 1.04-1.66, respectively. Losing weight and gaining it back multiple times was inversely associated with both ovarian cancer risk, OR 0.78; 95% CI 0.63-0.97 for 1-4 times and OR 0.73; 95% CI 0.54-0.99 for 5-9 times, and mortality, HR 0.63; 95% CI 0.40-0.99 for 10-14 times. Finally, being taller during adolescence and adulthood was associated with increased risk of mortality. Taller stature and weight gain over lifetime were not related to ovarian cancer risk. Our results suggest that height and weight and their change over time may influence ovarian cancer risk and survival. These findings suggest that biological mechanisms underlying these associations may be hormone driven and may play an important role in relation to ovarian carcinogenesis and tumor progression.

Exposure to environmental hazards will destroy a number of ovarian primordial follicles, reduce ovarian reserve and subsequent reproductive ability. This study designed to evaluate ovarian parameters and ovarian blood flow of women living in the area of environmental crisis Shalkar city (Kazakhstan) compared to women living in Aktobe city (Kazakhstan). 220 women in their reproductive age studied and classified into two groups; study (Shalkar) group and control (Aktobe) group. Blood sample taken from studied women during follicular phase (day 3) for hormonal level evaluation including; follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH). Studied women evaluated using trans-vaginal ultrasound (TVS) to detect antral follicle count (AFC) during follicular scan and ovarian volume (OV), ovarian blood flow (OBF) using pulsatility index (PI) during follicular scan and luteal scan. Both ovaries AFC was significantly less in study (Shalkar) group compared to and control (Aktobe) group (p=0.0001). Mean ovarian volume was significantly less in Shalkar group in both follicular phase and luteal phase (5.86±0.23 and 6.19±0.22Cm(3); respectively) compared to Aktobe group (6.85±0.19 and 6.92±0.18Cm(3); respectively). In addition, mean ovarian pulsatility index was significantly high with subsequent decrease in ovarian blood flow in Shalkar group in both follicular phase and luteal phase (3.36±0.20 and 3.45±0.19Cm/s; respectively) compared to Aktobe group (2.96±0.16 and 2.92±0.15Cm/s; respectively). This study suggests definite environmental effect on ovarian parameters as indicated by decreased AFC, decreased both follicular and luteal OV and OBF in women living in environmental crisis Shalkar group compared to Aktobe group.

The aim of this multicenter trial was to evaluate the role of ovarian suppression in patients with early breast cancer previously treated with local surgery and adjuvant chemotherapy. Nine hundred and twenty-six premenopausal patients with completely resected breast cancer and either axillary node involvement or histological grade 2 or 3 tumors were randomized after surgery to adjuvant chemotherapy alone (control arm) or adjuvant chemotherapy plus ovarian suppression (ovarian suppression arm). Ovarian suppression was obtained by either radiation-induced ovarian ablation or triptorelin for 3 years. The analyses were performed with Cox models stratified by center. Median follow-up was 9.5 years. Mean age was 43 years. Ninety per cent of patients had histologically proven positive axillary nodes, 63% positive hormonal receptors and 77% had received an anthracycline-based chemotherapy regimen. Ovarian suppression was by radiation-induced ovarian ablation (45% of patients) or with triptorelin (48%). At the time of randomization, all patients had regular menses or their follicle-stimulating hormone and estradiol levels indicated a premenopausal status. The 10-year disease-free survival rates were 49% [95% confidence interval (CI) 44% to 54%] in both arms (P = 0.51). The 10-year overall survival rates were 66% (95% CI 61% to 70%) for the ovarian suppression arm and 68% (95% CI 63% to 73%) for the control arm (P = 0.19). There were no variations in the treatment effect according to age, hormonal receptor status or ovarian suppression modality. However, in patients <40 years of age and with estrogen receptor-positive tumors, ovarian suppression significantly decreased the risk of recurrence (P = 0.01). The results of this trial, after at least 10 years of follow-up, do not favor the use of ovarian suppression after adjuvant chemotherapy. The potential beneficial effect in younger women with hormono-dependent tumors should be further assessed.

The metabolism of polyunsaturated fatty acids (PUFAs) remains poorly characterized in ovarian tissues of patients with polycystic ovary syndrome (PCOS). This study aimed to explore alterations in the levels of PUFAs and their metabolites in serum and ovarian tissues in a PCOS rat model treated with a high-fat diet and andronate. Levels of PUFAs and their metabolites were measured using gas/liquid chromatography-mass spectrometry after the establishment of a PCOS rat model. Only 3 kinds of PUFAs [linoleic acid, arachidonic acid (AA) and docosahexaenoic acid] were detected in both the circulation and ovarian tissues of the rats, and their concentrations were lower in ovarian tissues than in serum. Moreover, significant differences in the ovarian levels of AA were observed between control, high-fat diet-fed and PCOS rats. The levels of prostaglandins, AA metabolites via the cyclooxygenase (COX) pathway, in ovarian tissues of the PCOS group were significantly increased compared to those in the controls. Further studies on the mechanism underlying this phenomenon showed a correlation between decreased expression of phosphorylated cytosolic phospholipase A2 (p-cPLA2) and increased mRNA and protein expression of COX2, potentially leading to a deeper understanding of altered AA and prostaglandin levels in ovarian tissues of PCOS rats. © 2018 The Authors.

Reproductive characteristics, the most established ovarian cancer risk factors, differ markedly between African-American and white women. Studies in predominantly white populations suggest that associations between reproductive characteristics and ovarian cancer vary by timing of the events and menopause status. This analysis examined associations between number, duration, and timing of reproductive events and epithelial ovarian cancer among African-American women. Data from a multicenter case-control study of ovarian cancer in African-American women (641 cases/752 controls) were used to examine associations with oral contraceptive (OC) use and pregnancy characteristics. Odds ratios (ORs) and 95% confidence intervals (CIs) associated with reproductive characteristics were calculated with logistic regression models. OC use (OR = 0.7, 95% CI 0.5-0.9), parity (OR = 0.5, 95% CI 0.3-0.6), and breastfeeding for >12 months (OR = 0.3, 95% CI 0.2-0.5) were inversely associated with ovarian cancer. More recent pregnancies and OC use had stronger associations with ovarian cancer than pregnancies or OC use that occurred earlier in life, especially among premenopausal women. This study provides the first thorough documentation that pregnancy, breastfeeding, and OC use are inversely associated with ovarian cancer in African-American women, similar to what has been observed in white women. The associations with timing of the exposures suggest that these factors have both short- and long-term effects. Copyright © 2016 Elsevier Inc. All rights reserved.

Long and irregular menstrual cycles, a hallmark of polycystic ovary syndrome (PCOS), have been associated with higher androgen and lower sex hormone binding globulin levels and this altered hormonal environment may increase the risk of specific histologic subtypes of ovarian cancer. We investigated whether menstrual cycle characteristics and self-reported PCOS were associated with ovarian cancer risk among 2,041 women with epithelial ovarian cancer and 2,100 controls in the New England Case-Control Study (1992-2008). Menstrual cycle irregularity, menstrual cycle length, and PCOS were collected through in-person interview. Unconditional logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (95% CIs) for ovarian cancer risk overall, and polytomous logistic regression to evaluate whether risk differed between histologic subtypes. Overall, we observed no elevation in ovarian cancer risk for women who reported periods that were never regular or for those reporting a menstrual cycle length of >35 days with ORs of 0.87 (95% CI = 0.69-1.10) and 0.83 (95% CI = 0.44-1.54), respectively. We observed no overall association between self-reported PCOS and ovarian cancer (OR = 0.97; 95% CI = 0.61-1.56). However, we observed significant differences in the association with menstrual cycle irregularity and risk of ovarian cancer subtypes (p heterogeneity  = 0.03) as well as by BMI and OC use (p interaction  < 0.01). Most notable, menstrual cycle irregularity was associated with a decreased risk of high grade serous tumors but an increased risk of serous borderline tumors among women who had never used OCs and those who were overweight. Future research in a large collaborative consortium may help clarify these associations. © 2016 UICC.

Whilst previous studies have reported that higher BMI increases a woman's risk of developing ovarian cancer, associations for the different histological subtypes have not been well defined. As the prevalence of obesity has increased dramatically, and classification of ovarian histology has improved in the last decade, we sought to examine the association in a pooled analysis of recent studies participating in the Ovarian Cancer Association Consortium. We evaluated the association between BMI (recent, maximum and in young adulthood) and ovarian cancer risk using original data from 15 case-control studies (13 548 cases and 17 913 controls). We combined study-specific adjusted odds ratios (ORs) using a random-effects model. We further examined the associations by histological subtype, menopausal status and post-menopausal hormone use. High BMI (all time-points) was associated with increased risk. This was most pronounced for borderline serous (recent BMI: pooled OR=1.24 per 5 kg/m(2); 95% CI 1.18-1.30), invasive endometrioid (1.17; 1.11-1.23) and invasive mucinous (1.19; 1.06-1.32) tumours. There was no association with serous invasive cancer overall (0.98; 0.94-1.02), but increased risks for low-grade serous invasive tumours (1.13, 1.03-1.25) and in pre-menopausal women (1.11; 1.04-1.18). Among post-menopausal women, the associations did not differ between hormone replacement therapy users and non-users. Whilst obesity appears to increase risk of the less common histological subtypes of ovarian cancer, it does not increase risk of high-grade invasive serous cancers, and reducing BMI is therefore unlikely to prevent the majority of ovarian cancer deaths. Other modifiable factors must be identified to control this disease.

STK15 is a putative oncogene that codes for a centrosome-associated, serine/threonine kinase, the normal function of which is to ensure accurate segregation of chromosomes during mitosis. Amplification of STK15 has been reported in ovarian tumors, suggesting a role in ovarian cancer pathology. STK15 is polymorphic with two single nucleotide substitutions (449t/a and 527g/a) in evolutionarily conserved regions causing amino acid changes (F31I and V57I). Two other nucleotide substitutions (287c/g and 1891g/c) of unknown significance are in 5' and 3' untranslated regions (UTR), respectively. To learn more about the involvement of STK15 in ovarian cancer, we genotyped and haplotyped these polymorphisms in three population-based ovarian cancer case-control studies from the United Kingdom, United States, and Denmark with 1,821 combined cases and 2,467 combined controls and calculated risks for developing ovarian cancer. Genotypes of individual polymorphisms in control groups of the United Kingdom, United States, and Denmark conformed to Hardy-Weinberg equilibrium. In combined cases and combined controls, rare allele frequencies were 0.23 and 0.21 for I31, 0.16 and 0.17 for I57, 0.08 and 0.07 for 5' UTR g, and 0.25 and 0.24 for 3' UTR c, respectively. Using FF common homozygotes of F31I as comparator, there was increased ovarian cancer risk to FI heterozygotes (odds ratio, 1.18; 95% confidence interval, 1.01-1.36), II homozygotes (odds ratio, 1.25; 95% confidence interval, 0.89-1.75), and I31 allele carriers (odds ratio, 1.17; 95% confidence interval, 1.02-1.35) in the combined group data. For either V57I, 5' UTR C/G, or 3' UTR G/C, all genotypic ovarian cancer risks were essentially in unity relative to their respective common homozygotes, VV, cc, or gg. Haplotype analysis of combined group data revealed seven haplotypes with frequencies between 0.02 and 0.5, with c-F-V-g the most common. None of the haplotype-specific risks significantly differed from unity relative to c-F-V-g. These results suggest a model of dominant inheritance of ovarian cancer risk by the I31 allele of F31I and that the I31 allele may be a common ovarian cancer susceptibility allele of low penetrance.

To evaluate the ovarian response cycles of IVF-ET in patients who previously underwent laparoscopic cystectomy for endometriomas. Retrospective study with prospective selection of participants and controls. Instituto de Ginecología y Fertilidad Buenos Aires, Argentina. Thirty-nine patients underwent an operation for ovarian endometriomas by atraumatic removal of the pseudocapsule with minimal bipolar cauterization of small bleeders and an IVF-ET cycle (group A) and 39 control patients of similar age underwent an IVF-ET cycle for tubal factor infertility (group B). Laparoscopic endometrioma cystectomy, IVF-ET cycle. E(2) levels, number of gonadotropin ampoules, follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate. There were no differences in all the parameters studied (E(2) levels, number of follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate) except for the number of gonadotropin ampoules needed for ovarian hyperstimulation, which was significantly higher in group A than in group B. Our results indicate that laparoscopic cystectomy for endometriomas is an appropriate treatment since it did not negatively affect the ovarian response for IVF-ET.

Are progesterone levels after letrozole-associated controlled ovarian stimulation (COS) for fertility preservation in breast cancer patients, lower than after standard in vitro fertilization (IVF) cycles? During the luteal phase of letrozole-associated COS cycles (triggered with human chorionic gonadotrophin (hCG)) progesterone levels are similarly elevated to those obtained after standard COS without letrozole. Current fertility preservation strategies for breast cancer patients include association of COS with the aromatase inhibitor letrozole to harvest several mature oocytes while maintaining low estradiol levels. Data on progesterone levels are however lacking despite growing evidence of the role of progesterone in breast tumorigenesis. This is a prospective observational study comparing estradiol and progesterone levels of 21 breast cancer patients undergoing letrozole-associated COS with 21 infertile patients undergoing standard COS for IVF and/or intra cytoplasmic sperm injection (ICSI). All patients underwent COS with a GnRH antagonist protocol. In the fertility preservation group, ovulation induction was started in the follicular or luteal phase depending on the chemotherapy schedule and in 10 cases a GnRH antagonist was administered during luteal phase to induce luteolysis. Final oocyte maturation was induced by hCG in all patients. Estradiol and progesterone levels were measured on the day of hCG, at oocyte retrieval, and on days 3 and 8 after oocyte retrieval. Hormone levels in fertility preservation patients were compared with those observed in infertility patients. While estradiol levels were significantly lower in the fertility preservation group compared with the control group (P < 0.001), progesterone levels were similar at all times, including patients receiving a GnRH antagonist during the luteal phase. The studied populations (breast cancer and infertile patients) are different, which may induce selection bias. The small sample size limits the study's statistical power and the possibility to perform multivariate analysis. Recruitment of the study and control patients was completed at the same time; however, enrollment of controls started at a later time. While the use of letrozole in fertility preservation patients has a favorable effect on estrogen levels, no benefit is seen for progesterone levels which are high and comparable with progesterone levels after standard COS in IVF patients. As progesterone has been associated with tumor cell proliferation, caution is mandatory. Modified protocols including GnRH agonist triggering should be investigated. © The Author 2015.

Background: Autoantibodies have been detected in sera before diagnosis of cancer leading to interest in their potential as screening/early detection biomarkers. As we have found autoantibodies to MUC1 glycopeptides to be elevated in early-stage breast cancer patients, in this study we analysed these autoantibodies in large population cohorts of sera taken before cancer diagnosis. Methods: Serum samples from women who subsequently developed breast cancer, and aged-matched controls, were identified from UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) and Guernsey serum banks to formed discovery and validation sets. These were screened on a microarray platform of 60mer MUC1 glycopeptides and recombinant MUC1 containing 16 tandem repeats. Additional case–control sets comprised of women who subsequently developed ovarian, pancreatic and lung cancer were also screened on the arrays. Results: In the discovery (273 cases, 273 controls) and the two validation sets (UKCTOCS 426 cases, 426 controls; Guernsey 303 cases and 606 controls), no differences were found in autoantibody reactivity to MUC1 tandem repeat peptide or glycoforms between cases and controls. Furthermore, no differences were observed between ovarian, pancreatic and lung cancer cases and controls. Conclusion: This robust, validated study shows autoantibodies to MUC1 peptide or glycopeptides cannot be used for breast, ovarian, lung or pancreatic cancer screening. This has significant implications for research on the use of MUC1 in cancer detection. PMID:23652307

Accountable care organizations (ACOs) were established to improve care and outcomes for beneficiaries requiring highly coordinated, complex care. The objective of this study was to evaluate the association between hospital ACO participation and the outcomes of major surgical oncology procedures. This was a retrospective cohort study of Medicare beneficiaries older than 65 years who were undergoing a major surgical resection for colorectal, bladder, esophageal, kidney, liver, ovarian, pancreatic, lung, or prostate cancer from 2011 through 2013. A difference-in-differences analysis was implemented to compare the postimplementation period (January 2013 through December 2013) with the baseline period (January 2011 through December 2012) to assess the impact of hospital ACO participation on 30-day mortality, complications, readmissions, and length of stay (LOS). Among 384,519 patients undergoing major cancer surgery at 106 ACO hospitals and 2561 control hospitals, this study found a 30-day mortality rate of 3.4%, a readmission rate of 12.5%, a complication rate of 43.8%, and a prolonged LOS rate of 10.0% in control hospitals and similar rates in ACO hospitals. Secular trends were noted, with reductions in perioperative adverse events in control hospitals between the baseline and postimplementation periods: mortality (percentage-point reduction, 0.1%; P = .19), readmissions (percentage-point reduction, 0.4%; P = .001), complications (percentage-point reduction, 1.0%; P < .001), and prolonged LOS (percentage-point reduction, 1.1%; P < .001). After accounting for these secular trends, this study identified no significant effect of hospital participation in an ACO on the frequency of perioperative outcomes (difference-in-differences estimator P values, .24-.72). Early hospital participation in the Medicare Shared Savings Program ACO program was not associated with greater reductions in adverse perioperative outcomes for patients undergoing major cancer surgery in comparison with control hospitals.

Exercise and chemotherapy-induced amenorrhea.

PubMed

Mathis, Katlynn M; Sturgeon, Kathleen M; Winkels, Renate M; Wiskemann, Joachim; Williams, Nancy I; Schmitz, Kathryn

2018-07-01

Chemotherapy-induced amenorrhea (CIA) is the temporary or permanent loss of menses experienced by premenopausal women undergoing chemotherapy treatment for cancer. Two possible mechanisms through which chemotherapy induces CIA have been identified: systemic endothelial dysfunction, resulting in decreased blood flow to the ovaries, and increased oxidative stress within the ovaries, both of which are proposed to lead to apoptosis of follicles. Endothelial dysfunction in ovarian arteries in women undergoing or who have undergone chemotherapy treatment is characterized by prothrombotic changes and thickening of the vascular wall. These changes result in occlusion of the blood vessels. Oxidative stress is increased and antioxidants decreased in the ovaries secondary to chemotherapy drugs, specifically cyclophosphamide. It is hypothesized that low to moderate intensity aerobic exercise during chemotherapy may prevent these changes and lessen the risk for developing CIA in premenopausal women. Low to moderate intensity aerobic exercise has been shown to improve endothelial function and blood flow in patients with cardiovascular disease-a disease state characterized by endothelial dysfunction and for which patients who have undergone chemotherapy are at increased risk. In mice, moderate intensity aerobic exercise has been shown to decrease the amount of oxidative stress within the ovaries, and in humans, chronic aerobic exercise has been shown to increase antioxidant production systemically. This hypothesis should be tested in both a mouse model, using sedentary and exercising mice treated with chemotherapy drugs that commonly result in CIA, as well as a human model to determine the effects of low to moderate intensity aerobic exercise on ovarian function in premenopausal women undergoing chemotherapy.

In the general population, the risk of developing ovarian cancer is reduced in women who have undergone tubal ligation, hysterectomy, or oophorectomy, although peritoneal cancer can arise after bilateral oophorectomy. In studies from genetic screening clinics, women with mutations in the breast and ovarian susceptibility genes BRCA1 and BRCA2 have been found to have a low risk of peritoneal carcinoma in the first years after bilateral oophorectomy. We assessed the level and persistence of reduction of ovarian (including peritoneal) cancer risk after gynecologic surgeries for women who carry BRCA1/2 mutations but were not selected from high-risk clinics. We identified 1124 Israeli women with incident ovarian cancer or primary peritoneal cancer and tested 847 of them for the three Ashkenazi founder mutations. We compared gynecologic surgery history among all case patients, BRCA1 (n = 187) and BRCA2 (n = 64) carrier case patients, and the non-carrier case patients (n = 598) with that in control subjects drawn from a population registry (n = 2396). We estimated ovarian cancer risk (odds ratios [ORs] with 95% confidence intervals [CIs]) after gynecologic surgery in mutation carriers and non-carriers with logistic regression models. Eight women with primary peritoneal cancer and 128 control subjects reported a previous bilateral oophorectomy (OR = 0.12, 95% CI = 0.06 to 0.24). Other gynecologic surgeries were associated with a 30%-50% reduced risk of ovarian cancer, depending on the type of surgery, with surgery to remove some ovarian tissue associated with the most risk reduction (OR = 0.34, 95% CI = 0.16 to 0.74). Reduced risks were seen in BRCA1/2 carriers and non-carriers. Age at surgery and years since surgery did not affect risk reductions. Both BRCA1/2 mutation carriers and non-carriers have reduced risk of ovarian or peritoneal cancer after gynecologic surgery. The magnitude of the reduction depends upon the type and extent of surgery.

In vitro and observational epidemiological studies suggest that vitamin D may play a role in cancer prevention. However, the relationship between vitamin D and ovarian cancer is uncertain, with observational studies generating conflicting findings. A potential limitation of observational studies is inadequate control of confounding. To overcome this problem, we used Mendelian randomization (MR) to evaluate the association between single nucleotide polymorphisms (SNPs) associated with circulating 25-hydroxyvitamin D [25(OH)D] concentration and risk of ovarian cancer. We employed SNPs with well-established associations with 25(OH)D concentration as instrumental variables for MR: rs7944926 (DHCR7), rs12794714 (CYP2R1) and rs2282679 (GC). We included 31 719 women of European ancestry (10 065 cases, 21 654 controls) from the Ovarian Cancer Association Consortium, who were genotyped using customized Illumina Infinium iSelect (iCOGS) arrays. A two-sample (summary data) MR approach was used and analyses were performed separately for all ovarian cancer (10 065 cases) and for high-grade serous ovarian cancer (4121 cases). The odds ratio for epithelial ovarian cancer risk (10 065 cases) estimated by combining the individual SNP associations using inverse variance weighting was 1.27 (95% confidence interval: 1.06 to 1.51) per 20 nmol/L decrease in 25(OH)D concentration. The estimated odds ratio for high-grade serous epithelial ovarian cancer (4121 cases) was 1.54 (1.19, 2.01). Genetically lowered 25-hydroxyvitamin D concentrations were associated with higher ovarian cancer susceptibility in Europeans. These findings suggest that increasing plasma vitamin D levels may reduce risk of ovarian cancer. © The Author 2016; all rights reserved.

A suitable culture system is important for follicle growth in adult bovine ovarian tissue. This study aimed to assess the avian chorioallantoic membrane (CAM) for short-term culture of adult bovine ovarian tissues compared with a traditional in vitro culture system. Ovarian cortical tissues (1-2 mm 3 ), collected from slaughtered adult cows, were randomly assigned to control, CAM or in vitro culture groups. In the control group, ovarian tissues were fixed with paraformaldehyde without culture. In CAM and in vitro culture groups, the ovarian tissues were cultured for up to 5 days and then fixed. Ovarian tissues were examined on culture days 0, 1, 3 and 5 for angiogenesis, follicle morphology and growth. In all groups, primordial and growing (healthy and atretic) follicle densities were determined. In the CAM culture, the avian blood vessel density increased (p < 0.01) over time with a decline (p < 0.001) in the bovine blood vessel density. Healthy primordial, atretic primordial and healthy growing follicle densities were higher (p < 0.05) in CAM-cultured ovarian tissues than in vitro-cultured tissues. Regardless of the culture system, the density of healthy primordial follicles decreased (p < 0.001) over time with an increase in healthy growing follicles on day 3 (p < 0.01) and an increase in atretic (primordial and growing) follicles during the 5-day culture period (p < 0.001). The proportions of healthy primordial and atretic growing follicles were also affected by culture day (p < 0.001). The CAM culture in chick embryos supported the bovine ovarian tissue grafts for 3 days demonstrating that CAM can be used as a satisfactory short-term culture system to assess ovarian tissue health, and to study follicle activation and development.

Ovarian cancer is the second most common gynaecological malignancy and was diagnosed in over 7,000 women in 2011 in the UK. There are currently no reliable biomarkers available for use in a regular screening assay for ovarian cancer and due to characteristic late presentation (78% in stages III and IV) ovarian cancer has a low survival rate (35% after 10 years). The mTOR pathway is a central regulator of growth, proliferation, apoptosis and angiogenesis; providing balance between available resources such as amino acids and growth factors, and stresses such as hypoxia, to control cellular behaviour accordingly. Emerging data links mTOR with the aetiopathogenesis of ovarian cancer. We hypothesised that mTOR inhibitors could play a therapeutic role in ovarian cancer treatment. In this study we began by validating the expression of four main mTOR pathway components, mTOR, DEPTOR, rictor and raptor, at gene and protein level in in vitro models of endometrioid (MDAH-2774) and clear cell (SKOV3) ovarian cancer using qPCR and ImageStream technology. Using a wound healing assay we show that inhibition of the mTOR pathway using rapamycin, rapalogues, resveratrol and NVP BEZ-235 induces a cytostatic and not cytotoxic response up to 18 h in these cell lines. We extended these findings up to 72 h with a proliferation assay and show that the effects of inhibition of the mTOR pathway are primarily mediated by the dephosphorylation of p70S6 kinase. We show that mTOR inhibition does not involve alteration of mTOR pathway components or induce caspase 9 cleavage. Preclinical studies including ovarian tissue of ovarian cancer patients, unaffected controls and patients with unrelated gynaecological conditions show that DEPTOR is reliably upregulated in ovarian cancer.

