    The fifth leading cause of cancer-related deaths among women in the United States is ovarian cancer. An estimated 21,980 new cases and 14,270 estimated deaths occurred nationwide in 2014. More than two-thirds of cases of ovarian cancer are diagnosed at stage III or IV when the peritoneal cavity or other organs are affected. Primary appendiceal malignant neoplasms may mimic advanced-stage ovarian cancer and can be misdiagnosed because of its presentation as a palpable adnexal mass. The authors describe a 42-year-old woman who was admitted to the department of obstetrics and gynecology to receive treatment for presumed advanced-stage ovarian cancer. She subsequently received a diagnosis of primary pseudomyxoma peritonei metastatic to the ovaries, mimicking a primary ovarian cancer by osteopathic structural examination findings, serum tumor markers, surgical exploration, and histopathologic confirmation.

    Abstract To evaluate the incidence of secondary primary malignancy (SPM) in patients with ovarian cancer using a nationwide retrospective population-based dataset. Patients newly diagnosed with ovarian cancer between 1997 and 2010 were identified using Taiwan's National Health Insurance database. Patients with antecedent malignancies were excluded. Standardized incidence ratios (SIRs) for SPM were calculated and compared with the cancer incidence in the general population. Risk factors for cancer development were analyzed using Cox proportional hazard models. Effects of surgery, chemotherapy, and radiotherapy after ovarian cancer diagnosis were regarded as time-dependent variables to prevent immortal time bias. During the 14-year study period (follow-up of 56,214 person-years), 707 cancers developed in 12,127 patients with ovarian cancer. The SIR for all cancers was 2.78 (95% confidence interval 2.58–3.00). SIRs for follow-up periods of >5, 1–5, and <1 year were 1.87, 2.04, and 6.40, respectively. After the exclusion of SPM occurring within 1 year of ovarian cancer diagnosis, SIRs were significantly higher for cancers of the colon, rectum, and anus (2.14); lung and mediastinum (1.58); breast (1.68); cervix (1.65); uterus (7.96); bladder (3.17), and thyroid (2.23); as well as for leukemia (3.98) and others (3.83). Multivariate analysis showed that age ≥ 50 years was a significant SPM risk factor (hazard ratio [HR] 1.60). Different treatments for ovarian cancer, including radiotherapy (HR 2.07) and chemotherapy (HR 1.27), had different impacts on SPM risk. Patients with ovarian cancer are at increased risk of SPM development. Age ≥ 50 years, radiotherapy, and chemotherapy are independent risk factors. Close surveillance of patients at high risk should be considered for the early detection of SPM. PMID:26402833

    Objective of this article is to appraise diagnostic aspects and treatment modalities in childhood ovarian tumor in background of available evidence. Literature search on Pubmed revealed various aspects of epidemiology, histopathological diagnosis, and treatment of pediatric ovarian tumor. 85 % of childhood tumors are germ cell tumors. The varied histopathological picture in germ cell tumors poses a diagnostic and therapeutic challenge. Immunohistochemistry and newer genetic markers like SALL4 and karyopherin-2 (KPNA2) have been helpful in differentiating ovarian yolk sac tumor from dysgerminoma, teratomas, and other pictures of hepatoid, endometrioid, clear cell carcinomatous, and adenocarcinomatous tissues with varied malignant potential. Before platinum therapy, these tumors were almost fatal in children. Fertility-conserving surgery with bleomycin, etoposide, and cisplatin has dramatically changed the survival rates in these patients. This modality gives cancer cure with healthy offspring to female patients with childhood ovarian tumor. Evidence also supports this protocol resulting in successful pregnancy rates and safety of cytotoxic drugs in children born to these patients. PMID:24757335

    Malignant Mixed Mullerian Tumour of the Ovary (OMMMT), also referred to as carcinosarcoma is a very rare tumour accounting for less than 1% of all ovarian cancers. Due to the rarity of OMMMT, little is known about the disease course and outcome of women with these tumours. It is important to evaluate because of its aggressive behaviour with extremely unfavourable prognosis. These tumours are composed of both malignant epithelial and mesenchymal elements. Current data in the literature is still limited to small case series and case reports, therefore, its optimal treatment is somewhat controversial. In the current report, we introduce a case of OMMMT which was successfully treated with Platinum-based combination chemotherapy after optimal cytoreductive surgery. The clinical manifestations, pathologic characteristics, diagnosis and management of these tumours are reviewed here. Although the most effective treatment is currently unknown, optimal cytoreductive surgery and platinum-based chemotherapy appears to improve the outcomes. Despite the aggressive nature of this tumour and its poor response to the treatment, management works best when cancer is found early. The stage of the disease is the most important prognostic factor. Therefore, the crucial question is how to diagnose the cancer at earlier stages rather than seeking the optimal treatment.

    Primary ovarian insufficiency (POI), also known as premature ovarian failure or premature menopause, is defined as cessation of menstruation before the expected age of menopause. Potential etiologies for POI can be divided into genetic, autoimmune, and iatrogenic categories. This review will try to summarize the genetic basis of POI focusing on recent data that are available using newer genetic techniques such as genome-wide association studies, whole-exome sequencing (WES), or next-generation sequencing techniques. By using these techniques, many genes have arisen that play some role in the pathophysiology of POI. Some of them have been replicated in other studies; however, the majority has not been proven yet to be unequivocally causative through functional validation studies. Elucidating the genetic and molecular basis of POI is of paramount importance not only in understanding ovarian physiology but also in providing genetic counseling and fertility guidance. Once additional variants are detected, it might become possible to predict the age of (premature) menopause in women at risk for POI. Women having certain perturbations of POI can be offered the option of oocyte cryopreservation, with later thawing and use in assisted reproductive technology at an appropriate age. PMID:27513024

    There has been reported increased incidence of ovarian tuberculosis in the tropics since the advent of HIV/AIDS disease. We report a case of bilateral ovarian tuberculosis associated with a single right kidney of uncertain origin in an immunocompetent 15-year-old generally healthy-looking girl. Abdominopelvic scan was equivocal about the diagnosis of the lesion as it failed to differentiate it from malignancy. Tuberculin and histopathology were necessary to confirm the diagnosis of ovarian tuberculosis. Antituberculous medical therapy successfully resolved the disease. PMID:26168758

    Only five cases of recurrence of malignant mixed Mullerian tumor (carcinosarcoma) from the ovarian carcinoma have been published in the literature to our knowledge. A 64-year-old woman first underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy because of pelvic mass. Histological diagnosis was serous papillary carcinoma of the left ovary. After six courses of chemotherapy, CA125 level returned to normal range. However, she had persistent multiple mediastinal and para-aortic lymphadenopathies in spite of additional six courses of chemotherapy. Then she underwent the second operation about 2 years after primary surgery. Multiple excisional biopsies were taken from subcutaneous tissue, over the bowels and the left external iliac artery. The histopathological diagnosis which was confirmed by immunohistochemical study was malignant mixed Mullerian tumor for all metastatic foci. A rare case of ovarian serous papillary carcinoma recurring as malignant mixed Mullerian tumor is reported. PMID:26713165

    Primary ovarian insufficiency is a condition that represents impaired ovarian function on a continuum with intermittent ovulation. This condition commonly leads to premature menopause, defined as cessation of ovulation prior to the age of 40 years. Because there are potential immediate and long-term consequences of hypoestrogenism, a timely diagnosis is invaluable. This comprehensive review will discuss identifiable causes for primary ovarian insufficiency, including genetic disorders and metabolic abnormalities, as well as review current strategies for diagnosis, evaluation, and management of women with this condition.

    Malignant melanomas (MM) of the oral cavity are extremely rare, accounting for 0.2% to 8.0% of all malignant melanomas. Malignant melanomas is more frequently seen at the level of the hard palate and gingiva. Early diagnosis and treatment are important for reducing morbidity. Malignant melanoma cells stain positively with antibodies to human melanoma black 45, S-100 protein, and vimentin; therefore, immunohistochemistry can play an important role in evaluating the depth of invasion and the location of metastases. A 76-year-old man developed an oral malignant melanoma, which was originally diagnosed as a bluish reactive denture hyperplasia caused by an ill-fitting lower denture. The tumor was removed surgically, and histopathological examination revealed a nodular-type MM. There was no evidence of recurrence over a 4-year follow-up period. PMID:27052289

    INTRODUCTION Primary malignant hepatic mesotheliomas are extremely rare. We report the case of a patient with primary intrahepatic malignant mesothelioma who was treated in our department. PRESENTATION OF CASE A 66-year old male patient was admitted to our department for the evaluation of anemia. An abdominal computed tomography scan revealed a large space occupying lesion in the right liver lobe. DISCUSSION The tumor was subsequently resected and a diagnosis of primary intrahepatic malignant mesothelioma was made after pathologic examination. The patient did not receive adjuvant therapy and is currently alive and free of disease, 36 months after the resection. CONCLUSION To our knowledge this is the eighth adult case of primary intrahepatic malignant mesothelioma reported in the literature. These tumors are rarely diagnosed preoperatively. Absence of previous asbestos exposure does not exclude malignant mesothelioma from the differential diagnosis. Proper surgical treatment may offer prolonged survival to the patient, without adjuvant therapy. PMID:25460485

    Chromosome abnormalities that are specific and recurrent may occur in regions of the genome that are involved in the conversion of normal cells to those with tumorigenic potential. Ovarian cancer is the primary cause of death among patients with gynecological malignancies. We have performed cytogenetic analysis of 16 ovarian tumors from women age 28-82. Three tumors of low malignant potential and three granulosa cell tumors had normal karyotypes. To look for the presence of trisomy 12, which has been suggested to be a common aberration in this group of tumors, interphase fluorescence in situ hybridization was performed on direct preparations from three of these tumors using a probe for alpha satellite sequences of chromosome 12. In the 3 preparations, 92-98 percent of the cells contained two copies of chromosome 12, indicating that trisomy 12 is not a universal finding in low grade ovarian tumors. Endometrioid carcinoma of the ovary is histologically indistinguishable from endometial carcinoma of the uterus. We studied 10 endometrioid tumors to determine the degree of genetic similarity between these two carcinomas. Six out of ten endometrioid tumors showed a near-triploid modal number, and one presented with a tetraploid modal number. Eight of the ten contained structural chromosome abnormalities, of which the most frequent were 1p- (5 tumors), 19q+ (3 tumors), 6q- or ins(6) (4 tumors), 3q- or 3q+ (4 tumors). These cytogenetic results resemble those reported for papillary ovarian tumors and differ from those of endometrial carcinoma of the uterus. We conclude that despite the histologic similarities between the endometrioid and endometrial carcinomas, the genetic abnormalities in the genesis of these tumors differ significantly.

    Thirty-two patients with malignant ovarian disease were referred after primary surgery to the Gynaecological Oncology Unit of Groote Schuur Hospital, Cape Town. All 32 patients underwent a re-laparotomy with a view to accurate staging and possible cytoreductive surgery. On referral, 24 patients (75%) had stage I or II disease and the remaining 8 patients (25%) had stage III and IV disease. Twenty-seven patients (81%) had ovarian malignant disease of epithelial origin while the remaining 5 patients (19%) had ovarian disease of nonepithelial origin. Five (20.8%) of a total of 24 patients with stage I or II disease had their disease stage raised after repeat laparotomy. The overall success rate of cytoreductive surgery, i.e. less than 2 cm residual disease, was 58%. PMID:1925822

    Purpose of Review Despite an incidence of one percent among women under the age of forty, primary ovarian insufficiency (POI) is still poorly understood. As the variable etiology and presentation of POI complicate its management, a standard regimen for treatment remains to be established. However, emerging research has provided new insight on current mainstays of treatment as well as novel management approaches and therapeutic interventions. Recent findings Recent clinical trials in women with POI indicate that the widely-used regimen of transdermal estradiol and medroxyprogesterone acetate restores bone mineral density (BMD) to a level equal to women with normal ovarian function. Further research verifies that compounded bioidentical hormones and androgen supplementation are inadequate in treating POI and lowering risk for long-term sequelae. Additionally, assessing changes in bone turnover markers may be useful for monitoring BMD. Alternative therapies such as acupuncture, DHEA, and buproprion may be effective in treating the effects of estrogen deficiency at some level, but require further investigation. Summary Recent updates show promise in improving management methods and reducing risk of long-term sequelae. Additional research that expands upon the most current literature is critical in order to achieve an evidence-based standard of best practice. PMID:26512773

    The present study reports two cases of large ovarian malignancy during pregnancy, which is very rare. The two patients were received between Nov 2012 and Feb 2013 at Gynecological and Obstetrical Department, Women’s Hospital, School of Medicine, Zhejiang University (People’s Republic of China). Both cases present tumor sized more than 20 cm, with one case of 40 cm. Both patients underwent timely cesarean section, with survival of the Child, and successful removal of the tumor. All patients showed good outcome in the follow-up period. Therefore the large ovarian malignancy during pregnancy could be well treated after careful clinical evaluation. PMID:25484595

    Bilateral malignant ovarian germ cell tumors (MOGCTs) are rare. Determination of the optimal treatment modalities is crucial, as these malignancies mainly affect girls and young women who may wish to preserve their fertility. In order to review the prevalence, clinical characteristics, treatment and outcome of bilateral MOGCTs, we performed a retrospective review of patients who were diagnosed with bilateral MOGCTs and underwent primary surgery at the Obstetrics and Gynecology Hospital of Fudan University (Shanghai, China) between January, 2001 and December, 2014. Of the 130 patients investigated, 8 were diagnosed with bilateral disease, most of whom were International Federation of Gynecology and Obstetrics stage I. There was no significant difference in overall and disease-free survival between patients with unilateral and those with bilateral disease. Cases with dysgerminoma, dysgerminoma coexisting with gonadoblastoma, yolk sac tumor and ovarian primary choriocarcinoma were included in this study. Fertility was spared in 2 patients (1 with dysgerminoma and 1 with ovarian primary choriocarcinoma). The patient with ovarian choriocarcinoma experienced relapse and was finally salvaged by radical surgery and adjuvant chemotherapy. According to our results and the published data, patients affected by bilateral MOGCTs have a satisfactory prognosis. The treatment modalities largely depend on the histological type of the tumor. Fertility-sparing surgery may be safe for patients affected by dysgerminoma, but should be considered with caution in patients with ovarian primary choriocarcinoma. PMID:27446585

    Primary malignant myelomatous pleural effusion (PMMPE) occurs in less than 1% of patients with multiple myeloma and is diagnosed either by visualization of plasma cells on cytology or by positive flow cytometry. The presence of immature plasma cells characterized by high nucleus to cytoplasm ratio, visible nucleolus and presence of Mott cells and Russell bodies are independent poor prognostic factors. The clinician should differentiate PMMPE from secondary pleural effusion as it is associated with a significantly worse prognosis and poor overall survival. PMID:27525090

    Patient: Female, 26 Final Diagnosis: Endosalpingiosis Symptoms: Chronic pelvic pain Medication: — Clinical Procedure: Diagnostic laproscopy (conservative management) Specialty: Obstetrics and Gynecology Objective: Challenging differential diagnosis Background: Interesting and unusual case of endosalpingiosis mimicking ovarian malignancy presentation. Case Report: A 26-year-old G0P0 white female presented to our office with chronic pelvic pain. On vaginal examination, a nontender mass in left the adnexal region was palpable. Transvaginal ultrasound showed a left ovarian cyst. Laparoscopy was performed, which revealed diffuse bilateral ovarian excrescences with unusual multiple studdings throughout the peritoneum and abdominal cavity. Due to a suspicion of malignancy, a biopsy specimen was obtained for frozen sectioning. The specimen proved to be consistent with benign papillary serous cystadenofibroma. Gross appearance was still suspicious for malignancy and therefore left paraovarian cystectomy was performed. Additional specimens showed ovarian adenofibroma and endosalpingiosis. The patient’s complaint of pelvic pain improved after laparoscopy. Due to diffuse presentation of endosalpingiosis in the peritoneum, serial CT scan of abdomen and pelvis at 6-month intervals was recommended. Conclusions: To our knowledge, this is an unusual case of a young, nulliparous female presenting with diffuse-presentation endosalpingiosis in the abdomen and peritoneum, which on gross examination was suspicious for malignancy. By following a conservative approach and performing serial CT scans, the patient will be clinically monitored. PMID:25180540

    Ovarian mucinous tumors with mural nodules are rare surface epithelial-stromal tumors. The mural nodules are divergent neoplasms that may be benign or malignant. The latter may be in the form of a sarcoma, carcinosarcoma, anaplastic carcinoma, or a variety of other recognized histotypes of carcinoma, which raises the question of whether malignant mural nodules represent a form of dedifferentiation in ovarian mucinous tumors or whether they represent collision tumors. We recently reported the K-RAS gene mutation status in a case of ovarian mucinous adenocarcinoma with mural nodule of high-grade sarcoma. The mucinous and sarcomatous components revealed a mutation in codon 12 of the K-RAS gene of a different nucleotide substitution, indicating that these 2 tumor components were different clones of the same tumor. Herein, we are reporting another case of a 20-yr-old woman who presented with 22 cm pelvic mass, omental caking, and ascites. A diagnosis of invasive mucinous carcinoma with mural nodules of anaplastic carcinoma was rendered. K-RAS gene mutation studies revealed p.G12V, c.35G>T mutation in the 2 components of the tumor, which is the most common mutation reported in mucinous tumors of the ovary. The fact that sarcomatous or anaplastic carcinomatous mural nodules in ovarian mucinous tumors display the same K-RAS mutations as their underlying mucinous neoplasms provides supportive evidence that at least some malignant mural nodules represent a form of dedifferentiation in ovarian mucinous tumors, rather than a collision of 2 divergent tumor types.

    After the implantation of ovarian tissue into the spleen of gonadectomized female Sprague-Dawley rats (splenic ovary), luteomata and later benign granulosa or granulosa-theca cell tumours develop. Treatment of these rats with 7,12 dimethylbenz(a)anthracene (DMBA), given intravenously, 2 mg/kg body weight weekly, total dosage 40 mg/kg, immediately and especially 25 weeks after implantation of ovarian tissue into the spleen, led to malignant, partially metastasizing granulosa, and in one case theca cell tumours, 16-46 weeks after beginning the carcinogen treatment. No malignant neoplastic growth was seen when diethylnitrosamine (DEN), 20 mg/kg once weekly for life, was injected subcutaneously immediately or 25 weeks after implanting ovarian tissue. Since the normal, non-implanted rat ovary was not affected by DMBA treatment the malignant transformation of splenic ovaries in the respective experimental groups may be related to the increased stimulation by pituitary gonadotrophins and formation of luteomata or beginning granulosa and theca cell proliferations.

  3. CXCL12 expression by healthy and malignant ovarian epithelial cells

    PubMed Central

    2011-01-01

    Background CXCL12 has been widely reported to play a biologically relevant role in tumor growth and spread. In epithelial ovarian cancer (EOC), CXCL12 enhances tumor angiogenesis and contributes to the immunosuppressive network. However, its prognostic significance remains unclear. We thus compared CXCL12 status in healthy and malignant ovaries, to assess its prognostic value. Methods Immunohistochemistry was used to analyze CXCL12 expression in the reproductive tracts, including the ovaries and fallopian tubes, of healthy women, in benign and borderline epithelial tumors, and in a series of 183 tumor specimens from patients with advanced primary EOC enrolled in a multicenter prospective clinical trial of paclitaxel/carboplatin/gemcitabine-based chemotherapy (GINECO study). Univariate COX model analysis was performed to assess the prognostic value of clinical and biological variables. Kaplan-Meier methods were used to generate progression-free and overall survival curves. Results Epithelial cells from the surface of the ovary and the fallopian tubes stained positive for CXCL12, whereas the follicles within the ovary did not. Epithelial cells in benign, borderline and malignant tumors also expressed CXCL12. In EOC specimens, CXCL12 immunoreactivity was observed mostly in epithelial tumor cells. The intensity of the signal obtained ranged from strong in 86 cases (47%) to absent in 18 cases (<10%). This uneven distribution of CXCL12 did not reflect the morphological heterogeneity of EOC. CXCL12 expression levels were not correlated with any of the clinical parameters currently used to determine EOC prognosis or with HER2 status. They also had no impact on progression-free or overall survival. Conclusion Our findings highlight the previously unappreciated constitutive expression of CXCL12 on healthy epithelia of the ovary surface and fallopian tubes, indicating that EOC may originate from either of these epithelia. We reveal that CXCL12 production by malignant

    Primary hepatic malignant melanoma is a very rare disease. In order to provide clues concerning diagnosis, differential diagnosis and pathogenesis of the disease, a case of a 49 year-old female patient with primary hepatic malignant melanoma is presented. B-mode ultrasound and Contrast-enhanced abdominal computerized tomography (CT) examinations revealed that nodules of varying sizes are diffusely distributed in her enlarged liver. Pathological examination revealed that tumor cells with poor differentiation were located in nests with prominent melanin deposition. Immuno-histochemical staining showed that the tumor cells were positive for HMB-45 and S-100 protein. No evidence for primary malignant melanoma of other sites had been found by comprehensive examinations. Therefore, the patient was diagnosed with primary malignant melanoma of liver. Our case showed that primary malignant melanoma of liver is of histological heterogeneity, and immunohistochemical staining may aid in differential diagnosis between it and other hepatic neoplasms.

    Ovarian malignant melanomas are extremely rare tumors. Most of them are secondary tumors and disseminated metastases are recognized at the time of diagnosis. Primary tumors are even more rare and usually associated with a teratoma. A 67-year-old female had a pelvic mass that was recognized on ultrasonography (USG) and physical examination. Intraoperative pathological consultation was reported as "pigmented solid ovarian tumor, probably compatible with malignant melanoma". Paraffin sections, and histochemical (Masson Fontana and Prussia blue) and immunohistochemical examination (S-100 and HMB-45) were also consistent with "malignant melanoma". This case was accepted as "Probably primary ovarian malignant melanoma" in lack of any other tumor focus on detailed clinical and radiological investigation, skin biopsies or pigmented lesions in medical history. It is reported for being an extremely rare tumor and its distinctive characteristics for differential diagnosis are emphasized. PMID:21630207

    Primary ovarian insufficiency (POI) occurs in about 1% of female population under the age of 40, leading to reproductive problems, an earlier encounter with menopausal symptoms, and complicated diseases. There are three presumable mechanisms involved in the development of POI, namely apoptosis acceleration, follicular maturation blocking and premature follicle activation, through the following studied causes: (i) chromosomal abnormalities or gene mutations: mostly involve X chromosome, such as FMR1 premutation; more and more potentially causal genes have been screened recently; (ii) metabolic disorders such as classic galactosaemia and 17-OH deficiency; (iii) autoimmune mediated ovarian damage: observed alone or with some certain autoimmune disorders and syndromes; but the specificity and sensitivity of antibodies towards ovary are still questionable; (iv) iatrogenic: radiotherapy or chemotherapy used in cancer treatment, as well as pelvic surgery with potential threat to ovaries' blood supply can directly damage ovarian function; (v) virus infection such as HIV and mumps; (vi) toxins and other environmental/lifestyle factors: cigarette smoking, toxins (e.g., 4-vinylcyclohexene diepoxide), and other environmental factors are associated with the development of POI. The etiology of a majority of POI cases is not identified, and is believed to be multifactorial. Strategies to POI include hormone replacement and infertility treatment. Assisted conception with donated oocytes has been proven to achieve pregnancy in POI women. Embryo cryopreservation, ovarian tissue cryopreservation and oocyte cryopreservation have been used to preserve ovarian reserve in women undergoing cancer treatments. PMID:22932883

    Ovarian malignant tumours are mostly ovarian cancers. The most frequent ovarian benign lesions are mature teratomas. A very rare ovarian neoplasm is carcinoid. It mostly occurs as a component of mature teratoma, what causes rare diagnosis before surgery. Study presents the case of patient with primary ovarian carcinoid in mature teratoma of one ovary, co-existing with primary epithelial carcinoma of another ovary. Surgical treatment of carcinoid involves adnexectomy or hysterectomy with adnexa and removal of great omenturn, followed by chemotherapy and radiotherapy. In young women with early-stage tumours, treatment can be limited to adnexectomy followed by close monitoring. In the presented case, management associated with the diagnosis of ovarian carcinoid, resulted in the detection of early-stage ovarian epithelial cancer. This case seems to confirm the recommendations to take tissue samples from the other ovary for histopathological evaluation in cases of ovarian unilateral benign tumours. PMID:26189263

    Ovarian mucinous tumors (OMTs) of the intestinal type share morphologic features with primary tumors of other sites, and it can often be difficult to distinguish primary ovarian from metastatic mucinous tumors. MUC1, MUC2, MUC5AC, and MUC6 expressions were studied by immunohistochemistry in 36 OMTs of intestinal type (17 malignant, 19 borderline), 18 pancreatic, 12 biliary, 15 esophageal, 9 gastric, and 7 colorectal/appendiceal adenocarcinomas. All samples were from primary sites, except for colorectal tumors which were from ovarian metastases. Borderline and malignant OMTs show similar mucin immunoprofile, being strongly and uniformly positive for MUC5AC (97.2% of cases), whereas only focally positive for MUC1 (19.4%), MUC2 (38.9%), and MUC6 (22.2%). The positive frequencies of pancreatic adenocarcinomas for MUC1, MUC2, MUC5AC, and MUC6, respectively, were 100%, 16.7%, 94.4%, and 61.1%; for biliary (cholangiocarcinomas) were 91.7%, 0%, 16.7%, and 8.3%; for esophageal carcinomas were 73.3%, 33.3%, 53.3%, and 26.7%; for gastric carcinomas were 44.4%, 44.4%, 44.4%, and 0% and for lower gastrointestinal tract cancers were 28.6%, 85.7%, 42.9%, and 0%. Our study shows that OMTs are usually MUC5AC+/MUC1-, which is different from pancreatic, biliary, esophageal, gastric, and colorectal/appendiceal carcinomas. We recommend that these mucin stains be added to the panel of immunostains to differentiate metastatic tumors to the ovary from primary OMTs. PMID:24487472

    Primary ovarian tumors are generally uncommon in rats used in toxicologic studies. A malignant Sertoli cell tumor was present in the ovary of a 19-week-old female Sprague Dawley rat. Macroscopically, the mass was white and firm, 10 × 13 × 17 mm in size, and located in the right ovary. Histopathologically, the mass was composed of nests of pleomorphic cells, which formed seminiferous-like tubules separated by a thin fibrovascular stroma. The tubules were lined by tumor cells, which had basally located nuclei and abundant eosinophilic and vacuolated cytoplasm. In some areas, the tumor cells were arranged in a retiform growth pattern, mimicking a rete testis/ovarii. Disseminated metastases to the surfaces of the mesentery, spleen and liver were also present. Immunohistochemically, many tumor cells were strongly positive for vimentin, estrogen receptor α and Ki 67. Some tumor cells were positive for pancytokeratin and inhibin α. These findings closely resemble those of an ovarian-derived human malignant Sertoli cell tumor. From our review of the literature, we believe this is the first report of a spontaneous malignant Sertoli cell tumor in the ovary of a young laboratory rat. This case might provide useful historical control information for rat toxicity studies. PMID:26989303

    The approval of the first specific drug catumaxomab for the treatment of malignant ascites is the subject of this review. This trifunctional antibody is known to kill EpCAM-positive tumor cells and therefore attacks the primary cause of malignant ascites formation in the peritoneal cavity. Until today catumaxomab is the only EpCam-targeted antibody approved by the European Medicines Agency. Ovarian cancer is caused by epithelial tumors cells which overexpress epithelial cell adhesion molecule (EpCAM). The existing literature concerning the use of catumaxomab for the treatment of malignant ascites associated with ovarian cancer until today is reported in this article. It is very encouraging that different prospective studies from diverse scientific teams recently presented positive results concerning the efficacy and the safety of catumaxomab in the treatment of malignant ascites in patients with ovarian cancer. A case of a patient with ovarian cancer FIGO IIIc is also referred in this article. A complete remission and stable disease was found after 4 i.p. infusions of catumaxomab. PMID:23644922

    Background: Differentiation between benign and malignant ovarian neoplasms is essential to create a system for patient referrals. Objectives: The aim of the present prospective trial was to analyze the value of the risk of ovarian malignancy algorithm (ROMA) in prediction of adnexal masses malignancy in pre- and post-menopause women before operation. Materials and Methods: Preoperative serum samples were tested for CA125 and HE4 using fully automated methods (Abbott architect) and gained best cutoff. The ROMA index was analyzed in 99 patients (including 68 pre-menopause and 31 menopause) with adnexal masses referred to Imam Hossein Hospital/Tehran/Iran and had been scheduled for operation. The pathological results showed 43 cases (22 menopause) with malignant adnexal masses and 56 cases (9 menopauses) with benign adnexal masses. Demographical data, clinical symptoms and the ROMA index were separately analyzed and contrasted in benign and malignant in both menopause and pre-menopause patients. Results: The only significant difference was the older age of the malignant group vs. benign group (P = 0.001) regarding demographic findings. As concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (P = 0.001). Additionally, data analysis of patients as a total group showed that specificity (96.4%), positive predictive value (PPV) (94.1%), area under the curve (AUC) (0.907), and diagnostic accuracy (DA) (86.9%) of the ROMA were higher than HE4 (91.1%, 85.7%, 0.857 and 81.8%. respectively) and CA125 (87.9%, 67.3%, 0.828 and 75.8%, respectively) alone. Besides, negative predictive value (NPV) (86.4%) and sensitivity (86.1%) of CA125 were higher than HE4 (79.7% and 69.8%, respectively). In contrast, specificity of HE4 (91.1%) was higher than CA125 (67.9%). Data analysis of patients as two groups (pre and post menopause groups) showed the same results.

The patient had undergone a closed vitrectomy because of chronic vitreous hemorrhage. Histocytology of the vitreous fluid specimens revealed melanoma cells of variable shape and size (from 30-150 microns) with eccentric nuclei. Many of these cells were binucleated or multinucleated with small, uniform, evenly dispersed intracytoplasmic melanin granules. The histocytologic findings together with the postoperative tumor characteristics by ultrasonography and fluorescein angiography suggested the diagnosis of choroidal malignant melanoma. PMID:3566022

    Purpose: To determine the incidence and risk factors for nonbreast second malignancies (NBSMs) in women after treatment for primary breast cancer. Methods and Materials: Between January 1985 and December 1995, a total of 1,084 breast cancer patients were analyzed for NBSMs. Detailed analysis was carried out for age, family history, disease stage, radiation therapy, chemotherapy, hormone therapy, other clinical/pathologic characteristics, and site of NBSMs. The Cox proportional hazard regression model was used to estimate the relative risk of NBSMs. Results: Median follow-up was 12 years. In total, 33 cases of NBSMs were noted in 29 patients. The overall incidence of NBSM was 3%, and the median time for NBSMs was 7 years. The most common NBSMs were gynecologic (22 patients), gastrointestinal (4 patients), head and neck (3 patients), hematologic (2 patients), lung (1 patient), and thyroid (1 patient). The NBSMs rate at 12 years was 2.4% for both mastectomy and radiation therapy groups. In the subset of patients less than 45 years of age at the time of treatment, the NBSMs rate was 0.7% as compared with 4.6% in patients more than 45 years of age (p = 0.001). Statistically significant higher incidences of endometrial and ovarian cancer were seen in patients with hormonal therapy (5.2%) as compared with patients without hormonal therapy (1.8%, p = 0.002). Women with a family history of breast cancer had a higher incidence (6%) of endometrial and ovarian malignancy compared with women without such a history (2.1%, p = 0.003). Chemotherapy did not affect the risk of second malignancy. Conclusion: The most common NBSMs in this study were gynecologic. Family history of breast cancer was a high risk factor for NBSMs. No risk of NBSMs with radiotherapy was observed.

    Objective We sought to determine the validity of cancer antigen 125 (CA-125) and the risk of malignancy index (RMI) in the diagnosis of ovarian cancer in women presenting with adnexal lesions of various histopathology types. Methods This retrospective cross- sectional study included all women with adnexal lesions who were evaluated at the Royal Hospital, Oman, between January 2012 and December 2014. The inclusion criteria included women who underwent surgical intervention and who had preoperative CA-125 testing and pelvic ultrasound in the work-up plan of their management. The surgical intervention was usually followed by a histopathological diagnosis of the nature of the lesion, which was used as the gold standard for the evaluation of both CA-125 and RMI. Results The cohort included 361 women who had serum CA-125 and pelvic ultrasound prior to the surgical intervention of the adnexal lesion. Of these women, 61 (17%) had malignant ovarian lesions. Using the proposed cut-off 35 U/ml for CA-125 and 200 for RMI, the CA-125 test was more sensitive for detecting the majority of malignant ovarian tumors compared to the RMI (69% vs. 57%). Both tests were more sensitive in detecting epithelial ovarian cancer compared to other ovarian cancers. However, RMI was more specific in excluding benign ovarian lesions compared to CA-125 (81% vs. 68%). Additionally, RMI had a better area under the curve compared to CA-125 (0.771 vs. 0.745; p<0.005). Lowering the RMI cut-off to 150 resulted in a better sensitivity (62% vs. 57%) and had an acceptable specificity (78% vs. 81%) compared to a cut-off of 200. Conclusion Both CA-125 and RMI have good validity in the diagnosis of ovarian tumors. CA-125 has higher sensitivity; however, RMI has higher specificity. In combination, CA-125 might be more valid for the diagnosis of malignant ovarian cancer while RMI is more valid for excluding the diagnosis of these tumors. Differential use of these two tools will improve the triage of women with

    Objective To estimate the incidence of falsely elevated risk of ovarian malignancy algorithm (ROMA) in a group of women with pathologically confirmed endometrioma and to investigate the associated factors. Methods One hundred premenopausal women surgically diagnosed with ovarian endometrioma were selected. Preoperative clinical, laboratory, and surgical characteristics were compared between the elevated-risk group (ROMA-premenopausal value, ≥7.4%) and normal-risk group (ROMA-premenopausal value, <7.4%). Results Elevated ROMA was observed in 15 women (false positive rate, 15%). Excluding one woman with known chronic renal failure, we compared the characteristics of 99 women between the elevated-risk group (n=14) and the normalrisk group (n=85). None of the clinical and surgical variables distinguished the two groups. Serum level of CA 125 >82.3 U/mL and serum level of human epididymis protein 4 (HE4) >46 pmol/L could predict an elevated ROMA test with a statistical significance. When serum level of HE4 ≤46 pmol/L, none of the women showed an elevated ROMA test, regardless of serum level of CA 125; however, 55.6% of the women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 ≤82.3 U/mL and all women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL. Conclusion The incidence of falsely elevated ROMA was 15% in the group of women with pathologically confirmed endometrioma. Interpretation of the ROMA results should be cautious when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL in women with suspicious ovarian endometrioma. PMID:27462596

    About 90% of malignant tumors of the ovary in Scandinavia develop from the germinal epithelium. There are great differences in the incidence rates between countries in the Western world and in Africa and Asia. The WHO classification of ovarian malignancies is generally used. The epithelial tumors comprise the serous, mucinous, endometrioid, clear cell, undifferentiated and mixed true carcinomas. In addition, borderline lesions of especially the serous and mucinous types are of interest when the question of preservation of ovarian function comes into notice. Conservative surgery, which means removal of only the afflicted ovary should be restricted to young women of the childbearing age who want to preserve the possibility of becoming pregnant. However, certain prerequisites must be fulfilled. The tumor must be located to one ovary only (Stage Ia) and must be either a borderline lesion or a Grade 1 true carcinoma of either the serous, mucinous or endometrioid type. There must be no ascites and peritoneal washings must be negative for cancer cells. Germ cell tumors are usually found in young women. Only the dysgerminomas are regularly bilateral in 10-15% of the cases. All other germ cell tumors are rarely bilateral. But both in borderline lesions, Grade 1 true carcinomas, and in germ cell tumors, a biopsy of the normal looking contralateral ovary should always be performed. Endodermal sinus tumors and immature teratomas may well be treated conservatively by surgery, but modern triple chemotherapy (VAC, PVB) must be added. Granulosa theca cell tumors are bilateral in only about 5% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2824278

    The tumor formation may be the earliest manifestation preceeding other symptoms, signs and bone marrow evidence of systemic malignancy - leukemia/lymphoma. Here we present three cases of systemic malignancy in which bone lesions were the first manifested signs of the disease. All three cases were thought to be orthopedic cases and had been treated as so without genuing improvement. We would like to draw an attention to children who present with multifocal musculoskeletal pain and the importance of whole-body scaning. We describe interesting cases of diffuse large cell lymphoma and leukemia that initially presented as primary osteolytic bone lesion and discuss the differential diagnosis, literature review of non-Hodgkin's lymphoma arising in bone as the primary site (Tab. 1, Fig. 3, Ref. 18).

    A 59-year-old male patient had 5-month history of gait disturbance and memory impairment. His initial brain computed tomography scan showed 3.5×2.8 cm sized mass with high density in the pineal region. The tumor was hypointense on T2 weighted magnetic resonance images and hyperintense on T1 weighted magnetic resonance images with heterogenous enhancement of central portion. The tumor was totally removed via the occipital transtentorial approach. Black mass was observed in the operation field, and after surgery, histopathological examination confirmed the diagnosis of malignant melanoma. Whole spine magnetic resonance images and whole body 18-fluoro-deoxyglucose positron emission tomography could not demonstrate the primary site of this melanoma. Scrupulous physical examination of his skin and mucosa was done and dark pigmented lesion on his left leg was found, but additional studies including magnetic resonance images and skin biopsy showed negative finding. As a result, final diagnosis of primary pineal malignant melanoma was made. He underwent treatment with the whole brain radiotherapy and extended local boost irradiation without chemotherapy. His preoperative symptoms were disappeared, and no other specific neurological deficits were founded. His follow-up image studies showed no recurrence or distant metastasis until 26 weeks after surgery. Primary pineal malignant melanomas are extremely rare intracranial tumors, and only 17 cases have been reported since 1899. The most recent case report showed favorable outcome by subtotal tumor resection followed by whole brain and extended local irradiation without chemotherapy. Our case is another result to prove that total tumor resection with radiotherapy can be the current optimal treatment for primary malignant melanoma in the pineal region. PMID:25628812

    Ovarian cancer is the most lethal gynecologic malignancy worldwide, and the survival rates have remained low in spite of medical advancements. More research is dedicated to the identification of novel biomarkers for this deadly disease. The association between ARMc8 and ovarian cancer remained unraveled. In this study, immunohistochemical staining was used to examine ARMc8 expression in 247 cases of ovarian cancer, 19 cases of borderline ovarian tumors, 41 cases of benign ovarian tumors, and 9 cases of normal ovarian tissues. It was shown that ARMc8 was predominantly located in the cytoplasm of tumor cells, and its expression was up-regulated in the ovarian cancer (61.9%) and the borderline ovarian tumor tissues (57.9%), in comparison with the benign ovarian tumors (12.2%; P < .05) and the normal ovarian tissues (11.1%; P < .05). In ovarian cancer, ARMc8 expression was closely related to International Federation of Gynecology and Obstetrics stages (P = .002), histology grade (P < .001), lymph node metastasis (P = .008), and poor prognosis (P < .001). Univariate and multivariate Cox analyses revealed that ARMc8 expression was an independent prognostic factor for ovarian cancer (P = .039 and P = .005). In addition, ARMc8 could promote the invasion and migration of ovarian cancer cells. Overexpressing ARMc8 enhanced the invasion and metastasis capacity of ARMc8-low Cavo-3 cells (P < .001), whereas interfering ARMc8 significantly reduced cell invasion and metastasis in ARMc8-high SK-OV-3 cells (P < .001). Furthermore, ARMc8 could up-regulate matrix metalloproteinase-7 and snail and down-regulate α-catenin, p120ctn, and E-cadherin. Collectively, ARMc8 may enhance the invasion and metastasis of ovarian cancer cells and likely to become a potential therapeutic target for ovarian cancer. PMID:26232863

    The clinical and radiological findings in 19 patients with primary duodenal malignancy are described. Weight loss, abdominal pain, nausea and vomiting were the main symptoms. Diagnosis was made by endoscopy or ERCP (71%) or by barium studies (68%). In retrospect the tumour was visible in 97% of the studies. Tumour growth was longitudinal, circular or spiral, the inner curvature being involved over a greater length than the outer curvature. Exophytic tumour growth, involvement of the papilla of Vater, malignant spikes, transient, non-constant tumour image, skip lesions and ulceration were often seen. Mean survival time was 18 months from start of symptoms in 10 inoperable patients, and 24 months in 9 patients undergoing resection. PMID:2986213

    Ovarian cancer is the most frequent cause of death from gynaecological malignancies world wide. Little improvement has been made in the long-term outcome of this disease, with the 5-year survival of patients only 30%. This poor prognosis is due to the late presentation of the disease and to the unpredictable response of ovarian cancer to chemotherapy. The cytochrome P450 enzymes are a superfamily of haemoproteins, known to be involved in the metabolic activation and/or detoxification of a number of anti-cancer drugs. CYP1B1 is a tumour-related form of cytochrome P450 which is over expressed in a wide variety of primary tumours of different histological type. The presence of CYP1B1 may be of importance in the modulation of these tumours to anti-cancer drugs. We have conducted a comprehensive immunohistochemical investigation, into the presence of cytochrome P450 CYP1B1 in primary and metastatic ovarian cancer. The key findings of this study are the increased expression of CYP1B1 in the majority of ovarian cancers investigated (92%), with a strong correlation demonstrated between CYP1B1 expression in both primary and metastatic ovarian cancer (P= 0.005 Spearman's rank correlation test). In contrast no detectable CYP1B1 was found in normal ovary. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11461084

    Loss of heterozygosity data from familial tumors suggested that BRCA1, a gene that confers susceptibility to ovarian and early-onset breast cancer, encodes a tumor suppressor. The BRCA1 region is also subject to allelic loss in sporadic breast and ovarian cancers, an indication that BRCA1 mutations may occur somatically in these tumors. The BRCA1 coding region was examined for mutations in primary breast and ovarian tumors that show allele loss at the BRCA1 locus. Mutations were detected in 3 of 32 breast and 1 of 12 ovarian carcinomas; all four mutations were germline alterations and occurred in early-onset cancers. These results suggest that mutation of BRCA1 may not be critical in the development of the majority of breast and ovarian cancers that arise in the absence of a mutant germline allele.

    BACKDROUND: Ovarian carcinoma is a leading cause of death in gynecological malignancy. Ovarian surface epithelial serous and mucinous tumours are classified as benign, borderline, and malignant. The identification of borderline tumours most likely to act aggressively remains an important clinical issue. AIM: This work aimed to study DNA ploidy and nuclear area in ovarian serous and mucinous; benign, borderline and malignant tumours. MATERIAL AND METHODS: This study included forty ovarian (23 serous and 17 mucinous) tumours. Paraffin blocks were sectioned; stained with haematoxylin and eosin for histopathologic and morphometric studies and with blue feulgen for DNA analysis. RESULTS: All four serous and six out of nine mucinous benign tumours were diploid. All eight serous and five mucinous malignant tumours were aneuploid. Nine of eleven (81.8%) serous and all three mucinous borderline tumours were aneuploid. There were highly significant differences in mean aneuploid cells percentage between serous benign (1.5%), borderline (45.6%) and malignant (74.5%) (p = 0.0001) and between mucinous benign (13.2%) and both borderline (63.7%) and malignant (68.4%) groups (p = 0.0001). There were significant differences in nuclear area between serous benign (26.191%), borderline (45.619%) and malignant (67.634 %) and a significant positive correlation between mean percentage aneuploid value and mean nuclear area in all serous and mucinous groups. CONCLUSION: We suggest that DNA ploidy and nuclear area combined, may be adjuncts to histopathology; in ovarian serous and mucinous benign, borderline and malignant neoplasms; identifying the aggressive borderline tumours.

    This is a retrospective review of 11 cases of primary malignant neoplasm of the female urethra seen at the Louisiana State University Medical Center in Shreveport from 1951 to 1984. The disease was relatively more frequent in the 60- to 79-year age-group. Squamous cell carcinoma was the most common among the different observed histopathology. A modified clinical staging system is introduced. At diagnosis, eight of 11 subjects (73%) had locally extensive disease. The majority of the patients were treated with radiotherapy alone or in combination with surgery. The overall severe complication rate was low. The poor results (20% local control and survival) obtained in this small experience suggest that perhaps a study using promising adjuvant chemotherapeutic agents is warranted. A literature review summary of reported radiotherapy results is included.

    Metastatic tumours of pleura are the most common malignant tumours causing malignant pleural effusion. Lungs are the most common primary sites. Primary pleural tumours are rarely seen and diffuse malignant mesothelioma is the most common malignant tumour of pleura. Primary malignant neuroendocrine tumour of pleura is not reported in the literature. Here, we report a rare case of primary malignant neuroendocrine tumour of pleura in a fifty-two-year-old, nonsmoker female who presented with right-sided pleural effusion and ipsilateral, dull aching chest pain. Clinical presentations of inflammatory lesions like tuberculous pleuritis and benign and malignant neoplasms of pleura are indistinguishable; hence, fluid cytology, pleural biopsy, and immunohistochemistry are necessary for exact tissue diagnosis of the tumours, which is mandatory for correct treatment and prognostic assessment.

    Colorectal adenocarcinoma is the second cause of cancer-related deaths in the United States. The occurrence of squamous cell carcinoma in the colorectum is extremely unusual. Malignant transformation from mature cystic teratoma of the ovary is a rare event. The most common transformation is squamous cell carcinoma, followed by adenocarcinoma. It occurs more often in elderly patients, who usually present with advance disease. We report two unusual cases of postmenopausal women diagnosed with squamous cell carcinoma in colon biopsies. After surgical resections, the carcinoma was proven to be the result of malignant transformation of ovarian mature cystic teratomas. Since squamous cell carcinoma of the colorectum is extremely rare, the presence of squamous cell carcinoma in a colonic biopsy in a female patient should alert the clinicians to other possible primary sites, as seen in these cases.

    Data from the Cancer and Steroid Hormone Study, a multicenter, population-based, case-control study were used to identify risk factors for epithelial ovarian cancer according to tumor behavior, histologic types, as well as p53 expression. Cases were women between 20 to 54 years old diagnosed with epithelial ovarian cancer from 1980 to 1982. Controls were women selected by random digit dialing. Tumor samples were analyzed for p53 overexpression using immunohistochemistry. Case-case and case-control conditional logistic regression models matched on age and diagnosing centers were used to calculate odds ratios (OR's) and 95% confidence intervals (CI's) for borderline, malignant, mucinous, and nonmucinous tumors, and p53 positive and p53 negative cases. The OR's for high number of lifetime ovulatory cycles (376-533 compared with less than 234) were 3.1 (95% CI 1.6-6.1) for malignant and 1.4 (95% CI 0.5-3.7) for borderline cases. The high number of ovulatory cycles was also a strong risk factor among nonmucinous cases. OR's for current and recent ex-smokers compared with never smokers were 2.8 (95% CI 1.7-4.8) for mucinous and 0.9 (95% CI 0.7-1.1) for nonmucinous types. Infertility showed a positive association with borderline ovarian cancer. Family history of ovarian or breast cancer was positively associated with malignant and nonmucinous cases. Parity had an inverse association with malignant ovarian cancer cases. When cases were subdivided by p53 results, the OR for tobacco smoking and p53 positive ovarian cancer was elevated for mucinous (OR = 3.9; 95% CI 0.8-18) at localized stage. Alcohol use showed a positive association with p53 positive malignant cases at advanced stage (OR = 2.0; 95% CI 1.2-3.2) and with p53 positive nonmucinous cases at advanced stage (OR = 2.1; 95% CI 1.2-3.4). A positive association between high number of ovulatory cycles and p53 positive malignant cases was observed in cases with localized stage (OR = 6.6; 95% CI 1.0-45) and advanced

  3. Platelets are associated with xenograft tumor growth and the clinical malignancy of ovarian cancer through an angiogenesis-dependent mechanism.

    Platelets are known to facilitate tumor metastasis and thrombocytosis has been associated with an adverse prognosis in ovarian cancer. However, the role of platelets in primary tumour growth remains to be elucidated. The present study demonstrated that the expression levels of various markers in platelets, endothelial adherence and angiogenesis, including, platelet glycoprotein IIb (CD41), platelet endothelial cell adhesion molecule 1 (CD31), vascular endothelial growth factor (VEGF), lysyl oxidase, focal adhesion kinase and breast cancer anti‑estrogen resistance 1, were expressed at higher levels in patients with malignant carcinoma, compared with those with borderline cystadenoma and cystadenoma. In addition, the endothelial markers CD31 and VEGF were found to colocalize with the platelet marker CD41 in the malignant samples. Since mice transplanted with human ovarian cancer cells (SKOV3) demonstrated elevated tumor size and decreased survival rate when treated with thrombin or thrombopoietin (TPO), the platelets appeared to promote primary tumor growth. Depleting platelets using antibodies or by pretreating the cancer cells with hirudin significantly attenuated the transplanted tumor growth. The platelets contributed to late, but not early stages of tumor proliferation, as mice treated with platelet‑depleting antibody 1 day prior to and 11 days after tumor transplantation had the same tumor volumes. By contrast, tumor size in the early TPO‑injected group was increased significantly compared with the late TPO‑injected group. These findings suggested that the interplay between platelets and angiogenesis may contribute to ovarian cancer growth. Therefore, platelets and their associated signaling and adhesive molecules may represent potential therapeutic targets for ovarian cancer. PMID:25502723

    Ovarian malignant germ cell tumors (OMGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad. OMGCTs are rare, accounting for about 2.6% of all ovarian malignancies, and typically manifest in adolescence, usually with abdominal pain, a palpable mass, and elevated serum tumor marker levels, which may serve as an adjunct in the initial diagnosis, monitoring during therapy, and posttreatment surveillance. Dysgerminoma, the most common malignant germ cell tumor, usually manifests as a solid mass. Immature teratomas manifest as a solid mass with scattered foci of fat and calcifications. Yolk sac tumors usually manifest as a mixed solid and cystic mass. Capsular rupture or the bright dot sign, a result of increased vascularity and the formation of small vascular aneurysms, may be present. Embryonal carcinomas and polyembryomas rarely manifest in a pure form and are more commonly part of a mixed germ cell tumor. Some OMGCTs have characteristic features that allow a diagnosis to be confidently made, whereas others have nonspecific features, which make them difficult to diagnose. However, imaging features, the patient's age at presentation, and tumor markers may help establish a reasonable differential diagnosis. Malignant ovarian germ cell tumors spread in the same manner as epithelial ovarian neoplasms but are more likely to involve regional lymph nodes. Preoperative imaging may depict local extension, peritoneal disease, and distant metastases. Suspicious areas may be sampled during surgery. Because OMGCTs are almost always unilateral and are chemosensitive, fertility-sparing surgery is the standard of care. PMID:24819795

    The expression of mRNA for the epidermal growth factor (EGF) receptor, EGF and transforming growth factor alpha (TGF-alpha) was determined in 76 malignant, six borderline and 15 benign primary ovarian tumours using the reverse transcriptase-polymerase chain reaction and related to clinical and pathological parameters. Of the malignant tumours, 70% (53/76) expressed EGF receptor mRNA, 31% (23/75) expressed EGF mRNA and 35% (26/75) expressed TGF-alpha mRNA. For the borderline tumours, four of six (67%) expressed EGF receptor mRNA, 1/6 (17%) expressed TGF-alpha mRNA and none expressed EGF mRNA. Finally, 33% (5/15) of the benign tumours expressed EGF receptor mRNA, whereas 40% (6/15) expressed EGF mRNA and 7% (1/15) expressed TGF-alpha mRNA. The presence of the EGF receptor in malignant tumours was associated with that of TGF-alpha (P = 0.0015) but not with EGF (P = 1.00), whereas there was no relationship between the presence of EGF and TGF-alpha (P = 1.00). EGF receptor mRNA expression was significantly and positively associated with serous histology (P = 0.006) but not with stage or grade. Neither EGF nor TGF-alpha showed any link with histological subtype or stage. The survival of patients with malignant tumours possessing EGF receptor mRNA was significantly reduced compared with that of patients whose tumours were negative (P = 0.030 for all malignant tumours; P = 0.007 for malignant epithelial tumours only). In contrast, neither the expression of TGF-alpha nor EGF was related to survival. These data suggest that the presence of EGF receptor mRNA is associated with poor prognosis in primary ovarian cancer. Images Figure 1 PMID:8562334

    Malignant melanoma of esophagus is usually a metastatic tumour rather than a primary tumour. Primary malignant melanoma accounts for less than 0.2% of all esophageal neoplasm. We report a case of primary spindle cell malignant melanoma of esophagus in a 69-year-old male who presented with history of dysphagia since 1 month. Radiological examinations revealed polypoidal growth at lateral aspect of esophagus. Biopsy was reported as grade III squamous cell carcinoma. Video assisted thoracoscopic esophagectomy was performed. Histopathological examination along with immunohistochemistry gave confirmed diagnosis of primary spindle cell malignant melanoma of esophagus. Though a rare entity, due to its aggressive nature and poor prognosis primary malignant melanoma should be one of the differential diagnoses in a patient with polypoidal esophageal mass lesion. Despite radical surgical treatment prognosis is extremely poor. PMID:27042502

    2014-07-01

    During recent years paramount changes have occurred in the pathogenesis of ovarian cancer and recent clinical studies identified new prognostic factors. Consequently, the FIGO has established a new staging system collectively covering carcinomas derived from the ovaries, the fallopian tubes and primary peritoneal cancers as well as malignant ovarian germ cell and sex-cord stromal tumors. The new staging system started on 01 January 2014. Major changes occurred in the FIGO IC/T1c stage with surgical spill (FIGO IC1/T1c1) versus capsule ruptured before surgery or tumor on ovarian or fallopian tube surface (FIGO IC2/T1c2) versus malignant cells in the ascites or peritoneal washings (FIGO IC3/T1c3). The regional lymph node metastases were subcategorised using a cut-off value of 10 mm as the largest dimension of the metastatic deposits. Distant metastases (excluding peritoneal metastases) were substaged as FIGO IVA/M1a in cases of cytologically or histologically proven pleural involvement and as FIGO IVB/M1b in cases of parenchymal metastases and metastases in extra-abdominal organs (including lymph nodes outside the peritoneal cavity and the inguinal lymph nodes).

