    Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal neoplasm characterized by expression of both melanocytic and smooth muscle markers. PEComas are rarely encountered in the female genital tract. We here report a case of malignant primary PEComa of the ovary, and discuss the differential diagnosis. This represents the first case of primary typical malignant PEComa of the ovary.

    We investigated the pattern and frequency of ovarian metastases in patients with primary gastrointestinal malignancies and evaluated the response to surgery, chemotherapy and in three cases radiotherapy. The literature reports that this group of patients have a poor prognosis, but no report has specifically addressed the response to chemotherapy. Using a database which is generated prospectively, we analysed 51 patients with primary gastrointestinal malignancies and ovarian metastases. All patients received chemotherapy but only 36 were evaluable for response; five had adjuvant treatment and ten had non-measurable disease. Seventeen patients had surgical oophorectomy and three patients received radiotherapy. The overall response rate to chemotherapy was 22%; eight partial responses and no complete responses. When stratified according to site of response, 11 (31%) patients had a partial response at sites of extraovarian metastases and only five (14%) had a partial response in the ovaries. Seven patients with primary colorectal cancer had a differential response in favour of extraovarian sites. The median survival was 9 months for the 51 patients. Three premenopausal women with resected gastric carcinoma received adjuvant chemotherapy and relapsed only in the ovaries. In primary colorectal tumours the response of ovarian metastases to chemotherapy is less than that for other sites. Therefore, the ovary may be a sanctuary site for metastases which has important implications for adjuvant chemotherapy in women. These women could be followed up regularly by transvaginal ultrasonography to detect such metastases at an early stage when they would be amenable to surgical resection. Surgery should be considered for selected patients who develop metachronous metastases, as patients may be rendered disease free for several months. PMID:7819057

    The risk of second primary malignancy was assessed in a population-based cohort study of all persons registered with Hodgkin's disease (n = 2,970), ovarian cancer (n = 11,802) and testicular cancer (n = 2,013) in the South Thames Cancer Registry during the period 1961-80, to identify for further study those second malignancies which might be treatment-related. A total of 244 second malignancies was observed. After adjustment for age, sex and calendar period, the relative risk of any second malignancy was 1.4 (90% confidence interval (CI) 1.1-1.7) after Hodgkin's disease, 1.1 (90% CI 1.0-1.2) after ovarian cancer and 0.7 (90% CI 0.5-1.0) after testicular cancer. In particular, the relative risk for leukaemia was 11.9 after Hodgkin's disease, 3.7 after ovarian cancer and 2.5 after testicular cancer. Excess risks were also observed for cancers of the cervix and lung after Hodgkin's disease, for cancers of the breast, lung and rectum after ovarian cancer, and for contralateral testicular cancer. Confounding by social class or smoking does not explain these observations. The excess risks of leukaemia and of second cancer were higher in patients first diagnosed with Hodgkin's disease and ovarian cancer in the 1970s than for those first diagnosed in the 1960s. Increased use of multiple-agent chemotherapy regimes for these tumours in the 1970s may have contributed to these increases in excess risk. PMID:3663481

    Synchronous malignancies, including three or more tumours, are extremely rare. Herein, we present a case of a woman with a concurrent simultaneous endometrial, ovarian and fallopian tubal carcinoma with different histopathological characteristics. A 55-year-old postmenopausal woman with a diagnosis of endometrial adenocarcinoma by pipelle biopsy, underwent surgical staging. Final pathology result was reported as synchronous stage IA grade 2 endometrioid adenocarcinoma of the uterus, stage IA grade 2 mucinous adenocarcinoma of the right ovary and in situ serous cystadenocarcinoma of the right fallopian tube. In the postoperative period, patient followed without adjuvant therapy. To our knowledge, this a very rare case report in the literature of sychronous triple gynaecologic cancers including fallopian tube cancer and with the longest disease free survival time with over 39 months due to better prognosis than metastatic or advanced primitive diseases.

    The histogenesis of ovarian malignant mixed mesodermal tumours, which includes the concept of metaplastic carcinoma, is controversial. Four such tumours were examined for evidence of metaplastic transition from carcinoma to sarcoma using morphology and reticulin stains. Consecutive sections were stained immunohistochemically using cytokeratin and vimentin to determine whether cells at the interface between carcinoma and sarcoma expressed both cytokeratin and vimentin. There was no evidence of morphological, architectural, or immunohistochemical transitions from carcinoma to sarcoma in the four tumours studied. This suggests that ovarian malignant mixed mesodermal tumours are not metaplastic carcinomas but are composed of histogenetically different elements. Images PMID:2160478

    Ovarian borderline tumors are rare, their good prognosis depending on their stage at the time of diagnosis, and the presence of invasive implants. There is little information on tumor type identified intra-surgically, as well as on the most favorable treatment in borderline ovarian tumors. To determine the criteria of identification and presurgery and intra-surgery differentiation of the ovarian borderline tumors from the invasive carcinoma and benign ovarian tumors. This study included 54 patients with TPMS (ovarian borderline tumors) surgically treated in the past 22 years (January 1988-December 2009) at the 4th Gynecological Clinic of the lasi "Gr. T. Popa" University of Medicine and Pharmacy. In this interval 1,107 ovarian tumors: 575 benign, 478 malignant, and 54 TPMS (4.87%) were recorded. The age of the patients with borderline tumors ranged between 20 and 78 years, mean age 46 years, and the histological types were: mucinous (27 cases), serous (18 cases), mixed (8 cases), and Brenner tumor (1 case). We have analyzed the distribution of these cases according to the time when surgical treatment was performed. The frequency of borderline ovarian tumors in our study is 4.87%, lower than in the literature. We believe that this low percentage in our study is due to missing the microscopic data in some macroscopic benign tumors. By this research we aimed at elaborating a therapeutic strategy for each case using with discernment the modern treatment (surgery, chemotherapy, radiotherapy), as well as new chemical drugs with the goal of obtaining better results and longer survival. There are no tumor markers which could predict the progression of a borderline ovarian tumor to invasive tumors, but the invasive course is only 0.7%.

    Extremely rare ovarian primary tumors formed in a mature cystic teratomaare described in the literature. This research work studies the frequency of malignant mature cystic teratoma, as well as their clinical and morphological features and necessity of intraoperative histological examination of all teratomas. Cases histories of 56 patients, suffering from ovarian mature cystic teratomahave been studied in MC Shengavit in the period of 2003 - 2015. Among them 4 patients with the somatic malignancies were identified. Morphological methods, which are considered to be "gold standard" of tumor investigation, were used in staining the slides with hematoxylin - eosin. According to the literature the secondary malignant transformation rarely occurs and is typical in postmenopausal women, with a frequency of 0.17-3%. According to the results of our study, malignant tumors in mature cystic teratomas were observed in 4 (7,14%) from the total number of mature cystic teratomas (n=56). There was not revealed a correlation between the duration of the complaints, age of the patients, sizes of ovarian mature teratoma and malignization degree. Thus, the greatest difficulties of clinical diagnosis of malignant tumors in the ovarian mature cystic teratomas were in the early stage of the disease, because of a variety of clinical manifestations, not pathognomonic for malignization. All mentioned symptoms may be observed in the patients with usual mature cystic teratomas. Тhis cases confirm the necessity to take tissue samples from the other ovary for intraoperative histopathological evaluation in each case of mature cystic teratomas. It is necessary to examine a large number of tumor sites, to prevent errors in the assessment of the maturity degree of teratoma.

    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.

    Abstract Primary intracranial melanomas are uncommon and constitute approximately 1% of all melanoma cases and 0.07% of all brain tumors. In nature, these primary melanomas are very aggressive and can spread to other organs. We report an uncommon case of primary cerebral malignant melanoma—a challenging diagnosis guided by clinical presentations, radiological features, and surgical biopsy results, aiming to emphasize the importance of considering primary melanoma when making differential diagnoses of intracranial lesions. We present a rare case of a primary cerebral melanoma in the left temporal lobe. The mass appeared iso-hypodense on brain computed tomography (CT), short signal on T1-weighted magnetic resonance images (T1WI) and long signal on T2WI. It was not easy to make an accurate diagnosis before surgery. We showed the patient's disease course and reviewed related literatures, for readers’ reference. Written informed consent was obtained from the patient for publication of this case report and any accompanying images. Because of this, there is no need to conduct special ethic review and the ethical approval is not necessary. After surgery, the pathological examination confirmed the diagnosis of melanoma. The patient was discharged without any complications and went on to receive adjuvant radiochemotherapy. It is difficult to diagnose primary cerebral melanoma in the absence of any cutaneous melanosis. A high index of clinical suspicion along with good pathology reporting is the key in diagnosing these extremely rare tumors. PMID:28121927

    Ovarian tumors of low malignant potential (LMP) represent a pathologic subtype of ovarian tumor that possess many features common to malignant tumors including epithelial stratification, increased mitotic activity and atypical cellularity. These tumors, however, do not invade the ovarian stroma and have a much improved patient prognosis. Utilizing dinucleotide repeats, loss of heterozygosity (LOH) studies were performed on a total of 12 ovarian tumors of LMP in 5 regions found to have significant levels of LOH in malignant ovarian tumors. The regions chosen for study were 3p, 6q, 11p, 17p and 17q. LOH could be demonstrated in malignant ovarian tumors in loci from 3p, 11p and both chromosomal arms of 17 when compared to normal tissue from the same patient. Loss in malignant tumors was more common in loci mapped to 3p21 and to 11p15. OH was not noted in any samples for a repeat in the TP53 gene even though flanking markers on 17p were lost in 1 patient with a malignant tumor. Loss was not demonstrated in any of the loci examined from 6q in malignant ovarian tumors. LOH was not demonstrated in any of the 39 loci examined from any of the five chromosomal regions in the ovarian tumors of LMP. Cytogenetic analyses of these LMP tumors were consistent with lack of involvement in these chromosomal regions. These data suggest the mechanism of tumorigenesis is different in tumors of LMP from that in malignant ovarian tumors.

    Primary pineal malignant melanoma is a rare entity, with only thirteen cases reported in the world literature to date. We report a case of a 70-year-old man, who consulted with gait disturbance of six months duration, associated in the last month with dizziness, visual abnormalities and diplopia. No other additional melanocytic lesions were found elsewhere. The magnetic resonance showed a 25 mm expansive mass in the pineal gland that was associated with hydrocephaly, ventricular and transependimary oedema. The lesion was partially excised by a supracerebellar infratentorial approach. The histological examination revealed a melanoma. The patient received radiation therapy, but died of disease 16 weeks later. We herein review the literature on this rare tumour and comment on its clinical, radiological and histopathological features and differential diagnosis. PMID:24765293

    1994-09-01

    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.

    A 26 year old Nigerian nulliparous woman who presented in the medical emergency unit of a teaching hospital was referred after two weeks of management to the gynecology casualty with a diagnosis of malignant left ovarian cyst, because of the ascites, massive haemorrhagic pleural effusion, a left ovarian mass and an elevated C-125 marker. However, exploratory laparotomy, cytologic and histological examination of the pleural fluid and biopsied specimens revealed endometriosis. We present a case of intra and extra-pelvic endometriosis which simulated a malignant ovarian lesion and was histologically confirmed by cytology of the haemorrhagic pleural effusion and biopsy of the ovarian mass and peritoneal deposits obtained at laparotomy. This is to draw the attention of clinicians to endometriosis as a cause of pleural effusion, ascites and groin swelling which can simulate ovarian cancer.

    Mural nodules, which may be benign or malignant, are well recognized in ovarian mucinous neoplasms, especially of borderline type. Malignant mural nodules most commonly comprise anaplastic carcinoma but sarcomas of various types have been reported. We report 2 cases of osteosarcoma occurring in young women (aged 18 and 34) as malignant mural nodules in a Grade 1 ovarian mucinous carcinoma of intestinal type and a borderline mucinous tumor of intestinal type. Primary osteosarcomas of the ovary have been described either arising within a teratoma or as a pure neoplasm but, to the best of our knowledge, osteosarcoma occurring as a mural nodule in an ovarian mucinous neoplasm has not been reported. In both our cases, the tumor was Stage 1 at presentation and the patients were treated with surgery without adjuvant chemotherapy. Both patients are free of disease with follow-up of 12 and 18 mo.

    Ovarian serous neoplasms can have morphologic overlap with malignant mesothelioma. The distinction is clinically important, yet most studies have failed to identify immunostains that reliably distinguish these 2 tumor types. Recently, transcription factor PAX8 was shown to be a sensitive and relatively specific marker for Müllerian tumors. In addition, some studies suggest that h-caldesmon is sensitive and specific for mesothelioma when compared with serous ovarian tumors. The goal of this study was to evaluate whether PAX8 and h-caldesmon expression can successfully distinguish mesothelioma from serous ovarian tumors. Immunohistochemistry was carried out using PAX8 and h-caldesmon antibodies on archival tissue from 254 ovarian serous tumors and 50 mesothelial tumors. Nuclear and cytoplasmic immunoreactivity were considered positive for PAX8 and h-caldesmon, respectively. PAX8 staining was present in 99% of high-grade serous ovarian carcinomas and all (100%) low-grade ovarian carcinomas and serous borderline tumors; however, only 74% of these cases (188/254) were diffusely positive in more than 50% of tumors cells, and intensity ranged from strong to weak. None of the pleural malignant mesotheliomas were reactive with PAX8. However, 2/23 (9%) peritoneal malignant mesotheliomas showed focal and/or weak staining for PAX8; the remaining cases were negative. Two well-differentiated papillary mesotheliomas and 1 multicystic mesothelioma each showed some staining for PAX8. h-caldesmon was negative in all serous neoplasms and all mesothelial neoplasms, except 1 pleural malignant mesothelioma which showed patchy immunoreactivity. Strong PAX8 staining is highly specific (P<0.00001) for ovarian serous tumors when compared with malignant mesotheliomas of the peritoneum and pleura. The presence of weak staining for PAX8 in the 3 "noninvasive" mesotheliomas questions the use for PAX8 in this differential diagnosis. On the basis of this study, h-caldesmon is not a useful marker

    Given a 10% malignancy rate in pediatric ovarian masses, what preoperative factors are helpful in distinguishing those at higher risk to risk stratify accordingly? After institutional review board approval (IRB#022008-095), a 15(1/2)-year retrospective review of operative ovarian cases was performed. A total of 424 patients were identified, with a mean age 12.5 years (range, 1 day to 19 years), without an age disparity between benign (12.54 years, 89%) and malignant (11.8 years, 11%) cases. The 1- to 8-year age group had the highest percentage of malignancies (22%; odds ratio [OR], 3.02; 95% confidence interval [CI], 1.33-6.86). A chief complaint of mass or precocious puberty versus one of pain had an OR for malignancy of 4.84 and 5.67, respectively (95% CI, 2.48-9.45 and 1.60-20.30). Imaging of benign neoplasms had a mean size of 8 cm (range, 0.9-36 cm) compared with malignancies at 17.3 cm (6.2-50 cm, P < .001). An ovarian mass size of 8 cm or longer on preoperative imaging had an OR of 19.0 for malignancy (95% CI, 4.42-81.69). Ultrasound or computed tomographic findings of a solid mass, although infrequent, were most commonly associated with malignancy (33%-60%), compared with reads of heterogeneous (15%-21%) or cystic (4%-5%) lesions. The malignancies (n = 46) included germ cell (50%, n = 23), stromal (28%, n = 13), epithelial (17%, n = 8), and other (4%, n = 2). Tumor markers obtained in 71% of malignancies were elevated in only 54%, whereas 6.5% of those sent in benign cases were similarly elevated. Elevated beta-human chorionic gonadotropin (beta-HCG), alpha fetoprotein (alphaFP), and cancer antigen 125 (CA-125) were significantly associated with malignancy (P < .02) and an elevated carcinoembryonic antigen (CEA) was not (P = .1880). This reported series of pediatric ovarian masses demonstrates that preoperative indicators that best predict an ovarian malignancy are a complaint of a mass or precocious puberty, a mass exceeding 8 cm or a mass with solid

    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

    Ovarian cancer is the ninth most common malignancy and the fifth leading cause of cancer death in women in the USA. The majority of malignant tumors of the ovary are diagnosed at an advanced stage, making it the most fatal gynecological cancer. The aim of the current study was to determine whether there are differences in immunohistochemical tissue staining of cytokine tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) between benign tumors and malignant primary ovarian cancer. In total, 28 patients undergoing surgery for ovarian cysts were evaluated, and a diagnosis of benign neoplasm (n=14) or malignant neoplasm (n=14) was determined. An immunohistochemical study of histological sections of ovarian tumors was conducted. The results were analyzed using Fisher's exact test, with P<0.05 indicating a statistically significant difference. Immunohistochemical staining of IL-10 was increased in malignant tumors compared with benign tumors (P=0.0128). For TNF-α, the immunohistochemical staining was more intense in malignant neoplasms, however, a statistically significant difference was not observed. These results indicate that the analysis of cytokines may be useful as a potential tissue marker of ovarian malignancy.