Objectives To compare the effectiveness of in vitro fertilisation with single embryo transfer or in vitro fertilisation in a modified natural cycle with that of intrauterine insemination with controlled ovarian hyperstimulation in terms of a healthy child. Design Multicentre, open label, three arm, parallel group, randomised controlled non-inferiority trial. Setting 17 centres in the Netherlands. Participants Couples seeking fertility treatment after at least 12 months of unprotected intercourse, with the female partner aged between 18 and 38 years, an unfavourable prognosis for natural conception, and a diagnosis of unexplained or mild male subfertility. Interventions Three cycles of in vitro fertilisation with single embryo transfer (plus subsequent cryocycles), six cycles of in vitro fertilisation in a modified natural cycle, or six cycles of intrauterine insemination with ovarian hyperstimulation within 12 months after randomisation. Main outcome measures The primary outcome was birth of a healthy child resulting from a singleton pregnancy conceived within 12 months after randomisation. Secondary outcomes were live birth, clinical pregnancy, ongoing pregnancy, multiple pregnancy, time to pregnancy, complications of pregnancy, and neonatal morbidity and mortality Results 602 couples were randomly assigned between January 2009 and February 2012; 201 were allocated to in vitro fertilisation with single embryo transfer, 194 to in vitro fertilisation in a modified natural cycle, and 207 to intrauterine insemination with controlled ovarian hyperstimulation. Birth of a healthy child occurred in 104 (52%) couples in the in vitro fertilisation with single embryo transfer group, 83 (43%) in the in vitro fertilisation in a modified natural cycle group, and 97 (47%) in the intrauterine insemination with controlled ovarian hyperstimulation group. This corresponds to a risk, relative to intrauterine insemination with ovarian hyperstimulation, of 1.10 (95% confidence interval 0.91 to 1.34) for in vitro fertilisation with single embryo transfer and 0.91 (0.73 to 1.14) for in vitro fertilisation in a modified natural cycle. These 95% confidence intervals do not extend below the predefined threshold of 0.69 for inferiority. Multiple pregnancy rates per ongoing pregnancy were 6% (7/121) after in vitro fertilisation with single embryo transfer, 5% (5/102) after in vitro fertilisation in a modified natural cycle, and 7% (8/119) after intrauterine insemination with ovarian hyperstimulation (one sided P=0.52 for in vitro fertilisation with single embryo transfer compared with intrauterine insemination with ovarian hyperstimulation; one sided P=0.33 for in vitro fertilisation in a modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation). Conclusions In vitro fertilisation with single embryo transfer and in vitro fertilisation in a modified natural cycle were non-inferior to intrauterine insemination with controlled ovarian hyperstimulation in terms of the birth of a healthy child and showed comparable, low multiple pregnancy rates.

Objective Some forms of ovarian neoplasms may be preventable through the removal of precursor lesions. We assessed risk associated with a prior diagnosis of, and ovarian surgery following, ovarian cysts and endometriosis, with a focus on characterizing risk among tumor subgroups. Methods Information was collected during in-person interviews with 812 women with ovarian cancer diagnosed in western Washington State from 2002–2005 and 1,313 population-based controls. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Results The risk of a borderline mucinous ovarian tumor associated with a history of an ovarian cyst was increased (OR=1.7, 95% CI 1.0–2.8) but did not vary notably according to receipt of subsequent ovarian surgery. While risk of invasive epithelial ovarian cancer was slightly increased among women with a cyst who had no subsequent ovarian surgery, it was reduced when a cyst diagnosis was followed by surgery (OR= 0.6, 95% CI 0.4–0.9). This reduction in risk was most evident for serous invasive tumors. Women with a history of endometriosis had a three-fold increased risk of endometrioid and clear cell invasive tumors, with a lesser risk increase among women who underwent subsequent ovarian surgery. Conclusions Our results suggest differences in the relation of ovarian cysts and endometriosis with risk of specific subtypes of ovarian cancer, as well as the possibility that ovarian surgery in women with these conditions may lower the risk of invasive disease.

Recent publications have shown a negative influence of SLE on female ovarian reserve. Other authors have not found a significant impact of Crohn's disease or early RA on anti-Müllerian hormone (AMH) levels. This study aimed to investigate the potential effect of Behçet's disease (BD), RA and SpA on ovarian reserve as reflected by serum AMH levels. Serum samples from 33 RA, 32 SpA and 30 BD patients without previous cytotoxic treatment were analysed and compared with age-matched, healthy controls. AMH was quantified using a standard ELISA with a standard value of 1-8 ng/ml; values <1 ng/ml defined a reduced ovarian reserve. Median age was 26, 28.5 and 33 years and median disease duration was 6, 5.9 and 7 years for RA, SpA and BD patients, respectively. Compared with healthy controls, patients had significantly reduced AMH levels, with a median value for RA of 1.8 ng/ml (control 2.4 ng/ml; P = 0.009), for SpA of 1.5 ng/ml (control 2.3 ng/ml; P = 0.013) and for BD of 1.1 ng/ml (control 1.9 ng/ml; P = 0.007). HLA-B27 had a negative influence on ovarian reserve in SpA patients, whereas other serological parameters did not in the other diseases. This is the first study to show a reduced ovarian reserve in patients with RA, SpA or BD. Together with our findings in SLE, we conclude a negative influence of chronic rheumatic diseases on ovarian reserve. © The Author 2015.

In this report, we propose a study protocol capable of improving IVF outcomes in subfertile women with expected normal ovarian response. This proposal derives from conflicting published data and observations in our daily practice, concerning the negative impact of progesterone (P4) elevation at the day of oocyte triggering on pregnancy outcomes. Our hypothesis points to the combination of two previous "suspects" of reduced success after assisted reproduction techniques (ART) - the endometrium ultrasonographic parameters and P4 elevation at the day of oocyte triggering on their impact on pregnancy outcomes. Up-to-the minute data show that, there is a different impact of elevated P4 in fresh, frozen and donor cycles, whereas there are plenty of reports pointing to a different endometrial gene expression on different P4 measurements. Gaps in the literature are linked with a variation of the measurements of P4, its cycle-to-cycle reproducibility, the different cut-off levels used, the impact of various protocols of ovarian stimulation and the limitations of systematic reviews originating from the initial studies. Our hypothesis states that the combination of P4 values and endometrial ultrasound parameters at the day of oocyte triggering can affect clinical pregnancy rates in normal responders undergoing ART.

Animal and experimental data suggest that anti-Müllerian hormone (AMH) serves as a marker of ovarian reserve and inhibits the growth of ovarian tumors. However, few epidemiologic studies have examined the association between AMH and ovarian cancer risk. We conducted a nested case-control study of 302 ovarian cancer cases and 336 matched controls from nine cohorts. Prediagnostic blood samples of premenopausal women were assayed for AMH using a picoAMH enzyme-linked immunosorbent assay. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using multivariable-adjusted conditional logistic regression. AMH concentration was not associated with overall ovarian cancer risk. The multivariable-adjusted OR (95% CI), comparing the highest to the lowest quartile of AMH, was 0.99 (0.59-1.67) (P trend : 0.91). The association did not differ by age at blood draw or oral contraceptive use (all P heterogeneity : ≥0.26). There also was no evidence for heterogeneity of risk for tumors defined by histologic developmental pathway, stage, and grade, and by age at diagnosis and time between blood draw and diagnosis (all P heterogeneity : ≥0.39). In conclusion, this analysis of mostly late premenopausal women from nine cohorts does not support the hypothesized inverse association between prediagnostic circulating levels of AMH and risk of ovarian cancer. © 2017 UICC.

New serological biomarkers for early detection and clinical management of ovarian cancer are urgently needed, and many candidates have been reported. A major challenge frequently encountered when validating candidates in patients is establishing quantitative assays that distinguish between highly homologous proteins. The current study tested whether multiple members of two recently discovered ovarian cancer biomarker protein families, chloride intracellular channel (CLIC) proteins and tropomyosins (TPM), were detectable in ovarian cancer patient sera. A multiplexed, label-free multiple reaction monitoring (MRM) assay was established to target peptides specific to all detected CLIC and TPM family members, and their serum levels were quantitated for ovarian cancer patients and non-cancer controls. In addition to CLIC1 and TPM1, which were the proteins initially discovered in a xenograft mouse model, CLIC4, TPM2, TPM3, and TPM4 were present in ovarian cancer patient sera at significantly elevated levels compared with controls. Some of the additional biomarkers identified in this homolog-centric verification and validation approach may be superior to the previously identified biomarkers at discriminating between ovarian cancer and non-cancer patients. This demonstrates the importance of considering all potential protein homologs and using quantitative assays for cancer biomarker validation with well-defined isoform specificity. PMID:23792823

Anti-Mullerian Hormone (AMH) is a useful endocrine marker for assessing the ovarian reserve. AMH serum level reflects the number of follicles that have made the transition from the primordial pool into the growing follicle pool, and it is not controlled by gonadotropins. The present study was conducted to correlate serum AMH levels with Polycystic Ovarian Syndrome (PCOS) and type of treatment protocol. Serum AMH levels were performed in the early follicular phase (on 2 nd day of menstrual cycle) both in infertile females including PCOS and control women. The results were analyzed in relation to age, Body Mass Index (BMI), ovarian volume, serum Follicle Stimulating Hormone (FSH) levels, Antral Follicle Count (AFC), type of treatment protocols and also in association with PCOS patients. The serum levels of AMH were measured in all the participants on 2 nd day of menstrual cycle using ultra sensitive Enzyme Linked Immunosorbent Assay (ELISA). The plasma AMH levels were significantly higher in women with polycystic ovarian syndrome. The significant association was seen between FSH and AFC with AMH. However, no significant association was observed between AMH levels with age, BMI, ovarian volume and type of treatment protocols. The serum AMH measurement was significantly higher in PCOS patients. No association with type of treatment protocol was obtained.

Background Acrylamide is a probable human carcinogen formed during cooking of starchy foods. Two large prospective cohort studies of dietary acrylamide intake and ovarian cancer risk observed a positive association, although two other studies reported no association. Methods We measured acrylamide exposure using red blood cell acrylamide and glycidamide hemoglobin adducts among women in two large prospective cohorts: the Nurses’ Health Study and Nurses’ Health Study II. Between blood collection and 2010, we identified 263 incident cases of epithelial ovarian cancer, matching two controls per case. We used logistic regression models to examine the association between acrylamide exposure and ovarian cancer risk, adjusting for matching factors, family history of ovarian cancer, tubal ligation, oral contraceptive use, body mass index (BMI), parity, alcohol intake, smoking, physical activity, and caffeine intake. Results The multivariate-adjusted relative risk (RR) of ovarian cancer comparing the highest versus lowest tertile of total acrylamide adducts was 0.79 (95% CI: 0.50–1.24, P trend = 0.08). The comparable RR of ovarian cancer among non-smokers at blood draw was 0.85 (95% CI: 0.57–1.27, P trend =0.14). The association did not differ by tumor histology (serous invasive versus not), P for heterogeneity=0.41. Individual adduct types (acrylamide or glycidamide) were not associated with risk. Conclusions We observed no evidence that acrylamide exposure as measured by adducts to hemoglobin is associated with an increased risk of ovarian cancer. Impact Our finding indicates that acrylamide intake may not increase risk of ovarian cancer. PMID:23417989

Impact of systemic lupus erythematosus (SLE) on fertility may be negative, and ovarian function can be also reduced by autoimmune oophoritis. In this article, we evaluated the ovarian reserve of pre-menopausal women firstly diagnosed with systemic lupus erythematosus (SLE). This was a prospective controlled study which included twenty women with SLE and twenty healthy women as controls in the reproductive age. Basal levels of FSH, estradiol (E2), and LH on cycle day 3 were measured. All participants underwent transvaginal ultrasonographic examination on the third day of their menstrual periods for the determination of ovarian volume (OV) and total antral follicle count (AFC). A significant difference in FSH, LH, and E2 levels was observed between women with SLE and healthy controls. There was a statistically significant reduction in total AFC and OV in SLE group. Age was associated negatively with AFC, whereas positively with FSH and LH. Menstrual irregularity was significantly higher in SLE patients than control. AFC was the most reliable test to show the menstrual irregularity and negatively correlated each other in women with SLE. In this preliminary study, the first in SLE patients, we illustrated that women with SLE had lower ovarian reserves and higher menstrual irregularity compared with healthy controls according to hormonal and ultrasonographical evaluation. © 2014 John Wiley & Sons A/S.

Objective To test the hypothesis that women with spontaneous primary ovarian insufficiency differ from control women with regard to perceived social support and to investigate the relationship between perceived social support and self-esteem. Design Cross-sectional Setting Mark O. Hatfield Clinical Research Center, National Institutes of Health. Patient(s) Women diagnosed with spontaneous primary ovarian insufficiency (N=154) at a mean age of 27 years and healthy control women (N=63). Intervention(s) Administration of validated self-reporting instruments. Main Outcome Measure(s) Personal Resource Questionnaire-85 (PRQ85), Rosenberg Self-Esteem Scale Result(s) Women with primary ovarian insufficiency had significantly lower scores than controls on the perceived social support scale and the self-esteem scale. The findings remained significant after modeling with multivariate regression for differences in age, marital status, and having children. In patients there was a significant positive correlation between self-esteem scores and perceived social support. We found no significant differences in perceived social support or self-esteem related to marital status, whether or not they had children, or time since diagnosis. Conclusion(s) This evidence supports the need for prospective controlled studies. Strategies to improve social support and self-esteem might provide a therapeutic approach to reduce the emotional suffering that accompanies the life-altering diagnosis of spontaneous primary ovarian insufficiency.

To evaluate the effect of recombinant LH in assisted reproduction technology (ART) cycles in patients of advanced reproductive age. A systematic review and meta-analysis. Published randomized controlled clinical trials comparing recombinant LH plus recombinant FSH versus recombinant FSH only in patients of advanced reproductive age. Patients 35 years and older undergoing assisted reproduction. Recombinant LH plus recombinant FSH controlled ovarian hyperstimulation (COH) versus recombinant FSH stimulation only in assisted reproduction cycles. Implantation and clinical pregnancy. Seven trials were identified that met inclusion criteria and comprised 902 assisted reproduction technology cycles. No differences in serum E(2) on the day of hCG administration were reported in any trials. Two trials reported lower oocyte yield and one trial reported lower metaphase II oocyte yield in the recombinant LH-supplemented group. One trial reported higher fertilization rates in the recombinant LH-supplemented group. In a fixed effect model, implantation was higher in the recombinant LH-supplemented group (odds ratio 1.36, 95% confidence interval 1.05-1.78). Similarly, clinical pregnancy was increased in the recombinant LH-supplemented group (odds ratio 1.37, 95% confidence interval 1.03-1.83). The addition of recombinant LH to ART cycles may improve implantation and clinical pregnancy in patients of advanced reproductive age. Copyright © 2012 American Society for Reproductive Medicine.

We aimed to investigate the ovarian function and reserve in euthyroid adolescents (TSH < 2.5 mIU/L) diagnosed with Hashimoto thyroiditis (HT). This case-control study included 30 adolescent girls (mean age 15.1 ± 1.4 years) newly diagnosed as HT with presence of high thyroid antibodies with gland heterogeneity in ultrasound and age-matched 30 healthy female subjects. Anti-ovarian antibody (AOAb), LH/FSH ratio, estradiol, anti-mullerian hormone (AMH), inhibin-B, total testosterone, antral follicle count, ovarian volumes and uterine length were measured. The clinical, laboratory, and ultrasound data of the HT and control groups were compared. There were no significant differences between the girls with HT and healthy controls in relation to LH/FSH ratio, estradiol and inhibin-B levels. AOAb (p = 0.02), AMH (p = 0.007) and total testosterone levels were higher in HT group than the control group (p = 0.03). AOAb level was found to be positively correlated with LH/FSH ratio (p = 0.03), AMH (p = 0.01) and inhibin-B (p < 0.001) in HT group. This study demonstrated that the adolescent girls diagnosed with autoimmune thyroiditis had normal ovarian reserve based on measurements of AMH, inhibin B, FSH, LH/FSH ratio, estradiol and antral follicle counts.

Angiogenesis has been found to be among the most important factors in the pathogenesis of endometriosis. The formation of new blood vessels is critical for the survival of newly implanted endometriotic foci. The use of 3-D power Doppler allows for the demonstration of the dynamic vascular changes that occur during the process of in vitro fertilization (IVF). We aimed to evaluate the effect of ovarian endometrioma on uterine and ovarian blood flow in infertile women. In a case-control study at a university teaching hospital, 138 women with unilateral ovarian endometrioma scheduled for IVF were compared to 138 women with male-factor or unexplained infertility. In the mid-luteal (peri-implantation) phase of the cycle, endometrial thickness, uterine and ovarian artery pulsatility index and resistance index, endometrial and ovarian volume, 3-D power Doppler vascularization index (VI), flow index (FI), and vascularization FI (VFI) values were measured in both groups. There were no significant differences ( P >0.05) in endometrial thickness, uterine ovarian artery pulsatility index and resistance index, endometrial and ovarian volume, or VI, FI, and VFI between the two groups. Furthermore, the endometrial and ovarian Doppler indices were not influenced by endometrioma size. No significant differences were observed in the ovarian Doppler indices between endometrioma-containing ovaries and contralateral ovaries. Ovarian endometrioma is not associated with impaired endometrial and ovarian blood flows in infertile women scheduled for IVF, and it is not likely to affect endometrial receptivity or ovarian function through a vascular mechanism.

Proteasome ubiquitin system is the important system of intracellular proteolysis. The activity of the proteasomes may undergo changes during cancer development. We studied the chymotrypsin-like activity of proteasomes, their subunit composition, and their association with tumor stage in breast cancer, head and neck squamous cell carcinoma, endometrial cancer, renal cancer, bladder cancer, stomach cancer, ovarian cancer, and colorectal cancer. The increase in chymotrypsin-like activity of proteasomes and decrease in total proteasome pool compared with adjacent tissues were shown in all malignant tumors excluding kidney cancer. The increase in chymotrypsin-like activity of proteasomes was found in primary tumors with all types of metastasis: lymphogenous of head and neck squamous cell carcinoma, intraperitoneal metastasis of ovarian cancer, hematogenous metastasis colorectal cancer. The exception was kidney cancer, in which there was a decrease in chymotrypsin-like activity with distant metastasis.

Endometriosis is a chronic disease. The pathogenesis is actually still unclear. Endometriosis is responsible for infertility and/or pelvic pain. One of the most important features of the disease is the heterogeneity (clinical and anatomical). Among the different phenotypes of endometriosis, the ovarian endometrioma seems to most important lesion in the management of endometriosis-related infertility. Surgical treatment is associated to a decrease of the ovarian reserve and a potential detrimental effect on in vitro fecondation (IVF) outcomes. Thus, the choice between conservative or surgical management of endometrioma before IVF is actually debated. The advantages and drawback of surgical and conservative management should be discussed before to plan the treatment. In the present review, we aimed at assessing the risks of a conservative management of endometrioma as compared to surgery before IVF. Copyright © 2017. Published by Elsevier Masson SAS.

In this study, the relationship between ovarian function and ovarian limited dose in radiotherapy was evaluated in young patients with cervical cancer who underwent ovarian transposition (Fig1B). Moreover, the novel ovarian dose limit for a better preservation of ovarian function in intensity-modulated radiation therapy (IMRT) was determined. We retrospectively analyzed data from 86 patients with cervical cancer who received radical hysterectomy and ovarian transposition from January 2013 to June 2015. In agreement with the National Comprehensive Cancer Network Guidelines (NCCN) for Cervical Cancer Version 2.2015, 65 patients with pathological high-risk factors were administered adjuvant radiotherapy-20 of them received three-dimensional conformal radiotherapy (Observation Group A), 24 patients received IMRT with no limitation on radiation dose to ovaries (Observation Group B), and 21 patients underwent IMRT with limited radiation dose(V 10 <20%) to ovaries (Observation Group C). Twenty-one patients without any predetermined high-risk factors did not received radiation therapy (Control Group D). Patients from all four groups were followed up, and sex hormone levels (E 2 , P, follicle-stimulating hormone [FSH], LH) before radiation, postradiation, 3 month, and 6 month after the radiation therapy were measured by electrochemiluminescence immunoassay. Subsequently, changes in sex hormone levels in all four groups of patients at various time points were analyzed. The levels of sexual hormones (E 2 , P, FSH, LH) before radiation, postradiation, 3 month, and 6 month after the radiation therapy in patients from all three observation groups were significantly lower than those in patients of the control group (P < 0.05). There was no statistically significant difference in the levels of sex hormones in patients of the control group at different time points (P > 0.05). Within each observation group, there was a statistically significant difference in the sex hormone levels in patients before the radiation and after the radiation (P < 0.05); however, when data from all three observation groups were compared, only the difference in the levels of FSH and LH between the patients from Group A and Group C was statistically significant (P < 0.05). The results of receiver-operating characteristic (ROC) curve analysis suggested that limiting ovarian radiation dose to V 7.5  < 26% in IMRT prevents the disruption of ovarian function (area under ROC curve was 0.740, confidence interval [CI] = 0.606-0.874). In young patients with cervical cancer who underwent radical hysterectomy and ovarian transposition without receiving adjuvant radiotherapy, ovarian endocrine function was well preserved. In patients who received any type of postoperative radiotherapy, ovarian function was affected, suggesting that the standard ovarian limited dose used in IMRT disrupted ovarian function. The results of the ROC curve analysis suggested that the new optimal dose limit of V 7.5  < 26% should be used in IMRT to preserve ovarian function (P = 0.003). © 2017 The Authors.

CA-125 has been a valuable marker for the follow-up of ovarian cancer patients but it is not sensitive enough to be used as diagnostic marker. We had already used secretomic methods to identify proteins differentially secreted by serous ovarian cancer cells compared to healthy ovarian cells. Here, we evaluated the secretion of these proteins by ovarian cancer cells during the follow-up of one patient. Proteins that correlated with CA-125 levels were screened using serum samples from ovarian cancer patients as well as benign and healthy controls. Tenascin-X secretion was shown to correlate with CA-125 value in the initial case study. The immunohistochemical detection of increased amount of tenascin-X in ovarian cancer tissues compared to healthy tissues confirms the potent interest in tenascin-X as marker. We then quantified the tenascin-X level in serum of patients and identified tenascin-X as potent marker for ovarian cancer, showing that secretomic analysis is suitable for the identification of protein biomarkers when combined with protein immunoassay. Using this method, we determined tenascin-X as a new potent marker for serous ovarian cancer. PMID:26090390

The incidences of metastatic brain tumors from gynecologic cancer have increased. The results of Gamma Knife surgery (GKS) for the treatment of patients with brain metastases from gynecologic cancer (ovarian, endometrial, and uterine cervical cancers) were retrospectively analyzed to identify the efficacy and prognostic factors for local tumor control and survival. The medical records were retrospectively reviewed of 70 patients with 306 tumors who underwent GKS for brain metastases from gynecologic cancer between January 1995 and December 2013 in our institution. The primary cancers were ovarian in 33 patients with 147 tumors and uterine in 37 patients with 159 tumors. Median tumor volume was 0.3 cm(3). Median marginal prescription dose was 20 Gy. The local tumor control rates were 96.4% at 6 months and 89.9% at 1 year. There was no statistically significant difference between ovarian and uterine cancers. Higher prescription dose and smaller tumor volume were significantly correlated with local tumor control. Median overall survival time was 8 months. Primary ovarian cancer, controlled extracranial metastases, and solitary brain metastasis were significantly correlated with satisfactory overall survival. Median activities of daily living (ADL) preservation survival time was 8 months. Primary ovarian cancer, controlled extracranial metastases, and higher Karnofsky Performance Status score were significantly correlated with better ADL preservation. GKS is effective for control of tumor progression in patients with brain metastases from gynecologic cancer, and may provide neurologic benefits and preservation of the quality of life.

Does ovarian ageing increase the number of heteroplasmic mitochondrial DNA (mtDNA) point mutations in oocytes? Our results suggest that oocytes are not subject to the accumulation of mtDNA point mutations during ovarian ageing. Ageing is associated with the alteration of mtDNA integrity in various tissues. Primary oocytes, present in the ovary since embryonic life, may accumulate mtDNA mutations during the process of ovarian ageing. This was an observational study of 53 immature oocyte-cumulus complexes retrieved from 35 women undergoing IVF at the University Hospital of Angers, France, from March 2013 to March 2014. The women were classified in two groups, one including 19 women showing signs of ovarian ageing objectified by a diminished ovarian reserve (DOR), and the other, including 16 women with a normal ovarian reserve (NOR), which served as a control group. mtDNA was extracted from isolated oocytes, and from their corresponding cumulus cells (CCs) considered as a somatic cell compartment. The average mtDNA content of each sample was assessed by using a quantitative real-time PCR technique. Deep sequencing was performed using the Ion Torrent Proton for Next-Generation Sequencing. Signal processing and base calling were done by the embedded pre-processing pipeline and the variants were analyzed using an in-house workflow. The distribution of the different variants between DOR and NOR patients, on one hand, and oocyte and CCs, on the other, was analyzed with the generalized mixed linear model to take into account the cluster of cells belonging to a given mother. There were no significant differences between the numbers of mtDNA variants between the DOR and the NOR patients, either in the oocytes (P = 0.867) or in the surrounding CCs (P = 0.154). There were also no differences in terms of variants with potential functional consequences. De-novo mtDNA variants were found in 28% of the oocytes and in 66% of the CCs with the mean number of variants being significantly different (respectively 0.321, SD = 0.547 and 1.075, SD = 1.158) (P < 0.0001). Variants with a potential functional consequence were also overrepresented in CCs compared with oocytes (P = 0.0019). N/A. Limitations may be due to the use of immature oocytes discarded during the assisted reproductive technology procedure, the small size of the sample, and the high-throughput sequencing technology that might not have detected heteroplasmy levels lower than 2%. The alteration of mtDNA integrity in oocytes during ovarian ageing is a recurring question to which our pilot study suggests a reassuring answer.