    There is evidence that endometriosis as well as drugs used in the process of in vitro fertilisation appear to associate with increased risk for gynaecological cancer. In this review, we attempt to describe this relationship according to the most recent epidemiologic data and to present the possible mechanisms on the molecular level that could potentially explain this correlation. There are data to support that ovarian endometriosis could have the potential for malignant transformation. Epidemiologic and genetic studies support this notion. It seems that endometriosis is associated with specific types of ovarian cancer (endometrioid and clear cell). There is no clear association between endometriosis and breast or endometrial cancer. More studies are needed to establish the risk factors that may lead to malignant transformation of this condition and to identify predisposed individuals who may require closer surveillance. Currently, there is no proven relationship between any type of gynaecological cancer and drugs used for infertility treatment. In principle, infertile women have increased risk for gynaecologic malignancies. Nulligravidas who received treatment are at increased risk for malignancy compared with women who had conceived after treatment. There is limited evidence that clomiphene citrate use for more than six cycles or 900mg or treatment of women over the age of 40 could increase their risk for ovarian and breast cancer. More studies with the appropriate statistical power and follow-up time are required to evaluate accurately the long-term effects of these drugs and procedures. PMID:19733123

    Mature cystic teratomas are common ovarian germ cell tumors that rarely undergo malignant transformation, and intraoperative consultation is generally not warranted. The aims of this study were to review a large number of ovarian teratomas (OTs), to document the rate and histotypes of associated malignancy, and to identify parameters that may be associated with malignancy. In this study, a retrospective medical record review of patients diagnosed as having OTs from 2002 to 2011 was performed. Patient age, tumor size, type, and laterality were obtained from pathology reports and operative notes. A total of 956 OTs that ranged in size from 0.3 to 45 cm were identified. Intraoperative consultation was requested in a total of 316 (33.1%) of 956. Intraoperative gross evaluation only was performed on 211 (66.8%) of 316, of which 4 cases were malignant on final diagnosis. Frozen section was performed on 105 (33.2%) of 316, of which 12 were malignant on final diagnosis. The final diagnoses of all OT cases were as follows: 26 (2.7%) of 956 were associated with malignant tumors. The latter were larger than benign cases (average sizes, 11.2 cm vs 6.5 cm; P < .001), and patients with malignant tumors were significantly older than those with benign mature cystic teratoma (48.7 years vs 38.8 years, P < .001). The sensitivity and positive predictive value of frozen section examination during the intraoperative consultation for the detection of malignancy in OTs are 80% and 100%, respectively. In conclusion, patient age and large tumor size were associated with malignancy in this data set. Mucinous and serous borderline tumors were more common than squamous cell carcinoma in our cohort.

    2004-01-01

    Background Major issues in surgery for advanced ovarian cancer remain unresolved. Existing treatment guidelines are supported by a few published reports and fewer prospective randomized clinical trials. Methods We reviewed published reports on primary surgical treatment, surgical expertise, inadequate primary surgery/quality assurance, neoadjuvant chemotherapy, interval debulking, and surgical prognostic factors in advanced ovarian cancer to help resolve outstanding issues. Results The aim of primary surgery is a well-planned and complete intervention with optimal staging and surgery. Surgical debulking is worthwhile as there are further effective treatments available to control unresectable residual disease. Patients of gynecologic oncology specialist surgeons have better survival rates. This may reflect a working 'culture' rather than better technical skills. One major problem though, is that despite pleas to restrict surgery to experienced surgeons, specialist centers are often left to cope with the results of inadequate primary surgical resections. Patients with primary chemotherapy or those who have had suboptimal debulking may benefit from interval debulking. A proposal for a better classification of residual tumor is given. Conclusions Optimal surgical interventions have definite role to play in advanced ovarian cancers. Improvements in surgical treatment in the general population will probably improve patients' survival when coupled with improvements in current chemotherapeutic approaches. PMID:15461788

    The primary origin of some ovarian mucinous tumors may be challenging to determine, because some metastases of extraovarian origin may exhibit gross, microscopic, and immunohistochemical features that are shared by some primary ovarian mucinous tumors. Metastases of primary colorectal, appendiceal, gastric, pancreatic, and endocervical adenocarcinomas may simulate primary ovarian mucinous cystadenoma, mucinous borderline tumor, or mucinous adenocarcinoma. Recently, immunohistochemical expression of SATB2, a transcriptional regulator involved in osteoblastic and neuronal differentiation, has been shown to be a highly sensitive marker of normal colorectal epithelium and of colorectal adenocarcinoma. SATB2 expression has not been reported in normal epithelium of the female reproductive tract. Therefore, we hypothesized that SATB2 may be of value in distinguishing ovarian metastases of colorectal adenocarcinoma from primary ovarian mucinous tumors and from primary ovarian endometrioid tumors. Among primary ovarian tumors, SATB2 staining was observed in 0/22 mucinous cystadenomas that lacked a component of mature teratoma, 4/12 mucinous cystadenomas with mature teratoma, 1/60 mucinous borderline tumors, 0/17 mucinous adenocarcinomas, 0/3 endometrioid borderline tumors, and 0/72 endometrioid adenocarcinomas. Among ovarian metastases, SATB2 staining was observed in 24/32 (75%) colorectal adenocarcinomas; 8/10 (80%) low-grade appendiceal mucinous neoplasms; and 4/4 (100%) high-grade appendiceal adenocarcinomas. No SATB2 staining was observed in any ovarian metastasis of pancreatic, gastric, gallbladder, or endocervical origin. Evaluation of primary extraovarian tumors showed the highest incidences of SATB2 staining among primary colorectal adenocarcinomas (71%), primary appendiceal low-grade mucinous neoplasms (100%), and primary appendiceal high-grade adenocarcinomas (100%). Similar to their metastatic counterparts, none of the primary pancreatic or gastric

    Cyclin D1 is a cell cycle regulator of G1 progression that has been suggested to play a relevant role in the pathogenesis of several human cancer types. In the current study, the expression of cyclin D1 has been investigated in a series of 33 patients, with benign (10 patients), borderline (five patients) and malignant (18 patients) ovarian disease. Cyclin D1 protein and mRNA content were analysed by Western blotting and reverse transcriptase polymerase chain reaction respectively. The levels of cyclin D1 protein were undetectable in patients with benign disease, detectable in the majority of patients with borderline disease and elevated in those with ovarian carcinomas, being significantly related to the degree of malignancy (carcinoma vs benign, P = 0.0001; benign vs borderline, P = 0.0238). A significant relationship between cyclin D1 expression and tumour proliferative activity was also found (P = 0.000001). Moreover, eight benign lesions, two borderline tumours and 11 carcinomas proved to be suitable for the analysis of cyclin D1 transcript, and emerging data demonstrated significant agreement between protein abundance and mRNA expression. Results from the current study suggest that cyclin D1 expression is associated with the degree of transformation and most probably plays a role in the early development of ovarian malignancy.

    Objective: We conducted a case-control study to evaluate the diagnostic values of computed tomography (CT) and diffusion-weighted magnetic resonance imaging (DW-MRI) in differentiating malignancies from benign ovarian tumors and a meta-analysis to further confirm our results on DW-MRI. Methods: Totally 64 patients pathologically confirmed as ovarian cancer were included in this study. CT scan and DWI-MRI were performed and analyzed to get compared with pathological results, thereby assessing their accuracy, sensitivity and specificity. Meta-analysis was conducted by database searching and strict eligibility criteria, using STATA 12.0 (Stata Corp, College Station, TX, USA) software. Results: The accuracy, sensitivity, specificity, positive predictive value and negative predictive value for diagnosis of ovarian cancer in CT were 81.82%, 84.48%, 76.67%, 87.50% and 71.88%, respectively; those in DW-MRI were 89.77%, 93.10%, 83.33%, 91.53% and 86.21%, respectively. The Kappa coefficient of DW-MRI (K = 0.771) compared with pathological results was higher than CT (K = 0.602). The average apparent diffusion coefficient values of DW-MRI in diagnosis of benign and malignant ovarian tumors suggested statistically significant difference (1.325 ± 0.269×10-3 mm2/s vs. 0.878 ± 0.246×10-3 mm2/s, P < 0.001). Meta-analysis results showed that the combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of DW-MRI in discriminating benign versus malignant ovarian tumors were 0.93, 0.88, 7.70, 0.08 and 101.24, respectively. The area under the summary receiver operating characteristic curve was 0.95. Conclusions: Both CT and DW-MRI were of great diagnostic value in differentiating malignancies from benign ovarian tumors, while DW-MRI was superior to CT with higher accuracy, sensitivity and specificity.

    Melanoma of the oral cavity is a rare malignant disease. On account of the presence at relatively obscure areas in the oral cavity, most of oral malignant melanomas are diagnosed at a late stage. Early diagnosis is essential for successful treatment and perhaps is the key factor in improving the prognosis of oral malignant melanoma. However, no large clinical series exist, and in fact, clinical cases are the sole key source of information. We hereby present a series of four cases of primary oral malignant melanoma of South-East Asian ethnic origin, with long-term, regular follow-up. The age of the patients ranged between 40 and 70 years, with equal sex predilection, and the gingiva was found to be the most common site of its occurrence. Based on clinical and histological parameters, all the cases were diagnosed as primary malignant melanoma, which were further confirmed by using immunohistochemical markers. PMID:23087742

    Primary malignant tumors of the small bowel are uncommon in the United States. They comprise less than 1% of all gastrointestinal malignancies, with an incidence of 2200 cases per year. The clinical presentation of small bowel tumors is frequently insidious and often overlooked by physicians. The low incidence and lack of pathognomonic symptoms are the reasons that the early diagnosis of malignant small bowel tumor is uncommon. To better understand the clinical presentation, diagnostic evaluation, management, and outcome, a review of Howard University patients with primary malignant small bowel tumors between 1970 and 1990 was conducted. Our experience concurs with the reported literature and supports the conclusion that a high index of suspicion is necessary. The diagnosis of a malignant small bowel tumor should be considered in patients with vague chronic abdominal complaints. Images Figure 1 Figure 2 PMID:7752280

    Double gynecologic cancer (primary cancers in two organs) is relatively rare. However, triple gynecologic cancer (primary cancers in three organs) is extremely rare. We experienced a case of triple cancer, with primary cervical, endometrial and ovarian cancers, each showing different histopathological features. A 50-year-old woman with a preoperative diagnosis of cervical cancer stage Ib1 with a pathological diagnosis of mucinous adenocarcinoma underwent radical hysterectomy. The pathological diagnoses of the extracted masses were endometrioid adenocarcinoma in the uterine corpus and serous adenocarcinoma in the left ovary. Consequently, triple cancer was diagnosed. After the operation, six cycles of a paclitaxel/carboplatin regimen were administered, and no relapse of the cancers has been observed to date. To our knowledge, this is only the second case report in the international literature of concurrent gynecologic triple cancers of epithelial origin; that is, invasive cervical, endometrial and ovarian cancers, each with different histopathological features.

    In order to assess the diagnostic accuracy of diffusion weighted imaging (DWI) in differentiating between benign and malignant ovarian neoplasms, a systemic meta-analysis was conducted. Relevant studies were retrieved from scientific literature databases, including the PubMed, Wiley, EBSCO, Ovid, Web of Science, Wanfang, China National Knowledge Infrastructure and VIP databases. Following a multi-step screening and study selection process, the relevant data was extracted for use in the present study. Statistical analyses were performed using Meta-disc software version 1.4 and STATA statistical software version 12.0. A total of 285 articles were retrieved from the database searches. Following a careful screening process, 10 case-control studies were selected for the present meta-analysis. The 10 studies investigated the efficacy of DWI in diagnosing ovarian neoplasms, and included a combined total of 1,159 subjects, of which 559 patients had malignant lesions and 600 had benign lesions. The results showed that the pooled sensitivity, pooled specificity, pooled positive likelihood ratio, pooled negative likelihood ratio, pooled diagnostic odds ratio (DOR) and area under the curve of the summary receiver operating characteristics curve of DWI for differentiating between benign and malignant ovarian neoplasms were 0.93, 0.89, 7.58, 0.10, 85.33 and 0.95, respectively. A subgroup analysis based on ethnicity revealed no significant difference between Asians and Caucasians. Another subgroup analysis by magnetic resonance imaging (MRI) type showed that the DORs for GE Healthcare Life Sciences and Siemens AG machines were 100.76 [95% confidence interval (CI), 65.28–155.53] and 30.85 (95% CI, 10.40–91.53), respectively; this indicates that the diagnostic efficiency of the GE Healthcare Life Sciences MRI is superior compared with the Siemens AG MRI.

    Background The increased prevalence of unrecognised malignancy in patients with deep vein thrombosis (DVT) has been well established in secondary care settings. However, data from primary care settings, needed to tailor the diagnostic workup, are lacking. Aim To quantify the prevalence of unrecognised malignancy in primary care patients who have been diagnosed with DVT. Design Prospective follow-up study. Setting All primary care physicians affiliated/associated with a non-teaching hospital in a geographically circumscribed region participated in the study. Method A total of 430 consecutive patients without known malignancy, but with proven DVT were included in the study and compared with a control group of 442 primary care patients, matched according to age and sex. Previously unrecognised, occult malignancy was considered present if a new malignancy was diagnosed within 2 years following DVT diagnosis (DVT group) or inclusion in the control group. Patients with DVT were categorised in to those with unprovoked idiopathic DVT and those with risk factors for DVT (that is, secondary DVT). Results During the 2-year follow-up period, a new malignancy was diagnosed 3.6 times more often in patients with idiopathic DVT than in the control group (2-year incidence: 7.4% and 2.0%, respectively). The incidence in patients with secondary DVT was 2.6%; only slightly higher than in control patients. Conclusion Unrecognised malignancies are more common in both primary and secondary care patients with DVT than in the general population. In particular, patients with idiopathic DVT are at risk and they could benefit from individualised case-finding to detect malignancy. PMID:16954002

    Objective To assess the added value of diffusion-weighted magnetic resonance imaging (DWI) with apparent diffusion coefficient (ADC) values compared to MRI, for characterizing the tubo-ovarian abscesses (TOA) mimicking ovarian malignancy. Materials and Methods Patients with TOA (or ovarian abscess alone; n = 34) or ovarian malignancy (n = 35) who underwent DWI and MRI were retrospectively reviewed. The signal intensity of cystic and solid component of TOAs and ovarian malignant tumors on DWI and the corresponding ADC values were evaluated, as well as clinical characteristics, morphological features, MRI findings were comparatively analyzed. Receiver operating characteristic (ROC) curve analysis based on logistic regression was applied to identify different imaging characteristics between the two patient groups and assess the predictive value of combination diagnosis with area under the curve (AUC) analysis. Results The mean ADC value of the cystic component in TOA was significantly lower than in malignant tumors (1.04 ± 0 .41 × 10−3 mm2/s vs. 2.42 ± 0.38 × 10−3 mm2/s; p < 0.001). The mean ADC value of the enhanced solid component in 26 TOAs was 1.43 ± 0.16×10−3mm2/s, and 46.2% (12 TOAs; pseudotumor areas) showed significantly higher signal intensity on DW-MRI than in ovarian malignancy (mean ADC value 1.44 ± 0.20×10−3 mm2/s vs.1.18 ± 0.36 × 10−3 mm2/s; p = 0.043). The combination diagnosis of ADC value and dilated tubal structure achieved the best AUC of 0.996. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MRI vs. DWI with ADC values for predicting TOA were 47.1%, 91.4%, 84.2%, 64%, and 69.6% vs. 100%, 97.1%, 97.1%, 100%, and 98.6%, respectively. Conclusions DW-MRI is superior to MRI in the assessment of TOA mimicking ovarian malignancy, and the ADC values aid in discriminating the pseudotumor area of TOA from the solid portion of ovarian malignancy.

    Introduction: Malignant Mixed Mullerian Tumor (MMMT) is a very rare tumor, accounting for less than 1% of all ovarian cancers. Case Presentation: We present a 64-year-old woman with stage III MMMT of ovary that was treated with platinum-based chemotherapy after optimal cytoreductive surgery. After 25 months of being disease free, she had a pelvic recurrence and a good response to chemoradiotherapy. Conclusions: Optimal cytoreductive surgery and chemotherapy may be the best treatment in MMMT but more discussion and experiences are needed regarding the effectiveness of radiotherapy.

    Girls and young women suffering from a malignant disease that requires treatment with chemo- and/or radiotherapy are at risk of losing fertility. The most significant risk factors are age and type of treatment given. Preserving fertility is of high priority to both the young patient and her parents. This article reviews the effect of chemo- and radiotherapy on gonadal function, and thus fertility, and offers different fertility preserving methods based on the literature. Cryopreservation of ovarian tissue is a possible way of preserving fertility in this group of patients in the future. PMID:19874293

    Primary malignant melanoma of vagina is a rare variant of melanoma and usually associated with a grave prognosis. Radical surgery is the only treatment option with reasonable loco regional control. A case of primary malignant melanoma involving whole of vagina infiltrating urethra and reaching up to vulva was treated by surgery and postoperative radiotherapy. The tumor was infiltrating bladder and rectum reaching the anal sphincter. Total pelvic exenteration was done to achieve tumor-free surgical margins. One year after treatment, patient is disease free. PMID:27186045

    A 66-year-old male with multiple liver tumors was diagnosed as having malignant carcinoid. The case exhibited carcinoid syndrome with wheezing and high urine 5-Hydroxy-Indole Acetic Acid and serum serotonin concentrations. A search for the primary lesion failed to detect tumors except those in the liver, leading to the diagnosis of primary hepatic carcinoid. Repeated transcatheter arterial chemoembolization with degradable starch microspheres decreased the tumors in size and improved the subjective symptoms. Transcatheter arterial chemoembolization with degradable starch microspheres is a useful treatment for unresectable malignant carcinoid of liver origin. PMID:17523279

    Surgical management of ovarian tumours largely depends on their histo-pathological diagnosis. Currently, screening for ovarian malignancy with tumour markers in conjunction with radiological investigations has a low specificity for discriminating benign from malignant tumours. Also, pre-operative biopsy of ovarian masses increases the risk of intra-peritoneal dissemination of malignancy. Intra-operative frozen section, although sufficiently accurate in differentiating tumours according to their histological type, increases operation times. This results in increased surgery-related risks to the patient and additional burden to resource allocation. We set out to determine whether attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy, combined with chemometric analysis can be applied to discriminate between normal, borderline and malignant ovarian tumours and classify ovarian carcinoma subtypes according to the unique spectral signatures of their molecular composition. Formalin-fixed, paraffin-embedded ovarian tissue blocks were de-waxed, mounted on Low-E slides and desiccated before being analysed using ATR-FTIR spectroscopy. Chemometric analysis in the form of principal component analysis (PCA), successive projection algorithm (SPA) and genetic algorithm (GA), followed by linear discriminant analysis (LDA) of the obtained spectra revealed clear segregation between benign versus borderline versus malignant tumours as well as segregation between different histological tumour subtypes, when these approaches are used in combination. ATR-FTIR spectroscopy coupled with chemometric analysis has the potential to provide a novel diagnostic approach in the accurate diagnosis of ovarian tumours assisting surgical decision making to avoid under-treatment or over-treatment, with minimal impact to the patient.

    A 71-year old women presented with fever, a significant loss of body weight and abdominal pain in the upper right quadrant since approximately six months. Abdominal ultrasonography and magnetic resonance imaging (MRI) showed an irregularly shaped, inhomogeneous and hypointense lesion of the right liver lobe (6 x 8 cm in segment 7 and 8) with multiple satellite lesions. Irregular shape, hypovascular presentation during gadolinium enhancement, hypointensity in T 1-weighted images and dilation of peripheral bile ducts were suggestive for cholangiocarcinoma or metastasis. However, histological investigations revealed a rare case of primary actinomycosis of the liver which was successfully treated with antibiotics. PMID:19809957

    Our previous study revealed that two splicing factors, polypyrimidine tract-binding protein (PTB) and SRp20, were upregulated in epithelial ovarian cancer (EOC) and knockdown of PTB expression inhibited ovarian tumor cell growth and transformation properties. In this report, we show that knockdown of SRp20 expression in ovarian cancer cells also causes substantial inhibition of tumor cell growth and colony formation in soft agar and the extent of such inhibition appeared to correlate with the extent of suppression of SRp20. Massive knockdown of SRp20 expression triggered remarkable apoptosis in these cells. These results suggest that overexpression of SRp20 is required for ovarian tumor cell growth and survival. Immunohistochemical staining for PTB and SRp20 of two specialized tissue microarrays, one containing benign ovarian tumors, borderline/low malignant potential (LMP) ovarian tumors as well as invasive EOC and the other containing invasive EOC ranging from stage I to stage IV disease, reveals that PTB and SRp20 are both expressed differentially between benign tumors and invasive EOC, and between borderline/LMP tumors and invasive EOC. There were more all-negative or mixed staining cases (at least two evaluable section cores per case) in benign tumors than in invasive EOC, whereas there were more all-positive staining cases in invasive EOC than in the other two disease classifications. Among invasive EOC, the majority of cases were stained all positive for both PTB and SRp20, and there were no significant differences in average staining or frequency of positive cancer cells between any of the tumor stages. Therefore, the expression of PTB and SRp20 is associated with malignancy of ovarian tumors but not with stage of invasive EOC. PMID:20856201

    FMR1 premutation (PM) alleles have 55-200 CGG·CCG-repeats in their 5' UTR. PM carriers are at risk of fragile X-associated tremor and ataxia syndrome (FXTAS). Females are also at risk for FX primary ovarian insufficiency (FXPOI). PM pathology is generally attributed to deleterious properties of transcripts with long CGG-tracts. For FXPOI, hormone changes suggest a reduced residual follicle pool. Whether this is due to a smaller than normal original follicle pool or an increased rate of follicle depletion is unclear. A FX-PM mouse the authors generated with 130 CGG·CCG-repeats in the endogenous Fmr1 gene recapitulates features of FXTAS. Here the authors demonstrate that the gross development of the ovary and the establishment of the primordial follicle pool is normal in these mice. However, these animals show a faster loss of follicles of all follicle classes, suggesting that the problem is intrinsic to the ovary. In addition, many oocytes show aberrant nuclear accumulation of FMRP and elevated levels of ubiquitination. Furthermore, PM follicles are smaller and have fewer granulosa cells (GCs) than normal. Thus, these animals have ovarian abnormalities involving both the oocytes and GCs that may shed light on the molecular basis of FXPOI in humans. PMID:22470123

    Primary malignant melanoma of the urinary bladder is a rare lesion. We report the case of a 78-year-old male with no previous history of cutaneous melanoma who presented with hematuria. Further investigation with imaging and cystoscopy raised suspicion of a primary bladder and ureteric melanoma, which had subsequently metastasized. This was confirmed with histological assessment and a thorough search for alternative primary lesions. Unfortunately, our patient passed away prior to receiving any oncological treatment for his metastatic melanoma, underscoring both the high mortality of this lesion and the need for a consensus on definitive treatment.

    Primary malignant melanoma of the oesophagus is a rare and aggressive malignancy. This tumour entity accounts for 0.1–0.2% of all oesophageal malignancies and risk factors are yet to be established, although melanosis of the oesophagus may reflect its precursor form. Dysphagia is the commonest symptom. On gastroscopy, it appears as an elevated pigmented mass with satellite lesions in some cases. Unfortunately, most patients present late with metastatic disease. The prognosis is poor with a mean survival time post-operatively of 10–14 months and a 5-year survival rate of 4.5%. Although adjuvant therapy offers some loco-regional control, complete surgical resection offers the best hope for survival. PMID:24876370

    Transarterial therapies in the setting of primary and secondary liver malignancies are becoming an essential part of the oncology landscape. Most patients with hepatic malignancies are not candidates for curative surgical intervention, thereby warranting exploration of alternative means of treatment that preserves quality of life while providing clinical benefit. Herein, the data for intra-arterial chemoinfusion, transarterial chemoembolization, drug-eluting beads, and radioembolization are discussed in the setting of malignancies within the liver; outcome data relating to survival, time-to-progression, time-to-recurrence, and adverse events are presented. Further data regarding different treatment paradigms for hepatocellular carcinoma, metastatic colorectal carcinoma, neuroendocrine tumours, and intrahepatic cholangiocarcinoma are also provided. In light of these and forthcoming data, transarterial therapies seem to offer a viable treatment pathway for select populations of patients. PMID:25985939

    Malignant germ cell tumors of the ovary are very rare and account for about 2-5% of all ovarian tumors of germ origin. Most patients are adolescent and young women, approximately two-thirds of them are under 20 years of age, occasionally in postmenopausal women. But clear cell carcinoma usually occurs in older patients (median age: 57-year old), and closely related with endometriosis. Here we report a case of a 55-year old woman with right ovarian mass that discovered by B ultrasonic. Her serum levels of human chorionic gonadotropin (hCG) and α-fetoprotein (AFP) were elevated. Pathological examination revealed the tumor to be a mixed germ cell tumor (yolk sac tumor, embryonal carcinoma and mature teratoma) with clear cell carcinoma in a background of endometriosis. Immunohistochemical staining showed SALL4 and PLAP were positive in germ cell tumor area, hCG, CD30 and OCT4 were positive in epithelial-like cells and giant synctiotrophoblastic cells, AFP, AAT, CD117 and Glyp3 were positive in yolk sac component, EMA and CK7 were positive in clear cell carcinoma, CD10 was positive in endometrial cells of endometriotic area. She was treated with surgery followed by seven courses of chemotherapy. She is well and serum levels of hCG and AFP have been decreased to normal levels. PMID:25674278

    Photoacoustic spectra of normal, benign, and malignant ovarian tissues are recorded using 325-nm pulsed laser excitation in vitro. A total of 102 (34 normal, 38 benign, and 30 malignant) spectra are obtained from 22 samples belonging to normal, benign, and malignant subjects. Applying multi-algorithm approach, comprised of methods such as, principal component analysis (PCA) based k-nearest neighbor (k-NN) analysis, artificial neural network (ANN) analysis, and support vector machine (SVM) analysis, classification of the data has been carried out. For PCA, first the calibration set is formed by pooling 45 spectra, 15 belonging to each of pathologically certified normal, benign, and malignant samples. PCA is then performed on the data matrix, comprised of the six spectral features extracted from each of 45 calibration samples, and three principal components (PCs) containing maximum diagnostic information are selected. The scores of the selected PCs are used to train the k-NN, ANN, and SVM classifiers. The ANN used is a classical multilayer feed forward network with back propagation algorithm for its training. For k-NN, the Euclidean distance based algorithm is used and for SVM, one-versus-rest multiclass kernel-radial basis function is used. The performance evaluation of the classification results are obtained by calculating statistical parameters like specificity and sensitivity. ANN and k-NN techniques showed identical performance with specificity and sensitivity values of 100 and 86.76%, whereas SVM had these values at 100 and 80.18%, respectively. In order to determine the relative diagnostic performance of the techniques, receiver operating characteristics analysis is also performed.

    Objective To describe the safety and efficacy of radiofrequency ablation (RFA) to treat unresectable malignant hepatic tumors in 123 patients. Background The majority of patients with primary or metastatic malignancies confined to the liver are not candidates for resection because of tumor size, location, or multifocality or inadequate functional hepatic reserve. Local application of heat is tumoricidal; therefore, the authors investigated a novel RFA system to treat patients with unresectable hepatic cancer. Patients and Methods Patients with hepatic malignancies were entered into a prospective, nonrandomized trial. The liver tumors were treated percutaneously or during surgery under ultrasound guidance using a novel LeVeen monopolar array needle electrode and an RF 2000 generator. All patients were followed to assess complications, treatment response, and recurrence of malignant disease. Results RFA was used to treat 169 tumors (median diameter 3.4 cm, range 0.5 to 12 cm) in 123 patients. Primary liver cancer was treated in 48 patients (39.1%), and metastatic liver tumors were treated in 75 patients (60.9%). Percutaneous and intraoperative RFA was performed in 31 patients (35.2%) and 92 patients (74.8%), respectively. There were no treatment-related deaths, and the complication rate after RFA was 2.4%. All treated tumors were completely necrotic on imaging studies after completion of RFA treatments. With a median follow-up of 15 months, tumor has recurred in 3 of 169 treated lesions (1.8%), but metastatic disease has developed at other sites in 34 patients (27.6%). Conclusions RFA is a safe, well-tolerated, and effective treatment to achieve tumor destruction in patients with unresectable hepatic malignancies. Because patients are at risk for the development of new metastatic disease after RFA, multimodality treatment approaches that include RFA should be investigated. PMID:10400029

    The peak incidence of malignant ovarian germ cell tumours occurs soon after puberty. Thus, gonadal steroids may play a role in their development. Oestrogen receptors (ERalpha and ERbeta) and their co-regulators, including small nuclear ring finger protein 4 (SNURF/RNF4) mediate oestrogen actions. While ERbeta and SNURF are down-regulated in testicular germ cell tumours, their role in the ovarian germ cell tumours remains unknown. We herein studied the different subtypes of malignant ovarian germ cell tumours, and found that they all express ERalpha, ERbeta, and SNURF. Stimulation with oestradiol (E2), ERalpha, ERbeta and SNURF significantly up-regulated mRNA expression in the human germinoma derived NCC-IT cells. Further, the effects of E2 were counteracted by an anti-oestrogen (ICI 182,780). Neither E2 nor ICI 182,780 had an effect on the proliferation of NCC-IT cells as assessed by flow cytometric analysis. Our results suggest that oestrogen signalling has a role in malignant ovarian germ cell tumours. PMID:19524139

    In the management of patients with prostate cancer, the development of new radiographic findings can mimic progression of the disease, thereby triggering changes in treatment. Typically, clinicians evaluate additional parameters, such as symptoms and prostate specific antigen (PSA) levels, for further evidence of disease progression. In the absence of additional findings, for example, elevated PSA, the possibility of an additional malignancy should be considered and evaluated. We present three cases of patients undergoing treatment for prostate adenocarcinoma and discovered on imaging to have findings suggestive of disease progression, but ultimately found to be a new primary malignancy. Our cases suggest that, in patients with prostate cancer, the appearance of new lymphadenopathy or bone lesions cannot be assumed to solely represent progression of the prostate cancer and warrant further investigation, especially in the presence of stable PSA levels.

    Objectives To evaluate the validity and compare the performance of cancer antigen-125 (CA-125), human epididymis protein 4 (HE4), the risk of malignancy index (RMI), and the risk of ovarian malignancy algorithm (ROMA) in the diagnosis of ovarian cancer in patients with ovarian lesions discovered during their preoperative work-up investigations. Methods This prospective, cross-sectional study looked at patients who attended the gynecology department at the Royal Hospital, Muscat, from 1 March 2014 to 30 April 2015, for the evaluation of an ovarian lesion. The inclusion criteria included women who underwent surgical intervention and who had a preoperative pelvic ultrasound with laboratory investigation for CA-125 and HE4. The study validated the diagnostic performance of CA-125, RMI, HE4, and ROMA using histopathological diagnosis as the gold standard. Results The study population had a total of 213 cases of various types of benign (77%) and malignant (23%) ovarian tumors. CA-125 showed the highest sensitivity (79%) when looking at the total patient population. When divided by age, the sensitivity was 67% in premenopausal women. In postmenopausal women, CA-125 had lower sensitivity (89%) compared to RMI, HE4, and ROMA (93% each). A high specificity of 90% was found for HE4 in the total patient population, 93% in premenopausal women and 75% in postmenopausal women. CA-125 had the highest specificity (79%) in postmenopausal women. Both CA-125 and RMI were frequently elevated in benign gynecological conditions particularly in endometriosis when compared to HE4 and ROMA. We also studied modifications of the optimal cut-offs for the four parameters. Both CA-125 and RMI showed a significant increase in their specificity if the cut-off was increased to ≥ 60 U/mL for CA-125 and to ≥ 250 for RMI. For HE4, we noted an improvement in its specificity in postmenopausal women when its cut-off was increased to140 pmol/L. Conclusions HE4 and ROMA showed a very high specificity

    Ovarian cancer remains the disease with the highest associated mortality rate of gynecologic malignancy due to cancer metastasis. Rearrangement of actin cytoskeleton by cytoskeleton protein plays a critical role in tumor cell metastasis. MICAL-L2, a member of MICAL family, can interact with actin-binding proteins, regulate actin cross-linking and coordinate the assembly of adherens junctions and tight junctions. However, the roles of MICAL-L2 in tumors and diseases have not been explored. In this study, we found that MICAL-L2 protein is significantly up-regulated in ovarian cancer tissues along with FIGO stage and associated with histologic subgroups of ovarian cancer. Silencing of MICAL-L2 suppressed ovarian cancer cell proliferation, migration and invasion ability. Moreover, silencing of MICAL-L2 prevented nuclear translocation of β-catenin, inhibited canonical wnt/β-catenin signaling and induced the mesenchymal-epithelial transition (MET). Taken together, our data indicated that MICAL-L2 may be an important regulator of epithelial-mesenchymal transition (EMT) in ovarian cancer cells and a new therapeutic target for interventions against ovarian cancer invasion and metastasis.

    The paper discusses the capability for active movement in an extracellular matrix, wherein remodeling of the cytoskeleton by actin binding proteins plays a significant role in metastases formation. We studied the expression of actin binding proteins and β-catenin in tissues of primary tumors and metastases of ovarian and breast cancer. Contents of p45 Ser β-catenin and the actin severing protein gelsolin were decreased in metastases of ovarian cancer relative to primary tumors. The level of the cofilin, functionally similar to gelsolin, was significantly higher in metastases compared to primary ovarian and breast tumor tissue. In breast cancer, significant increase in the number of an actin monomer binder protein thymosin-β4 was observed in metastases as compared to primary tumors. The data obtained suggest the involvement of locomotor proteins in metastases formation in ovarian and breast cancer.

    The authors present the clinical case of an 87-year-old Caucasian male admitted to the emergency room with hematemesis. He had a history of intermittent dysphagia during the previous month. Endoscopic evaluation revealed an eccentric, soft esophageal lesion located 25-35 cm from the incisors, which appeared as a protrusion of the esophagus wall, with active bleeding. Biopsies were acquired. Tissue evaluation was compatible with a melanoma. After excluding other sites of primary neoplasm, the definitive diagnosis of Primary Malignant Melanoma of the Esophagus (PMME) was made. The patient developed a hospital-acquired respiratory infection and died before tumor-directed treatment could begin. Primary malignant melanoma represents only 0.1% to 0.2% of all esophageal malignant tumors. Risk factors for PMME are not defined. A higher incidence of PMME has been described in Japan. Dysphagia, predominantly for solids, is the most frequent symptom at presentation. Retrosternal or epigastric discomfort or pain, melena or hematemesis have also been described. The characteristic endoscopic finding of PMME is as a polypoid lesion, with variable size, usually pigmented. The neoplasm occurs in the lower two-thirds of the esophagus in 86% of cases. PMME metastasizes via hematogenic and lymphatic pathways. At diagnosis, 50% of the patients present with distant metastases to the liver, the mediastinum, the lungs and the brain. When possible, surgery (curative or palliative), is the preferential method of treatment. There are some reports in the literature where chemotherapy, chemohormonotherapy, radiotherapy and immunotherapy, with or without surgery, were used with variable efficacy. The prognosis is poor; the mean survival after surgery is less than 15 mo. PMID:22180718

    A 60-year-old Caucasian male, with a previous history of a 10-year occupational exposure to ionizing radiation, chemical carcinogens, and a long history of tobacco and alcohol abuse, developed synchronous squamous cell carcinoma of the floor of the mouth and adenocarcinoma of the lung. Four years later, squamous cell carcinoma of the larynx followed by squamous cell carcinoma of the tongue were diagnosed. In this case report, we suggest that increased exposure to multiple carcinogenic factors may result in an increased incidence of both synchronous and metachronous primary malignant neoplasms.

    Synchronous primary endometrial and ovarian cancers are uncommon. The purpose of this study was to evaluate the clinicopathological characteristics, treatment and prognosis of synchronous primary endometrial and ovarian cancers. The clinicopathological characteristics of 43 patients with synchronous primary endometrial and ovarian cancers in the Obstetrics and Gynecology Hospital of Fudan University between 1999 and 2009 were retrospectively reviewed. Our results revealed that the median age at the time of diagnosis was 51 years (range, 29–71). The common presenting symptoms were abnormal uterine bleeding (AUB, 65.12%), abdominal mass (25.58%), abdominal pain and abdominal fullness (39.53%). An elevated CA125 level was observed in the majority of patients (n=20, 76.9%). Endometrioid type accounted for 60.47% of uterine carcinomas and different pathological types, including serous adenocarcinoma, clear cell carcinoma, adenosquamous and acanthoadenocarcinoma, were also identified in synchronous primary endometrial and ovarian cancers. All patients underwent surgical intervention (hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy or debulking surgery). The 5-year survival rate was 86.05% and nine patients had recurrence (20.93%). The early stage group (FIGO stages I and II) had more favorable prognosis than the advanced stage group (FIGO stages III and IV; P<0.05). In conclusion, synchronous primary endometrial and ovarian cancers are different from either primary endometrial carcinoma or ovarian cancer and are usually identified at early stages with a good prognosis.

    Borderline ovarian tumors show heterogeneity in clinical behavior. Most have excellent prognosis, although a small percentage show recurrence or progressive disease, usually to low-grade serous carcinoma. The aim of this study was to understand the molecular relationship between these entities and identify potential markers of tumor progression and therapeutic targets. We studied gene expression using Affymetrix HGU133plus2 GeneChip microarrays in 3 low-grade serous carcinomas, 13 serous borderline tumors and 8 serous cystadenomas. An independent data set of 18 serous borderline tumors and 3 low-grade serous carcinomas was used for validation. Unsupervised clustering revealed clear separation of benign and malignant tumors, whereas borderline tumors showed two distinct groups, one clustering with benign and the other with malignant tumors. The segregation into benign- and malignant-like borderline molecular subtypes was reproducible on applying the same analysis to an independent publicly available data set. We identified 50 genes that separate borderline tumors into their subgroups. Functional enrichment analysis of genes that separate borderline tumors to the two subgroups highlights a cell adhesion signature for the malignant-like subset, with Claudins particularly prominent. This is the first report of molecular subtypes of borderline tumors based on gene expression profiling. Our results provide the basis for identification of biomarkers for the malignant potential of borderline ovarian tumor and potential therapeutic targets for low-grade serous carcinoma. PMID:23948749

  8. Metastatic ovarian papillary cystadenocarcinoma to the small intestine serous surface: report of a case of high-grade histopathologic malignancy

    PubMed Central

    2014-01-01

    Ovarian cystadenocarcinoma is characterized by marked heterogeneity and may be composed of an admixture of histologic growth patterns, including acinar, papillary and solid. In the present study, a case of isolated small intestine metastasis of ovarian papillary cystadenocarcinoma was reported. A 7-year-old female mixed-breed dog presented with a mass in the left upper quadrant with progressive enlargement of the abdomen, periodic bloody discharge from the vulva and incontinence. The tumor was histologically characterized by the presence of cysts and proliferation of papillae, both lined by single- or multi-layered pleomorphic epithelial cells. Furthermore, the mass was composed by intense cellular and nuclear pleomorphism and numerous mitotic figures. These findings indicate a tumor of high-grade malignancy with infiterative tumor cells resembling the papillary ovarian tumor in the serosal surface of the small intestine along with an intact serosa. Immunohistochemically, tumor was positive for CK7 and negative immunoreactivity for CK20. The histopathologic features coupled with the CK7 immunoreactivity led to a diagnosis of high grade ovarian papillary cystadenocarcinoma. To the best of our knowledge, this is the first case of small intestine serousal surface metastasis from ovarian papillary cystadenocarcinoma. PMID:24636424

    In this study, we compared the immunoreactivities of Bcl-2, Bax and p53 proteins in ovarian tumors and related the immunohistochemical findings to the histological type of the tumors. Formalin-fixed, paraffin wax-embedded tissue sections from 40 patients who had serous-mucinous borderline tumors and serous-mucinous adenocarcinoma of the ovary (n=10 each) were stained with hematoxylin-eosin (H&E). After histopathological examination, serial sections were stained immunohistochemically with primary antibodies to Bcl-2, Bax and p53 using an avidin-biotin-peroxidase method. A semi-quantitative grading system was used to compare the immunohistochemical staining intensities. The nuclear DNA fragmentation of apoptosis was determined using TUNEL method. As a result of immunohistochemical staining, increased immunoreactivity of Bcl-2 was observed in adenocarcinomas when compared to borderline tumors (P<0.001). Strong immunoreactivity of Bcl-2 and mild immunoreactivities of Bax and p53 were detected in ovarian adenocarcinomas. There were no significant statistical differences in the immunoreactivity of Bax among the histological type of ovarian tumors. Whereas a balance was observed between the immunoreactivities of Bcl-2 and Bax in the borderline cases, and this balance was strongly changed toward the anti-apoptotic Bcl-2 protein in patients with adenocarcinoma. TUNEL staining of sections indicated apoptotic cells in the serous borderline tumors were about 8-fold higher than in the serous adenocarcinoma. The results of this study on apoptosis-related factors might help to develop novel protective and therapeutic approaches, such as isoflavonoids and isothiocyanates, which were associated with decreased Bcl-2/Bax ratio, against the malignant epithelial ovarian tumors.

    The malignant behavior of an ovarian teratoma is related to immaturity, or rarely to the malignant transformation of a somatic component in a mature teratoma (MT). The aim of this work was to review 189 consecutive ovarian teratomas diagnosed between 2006 and 2010 at a public referral center for cancer in Brazil, focusing on cases of MT with malignant transformation. MTs with transformation to squamous cell carcinoma (SCC) were further analyzed by immunohistochemistry for p16 staining. The median age of all patients was 36 yr (mean age, 39.6 yr; SD±4.9). Mature and immature teratomas represented 95.7% (181/189) and 4.2% of the cohort, respectively. Immature teratoma occurred mainly in adolescents under 18 yr. Malignant transformation of the somatic component in MT was observed in 10 of 181 patients (5.5%). SCC was the most common subtype (4/10), followed by differentiated thyroid carcinoma in struma ovarii(3/10), adenosquamous carcinoma (1/10), mucinous intestinal-type adenocarcinoma (1/10), and a well-differentiated neuroendocrine tumor/carcinoid (1/10). Two of 4 SCC cases were strong and diffusely positive for p16, and 2 were negative. In 5 further patients, MT was synchronously observed with other benign and malignant ovarian neoplasms in the ipsilateral ovary (3 mucinous cystadenomas and 1 Brenner tumor) and 1 cystadenocarcinoma in the contralateral ovary. MTs with malignant transformation were larger than those without transformation (P<0.001), but did not demonstrate any association with age. Indeed, our patients with SCC in MT were much younger [median and mean age, 37 and 38 yr (SD±4.9), respectively] than those described previously. As p16 is considered a surrogate marker for HPV infection, the malignant transformation of MT into SSC in young patients raises the possibility of HPV infection as a risk factor in some of these cases. However, molecular studies are needed to clarify the possible role of HPV in the malignant transformation of MT to SCC. PMID

    Abstract Primary malignant melanoma of the esophagus (PMME) is a rare disease with an extremely poor prognosis. We experienced a 79-year-old man with PMME who had unusual endoscopic findings. On endoscopy, an elongated lump was detected on 1 side of the vertical axis of the esophagus. The mass extended progressively for 15 cm along the esophageal longitudinal axis and invaded half of the esophageal circumference. These endoscopic findings were not characteristic of PMME, and the condition was confirmed with biopsy and immunohistochemical staining. Here, we present this rare case and review the recent relevant literature regarding PMME. Doctors should be aware that PMME might present with unusual endoscopic findings. PMID:27124046

    Background Primary chest wall tumors originate from different constructions of thoracic wall. We report our multidisciplinary experience on primary thoracic tumor resection and thoracic reconstruction, the need to additional therapy and evaluating prognostic factors affecting survival. Methods We performed a retrospective review of our prospectively maintained database of 40 patients treated for malignant primary chest wall tumor from 1989 to 2009. Patients were evaluated in terms of age, sex, clinical presentation, type of imaging, tissue diagnosis methods, pathology, surgical technique, early complications, hospital mortality, prevalence of recurrence and distant metastases, additional treatment, 3 years survival and factors affecting survival. Results Male/Female (F/M) = 1, with median age of 43.72 years. Mass was the most common symptoms and the soft tissue sarcoma was the most common pathology. Resection without reconstruction was performed in 5 patients and Thirty-five patients (87.5%) had extensive resection and reconstruction with rotatory muscular flap, prosthetic mesh and/or cement. Overall, 12.5% (5/40) of patients received neoadjuvant therapy and 75% (30/40) of patients were treated with adjuvant therapy. The 3-year survival rate was 65%. Recurrences occurred in 24 patients (60%), 14 developed local recurrences, and 10 developed distant metastases. The primary treatment modality for both local and distant recurrences was surgical resection; among them, 10 underwent repeated resection, 9 adjuvant therapy and 5 were treated with lung metastasectomy. The most common site of distant metastasis was lung (n = 7). Factors that affected survival were type of pathology and evidence of distant metastasis. Conclusion Surgery with wide margin is the safe and good technique for treatment of primary chest wall tumors with acceptable morbidity and mortality. PMID:24947314

    Ovarian cancer is the most lethal gynaecologic malignancy. It usually spreads out of the abdomen involving thoraco-abdominal organs and serosal surface. This disease is poorly curable and surgery, at early stage, is supposed to achieve the best survival outcome. In systemic dissemination, chemotherapy is indicated, sometimes with neoadjuvant aim. The most common clinical expressions of advanced ovarian carcinoma are multiple adenopathy, neoplastic pleuritis, peritoneal seeding and distant metastasis, mainly hepatic and pulmonary. Isolated adenopathy of the mediastinum is rare and isolated bilateral have never been described before. We report two cases of isolated bilateral cardiophrenic angle lymph node metastasis from ovarian carcinoma, without peritoneal and pleural involvement. Both patients were successfully resected through minimally invasive thoracic surgery. About the role of surgery, few data are available but survival seems to be longer after resection thus, more investigation is required to make the indication to surgery more appropriate in advanced cases.

    Abstract Multiple primary malignancies (MPMs) are defined as 2 or more malignancies without subordinate relationship detected in different organs of an individual patient. Reports addressing MPM patients with hepatocellular carcinoma (HCC) are rare. We perform a 26-year follow-up study to investigate characteristics and prognosis of MPM patients associated with HCC due to the scarcity of relative researches. We retrospectively analyzed records of 40 patients who were diagnosed with MPM including HCC at the Departments of Surgery at Peking Union Medical College Hospital during 1989 to 2010. Their clinical characteristics and postoperative survival were compared with those of 448 patients who had HCC only during the study period. Among the 40 MPM patients, 11 were diagnosed synchronously and 29 metachronously. The most common extra-hepatic malignancies were lung cancer (15%), colorectal (12.5%), and thyroid carcinoma (12.5%). MPM patients had a negative hepatitis B virus infection rate (P = 0.013) and lower median alfa-fetoprotein (AFP) level (P = 0.001). Post-operative 1-, 3-, and 5-year overall survival (OS) rates for MPM patients were 82.5%, 64.5%, and 38.6% respectively, and showed no significant difference with those of HCC-only patients (84.7%, 54.2%, and 38.3% P = 0.726). During follow-up, 24 MPM patients died, including 17 (70.8%) who died of HCC-related causes. In univariate analysis, synchronous diagnosis, higher gamma glutamyltransferase (GGT) and/or AFP levels, tumor >5 cm and vascular invasion were significantly associated with shorter OS, but only tumor size was an independent OS factor in Cox modeling analysis. HCC should be considered as a potential second primary for all cancer survivors. Most MPM patients died of HCC-related causes and showed no significant difference in OS compared with HCC-only patients. Tumor size of HCC, rather than MPMs itself, was the only independent OS predictor for the MPM patients. PMID:27124050

    A recent exome-sequencing study revealed prevalent mitogen-activated protein kinase 1 (MAPK1) p.E322K mutation in cervical carcinoma. It remains largely unknown whether ovarian carcinomas also harbor MAPK1 mutations. As paralogous gene mutations co‑occur frequently in human malignancies, we analyzed here a total of 263 ovarian carcinomas for the presence of MAPK1 and paralogous MAPK3 mutations by DNA sequencing. A previously unreported MAPK1 p.D321N somatic mutation was identified in 2 out of 18 (11.1%) ovarian mixed germ cell tumors, while no other MAPK1 or MAPK3 mutation was detected in our samples. Of note, OCC‑115, the MAPK1‑mutated sample with bilateral cancerous ovaries affected, harbored MAPK1 mutation in the right ovary while retained the left ovary intact, implicating that the genetic alterations underlying ovarian mixed germ cell tumor may be different, even in patients with similar genetic backgrounds and tumor microenvironments. The results of evolutionary conservation and protein structure modeling analysis implicated that MAPK1 p.D321N mutation may be pathogenic. Additionally, mutations in protein phosphatase 2 regulatory subunit α (PPP2R1A), ring finger protein 43 (RNF43), DNA directed polymerase ε (POLE1), ribonuclease type III (DICER1), CCCTC‑binding factor (CTCF), ribosomal protein L22 (RPL22), DNA methyltransferase 3α (DNMT3A), transformation/transcription domain‑associated protein (TRRAP), isocitrate dehydrogenase (IDH)1 and IDH2 were not detected in ovarian mixed germ cell tumors, implicating these genetic alterations may be not associated with MAPK1 mutation in the development of this malignancy. The present study identified a previously unreported MAPK1 mutation in ovarian mixed germ cell tumors for the first time, and this mutation may be actively involved in the tumorigenesis of this disease.