    Background This manuscript evaluates whether specific symptoms, a symptom index (SI), CA125 and HE4 can help identify women with malignant tumors in the group of women with adnexal masses previously diagnosed with ultrasound. Methods This was a cross-sectional study with data collection between January 2010 and January 2012. We invited 176 women with adnexal masses of suspected ovarian origin, attending the hospital of the Department of Obstetrics and Gynecology of the Unicamp School of Medicine. A control group of 150 healthy women was also enrolled. Symptoms were assessed with a questionnaire tested previously. Women with adnexal masses were interviewed before surgery to avoid recall bias. The Ward Agglomerative Method was used to define symptom clusters. Serum measurements of CA125 and HE4 were made. The Risk of Ovarian Malignancy Algorithm (ROMA) was calculated using standard formulae. Results Sixty women had ovarian cancer and 116 benign ovarian tumors. Six symptom clusters were formed and three specific symptoms (back pain, leg swelling and able to feel abdominal mass) did not agglomerate. A symptom index (SI) using clusters abdomen, pain and eating was formed. The sensitivity of the SI in discriminating women with malignant from those with benign ovarian tumors was 78.3%, with a specificity of 60.3%. Positive SI was more frequent in women with malignant than in women with benign tumors (OR 5.5; 95% CI 2.7 to 11.3). Elevated CA125 (OR 11.8; 95% CI 5.6 to 24.6) or HE4 (OR 7.6; 95% CI 3.7 to 15.6) or positive ROMA (OR 9.5; 95% CI 4.4 to 20.3) were found in women with malignant tumors compared with women with benign tumors. The AUC-ROC for CA125 was not different from that for HE4 or ROMA. The best specificity and negative predictive values were obtained using CA125 in women with negative SI. Conclusion Women diagnosed with an adnexal mass could benefit from a short enquiry about presence, frequency and onset of six symptoms, and CA125 measurements. Primary care

    Primary ovarian insufficiency is one of the main causes of female infertility owing to an abnormal ovarian reserve. Its relevance has increased in more recent years due to the fact that age of motherhood is being delayed in developed countries, with the risk of having either primary ovarian insufficiency or less chances of pregnancy when women consider the option of having their first baby. Several exogenous factors can lead to this event, such us viral infections, metabolomic dysfunction, autoimmune diseases, and environmental or iatrogenic factors, although in most cases the mechanism that leads to the disorder is unknown. Genetic factors represent the most commonly identified cause and the impact of sex chromosome abnormalities (e.g., Turner syndrome or X structural abnormalities), autosomal and X-linked mutations on the genesis of primary ovarian insufficiency has also been well described. Yet in most cases, the genetic origin remains unknown and there are multiple candidate genes. This review aims to collect all the genetic abnormalities and genes associated with syndromic and non syndromic primary ovarian insufficiency that have been published in the literature to date using the candidate-gene approach and a genome-wide analysis.

    Papillary serous adenocarcinoma has been recognized as a highly malignant ovarian cancer and is also not uncommonly seen in primary lung cancer. Difficulty may exist in determining the origin of the primary tumor in women with synchronous pulmonary and ovarian tumors. We present a patient who was initially diagnosed and treated as stage IV papillary serous ovarian cancer with diffuse pulmonary metastases. Only transient symptomatic improvement was achieved after standard chemotherapy for ovarian cancer, and then she died of respiratory distress during treatment. Poor tumor response to chemotherapy prompted us to reevaluate the previous bronchoscopic biopsy, and immunohistochemical studies, which were cytokeratin (CK) 7 positive, CK20 negative, and thyroid transcription factor-1 (TTF-1)-positive, provided irrefutable evidences for the diagnosis of primary lung cancer. We suggest that in dealing with coexistence of ovarian and pulmonary tumors, immunohistochemical study by using CK7, CK20, and TTF-1 may be helpful in the differentiation of the primary origin.

    To evaluate the prediction of malignancy in women with pelvic masses using the Copenhagen Index (CPH-I) and Risk of Ovarian Malignancy Algorithm (ROMA). Three hundred eighty four women operated due to an ovarian mass were enrolled between January 2010 and June 2015. All patients had histopathological diagnosis, HE4 and CA125 measurement. CPH-I and ROMA were calculated and their performances compared in two distinct scenarios: 1) for the discrimination of benign ovarian disease from epithelial ovarian cancer (EOC), non-epithelial ovarian cancer, borderline ovarian tumors (BOT) and ovarian metastases, and 2) for the discrimination of benign disease from EOC. Receiver Operator Characteristics' Areas Under the Curves (AUC) were calculated for CPH-I and ROMA and compared. Of the 384 women, 224 presented a benign ovarian tumor, 32 BOT, 87 EOC, 26 non-epithelial ovarian cancer, and 15 had ovarian metastases. The best AUCs were obtained for the discrimination of EOC from benign tumors. CPH-I performed slightly better than ROMA, and both approached 89% sensitivity and 85% specificity. When all malignant tumors (EOC, BOT, ovarian metastases and non-epithelial ovarian cancer - entire cohort) were included, the performance of CPH-I and ROMA declined to nearly 72%, although the specificity remained close to 85%. CPH-I and ROMA performed similarly well for the discrimination of EOC from benign ovarian tumors. However, caution is necessary since, in practical situations, where all the histological possibilities for malignant ovarian tumors must be considered, the sensitivity of CPH-I and ROMA may not surpass 70%.

    Although some studies have reported a potential connection between ovulation induction therapy (OIT) and malignant ovarian diseases, the results have been inconclusive. In the present study, we sought to determine whether women undergoing OIT at our in vitro fertilization (IVF) clinic, especially those with severe ovarian hyperstimulation syndrome (OHSS) and suspicious cytologic findings, were at risk for developing malignant ovarian tumours after treatment. Patients who underwent OIT at our IVF clinic were enrolled in this study and assessed for any evidence of malignant ovarian tumours. Patients who developed severe OHSS as a result of OIT were treated with a culdocentesis. Cells from the ascitic fluid were cytologically scored for abnormality and malignancy. Peripheral blood samples were obtained from patients with severe OHSS to determine serum levels of the tumour markers (CA-125 and HE4) that were used to calculate the Risk for Ovarian Malignancy Algorithm (ROMA) index. Follow-up data were available for 1,353 of the 1,587 patients (85%) who underwent OIT at our IVF clinic between January 2006 and December 2012. Twenty-three patients (1.4%) were hospitalized with OHSS. Culdocentesis was performed 16 times in nine patients with severe OHSS (age range, 23-34 years; mean, 27.1 years). Although cytological examination of the ascitic cells of these patients suggested malignant ovarian neoplasia, over the course of the observation period, the ovarian volume gradually decreased and became normal. Subsequent cytological and histological examinations failed to find evidence of any malignant tumours in these nine patients. None of the 1,353 participants who underwent OIT developed any malignant ovarian tumours during the study period. Moreover, none of the 462 patients who were in our ovarian tumour registry were also participants in the IVF program. The presence of atypical cells in the ascitic fluid of women with severe OHSS does not likely indicate malignancy

    Primary malignancies of the heart and pericardium are rare. All the available data come from autopsy studies, case reports, and, in recent years, from large, specialized, single-center studies. Nevertheless, if primary malignancy is present, it may have a devastating implication for patients. Malignancies may affect heart function, also causing left-sided or right-sided heart failure. In addition, they can be responsible for embolic events or arrhythmias. Today, with the widespread use of noninvasive imaging modalities, heart tumors become evident, even as an incidental finding. A multimodality imaging approach is usually required to establish the final diagnosis. Despite the increased awareness and improved diagnostic techniques, clinical manifestations of primary malignancy of the heart and pericardium are so variable that their occurrence may still come as a surprise during surgery or autopsy. No randomized clinical trials have been carried out to determine the optimal therapy for these primary malignancies. Surgery is performed for small tumors. Chemotherapy and radiation therapy can be of help. Partial resection of large neoplasms is performed to relieve mechanical effects, such as cardiac compression or hemodynamic obstruction. Most patients present with marginally resectable or technically nonresectable disease at the time of diagnosis. It seems that orthotopic cardiac transplantation with subsequent immunosuppressive therapy may represent an option for very carefully selected patients. Early diagnosis and radical exeresis are of great importance for long-term survival of a primary cardiac malignancy. This can rarely be accomplished, and overall results are very disappointing. © 2014 Wiley Periodicals, Inc.

    Long noncoding RNA (lncRNA) has been recognized as a regulator of gene expression, and the dysregulation of lncRNAs is involved in the progression of many types of cancer, including epithelial ovarian cancer (EOC). To explore the potential roles of lncRNAs in EOC, we performed lncRNA and mRNA microarray profiling in malignant EOC, benign ovarian cyst and healthy control tissues. In this study, 663 transcripts of lncRNAs were found to be differentially expressed in malignant EOC compared with benign and normal control tissues. We also selected 18 altered lncRNAs to confirm the validity of the microarray analysis using quantitative real-time PCR (qPCR). Pathway and Gene Ontology (GO) analyses demonstrated that these altered transcripts were involved in multiple biological processes, especially the cell cycle. Furthermore, Series Test of Cluster (STC) and lncRNA-mRNA co-expression network analyses were conducted to predict lncRNA expression trends and the potential target genes of lncRNAs. We also determined that two antisense lncRNAs (RP11-597D13.9 and ADAMTS9-AS1) were associated with their nearby coding genes (FAM198B, ADAMTS9), which participated in cancer progression. This study offers helpful information to understand the initiation and development mechanisms of EOC. PMID:27941916

    2015-01-01

    Objective: To evaluate the ability of dynamic post-contrast sequence to specify indeterminate ovarian masses with inconclusive MR features of malignancy. Since management is dramatically different, special focus on the ability to differentiate borderline from invasive malignancy was considered. Methods: 150 ovarian masses were detected by pelvic ultrasound in 124 patients. Masses had been considered for dynamic post-contrast MRI. We expressed the kinetic parameters (i.e. enhancement amplitude, time peak of maximal uptake and maximal slope) in the form of maximum relative enhancement percentage (MRE%), time of maximal peak of contrast uptake (Tmax) and slope enhancement ratio (SER) curves. Histological findings were the gold standard of reference. Results: Malignant ovarian masses showed higher MRE% than benign and borderline masses (p < 0.001). Tmax was shorter for malignant than benign (p < 0.01) and borderline (p < 0.001) ovarian masses. SER curves were the most suggestive of malignancy with a specificity and accuracy of 85.7% and 84.7%, respectively. Conclusion: Dynamic contrast-enhanced MRI could be a specific sequence to differentiate ovarian masses with indeterminate MR morphology with a special discrimination for low potential from invasive ovarian malignancy. Advances in knowledge: The study evaluated the diagnostic performance of the individual parameters of dynamic post-contrast MR sequence in evaluating ovarian masses. Management divert between benign, borderline and invasive malignant masses; our work presented a cut-off value for the peak of contrast uptake of 120%, which helped in the differentiation between benign and malignant tumours; the SER curves with Type III (early washout) pattern that was indicative of invasive malignancy was more specific than borderline malignancy.

    To describe new cases of primary malignancy arising around dental implants. Three patients presented with asymptomatic lesions around longstanding dental implants that resembled peri-implantitis. One case was primary large B-cell lymphoma and the remaining cases were primary squamous cell carcinoma in patients with oral lichen planus. The literature was reviewed for cases mimicking peri-implantitis. Of 42 implant-associated malignancies reported from 2000 through 2014, 85.7% were squamous cell carcinoma (69% primary and 9.4% metastatic). Most patients presented with pre-existing risk factors for oral cancer. Lymphoma was not associated with dental implants. Primary and metastatic malignancies can occur in peri-implant mucosa, often with clinical and radiographic features resembling peri-implantitis. Clinicians should have a high index of suspicion for changes in peri-implant mucosa in patients with existing risk factors; however, rare cases such as lymphoma might present outside this risk population. Histopathologic analysis should be included in the management of selected peri-implant lesions to avoid delayed diagnosis of malignancy.

    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. This work aimed to study DNA ploidy and nuclear area in ovarian serous and mucinous; benign, borderline and malignant tumours. 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. 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. 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.

    Introduction: We evaluated the feasibility of laparoscopic cytoreduction for primary advanced ovarian cancer. Methods: All patients with presumed stage 3/4 primary ovarian cancer underwent attempted laparoscopic cytoreduction. All patients had CT evidence of omental metastasis and ascites. A 5-port (5-mm) transperitoneal approach was used. A bilateral salpingo-oophorectomy, supracervical hysterectomy, and omentectomy were performed with PlasmaKinetic (PK) cutting forceps. A laparoscopic 5-mm Argon-Beam Coagulator was used to coagulate tumor in the pelvis, abdominal peritoneum, intestinal mesentery, and diaphragm. Results: Nine of 11 cases (82%) were successfully de-bulked laparoscopically without conversion to laparotomy. Median operative time was 2.5 hours, and median blood loss was 275 mL. All tumors were debulked to <2 cm and 45% had no residual disease. Stages were 1–3B, 7–3C, and 1–4. Median length of stay was one day. Median VAS pain score was 4 (discomforting). Two of 11 patients (18%) had postoperative complications. Conclusion: Laparoscopic cytoreduction was successful and resulted in minimal morbidity. Because of our small sample size, additional studies are needed. PMID:20529532

    A case of primary malignant lymphoma of the urinary bladder is described. The classic presentation of gross hematuria and dysuria with a benign clinical course is illustrated. From a review of the literature and our experience, we conclude that localized primary lymphoma of the bladder, especially those with favorable histologic findings, often does not require medical or surgical intervention. Persistent irritative bladder symptoms can be palliated adequately with external beam radiotherapy, while surgical intervention is rarely indicated.

    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

    In the Department of Pathology of the Albert Szent-Györgyi Medical University in Szeged during the last 30 years 1770 (19.4% of the cancers) primary malignant lung tumours were observed in autopsy material, from which 86 patients (4.9%) had other malignancies as well. In 81 cases other extrapulmonary and in 5 cases other primary lung tumours were observed. The male predominance in these cases was significant. All of the patients were heavy smokers. Amongst these synchronous tumour-associations the most frequent extrapulmonary tumours arose in the urogenital tract, in the head and neck, relatively frequently also in the breast, liver, stomach, intestine and thyroid. These cases caused diagnostic dilemmas both for the clinician and even for the pathologist. Several signs help to distinguish a new primary tumour from a metastasis. Multiplicity itself does not mean poorer prognosis. Each cancer should possibly receive adequate treatment.

    Abstract 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

    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.

    The aims of this study are to present demographical features of cases diagnosed with malignant tumor associated with ovarian mature teratoma and to analyze histopathological features and clinical follow up of these tumors. Single-institution retrospective charts were reviewed to identify all cases of ovarian mature teratoma diagnosed from 1998 to 2015. Clinicopathological parameters that were analyzed include age, tumor size, tumor stage, histological type, laterality, IOC diagnosis and whether or not patient has received adjuvant chemotherapy. A total of 218 ovarian mature teratoma cases were identified during the study period. Of the 218 ovarian mature teratoma specimens, eight (3.7%) exhibited malignant tumors. The average age for cases of malignancy associated with ovarian mature teratoma was 44.6 years. The average size of tumors was 10.36cm. On final pathology, histological types of tumors were as follows: two cases each of squamous cell carcinoma and papillary thyroid carcinoma; one case each of mucinous adenocarcinoma, metastatic adenocarcinoma, sebaceous carcinoma and oligodendroglioma. Only one patient with Stage IIB tumor died of disease. One patient was alive with metastatic disease two months after initial diagnosis. Mean and median follow-up times were 64.1 and 49 months, respectively. An ovarian mass that has characteristics of a teratoma in a postmenopausal patient should alert for malignancy -regardless of tumor size. IOC is a valuable tool for the detection of malignancy and should be requested to determine the modality of surgical approach. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Multiple primary malignancy was reported firstly by Billroth in 1889. Recently, multiple primary malignancies are considered to increase due to improved survival rate of cancer patients, advanced diagnostic tools, and increased use of chemotherapy and radiotherapy. In Korea, several cases of triple primary malignancies were reported. However, four primary malignancies in gastro-intestinal tract was rarely reported. Recently, we experienced a 70 year-old male who was diagnosed with metachronous four primary malignancies in rectum, ascending colon, stomach, and ampulla of Vater. We report this rare case of metachronous four primary malignancies with a review of literature.