This study examined the role of the immunosuppressive enzyme indoleamine-2,3-dioxygenase (IDO) in ovarian cancer progression, and the possible application of this enzyme as a target for ovarian cancer therapy. We transfected a short hairpin RNA vector targeting IDO into the human ovarian cancer cell line SKOV-3, that constitutively expresses IDO and established an IDO downregulated cell line (SKOV-3/shIDO) to determine whether inhibition of IDO mediates the progression of ovarian cancer. IDO downregulation suppressed tumor growth and peritoneal dissemination in vivo, without influencing cancer cell growth. Moreover, IDO downregulation enhanced the sensitivity of cancer cells to natural killer (NK) cells in vitro, and promoted NK cell accumulation in the tumor stroma in vivo. These findings indicate that downregulation of IDO controls ovarian cancer progression by activating NK cells, suggesting IDO targeting as a potential therapy for ovarian cancer. PMID:22179492

This study aimed to evaluate whether the addition of resveratrol to vitrification/thawing medium improves the cryotolerance of preantral follicles enclosed in bovine ovarian fragments. Ovarian fragments were obtained from bovine fetuses and distributed to the following groups: fresh ovarian fragments (control), vitrified (VIT), and vitrified with resveratrol (VIT + RESV). Overall, the mean percentage of normal follicles was greater (P < 0.05) in the VIT + RESV compared to the VIT group. Moreover, the probability of finding normal follicles was 2.5 greater (P < 0.05) in the VIT + RESV group. In class comparison, the primordial and transitional follicles have ∼3.0 times (P < 0.05) greater odds of being normal after vitrification compared to the secondary follicles. Additionally, a negative association (P < 0.05) was observed between the proportion of viable follicles and the stage of follicular development. ROS levels were similar (P > 0.05) between the VIT and VIT + RESV groups, and both were lower (P < 0.05) than the control group. The tissue viability in the VIT + RESV group was similar (P > 0.05) to the control group. In summary, the resveratrol provided greater ovarian tissue viability and has a positive effect against degeneration of preantral follicles enclosed in ovarian fragments.

The objective was to investigate the use of powdered coconut water (ACP)-based medium for short-term preservation of canine preantral follicles. Pairs of ovaries from mongrel bitches (n=9) were divided into fragments. One ovarian fragment, treated as a fresh control, was immediately fixed for histological analysis, whereas the other six ovarian fragments were stored either in phosphate-buffered saline (PBS; control group) or ACP medium in isothermal Styrofoam boxes containing biological ice packs. The boxes were sealed and opened only after 12, 24, or 36h. After opening each box, the ovarian fragments were submitted to histological analysis. In total, 12,302 preantral follicles were evaluated, with 64.5% primordial, 33.3% primary, and 2.3% secondary follicles. There were multiple oocytes in 1.3% of the follicles analyzed. At 24h, ACP was more efficient in preserving follicular morphology than PBS (P<0.05). Compared with the fresh control group, a significant reduction in the percentage of morphologically normal ovarian follicles was observed for PBS, starting at 24h; however, the decline started only at 36h for the ACP medium. During the experiment, the temperature inside the isothermal boxes increased from 3 to 9 degrees C (P<0.05), despite a constant room temperature. In conclusion, powdered coconut water (ACP) was an appropriate medium for short-term storage of canine preantral ovarian follicles.

To investigate the association between fruit and vegetable consumption and the risk of epithelial ovarian cancer in southern Chinese women. A case-control study was undertaken in Guangzhou, Guangdong Province, between 2006 and 2008. Participants were 500 incident ovarian cancer patients and 500 hospital-based controls. Information on habitual fruit and vegetable consumption was obtained by face-to-face interview using a validated and reliable food frequency questionnaire. Unconditional logistic regression analyses were performed to assess the association between fruit and vegetable intakes and the ovarian cancer risk. The mean fruit and vegetable daily intakes of ovarian cancer patients (324.2g (SD 161.9) and 582.7 g (SD 250.2)) were significantly lower (p<0.001) than those of controls (477.3g (SD 362.1) and 983.3g (SD 739.9)). The adjusted odds ratios were 0.30 (95% confidence interval (CI) 0.21 to 0.44) and 0.07 (95% CI 0.04 to 0.12) for more than 490 g of fruits and 970 g of vegetables per day, relative to at most 320 g and 690 g per day, respectively. With the exception of lycopene, substantial risk reductions were evident for a variety of nutrients derived from fruits and vegetables. Consumption of fruits and vegetables was inversely associated with the incidence of epithelial ovarian cancer in southern Chinese women. © 2013.

The aim of this study was to evaluate the concentration of vascular endothelial growth factor (VEGF) in follicular fluid and in granulosa cell cultures in relation to the degree of apoptosis in granulosa cells from patients with different types of ovarian response to controlled ovarian hyperstimulation. We studied 30 women who underwent controlled ovarian hyperstimulation and oocyte retrieval. Group A comprised patients with 1-4 follicles (n = 10), group B patients with 5-14 follicles (n = 10) and group C patients with >15 follicles (n = 10). Mean (+/-SD) VEGF concentrations in follicular fluid were 1232 +/- 209, 813 +/- 198 and 396 +/- 103 pg/ml for groups A, B and C respectively (P > 0.01). Concentrations of VEGF in granulosa cell supernatant were 684 +/- 316, 1101 +/- 295 and 1596 +/- 227 pg/ml respectively (P < 0.05). Percentages of apoptotic cells in granulosa cells culture was 55.02 +/- 7.5, 23.98 +/- 4.4 and 14.2 +/- 2.3% respectively (A versus B, P < 0.01, A versus C, P < 0.006, B versus C, NS). Our findings showed that in patients with decreased ovarian response to controlled ovarian hyperstimulation, follicular fluid VEGF concentration is elevated, the concentration from granulosa cells culture supernatant is decreased and the percentage of apoptotic granulosa cells is increased, while opposite findings occurred in patients with normal or hyper-responses.

Background: Polycystic ovary syndrome (PCOS), and one of its distinguishing characteristics, oligomenorrhea, have both been associated with ovarian cancer risk in some but not all studies. However, these associations have been rarely examined by ovarian cancer histotypes, which may explain the lack of clear associations reported in previous studies. Methods: We analyzed data from 14 case-control studies including 16,594 women with invasive ovarian cancer ( n = 13,719) or borderline ovarian disease ( n = 2,875) and 17,718 controls. Adjusted study-specific ORs were calculated using logistic regression and combined using random-effects meta-analysis. Pooled histotype-specific ORs were calculated using polytomous logistic regression. Results: Women reporting menstrual cycle length >35 days had decreased risk of invasive ovarian cancer compared with women reporting cycle length ≤35 days [OR = 0.70; 95% confidence interval (CI) = 0.58-0.84]. Decreased risk of invasive ovarian cancer was also observed among women who reported irregular menstrual cycles compared with women with regular cycles (OR = 0.83; 95% CI = 0.76-0.89). No significant association was observed between self-reported PCOS and invasive ovarian cancer risk (OR = 0.87; 95% CI = 0.65-1.15). There was a decreased risk of all individual invasive histotypes for women with menstrual cycle length >35 days, but no association with serous borderline tumors ( P heterogeneity = 0.006). Similarly, we observed decreased risks of most invasive histotypes among women with irregular cycles, but an increased risk of borderline serous and mucinous tumors ( P heterogeneity < 0.0001). Conclusions: Our results suggest that menstrual cycle characteristics influence ovarian cancer risk differentially based on histotype. Impact: These results highlight the importance of examining ovarian cancer risk factors associations by histologic subtype.

Background Dietary intake of lycopene has been associated with a reduced risk of ovarian cancer, suggesting its chemopreventive potential against ovarian carcinogenesis. Lycopene’s molecular mechanisms of action in ovarian cancer have not been fully understood. Therefore, in the present study, we investigated the effects of lycopene on the ovarian cancer formation using the laying hen model, a biologically relevant animal model of spontaneous ovarian carcinogenesis due to high incidence rates similar to humans. Methods In this study, a total of 150 laying hens at age of 102 weeks were randomized into groups of 50: a control group (0 mg of lycopene per kg of diet) and two treatment groups (200 mg or 400 mg of lycopene per kg of diet, or ~26 and 52 mg/d/hen, respectively). At the end of 12 months, blood, ovarian tissues and tumors were collected. Results We observed that lycopene supplementation significantly reduced the overall ovarian tumor incidence (P < 0.01) as well as the number and the size of the tumors (P < 0.004 and P < 0.005, respectively). Lycopene also significantly decreased the rate of adenocarcinoma, including serous and mucinous subtypes (P < 0.006). Moreover, we also found that the serum level of oxidative stress marker malondialdehyde was significantly lower in lycopene-fed hens compared to control birds (P < 0.001). Molecular analysis of the ovarian tumors revealed that lycopene reduced the expression of NF-κB while increasing the expression of nuclear factor erythroid 2 and its major target protein, heme oxygenase 1. In addition, lycopene supplementation decreased the expression of STAT3 by inducing the protein inhibitor of activated STAT3 expression in the ovarian tissues. Conclusions Taken together, our findings strongly support the potential of lycopene in the chemoprevention of ovarian cancer through antioxidant and anti-inflammatory mechanisms. PMID:29629346

What is the proper way of assessing the effect of progesterone elevation (PE) on the day of hCG on live birth in women undergoing fresh embryo transfer after in vitro fertilization (IVF) using GnRH analogues and gonadotrophins? This study indicates that a multivariable approach, where the effect of the most important confounders is controlled for, can lead to markedly different results regarding the association between PE on the day of hCG and live birth rates after IVF when compared with the bivariate analysis that has been typically used in the relevant literature up to date. PE on the day of hCG is associated with decreased pregnancy rates in fresh IVF cycles. Evidence for this comes from observational studies that mostly failed to control for potential confounders. This is a retrospective analysis of a cohort of fresh IVF/intracytoplasmic sperm injection cycles (n = 3296) performed in a single IVF centre during the period 2001-2013. Patients in whom ovarian stimulation was performed with gonadotrophins and GnRH analogues. Natural cycles and cycles where stimulation involved the administration of clomiphene were excluded. In order to reflect routine clinical practice, no other exclusion criteria were imposed on this dataset. The primary outcome measure for this study was live birth defined as the delivery of a live infant after 24 weeks of gestation. We compared the association between PE on the day of hCG (defined as P > 1.5 ng/ml) and live birth rates calculated by simple bivariate analyses with that derived from multivariable logistic regression. The multivariable analysis controlled for female age, number of oocytes retrieved, number of embryos transferred, developmental stage of embryos at transfer (cleavage versus blastocyst), whether at least one good-quality embryo was transferred, the woman's body mass index, the total dose of FSH administered during ovarian stimulation and the type of GnRH analogues used (agonists versus antagonists) during ovarian stimulation. In addition, an interaction analysis was performed in order to assess whether the ovarian response (<6, 6-18, >18 oocytes) has a moderating effect on the association of PE on the day of hCG with live birth rates after IVF. Live birth rates were not significantly different between cycles with and those without PE when a bivariate analysis was performed [odds ratio (OR): 0.78, 95% confidence interval (CI): 0.56-1.09]. However, when a multivariable analysis was performed, controlling for the effect of the aforementioned confounders, live birth rates (OR: 0.68, 95% CI: 0.48-0.97) were significantly decreased in the group with PE on the day of hCG. The number of oocytes retrieved was the most potent confounder, causing a 29.4% reduction in the OR for live birth between the two groups compared. Furthermore, a moderating effect of ovarian response on the association between PE and live birth rates was not supported in the present analysis since no interaction was detected between PE and the type of ovarian response (<6, 6-18, >18 oocytes). This is a retrospective analysis of data collected during a 12-year period, and although the effect of the most important confounders was controlled for in the multivariable analysis, the presence of residual bias cannot be excluded. This analysis highlights the need for a multivariable approach when researchers or clinicians aim to evaluate the impact of PE on pregnancy rates in their own clinical setting. Failure to do so might explain why many past studies have failed to identify the detrimental effect of PE in fresh IVF cycles. None. © The Author 2015.

We conducted a study to evaluate the changes in thyroid function during controlled ovarian hyperstimulation (COH) and its association with the outcome of assisted reproductive technique (ART). This is a prospective cohort study done in University Hospital Fertility Clinic for one year duration. A total of 88 euthyroid women who underwent COH as part of planned in-vitro fertilization (IVF) were invited to participate in this study. Serum thyroid function of each women will be monitored before stimulation (T1), day 10-13 of cycle (T2), during oocyte retrieval (T3), one week following embryo transfer (T4), and at four weeks after embryo transfer (T5). Reproductive outcome of IVF will be observed and documented. Nine women had ongoing singleton pregnancy, seven suffered from miscarriage, while the rest had implantation failure. Serum thyroid-stimulating hormone (TSH) and free thyroxine (fT4) increased throughout stimulation, peaking at 32-36 hours after hCG administration compared to baseline (1.250 vs. 1.740 mIU/L and 13.94 vs. 15.25 pmol/L). It remains elevated until one week following embryo transfer. The increment of serum TSH exceeded the upper limit, acceptable for first trimester (<1.60 mIU/L). However, the evolution of serum TSH and fT4 did not significantly differ with pregnancy outcome. In euthyroid women, thyroid function changed significantly during COH, but these changes were not different between the three reproductive outcomes. Thus, we do not suggest continuous thyroid function monitoring during COH.

Poor response to ovarian hyper-stimulation can be difficult to predict prior to stimulation even when factoring in patient age and ovarian reserve testing. When faced with the situation of poor response, patients and providers have the difficult decision to proceed with oocyte retrieval, convert to intrauterine insemination (IUI), or cancel the cycle. Although this is not an uncommon scenario, there is little data available to assist with the counseling of these patients. We performed a systematic review of published studies comparing clinical pregnancy and live births between those patients continuing with in-vitro fertilization (IVF) and those converting to IUI. PubMed and Ovid were searched for all retrospective and randomized studies using the Keywords 'in-vitro fertilization', 'intrauterine insemination', 'poor responders', 'clinical pregnancy' and 'live birth rates'. A total of seven retrospective studies and one randomized control trial were reviewed. When evaluating poor responders as a group, six studies reported higher overall clinical pregnancy rates and five studies reported overall increased live birth rates with continuance of IVF. When stratified by the number of follicles produced, continuance of IVF demonstrated higher clinical pregnancy and live birth rates with ≥ 2 follicles. When only one follicle developed there were no significant differences in clinical pregnancy or live birth rates between the two groups. In patients undergoing IVF with ≤4 follicles, continuance with IVF may lead to higher clinical pregnancy and live birth compared to conversion to IUI except in patients with monofollicular development, although additional randomized controlled trials are needed to confirm these findings.

To evaluate the impact on ovarian reserve between two different methods ofhemostasis after laparoscopic ovarian endometrioma excision. A randomized controlled study was conducted from January to December 2013 in Thammasat University Hospital, Thailand. Reproductive women, age 18-45years who underwent laparoscopic ovarian cystectomy were randomized in electrocoagulation and suture groups. Clinical baseline data and ovarian reserve outcome (anti-Mullerian hormone (AMH)) were evaluated. Fifty participants were recruited and randomized in two groups. Electrocoagulation and suture groups consisted of 25 participants. Baseline characteristics between 2 groups (age, weight, BMI, height, cyst diameter, duration and estimated blood loss) were not statistically different. There were no significant difference of AMIH between electrocoagulation and suture group atpre-operative (2.90±2.26 vs. 2.52±2.37 ng/ml), 1 week (1.78±1.51 vs. 1.99±1.71 ng/ml), 1 month (1.76±1.50 vs. 2.09±1.62 ng/ml), 3 months (2.09±1.66 vs. 1.96±1.68 ng/ml) and 6 months (2.11±1.84 vs 1.72±1.68 ng/ml), respectively. However mean AMH ofboth groups significantly decreased since the first week of operation. Effect oflaparoscopic ovarian surgery had significantly declined and sustained AMH level until 6 months. Laparoscopic cystectomy of ovarian endometrioma has negative impact to ovarian reserve. Either electroco- agulation or suture method had no different effects.

A considerable proportion of all women undergoing IVFrespond poorly to gonadotropin stimulation. These women are reported to be associated with increased cancellation rates and lower pregnancy rates. It has been hypothesized that poor response to ovarian stimulation is a first sign of ovarian ageing or premature ovarian failure, which might be related to altered inflammatory response in the body. We aimed to compare follicular fluid presepsin levels between poor- and normo-responder patients to ovarian stimulation, to assess its relationship with reproductive outcomes. This study included infertility patients who underwent ovulation induction with either long GnRH agonist or GnRH antagonist protocols and who subsequently underwent IVF/ICSI. Included patients were assigned to two groups according to the Bologna criteria for poor ovarian response. Group 1 and 2 consisted of normo- and poor-responder patients, respectively.The 2 groups were compared in terms of FF presepsin levels. Also, any relationship between the FF presepsin levels and fertility outcomes was assessed within the groups. The groups were compared by using student’s t-test, Mann-Whitney U test and X2 test, where appropriate. Pregnancy rates were not significantly different between the groups (22.6% and 17.6%; P=0.650, respectively). FF presepsin levels were higher in Group 1, however, the difference was not statistically significant (298.0±797.4 and 149.2±422.3; P=0.190, respectively). FF presepsin levels did not significantly differ between pregnancy positive and the pregnancy negative patients in both Group 1 (243.6±531.1 and 314.3±866.5; P=0.055, respectively) and Group 2 (112.2±79.8 and 157.1±464.3; P=0.394, respectively). Consequently, FF presepsin seems not to be a reliable marker in predicting pregnancy in both normo-responder and poor-responder infertility groups. PMID:26309683

The objective of this study is to explore the effects of amygdala kindling on estrus cycle and ovarian morphology. Thirty-five female rats at the age of 8 weeks were randomly designated to electrode kindled, sham-kindled, and normal controls. Kindled rats were implanted with kindling electrodes in the left basolateral amygdala and kindled by brief suprathreshold stimulations with a bipolar electrode. Estrous cycles were daily monitored through vaginal smears. Electrographic and behavioral seizures were recorded and ovarian morphology was evaluated by light and electron microscopies. Our results showed that the kindled rats lost their ovarian periodicity displayed significant ovarian enlargement. H&E staining revealed increased number of growing follicles and total follicles, as well as polycysts in the ovaries of the kindled animals compared to sham and control animals. Ultrastructural study detected numerous apoptotic granulosa cells in growing follicles and thecal cell hyperplasia with secretary granules in the thecal cells in the kindled rats. The results suggest that amygdala kindling is a risk factor for the development of polycystic ovary syndrome.

Epithelial ovarian cancer is the leading cause of death from gynaecologic cancers in the Western world. If possible, initial cytoreductive surgery is the treatment of choice, followed by adjuvant chemotherapy, usually with a platinum/taxane combination. Increased survival has been recently reported in women who were given adjuvant chemotherapy weekly rather than at three-week intervals, which has been the standard. At our centre, we have been treating patients with advanced ovarian cancer with a dose-dense protocol since March 2010. Treatment is given in an outpatient setting on days 1, 8, and 15 of a 21-day cycle for six cycles. Carboplatin for an AUC of 5 mg/mL/min and paclitaxel 80mg/m² are given on day 1, followed by paclitaxel 80mg/m² on days 8 and 15. Our objective was to determine whether this protocol is a feasible alternative treatment in our population and whether or not the toxicity profile is acceptable. We performed a chart review of 46 patients undergoing treatment with dose-dense chemotherapy for advanced ovarian cancer. Demographic information, patient characteristics, adverse events, and treatment endpoints were recorded. Sixty-one percent of women completed the six-cycle protocol as planned with minimal interruption, which is comparable to the only previously reported trial using this regimen. The most common side effects of treatment were fatigue, neuropathy, and neutropenia. Supplementation with regular magnesium and granulocyte colony-stimulating factor reduced delays. Dose-dense paclitaxel with carboplatin chemotherapy for the treatment of advanced ovarian cancer shows promise in terms of progression-free and overall survival. We have shown this protocol to be practical and feasible in our population.

HER2-targeted therapy has been shown to have limited efficacy in ovarian cancer despite frequent overexpression of this receptor. Photochemical internalization (PCI) is a modality for cytosolic drug delivery, currently undergoing clinical evaluation. In the present project we studied the application of PCI in combination with the HER2-targeted recombinant fusion toxin, MH3-B1/rGel, for the treatment of ovarian cancer. The SKOV-3 cell line, resistant to trastuzumab- and MH3-B1/rGel- monotherapy, was shown to respond strongly to PCI of MH3-B1/rGel to a similar extent as observed for the treatment-sensitive SK-BR-3 breast cancer cells. Extensive hydrolytic degradation of MH3-B1/rGel in acidic endocytic vesicles was indicated as the mechanism of MH3-B1/rGel resistance in SKOV-3 cells. This was shown by the positive Pearson's correlation coefficient between Alexa488-labeled MH3-B1/rGel and Lysotracker in SKOV-3 cells in contrast to the negative Pearson's correlation coefficient in SK-BR-3 cells. The application of PCI to induce the release of MH3-B1/rGel was also demonstrated to be effective on SKOV-3 xenografts. Application of PCI with MH3-B1/rGel was further found highly effective in the HER2 expressing HOC-7 and NuTu-19 ovarian cancer cell lines. The presented results warrant future development of PCI in combination with MH3-B1/rGel as a novel therapeutic approach in preclinical models of ovarian cancer. PMID:26002552

Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy. Blood samples were taken at three time points: Before, four weeks after and two years after adjuvant chemotherapy. Serum AMH-levels were evaluated in a central laboratory by a quantitative immunoassay AMH Gen II ELISA (Beckman Coulter, Brea, USA). Median age was 36 years (21-40 years). Median serum AMH-level before chemotherapy was 1.37 ng/ml (range < 0.1-11.3 ng/ml). Four weeks after chemotherapy AMH-levels dropped in 98.6% of the patients to <0.1 ng/ml (range < 0.1-0.21 ng/ml). After two years, 73.3% (n = 101) showed no evidence of ovarian function recovery (AMH <0.1 ng/ml, range < 0.1-3.9 ng/ml). Permanent chemotherapy induced amenorrhea occurred only in 50.6% of the patients. In this analysis, premenopausal patients showed a high rate of ovarian impairment reflected by low AMH-levels after chemotherapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose: Ovarian cancer is the leading cause of death from gynecologic malignancy in the United States, with high rates of recurrence and eventual resistance to cytotoxic chemotherapy. Model systems that allow for accurate and reproducible target discovery and validation are needed to support further drug development in this disease. Experimental Design: Clinically annotated patient-derived xenograft (PDX) models were generated from tumor cells isolated from the ascites or pleural fluid of patients undergoing clinical procedures. Models were characterized by IHC and by molecular analyses. Each PDX was luciferized to allow for reproducible in vivo assessment of intraperitoneal tumor burden by bioluminescence imaging (BLI). Plasma assays for CA125 and human LINE-1 were developed as secondary tests of in vivo disease burden. Results: Fourteen clinically annotated and molecularly characterized luciferized ovarian PDX models were generated. Luciferized PDX models retain fidelity to both the nonluciferized PDX and the original patient tumor, as demonstrated by IHC, array CGH, and targeted and whole-exome sequencing analyses. Models demonstrated diversity in specific genetic alterations and activation of PI3K signaling pathway members. Response of luciferized PDX models to standard-of-care therapy could be reproducibly monitored by BLI or plasma markers. Conclusions: We describe the establishment of a collection of 14 clinically annotated and molecularly characterized luciferized ovarian PDX models in which orthotopic tumor burden in the intraperitoneal space can be followed by standard and reproducible methods. This collection is well suited as a platform for proof-of-concept efficacy and biomarker studies and for validation of novel therapeutic strategies in ovarian cancer.