    This review focuses on the molecular characteristics and development of rare malignant ovarian germ cell tumors (mOGCTs). We provide an overview of the genomic aberrations assessed by ploidy, cytogenetic banding, and comparative genomic hybridization. We summarize and discuss the transcriptome profiles of mRNA and microRNA (miRNA), and biomarkers (DNA methylation, gene mutation, individual protein expression) for each mOGCT histological subtype. Parallels between the origin of mOGCT and their male counterpart testicular GCT (TGCT) are discussed from the perspective of germ cell development, endocrinological influences, and pathogenesis, as is the GCT origin in patients with disorders of sex development. Integrated molecular profiles of the 3 main histological subtypes, dysgerminoma (DG), yolk sac tumor (YST), and immature teratoma (IT), are presented. DGs show genomic aberrations comparable to TGCT. In contrast, the genome profiles of YST and IT are different both from each other and from DG/TGCT. Differences between DG and YST are underlined by their miRNA/mRNA expression patterns, suggesting preferential involvement of the WNT/β-catenin and TGF-β/bone morphogenetic protein signaling pathways among YSTs. Characteristic protein expression patterns are observed in DG, YST and IT. We propose that mOGCT develop through different developmental pathways, including one that is likely shared with TGCT and involves insufficient sexual differentiation of the germ cell niche. The molecular features of the mOGCTs underline their similarity to pluripotent precursor cells (primordial germ cells, PGCs) and other stem cells. This similarity combined with the process of ovary development, explain why mOGCTs present so early in life, and with greater histological complexity, than most somatic solid tumors. PMID:23575763

This similarity combined with the process of ovary development, explain why mOGCTs present so early in life, and with greater histological complexity, than most somatic solid tumors. PMID:23575763

    In most cases of primary ovarian insufficiency (POI), the cause of the depletion of ovarian follicles is unknown. Fanconi anemia (FA) proteins are known to play important roles in follicular development. Using random insertional mutagenesis with a lentiviral transgene, we identified a family with reduced fertility in the homozygous transgenic mice. We identified the integration site and found that the lentivirus had integrated into intron 8 of the Fanconi E gene (Fance). By RT-PCR and in situ hybridization, we found that Fance transcript levels were significantly reduced. The Fance homozygous mutant mice were assayed for changes in ovarian development, follicle numbers and estrous cycle. Ovarian dysplasias and a severe lack of follicles were seen in the mutant mice. In addition, the estrous cycle was disrupted in adult females. Our results suggest that POI has been induced by the Fance mutation in this new mouse model. PMID:26939056

  1. Ovarian metastases resection from extragenital primary sites: outcome and prognostic factor analysis of 147 patients

    PubMed Central

    2012-01-01

    Background To explore the outcomes and prognostic factors of ovarian metastasectomy intervention on overall survival from extragenital primary cancer. Methods Patients with ovarian metastases from extragenital primary cancer confirmed by laparotomy surgery and ovarian metastases resection were retrospectively collected in a single institution during an 8-year period. A total of 147 cases were identified and primary tumor sites were colorectal region (49.0%), gastric (40.8%), breast (8.2%), biliary duct (1.4%) and liver (0.7%). The pathological and clinical features were evaluated. Patients’ outcome with different primary tumor sites and predictive factors for overall survival were also investigated by univariate and multivariate analysis. Results Metachronous ovarian metastasis occurred in 92 (62.6%) and synchronous in 55 (37.4%) patients. Combined metastases occurred in 40 (27.2%). Bilateral metastasis was found in 97 (66%) patients. The median ovarian metastasis tumor size was 9 cm. There were 39 (26.5%) patients with massive ascites ≥ 1000 mL on intraoperative evaluation. With a median follow-up of 48 months, the median OS after ovarian metastasectomy for all patients was 8.2 months (95% CI 7.2-9.3 months). In univariate analyses, there is significant (8.0 months vs. 41.0 months, P = 0.000) difference in OS between patients with gastrointestinal cancer origin from breast origin, and between patients with gastric origin from colorectal origin (7.4 months vs. 8.8 months, P = 0.036). In univariate analyses, synchronous metastases, locally invasion, massive intraoperative ascites (≥ 1000 mL), and combined metastasis, were identified as significant poor prognostic factors. In multivariate analyses combined metastasis (RR, 1.72; 95% CI, 1.09-2.69, P = 0.018), locally invasion (RR, 1.62; 95% CI, 1.03-2.54, P = 0.038) and massive intraoperative ascites (RR, 1.58; 95% CI, 1.02-2.49, P = 0.04) were independent factors for predicting unfavorable

    The combination of Müllerian agenesis with inguinal ovaries accompanied by primary ovarian insufficiency is extremely rare. A 21-year-old Korean woman was referred to our center with primary amenorrhea. The patient was diagnosed with Müllerian agenesis with inguinal ovaries. Her hormonal profile showed hypergonadotrophic hypogonadism suggesting primary ovarian insufficiency. We performed laparoscopic neovaginoplasty using modified Davydov's procedure and reposition inguinal ovaries in the pelvic cavity. Oral estrogen replacement was applied for the treatment of primary ovarian insufficiency. This is a rare case report on Mayer-Rokitansky-Kuster-Hauser syndrome accompanied not only by inguinal ovaries but also with primary ovarian insufficiency. We present our first experience on the laparoscopic neovaginoplasty performed on the patient with müllerian agenesis accompanied by inguinal ovaries and primary ovarian insufficiency. PMID:27462606

    Primary peritoneal serous carcinoma (PPSC) is an extremely rare malignancy that was first described in 1959. This type of cancer arises from the peritoneal epithelium and is similar to serous ovarian carcinoma. A diagnosis of PPSC is typically made based on the Gynecology Oncology Group criteria; however, a correct differential diagnosis of PPSC is difficult preoperatively. The current study describes the case of a 66 year-old female patient presenting with abdomen distension. A computed tomography (CT) scan revealed abundant ascites in the abdominal cavity and omental infiltration. The results of positron emission tomography/CT showed hot uptake in the greater omentum. Furthermore, preoperative serum cancer antigen-125 levels were 1,032 U/ml. Upon surgical exploration, a whitish mass and nodule were found in the greater omentum. Therefore, omentectomy was performed. Pathological examination of the resected specimen revealed a diagnosis of PPSC. PPSC is extremely rare with few cases cited in the current literature. The present study describes a rare case of PPSC with a review of the literature. PMID:27313741

    We describe the clinicopathologic and immunohistochemical features of the first reported case of an ovarian low-grade serous carcinoma metastatic to the cervix mimicking a cervical primary. The patient, a 55-year-old woman, was found to have an abnormal cervix and an abnormal Pap smear during a preoperative workup for a rectocele repair. A subsequent cervical biopsy contained moderately differentiated adenocarcinoma and the patient underwent a cold knife conization. An infiltrating adenocarcinoma was found in the anterior cervical lip, the neoplasm reached the surface of the endocervical canal and was composed of mildly to moderately atypical, eosinophilic or amphophilic columnar cells arranged in glands and papillae. Mitotic figures were rare and no apoptotic bodies were seen. Psammoma bodies and intraglandular mucinous material were also noted. There was extensive vascular/lymphatic invasion. The tumor extended to all margins and was interpreted as a moderately differentiated (grade 2) adenocarcinoma of the uterine cervix with a linear spread of at least 1.4 cm and a depth of at least 0.6 cm (FIGO stage 1B1). The patient was treated with radiotherapy and cisplatin. Six months later, surveillance imaging studies showed that the patient's ovaries seemed to be enlarging. The patient underwent exploratory laparotomy, bilateral salpingo-oophorectomy, right pelvic lymph node sampling, omentectomy, peritoneal biopsies, and pelvic washings. The ovaries contained bilateral cystic tumors. There was gross tumor involving multiple peritoneal sites. Microscopic examination of the ovaries showed the typical features of low-grade serous carcinoma associated with a serous neoplasm of low malignant potential with a cribriform pattern. Metastatic low-grade serous carcinoma was detected in multiple peritoneal sites and in the pelvic washings. A consultation was obtained, with the consultant concurring that the tumors represented independent primaries. The patient received

    Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses. Features of a mature cystic teratoma were seen very focally. Immunohistochemistry revealed strong, diffuse positivity for CD56 and synaptophysin. Chromogranin immunonegativity was noted and there was an absence of nuclear β-catenin accumulation. Ki-67 index was 10-12%. Although there is no established diagnostic framework for primary ovarian carcinoid tumors, this case was diagnosed as a well-differentiated neuroendocrine tumor, Grade 2 (intermediate grade), arising in association with a mature cystic teratoma/dermoid cyst. This case highlights the need to develop ovarian diagnostic criteria in this area. PMID:27508272

    BACKGROUND Primary ovarian insufficiency (POI) is characterized by marked heterogeneity, but with a significant genetic contribution. Identifying exact causative genes has been challenging, with many discoveries not replicated. It is timely to take stock of the field, outlining the progress made, framing the controversies and anticipating future directions in elucidating the genetics of POI. METHODS A search for original articles published up to May 2015 was performed using PubMed and Google Scholar, identifying studies on the genetic etiology of POI. Studies were included if chromosomal analysis, candidate gene screening and a genome-wide study were conducted. Articles identified were restricted to English language full-text papers. RESULTS Chromosomal abnormalities have long been recognized as a frequent cause of POI, with a currently estimated prevalence of 10–13%. Using the traditional karyotype methodology, monosomy X, mosaicism, X chromosome deletions and rearrangements, X-autosome translocations, and isochromosomes have been detected. Based on candidate gene studies, single gene perturbations unequivocally having a deleterious effect in at least one population include Bone morphogenetic protein 15 (BMP15), Progesterone receptor membrane component 1 (PGRMC1), and Fragile X mental retardation 1 (FMR1) premutation on the X chromosome; Growth differentiation factor 9 (GDF9), Folliculogenesis specific bHLH transcription factor (FIGLA), Newborn ovary homeobox gene (NOBOX), Nuclear receptor subfamily 5, group A, member 1 (NR5A1) and Nanos homolog 3 (NANOS3) seem likely as well, but mostly being found in no more than 1–2% of a single population studied. Whole genome approaches have utilized genome-wide association studies (GWAS) to reveal loci not predicted on the basis of a candidate gene, but it remains difficult to locate causative genes and susceptible loci were not always replicated. Cytogenomic methods (array CGH) have identified other regions of interest

    Objective To evaluate the use of as an aid in the identification of women who can safely undergo conservative, non-surgical management. Methods All patients referred to the Program in Women’s Oncology for surgery with a pelvic mass are evaluated at a prospective multidisciplinary tumor board (TB) where ROMA and imaging are used for management recommendations. This study evaluated women presented to TB with a pelvic mass between 2009 and 2013 who had either surgical or conservative management. Results Of the 498 patients assessed, 392 (79%) had benign disease, 22 (4%) had LMP tumors, 28 (6%) had stage I-II epithelial ovarian cancer (EOC), 36 (7%) had stage III-IV EOC and 20 (4%) had non-EOC. Using clinical assessment in conjunction with ROMA, the TB recommended observation in 188 (37.8%) women. All patients diagnosed with an invasive malignancy were recommended for surgery by the TB. In the 315 patients managed surgically, 212 were found to have benign disease and 84 women were diagnosed with an invasive malignancy. The sensitivity for the initial TB recommendations using ROMA in conjunction with clinical judgment for detecting malignancy was 100% with a specificity of 47.7% and a NPV of 100%. When including low malignant potential tumors the sensitivity was 99.1%. For stage I-IV EOC ROMA alone had a sensitivity of 95.3%. Conclusions ROMA in conjunction with clinical assessment can safely identify women for conservative management. PMID:26364809

    Peutz-Jeghers syndrome is characterized by multiple polyps throughout the gastrointestinal tract in association with mucocutaneous pigmentation. Although Peutz-Jeghers syndrome polyps are hamartomas, frequent association of this syndrome with both gastrointestinal and non-gastrointestinal tumours had led to reassessment of the cancer risk in this hereditary disorder. The most common gynaecological tumors in this syndrome are adenoma malignum of the uterine cervix and ovarian sex cord tumor, particularly sex cord tumor with annular tubules. The question of malignant change in a polyp or of the association of gastro intestinal carcinomas still discuss. The authors report a case of Peutz-Jeghers syndrome in a young patient who developed a colonic adenocarcinoma in a hamartomatous polyp together with an incidentally discovered bilateral malignant sex cord tumours. We discuss its association with certain benign and malignant tumors and the risk of rare complications of these hamartomatous polyps. Although malignant tumors are increasingly reported in association with the Peutz-Jeghers syndrome, to our knowledge, there have been no previous reports of such an association in the literature.

    There are few reports of multiple ovarian cysts secondary to hypothyroidism, and multiple ovarian cysts associated with pregnancy most commonly occur in association with assisted reproductive technologies. Herein, we report a case of a naturally conceived pregnancy occurring 2 years after stopping treatment for primary hypothyroidism. The patient developed multiple ovarian cysts in the first trimester, and laboratory studies and ultrasonography were consistent with hypothyroidism. Herein, we present the case and discuss the importance of prenatal screening for hypothyroidism. PMID:22309686

  13. Low or undetectable TPO receptor expression in malignant tissue and cell lines derived from breast, lung, and ovarian tumors

    PubMed Central

    2012-01-01

    Background Numerous efficacious chemotherapy regimens may cause thrombocytopenia. Thrombopoietin receptor (TPO-R) agonists, such as eltrombopag, represent a novel approach for the treatment of chemotherapy-induced thrombocytopenia. The TPO-R MPL is expressed on megakaryocytes and megakaryocyte precursors, although little is known about its expression on other tissues. Methods Breast, lung, and ovarian tumor samples were analyzed for MPL expression by microarray and/or quantitative reverse transcription-polymerase chain reaction (qRT-PCR), and for TPO-R protein expression by immunohistochemistry (IHC). Cell line proliferation assays were used to analyze the in vitro effect of eltrombopag on breast, lung, and ovarian tumor cell proliferation. The lung carcinoma cell lines were also analyzed for TPO-R protein expression by Western blot. Results MPL mRNA was not detectable in 118 breast tumors and was detectable at only very low levels in 48% of 29 lung tumors studied by microarray analysis. By qRT-PCR, low but detectable levels of MPL mRNA were detectable in some normal (14-43%) and malignant (3-17%) breast, lung, and ovarian tissues. A comparison of MPL to EPOR, ERBB2, and IGF1R mRNA demonstrates that MPL mRNA levels were far lower than those of EPOR and ERBB2 mRNA in the same tissues. IHC analysis showed negligible TPO-R protein expression in tumor tissues, confirming mRNA analysis. Culture of breast, lung, and ovarian carcinoma cell lines showed no increase, and in fact, showed a decrease in proliferation following incubation with eltrombopag. Western blot analyses revealed no detectable TPO-R protein expression in the lung carcinoma cell lines. Conclusions Multiple analyses of breast, lung, and ovarian tumor samples and/or cell lines show no evidence of MPL mRNA or TPO-R protein expression. Eltrombopag does not stimulate growth of breast, lung, or ovarian tumor cell lines at doses likely to exert their actions on megakaryocytes and megakaryocyte precursors. PMID

    2016-01-01

    Primary sclerosing cholangitis (PSC) is a chronic inflammatory liver disease of unknown etiology, primarily targeting cholangiocytes at any portion of the biliary tree. No effective medical treatments are currently available. A unique feature of PSC is its close association (about 80%) with inflammatory bowel disease (IBD), mainly ulcerative colitis (UC). As in many chronic inflammatory conditions, cancer development can complicate PSC, accounting for >40% of deaths. Cholangiocarcinoma (CCA), gallbladder carcinoma (GBC) and colorectal carcinoma (CRC) have been variably associated to PSC, with a prevalence up to 13–14%. The risk of cancer is one of the most challenging issues in the management of PSC; it raises several questions about cancer surveillance, early diagnosis, prevention and treatment. Key Messages Among the different cancers complicating PSC, CCA is the most relevant, because it is more frequent (incidence of 0.5–1.5%) and because the prognosis is poor (5-year survival <10%). Early diagnosis of CCA in PSC can be difficult because lesions may not be evident in radiological studies. Surgical resection provides disappointing results; liver transplantation combined with neoadjuvant chemoradiotherapy is being proposed, but this approach is limited to a highly selected group of patients and is available only in a few specialized centers. Similar to CCA, GBC carries a dismal prognosis. Since it is difficult to discriminate GBC from other gallbladder abnormalities, cholecystectomy has been proposed in all gallbladder lesions detected in PSC, regardless of their size. CRC is a frequent complication of PSC associated to UC; its incidence steadily increases with time of colitis, reaching up to 20–30% of the patients after 20 years. Colonoscopy with extensive histologic sampling at an annual/biannual interval is an effective surveillance strategy. However, when dysplastic lesions are detected, preemptive proctocolectomy should be considered. Conclusions PSC

    Ovarian carcinoids are very rare, and only their insular form is associated with carcinoid syndrome. We herein describe a case report of an elderly woman who presented with typical carcinoid syndrome, which is routinely characterized by right-sided heart failure, diarrhoea, flushes, and other common manifestations. Further examination and biochemical testing of the patient confirmed suspected carcinoid tumor. However, the tumor was surprisingly localized in the left ovary. The presence of the patient’s severe combined tricuspid valve disease would create impossible surgical management conditions, so we decided to first perform cardio-surgery with tricuspid valve replacement. After tumor removal, levels of hydroxyindolacetic acid did not normalize and although the patient was asymptomatic, a small lesion was detected by tectrotyd scan paravertebrally. Treatment with lanreotide led to complete remission with negative biochemical and imaging signs of tumor. Thus, to summarize, carcinoid tumor even in an atypical localization (ovary) should be considered in elderly female patients with severe combined tricuspid valve disease due to carcinoid syndrome.

    Aggressive surgery may improve the outcome of patients with ovarian cancer. To assess the risk of operative complications, we analyzed 472 primary and 299 repeat operations for ovarian cancer in 536 women between 14-91 years of age. Intraoperative bleeding estimated to be over 1000 mL (N = 107) was more common after primary (21%) than repeat surgery (3%). Urinary tract infection accompanied 113 operations (18% of primary and 9% of repeat), bowel complication 51 operations (7% of primary and 6% of repeat), fever 23 operations (4% of primary and 1% of repeat), wound complication 17 operations (3% of primary and 1% of repeat), and thromboembolism 11 operations (2% of primary and 0.3% of repeat). Patient age had no effect on the rate of complications. Pelvic and para-aortic lymphadenectomy in connection with primary operations caused substantial blood loss. Five subjects (1%) died after primary operations. On the whole, the surgical procedures, especially repeat operations, were well tolerated and should not be avoided for fear of complications.

    Malignant ovarian neoplasms represent the leading cause of death in gynecological malignancies. Although the majority of ovarian neoplasms occur in women of advanced years, ovarian neoplasms can occur in women of the reproductive age group. Preservation of fertility balanced with treatment of disease is the goal of young patients diagnosed with ovarian neoplasms. A new discipline termed "oncofertility" has emerged; however, several informational gaps exist. Concern has centered on the safety of conservative treatment, the uncertain efficacy of fertility options, the detrimental effects of chemotherapy to remaining reproductive organs, and the timing and execution of fertility workup relative to disease requiring treatment. This study involved an evaluation of young premenopausal women who underwent fertility-sparing surgery for an ovarian neoplasm. Given the rarity of this disease in premenopausal women the objective was to assess the feasibility of this study as defined by the completion rate of the survey. The aim was to broaden our knowledge of patient needs to partner with our survivorship clinic thereby ensuring that patients may facilitate their options. Patients were asked to complete a questionnaire titled Ovarian Cancer or Borderline Malignancy of the Ovary: Fertility Sparing Survey and a previously published instrument termed The Sexual Activity Questionnaire, a 21-item scale that assessed the impact of treatment on sexual functioning. All participants completed the survey illustrating the feasibility of the study. The study revealed that the majority of patients (91%) discussed fertility options with their clinicians, yet only 16% engaged in measures to preserve fertility. Patient's sexual interest and activity was maintained in this cohort of patients. This underscores the importance of continued studies in this unique population to ensure optimal fertility counseling and to better delineate the sexual well-being of young women diagnosed with ovarian

    Patients with two types of primary cancers are rare. In this study, we investigated the expression of p53, cyclin D1, and Ki-67 in the second primary malignancy. Tissue samples were obtained from the second primary cancer site of 43 patients who met the diagnostic criteria for double primary cancer. p53, cyclin D1 and Ki-67 were determined using immunohistochemistry. Categorical variables were compared using the Chi-squared test; correlation between data scores and histology was calculated using the Spearman's rank-order correlation. The expression rates of p53, cyclin D1 and Ki-67 in the second primary malignancy site were 60.5%, 30.2% and 65.1% respectively. p53 expression showed statistically significant association with tumor occurrence interval, pathological grading and nodal metastasis (p < 0.05). Positive correlation was detected between the expression of cyclin D1 and Ki-67 and the expression of p53 (r = 0.313, p = 0.041; r = 0.319, p = 0.037, respectively). High-expressing p53 or cyclin D second primary malignancies were associated with decreased overall survival (p = 0.040 and p = 0.043, respectively). Ki-67 expression levels did not exhibit statistically significant differences in survival. In conclusion, elevated protein expression of p53, cyclin D1 and Ki-67 in the second primary malignancy is an indicator of more aggressive malignant behavior of the secondary tumor. These markers may have prognostic value in the clinical setting. PMID:25120774

    Malignant melanoma is the third most common tumour to cause cerebral metastases, following breast and lung cancer. Central nervous system metastases occur in 10-40% of patients with melanoma. Intracranial metastasis from a primary malignant melanoma of the anterior mediastinum is uncommon. We report a case of solitary intracranial metastatic melanoma arising from a primary mediastinal tumour. We then discuss the clinico-radiological features and treatment options. PMID:27145991

    Malignant melanoma is characterized by the ability of diffuse metastases. Since the first report of an isolated malignant melanoma case of the gallbladder, it is already controversial whether isolated cases are metastatic or primary tumors. A 49-year-old woman appealed to the emergency unit because of abdominal pain. Ultrasonography revealed increased thickness of the gallbladder wall and a lesion with surrounding fluid sized 12 mm without acoustic shadow, which arose from the gallbladder wall and was consistent with a polyp. Histopathologic evaluation of the surgical specimen after laparoscopic cholecystectomy revealed malign epithelial tumor consisting of atypical cells with large eosinophilic cytoplasm and dense melanin pigment within the cytoplasm of the tumor cells. As no other focus was identified as a result of the evaluation, the patient was diagnosed with primary malignant melanoma of the gallbladder. In this paper, we aimed to define our treatment modality for a case with isolated malignant melanoma of the gallbladder. PMID:23094182

    An EGFR-expressing clone of the human ovarian cancer line 2774 was transfected with an antisense construct of EGFR to test how suppression of this gene modulates the malignant phenotype. Transfected clones were screened for EGFR expression by Western blot and FACS analysis. Anchorage-independent growth was used to assess the effect of reduced EGFR on the malignant behavior of the cells. Several transfected clones with decreased EGFR (40-50% reduction) were identified. A correlation was noted between reduced EGFR and decreased anchorage-independent growth, with the transfected clones losing the ability to grow in agarose and responsiveness to exogenous EGF. These results suggest that EGFR may be an important factor in the malignant behavior of this ovarian cancer cell line. PMID:9683849

    The occurrences of multiple primary malignant tumours in the head and neck region are reported as simultaneous, synchronous, or metachronous based on their chronology of presentation. Lymphoid malignancies presenting in association with squamous cell carcinoma in the head and neck region are extremely rare. We report a case of a 71 year old male patient with simultaneous triple primary malignancies of different histologic origin, involving larynx (squamous cell carcinoma), thyroid (papillary thyroid carcinoma) and lymph nodes (non-Hodgkin's lymphoma).

    Germ cell Tumours (GCT) are neoplasm derived from germ cells. GCT usually occurs inside the gonads. Extragonadal GCT’s are rare. Most common GCT associated with head and neck region are the teratomas. Of the few teratomas found in the head and neck, malignant transformation of a teratomatous element is very uncommon, and primary bone involvement within the head and neck is even rare. We present a case of primary malignant mixed germ cell Tumour involving the mandible, the present case presented malignant transformation of the epithelial component showing foci of squamous cell carcinoma within the GCT.

    Ovarian cancer is the deadliest gynecologic cancer. Receipt of treatment from a gynecologic oncologist is an evidence-based recommendation to reduce mortality from the disease. We examined knowledge and application of this evidence-based recommendation in primary care physicians as part of CDC gynecologic cancer awareness campaign efforts and discussed results in the context of CDC National Comprehensive Cancer Control Program (NCCCP). We analyzed primary care physician responses to questions about how often they refer patients diagnosed with ovarian cancer to gynecologic oncologists, and reasons for lack of referral. We also analyzed these physicians' knowledge of tests to help determine whether a gynecologic oncologist is needed for a planned surgery. The survey response rate was 52.2%. A total of 84% of primary care physicians (87% of family/general practitioners, 81% of internists and obstetrician/gynecologists) said they always referred patients to gynecologic oncologists for treatment. Common reasons for not always referring were patient preference or lack of gynecologic oncologists in the practice area. A total of 23% of primary care physicians had heard of the OVA1 test, which helps to determine whether gynecologic oncologist referral is needed. Although referral rates reported here are high, it is not clear whether ovarian cancer patients are actually seeing gynecologic oncologists for care. The NCCCP is undertaking several efforts to assist with this, including education of the recommendation among women and providers and assistance with treatment summaries and patient navigation toward appropriate treatment. Expansion of these efforts to all populations may help improve adherence to recommendations and reduce ovarian cancer mortality. PMID:26978124

    The behavior and genetics of serous epithelial ovarian cancer (EOC) metastasis, the form of the disease lethal to patients, is poorly understood. The unique properties of metastases are critical to understand to improve treatments of the disease that remains in patients after debulking surgery. We sought to identify the genetic and phenotypic landscape of metastatic progression of EOC to understand how metastases compare to primary tumors. DNA copy number and mRNA expression differences between matched primary human tumors and omental metastases, collected at the same time during debulking surgery before chemotherapy, were measured using microarrays. qPCR and immunohistochemistry validated findings. Pathway analysis of mRNA expression revealed metastatic cancer cells are more proliferative and less apoptotic than primary tumors, perhaps explaining the aggressive nature of these lesions. Most cases had copy number aberrations (CNAs) that differed between primary and metastatic tumors, but we did not detect CNAs that are recurrent across cases. A six gene expression signature distinguishes primary from metastatic tumors and predicts overall survival in independent datasets. The genetic differences between primary and metastatic tumors, yet common expression changes, suggest that the major clone in metastases is not the same as in primary tumors, but the cancer cells adapt to the omentum similarly. Together, these data highlight how ovarian tumors develop into a distinct, more aggressive metastatic state that should be considered for therapy development. PMID:24732363

    In this study, we characterized the metabolome of the human ovary and identified metabolic alternations that coincide with primary epithelial ovarian cancer (EOC) and metastatic tumors resulting from primary ovarian cancer (MOC) using three analytical platforms: gas chromatography mass spectrometry (GC/MS) and liquid chromatography tandem mass spectrometry (LC/MS/MS) using buffer systems and instrument settings to catalog positive or negative ions. The human ovarian metabolome was found to contain 364 biochemicals and upon transformation of the ovary caused changes in energy utilization, altering metabolites associated with glycolysis and β-oxidation of fatty acids—such as carnitine (1.79 fold in EOC, p<0.001; 1.88 fold in MOC, p<0.001), acetylcarnitine (1.75 fold in EOC, p<0.001; 2.39 fold in MOC, p<0.001), and butyrylcarnitine (3.62 fold, p<0.0094 in EOC; 7.88 fold, p<0.001 in MOC). There were also significant changes in phenylalanine catabolism marked by increases in phenylpyruvate (4.21 fold; p = 0.0098) and phenyllactate (195.45 fold; p<0.0023) in EOC. Ovarian cancer also displayed an enhanced oxidative stress response as indicated by increases in 2-aminobutyrate in EOC (1.46 fold, p = 0.0316) and in MOC (2.25 fold, p<0.001) and several isoforms of tocopherols. We have also identified novel metabolites in the ovary, specifically N-acetylasparate and N-acetyl-aspartyl-glutamate, whose role in ovarian physiology has yet to be determined. These data enhance our understanding of the diverse biochemistry of the human ovary and demonstrate metabolic alterations upon transformation. Furthermore, metabolites with significant changes between groups provide insight into biochemical consequences of transformation and are candidate biomarkers of ovarian oncogenesis. Validation studies are warranted to determine whether these compounds have clinical utility in the diagnosis or clinical management of ovarian cancer patients. PMID:21625518

    Four cases are documented where a glioma was histologically verified in the irradiation field of a previously treated malignancy of a different cell line. Radiation-induced neoplasia in the central nervous system now has been established in the induction of meningioma and sarcoma. The association between therapeutic irradiation and glioma in the reported cases lends to the evidence that a causal relation does exist. This incidence is small and does not detract from the overall benefit of irradiation as a therapeutic modality.

    Primary debulking surgery (PDS) followed by platinum-based chemotherapy has been the cornerstone of treatment for advanced ovarian cancer for decades. Primary debulking surgery has been repeatedly identified as one of the key factors in improving survival in patients with advanced ovarian cancer, especially when minimal or no residual disease is left behind. Achieving these results sometimes requires extensive abdominal and pelvic surgical procedures and consultation with other surgical teams. Some clinicians who propose a primary chemotherapy approach reported an increased likelihood of leaving no macroscopic disease after surgery and improved patient-reported outcomes and quality-of-life (QOL) measures. Given the ongoing debate regarding the relative benefit of PDS versus neoadjuvant chemotherapy (NACT), tumor biology may aid in patient selection for each approach. Neoadjuvant chemotherapy offers the opportunity for in vivo chemosensitivity testing. Studies are needed to determine the best way to evaluate the impact of NACT in each individual patient with advanced ovarian cancer. Indeed, the biggest utility of NACT may be in research, where this approach provides the opportunity for the investigation of predictive markers, mechanisms of resistance, and a forum to test novel therapies.

    Luteoma of pregnancy is a rare, tumorlike ovarian mass that develops during pregnancy and regresses after delivery. Generally, these masses are discovered incidentally during cesarean delivery or tubal ligation. Some of these patients will develop hirsutism or virilization during late pregnancy with or without fetal masculinization due to circulating androgens. The imaging features of this entity have been only rarely reported. An incidentally discovered luteoma of pregnancy in a 23-year-old patient during routine obstetric ultrasound is described and the image features in ultrasound and magnetic resonance (MR) imaging are discussed and compared with other studies. The patient underwent surgery to extract this mass considering the imaging findings were suspicious for neoplasia and the size and location could have potentially caused dystocia. This type of mass can mimic ovarian neoplasia and a correlation with imaging and laboratory findings can avoid an unnecessary surgical procedure during pregnancy. PMID:19243065

    Malignant germ cell tumors (MGCT) are a rare type of ovarian cancer with poorly understood behavior during pregnancy. This systematic review evaluated feto-maternal outcomes and management patterns of 102 ovarian MGCT-complicated pregnancies identified in PubMed/MEDLINE. Mean age was 25.8. The most common histology type was dysgerminoma (38.2%) followed by yolk sac tumor (30.4%). Abdomino-pelvic pain (35.3%) was the most common symptom. The majority were stage I disease (76.4%) with a mean tumor size of 17.9cm. Most cases had live births (77.5%) at term (56.6%). Tumor surgery without fetal conservation took place in 22 (21.6%) cases (Group 1). This group was characterized by the first trimester tumor detection and intervention, non-viable pregnancy, and frequent concurrent hysterectomy. There were 59 (57.8%) cases which underwent expectant management of pregnancy: mean delay 16.4 weeks for 46 (45.1%) cases with tumor surgery and fetal conservation (Group 2); and 7.8 weeks for 13 (12.7%) cases with tumor surgery after delivery (Group 3). The live birth rate in Groups 2 and 3 was 98.3%. There were 21 (20.6%) cases in which the tumor was incidentally found intra/postpartum (Group 4). Group 2 showed the highest 5-year overall survival rate (92.8%) followed by Group 4 (79.5%), Group 3 (71.4%), and Group 1 (56.2%, p=0.028). Group 1 had more advanced-stage disease when compared to Group 2 (proportion of stages II-IV disease, 36.4% versus 11.4%, p=0.023). In multivariate analysis, age ≤20 (p=0.032) and stages II-IV (p=0.02) remained independent prognosticators for decreased overall survival in all cases. Expectant management of pregnancy was not associated with poor survival outcome in multivariate analysis (p=0.43). In conclusion, our analysis demonstrated that timing of tumor intervention and delivery significantly impacted feto-maternal outcome of ovarian MGCT-complicated pregnancies. It is suggested that early detection and tumor intervention with expectant

    The objective of this study was to assess the potential predictive factors for follicle growth, ovulation, and pregnancy rate in patients with primary ovarian insufficiency/premature ovarian failure (POI/POF). We enrolled 25 POI patients with desired fertility who were treated and monitored for a minimum of 7 months between the years of 2000-2009 into this retrospective study. The clinical, endocrinologic, chromosomal, and autoimmunologic parameters of these patients were collected. Furthermore, hormonal backgrounds on each of 620 treatment cycles were investigated. The main outcome measures were follicle growth, ovulation, and pregnancy rate. Four of 25 patients (16%) conceived while being monitored and undergoing treatment. Follicle growth, ovulation, and pregnancy rate were not significantly different as a function of parity, iatrogenic history (e.g., chemotherapy), age of disease onset, serum estradiol (E(2))/follicle stimulating hormone (FSH) level at the time of diagnosis, chromosomal abnormality, and positive autoantibody titer. The serum E2 levels on days 1-5 of withdrawal bleeding (Day 1-5 E(2)) were significantly higher in the cycles with successful follicle growth and ovulation than unsuccessful cycles (P<0.05). Receiver-operator characteristic curve analysis revealed the cut-off value of the Day 1-5 E(2) to be 15.5 pg/mL, and an area under the curve (AUC) value of 0.674 for follicle growth and 0.752 for ovulation. The results suggest that cycles with a Day 1-5 E(2)≥15.5 pg/mL have a higher rate of follicle growth and ovulation in patients with POI. PMID:25312800

    We studied images and histopathological features of primary esophageal malignant melanoma to explore the clinical pathological features, diagnosis, differential diagnoses, and treatment. Immunolabelling was conducted on six cases of esophageal malignant melanoma using histological and immunohistochemical techniques. Combined with the related literature, the clinical manifestations, imaging, histopathological and immunohistochemical features, treatment, and prognosis of primary esophageal malignant melanoma were observed and analyzed. The six patients with primary esophageal malignant melanoma were all male with an average age of 63.4 years. Poor food intake was observed in all patients, and the symptoms showed progressive aggravation. Endoscopic feed tube revealed dark brown and black nodular and polypoid lesions, 1/4-1/2 loop cavity. Tumor histopathology revealed the following characteristics: tumor cells arranged in nests, sheets and cords, round or polygonal, abundant and red-stained cytoplasm, melanin granules in the cytoplasm, heterogeneous nucleus sizes, centered or deviated nuclei, clearly identifiable nucleoli, and apparent pathological mitosis. The immune phenotype was as follows: tumor cells had diffuse expression of HMB45, Melan A, and S100. The cells were CK negative, and the Ki67-positive cell number was 40%-45%. Primary esophageal malignant melanoma is rare with high malignancy and poor prognosis. Immunohistochemical staining is helpful for diagnosing this tumor. The differential diagnosis includes low differentiated carcinoma, primitive neuroectodermal tumor, esophageal sarcomatoid carcinoma, esophageal lymphoma, and other tumors. PMID:25400820

    Malignant mesothelioma (MM) is a highly-aggressive heterogeneous malignancy, typically diagnosed at advanced stage. An important area of mesothelioma biology and progression is understanding intercellular communication and the contribution of the secretome. Exosomes are secreted extracellular vesicles shown to shuttle cellular cargo and direct intercellular communication in the tumour microenvironment, facilitate immunoregulation and metastasis. In this study, quantitative proteomics was used to investigate MM-derived exosomes from distinct human models and identify select cargo protein networks associated with angiogenesis, metastasis, and immunoregulation. Utilising bioinformatics pathway/network analyses, and correlation with previous studies on tumour exosomes, we defined a select mesothelioma exosomal signature (mEXOS, 570 proteins) enriched in tumour antigens and various cancer-specific signalling (HPGD/ENO1/OSMR) and secreted modulators (FN1/ITLN1/MAMDC2/PDGFD/GBP1). Notably, such circulating cargo offers unique insights into mesothelioma progression and tumour microenvironment reprogramming. Functionally, we demonstrate that oncogenic exosomes facilitate the migratory capacity of fibroblast/endothelial cells, supporting the systematic model of MM progression associated with vascular remodelling and angiogenesis. We provide biophysical and proteomic characterisation of exosomes, define a unique oncogenic signature (mEXOS), and demonstrate the regulatory capacity of exosomes in cell migration/tube formation assays. These findings contribute to understanding tumour-stromal crosstalk in the context of MM, and potential new diagnostic and therapeutic extracellular targets. PMID:27605433

    Malignant immature ovarian teratomas (IOTs) most often occur in women of reproductive age. It is unclear, however, what roles estrogenic signaling plays in the development of IOT. In this study, we examined whether estrogen receptors (ERα and β) promote the cellular malignancy of IOT. Estradiol (E2), PPT (propylpyrazole), and DPN (diarylpropionitrile) (ERα- and β-specific agonists, respectively), as well as ERα- or ERβ-specific short hairpin (sh)RNA were applied to PA-1 cells, a well-characterized IOT cell line. Cellular tumorigenic characteristics, for example, cell migration/invasion, expression of the cancer stem/progenitor cell marker CD133, and evidence for epithelial-mesenchymal transition (EMT) were examined. In PA-1 cells that expressed ERα and ERβ, we found that ERα promoted cell migration and invasion. We also found that E2/ERα signaling altered cell behavior through non-classical transactivation function. Our data show non-genomic E2/ERα activations of focal adhesion kinase-Ras homolog gene family member A (FAK-RhoA) and ERK governed cell mobility capacity. Moreover, E2/ERα signaling induces EMT and overexpression of CD133 through upregulation micro-RNA 21 (miR21; IOT stem/progenitor promoter), and ERK phosphorylations. Furthermore, E2/ERα signaling triggers a positive feedback regulatory loop within miR21 and ERK. At last, expression levels of ERα, CD133, and EMT markers in IOT tissue samples were examined by immunohistochemistry. We found that cytosolic ERα was co-expressed with CD133 and mesenchymal cell markers but not epithelial cell markers. In conclusion, estrogenic signals exert malignant transformation capacity of cancer cells, exclusively through non-genomic regulation in female germ cell tumors. PMID:24142535

    OBJECTIVE: Ovarian mucinous metastases commonly present as the first sign of the disease and are capable of simulating primary tumors. Our aim was to investigate the role of intratumoral lymphatic vascular density together with other surgical-pathological features in distinguishing primary from secondary mucinous ovarian tumors. METHODS: A total of 124 cases of mucinous tumors in the ovary (63 primary and 61 metastatic) were compared according to their clinicopathological features and immunohistochemical profiles. The intratumoral lymphatic vascular density was quantified by counting the number of vessels stained by the D2-40 antibody. RESULTS: Metastases occurred in older patients and were associated with a higher proportion of tumors smaller than 10.0 cm; bilaterality; extensive necrosis; extraovarian extension; increased expression of cytokeratin 20, CDX2, CA19.9 and MUC2; and decreased expression of cytokeratin 7, CA125 and MUC5AC. The lymphatic vascular density was increased among primary tumors. However, after multivariate analysis, the best predictors of a secondary tumor were a size of 10.0 cm or less, bilaterality and cytokeratin 7 negativity. Lack of MUC2 expression was an important factor excluding metastasis. CONCLUSIONS: The higher intratumoral lymphatic vascular density in primary tumors when compared with secondary lesions suggests differences in the microenvironment. However, considering the differential diagnosis, the best discriminator of a secondary tumor is the combination of tumor size, laterality and the pattern of expression of cytokeratin 7 and MUC2.

    Currently available human tumour cell line panels consist of a small number of lines in each lineage that generally fail to retain the phenotype of the original patient tumour. Here we develop a cell culture medium that enables us to routinely establish cell lines from diverse subtypes of human ovarian cancers with >95% efficiency. Importantly, the 25 new ovarian tumour cell lines described here retain the genomic landscape, histopathology and molecular features of the original tumours. Furthermore, the molecular profile and drug response of these cell lines correlate with distinct groups of primary tumours with different outcomes. Thus, tumour cell lines derived using this methodology represent a significantly improved platform to study human tumour pathophysiology and response to therapy. PMID:26080861

    Currently available human tumour cell line panels consist of a small number of lines in each lineage that generally fail to retain the phenotype of the original patient tumour. Here we develop a cell culture medium that enables us to routinely establish cell lines from diverse subtypes of human ovarian cancers with >95% efficiency. Importantly, the 25 new ovarian tumour cell lines described here retain the genomic landscape, histopathology and molecular features of the original tumours. Furthermore, the molecular profile and drug response of these cell lines correlate with distinct groups of primary tumours with different outcomes. Thus, tumour cell lines derived using this methodology represent a significantly improved platform to study human tumour pathophysiology and response to therapy. PMID:26080861

    In embryonic stem (ES) cells, bivalent chromatin domains containing H3K4me3 and H3K27me3 marks silence developmental genes, while keeping them poised for activation following differentiation. We have identified gene sets associated with H3K27me3 and H3K4me3 marks at transcription start sites in a high-grade ovarian serous tumour and examined their association with epigenetic silencing and malignant progression. This revealed novel silenced bivalent marked genes, not described previously for ES cells, which are significantly enriched for the PI3K (P<10(-7)) and TGF-β signalling pathways (P<10(-5)). We matched histone marked gene sets to gene expression sets of eight normal fallopian tubes and 499 high-grade serous malignant ovarian samples. This revealed a significant decrease in gene expression for the H3K27me3 and bivalent gene sets in malignant tissue. We then correlated H3K27me3 and bivalent gene sets to gene expression data of ovarian tumour 'stem cell-like' sustaining cells versus non-sustaining cells. This showed a significantly lower expression for the H3K27me3 and bivalent gene sets in the tumour-sustaining cells. Similarly, comparison of matched chemo-sensitive and chemo-resistant ovarian cell lines showed a significantly lower expression of H3K27me3/bivalent marked genes in the chemo-resistant compared with the chemo-sensitive cell line. Our analysis supports the hypothesis that bivalent marks are associated with epigenetic silencing in ovarian cancer. However it also suggests that additional tumour specific bivalent marks, to those known in ES cells, are present in tumours and may potentially influence the subsequent development of drug resistance and tumour progression.

    We report a rare case of an intrathymic primary intrathoracic goiter. The patient with newly diagnosed breast carcinoma was also known to have a distinct large anterior mediastinal mass. This was removed via a median sternotomy, after a thorascopic biopsy had been performed in the past but a diagnosis had not been reached. A discussion relating to the extremely rare occurrence of intrathymic ectopic thyroid tissue and the surgical treatment of primary intrathoracic goiters is included. PMID:22269766

    Background: This research was conducted to introduce a patient with rare ovarian mixed germ cell tumor, presented as molar pregnancy. Case Presentation: The patient was a 16 year old woman admitted with diagnosis of molar pregnancy. Abdominal enlargement was the only complaint. She had a large pelvic mass in physical examination. The first diagnosis was molar pregnancy due to previous ultrasonic reports and positive βeta HCG. Urine pregnancy test was positive. As suction curettage was performed for her, surprisingly, the size of uterus was normal and no molar tissue was found in pathologic examination. At intraoperative ultrasound exam, an extra-uterine heterogeneous mass was found. Extra-uterine mass was confirmed by CT and MRI done after suction curettage. Mixed germ cell tumor was confirmed by histological examination after laparatomy and removing tumoral mass. Finally, she received Bleomycin, Etoposide and Cisplatin (BEP) regimen in four courses and Vincristine, Actinomycin D (Dactinomycin) and Cyclophosphamide (VAC) regimen in two courses and Diphereline for saving the other ovary. Conclusion: Some young patients misinterpret the early symptoms of an ovarian neoplasm as those of pregnancy which can lead to a delay in the diagnosis. PMID:27141469

    Ovarian cancer is a major cause of cancer mortality among women, largely due to late diagnosis of advanced metastatic disease. More extensive molecular analysis of metastatic ovarian cancer is needed to identify post-translational modifications of proteins, especially glycosylation that is particularly associated with metastatic disease to better understand the metastatic process and identify potential therapeutic targets. Glycoproteins in ascites fluid were enriched by affinity binding to lectins (ConA or WGA) and other affinity matrices. Separate glycomic, proteomic, and glycopeptide analyses were performed. Relative abundances of different N-glycan groups and proteins were identified from ascites fluids and a serum control. Levels of biomarkers CA125, MUC1, and fibronectin were also monitored in OC ascites samples by Western blot analysis. N-Glycan analysis of ascites fluids showed the presence of large, highly fucosylated and sialylated complex and hybrid glycans, some of which were not observed in normal serum. OC ascites glycoproteins, haptoglobin, fibronectin, lumican, fibulin, hemopexin, ceruloplasmin, alpha-1-antitrypsin, and alpha-1-antichymotrypsin were more abundant in OC ascites or not present in serum control samples. Further glycopeptide analysis of OC ascites identified N- and O-glycans in clusterin, hemopexin, and fibulin glycopeptides, some of which are unusual and may be important in OC metastasis.

    In vitro human prostate cell culture models are critical for clarifying the mechanism of prostate cancer progression and for testing preventive and therapeutic agents. Cell lines ideal for the study of human primary prostate tumors would be those derived from spontaneously immortalized tumor cells; unfortunately, explanted primary prostate cells survive only short-term in culture, and rarely immortalize spontaneously. Therefore, we recently have generated five immortal human prostate epithelial cell cultures derived from both the benign and malignant tissues of prostate cancer patients with telomerase, a gene that prevents cellular senescence. Examination of these cell lines for their morphologies and proliferative capacities, their abilities to grow in low serum, to respond to androgen stimulation, to grow above the agar layer, to form tumors in SCID mice, suggests that they may serve as valid, useful tools for the elucidation of early events in prostate tumorigenesis. Furthermore, the chromosome alterations observed in these immortalized cell lines expressing aspects of the malignant phenotypes imply that these cell lines accurately recapitulate the genetic composition of primary tumors. These novel in vitro models may offer unique models for the study of prostate carcinogenesis and also provide the means for testing both chemopreventive and chemotherapeutic agents.

    Primary glottic malignant melanoma of the larynx (PGMML) is a very rare clinical entity with less than 20 cases reported in the literature so far. The most frequently reported subsite in primary malignant melanomas of the larynx is the supraglottic larynx. The vocal cord as a subsite for primary malignant melanoma is very rare. The present case is a primary glottic malignant melanoma involving both vocal cords. PGMML may present early due to associated hoarseness of voice, unlike other non-cutaneous melanomas in the head and neck. Non-cutaneous malignant melanomas in the head and neck are historically very aggressive in nature and known for poor outcomes and survival. Most non-cutaneous melanomas described in the literature have been superficial spreading or ulcerative in nature, unlike the present case, in which proliferative, polypoidal growth was seen. No associated risk factor was present in this case. Every reported case of this rare entity further adds to the better understanding of tumour biology and expression. PMID:26590185

    Human amnion epithelial cells (hAECs) transplantation via tail vein has been reported to rescue ovarian function in mice with chemotherapy-induced primary ovarian insufficiency (POI). To test whether intraperitoneally transplanted hAECs could induce therapeutic effect and to characterize the paracrine effect of transplanted hAECs, we utilized a chemotherapy induced mice model of POI and investigated the ability of hAECs and conditioned medium collected from cultured hAECs (hAECs-CM) to restore ovarian function. We found that transplantation of hAECs or hAECs-CM either 24 hours or 7 days after chemotherapy could increase follicle numbers and partly restore fertility. By PCR analysis of recipient mice ovaries, the presence of SRY gene was only detected in mice transplanted with male hAECs 24 hours following chemotherapy. Further, the gene expression level of VEGFR1 and VEGFR2 in the ovaries decreased, although VEGFA increased 2 weeks after chemotherapy. After treatment with hAECs or hAEC-CM, the expression of both VEGFR1 and VEGFR2 increased, consistent with the immunohistochemical analysis. In addition, both hAECs and hAECs-CM treatment enhanced angiogenesis in the ovaries. The results suggested that hAECs-CM, like hAECs, could partly restore ovarian function, and the therapeutic function of intraperitoneally transplanted hAECs was mainly induced by paracrine-mediated ovarian protection and angiogenesis.

    The incidence, histologic distribution, and clinical manifestations of ovarian tumors in the pediatric population are distinct from those in adults. Although ovarian neoplasms in childhood and adolescence are rare, the diagnosis should be considered in young girls with abdominal pain and a palpable mass. Differential diagnosis in children and adolescents with ovarian tumors should be conducted on the basis of unique clinical manifestations, elevated serum tumor marker levels, and distinctive imaging findings. Although the clinical manifestations are nonspecific and may overlap, they may assist in diagnosis of some types of ovarian tumors. Children who present with a palpable mass or symptoms of precocious puberty have a high likelihood of malignancy. Many ovarian tumors are associated with abnormal hormonal activity and/or abnormal sexual development. Elevated levels of serum tumor markers, including α-fetoprotein, the beta subunit of human chorionic gonadotropin, and CA-125, raise concern for ovarian malignancies. However, negative tumor markers do not exclude the possibility of malignancy. Identification of imaging features at ultrasonography, computed tomography, and magnetic resonance imaging can help differentiate benign from malignant ovarian tumors and, in turn, plays a crucial role in determining treatment options. At imaging, malignant ovarian tumors usually appear predominantly solid or heterogeneous and are larger than benign tumors. Because surgery is the primary treatment for ovarian tumors, ovarian salvage with fertility preservation and use of a minimally invasive surgical technique are important in children and adolescents.