    The aim of the present study was to investigate the role of epigenetic inactivation of the runt-related transcription factor 3 gene (RUNX3) in the malignant transformation of ovarian endometriosis. Samples obtained by microdissection and scraping included 30 malignant ovarian endometriotic cyst tissues and 30 corresponding eutopic endometrium tissues from the endometriosis-associated ovarian carcinoma (EAOC) group, 19 benign ovarian endometriotic cyst tissues and 22 corresponding eutopic endometrium tissues from the endometriosis (EM) group and 22 normal eutopic endometrium tissues from the control endometrium (CE) group. RUNX3 methylation status was determined by methylation-specific PCR and bisulfite sequencing, while levels of RUNX3 and ERα protein expression were evaluated using immunohistochemistry. The percentage of RUNX3 methylation and negative RUNX3 protein expression in the malignant ovarian endometriotic cysts from the EAOC group was significantly higher than that in the benign ovarian endometriotic cysts from the EM group. The percentage of RUNX3 methylation and negative RUNX3 protein expression in the eutopic endometrium from the EAOC group was significantly higher than that in the EM and CE groups. An inverse correlation between positive RUNX3 protein expression and methylation was observed and a positive correlation was shown between RUNX3 methylation and ERα protein expression. In the malignant ovarian endometriotic cysts from the EAOC group, there was no significant correlation between methylation frequency of the RUNX3 gene and histological type. However, the percentage of RUNX3 gene methylation was significantly higher in the tissue samples from patients with surgical stage IC EAOC than the percentage in patients with stage IA and IB disease. These results suggest that RUNX3 inactivation by promoter hypermethylation plays a role in the progression of malignant transformation of ovarian EM and is closely related to estrogen metabolism.

    One of the most extraordinary stories in the chronicles of gynecologic cancers has been that of malignant ovarian germ cell tumors. Prior to the mid-1960s, most patients died of disease. Fifty years later, most survive. Precisely because high cure rates are achievable, the concentration over the past decade has been on minimizing toxicity and late effects. The present review focuses on five areas of interest related to the management of malignant ovarian germ cell tumors that highlight the different therapeutic strategies practiced by pediatric and gynecologic oncologists: 1) primary surgery, 2) surgery alone (surveillance) for patients with FIGO stage IA disease, 3) postoperative management of FIGO stage IC-III disease, 4) postoperative management of pure immature teratoma, and 5) postoperative management of metastatic pure dysgerminoma. All of these topics share a common overarching theme: Lessening acute morbidity and late effects of treatment.

    The authors reviewed the original reports of the association of malignant ovarian tumors with cytologically negative pleural and peritoneal effusions, commonly known as Meigs' pseudo-syndrome and challenged the recent attribution of this disease to Demons. They underlined the historical and clinical interest of the reports of Demons and Meigs and concluded that the term pseudo-Meigs' syndrome, and not pseudo-Demons' syndrome, must be used for malignant ovarian lesions with effusions with negative cytology because Demons did not describe a similar syndrome caused by malignant tumors.

    Due to concern that mucinous malignant or borderline ovarian neoplasms (MON) may represent metastatic deposits from appendiceal primaries, gynecologic oncologists routinely perform appendectomy in these cases. However, a multidisciplinary critique of this practice is lacking. The New England Case-Control study database was utilized to compare the effect of prior appendectomy against known risk factors for MON. Pathology and operative reports of local cases of MON were reviewed to estimate the frequency of microscopic mucinous lesions in the appendix. Protein expression patterns among mucinous ovarian, colorectal, and appendiceal cancers were compared by immunohistochemistry. From the New England Case-Control study, 287 cases of MON were compared against 2339 age-matched controls. Prior appendectomy did not reduce the risk of MON (OR 1.28, 95% CI 0.83-1.92, p = 0.23), while prior tubal ligation, parity, and breastfeeding were each protective against MON. Active smoking (OR 2.04, 95% CI 1.48-2.80, p < 0.001) was associated with an increased risk of MON. Among 196 mucinous adnexal tumors, appendectomy did not reclassify any MON as appendiceal in origin. By immunohistochemistry, mucinous ovarian carcinomas tended to be CK7+/CK20-/MUC2-/CDX2-, whereas mucinous colorectal and appendiceal adenocarcinomas were typically CK7-/CK20+/MUC2+/CDX2+, although with some overlap in immunophenotype. Additionally, PAX8 was positive in a subset of MOC and negative in all appendiceal carcinomas. Prior appendectomy is not protective against development of malignant or borderline MON. Routine appendectomy during surgery for MON seldom reveals an unsuspected GI primary in early stage tumors but may aid in final diagnosis in advanced stage cases.

    Fifteen patients with primary intrahepatic biliary malignancy (cholangiocarcinoma in 13, biliary cystadenocarcinoma in two) were examined by computed tomography (CT). The CT features were classified into three types: (A) a well-defined round cystic mass with internal papillary projections, (B) a localized intrahepatic biliary dilatation without a definite mass lesion, and (C) miscellaneous low-density masses. Intraphepatic biliary dilatation was noted in all cases of Types A and B and half of those of Type C; dilatation of extrahepatic bile ducts occurred in 4/4, 1/3, and 0/8, respectively. CT patterns, such as a well-defined round cystic mass with papillary projections or dilatation of intra- and extrahepatic ducts, give important clues leading to a correct diagnosis of primary intrahepatic biliary malignancy.

    This study was undertaken to evaluate the reproductive and oncologic outcomes of patients diagnosed with Ovarian Germ Cell Malignancy (OGCM) who underwent fertility preserving surgery and adjuvant chemotherapy treated in Gynaecology Oncology Unit, Sultanah Bahiyah Hospital, Kedah, Malaysia. We retrospectively reviewed 33 patients who had fertility preserving surgery and adjuvant chemotherapy in our center from 2000 - 2010. Gynaecology oncology record and histopathology database were reviewed. Patients were contacted, assessed and interviewed via telephone using standardized questionnaire to assess their menstrual, reproductive function and disease status after treatment, post therapeutic status of pregnancy or delivery and overall survival. Thirty three patients diagnosed with OGCM underwent unilateral salphingo oophorectomy and staging surgery followed by adjuvant chemotherapy (BEP regimen). The mean age at presentation was 19.8 years (range, 9 -34 years). Histological subtypes were 21.2% dysgerminoma, 21.2% immature teratoma, 42.4% yolk sac tumour and 15.2% mixed germ cell tumour. After treatment, 71.4% resumed their menstrual cycles within 6 months. During follow up, 5 patients conceived with 5 live birth deliveries and 3 miscarriages (3 patients had two pregnancies). The overall survival rate was 87.9% with median follow up of 45.2 months. 30.3% of patient had disease recurrence with median disease free interval of 5 months while 6.0% had disease progression despite of adjuvant chemotherapy. One of the most important adverse prognostic factors for recurrence and disease progression is Yolk sac tumour (non DSG/IMT) histotype. Fertility preserving surgery and adjuvant chemotherapy appear to have little effect on fertility and menstrual cycle with a good overall survival. Patients diagnosed with histopathological yolk sac tumour element had poor outcome and perhaps need more aggressive and longer adjuvant therapy.

    Ovarian malignant mixed mullarian tumor (OMMMT) is a rare and aggressive tumor of the female genital tract, occurring mainly in elderly women. Stage of disease is the most important predictor for survival with no prognostic effect, yet, of heterologous elements. Rare case reports described the peculiar presence of primitive neuroectodermal tissue among other heterologous elements in these tumors. Attractive designations, such as teratoid carcinosarcoma, were set by some authors to describe this subset of lesions, where it was considered a primary neuroectodermal tumor capable of multilineage differentiation. We here report a case of OMMMT in an elderly woman with focal primitive neuroectodermal differentiation as the sole heterologous element, and review the controversy on this topic in the literature.

    Leiomyomas are benign neoplasms that can develop wherever smooth muscle is present. Primary leiomyomas of the ovary originate from smooth muscle cells of ovarian tissue and are rare, solitary tumors. Approximately 70 cases have been reported. They usually present in premenopausal women. The present case is a report of left ovarian leiomyoma in a postmenopausal woman.

    Primary malignant tumors of the small bowel are uncommon and are often diagnosed at an advanced stage. A 10 year survey (1967 to 1977) of the clinical records at one hospital revealed 39 cases of primary malignant tumors of the small bowel. The most common symptoms were abdominal pain (89.7 percent) and weight loss (77 percent). Six patients presented with complications of enterovesical fistula, bleeding and perforation. Preoperative diagnosis was suspected in 27 cases (69.2 percent). Adenocarcinoma was the most common tumor, followed by carcinoid tumor, lymphoma, leiomyosarcoma and melanoma. The treatment of choice was surgical resection whenever possible. Curative resection was attempted in 25 cases. Adjuvant radiotherapy and chemotherapy was used in four patients with lymphoma. Twenty-seven patients (69.2 percent) are alive from 1 to 6 years after diagnosis and treatment. The 5 year survival rate is 35 percent. Earlier diagnosis is essential if the prognosis for patients with small bowel malignancy is to be improved.

    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.

    To characterize primary malignant cardiac tumors operated on in our center and to analyze patient survival. Between January 1994 and August 2014, 123 patients with cardiac tumors underwent surgery, of which 12 (9.8%) were primary malignant tumors - eight sarcomas (67%), three B-cell lymphomas (25%) and one epithelioid hemangioendothelioma (8.3%). The tumor affected the left atrium in five cases (42%), the right atrium in four (33%), the right ventricle in two (17%) and the pulmonary valve in one (8%). Patients' mean age was 55.4 ± 16.9 years, 67% were female and 75% presented in New York Heart Association class III-IV. Resection was complete (negative margins) in five cases and partial in seven (five sarcomas and two lymphomas), and 11 patients needed adjuvant therapy, surgery alone being curative in only one (epithelioid hemangioendothelioma). Mean follow-up was 41.7 ± 61.3 months: 24.8 ± 30.0 months (3.8-95.7) for sarcomas, 70.1 ± 118.0 months (1-206.3) for lymphomas and 91.9 months for the epithelioid hemangioendothelioma. During follow-up, 10 patients died (83%) and two were alive (17%). Overall survival at 30 days, six months, one year and two years was 91.7%, 66.7%, 58.3% and 41.7%, respectively. In the sarcoma group, 1-year and 2-year survival were 62.5% and 37.5%, respectively. Resection of primary malignant cardiac tumors, even partial, is safe, provides relief of obstructive symptoms and improves quality of life, but is rarely curative and has a low survival rate. Due to the rarity of such tumors, a multicenter database could improve knowledge and help clarify the indications for cardiac surgery as a treatment option.

    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

    The frequency and causes of ovarian failure among 182 long-term survivors of childhood cancer were examined. Twenty-two patients (12%) had ovarian failure. Ovarian failure was found in 17 of 25 patients (68%) who had both ovaries within abdominal radiotherapy fields, in five of 35 patients (14%) whose ovaries were at the edge of the treatment field, and in none of 122 patients with one or both ovaries outside of an abdominal treatment field. Covariate and multivariate analyses of tumor type, age at diagnosis, duration of follow-up, abdominal tumor surgery, abdominal radiotherapy, number of chemotherapeutic agents administered, and cumulative doses of several drugs revealed that the location of the ovaries relative to radiation treatment fields was the only risk factor for subsequent ovarian failure.

    Most clinicians are not prepared to provide integrated personal care to address all the clinical needs of women with primary ovarian insufficiency. Design thinking is an engineering methodology used to develop and evaluate novel concepts for systems operation. Here we articulate the need for a seamlessly integrated mobile health system to support genomic research as well as patient care. We also review the pathophysiology and management of primary ovarian insufficiency. Molecular understanding regarding the pathogenesis is essential to developing strategies for prevention, earlier diagnosis, and appropriate management of the disorder. The syndrome is a chronic disorder characterized by oligo/amenorrhea and hypergonadotropic hypogonadism before age 40 years. There may be significant morbidity due to: 1) depression and anxiety related to the loss of reproductive hormones and infertility; 2) associated autoimmune adrenal insufficiency or hypothyroidism; and 3) reduced bone mineral density and increased risk of cardiovascular disease related to estrogen deficiency. Approximately 5% to 10% of women with primary ovarian insufficiency conceive and have a child. Women who develop primary ovarian insufficiency related to a premutation in FMR1 are at risk of having a child with fragile X syndrome, the most common cause of inherited intellectual disability. In most cases of spontaneous primary ovarian insufficiency no environmental exposure or genetic mechanism can be identified. As a rare disease, the diagnosis of primary ovarian insufficiency presents special challenges. Connecting patients and community health providers in real time with investigators who have the requisite knowledge and expertise would help solve this dilemma.

    Alterations in p16 protein expression have been reported to be associated with tumor development and progression. However, p16 expression status in the peritumoral stroma has been rarely investigated. We investigated the stromal p16 expression in ovarian neoplasms using immunohistochemistry, and differences in the expression status depending on the degree of malignancy and histological type were analyzed. This study included 24, 21, and 46 cases of benign, borderline, and malignant ovarian lesions, respectively, of which 29, 25, and 32 cases were serous, mucinous, and endometriosis-associated lesions. Most benign lesions showed negative or weak expression, whereas borderline lesions showed focal, moderate expression. Malignant lesions showed markedly elevated stromal p16 expression compared with benign or borderline lesions. There were significant differences in stromal p16 expression between benign and borderline lesions (P < 0.001) and between borderline and malignant lesions (P < 0.001). These significances remained when analysis was performed based on lesion classification as serous, mucinous, and endometriosis-associated. In contrast, differences in stromal p16 expression among the histological types were not significant. Stromal p16 expression in ovarian neoplasms was absent or weak in benign and focal, moderate in borderline lesions, whereas malignant lesions exhibited diffuse, moderate-to-strong p16 immunoreactivity. Our observations suggest that stromal p16 expression is involved in the development of ovarian carcinoma. Further studies are necessary to confirm our preliminary results. PMID:27572321

    A case of a primary malignant mesenchymoma of the lung with elements of rhabdomyo-, leiomyo-, osteo-, fibro- and lipo-sarcoma is described. The tumor developed in a man of 58 with a long history of smoking, complaints of chest pains and cough with scanty sputum expectoration. The neoplastic process involved the upper lobe of the left lung and microscopically contained smooth muscle, endothelial, fibroblast-like cells, multinuclear giant cells resembling osteoclasts, strips of osteoid-like hyalinized connective tissue. Electron-microscopic examination revealed myoid-type cells with clusters of myofilaments and Z-type material, cells resembling fibroblasts, osteoclasts and lipocytes. It is suggested that there should be a common histogenesis of primary lung sarcomas arising from a stem cell precursor of mesenchymal origin in lung stroma, bronchial and vascular walls, pleura.

    Some women suffering from leukemia require bone marrow transplantation to be cured. Bone marrow transplantation is associated with a high risk of sterility, and some patients are offered fertility preservation by cryopreservation of the ovarian cortex. Transplantation of the ovarian cortex to women cured of leukemia who became menopausal is currently not performed because of the risk of introducing the disease. In this study, individual pieces of ovarian cortex intended for reimplantation from 25 patients with leukemia were transplanted to each of 25 nude mice for 20 weeks. The ovarian cortex was examined before and after transplantation by histology and immunohistochemistry, and RT-quantitative PCR (in the 7 patients with a known marker). Seventeen patients had the ovarian cortex retrieved when they were in complete remission. Before transplantation, 4 of 7 pieces (2 from patients in complete remission) of ovarian cortex had a positive RT-quantitative PCR. After transplantation, none of the mice revealed any sign of disease, neither in the pieces of ovarian cortex transplanted nor in any of the murine organs evaluated. Thus, the ovaries from patients in complete remission do not appear to contain viable malignant cells contrasting ovarian tissue retrieved before treatment.

    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.

    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

    Amplification of HER-2 gene and overexpression of HER-2 receptor play a significant role in the progression of a number of malignancies such as breast cancer. Trastuzumab (anti-HER-2 therapeutic agent) has been used successfully in treatment of breast cancer. The aim of this study was to assess the pattern of HER-2 gene amplification and of HER-2 receptor expression in a spectrum of serous and mucinous ovarian tumors to determine whether HER-2 is altered in these neoplasms similar to that occurring in breast cancer. Formalin-fixed paraffin-embedded microarray tissue sections from 212 specimens were stained with HER-2 antibody using immunohistochemistry and with anti-HER-2 DNA probe using chromogenic in situ hybridization. Specimens consisted of 65 benign tumors (50 serous and 15 mucinous), 26 borderline (13 serous and 13 mucinous), 73 malignant (53 serous carcinoma and 20 mucinous carcinoma), 18 metastatic deposits (13 serous and 5 mucinous), in addition to 30 normal tissues (16 ovarian surface and 14 normal fallopian tube). HER-2 protein-positive expression was not detected in the normal or the benign tissues. Borderline neoplasms showed positive staining, but no overexpression. HER-2 overexpression was seen only in 4 carcinoma specimens: 1/53 (1.8%) primary serous carcinomas and 3/20 (15%) primary mucinous carcinomas. HER-2 gene amplification was seen in 4 specimens: 2 primary mucinous carcinomas and 2 malignant deposits of these 2 mucinous carcinomas. In conclusion, alteration of HER-2 was not detected in ovarian serous neoplasms; however, in mucinous carcinoma, HER-2 amplification and overexpression occur more frequently.