To determine normal ranges for serum anti-Mullerian hormone (AMH) using the new automated Elecsys AMH assay platform, with a view to establishing values that signify premature loss of ovarian reserve, increased risk for an excessive response during IVF stimulation and a likely diagnosis of polycystic ovary syndrome (PCOS). Serum AMH was measured by the Elecsys automated electrochemiluminescence assay in 654 women undergoing gynaecological assessment. Serum AMH levels peaked before 25 years of age, with mean AMH levels halving by 36 and falling to a quarter of their peak by 40 years of age. Overall, AMH results of 95% of patients with PCOS exceeded the 50th percentile for their age, with 72.1% having an AMH result in the top quartile for age. ROC analysis suggested that a serum AMH ≥36 pmol L(-1) is the best determinant of PCOS status (sensitivity 83.7% and specificity 82.3%). Serum AMH exhibited an excellent correlation with ultrasound-assessed antral follicle count (AFC) (r = 0.836, P < 0.0001), with a result of 20 pmol L(-1) corresponding to an AFC of 16 and, therefore, increased risk of ovarian hyperstimulation syndrome (OHSS) during IVF treatment. Serum AMH is a sensitive marker of age-related decline in ovarian reserve status. A serum AMH result >36 pmol L(-1) , or above the 75th percentile for age, is highly suggestive of a diagnosis of PCOS. A serum AMH result below the 10th percentile for age suggests accelerated loss of ovarian reserve, while an AMH result exceeding 20 pmol L(-1) suggests an increased risk of OHSS during IVF treatment. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Genetic testing of cancer predisposing genes will increasingly be needed in oncology clinics to target cancer treatment. This Delphi study aimed to identify areas of agreement and disagreement between genetics and oncology health professionals and service users about the key messages required by women with breast/ovarian cancer who undergo BRCA1/BRCA2 genetic testing and the optimal timing of communicating key messages. Participants were 16 expert health professionals specialising in oncology/genetics and 16 service users with breast/ovarian cancer and a pathogenic BRCA1/BRCA2 variant. Online questionnaires containing 53 inductively developed information messages were circulated to the groups separately. Participants rated each message as key/not key on a Likert scale and suggested additional messages. Questionnaires were modified according to the feedback and up to 3 rounds were circulated. Consensus was reached when there was ≥75% agreement. Thirty key messages were agreed by both groups with 7 of the key messages agreed by ≥95% of participants: dominant inheritance, the availability of predictive testing, the importance of pretest discussion, increased risk of breast and ovarian cancer, and the option of risk-reducing mastectomy and bilateral salpingo-oophorectomy. Both groups agreed that key messages should be communicated before genetic testing and once a pathogenic variant has been identified. There was a high level of agreement within and between the groups about the information requirements of women with breast/ovarian cancer about BRCA1/BRCA2. These key messages will be helpful in developing new approaches to the delivery of information as genetic testing becomes further integrated into mainstream oncology services.

Ovarian cancer is the deadliest gynecologic cancer in the US. The consumption of refined sugars has increased dramatically over the past few decades, accounting for almost 15% of total energy intake. Yet, there is limited evidence on how sugar consumption affects ovarian cancer risk. We evaluated ovarian cancer risk in relation to sugary foods and beverages, and total and added sugar intakes in a population-based case-control study. Cases were women with newly diagnosed epithelial ovarian cancer, older than 21 years, able to speak English or Spanish, and residents of six counties in New Jersey. Controls met same criteria as cases, but were ineligible if they had both ovaries removed. A total of 205 cases and 390 controls completed a phone interview, food frequency questionnaire, and self-recorded waist and hip measurements. Based on dietary data, we computed the number of servings of dessert foods, non-dessert foods, sugary drinks and total sugary foods and drinks for each participant. Total and added sugar intakes (grams/day) were also calculated. Multiple logistic regression models were used to estimate odds ratios and 95% confidence intervals for food and drink groups and total and added sugar intakes, while adjusting for major risk factors. We did not find evidence of an association between consumption of sugary foods and beverages and risk, although there was a suggestion of increased risk associated with sugary drink intake (servings per 1,000 kcal; OR=1.63, 95% CI: 0.94-2.83). Overall, we found little indication that sugar intake played a major role on ovarian cancer development.

To observe the effects of autologous blood injection and 0.9% NaCl at Zusanli (ST 36) on ovarian function in patients with primary ovarian insufficiency. Sixty patients with primary ovarian insufficiency were randomly divided into an observation group and a control group, 30 cases in each one. The patients in the observation group were treated with injection of autologous blood at Zusanli (ST 36); the patients in the control group were treated with 0.9% NaCl with identical volume at Zusanli (ST 36). Both the treatments were given once a week for 3 months. The ovarian function, including follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E 2 ) were tested before treatment, 1 month, 2 months and 3 months after first acupoint injection; the endometrial thickness before and after treatment and clinical efficacy were compared in the two groups. Compared before treatment, FSH was lowered in the observation group after 1-month treatment ( P <0.05), while FSH and LH were lowered and E 2 was increased after 2-month treatment and 3-month treatment (all P <0.05). Compared with 1-month treatment, FSH and LH were lowered and E 2 was increased in the observation group after 2-month treatment and 3-month treatment (all P <0.05). Compared with 2-month treatment, FSH was lowered and E 2 was increased in the observation group after 3-month treatment (both P <0.05). The differences of all serum tests before and after treatment were insignificant in the control group (all P >0.05). The FSH after 1-month treatment, and FSH, LH and E 2 after 2-month treatment and 3-month treatment in the observation group were significantly different from those in the control group (all P <0.05). The endometrial thickness after treatment in the observation group was higher than that before treatment ( P <0.05), while the endometrial thickness after treatment in the control group was similar to that before treatment ( P >0.05); the difference of endometrial thickness before and after treatment in the observation group was higher than that in the control group ( P <0.05). The clinical effective rate was 83.3% (25/30) in the observation group, which was superior to 46.7% (14/30) in the control group ( P <0.05). The autologous blood injection at Zusanli (ST 36) can significantly improve ovarian function, promote endometrial growth in patients with primary ovarian insufficiency.

Is ceramide-1-phosphate (C1P) an ovarian protective agent during alkylating chemotherapy? Local administration of C1P drastically reduces ovarian damage induced by cyclophosphamide (Cy) via protection of follicular reserve, restoration of hormone levels, inhibition of apoptosis and improvement of stromal vasculature, while protecting fertility, oocyte quality and uterine morphology. Cancer-directed therapies cause accelerated loss of ovarian reserve and lead to premature ovarian failure (POF). Previous studies have demonstrated that C1P regulates different cellular processes including cell proliferation, cell migration, angiogenesis and apoptosis. This sphingolipid may be capable of modulating vascular development and apoptosis in ovaries affected by chemotherapy. The 6-8-week-old mice were weighed and administered either a single intraperitoneal injection of Cy (75 mg/kg) or an equal volume of saline solution only for control mice. Control and Cy mice underwent sham surgery and received an intrabursal injection of saline solution, while Cy + C1P animal groups received 5 μl C1P, either 0.5 or 1 mM, under the bursa of both ovaries 1 h prior to Cy administration. Animals were euthanized by cervical dislocation or cardiac puncture 2 weeks after surgery for collection of blood orovary and uterus samples, which were cleaned of adhering tissue in culture medium and used for subsequent assays. Ovaries were used for Western blotting or immunohistochemical and/or histological analyses or steroid extraction, as required (n = 5-8 per group). A set of mice (n = 3/group) was destined for oocyte recovery and IVF. Finally, another set (n = 5-6/group) was separated to study fertility parameters. The number of primordial (P < 0.01), primary (P < 0.05) and preantral follicles (P < 0.05) were decreased in Cy-treated mice compared to control animals, while atretic follicles were increased (P < 0.001). In Cy + C1P mice, the ovaries recovered control numbers of these follicular structures, in both C1P doses studied. Cy affected AMH expression, while it was at least partially recovered when C1P is administered as well. Cy caused an increase in serum FSH concentration (P < 0.01), which was prevented by C1P coadministration (P < 0.01). E2 levels in Cy-treated ovaries decreased significantly compared to control ovaries (P < 0.01), whilst C1P restored E2 levels to those of control ovaries (P < 0.01). Cy increased the expression of BAX (P < 0.01) and decreased the expression of BCLX-L compared to control ovaries (P < 0.01). The ovarian BCLX-L:BAX ratio was also lower in Cy-treated mice (P < 0.05). In the Cy + C1P group, the expression levels of BAX, BCLX-L and BCLX-L:BAX ratio were no different than those in control ovaries. In addition, acid sphingomyelinase (A-SMase) expression was higher in Cy-treated ovaries, whilst remaining similar to the control in the Cy + C1P group. Cy increased the apoptotic index (TUNEL-positive follicles/total follicles) in preantral and early antral stages, compared to control ovaries (P < 0.001 and P < 0.01, respectively). C1P protected follicles from this increase. No primordial or primary follicular cells stained for either cleaved caspase-3 or TUNEL when exposed to Cy, therefore, we have found no evidence for follicular reserve depletion in response to Cy being due to apoptosis. Cy caused evident vascular injury, especially in large cortical stromal vessels, and some neovascularization. In the Cy + C1P group, the disruptions in vascular wall continuity were less evident and the number of healthy stromal blood vessels seemed to be restored. In Cy-treated ovaries α-SMA-positive cells showed a less uniform distribution around blood vessels. C1P coadministration partially prevented this Cy-induced effect, with a higher presence of α-SMA-positive cells surrounding vessels. By H&E staining, Cy-treated mice showed endometrial alterations compared to controls, affecting both epithelial and stromal compartments. However, C1P allowed that the stromal tissue to maintain its loose quality and its glandular branches. Cy-treated animals had significantly lower pregnancy rates and smaller litter sizes compared with control mice (P = 0.013 and P < 0.05, respectively), whereas cotreatment with C1P preserved normal fertility. Furthermore, a higher (P < 0.05) proportion of abnormal oocytes was recovered from Cy-treated mice compared to the control, which was prevented by C1P administration. N/A. The results of this study were generated from an in-vivo animal experimental model, already used by several authors. Further studies on C1P functions in female reproduction in pathological conditions such as chemotherapy-induced ovarian failure and on the safety of use of this sphingolipid are required. The present findings showed that C1P administration prior to Cy might be a promising fertility preservation strategy in female patients who undergo chemotherapy.

The FANCA gene is one of the genes in which mutations lead to Fanconi anaemia, a rare autosomal recessive disorder characterised by congenital abnormalities, bone marrow failure, and predisposition to malignancy. FANCA is also a potential breast and ovarian cancer susceptibility gene. A novel allele was identified which has a tandem duplication of a 13 base pair sequence in the promoter region. We screened germline DNA from 352 breast cancer patients, 390 ovarian cancer patients and 256 normal controls to determine if the presence of either of these two alleles was associated with an increased risk of breast or ovarian cancer. The duplication allele had a frequency of 0.34 in the normal controls. There was a non-significant decrease in the frequency of the duplication allele in breast cancer patients. The frequency of the duplication allele was significantly decreased in ovarian cancer patients. However, when malignant and benign tumours were considered separately, the decrease was only significant in benign tumours. The allele with the tandem duplication does not appear to modify breast cancer risk but may act as a low penetrance protective allele for ovarian cancer.

The opportunity to use gonadotropins to stimulate the growth of antral follicles coming from different follicular waves available in different moment of the menstrual cycle allowed the implementation of innovative protocols in assisted reproductive technologies. The purpose of this review is to explore the possible advantages related to these new controlled ovarian stimulation (COS) strategies. Women exhibit major and minor wave patterns of ovarian follicular development during the menstrual cycle, as it is in animal species. These observations led to the introduction of two new strategies for COS: the random start and the double ovarian stimulation within a single menstrual cycle. The use of gonadotropin-releasing hormone antagonist COS protocols, started randomly at any day of the menstrual cycle, is today a standard procedure in those cases where obtaining oocytes is an urgent task, such as in case of fertility preservation for malignant diseases or other medical indications.On the other hand, in poor prognosis patients, double ovarian stimulation has been suggested with the aim of maximizing the number of oocytes retrieved within a single menstrual cycle and, in turn increasing the chance to obtain a reproductively competent embryo. Randomized control trials are necessary to confirm these preliminary findings.

Lysophosphatidic Acid Initiates Epithelial to Mesenchymal Transition and Induces β-Catenin-mediated Transcription in Epithelial Ovarian Carcinoma*

During tumor progression, epithelial ovarian cancer (EOC) cells undergo epithelial-to-mesenchymal transition (EMT), which influences metastatic success. Mutation-dependent activation of Wnt/β-catenin signaling has been implicated in gain of mesenchymal phenotype and loss of differentiation in several solid tumors; however, similar mutations are rare in most EOC histotypes. Nevertheless, evidence for activated Wnt/β-catenin signaling in EOC has been reported, and immunohistochemical analysis of human EOC tumors demonstrates nuclear staining in all histotypes. This study addresses the hypothesis that the bioactive lipid lysophosphatidic acid (LPA), prevalent in the EOC microenvironment, functions to regulate EMT in EOC. Our results demonstrate that LPA induces loss of junctional β-catenin, stimulates clustering of β1 integrins, and enhances the conformationally active population of surface β1 integrins. Furthermore, LPA treatment initiates nuclear translocation of β-catenin and transcriptional activation of Wnt/β-catenin target genes resulting in gain of mesenchymal marker expression. Together these data suggest that LPA initiates EMT in ovarian tumors through β1-integrin-dependent activation of Wnt/β-catenin signaling, providing a novel mechanism for mutation-independent activation of this pathway in EOC progression.

The majority of high-grade serous ovarian cancers is now believed to originate in the fallopian tubes. Therefore, current practices include the pathological examination of excised fallopian tubes. Detection of tumors in the fallopian tubes using current clinical approaches remains difficult but is of critical importance to achieve accurate staging and diagnosis. Here, we present an intraoperative imaging system for the detection of human fallopian tube lesions. The system is based on optical coherence tomography (OCT) to access subepithelial tissue architecture. To demonstrate that OCT could identify lesions, we analyzed 180 OCT volumes taken from five different ovarian lesions and from healthy fallopian tubes, and compared them to standard pathological review. We demonstrated that qualitative features could be matched to pathological conditions. We then determined the feasibility of intraluminal imaging of intact human fallopian tubes by building a dedicated endoscopic single-fiber OCT probe to access the mucosal layer inside freshly excised specimens from five patients undergoing prophylactic surgeries. The probe insertion into the lumen acquired images over the entire length of the tubes without damaging the mucosa, providing the first OCT images of intact human fallopian tubes.

Advanced reproductive age and fertility.

To improve awareness of the natural age-related decline in female and male fertility with respect to natural fertility and assisted reproductive technologies (ART) and provide recommendations for their management, and to review investigations in the assessment of ovarian aging. This guideline reviews options for the assessment of ovarian reserve and fertility treatments using ART with women of advanced reproductive age presenting with infertility. The outcomes measured are the predictive value of ovarian reserve testing and pregnancy rates with natural and assisted fertility. Published literature was retrieved through searches of PubMed or Medline, CINAHL, and The Cochrane Library in June 2010, using appropriate key words (ovarian aging, ovarian reserve, advanced maternal age, advanced paternal age, ART). Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated into the guideline to December 2010. The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care. Recommendations for practice were ranked according to the method described in that report (Table). Primary and specialist health care providers and women will be better informed about ovarian aging and the age-related decline in natural fertility and about options for assisted reproductive technology. 1. Women in their 20s and 30s should be counselled about the age-related risk of infertility when other reproductive health issues, such as sexual health or contraception, are addressed as part of their primary well-woman care. Reproductive-age women should be aware that natural fertility and assisted reproductive technology success (except with egg donation) is significantly lower for women in their late 30s and 40s. (II-2A) 2. Because of the decline in fertility and the increased time to conception that occurs after the age of 35, women > 35 years of age should be referred for infertility work-up after 6 months of trying to conceive. (III-B) 3. Ovarian reserve testing may be considered for women ≥ 35 years of age or for women < 35 years of age with risk factors for decreased ovarian reserve, such as a single ovary, previous ovarian surgery, poor response to follicle-stimulating hormone, previous exposure to chemotherapy or radiation, or unexplained infertility. (III-B) 4. Ovarian reserve testing prior to assisted reproductive technology treatment may be used for counselling but has a poor predictive value for non-pregnancy and should be used to exclude women from treatment only if levels are significantly abnormal. (II-2A) 5. Pregnancy rates for controlled ovarian hyperstimulation are low for women > 40 years of age. Women > 40 years should consider IVF if they do not conceive within 1 to 2 cycles of controlled ovarian hyperstimulation. (II-2B) 6. The only effective treatment for ovarian aging is oocyte donation. A woman with decreased ovarian reserve should be offered oocyte donation as an option, as pregnancy rates associated with this treatment are significantly higher than those associated with controlled ovarian hyperstimulation or in vitro fertilization with a woman's own eggs. (II-2B) 7. Women should be informed that the risk of spontaneous pregnancy loss and chromosomal abnormalities increases with age. Women should be counselled about and offered appropriate prenatal screening once pregnancy is established. (II-2A) 8. Pre-conception counselling regarding the risks of pregnancy with advanced maternal age, promotion of optimal health and weight, and screening for concurrent medical conditions such as hypertension and diabetes should be considered for women > age 40. (III-B) 9. Advanced paternal age appears to be associated with an increased risk of spontaneous abortion and increased frequency of some autosomal dominant conditions, autism spectrum disorders, and schizophrenia. Men > age 40 and their partners should be counselled about these potential risks when they are seeking pregnancy, although the risks remain small. (II-2C).

Human umbilical cord mesenchymal stem cells (hUCMSCs) are a type of pluripotent stem cell which are isolated from the umbilical cord of newborns. hUCMSCs have great therapeutic potential. We designed this experimental study in order to investigate whether the transplantation of hUCMSCs can improve the ovarian reserve function of perimenopausal rats and delay ovarian senescence. We selected naturally aging rats confirmed by vaginal smears as models of perimenopausal rats, divided into the control group and the treatment group, and selected young fertile female rats as normal controls. hUCMSCs were transplanted into rats of the treatment group through tail veins. Enzyme-linked immunosorbent assay (ELISA) detected serum levels of sex hormones, H&E staining showed ovarian tissue structure and allowed follicle counting, immunohistochemistry and western blot analysis revealed ovarian expression of hepatocyte growth factor (HGF), vascular endothelial cell growth factor (VEGF), and insulin-like growth factor-1 (IGF-1), polymerase chain reaction (PCR) and western blot analysis revealed hUCMSCs expression of HGF, VEGF, and IGF-1. At time points of 14, 21, and 28 days after hUCMSCs transplantation, estradiol (E 2 ) and anti-Müllerian hormone (AMH) increased while follicle-stimulating hormone (FSH) decreased; ovarian structure improved and follicle number increased; ovarian expression of HGF, VEGF, and IGF-1 protein elevated significantly. Meanwhile, PCR and western blot analysis indicated hUCMSCs have the capacity of secreting HGF, VEGF, and IGF-1 cytokines. Our results suggest that hUCMSCs can promote ovarian expression of HGF, VEGF, and IGF-1 through secreting those cytokines, resulting in improving ovarian reserve function and withstanding ovarian senescence.

Cancer stem cells are a small subset of cancer cells that contribute to cancer progression, metastasis, chemoresistance and recurrence. CD133-positive (CD133+) ovarian cancer cells have been identified as ovarian cancer stem cells. Adenovirus-mediated gene therapy is an innovative therapeutic method for cancer treatment. In the present study, we aimed to develop a new gene therapy to specifically eliminate CD133+ ovarian cancer stem cells by targeting CD133. We used the Cre/LoxP system to augment the selective expression of the truncated Bid (tBid) gene as suicide gene therapy in CD133+ ovarian cancer stem cells. The adenovirus (Ad)-CD133-Cre expressing Cre recombinase under the control of the CD133 promoter and Ad-CMV-LoxP-Neo-LoxP-tBid expressing tBid under the control of the CMV promoter were successfully constructed using the Cre/LoxP switching system. The co-infection of Ad-CMV-LoxP-Neo-LoxP-tBid and Ad-CD133-Cre selectively induced tBid overexpression, which inhibited cell growth and triggered the cell apoptosis of CD133+ ovarian cancer stem cells. The Cre/LoxP system-mediated tBid overexpression activated the pro-apoptotic signaling pathway and augmented the cytotoxic effect of cisplatin in CD133+ ovarian cancer stem cells. Furthermore, in xenograft experiments, co-infection with the two recombinant adenoviruses markedly suppressed tumor growth in vivo and promoted cell apoptosis in tumor tissues. Taken together, the present study provides evidence that the adenovirus-mediated tBid overexpression induced by the Cre/LoxP system can effectively eliminate CD133+ ovarian cancer stem cells, representing a novel therapeutic strategy for the treatment of ovarian cancer.

Differential flatness properties and multivariable adaptive control of ovarian system dynamics

NASA Astrophysics Data System (ADS)

The ovarian system exhibits nonlinear dynamics which is modeled by a set of coupled nonlinear differential equations. The paper proposes adaptive fuzzy control based on differential flatness theory for the complex dynamics of the ovarian system. It is proven that the dynamic model of the ovarian system, having as state variables the LH and the FSH hormones and their derivatives, is a differentially flat one. This means that all its state variables and its control inputs can be described as differential functions of the flat output. By exploiting differential flatness properties the system's dynamic model is written in the multivariable linear canonical (Brunovsky) form, for which the design of a state feedback controller becomes possible. After this transformation, the new control inputs of the system contain unknown nonlinear parts, which are identified with the use of neurofuzzy approximators. The learning procedure for these estimators is determined by the requirement the first derivative of the closed-loop's Lyapunov function to be a negative one. Moreover, Lyapunov stability analysis shows that H-infinity tracking performance is succeeded for the feedback control loop and this assures improved robustness to the aforementioned model uncertainty as well as to external perturbations. The efficiency of the proposed adaptive fuzzy control scheme is confirmed through simulation experiments.

ATAD5/ELG1 is a protein crucially involved in replication and maintenance of genome stability. ATAD5 has recently been identified as a genomic risk locus for both breast and ovarian cancer through genome-wide association studies. We aimed to investigate the spectrum of coding ATAD5 germ-line mutations in hospital-based series of patients with triple-negative breast cancer or serous ovarian cancer compared with healthy controls. The ATAD5 coding and adjacent splice site regions were analyzed by targeted next-generation sequencing of DNA samples from 273 cancer patients, including 114 patients with triple-negative breast cancer and 159 patients with serous epithelial ovarian cancer, and from 276 healthy females. Among 42 different variants identified, twenty-two were rare missense substitutions, of which 14 were classified as pathogenic by at least one in silico prediction tool. Three of four novel missense substitutions (p.S354I, p.H974R and p.K1466N) were predicted to be pathogenic and were all identified in ovarian cancer patients. Overall, rare missense variants with predicted pathogenicity tended to be enriched in ovarian cancer patients (14/159) versus controls (11/276) (p = 0.05, 2df). While truncating germ-line variants in ATAD5 were not detected, it remains possible that several rare missense variants contribute to genetic susceptibility toward epithelial ovarian carcinomas.

The platelet-to-lymphocyte ratio (PLR) is a predictive clinical biomarker for different cancers. However, the results of several studies investigating the association between the PLR and the prognosis of ovarian cancer have been inconclusive. Therefore, there is a need to conduct a meta-analysis to estimate the prognostic value of the PLR in ovarian cancer. We searched the EMBASE, Medline, PubMed, and Web of Science databases to identify clinical studies that had evaluated the association between the PLR and ovarian cancer prognosis. Outcomes evaluated included overall survival (OS) and progression-free survival (PFS). We also analyzed PLR differences between malignant ovarian masses and the controls. Twelve relevant studies that comprised 2340 patients were selected for the meta-analysis. The results revealed that elevated PLR was significantly associated with poor OS (hazard ratio (HR) 1.63, 95% confidence interval (CI) 1.05-2.56, p < 0.01) and PFS (HR 1.61, 95% CI 1.03-2.51, p < 0.01). The PLRs in malignant cases were higher than in controls (mean difference = 63.57, 95% CI 39.47-87.66, p < 0.00001). An elevated PLR is associated with poor prognosis in patients with ovarian cancer. The PLR could be employed as a prognostic marker in patients with ovarian cancer.

Ovarian cancer is the fifth leading cause of cancer-related deaths among women, primarily due to diagnosis at late stages. Therefore, identification of modifiable risk factors for this disease is warranted. Using the Patient Epidemiology Data System (PEDS), collected from 1981 to 1998 at Roswell Park Cancer Institute, Buffalo, NY, we conducted a hospital-based, case-control analysis of self-reported cruciferous vegetable intake and ovarian cancer among 675 women with primary, incident ovarian cancer, and 1275 without cancer. Cruciferous vegetable intake was queried using a 44-item food frequency questionnaire (FFQ). Odds ratios (OR) and 95% confidence intervals (CI) were estimated with logistic regression, adjusting for age, body mass index (BMI), education, smoking status, parity, family history of ovarian cancer, total fruit consumption, total meat consumption, and total noncruciferous vegetable consumption. We observed a significant inverse association for women with highest vs. lowest intakes of total vegetables (OR = 0.65, 95% CI = 0.46-0.92), cooked cauliflower (OR = 0.82, 95% CI = 0.67-0.99), and cooked greens (OR = 0.63, 95% CI = 0.46-0.86) and an inverse, dose-dependent association between cooked cruciferous vegetables intake and ovarian cancer (for each additional ten servings per month, OR = 0.85, 95% CI = 0.76-0.96). These findings suggest that a diet that includes cruciferous vegetables could be an important modifiable risk factor for ovarian cancer.

This study was intended to assess the effects of oral contraceptives given before treatment in infertile anovulatory patients with polycystic ovary syndrome who receive gonadotropins for controlled ovarian stimulation. Pretreatment with oral contraceptives increased the mono-ovulatory cycles, the duration of stimulation for noncanceled cycles, and the number of vials of gonadotropins used. It also reduced the number of dominant follicles and the peak E(2) levels for dominant follicles. No effect was observed in rates of cycle cancellation, pregnancy, abortion, live birth, multiple pregnancies, and ovarian hyperstimulation syndrome.