    A case is described of a 54 year old woman who had acute pericarditis with large exudative effusion accompanied by severe right and left ventricular failure. The patient was finally diagnosed with carcinoid heart disease from an ovarian carcinoid teratoma. She was treated with octreotide—a somatostatin analogue—followed by radical surgical resection of the neoplasm. At one year follow up only mild carcinoid tricuspid regurgitation remained. Only 16 cases of carcinoid heart disease from an ovarian primary have been described in literature. Moreover clinically manifest acute, non-metastatic pericarditis and left heart failure are not considered as possible presentations of carcinoid heart disease, whatever the origin. In a recent series a small pericardial effusion was considered an infrequent and unexpected echocardiographic finding in carcinoid heart patients. One case of "carcinoid pericarditis" has previously been described as a consequence of pericardial metastasis. Left sided heart involvement is usually caused by bronchial carcinoids or patency of foramen ovale; both were excluded in the case presented.

    This report describes the simultaneous occurrence of an ovarian teratoma and a granulosa cell tumor (GCT) with intra-abdominal metastasis in a 1.5 yr old female Doberman pinscher. At surgery, a 20 cm, smooth, intact mass associated with the left ovary and multiple 1-2 cm irregular masses in the broad ligament were found. The masses were surgically removed and submitted for histopathology. A histologic diagnosis of a teratoma and a GCT with broad ligament metastasis was made. Further treatment was elected by the owner and included two cycles of carboplatin therapy. The dog was euthanized 6 wk postoperatively for signs related to metastasis and dyspnea. Teratoma of the ovary, although it contains derivatives of all three embryonic germ cell layers, rarely presents together with either ovarian epithelial or sex cord-stromal tumors. To the authors' knowledge, this is the first reported case of an ovarian teratoma coexisting with a primary GCT with intra-abdominal metastasis in the same ovary in a dog. PMID:23033467

    Spontaneous 46,XX primary ovarian insufficiency (POI), also known as ‘premature menopause’ or ‘premature ovarian failure’, refers to ovarian dysfunction that results in a range of abnormalities, from infertility to early menopause as the end stage. The most common known genetic cause of POI is the expansion of a CGG repeat to 55–199 copies (premutation) in the 5′ untranslated region in the X-linked fragile X mental retardation 1 (FMR1) gene. POI associated with the FMR1 premutation is referred to as fragile X-associated POI (FXPOI). Here, we characterize a mouse model carrying the human FMR1 premutation allele and show that FMR1 premutation RNA can cause a reduction in the number of growing follicles in ovaries and is sufficient to impair female fertility. Alterations in selective serum hormone levels, including FSH, LH and 17β-estradiol, are seen in this mouse model, which mimics findings in humans. In addition, we also find that LH-induced ovulation-related gene expression is specifically altered. Finally, we show that the FMR1 premutation allele can lead to reduced phosphorylation of Akt and mTOR proteins. These results together suggest that FMR1 premutation RNA could cause the POI associated with FMR1 premutation carriers, and the Akt/mTOR pathway may serve as a therapeutic target for FXPOI.

    Patients with squamous cell cancer (SCC) of the head and neck are at increased risk for second primary malignancies (SPMs). We report on a 53-year-old patient with primary diagnosis of SCC in the anterior floor of the mouth. Panendoscopy suspected an SPM of the right vocal cord. FDG PET/CT, as a whole-body imaging method, confirmed this suspicion and raised concern for further SPM of both esophagus and colon. All malignancies were confirmed by biopsy. Subsequently, the patient underwent radiochemotherapy. In summary, FDG PET/CT revealed unexpected multiple SPMs, prevented unnecessary resection of the oral SCC, and enabled individualized therapeutic management. PMID:25742223

    Despite the increasing understanding of female reproduction, the molecular diagnosis of primary ovarian insufficiency (POI) is seldom obtained. The RNA-binding protein NANOS3 poses as an interesting candidate gene for POI since members of the Nanos family have an evolutionarily conserved function in germ cell development and maintenance by repressing apoptosis. We performed mutational analysis of NANOS3 in a cohort of 85 Brazilian women with familial or isolated POI, presenting with primary or secondary amenorrhea, and in ethnically-matched control women. A homozygous p.Glu120Lys mutation in NANOS3 was identified in two sisters with primary amenorrhea. The substituted amino acid is located within the second C2HC motif in the conserved zinc finger domain of NANOS3 and in silico molecular modelling suggests destabilization of protein-RNA interaction. In vitro analyses of apoptosis through flow cytometry and confocal microscopy show that NANOS3 capacity to prevent apoptosis was impaired by this mutation. The identification of an inactivating missense mutation in NANOS3 suggests a mechanism for POI involving increased primordial germ cells (PGCs) apoptosis during embryonic cell migration and highlights the importance of NANOS proteins in human ovarian biology.

    Ovarian cancer represents an aggressive gynecological malignancy with a high capacity for dissemination. Once the tumor cells go beyond the pelvic area, upper abdominal involvement, including hepatic, diaphragmatic or even splenic, is frequently seen. The aim of the present study was to determine the impact on survival of parenchymatous versus peritoneal splenic metastases versus splenic hilum lymph node involvement at the time of primary cytoreduction for advanced-stage epithelial ovarian cancer. Sixty-six patients with a mean age of 54.12 years (range=25-80 years) were submitted to splenectomy in the context of primary cytoreduction at the Dan Setlacec Center of Gastrointestinal Disease and Liver Transplantation, Fundeni Clinical Institute, between January 2002 and May 2014. Although complete macroscopic resection was attempted in all cases, an R0 resection was achieved only in 57 out of the 66 cases. Histopathological studies confirmed the presence of serous subtype in 61 cases, while in the other five cases, the mucinous subtype was found. When studying the specimens of splenectomy, capsular invasion was found in 35 cases (53%), parenchymatous involvement was present in 19 (28.7%), and hilar involvement was present in 12 (18.1%). The overall morbidity rate was 30%, while the 30-day postoperative mortality rate was 7%. The median overall survival for cases with peritoneal seeding was 58.4 months, while that for patients with parenchymatous involvement was 24.5 months (p=0.0126); patients diagnosed with hilar involvement had a median overall survival of 40.6 months (p=0.362). In conclusion, the presence of parenchymatous splenic metastases at primary cytoreduction for advanced-stage ovarian cancer is associated with significantly poorer survival when compared to hilar or peritoneal seeding.

    Primary oral malignant melanoma, very rare neoplasm of melanocytic origin, usually presents as a bluish black to tan-brown colored lesion Which is accounting for 0.2 to 8% of all melanomas, 1.6% of all head and neck malignancies, and 0.5% of all oral neoplasia. In general, the prognosis of oral melanoma is poor and worse than that of cutaneous melanoma. Here a case of oral malignant melanoma is presented, which was undetected during the first visit to a dental clinic. When a simple oral surgical treatment was carried out in that region, it resulted in the appearance of a massive pigmented lesion which was histopathologically diagnosed as malignant melanoma. This paper is presented to reemphasize the fact that any pigmented lesion in the oral cavity should be viewed with suspicion and proper investigation (biopsy) should be carried out to rule out any untoward experiences later.

    Primary intracranial melanomas are rare and occur mainly in young adults. Originating from leptomeningeal melanoblasts and extending into the parenchyma, the tumours closely resemble meningiomas, from which they are radiologically difficult to distinguish despite progress in neuroimaging. Definitive diagnosis is usually made on histopathological examination, though confirmed only after post-mortem examination in some cases. Prolonged disease-free periods, and in rare cases long-term survival, are possible following successful total surgical excision. This case presented with typical clinical features but, at 79 years old, an unusual age. PMID:9894390

    Out of 403 patients with ovarian with malignancies during 1978 to, 1985, 117 (29.0%) died from the progression of a non-curative cancer (56 cases, 47.9%) or from a cancer recurrence (61 cases, 52.1%). The mean survival rate 117 cases was 13.4 months, of which 103 (88.0%) cases concerned patients who died within 2 years and 114 (97.4%) who died within 3 years. A histological analysis revealed that patients with a serous or an endometrial cancer had a longer survival rate than others. Among 61 recurrent cases, 59 (96.7%) fell into recurrence within 2 years. Regarding the relationship between a recurrent of cancer and its prognosis, patients with a recurrence of an ascitic or a metastatic disease had a poorer prognosis than patients with a pelvic or an abdominal mass. An aggressive operation, such as a resection of a recurrent tumor, even if small in volume, led to a better prognostic result than no therapy. PMID:3694804

    Background Ovarian cancer tends to be chemosensitive and confine itself to the surface of the peritoneal cavity for much of its natural history. These features have made it an obvious target for intraperitoneal (IP) chemotherapy. Chemotherapy for ovarian cancer is usually given as an intravenous (IV) infusion repeatedly over five to eight cycles. Intraperitoneal chemotherapy is given by infusion of the chemotherapeutic agent directly into the peritoneal cavity. There are biological reasons why this might increase the anticancer effect and reduce some systemic adverse effects in comparison to IV therapy. Objectives To determine if adding a component of the chemotherapy regime into the peritoneal cavity affects overall survival, progression-free survival, quality of life (QOL) and toxicity in the primary treatment of epithelial ovarian cancer. Search methods We searched the Gynaecological Cancer Review Group’s Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 2, 2011, MEDLINE (1951 to May 2011) and EMBASE (1974 to May 2011). We updated these searches in February 2007, August 2010 and May 2011. In addition, we handsearched and cascade searched the major gynaecological oncology journals. Selection criteria The analysis was restricted to randomised controlled trials (RCTs) assessing women with a new diagnosis of primary epithelial ovarian cancer, of any FIGO stage, following primary cytoreductive surgery. Standard IV chemotherapy was compared with chemotherapy that included a component of IP administration. Data collection and analysis We extracted data on overall survival, disease-free survival, adverse events and QOL and performed meta-analyses of hazard ratios (HR) for time-to-event variables and relative risks (RR) for dichotomous outcomes using RevMan software. Main results Nine randomised trials studied 2119 women receiving primary treatment for ovarian cancer. We considered six trials to be of high quality. Women were less

    Background. Malignant melanoma could present with metastasis with unknown primary (MUP) and this happens in 2-3% according to the studies. Around 90% of melanomas have cutaneous origin, but still there are melanomas that could be found in visceral organs or lymph nodes with unknown primary site. Spontaneous regression of the primary site could be an explanation. Case Report. We report a 58-year-old Caucasian male who presented with a right sided swelling in the inguinal region. Surgery was performed and biopsy showed metastatic malignant melanoma. No cutaneous lesions were identified by history or physical examination. Work up could not detect the primary lesion and patient was started on radiotherapy and immunotherapy. Conclusion. We present a case of malignant melanoma of unknown primary presenting in an unusual place which is the inguinal lymph node. Theories try to explain the pathway of development of such tumors and one of the theories mentions that it could be a spontaneous regression of the primary cutaneous lesion. Another theory is that it could be from transformation of aberrant melanocyte within the lymph node. Prognosis is postulated to be better in this case than in melanoma with a known primary.

    Background Malignant myoepithelioma is a relatively rare malignant tumor occurring most frequently in the salivary glands. A few isolated cases have been described in other locations, including soft tissue, bone, lung, bronchus, oral cavity, nasopharynx, larynx, and maxillary sinus. Malignant myoepithelioma, however, is uncommonly involved within the cavernous sinus. To the best of our knowledge, this is the first report of malignant myoepithelioma arising from within the cavernous sinus. Case presentation Herein, we report a case of a 48-year-old woman who presented a 1-month history of diplopia and blepharoptosis as well as radiological evidence of a rapidly developing cavernous sinus tumor. The patient underwent a trans-sphenoidal biopsy and a histological diagnosis indicated a malignant myoepithelioma. After diagnosis, the tumor grew rapidly and her clinical condition deteriorated progressively. Therefore, a pterional craniotomy with partial tumor removal was performed. The patient’s clinical state was worsened, and she died two months after the initial operation. Because the malignant myoepithelioma could not be traced to an organ of origin, other than the cavernous sinus, this case was diagnosed as a primary intracranial malignant myoepithelioma. Conclusion The purpose of presenting this case report is to raise awareness among clinicians to consider malignant myoepithelioma as a differential diagnosis when a cavernous sinus mass is identified. Furthermore, an ideal management strategy for malignant myoepithelioma is not known and the prognosis seems to be unfavorable; therefore, more cases are needed to enhance our knowledge of the diagnosis, treatment, and prognosis of this rare intracranial lesion.

    Primary ovarian insufficiency (POI), also known as premature ovarian failure (POF), is defined as more than six months of cessation of menses before the age of 40 years, with two serum follicle stimulating hormone (FSH) levels (at least 1 month apart) falling in the menopause range. The cause of POI remains undetermined in the majority of cases, although some studies have reported increased levels of reactive oxygen species (ROS) in idiopathic POF. The role of mitochondrial DNA in the pathogenesis of POI has not been studied extensively. This aim of this study was to uncover underlying mitochondrial genetic defects in patients with POI. The entire region of the mitochondrial genome was amplified in subjects with idiopathic POI (n=63) and age-matched healthy female controls (n=63) using nine pair sets of primers, followed by screening of the mitochondrial genome using an Illumina MiSeq. We identified a total of 96 non-synonymous mitochondrial variations in POI patients and 93 non-synonymous variations in control subjects. Of these, 21 (9 in POI and 12 in control) non-synonymous variations had not been reported previously. Eight mitochondrial cytochrome coxidase 1 (MT-CO1) missense variants were identified in POI patients, whereas only four missense mutations were observed in controls. A high incidence of MT-CO1 missense variants were identified in POI patients compared with controls, and the difference between the groups was statistically significant (13/63 vs. 5/63, p=0.042). Our results show that patients with primary ovarian insufficiency exhibit an increased incidence of mitochondrial cytochrome c oxidase 1 gene mutations, suggesting that MT-CO1 gene mutation may be causal in POI.

    HFM1 is a meiosis-specific gene and expressed in germ-line tissues. More recently, evidence has indicated that variations in HFM1 gene could be causative for primary ovarian insufficiency (POI), also known as premature ovarian failure. The aim of this study was to investigate the association between HFM1 gene variants and sporadic POI in Chinese women. A total of 138 POI patients and 316 healthy controls (matched for ethnic background, sex, and age of the patients) were recruited in this study. We screened the entire HFM1 coding region by direct sequencing in all subjects and identified six variants of HFM1 gene in POI group, namely c.148G>A/p.Glu50Lys, c.1241A>C/p.His414Pro, c.2325C>A/p.Phe775Leu, c.3367T>C/p.Ser1123Pro, c.3580C>T/p.Arg1194Cys, and c.1686-1G>C. The variation rate of HFM1 in POI group is significantly higher than control group (p < 0.01). The p.His414Pro and p.Arg1194Cys were predicted to be probably damaging to the HFM1 protein function, while p.Glu50Lys, p.Phe775Leu and p.Ser1123Pro mutants might not have any deleterious effect on the structure or function of the protein by online predictors. Taken together, our data suggested that HFM1 gene might be associated with primary ovarian insufficiency in Chinese population. PMID:26679638

    Malignant ascites (MA) is most commonly observed in patients scheduled for epithelial ovarian cancer (EOC) surgery and is supposed as a major risk factor promoting perioperative hemodynamic deterioration. We aimed to assess the hemodynamic consequences of MA on systemic circulation in patients undergoing cytoreductive EOC surgery.This study is a predefined post-hoc analysis of a randomized controlled pilot trial comparing intravenous solutions within a goal-directed algorithm to optimize hemodynamic therapy in patients undergoing cytoreductive EOC surgery. Ascites was used to stratify the EOC patients prior to randomization in the main study. We analyzed 2 groups according to the amount of ascites (NLAS: none or low ascites [<500 mL] vs HAS: high ascites group [>500 mL]). Differences in hemodynamic variables with respect to time were analyzed using nonparametric analysis for longitudinal data and multivariate generalized estimating equation adjusting the analysis for the randomized study groups of the main study.A total of 31 patients in the NLAS and 16 patients in the HAS group were analyzed. Although cardiac output was not different between groups suggesting a similar circulatory blood flow, the HAS group revealed higher heart rates and lower stroke volumes during surgery. There were no differences in pressure-based hemodynamic variables. In the HAS group, fluid demands, reflected by the time to reindication of a fluid challenge after preload optimization, increased steadily, whereas stroke volume could not be maintained at baseline resulting in hemodynamic instability after 1.5 h of surgery. In contrast, in the NLAS group fluid demands were stable and stroke volume could be maintained during surgery. Clinically relevant associations of the type of fluid replacement with hemodynamic consequences were particularly observed in the HAS group, in which transfusion of fresh frozen plasma (FFP) was associated to an improved circulatory flow and reduced

    CD4(+)CD25(+) T cells are critical for maintenance of immunologic self-tolerance. We measured the number of CD4(+)CD25(+) cells in the patients with primary malignant hypertension related kidney injury, to explore the molecular pathogenesis of this disease. We selected 30 patients with primary malignant hypertension related kidney injury and 30 healthy volunteers. Information on clinical characteristics and laboratory tests was obtained from each subject. The number of CD4(+)CD25(+) cells and glomerular injury were assessed by flow cytometry and histopathology, respectively. Both serum IL-2, IL-4, and IL-6 and endothelial cell markers were analyzed by ELISA. ADAMTS13 antibody was detected by Western blotting. CD4(+)CD25(+) cells were significantly reduced in patients with primary malignant hypertension related kidney injury compared to controls (P < 0.05). The number of CD4(+)CD25(+) cells was negatively related to blood urea nitrogen, serum uric acid, proteinuria, and supernatant IL-4; whereas positively associated with estimated glomerular filtration rate in patients. Gradually decreasing CD4(+)CD25(+) cells were also found as increasing renal injury. Additionally, patients exhibited increasing supernatant IL-4, serum IL-2 and IL-6, endothelial cell markers, and anti-ADAMTS13 antibody compared with controls (all P < 0.05). CD4(+)CD25(+) cells may play a key role in the pathogenesis of primary malignant hypertension related kidney injury. PMID:27278520

    Multiple primary carcinoma (MPC) is defined as two or more carcinomas without subordinate relationship detected in the same or other organs of an individual patient. The diagnosis of MPC must comply with the following standards: each of the tumors must present a definite picture of malignancy, each tumor must be histologically distinct, and the probability of one being a metastasis of the other must be excluded. MPC often occurs in the digestive system, but its pathogenesis remains unclear involving genetic susceptibility, tumor immunity and iatrogenic factors, including radiotherapy and chemotherapy. Most MPC patients are double primary malignancy; the occurrence of quadruple primary malignancy is below 0.1%. Here we present a rare case of quadruple primary malignancy involving the small intestine, descending colon, renal pelvis and pancreas. Due to its rarity, the relevant literature is also reviewed. In general, the incidence of MPC is rising, so prevention, early diagnosis and treatment will become necessary and important. Therefore, further research should focus on the etiology and mechanism of MPC. PMID:23538731

    Patients with aggressive musculoskeletal tumours often arrive at specialised treatment centres late. Such a delay could mean disfavour for potentially curable or long-term disease-free outcome of limb preserving surgery. This study was undertaken to identify the underlying problem-related delay with a view to propose solution for solving it. We reviewed 30 patients to determine the periods of delay between onset of the first symptom and the definitive treatment. The delays were categorized as 'patient' delay, 'referral' delay and 'treatment' delay. There was 'patient' delay in 57% of patients (n=17), ranging from 1 to 18 months; 'referral' delay in 67% of patients (n=20) ranging from 1 to 19 months and 23% of patients (n=7) had treatment delay (average 23 days) at the treatment centre. The causes of late arrival are not solely patient-related but are multifactorial. Measures to minimize such delays include enhancing awareness only with high index of suspicion among primary care practitioners, creating a special lane specialized imaging studies and establishing a dedicated musculoskeletal tumour unit.

    Between June 1976 and January 1986, 94 evaluable patients with stage I-IV disease underwent second-look laparotomy as part of their treatment for ovarian epithelial carcinomas. Stage and residual tumor size after initial debulking surgery demonstrated a significant association with absence of disease at reexploration. Forty-nine patients (52%) had no evidence of disease at second-look laparotomy. Thirty patients (32%) had macroscopic residual tumor, and 15 patients (16%) had microscopic disease at reexploration. Patients with a negative second-look laparotomy had an excellent prognosis; uncorrected 2- and 5-year survival rates exceed 90%. None of the patients with stage I or II disease developed recurrent tumor after a negative second-look laparotomy. However, 7 of the 25 (28%) patients with stage III disease and a negative second-look have demonstrated recurrent carcinomas. Recurrences were documented from 15.4 to 51.7 months after second-look laparotomy and were located within the abdominal cavity. Life table methods demonstrated improved survival for patients with microscopic disease as compared to those with gross tumor at second-look survey. Both groups had similar mean patient ages and tumor stage distributions. Patients with microscopic residual disease had uncorrected 2- and 5-year survival rates of 76 and 64%. The 2-year uncorrected survival rate for patients with gross tumor at second-look laparotomy was 25%. Thirty patients with macroscopic disease at second-look laparotomy underwent a repeat attempt at tumor debulking. Seventeen patients completed second-look surgery with residual disease less than 1 cm in maximum dimensions. Life table methods demonstrated improved survival when residual disease was less than 1 cm. Regardless of residual tumor size after reexploration, patients with gross tumor had a worse survival than those with microscopic disease. PMID:3666578

    The incidence of second primary malignancies (SPMs) in Japanese patients with myeloma or myeloma-related diseases was studied by using the Kansai Myeloma Forum (KMF) database registered from November 2012 to March 2015. We studied 1,571 cases. Hematologic malignancies were documented in 10 patients, and solid tumors in 36 during this period. The cumulative 5-year incidence was estimated to be 1.0% for hematological malignancies and 3.7% for solid tumors. In the patients with smoldering myeloma or MGUS without treatment, solid tumors but not hematologic malignancies developed, though the cumulative incidence of each malignancy did not differ significantly from that in patients receiving treatment. Although statistical analysis showed that treatment with melphalan, bortezomib, lenalidomide, or thalidomide had no effect on the occurrence of hematological malignancies, lenalidomide administration was more frequent in the patients with solid tumors. To evaluate the SPMs in myeloma or myeloma-related diseases more accurately, accumulation of a larger number of patients and longer observation are needed. PMID:27498726

    Recent findings on the molecular basis of ovarian cancer development and progression create new opportunities to develop anticancer medications that would affect specific metabolic pathways and decrease side systemic toxicity of conventional treatment. Among new possibilities for cancer chemoprevention, much attention is paid to curcumin—A broad-spectrum anticancer polyphenolic derivative extracted from the rhizome of Curcuma longa L. According to ClinicalTrials.gov at present there are no running pilot studies, which could assess possible therapeutic benefits from curcumin supplementation to patients with primary epithelial ovarian cancer. Therefore, the goal of this review was to evaluate potential preclinical properties of curcumin and its new analogues on the basis of in vivo and in vitro ovarian cancer studies. Curcumin and its different formulations have been shown to display multifunctional mechanisms of anticancer activity, not only in platinum-resistant primary epithelial ovarian cancer, but also in multidrug resistant cancer cells/xenografts models. Curcumin administered together with platinum-taxane chemotherapeutics have been reported to demonstrate synergistic effects, sensitize resistant cells to drugs, and decrease their biologically effective doses. An accumulating body of evidence suggests that curcumin, due to its long-term safety and an excellent profile of side effects should be considered as a beneficial support in ovarian cancer treatment strategies, especially in patients with platinum-resistant primary epithelial recurrent ovarian cancer or multidrug resistant disease. Although the prospect of curcumin and its formulations as anticancer agents in ovarian cancer treatment strategy appears to be challenging, and at the same time promising, there is a further need to evaluate its effectiveness in clinical studies.

    Our presentation illustrates a rare case of primary renal pelvis malignant melanoma in a 35-year-old man. The diagnosis of malignant melanoma was based on immunophenotype and the detection of intracellular melanin pigment. The renal origin was proven by the presence of scattered melanocytes within the urothelium of the pelvis. The tumor exhibited extensive clear cell change that closely mimics clear cell renal cell carcinoma. The patient’s clinical history did not disclose any signs of previous melanocytic skin or mucosa lesions. Differential diagnosis includes tumors capable of synthesizing melanin or expressing melanocytic markers. PMID:27226943

    A 35-year-old woman underwent laparoscopic radical hysterectomy, pelvic lymphadenectomy and ovarian transposition for stage IB2 cervical adenocarcinoma. She received adjuvant concurrent chemoradiation for poor pathologic risk factors but had tumor recurrence 20 months after the surgery. Transposed ovaries were uninvolved in the recurrence and progression. Salvage chemotherapy and radiotherapy were given. Despite systemic chemotherapy and repeat pelvic radiotherapy, the patient was able to maintain ovarian function. Ovarian transposition in cervical cancer is an easily performed procedure that does not alter the prognosis of the disease in some cases. Present recommendations for its use should be reevaluated so that more premenopausal cancer patients may benefit from this underutilized procedure. PMID:23653838

    Malignant melanoma is one of the most aggressive and treatment resistant skin cancers. India enjoys a low incidence of melanoma, and age specific incidence rates for cutaneous malignant melanoma (CMM) are being less than 0.5 per 1,000,000. This could be due to under-reporting of melanoma on account of a low index of suspicion by clinicians and pathologists alike. Most common site for origin of primary melanoma is skin, accounting for about 91.2% of all reported primary malignant melanoma cases. Other primary sites are relatively uncommon. Primary pleural melanoma is a very rare tumor and to the best of our knowledge, only seven cases have been reported so far worldwide. We hereby discuss a new case, only second from India. Our patient also had coexistent congenital hairy nevus, an unusual association also noted in two previously reported cases. Excluding primary cutaneous melanoma with pleural metastasis was a diagnostic challenge in this case but multiple cutaneous biopsies together with clinical and findings helped us arrive at this unusual diagnosis. Unfortunately, the patient succumbed to his illness. Diagn. Cytopathol. 2016;44:648-652. © 2016 Wiley Periodicals, Inc. PMID:27164972

    Primary ovarian insufficiency (POI) results in an early loss of ovarian function, and remains idiopathic in about 80% of cases. Here, we have performed a complete genetic study of a consanguineous family with two POI cases. Linkage analysis and homozygosity mapping identified 12 homozygous regions with linkage, totalling 84 Mb. Whole-exome sequencing of the two patients and a non-affected sister allowed us to detect a homozygous causal variant in the MCM9 gene. The variant c.1483G>T [p.E495*], confirmed using Sanger sequencing, introduced a premature stop codon in coding exon 8 and is expected to lead to the loss of a functional protein. MCM9 belongs to a complex required for DNA repair by homologous recombination, and its impairment in mouse is known to induce meiotic recombination defects and oocyte degeneration. A previous study recently described two consanguineous families in which homozygous mutations of MCM9 were responsible for POI and short stature. Interestingly, the affected sisters in the family described here had a normal height. Altogether, our results provide the confirmation of the implication of MCM9 variants in POI and expand their phenotypic spectrum. PMID:26771056

    The treatment of ovarian cancer principally relies on the use of platinum and taxane chemotherapeutic agents. Short-term clinical results have been encouraging, but long-term responses remain limited. In this report, an in vitro assay system that utilizes cells grown from human tumor explants has been used to quantitatively evaluate responses to relevant concentrations of alternative chemotherapeutic agents. The results suggest that there are significant differences in the responses of explant-derived cultured cells to the different agents tested. In an evaluation of 276 primary ovarian cancer specimens, five nonstandard drugs were tested in 51 cases. Of these 51 cases, cyclophosphamide had the highest rate of response at 67%, followed by doxorubicin at 61%, gemcitabine at 49%, etoposide at 48%, and topotecan at 14%. Venn diagrams, representing the in vitro responses to the platins and taxanes, as well as the responses to the nonstandard drugs, illustrate that there clearly are distinct differences among patients in a given population. These data underscore the potential importance of evaluating each patient's response to a number of different drugs to optimize the therapeutic decision-making process. PMID:15304154

    The purpose of this study was to determine the primary patency of two or more noncoaxial self-expanding metallic Wallstents (Boston Scientific, Natick, MA) and to compare this with the primary patency of a single stent in malignant bile duct obstruction. From August 2002 to August 2004, 127 patients had stents placed for malignant bile duct obstruction. Forty-five patients were treated with more than one noncoaxial self-expanding metallic stents and 82 patients had a single stent placed. Two patients in the multiple-stent group were lost to follow-up. The primary patency period was calculated from the date of stenting until the first poststenting intervention for stent occlusion, death, or the time of last documented follow-up. The patency of a single stent was significantly different from that of multiple stents (P = 0.0004). In the subset of patients with high bile duct obstruction, the patency of a single stent remained significantly different from that of multiple stents (P = 0.02). In the single-stent group, there was no difference in patency between patients with high vs. those with low bile duct obstruction (P = 0.43). The overall median patency for the multistent group and the single-stent group was 201 and 261 days, respectively. In conclusion, the patency of a single stent placed for malignant low or high bile duct obstruction is similar, and significantly longer than, that of multiple stents placed for malignant high bile duct obstruction. Given the median patency of 201 days, when indicated, percutaneous stenting of multiple bile ducts is an effective palliative measure for patients with malignant high bile duct obstruction.

    In rare cases, primary malignant lymphomas may arise in the soft tissues. Only one previous case has arisen in the context of chronic lymphedema. Because of the clinical appearance of such lesions, which resemble violaceous nodular or plaquelike tumors, they may be confused clinically with lymphedema-associated angiosarcomas occurring after radical mastectomy (Stewart-Treves syndrome). Furthermore, the histologic appearance of some lymphomas and angiosarcomas may also be similar. We studied two women with primary postmastectomy lymphedema-related malignant lymphoma in the soft tissues of the upper arm. These tumors arose 11 and 30 years, respectively, after radical removal of ductal mammary carcinomas. Histologically, one neoplasm mimicked metastatic carcinoma or epithelioid angiosarcoma; whereas the other was initially confused with a variety of pathologic entities, including vasculitis, epithelioid hemangioma, and malignant fibrous histiocytoma. The lymphoid nature of both lesions was confirmed by immunoreactivity for leukocyte common antigen in addition to the B-lymphocyte marker, L26. Conversely, vascular and epithelial determinants were absent. One patient's disease pursued an indolent course; she died of unknown causes but with no evidence of lymphoma at last follow-up. The second patient is currently in remission on chemotherapy. Awareness of the existence of lymphedema-related malignant lymphoma and familiarity with methods used for its distinction from epithelioid vascular sarcomas should prevent unnecessary surgery.

    Malignant ascites is a common complication in the late stages of epithelial ovarian cancer (EOC) that greatly diminishes the quality of life of patients. Malignant ascites is a known consequence of vascular dysfunction, but current approved treatments are not effective in preventing fluid accumulation. In this study, we investigated an alternative strategy of targeting macrophage functions to reverse the vascular pathology of malignant ascites using fluid from human patients and an immunocompetent murine model (ID8) of EOC that mirrors human disease by developing progressive vascular disorganization and leakiness culminating in massive ascites. We demonstrate that the macrophage content in ascites fluid from human patients and the ID8 model directly correlates with vascular permeability. To further substantiate macrophages' role in the pathogenesis of malignant ascites, we blocked macrophage function in ID8 mice using a colony-stimulating factor 1 receptor kinase inhibitor (GW2580). Administration of GW2580 in the late stages of disease resulted in reduced infiltration of protumorigenic (M2) macrophages and dramatically decreased ascites volume. Moreover, the disorganized peritoneal vasculature became normalized and sera from GW2580-treated ascites protected against endothelial permeability. Therefore, our findings suggest that macrophage-targeted treatment may be a promising strategy toward a safe and effective means to control malignant ascites of EOC. PMID:26471360

    The treatment of benign and malignant primary bone tumors has progressed over time from relatively simple practice to complex resection and reconstruction techniques. Recently, computer-assisted orthopaedic surgery (CAOS) has been used to assist surgeons to enhance surgical precision in order to achieve these goals. Initially, software developed for CT-based spinal applications was used to perform simple intraoperative point localization. With advances in technique and software design, oncology surgeons have now performed joint sparing complex multiplanar osteotomies using combined CT and MRI image data with precision and accuracy. The purpose of this paper is to provide a review of the clinical progress to date, the different types of navigation available, methods for error management, and limitations of CAOS in the treatment of pediatric benign and malignant primary bone tumors.

    Summary Primary ovarian insufficiency (POI) is the condition of intermittent or permanent gonadal insufficiency that occurs in women before the age of 40. We describe three cases of POI referred to the outpatient endocrinology clinic of a university hospital. The three patients met diagnostic criteria for POI and were managed by specific approaches tailored to individualized goals. In the first case, the main concern was fertility and the reproductive prognosis. The second patient was a carrier of a common genetic cause of POI: premutation of the FMR1 gene. The third case was a patient diagnosed with a POI and established osteoporosis, a common complication of estrogen deprivation. This study reports the treatment and follow-up of these cases, with an emphasis on relevant aspects of individualized management, alongside a brief literature review. Learning points A diagnosis of POI should be considered in patients presenting with amenorrhea or irregular menses and high serum follicle-stimulating hormone (FSH) levels before age 40 years. Patients with POI without an established cause, especially in familial cases, should be tested for FMR1 mutations. Estrogen/progestin replacement therapy is indicated since diagnosis until at least the estimated age of menopause, and is the cornerstone for maintaining the good health of breast and urogenital tract and for primary or secondary osteoporosis prevention in POI. Fertility should be managed through an individualized approach based on patient possibilities, such as egg or embryo donation and ovarian cryopreservation; pregnancy can occur spontaneously in a minority of cases. Women with POI should be carefully monitored for cardiovascular risk factors. PMID:27252868

    The authors report two cases of primary splenic presentation of malignant lymphoma in Gabon. This disease seems very uncommon but its frequency is perhaps underestimated in Africa. The hypothesis of a possible relation with tropical splenomegaly deserves consideration. At the beginning of the disease large cell types follow a local growing pattern but symptoms are already obvious. Therefore early diagnosis would permit curative splenectomy. PMID:1943638

    Abstract The mutational profiles of primary colorectal cancers (CRCs) and corresponding ovarian metastases were compared. Using a custom‐made next generation sequencing panel, 115 cancer‐driving genes were analyzed in a cohort of 26 primary CRCs and 30 matching ovarian metastases (four with bilateral metastases). To obtain a complete overview of the mutational profile, low thresholds were used in bioinformatics analysis to prevent low frequency passenger mutations from being filtered out. A subset of variants was validated using Sanger and/or hydrolysis probe assays. The mutational landscape of CRC that metastasized to the ovary was not strikingly different from CRC in consecutive series. When comparing primary CRCs and their matching ovarian metastases, there was considerable overlap in the mutations of early affected genes. A subset of mutations demonstrated less overlap, presumably being passenger mutations. In particular, primary CRCs showed a substantially high number of passenger mutations. We also compared the primary CRCs and matching metastases for stratifying variants of six genes (KRAS, NRAS, BRAF, FBXW7, PTEN and PIK3CA) that select for established (EGFR directed) or future targeted therapies. In a total of 31 variants 12 were not found in either of the two locations. Tumours thus differed in the number of discordant variants between the primary tumours and matching metastases. Half of these discordant variants were definitive class 4/5 pathogenic variants. However, in terms of temporal heterogeneity, no clear relationship was observed between the number of discordant variants and the time interval between primary CRCs and the detection of ovarian metastases. This suggests that dormant metastases may be present from the early days of the primary tumours. PMID:27499925

    Twelve patients with suspected primary and recurrent carcinoma of the ovary have undergone immunoscintigraphy with an antitumour monoclonal antibody in order to assess the impact of the technique on patient management. Consistent tumour uptake of radiolabelled antibody was visualized in malignant tumours after subtraction of the blood background activity. Eight patients were imaged before surgery and in all of these the sites of uptake visualized on the images agreed with the surgical findings. In one patient with recurrent disease the imaging information was used as an aid for establishing the extent of external beam radiotherapy. A repeat study in this patient 6 months later revealed a reduction in the size of the tumour, which still concentrated labelled antibody and confirmed the viability of repeat investigations. Immunoscintigraphy was capable of providing diagnostic information which may offer an alternative to second-look surgery in these patients. PMID:3978057

    Purpose The study assessed the outcomes of patients at a single institution with locally advanced primary and recurrent pelvic malignancies treated with interstitial high-dose-rate (HDR) or low-dose-rate (LDR) brachytherapy (BT), using a modified Syed-Neblett template. Material and methods Between 1996 and 2010, 60 patients with primary or recurrent pelvic malignancies were treated with interstitial BT. Thirty three patients had primary malignancies with 6.1% being stage I, 33.3% stage II, 45.5% stage III, and 15.2% stage IV; the remaining 27 patients were recurrent malignancies. Fifty four patients received external beam radiotherapy (EBRT) as part of their treatment course. The median EBRT, BT, and EBRT + BT doses were 45 Gy, 20 Gy, and 65 Gy, respectively. Thirty eight patients received concurrent chemotherapy with EBRT. Complete response (CR) was defined by absence of clinical and radiographic disease on first follow-up. Toxicity was graded as per Common Terminology Criteria for Adverse Events, version 4.0. Results The median follow-up was 37 months (4-234 months) and initial CR was achieved in 91%. For primary cancers at diagnosis, 5-year local control (LC), 5-year progression-free survival (PFS), 5-year overall survival (OS) were 65%, 64%, and 42% respectively. For recurrent cancers at diagnosis, 5-year LC, 5-year PFS, and 5-year OS were 80%, 51%, and 37%, respectively. There was a significant difference in both OS and PFS among different tumor sites (p < 0.05), with vaginal cancers having the best 5-year OS (55%) and PFS (84%). There was a total of 1 acute toxicity ≥ grade 3, 6 late grade 3 toxicities, and late grade 4 toxicity. Conclusions Our series suggests that interstitial BT using a modified Syed-Neblett template is a safe and effective treatment for primary or recurrent pelvic malignancies. This technique allowed effective LC and 97% of patients had preservation of both bladder and rectal function. PMID:27504125

    Background The most common type of ovarian germ cell tumor is the teratoma. Thyroid tissue, both benign and malignant, may be a component of an ovarian teratoma. Here we review this topic and illustrate major features by presenting multimodal management of a patient with BRAF-positive disseminated follicular thyroid cancer arising in an ovarian teratoma. Summary Malignant thyroid tissue is often difficult to distinguish from benign thyroid tissue arising in ovarian teratomas. Preoperatively, an elevated thyroglobulin (Tg) level, laboratory or clinical evidence of hyperthyroidism, or ultrasonography appearance of “struma pearl” should prompt referral to oncologist for surgical management of a possibly malignant ovarian teratoma. Postoperatively, tumor tissue should be referred to pathologists experienced with differentiating benign from malignant struma ovarii. Once diagnosed, treatment of this rare condition should be handled by a team of specialists with combined treatment modalities. We cared for woman with disseminated thyroid cancer arising in an ovarian teratoma whose history illustrates the complexity of managing ovarian teratomas with malignant thyroid tissue. At age 33 she had an intraoperative rupture of an ovarian cyst, thought to be struma ovarii. During her next pregnancy, pelvic masses were noted; biopsies revealed well-differentiated papillary thyroid carcinoma, follicular variant. She was euthyroid, but had elevated serum Tg levels. Surgical staging demonstrated widely metastatic intraabdominal dissemination. A thyroidectomy revealed no malignancy. A post-131I treatment scan revealed diffuse uptake throughout the abdomen. She then developed abdominal pain and, on computed tomography, was found to have multiple intraabdominal foci of disease. Serum Tg was 264 ng/mL while on L-thyroxine for hypothyroidism and to obtain thyrotropin suppression. A 18 fluorodeoxyglucose positron emission tomography scan showed no pathological uptake. The tumor was

    Extrapleural solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm, presenting most commonly in the intrathoracic sites but which has been reported at numerous extrathoracic locations. The majority of intra-thoracic SFTs are benign, but 10%-15% behave aggressively. We report a case of primary hepatic SFT with histologically benign and malignant areas. A 65-year-old man underwent an abdominal CT scan following a cerebrovascular accident, which demonstrated a sharply demarcated large liver mass with a heterogenous enhancing area and occupying most of the left lobe of the liver. Histological examination following a hemihepatectomy showed an SFT with morphological patterns ranging from benign to malignant areas, including pleomorphism, increased cellularity, herringbone pattern, necrosis and a raised mitotic count. On review of the literature, only an occasional case report with malignant areas in a hepatic SFT was identified. This case highlights that SFT should be included in the differential diagnosis of a hepatic spindle cell lesion, and that on rare occasions, malignant areas can occur in this already uncommon neoplasm.

    The classification of extraovarian disease into invasive and noninvasive implants predicts patient outcome in patients with high-stage ovarian serous borderline tumors (tumors of low malignant potential). However, the morphologic criteria used to classify implants vary between studies. To date, there has been no large-scale study with follow-up data comparing the prognostic significance of competing criteria. Peritoneal and/or lymph node implants from 181 patients with high-stage serous borderline tumors were evaluated independently by 3 pathologists for the following 8 morphologic features: micropapillary architecture; glandular architecture; nests of epithelial cells with surrounding retraction artifact set in densely fibrotic stroma; low-power destructive tissue invasion; single eosinophilic epithelial cells within desmoplastic stroma; mitotic activity; nuclear pleomorphism; and nucleoli. Follow-up of 156 (86%) patients ranged from 11 to 264 months (mean, 89 mo; median, 94 mo). Implants with low-power destructive invasion into underlying tissue were the best predictor of adverse patient outcome with 69% overall and 59% disease-free survival (P<0.01). In the evaluation of individual morphologic features, the low-power destructive tissue invasion criterion also had excellent reproducibility between observers (κ=0.84). Extraovarian implants with micropapillary architecture or solid nests with clefts were often associated with tissue invasion but did not add significant prognostic value beyond destructive tissue invasion alone. Implants without attached normal tissue were not associated with adverse outcome and appear to be noninvasive. Because the presence of invasion in an extraovarian implant is associated with an overall survival analogous to that of low-grade serous carcinoma, the designation low-grade serous carcinoma is recommended. Even though the low-power destructive tissue invasion criterion has excellent interobserver reproducibility, it is further

    Primary ovarian insufficiency (POI) is a distressing cause of infertility in young women. POI is heterogeneous with only a few causative genes having been discovered so far. Our objective was to determine the genetic cause of POI in a consanguineous Lebanese family with two affected sisters presenting with primary amenorrhoea and an absence of any pubertal development. Multipoint parametric linkage analysis was performed. Whole-exome sequencing was done on the proband. Linkage analysis identified a locus on chromosome 7 where exome sequencing successfully identified a homozygous two base pair duplication (c.1947_48dupCT), leading to a truncated protein p.(Y650Sfs*22) in the STAG3 gene, confirming it as the cause of POI in this family. Exome sequencing combined with linkage analyses offers a powerful tool to efficiently find novel genetic causes of rare, heterogeneous disorders, even in small single families. This is only the second report of a STAG3 variant; the first STAG3 variant was recently described in a phenotypically similar family with extreme POI. Identification of an additional family highlights the importance of STAG3 in POI pathogenesis and suggests it should be evaluated in families affected with POI. PMID:26059840

Based on this limited number of studies, cutaneous metastases from gynecological malignancies are uncommon occurrences. Cutaneous metastases from the synchronous endometrioid carcinoma of the uterine corpus and bilateral ovaries arising from endometriosis are extremely rare. Herein, we report a 51-year-old woman with FIGO Stage 1A Grade 1 endometrial endometrioid-type adenocarcinoma and synchronous bilateral Stage 1B ovarian endometrioid-type adenocarcinoma who presented 34 months following total abdominal hysterectomy and bilateral salpingo-oophorectomy with skin metastases. After the patient underwent an excisional biopsy, we applied a palliative radiotherapy. The patient received the combination therapy with cisplatin and doxorubicin after the completion of radiotherapy but the disease evolution was rapidly fatal and the patient died 4 months after her admission to our department due to widely disseminated disease.

    Purpose: The aim of our study was to investigate the rate of secondary carcinomas in patients with endometrial carcinoma (EC). In particular, we wanted to describe the subset of patients with endometrial and simultaneous ovarian carcinoma (OC), including outcomes. The study also compared patients with EC and ovarian metastasis with patients with EC and simultaneous OC. Patients and Methods: Data from 251 patients with primary endometrial carcinoma who underwent surgery in the years 2005–2009 at the Department of Obstetrics and Gynaecology, University of Tübingen, were analysed retrospectively. Results: A total of 28 patients (11.1 %) had a secondary carcinoma: 18 patients (7.1 %) had OC; 9 (3.5 %) patients had a history of breast cancer, and one patient (0.4 %) respectively had simultaneous carcinoma of the vulva or bladder. 14 patients (5.5 %) had advanced stage EC with ovarian metastasis or, in one case, metastasis to the ovarian tube. Patients with ovarian metastasis had a mean age of 71.2 ± 9.2 years at primary diagnosis, making them significantly older compared to patients with EC and simultaneous OC (55.3 ± 11.8 years, p < 0.001). Moreover, patients with ovarian metastasis significantly more often had EC with a higher tumour grade (grade 1: 0, grade 2: 21.4 %, grade 3: 78.6 %) compared to patients with simultaneous EC and OC (grade 1: 11.1 %, grade 2: 77.8 %, grade 3: 11.1 %; p < 0.001). Conclusion: Almost one in 10 patients with EC had a secondary carcinoma. The most common secondary carcinoma was OC followed by breast cancer. This should be taken into account in the diagnosis and therapy of patients with EC. Patients with simultaneous EC and OC were significantly younger than patients with EC and ovarian metastasis. In addition, their tumour had better prognostic features: thus, the tumour grade of the EC was significantly lower. Overall, the prognosis for patients with synchronous EC and OC is better than that for

    Primary malignant melanoma of the esophagus (PMME) is a rare malignant neoplasm of the esophagus. In the majority of cases, the disease originates in the mucosal layer of the esophagus, which is similar to other types of esophageal cancer. With the development of endoscopic submucosal dissection (ESD), endoscopic resection is possible for cases in which melanomas are limited to the mucosal and submucosal layer. However, few studies report the efficiency of ESD for PMME, and no studies perform long-term follow-up. The present study reported the case of a 71-year-old PMME patient who was successfully treated by ESD at The Third Affiliated Hospital of Soochow University (Changzhou, China) in Otober 2011, with a follow-up of >3 years conducted.

    Mucins are heavily glycosylated proteins overexpressed and associated with truncated or sialylated glycans upon malignant transformation. We previously identified a panel of four glyco-mucin profiles (MUC16/Tn, MUC16/STn, MUC1/Tn, and MUC1/STn) with 100 % specificity and 100 % positive predictive value for detection of borderline/malignant serous tumors of the ovary, using proximity ligation assay (PLA). In the present work, using the same method, we studied other mucin glycosylation profiles that might add relevant information for diagnostic purposes. We used PLA probes to MUC16, MUC1, sialyl Lewis(a) (SLe(a)), and sialyl Lewis(x) (SLe(x)) to study a series of 39 ovarian serous tumors (14 adenocarcinomas, 10 borderline ovarian tumors (BOTs), and 15 cystadenomas). Our results demonstrated that, in adenocarcinomas and BOTs, the major carriers of SLe(a) and SLe(x) are MUC16 and/or MUC1 (100 and 92 % for SLe(a) and 64 and 70 % for SLe(x), respectively). In cystadenomas, SLe(a) and SLe(x) are mainly carried by unidentified proteins (85 and 78 %, respectively). Our study identified, for the first time, the major protein carriers of SLe(a) and SLe(x) in ovarian adenocarcinomas and BOTs, MUC1 and MUC16, and also that distinct unidentified carriers are involved in cystadenomas. These results emphasize the relevance of multiple biomarker recognition provided by multiplex assays, such as PLA, to enhance sensitivity and specificity of serum and tissue assays. PMID:27003157

    Purpose To identify proteins and (molecular/biological) pathways associated with differences between benign and malignant epithelial ovarian tumors. Experimental Procedures Serum of six patients with a serous adenocarcinoma of the ovary was collected before treatment, with a control group consisting of six matched patients with a serous cystadenoma. In addition to the serum, homogeneous regions of cells exhibiting uniform histology were isolated from benign and cancerous tissue by laser microdissection. We subsequently employed label-free liquid chromatography tandem mass spectrometry (LC-MSe) to identify proteins in these serum and tissues samples. Analyses of differential expression between samples were performed using Bioconductor packages and in-house scripts in the statistical software package R. Hierarchical clustering and pathway enrichment analyses were performed, as well as network enrichment and interactome analysis using MetaCore. Results In total, we identified 20 and 71 proteins that were significantly differentially expressed between benign and malignant serum and tissue samples, respectively. The differentially expressed protein sets in serum and tissue largely differed with only 2 proteins in common. MetaCore network analysis, however inferred GCR-alpha and Sp1 as common transcriptional regulators. Interactome analysis highlighted 14-3-3 zeta/delta, 14-3-3 beta/alpha, Alpha-actinin 4, HSP60, and PCBP1 as critical proteins in the tumor proteome signature based on their relative overconnectivity. The data have been deposited to the ProteomeXchange with identifier PXD001084. Discussion Our analysis identified proteins with both novel and previously known associations to ovarian cancer biology. Despite the small overlap between differentially expressed protein sets in serum and tissue, APOA1 and Serotransferrin were significantly lower expressed in both serum and cancer tissue samples, suggesting a tissue-derived effect in serum.