    Solid pseudopapillary neoplasm occurring as a primary tumor outside the pancreas is a rare event. We report a case of an ovarian primary occurring with an ill-defined cystic mass in a 39-year-old woman. The morphologic and immunohistochemical features of the ovarian neoplasm described in this report are compatible with those of solid pseudopapillary neoplasm of the pancreas. Histologically, the tumor cells of the case we report infiltrate into the ovarian parenchyma. Because of the diagnosis is not clear before surgery, the patient had a reoccurrence two months after the operation in which laparoscopic simple ovarian cystectomy and part ovarian tissue removal, followed by the right salpingo-oophorectomy. The case herein confirms that solid pseudopapillary neoplasm of the ovary belongs to the class of low-grade malignant tumor with certain invasiveness. The diagnosis should be taken into serious consideration in order to avoid missed diagnosis and delay treatment. Through this case we have a better understanding of the biological behavior of solid pseudopapillary neoplasm of the ovary. PMID:26339451

    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.

    Although undifferentiated tumors are the most lethal among all ovarian cancer histotypes, the exact reasons for this situation are unclear. This report was aimed at investigating whether the high aggressiveness of undifferentiated ovarian cancer may be associated with a biochemical composition of malignant ascites accumulating in the peritoneal cavity. We analyzed ascites from patients with undifferentiated, high-grade serous, endometrioid and clear-cell ovarian cancers, and from non-cancerous patients with respect to a group of soluble agents involved in cancer cell progression. Moreover, the effect of these fluids on proliferation and migration of ovarian cancer cells (A2780, OVCAR-3 and SKOV-3) was evaluated. The study showed that the level of all tested proteins in malignant ascites was higher than in the benign fluids. Concentration of 9/11 agents (CCL2, CXCL1, CXCL5, CXCL8, CXCL12, HGF, PAI-1, TGF-β1 and VEGF) was the greatest in the fluids from undifferentiated cancer, while the level of remaining 2 (IL-6 and uPA) was the highest in ascites from serous carcinoma. Proliferation of cancer cells was the most effective when they were subjected to ascites from patients with undifferentiated and serous cancer, whereas the migration was the highest in the case of undifferentiated tumors. Our findings indicate that the aggressiveness of undifferentiated ovarian tumors may be associated with the composition of malignant ascites, in particular the concentration of specific proinflammatory, cancer-promoting agents.

    Ovarian cancer is the seventh most common cancer in women and the most frequent cause of gynaecological malignancy-related mortality in women. Currently, no standardized reliable screening test exists. MicroRNA profiling has allowed the identification of signatures associated with diagnosis, prognosis and response to treatment of human tumours. The aim of this study was to determine if a microRNA signature could distinguish between malignant and benign ovarian disease. A training set of 5 serous ovarian carcinomas and 5 benign serous cystadenomas were selected for the initial experiments. The validation set included 20 serous ovarian carcinomas and 20 benign serous cystadenomas. The serum/plasma focus microRNA Exiqon panel was used for the training set. For the validation set a pick and mix Exiqon panel, which focuses on microRNAs of interest was used. A panel of 4 microRNAs (let-7i-5p, miR-122, miR-152-5p and miR-25-3p) was significantly down regulated in cancer patients. These microRNAs target WNT signalling, AKT/mTOR and TLR-4/MyD88, which have previously been found to play a role in ovarian carcinogenesis and chemoresistance. let-7i-5p, miR-122, miR-152-5p and miR-25-3p could act as diagnostic biomarkers in ovarian cancer.

    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

    Currently no treatment has proved successful in inducing ovarian steroidogenic and/or gametogenic recovery in patients with haematological malignancies treated by cytotoxic chemotherapy once biochemical failure becomes manifest i.e., when FSH levels exceed 40 IU/L. This paper reports two such cases with classical biochemical ovarian failure in which ovarian function was induced by brief stimulation with Human Menopausal Gonadotrophin (HMG).

    We report a case of primary intracranial malignant melanoma (PIMM) with extracranial metastases. The patient was an 82-year-old woman diagnosed with PIMM under the left cerebellar tentorium. We performed a tumor resection followed by gamma knife surgery. An magnetic resonance imaging at 11 months after surgery showed a local intracranial recurrence. At 12 months, vertebral metastasis was suspected, and 2-[fluorine-18]-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (FDG-PET/CT) showed multiple extracranial metastases. She died at 13 months after surgery. Although extracranial metastases of PIMM are extremely rare, we should carefully follow up extracranial metastases together with intracranial ones, especially by FDG-PET/CT, even at an early asymptomatic stage.

    We sought to report incidence, risk factors, and survival related to bowel obstruction in 311 ovarian cancer patients with recurrent disease. A total of 68 (22%) had a documented bowel obstruction during their cancer course, and 49 (16%) developed it after cancer recurrence. Surprisingly, 142 (45%) fit into an "unknown" category (3+ months of data lacking from last contact/death). No risk factors were identified; management included surgery (n = 21), conservative measures (n = 21), and other (n = 7). Documented bowel obstruction was not associated with a statistically significant reduction in survival after cancer recurrence. In conclusion, although bowel obstruction occurs in only a subgroup of patients with ovarian cancer and does not appear to detract from survival after cancer recurrence, limited end-of-life information may be resulting in an underestimation of incidence.

    The purpose of this study is to investigate if female patients with lymphoma demonstrate diminished ovarian reserve prior to initiation of the lymphoma treatment. Sixty-four patients with newly diagnosed lymphoma undergoing controlled ovarian hyperstimulation for fertility preservation were compared with 365 healthy controls undergoing elective oocyte cryopreservation (controlled ovarian hyperstimulation (COH)) and 128 patients with other types of malignancy prompting fertility preservation. The data of all lymphoma patients, all elective, and all the patients with other types of malignancy who met the inclusion criteria and underwent COH for fertility preservation during the study period were retrospectively analyzed. Primary outcomes included serum anti-Müllerian hormone (AMH) levels (ng/mL) and antral follicle count (AFC). Patients in the lymphoma group demonstrated significantly lower AMH levels and AFC and had less oocytes harvested and cryopreserved when compared to healthy controls as well as patients with other malignancies. Patients with lymphoma demonstrate diminished ovarian reserve when compared with healthy controls and patients with other malignancies. This should be taken into consideration when deciding on the dose for COH.

    Primary malignant melanoma (MM) accounts for 1% of all cancers, and only 3% to 7% of these tumors occur in the female genital tract. Data are limited with respect to the basis for treatment recommendations because of the rarity of MM. The overall prognosis of melanomas of the female genital tract is very poor. Two cases of MM of the female genital tract are presented. The first case is of a 70-year-old female patient who complained of left thigh pain and underwent magnetic resonance imaging that showed cervical cancer with involvement of the vagina, bladder, and parametrium, in addition to multiple bony metastases of the proximal femur, acetabulum, and both iliac bones. The second case is of a 35-year-old female patient who suffered from vaginal bleeding for 5 months, and she was diagnosed as having primary vaginal melanoma. The patient underwent radical surgery and two additional surgeries because of recurrence of cancer in both inguinal areas. After surgery, the patient received adjuvant immunotherapy, radiation therapy, and chemotherapy. In both the aforementioned cases, the pathologic diagnosis was made after immunohistochemical analysis, i.e., the tumor cells were stained with HMB-45 and S100, and were found to be positive for both immunostains.

    Neurensin-2 (NRSN2) is a 24KD protein, which is reported located in the membrane, while its biological functions remain unknown, not to mention in the field of tumor biology. In current study, we aimed to analyze the functions of NRSN2 in ovarian cancer. We screened TCGA database and surprisingly found that its copy number and mRNA level are gained and heightened respectively in parts of serous ovarian cancer patients. In current study, both loss- and gain- function assays found that NRSN2 is associated with the malignant phenotype in ovarian cancer cells, because NRSN2 plays a remarkable role in anchorage-independent colony formation, subcutaneous tumor formation, cell invasion, and chemoresistance. Furthermore, we found that the level of NRSN2 was positively correlated with the expression of stem cell marker CD133. In addition, Wnt canonical signaling and Twist/Akt/Erk axis were also regulated by NRSN2. In conclusion, we found that a poorly studied protein, NRSN2, which is associated with the malignant phenotype of serous ovarian cancer and as a membrane protein; it could be a target for serous ovarian cancer treatment.

    Rectal perforation is uncommon in ovarian cancer, even in advanced stages. Pure primary ovarian squamous cell carcinoma is a very rare subtype of ovarian cancer and has not been reported to cause rectal perforation. A 50-year-old woman presented with rectal bleeding. Rectosigmoidoscopy suggested perforation of a pelvic tumor into the rectum. Abdominopelvic magnetic resonance imaging revealed a 9 cm heterogeneous mass in the pouch of Douglas. We performed complete cytoreduction, including an en-bloc resection of the tumor and rectosigmoid colon. Histopathology showed squamous cell carcinoma of the left ovary penetrating the rectal wall. A common symptom of rectal bleeding was caused by a very rare entity of ovarian cancer penetrating the rectal wall, but thorough evaluation led to its accurate diagnosis and appropriate treatment.

    Reimplantation of cryopreserved ovarian tissue (OT) can successfully restore ovarian function in young cancer patients after gonadotoxic treatment. However, for patients with leukaemia, there is a risk of malignant cell transmission. Our objective was to evaluate minimal disseminated disease in OT from leukaemia patients and test a follicle isolation technique to obtain disease-free follicle suspensions. Cryopreserved OT from 12 leukaemia patients was thawed and analysed by histology and long-term xenografting in immunosuppressed mice. In 10 patients, follicles were isolated from OT, and polymerase chain reaction (PCR) was performed on tissue, digested ovarian suspensions and isolated follicle suspensions to investigate leukaemic cell presence. Mean patient age was 17·1 years. An average of 3·2 follicles were isolated per mm² of cortex. Xenografting of OT induced leukaemic masses in 2/12 mice. PCR identified leukaemic cell presence in 66% of OT. Malignant cells were also detected in digested ovarian suspensions. However, none of the follicle samples (>2300 follicles tested) showed any malignant cell presence after washing. This study demonstrates that it is possible to recover large numbers of viable follicles from cryopreserved OT of leukaemia patients. All isolated and washed follicle suspensions tested negative for leukaemic cells, giving leukaemia patients genuine hope of fertility restoration. © 2017 John Wiley & Sons Ltd.

    Objective To evaluate the accuracy of contrast-enhanced ultrasonography (CEUS) in differential diagnosis of benign and malignant ovarian tumors. Methods The scientific literature databases PubMed, Cochrane Library and CNKI were comprehensively searched for studies relevant to the use of CEUS technique for differential diagnosis of benign and malignant ovarian cancer. Pooled summary statistics for specificity (Spe), sensitivity (Sen), positive and negative likelihood ratios (LR+/LR−), and diagnostic odds ratio (DOR) and their 95%CIs were calculated. Software for statistical analysis included STATA version 12.0 (Stata Corp, College Station, TX, USA) and Meta-Disc version 1.4 (Universidad Complutense, Madrid, Spain). Results Following a stringent selection process, seven high quality clinical trials were found suitable for inclusion in the present meta-analysis. The 7 studies contained a combined total of 375 ovarian cancer patients (198 malignant and 177 benign). Statistical analysis revealed that CEUS was associated with the following performance measures in differential diagnosis of ovarian tumors: pooled Sen was 0.96 (95%CI = 0.92∼0.98); the summary Spe was 0.91 (95%CI = 0.86∼0.94); the pooled LR+ was 10.63 (95%CI = 6.59∼17.17); the pooled LR− was 0.04 (95%CI = 0.02∼0.09); and the pooled DOR was 241.04 (95% CI = 92.61∼627.37). The area under the SROC curve was 0.98 (95% CI = 0.20∼1.00). Lastly, publication bias was not detected (t = −0.52, P = 0.626) in the meta-analysis. Conclusions Our results revealed the high clinical value of CEUS in differential diagnosis of benign and malignant ovarian tumors. Further, CEUS may also prove to be useful in differential diagnosis at early stages of this disease. PMID:25764442

    Background Advanced ovarian cancer is the leading non-breast gynaecologic cause of malignant pleural effusion. Aim of this study was to assess the efficacy of mitoxantrone sclerotherapy as a palliative treatment of malignant pleural effusions due to ovarian cancer. Methods Sixty women with known ovarian cancer and malignant recurrent symptomatic pleural effusion were treated with chest tube drainage followed by intrapleural mitoxantrone sclerotherapy. Survival, complications and response to pleurodesis were recorded. The data are expressed as the mean ± SEM and the median. Results The mean age of the entire group was 64 ± 11,24 years. The mean interval between diagnosis of ovarian cancer and presentation of the effusion was 10 ± 2,1 months. Eighteen patients (30%) had pleural effusion as the first evidence of recurrence. The mean volume of effusion drained was 1050 ± 105 ml and chest tube was removed within 4 days in 75% of patients. There were no deaths related to the procedure. Side effects of chemical pleurodesis included fever (37–38,5°C) chest pain, nausea and vomiting. At 30 days among 60 treated effusions, there was an 88% overall response rate, including 41 complete responses and 12 partial responses. At 60 days the overall response was 80% (38 complete responses and 10 partial responses). The mean survival of the entire population was 7,5 ± 1,2 months. Conclusions Mitoxantrone is effective in the treatment of malignant pleural effusion secondary to ovarian cancer without causing significant local or systemic toxicity. PMID:15357871

    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. The DWI demonstrated an excellent diagnostic performance in discriminating between benign and malignant ovarian neoplasms, and

    Ovarian cancer is the sixth most common cancer among women worldwide, and mortality rates from this cancer are higher than for other gynecological cancers. This is attributed to a lack of reliable screening methods and the inadequacy of treatment modalities for the advanced stages of the disease. FTIR and Raman spectroscopic studies of formalin-fixed normal, benign, and malignant ovarian tissues have been undertaken in order to investigate and attempt to understand the underlying biochemical changes associated with the disease, and to explore the feasibility of discriminating between these different tissue types. Raman spectra of normal tissues indicate the dominance of proteins and lower contents of DNA and lipids compared to malignant tissues. Among the pathological tissues studied, spectra from benign tissues seem to contain more proteins and less DNA and lipids compared to malignant tissue spectra. FTIR studies corroborate these findings. FTIR and Raman spectra of both normal and benign tissues showed more similarities than those of malignant tissues. Cluster analysis of first-derivative Raman spectra in the 700-1700 cm(-1) range gave two clear groups, one corresponding to malignant and the other to normal+benign tissues. At a lower heterogeneity level, the normal+benign cluster gave three nonoverlapping subclusters, one corresponding to normal and two for benign tissues. Cluster analysis of second-derivative FTIR spectra in the combined spectral regions of 1540-1680 and 1720-1780 cm(-1) resulted into two clear clusters corresponding to malignant and normal+benign tissues. The cluster corresponding to normal+benign tissues produced nonoverlapping subclusters for normal and benign tissues at a lower heterogeneity level. The findings of this study demonstrate the feasibility of Raman and FTIR microspectroscopic discrimination of formalin-fixed normal, benign, and malignant ovarian tissues.

    Intravenous and intraperitoneal paclitaxel with S-1 is showing promising results in gastric cancer with peritoneal metastases. We herein report a successful conversion of unresectable to resectable disease using combination chemotherapy with trastuzumab. The patient was a 39-year-old woman with human epidermal growth factor receptor 2-positive gastric cancer with peritoneal, pulmonary and bilateral ovarian metastases. After 6 cycles of S-1 plus cisplatin with trastuzumab, followed by 15 cycles of intravenous and intraperitoneal paclitaxel with S-1 and trastuzumab, the pulmonary and peritoneal metastases exhibited complete response and no evidence of malignancy was found on diagnostic laparoscopy. We performed metastasectomy of the bilateral sizeable ovaries, followed by total gastrectomy. The patient had no recurrence for 16 months after the gastrectomy. Therefore, satisfactory response to systemic and intraperitoneal chemotherapy may convert unresectable to resectable disease, and primary tumor resection with ovarian metastasectomy may prolong survival. This combination chemotherapy has the potential of becoming a conversion therapy for gastric cancer with peritoneal metastases, even if ascites and ovarian metastases are extensive. PMID:28105352

    To describe the clinical and pathologic features of vaginal melanoma and to determine predictors of outcome in patients with this disease. Thirty-seven women with clinical and radiographic stage I vaginal melanoma treated at one institution between 1980 and 2009 were included in this retrospective study. Treatment modalities were assigned to one of three categories: pelvic exenteration, wide excision, and nonsurgical (primary radiation therapy, chemotherapy, or both). Overall survival and progression-free survival were calculated from the date of the surgical diagnosis. The median age was 60.6 years. Eighty-four percent of patients were white. Vaginal bleeding was the most common presenting symptom. Lesions were located in the distal third of the vagina in the majority (65%) of patients. Initial management included a wide local or radical excision (76% of patients); pelvic exenteration (14%); and radiotherapy, chemotherapy, or radiotherapy and chemotherapy (10%). At a median follow-up of 17.4 months, 33 women experienced disease recurrence. Recurrence was local only in seven patients (22%), distant only in 20 (63%), and both in five (15%). The most common sites of distant recurrence were lungs and liver. Median progression-free survival was 11.4 months, and median overall survival was 19 months. The 5-year progression-free and overall survival rates were 9.5% and 20.0%, respectively. Patients treated surgically had significantly longer survival than those treated nonsurgically (P=.01). Radiotherapy after wide excision reduced local recurrence risk and increased survival from 16.1 months to 29.4 months, although the increase was not significant (P=.46). Malignant vaginal melanoma, even when localized at presentation, has a very poor prognosis. Patients treated surgically have longer survival than those treated nonsurgically. Radiotherapy after wide excision reduces local but not distant recurrences.