Can Sphingosine-1-phosphate (S1P), a ceramide-induced death pathway inhibitor, prevent cyclophosphamide (Cy) or doxorubicin (Doxo) induced apoptotic follicle death in human ovarian xenografts? S1P can block human apoptotic follicle death induced by both drugs, which have differing mechanisms of cytotoxicity. S1P has been shown to decrease the impact of chemotherapy and radiation on germinal vesicle oocytes in animal studies but no human translational data exist. Experimental human ovarian xenografting to test the in vivo protective effect of S1P on primordial follicle survival in the chemotherapy setting. The data were validated by assessing the same protective effect in the ovaries of xenografted mice in parallel. Xenografted mice were treated with Cy (75 mg/kg), Cy+S1P (200 μM), Doxo (10 mg/kg), Doxo+S1P or vehicle only (Control). S1P was administered via continuous infusion using a mini-osmotic pump beginning 24 h prior to and ending 72 h post-chemotherapy. Grafts were then recovered and stained with anti-caspase 3 antibody for the detection of apoptosis in primordial follicles. The percentage of apoptotic to total primordial follicles was calculated in each group. Both Cy and Doxo resulted in a significant increase in apoptotic follicle death in human ovarian xenografts compared with controls (62.0 ± 3.9% versus 25.7 ± 7.4%, P < 0.01 and 76.7 ± 7.4% versus 25.7 ± 7.4%, P < 0.01, respectively). This chemotherapy-induced apoptotic death was reduced both in the Cy+S1P (32.7 ± 4.4%, P < 0.01) and the Doxo+S1P group (27.1 ± 7.6%, P < 0.01) compared with Cy and Doxo groups, respectively. In the Doxo+S1P and Cy+S1P groups, the percentages of apoptotic follicles were similar to those of vehicle-treated controls (P > 0.05). The findings from the ovaries of the severe combined immunodeficient mice mirrored the findings with human tissue. The functionality of the rescued human ovarian follicles needs to be evaluated in future studies though the studies in rodents showed that rescued oocytes can result in healthy offspring. In addition, the impact of S1P on cancer cells should be further studied. S1P and its future analogs hold promise for preserving fertility by pharmacological means for patients undergoing chemotherapy.

The present study investigated whether dietary turmeric (Curcuma longa L.) can improve rabbit reproduction, ovarian function, growth, or viability. Female New Zealand White rabbits were either fed a standard diet (n=15) or a diet enriched with 5 g (group E1) or 20 g (group E2) turmeric powder per 100 kg feed mixture (n=16 or 15, respectively). After 295 days, weight gain, conception and kindling rates, pup and mother viability, ovarian macro- and micro-morphometric indices, release of leptin in response to the addition LH, and the release of progesterone, testosterone and leptin by isolated ovarian fragments were analyzed. Dietary turmeric failed to affect ovarian length and weight but did increase the number of primary follicles (E2: 32.5% greater than control group), as well as the diameter of primary (E1: +19.4%, E2: +21.1%), secondary (E2: +41.4%), and tertiary (E1: +97.1%, E2: +205.1%) follicles. Turmeric also increased the number of liveborn (E1: +21.0%) and weaned (E1: +25.0%) pups and decreased the number of stillborn pups (E2: -87.5%) but did not affect weight gain, conception, or kindling rate. Furthermore, dietary turmeric decreased doe mortality during the first reproductive cycle (13.3% in control; 0% in E1; and 6.7% in E2) but not during the second cycle. In vitro, the ovaries of the turmeric-treated rabbits released more progesterone (E1: +85.7%, E2: +90.0%) and less testosterone (E2: -87.0%) and leptin (E2: -29.0%) than the ovaries of control rabbits. Moreover, LH decreased the leptin output of control rabbits but increased that of experimental rabbits. Therefore, it is likely that dietary turmeric improves pup viability and that it could promote rabbit fecundity by either (1) promoting the production of primary ovarian follicles or (2) stimulating the growth of follicles at all stages of folliculogenesis.

Fertility control of rodent pests: a review of the inhibitory effects of plant extracts on ovarian function.

PubMed

Tran, Tung Thanh; Hinds, Lyn A

Plant extracts can inhibit fertility by adversely affecting, directly or indirectly, reproductive processes ranging from gonadal function and development to gestation. This review focuses on plant extracts that disrupt ovarian function in rodents. Extracts from at least 40 plant species exert some of their disruptive reproductive effects at the ovarian level. Of those, 13 plants induce a reduction in the number and type of ovarian follicles and also cause disruption to the oestrous cycle. Their effects are short term and reversible once treatment ceases. Protection of plant extracts to prevent their degradation before uptake in the gastrointestinal tract could enhance short-term efficacy but would not enhance the longevity of their effects. Identification and further testing of the specific chemicals responsible for reproductive effects would be beneficial. The adoption of a standard protocol for treatment and assessment of the inhibitory effects of potential control agents on reproductive function in rodents is essential. Treatment with higher concentrations of extracts in conjunction with other extracts or with other chemosterilants could have potential complementary effects and lead to more rapid and permanent changes in ovarian function. An orally delivered agent(s) that causes major depletion of all follicle types, and particularly of non-regenerating primordial follicles, could be an ideal fertility control product and serve as an additional tool for population control of pest rodents.

Most reviews of IVF ovarian stimulation protocols have insufficiently accounted for various patient populations, such as ovulatory women, women with polycystic ovary syndrome (PCOS) or women with poor ovarian response, and have included studies in which the agonist or antagonist was not the only variable between the compared study arms. The aim of the current study was to compare GnRH antagonist protocols versus standard long agonist protocols in couples undergoing IVF or ICSI, while accounting for various patient populations and treatment schedules. The Cochrane Menstrual Disorders and Subfertility Review Group specialized register of controlled trials and Pubmed and Embase databases were searched from inception until June 2016. Eligible trials were those that compared GnRH antagonist protocols and standard long GnRH agonist protocols in couples undergoing IVF or ICSI. The primary outcome was ongoing pregnancy rate. Secondary outcomes were: live birth rate, clinical pregnancy rate, number of oocytes retrieved and safety with regard to ovarian hyperstimulation syndrome (OHSS). Separate comparisons were performed for the general IVF population, women with PCOS and women with poor ovarian response. Pre-planned subgroup analyses were performed for various antagonist treatment schedules. We included 50 studies. Of these, 34 studies reported on general IVF patients, 10 studies reported on PCOS patients and 6 studies reported on poor responders. In general IVF patients, ongoing pregnancy rate was significantly lower in the antagonist group compared with the agonist group (RR 0.89, 95% CI 0.82-0.96). In women with PCOS and in women with poor ovarian response, there was no evidence of a difference in ongoing pregnancy between the antagonist and agonist groups (RR 0.97, 95% CI 0.84-1.11 and RR 0.87, 95% CI 0.65-1.17, respectively). Subgroup analyses for various antagonist treatment schedules compared to the long protocol GnRH agonist showed a significantly lower ongoing pregnancy rate when the oral hormonal programming pill (OHP) pretreatment was combined with a flexible protocol (RR 0.74, 95% CI 0.59-0.91) while without OHP, the RR was 0.84, 95% CI 0.71-1.0. Subgroup analysis for the fixed antagonist schedule demonstrated no evidence of a significant difference with or without OHP (RR 0.94, 95% CI 0.79-1.12 and RR 0.94, 95% CI 0.83-1.05, respectively). Antagonists resulted in significantly lower OHSS rates both in the general IVF patients and in women with PCOS (RR 0.63, 95% CI 0.50-0.81 and RR 0.53, 95% CI 0.30-0.95, respectively). No data on OHSS was available from trials in poor responders. In a general IVF population, GnRH antagonists are associated with lower ongoing pregnancy rates when compared to long protocol agonists, but also with lower OHSS rates. Within this population, antagonist treatment prevents one case of OHSS in 40 patients but results in one less ongoing pregnancy out of every 28 women treated. Thus standard use of the long GnRH agonist treatment is perhaps still the approach of choice for prevention of premature luteinization. In couples with PCOS and poor responders, GnRH antagonists do not seem to compromise ongoing pregnancy rates and are associated with less OHSS and therefore could be considered as standard treatment. © The Author 2017.

Corifollitropin alfa compared with follitropin beta in poor responders undergoing ICSI: a randomized controlled trial.

Does substituting 150 µg corifollitropin alfa for 450 IU follitropin beta during the first 7 days of ovarian stimulation in proven poor responders, result in retrieval of a non-inferior number (<1.5 fewer) of cumulus oocyte complexes (COCs)? A single s.c. dose of 150 µg corifollitropin alfa on the first day of ovarian stimulation, followed if necessary, from Day 8 onwards, with 450 IU of follitropin beta/day, is not inferior to daily doses of 450 IU follitropin beta. The 95% CI of the difference between medians in the number of oocytes retrieved was -1 to +1 within the safety margin of 1.5. Recent data from retrospective studies suggest that the use of corifollitropin alfa in poor responders is promising since it could simplify ovarian stimulation without compromising its outcome. Seventy-nine women with previous poor ovarian response undergoing ICSI treatment were enrolled in this open label, non-inferiority, randomized clinical trial (RCT). Inclusion criteria were: previous poor response to ovarian stimulation (≤4 COCs) after maximal stimulation, age <45 years, regular spontaneous menstrual cycle, body mass index: 18-32 kg/m(2) and basal follicle stimulating hormone ≤20 IU/l. On Day 2 of the menstrual cycle, patients were administered either a single s.c dose of 150 µg corifollitropin alfa (n = 40) or a fixed daily dose of 450 IU of follitropin beta (n = 39). In the corifollitropin alfa group, 450 IU of follitropin beta were administered from Day 8 of stimulation until the day of human chorionic gonadotrophin (hCG) administration, if necessary. To inhibit premature luteinizing hormone surge, the gonadotrophin releasing hormone antagonist ganirelix was used. Triggering of final oocyte maturation was performed using 250 µg of recombinant hCG, when at least two follicles reached 17 mm in mean diameter. The number of COCs retrieved was not statistically different between the corifollitropin alfa and the follitropin beta groups [Median 3 versus 2, 95% CI 2-4, 2-3, respectively, P = 0.26]. The 95% CI of the difference between medians in the number of oocytes retrieved was -1 to +1. A multivariable analysis adjusting for all the potential baseline differences confirmed this finding. No significant difference was observed regarding the probability of live birth between the corifollitropin alfa and the follitropin beta group (live birth per patient reaching oocyte retrieval: 7.9 versus 2.6%, respectively, difference +5.3%, 95% CI: -6.8 to +18.3). The present study was not powered to test a smaller difference (e.g. 1 COC) in terms of COCs retrieved as well as to show potential differences in the probability of pregnancy. Moreover, it would be interesting to assess whether the continuation of stimulation in the long acting FSH arm, where necessary, with 200 IU instead of 450 IU of follitropin beta would have altered the direction or the magnitude of the effect of the type of FSH, observed on the number of COCs retrieved. Corifollitropin alfa simplifies IVF treatment because it is administered in a GnRH antagonist protocol and replaces seven daily FSH injections with a single one of a long acting FSH without compromising the outcome. It could greatly reduce the burden of treatment for poor responders and this deserves further investigation. © The Author 2014.

Dual protective role for Glutathione S-transferase class pi against VCD-induced ovotoxicity in the rat ovary

Keating, Aileen F.; Sen, Nivedita; Sipes, I. Glenn

2010-09-01

The occupational chemical 4-vinylcyclohexene diepoxide (VCD) selectively destroys ovarian small pre-antral follicles in rats and mice via apoptosis. Detoxification of VCD can occur through glutathione conjugation, catalyzed by glutathione S-transferase (GST) enzymes. Further, GST class pi (GSTp) can negatively regulate JNK activity through protein:protein interactions in extra-ovarian tissues. Dissociation of this protein complex in the face of chemical exposure releases the inhibition of pro-apoptotic JNK. Increased JNK activity during VCD-induced ovotoxicity has been shown in isolated ovarian small pre-antral follicles following in vivo dosing of rats (80 mg/kg/day; 15 days, i.p.). The present study investigated the pattern of ovarian GSTpmore » expression during VCD exposure. Additionally, the effect of VCD on an ovarian GSTp:JNK protein complex was investigated. PND4 F344 rat ovaries were incubated in control medium {+-} VCD (30 {mu}M) for 2-8 days. VCD increased ovarian GSTp mRNA (P < 0.05) relative to control on d4-d8; whereas GSTp protein was increased (P < 0.05) on d6-d8. A GSTp:JNK protein complex was detected by immunoprecipitation and Western blotting in ovarian tissues. Relative to control, the amount of GSTp-bound JNK was increased (P = 0.09), while unbound JNK was decreased (P < 0.05) on d6 of VCD exposure. The VCD-induced decrease in unbound JNK was preceded by a decrease in phosphorylated c-Jun which occurred on d4. These findings are in support of a possible dual protective role for GSTp in the rat ovary, consisting of metabolism of VCD and inhibition of JNK-initiated apoptosis.« less

One of the promising methods in fertility preservation among women with cancer is cryopreservation of ovarian cortex but there are many drawbacks such as apoptosis and considerable reduction of follicular density in the transplanted ovary. One solution to reduce ischemic damage is enhancing angiogenesis after transplantation of ovarian cortex tissue. The aim of this study was to investigate the effect of Setarud, on angiogenesis in transplanted human ovarian tissue. In this case control study, twenty four nude mice were implanted subcutaneously, with human ovarian tissues, from four women. The mice were randomly divided into two groups (n=12): the experimental group was treated with Setarud, while control group received only vehicle. Each group was divided into three subgroups (n=4) based on the graft recovery days post transplantation (PT). The transplanted fragments were removed on days 2, 7, and 30 PT and the expression of Angiopoietin-1, Angiopoietin-2, and Vascular endothelial growth factor at both gene and protein levels and vascular density were studied in the grafted ovarian tissues. On the 2(nd) and 7(th) day PT, the level of Angiopoietin-1 gene expression in case group was significantly lower than that in control group, while the opposite results were obtained for Angiopoietin-2 and Vascular endothelial growth factor. These results were also confirmed at the protein level. The density of vessels in Setarud group elevated significantly on day 7 PT compared to pre-treatment state. Our results showed that administration of Setarud may stimulates angiogenesis in transplanted human ovarian tissues, although further researches are needed before a clear judgment is made.

With early detection, five year survival rates for ovarian cancer are over 90%, yet no effective early screening method exists. Emerging consensus suggests that perhaps over 50% of the most lethal form of the disease, high grade serous ovarian cancer, originates in the Fallopian tube. Cancer changes molecular concentrations of various endogenous fluorophores. Using specific excitation wavelengths and emissions bands on a Multispectral Fluorescence Imaging (MFI) system, spatial and spectral data over a wide field of view can be collected from endogenous fluorophores. Wavelength specific reflectance images provide additional information to normalize for tissue geometry and blood absorption. Ratiometric combination of the images may create high contrast between neighboring normal and abnormal tissue. Twenty-six women undergoing oophorectomy or debulking surgery consented the use of surgical discard tissue samples for MFI imaging. Forty-nine pieces of ovarian tissue and thirty-two pieces of Fallopian tube tissue were collected and imaged with excitation wavelengths between 280 nm and 550 nm. After imaging, each tissue sample was fixed, sectioned and HE stained for pathological evaluation. Comparison of mean intensity values between normal, benign, and cancerous tissue demonstrate a general trend of increased fluorescence of benign tissue and decreased fluorescence of cancerous tissue when compared to normal tissue. The predictive capabilities of the mean intensity measurements are tested using multinomial logistic regression and quadratic discriminant analysis. Adaption of the system for in vivo Fallopian tube and ovary endoscopic imaging is possible and is briefly described.

Fibroblast growth factor (FGF)-2 (basic) is a potent angiogenic molecule involved in tumour progression, and is one of several growth factors with a central role in ovarian carcinogenesis. We hypothesised that common single nucleotide polymorphisms (SNPs) in the FGF2 gene may alter angiogenic potential and thereby susceptibility to ovarian cancer. We analysed 25 FGF2 tgSNPs using five independent study populations from the United States and Australia. Analysis was restricted to non-Hispanic White women with serous ovarian carcinoma (1269 cases and 2829 controls). There were no statistically significant associations between any FGF2 SNPs and ovarian cancer risk. There were two nominally statistically significant associations between heterozygosity for two FGF2 SNPs (rs308379 and rs308447; p<0.05) and serous ovarian cancer risk in the combined dataset, but rare homozygous estimates did not achieve statistical significance, nor were they consistent with the log additive model of inheritance. Overall genetic variation in FGF2 does not appear to play a role in susceptibility to ovarian cancer. PMID:19456219

CD157, an ADP-ribosyl cyclase-related cell surface molecule, regulates leukocyte diapedesis during inflammation. Because CD157 is expressed in mesothelial cells and diapedesis resembles tumor cell migration, we investigated the role of CD157 in ovarian carcinoma. We assayed surgically obtained ovarian cancer and mesothelial cells and both native and engineered ovarian cancer cell lines for CD157 expression using flow cytometry and reverse transcription-polymerase chain reaction (RT-PCR), and for adhesion to extracellular matrices, migration, and invasion using cell-based assays. We investigated invasion of human peritoneal mesothelial cells by serous ovarian cancer cells with a three-dimensional coculture model. Experiments were performed with or without CD157-blocking antibodies. CD157 expression in tissue sections from ovarian cancer patients (n = 88) was examined by immunohistochemistry, quantified by histological score (H score), and categorized as at or above or below the median value of 60, and compared with clinical parameters. Statistical tests were two-sided. CD157 was expressed by ovarian cancer cells and mesothelium, and it potentiated the adhesion, migration, and invasion of serous ovarian cancer cells through different extracellular matrices. CD157-transfected ovarian cancer cells migrated twice as much as CD157-negative control cells (P = .001). Blockage of CD157 inhibited mesothelial invasion by serous ovarian cancer cells in a three-dimensional model. CD157 was expressed in 82 (93%) of the 88 epithelial ovarian cancer tissue specimens. In serous ovarian cancer, patients with CD157 H scores of 60 or greater had statistically significantly shorter disease-free survival and overall survival than patients with lower CD157 H scores (CD157 H score > or =60 vs <60: median disease-free survival = 18 months, 95% confidence interval [CI] = 5.92 to 30.07 vs unreached, P = .005; CD157 H score > or =60 vs <60: median overall survival = 45 months, 95% CI = 21.21 to 68.79 vs unreached, P = .024). Multivariable Cox regression showed that CD157 is an independent prognostic factor for recurrence (hazard ratio of disease recurrence = 3.01, 95% CI = 1.35 to 6.70, P = .007) and survival (hazard ratio of survival = 3.44, 95% CI = 1.27 to 9.31, P = .015). CD157 plays a pivotal role in the control of ovarian cancer cell migration and peritoneal invasion, and it may be clinically useful as a prognostic tool and therapeutic target.

Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3' UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as with survival time. However, prior studies, emphasizing particular subgroups, were relatively small. Therefore, we comprehensively evaluated ovarian and breast cancer risks as well as clinical outcome associated with rs61764370. Centralized genotyping and analysis were performed for 140,012 women enrolled in the Ovarian Cancer Association Consortium (15,357 ovarian cancer patients; 30,816 controls), the Breast Cancer Association Consortium (33,530 breast cancer patients; 37,640 controls), and the Consortium of Modifiers of BRCA1 and BRCA2 (14,765 BRCA1 and 7904 BRCA2 mutation carriers). We found no association with risk of ovarian cancer (OR=0.99, 95% CI 0.94-1.04, p=0.74) or breast cancer (OR=0.98, 95% CI 0.94-1.01, p=0.19) and results were consistent among mutation carriers (BRCA1, ovarian cancer HR=1.09, 95% CI 0.97-1.23, p=0.14, breast cancer HR=1.04, 95% CI 0.97-1.12, p=0.27; BRCA2, ovarian cancer HR=0.89, 95% CI 0.71-1.13, p=0.34, breast cancer HR=1.06, 95% CI 0.94-1.19, p=0.35). Null results were also obtained for associations with overall survival following ovarian cancer (HR=0.94, 95% CI 0.83-1.07, p=0.38), breast cancer (HR=0.96, 95% CI 0.87-1.06, p=0.38), and all other previously-reported associations. rs61764370 is not associated with risk of ovarian or breast cancer nor with clinical outcome for patients with these cancers. Therefore, genotyping this variant has no clinical utility related to the prediction or management of these cancers. Copyright © 2015 Elsevier Inc. All rights reserved.

Ovarian cancer has a high mortality rate because there are few symptoms in early disease development. The incidence of ovarian cancer increases in women after menopause. Understanding early events in this disease can best be achieved by using animal models. Therefore, the objective of this study was to develop and track the onset of ovarian tumorigenesis in mice mimicking characteristics of postmenopausal epithelial cancer in women. Female B6C3F1 mice (age, 28 d) received 4-vinylcyclohexene diepoxide (VCD, 160 mg/kg IV daily for 20 d) to cause ovarian failure. Four months after VCD treatment, via surgical intervention, each mouse received a single injection of 7,12-dimethylbenz[a]anthracene (DMBA) or vehicle control (sesame oil) under the bursa of the right ovary to cause ovarian neoplasms. The experimental groups were untreated controls (Con–Con), DMBA-treatment only (Con–DMBA), VCD treatment only (VCD–Con), and VCD+DMBA-treated (VCD+DMBA) mice. At 3, 5, 7, and 9 mo after DMBA injection, ovaries were collected for histologic and immunohistochemical evaluation. No tumors developed in Con–Con mice. All VCD-treated mice (with or without DMBA) exhibited ovarian failure. Mice that received both VCD and DMBA exhibited tumors at 3 mo (50%), 5 mo (14%), 7 mo (90%), and 9 mo (57%) after DMBA treatment; 31% of the tumors were epithelial in origin. Our findings confirm that inducing ovarian tumors in mice by chemical means is an effective method for studying early stages of tumor development that may be relevant to epithelial ovarian cancers that arise in postmenopausal women.

Because no effective methods for preventing or screening for ovarian cancer exist, symptom recognition is integral to its early detection. The Centers for Disease Control and Prevention's Inside Knowledge: Get the Facts about Gynecologic Cancer campaign was developed to raise awareness and educate women and providers about risk factors, symptoms, recommended screening, and prevention strategies for the five main gynecologic cancers, including ovarian cancer. Inside Knowledge campaign materials were utilized by CDC's National Comprehensive Cancer Control Program grantees to educate women and providers about gynecologic cancer from 2014 to 2015. Grantees recruited participants and held educational sessions using Inside Knowledge materials. Questionnaires were given before and after the sessions to assess changes in awareness, confidence, and behavioral intentions around gynecologic cancer information and analyzed in 2016. This analysis focused on an assessment of changes related to ovarian cancer information. Participants' knowledge increased after educational sessions. Among women, there were increases in correctly identifying that the Papanicolaou (Pap) test does not screen for ovarian cancer (89.2%) and that genetic testing is available (77.9%). There was a lower increase in knowledge that HPV is not a cause of ovarian cancer (56.4%). Providers and women reported significant increases in their confidence in their ability to talk to each other about gynecologic cancer post-session. Ovarian cancer awareness, confidence, and related behaviors increased in participants exposed to Inside Knowledge materials. Using these materials to increase knowledge could lead to more empowered patients, better provider-patient communications, and improved care for gynecologic cancers, including ovarian cancer.

Are there any baseline predictors of progesterone elevation (PE) on the day of human chorionic gonadotrophin (hCG) which are not associated with the intensity of ovarian stimulation in women undergoing in vitro fertilization (IVF) using follicle stimulating hormone (FSH) and gonadotrophin-releasing hormone (GnRH) antagonists? Basal (Day 2 of the menstrual cycle) serum progesterone concentration and history of PE are baseline variables that can predict the occurrence of PE on the day of hCG independently of the intensity of ovarian stimulation. PE on the day of hCG is associated with the magnitude of the ovarian response to stimulation. For this reason, it has been hypothesized that milder ovarian stimulation might reduce the probability of PE. However, given the fact that the number of oocytes retrieved is associated with the probability of live birth, such a strategy should be considered only in patients that are at high risk of PE on the day of hCG. This is a retrospective analysis of a cohort of fresh IVF/ICSI cycles (n = 1702) performed in a single IVF centre during the period 2001-2015. Patients in whom ovarian stimulation was performed with FSH and GnRH antagonists and with basal FSH <14.0 mIU/ml, progesterone (P) ≤1.6 ng/ml and estradiol (E2) ≤80 pg/ml on the same day (prior to the initiation of stimulation) were considered eligible. PE was defined as serum progesterone concentration >1.5 ng/ml. Pre-stimulation characteristics of patients and basal hormonal profile were assessed for their ability to predict the occurrence of PE after ovarian stimulation through generalized estimating equation univariable and multivariable regression analyses, controlling for the effect of ovarian stimulation. Furthermore, a secondary analysis in a subset of patients with multiple IVF cycles explored whether the occurrence of PE in one of the previous cycles included in this study is associated with a significantly higher occurrence of PE elevation in subsequent cycles. Univariable regression analyses showed that female age (OR: 0.97; 95% CI: 0.94-0.99), basal FSH (OR: 0.85; 95% CI: 0.79-0.92) and basal P (OR: 4.20; 95% CI: 2.47-7.12) were baseline variables that could significantly predict PE on the day of hCG. When these variables were entered in the same model as covariates, only basal FSH (OR: 0.86; 95% CI: 0.80-0.94) and basal P (OR: 3.83; 95% CI: 2.24-6.56) could still predict the occurrence of PE. Basal P (OR: 6.30; 95% CI: 3.35-11.82) was the only variable that could significantly predict the occurrence of PE on the day of hCG after adjusting for the intensity of ovarian stimulation. The secondary analysis revealed that history of PE on the day of hCG in a previous cycle was also strongly associated with an increased risk of PE in a subsequent cycle. This is a retrospective analysis and although the effect of the most important confounders was controlled for in the multivariable analysis, the presence of residual bias cannot be excluded. The findings of this study might help clinicians identify patients at high risk for late follicular PE and alter the management of their cycle. None. Not applicable. © The Author 2016.