    Primary cardiac sarcomas are rare. In such tumors, surgical resection is sometimes considered necessary to correct obstruction of flow caused by the tumor and to accomplish complete resection. The anatomic difficulties associated with large, primary, intracavitary left-sided sarcomas have led us to use cardiac explantation, ex vivo tumor resection, and cardiac autotransplantation to meet the anatomic challenges of left atrial tumors. We report the case of a patient who had a large, primary, intracavitary, left ventricular sarcoma that was successfully removed by cardiac explantation and ex vivo reconstruction with use of the cardiac autotransplantation technique. This is the 1st report describing the use of cardiac autotransplantation to surgically resect an intracavitary left ventricular malignancy. PMID:17215979

    Compared with transplanted tumor models or genetically engineered cancer models, chemically induced primary malignancies in experimental animals can mimic the clinical cancer progress from the early stage on. Cancer caused by chemical carcinogens generally develops through three phases namely initiation, promotion and progression. Based on different mechanisms, chemical carcinogens can be divided into genotoxic and non-genotoxic ones, or complete and incomplete ones, usually with an organ-specific property. Chemical carcinogens can be classified upon their origins such as environmental pollutants, cooked meat derived carcinogens, N-nitroso compounds, food additives, antineoplastic agents, naturally occurring substances and synthetic carcinogens, etc. Carcinogen-induced models of primary cancers can be used to evaluate the diagnostic/therapeutic effects of candidate drugs, investigate the biological influential factors, explore preventive measures for carcinogenicity, and better understand molecular mechanisms involved in tumor initiation, promotion and progression. Among commonly adopted cancer models, chemically induced primary malignancies in mammals have several advantages including the easy procedures, fruitful tumor generation and high analogy to clinical human primary cancers. However, in addition to the time-consuming process, the major drawback of chemical carcinogenesis for translational research is the difficulty in noninvasive tumor burden assessment in small animals. Like human cancers, tumors occur unpredictably also among animals in terms of timing, location and the number of lesions. Thanks to the availability of magnetic resonance imaging (MRI) with various advantages such as ionizing-free scanning, superb soft tissue contrast, multi-parametric information, and utility of diverse contrast agents, now a workable solution to this bottleneck problem is to apply MRI for noninvasive detection, diagnosis and therapeutic monitoring on those otherwise

    Primary omental leiomyosarcoma is a rare tumor. We report a case of successfully resected omental leiomyosarcoma whose presentation mimicked ovarian carcinoma. Symptoms of abdominal distension and discomfort that lasted 8 months followed by pain lead to a diagnosis of a large mass in the abdomen. Physical examination revealed a large, over 20 cm tumor, suspected to be of ovarian origin. A small amount of ascites was found on Computerized Tomography (CT) and ultrasound (US) scans. Total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy and tumor debulking procedure was planned. Laparotomy revealed normal uterus ovaries and tubes with a leiomyosarcoma of the omentum which was completely resected successfully. Only 26 cases of primary leiomyosarcoma of the omentum were previously described in the literature. A review of the literature is also presented. PMID:27489871

    A retrospective analysis was performed of 18 patients with primary malignant germ cell tumours of the mediastinum treated with platinum-based chemotherapy between 1977 and 1990. All seven patients with pure seminoma were treated initially with chemotherapy and four of these patients received additional mediastinal radiotherapy. Only one patient relapsed; his initial therapy had included radiotherapy and single-agent carboplatin and he was successfully salvaged with combination chemotherapy. With a follow-up of 11 to 117 months (median 41 months) all seven patients with seminoma remain alive and disease free giving an overall survival of 100%. Eleven patients had malignant non seminoma; following chemotherapy eight of these had elective surgical resection of residual mediastinal masses. Complete remission was achieved in nine (82%) patients, however, one of these patients died from bleomycin pneumonitis. With a follow-up of 12 to 113 months (median 55 months) eight of 11 (73%) patients with malignant mediastinal teratoma remain alive and disease free. PMID:8494705

    Objective. This systematic review aimed to assess current evidence from randomized controlled trials (RCTs) on the effects of acupuncture for patients with primary ovarian insufficiency (POI). Methods. We searched twelve databases to identify relevant studies published before July 2014. The outcomes were serum follicle-stimulating hormone (FSH) levels and resumption of menstruation. Two reviewers independently assessed the risk of bias using the Cochrane's tool, extracted the results, and evaluated the overall level of the evidence using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. Results. Eight RCTs were selected. Acupuncture significantly lowered serum FSH levels and more women receiving acupuncture reported resumption of menses. However, the results should be interpreted with caution due to a small number of participants, high risk of bias for blinding, and likely publication bias. The level of evidence for FSH level and resumption of menses were assessed as “low” using GRADE. Conclusion. The current evidence on acupuncture for POI is insufficient to draw a firm conclusion due to scarcity of studies with a low risk of bias and likely publication bias. Further rigorously designed and conducted studies are needed to confirm the effectiveness and safety of acupuncture in patients with POI. PMID:26089949

    Epithelial ovarian cancer comprises ∼85% of all ovarian cancer cases. Despite acceptance regarding the influence of reproductive hormones on ovarian cancer risk and considerable advances in the understanding of epithelial ovarian carcinogenesis on a molecular level, complete understanding of the biologic processes underlying malignant transformation of ovarian surface epithelium is lacking. Various hypotheses have been proposed over the past several decades to explain the etiology of the disease. The role of reproductive hormones in epithelial ovarian carcinogenesis remains a key topic of research. Primary questions in the field of ovarian cancer biology center on its developmental cell of origin, the positive and negative effects of each class of hormones on ovarian cancer initiation and progression, and the role of the immune system in the ovarian cancer microenvironment. The development of the female reproductive tract is dictated by the hormonal milieu during embryogenesis. Intensive research efforts have revealed that ovarian cancer is a heterogenous disease that may develop from multiple extra-ovarian tissues, including both Müllerian (fallopian tubes, endometrium) and non-Müllerian structures (gastrointestinal tissue), contributing to its heterogeneity and distinct histologic subtypes. The mechanism underlying ovarian localization, however, remains unclear. Here, we discuss the role of reproductive hormones in influencing the immune system and tipping the balance against or in favor of developing ovarian cancer. We comment on animal models that are critical for experimentally validating existing hypotheses in key areas of endocrine research and useful for preclinical drug development. Finally, we address emerging therapeutic trends directed against ovarian cancer. PMID:26373571

    Purpose Veliparib, a poly(ADP-ribose) polymerase (PARP) inhibitor, demonstrated clinical activity in combination with oral cyclophosphamide in patients with BRCA-mutant solid tumors in a phase 1 trial. To define the relative contribution of PARP inhibition to the observed clinical activity, we conducted a randomized phase 2 trial to determine the response rate of veliparib in combination with cyclophosphamide compared to cyclophosphamide alone in patients with pretreated BRCA-mutant ovarian cancer or in patients with pretreated primary peritoneal, fallopian tube, or high-grade serous ovarian cancers (HGSOC). Methods Adult patients were randomized to receive cyclophosphamide alone (50 mg orally once daily) or with veliparib (60 mg orally once daily) in 21-day cycles. Crossover to the combination was allowed at disease progression. Results Seventy-five patients were enrolled and 72 were evaluable for response; 38 received cyclophosphamide alone and 37 the combination as their initial treatment regimen. Treatment was well tolerated. One complete response was observed in each arm, with three partial responses (PR) in the combination arm and six PRs in the cyclophosphamide alone arm. Genetic sequence and expression analyses were performed for 211 genes involved in DNA repair; none of the detected genetic alterations were significantly associated with treatment benefit. Conclusion This is the first trial that evaluated single agent, low dose cyclophosphamide in HGSOC, peritoneal, fallopian tube, and BRCA-mutant ovarian cancers. It was well tolerated and clinical activity was observed; the addition of veliparib at 60 mg daily did not improve either the response rate or the median progression free survival. PMID:25589624

    Background: Paracentesis for malignant ascites is usually performed as an in-patient procedure, with a median length of stay (LoS) of 3–5 days, with intermittent clamping of the drain due to a perceived risk of hypotension. In this study, we assessed the safety of free drainage and the feasibility and cost-effectiveness of daycase paracentesis. Method: Ovarian cancer admissions at Hammersmith Hospital between July and October 2009 were audited (Stage 1). A total of 21 patients (Stage 2) subsequently underwent paracentesis with free drainage of ascites without intermittent clamping (October 2010–January 2011). Finally, 13 patients (19 paracenteses, Stage 3), were drained as a daycase (May–December 2011). Results: Of 67 patients (Stage 1), 22% of admissions and 18% of bed-days were for paracentesis, with a median LoS of 4 days. In all, 81% of patients (Stage 2) drained completely without hypotension. Of four patients with hypotension, none was tachycardic or symptomatic. Daycase paracentesis achieved complete ascites drainage without complications, or the need for in-patient admission in 94.7% of cases (Stage 3), and cost £954 compared with £1473 for in-patient drainage. Conclusions: Free drainage of malignant ascites is safe. Daycase paracentesis is feasible, cost-effective and reduces hospital admissions, and potentially represents the standard of care for patients with malignant ascites. PMID:22878372

    Four percent of 2,446 patients with malignant melanoma did not have a known site of primary origin. More than half were admitted with nodal disease only, and were treated with regional node dissections. Thirty-three percent of this group lived five years, and 22 percent lived ten years following treatment. One third were admitted with visceral metastases, many of which were amenable to surgery, and this group experienced a 5 percent five-year survival rate. Cutaneous dissemination carried a lethal prognosis. Recurrences following treatment tended toward the same region of the body as the original metastasis, and 50 percent of these recurrences occurred within six months of therapy. The sex ratio, age incidence, family history, and survival rates in these patients with unknown primary tumors are consistent with an unnoticed cutaneous lesion as the site of origin for the metastatic disease. It must be supposed that this lesion had undergone spontaneous regression. PMID:1156155

    An autopsy case of a 57-year-old man with primary melanoma of the gallbladder is described. The tumour appeared as a polypoid mass, measuring 4 cm in diameter. Microscopic examination revealed mostly spindle cells with vesicular nuclei and large nucleoli. Many cells stained positively for S 100 protein and HMB 45 using immunohistochemistry and they contained dark brown pigment that stained as melanin pigment with Fontana-Masson. The tumour had metastasised and affected the stomach, the duodenum, the jejunum, the lung, the brain and a bronchopulmonary lymph node. Examination of the skin and both eyes showed no abnormality. Primary malignant melanomas of the gallbladder are very rare. Only 23 cases have been described. These cases are summarized and reviewed. PMID:8130168

    Objective: To study factors possibly associated with tumor contamination in the biopsy path of primary malignant bone tumors. Method: Thirty-five patients who underwent surgical treatment with diagnoses of osteosarcoma, Ewing's tumor and chondrosarcoma were studied retrospectively. The sample was analyzed to characterize the biopsy technique used, histological type of the tumor, neoadjuvant chemotherapy used, local recurrences and tumor contamination in the biopsy path. Results: Among the 35 patients studied, four cases of contamination occurred (11.43%): one from osteosarcoma, two from Ewing's tumor and one from chondrosarcoma. There was no association between the type of tumor and presence of tumor contamination in the biopsy path (p = 0.65). There was also no association between the presence of tumor contamination and the biopsy technique (p = 0.06). On the other hand, there were associations between the presence of tumor contamination and local recurrence (p = 0.01) and between tumor contamination and absence of neoadjuvant chemotherapy (p = 0.02). Conclusion: Tumor contamination in the biopsy path of primary malignant bone tumors was associated with local recurrence. On the other hand, the histological type of the tumor and the type of biopsy did not have an influence on tumor contamination. Neoadjuvant chemotherapy had a protective effect against this complication. Despite these findings, tumor contamination is a complication that should always be taken into consideration, and removal of the biopsy path is recommended in tumor resection surgery. PMID:27047877

    Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age. Insulin resistance/hyperinsulinemia is a prevalent finding in women with PCOS, which indicates that insulin resistance/hyperinsulinemia may be an important player in the pathogenesis of the PCOS. However, the underlying mechanism of insulin resistance/hyperinsulinemia on the pathogenesis of the PCOS remains elusive. In this study, we found an increased high-mobility group box 1 (HMGB1) in the serum from women with PCOS having insulin resistance/hyperinsulinemia. Furthermore, we discovered that high concentration of insulin, which mimics insulin resistance model, promoted apoptosis in primary cultured rat ovarian granulosa cells (GCs) via its effect on the increase in extracellular HMGB1. Our data presented the first evidence that increased HMGB1 induced by insulin resistance/hyperinsulinemia promoted apoptosis of ovarian GCs, which provided new molecular basis for the PCOS pathogenesis.

    Objective To determine the effect of excisional tubal sterilization on subsequent development of serous epithelial ovarian cancer (EOC) or primary peritoneal cancer (PPC). Methods We performed a population-based, nested case-control study using the Rochester Epidemiology Project. We identified all patients with a diagnosis of serous EOC or PPC from 1966 through 2009. Each case was age-matched to 2 controls without either diagnosis. Odds ratios (ORs) and corresponding 95% CIs were estimated from conditional logistic regression models. Models were adjusted for prior hysterectomy, prior salpingo-oophorectomy, oral contraceptive use, endometriosis, infertility, gravidity, and parity. Results In total, we identified 194 cases of serous EOC and PPC during the study period and matched them with 388 controls (mean [SD] age, 61.4 [15.2] years). Fourteen cases (7.2%) and 46 controls (11.9%) had undergone tubal sterilization. Adjusted risk of serous EOC or PPC was slightly lower after any tubal sterilization (OR, 0.59 [95% CI, 0.29–1.17]; P=.13). The rate of excisional tubal sterilization was lower in cases than controls (2.6% vs 6.4%). Adjusted risk of serous EOC and PPC was decreased by 64% after excisional tubal sterilization (OR, 0.36 [95% CI, 0.13–1.02]; P=.054) compared with those without sterilization or with nonexcisional tubal sterilization. Conclusions We present a population-based investigation of the effects of excisional tubal sterilization on the risk of serous EOC and PPC. Excisional methods may confer greater risk reduction than other sterilization methods. PMID:25316178

    Large-scale medical sequencing provides a focal point around which to reorganize health care and health care research. Mobile health (mHealth) is also currently undergoing explosive growth and could be another innovation that will change the face of future health care. We are employing primary ovarian insufficiency (POI) as a model rare condition to explore the intersection of these potentials. As both sequencing capabilities and our ability to intepret this information improve, sequencing for medical purposes will play an increasing role in health care beyond basic research: it will help guide the delivery of care to patients. POI is a serious chronic disorder and syndrome characterized by hypergonadotrophic hypogonadism before the age of 40 years and most commonly presents with amenorrhea. It may have adverse health effects that become fully evident years after the initial diagnosis. The condition is most commonly viewed as one of infertility, however, it may also be associated with adverse long-term outcomes related to inadequate bone mineral density, increased risk of cardiovascular disease, adrenal insufficiency, hypothyroidism and, if pregnancy ensues, having a child with Fragile X Syndrome. There may also be adverse outcomes related to increased rates of anxiety and depression. POI is also a rare disease, and accordingly, presents special challenges. Too often advances in research are not effectively integrated into community care at the point of service for those with rare diseases. There is a need to connect community health providers in real time with investigators who have the requisite knowledge and expertise to help manage the rare disease and to conduct ongoing research. Here we review the pathophysiology and management of POI and propose the development of an international Clinical Research Integration Special Program (CRISP) for the condition. PMID:25288327

    Purpose This study assesses the ability of multidrug resistance (MDR)-associated gene expression patterns to predict survival in patients with newly diagnosed carcinoma of the ovary. The scope of this research differs substantially from that of previous reports, as a very large set of genes was evaluated whose expression has been shown to affect response to chemotherapy. Experimental Design We applied a customized TaqMan Low Density Array, a highly sensitive and specific assay, to study the expression profiles of 380 MDR-linked genes in 80 tumor specimens collected at initial surgery to debulk primary serous carcinoma. The RNA expression profiles of these drug resistance genes were correlated with clinical outcomes. Results Leave-one-out cross-validation was used to estimate the ability of MDR gene expression to predict survival. Although gene expression alone does not predict overall survival (P=0.06), four covariates (age, stage, CA125 level and surgical debulking) do (P=0.03). When gene expression was added to the covariates, we found an 11-gene signature that provides a major improvement in overall survival prediction (log-rank statistic P<0.003). The predictive power of this 11-gene signature was confirmed by dividing high and low risk patient groups, as defined by their clinical covariates, into four specific risk groups based on expression levels. Conclusion This study reveals an 11-gene signature that allows a more precise prognosis for patients with serous cancer of the ovary treated with carboplatin- and paclitaxel-based therapy. These 11 new targets offer opportunities for new therapies to improve clinical outcome in ovarian cancer. PMID:22492981

    Metastases to the breast from tumors other than breast carcinomas are extremely rare and represent only 0.2–1.3% of all diagnosed malignant breast tumors. Furthermore, while the most common sites for advanced ovarian cancer metastases are the liver, lung, and pleura, metastasis to the breast from a primary ovarian cancer is uncommon and has only been reported in 0.03–0.6% of all breast cancers. Here we describe a case report of a 50-year-old female patient with a rare case of breast metastases from an advanced ovarian cancer, presenting as inflammatory breast cancer. Our observations emphasize the clinical importance of distinguishing between primary and metastatic breast cancer during diagnosis for the purpose of appropriate prognosis and treatment.

    Second primary malignancies (SPMs) are issues for patients with multiple myeloma (MM). There may have been some limitations in prior studies, such as difficulties in a longer follow-up and absence of established screening methods. Therefore, we studied autopsied cases to overcome these limitations. This study aimed to examine SPMs using autopsy reports. Ninety-one cases of MM autopsied at our institution from 1979 to 2013 were analyzed. Median age of autopsied patients was 64.1 years, and proportion of male/female was 59/32. Autopsy was performed in 35.3% of patients died of MM. There were five cases of SPMs with a median confirmation time of 38 (12-132) months from the diagnosis of MM. In three of the five patients, the diagnosis of SPMs was established at autopsy. One case was of myelodysplastic syndrome, and the others were of non-hematological malignancies. The annual risk of SPM estimated using the Kaplan-Meier method was approximately 1%. Three of five SPM cases were detected at autopsy. Analysis of autopsy may contribute to estimate the actual risk of SPMs in MM. PMID:26788269

    This second part of a comprehensive review of primary vertebral tumors focuses on locally aggressive and malignant tumors. As discussed in the earlier part of the review, both benign and malignant types of these tumors affect the adult and the pediatric population, and an understanding of their subtleties may increase their effective resection. In this review, we discuss the epidemiologic, histological, and imaging features of the most common locally aggressive primary vertebral tumors (chordoma and giant-cell tumor) and malignant tumors (chondrosarcoma, Ewing sarcoma, multiple myeloma or plasmacytoma, and osteosarcoma). The figures used for illustration are from operative patients of the senior authors (Z.L.G. and J.H.C.).

    Ovarian cancer is a leading gynecological malignancy associated with high mortality. The development of acquired drug resistance is the primary cause of chemotherapy failure in the treatment of ovarian cancer. To examine the mechanism underlying paclitaxel resistance in ovarian cancer and attempt to reverse it, the present study induced a TAX-resistant ovarian cancer cell line, SKOV3/TAX. Cathepsin L (CTSL) has been found to be overexpressed in ovarian cancer. The aim of the present study was to investigate the possible involvement of CTSL in the development of TAX resistance in ovarian cancer. CTSL expression was knocked down in SKOV3 ovarian cancer cells and their phenotypic changes were analyzed. The effects of silenced CTSL on the resistant cell line were investigated by proliferation and apoptosis analysis compared with control SKOV3 cells. CTSL was more highly expressed in SKOV3/TAX cells compared with SKOV3 cells. Paclitaxel treatment downregulated the expression of CTSL in SKOV-3 but not in the paclitaxel-resistant SKOV3/TAX cells. CTSL small hairpin RNA (shRNA) knockdown significantly potentiated apoptosis induced by paclitaxel compared with SKOV3/TAX cells transfected with control shRNA, suggesting that CTSL contributes to paclitaxel resistance in ovarian cancer cells and that CTSL silencing can enhance paclitaxel-mediated cell apoptosis. Thus, CTSL should be explored as a candidate of therapeutic target for modulating paclitaxel sensitivity in ovarian cancer. PMID:27313771

    Objective Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome “resistance” in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. Methods Epirubicin, cisplatin, and capecitabine (ECX) combination chemotherapy was used at our institution for the treatment of relapsed EOC. From the institutional database, we identified all patients with primary platinum-refractory or platinum-resistant relapse treated with ECX as second-line therapy between 2001 and 2012. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used logistic and Cox regression models to identify predictors of response and survival respectively. Results Thirty-four 34 patients (8 refractory, 26 resistant) were treated with ECX. Response Evaluation Criteria In Solid Tumors (RECIST) response rate was 45%, median progression-free survival (PFS) was 6.4 months, and overall survival (OS) was 10.6 months. Platinum-resistant patients had better outcomes than did platinum-refractory patients (response rate, 54% vs 0%, P = 0.047; PFS 7.2 vs 1.8 months, P < 0.0001; OS 14.4 vs 3 months, P < 0.001). In regression models, time to progression after first-line treatment and platinum-refractory status were the strongest predictors of response and PFS or OS, respectively. Patients with time to progression after first-line treatment longer than 3 months showed PFS and OS of 7.9 and 14.7 months, respectively. Toxicity was manageable, with only 13% of cycles administered at reduced doses. Conclusions Epirubicin, cisplatin, and capecitabine seems to be active in platinum-resistant relapsed EOC with manageable toxicity. Further prospective investigation of platinum-anthracycline combinations is warranted in patients who relapse 3 to 6 months after

    The clinical records and histologic sections of 96 cases of primary small bowel malignancies (excluding lymphomas and periamullary lesions) were reviewed. The location, clinical presentation, pathologic findings, treatment and outcome are compared to the collected published experience, approximately 2400 cases. There were 48 adenocarcinomas, 37 carcinoids, and 11 leiomyosarcomas. Fifty-one men and 45 women ranged from 31 to 83 years old. Eighty-four caused symptoms leading to operative diagnosis; 12 carcinoids were incidental autopsy findings. The most common presentation was pain (33%) followed by weight loss (23%) obstruction (16%), hemorrhage (15%), jaundice (5%), intussusception (3%) and perforation (3%). Masses were felt in 30% of the cases, but were usually dilated bowel or intussusception rather than the tumor per se. Curative resection was attempted in 80 of 84 operatively diagnosed tumors. The 80% mortality among patients followed 5 years is attributed to the late appearance of symptoms and anatomic obstacles to a truly radical operation. PMID:4843046

    In this work we present the experimental results indicating that under photodynamic therapy the primary stage of the photodestruction of malignant cells is based on the irreversible photodestruction of glycolysis enzymes located, first of all, in mitochondria playing a key role in the energy supply for the tumor cells. It was shown that the formation of complexes between glycolysis enzymes and a sensitizer promotes an effective destruction of the formers. The formation of strong complexes was demonstrated for a number of glycolysis enzymes (glyceraldehyde-2-phosphate dehydrogenase, pyruvate kinase, lactate dehydrogenase) with the use of water-soluble pigments chlorin e6 and tetra(carboxyphenyl)porphyrin (T(CP)P) as sensitizers. The direct correlation was shown between the effectiveness of the photodestruction of enzyme molecules and the enzyme-sensitizer binding constant.

    Primary renal echinococcosis, a rare disease involving the kidney, accounts for 2-3% of human echinococcosis. A 64-year-old female patient from Uzbekistan presented with complaints of left flank pain. A CT scan revealed a cystic mass in the upper to midpole of the left kidney. We regarded this lesion as a renal malignancy and hand-assisted laparoscopic radical nephrectomy was performed to remove the renal mass. The mass consisted of a large unilocular cyst and multiple smaller cysts without any grossly visible renal tissue. The final pathologic diagnosis was a renal hydatid cyst. For patients from endemic areas, hydatid cyst should be included in the differential diagnosis. Here, we present a case of renal hydatid cyst in a female patient who relocated from Uzbekistan to Korea. PMID:25031471

    Hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) account for 95% of primary liver cancer. For each of these malignancies the outcome is dismal; incidence is rapidly increasing and mechanistic understanding is limited. We observed abnormal proliferation of both biliary epithelium and hepatocytes in mice following genetic manipulation of Yes associated protein (YAP), a transcription co-activator. Here we comprehensively documented YAP protein expression in the human liver and primary liver cancers. We showed that nuclear YAP expression is significantly increased in human ICC and HCC. We found that increased YAP protein levels in HCC are due to multiple mechanisms including gene amplification, transcriptional and posttranscriptional regulation. Survivin, a member of the inhibitors-of-apoptosis protein (IAPs) family, has been reported as an independent prognostic factor for poor survival in both HCC and ICC. We found nuclear YAP expression correlates significantly with nuclear Survivin expression for both ICC and HCC. Furthermore, using mice engineered to conditionally overexpress YAP in the liver, we found Survivin mRNA expression depends upon YAP protein levels. Our findings suggested that YAP contributes to primary liver tumorigenesis and likely mediates its oncogenic effects through modulating Survivin expression. PMID:22436626

    We aimed at investigating risk of specific second primary cancers (SPCs) after malignant mesothelioma (MM) and vice versa, which has not been reported. Among survivors of 3672 pleural MM and 895 peritoneal MM, overall 113 and 28 SPCs were recorded, respectively, while reverse analyses included overall 431 pleural and 88 peritoneal MMs after any first cancers. We found a bidirectional association of pleural MM with kidney cancer for overall [for second kidney cancer after pleural MM: standardized incidence ratios (SIRs) = 4.4, 95% confidence intervals (CIs): 2.0-8.3; for second pleural MM after kidney cancer: 2.3 (1.3-3.9)] and for <1 year follow-up [5.4 (2.0-12) and 4.9 (2.0-10), respectively, according to the 2-way analyses]. In contrast, a bidirectional association of pleural MM with unknown primary cancer was found only for follow-up ≥1 year [3.9 (1.1-10) and 2.8 (1.3-5.1), respectively]. We found a bidirectional association of pleural MM with kidney cancer for overall and for <1 year follow-up, suggesting the involvement of germline BAP1 mutations and increased medical surveillance, while the bidirectional association of pleural MM with unknown primary cancer suggests shared genetic or environmental risk factors.

    Tissue culture has been an invaluable tool to study many aspects of cell function, from normal development to disease. Conventional cell culture methods rely on the ability of cells either to attach to a solid substratum of a tissue culture dish or to grow in suspension in liquid medium. Multiple immortal cell lines have been created and grown using such approaches, however, these methods frequently fail when primary cells need to be grown ex vivo. Such failure has been attributed to the absence of the appropriate extracellular matrix components of the tissue microenvironment from the standard systems where tissue culture plastic is used as a surface for cell growth. Extracellular matrix is an integral component of the tissue microenvironment and its presence is crucial for the maintenance of physiological functions such as cell polarization, survival, and proliferation. Here we present a 3-dimensional tissue culture method where primary bone marrow cells are grown in extracellular matrix formulated to recapitulate the microenvironment of the human bone (rBM system). Embedded in the extracellular matrix, cells are supplied with nutrients through the medium supplemented with human plasma, thus providing a comprehensive system where cell survival and proliferation can be sustained for up to 30 days while maintaining the cellular composition of the primary tissue. Using the rBM system we have successfully grown primary bone marrow cells from normal donors and patients with amyloidosis, and various hematological malignancies. The rBM system allows for direct, in-matrix real time visualization of the cell behavior and evaluation of preclinical efficacy of novel therapeutics. Moreover, cells can be isolated from the rBM and subsequently used for in vivo transplantation, cell sorting, flow cytometry, and nucleic acid and protein analysis. Taken together, the rBM method provides a reliable system for the growth of primary bone marrow cells under physiological conditions

    Serum amyloid A (SAA) is an acute phase protein which is expressed primarily in the liver as a part of the systemic response to various injuries and inflammatory stimuli; its expression in ovarian tumors has not been described. Here, we investigated the expression of SAA in human benign and malignant ovarian epithelial tumors. Non-radioactive in situ hybridization applied on ovarian paraffin tissue sections revealed mostly negative SAA mRNA expression in normal surface epithelium. Expression was increased gradually as epithelial cells progressed through benign and borderline adenomas to primary and metastatic adenocarcinomas. Similar expression pattern of the SAA protein was observed by immunohistochemical staining. RT-PCR analysis confirmed the overexpression of the SAA1 and SAA4 genes in ovarian carcinomas compared with normal ovarian tissues. In addition, strong expression of SAA mRNA and protein was found in the ovarian carcinoma cell line OVCAR-3. Finally, patients with ovarian carcinoma had high SAA serum levels, which strongly correlated with high levels of CA-125 and C-reactive protein. Enhanced expression of SAA in ovarian carcinomas may play a role in ovarian tumorigenesis and may have therapeutic application. PMID:20713982

    Background: Ovarian pregnancy constitutes 0.15-3% of all ectopic pregnancies. The incidence of ectopic pregnancy is on the rise owing to evolution in assisted reproductive techniques (ART). The incidence reported following In vitro fertilization (IVF) or embryo transfer (ET) is 0.27% per clinical pregnancy. Case: We present a case of a 13-weeks ovarian pregnancy following IVF-ET and through a review of the literature, the specific symptomatology, diagnostic criteria, and treatment of this particular pathology will be described. Conclusion: Ovarian pregnancy is a rare condition and its diagnosis is difficult and relies on criteria based on intraoperative and histopathological findings. The management is, in spite of medical improvement, based on surgery. But the trend has shifted towards conservative surgeries in majority of cases. PMID:25709634

    Background With the expanding population of colorectal cancer (CRC) survivors in the United States, one concerning issue is the risk of developing second primary malignancies (SPMs) for these CRC survivors. The present study attempts to identify the incidence characteristics of SPMs after diagnosis of first primary colon cancer (CC) and rectal cancer (RC). Methods 189,890 CC and 83,802 RC cases were identified from Surveillance, Epidemiology and End Results Program (SEER) database. We performed rate analysis on incidence trend of SPMs in both CC and RC. Expected incidence rates were stratified by age, race and stage, calendar year of first CRC diagnosis and latency period since first CRC diagnosis. The standardized incidence ratios (SIRs), measure for estimating risk of SPMs, were calculated for CC and RC respectively. Results The trends of incidence of SPMs in both CC and RC were decreasing from 1992 to 2012. Both CC and RC survivors had higher risk of developing SPMs (SIRCC = 1.13; SIRRC = 1.05). For CC patients, the highest risks of SPM were cancers of small intestine (SIR = 4.03), colon (SIR = 1.87) and rectum (SIR = 1.80). For RC patients, the highest risks of SPMs were cancers of rectum (SIR = 2.88), small intestine (SIR = 2.16) and thyroid (SIR = 1.46). According to stratified analyses, we also identified incidence characteristics which were contributed to higher risk of developing SPMs, including the age between 20 and 40, American Indian/Alaska Native, localized stage, diagnosed at calendar year from 2002 to 2012 and the latency between 12 and 59 months. Conclusions Both CC and RC survivors remain at higher risk of developing SPMs. The identification of incidence characteristics of SPMs is extremely essential for continuous cancer surveillance among CRC survivors.

    Epidemiological data have implicated the pituitary gonadotropin follicle stimulating hormone (FSH) as both a risk factor for and a protective agent against epithelial ovarian cancer. Yet, little is known about how this hormone could play such opposing roles in ovarian carcinogenesis. Complementary DNA microarrays containing 2400 named genes were used to examine FSH-induced gene expression changes in ovarian cancer (OC) and immortalized normal human ovarian surface epithelial (HOSE) cell lines. Two-way t-statistics analyses of array data identified two distinct sets of FSH-regulated genes in HOSE and in established OC cell lines established from patients (OVCA cell lines). Among the HOSE cell lines, FSH increased expression of 57% of the 312 genes and downregulated 43%. In contrast, FSH diminished expression of 92% of the 177 genes in the OVCA cell lines. All but 18 of the genes affected by FSH in HOSE cell lines were different from those altered in OVCA cell lines. Among the 18 overlapping genes, nine genes exhibited the same direction of change following FSH challenge, while the other nine showed discordance in response between HOSE and OVCA cell lines. The FSH-induced differential expression of seven out of nine genes was confirmed by real-time RT-PCR. Gene-specific antisense oligonuleotides (ODNs) were used to inhibit the expression of genes encoding GTPase activating protein (rap1GAP), neogenin, and restin in HOSE and OVCA cells. Antisense ODNs to neogenin and restin, but not an antisense ODN to rap1GAP, were effective in inhibiting OVCA cell growth, diminishing proliferating cell nuclear antigen expression, and increasing caspase 3 activities. Furthermore, the ODN to rap1GAP was further shown to be ineffective in altering migration properties of OVCA cell lines. HOSE cell proliferation was not affected by treatment with any of the antisense ODNs. In summary, gene profiling data reveal for the first time that FSH may exert different biological actions on OVCA

    Why is it that primary melanomas which are less than 0.76 mm in thickness are almost always curable by surgery whereas thicker lesions are associated with a worse prognosis? Put in another way, why is it that such small increases in tumor thickness beyond 0.76 mm are often associated with the eventual formation of distant metastases and death? Part of the answer lies in the dramatic qualitative changes which can accompany small increases in the size of primary human melanomas. Thus, primary melanomas less than 0.76 mm in thickness usually contain very low proportions of metastatically competent tumor cells, whereas slightly thicker lesions can contain very high proportions of such cells, resulting from a selective growth advantage of the latter in the dermal mesenchyme. This overgrowth process is akin to a 'malignant eclipse' phenomenon (by analogy with a solar eclipse). We have been studying the causes of the malignant eclipse in melanoma, for which there are at least four possibilities: 1) an increase in autocrine, mitogenic growth factors by melanoma cells; 2) a decreased rate of apoptosis in the same population; 3) an acquired resistance to paracrine growth inhibitory factors; and 4) an increased ability to induce an angiogenic response. Evidence exists for all four possibilities. Our experimental approach to studying this problem has relied heavily on the use of cell lines obtained from early stage radial growth phase or vertical growth phase lesions which have a clinical-like inability to grow progressively in nude mice, and variants obtained from such lines which are aggressively tumorigenic. Using such paired lines, and other experimental systems, we have obtained evidence that shows early stage melanoma cell lines may be deficient in inducing angiogenesis, are highly sensitive to the growth inhibitory effects of a plethora of cytokines, including transforming growth factor beta, interleukin-6, and oncostatin M, and are more sensitive to undergoing

    A novel form of primary feline hemangiosarcoma and additional cases of plexiform vascularization in the cervical lymph nodes are reported. Sixteen cases of feline lymphadenopathy attributed to abnormal vascular proliferation were identified and evaluated. Most of these lesions were diagnosed histologically as hemangiosarcoma. However, lesions of plexiform vascularization, with and without areas of putative malignant transformation, were also identified. Mean age of the cats was 11 years (range, 3-16 years) with most being domestic shorthair and medium hair (13). Two domestic long hair and 1 Maine Coon were identified. Excisional nodal biopsy was performed in 15 cases and incisional biopsy in 1 case. Six cats were euthanized due to their disease. Survival times ranged from ≤ 1 month to ≥ 30 months. We provide a new clinical differential for cervical lymphadenopathy in cats that is not widely recognized. Proper identification of primary nodal vascular lesions in cats will enable further characterization of clinical features and biologic behavior to determine specific therapy. PMID:24879661

    Objectives Simultaneous second primary tumors (SSPT) are not uncommon in patients with oral cavity squamous cell carcinoma (OSCC) living in areas where the habit of betel quid chewing is widespread. We sought to identify the main prognostic factors in OSCC patients with SSPT and incorporate them into a risk stratification scheme. Methods A total of 1822 consecutive patients with primary OSCC treated between January 1996 and February 2014 were analyzed for the presence of SSPT. The 18-month and 5-year overall survival (OS) rates served as the main outcome measures. Results Of the 1822 patients, 77 (4%) were found to have SSPT (i.e, two malignancies identified within one month of each other). The 18-month and 5-year OS rates in patients without SSPT and with SSPT were 82% and 69%, and 72% and 53%, respectively (p = 0.0063). Patients with SSPT were further divided into patients with either esophageal cancer or hepatocellular carcinoma (eso-HCC subgroup, n = 8) and other tumors (NO eso-HCC subgroup, n = 69). After multivariate analysis, neck nodal extracapsular spread (ECS, n = 18) and the presence of eso-HCC were identified as independent adverse prognostic factors. The 18-month OS rates of SSPT patients with both eso-HCC and ECS (n = 5) vs. the remaining patients (n = 72) were 0% and 78%, respectively (p < 0.0001). Conclusion OSCC patients with neck nodal ECS and esophageal cancer or hepatocellular carcinoma as SSPT have a dismal short-term prognosis. PMID:26335067

    Primary malignant melanoma of the esophagus (PMME) is an extremely rare disease with poor prognosis. We summarized and analyzed the characteristics of 17 PMME patients (with average age of 57.5 ± 10.3 years) who had received surgical resection in our center. The majority (13/17, 76.5%) of the patients were male. The percentage of patients with smoking and alcohol consumption was 41.2% and 23.5%, respectively. The preoperative diagnosis rate was 35.3%. Lymph node metastasis mainly involved the mid-lower mediastinal and upper abdominal area. Primary tumors that invaded beyond the submucosa layer (T2–T4) had much higher tendency of lymph node metastasis than those restricted to the submucosa layer (T1) (6/8, 75.0% vs. 3/9, 33.3%, p = 0.086). The 1-year and 5-year survival rate of the patients was 51% and 10%, respectively, with median survival time being 18.1 months. Survival analysis showed that TNM stage was a predictor for PMME prognosis (median survival time of 47.3 months vs. 8.0 months for stage I/II vs. stage III, respectively, p = 0.018), and multivariable Cox regression analysis revealed the independence of its prognostic value [HR (95% CI): 5.678 (1.125–28.658), p = 0.035].

    We investigated the levels of TGF-beta in malignant pleural effusions (MPE) caused by malignant mesothelioma (MESO) or primary lung cancer. TGF-beta levels in MPE caused by MESO were 283.9 +/- 219.2 pm (mean +/- s.d.) and were three to six times higher than those due to primary lung cancers (P < 0.01 or P < 0.05). We also evaluated TGF-beta 1- and beta 2-like activities in MPE using specific polyclonal antibodies. Although TGF-beta 1-like activity could be detected in all cases, TGF-beta 2-like activities were detected in five of seven in MESO and in a few cases with primary lung cancer. These results demonstrate that the levels of total TGF-beta and TGF-beta 2-like activity may be clinically useful to differentiate MESO from primary lung cancer. Our data also suggest that TGF-beta may help further characterize the clinical features of MESO. PMID:7955539

    Currently, 17–19% of all new primary malignancies occur in survivors of cancer, causing substantial morbidity and mortality. Research has shown that cancer treatments are important contributors to second malignant neoplasm (SMN) risk. In this paper we summarise current knowledge with regard to treatment-related SMNs and provide recommendations for future research. We address the risks associated with radiotherapy and systemic treatments, modifying factors of treatment-related risks (genetic susceptibility, lifestyle) and the potential benefits of screening and interventions. Research priorities were identified during a workshop at the 2014 Cancer Survivorship Summit organised by the European Organisation for Research and Treatment of Cancer. Recently, both systemic cancer treatments and radiotherapy approaches have evolved rapidly, with the carcinogenic potential of new treatments being unknown. Also, little knowledge is available about modifying factors of treatment-associated risk, such as genetic variants and lifestyle. Therefore, large prospective studies with biobanking, high quality treatment data (radiation dose–volume, cumulative drug doses), and data on other cancer risk factors are needed. International collaboration will be essential to have adequate statistical power for such investigations. While screening for SMNs is included in several follow-up guidelines for cancer survivors, its effectiveness in this special population has not been demonstrated. Research into the pathogenesis, tumour characteristics and survival of SMNs is essential, as well as the development of interventions to reduce SMN-related morbidity and mortality. Prediction models for SMN risk are needed to inform initial treatment decisions, balancing chances of cure and SMNs and to identify high-risk subgroups of survivors eligible for screening.

    Bone Morphogenetic Protein 15 (BMP15) is a TGFβ-like oocyte-derived growth factor involved in ovarian folliculogenesis as a critical regulator of many granulosa cell processes. Alterations of the BMP15 gene have been found associated with different ovarian phenotypic effects depending on the species, from sterility to increased prolificacy in sheep, slight subfertility in mouse or associated with primary ovarian insufficiency (POI) in women. To investigate the evolving role of BMP15, a phylogenetic analysis of this particular TGFβ family member was performed. A maximum likelihood phylogenetic tree of several TGFβ/BMP family members expressed by the ovary showed that BMP15 has a very strong divergence and a rapid evolution compared to others. Moreover, among 24 mammalian species, we detected signals of positive selection in the hominidae clade corresponding to F146, L189 and Y235 residues in human BMP15. The biological importance of these residues was tested functionally after site directed-mutagenesis in a COV434 cells luciferase assay. By replacing the positively selected amino acid either by alanine or the most represented residue in other studied species, only L189A, Y235A and Y235C mutants showed a significant increase of BMP15 signaling when compared to wild type. Additionally, the Y235C mutant was more potent than wild type in inhibiting progesterone secretion of ovine granulosa cells in primary culture. Interestingly, the Y235C mutation was previously identified in association with POI in women. In conclusion, this study evidences that the BMP15 gene has evolved faster than other members of the TGFß family and was submitted to a positive selection pressure in the hominidae clade. Some residues under positive selection are of great importance for the normal function of the protein and thus for female fertility. Y235 represents a critical residue in the determination of BMP15 biological activity, thus indirectly confirming its role in the onset of POI in

    Identification of prognostic melanoma-associated copy number alterations (CNAs) is still an area of active research. Here, we investigated by high-resolution array comparative genomic hybridization (aCGH) a cohort of 31 paraffin-preserved primary malignant melanomas (MMs), whose prognosis was not predictable on the basis of conventional histopathological parameters. Although we identified a variety of highly recurrent sites of genomic lesions, the total number of CNAs per patient was not a discriminator of MM outcome. Furthermore, validation of aCGH by quantitative PCR on an extended population of 65 MM samples confirmed the absence of predictive value for the most recurrent CNA loci. Instead, our analysis revealed specific prognostic potential of the frequency of homozygous deletions (representing less than 3% of the total CNAs on average per sample), which was strongly associated with sentinel lymph node (SLN) invasion (P = 0.003), and distant metastasis (P = 0.003). Increased number of homozygous deletions was also indicative of poor patient survival (P = 0.01), both in our samples and in an independent validation of public dataset of primary and metastatic MMs. Moreover, we identified 77 hotspots of minimal common homozygous deletions, enriched in genes involved in cell adhesion processes and cell-communication functions, which preferentially accumulated in primary MMs showing the most severe outcome. Therefore, specific loss of gene loci in regions of minimal homozygous deletion may represent a pivotal type of genomic alteration accumulating during MM progression with potential prognostic implication.

    This study evaluated the effects of kit ligand (KL) on the morphology and development of ovine preantral follicles (fresh control) and after 7 days of in vitro culture in α-Minimal Essential Medium (α-MEM; control medium) or the presence of KL (1, 10, 50, 100 or 200 ng/ml). There was an increase in the percentage of primary follicles at the concentration of 100 ng/ml KL, compared with the fresh control, control medium (α-MEM) and the other KL concentrations. Follicle diameter was significantly higher than the control medium only at concentrations of 50 and 100 ng/ml KL. In conclusion, 100 ng/ml KL promoted the transition from primordial to primary follicles (follicular activation) after in vitro culture of ovine ovarian tissue. PMID:26503557

    Background Ovarian cancer is the sixth most common cancer and seventh cause of cancer death in women worldwide. Traditionally, many patients who have been treated for cancer undergo long-term follow up in secondary care. Recently however it has been suggested that the use of routine review may not be effective in improving survival, quality of life (QoL), and relieving anxiety. In addition, it may not be cost effective. Objectives To compare the potential benefits of different strategies of follow up in women with epithelial ovarian cancer following completion of primary treatment. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2010, Issue 4), MEDLINE and EMBASE (to November 2010). We also searched CINAHL, PsycLIT, registers of clinical trials, abstracts of scientific meetings, reference lists of review articles, and contacted experts in the field. Selection criteria All relevant randomised controlled trials (RCTs) that evaluated follow-up strategies for patients with epithelial ovarian cancer following completion of primary treatment. Data collection and analysis Two review authors independently abstracted data and assessed risk of bias. Main results We found only one RCT (Rustin 2010) that met our inclusion criteria. This trial included 529 women and reported data on immediate treatment versus delayed treatment in women with confirmation of remission and with normal CA125 concentration and no radiological evidence of disease after surgery and first-line chemotherapy. Overall survival showed no significant difference between the immediate and delayed arms after a median follow up of 56.9 months (unadjusted hazard ratio (HR) = 0·98, 95% confidence interval (CI) 0·80 to 1·20; P = 0·85). Time from randomisation to first deterioration in global health score or death was significantly shorter in the early group compared with the delayed group (HR 0

    Second primary malignancy (SPM) is the major long-term cause of patient mortality with head and neck squamous cell carcinoma (HNSCC). As the incidence of high-risk human papillomavirus (HPV)-related HNSCC is increasing globally, we analyzed the patterns of SPM occurrence, the effect of the index tumor site along with attributes to HPV, and the effect of SPM on survival in South Korean patients with head and neck cancer (HNC). Data were retrieved from the Korea Central Cancer Registry, a nationwide population-based cancer registry, from 1993 to 2010. Standardized incidence ratios were analyzed and compared between index tumor sites, particularly oropharyngeal vs. non-oropharyngeal sites. After adjustment for competing risks, 3- and 5-year SPM rates were calculated using the cumulative incidence function. The effects of SPM occurrence on overall survival (OS) were then analyzed. SPM rates were significantly lower for HPV-attributable oropharyngeal sites than for non-oropharyngeal sites, such as the larynx and hypopharynx (p<0.001). SPM rates were also lower for oral cavity first primary sites than for non-oropharyngeal first primary sites (p<0.001). SPMs typically occurred in the esophagus, lungs and the head and neck. Uterine cervical cancers occurred significantly more frequently after index oropharyngeal cancer in women. The 5-year and 10-year OS rates were 57.8 and 45.7% in all HNC patients, respectively. The OS after SPM occurrence was poor (5-year, 31.8%; 10-year, 20.8%) compared to after index HNC occurrence (5-year, 68.4%; 10-year, 41.2%). SPM occurrence in the esophagus and lung/bronchus showed a worse OS than SPM localized to the head and neck. South Korean HNC patient, the first primary cancer site affected SPM risk and distribution. The 5- and 10-year OS rates deteriorated after SPM occurrence, particularly in the esophagus and lungs.

    Primary anorectal (PA) malignant melanoma (MM) is a rare disease associated with a high mortality rate. The most appropriate treatment strategy for PAMM remains controversial. A 55-year-old female patient, who was misdiagnosed with locally advanced rectal carcinoma, was treated with preoperative radiotherapy and concurrent oral capecitabine. During the therapy, grade 1 leukopenia occurred, however, there was no interruption to treatment. Following chemoradiotherapy, a computer tomography scan identified that the tumor had shrunk significantly and the original enlarged lymph nodes had disappeared. Eight weeks after completion of chemoradiotherapy, sphincter-sparing surgery was performed on the patient and based on the postoperative pathological result, MM was diagnosed. At the time of writing, the patient has survived disease-free for 15 months and at the most recent follow-up examination the Karnofsky Performance Scale score was 100. The therapeutic regimen of neoadjuvant concurrent chemoradiotherapy together with sphincter-sparing surgery is considered to be an optimal choice for patients with PAMM. However, further studies are required to evaluate the efficacy and clinical utility of this therapeutic regimen. PMID:24765186

    Clinical outcomes after primary graft failure (PGF) remain poor. Here we present a large retrospective analysis (n=23,272) which investigates means to prevent PGF and early detection of patients at high risk. In patients with hematologic malignancies, who underwent their first myeloablative allogeneic hematopoietic cell transplantation, PGF was reported in 1,278 (5.5%), and there was a marked difference in PGFs using peripheral blood stem cell compared to bone marrow grafts (2.5 vs. 7.3%; P<0.001). A 4-fold increase of PGF was observed in myeloproliferative disorders compared to acute leukemia (P<0.001). Other risk factors for PGF included recipient age below 30, HLA-mismatch, male recipients of female donor grafts, ABO-incompatibility, busulfan/cyclophosphamide conditioning, and cryopreservation. In bone marrow transplants, total nucleated cell doses ≤2.4 × 108/kg were associated with PGF (OR 1.39; P<0.001). The use of tacrolimus-based immunosuppression and granulocyte colony-stimulating factor were associated with decreased PGF risk. These data, allow clinicians to do more informed choices with respect to graft source, donor selection, conditioning and immunosuppressive regimens to reduce the risk of PGF. Moreover, a novel risk score determined on day 21 post-transplant may provide the rationale for an early request for additional hematopoietic stem cells. PMID:25772027

    Clinical manifestations between hepatocellular carcinoma (HCC) and extra-hepatic primary malignancy (EHPM) are lack of large-scale study. We enrolled 14555 HCC patients between 1986 and 2013 retrospectively. The EHPM was classified as prior, synchronous and metachronous group based on before, within and after 6 months of HCC diagnosis, respectively. The incidence rate of EHPM is 3.91% (95% confidence interval [CI]: 3.60-4.23%). Urogenital cancers, kidney and bladder, were at unexpected higher ranks. Older in age, Child-Pugh A cirrhosis, negativity of HBsAg and anti-HCV, and earlier BCLC staging are independent factors associated with EHPM. The survival rates of EHPM improve over time and also better than HCC-alone. Cox proportional-hazards regression shows independent poor prognostic factors are age >60, male, AFP levels ≥400 ng/ml, positivity of HBsAg, Child-Pugh B vs. A, Non-metachronous group, respectively, treated with local ablation, transcatheter arterial embolization, radiotherapy and supportive care vs. surgery, respectively, TNM stage IIIA vs. I, and BCLC stages A, B, C and D vs. 0, respectively.

    A 68-year-old woman was admitted to the Peking Union Medical College Hospital with a 6-week history of fever of undetermined origin. The computed tomography scan revealed a space-occupying lesion in the ascending colon and colonic endoscopy revealed a protrusive lesion in the initial segment of the ascending colon, occupying 3/5 of the lumen. Pathological examination of a biopsy specimen revealed malignant fibrous histiocytoma (MFH). The patient then underwent a laparotomy for right hemicolectomy and en bloc lymph node dissection. The histopathological examination confirmed the diagnosis of MFH and administration of adjuvant radiotherapy was decided. MFH is a high-grade sarcoma that rarely arises in the alimentary tract. To the best of our knowledge, there has only been one case of primary colorectal MFH treated by radiotherapy recorded to date, which makes our case the second trial. We herein present a case of MFH in the ascending colon and a review of previous case reports of patients presenting with this unusual type of MFH. PMID:27284436

    Purpose/Objectives To determine whether the perceived level of spirituality in family caregivers of patients with primary malignant brain tumors (PMBTs) changes across the disease trajectory. Design Ongoing descriptive, longitudinal study. Setting Southwestern Pennsylvania. Sample 50 family caregivers of patients with PMBT. Methods Caregivers and care recipients were recruited at time of diagnosis. Participants were interviewed at two subse-quent time points, four and eight months following diagnosis. Main Research Variables Care recipients’ symptoms, neuro-psychologic status, and physical function, as well as caregiver social support. Findings Results showed no significant difference in spirituality scores reported at baseline and eight months (p = 0.8), suggesting that spirituality may be a stable trait across the disease trajectory. Conclusions Spirituality remains relatively stable along the course of the disease trajectory. Reports of caregiver depressive symptoms and anxiety were lower when paired with higher reports of spirituality. Implications for Nursing Clinicians can better identify caregivers at risk for negative outcomes by identifying those who report lower levels of spirituality. Future interventions should focus on the development and implementation of interventions that provide protective buffers such as increased social support. Knowledge Translation Spirituality is a relatively stable trait. High levels of spirituality can serve as a protective buffer from negative mental health outcomes. Caregivers with low levels of spirituality may be at risk for greater levels of burden, anxiety, and stress. PMID:23615145

    The present study aimed to explore how prescription of opioid medication for chronic non-malignant pain (CNMP) is managed in primary care. We used audit as a research tool, and one general practitioner (GP) practice in West London acted as an exemplar. Of the practice population with CNMP, 1% had repeat prescription of at least 12 months duration for opioid analgesics at the time of data collection. These 1% are on highly controlled opioids. Our study showed the following: (1) long-term opioid prescription appears to follow a fluctuating course as opposed to staying the same; (2) we found that medication reviews were done in most cases (85.7%), but the quality of the process is difficult to assess and ascertain; and (3) we identified two incidences where opioid contract was implemented. In both cases, contracts were used as a last chance warning for patients who were already problematic, suggesting that opioid contracts served as a disciplinary tool rather than a preventative measure. Our findings highlight a need for a more structured and specific review of analgesic medication, and a need for a simple and effective way to identify patients at high risk of developing problematic use, to ensure better monitoring and early presentations.