    Carcinoid tumors are rare neuroendocrine malignancies that typically originate from the gastrointestinal tract. Patients who are diagnosed with carcinoid heart disease generally have poor prognoses because of advanced metastases during staging and few therapeutic options. We present the case of a 61-year-old woman with right-sided heart failure, secondary to carcinoid heart disease caused by a primary ovarian carcinoid tumor. After undergoing surgical resection of the left ovary and fallopian tube, the patient experienced complete resolution of her heart failure symptoms. In addition to the patient's case, we discuss the diagnosis, nature, and treatment of this rare condition.

    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.

    Parenteral nutrition (PN) in patients with disseminated ovarian cancer remains controversial. The role of PN in providing nutrition and improving quality of life is unclear. The present study aimed to determine the pattern of prescribing in a large teaching hospital, and to identify subgroups where the use of PN was justified. Sixty-five patients with advanced ovarian carcinoma received PN between January 2002 and May 2008. A retrospective case note review was undertaken to retrieve data on PN prescribing and outcomes in terms of duration of PN provision, complications, and survival. Three subgroups were identified. Group I consisted of 18 (28%) patients who received PN for a median [interquartile range (IQR)] of 5 (2-11) days. The majority of these 18 patients (n = 13, 72%) had disease-related terminal bowel obstruction. Out of 18 of these patients, 17 (95%) had poor performance status. The median (IQR) survival was 12 (6-28) days. Group II consisted of 40 (61%) patients who were re-established on enteral nutrition. The median (IQR) duration of PN administration was 10 (6-17) days. The most common indication of PN was protracted ileus (n = 25, 63%). Out of 40 of these patients, 35 (88%) patients had good performance status. The median (IQR) survival was 264 (96-564) days. The third group of patients required home PN (n = 7, 11%). Four (58%) patients had short bowel syndrome and three (42%) had terminal intestinal obstruction. All of the patients had good performance status. The median (IQR) duration of PN administration and survival was 241 (90-305) days. Administration of PN appears to be justified in those patients with a good performance status (i.e. patients capable of self-care), which constituted three-quarters of this cohort. In the remaining patients with poor performance status, and particularly those with terminal intestinal obstruction, PN administration was difficult to justify. PN should not be denied based purely on the pathology, although cautious

    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.

    Laparoscopy has become the standard surgery for the treatment of benign ovarian tumors. The aim of this study was to evaluate the appropriateness of laparoscopy for ovarian tumors, including those with malignant potential. A total of 487 patients with adnexal masses underwent laparoscopic surgery in Social Insurance Chukyo Hospital from January 2000 to December 2012. We reviewed 471 cases that fulfilled the criteria set for this study, and examined 10 cases with unexpected ovarian malignancy to analyze their preoperative diagnosis, second surgery, postoperative chemotherapy, and prognosis. The ages of the 471 patients ranged from 13 to 50 years, with a median of 31. Nulliparous patients numbered 321(68.1%). Of all, 436 patients mostly consisted of those with endometrioma, benign ovarian neoplasm or functional cyst. In all, we histologically identified 10 women with malignancy: 6 with borderline ovarian tumors (BOT), 2 with ovarian cancer, and 2 with histologically rare tumors (immature teratoma and granulosa cell tumor). All patients with BOT were diagnosed with a mucinous histology. Two patients underwent both second radical surgery (hysterectomy and contra- or bilateral salpingo-oophorectomy) and chemotherapies that consisted of CBDCA and PTX or DTX. Thus, 2 patients underwent staging procedures, but the remaining 8 cases did not. None of them had evidence of recurrences. With accurate staging and careful postoperative follow-up, laparoscopic surgery could be a feasible initial operation for patients with adnexal masses including early-stage ovarian malignancy.

    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

    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. The DWI demonstrated an excellent diagnostic performance in discriminating between benign and malignant ovarian neoplasms

    Malignant mixed mesodermal tumors (MMMTs) of the ovary are rare, highly aggressive neoplasms that arise most commonly in postmenopausal women. Histologically, they consist of a mixed population of malignant epithelial and mesenchymal elements. Neuroectodermal differentiation in ovarian MMMTs is exceedingly uncommon, with only a few case reports in the literature. We present a case of an ovarian MMMT with neuroectodermal differentiation in a 78-year-old female patient. Histologically, the tumor was composed of epithelial, mesenchymal, and neuroectodermal elements. The neuroectodermal component was predominantly that of a medulloepithelioma, with scattered areas displaying features of an anaplastic astrocytoma, including rare ganglion cell differentiation. The neuroectodermal component showed immunoreactivity for glial fibrillary acidic protein, synaptophysin, and S100 protein. Ultrastructurally, the neuroectodermal component was populated by cells with irregular nuclei, finely dispersed chromatin, rudimentary cell junctions, and a delicate basement membrane, all of which have been described in medulloepitheliomas. DNA ploidy analysis was also performed on the various components of the tumor and compared with 3 additional cases of MMMT without neuroectodermal differentiation and 2 ovarian immature teratomas. Our findings suggest that the neuroectodermal component may arise from a separate clone or at least evolves at an earlier stage of tumor development.

    New treatment strategies for prostate cancer have recently been developed, but multiple malignancies remain a major concern. The aim of this study was to evaluate the characteristics of multiple malignancies and to analyze the risk of secondary malignancies after radiotherapy for prostate cancer. From 2000 to 2011, 150 patients with prostate cancer were treated with curative radiotherapy in our department. Patient age range was 54-92 years (median, 70 years), and the follow-up period was 4-142 months (median, 48 months). The incidence of multiple primary cancers was compared with the estimated incidence. A total of 147 patients (98 %) survived more than 12 months (12-142 months; median, 48 months); 20/150 patients (13 %) died within 10 years. Cause of death was recurrent prostate cancer in 11 patients, other primary malignancies in 7 patients, and cardiovascular disease in 2 patients. Multiple primary cancers were present in 26 of 150 patients (17 %), including 16 subsequent malignancies (11 %) with latent periods of 13-83 months (median, 43 months). The subsequent non-prostate malignancies were lung cancer in 4 patients, urinary bladder or ureter cancer in 4, stomach cancer in 3, malignant lymphoma in 2, and other in 3. Analysis of the observed incidence of secondary malignancies compared with the estimated incidence in the general population revealed a higher incidence of ureter cancer and malignant lymphoma. Close attention should be paid to secondary malignancies after radiotherapy for prostate cancer, including malignancies occurring within 5 years, which could be attributable to radiotherapy.

    To compare subjective ultrasound assessment and the ADNEX model with ultrasound-guided tru-cut biopsy to differentiate disseminated primary ovarian cancer from metastatic non-ovarian cancer. This was a prospective study including 143 consecutive women with disseminated malignancy of unknown primary origin, with a pelvic tumor/carcinosis. Women underwent either transvaginal or transrectal ultrasound as well as transabdominal ultrasound examination followed by tru-cut biopsy. The ultrasound examiner assessed tumor morphology, spread in the pelvis and abdomen, and predicted tumor origin as primary ovarian or metastatic using both subjective assessment and the ADNEX model. Histology from tru-cut biopsy served as the gold standard for assessment of diagnostic accuracy. Biopsy adequacy and the complication rate were assessed. Tru-cut biopsy was performed transvaginally in 131/143 (92%) women. Two women needed inpatient care (one had abdominal wall hematoma, and one infection). Biopsy resulted in a conclusive diagnosis in 126/143 (88%) women, amongst whom cytoreductive surgery was performed in 30/126 confirming the diagnosis in all cases. Non-ovarian metastatic cancer was found in 37/126 (29%) women and primary ovarian cancer in 89/126 (71%) women. Subjective ultrasound evaluation had a sensitivity of 82% (73/89) and a specificity of 70% (26/37) in predicting primary ovarian cancer. The ADNEX model had an area under the receiver-operating characteristics curve of 0.891 (95% CI, 0.794-0.946) (in women with an ovarian lesion, n = 104). Tumor origin was associated with age, CA 125, previous neoplasia, presence of omental cake and tumor mobility. Subjective ultrasound assessment and the ADNEX model can both be used to predict whether a pelvic tumor is metastatic and of non-ovarian origin, indicating the need for tru-cut biopsy, which is associated with very few complications and will provide a conclusive diagnosis in nine out of 10 women.

    The aim of this study was to describe the clinical and oncological outcomes of women with malignant bowel obstruction (MBO) for relapsed ovarian cancer and peritoneal carcinomatosis. A retrospective cohort study was performed in all consecutive patients admitted at Instituto Valenciano de Oncología, Valencia, Spain, between July 2013 and July 2016 with MBO for relapsed ovarian cancer and peritoneal carcinomatosis. All patients underwent the same protocol of conservative management. Surgical treatment was indicated only in selected cases. There were a total of 22 patients presenting 59 episodes of MBO; 17 (77.2%) of those patients presented more than 1 episode of MBO. All patients had serous epithelial ovarian cancer; 18 (81.8%) were high grade, and 4 (18.2%) low-grade tumors. The median (range) number of episodes per patient was 3 (range, 1-7) with a mean length of hospitalization of 13 (SD, 13.6) days. The median time interval between episodes of MBO (54 episodes in 17 patients) was 17 days (range, 1-727 days). Twenty of 22 patients died with a median overall survival time from the first episode of MBO of 95 days (95% confidence interval, 49-124 days). Patients with MBO due to relapsed epithelial ovarian cancer in the peritoneal carcinomatosis setting have a short life expectancy, presenting a median of 3 episodes of MBO until death, with a short time interval between episodes. These findings show that bowel obstruction can represent a constant status over time until death.

    Abnormalities in tumor suppressors p14, p16 and p53 are reported in several human cancers. In ovarian epithelial carcinogenesis, p16 and p53 show higher immunohistochemical staining frequencies in malignant tumors and are associated with poor prognoses. p14 was only analyzed in carcinomas, with conflicting results. There are no reports on its expression in benign and borderline tumors. This study aims to determine p14, p16 and p53 expression frequencies in ovarian benign, borderline and malignant tumors and their associations with clinical parameters. A cross-sectional study utilizing immunohistochemistry was performed on paraffin-embedded ovarian epithelial tumor samples. Clinical data were collected from medical records. Fisher's exact test and the Bonferroni correction were performed for frequency associations. Survival comparisons utilized Kaplan-Meier and log rank testing. Associations were considered significant when p < 0.05. p14 absent expression was associated with malignant tumors (60 % positive) (p = 0.000), while 93 % and 94 % of benign and borderline tumors, respectively, were positive. p16 was positive in 94.6 % of carcinomas, 75 % of borderline and 45.7 % of benign tumors (p = 0.000). p53 negative staining was associated with benign tumors (2.9 % positive) (p = 0.016) but no difference was observed between borderline (16.7 %) and malignant tumors (29.7 %) (p = 0.560). No associations were found between expression rates, disease-free survival times or clinical variables. Carcinoma subtypes showed no difference in expression. This is the first description of p14 expression in benign and borderline tumors. It remains stable in benign and borderline tumors, while carcinomas show a significant absence of staining. This may indicate that p14 abnormalities occur later in carcinogenesis. p16 and p53 frequencies increase from benign to borderline and malignant tumors, similarly to previous reports, possibly reflecting the

    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.

    Autoimmune pathogenesis is responsible for a subset of primary ovarian insufficiency (POI) cases. The significance of autoantibodies for POI, however, remains unclear. A total of 250 women with idiopathic POI and 256 age-matched healthy women were enrolled. The presence in serum of adrenal cortex autoantibody (AAA), detected by indirect immunofluorescence and non-organ-specific antibodies, including antinuclear antibody, anti-cardiolipin antibody, and anti-double stranded DNA antibody, detected by enzyme-linked immunosorbent assay, was compared. Ovarian biopsy was carried out for histology assessment. Adrenal function was followed-up in 15 women with POI who were positive for AAA. Higher frequency of positive AAA was observed in women with POI (19.2%) compared with controls (5.9%, P < 0.01). No difference in anti-cardiolipin antibody, antinuclear antibody and anti-double stranded DNA antibody was found between the two groups. Ovarian biopsies in 13 women with POI (six AAA positive and seven negative) showed atrophic ovaries devoid of follicles. One out of fifteen women positive for AAA had symptoms of adrenal insufficiency 3 years after POI diagnosis. Significantly higher positive frequency of AAA in POI patients suggests the role of autoimmune disturbance in pathogenesis. Therefore, AAA may serve as a biomarker for ovarian autoimmunity.

    Is ovarian tissue cryopreservation using vitrification followed by in vitro activation (IVA) of dormant follicles a potential approach for infertility treatment of patients with primary ovarian insufficiency (POI)? Our vitrification approach followed by IVA treatment is a potential infertility therapy for POI patients whose ovaries contain residual follicles. Akt (protein kinase B) stimulators [PTEN (phosphatase with TENsin homology deleted in chromosome 10) inhibitor and phosphatidyinositol-3-kinase (PI3 kinase) stimulator] activate dormant primordial follicles in vitro and ovarian fragmentation disrupts the Hippo signaling pathway, leading to the promotion of follicle growth. We treated POI patients with a combination of ovarian vitrification, fragmentation and drug treatment, followed by auto-transplantation, and reported successful follicle growth and pregnancies. Prospective clinical study of 37 infertile women with POI between 12 August 2011 and 1 November 2013. We enrolled 10 new patients since the previous publication. POI patients were originally selected based on a history of amenorrhea for more than 1 year and elevated serum FSH levels of >40 mIU/ml (n = 31) but this was later changed to >4 months, age <40 years and serum FSH levels of >35 mIU/ml (n = 6) (mean 71.8 ± 30.8, range 35.5-197.6) so as to include patients with a shorter duration of amenorrhea. Under laparoscopic surgery, ovariectomy was performed and ovarian cortices were dissected into strips for vitrification. Some pieces were examined histologically. After warming, two to three strips were fragmented into smaller cubes before culturing with Akt stimulators for 2 days. After washing, ovarian cubes were transplanted beneath the serosa of Fallopian tubes under laparoscopic surgery. Follicle growth was monitored by ultrasound and serum estrogen levels. After oocyte retrieval from mature follicles, IVF was performed. Among 37 patients, 54% had residual follicles based on histology. Among

    Objective: To evaluate the performance of mesothelin, CA125, HE4 and ROMA index in the detection of malignant ovarian tumors. 
Study Design: This is a cross-sectional study including 199 women with adnexal masses (67 with malignant tumors and 132 with benign tumors) and 150 healthy women (controls). We used a recursive multivariate partitioning algorithm to assess the contribution of each of the serum markers and the ROMA index to the discrimination of women with malignant tumors. Also, the areas under the ROC curves (AUC) for each of the serum markers and for the ROMA index were compared using the Venkatraman's projection-permutation test. 
Results: In the recursive model, CA125 had the best performance in discriminating women with malignant tumors. In women with normal-range CA125 levels, none of the other markers contributed to the discrimination of women with malignant tumors. In women with elevated CA125 levels, elevated HE4 levels were associated with an increased risk of harboring a malignant tumor. The AUC for mesothelin was smaller than that for all the other curves, and both the ROMA index and CA125 had better AUC than HE4. 
 Conclusion: In women with normal CA125 levels, neither mesothelin nor HE4 contributed to discriminate women with malignant ovarian tumors; however, for women with elevated CA125 levels HE4 may help discriminating those who have a malignant ovarian tumor.

    2014-02-01

    Amyloid accumulation in the thyroid gland leading to a clinically detectable mass, known as amyloid goiter, is a rare condition associated with primary amyloidosis. Moreover, a localized primary amyloid goiter involving only the thyroid gland is rarer still. Here, we report a patient with a localized primary amyloid goiter that had grown rapidly, causing dysphagia and dyspnea on exercise, and confused us with malignancy such as anaplastic carcinoma. After surgery, no further symptoms occurred. A diagnosis of amyloid goiter was established on microscopic examination. In patients with a rapidly enlarging thyroid gland presenting with dysphagia, dyspnea, or hoarseness, amyloid goiter and malignancy should both be suspected, even when systemic amyloidosis is not suspected.

    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.

    Malignant ovarian germ cell tumors are rare entities, although they account for a large proportion of ovarian masses in young women. These tumors have traditionally been removed via laparotomy, because of their large size and solid nature. The use of laparoscopy for treatment of adnexal masses in adolescents has been heavily debated and poorly studied to date. A 16-year-old female patient presented with abdominal pain and an 11-cm adnexal mass on ultrasound. An emergent laparoscopic salpingo-oophorectomy was performed without complication. Pathology revealed a mixed malignant ovarian germ cell tumor. Laparoscopic fertility-sparing surgery offers many benefits over laparotomy, and should be considered in cases of young women with large adnexal masses, even if potential for malignancy exists.