Ovarian cancer is the fifth most deadly cancer in women, and is usually diagnosed too late. Exploring specific and sensitive biomarkers will be helpful to early detection and will improve the survival rates of ovarian cancer patients. Realtime PCR was used to detect the expression of miR-376a. Wound healing and transwell assays were used to examined the migration and invasion abilities of ovarian cancer cells. Tumor xenograft experiments were employed to test the in vivo malignancy of ovarian cancer cells. Western Blotting and luciferase report assays were conducted for the target genes analysis. Using a cohort of 32 cases of ovarian cancer and 10 cases of healthy control samples, we found that miR-376 expression is increased in ovarian cancer tissues. The serum level of miR-376a is significantly higher in ovarian cancer patients and is associated with the clinical stages of ovarian cancer. Over expression of miR-376a stimulated the proliferation, migration, and invasion of ovarian cancer cells, while inhibition of miR-376a expression blocked the proliferation, migration, and invasion. Data from nude mice further demonstrated the stimulatory role of miR-376a in ovarian cancer progression. Mechanically, miR-376a played its role by targeting KLF15 and Caspase-8. Our findings enrich the knowledge of miR-376a in ovarian cancer formation and progression, providing a possibility of using miR-376a as a diagnostic and prognostic biomarker for ovarian cancer.

Breast cancer is one of the primary indications for cryopreservation and subsequent autotransplantation of ovarian tissue. The safety of this fertility preservation method remains questionable, as the presence of disseminated breast tumor cells cannot yet be excluded in the ovarian autografts. We explored the prevalence of ovarian metastases among young breast cancer patients and determined risk factors for the development of ovarian metastases. Using the nationwide database of the Dutch Pathology Registry (PALGA), we identified a cohort of 2648 women with primary invasive breast cancer at age < 41 years in the period 2000-2010 in the Netherlands who subsequently underwent an oophorectomy. From this source population, all cases who had histologically confirmed ovarian metastases were included. For each case of whom clinical data were available, one control without ovarian metastases who matched the time interval between breast cancer diagnosis and oophorectomy was selected. Data were collected on patient characteristics, diagnosis, treatment and follow-up. Ovarian metastases were found in 63 out of 2648 patients who met the inclusion criteria. The risk of developing ovarian metastases increased with time passed since breast cancer diagnosis. Multivariate logistic regression analyses showed significant association between tumor stage and the development of ovarian metastases (p = 0.024). The prevalence of ovarian metastases was 2.4% among young breast cancer patients. Early ovary removal may reduce the risk of developing ovarian metastases. In breast cancer patients with tumors > 5 cm and/or inflammatory carcinoma, we recommend a cautious approach to ovarian tissue autotransplantation.

The aim of the present study was to investigate the status of speckle-type POZ (pox virus and zinc finger protein) protein (SPOP) gene located on chromosome 17q21 in ovarian cancer (OC). The present study evaluated a tissue microarray, which contained 90 samples of ovarian cancer and 10 samples of normal ovarian tissue, using fluorescence in situ hybridization (FISH). FISH is a method where a SPOP-specific DNA red fluorescence probe was used for the experimental group and a centromere-specific DNA green fluorescence probe for chromosome 17 was used for the control group. The present study demonstrated that a deletion of the SPOP gene was observed in 52.27% (46/88) of the ovarian cancer tissues, but was not identified in normal ovarian tissues. Simultaneously, monosomy 17 was frequently identified in the ovarian cancer tissues, but not in the normal ovarian tissues. Furthermore, the present data revealed that the ovarian cancer histological subtype and grade were significantly associated with a deletion of the SPOP gene, which was assessed by the appearance of monosomy 17 in the ovarian cancer samples; the deletion of the SPOP gene was observed in a large proportion of serous epithelial ovarian cancer (41/61; 67.21%), particularly in grade 3 (31/37; 83.78%). In conclusion, deletion of the SPOP gene on chromosome 17 in ovarian cancer samples, which results from monosomy 17, indicates that the SPOP gene may serve as a tumor suppressor gene in ovarian cancer.

Endocrinology of recurrent pregnancy loss.

Arredondo, Francisco; Noble, Luis S

2006-02-01

Following implantation, the maintenance of the pregnancy is dependent on a multitude of endocrinological events that will eventually aid in the successful growth and development of the fetus. Although the great majority of pregnant women have no pre-existing endocrine abnormalities, a small number of women can have certain endocrine alterations that could potentially lead to recurrent pregnancy losses. It is estimated that approximately 8 to 12% of all pregnancy losses are the result of endocrine factors. During the preimplantation period, the uterus undergoes important developmental changes stimulated by estrogen, and more importantly, progesterone. Progesterone is essential for the successful implantation and maintenance of pregnancy. Therefore, disorders related to inadequate progesterone secretion by the corpus luteum are likely to affect the outcome of the pregnancy. Luteal phase deficiency, hyperprolactinemia, and polycystic ovarian syndrome are some examples. Several other endocrinological abnormalities such as thyroid disease, hypoparathyroidism, uncontrolled diabetes, and decreased ovarian reserve have been implicated as etiologic factors for recurrent pregnancy loss.

To observe the effect of electroacupuncture (EA) on ovarian P 450 arom and P 450 c 17 alpha (aromatases) expression and related sex hormone levels in polycystic ovary syndrome (PCOS) rats. Thirty SD rats were randomly divided into normal control group, model group and EA group (10 rats/group). PCOS model was made by intragastric administration of letrozole at 1 mg/kg per day for consecutive 21 days. "Guanyuan" (CV 4) and "Zhongji" (CV 3) acupoints were stimulated 20 min by EA (2 mA, 2 Hz), once daily for consecutive 14 days. The damp ovarian weight was weighed and the pathological changes of the ovarian tissue were observed after H. E. staining. Ultrastructural changes of the ovarian tissue were observed by transmission electron microscope. Immunohistochemical staining was adopted to detect ovarian follicle granulosa cell P 450 arom and follicle membrane cell P 450 c 17 alpha expression. The contents of estradiol (E 2), estrone (E 1), androstenedione (ASD), testosterone (T), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in the ovarian tissue were measured by ELISA. Compared with the normal group, there was a significant increase in the damp weight of both left and right ovarian tissues in the model group (P < 0.01). After EA, the ovarian weight was remarkably reduced (P < 0.01). Pathological changes of the ovarian tissue such as thickening of the superficial albugineous coat of the ovary, thinning of the granular cell layer, and disappearance of the intraovular oocytes and coronaradiata under light microscope, and mitochondrion swelling, fracture or disappearance of mitochondrial cristae, and enlargement of the endoplasmic reticulum, etc. after modeling were obviously improved in the EA group. In comparison to the control group, the expression of the follicle granulosa cell P450 arom was significantly down-regulated and that of follicle membrane cell P 450 c 17 alpha was significantly upregulated in the model group (P < 0.01). After EA intervention these changes were obviously reversed (P < 0.05, P < 0.01). In the model group, there was a significant increase in the levels of ASD, T and LH in the ovarian tissues (P < 0.01) and a marked decrease in the contents of ovarian E 1 and E2 (P < 0.01) in comparison to the control group. After EA, the ovarian ASD, T and LH levels were notably decreased (P < 0.05, P < 0.01) and the E 1 and E 2 levels apparently increased (P < 0.01) compared with the model group. EA can improve letrozole-induced pathological changes of ovarian morphology and ultrastructure and obviously promote P 450 arom expression in the follicle granulosa cell layer and inhibit P 450 c 17 alpha expression in the follicle membrane cell layer, as well as regulate sex hormone levels in PCOS rats, facilitating the normal transformation of ovarian androgen to estrogen and restoring the local endocrine disorders.

Effect of a GnRH-agonist (deslorelin) was studied on reproductive function and ovarian luteinizing hormone receptor (LHR) and follicle stimulating hormone receptor (FSHR) expression in prepubertal female cats that were either implanted with 4.7-mg deslorelin (implanted: n = 6) or not (controls: n = 18) or ovariohysterectomized at prepubertal age (prepubertal OVH: n = 6). Body weights, fecal estradiol, and sexual behavior of implanted and control cats were monitored for 48 weeks followed by collection of ovaries and uteri. Ovaries and uteri were collected from control cats at follicular, luteal, and inactive stage (n = 6/group) and from prepubertal OVH cats at prepubertal age. Ovaries and uteri were analyzed for anatomical/histological characteristics. Ovaries were also analyzed for LHR and FSHR expression. Statistical analysis showed higher (P ≤ 0.05) body weight in control than implanted cats only during 22nd to 26th weeks of the study. Estrus was observed in control cats only. Deslorelin reduced (P ≤ 0.05) ovarian weight and number of antral follicles but did not affect endometrial thickness and gland diameter. However, myometrial thickness of implanted cats was significantly lower than control cats at follicular and luteal stage. Ovarian LHR mRNA expression was lower (P ≤ 0.05) in implanted cats than control cats at follicular stage. FSHR mRNA and LHR protein expression did not differ among the three groups. FSHR protein expression was lower (P ≤ 0.05) in prepubertal OVH cats and was not affected by deslorelin. In conclusion, deslorelin suppresses reproductive function in prepubertal female cats for at least 48 weeks possibly through a change in the ovarian mRNA expression of LHR.

To study whether slush nitrogen vitrification improves the preservation of human ovarian tissue. Control vs. treatment study. University research laboratory. Ovarian biopsies collected from nine women (aged 14-35 years) during laparoscopic surgery for benign gynecologic conditions. None. Ovarian cortical strips of 2 × 5 × 1 mm were vitrified with liquid or slush nitrogen. Fresh and vitrified cortical strips were analyzed for cryodamage and viability under light, confocal, and transmission electron microscopy. Compared with liquid nitrogen, vitrification with slush nitrogen preserves [1] follicle quality (grade 1 follicles: fresh control, 50%; liquid nitrogen, 27%; slush nitrogen, 48%); [2] granulosa cell ultrastructure (intact cells: fresh control, 92%; liquid nitrogen, 45%; slush nitrogen, 73%), stromal cell ultrastructure (intact cells: fresh control, 59.8%; liquid nitrogen, 24%; slush nitrogen, 48.7%), and DNA integrity (TUNEL-positive cells: fresh control, 0.5%; liquid nitrogen, 2.3%; slush nitrogen, 0.4%); and [3] oocyte, granulosa, and stromal cell viability (oocyte: fresh control, 90%; liquid nitrogen, 63%; slush nitrogen, 87%; granulosa cells: fresh control, 93%; liquid nitrogen, 53%; slush nitrogen, 81%; stromal cells: fresh control, 63%; liquid nitrogen, 30%; slush nitrogen, 52%). The histology, ultrastructure, and viability of follicles and stromal cells are better preserved after vitrification with slush nitrogen compared with liquid nitrogen.

Sugary food and beverage consumption and epithelial ovarian cancer risk: a population-based case–control study

PubMed Central

2013-01-01

Background Ovarian cancer is the deadliest gynecologic cancer in the US. The consumption of refined sugars has increased dramatically over the past few decades, accounting for almost 15% of total energy intake. Yet, there is limited evidence on how sugar consumption affects ovarian cancer risk. Methods We evaluated ovarian cancer risk in relation to sugary foods and beverages, and total and added sugar intakes in a population-based case–control study. Cases were women with newly diagnosed epithelial ovarian cancer, older than 21 years, able to speak English or Spanish, and residents of six counties in New Jersey. Controls met same criteria as cases, but were ineligible if they had both ovaries removed. A total of 205 cases and 390 controls completed a phone interview, food frequency questionnaire, and self-recorded waist and hip measurements. Based on dietary data, we computed the number of servings of dessert foods, non-dessert foods, sugary drinks and total sugary foods and drinks for each participant. Total and added sugar intakes (grams/day) were also calculated. Multiple logistic regression models were used to estimate odds ratios and 95% confidence intervals for food and drink groups and total and added sugar intakes, while adjusting for major risk factors. Results We did not find evidence of an association between consumption of sugary foods and beverages and risk, although there was a suggestion of increased risk associated with sugary drink intake (servings per 1,000 kcal; OR=1.63, 95% CI: 0.94-2.83). Conclusions Overall, we found little indication that sugar intake played a major role on ovarian cancer development. PMID:23442818

A randomized controlled trial was conducted of a web-based intervention to improve advanced care planning in women with ovarian cancer. A secondary analysis of 35 randomized women focused on changes in distress and knowledge about ovarian cancer through distress monitoring and information tailored to patients' cognitive coping style (monitoring, blunting). Pre-/postresults indicated the Intervention group demonstrated lower distress (p = 0.06); blunting was associated with lower depression (p = 0.04); knowledge in both groups was unchanged. Women in the Intervention vs. Control group reported their family was less likely to be upset by cancer information (p = 0.0004). This intervention reduced distress while incorporating patient preferences.

What is the best source of ovarian cells for the artificial ovary: medulla or cortex, cryopreserved or fresh? Ovarian cells from fresh medullary tissue, which can be isolated in larger numbers, show higher viability and are able to improve graft vascularization. In a previous study, addition of endothelial cells along with ovarian cells was found to be crucial for formation of a well-vascularized ovary-like structure. This study is the first to evaluate both the effect of cryopreservation and the source of ovarian tissue on isolated ovarian cells. Prospective experimental study in an academic research unit using ovarian tissue from seven patients undergoing surgery for benign gynecologic disease. Ovarian tissue was retrieved from seven patients, with one half processed as fresh (fresh group) and the other half frozen and thawed before processing (frozen group). In each group, ovarian cells from the cortex and medulla were isolated separately, and their viability was tested using a calcein AM/ethidium homodimer viability assay. Fifty thousand cells were then encapsulated in fibrin and grafted to peritoneal pockets in nude mice (14 in all). Grafts recovered after 7 days were analyzed by immunohistochemistry for the presence of ovarian cells (vimentin), proliferation (Ki67) and graft vascularization (double CD34). Cell apoptosis was analyzed by TUNEL assay. Cryopreservation decreased ovarian cell yield (-2804 cells/mg, P = 0.015) and viability (-9.72%, P = 0.052) before grafting and had a considerable (5-fold, P = 0.2) but non-significant negative impact on ovarian cell presence in grafts. The medulla yielded many more cells (+3841 cells/mg, P < 0.001) with higher viability (+18.23%, P < 0.001) than did the cortex. Moreover, grafts with cells from the medulla exhibited a statistically significant 6.44- and 2.47-fold increase in human and total vascular surface area, respectively. P-values were adjusted for multiple testing using the Benjamini-Hochberg method to achieve a 10% false discovery rate and adjusted P-values < 0.1 were therefore considered significant. Pilot study involving a limited number of experiments. Knowing that fresh medullary tissue is the best source of stromal cells is important for construction of the artificial ovary, as isolated follicles require structural support and a rich vascular network for their survival and development.

Does endometrial injury in the cycle preceding ovarian stimulation for in vitro fertilization (IVF) improve the ongoing pregnancy rate in unselected subfertile women? Endometrial injury induced by endometrial aspiration in the preceding cycle does not improve the ongoing pregnancy rate in unselected subfertile women undergoing IVF. Implantation failure remains one of the major limiting factors for IVF success. Mechanical endometrial injury in the cycle preceding ovarian stimulation of IVF treatment has been shown to improve implantation and pregnancy rates in women with repeated implantation failures. There is limited data on unselected subfertile women, especially those undergoing their first IVF treatment. This randomized controlled trial recruited 300 unselected subfertile women scheduled for IVF/ICSI treatment between March 2011 and August 2013. Subjects were randomized into endometrial aspiration (EA) (n = 150) and non-EA (n = 150) groups according to a computer-generated randomization list. Subjects were recruited and randomized in the assisted reproductive unit at the University of Hong Kong. In the preceding cycle, women in the EA group underwent endometrial aspiration using a Pipelle catheter in mid-luteal phase. All women were treated with a cycle of IVF/ICSI. Pregnancy outcomes were compared. There were no significant differences in baseline or cycle characteristics between the groups. There were 209 subjects (69.7%) who were undergoing their first IVF cycle and 91 (30.3%) subjects who had repeated cycles. There was no significant difference in ongoing pregnancy rates [26.7% (40/150) versus 32.0% (48/150); RR 0.833 (95% CI 0.585-1.187), P = 0.375] in the EA and non-EA groups. The implantation rates [32.8% (67/204) versus 29.7% (68/229); RR 1.080 (95% CI 0.804-1.450), P = 0.120], clinical pregnancy rates [34.0% (51/150) versus 38.0 (57/150); RR 0.895 (95% CI 0.661-1.211), P = 0.548], miscarriage rates [30.3% (17/56) versus 18.6% (11/59), RR 1.628 (95% CI 0.838-3.164), P = 0.150] and multiple pregnancy rates [31.3% (16/51) versus 19.3% (11/57), RR 1.626 (95% CI 0.833-3.172), P = 0.154] were all comparable between the EA and non-EA groups. Subgroup analysis in women having first embryo transfer (n = 209) also demonstrated no significant difference in ongoing pregnancy rates, but for women undergoing repeated cycles (n = 91), the on-going pregnancy rate was significantly lower in the EA group than in the non-EA group. The study aimed at assessing an unselected population of subfertile women by recruiting consecutive women attending our fertility clinic. However, since the majority of the recruited women (69.7%) were having their first IVF treatments, the results may not be generalizable to all women undergoing IVF. Previous RCTs and meta-analyses have suggested improved pregnancy rates after pretreatment endometrial injury in women with repeated implantation failure. A recent RCT also showed increased pregnancy rates in unselected subfertile women after endometrial injury, although that study was terminated early and thus underpowered. Our study showed with adequate power that no significant improvement in pregnancy rates was observed after endometrial injury in unselected women undergoing IVF treatment. The study was supported by the Small Project Funding 201309176012 of the Committee on Research and Conference Grants, University of Hong Kong. The authors have nothing to disclose.

If a fresh embryo, assisted reproductive technology procedure cycle is unsuccessful and there are frozen embryos available, a frozen-thawed embryo transfer is performed. In some specific cases women may undergo oocyte donation treatment. In both situations the endometrium is primed by the administration of estrogen and progesterone. To prevent the possibility of spontaneous ovulation, gonadotropin-releasing hormone (GnRH) agonists are frequently used. To evaluate the most effective endometrial preparation for women undergoing transfer with frozen embryos or embryos from donor oocytes with regard to the subsequent live birth rate. We searched the Cochrane Menstrual Disorders and Subfertility Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, LILACS, and abstracts of reproductive societies' meetings (from inception). No language restrictions were applied. Experts in the field were contacted. Randomised controlled trials evaluating endometrial preparation in women undergoing fresh donor cycles and frozen embryo transfers. Two review authors independently applied the inclusion criteria, assessed trial risk of bias, and extracted data. Twenty two randomised controlled trials were included. Five studies analysed the use of a GnRH agonist versus control. No significant benefit was demonstrated when using GnRH agonists. No evidence of statistically significant benefit was found for one GnRH agonist over another, or vaginal over intramuscular progesterone administration. No difference in pregnancy rate was demonstrated when no treatment was compared to aspirin, steroids, ovarian stimulation, or human chorionic gonadotropin (hCG) prior to embryo transfer, although using hCG several times before the oocyte retrieval decreases the pregnancy rate. Finally, when oocyte recipients were studied further, starting progesterone on the day of oocyte pick-up (OPU) or the day after OPU produced a significantly higher pregnancy rate (OR 1.87, 95% CI 1.13 to 3.08) than when recipients started progesterone the day prior to OPU. There is insufficient evidence to recommend any one particular protocol for endometrial preparation over another with regard to pregnancy rates after embryo transfers. These were either frozen embryos or embryos derived from donor oocytes. However, there is evidence of a lower pregnancy rate and a higher cycle cancellation rate when the progesterone supplementation is commenced prior to oocyte retrieval in oocyte donation cycles. Adequately powered studies are needed to evaluate each treatment more accurately.

Aberrant glycosylation is a well-described hallmark of cancer. In a previous ovarian cancer case control study that examined polymorphisms in 26 glycosylation-associated genes, we found strong statistical evidence (P = 0.00017) that women who inherited two copies of a single-nucleotide polymorphism in the UDP-N-acetylgalactosamine:polypeptide N-acetylgalactosaminyltransferase, GALNT1, had decreased ovarian cancer risk. The current study attempted to replicate this observation. The GALNT1 single-nucleotide polymorphism rs17647532 was genotyped in 6,965 cases and 8,377 controls from 14 studies forming the Ovarian Cancer Association Consortium. The fixed effects estimate per rs17647532 allele was null (odds ratio, 0.99; 95% confidence interval, 0.92–1.07). When a recessive model was fit, the results were unchanged. Test for hetero geneity of the odds ratios revealed consistency across the 14 replication sites but significant differences compared with the original study population (P = 0.03). This study underscores the need for replication of putative findings in genetic association studies. PMID:20142253

Congenital adrenal hyperplasia (CAH) is a group of disorders affecting the adrenal steroid synthesis. The most common form, 21-hydroxylase deficiency (21-OHD), leads to decreased production of cortisol and aldosterone with increased androgen secretion. In classic CAH, glucocorticoid treatment can be life-saving and serves to bring the symptoms under control. However, the treatment challenge is to effectively control the excess androgen effect by using the lowest possible glucocorticoid dose. Previous studies suggested a relationship between ovarian cyst formation and adrenal androgen excess, but neonatal large ovarian cysts have been very rarely reported in newborns with CAH. Here, we present the unique case of a neonate with classical 21-OHD who underwent surgery for a giant (10x8x7 cm) unilateral solitary ovarian follicular cyst on the 2nd postnatal day. Hormonal evaluation of the patient revealed high-dose hook effect for serum testosterone levels for the first time by a two-site immunoradiometric assay. Possible mechanisms by which androgen excess may cause ovarian cyst formation are discussed.

The objective of this study is to explore the effects of amygdala kindling on estrus cycle and ovarian morphology. Thirty-five female rats at the age of 8 weeks were randomly designated to electrode kindled, sham-kindled, and normal controls. Kindled rats were implanted with kindling electrodes in the left basolateral amygdala and kindled by brief suprathreshold stimulations with a bipolar electrode. Estrous cycles were daily monitored through vaginal smears. Electrographic and behavioral seizures were recorded and ovarian morphology was evaluated by light and electron microscopies. Our results showed that the kindled rats lost their ovarian periodicity displayed significant ovarian enlargement. H&E staining revealed increased number of growing follicles and total follicles, as well as polycysts in the ovaries of the kindled animals compared to sham and control animals. Ultrastructural study detected numerous apoptotic granulosa cells in growing follicles and thecal cell hyperplasia with secretary granules in the thecal cells in the kindled rats. The results suggest that amygdala kindling is a risk factor for the development of polycystic ovary syndrome. PMID:25285307

Epidemiology of epithelial ovarian cancer.

Globally, ovarian cancer is the seventh most common cancer in women and the eighth most common cause of cancer death, with five-year survival rates below 45%. Although age-standardised rates are stable or falling in most high-income countries, they are rising in many low and middle income countries. Furthermore, with increasing life-expectancy, the number of cases diagnosed each year is increasing. To control ovarian cancer we need to understand the causes. This will allow better prediction of those at greatest risk for whom screening might be appropriate, while identification of potentially modifable causes provides an opportunity for intervention to reduce rates. In this paper we will summarise the current state of knowledge regarding the known and possible causes of epithelial ovarian cancer and discuss some of the main theories of ovarian carcinogenesis. We will also briefly review the relationship between lifestyle and survival after a diagnosis of ovarian cancer. Copyright © 2016. Published by Elsevier Ltd.

To assess the clinicopathological significance of survivin in ovarian carcinoma through this meta-analysis. PubMed, EMBASE, Web of Science, and The Cochrane Library databases were searched for relevant studies published through September, 2017. Included studies reported the case-control study of surviving expression with ovarian cancer and its clinicopathological characteristics. The quality assessment was performed according to the Newcastle-Ottawa Scale (NOS) for quality assessment of case-control studies. Statistical analysis was performed with the software Stata 12.0. Twelve eligible studies with a total of 1097 patients were included in this meta-analysis. Survivin overexpression was closely related to FIGO stage (I-II vs. III-IV) of ovarian carcinoma (odds ratio [OR] = 0.26,95% confidence interval [CI]:0.16,0.42),P<0.00001),tumor grade (G1-G2 vs. G3) (OR = 0.29,95%CI(0.17, 0.51),P <0.0001), but was not significantly associated with lymphatic metastasis (OR = 1.53, 95%CI(0.77, 3.03, P = 0.23),ascites (OR = 0.89,95%CI(0.39,2.05),P = 0.79). Our meta-analysis shows that survivin is strongly associated with FIGO stage and tumor grade of ovarian carcinoma. Maybe survivin is a novel clinicopathological marker of ovarian carcinoma.