    In 13 patients with primary malignant bone tumors (10 Ewing's sarcoma, 1 parosteal osteosarcoma, 1 adamantinoma recurrence, and 1 MFH) local therapy was performed as intraoperative extracorporeal irradiation and replantation (IEIR) of the involved bone segment (5 tibia, 2 femur, and 6 pelvis). Of the 13 patients (69%), 9 are alive at the time of the follow-up (5 CDF, 4 AWM(treated)) and 4 patients died of disease (DOD). Up to now during the follow-up of 32 months (6-57), no local recurrence was observed in the replanted bone segments. The complication rate was very high (18 complications in 11 of the 13 patients, including 6 cases with complication V degrees according to Ruggieri with loss of the reconstruction). The typical complication is severe local infection necessitating removal of the replant. In cases of mechanical failure, the replanted segment could mostly be preserved by surgical revision and autologous bone grafting. If serious complications can be managed or avoided, functional results can be achieved. IEIR must be seen as an extraordinary reconstruction procedure in cases where established procedures such as endoprosthesis, biological reconstructions, or rotationplasties cannot be used or are refused by the patient.

    The aim of this study was to report a case of concurrent primary malignancies of the breast and nasopharynx and discuss the potential relationship between Epstein-Barr virus (EBV) infection and breast cancer. A 39-year-old female presented with a palpable mass present for 1 year in her left breast. Immunohistochemical staining was performed and the results showed that the tumor cells were immunopositive for the estrogen receptor, progesterone receptor and p53 protein, and markedly positive for C-erb B2. In addition, 30% of the tumor cells were positive for the Ki-67 antigen. Blood test results revealed that EBV-CA-IgG was present and EBV-EA-IgG was reactivated. The patient was diagnosed with breast cancer (T1N0M0) and EBV infection. A mastectomy with axillary clearance was performed on the left breast. Histopathological examination provided evidence of invasive ductal adenocarcinoma. Further evaluation due to epistaxis following the breast surgery resulted in a diagnosis of nasopharyngeal carcinoma (T2N1M0). Histopathology showed a non-keratinizing undifferentiated carcinoma. The patient was treated with chemoradiotherapy for nasopharyngeal carcinoma. Twelve months following surgery and chemoradiotherapy the patient was assessed at the Cancer Hospital of Guangxi Medical University outpatient clinic and no evidence of relapse or metastasis was found. Thus, EBV infection may be involved in the pathogenesis of breast cancer, as observed in nasopharyngeal carcinoma. PMID:22844371

  3. Critical reappraisal of primary osseous composite sarcoma (malignant mesenchymoma) - analysis of four cases and literature review.

    PubMed

    Chow, Louis T C

    2016-06-01

    In accordance with recent terminology, it is proposed that malignant mesenchymoma should be renamed 'composite sarcoma' and defined as 'a sarcoma composed of two or more cellular types each of which is sufficiently differentiated to permit clear recognition of its histogenetic type microscopically, immunohistochemically or ultrastructurally; excluding fibrosarcomatous and high-grade pleomorphic undifferentiated sarcomatous component, dedifferentiated sarcoma and the combination of osteosarcoma and chondrosarcoma which is regarded as a single histogenetic type'. Four cases of primary osseous composite sarcoma (POCS) were identified among 928 primary bone sarcomas. Their age ranged from 10 to 87 years, peak incidence in the second decade with equal sex distribution. Most presented with pain, commonest in the knee, affecting the metaphysis, appearing radiologically as expansile infiltrative osteolytic lesions with cortical erosion, periosteal reaction, variable extent of osteoblastic areas and soft tissue extension. All contained variable amounts of conventional high-grade osteosarcoma with or without chondrosarcoma component; the other constituents were liposarcoma, rhabdomyosarcoma and leiomyosarcoma. In all cases, Ki67 proliferative index was over 35%, there was no CDK4 and MDM2 amplification. The absence of low-grade component supported the de novo origin of POCS rather than derivation from divergent dedifferentiation. The two older patients with hitherto undescribed osteoleiomyosarcoma died 2 and 10 months after operation, whereas the two younger with osteorhabdomyosarcoma and osteoliposarcoma enjoyed disease-free survival at 16 and 6 years after chemotherapy despite the latter showing lung metastasis at presentation. Identification of the different lines of differentiation together with their approximate amounts and histological grades is therefore mandatory for POCS as multi-agent chemotherapy catered for each sarcoma component might offer hope for long

    Advanced gastric cancer is often accompanied by metastasis to the peritoneum, resulting in a high mortality rate. Mechanisms involved in gastric cancer metastasis have not been fully clarified because metastasis involves multiple steps and requires a combination of altered expressions of many different genes. Thus, independent analysis of any single gene would be insufficient to understand all of the aspects of gastric cancer peritoneal dissemination. In this study, we performed a global analysis of the differential gene expression of a gastric cancer cell line established from a primary main tumour (SNU-1) and of other cell lines established from the metastasis to the peritoneal cavity (SNU-5, SNU-16, SNU-620, KATO-III and GT3TKB). The application of a high-density cDNA microarray method made it possible to analyse the expression of approximately 21 168 genes. Our examinations of SNU-5, SNU-16, SNU-620, KATO-III and GT3TKB showed that 24 genes were up-regulated and 17 genes down-regulated besides expression sequence tags. The analysis revealed the following altered expression such as: (a) up-regulation of CD44 (cell adhesion), keratins 7, 8, and 14 (epitherial marker), aldehyde dehydrogenase (drug metabolism), CD9 and IP3 receptor type3 (signal transduction); (b) down-regulation of IL2 receptor γ, IL4-Stat (immune response), p27 (cell cycle) and integrin β4 (adhesion) in gastric cancer cells from malignant ascites. We then analysed eight gastric cancer cell lines with Northern blot and observed preferential up-regulation and down-regulation of these selected genes in cells prone to peritoneal dissemination. Reverse transcriptase–polymerase chain reaction confirmed that several genes selected by DNA microarray were also overexpressed in clinical samples of malignant ascites. It is therefore considered that these genes may be related to the peritoneal dissemination of gastric cancers. The results of this global gene expression analysis of gastric cancer cells

    Incidence of gastrointestinal malignancy is gradually increasing. The aim of the study is to investigate age, sex and relative frequencies of various gastrointestinal malignancies diagnosed between January 2007 and December 2014 in the University of Uyo Teaching Hospital, and in a Private Specialist Laboratory, Uyo, Akwa Ibom State, Nigeria. All histological-diagnosed cases of gastrointestinal malignancies seen during the study period were recruited noting their bio-data and histopathological characteristics. A total of 67 patients aged 6-77 years (mean 58.0, SD 7.4) were enrolled; a male to female ratio of 1.3:1 was recorded. The most common age group and anatomical site affected with gastrointestinal malignancy were 61-70 years (23 cases, 34.3%) and colo-rectum cancers (36 cases, 53.7%). The small intestine and stomach were second and third leading anatomic sites involved in gastrointestinal malignancies, accounting for 13 (19.4%) and 8 (11.9%) cases respectively. Adenocarcinoma accounted for the majority of gastrointestinal malignancies (57 cases, 85.1%). Lymphoma and carcinoid tumor were also common, accounting for 3 (4.5%) cases each. Colorectal carcinoma was the most common type of gastrointestinal malignancies (53.7%) with adenocarcinoma being the predominant histological subtype of gastrointestinal malignancies. PMID:27134715

    Effective communication across the primary/secondary interface is vital for the planning and delivery of appropriate patient care throughout the cancer patient journey. This study describes GPs' views of the communication issues across the primary/secondary interface in relation to ovarian cancer patients using qualitative interviews with purposively sampled general practitioners (GPs) and an audit of hospital medical records of 30 deceased ovarian cancer patients. Issues raised by the GPs related to the content and format of communications, but of most concern was the tardiness. The time lag between dictation and typing letters ranged from 0 to 27 days, with a delay of up to 8 days for signing before transit through various mail systems to the GP. Three stages in the patient journey were characterized by particular issues: (1) in the pre-diagnostic and diagnostic stage was a need for prompt information regarding the results of tests and diagnoses, and clearer guidance on the use of tests and fast-track referrals; (2) in the active treatment phase, when GPs could lose touch with their patients, they needed effective communication in order to provide moral support and crisis management; and (3) when oncology withdrew and the focus of care switched back to the community for the terminal phase, GPs needed information to enable them to pick up the baton of care. There is a need to develop and evaluate interventions aimed at improving the content and speed of communications between secondary and primary care. Such interventions are likely to be complex and might include the greater use of telephone or fax for more selected communications, a review of secretarial support, the use of email, the development of GP designed proformas, the feasibility of patient/carer letter delivery options, nurse-led communication, universal electronic patient records, or a revisiting of the patient-held record.

    Teratomas are rarely seen in adults, and presacral region is an area where they rarely settle in. Similarly, only about 1% of teratomas show malignant transformation. Malignant transformation is often associated with the area where teratoma settles in. Malignant transformation of mediastinal teratomas is more frequent than the ones located in retroperitoneal area and gonad. They most commonly show rhabdomyosarcoma, primitive neuroectodermal tumor, enteric adenocarcinoma, and leukemia transformation. In teratomas showing malignant transformation, the clinical course is aggressive; and survival of patients with metastatic disease is very low. The primary treatment of teratomas with malignant transformations is surgical. Effect of radiotherapy and chemotherapy is not clear in patients, to whom surgical operation cannot be applied, or those who are with residual tumor, even if surgical operation can be applied to them, or those who are at metastatic stage. In this paper, we presented a 76-year-old male patient due to the histologic diagnosis of mucinous adenocarcinoma within teratoma, in whom approximately 7 cm presacral mass was found during the radiographic examination made by the reason of low back pain and pelvic pain.

    Ovarian low-grade serous carcinoma (LGSC) is an entity with distinct pathologic and clinical features. The number of studies on this type of tumor is limited. In this article, we present our experience with 33 cases of ovarian LGSC with primary surgical treatment at our institution. For comparison, a cohort of ovarian high-grade serous carcinoma (HGSC) was also studied. Clinical information was obtained from the patients' charts or from the treating physicians. Hematoxylin and eosin slides were reviewed of 28 available LGSCs, and the following parameters were recorded: presence/absence of a serous borderline tumor (SBT), presence/absence of micropapillary/cribriform pattern (MP/CP), architectural pattern in the invasive component, and presence/absence of desmoplasia or fibrosis. The incidence of ovarian LGSC was 4.7%. LGSC patients ranged in age from 19 to 79 years (mean, 52 y), with 21.2% younger than 40 years. HGSC patients ranged in age from 38 to 90 years (mean, 62 y), with 1.6% younger than 40 years. LGSCs were staged as follows: stage I (2), stage III (23), and stage IV (8). Twenty-eight of 33 LGSC cases had concurrent SBT, with this component accounting for >50% of the neoplasm in 15 cases. In addition, MP/CP was noted in 19 cases. Invasion patterns included micropapillae (93%), cribriform nests (74%), elongated papillae (26%), glandular (44.4%), medium-sized papillae (33.3%), solid nests (22.2%), macropapillae (19%), and single cells (19%). In addition, desmoplasia (44.4%) and fibrosis (37%) were noted. Follow-up data ranging from 13 to 195 months (median 61.2 mo) were available on 30/33 LGSC patients: 18 (60%) were dead of disease; 1 (3.3%) was dead of other cause; 5 (16.7%) were alive with disease; and 6 (20%) had no evidence of disease. Follow-up data from 1 to 169 months (median 48 mo) were available on 185 HGSC patients: 132 (71.4%) were dead of disease; 3 (1.6%) were dead of other cause; 21 (11.4%) were alive with disease; and 29 (15.7%) had no

    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

    Radical surgery is considered not to improve the prognosis of primary malignant melanoma of the vagina (PMMV). This study was carried out to review the general consensus. A systematic review was performed on the basis of data from 10 patients in our cohort and 147 patients in the previous literature. The radicality of the initial surgery (RAINS) score was defined as the total number of points in terms of the resected organs. The target organs were the vagina, vulva, urethra, bladder, uterus, anus, rectum, pelvic lymph nodes, and inguinal lymph nodes. Overall survival (OS) according to the RAINS score was analyzed using the Kaplan-Meier method. Information on tumor stage, size, and depth of invasion was not obtained in 15, 47, and 43% of patients, respectively. The median follow-up period was 18 months. OS with a RAINS score of at least 7 was significantly longer than that with a RAINS score of up to 6 (median survival time, 41 vs. 19 months; log-rank test, P=0.037), despite the fact that the former group included significantly more patients with advanced-stage disease. A significant difference in OS was not found between patients with a RAINS score of at least 6 and up to 5. The therapeutic significance of radical surgery for PMMV has not been assessed appropriately in previous studies because of the lack of comparability among groups and differences in the definitions of surgical radicality. Patients with PMMV might benefit from initial surgery with appropriate surgical radicality, despite incomplete validation of the RAINS score. PMID:26825038

We report a child with a primary MPNST of the lung without NF1. MPNST of the lung has similar clinical and radiologic characteristics as pleuropulmonary blastoma. We suggest to include MPNST of the lung in the differential diagnosis of intrapulmonary masses in children. PMID:16544294

    Objective To evaluate the effect of second-line conservative surgery on in vitro fertilization (IVF) outcome in comparison with IVF without second-line surgery in infertile women with ovarian endometrioma recurrence after primary conservative surgery. Methods In this retrospective cohort study, 121 consecutive IVF/intracytoplasmic sperm injection cycles that were performed after second-line surgery (n=53) or without second-line surgery (control group, n=68) between January 2006 and December 2011 in 121 infertile women with ovarian endometrioma(s) recurrence after primary conservative surgery for moderate to severe endometriosis were included. The two groups were compared in terms of controlled ovarian stimulation and IVF outcomes. Results There were no differences in patients' characteristics between the two groups. Total dose and days of gonadotropins administered were significantly higher in the second-line surgery group than in the control group (P<0.001, P=0.008). The numbers of oocytes retrieved, mature oocytes and grade 1 or 2 embryos were significantly lower in the second-line surgery group (P=0.007, P=0.001, P<0.001, respectively). Clinical pregnancy rate per cycle and embryo implantation rate were also significantly lower in the second-line surgery group of 24.5% and 11.8% compared with 48.5% and 25.3% in the control group (P=0.008, P=0.005, respectively). Conclusion Ovarian response to controlled ovarian stimulation and IVF outcome after second-line surgery is worse than those in IVF cycles without second-line surgery in infertile women with ovarian endometrioma recurrence after primary surgery for moderate or severe endometriosis.

    It may be difficult to distinguish ovarian involvement by a low-grade appendiceal mucinous neoplasm (LAMN) from a primary gastrointestinal-type primary borderline (proliferative) ovarian tumor (IBMT) or an ovarian mucinous tumor arising within a teratoma, particularly when the latter is associated with mucinous ascites/pseudomyxoma peritonei. We noted that LAMNs involving the ovaries show 2 distinctive histologic features, "scalloped" glands and subepthelial stromal clefts, whereas IBMTs more often are associated with reactive cellular stroma and histiocyte aggregates (mucin granulomas). The frequency of these features was investigated in 18 LAMNs (16 with pseudomyxoma peritonei), 18 primary IBMTs, and 6 teratoma-associated mucinous tumors (selected on the basis of associated pseudomyxoma peritonei). Scalloped glands and subepithelial clefts were identified in 17 and 16 LAMNs, respectively, and in 3 and 7 IBMTs, respectively. Conversely, reactive stroma and histiocyte aggregates were present in 2 and 0 LAMNs, respectively, and in 11 and 10 IBMTs, respectively. LAMNs were often bilateral (12/18 cases) and they more frequently showed mucin dissection of the ovarian stroma and tall mucin-rich (hypermucinous) epithelial cells compared with IBMTs. Our findings suggest that scalloped glands, subepithelial clefts, cellular stroma, and histiocyte aggregates may be useful additional morphologic parameters to help distinguish these tumor types. However, teratoma-associated mucinous neoplasms can show identical histologic features to those of LAMNs involving the ovary, and therefore accurate diagnosis of such cases requires careful macroscopic and microscopic examinations of the ovaries together with complete histologic assessment of the appendix.

    Consistent with universally established practice, it has been customary in our unit to subject patients with clinically suspected or biopsy proven ovarian cancer to a large number of preoperative investigations. This is in order to determine metastases, surgical strategy, and exclusion of pelvic kidney. This study presents a comparison of the preoperative ultrasonography, computerized tomography, intravenous pyelography, chest X-ray, liver and bone scintigraphy, and barium enema results performed in 100 cases with the operative findings. These investigations were found to have marginal value in determining extent of disease, upper gastrointestinal metastatic deposits, and the need for or extent of bowel resection. It is concluded that such a standard workup, which is time-consuming and distressing for an already anxious patient, is not cost effective for a surgical procedure which is ultimately determined at laparotomy.

    Purpose: To evaluate the clinical efficacy of the polyurethane-covered Nitinol Strecker stent in the treatment of patients with malignant biliary obstruction.Methods: Twenty-three covered stents produced by us were placed in 18 patients with malignant biliary obstruction. Jaundice was caused by cholangiocarcinoma (n = 5), pancreatic cancer (n = 6), gallbladder cancer (n = 4), metastatic lymph nodes (n = 2), and tumor of the papilla (n 1).Results: The mean patency period of the stents was 37.5 weeks (5-106 weeks). Recurrent obstructive jaundice occurred in two patients (11%). Adequate biliary drainage over 50 weeks or until death was achieved in 17 of 18 patients (94.4%). Late cholangitis was observed in two patients whose stents bridged the ampulla of Vater. Other late severe complications were not encountered.Conclusion: Although more study is necessary, our results suggest the clinical efficacy of our covered Nitinol Strecker stent in the management of obstructive jaundice caused by malignant diseases.

    The Authors have reported the cytological patterns of malignant primitive uterine fibrous histiocytoma of a 57 year old woman. The endometrial cytological sampling was performed by an aspiration technique using a feeding-tube; a necrotic-haemorrhagic background filled with hymphocytes and polymorphonuclear leukocytes, and a mixture of highly anaplastic histiocytic and fibroblastic type cells, associated with undifferentiated small round cells, has been described. The result of the histological examination performed on the surgical specimen was the following: polymorphic malignant neoplasia characterized by spindle-like and giant plurinucleated cells, phagocytosis features, endoluminal polypoid growth, wide infiltration of the miometrium two thirds deep, vascular space invasion of the uterine wall and the hilus of the ovaries. The histological features and immunohistochemical analysis were consistent with malignant fibrous histiocytoma in the pleomorphic variety. PMID:1965802

    Objectives To identify predictors of mortality within 1 year after primary surgery for ovarian cancer. Design Prospective nationwide cohort study from 1 January 2005 to 31 December 2012. Setting Evaluation of data from the Danish Gynaecology Cancer Database and the Danish Civil Registration System. Participants 2654 women who underwent surgery due to a diagnosis of primary ovarian cancer. Outcome measures Overall survival and predictors of mortality within 0–180 and 181–360 days after the primary surgery. Examined predictors were age, preoperative American Society of Anesthesiologists (ASA) score, body mass index (BMI), International Federation of Gynaecology and Obstetrics (FIGO) stage, residual tumour tissue after surgery, perioperative blood transfusion and calendar year of surgery. Results The overall 1-year survival was 84%. Within 0–180 days after surgery, the 3 most important predictors of mortality from the multivariable model were residual tumour tissue >2 cm versus no residual tumour (HR=4.58 (95% CI 3.20 to 6.59)), residual tumour tissue ≤2 cm versus no residual tumour (HR=2.50 (95% CI 1.63 to 3.82)) and age >64 years versus age ≤64 years (HR=2.33 (95% CI 1.69 to 3.21)). Within 181–360 days after surgery, FIGO stages III–IV versus I–II (HR=2.81 (95% CI 1.75 to 4.50)), BMI<18.5 vs 18.5–25 kg/m2 (HR=2.08 (95% CI 1.18 to 3.66)) and residual tumour tissue >2 cm versus no residual tumour (HR=1.84 (95% CI 1.25 to 2.70)) were the 3 most important predictors. Conclusions The most important predictors of mortality within 1 year after surgery were residual tumour tissue (0–180 days after surgery) and advanced FIGO stage (181–360 days after surgery). However, our results suggest that the surgeon should not just aim at radical surgery, but also pay special attention to comorbidity, nutritional state, age >64 years and the need for perioperative blood transfusion.

    Coexisting primary malignancies have been described at length in the literature. While double primary malignancies are relatively common, three synchronous primary malignancies are extremely rare. We describe a case of a 60-year-old woman undergoing surgery for a known endometrial carcinoma. The patient also had a renal mass that was identified as a clear cell renal cell carcinoma and an additional lesion in the colon that was a mucinous adenocarcinoma. Further genetic testing of the patient revealed a deleterious MSH6 mutation suggestive of Lynch syndrome. The patient had all tumors addressed by minimally invasive techniques at the same operative intervention. It is important to consider hereditary cancer syndromes in women with a strong family history presenting with synchronous multiple primary malignancies. A multidisciplinary surgical approach is key to best practices and optimal patient outcomes. PMID:27331139

    A 62-year-old woman was diagnosed with primary left breast cancer during a follow-up for an ovarian tumor. She had at first undergone surgical resection of an ovarian tumor, and a pathological examination had revealed ovarian cancer. Gynecologists decided to treat her ovarian cancer with chemotherapy, and we were initially planning to provide treatment for breast cancer after that was completed. Sentinel lymph node biopsy performed before chemotherapy revealed no axillary metastases. The patient received six courses of intravenous PTX (175 mg/m2 on day 1, every 3 weeks) and intravenous CBDCA (AUC6 on day 1, every 3 weeks) as combination therapy. Abdominal lymph node dissection was performed between chemotherapy courses 3 and 4. The lump in the left breast showed partial clinical response, and partial resection of the left breast was performed after completion of chemotherapy. In Japan, few cases of primary breast cancer treated preoperatively using carboplatin-containing regimens have been described. PMID:22705705

    Massive ovarian edema is a rare tumor-like condition found in young women resulting from accumulation of fluid mostly due to partial or intermittent torsion of the ovary or secondary, to a preexisting ovarian lesion. We report a case of a 13-year-old girl presenting with an ovarian mass measuring 16 cm. CA-12-5 levels were slightly elevated. Concerns regarding underlying malignancy led to salpingo-oophorectomy. Pathological evaluation revealed a massive ovarian edema and multiple thromboses of ovarian veins. Differentiating massive ovarian edema from malignant ovarian tumor is crucial to prevent patients from undergoing unnecessary surgery. PMID:23649810

    Ovarian cancer is the most common cause of death among gynecological malignancies. We discuss different types of clinical and nonclinical features that are used to study and analyze the differences between benign and malignant ovarian tumors. Computer-aided diagnostic (CAD) systems of high accuracy are being developed as an initial test for ovarian tumor classification instead of biopsy, which is the current gold standard diagnostic test. We also discuss different aspects of developing a reliable CAD system for the automated classification of ovarian cancer into benign and malignant types. A brief description of the commonly used classifiers in ultrasound-based CAD systems is also given. PMID:25230716

    Women constitute the majority of the aging United States (US) population, and this has substantial implications on cancer population patterns and management practices. Breast cancer is the most common women's malignancy, while ovarian cancer is the most fatal gynecological malignancy in the US. In this review, we focus on these subsets of women's cancers, seen more commonly in postmenopausal and elderly women. In order to systematically investigate the complexity of cancer progression and response to treatment in breast and ovarian malignancies, we assert that integrated mathematical modeling frameworks viewed from a systems biology perspective are needed. Such integrated frameworks could offer innovative contributions to the clinical women's cancers community, as answers to clinical questions cannot always be reached with contemporary clinical and experimental tools. Here, we recapitulate clinically known data regarding the progression and treatment of the breast and ovarian cancers. We compare and contrast the two malignancies whenever possible in order to emphasize areas where substantial contributions could be made by clinically inspired and validated mathematical modeling. We show how current paradigms in the mathematical oncology community focusing on the two malignancies do not make comprehensive use of, nor substantially reflect existing clinical data, and we highlight the modeling areas in most critical need of clinical data integration. We emphasize that the primary goal of any mathematical study of women's cancers should be to address clinically relevant questions.

    Primary malignant spinal tumors and solitary vertebral metastases of selected tumor entities in the thoracolumbar spine are indications for total en bloc spondylectomy (TES). This study aimed to describe our oncological and surgical management and to analyze the treatment results by management with TES for extra- and intracompartmental solitary spinal metastases and primary malignant vertebral bone tumors. In 15 patients (3 malignant bone tumors and 12 solitary metastases), tumors were distributed in the thoracic (n = 8) and lumbar (n = 7) spine. Tumors were classified as intra- (n = 8) and extracompartmental (n = 7). All patients underwent TES via a laterally extended posterior approach followed by dorsoventral reconstruction. Function and quality of life were assessed by Oswestry disability index (ODI) and SF-36 score. At follow-up (100%; mean: 33 ± 22 months), 11 patients had no evidence of disease. Two patients were alive with the disease and two were dead of the disease (no primary bone tumors). Histology revealed negative margins (R0) in all patients with wide (n = 11) and marginal (n = 4) resections. Two patients developed pulmonal metastases of which they died at 4 and 16 months of survival. No local recurrence was observed. Major complications did not occur. TES resulted in an acceptable outcome in the quality of life and function. TES is a demanding procedure reaching wide to marginal resections in a curative approach. In conjunction with multimodal therapies, local recurrences can effectively be prevented while control of distant disease needs to be improved. Proper selection of adequate patients combined with careful surgical planning are prerequisites for low complication rates, acceptable function and improved overall prognosis. PMID:17252218

    Integrin β1 (ITGB1) is frequently upregulated in ovarian cancer, and promotes ovarian tumorigenesis and cancer progression. However, the effects of ITGB1 inhibition on ovarian cancer progression and anticancer therapy remain to be elucidated. The results of the present study indicated that ITGB1 was upregulated in HO-8910 and HO-8910PM ovarian cancer cell lines, and knockdown of ITGB1 using short hairpin RNA markedly increased tumor cell apoptosis, decreased tumor cell adhesion and migration, and reduced tumor cell invasion by suppressing matrix metalloproteinase (MMP)-2 and MMP-9 expression. Furthermore, the results of the present study provided evidence regarding the role of ITGB1 inhibition in bevacizumab anticancer therapy. The activation of signal transducer and activator of transcription 1 (STAT1) by focal adhesion kinase (FAK) is involved in integrin-mediated cell migration and adhesion. In the present study, the expression levels of FAK were markedly upregulated in ovarian cancer. The adherence and migratory potentials of ovarian cancer cells were significantly reduced when the FAK/STAT1 signaling pathway was inhibited by fludarabine. The results of the present study demonstrated that ITGB1 inhibition effectively reduced tumorigenesis and disease exacerbation, and contributed to bevacizumab anticancer therapy via the FAK/STAT1 signaling pathway, suggesting that inhibition of ITGB1 is a potential novel therapeutic strategy for ovarian carcinogenesis.

    Oral malignant melanoma (OMM) is a rare tumor of melanocytic origin, accounting for 20-30% of malignant melanomas at the mucosal surface and 16% intra-orally. Hard palate and maxillary gingiva are the most common involved sites. In this case series, we present varying patterns of presentation of three cases of OMM with one case of distant metastasis. All cases in the current series presented at an advanced stage and died within a year of diagnosis. In conclusion, due to the aggressive clinical course and poor prognosis of this deadly lesion, it is of paramount importance to maintain a high index of suspicion for early detection and diagnosis for any pigmented lesion in the oral cavity.

    The first clinical trials of photodynamic therapy (PDT) of cancer with two photosensitizers, PHOTOHEME and PHOTOSENS, were started in P.A. Hertzen Research Oncological Institute (Moscow, Russia) in 1992 and 1994. Up to now, 208 patients with primary, recurrent and metastatic malignant tumors (469) of skin (34 patients/185 tumors), breast cancer (24/101), head and neck (30/31), trachea and bronchus (31/42), esophagus (35/35), stomach (31/32), rectum (4/4), vagina and uterine cervix (7/8) and bladder (12/31) have been treated by PDT. One-hundred-thirty patients were injected with PHOTOHEME, 64 patients were injected with PHOTOSENS, 14 patients were injected with PHOTOHEME and PHOTOSENS. Totally, 302 courses of treatment were performed: 155 patients had one course and 53 patients were subjected to two to nine PDT sources with intervals from 1 to 18 months. A therapeutic effect of a one-course and multi- course PDT of malignant tumors (respiratory, digestive and urogenital systems) was evaluated clinically, histologically, roentgenologically, sonographically and endoscopically. The biochemical, hematological and immunological investigations were performed for all the patients in dynamics. Results of our study showed that a multi-course PDT method seems to be perspective in treatment of malignant tumors of basic localizations.

    The introduction of fluorescence-guided resection of primary malignant brain tumors was a milestone in neurosurgery. Deep-seated malignant brain tumors are often not approachable for microsurgical resection. For diagnosis and therapy, new strategies are recommended. The combination of endoscopy and 5-aminolevulinic acid-induced protoporphyrin IX (5-ALA-induced Pp IX) fluorescence-guided procedures supported by neuronavigation seems an interesting option. Here the authors report on a combined approach for 5-ALA fluorescence-guided biopsy in which they use an endoscopy system based on an Xe lamp (excitation approximately λ = 407 nm; dichroic filter system λ = 380-430 nm) to treat a malignant tumor of the thalamus and perform a ventriculostomy and septostomy. The excitation filter and emission filter are adapted to ensure that the remaining visible blue remission is sufficient to superimpose on or suppress the excited red fluorescence of the endogenous fluorochromes. The authors report that the lesion was easily detectable in the fluorescence mode and that biopsy led to histological diagnosis. PMID:21166571

    To investigate the effects of electroacupuncture (EA) on serum FSH, E2, and LH levels, women with primary ovarian insufficiency (POI) were treated with EA once a day, five times a week for the first four weeks and once every other day, three times a week, for the following two months, and then were followed up for three months. Serum E2, FSH, and LH levels were measured at baseline, at the end of treatment, and during followup. A total of 11 women with POI were included in this prospective consecutive case series study. Compared with baseline, patients' serum E2 increased, FSH decreased, and LH decreased (P = 0.002, 0.001, and 0.002, resp.) after EA treatment, and these effects persisted during followup. With treatment, 10 patients resumed menstruation (10/11, 90.91%), whereas one patient remained amenorrhea. During followup, two patients, including the one with amenorrhea during treatment, reported absence of menstruation. Temporary pain occurred occasionally, and no other adverse events were found during treatment. The results suggest that EA could decrease serum FSH and LH levels and increase serum E2 level in women with POI with little or no side effects; however, further randomized control trials are needed.

    Objective To assess patients' preferences of the timing of referral for genetic counseling and testing in relation to the diagnosis, treatment and recurrence of ovarian, tubal, or primary peritoneal cancers. Methods/Materials Ninety-two patients who underwent counseling and testing by one certified genetic counselor were identified. Introductory letter, consent form and questionnaire were mailed to gather information regarding factors influencing the decision to undergo genetic counseling and testing and opinions regarding optimal timing. Medical records were reviewed for demographic and clinical data. Results Of 47 consenting women, 45 underwent testing. Eight (18%) were found to have a genetic mutation. Women lacked consensus about the optimal time for referral for and to undergo genetic testing, though women with stage I disease preferred testing after completion of chemotherapy. Most women were comfortable receiving the results by phone, but 1/3 preferred an office visit. Conclusions Patients' views regarding the best time to be referred for and undergo counseling and testing varied greatly. Due to the high mortality of this disease, clinicians should discuss referral early and personalize the timing to each patient. The subset of patients who prefer results disclosure during an office visit should be identified at the time of their initial counseling. PMID:23748176

    The mortality rate of ovarian cancer remains high due to late diagnosis and recurrence. A fundamental step toward improving detection and treatment of this lethal disease is to understand its origin. A growing number of studies have revealed that ovarian cancer can develop from multiple extra-ovarian origins, including fallopian tube, gastrointestinal tract, cervix and endometriosis. However, the mechanism leading to their ovarian localization is not understood. We utilized in vitro, ex vivo, and in vivo models to recapitulate the process of extra-ovarian malignant cells migrating to the ovaries and forming tumors. We provided experimental evidence to support that ovulation, by disrupting the ovarian surface epithelium and releasing chemokines/cytokines, promotes the migration and adhesion of malignant cells to the ovary. We identified the granulosa cell-secreted SDF-1 as a main chemoattractant that recruits malignant cells towards the ovary. Our findings revealed a potential molecular mechanism of how the extra-ovarian cells can be attracted by the ovary, migrate to and form tumors in the ovary. Our data also supports the association between increased ovulation and the risk of ovarian cancer. Understanding this association will lead us to the development of more specific markers for early detection and better prevention strategies. PMID:25135607

    The objective of this study was to analyze three ureteral stenting techniques in patients with malignant ureteral obstructions, considering the indications, techniques, procedural costs, and complications. In the period between June 2003 and June 2006, 45 patients with bilateral malignant ureteral obstructions were evaluated (24 males, 21 females; average age, 68.3; range, 42-87). All of the patients were treated with ureteral stenting: 30 (mild strictures) with direct stenting (insertion of the stent without predilation), 30 (moderate/severe strictures) with primary stenting (insertion of the stent after predilation in a one-stage procedure), and 30 (mild/moderate/severe strictures with infection) with secondary stenting (insertion of the stent after predilation and 2-3 days after nephrostomy). The incidence of complications and procedural costs were compared by a statistical analysis. The primary technical success rate was 98.89%. We did not observe any major complications. The minor complication rate was 11.1%. The incidence of complications for the various techniques was not statistically significantly. The statistical analysis of costs demonstrated that the average cost of secondary stenting ( Euro 637; SD, Euro 115) was significantly higher than that of procedures which involved direct or primary stenting ( Euro 560; SD, Euro 108). We conclude that one-step stenting (direct or primary) is a valid option to secondary stenting in correctly selected patients, owing to the fact that when the procedure is performed by expert interventional radiologists there are high technical success rates, low complication rates, and a reduction in costs.

    A 10-year-old female striped skunk (Mephitis mephitis) was admitted with severe abdominal distension and lethargy. Cytological examination of the peritoneal fluid revealed activated mesothelial cells. At necropsy, numerous growing together, projecting, 2 to 20 mm in diameter tawny to white masses were scattered throughout the peritoneum including the mesentery, omentum and intestinal serosa. Microscopically, the tumor was composed of prominent papillo-tubular structures, and immunohistochemically, the spindle to polygonal-shaped tumor cells with nuclear polymorphism were strongly reactive for calretinin. Based on those diagnostic features, the neoplasia was diagnosed as malignant mesothelioma. This is the first case report of mesothelioma in the skunk. PMID:26568187

    Pulmonary embolism (PE) is a common cause of morbidity and mortality in hospitalized patients. Malignancy, prolonged recumbence, and chemotherapy are renowned risk factors for development of clinically significant PE. Cancer exerts a multitude of pathophysiological processes, for example, hypercoagulability and abnormal vessels with sluggish circulation that can lead to PE. One of the peculiar characteristics of tumor cells is their ability to reach the circulation and behave as blood clot—not a metastasis-occluding the pulmonary circulation. We present a case of fatal pulmonary embolism diagnosed histologically to be due to tumor cell embolism. PMID:25478243

    Breast cancer is known to metastasise to different organs in the body, but an initial presentation of breast cancer with loin pain secondary to a metastatic renal mass is extremely rare. We report a 58-year-old woman who presented with recurrent left loin pain due to a metastatic deposit of invasive lobular carcinoma of the breast. The detection of a renal mass on computed tomography led to the assumption of a renal pelvic malignancy. The diagnostic dilemma posed by the detection of a breast mass during staging and the usefulness of immunohistochemistry in the confirmation of diagnosis are discussed. PMID:23984034

    A 30-year-old man who had a painless mass in the right scrotum since 5 years ago underwent biopsy followed by right high orchiectomy. The tumor originating from the epididymis was histologically diagnosed as a malignant lymphoma (a diffuse large B-cell lymphoma). The tumor grew very slowly even though the MIB-1 index was more than 90%. The patient underwent six courses of R-CHOP chemotherapy, intrathecal administration of methotrexate, and radiation therapy to the contralateral testis. Currently, 10 months after surgery, the patient has shown no clinical evidence of recurrence. PMID:26790768

    The CT findings after interstitial radiation therapy for brain tumors have not been extensively described. We evaluated retrospectively the CT scans of 13 patients who were treated with brachytherapy for malignant glioma. We found no typical CT appearance that differentiates recurrent tumor from radiation effect. After undergoing brachytherapy, eight of the 13 patients scanned demonstrated enhancement of brain tissue beyond the margins of the original enhancing tumor mass. In most cases, the pattern of enhancement diminished and extended more peripherally from the central necrotic area with time. We also report a new CT finding of focal calcification developing at the site of the radioactive implant.

    Superficial cancer in the Sudan accounted for 17·2% of all malignant tumours examined histologically during the period 1962-72 inclusive. Of the 4 pathological types studied, squamous cell carcinoma was the commonest (63·3% of all superficial cancers) followed by malignant melanoma (18·8%) and basal cell carcinoma (14·9%) whilst Kaposi's sarcoma formed only 3% of the total. Generally, twice as many cases occurred in males as in females, with the exception of Kaposi's sarcoma where all the patients were males. Although a relatively high proportion of cases occurred in the young age groups, the age-specific incidence was noted to increase with age. Similarities and differences in the anatomical site of tumours compared with European and African series were noted. Certain differences emerged in the geographical distribution of these tumours in the Northern and Southern regions of the Sudan—regions which differ both ethnologically and geographically—thus suggesting possible roles played by racial and environmental factors in this respect.

    As the primary female sex steroid hormones, estrogens and progesterone play important roles to regulate growth, differentiation, and function of a broad range of target tissues in the human body and maintain the function of female reproductive tissues. Ovarian cancer is the most cause of cancer death in gynecological malignancy. Despite enormous outcomes in the understanding of ovarian cancer pathology, this disease has resulted in poor survival rates since most patients are asymptomatic until the disease has been metastasized. The exact molecular events leading to metastasis of ovarian tumor cells have not yet been well elucidated, although it is recognized that the acquisition of capacity for migration and invasiveness would be a necessary prerequisite. During metastasis, epithelial-mesenchymal transition (EMT) is an important process, in which epithelial cells lose their intracellular adhesion and cell polarity and acquire increased motility and invasive properties to become mesenchymal like cells. The process of cancer cells to undergo EMT is regulated through the up- and down- regulation of a multiple cellular markers and signaling proteins. In this review, we focused the roles of women sex steroid hormones, estrogen and progesterone, in ovarian cancer, especially the ovarian cancer undergoing EMT and metastatic process. All things considered, we may suggest that progesterone is a potent hormone which inhibits the growth of human ovarian cancer cells and development to metastasis whereas estrogen may act as a risk factor of ovarian cancer progression and that progesterone therapy may be an alternative clinically effective tool for the treatment of human ovarian cancer.

    Objective Activation and dimerization of the ERBB family play a role in the pathogenesis and progression of ovarian cancer. We conducted a phase II trial to evaluate the activity and tolerability of lapatinib in patients with recurrent or persistent epithelial ovarian cancer (EOC) and to explore the clinical value of expression levels of epidermal growth factor receptors (EGFR), phosphorylated EGFR, HER-2/neu, and Ki-67, and the presence of EGFR mutations. Methods Eligible patients had recurrent or persistent EOC or primary peritoneal carcinoma, measurable disease, and up to 2 prior chemotherapy regimens for recurrent disease. Patients were treated with lapatinib 1500 mg/day. The primary endpoint of efficacy was 6-month progression free survival (PFS). Results Twenty-five of 28 patients were eligible and evaluable for analysis of efficacy and toxicity. Two (8.0%) were alive and progression-free at 6 months. No objective responses were observed. There were 1 grade 4 toxicity (fatigue) and few grade 3 toxicities. Associations between Ki-67 with prior platinum-free interval, PFS, and a polymorphism in EGFR were suggested. Conclusions Lapatinib has minimal activity in recurrent ovarian cancer. Ki-67 expression may be associated with prior PFS and a polymorphism in EGFR exon 20 (2361G>A, Q787Q). PMID:22037316

    Background and aim This study aimed at determining whether there is a risk regarding the development of second primary malignancies after patient exposure to the low and medium radioiodine activity used during the treatment of differentiated thyroid cancers (DTC). Methods Second primary malignancies that occurred after DTC were detected in 1,990 patients treated between 1970 and 2003. The mean long-term follow-up period was 182 months. Results Radioiodine I-131was administrated at a mean dose of 63.2 mCi. There were 93 patients with at least one second primary malignancy. The relative risk of development of second malignancy in DTC patients was increased (p<0.0001) for breast, uterine and ovarian cancers compared with the general population. Conclusions The overall risk concerning the development of second primary malignancies was related to the presence of DTC, but not to exposure to the low and medium activities of radioiodine administered as adjuvant therapy.

    An increased number of adrenal tumors are now diagnosed due to the increased number of abdominal CT scans being performed. We present the first case of malignant lymphoma combined with clinically "silent" pheochromocytoma in the same adrenal gland. An abdominal CT scan demonstrates unilateral adrenal lesion which suggests pheochromocytoma or adrenal carcinoma. Laboratory examinations revealed a slight increase of 24-h urine vanillylmandelic acid and 24-h urinary methanephrine excretion. Histological examination revealed two intermingled tumor cell proliferations-diffuse B cell lymphoma and pheochromocytoma.Unexpected coexistence of catecholamine-producing tumor with the other adrenal lesion can lead to serious complications of diagnosis and treatment. The adequate preparation for surgery can protect patient from threatening catecholamine crisis. PMID:26419235

    Malignant astrocytomas of the cerebellum are rare tumors which can occur in children. During the last 20 years, 13 patients with this diagnostic received postoperative irradiation at the University of Rochester Cancer Center. The median age of patients was 9.8 years, the male-to-female ratio was 1.6, and the median survival was 20 months. Six patients treated with cranial irradiation (CI) had a median survival of 10 months and 5/6 developed spinal subarachnoid metastases. Seven patients treated with craniospinal irradiation (CSI) had a median survival of 48 months; none has developed spinal metastases. The recommended treatment with CSI resembles that of medulloblastoma, as it is tailored to the spread and behaviorial patterns of these rare neoplasms.

    We report a case of testicular malignant lymphoma in a hemodialysis patient. A 65-year-old man who had been undergoing hemodialysis for 8 years and 10 months consulted our hospital with right testicular enlargement in August 2012. Under a diagnosis of testicular cancer from manipulation test and ultrasonography, high orchiectomy was performed. Computed tomography showed swelling of the retroperitoneal lymph nodes. Histopathological examination revealed diffuse, non-Hodgkin B-cell lymphoma, CD20+. R-CHOP chemotherapy was initiated and retroperitoneal lymph node swelling completely disappeared after 1 cycle of chemotherapy. After completing 2 cycles of chemotherapy, the patient developed interstitial pneumonia, and thus radiotherapy to the retroperitoneal space including the left testis was performed. As of July 2014, the patient remains alive without recurrence. PMID:25812596

    Hydrosalpinx in postmenopausal woman is rare. Most commonly it is due to primary ovarian malignancy with fallopian tube involvement or primary fallopian tube carcinoma. But hydrosalpinx with no malignancy in the fallopian tube, associated with synchronous malignancy of ovary and endometrium is rare. In a postmenopausal women, hydrosalpinx is commonly due to fallopian tube malignancy or rarely pelvic inflammatory disease. We present a rare and very interesting case of 65-year-old nulliparous postmenopausal women with bilateral hydrosalpinx and pyometra who was found to have papillary serous adenocarcinoma of the ovary and endometroid adenocarcinoma of endomertrium with normal fallopian tube. One should always suspect genital malignancy with this presentation, especially in this age group.

    A woman was operated on for a nonepithelial malignant tumor of the left leg and subsequently, for an epithelial carcinoma of the right breast and a borderline malignant tumor of the right ovary. She also developed a giant cavernous hemangioma that caused disseminated intravascular coagulation syndrome, which necessitated a left trisegmentectomy of the liver. Her family history suggested a hereditary predisposition to diverse malignant neoplasms, and also to giant cavernous hemangioma of the liver. Immunological evaluation disclosed selective inhibition of natural killer cell activity. Hormonal and hereditary factors are discussed in relation to the development of multiple primary tumors and giant cavernous hemangioma of the liver. PMID:2724721

    Ovarian cancer is the most common cause of gynecologic cancer death. Both morphologically and immunohistochemically, metastatic mucinous tumors are the best mimickers of mucinous ovarian tumors; its pathogenesis still remains a mystery. PAX2 and PAX8 immunohisyochemistries are useful for differentiating numerous primary tumour types from metastatic ones. There are few studies in literature about PAX expressions in mucinous and seromucinous tumors. None of these are takes into account the histologic type (whether it is seromucinous or mucinous) or the metastatic origin. With this purpose hematoxylin and eosine slides of ovarian mucinous and seromucinous tumors were re-evaluated and one block was chosen for each case. The study included 76 ovarian mucinous and seromucinous tumors of the ovary reported in Hacettepe University department of pathology between 2000 and 2013. Tissue microarray (TMA) was designed from the chosen blocks, PAX2, PAX8, CDX2 immunostains was preformed to the TMA slides. As a result, most of the metastatic cases were negative for PAX2 (91.2 %) and PAX8 (86.3 %), many were diffusely and strongly positive for CDX2 (68.2 %). Seromucinous tumors were devoid of CDX2 expression; but all cases (except one) displayed strong and diffuse positivity with PAX8. In other words differing from mucinous tumors, seromucinous tumors show strong PAX8 positivity-similar to serous tumors. This study shows that PAX8 and CDX2 could be useful in differentiating primary mucinous from metastatic tumor. Furthermore unlike the homogeneity in seromucinous tumors for PAX8 and CDX2 mucinous tumors shows heterogeneity with different expression patterns. PMID:26797858

    Background The omega-3 fatty acid (ω-3 fatty acid) such as eicosapentaenoic acid (EPA) is currently used in the clinic as a nutritional supplement in the treatment of poly- cystic ovarian syndrome (PCOS). The present study was designed to investigate the ef- fect of EPA on the expression levels of peroxisome proliferator-activated receptor gamma (PPARγ) and cytochrome P450 aromatase (encoded by the CYP-19) in primary cultured granulosa cells (GC) from patients undergoing in vitro fertilization (IVF), and also to compare these effects with those in GC of PCOS patients. Materials and Methods In this experimental study, human GC were isolated, pri- mary cultured in vitro, exposed to a range of concentrations of the EPA and in- vestigated with respect to gene expression levels of PPARγ and CYP-19 using real time-polymerase chain reaction (PCR). The participants (n=30) were the patients admitted to the IVF Center in February-March 2013 at Alzahra Hospital, Tabriz, Iran, who were divided into two groups as PCOS (n=15) and non-PCOS (n=15) women (controls). Results All doses of the EPA significantly induced PPARγ mRNA gene expression level as compared to the control recombinant follicle stimulating hormone (rFSH) alone condi- tion. High doses of EPA in the presence of rFSH produced a stimulatory effect on expres- sion level of PPARγ (2.15-fold, P=0.001) and a suppressive effect (0.56-fold, P=0.01) on the expression level of CYP-19, only in the PCOS GC. Conclusion EPA and FSH signaling pathway affect differentially on the gene ex- pression levels of PPARγ and CYP-19 in PCOS GC. Altered FSH-induced PPARγ activity in PCOS GC may modulate the CYP-19 gene expression in response to EPA, and possibly modulates the subsequent steroidogenesis of these cells. PMID:26246878

    Objective Low androgen levels occur in women with primary ovarian insufficiency(POI) and could contribute to mood and behavioral symptoms in this condition. We examined the effects of physiologic testosterone (T) replacement therapy added to standard estrogen/progestin replacement therapy (EPT) on quality of life, self-esteem, and mood in women with POI. Methods 128 women with 46XX spontaneous POI participated in a 12 month randomized, placebo-controlled, parallel-design investigation of the efficacy of T augmentation of EPT. Quality of life, self-esteem, and mood symptoms were evaluated with standardized rating scales and a structured clinical interview. Differences in outcome measures between the T and placebo treatments were analyzed by Wilcoxon rank-sum tests. Results No differences were found in baseline characteristics including serum hormone levels(P >0.05). Baseline mean(SD) CES-D scores were 10.7(8.6)(T) and 9.2(7.8)(placebo) (P = 0.35). After 12 months of treatment, measures of quality of life, self-esteem, and the presence of mood symptoms did not differ between treatment groups. Serum T levels achieved physiologic levels in the T group and were significantly higher compared to placebo (P < 0.001). Baseline T levels were not associated with either adverse or beneficial clinical effects. Conclusions The 150 microgram T patch achieves physiologic hormone levels in women with POI. Our findings suggest that augmentation of standard EPT with physiologic testosterone replacement in young women with POI neither aggravates nor improves baseline reports of quality of life, or self-esteem and had minimal effect on mood. Other mechanisms might play a role in the altered mood that accompanies this disorder. PMID:24473536

We present a case here of synchronous primary laryngeal squamous cell carcinoma (SCC) and malignant fibrous histiocytoma (MFH) in a patient with hoarseness though with no history of exposure to radiation. Clinical, intraoperative, and histopathological findings in this patient are discussed. Methods Wide laser excision of the left supraglottic lesion and laser cordectomy of the right true vocal cord were performed. Results The patient presented with a recurrence of the ΜFH alone (with no recurrence of the SCC) two months after the first operation and was managed with an extended second look laser cordectomy. The patient is under regular follow-up and remained disease-free nine months from diagnosis. Conclusions Our results show that early-stage simultaneous tumours of the larynx and particularly MFH and SCC can be treated efficiently with endoscopic laryngeal surgery alone. Close follow-up is of paramount importance because of the aggressive nature of MFH. PMID:27170836

    Malignant fibrous histiocytoma (MFH) is the most common soft tissue sarcoma of adults, but its presence in the breast is rare. We report a case of primary inflammatory MFH in a 72-year-old Caucasian female with no previous medical history and no prior radiation exposure. She presented with a palpable mass that was suspicious for malignancy on mammography. Histologic evaluation of the core needle biopsy revealed sheets of large, pleomorphic neoplastic cells within a dense background of acute and chronic inflammatory cells. The neoplastic cells exhibited a moderate to abundant amount of finely vacuolated cytoplasm and atypical nuclei with vesicular nuclear chromatin and prominent nucleoli. Mitotic activity was readily identified, and foci of necrosis were noted. The neoplastic cells were immunoreactive with CD68, alpha 1-antitrypsin, alpha 1-antichymotrypsin, and vimentin. The diagnosis of MFH was rendered after thorough microscopic examination of the entire mass following mastectomy. MFH of the breast is a diagnosis of exclusion. The definitive treatment of MFH is surgical, either with wide local excision or total mastectomy. The roles of sentinel lymph node biopsy, axillary lymph node dissection, chemotherapy, and radiation have yet to be definitively clarified. The prognosis of MFH of the breast is generally poor.