    Primary malignant melanoma of urethra is an extremely rare entity. It has very poor prognosis. A 62-year-old post-menopausal female presented with complaints of voiding difficulty and a mass projecting from external urethral meatus. External genital examination revealed a growth arising from urethral meatus with blood-stained discharge from its surface. Biopsy from lesion confirmed the diagnosis to be malignant melanoma. Metastatic work up for the malignancy was negative. We describe the surgical management of this pathology at our tertiary care center and discuss the various treatment options possible in this scenario.

    To investigate the incidence of malignant transformation and P53 and P16 expression in teratomatous skin of ovarian mature cystic teratoma. Data on ovarian teratoma specimens in nearly 10 years were reviewed. P53 and P16 expression were detected by immunohistochemistry in 25 cases of teratomatous skin of ovarian mature cystic teratoma, 20 cases of squamous cell carcinoma and 2 cases of squamous cell carcinoma originated from teratomatous skin. Of 1913 cases of ovarian mature cystic teratoma in nearly 10 years, only two cases of squamous cell carcinoma were found in teratomatous skin, with malignant transformation rate of 0.1045%. P53 expression was detected in 2 cases squamous cell carcinoma originated from teratomatous skin and P16 overexpression in one. There were no expressions of P53 and P16 in 25 cases of teratomatous skin of ovarian mature cystic teratoma. Of 20 cases of squamous cell carcinoma P53 overexpression (positive rate of 55%) was detected in 11 cases, P16 overexpression (positive rate of 35%) in 7 cases. The positive rates of P53 and P16 expression in squamous cell carcinomas were significantly higher than that in the teratomatous skins (p< 0.001, p= 0.002). There was low risk of malignant transformation in teratomatous skin of ovarian mature cystic teratoma which can be explained by lower P53 and P16 expressionin teratomas than that in squamous cell carcinoma.

    To present the ultrasound and magnetic resonance imaging findings that may allow for a prospective diagnosis and expectant management of decidualized endometriomas because the rare occurrence of decidualization in the ectopic endometrial stroma of an endometrioma during pregnancy can mimic ovarian cancer at imaging. Smooth lobulated mural nodules with prominent internal vascularity were noted in an apparent right ovarian endometrioma on serial ultrasound studies in a 34-year-old woman at 12, 21, 27, and 30 weeks of gestation. Magnetic resonance imaging demonstrated the nodules to be strikingly similar in intensity and texture to the decidualized endometrium in the uterus on T2-weighted sequences. A provisional diagnosis of decidualized endometrioma allowed for expectant management with immediate postpartum resection and confirmation of the diagnosis. Decidualized endometrioma can mimic ovarian malignancy during pregnancy, but a prospective diagnosis may be possible when solid smoothly lobulated nodules with prominent internal vascularity within an endometrioma are seen from early in pregnancy, and the nodules demonstrate marked similarity in signal intensity and texture with the decidualized endometrium in the uterus at magnetic resonance imaging.

  12. Malignant ascites in ovarian cancer and the role of targeted therapeutics.

    2014-04-01

    Ovarian cancer (OC) is the eighth most lethal gynecological malignancy and the main cause of gynecological cancer death in industrialized countries. Malignant ascites is often found in OC, with about 10% of patients suffering from recurrent OC. Tumor cells in OC-associated malignant ascites promote disease recurrence and patient mortality is mainly associated with widespread metastasis to serosal surfaces and accompanying peritoneal effusions. Targeted therapies have recently been developed as novel therapeutic options for malignant ascites. The tri-functional anti-epithelial cell adhesion molecule and anti-cluster of differentiation 3 monoclonal antibody catumaxumab has been assessed in the therapy of malignant ascites, and proven to significantly reduce the ascitic flow rate when applied into the peritoneal cavity. The anti-angiogenic targeted agent bevacizumab has also shown good effects in the symptomatic treatment of malignant ascites, significantly prolonging the time until the next paracentesis. Vascular endothelial growth factor (VEGF) Trap, or aflibercept, is a fusion protein that inhibits VEGF-receptor binding. Aflibercept has proven to be effective in reduction of ascites, diminishing clinical symptoms of ascites and prolonging the time to next paracentesis. All three agents we review in the present article are effective in symptomatic control of ascites, leading to a rapid reduction of effusion and prolonging the time interval between paracenteses. However, no improvement in overall survival was observed in any of the clinical trials reported. We, thus, conclude that further investigations on larger patient series are needed to clarify whether the reduction of ascites by these targeted agents leads to a prolongation in tumor-related survival or not.

    FSH inactivity due to secondary hypoglycosylation has been suggested as a potential mechanism for primary ovarian insufficiency in classic galactosemia. To investigate the role of FSH and to gain insight in the timing of the damage, ovarian stimulation tests were performed and data on ovarian imaging collected. Fifteen patients with primary ovarian insufficiency underwent ovarian stimulation with gonadotropins. Only one patient showed a normal increase in estradiol level, all the others had a low or no estradiol response. Anti-Müllerian hormone measurement in all girls and women showed levels below the detection limit of 0.10 μg/l. Ovarian volumes were evaluated by MRI in 14 patients and compared to age matched controls, prepubertal controls and postmenopausal controls. The ovarian volumes of the galactosemic girls were smaller than those of the age matched controls (p = 0.001) and the prepubertal ovaries (p = 0.008), and did not differ significantly from postmenopausal ovarian volumes (p = 0.161). In conclusion we found no evidence that FSH inactivity plays a role in primary ovarian insufficiency in classic galactosemia. Moreover, ovarian imaging results point to an early onset of ovarian failure in this disease.

    Mucinous carcinoid tumor of the ovary is an uncommon lesion in reproductive-age women. If a patient status post total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) for this tumor presents with a pelvic mass, recurrence of the tumor must be considered, as must the presence of residual ovarian tissue producing physiologic cysts with mass effect, termed the "ovarian remnant syndrome." Benign ovarian follicle cysts may have cellular atypia and mimic malignancy. A female, one year status post TAH-BSO for mucinous carcinoid tumor of the ovary, presented with pelvic mass. Clinical and radiologic evidence supported the diagnosis of recurrent tumor. Aspiration biopsy material was compatible with malignancy, and immunocytochemical stains supported a neuroendocrine origin of the cells. Surgical excision and histologic examination of the mass revealed ovarian tissue with features of corpus luteum and follicular cyst. Numerous pitfalls exist when considering an unusual tumor. While the patient's history, clinical impressions and immunocytochemistry may strongly suggest malignancy, more common benign entities may mimic malignancy and should be considered in the differential diagnosis.

    Primary carcinoid tumors of the ovary are rare accounting for only 1% of neoplasms that are associated with the carcinoid syndrome. However, the carcinoid syndrome can occur in the absence of hepatic metastases due to the release of vasoactive peptides directly into the systemic circulation via the ovarian vein. We present a 69-yr-old woman presenting with carcinoid valvular disease and congestive cardiac failure who was found to have a primary left ovarian carcinoid tumor. At operation it was noted that the left ovarian vein had an unusually firm and thickened appearance, and histologic examination revealed marked fibromuscular medial hypertrophy with luminal compression. There was no associated vascular elastosis. This ovarian venous alteration appears to represent a novel addition to the spectrum of cardiovascular injuries associated with carcinoid tumors.

    Ovarian cancer is the leading cause of mortality related to gynecologic malignancies in Sweden but there is no current screening program. Based upon epidemiological research there is evidence that certain reproductive factors are associated with ovarian cancer risk. Most studies generally indicate that each childbirth incurs a 15-20% risk reduction. Women who have used oral contraceptives for 5 years or longer experience about half the risk of ovarian cancer compared with never users. Breastfeeding seems to be protective while age at menarche and at menopause are less consistent risk predictors. Tubal ligation and hysterectomy seem to reduce ovarian cancer risk by up to 80%. Although some studies found endometriosis, polycystic ovarian syndrome (PCOS) and pelvic inflammatory disease (PID) to be positively related to ovarian cancer, the role of these factors is not yet established. Most recent studies observed an approximately 50% ovarian cancer risk increase among ever users of hormone replacement therapy (HRT) compared with never users, and the risk increased further with long-term use. There is less information concerning separate estrogen and progestin effects of HRT and ovarian cancer risk. Although the cause of ovarian cancer remains obscure, hypotheses relating to "incessant" ovulation, excessive gonadotropin secretion, retrograde carcinogen transportation, apoptosis and estrogen/progestin imbalance have been invoked as etiological explanations. All these hypotheses find various epidemiological support. The aim of this review is to summarize the epidemiological findings on reproductive factors and ovarian cancer risk. These findings are considered in the context of etiologic hypotheses and some new research areas are suggested.

    Based in epidemiological evidence, repetitive ovulation has been proposed to play a role in the origin of ovarian cancer by inducing an aberrant wound rupture-repair process of the ovarian surface epithelium (OSE). Accordingly, long term cultures of isolated OSE cells undergo in vitro spontaneous transformation thus developing tumorigenic capacity upon extensive subcultivation. In this work, C57BL/6 mouse OSE (MOSE) cells were cultured up to passage 28 and their RNA and DNA copy number profiles obtained at passages 2, 5, 7, 10, 14, 18, 23, 25 and 28 by means of DNA microarrays. Gene ontology, pathway and network analyses were focused in passages earlier than 20, which is a hallmark of malignancy in this model. At passage 14, 101 genes were up-regulated in absence of significant DNA copy number changes. Among these, the top-3 enriched functions (>30 fold, adj p < 0.05) comprised 7 genes coding for centralspindlin, chromosome passenger and minichromosome maintenance protein complexes. The genes Ccnb1 (Cyclin B1), Birc5 (Survivin), Nusap1 and Kif23 were the most recurrent in over a dozen GO terms related to the mitotic process. On the other hand, Pten plus the large non-coding RNAs Malat1 and Neat1 were among the 80 down-regulated genes with mRNA processing, nuclear bodies, ER-stress response and tumor suppression as relevant terms. Interestingly, the earliest discrete segmental aneuploidies arose by passage 18 in chromosomes 7, 10, 11, 13, 15, 17 and 19. By passage 23, when MOSE cells express the malignant phenotype, the dysregulated gene expression repertoire expanded, DNA imbalances enlarged in size and covered additional loci. Prior to early aneuploidies, overexpression of genes coding for the mitotic apparatus in passage-14 pre-malignant MOSE cells indicate an increased proliferation rate suggestive of replicative stress. Concomitant down-regulation of nuclear bodies and RNA processing related genes suggests altered control of nuclear RNA maturation

    Intraoperative electron beam radiation therapy (IOEBRT) in the treatment of ovarian malignancies was investigated at the Clement O. Miniger Radiation Oncology Center (COMROC). Nine patients were operated in the COMROC IOEBRT operating amphitheater and five were found to have disease sufficiently limited to allow for IOEBRT. The patients' ages ranged from 13 to 80 (median 53) years. Five patients had serous cystadenocarcinoma, one papillary adenocarcinoma, one mixed germ cell tumor, one squamous cell carcinoma, and one granular cell tumor of the ovary. The median survival of the non-IOEBRT group was 13 (range 12-29) months, while the IOEBRT group's median survival was 14 (range 18-46) months. All of the patients tolerated IOEBRT well without addition to the surgical morbidity.

    A 49-year-old woman with ovarian teratoma received 131I treatment three times for an unresectable mass containing malignant thyroid tissue after surgery. Repeated 131I treatment effectively reduced serum thyroglobulin (Tg) level and tumour uptake of 131I, despite absence of any change in size of the treated tumour. Treatment did not inhibit the increase of serum CA-125 and tumour 201Tl uptake, associated with progression of a radioresistant intratumoral hyper-perfused tissue component, detected by colour Doppler ultrasound. Serum CA-125 level and tumour 201Tl uptake were not significantly changed despite temporary increases in serum Tg level after each 131I treatment. These observations indicate the importance of diagnostic measures using combined functional imaging and tumour markers in managing this rare tumour.

    Malignant fibrous histiocytoma (MFH) is an aggressive soft tissue sarcoma known to occur in various organs. Primary MFH arising in the lung is quite rare. Herein we report a case of a 61-year-old male with primary pulmonary MFH and explore the underlying molecular mechanisms by next-generation sequencing (NGS). Five gene mutations in TSC2, ARID1B, CDK8, KDM5C and CASP8 were detected, and the mTOR inhibitor might be an effective treatment for this patient. In addition, we reviewed the scientific literature of approximately 23 primary pulmonary MFH case reports since 1990 and summarized the clinical features and prognosis of this rare pulmonary malignant tumor.

    We investigate linear and nonlinear optical properties of standard human ovarian cancer cells (cell line: A2780cp) in vitro. Cells were treated by graphene quantum dots (GQDs) with two special concentrations. Nontoxicity of GQDs was examined in standard biological viability tests. Cancerous cells were fixed on a glass slide; then, interaction of light with biofilms was studied in linear and nonlinear regimes. Absorption spectra of untreated biofilms and biofilms with two different concentrations of GQDs was studied by UV-visible spectrophotometer. Optical behavior of biofilms in a linear regime of intensity (with low-intensity laser exposure) was reported using a simple optical setup. After that, we compared the attenuation of light in biofilm of cancerous cells with and without GQDs. Nonlinear behavior of these biofilms was investigated by a Z-scan setup using a continued wave He-Ne laser. Results showed that GQDs decreased the extinction coefficient and changed the sign and exact value of the nonlinear refractive index of malignant ovarian cells noticeably. The nonlinear refractive index of studied cells with no GQDs treatment was in the order of 10-8 (cm2/w) with a positive sign. This quantity changed to the same order of magnitude with a negative sign after GQDs treatment. Thus, GQDs can be used for cancer diagnosis under laser irradiation.

    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.

    We report a rare case of primary amelanotic malignant melanoma of the female urethra. A 58-year-old female with complaint of nodule on the external urethral meatus was referred to our hospital. Pathological diagnosis of the biopsy specimen from the nodule was malignant melanoma. Computed tomography of the chest and abdomen as well as bone scan showed no evidence of metastasis. Sentinel biopsy from the inguinal lymph nodes revealed no metastasis. Thereafter, the patient underwent radical urethrectomy, whose limits of resection were the bulbocavernosal muscles bilaterally, the arch of the pubic symphysis anteriorly, the anterior vaginal wall posteriorly, and the urethra up to the level of the bladder neck superiorly. The histopathological diagnosis was amelanotic malignant melanoma of the urethra. The patient had received six cycles of DAV-Feron (dacarbazine, nimustine, vincristine, and interferon-beta) in an adjuvant setting, and there is no sign of recurrence 25 months after operation.

    1987-01-01

    The relationship between chronic lymphocytic leukaemia (CLL) and primary malignant neoplasms was evaluated using data from the Hematology Division in Beilinson Medical Center and the Israel Cancer Registry. The study population consisted of 81 patients diagnosed between 1962 and 1984. A total of 16 patients were found to have 21 malignant neoplasms in addition to their CLL. Excluding patients with nonmelanoma skin tumours, a 1.7 increased risk (statistically not significant) for developing second malignant neoplasms in CLL patients was detected. The only tumour which occurred significantly more than expected subsequent to CLL diagnosis was brain cancer. The coexistence of multiple cancers in the same patient was diagnosed in four of the patients. The results of this study further support the hypothesis that patients with CLL are prone to develop second neoplasms. PMID:3684832

    As a primary imaging modality, ultrasonography (US) can provide diagnostic information for evaluating ovarian masses. Using a pattern recognition approach through gray-scale transvaginal US, ovarian masses can be diagnosed with high specificity and sensitivity. Doppler US may allow ovarian masses to be diagnosed as benign or malignant with even greater confidence. In order to differentiate benign and malignant ovarian masses, it is necessary to categorize ovarian masses into unilocular cyst, unilocular solid cyst, multilocular cyst, multilocular solid cyst, and solid tumor, and then to detect typical US features that demonstrate malignancy based on pattern recognition approach.

    This study aimed to investigate the correlation between multiple early gastric cancer (MEGC) and multiple primary malignancies during the follow-up of patients with gastrectomy. The number of primary tumors detected in other organs after gastrectomy for early gastric cancer (EGC) has been increasing because of improved survival and surveillance programs. A total of 3,129 patients underwent radical gastrectomy for treatment of EGC at Samsung Medical Center from January 2000 to December 2005. Of these, 3,057 patients were selected and their medical records were retrospectively analyzed. Among the 3,057 patients, 148 (4.8%) had MEGC, 84.5% were male, 57.4% were over 60 years old, 42.6% had a macroscopic type EGC IIb main lesion, and 68.9% had well-differentiated tumors with a significantly high incidence of MEGC. There were no differences between patients with solitary early gastric cancer (SEGC) and those with MEGC with regard to overall survival or recurrence-free survival, but MEGC was an independent risk factor for metachronous primary malignancies in other organs (P=0.004, hazard ratio [HR]=2.444). MEGC is not a risk factor for poor prognosis after curative gastrectomy, but it is a risk factor for metachronous primary malignancies in other organs during postoperative follow-up; therefore, careful surveillance is needed.