Background The significance of polycystic ovarian morphology and its relation to polycystic ovary syndrome (PCOS) is unclear, but probably it is associated with higher androgen and insulin levels and lower sex hormone binding globulin (SHBG) in absence of identifiable differences in gonadotropin dynamics. The aim of this study was to evaluate ovarian morphology in patients affected by PCOS with different ovulatory responses to metformin. Methods In this cross-sectional analysis, we studied 20 young normal-weight PCOS patients who had received a six-month course of metformin treatment. Ten of these patients remained anovulatory (anovulatory group), whereas other ten became ovulatory, but failed to conceive (ovulatory group). Other ten age- and body mass index (BMI)-matched PCOS subjects were also enrolled as controls and observed without any treatment (control group). Results After six months of metformin, in both PCOS treated groups, a similar improvement in testosterone (T) and insulin resistance indexes was observed. Moreover, in one (10.0%) and nine (90.0%) subjects from anovulatory and ovulatory PCOS groups, respectively, ovarian morphology changed, whereas a significant reduction in ovarian dimension was observed in the PCOS ovulatory group only. Conclusion PCOS patients under metformin administration demonstrate a change in ovarian morphology closely related to ovulatory response. PMID:19480717

Small volume residual peritoneal disease in patients undergoing therapy for ovarian carcinoma remains an attractive, but elusive, target for immunobiological therapy. Hypothetical advantages and disadvantages of regional peritoneal therapy are being better defined through increased clinical experience and more sophisticated animal models. Developments in cytokine biology, adoptive cellular therapy, monoclonal antibody conjugation, and molecular biology continue to provide an exciting, and nearly overwhelming, array of reagents for clinical evaluation. Ongoing and anticipated investigational trials should provide intriguing data in years to follow.198 references.

To compare clomiphene citrate (CC) and letrozole for ovarian stimulation (OS) in therapeutic donor sperm insemination (TDI) cycles. Retrospective cohort study between January 2011 and June 2014 at a University-affiliated private IVF clinic in Montreal, Canada. 257 normo-ovulatory women ≤40 years of age with no history of infertility undergoing 590 TDI cycles in the absence of a male partner (single women and same-sex couples) or azoospermia were included. Patients received 100 mg CC daily (145 women, 321 cycles) or letrozole 5 mg daily (112 women, 269 cycles), from days 3 to 7. Only the first 3 cycles were included per patient. Our main outcome measure was cumulative live birth rates (LBR). Baseline characteristics were comparable between the 2 groups. There were no differences in LBR per cycle (16.5% (53/321) vs. 11.5% (31/269), p = 0.08) and cumulative LBR (36.6% (53/145) vs. 27.7% (31/112), p = 0.13), between CC and letrozole, respectively. Multiple pregnancy rate (11.6% (8/69) vs. 8.7% (4/46), p = 0.6) and miscarriage rate (21.7 vs. 21.7%, p = 1) were also comparable between CC and letrozole, respectively. In normo-ovulatory women undergoing TDI, OS with CC or letrozole resulted in similar live birth and twin pregnancy rates. © 2016 S. Karger AG, Basel.

Lymphatic complications are a common occurrence after staging surgery for early-stage ovarian cancer (eEOC). We investigated whether the introduction of minimally invasive surgery influences the risk of developing lymphoceles and lymphorrhea in patients undergoing staging for eEOC. For this purpose, data of consecutive patients affected by eEOC undergoing staging surgery between January 1980 and January 2016 were retrospectively reviewed, and a systematic review and meta-analysis was performed. This systematic review was registered in the International Prospective Register of Systematic Review. Among 341 patients included in the present study, 47 severe postoperative complications occurred (13.7%), including 40 lymphatic complications: 31 symptomatic lymphoceles (9%) and 9 cases of lymphorrhea (2.6%), respectively. Laparoscopic staging correlated with a lower risk of developing any severe lymphatic complications in comparison with open surgery (p = .02). In particular, the laparoscopic approach and para-aortic node involvement were associated with a trend toward lower lymphoceles (odds ratio, .13; 95% confidence interval, .07-2.20; p = .05) and a trend toward higher risk of lymphorrhea developing (odds ratio, 4.02; 95% confidence interval, .93-17.3; p = .06), respectively. In conclusion, the implementation of a minimally invasive approach might result in a slight reduction of lymphatic complications after eEOC staging. Copyright © 2017 AAGL. Published by Elsevier Inc.

The aim of the present study was to investigate the antitumor activities of naringin in ovarian cancer, and to assess the underlying mechanisms. Ovarian tumor cells were implanted into nude mice to produce ovarian tumors in vivo . The mice were divided into six groups: Control, low dose naringin [0.5 mg/kg, intraperitoneal (i.p.)], middle dose naringin (1 mg/kg, i.p.), high dose naringin (2 mg/kg, i.p.), positive control (cisplatin, 2 mg/kg, i.p.) and a combination of cisplatin and naringin (both 2 mg/kg). Following administration of naringin and/or cisplatin, the tumor size and weight were measured. Apoptosis of tumor cells was detected using a terminal deoxynucleotidyl transferase dUTP nick end labeling assay. Apoptosis-associated gene expression was detected using reverse transcription-polymerase chain reaction and immunohistochemistry. In the range of 0.5-2 mg/kg, naringin dose-dependently inhibited tumor growth, as demonstrated by a decrease in tumor size and weight. Naringin promoted apoptosis of the ovarian tumor cells. Additionally, naringin reduced the expression of B-cell lymphoma (Bcl)-2, Bcl-extra large (Bcl-xL), cyclin D1, c-Myc and survivin, while it increased the expression of caspase-3 and caspase-7. The data demonstrated that naringin inhibited ovarian tumor growth in vivo . Its mechanisms may be associated with caspase-7-, caspase-3-, Bcl-2- and Bcl-xL-mediated apoptosis. Nevertheless, the clinical application of naringin in the treatment of ovarian cancer requires further study.

Altered global DNA methylation is indicative of epigenomic instability concerning chronic diseases. Investigating its incidence and association with polycystic ovary syndrome (PCOS) is essential to understand the etiopathogenesis of this disorder. We assessed global DNA methylation differences in peripheral blood leukocytes (PBLs) and cumulus granulosa cells (CGCs) of controls and women with PCOS; and their association with PCOS and its traits. This study included a total of 102 controls and women with PCOS. Forty-one women undergoing controlled ovarian hyperstimulation (COH) and 61 women not undergoing COH were recruited from in vitro fertilization (IVF) and infertility clinics. DNA methylation was measured by ELISA for 5'-methyl-cytosine content and bisulfite sequencing of 5'-untranslated region (5'-UTR) of long interspersed nucleotide element-1 (LINE1/L1). Total 5'-methyl-cytosine and L1 methylation levels in PBLs and CGCs were similar between controls and women with PCOS. Methylation assessed at CpG sites of L1 5'-UTR revealed a single CpG-site (CpG-4) to be consistently hypomethylated in PBLs of both PCOS groups and CGCs of stimulated PCOS group. In unstimulated women, hypomethylation at CpG-4 was strongly associated with PCOS susceptibility, whereas in stimulated group it showed strong associations with PCOS and its hormonal traits. Furthermore, CGCs demonstrated consistent global and CpG-DNA hypomethylation relative to PBLs, irrespective of normal or disease states. Our study revealed strong association of single hypomethylated CpG-site with PCOS. Identification and characterization of more such methyl-CpG signatures in repetitive elements in larger study populations would provide valuable epigenetic insights into PCOS.

Epithelial ovarian cancer is diagnosed less than 25% of the time when the cancer is confined to the ovary, leading to 5-year survival rates of less than 30%. Therefore, there is an urgent need for early diagnostics for ovarian cancer. Our study using glycotranscriptome comparative analysis of endometrioid ovarian cancer tissue and normal ovarian tissue led to the identification of distinct differences in the transcripts of a restricted set of glycosyltransferases involved in N-linked glycosylation. Utilizing lectins that bind to glycan structures predicted to show changes, we observed differences in lectin-bound glycoproteins consistent with some of the transcript differences. In this study, we have extended our observations by the use of selected lectins to perform a targeted glycoproteomic analysis of ovarian cancer and normal ovarian tissues. Our results have identified several glycoproteins that display tumor-specific glycosylation changes. We have verified these glycosylation changes on glycoproteins from tissue using immunoprecipitation followed by lectin blot detection. The glycoproteins that were verified were then analyzed further using existing microarray data obtained from benign ovarian adenomas, borderline ovarian adenocarcinomas, and malignant ovarian adenocarcinomas. The verified glycoproteins found to be expressed above control levels in the microarray data sets were then screened for tumor-specific glycan modifications in serum from ovarian cancer patients. Results obtained from two of these glycoprotein markers, periostin and thrombospondin, have confirmed that tumor-specific glycan changes can be used to distinguish ovarian cancer patient serum from normal serum.

Abstract The age-related decline in ovarian response to gonadotropins has been well known since the beginning of ovarian stimulation in IVF cycles and has been considered secondary to the age-related decline in ovarian reserve. The objective of this study was to establish reference values and to construct nomograms of ovarian response for any specific age to gonadotropins in IVF/ICSI cycles. We analyzed our database containing information on IVF cycles. According to inclusion and exclusion criteria, a total of 703 patients were selected. Among inclusion criteria, there were regular menstrual cycle, treatment with a long GnRH agonist protocol and starting follicle-stimulating hormone (FSH) dose of at least 200 IU per day. To estimate the reference values of ovarian response, the CG-LMS method was used. A linear decline in the parameters of ovarian response with age was observed: the median number of oocytes decreases approximately by one every three years, and the median number of follicles >16 mm by one every eight years. The number of oocytes and growing follicles corresponding to the 5th, 25th, 50th, 75th and 95th centiles has been calculated. This study confirmed the well known negative relationship between ovarian response to FSH and female ageing and permitted the construction of nomograms of ovarian response.

There are large variations in the number of oocytes within each woman, and biologically, the total quantity is at its maximum before the woman is born. Scientific knowledge is limited about factors controlling the oocyte pool and how to measure it. Within fertility clinics, there is no uniform agreement on the diagnostic criteria for each common measure of ovarian reserve in women, and thus, studies often conflict. While declining oocyte quantity/quality is a normal physiologic occurrence as women age, some women experience diminished ovarian reserve (DOR) much earlier than usual and become prematurely infertile. Key clinical features of DOR are the presence of regular menstrual periods and abnormal-but-not-postmenopausal ovarian reserve test results. A common clinical challenge is counseling patients with conflicting ovarian reserve test results. The clinical diagnosis of DOR and the interpretation of ovarian reserve testing are complicated by changing lab testing options and processing for anti-mullerian hormone since 2010. Further, complicating the diagnostic and research scenario is the existence of other distinct yet related clinical terms, specifically premature ovarian failure, primary ovarian insufficiency, poor ovarian response, and functional ovarian reserve. The similarities and differences between the definitions of DOR with each of these four terms are reviewed. We recommend greater medical community involvement in terminology decisions, and the addition of DOR-specific medical subject-heading search terms.

To evaluate whether oral contraceptive pill (OCP) therapy has any effects on ovarian stromal blood flow by using pulsed and color Doppler at the end of 3 months follow-up period of OCP-users and non-users with or without polycystic ovary syndrome (PCOS). 200 patients were included in the study. The patients were designed into four groups as follows; Group 1: PCOS patients that received OCP containing 30 mcg ethinyl estradiol (EE) plus 3mg drospirenone for 3 months (DRP n=50); Group 2: PCOS patients that received no medication (n=50); Group 3: Healthy controls that received OCP (EE plus DRP) (n=50); Group 4: healthy controls that received no medication (n=50). Resistance index (RI) and pulsatility index (PI) of both ovarian arteries, hormonal, anthropometric and biochemical parameters were assessed before and after 3 months. There was a significant increament in RI and PI of both ovarian arteries in healthy controls (Group 3) and in women with PCOS (Group 1) who received OCP (p<0.001). The increment rate in both Doppler parameters were significantly higher in women with PCOS (Group 1) than healthy controls (Group 3) (p<0.001). Whereas RI and PI values of both ovaries remained unchanged in all untreated women with or without PCOS (Groups 2 and 4). OCP therapy reduced ovarian vascularization in both PCOS and healthy users after 3 months of therapy and this decrease is especially noticeable in women with PCOS.

Early diagnosis of epithelial ovarian cancer is critical for patient survival. The objective of this pilot study is to identify a circulating micro (mi)RNA as a potential biomarker for epithelial ovarian cancer. A total of 135 epithelial ovarian cancer patients and 54 benign ovarian tumor patients were recruited for this study. Using customized TaqMan low density miRNA arrays, we first screened expression levels of 48 miRNAs in sera from 18 epithelial ovarian cancer patients and 16 benign ovarian tumor patients. The most significantly and differentially expressed miRNA was then further examined in all serum samples using real-time polymerase chain reaction. Its expression was further analyzed in relationship with clinicopathological factors and patient survival. Array screening data showed that expression levels of serum miRNA-20a, miRNA-125b, miRNA-126, miRNA-355, and let-7c were significantly different between malignant and benign ovarian tumor patients. Subsequent real-time polymerase chain reaction results showed that serum miRNA-125b levels were significantly higher in epithelial ovarian cancer patients compared to benign controls. Moreover, serum miRNA-125b levels were significantly higher in ovarian cancer patients in early stages I and II, and in patients having no residual tumor following surgery, but were not associated with differentiation and histological types of ovarian cancer. Notably, the higher level of miR-125b was significantly positively correlated with progression-free survival (P = 0.035) and marginally, with overall survival (P = 0.069). miRNA-125b plays an important role in the pathogenesis and progression of epithelial ovarian cancer. Circulating miRNA-125b has the potential to become a novel biomarker for early diagnosis and prognosis prediction of epithelial ovarian cancer.

Summary Background Endometriosis is a risk factor for epithelial ovarian cancer; however, whether this risk extends to all invasive histological subtypes or borderline tumours is not clear. We undertook an international collaborative study to assess the association between endometriosis and histological subtypes of ovarian cancer. Methods Data from 13 ovarian cancer case–control studies, which were part of the Ovarian Cancer Association Consortium, were pooled and logistic regression analyses were undertaken to assess the association between self-reported endometriosis and risk of ovarian cancer. Analyses of invasive cases were done with respect to histological subtypes, grade, and stage, and analyses of borderline tumours by histological subtype. Age, ethnic origin, study site, parity, and duration of oral contraceptive use were included in all analytical models. Findings 13 226 controls and 7911 women with invasive ovarian cancer were included in this analysis. 818 and 738, respectively, reported a history of endometriosis. 1907 women with borderline ovarian cancer were also included in the analysis, and 168 of these reported a history of endometriosis. Self-reported endometriosis was associated with a significantly increased risk of clear-cell (136 [20·2%] of 674 cases vs 818 [6·2%] of 13 226 controls, odds ratio 3·05, 95% CI 2·43–3·84, p<0·0001), low-grade serous (31 [9·2%] of 336 cases, 2·11, 1·39–3·20, p<0·0001), and endometrioid invasive ovarian cancers (169 [13·9%] of 1220 cases, 2·04, 1·67–2·48, p<0·0001). No association was noted between endometriosis and risk of mucinous (31 [6·0%] of 516 cases, 1·02, 0·69–1·50, p=0·93) or high-grade serous invasive ovarian cancer (261 [7·1%] of 3659 cases, 1·13, 0·97–1·32, p=0·13), or borderline tumours of either subtype (serous 103 [9·0%] of 1140 cases, 1·20, 0·95–1·52, p=0·12, and mucinous 65 [8·5%] of 767 cases, 1·12, 0·84–1·48, p=0·45). Interpretation Clinicians should be aware of the increased risk of specific subtypes of ovarian cancer in women with endometriosis. Future efforts should focus on understanding the mechanisms that might lead to malignant transformation of endometriosis so as to help identify subsets of women at increased risk of ovarian cancer.

Ovarian cancer is a disease of older women. However, the molecular mechanisms of ovarian aging and their contribution to the pathogenesis of ovarian cancer are currently unclear. mTOR signalling is a major regulator of aging as suppression of this pathway extends lifespan in model organisms. Overactive mTOR signalling is present in up to 80% of ovarian cancer samples and is associated with poor prognosis. This study examined the role of mTOR signalling in age-associated changes in ovarian surface epithelium (OSE). Histological examination of ovaries from both aged mice and women revealed OSE cell hyperplasia, papillary growth and inclusion cysts. These pathological lesions expressed bonafide markers of ovarian cancer precursor lesions, Pax8 and Stathmin 1, and were presented with elevated mTOR signalling. To understand whether overactive mTOR signalling is responsible for the development of these pathological changes, we analysed ovaries of the Pten trangenic mice and found significant reduction in OSE lesions compared to controls. Furthermore, pharmacological suppression of mTOR signalling significantly decreased OSE hyperplasia in aged mice. Treatment with mTOR inhibitors reduced human ovarian cancer cell viability, proliferation and colony forming ability. Collectively, we have established the role of mTOR signalling in age-related OSE pathologies and initiation of ovarian cancer. PMID:27036037

Purpose To demonstrate the functional, clinical and biological significance of JNK-1 in ovarian carcinoma. Experimental Design Analysis of the impact of JNK on 116 epithelial ovarian cancers was conducted. The role of JNK in vitro and in experimental models of ovarian cancer was assessed. We studied the role of WBZ_4, a novel JNK inhibitor redesigned from imatinib based on targeting wrapping defects, in cell lines and in experimental models of ovarian cancer. Results We found a significant association of pJNK with progression free survival in the 116 epithelial ovarian cancers obtained at primary debulking therapy. WBZ_4 led to cell growth inhibition and increased apoptosis in a dose dependent fashion in four ovarian cancer cell lines. In vivo, while imatinib had no effect on tumor growth, WBZ_4 inhibited tumor growth in orthotopic murine models of ovarian cancer. The anti-tumor effect was further increased in combination with docetaxel. Silencing of JNK-1 with systemically administered siRNA led to significantly reduced tumor weights as compared to non-silencing siRNA controls, indicating that indeed the antitumor effects observed were due to JNK-1 inhibition. Conclusions These studies identify JNK-1 as an attractive therapeutic target in ovarian carcinoma and that the re-designed WBZ_4 compound should be considered for further clinical development.

Several prostate cancer susceptibility loci have recently been identified by genome-wide association studies. These loci are candidates for susceptibility to other epithelial cancers. The aim of this study was to test these tag single nucleotide polymorphisms (SNP) for association with invasive ovarian, colorectal, and breast cancer. Twelve prostate cancer-associated tag SNPs were genotyped in ovarian (2,087 cases/3,491 controls), colorectal (2,148 cases/2,265 controls) and breast (first set, 4,339 cases/4,552controls; second set, 3,800 cases/3,995 controls) case-control studies. The primary test of association was a comparison of genotype frequencies between cases and controls, and a test for trend stratified by study where appropriate. Genotype-specific odds ratios (OR) were estimated by logistic regression. SNP rs2660753 (chromosome 3p12) showed evidence of association with ovarian cancer [per minor allele OR, 1.19; 95% confidence interval (95% CI), 1.04-1.37; Ptrend = 0.012]. This association was stronger for the serous histologic subtype (OR, 1.29; 95% CI, 1.09-1.53; P = 0.003). SNP rs7931342 (chromosome 11q13) showed some evidence of association with breast cancer (per minor allele OR, 0.95; 95% CI, 0.91-0.99; Ptrend = 0.028). This association was somewhat stronger for estrogen receptor-positive tumors (OR, 0.92; 95% CI, 0.87-0.98; P = 0.011). None of these tag SNPs were associated with risk of colorectal cancer. In conclusion, loci associated with risk of prostate cancer may also be associated with ovarian and breast cancer susceptibility. However, the effects are modest and warrant replication in larger studies. PMID:18974127

Disruption in circadian gene expression, whether due to genetic variation or environmental factors (e.g., light at night, shiftwork), is associated with increased incidence of breast, prostate, gastrointestinal and hematologic cancers and gliomas. Circadian genes are highly expressed in the ovaries where they regulate ovulation; circadian disruption is associated with several ovarian cancer risk factors (e.g., endometriosis). However, no studies have examined variation in germline circadian genes as predictors of ovarian cancer risk and invasiveness. The goal of the current study was to examine single nucleotide polymorphisms (SNPs) in circadian genes BMAL1, CRY2, CSNK1E, NPAS2, PER3, REV1 and TIMELESS and downstream transcription factors KLF10 and SENP3 as predictors of risk of epithelial ovarian cancer (EOC) and histopathologic subtypes. The study included a test set of 3,761 EOC cases and 2,722 controls and a validation set of 44,308 samples including 18,174 (10,316 serous) cases and 26,134 controls from 43 studies participating in the Ovarian Cancer Association Consortium (OCAC). Analysis of genotype data from 36 genotyped SNPs and 4600 imputed SNPs indicated that the most significant association was rs117104877 in BMAL1 (OR = 0.79, 95% CI = 0.68–0.90, p = 5.59 × 10−4]. Functional analysis revealed a significant down regulation of BMAL1 expression following cMYC overexpression and increasing transformation in ovarian surface epithelial (OSE) cells as well as alternative splicing of BMAL1 exons in ovarian and granulosa cells. These results suggest that variation in circadian genes, and specifically BMAL1, may be associated with risk of ovarian cancer, likely through disruption of hormonal pathways. PMID:26807442

Over 22,000 cases of ovarian cancer were diagnosed in 2007 in the United States but only a fraction of them can be attributed to mutations in highly penetrant genes such as BRCA1. To determine whether low penetrance genetic variants contribute to ovarian cancer risk, we genotyped 1,536 single nucleotide polymorphisms (SNPs) in several candidate gene pathways in 848 epithelial ovarian cancer cases and 798 controls in the North Carolina Ovarian Cancer Study (NCO) using a customized Illumina array. The inflammation gene interleukin-18 (IL18) showed the strongest evidence for association with epithelial ovarian cancer in a gene-by-gene analysis (p=0.002) with a <25% chance of being a false positive finding (q-value=0.240). Using a multivariate model search algorithm over eleven IL18 tagging SNPs, we found the association was best modeled by rs1834481. Further, this SNP uniquely tagged a significantly associated IL18 haplotype and there was an increased risk of epithelial ovarian cancer per rs1834481 allele (OR=1.24, 95% CI: 1.06, 1.45). In a replication stage, twelve independent studies from the Ovarian Cancer Association Consortium (OCAC) genotyped rs1834481 in an additional 5,877 cases and 7,791 controls. The fixed effects estimate per rs1834481 allele was null (OR=0.99, 95% CI: 0.94, 1.05) when data from the twelve OCAC studies were combined. The effect estimate remained unchanged with the addition of the initial NCO data. This analysis demonstrates the importance of consortia, like the OCAC, in either confirming or refuting the validity of putative findings in studies with smaller sample sizes. PMID:19064572

Women with autoimmune Addison's disease with normal ovulatory cycles but positive for steroid cell antibodies (StCA) have been considered at risk of premature ovarian insufficiency (POI). Thirty-three women younger than 40 years, with subclinical-clinical autoimmune Addison's disease but with normally ovulatory menses, were followed up for 10 years to evaluate the long-term time-related variations of StCA, ovarian function and follicular reserve. All patients and 27 control women were investigated at the start and every year for the presence and titre of StCA (by indirect immunofluorescence), serum concentrations of anti-Mullerian hormone (AMH) and ovarian function at four consecutive menses every year. At the start of the study StCA were present in 16 women (group 1), at low/middle titres (≤1:32) in seven of them (43.8%, group 1A), at high titres (>1:32) in the remaining nine patients (group 1B, 56.2%), while they were absent from 17 patients (group 2). During the follow-up period, all women in group 1A remained StCA-positive at low/middle titres with normal ovulatory menses and normal gonadotrophin and AMH levels, while all patients in group 1B showed a further increase of StCA titres (1:128-1:256) and progressed through three stages of ovarian function. None of the patients in group 2 and controls showed the appearance of StCA or ovarian dysfunction during the follow-up. The presence of StCA at high titres can be considered a good predictive marker of subsequent development of autoimmune POI. To single out the stages of autoimmune POI may allow a timely therapeutic choice in the subclinical and early clinical stages. © 2017 European Society of Endocrinology.