    We report a constitutional point mutation of codon 278 in exon 8 of the TP53 gene that has not yet been described as a germ-line mutation. A 52-year-old female developed multiple primary malignancies (liposarcoma, breast cancer, malignant histiocytoma, occult adenocarcinoma). The mutation found in her tumour and peripheral blood lymphocyte DNA is a cytosine to thymine transition at the second position of codon 278 resulting in an amino acid exchange from proline to leucine in the DNA-binding domain. Evaluation of the patient's family revealed that both of her sons were affected by the same mutation. Although the patient's mother had died already, we were able to demonstrate by polymorphic microsatellite analysis that the defective allele originated from the maternal side. As four brothers and one sister had inherited the same allele, which however was wild type, we were able to show that the mutation must have occurred in the germ cells of the patient's mother and that it may therefore be called de novo. This explains the lack of a high cancer incidence in the family history. All tumours tested showed positive immunohistochemical staining for p53. Loss of heterozygosity was found in five of seven tumours, one showing chromosome 17 monosomy. Images Figure 1 PMID:8688334

    Ovarian carcinoma is the most lethal gynecological malignancy among women and its poor prognosis is mainly due to metastasis. Chemokine receptor CCR9 is primarily expressed by a small subset of immune cells. The interactions between CCL25 and CCR9 have been implicated in leukocyte trafficking to the small bowel, a frequent metastatic site for ovarian cancer cells. We have previously shown that ovarian cancer cells express CCR9 and play an important role in cell migration, invasion and survival in the presence of its natural ligand in vitro. In this study, we have evaluated the expression of CCR9 and CCL25 in ovarian cancer cells and clinical samples. Ovarian cancer tissue microarrays from University of Alabama at Birmingham and AccuMax were stained for CCR9 and CCL25. Aperio ScanScope was used to acquire 80X digital images and expression analysis of CCR9 and CCL25. Flow cytometry and the Image stream system were used to conform the expression of CCR9 and CCL25 in ovarian cancer cells. Our results show significantly higher (p<0.001) expression of CCR9 and CCL25 in serous adenocarcinoma followed by serous papillary cystadenoma, endometrioid adenocarcinoma, mucinous adenocarcinoma, cystadenoma, mucinous boderline adenocarcinoma, clear cell carcinoma, granulosa cell tumor, dysgerminoma, transitional cell carcinoma, Brenner tumor, yolk sac tumor, adenocarcinoma and fibroma cases, compared to non-neoplastic ovarian tissue. Similar to tissue expression, CCR9 was also significantly expressed by the ovarian cancer cell lines (OVCAR-3 and SK-OV-3) in comparison to normal adult ovarian epithelial cell. We provide the first evidence that CCR9 and its natural ligand CCL25 are highly expressed by ovarian cancer tissue and their expression correlates with histological subtypes. Expression of this chemokine receptor and its ligand CCL25 within primary tumor tissue further suggests a potential role of this chemokine-receptor axis in ovarian cancer progression. PMID:21637913

    Nothing stirs the collective soul of primary debulking surgery (PDS) advocates like hard data suggesting equivalent outcomes of neoadjuvant chemotherapy (NAC). These opposing views have even metaphorically come to blows at the highly entertaining "SGO Fight Night" that took place during the 2008 Annual Meeting on Women's Cancer, replete with teams supporting each of the would-be gladiators. Decades of retrospective data supporting the clinical benefit of PDS has recently been challenged by the publication in 2010 of a randomized phase III trial conducted in Europe supporting the clinical efficacy of NAC. Naturally, a firestorm of criticism among believers ensued, yet practice patterns within the United States did slowly change, suggesting an emerging block of dissenters. Another randomized phase III European trial, as presented in abstract form in 2013, showed similar findings. Few other topics within the field of gynecologic oncology have participants so entrenched in the "corners" of their existing practice patterns. This review attempts to consolidate the current evidence supporting both sides so that the patient can be declared the winner. PMID:25316177

    Sleep loss places caregivers at risk for poor health. Understanding correlates of sleep loss and relationships to health may enable improvement of health of caregivers of individuals with primary malignant brain tumors (PMBT). In this cross-sectional, descriptive study of 133 caregivers, relationships were examined between sleep loss and physical, mental, emotional, and social health at time of patient diagnosis. Sleep loss was not related to physical health. Shorter total sleep time was associated with greater fatigue and social support. Sleep quality was positively associated with quality of life. Further study is needed of the role of sleep loss in the PMBT caregiving trajectory and its long-term relationship with health outcomes. PMID:23633116

    Primary malignant pericardial mesothelioma (PMPM) is a rare tumor with poor prognosis. Surgery is the treatment of choice, but numerous cases are inoperable. For the treatment of inoperable or metastatic cases, systemic chemotherapy is required. However, a standard chemotherapeutic regimen for the treatment of pericardial mesothelioma has not yet been established. Chemotherapy involving pemetrexed and cisplatin has been actively used in the treatment of pleural or peritoneal mesothelioma, and may be considered for the treatment of PMPM. The present study reports the case of a patient with PMPM with lung metastasis who demonstrated a positive response to treatment with pemetrexed and cisplatin followed by pemetrexed maintenance chemotherapy, leading to prolonged progression-free survival for 21 months.

    While ovarian cancer remains the most lethal gynecological malignancy in the United States, there are no biomarkers available that are able to predict therapeutic responses to ovarian malignancies. One major hurdle in the identification of useful biomarkers has been the ability to obtain enough ovarian cancer cells from primary tissues diagnosed in the early stages of serous carcinomas, the most deadly subtype of ovarian tumor. In order to detect ovarian cancer in a state of hyperproliferation, we analyzed the implications of molecular signaling cascades in the ovarian cancer cell line OVCAR3 in a temporal manner, using a mass-spectrometry-based proteomics approach. OVCAR3 cells were treated with EGF1, and the time course of cell progression was monitored based on Akt phosphorylation and growth dynamics. EGF-stimulated Akt phosphorylation was detected at 12 h post-treatment, but an effect on proliferation was not observed until 48 h post-exposure. Growth-stimulated cellular lysates were analyzed for protein profiles between treatment groups and across time points using iTRAQ labeling and mass spectrometry. The protein response to EGF treatment was identified via iTRAQ analysis in EGF-stimulated lysates relative to vehicle-treated specimens across the treatment time course. Validation studies were performed on one of the differentially regulated proteins, lysosomal-associated membrane protein 1 (LAMP-1), in human tissue lysates and ovarian tumor tissue sections. Further, tissue microarray analysis was performed to demarcate LAMP-1 expression across different stages of epithelial ovarian cancers. These data support the use of this approach for the efficient identification of tissue-based markers in tumor development related to specific signaling pathways. LAMP-1 is a promising biomarker for studies of the progression of EGF-stimulated ovarian cancers and might be useful in predicting treatment responses involving tyrosine kinase inhibitors or EGF receptor monoclonal

    Background. The aims of this study were to analyze the clinical characteristics of SPM in patients with well-differentiated thyroid cancer and to determine the long-term prognosis in patients with double malignancies. Materials and Methods. We retrospectively analyzed 2,864 patients with well-differentiated thyroid cancer and a mean age of 44.0 ± 14.4 years. Of these, 200 (7.0%) were diagnosed with SPM, 115 of which were diagnosed with metachronous SPM. Results. Of 2,864 patients, 163 (5.7%) patients died of thyroid cancer and 301 (10.5%) died of any cause by the end of the follow-up period. Multivariate analysis identified age, SPM, external radiotherapy, TNM stage, and postoperative serum Tg level to be factors independently associated with decreased survival. Of 200 patients with SPM, 74 (37.0%) died. In comparison to the anachronous and synchronous groups, the metachronous SPM group had a higher mean age; more advanced tumor, node, and metastasis stage; lower remission rate; higher postoperative radioactive iodide (131I) accumulated dose; a higher proportion of patients who underwent external radiotherapy; and higher thyroid cancer and total mortality rates. Conclusions. Patients with well-differentiated thyroid carcinoma and metachronous SPM had worse prognoses compared to patients without SPM. PMID:27118971

    Purpose Evolving therapies have improved the prognoses of patients with breast cancer; and currently, the number of long-term survivors is continuously increasing. However, these patients are at increased risk of developing a second cancer. Thus, late side effects are becoming an important issue. In this study, we aimed to investigate whether patient and tumor characteristics, and treatment type correlate with secondary tumor risk. Methods This case-control study included 305 patients with a diagnosed second malignancy after almost 6 months after the diagnosis of primary breast cancer and 1,525 controls (ratio 1:5 of cases to controls) from a population-based cohort of 6,325 women. The control patients were randomly selected from the cohort and matched to the cases according to age at diagnosis, calendar period of diagnosis, disease stage, and time of follow-up. Results BRCA1 or BRCA2 mutation, human epidermal growth factor receptor 2 (HER2)+ status, chemotherapy, and radiotherapy were related to increased risk of developing a second cancer, whereas hormonotherapy showed a protective effect. Chemotherapy, radiotherapy, and estrogenic receptor level <10% increased the risk of controlateral breast cancer. HER2+ status increased the risk of digestive system and thyroid tumors, while BRCA1 or BRCA2 mutation increased the risk of cancer in the genital system. Conclusion Breast cancer survivors are exposed to an excess of risk of developing a second primary cancer. The development of excess of malignancies may be related either to patient and tumor characteristics, such as BRCA1 or BRCA2 mutation and HER2+ status, or to treatments factors. PMID:26770245

    Background: To evaluate the advantages of contrast enhanced F-18-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-contrast enhanced CT [CECT]) when used as an initial imaging modality in patients presenting with metastatic malignancy of undefined primary origin (MUO). Materials and Methods: A total of 243 patients with fine needle aspiration cytology/biopsy proven MUO were included in this prospective study. Patients who were thoroughly evaluated for primary or primary tumor was detected by any other investigation were excluded from the analysis. Totally, 163 patients with pathological diagnosis of malignancy but no apparent sites of the primary tumor were finally selected for analysis. The site of probable primary malignancy suggested by PET-CECT was confirmed by biopsy/follow-up. Results: PET-CECT suggested probable site of primary in 128/163 (78.52%) patients. In 30/35 remaining patients, primary tumor was not detected even after extensive work-up. In 5 patients, where PET-CECT was negative, primary was found on further extensive investigations or follow-up. The sensitivity, specificity, positive predictive value and negative predictive value of the study were 95.76%, 66.67%, 88.28% and 85.71% respectively. Conclusions: F-18 FDG PET-CECT aptly serves the purpose of initial imaging modality owing to high sensitivity, negative and positive predictive value. PET-CECT not only surveys the whole body for the primary malignancy but also stages the disease accurately. Use of contrast improves the diagnostic utility of modality as well as help in staging of the primary tumor. Although benefits of using PET-CECT as initial diagnostic modality are obvious from this study, there is a need for a larger study comparing conventional methods for diagnosing primary in patients with MUO versus PET-CECT.

    Multiple primary malignancies (MPMs) are defined as 2 or more malignancies without subordinate relationship detected in different organs of an individual patient. Reports addressing MPM patients with hepatocellular carcinoma (HCC) are rare. We perform a 26-year follow-up study to investigate characteristics and prognosis of MPM patients associated with HCC due to the scarcity of relative researches.We retrospectively analyzed records of 40 patients who were diagnosed with MPM including HCC at the Departments of Surgery at Peking Union Medical College Hospital during 1989 to 2010. Their clinical characteristics and postoperative survival were compared with those of 448 patients who had HCC only during the study period.Among the 40 MPM patients, 11 were diagnosed synchronously and 29 metachronously. The most common extra-hepatic malignancies were lung cancer (15%), colorectal (12.5%), and thyroid carcinoma (12.5%). MPM patients had a negative hepatitis B virus infection rate (P = 0.013) and lower median alfa-fetoprotein (AFP) level (P = 0.001). Post-operative 1-, 3-, and 5-year overall survival (OS) rates for MPM patients were 82.5%, 64.5%, and 38.6% respectively, and showed no significant difference with those of HCC-only patients (84.7%, 54.2%, and 38.3% P = 0.726). During follow-up, 24 MPM patients died, including 17 (70.8%) who died of HCC-related causes. In univariate analysis, synchronous diagnosis, higher gamma glutamyltransferase (GGT) and/or AFP levels, tumor >5 cm and vascular invasion were significantly associated with shorter OS, but only tumor size was an independent OS factor in Cox modeling analysis.HCC should be considered as a potential second primary for all cancer survivors. Most MPM patients died of HCC-related causes and showed no significant difference in OS compared with HCC-only patients. Tumor size of HCC, rather than MPMs itself, was the only independent OS predictor for the MPM patients. PMID:27124050

    A primary melanocytic lesion arising from the pleura is a rare occurrence. This is the case report of a 36-year-old female patient with a primary pleural melanocytic tumor. The positron emission tomography/computed tomography scan revealed multiple nodular soft tissue thickenings of the left hemipleura and a large amount of pleural effusion in the left hemithorax. The results of the histological examination confirmed the diagnosis of melanoma. The disease progressed 4 months following immunotherapy and chemotherapy and the patient succumbed to the disease 2 months later. This type of tumor appears to exhibit a highly aggressive biological behavior and responds poorly to immunotherapy and chemotherapy, which are characteristics similar to those exhibited by melanomas arising in other regions.

    A twenty-five-year-old female presented with a large retroperitoneal mass. Workup included history and physical exam, imaging, biopsy, colonoscopy, and gynecologic exam. After surgical resection, the mass was determined to be a primary retroperitoneal mucinous tumor (PRMT). Clinically and histologically, these tumors are similar pancreatic and ovarian mucinous neoplasms. PRMTs are rare and few case reports have been published. PRMTs are divided into mucinous cystadenomas, mucinous borderline tumors of low malignant potential, and mucinous carcinoma. These tumors have malignant potential so resection is indicated and in some cases adjuvant chemotherapy and/or surveillance imaging. PMID:25874152

    Endometriosis is a chronic disease of women in the reproductive age, defined as endometrial cells growing outside of the uterine cavity and associated with relapses. Relapses are hypothesized to correlate with incomplete surgical excision or result from nonrandom implantation of new endometrial implants in adjacent peritoneum. Thus, surgical excision could lead to free endometriotic cells or tissue residues, which readhere, grow, and invade into recurrent lesions. Barrier agents are frequently used to prevent postoperative adhesions. We tested if the absorbable cell adhesion barrier gel Intercoat consisting of polyethylene oxide and sodium carboxymethyl cellulose could inhibit cellular adhesion, proliferation, and invasion of primary endometriosis and endometrial cells. Due to an association of endometriosis with ovarian carcinoma, we tested two ovarian carcinoma cell lines. Prior to cell seeding, a drop of the barrier gel was placed in cell culture wells in order to test inhibition of adherence and proliferation or coated over a polymerized collagen gel to assay for prevention of invasion. Results showed that the barrier gel significantly inhibited cell adherence, proliferation, and invasion of endometriosis and endometrial stromal cells as well as ovarian carcinoma cells in culture. Our findings could help to prevent local cell growth/invasion and possible consequent recurrences. PMID:25785270

    Objectives Vascular endothelial growth factors (VEGF) and their receptors have a critical role in stimulating the growth of ovarian cancer cells. Motesanib is a small molecule inhibitor of multiple receptor tyrosine kinases including VEGF receptors 1-3, as well as c-KIT and platelet-derived growth factor which are related to the VEGF family. Patients and Methods Twenty-two eligible patients with recurrent ovarian, fallopian tube or primary peritoneal carcinoma were treated with an oral daily dose of 125 mg of motesanib. Peripheral blood was analyzed for circulating tumor cells (CTC) and circulating endothelial cells/circulating endothelial progenitors (CEC/CEP), VEGF levels and cell-free circulating DNA (cfDNA). Results The study was abruptly halted after four patients developed posterior reversible encephalopathy syndrome. One patient had a partial response and seven patients had stable disease at the time they were removed from study treatment. Twelve of the 22 patients (50%) had indeterminate responses at trial closure. Early closure without clinical efficacy data precludes meaningful correlative studies. Conclusions The serious central nervous system toxicity observed in patients with recurrent ovarian cancer precluded full examination of this agent in this population. There were no clear cut explanations for the high incidence of this known class effect in the study population compared with patients with other cancers. PMID:23321064

    We report a rare case of primary pituitary lymphoma in a 75-year-old immunocompetent woman. The patient was blind in the right eye and presented with visual disturbance in the left eye that started 2 months previously. She also exhibited right third and fifth cranial nerve palsy. Magnetic resonance imaging(MRI)revealed an intrasellar mass lesion with right cavernous sinus invasion and suprasellar extension with compression of the optic chiasm. The mass lesion was isointense on both T1WI and T2WI, and showed less enhancement than a normal pituitary gland on gadolinium-enhanced T1WI. We therefore suspected the tumor to be a nonfunctioning pituitary adenoma. The patient underwent endoscopic endonasal transsphenoidal surgery. The tumor was firm and grayish, and had an ill-defined border along the normal pituitary gland. Histological examination revealed a malignant CD5-positive diffuse large B-cell lymphoma. After surgery, the patient received both chemotherapy and radiotherapy. Although the visual acuity of the right eye did not improved, other symptoms improved. At the 34-month follow-up, no recurrence was detected on serial MRI. Patients with primary pituitary lymphoma often exhibit ophthalmoplegia and/or panhypopituitarism more frequently than expected from radiological findings. In cases of pituitary tumors with atypical symptoms, a biopsy and general physical examination should be performed immediately to determine the diagnosis and perform adjuvant therapy even when the tumor is assumed as nonfunctioning pituitary adenoma from the image findings.

    Metastasis of colorectal adenocarcinoma of the ovary is not an uncommon occurrence and ovarian metastases from colorectal carcinoma frequently mimic endometrioid and mucinous primary ovarian carcinoma. The clinical and pathologic features of metastatic colorectal adenocarcinoma involving the ovary is reviewed with particular focus on the diagnostic challenge of distinguishing these secondary ovarian tumors from primary ovarian neoplasm. Immunohistochemical stains that may be useful in the differential diagnosis of metastatic colorectal tumors to the ovary and primary ovarian tumors are detailed. PMID:21160859

    The aim of this study was to investigate the expression of estrogen receptor (ER) beta and alpha genes in normal (N) and malignant (C) primary cultures of human prostate epithelial cells (PEC) and fibroblasts (PFC) and in the prostate tissue donors. Both ERbeta and ERalpha messenger ribonucleic acids were found by RT-PCR analysis in six NPECs and normal prostate tissues and in only one of six CPECs and in the respective cancer tissue donor. The other five CPECs and related cancer tissue donors and all normal and cancer PFCs expressed ERalpha messenger ribonucleic acid alone. Immunoblot analysis, using a polyclonal anti-ERbeta (C-terminal) antibody, demonstrated ERbeta protein in all NPEC lysates and in one of the six CPECS: ERalpha protein was expressed in both NPECs and CPECs when a polyclonal antibody directed against the ERalpha N-terminal domain was used. In contrast, ERalpha protein was not detected in two of the six CPEC lysates when ERalpha C-terminal monoclonal antibodies were used. Using a set of primers designed to amplify the region from exons 6-8, RT-PCR analysis demonstrated the absence of the expected transcript in these cells. The present study shows that the ERbeta gene is expressed together with ERalpha in normal prostates and NPECs, whereas it is barely detectable in prostate cancer and CPECS: Moreover, in some CPECs, the ERalpha gene may be transcribed in a changed protein, resulting from the expression of a deletion variant. Together, these data suggest that prostate malignancy is associated with a potential disorder of ER-mediated pathways. PMID:11344205

    In this communication, the authors summarize their characterization of eight ovarian adenocarcinoma-derived cell lines for level of neu gene amplification, expression of neu transcripts and protein, and intraperitoneal tumorigenicity in nude mice. Two of the eight cell lines in our study (SKOV3 and YAOVBIX1) exhibited five- to ninefold neu DNA sequence amplification, accompanied by up to 200-fold overexpression of transcripts and protein (p185). Both of these cell lines expressed a major approximately 7.5 kb neu-complementary transcript not previously reported in other neu-positive tumor cell lines. One pair of cell lines (YAOVBIX1 and YAOVBIX3), isolated from a single ovarian carcinoma patient's ascites sample differed dramatically in regard to level of neu gene amplification and expression. Immunohistochemical staining of the primary ovarian tumor from which these two lines were derived demonstrated populations of both neu-positive and neu-negative malignant epithelial cells. Seven of the eight ovarian carcinoma lines produced intra-abdominal tumors after intraperitoneal injection into nude mice, irrespective of level of neu gene expression. This study demonstrates tumor cell heterogeneity with regard to neu gene amplification and expression in an ovarian adenocarcinoma, reveals the overexpression of novel neu-complementary transcripts in two independently isolated ovarian adenocarcinoma cell lines, and suggests that neu gene expression is not required for intraperitoneal tumorigenicity of ovarian carcinoma xenografts in a nude mouse model system.

    Mucinous epithelial ovarian cancers (MOC) are clinically and morphologically distinct from the other histological subtypes of ovarian cancer. To determine the genetic basis of MOC and to identify potential tumour markers, gene expression profiling of 49 primary ovarian cancers of different histological subtypes was performed using a customised oligonucleotide microarray containing >59 000 probesets. The results show that MOC express a genetic profile that both differs and overlaps with other subtypes of epithelial ovarian cancer. Concordant with its histological phenotype, MOC express genes characteristic of mucinous carcinomas of varying epithelial origin, including intestinal carcinomas. Differences in gene expression between MOC and other histological subtypes of ovarian cancer were confirmed by RT–PCR and/or immunohistochemistry. In particular, galectin 4 (LGALS4) was highly and specifically expressed in MOC, but expressed at lower levels in benign mucinous cysts and borderline (atypical proliferative) tumours, supporting a malignant progression model of MOC. Hence LGALS4 may have application as an early and differential diagnostic marker of MOC. PMID:16508639

    Coexpression of epidermal growth factor receptor (EGFR) and c-erbB-2 in 47-68% of ovarian cancer cells indicate their strong association with tumor formation. We examined the effects of simultaneous antisense- or immunosuppression of EGFR and c-erbB-2 expression on the invasive phenotype, aneuploidy, and genotype of cultured human ovarian carcinoma cells (NIH:OVCAR-8). We report here that suppression of both EGFR and c-erbB-2 results in regression of aneuploidy and genomic imbalances in NIH:OVCAR-8 cells, restores a more normal phenotype, and results in a more normal gene expression profile. Combined with cytogenetic analysis, our data demonstrate that the regression of aneuploidy is due to the selective apoptosis of double antisense transfected cells with highly abnormal karyotype.

    A 42-year-old male patient was admitted to the Department of General Surgery of The First Affiliated Hospital of Henan University of Science and Technology (Luoyang, China) presenting with abdominal discomfort. Enhanced computed tomography of the abdomen revealed a 15.1×7.0-cm, enhanced, double-spherical, exogenous, solid tumor originating from the left lateral hepatic lobe, in addition to a 4.3×4.2-cm mass in the mid portion of the left kidney. Pre-operative imaging analysis resulted in the diagnosis of double cancer, consisting of hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC). The patient subsequently underwent left hemihepatectomy and left nephrectomy. Histological examination confirmed that the tumor originating from the left lateral hepatic lobe was HCC, and the tumor arising from the mid portion of the left kidney was clear cell RCC (ccRCC). The post-operative follow-up was uneventful. To the best of our knowledge, the present case is the first of its kind to describe the resection of synchronous double cancer, consisting of primary HCC and ccRCC. PMID:26998121

    Borderline ovarian tumours are low malignant potential tumours. They represent 10–15% of all epithelial ovarian malignancies. Patients with this type of tumour are younger at the time of diagnosis than patients with invasive ovarian cancer. Most of them are diagnosed in the early stages and have an excellent prognosis. It has been quite clearly established that the majority of borderline ovarian tumours should be managed with surgery alone. Because a high proportion of women with this malignancy are young and the prognosis is excellent, the preservation of fertility is an important issue in the management of these tumours. In this systemic review of the literature, we have evaluated in-depth oncological safety and reproductive outcomes in women with borderline ovarian tumours treated with fertility-sparing surgery, reviewing the indications, benefits, and disadvantages of each type of conservative surgery, as well as new alternative options to surgery to preserve fertility.

    Small GTPases, particularly the Rho family, are key regulators of cell motility and migration. Dock180 was well known for the main target of signal adaptor protein Crk and acted as a guanine-nucleotide exchange factor for small GTPase Rac1. In the present study, Dock180 was found to combine primarily with CrkI other than CrkII, and its association with Elmo1 was also demonstrated in ovarian cancer cell SKOV3. To evaluate the role of Dock180 in human ovarian cancer cell, we performed RNAi-mediated knockdown of Dock180 in SKOV3 cells using small interfering RNA expression vector. In Dock180 knockdown cells, we found that Elmo1 expression and Rac1 activity were decreased simultaneously. By contrast, the expressions of both another Crk-combining molecule C3G and Rap1 activity were observed to increase obviously. Accordingly, all Dock180 knockdown cells present with evident change in cell morphology, reduced cell proliferation, and attenuated cell migration. Taken together, these results suggest that signal transfer of Crk/Dock180/Rac1 is implicated in actin cytoskeleton reorganization and thus in the cell proliferation, motility, invasion, and of human ovarian cancer cell line SKOV3.

    Purpose: Using Reverse Phase Protein Array (RPPA) we measured protein expression associated with response to primary chemotherapy in patients with advanced-stage high-grade serous ovarian cancer. Experimental Design: Tumor samples were obtained from forty-five patients with advanced high-grade serous cancers from the Gynecology Tumor Bank at the British Columbia Cancer Agency. Treatment consisted of platinum-based chemotherapy following debulking surgery. Protein lysates were prepared from fresh frozen tumor samples and 80 validated proteins from signaling pathways implicated in ovarian carcinogenesis were measured by RPPA. Normalization of Ca-125 by the 3rd cycle of chemotherapy was chosen as the primary outcome measure of chemotherapy response. Logistic regression was used for multivariate analysis to identify protein predictors of Ca-125 normalization, and Cox regression to test for the association between protein expression and PFS. A significance level of p ≤ 0.05 was used. Results: The mean age at diagnosis was 56.8 years. EGFR, YKL-40 and several TGFβ pathway proteins (c-Jun N-terminal kinase JNK, JNK phosphorylated at residues 183 and 185, PAI-1, Smad3, TAZ) showed significant associations with Ca-125 normalization on univariate testing. On multivariate analysis, EGFR (p < 0.02), JNK (p < 0.01), and Smad3 (p < 0.04) were significantly associated with normalization of Ca-125. Contingency table analysis of pathway-classified proteins revealed that the selection of TGFβ pathway proteins was unlikely due to false discovery (p < 0.007, Bonferroni-adjusted). Conclusion: TGFβ pathway signaling likely plays an important role as a marker or mediator of chemoresistance in advanced serous ovarian cancer. On this basis, future studies to develop and validate a useful predictor of treatment failure are warranted. PMID:20460476

    Invasive aspergillosis (IA) is a life-threatening infection in severely immunocompromised haematological malignancy patients. In this study, the efficacy and safety of caspofungin, voriconazole or the combination as primary and salvage therapy in patients with IA were compared. The study included 181 patients with haematological malignancies and IA who received primary or salvage therapy with caspofungin, voriconazole or the combination. In total, 138 patients who received treatment for ≥7 days were analysed; 86 underwent primary antifungal therapy (15 with caspofungin, 38 with voriconazole and 33 with both). Among the salvage therapy patients, 17 received caspofungin, 24 received voriconazole and 35 received both. In the primary therapy group, no difference in therapy response was found, but caspofungin was associated with higher IA mortality rates. A multivariate competing risk analysis of primary antifungal therapy revealed that voriconazole was independently associated with lower IA-associated mortality rates than caspofungin (hazard ratio=0.2, 95% confidence interval 0.06-0.96; P=0.04). In the salvage therapy group, the three treatment groups had similar responses and IA-associated mortality rates. The combination of voriconazole and caspofungin did not result in better outcomes compared with voriconazole alone, as primary or salvage therapy, in haematological malignancy patients. However, voriconazole was associated with a lower Aspergillus-associated mortality rate compared with caspofungin monotherapy. PMID:25455847

    In the past two decades, more than 20 viruses with selective tropism for tumor cells have been developed as oncolytic viruses (OVs) for treatments of a variety of malignancies. Of these viruses, eleven have been tested in human ovarian cancer models in preclinical studies. So far, nine phase I or II clinical trials have been conducted or initiated using four different types of OVs in patients with recurrent ovarian cancers. In this article, we summarize the different OVs that are being assessed as therapeutics for ovarian cancer. We also present an overview of recent advances in identification of key genetic or immune-response pathways involved in tumorigenesis of ovarian cancer, which provides a better understanding of the tumor specificities and oncolytic properties of OVs. In addition, we discuss how next-generation OVs could be genetically modified or integrated into multimodality regimens to improve clinical outcomes based on recent advances in ovarian cancer biology.

    Advanced cases of epithelial ovarian, primary peritoneal, and primary tubal malignancies have a relatively poor prognosis and collectively remain the most deadly of all gynecologic malignancies. Although traditionally thought of as one disease process, ongoing research suggests that there is not 1 single site or cell type from which these cancers arise. A majority of the serous tumors appear to originate from dysplastic lesions in the distal fallopian tube. Therefore, what we have traditionally considered “ovarian” cancer may in fact be tubal in origin. In this article, we will review epithelial ovarian cancer classification and genetics, theories regarding cells of origin with a focus on tubal intraepithelial carcinoma, and implications for prevention and screening.

    The ovarian lymphoma is rare. Lymphoma presenting as an ovarian mass with initial manifestation is even rarer. We report a case of primary Non-Hodgkin’s Lymphoma (NHL) of left ovary in a 52-year-old female presented with distension of abdomen and lower abdominal back pain. USG and CT-scan imaging suggested provisional diagnosis of ovarian tumour. The diagnosis of malignant lymphoma was made by histopathological examination of the excised tissue along with immunohistochemistry by using LCA, CD20, cytokeratin & CD3. The tumour was classified as diffuse large B cell lymphoma. Rarity of this lesion warrants its mention. PMID:27437236

    Ovarian vein thrombosis (OVT) is a rare cause of abdominal pain that may mimic a surgical abdomen. It is most often diagnosed during the postpartum period. In this report, we present four cases of postoperative ovarian vein thrombosis. The complications of OVT can be significant, and the diagnosis relies on a careful examination of the radiographic findings. It can occur with lower quadrant abdominal pain, especially in the setting of recent pregnancy, abdominal surgery, pelvic inflammatory disease, or malignancy. Diagnosis can be made with confidence using ultrasound, computed tomography or magnetic resonance imaging. Treatment of ovarian vein thrombosis is particularly important in the post-partum patients, with anticoagulation therapy being the current recommendation. PMID:26526119

    Ovarian cancer is the most deadly gynecologic malignancy, with more than 15,000 deaths anticipated in 2012.1 While approximately 80% of patients will respond to frontline chemotherapy, more than 60% of patients will experience disease recurrence and only 44% will be alive at 5 years.1,2 Host anti-tumor immune responses are associated with a significant improvement in overall survival for women with ovarian cancer.3,4 By bolstering these responses, it may therefore be possible to significantly influence the prognosis of women with this lethal disease. In this review, we will focus on innovative immune-based strategies which are currently being investigated in the treatment of ovarian cancer. PMID:22906947

    Autophagy has been linked to the regulation of both the prevention and progression of cancer. IFN-γ has been shown to induce autophagy in multiple cell lines in vitro. However, whether IFN-γ can induce autophagy and whether autophagy promotes malignant transformation in healthy lactating bovine mammary epithelial cells (BMECs) remain unclear. Here, we provide the first evidence of the correlation between IFN-γ treatment, autophagy and malignant transformation and of the mechanism underlying IFN-γ-induced autophagy and subsequent malignant transformation in primary BMECs. IFN-γ levels were significantly increased in cattle that received normal long-term dietary corn straw (CS) roughage supplementation. In addition, an increase in autophagy was clearly observed in the BMECs from the mammary tissue of cows expressing high levels of IFN-γ. In vitro, autophagy was clearly induced in primary BMECs by IFN-γ within 24 h. This induced autophagy could subsequently promote dramatic primary BMEC transformation. Furthermore, we found that IFN-γ promoted arginine depletion, activated the general control nonderepressible-2 kinase (GCN2) signalling pathway and resulted in an increase in autophagic flux and the amount of autophagy in BMECs. Overall, our findings are the first to demonstrate that arginine depletion and kinase GCN2 expression mediate IFN-γ-induced autophagy that may promote malignant progression and that immunometabolism, autophagy and cancer are strongly correlated. These results suggest new directions and paths for preventing and treating breast cancer in relation to diet. PMID:27551491

    Background and Purpose Caregivers’ well-being has been found to be associated with marital adjustment. This study’s purpose was to evaluate the psychometric properties of the Locke-Wallace Short Marital-Adjustment Test (LWSMAT) in a sample of caregivers of persons with primary malignant brain tumor (PMBT). Methods Secondary analysis of data collected from 114 caregivers. The LWSMAT was tested for factor structure, internal consistency reliability, and construct validity. Results 5 extracted factors explained 60.55% of the total variance. Four interpretable factors (Contentment & Communication, Leisure & Sociality, Intimacy, and Shared Philosophy) had Cronbach’s alpha between 0.63 and 0.74. Convergent validity (r = −.35 and r = −.43, respectively, both p < .0001) and discriminant validity (r = .07, p = .49; and r = −.04, p = .67) were confirmed by comparing four factors with subdimensions of the Caregiver Reaction Assessment (CRA). Conclusion The LWSMAT is a multidimensional, reliable, and valid measure of marital adjustment in caregivers of persons with a PMBT. PMID:24620520

    AIM To determine the risk of second primary malignancy (SPM) and survival of patients with essential thrombocythemia (ET). METHODS We identified all patients with ET diagnosed during 2001 to 2011 from the Surveillance, Epidemiology and End Results (SEER) 18 database. Actuarial and relative survival methods were used to calculate the survival statistics. We utilized the SEER 13 database to calculate SPM. We used multiple primary standardized incidence ratio (SIR) session of the SEER*Stat software (version 8.1.5) to calculate SIR and excess risk of SPM for ET patients. RESULTS Age standardized five-year cause-specific survival was greater for patients < 50 years vs those ≥ 50 years (99.4% vs 93.5%, P < 0.01). Five-year cause-specific survival was lower for men vs women (70.2% vs 79.7%). A total of 201 patients (2.46%) developed SPM at a median age of 75 years. SPMs occurred at an observed/expected (O/E) ratio of 1.26 (95%CI: 1.09-1.45, P = 0.002) with an absolute excess risk (AER) of 37.44 per 10000 population. A significantly higher risk was noted for leukemia (O/E 3.78; 95%CI: 2.20-6.05, P < 0.001; AER 11.28/10000). CONCLUSION ET patients have an excellent cause-specific five-year survival but are at an increased risk of SPM, particularly leukemia, which may contribute to excess deaths. PMID:27579252

    Malignant ovarian neoplasms diagnosed during pregnancy at advanced stages are very rare. The clinical course and prognosis of pregnant patients diagnosed with epithelial ovarian cancer is similar to that of non-pregnant patients. We describe our management of a woman diagnosed with FIGO IIIc ovarian cancer at Caesarean section. Immediately after surgery she suffered a pulmonary embolus and a myocardial infarction. She showed signs of a severe pulmonary hypertension (59 mmHg). Four weeks later the pulmonary hypertension was still moderate but, despite her critical status, she underwent primary debulking surgery (PDS). This was performed under extensive anaesthesiological monitoring. Through this rare case, we show that despite the complex initial status of a critically ill patient, PDS can still remain the mainstay of treatment in patients with advanced ovarian cancer as most patients are able to tolerate even extensive debulking surgery without the need for neoadjuvant chemotherapy.

    Malignant transformation of a mature cystic teratoma (MCT) is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a), mucinous adenocarcinoma (b), and strumal carcinoid tumor (c)—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a). Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b). Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c). PMID:23029627

    2015-01-01

    Introduction: The long-term sequelae of radioactive iodine (RAI) for differentiated thyroid cancer (DTC) in pediatric and young adult patients are not well-defined. Epidemiologic analyses of second primary malignancy (SPM) risk have only been performed in the adult population. Existing data are limited to case series with limited follow-up. The objective of this study was to analyze the elevated risk of SPM attributable to RAI in young patients treated for DTC. Methods: Population-based analysis of 3850 pediatric and young adult patients (<25 years old) undergoing treatment with surgery with/without RAI for DTC, followed in the Surveillance, Epidemiology, and End Results cancer registry (1973–2008), equating to 54,727 person-years at risk (PYR). The excess risk of SPM was calculated relative to a reference population and expressed as standardized incidence ratio (SIR) and excess absolute risk (EAR) per 10,000 PYR. Excess risk was compared in RAI-treated and non-RAI-treated patients. Results: A total of 1571 patients (40%) received RAI. The percentage of patients treated with RAI increased over time, from 4% in 1973 to 62% in 2008 (p<0.001). Among patients who received RAI, 26 SPMs were observed, and 18.3 were expected. The relative risk of SPM at any site was significantly elevated (SIR=1.42), corresponding to 4.4 excess cases per 10,000 PYR. SPM risk was not elevated in the non-RAI-treated cohort (SIR=1.01, EAR=0). Patients treated with RAI were at dramatically elevated risk for development of a salivary malignancy (SIR=34.1), corresponding to 1.7 excess cases per 10,000 PYR. The risk of leukemia in RAI-treated patients was elevated (SIR=4.0, EAR=0.9) but did not reach statistical significance. There was no elevated risk of salivary cancer or leukemia in the non-RAI-treated cohort. Conclusions: Pediatric and young adult patients who receive RAI for DTC experience an elevated risk of SPM, mainly salivary gland cancer. These risks appear to be only slightly higher

    PubMed Central

    2012-01-01

    Purpose The aim of this systematic review was to systematically assess the potential patient-relevant benefit (primary aim) and diagnostic and prognostic accuracy (secondary aim) of positron emission tomography (PET) and PET/computed tomography (CT) in primary staging of malignant melanoma. This systematic review updates the previous evidence for PET(/CT) in malignant melanoma. Materials and methods For the first aim, randomized controlled trials (RCTs) investigating patient-relevant outcomes and comparing PET and PET(/CT) with each other or with conventional imaging were considered. For the secondary aim, a review of reviews was conducted, which was amended by an update search for primary studies. MEDLINE, EMBASE and four databases of the Cochrane Library were searched. The risk of bias was assessed using a modified QUADAS tool. Results No RCTs investigating the patient-relevant benefit of PET(/CT) and no prognostic accuracy studies were found. Seventeen diagnostic accuracy studies of varying quality were identified. For patients with American Joint Committee on Cancer (AJCC) stages I and II, sensitivity mostly ranged from 0 to 67%. Specificity ranged from 77 to 100%. For AJCC stages III and IV, sensitivity ranged from 68 to 87% and specificity from 92 to 98%. Conclusion There is currently no evidence of a patient-relevant benefit of PET(/CT) in the primary staging of malignant melanoma. RCTs investigating patient-relevant outcomes are therefore required. The diagnostic accuracy of PET(/CT) appears to increase with higher AJCC stages. PMID:23237499

    Objective To assess the ability of the Age-Adjusted Charlson Comorbidity index (ACCI) to predict perioperative complications and survival in patients undergoing primary debulking for advanced epithelial ovarian cancer (EOC). Methods Data were analyzed for all patients with stage IIIB-IV EOC who underwent primary cytoreduction from 1/2001–1/2010 at our institution. Patients were divided into 3 groups based on an ACCI of 0–1, 2–3, and ≥4. Clinical and survival outcomes were assessed and compared. Results We identified 567 patients; 199 (35%) had an ACCI of 0–1, 271 (48%) had an ACCI of 2–3, and 97 (17%) had an ACCI of ≥4. The ACCI was significantly associated with the rate of complete gross resection (0–1=44%, 2–3=32%, and ≥4=32%; p=0.02), but was not associated with the rate of minor (47% vs 47% vs 43%, p=0.84) or major (18% vs 19% vs 16%, p=0.8) complications. The ACCI was also significantly associated with progression-free (PFS) and overall survival (OS). Median PFS for patients with an ACCI of 0–1, 2–3, and ≥4 was 20.3, 16, and 15.4 months, respectively (p=0.02). Median OS for patients with an ACCI of 0–1, 2–3, and ≥4 was 65.3, 49.9, and 42.3 months, respectively (p<0.001). On multivariate analysis, the ACCI remained a significant prognostic factor for both PFS (p=0.02) and OS (p<0.001). Conclusions The ACCI was not associated with perioperative complications in patients undergoing primary cytoreduction for advanced EOC, but was a significant predictor of PFS and OS. Prospective clinical trials in ovarian cancer should consider stratifying for an age-comorbidity covariate. PMID:26037900

    Objective The XIST gene is considered to be an attractive candidate gene for skewed X-chromosome inactivation and a possible cause of primary ovarian insufficiency (POI). The purpose of this study was to investigate whether the XIST gene promoter mutation is associated with idiopathic POI in a sample of the Korean population. Methods Subjects consisted of 102 idiopathic POI patients and 113 healthy controls with normal menstrual cycles. Patients with the following known causes of POI were excluded in advance: cytogenetic abnormalities, prior chemo- or radiotherapy, or prior bilateral oophorectomy. Genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism analysis. Results The mean age of onset of ovarian insufficiency was 28.7±8.5 years and the mean values of serum luteinizing and follicle-stimulating hormones and estradiol in the POI group were 31.4±18.2 mIU/mL, 74.5±41.1 mIU/mL, and 30.5±36.7 pg/mL, respectively. We found no cytosine to guanine (C43G) variation in the XIST gene in both POI patients and controls. Conclusion The C43G mutation in the promoter region of the XIST gene was not present in the Korean patients with idiopathic POI in our study, in contrast to our expectation, suggesting that the role of XIST in the pathogenesis of POI is not yet clear.

    Ovarian carcinoma is the leading cause of death from gynecologic malignancies. The oncogenic role of anaplastic lymphoma kinase (ALK) is well characterized in many hematopoietic and solid tumors. ALK expression in ovarian carcinoma has been reported but the exact status of ALK protein and its association with clinicopathologic features requires further investigation. ALK expression was determined by immunohistochemistry in 110 primary ovarian carcinomas, including 85 cases of serous carcinoma and 25 cases of mucinous carcinoma. Fluorescence in situ hybridization (FISH) and real-time reverse transcription polymerase chain reaction (RT-PCR) were used for evaluating ALK translocation in ALK-positive ovarian carcinomas. Among 110 ovarian carcinomas, 23 (20.9%) cases were ALK positive by immunohistochemistry. All ALK-positive cases were ovarian high-grade serous carcinoma. ALK expression was detected in 23/85 (27.1%) ovarian serous carcinoma and 0/25 (0%) in ovarian mucinous carcinoma. None of the 23 ALK IHC-positive cases harbored ALK gene translocations by FISH or RT-PCR. ALK protein expression was associated with patient age, tumor stage, and histologic type. Specifically, the probability of ALK protein expression was significantly higher in high-grade serous carcinomas in older patients (above 50 y) with advanced disease (FIGO stage III and IV) compared with the low-grade serous and mucinous carcinomas in younger patients with relatively early disease. In conclusion, aberrant ALK expression is observed in ovarian serous carcinoma but not in mucinous carcinoma, is independent of gene translocation, and might be associated with progression and prognosis.

    Context: Women with primary ovarian insufficiency have significantly lower serum estradiol and T levels compared with regularly menstruating women. They also have significantly reduced bone mineral density (BMD). Objective: The objective of the study was to evaluate the efficacy of hormone replacement in maintaining BMD in these young women. Design and Setting: This was a randomized, double-blind, single-center, placebo-controlled clinical trial at the National Institutes of Health clinical center (Bethesda, Maryland). Participants: Young women with primary ovarian insufficiency participated in the study. Interventions: We compared the effect of estradiol and progestin replacement (n = 72) vs estradiol, progestin, and T replacement (n = 73) on BMD. We also compared findings with a contemporaneous control group of normal women (n = 70). All patients received transdermal estradiol (100 μg/d) plus oral medroxyprogesterone acetate 10 mg/d (12 d/mo) for a 3-month run-in period before being randomized in a double-blinded fashion to the addition of transdermal T (150 μg/d) or placebo. Main Outcome Measure: Change in BMD at the femoral neck was measured by dual-energy x-ray absorptiometry. Results: At screening, patients had significantly lower femoral neck BMD compared with control women (0.77 vs 0.81 g/cm2, P = .001) and did not differ in body mass index, age at menarche, or education level. Normal control women lost femoral neck BMD over the study period, whereas patients on estradiol and progestin therapy gained BMD; and at the end of the study period, femoral neck BMD of patients on estradiol and progestin therapy did not differ from that of control women (0.80 g/cm2 in both groups, P = .9). The addition of T showed no further benefit (percentage change in BMD 3.9 vs 2.4, respectively, P = .9). Nonetheless, using a repeated-measures model, the T group achieved a mean BMD in the femoral neck 0.015 g/cm2 higher than the placebo group at 3 years (95% confidence

    Malign melanoma of the nasal cavity that arises at such an unusual location is an exceptional case only occasionally mentioned in the literature. An amelanotic form, which is an uncommon type for this malignancy, also has an unusual radiological appearence from the classic melanotic form. We report here the magnetic resonance imaging (MRI) findings of a 46-year-old man who had a nasal cavity mass diagnosed as an amelanotic malign melanoma and discuss the importance of differential diagnosis with such an unusual radiological manifestation in this location.

    Background: Childhood ovarian neoplasms are very rare. Little information is available on the relative pattern and frequency of these tumors in Nigerian children. Earlier study done in Ibadan involved ovarian neoplasms in children and adolescents. The aim of this study is to review cases of ovarian neoplasms in children <15 years over a 22½ years period. Materials and Methods: This was a retrospective study. Twenty-four cases of childhood ovarian neoplasms were seen in patients <15 years of age. These cases were classified using the current World Health Organization histological classification of ovarian tumors. Results: Childhood ovarian neoplasms accounted for 2.8% of all cases of ovarian tumors seen in this period. Fourteen (58.3%) cases of childhood ovarian neoplasms were benign, and 10 (41.7%) were malignant. Mature cystic teratoma occurring in 13 (54.2%) was the most common childhood ovarian neoplasm and was most prevalent between 10 and 14 years of age. Burkitt lymphoma was the most common 4 (40%) malignant childhood ovarian tumor and prevalent between 5 and 14 years of age. Conclusion: Mature cystic teratoma remains the single most common childhood ovarian neoplasms, and Burkitt's lymphoma is the most malignant childhood ovarian tumor in Ibadan, South-western Nigeria.

    In the present study we examined prognostic value of immunohistochemical estimation of topoisomerase 1A (TOP 1A) and HER-2/neu expression in ovarian cancers treated with platinum-based drugs but not with topotecan and the relation between expression of these proteins on the one hand and intensity of proliferation (Ki67) on the other. The analyses were performed on 73 samples of ovarian carcinoma originating from 43 first-look laparotomies (FLL) and, in 30 cases, from secondary cytoreductions (SCR)(after chemotherapy) from the same patients. In paraffin sections immunohistochemical reactions were performed using antibodies directed to HER-2/neu, TOP 1A and Ki67. Kaplan-Meier's analysis disclosed a shorter overall survival time in cases with augmented expression of TOP 1A at FLL and with higher expression of Ki67 at SCR. A shorter progression-free time was detected in cases with higher proportion of Ki67 positive cells at FLL. No relationship could be disclosed between HER-2/neu expression and the studied clinicopathological parameters. The studies confirmed high value of Ki67 estimation. The augmented expression of TOP 1A was demonstrated to represent an unfavourable prognostic factor. Thus, in cases with elevated expression of TOP 1A application of topotecan-based therapeutic schemes should be considered. PMID:16598670

    The safety and maximum tolerated dose (MTD) of erlotinib with docetaxel/carboplatin were assessed in patients with ovarian cancer. Chemonaive patients received intravenous docetaxel (75 mg m−2) and carboplatin (area under the curve 5) on day 1 of a 3-week cycle, and oral erlotinib at 50 (cohort 1), 100 (cohort 2a) or 75 mg day−1 (cohort 2b) for up to six cycles. Dose-limiting toxicities were determined in cycle 1. Forty-five patients (median age 59 years) received treatment. Dose-limiting toxicities occurred in 1/5/5 patients (cohorts 1/2a/2b). The MTD of erlotinib in this regimen was determined to be 75 mg day−1 (cohort 2b; the erlotinib dose was escalated to 100 mg day−1 in 11 out of 19 patients from cycle 2 onwards). Neutropaenia was the predominant grade 3/4 haematological toxicity (85/100/95% respectively). Common non-haematological toxicities were diarrhoea, fatigue, nausea and rash. There were five complete and seven partial responses in 23 evaluable patients (52% response rate). Docetaxel/carboplatin had no measurable effect on erlotinib pharmacokinetics. In subsequent single-agent maintenance, erlotinib was given at 100–150 mg day−1, with manageable toxicity, until tumour progression. Further investigation of erlotinib in epithelial ovarian carcinoma may be warranted, particularly as maintenance therapy. PMID:18506181

    Introduction. Uterine leiomyoma is the most common benign pathology in women and lipoleiomyoma is an extremely rare and specific type of leiomyoma. Here, we report an unusual case of giant pedunculated subserous lipoleiomyoma misdiagnosed preoperatively as leiomyosarcoma. Case. A 45-year-old woman admitted to our gynecology outpatient clinic for complaints of abdominal distention, tiredness, and pelvic pain for the last 6 months. Sonography and abdominal magnetic resonance imaging (MRI) showed a giant semisolid mass that filled whole abdominal cavity from pelvis to subdiaphragmatic area. A primary diagnosis of uterine sarcoma or ovarian malignancy was made. On operation, total abdominal hysterectomy with a pedunculated mass of size 30 × 23 × 12 cm and weighing 5.4 kg and bilateral salpingo-oophorectomy were performed. The histopathology revealed a lipoleiomyoma with extensive cystic and fatty degeneration without any malignancy. Discussion. The diagnosis of leiomyoma is done usually with pelvic ultrasound but sometimes it is difficult to reach a correct diagnosis especially in cases of giant and pedunculated lipoleiomyoma that included fatty tissue which may mimick malignancy. Conclusion. Subserous pedunculated giant lipoleiomyoma should be kept in mind in the differential diagnosis of leiomyosarcoma or ovarian malignancy. PMID:26266066

    Hydrogel-encapsulating culture systems for ovarian follicles support the in vitro growth of secondary follicles from various species including mouse, non-primate human, and human; however, the growth of early stage follicles (primary and primordial) has been limited. While encapsulation maintains the structure of early stage follicles, feeder cell populations, such as mouse embryonic fibroblasts (MEFs), are required to stimulate growth and development. Hence, in this report, we investigated feeder-free culture environments for early stage follicle development. Mouse ovarian follicles were encapsulated within alginate hydrogels and cultured in various growth medium formulations. Initial studies employed embryonic stem cell medium formulations as a tool to identify factors that influence the survival, growth, and meiotic competence of early stage follicles. The medium formulation that maximized survival and growth was identified as αMEM/F12 supplemented with fetuin, insulin, transferrin, selenium, and follicle stimulating hormone (FSH). This medium stimulated the growth of late primary (average initial diameter of 80 µm) and early secondary (average initial diameter of 90 µm) follicles, which developed antral cavities and increased to terminal diameters exceeding 300 µm in 14 days. Survival ranged from 18% for 80 µm follicles to 36% for 90 µm follicles. Furthermore, 80% of the oocytes from surviving follicles with an initial diameter of 90–100 µm underwent germinal vesicle breakdown (GVBD), and the percentage of metaphase II (MII) eggs was 50%. Follicle/oocyte growth and GVBD/MII rates were not significantly different from MEF co-culture. Survival was reduced relative to MEF co-culture, yet substantially increased relative to the control medium that had been previously used for secondary follicles. Continued development of culture medium could enable mechanistic studies of early stage folliculogenesis and emerging strategies for fertility preservation. PMID

    Purpose Intraperitoneal chemotherapy has shown a survival advantage over intravenous chemotherapy for women with newly diagnosed optimally debulked epithelial ovarian, fallopian tube, or primary peritoneal carcinoma. However, significant toxicity has limited its acceptance. In an effort to reduce toxicity, the Gynecologic Oncology Group conducted a Phase I study to evaluate the feasibility of day 1 intravenous (IV) paclitaxel and intraperitoneal (IP) cisplatin followed by day 8 IP paclitaxel on an every 21-day cycle. Methods Patients with Stage IIB-IV epithelial ovarian, fallopian tube, primary peritoneal carcinomas or carcinosarcoma received paclitaxel 135 mg/m2 IV over 3 hours followed by cisplatin 75 mg/m2 IP on day 1 and paclitaxel 60 mg/m2 IP on day 8 of a 21 day cycle with 6 cycles planned. Dose-limiting toxicity (DLT) was defined as febrile neutropenia or dose-delay of greater than 2 weeks due to failure to recover counts, or Grade 3-5 non-hematologic toxicity occurring within the first 4 cycles of treatment. Results Twenty of 23 patients enrolled were evaluable and nineteen (95%) completed all six cycles of therapy. Three patients experienced a DLT consisting of infection with normal absolute neutrophil count, grade 3 hyperglycemia, and grade 4 abdominal pain. Conclusions This modified IP regimen which administers both IV paclitaxel and IP cisplatin on day one, followed by IP paclitaxel on day eight, of a twenty-one day cycle appears feasible and is an attractive alternative to the intraperitoneal treatment regimen administered in GOG-0172.