    Multiple primary malignancy is defined as two or more malignancies detected in an individual person. In particular, synchronous quintuple primary malignancy is extremely rare. A 52-year-old male with anal pain and intermittent blood-tinged stool was diagnosed with malignancies in the stomach, jejunum, ascending colon, transverse colon and rectum. He underwent a subtotal gastrectomy, segmental resection of the jejunum and total protocolectomy with end ileostomy. The postoperative pathologic findings were moderate differentiated gastric adenocarcinoma (pT1bN0M0, pStageIA), combined adenocarcinoma and neuroendocrine carcinoma of the jejunum (pT3N0M0, pStageIIA), three mucinous adenocarcinoma of the ascending colon (pT3N0M0, pStageIIA), transverse colon (pT1N0M0, pStageI) and rectum (pT3N1aM0, pStageIIIB). The tumors did not lack MLH-1 and MSH-2 expression, as the markers (bat26, D5S346, bat25, D2S123) suggest MSI-H presence. Adjuvant chemoradiotherapy was started according to regimen, FOLFOX 4 for advanced rectal cancer. Six years post-operation, the patient is currently attending regular follow-ups without recurrence or metastasis. PMID:28104993

    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. 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. 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. HE4 and ROMA showed a very high specificity, but were less sensitive than CA-125 and

    Breast sarcoidosis is rare and usually presents in patients with known sarcoid involving other organ systems. In the breast, sarcoidosis may mimic malignancy which must be excluded by core biopsy. We report a very unusual case of primary breast sarcoidosis with incidentally discovered breast carcinoma. The roles of mammography, ultrasound, and MRI in the diagnosis as well as other potential differential diagnosis are discussed. PMID:22919560

    Malignant pleural effusion (MPE) is a frequent complication in many types of tumors diminishing the patient's ability to perform activities. Despite various studies on talc treatment, some doubts about its safety and effectiveness remain, so the search for a more ideal intrapleural agent continues. We analyzed the effectiveness and safety of intrapleural paclitaxel in ovarian and breast cancer patients. The primary endpoint was overall response rate (ORR); secondary objectives included time to progression (TTP), overall survival (OS) and safety of intrapleural paclitaxel. Pharmacokinetics of the drug was also analyzed. After drainage of pleural effusion and lung re-expansion, paclitaxel 120 mg/m(2) diluted in normal saline was infused through a preinserted catheter which was immediately closed and reopened 24 h later. Blood and pleural fluid samples were collected 1, 4 and 24 h after the end of paclitaxel instillation. When MPE was less than 200 ml/24 h the catheter was removed. Chest radiographs were performed at the beginning of intrapleural paclitaxel, at 1 and 2 months later or with clinical deterioration. We enrolled 18 patients with recurrent MPE: 11 with ovarian cancer and 7 with breast cancer. ORR was 77.8% at 1 month and 88.8%. at 2 months. Median TTP was 5.5 months (CI 95% 0.9-10.1) and median OS was 8.9 months (CI 95% 0.1-17.6). Patients achieving a complete response obtained a statistically significant longer survival than did patients with partial response or progressive disease. Chest pain, fever, and dyspnea were the most frequent side effects. Intrapleural paclitaxel concentrations were very high (mean ± SD = 478 ± 187 mg/l) and declined slowly (mean 24 h reduction ~30%). Detectable but low taxol plasma levels were found in most patients (mean ± SD = 0.045 ± 0.073 mg/l). Intrapleural paclitaxel is a safe and effective palliative treatment for MPE from breast and ovarian cancers and may be integrated with systemic chemotherapy.

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

    Transcoelomic route is the most common and the earliest route of metastasis, causing the ascites formation in advanced epithelial ovarian cancer (EOC). We demonstrated that interleukin 6 (IL-6) is enriched in the malignant ascites from patients with ovarian cancer, which enhanced invasive properties of EOC cells. Interestingly, the expression of IL-6R on cell membrane of EOC cells correlated with ascites-induced invasion. Selective knockdown of IL-6R or inhibition with IL-6 neutralizing antibody, suppressed the stimulatory effects of ascites on EOC invasion. Moreover, the ascites treatment induced the phosphorylation of JAK2-STAT3 and use of selective inhibitors of JAK2 and STAT3, blocked the expression of epithelial-mesenchymal transition related proteins in parallel with the suppression of EOC invasion. Thus, IL-6/IL-6R mediated JAK2-STAT3 signaling pathway could be a promising therapeutic target for anticancer therapy in ovarian cancer patients with ascites. PMID:27825119

    Malignant priapism is a definition invented in 1938 by Peacock, defined as a persistent erection, not related with sexual activity, caused by cavernous sinus and associated venous systems invasion with malignant cells. Penile secondary lesions are rare entities. Primary locations are usually the pelvic cavity organs, namely the prostate and the bladder as the most common ones. Priapism as a first manifestation of these kinds of lesions is even rarer. The aim was to present a 52-year-old patient harboring a penile metastasis that originated in the primary prostate adenocarcinoma, manifesting itself as a “common” priapism. The patient referred to the emergency room presenting with a priapism and nodules at the coronal sulcus, without previous similar episodes. His evolution until properly diagnosed was catastrophic with multiple lymph nodes, bone and organ involvement, and with his demise soon after from serious bleeding and congestive heart failure, almost 2 months after he first came to the emergency room. We review the literature concerning malignant priapism, diagnosis, and current treatment and survival perspectives. PMID:26229335

    As the survival rate of cancer patients has increased over the last few decades, the risk of cancer survivors developing second primary malignancies has gained attention. We report two rare cases of second primary hematologic malignancy detected by (18)F-fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) during follow-up for primary solid malignancies. Acute lymphoblastic leukemia developed in a breast cancer patient and non-Hodgkin lymphoma in an anal cancer patient. F-18 FDG PET/CT findings led to the diagnosis of unexpected second primary hematologic malignancy in cancer survivors in these two cases.

    Anorectal malignant melanoma (AMM) is most common primary melanoma of gastrointestinal tract, accounting for 0.05% and 1% of all colorectal and anal cancers. We reported an 85 year-old woman with no significant past medical history who presented two-month period of rectal bleeding, abdominal pain, tenesmus and 2kg weight-loss. Laboratory markers were unremarkable, although rectal examination revealed two small haemorrhoids and a firm, non-obstructing mass in the lower rectum. Colonoscopy confirmed presence of an ulcerated pigmented neoplasm arising at dental line [A,B]. No distant metastases were found on computed tomography [C] although presented metastatic regional lymph nodes on pelvic MRI [D]. Therefore, abdominoperineal resection was performed, confirming loco-regional disease. Histopathology showed malignant melanoma with positive stains in immunohistochemistry for protein S100, HMB-45 and Melan-A [E,F,G,H] and stained negative for c-Kit.

    Urine cystein proteinase (UCP) and serum CA125 were measured in 40 patients with malignant ovarian tumor (malignant group), 40 patients with benign ovarian tumor (benign group), and 40 normal control (normal group). 28 patients in the malignant group underwent UCP and CA125 measurement pre-operation, post-operation, and during three courses of chemotherapy. The enzyme activity of UCP in the malignant group was significantly higher than that in the benign and normal groups (P < 0.05 or 0.01). The values of UCP in patients with malignant tumor of stages II-IV were significantly higher compared with those of stages I-II (P < 0.01, 0.05). The activity of UCP was elevated pre-operation, post-operation, and was much higher on the seventh day postoperation. After the seventh day, UCP activity decreased gradually. Serum CA125 was also detected pre-operation, at 7.30 and 60 days post-operation. The levels of UCP and CA125 pre-operation and 30, 60 days post-operation in the patients whose residual carcinoma lesions were > 2 cm in diameter were apparantly higher than those with no residual lesions (P < 0.05). UCP and CA125 values were measured in six patients before relaparotomy. The sensitivity, specificity, accuaracy, positive predictive value and negative predictive value for UCP assay are 980%, 100%, 83%, 100% and 50% and those for CA125 assay are 40%, 100%, 80%, 100%, and 25%, respectively.

    To obtain prospective outcomes data on patients (pts) undergoing palliative operative or endoscopic procedures for malignant bowel obstruction due to recurrent ovarian cancer. An institutional study was conducted from July 2002 to July 2003 to prospectively identify pts who underwent an operative or endoscopic procedure to palliate the symptoms of advanced cancer. This report focuses on pts with malignant bowel obstruction due to recurrent ovarian cancer. Procedures performed with an upper or lower gastrointestinal (GI) endoscope were considered "endoscopic." All other cases were classified as "operative." Following the procedure, the presence or absence of symptoms was determined and followed over time. All pts were followed until death. Palliative interventions were performed on 74 gynecologic oncology pts during the study period, of which 26 (35%) were for malignant GI obstruction due to recurrent ovarian cancer. The site of obstruction was small bowel in 14 (54%) cases and large bowel in 12 (46%) cases. Palliative procedures were operative in 14 (54%) pts and endoscopic in the other 12 (46%). Overall, symptomatic improvement or resolution within 30 days was achieved in 23 (88%) of 26 patients, with 1 (4%) postprocedure mortality. At 60 days, 10 (71%) of 14 pts who underwent operative procedures and 6 (50%) of 12 pts who had endoscopic procedures had symptom control. Median survival from the time of the palliative procedure was 191 days (range, 33-902) for those undergoing an operative procedure and 78 days (range, 18-284) for those undergoing an endoscopic procedure. Patients with malignant bowel obstructions due to recurrent ovarian cancer have a high likelihood of experiencing relief of symptoms with palliative procedures. Although recurrence of symptoms is common, durable palliation and extended survival are possible, especially in those patients selected for operative intervention.

    Borderline ovarian tumors (BOTs) represent a heterogeneous group of ovarian epithelial neoplasms. Despite a favorable prognosis, 10-20% of BOTs exhibit progressively worsening clinic. Primary involvement of pelvic organs with echinococcus is very rare. Lymphoepithelioma-like gastric carcinoma is a rare neoplasm of the stomach. A 58-year-old woman referred with abdominal swelling and gastric complaints. Imaging studies revealed a huge cystic mass with multiple septations and solid component, another cystic mass with an appearance of cyst hydatid in the pelvis, and thickening of the small curvature of stomach. Gastroscopy revealed an ulcer with a suspicious malignant appearance, and histology of the endoscopic specimen showed severe chronic inflammation and lymphocytic infiltration. No other involvement of hydatid cyst was detected. In the exploration, there was a 25cm cystic lesion with solid components arising from right ovary, another 6cm cyst over the former, 7cm cystic lesion arising from left ovary, and 10cm mass near the small curvature of the stomach. Excision of the masses; total gastrectomy with esophagojejunal anastomosis; total abdominal hysterectomy; bilateral salpingo-oophorectomy; omentectomy; appendectomy; splenectomy; and pelvic, paraaortic, and coeliac lympadenectomy were performed. Final pathology revealed lymphoepithelioma-like gastric carcinoma, bilateral serous BOT, and hydatid cyst. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world. Preoperative diagnosis of primary pelvic hydatid disease is difficult and awareness of its possibility is very important especially in patients residing in or coming from endemic areas.

    Malignant bowel obstruction (MBO) frequently defines the trajectory of end-stage ovarian cancer and results in severe physical and psychological distress in patients and their caregivers. Venting gastrostomy (VG) is an alternative to both prolonged medical therapy with nasogastric intubation and intestinal bypass/diversion for refractory MBO. Limited published data from large academic research centers support use of VG in patients with advanced ovarian cancer and MBO. In this case series, we describe supportive care outcomes in ovarian cancer patients with MBO receiving the effects of VG in a community setting. Six cases of advanced ovarian cancer involving MBO were evaluated for VG from July 2009 through February 2012. Five of six patients were managed with VG. Our experience suggests that VG may be beneficial in controlling nausea and vomiting in ovarian cancer patients with MBO and that VG placement with concurrent evacuation of large-volume ascites was associated with minimal complications. Future prospective studies to evaluate the benefits of VG are warranted.

    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.

    In this proof-of-principle study, we sought to define whether targeted capture massively parallel sequencing can be employed to determine the origin of metastatic deposits in cases of synchronous primary malignancies and metastases in distinct anatomical sites. DNA samples extracted from synchronous tumor masses in the breast, adnexal, and pelvic-peritoneal regions from a 62-year-old BRCA1 germline mutation carrier were subjected to targeted massively parallel sequencing using a platform comprising 300 cancer genes known to harbor actionable mutations. In addition to BRCA1 germline mutations, all lesions harbored somatic loss of the BRCA1 wild-type allele and TP53 somatic mutations. The primary breast cancer displayed a TP53 frameshift (p.Q317fs) mutation, whereas and the adnexal lesion harbored a TP53 nonsense (p.R213*) mutation, consistent with a diagnosis of two independent primary tumors (i.e. breast and ovarian cancer). The adnexal tumor and all pelvic-peritoneal implants harbored identical TP53 (p.R213*) and NCOA2 (p.G952R) somatic mutations. Evidence of genetic heterogeneity within and between lesions was observed, both in terms of somatic mutations and copy number aberrations. The repertoires of somatic genetic aberrations found in the breast, ovarian, and pelvic-peritoneal lesions provided direct evidence in support of the distinct origin of the breast and ovarian cancers, and established that the pelvic-peritoneal implants were clonally related to the ovarian lesion. These observations were consistent with those obtained with immunohistochemical analyses employing markers to differentiate between carcinomas of the breast and ovary, including WT1 and PAX8. Our results on this case of a patient with BRCA1-mutant breast and ovarian cancer demonstrate that massively parallel sequencing may constitute a useful tool to define the relationship, clonality and intra-tumor genetic heterogeneity between primary tumor masses and their metastatic deposits in patients

    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.

A computed tomographic scan revealed the absence of mediastinal nodal involvement. Guided-needle aspiration cytology was inconclusive. A subsequent right thoracotomy was necessary to perform biopsy of these masses, which proved to be B-cell malignant lymphomas of the lung. This case represents a rare example of a primary low-grade B-cell pulmonary lymphoma of mucosa-associated lymphoid tissue, with its distinct clinicopathologic features.

    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.

    OBJECTIVES: Primary ovarian failure is a rare disorder, and approximately 90% of cases are of unknown etiology. The aim of this study was to search for mutations in NANOS3, a gene that was recently related to the etiology of primary ovarian failure, in a group of Brazilian women. METHODS: We screened for NANOS3 DNA variants in 30 consecutive women who were previously diagnosed with primary ovarian failure, of unknown etiology and compared the results with those from 185 women with normal fertility. The NANOS3 gene was amplified by polymerase chain reaction using pairs of specific primers and then sequenced. The resulting sequences were compared with control sequences available in the National Center for Biotechnology and Information database. RESULTS: No mutations in NANOS3 were found in primary ovarian failure patients, but four previously described polymorphisms were identified at a similar frequency in the control and primary ovarian failure groups. CONCLUSIONS: Mutations in NANOS3 were not associated with primary ovarian failure in the present cohort. PMID:28076512

    We report a very rare and successful surgery for primary malignant tumor of the sternum. A 73-year-old male, previously healthy, was admitted to our hospital because a chest computed tomography scan detected an abnormal shadow that suggested a sternal tumor destroying part of the sternum body. Aspiration needle biopsy demonstrated a primary sternal chondrosarcoma measuring 3 x 4 cm in diameter. The sternum below the second intercostal space was resected along with a 1-cm width of cartilage below the third rib on each side. Sternal reconstruction was performed with Composix mesh, titanium mesh, and Marlex mesh, using a right pectoralis major muscle flap translation. The patient was extubated just after surgery, and the postoperative course was uneventful. This procedure may be useful for repairing the detect after wide sternotomy.

    Background: An extremely rare primary mixed tumor occurring in left proximal femurs of a 47-year old female is reported. Case report: She had left hip pain for three months in April 2004. Radiological examinations revealed that a translucent expansive lesion in the left greater trochanter. She received the curettage of lesion and bone graft surgery. Curettage specimens were diagnosed as malignant mixed tumor, considered to be metastatic. Five months late the lesion recurred. She underwent obturator neurotomy plus total hip replacement of left hip. A long-term of more than ten years follow-up showed there were no evidence of disease recurrence or metastasis and no any signs of other tumor in her body. Discussion: The tumor contained myoepithelial component with positive immunostain of S-100 protein, p63, CK-pan, and vimentin, epithelial component confirmed by CK-pan, CK-LMW and cartilage, which indicated the tumor was a mixed tumor. Cellular atypia, relative high mitosis index, cartilage consistent with grade I chordrosarcoma, focal coagulative necrosis, and infiltration between trabeculae found in the tumor indicated that the tumor had a low grade malignant nature. During long-time follow-up there were no signs of any tumor found in the patient, which strongly suggested that the tumor be a primary one. PMID:26339414

    The purposes of this study were to evaluate the CT and MR findings of Krukenberg tumors and to compare them with those of primary ovarian tumors. This study included 20 patients with Krukenberg tumors and 65 patients with various primary ovarian tumors. CT/MR/both imaging studies were available in 15/1/4 patients with Krukenberg tumor and 31/10/24 patients with primary ovarian tumors, respectively. Imaging findings of the tumors were categorized into three subgroups: a solid mass with intratumoral cysts, a solid mass without intratumoral cysts, and a predominantly cystic mass. Among 32 Krukenberg tumors (bilateral in 12 patients), 22 were solid masses with intratumoral cysts, in 14 of which the wall of the intratumoral cysts showed apparently strong contrast enhancement on CT and/or MRI. Six Krukenberg tumors were solid masses without intratumoral cysts, and four were predominantly cystic masses. Imaging findings of 88 primary ovarian tumors (bilateral in 23 patients) were 5 solid masses with intratumoral cysts, 27 solid masses without intratumoral cysts, and 56 predominantly cystic masses. None of the five primary ovarian tumors with solid mass with intratumoral cysts demonstrated apparently strong contrast enhancement of the cyst wall. Krukenberg tumor should be suspected when one sees solid ovarian tumors containing well demarcated intratumoral cystic lesions, especially if the walls of those cysts demonstrate apparently strong contrast enhancement. 11 refs., 4 figs., 1 tab.