Background The identification of sensitive biomarkers for the detection of ovarian cancer is of high clinical relevance for early detection and/or monitoring of disease recurrence. We developed a systematic multi-step biomarker discovery and verification strategy to identify candidate DNA methylation markers for the blood-based detection of ovarian cancer. Methodology/Principal Findings We used the Illumina Infinium platform to analyze the DNA methylation status of 27,578 CpG sites in 41 ovarian tumors. We employed a marker selection strategy that emphasized sensitivity by requiring consistency of methylation across tumors, while achieving specificity by excluding markers with methylation in control leukocyte or serum DNA. Our verification strategy involved testing the ability of identified markers to monitor disease burden in serially collected serum samples from ovarian cancer patients who had undergone surgical tumor resection compared to CA-125 levels. We identified one marker, IFFO1 promoter methylation (IFFO1-M), that is frequently methylated in ovarian tumors and that is rarely detected in the blood of normal controls. When tested in 127 serially collected sera from ovarian cancer patients, IFFO1-M showed post-resection kinetics significantly correlated with serum CA-125 measurements in six out of 16 patients. Conclusions/Significance We implemented an effective marker screening and verification strategy, leading to the identification of IFFO1-M as a blood-based candidate marker for sensitive detection of ovarian cancer. Serum levels of IFFO1-M displayed post-resection kinetics consistent with a reflection of disease burden. We anticipate that IFFO1-M and other candidate markers emerging from this marker development pipeline may provide disease detection capabilities that complement existing biomarkers. PMID:22163280

Cryopreservation of the ovarian tissue has shown promising results. However, there remain controversial issues such as the short half-life of grafts. In this aspect, there are some evidences that preconditioning the ovarian tissue before transplantation is beneficial. To determine the effect of hypoxic preconditioning in vitro on ovarian tissue prior to transplantation. Eighteen female adult Wistar rats, were sorted into three experimental groups. Ovaries were maintained in DMEM low glucose serum free at 37°C with 5% CO2, at atmospheric oxigen concentration (normoxia) or 1% O2 (hypoxia) for 16 hours. Oxigen concentration was determined by injection of nitrogen in the incubator. Animals submitted to ovarian transplantation immediately after oophorectomy were the Control Group (C). After this, the ovaries were implanted in the retroperitoneum with nonabsorbable suture and animals evaluated for thirty days after transplantation. Beginning on postoperative (PO) day 11, a daily collection of vaginal smear was carried out. Analyses comprised morphological, morphometric (counting ovarian follicles and corpora lutea) and immunohistochemistry for cleaved caspase-3 (apoptosis). In normoxia and control groups all animals recovered their estrous cycles, while in the hypoxia group, two animals did not ovulate but, among those which did, resumption took longer than in the other groups (p < 0.05). The number of ovarian follicles and corpora lutea decreased significantly in the hypoxia group when compared to the other two groups (p < 0.001) and apoptosis was increased in the few ovarian follicles which remained viable (p < 0.001). The hypoxic preconditioning in vitro was not beneficial to the graft and worsened their viability, compromising its functionality or delaying the return of this.

Objective To assess ovarian follicle function in women with 46,XX spontaneous primary ovarian insufficiency Design Case-control with nested prospective cohort Setting Clinical Research Center, National Institutes of Health Patients Women with primary ovarian insufficiency without estrogen replacement for two weeks (N=97) and regularly menstruating control women (N=42) Interventions Single injection of 300 IU hrFSH Main outcome measures Change in serum estradiol at 24 hours Results Antral follicles ≥ 3 mm were detected in 73% (69/95) of patients; both serum estradiol and progesterone levels correlated significantly with maximum follicle diameter in these women. Patients with a maximum follicle diameter ≥ 8 mm had significantly higher serum estradiol and progesterone levels and significantly lower FSH and LH levels as compared to patients without such follicles. In controls estradiol levels increased significantly after FSH administration but in patients this was not the case despite the presence of an antral follicle ≥ 8 mm. Conclusion Most women with 46,XX spontaneous primary ovarian insufficiency have antral follicles detectable by ultrasound, suggesting that down-regulation of FSH receptors is not the predominant mechanism of follicle dysfunction. Evidence of progesterone secretion by antral follicles ≥ 8 mm in these patients is consistent with prior histologic evidence that follicle luteinization is the predominant mechanism of follicle dysfunction in this condition. Prospective controlled investigation designed to improve ovulatory function and fertility in these women is indicated. PMID:19939372

Ovarian cancer is the third most common gynaecological cancer worldwide, with an age-standardised incidence rate of 6.1 per 10,000 women. Standard therapy for advanced epithelial ovarian cancer (EOC) includes a combination of cytoreductive surgery and platinum-based chemotherapy. Cytoreductive surgery aims to remove as much of the visible tumour as possible. As extensive intraperitoneal metastases are typical of advanced EOC, cytoreductive surgery is usually an extensive procedure with the risk of excessive bleeding. Tranexamic acid given perioperatively is effective in reducing blood loss and allogeneic blood transfusion requirements in a variety of surgical settings. Therefore, tranexamic acid seems to be a promising agent for minimising blood loss and the need for blood transfusion among women with advanced EOC undergoing cytoreductive surgery. To assess the effects of tranexamic acid for reducing blood loss associated with cytoreductive surgery in women with advanced EOC (stage III to IV). We searched the Cochrane Gynaecological, Neuro-oncology and Orphan Cancers Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 5, 2015), MEDLINE, EMBASE and conference proceedings to May 2015. We also checked registers of clinical trials, citation lists of included studies, key textbooks and previous systematic reviews for potentially relevant studies. We included randomised controlled trials (RCTs) comparing tranexamic acid given during surgery versus placebo or no treatment, in adult women diagnosed with advanced EOC. Two review authors (CK, AS) independently selected potentially relevant trials, extracted data, assessed risk of bias, compared results and resolved disagreements by discussion. We found only one study that met our inclusion criteria. This was a randomised double blind, placebo-controlled multicentre study conducted to evaluate the effectiveness of a single dose of intravenous tranexamic acid (15 mg/kg body weight) versus placebo, given immediately before surgery for reducing blood loss and the need for red blood cell transfusion. The mean total estimated blood loss was 668.34 mL and 916.93 mL for participants assigned to tranexamic acid and placebo groups, respectively. The mean difference (MD) of total estimated blood loss between the groups did not show a clinically important effect (MD - 248.59 mL; 95% confidence interval (CI) - 550.9 to 53.79; one study, 100 participants; moderate quality evidence). The mean number of transfused units of blood components was not different between the two groups (low quality evidence). There were no noted differences in the incidence of reoperation, readmission or thromboembolic events (very low quality evidence). We considered the methodology of the included study to be at low risk of selection, detection, and reporting biases. However, we were concerned about an imbalance of some baseline characteristics between the groups, and as there was no protocol for blood transfusion, the rate of blood transfusion may vary depending on the practice of each participating hospital. Currently, there is insufficient evidence to recommend the routine use of tranexamic acid for reducing blood loss in women undergoing cytoreductive surgery for advanced EOC, as only limited data are available from a single, low quality RCT at low overall risk of bias.

Although many patients try to seek acupuncture to improve in vitro fertilization (IVF) outcomes, evidence regarding its efficacy and acupoints characters are lacking. The aim of this protocol is to evaluate the effectiveness and safety, as well as the acupoints characteristics of acupuncture in the treatment of female undergoing IVF, by conducting a systematic review and data mining. The following 6 databases will be searched from their inception to April 30, 2018: PubMed, Chinese National Knowledge Infrastructure, Wanfang, VIP database, Embase, and Cochrane Library. The randomized controlled trials (RCTs) or case-control studies of acupuncture that assess clinical effects and side effects in female undergoing IVF are included. The primary outcome measures will be number of oocytes retrieved, fertilization rate, oocyte cleavage rate, high-quality embryos rate, ovarian hyperstimulation syndrome (OHHS) incidence rate, clinical pregnancy rate (CPR), biochemical pregnancy rate (BPR), implantation rate, and cycle cancellation rate. Two reviewers will independently undertake data extraction and quality assessments. Data will be synthesized by RevMan V.5.3 software. Acupoints characteristics will be excavated using Traditional Chinese Medicine inheritance support system (TCMISS). Reporting bias will be assessed by Funnel plots, Begg test, and Egger test. This review will assess the clinical efficacy and safety, as well as the acupoints characteristics of acupuncture on IVF. These findings will summarize the current evidence of acupuncture on IVF outcomes and may provide guidance for clinicians and infertile women to select acupuncture for IVF.

A diagnosis of ovarian cysts is likely an indicator of hormonal milieu and thus may be related to breast cancer risk. Recent studies have reported an inverse relationship between prior ovarian cyst diagnosis and breast cancer risk. We evaluated this relationship in the Women's Contraceptive and Reproductive Experiences (CARE) Study, a population-based case-control study conducted in Atlanta, Detroit, Philadelphia, Los Angeles, and Seattle. Cases had first primary invasive breast cancer diagnosed between 1994 and 1998 at ages 35-64 years. African American women were over-sampled. Controls were identified through random digit dialling and were frequency matched to cases on centre, race, and five-year age group. A total of 4575 cases and 4682 controls were interviewed. We used unconditional logistic regression adjusted for age and study centre within racial groups to estimate the odds ratio (OR) and 95% confidence interval (CI) for the relationship between prior ovarian cysts and breast cancer. Ovarian cyst diagnosis was associated with a significantly reduced risk among Caucasians (OR=0.85, 95% CI 0.76-0.96) and among African Americans (OR=0.68, 95% CI 0.57-0.81). The association in Caucasians was not significant within subgroups defined by menopausal status, hormone use, or gynecological surgery while the OR estimates in African Americans were consistently lower and frequently significant. These data are consistent with the previously reported inverse association between ovarian cysts and breast cancer, but the evidence for a relationship was stronger in African Americans than Caucasians. Additional studies are required to determine the specific cyst type(s) responsible for the observed relationship.

Classic galactosemia is a potentially lethal genetic disorder resulting from profound impairment of galactose-1P uridylyltransferase (GALT). More than 80% of girls and women with classic galactosemia experience primary or premature ovarian insufficiency despite neonatal diagnosis and rigorous lifelong dietary galactose restriction. The goal of this study was to test the relationship between markers of ovarian reserve, cryptic residual GALT activity, and spontaneous pubertal development in girls with classic galactosemia. This was a cross-sectional study with some longitudinal follow-up in a university research environment. Patients included girls and women with classic galactosemia and unaffected controls, <1 month to 30 years old. We evaluated plasma anti-Müllerian hormone (AMH) and FSH levels, antral follicle counts ascertained by ultrasound, and ovarian function as indicated by spontaneous vs assisted menarche. More than 73% of the pre- and postpubertal girls and women with classic galactosemia in this study, ages >3 months to 30 years, demonstrated AMH levels below the 95% confidence interval for AMH among controls of the same age, and both pre- and postpubertal girls and women with classic galactosemia also demonstrated abnormally low antral follicle counts relative to age-matched controls. Predicted residual GALT activity ≥ 0.4% significantly increased the likelihood that a girl with classic galactosemia would demonstrate an AMH level ≥ 0.1 ng/mL. A majority of girls with classic galactosemia demonstrate evidence of diminished ovarian reserve by 3 months of age, and predicted cryptic residual GALT activity is a modifier of ovarian function in galactosemic girls and women.

Women with a single ovary present a unique problem in assisted reproductive techniques. The aim of our study was to compare the ovarian response and pregnancy rates of women with one ovary and those with two ovaries in assisted reproduction. A total of 18 consecutive women with a single ovary (n is 22 cycles) were identified. The control group included 44 women with two ovaries and mechanical infertility, who were selected as frequency-matched samples (2:1) to meet the distribution of age at treatment and race in the single ovary group. All patients underwent controlled ovarian hyperstimulation treatment via the long down-regulation protocol using a gonadotropin-releasing hormone agonist. Standard procedures were carried out for gamete-embryo handling, and embryo transfer was performed using a soft catheter on day two in all cases. The luteal phase was supported by progesterone or Pregnyl after oocyte pick-up. The duration of stimulation (11.3 +/- 1.7 versus 10.1 +/- 1.4 days) and the total follicle stimulating hormone (FSH) consumption (3906.8 +/- 1860.6 mIU/ml versus 2900.0 +/- 1440.0 mIU/ml) were significantly higher, and the mean number of oocytes (10.8 +/- 4.5 versus 16.8 +/- 10.9) and metaphase II oocytes collected (9.5 +/- 4.5 versus 13.3 +/- 7.7) were significantly lower in the single ovary group (p is less than 0.05). The clinical pregnancy rates (31.8 percent versus 43.2 percent) were comparable between the two groups. Although women with a single ovary required significantly higher doses of FSH and a longer duration of stimulation, as well as produced less oocytes, their clinical pregnancy rates were comparable to those of women with two ovaries in assisted reproduction.

Management of women with reduced ovarian reserve or poor ovarian response (POR) to stimulation is one of the major challenges in reproductive medicine. The primary causes of POR remain elusive and oxidative stress was proposed as one of the important contributors. It has been suggested that focus on the specific subpopulations within heterogeneous group of poor responders could assist in evaluating optimal management strategies for these patients. This study investigated the effect of anti-oxidant treatment with coenzyme Q10 (CoQ10) on ovarian response and embryo quality in young low-prognosis patients with POR. This prospective, randomized controlled study included 186 consecutive patients with POR stratified according to the POSEIDON classification group 3 (age < 35, poor ovarian reserve parameters). The participants were randomized to the CoQ10 pre-treatment for 60 days preceding IVF-ICSI cycle or no pre-treatment. The number of high quality embryos was a primary outcome measure. A total of 169 participants were evaluated (76 treated with CoQ10 and 93 controls); 17 women were excluded due to low compliance with CoQ10 administration. The baseline demographic and clinical characteristics were comparable between the groups. CoQ10 pretreatment resulted in significantly lower gonadotrophin requirements and higher peak E2 levels. Women in CoQ10 group had increased number of retrieved oocytes (4, IQR 2-5), higher fertilization rate (67.49%) and more high-quality embryos (1, IQR 0-2); p < 0.05. Significantly less women treated with CoQ10 had cancelled embryo transfer because of poor embryo development than controls (8.33% vs. 22.89%, p = 0.04) and more women from treatment group had available cryopreserved embryos (18.42% vs. 4.3%, p = 0.012). The clinical pregnancy and live birth rates per embryo transfer and per one complete stimulation cycle tended to be higher in CoQ10 group but did not achieve statistical significance. Pretreatment with CoQ10 improves ovarian response to stimulation and embryological parameters in young women with poor ovarian reserve in IVF-ICSI cycles. Further work is required to determine whether there is an effect on clinical treatment endpoints.

The aim of this study was to compare the effect of corifollitropin alfa (CFA) and recombinant follicle-stimulating hormone (rFSH) in poor-responder patients undergoing antagonist cycles. The study was a retrospective analysis of the treatment results of 214 poor responder patients who had been admitted to the In Vitro Fertilization Unit of İzmir Medical Park Hospital between November 2014 and November 2016. Intracytoplasmic sperm injections were performed in 38 patients (group 1) with CFA, and the remaining 176 (group 2) with rFSH for controlled ovarian hyperstimulation. The age, body mass index, anti-müllerian hormone level, duration of infertility, duration of induction and antral follicle number were similar in the two groups. There was no difference in the total aspirated oocyte counts, mature oocyte ratio, fertilization rate, implantation rate, and clinical pregnancy rates between the two groups. The implantation rate was 9/38 (23.6%) in group 1 and 42/176 (23.8%) in group 2, whereas the clinical pregnancy rates were 16.3% and 17.2%, respectively. No difference was found in terms of oocyte count, fertilization rate, implantation rate, and clinical pregnancy rates of CFA or rFSH use in the antagonist cycles in poor-responder patients.

Menopausal estrogen-alone therapy (ET) is a well-established risk factor for serous and endometrioid ovarian cancer. Genetics also plays a role in ovarian cancer, which is partly attributable to 18 confirmed ovarian cancer susceptibility loci identified by genome-wide association studies. The interplay among these loci, ET use and ovarian cancer risk has yet to be evaluated. We analyzed data from 1,414 serous cases, 337 endometrioid cases and 4,051 controls across 10 case-control studies participating in the Ovarian Cancer Association Consortium (OCAC). Conditional logistic regression was used to determine the association between the confirmed susceptibility variants and risk of serous and endometrioid ovarian cancer among ET users and non-users separately and to test for statistical interaction. A splicing variant in TERT, rs10069690, showed a statistically significant interaction with ET use for risk of serous ovarian cancer (p int  = 0.013). ET users carrying the T allele had a 51% increased risk of disease (OR = 1.51, 95% CI 1.19-1.91), which was stronger for long-term ET users of 10+ years (OR = 1.85, 95% CI 1.28-2.66, p int  = 0.034). Non-users showed essentially no association (OR = 1.08, 95% CI 0.96-1.21). Two additional genomic regions harboring rs7207826 (C allele) and rs56318008 (T allele) also had significant interactions with ET use for the endometrioid histotype (p int  = 0.021 and p int  = 0.037, respectively). Hence, three confirmed susceptibility variants were identified whose associations with ovarian cancer risk are modified by ET exposure; follow-up is warranted given that these interactions are not adjusted for multiple comparisons. These findings, if validated, may elucidate the mechanism of action of these loci. © 2016 UICC.

Background Hormonal and reproductive factors contribute to the development of ovarian cancer, but few studies have examined associations between circulating estrogens and estrogen metabolites and ovarian cancer risk. We evaluated whether serum estrogens and estrogen metabolite levels are associated with ovarian cancer risk among postmenopausal women in a nested case-control study in the Women’s Health Initiative (WHI) Observational Study (OS). Methods We selected all 169 eligible epithelial ovarian cancer cases and 412 matched controls from women enrolled in WHI-OS who were not using menopausal hormones at baseline. Baseline levels of 15 estrogens and estrogen metabolites were measured via LC-MS/MS. Associations with ovarian cancer risk overall and stratified by histologic subtype (serous/non-serous) were analyzed using logistic regression. The mean time from serum collection to cancer diagnosis was 6.9 years. Results Overall we observed modest ovarian cancer risk associations among women with higher levels of estrone [Odds Ratio (95% Confidence Interval) quintile (Q)5 vs. Q1: 1.54 (0.82–2.90), p-trend=0.05], as well as 2- and 4-methoxyestrone metabolites [2.03 (1.06–3.88), p-trend=0.02; 1.86 (0.98–3.56), p-trend=0.01, respectively]. Associations of estrogens and estrogen metabolites varied substantially by histologic subtype. Associations with serous tumors were universally null, while estrone (2.65 (1.09–6.45), p-trend=0.01, p-heterogeneity=0.04), unconjugated estradiol (2.72 (1.04–7.14), p-trend=0.03, p-heterogeneity=0.02) and many of the 2-, 4-, and 16-pathway metabolites were positively associated with non-serous tumors. Conclusions Our study provides novel molecular data showing an association of the parent estrogens and several estrogen metabolites with non-serous ovarian cancers. Impact These findings further support the heterogeneous etiology of ovarian cancer. PMID:26908437

Aspirin, Nonaspirin Nonsteroidal Anti-inflammatory Drug, and Acetaminophen Use and Risk of Invasive Epithelial Ovarian Cancer: A Pooled Analysis in the Ovarian Cancer Association Consortium

PubMed Central

2014-01-01

Background Regular aspirin use is associated with reduced risk of several malignancies. Epidemiologic studies analyzing aspirin, nonaspirin nonsteroidal anti-inflammatory drug (NSAID), and acetaminophen use and ovarian cancer risk have been inconclusive. Methods We analyzed pooled data from 12 population-based case–control studies of ovarian cancer, including 7776 case patients and 11843 control subjects accrued between 1992 and 2007. Odds ratios (ORs) for associations of medication use with invasive epithelial ovarian cancer were estimated in individual studies using logistic regression and combined using random effects meta-analysis. Associations between frequency, dose, and duration of analgesic use and risk of ovarian cancer were also assessed. All statistical tests were two-sided. Results Aspirin use was associated with a reduced risk of ovarian cancer (OR = 0.91; 95% confidence interval [CI] = 0.84 to 0.99). Results were similar but not statistically significant for nonaspirin NSAIDs, and there was no association with acetaminophen. In seven studies with frequency data, the reduced risk was strongest among daily aspirin users (OR = 0.80; 95% CI = 0.67 to 0.96). In three studies with dose information, the reduced risk was strongest among users of low dose (<100mg) aspirin (OR = 0.66; 95% CI = 0.53 to 0.83), whereas for nonaspirin NSAIDs, the reduced risk was strongest for high dose (≥500mg) usage (OR = 0.76; 95% CI = 0.64 to 0.91). Conclusions Aspirin use was associated with a reduced risk of ovarian cancer, especially among daily users of low-dose aspirin. These findings suggest that the same aspirin regimen proven to protect against cardiovascular events and several cancers could reduce the risk of ovarian cancer 20% to 34% depending on frequency and dose of use.

Current evidence suggests that the presence of tumor-initiating cells (TICs) in epithelial ovarian cancer (EOC) has a role in chemoresistance and relapse. Surface markers such as CD44(+)/CD24(-), CD117(+), and CD133(+) expression have been reported as potential markers for TICs related to ovarian cancer and tumorigenic cell lines. In this study, we have investigated if spheroid forms are TIC specific or whether they can also be produced by somatic stem cells from healthy tissue in vitro. In addition, we also investigated the specificity of surface markers to identify TICs from papillary serous EOC patients. Cells were obtained from fresh tumors from 10 chemotherapy-naive patients with EOC, and cells from ovarian and tubal epithelium were obtained from 5 healthy menopausal women undergoing surgery for benign pathology and cultured in standard and in selective medium. Cells forming nonadherent spheroids were considered TICs, and the adherent cells were considered as non-TIC-like. Percentages of CD24(+), CD44(+), CD117(+), CD133(+), and vascular endothelial growth factor receptor (VEGF-R)(+) cell surface markers were analyzed by flow cytometry. Four of 10 EOC cell tissues were excluded from the study. Tumor cells cultured in selective medium developed spheroid forms after 1 to 7 weeks in 5 of 6 EOC patients. No spheroid forms were observed in cultures of cells from healthy women. Unlike previously published data, low levels of CD24(+), CD44(+), CD117(+), and VEGF-R(+) expression were observed in spheroid cells, whereas expression of CD133(+) was moderate but higher in adherent cells from papillary serous EOC cells in comparison with adherent cells from controls. Papillary serous EOC contains TICs that form spheroids with low expression of CD44(+), CD24(+), CD117(+) and VEGF-R(+). Further research is required to find specific surface markers to identify papillary serous TICs.

In Japan, awareness of hereditary breast and ovarian cancer (HBOC) has gradually increased among health care workers and the general population. We focus on two current topics: genetic testing and risk-reducing surgery for HBOC. Genetic testing for BRCA1 and BRCA2, the genes responsible for HBOC, is performed to diagnose HBOC. PCR-direct sequencing is a standard method used for BRCA1/2 mutation analysis. Recently, genetic rearrangement of BRCA1 was reported in a Japanese patient with HBOC. Therefore, MLPA tests are also being included in routine genetic testing for the disease. The result of "uncertain significance, " which indicates unclear pathogenic significance, is obtained in about 3% of all patients who undergo BRCA1/2 genetic tests. Furthermore, novel candidate genes for HBOC, such as RAD51C, PALB2, and BRIP1, were recently identified. Prophylactic surgical intervention for HBOC includes procedures such as risk-reducing bilateral salpingo-oophorectomy (RRSO) and risk-reducing mastectomy(RRM). In Japan, RRSO is performed in very few patients at present. Increasing evidence from overseas indicates that RRSO contributes to a decreased incidence of ovarian/breast cancers and lowers overall mortality. Therefore, a system for performing RRSO was established in our institute. RRSO was approved to be performed as a clinical examination by our Institutional Review Board. The clinical significance of ipsilateral complete mastectomy and RRM remains unclear. Based on the NCCN guidelines, conservative mastectomy with radiation therapy is relatively contraindicated in patients with HBOC. However, several studies have reported that conservative mastectomy with radiation the rapydoes not increase the incidence of recurrent or metachronous breast cancers in the ipsilateral breast of mutation-positive patients when compared to mutation-negative or control patients. However, more aggressive malignancies seem to be included in the mutation-positive group(especially BRCA1 -mutation-positive cases). RRM clearly reduced the incidence of breast cancers. RRM may also be allowed as a treatment option for HBOC in Japan.

Peritoneal gliomatosis is characterized by the presence of miliary implants of mature glia on the peritoneum of patients with ovarian teratomas, usually immature. We report the case of a woman operated on 5 years earlier due to a right mature ovarian teratoma. When she was operated on due to left ovarian tumor she presented a miliary glial dissemination in omentum and peritoneum. The association of peritoneal gliomatosis ovarian teratomas is rare. Although the primary treatment and patient monitoring is focused on the teratoma, control should be maintained of peritoneal implants because of the possibility of malignancy. We believe it would be beneficial to establish a protocol for monitoring these lesions.

Risks of conservative management in women with ovarian endometriomas undergoing IVF.

Classical surgical management of endometriotic ovarian cysts using the laparoscopic stripping technique has been recently questioned because of the surgical-related injury to the ovarian reserve. Accordingly, available guidelines suggest that endometriomas with a mean diameter below 4 cm should not be systematically removed before IVF procedures. However, conservative management may have some potential drawbacks and risks. The presence of the endometrioma may theoretically interfere with ovarian responsiveness to hyperstimulation and oocyte competence, the retrieval of the oocytes may be more difficult and risky, the disease may progress during the procedure, pregnancy outcome may be affected and there is the risk of missing occult malignancies with cancer development later in life. In the present review, we aimed at assessing whether these risks do exist and, if so, at estimating their clinical relevance. We searched PubMed for articles published in the English language between January 1990 and August 2014 that reported on endometriomas and assisted reproductive techniques. Special care was given to studies reporting data purporting to distinguish the effects of ovarian endometriomas per sé from those consequent to surgery for endometriosis or from endometriosis in general. Based on the evidence reviewed in the present study, it can be concluded that conservative management may actually expose women to four of the following theoretical risks, i.e. infection of the endometriomas, follicular fluid contamination with the endometrioma content, higher risk of pregnancy complications and cancer development later in life. The first three conditions do not justify surgery because these events are uncommon and the number of women needed to be treated would be exceedingly high and would not justify the costs and risks of the intervention. Albeit also very rare, the possibility of developing ovarian cancer later in life is more troublesome because it is a life-threatening condition. However, this alarmism is supported by only one cohort study and this risk can be effectively prevented by postponing surgery until after the IVF programme is concluded or when women have definitely satisfied their reproductive wishes. The available evidence on the risks of conservative management does not support systematic surgery before IVF in women with small ovarian endometriomas. © The Author 2015.