    Ovarian cancer is the leading cause of death from gynecologic malignancies. Reasons for the high mortality rate associated with ovarian cancer include a late diagnosis at which time the cancer has metastasized throughout the peritoneal cavity. Cancer metastasis is facilitated by the remodeling of the extracellular tumor matrix by a family of proteolytic enzymes known as the matrix metalloproteinases (MMPs). There are 23 members in the MMP family, many of which have been reported to be associated with ovarian cancer. In the current paradigm, ovarian tumor cells and the surrounding stromal cells stimulate the synthesis and/or activation of various MMPs to aid in tumor growth, invasion, and eventual metastasis. This review sheds light on the different MMPs in the various types of ovarian cancer and their impact on the progression of this gynecologic malignancy. PMID:25918438

    Acute abdomen is a challenge to first-line physicians because of frequently missed diagnoses and potential follow-on legal problems. Improving the management of these patients is of paramount importance, not only for saving lives, but also for reducing untoward problems associated with improper management. We present a case of a patient with acute abdomen due to intraperitoneal hemorrhage secondary to rupture of an ovarian tumor. Following emergency surgery, the patient was diagnosed with metastatic ovarian carcinoma. Because of improper preparation of the gastrointestinal tract, the patient underwent repeat exploratory laparotomy for colon carcinoma. Although this situation did not affect the outcome of the patient in this case, we are concerned that the patient did not benefit from a single operation, with primary complete excision of the tumor plus a colostomy. The outcome of patients with pelvic malignancy, especially those with ovarian carcinoma, might be better if initial surgery achieved optimal tumor debulking. This is possible with good preoperative planning and preparation. We emphasize the importance of preoperative preparation in spite of urgently needed care. Furthermore, every first-line physician should communicate the possibility of malignancy to patients and their families. PMID:10746423

    We present a rare case of malignant rhabdoid tumor (ovarian small cell carcinoma of hypercalcemic type) in a 24-year-old female with fulminant course. Clinically, hypercalcemia was not found at the time of primary diagnosis. However, it appeared later during the course of tumor progression. Histologically, the tumor showed classical features of small cell carcinoma of hypercalcemic type. Therapy included radical surgery with adjuvant chemotherapy. Despite this intensive therapy, the disease recurred and the patient died 10 months after the diagnosis. We discuss the diagnosis and therapy of this tumor, as well as its recent classification as malignant rhabdoid tumor. PMID:27462229

    Synchronous bilateral primary breast malignant phyllodes tumor or/and carcinoma of the breast with Paget’s disease is rare. In the article, we present a case of bilateral carcinoma of the breast with Paget’s disease of the right breast and malignant phyllodes tumor of the left breast. A 44-years-old Chinese woman presented with a 1 month history of the right breast nipple with eczema and fester and growing and palpable mass of left breast. Molybdenum target X-ray revealed microcalcification in the right breast, which was highly suspected of malignant tumor, and round-like mass with smooth surface and homogeneous density in the left breast. Color ultrasound showed a lobulated lump which circumferential blood flows around in the left breast, and which did not show any mass in the right breast. The patient was undertaken the bilateral modified radical mastectomy. The histological diagnosis was Paget’s disease associated with infiltrating ductal carcinoma in the right breast and malignant phyllodes tumor the left breast. The patient also received 6 cycles of the postoperative adjuvant chemotherapy by using T.T. regimen comprised docetaxel (100 mg) and pirarubicin (60 mg). PMID:26770378

    Some bioactive peptides derived from natural resources or synthesized by rational design have been proved to have very good anticancer effect. We studied the inhibition of PGPIPN, a hexapeptide derived from bovine β-casein, on the invasion and metastasis of human ovarian cancer cells in vitro and its molecular mechanism. The human ovarian cancer cells studied include the cell line SKOV3 as well as the primary ovarian cancer cells from ovarian tumor tissues of 37 patients at initial debulking surgery, diagnosed as serous ovarian adenocarcinoma. We showed that PGPIPN inhibited the invasion of ovarian cancer cells with Transwell chamber assay, the migration of ovarian cancer cells with cell scratch assay and colony formation of ovarian cancer cells. The expression (mRNAs and proteins) of genes relevant to invasion and metastasis, MTA1, and NM23H1 were analyzed by real-time PCR and western blotting. PGPIPN repressed the expression of MTA1, and promoted NM23H1. The effects of PGPIPN were dose-dependent. Thus, our study suggests that PGPIPN is a potential therapeutic agent for adjuvant therapy of human malignant ovarian tumors. PMID:26893013

    Purpose: To examine the risk of subsequent primary malignancies (SPMs) in women diagnosed with endometrial cancer. Methods and Materials: The National Cancer Institute's Survival, Epidemiology, and End Results database was used to determine the risk of SPM after endometrial cancer in 69,739 women diagnosed between 1973 and 2005. Standardized incidence ratios were calculated (observed/expected [O/E]) for SPM sites. Results: Median follow-up was 11.2 years, representing 757,567 person-years of follow-up. The risk of SPM was significantly increased for small intestine (O/E = 1.48; 99% confidence interval [CI], 1.03-2.05), colon (O/E = 1.16; CI, 1.09-1.24), vagina (O/E = 2.71; CI, 1.86-3.8), and urinary bladder (O/E = 1.41; CI, 1.25-1.59) SPMs and decreased for oral cavity and pharynx (O/E = 0.75; CI, 0.6-0.93), lung and bronchus (O/E = 0.78; CI, 0.72-0.84), and esophagus (O/E = 0.58; CI, 0.37-0.86) SPMs. Patients receiving external-beam radiotherapy for endometrial cancer had an increased risk of colon (p < 0.001), bladder (p < 0.001), vagina (p = 0.04), and soft-tissue (p = 0.014) SPMs. Patients treated with brachytherapy had an increased risk of bladder SPM (p = 0.006). A positive bidirectional association with endometrial cancer was observed for colorectal cancer, with a negative bidirectional association for oropharyngeal and lung cancers. Conclusions: Genetic, environmental, and treatment-related factors influence SPM risk. Genetic factors may contribute to the increased risk of colorectal cancer. Smoking's negative effect on endometrial cancer risk factors might explain the decreased risk of lung and oropharyngeal cancer. Patients treated with radiotherapy likely have a small but significantly increased risk of bladder, vagina, colon, and soft-tissue SPM.

    Epithelial ovarian carcinoma is the deadliest gynecologic malignancy. One reason underlying treatment failure is resistance to paclitaxel. Expression of the microtubule associated protein tau has recently been proposed as a predictor of response to paclitaxel in ovarian carcinoma patients. Expression of tau was probed using immunohistochemistry in 312 specimens of primary, and 40 specimens of metastatic, ovarian carcinoma. Serous epithelial ovarian carcinoma cell line models were used to determine the expression of tau by Western blot and immunofluorescence staining. Subcellular fractionation and Western blot were employed to examine nuclear and cytoplasmic localization of tau. Gene silencing and clonogenic assays were used to evaluate paclitaxel response. Tau was expressed in 44% of all tested cases. Among the primary serous epithelial ovarian carcinoma cases, 46% were tau-positive. Among the metastatic serous epithelial ovarian carcinomas, 63% were tau-positive. Cell culture experiments demonstrated that tau was expressed in multiple isoforms. Three-dimensional collagen I matrix culture conditions resulted in up-regulation of tau protein. Silencing of tau with specific siRNAs in a combination with three-dimensional culture conditions led to a significant decrease of the clonogenic ability of cells treated with paclitaxel. The data suggest that reduction of tau expression may sensitize ovarian carcinoma to the paclitaxel treatment. PMID:25658796

    Lymph node histology and staging with cross sectional imaging remains basis for the treatment planning in primary malignant lymphoma. Contrast enhanced computed tomography is considered to be gold standard. However, MRI is equally able to provide staging and follow up in the same quality as helical CT, as several studies and clinical experience show. MRI is considered as the superior imaging modality for extranodal lymphoma. Advantages of MRI are that it works without ionizing radiation and contrast media;however, MRI is more expensive and time consuming. However, both imaging modalities are limited by the fact that the differentiation of affected and non affected lymph nodes is based on size only. Also the results of recent clinical studies with USPIOs (SINEREM((R):)) for intravenous MR lymphography in primary malignant lymphoma do not look promising. Despite these disadvantages of MRI, for young patients with malignant lymphoma radiation protection should be taken into account because of frequent imaging in staging and follow up. PMID:12486553

    Ovarian carcinomas are a heterogeneous group of neoplasms traditionally sub-classified based on type and degree of differentiation. Although current clinical management of ovarian carcinoma largely fails to take this heterogeneity into account, it is becoming evident that each major histological type has characteristic genetic defects that deregulate specific signaling pathways in the tumor cells. Moreover, within the most common histological types, the molecular pathogenesis of low-grade versus high-grade tumors appears to be largely distinct. Mouse models of ovarian carcinoma have been developed that recapitulate many of the morphological features, biological behavior, and gene expression patterns of selected subtypes of ovarian cancer. Such models will likely prove useful for studying ovarian cancer biology and for pre-clinical testing of molecularly targeted therapeutics, which may ultimately lead to better clinical outcomes for women with ovarian cancer.

    A thorough laparoscopic assessment of the abdominopelvic cavity is a crucial step in the workup of primary advanced epithelial ovarian cancer to decide whether up-front cytoreductive surgery or neoadjuvant chemotherapy is the best option for adequate management. The purpose of our study was to compare single-port laparoscopy (SPL), classic laparoscopy (CL), and laparotomy using the peritoneal cancer index (PCI). Patients treated for Fédération Internationale de Gynécologie et d'Obstétrique stage 3 or 4 epithelial ovarian cancer were included in our study when they underwent a PCI evaluation by laparoscopy followed by laparotomy for cytoreduction. According to the technique used for the "noninvasive" procedure (SPL vs CL), 2 groups were compared retrospectively. The individual records of all patients were reviewed and analyzed. From 2011 to 2014, 21 patients were assessed for PCI by SPL plus laparotomy versus 21 by CL plus laparotomy. The clinicopathological features were similar in both groups (not significant [NS]), except for performance status >0, which was more frequent in the SPL group (39% vs 6%, p = .04). Quotation of PCI was possible for all patients. Nonbrowsing areas marked 3 procedures in the SPL group and 2 procedures in the CL group (NS). The mean PCI score and the score of each region assessed by SPL and CL were comparable with the evaluation by laparotomy (NS). Completeness of cytoreduction was achieved in 78% of cases in both groups (NS). SPL and widely mini-invasive procedures seem to be effective tools compared with laparotomy to adequately assess the resectability of a peritoneal carcinomatosis using the PCI. PMID:27068278

    Objectives To examine the cost-effectiveness of primary debulking surgery (PDS) when compared to neoadjuvant chemotherapy (NACT) in the management of epithelial ovarian cancer (EOC) using Surveillance, Epidemiology, and End Results data linked to Medicare claims (SEER-Medicare). Methods Using a Markov model, the cost-effectiveness of PDS was compared to that of NACT. We modeled cost and survival inputs using data from women in the SEER-Medicare database with ovarian cancer treated by either PDS or NACT between 1992 and 2009. Direct and indirect costs were discounted by an annual rate of 3%. Utility weights were obtained from published data. The incremental cost-effectiveness ratio (ICER) of PDS compared to NACT was calculated. Results In our model, women with stage IIIC EOC had a higher mean adjusted treatment cost for PDS when compared to NACT ($31,945 vs $30,016) but yielded greater quality-adjusted life-years (QALYs) (1.79 vs 1.69). The ICER was $19,359/QALY gained. Women with stage IV EOC had a higher mean adjusted treatment cost following PDS when compared to NACT ($31,869 vs $27,338) but yielded greater QALYs (1.69 vs 1.66). The ICER was $130,083/QALY gained. A sensitivity analysis showed that for both PDS and NACT the ICER was sensitive to incremental changes in the utility weight. Conclusion PDS is significantly more cost-effective for women with stage IIIC when compared to NACT. In women with stage IV EOC, PDS is also more cost-effective though the QALYs gained are much more costly and exceed a $50,000 willingness to pay. PMID:27536150

    Primary malignant melanoma of the oral cavity is a rare neoplasm, especially on the tongue. We report a case of mucosal melanoma at the base of the tongue, an extremely rare location (only about 30 cases have been reported in literature). The extension study doesn´t revealed distant metastatic lesions. The patient was treated by subtotal glossectomy and bilateral functional neck dissection. Tongue is one of the most difficult structures to reconstruct, because of their central role in phonation, swallowing and airway protection. The defect was reconstructed with anterolateral thigh free flap. Surgical treatment was supplemented with adjuvant immunotherapy. The post-operative period was uneventful. At present, 24 months after surgery, patient is asymptomatic, there isn´t evidence of recurrence of melanoma and he hasn´t any difficulty in swallowing or phonation. Key words:Malignant mucosal melanoma, anterolateral thigh free flap, phonation, swallowing. PMID:25593674

    Ovarian cancer is the leading cause of death among gynecological malignancies. It is detected at late stages when the disease is spread through the abdominal cavity in a condition known as peritoneal carcinomatosis. Thus, there is an urgent need to develop novel therapeutic interventions to target advanced stages of ovarian cancer. Mammary serine protease inhibitor (Maspin) represents an important metastasis suppressor initially identified in breast cancer. Herein we have generated a sequence-specific zinc finger artificial transcription factor (ATF) to up-regulate the Maspin promoter in aggressive ovarian cancer cell lines and to interrogate the therapeutic potential of Maspin in ovarian cancer. We found that although Maspin was expressed in some primary ovarian tumors, the promoter was epigenetically silenced in cell lines derived from ascites. Transduction of the ATF in MOVCAR 5009 cells derived from ascitic cultures of a TgMISIIR-TAg mouse model of ovarian cancer resulted in tumor cell growth inhibition, impaired cell invasion, and severe disruption of actin cytoskeleton. Systemic delivery of lipid-protamine-RNA nanoparticles encapsulating a chemically modified ATF mRNA resulted in inhibition of ovarian cancer cell growth in nude mice accompanied with Maspin re-expression in the treated tumors. Gene expression microarrays of ATF-transduced cells revealed an exceptional specificity for the Maspin promoter. These analyses identified novel targets co-regulated with Maspin in human short-term cultures derived from ascites, such as TSPAN12, that could mediate the anti-metastatic phenotype of the ATF. Our work outlined the first targeted, non-viral delivery of ATFs into tumors with potential clinical applications for metastatic ovarian cancers. PMID:22782891

    The association between neoplastic disease and thromboembolic disorders was first recognized by Trousseau in 1865. Blood coagulation abnormalities have been reported in the majority of patients with cancer, including those with ovarian carcinoma. However, Trousseau's syndrome (TS) has rarely been reported in women with ovarian carcinoma. We herein report a case series of TS, notably in the brain, in association with gynecological malignant disease, and emphasize the difficulties associated with the management of these thromboembolic effects. The aim of this study was to present our experience with 5 TS patients whose condition was effectively controlled through treatment of the primary malignant disease. Therefore, we suggest that patients with TS may be cured by tumor resection, even if they have severe thromboembolic disease, such as cerebral or pulmonary infarction. PMID:27330786

    AIM: To discriminate between adenocarcinomas that are primary to the ovary and metastatic to the ovary, especially of colonic and breast origin, by immunohistochemistry, using stepwise discriminant analysis or a decision tree. METHODS: 312 routinely processed, formalin fixed tissue specimens were used. The tumours were divided into a learning set (n = 159), composed of primary tumours of ovary, breast, and colon, and a test set, comprising 134 metastases from these sites and an additional 19 primary ovarian carcinomas. The immunohistochemical panel was composed of antibodies against cytokeratin 7 (CK7) and 20 (CK20), CA125, vimentin, carcinoembryonic antigen (CEA), gross cystic disease fluid protein-15 (GCDFP-15), and the oestrogen receptor (ER). The staining results of the tumours were expressed as the product of the staining intensity and the percentage of positive tumour cells. Analyses were first performed on the learning set and then evaluated on the test set. RESULTS: Although the immunostaining patterns showed a considerable overlap between the three types of adenocarcinoma, the breast carcinomas were typically positive for GCDFP-15 and often for ER, and negative for vimentin. Ovarian carcinomas were always positive for CK7 and to a lesser extent for CA125. Colonic carcinomas showed prominent positivity for CEA and CK20, while no staining was seen for ER and vimentin. In discriminant analysis, six antibodies (alpha CK7, alpha CK20, alpha CA125, alpha CEA, alpha ER, and alpha GCDFP-15) appeared to be necessary for optimal classification: 89% of the learning set and 82% of the test set were classified correctly. In the decision tree, only four antibodies (alpha CK7, alpha CEA, alpha ER, and alpha GCDFP-15) were used to obtain a correct classification score of 89% for the learning set and 84% for the test set. CONCLUSIONS: Using a semiquantitative assessment of the immunostaining results by a restricted panel of six antibodies with stepwise discriminant

    Introduction The issue of conserving the ovaries at hysterectomy in premenopausal women with benign gynecologic disease has been the subject of considerable controversy. Some clinicians prefer prophylactic oophorectomy in premenopausal women during hysterectomy to prevent future development of malignant changes in conserved ovaries. Other clinicians prefer to conserve apparently normal ovaries, because bilateral oophorectomy in premenopausal women results in an abrupt imbalance, sudden onset of menopausal symptoms, decreased libido, increased cardiovascular risk and osteoporosis. Material and methods Two hundred and twenty multipara women (who had completed their families), with benign uterine pathology were included in this prospective study for abdominal hysterectomy with bilateral ovarian preservation. Pre-operative vaginal ultrasound, Doppler studies, diagnostic hysteroscopy and endometrial biopsy were done followed by laboratory studies including Anti-mullerian hormone (AMH), follicle stimulating hormone (FSH) and estradiol for all studied women. Doppler studies, AMH, FSH and estradiol were repeated 6 and 12 months post-operative for assessment of the ovarian function and ovarian blood supply after hysterectomy. Results Pre-operative AMH, FSH and estradiol of the studied women were statistically insignificant compared to AMH, FSH and estradiol 6 and 12 months post-operative. Twelve months post-operative right and left ovarian volumes (6.92 ± 0.18 and 6.85 ± 0.19 cm3, respectively) were significantly larger than pre-operative right and left ovarian volumes (6.19 ± 0.22 and 5.86 ± 0.23 cm3, respectively), and, 12 months post-operative right and left ovarian pulsatility indices (2.92 ± 0.15 and 2.96 ± 0.16 cm/s, respectively) were significantly lower than pre-operative right and left ovarian pulsatility indices (3.45 ± 0.19 and 3.36 ± 0.2 cm/s, respectively). Eight (3.6%) cases of the studied women developed an ovarian cyst 6 months after hysterectomy, 3

    The tumour suppressor p53 is mutated in cancer, including over 96% of high-grade serous ovarian cancer (HGSOC). Mutations cause loss of wild-type p53 function due to either gain of abnormal function of mutant p53 (mutp53), or absent to low mutp53. Massively parallel sequencing (MPS) enables increased accuracy of detection of somatic variants in heterogeneous tumours. We used MPS and immunohistochemistry (IHC) to characterise HGSOCs for TP53 mutation and p53 expression. TP53 mutation was identified in 94% (68/72) of HGSOCs, 62% of which were missense. Missense mutations demonstrated high p53 by IHC, as did 35% (9/26) of non-missense mutations. Low p53 was seen by IHC in 62% of HGSOC associated with non-missense mutations. Most wild-type TP53 tumours (75%, 6/8) displayed intermediate p53 levels. The overall sensitivity of detecting a TP53 mutation based on classification as ‘Low’, ‘Intermediate’ or ‘High’ for p53 IHC was 99%, with a specificity of 75%. We suggest p53 IHC can be used as a surrogate marker of TP53 mutation in HGSOC; however, this will result in misclassification of a proportion of TP53 wild-type and mutant tumours. Therapeutic targeting of mutp53 will require knowledge of both TP53 mutations and mutp53 expression. PMID:27189670

    New therapeutic modalities are needed for ovarian cancer, the most lethal gynecologic malignancy. Recent clinical trials have demonstrated the impressive therapeutic potential of adoptive therapy using chimeric antigen receptor (CAR)-redirected T cells to target hematological cancers, and emerging studies suggest a similar impact may be achieved for solid cancers. We sought determine whether genetically-modified T cells targeting the CE7-epitope of L1-CAM, a cell adhesion molecule aberrantly expressed in several cancers, have promise as an immunotherapy for ovarian cancer, first demonstrating that L1-CAM was highly over-expressed on a panel of ovarian cancer cell lines, primary ovarian tumor tissue specimens, and ascites-derived primary cancer cells. Human central memory derived T cells (TCM) were then genetically modified to express an anti-L1-CAM CAR (CE7R), which directed effector function upon tumor antigen stimulation as assessed by in vitro cytokine secretion and cytotoxicity assays. We also found that CE7R+ T cells were able to target primary ovarian cancer cells. Intraperitoneal (i.p.) administration of CE7R+ TCM induced a significant regression of i.p. established SK-OV-3 xenograft tumors in mice, inhibited ascites formation, and conferred a significant survival advantage compared with control-treated animals. Taken together, these studies indicate that adoptive transfer of L1-CAM-specific CE7R+ T cells may offer a novel and effective immunotherapy strategy for advanced ovarian cancer. PMID:26761817

    The incidence of ovarian tumors diagnosed during pregnancy is between 0.3 and 5.4% (LE2). The most common ovarian tumors diagnosed during pregnancy are functional cysts diagnosed incidentally during the first trimester ultrasound (LE2) and spontaneous regression is often observed. Dermoid cysts and cystadenoma are the most frequent organic benign ovarian tumors diagnosed during pregnancy (LE2). The main complication of presumed benign ovarian tumor (PBOT) during pregnancy is adnexal torsion and is estimated at around 8% (LE2), especially at the end of the first trimester and during the second trimester (LE4). Tumor markers are not reliable during pregnancy to assess the risk of malignancy of ovarian tumor (LE2). Ultrasound remains the gold standard for characterizing an ovarian tumor during pregnancy (LE3), but with a lower specificity for the diagnosis of malignancy. Pelvic MRI is accurate in the diagnosis of ovarian tumors during pregnancy and brings additional information to ultrasound (LE4). Ultrasound-guided aspiration of ovarian tumors is not recommended during pregnancy (grade C). Expectation is recommended in cases of PBOT during pregnancy, which does not enlarge (grade C). Whatever the gestational age, surgery is recommended in patients with symptoms suggesting an adnexal torsion (grade C). Laparoscopy is possible during the first and second trimester of pregnancy for the management of symptomatic PBOT (LE3). The risk of miscarriage following surgery (laparoscopy and laparotomy) for ovarian tumor during pregnancy is estimated at 2.8% (LE3). The route of delivery should not be modified by the ovarian tumour, except in case of praevia cyst requiring a cesarean section, a complication or suspicion of malignancy (grade C). Surgical treatment of PBOT may be performed during a cesarean section indicated for another reason. The risk of torsion is increased during the postpartum period (LE4). PMID:24210242

    Ovarian carcinoma is the leading cause of death from gynecologic malignancy in the US. Factors such as the molecular heterogeneity of ovarian tumors and frequent diagnosis at advanced stages hamper effective disease treatment. There is growing emphasis on the identification and development of targeted therapies to disrupt molecular pathways in cancer. The epidermal growth factor (EGF) receptor is one such protein target with potential utility in the management of ovarian cancer. This paper will discuss contributions of EGF receptor activation to ovarian cancer pathogenesis and the status of EGF receptor inhibitors and EGF receptor targeted therapies in ovarian cancer treatment.

    Extra-ovarian yolk sac tumor arising in the omentum is extremely rare. As yolk sac tumor originated from the omentum has been rarely reported, its clinical information is very limited. The authors encountered a case of yolk sac tumor originated from the omentum, and reported the case herein. A 32-year-old woman was presented with developed low abdominal distension for a month. Magnetic resonance imaging findings were suggestive of ovarian malignancy with ascites and peritoneal seeding nodules. Explorative laparotomy was performed and then the findings from frozen biopsy of omentum were suggestive of poorly differentiated tumor though whether it was primary or metastatic was uncertain. Thus, staging laparotomy were performed. Histopathology confirmed that the tumor was a yolk sac tumor of omentum origin. Then, 6 cycles of postoperative adjuvant chemotherapy at intervals of 3 weeks were performed using bleomycin, etoposide, and cisplatin regimen. Four-year outpatient follow-up thereafter showed no relapse. PMID:24396822

    Splenic metastases are rare. Usually, they are part of a disseminated disease and located on the splenic capsule. Common sources are breast cancer, lung cancer and malignant melanoma. SoLitary splenic metastases are rare, usuaLLy located in the splenic parenchyma and metastasizing via the hematogenous route. Splenic metastases from ovarian carcinoma are usuaLly part of a disseminated disease, located on the splenic capsule and metastasize via the peritoneum. Splenic metastases from endometriaL carcinoma are usuaLLy solitary, Located in the splenic parenchyma and metastasize via the hematogenous route. Splenic metastases from cervical carcinoma are divided equally between metastases as part of a disseminated disease and soLitary metastases. Less than 100 cases of solitary splenic metastases have been reported with half of them being metastases from female genital tract malignancies: 30--ovarian carcinoma; 11--endometriaL carcinoma; 8--cervical carcinoma; and 1--tubal carcinoma. Few cases have been reported of splenic rupture because of metastases from choriocarcinoma. Splenic metastases as part of a disseminated disease are associated with poor prognosis, and splenectomy--apart from cases in which it might assist in achieving optimaL debulking--is not effective. Solitary splenic metastases represent a more moderate disease and the treatment of choice is splenectomy. SoLitary splenic metastases may be detected after an interval from the diagnosis of the primary disease. Hence, patients who had been treated for female genital tract malignancy, even if they are asymptomatic, need a long-term follow-up, including serial imaging studies of the spleen. PMID:20929072

    Purpose: Brachytherapy (BT) is an important treatment technique for uterine corpus malignancies. We modeled the optimal proportion of these cases that should be treated with BT-the optimal rate of brachytherapy utilization (BTU). We compared this optimal BTU rate with the actual BTU rate. Methods and Materials: Evidence-based guidelines and the primary evidence were used to construct a decision tree for BTU for malignancies of the uterine corpus. Searches of the literature to ascertain the proportion of patients who fulfilled the criteria for BT were conducted. The robustness of the model was tested by sensitivity analyses and peer review. A retrospective Patterns of Care Study of BT in New South Wales for 2003 was conducted, and the actual BTU for uterine corpus malignancies was determined. The actual BTU in other geographic areas was calculated from published reports. The differences between the optimal and actual rates of BTU were assessed. Results: The optimal uterine corpus BTU rate was estimated to be 40% (range, 36-49%). In New South Wales in 2003, the actual BTU rate was only 14% of the 545 patients with uterine corpus cancer. The actual BTU rate in 2001 was 11% in the Surveillance, Epidemiology, and End Results areas and 30% in Sweden. Conclusion: The results of this study have shown that BT for uterine corpus malignancies is underused in New South Wales and in the Surveillance, Epidemiology, and End Results areas. Our model of optimal BTU can be used as a quality assurance tool, providing an evidence-based benchmark against which can be measured actual patterns of practice. It can also be used to assist in determining the adequacy of BT resource allocation.

    We here analyzed the prevalence of extra-thyroidal malignancies (EM) in 6,386 female patients affected by different thyroid disease (TD). At first, an age-matched analysis of EM in all patients was performed. We then evaluated EM prevalence in four TD diagnostic categories: non-nodular TD (n = 2,159); solitary nodule (n = 905); multinodular TD (n = 2,871); differentiated thyroid cancers (n = 451). Finally, patients were grouped based on the absence (n = 3,820) or presence of anti-thyroglobulin (TgAb) and/or anti-thyroperoxidase (TPOAb) (n = 2,369), or anti-Thyroid Stmulating Hormone (TSH) receptor autoantibodies (n = 197). A total of 673 EM were recorded. EM prevalence in TD patients was higher compared to the general population (Odds Ratio, OR 3.21) and the most frequent EM was breast cancer (OR 3.94), followed by colorectal (OR 2.18), melanoma (OR 6.71), hematological (OR 8.57), uterus (OR 2.52), kidney (OR 3.40) and ovary (OR 2.62) neoplasms. Age-matched analysis demonstrated that the risk of EM was maximal at age 0-44 yr (OR 11.28), remaining lower, but significantly higher that in the general population, in the 45-59 and 60-74 year age range. Breast and hematological malignancies showed an increased OR in all TD, while other cancers associated with specific TD. An increased OR for melanoma, breast and hematological malignancies was observed in both TPOAb and/or TgAb autoantibody negative and positive patients, while colorectal, uterus, kidney and ovary cancers showed an increased OR only in thyroid autoantibody negative patients. In conclusions, women affected by both benign and malignant TD, especially at a younger age and in absence of thyroid autoimmunity, have an increased risk of developing primary EM, thus requiring a careful follow-up and surveillance.

    Both hereditary factors (e.g., BRCA1) and nicotinamide adenine dinucleotide (NAD)-dependent metabolic pathways are implicated in the initiation and progression of ovarian cancer. However, whether crosstalk exists between BRCA1 and NAD metabolism remains largely unknown. Here, we showed that: (i) BRCA1 inactivation events (mutation and promoter methylation) were accompanied by elevated levels of NAD; (ii) the knockdown or overexpression of BRCA1 was an effective way to induce an increase or decrease of nicotinamide phosphoribosyltransferase (Nampt)-related NAD synthesis, respectively; and (iii) BRCA1 expression patterns were inversely correlated with NAD levels in human ovarian cancer specimens. In addition, it is worth noting that: (i) NAD incubation induced increased levels of BRCA1 in a concentration-dependent manner; (ii) Nampt knockdown-mediated reduction in NAD levels was effective at inhibiting BRCA1 expression; and (iii) the overexpression of Nampt led to higher NAD levels and a subsequent increase in BRCA1 levels in primary ovarian cancer cells and A2780, HO-8910 and ES2 ovarian cancer cell lines. These results highlight a novel link between BRCA1 and NAD. Our findings imply that genetic (e.g., BRCA1 inactivation) and NAD-dependent metabolic pathways are jointly involved in the malignant progression of ovarian cancer. PMID:25486197

    Ovarian cancer is possibly the sixth most common malignancy worldwide, in Mexico representing the fourth leading cause of gynecological cancer death more than 70% being diagnosed at an advanced stage and the survival being very poor. Ovarian tumors are classified according to histological characteristics, epithelial ovarian cancer as the most common (~80%). We here used high-density microarrays and a systems biology approach to identify tissue-associated deregulated genes. Non-malignant ovarian tumors showed a gene expression profile associated with immune mediated inflammatory responses (28 genes), whereas malignant tumors had a gene expression profile related to cell cycle regulation (1,329 genes) and ovarian cell lines to cell cycling and metabolism (1,664 genes).

There were no statistically significant differences between the PPSC and PSOC patients with regard to the mean age, menopausal status, parity, ascites fluid volume, proportion of stage IV disease, and the rate of optimal debulking achieved. The median disease-free interval was 15 and 18 months; the median survival was 21 and 26 months; and the 5-year survival was 18 and 24% for the PPSC and PSOC groups, respectively. The median survival time for patients with a residual tumor > or = 2 cm was 20.5 and 24 months, and for residual tumor > or = 2 cm was 46 and 41 months, in PPSC and PSOC patients, respectively. Survival was thus better, in both groups, when residual disease at the end of the operation was < 2 cm, though this was statistically significant only for PSOC (P < 0.02). We conclude that patients with PPSC should be treated as other stage II-IV PSOC patients. Combining optimal debulking with a platinum-based chemotherapy may offer the patient the most effective treatment. PMID:8774644

    Objective To estimate electroporation (EP) influence on malignant and normal cells. Methods Two cell lines including human malignant melanoma (Me-45) and normal human gingival fibroblast (HGFs) were used. EP parameters were the following: 250, 1 000, 1 750, 2 500 V/cm; 50 µs by 5 impulses for every case. The viability of cells after EP was estimated by MTT assay. The ultrastructural analysis was observed by transmission electron microscope (Zeiss EM 900). Results In the current study we observed the intracellular effect following EP on Me-45 and HGF cells. At the conditions applied, we did not observe any significant damage of mitochondrial activity in both cell lines treated by EP. Conversely, we showed that EP in some conditions can stimulate cells to proliferation. Some changes induced by EP were only visible in electron microscopy. In fibroblast cells we observed significant changes in lower parameters of EP (250 and 1 000 V/cm). After applying higher electric field intensities (2 500 V/cm) we detected many vacuoles, myelin-like bodies and swallowed endoplasmic reticulum. In melanoma cells such strong pathological modifications after EP were not observed, in comparison with control cells. The ultrastructure of both treated cell lines was changed according to the applied parameters of EP. Conclusions We can claim that EP conditions are cell line dependent. In terms of the intracellular morphology, human fibroblasts are more sensitive to electric field as compared with melanoma cells. Optimal conditions should be determined for each cell line. Summarizing our study, we can conclude that EP is not an invasive method for human normal and malignant cells. This technique can be safely applied in chemotherapy for delivering drugs into tumor cells. PMID:23569735

    Women with a diagnosis of breast cancer are at increased risk of second primary cancers, and the identification of risk factors for the latter may have clinical implications. We have followed-up for 11 years 10,045 women with invasive breast cancer from a European cohort, and identified 492 second primary cancers, including 140 contralateral breast cancers. Expected and observed cases and Standardized Incidence Ratios (SIR) were estimated using Aalen-Johansen Markovian methods. Information on various risk factors was obtained from detailed questionnaires and anthropometric measurements. Cox proportional hazards regression models were used to estimate the role of risk factors. Women with breast cancer had a 30% excess risk for second malignancies (95% confidence interval-CI 18-42) after excluding contralateral breast cancers. Risk was particularly elevated for colorectal cancer (SIR, 1.71, 95% CI 1.43-2.00), lymphoma (SIR 1.80, 95% CI 1.31-2.40), melanoma (2.12; 1.63-2.70), endometrium (2.18; 1.75-2.70) and kidney cancers (2.40; 1.57-3.52). Risk of second malignancies was positively associated with age at first cancer, body mass index and smoking status, while it was inversely associated with education, post-menopausal status and a history of full-term pregnancy. We describe in a large cohort of women with breast cancer a 30% excess of second primaries. Among risk factors for breast cancer, a history of full-term pregnancy was inversely associated with the risk of second primary cancer. PMID:25650288

  2. Mucin-1 and its relation to grade, stage and survival in ovarian carcinoma patients

    PubMed Central

    2012-01-01

    Background Mucin-1 is known to be over-expressed by various human carcinomas and is shed into the circulation where it can be detected in patient’s serum by specific anti-Mucin-1 antibodies, such as the tumour marker assays CA 15–3 and CA 27.29. The prognostic value of Mucin-1 expression in ovarian carcinoma remains uncertain. One aim of this study was to compare the concentrations of Mucin-1 in a cohort of patients with either benign or malignant ovarian tumours detected by CA 15–3 and CA 27.29. Another aim of this study was to evaluate Mucin-1 expression by immunohistochemistry in a different cohort of ovarian carcinoma patients with respect to grade, stage and survival. Methods Patients diagnosed with and treated for ovarian tumours were included in the study. Patient characteristics, histology including histological subtype, tumour stage, grading and follow-up data were available from patient records. Serum Mucin-1 concentrations were measured with ELISA technology detecting CA 15–3 and CA 27.29, Mucin-1 tissue expression was determined by immunohistochemistry using the VU4H5 and VU3C6 anti-Mucin-1 antibodies. Statistical analysis was performed by using SPSS 18.0. Results Serum samples of 118 patients with ovarian tumours were obtained to determine levels of Mucin-1. Median CA 15–3 and CA 27.29 concentrations were significantly higher in patients with malignant disease (p< 0.001) than in patients with benign disease. Paraffin-embedded tissue of 154 patients with ovarian carcinoma was available to determine Mucin-1 expression. The majority of patients presented with advanced stage disease at primary diagnosis. Median follow-up time was 11.39 years. Immunohistochemistry results for VU4H5 showed significant differences with respect to tumour grade, FIGO stage and overall survival. Patients with negative expression had a mean overall survival of 9.33 years compared to 6.27 years for patients with positive Mucin-1 expression. Conclusions This study found

    In this paper, we present the construction of an optical-resolution photoacoustic microscopy (OR-PAM) system and studies done on the characterization of human ovarian tissue with malignant and benign features ex vivo. PAM images of the ovaries showed more detailed blood vessel distributions with much higher resolution compared with conventional photoacoustic images obtained with array transducers. In all, 29 PAM images (20 from normal ovaries and 9 from malignant ovaries) were studied. Eight different features were extracted quantitatively from the PAM images, and a generalized linear model (GLM) was used to classify the ovaries as normal or malignant. By using the GLM, a specificity of 100% and a sensitivity of 100% were obtained for the training set. These preliminary results demonstrate the feasibility of our PAM system in mapping microvasculature networks, as well as characterizing the ovarian tissue, and could be extremely valuable in assisting surgeons for in vivo evaluation of ovarian tissue.

    Cancer/testis (CT) antigens are potential targets for cancer immunotherapy, with NY-ESO-1 being among the most immunogenic. In several clinical trials in malignant melanoma (MM) patients, NY-ESO-1 protein/peptides showed clear evidence of inducing specific immunity. However, little is known about NY-ESO-1 expression in primary and metastatic MM and its relationship to disease progression. We analyzed NY-ESO-1 expression immunohistochemically in a series of primary and metastatic MMs and its relation to prognostic parameters and survival. We studied 61 primary and 63 metastatic MM specimens (from 61 and 56 patients, respectively). The prevalence of NY-ESO-1 expression was significantly higher in metastatic versus primary tumors [18/56 (32%) versus 8/61 (13%), P = 0.015]. There was a significant association between initial stage at presentation and NY-ESO-1 expression [stage I (3.45%), stage II (9.52%) and stage III (45.45%), P = 0.0014]. Primary MMs expressing NY-ESO-1 were significantly thicker than NY-ESO-1 negative cases (median thickness 4.7 mm versus 1.53 mm respectively, P = 0.03). No significant difference was seen in overall survival. In conclusion, NY-ESO-1 is more frequently expressed in metastatic than in primary MM and its expression is associated with thicker primary lesions and a higher frequency of metastatic disease, indicative of a worse prognosis. Our study suggests that patients with metastatic MM who express NY-ESO-1 may benefit from NY-ESO-1-based immunotherapy. PMID:17625806

    With about 22,000 new cases estimated in 2012 in the US and 15,500 related deaths, ovarian cancer is a heterogeneous and aggressive disease. Even though most of patients are sensitive to chemotherapy treatment following surgery, recurring disease is almost always lethal, and only about 30% of the women affected will be cured. Thanks to a better understanding of the molecular mechanisms underlying ovarian cancer malignancy, new therapeutic options with molecular-targeted agents have become available. This review discusses the rationale behind molecular-targeted therapies and examines how newly identified molecular targets may enhance personalized therapies for ovarian cancer patients.

    Olaparib, an oral poly(ADP-ribose) polymerase (PARP) inhibitor, is the first FDA-approved drug in its class for patients with ovarian cancer, specifically in a subset of patients with BRCA mutations and prior chemotherapy treatments. PARP inhibitors have had other implications in different solid tumor types including breast, gastric and pancreatic malignancies. In light of the recent FDA approval of olaparib for the treatment of ovarian cancer, this article aims to outline the mechanisms and implications of the drug. With a favorable adverse event profile and improved outcomes, including progression-free survival, olaparib has demonstrated augmentation to therapeutic options in the treatment of ovarian cancer.

    Endometriosis is a common condition in women of reproductive age. According to several epidemiological studies endometriosis may be associated with increased risk of various malignancies. However, endometriosis-associated malignancy (EAM) is defined by certain histological criteria. About 80 % of EAM have been found in the ovary, whereas 20 % are localized in extragonadal sites like intestine, rectovaginal septum, abdominal wall, pleura and others. Some authors suggest that EAM arise from atypical endometriosis as an intermediate lesion between endometriosis and cancer. Moreover, a number of genetic alterations, like loss of heterozygosity (LOH), PTEN, ARID1 A and p53 mutations have been found in both endometriosis and EAM. Endometriosis-associated ovarian cancer (EAOC) is mostly a well or intermediately differentiated tumor of endometrioid or clear cell histological sub-type. Women affected by EAOC are on average five to ten years younger than non-EAOC patients; in most of the cases EAOC is a low stage disease with favorable clinical outcome. Since EAM is a rare condition systematic data on EAM are still missing. A systematic retrospective study on endometriosis-associated malignancies (EAM study) is currently being conducted by the Endometriosis Research Foundation together with the study groups on ovarian and uterine tumors of the working group for gynecological oncology (AGO) (gyn@mlk-berlin.de).

    The primary objectives of the present study are to determine the period of onset of ovarian insufficiency after surgery and to confirm potential risk factors for ovarian insufficiency after surgery for the removal of benign ovarian cysts. Data were obtained from 75 patients who underwent surgery for benign ovarian cysts prior to the onset of ovarian insufficiency. Our analysis included 835 ovarian insufficiency patients who were referred to our institution from July 2003 to July 2013. Several epidemiological parameters of ovarian insufficiency after surgery (age at operation, period of onset of ovarian insufficiency, operation procedure, and pathological diagnosis) were investigated. Of the 835 patients who had ovarian insufficiency, 75 patients (9.0%) underwent ovarian surgery before the onset of ovarian insufficiency. Of those 75 patients, 66 patients (88.0%) underwent cystectomy. For the majority of the 75 patients the surgical indication was the presence of endometriotic cysts (57 patients; 76.0%). Twelve patients (16.0%) underwent multiple surgeries (all bilateral cystectomies). The mean age of the patients at the time of surgery was 27.8±5.5 years-old, and the mean period of onset of ovarian insufficiency was 5.8±3.8 years. In patients with cystectomy, the patient's age at the time of surgery and period of onset of ovarian insufficiency was well-correlated (coefficient of correlation; hemilateral endometriotic cystectomy: -0.64, bilateral endometriotic cystectomy: -0.61, and multiple endimetriotic cystectomy: -0.40). We found that cystectomy of endometriotic cysts is the potential risk factor for ovarian insufficiency after surgery, at times, the onset of ovarian insufficiency long after cystectomy. Therefore, it is important to monitor ovarian reserve for an extended period of time after ovarian surgery. It is particularly important to monitor ovarian reserve long-term for patients who wish to conceive in the future and to suggest a variety of infertility

    Breast cancer is the most common malignant neoplastic process and the second cause of death for women. Ovarian cancer, despite having a lower incidence, represents an important cause of morbidity and mortality because it is usually discovered in advanced stages. The presence of both forms of cancer in a patient is associated with a high risk of BRCA1 gene mutations, which are responsible, together with BRCA2 gene mutations, for most of the breast and ovarian cancer family. Our case is special because it presents a synchronous and a rare association of a primary ovarian dysgerminoma (with an incidence of less than 1% of ovarian cancers) and a primary breast carcinoma in a patient of 46 years old. Immunohistochemical examination was performed using a panel of five biomarkers: oestrogen receptor, progesterone receptor, Herceptest, p53 and BRCA1. In our case, we identified a negative hormonal status and the absence of HER2/neu expression but a positive immuno-expression for p53 protein and BRCA1 protein. Postoperative course was favourable for the patient after each surgery, and she was discharged with the recommendation to perform a genetic counselling. PMID:23618579

    2012-06-01

    Borderline ovarian tumours account for 10-20% of all epithelial ovarian cancer. Historically, standard primary surgery has included borderline ovarian tumours, omentectomy, peritoneal washing and multiple biopsies. As one-third of borderline ovarian tumours are diagnosed in women under the age of 40 years, fertility-sparing treatment has been more frequently used in the past 10 years. Fertility drugs are well tolerated in women with infertility after fertility-sparing surgery. Careful selection of candidates is necessary. Laparoscopic techniques can be used, but should be reserved for oncologic surgeons. This conservative treatment increases the rate of recurrence, albeit with no effect on survival. The pregnancy rate is nearly 50%, and most are achieved spontaneously. These women should be closely followed up. The question is whether this is acceptable from a gynaecologic oncologic point of view. For this reason, we will discuss recently published studies and gynaecologic oncologic concerns about the mode of fertility-sparing surgery and its consequences. PMID:22321906

    HEALTH ISSUE: In Canada, cancers of the endometrium, ovaries, vulva, vagina, placenta and adnexa account for 11% of all malignant neoplasms in women and 81% of all genital cancers. Although the incidence and mortality from vulvar and vaginal cancers are very low, endometrium and ovarian cancer are important public health problems. KEY FINDINGS: In Canada, there has been no appreciable improvement in survival for women with advanced endometrial (EC) or ovarian cancer (OC) over the past 30 years. The prognosis of EC is good for most patients because diagnosis is made at early stages. However, survival of OC is poor; more than 70% of cases are diagnosed at late stages. Up to 10% of OCs is linked to familial aggregation. Cancers of the vulva and of the vagina are very rare. The survival experience for women with the latter is worse than for those with the former. Both share many risk factors with cervical cancer and the recent developments in the study of HPV infection should be applicable to these diseases as well. Of particular interest will be the advent of vaccines for the primary prevention of HPV infection. DATA GAPS AND RECOMMENDATIONS: At present, the best available means to diagnose gynecologic malignancies is a detailed clinical examination, considering the totality of information on potential and proven risk factors, such as age, reproductive health, sexual practices, use unopposed estrogens or of oral contraceptives or tubal ligation, obesity, diet, smoking, and the familial clustering of some of these cancers.

    Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy in developed countries. Several promising steps toward individualized therapy have been taken recently due to increased knowledge of molecular biology. Multidisciplinary conferences for treatment planning and the centralization to tertiary surgical centers improve quality of surgery and survival. The primary treatment of EOC is radical surgery followed by adjuvant chemotherapy with carboplatin and paclitaxel. Bevacizumab added to the chemotherapy and used as maintenance treatment is standard in the primary treatment of patients with residual tumor or inoperable patients. The PARP inhibitor olaparib is recommended as maintenance treatment of women with platinum sensitive relapsed BRCA mutated high-grade serous EOC who have responded to platinum-based chemotherapy. BRCA testing should be offered to women with EOC. In platinum-resistant recurrence addition of bevacizumab to chemotherapy should be considered. PMID:26646960

    FMR1 premutation female carriers are at risk for Fragile X-associated primary ovarian insufficiency (FXPOI). Insights from knock-in mouse model have recently demonstrated that FXPOI is due to an increased rate of follicle depletion or an impaired development of the growing follicles. Molecular mechanisms responsible for this reduced viability are still unknown. In an attempt to provide new data on the mechanisms that lead to FXPOI, we report the first investigation involving transcription profiling of total blood from FMR1 premutation female carriers with and without FXPOI. A total of 16 unrelated female individuals (6 FMR1 premutated females with FXPOI; 6 FMR1 premutated females without FXPOI; and 4 no-FXPOI females) were studied by whole human genome oligonucleotide microarray (Agilent Technologies). Fold change analysis did not show any genes with significant differential gene expression. However, functional profiling by gene set analysis showed large number of statistically significant deregulated GO annotations as well as numerous KEGG pathways in FXPOI females. These results suggest that the impairment of fertility in these females might be due to a generalized deregulation of key signaling pathways involved in oocyte maturation. In particular, the vasoendotelial growth factor signaling, the inositol phosphate metabolism, the cell cycle, and the MAPK signaling pathways were found to be down-regulated in FXPOI females. Furthermore, a high statistical enrichment of biological processes involved in cell death and survival were found deregulated among FXPOI females. Our results provide new strategic approaches to further investigate the molecular mechanisms and potential therapeutic targets for FXPOI not focused in a single gene but rather in the set of genes involved in these pathways.

    Purpose/Objectives To identify changes in positive aspects of care (PAC) from the time of diagnosis to four months following the diagnosis in family caregivers of care recipients with primary malignant brain tumors. Design Longitudinal. Setting Dyads were recruited from neurosurgery clinics in Pittsburgh, PA, at the time of care recipients’ diagnosis with a primary malignant brain tumor. A second data collection took place four months following the diagnosis. Sample 89 caregiver and care recipient dyads. Methods Paired t tests were used to examine change in PAC, univariate analyses were used to determine predictors of PAC at four months, Mann-Whitney U tests and t tests were used to examine associations between categorical predictor variables and PAC at four months, and univariate linear regressions were used to examine associations between continuous predictors and PAC at four months. Main Research Variables The impact of sociodemographic factors, caregiver-perceived social support, mastery, neuroticism, and marital satisfaction on PAC. Findings Caregivers’ PAC scores during the first four months following diagnosis appeared to remain stable over time. Significant differences were found between the care recipient reasoning domain group at diagnosis and PAC score. Care recipients who scored below average were associated with caregivers with higher PAC scores. Caregiver PAC at four months following diagnosis was significantly predicted by care recipient reasoning and caregiver social support. Conclusions PAC scores appear to remain stable over time, although levels of PAC may be related to care recipients’ level of functioning. Future research should focus on the development of interventions for caregivers who report low levels of PAC at the time of diagnosis in an attempt to help these individuals identify PAC in their caregiving situation. Implications for Nursing Findings have clinical and research implications. Clinicians may be able to better identify