    A 30-year-old woman presented with recurrent acne lesions and progressing male-pattern baldness. Furthermore, she reported amenorrhea, weight loss, mucosal xerosis and dyspareunia since discontinuation of hormonal contraception 6 months earlier in order to conceive. Acne tarda and androgenetic alopecia of female pattern were diagnosed. Hormonal and immunologic serological and ultrasound examinations revealed an autoimmune hypergonadotropic primary ovarian insufficiency (POI) with no ovarian cysts but ovarian fibrosis with marked reduced follicle pool. Immediate ovarian stimulation and in vitro fertilization led to pregnancy and the patient gave birth to a healthy child. Though presenting with clinical findings similar to menopause, 50% of patients with POI exhibit varying and unpredictable ovarian function, and only 5-10% are able to accomplish pregnancy. Genetic disorders affect the X chromosome. In 14-30% of cases POI has been associated with autoimmunity. POI may occur after discontinuation of hormonal contraception, like in our case.

    Ovarian mature cystic teratomas (MCTs) rarely transform to primary primitive neuroectodermal tumors. This case report offers evidence that MCTs might have undetected microfoci of malignant neural tumors. We describe the case of a 12-year-old girl who presented with right-sided abdominal pain and distention. Intraoperative findings revealed a right ovarian MCT. However, pathology showed a 0.5-cm focus of malignant neural tumor within the 11-cm MCT. This patient will need close follow-up with a multidisciplinary team because the clinical implications of this transformation has yet to be defined.

    Immunocytology of ascitic fluid of a patient with ovarian cancer demonstrated reactivity with two tumor-associated monoclonal antibodies, AUA1 and HMFG2. AUA1 radiolabeled with 48.6 mCi /sup 131/I was given intraperitoneally. There was a reduction in the rate of reaccumulation of ascites. Cytology of recurrent ascites revealed reactivity with antibody HMFG2 but not AUA1. The patient was further treated intraperitoneally with 39.0 mCi /sup 131/I-labeled HMFG2. There has been no reaccumulation of ascites. It is concluded that antibody-guided irradiation may be an effective treatment of malignant ascites secondary to ovarian cancer. Furthermore, this case illustrates the specificity of antibody interactions in the mediation of therapeutic effect and the possibility of tumor selection after irradiation with a single monoclonal antibody. If specificity plays a role, all major specificities should be covered by an appropriate panel of radioactively labeled antibodies. It is recommended that for comprehensive therapy of malignant ascites secondary to ovarian cancer, a mixture of antibodies such as HMFG2 and AUA1 should be used.

    Risk-reducing salpingo-oophorectomy (RRSO) is an effective prophylactic procedure for women with mutations in BRCA1 or BRCA2 genes, both of which confer an increased lifetime risk for ovarian, tubal, peritoneal, and breast cancer. In addition to lowering this risk, RRSO also offers the opportunity to detect occult early-stage fallopian tube or ovarian carcinoma. The differential diagnosis of occult tubal/ovarian cancer includes a spectrum of benign tubal and ovarian alterations and also occult metastatic breast cancer, although only rare cases of the latter have been reported in RRSO. Neoadjuvant breast cancer chemotherapy may contribute to diagnostic difficulty due to treatment-induced cytologic alterations. With the aim of elucidating features which may help with differential diagnosis, this study reports the incidence and pathologic features of benign ovarian alterations, benign ovarian tumors, and occult primary and metastatic malignancies in prophylactic oophorectomies from 108 women with a BRCA mutation and from 35 women with other strong risk factors for hereditary breast/ovarian carcinoma. We direct particular emphasis on morphologic features of primary ovarian lesions that may mimic occult metastatic breast cancer. We also evaluate histologic alterations due to neoadjuvant breast cancer chemotherapy in the ovary and fallopian tube of patients who received such treatment immediately preceding RRSO. Comparison is made to ovarian metastases of breast cancer in our hospital-based population of breast cancer patients, none of whom underwent RRSO. Overall, 69% of RRSO patients had a personal history of breast cancer. Neoadjuvant breast cancer chemotherapy was administered in 15%. Occult primary carcinoma occurred in 7 (6.5%) BRCA patients (5 in fallopian tube, 1 in fallopian tube and ovary, 1 in ovary). Ovarian metastasis of breast cancer occurred in 1 (1%) BRCA patient undergoing RRSO and in up to a similar proportion (0.8%) of the hospital-based population of

    A tumor suppressor gene at 10q23.3, designated PTEN, encoding a dual-specificity phosphatase with lipid and protein phosphatase activity, has been shown to play a pivotal role in the pathogenesis of a variety of human cancers. A frequent loss of heterozygosity (LOH) at 10q is found in melanoma; however, little is known about the role of PTEN in the pathogenesis of a primary malignant melanoma derived from ovarian mature cystic teratoma, which is an extremely rare melanoma. This study examined the genetic alterations involved in the mitogen-activated protein kinase and phosphatidylinositol 3 kinase pathways in an ovarian malignant melanoma. A LOH analysis revealed hemizygous deletion around and in the PTEN gene not only in the ovarian melanoma but also in a mature cystic teratoma. Another case of ovarian mature cystic teratomas in the absence of melanoma also showed allelic loss of the PTEN region. To date, mutations of BRAF, NRAS, and KIT genes have been reported in malignant melanomas. In the present study, D816H and K558E mutations of the KIT gene were revealed in the melanoma arising from a mature cystic teratoma, but not in a mature cystic teratoma. No mutations of the BRAF and NRAS genes were found in the melanoma. These results indicate that LOH of the PTEN region is one of the molecular alterations of an ovarian mature cystic teratoma and a KIT mutation is an additional promotional event associated with the oncogenesis of a melanoma arising from an ovarian mature cystic teratoma.

  8. Restaging and Survival Analysis of 4036 Ovarian Cancer Patients According to the 2013 FIGO Classification for Ovarian, Fallopian Tube, and Primary Peritoneal Cancer.

    With the 2013 International Federation of Gynecology and Obstetrics (FIGO) staging for ovarian, fallopian tube, and primary peritoneal cancer, the number of substages changed from 10 to 14. Any classification of a malignancy should easily assign patients to prognostic groups, refer patients to individualized treatments, and allow benchmarking and comparison of patients and results between centers. The stage should reflect survival in particular. The objective of the study was to validate these requirements of the revised FIGO staging on a high number of ovarian cancer patients. Demographic, surgical, histological, and survival data from 4036 ovarian cancer patients were used in the analysis. Five-year survival rates (5YSR) and hazard ratios for the old and revised FIGO staging were calculated using Kaplan-Meier curves and Cox regression. A total of 1532 patients were assigned to new stages. Stages IA and IC1 had similar survival (5YSR, 87%); and stages IB, IC2, and IC3 had similar survival (5YSR, 75%-80%). Stage IIC was omitted, resulting in similar survival in stages IIA and IIB (5YSR, 61% and 65%). Of 1660 patients in stage IIIC, 79 were restaged: In 16 cases, IIIC was down-staged to IIIA1, as they had only been stage IIIC owing to lymph node metastases; and in 63 cases, IIIC was down-staged to IIIB, as they had lymph node metastases and abdominal tumor of less than 2 cm. The 5YSR in stage IIIC was unchanged (22%). Stage IV (5YSR, 14% ) was restaged as IVA (13%) and IVB (13%). Both were different from IIIC; P < 0.0001. With introduction of new substages, staging becomes more demanding. Second, as fewer patients are allocated to each substage, statistical power is diminished, resulting in uncertainty in the results. Despite this, and most importantly, the revised coding adequately reflects survival, as there was a clear graphical and statistical tendency for poorer survival with increasing stage.

    The prevalence of several paraneoplastic syndromes associated with ovarian cancer was determined from a clinicopathological study of 908 patients with primary ovarian malignancy in the North East Thames Region. The diversity and rarity of these manifestations are great and the explanation for them is difficult. Circumstantial evidence suggests that in some cases an autoimmune phenomenon is the most plausible cause.

    Malignant ovarian germ cell tumors (MOGCT) carry an excellent prognosis, and the treatment aims to achieve results with the least possible treatment-related morbidity. The aim of this study was to assess the outcomes of pediatric patients with MOGCT. Patients were treated according to their stage: surgery and surveillance for stage I; a modified bleomycin-etoposide-cisplatin (BEP) regimen for stages II (three cycles), III, and IV (three cycles) with surgery on residual disease. Seventy-seven patients were enrolled (median age 11.8 years), 26 with dysgerminoma (Dysg), 13 with immature teratoma and elevated serum alpha-fetoprotein levels (IT + AFP), and 38 with nondysgeminoma (Non-Dysg) staged as follows: 27 stage I, 13 stage II, 32 stage III, 5 stage IV. Among evaluable patients in stage I (5-year event-free survival [EFS] 72.1% [95% CI: 56.4-92.1%]; 5-year overall survival [OS] 100%), seven relapsed (three patients with Dysg and four patients with Non-Dysg) and were rescued with chemotherapy (plus surgery in three patients). Among the evaluable patients with stages II-IV, 48 (98%) achieved complete remission after chemotherapy ± surgery, one (IT + AFP, stage IV) had progressive disease. In the whole series (median follow-up 80 months), the 5-year OS and EFS were 98.5% (95% CI: 95.6-100%) and 84.5% (95% CI: 76.5-93.5%). We confirm the excellent outcome for MOGCT. Robust data are lacking on surgical staging, surveillance for Non-Dysg with stage I, the management of IT + AFP, and the most appropriate BEP regimen. As pediatric oncologists, we support the role of surveillance after proper surgical staging providing cases are managed by experts at specialized pediatric centers. © 2017 Wiley Periodicals, Inc.

    BACKGROUND The aim of this work was to analyze the diagnostic and prognostic value of serum human epididymis protein 4 (HE4) and Risk for Ovarian Malignancy Algorithm (ROMA) in epithelial ovarian cancer (EOC). METHODS Preoperative serum samples of 419 women (140 healthy controls, 131 ovarian benign cysts, 34 endometriosis, 114 EOC) were tested for CA125 and HE4 using fully automated methods (Abbott ARCHITECT) and validated cut-off values. RESULTS For the discrimination of benign masses from EOC, in pre-menopausal women the sensitivity and specificity were 92.3% and 59.4% for CA125, 84.6% and 94.2% for HE4, and 84.6% and 81.2% for ROMA while in post-menopausal women the sensitivity and specificity were 94.3% and 82.3% for CA125, 78.2% and 99.0% for HE4, 93.1% and 84.4% for ROMA. In patients with EOC, elevated CA125, HE4 and ROMA levels were associated with advanced FIGO stage, sub-optimally debulking, ascites, positive cytology, lymph node involvement and advanced age (all p≤0.05). Elevated HE4 and ROMA (both p≤0.01), but not CA125 (p=0.0579), were associated with undifferentiated tumours. In multivariable analysis, elevated HE4 and ROMA (all p≤0.05) were independent prognostic factors for shorter overall survival, disease free survival and progression free survival. CONCLUSIONS and IMPACT This study underlines the high specificity of HE4 in discriminating endometriosis and ovarian benign cysts from EOC and the high sensitivity of CA125 in detecting EOC. We demonstrated HE4 and ROMA as independent prognostic factors. Multicenter studies are needed to draw firm conclusions about the applicability of HE4 and ROMA in clinical practice. PMID:22028406

    Epithelial ovarian cancer (EOC) represents the most challenging of gynecological malignancies. Defective apoptosis is a major causative factor in the development and progression of cancer. The two important pathways of apoptosis are extrinsic death receptor pathway (Fas family) and intrinsic mitochondrial pathway (Bcl-2 family). In this study, differential protein expression of the major Fas family members (Fas, FasL, and FAP-1) and Bcl-2 family members (Bax, Bcl-2, and Bcl-X(L)) in benign versus malignant surface epithelial ovarian tumors was evaluated at the protein level by immunohistochemistry. The expression of these molecules was compared in 30 benign versus 35 malignant surface epithelial ovarian tumors. The findings of the present study showed that there was no significant difference in the expression of the Fas family members in benign and malignant ovarian tumors. However, benign tumors showed higher levels of anti-apoptotic Bcl-2 protein levels (p < 0.009), whereas malignant tumors showed higher levels of pro-apoptotic Bax (p < 0.001). In general, there was no significant difference in Bcl-X(L) protein levels. The observations made in the present study suggest that alterations in expression of the Fas family and the Bcl-2 family members occur and play a key role in the deregulated growth of epithelial ovarian cancer.

    To quantify and compare survival in women with malignant ovarian germ cell tumors (MOGCTs) in Norway before and after the introduction of cisplatin-based chemotherapy (around 1980), and to explore the association between different types of treatment and the development of a second cancer. We identified 351 patients diagnosed with MOGCTs from 1953 to 2009 in the Cancer Registry of Norway. Ovarian cancer-specific survival was calculated separately for patients diagnosed before and after 1980. Patients were divided into subgroups by histological subtype (pure dysgerminoma, malignant teratoma, other MOGCTs) and extent of disease (localized and metastatic). We estimated the cumulative incidence of a second cancer in 10-year MOGCT survivors. Kaplan-Meier estimates were used, and p<0.05 was considered significant. 20-Year ovarian cancer-specific survival increased from 59% (95% CI 51% to 66%) before 1980 to 88% (95% CI 83%-93%) thereafter. Significant improvement was observed in all subgroups. No second cancer was diagnosed in any of 31 10-year MOGCT survivors treated with surgery only; second cancer was diagnosed in 23 of 139 patients who underwent cytotoxic treatment (98 radiotherapy ± chemotherapy, 41 chemotherapy only; p=0.08). Patients aged >50 years had a significantly poorer ovarian cancer-specific survival than younger patients (HR=5.98, 95% CI 3.39-10.57) after adjustment for histological subtype and stage at presentation. Our results favor the treatment of patients with metastatic MOGCTs at large cancer centers. Today women with MOGCTs have an excellent prognosis if treated according to modern therapeutic principles. © 2013.

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

    114 biopsy specimens from 70 patients with ovarian carcinoma at all stages of disease were submitted for assessment of clonogenic capacity in agar. A highly significant correlation was found between agar clonogenicity and patient survival after biopsy. However, problems related to inherent tumour heterogeneity, quality of sample and tissue disaggregation indicate that this technique may have limited applicability in the routine assessment of patients. Only 41 biopsy specimens (36%) from 31 patients (44.3%) complied with the prerequisite criteria for agar clonogenic assessment, namely: (a) the confirmed presence of malignant cells in the biopsy, (b) the ability to prepare a single-cell suspension, and (c) adequate viable cell numbers for assay. Furthermore, although the dominant patterns of agar clonogenic growth could be identified and correlated with stage of disease, the heterogeneity in both initial clonogenic capacity and "self-renewal" capacity assessed by the ability of primary clones to propagate in liquid culture and reclone in agar was too inconsistent for the assay to be used as a prognostic index for the individual patient.

    Shadow cells are characteristic of pilomatricoma, although they have been described in other cutaneous and visceral neoplasms, particularly endometrioid adenocarcinomas of the female genital tract. We describe a metastasis of an ovarian endometrioid adenocarcinoma with shadow cells to the skin that was initially misinterpreted as a pilomatricoma. We compare the histology of the ovarian neoplasm to 21 pilomatricomas. This is the first reported case of a cutaneous metastasis of a visceral neoplasm mimicking a primary pilomatrical neoplasm.

    2011-01-01

    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, chemiotherapy 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 lymphnode 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.

    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.

    We previously developed a new plasma amino acid profile-based index (API) to detect ovarian, cervical, and endometrial cancers. Here, we compared API to serum cancer antigen 125 (CA125) for distinguishing epithelial ovarian malignant tumors from benign growths. API and CA125 were measured preoperatively in patients with ovarian tumors, which were later classified into 59 epithelial ovarian cancers, 21 epithelial borderline malignant tumors, and 97 benign tumors including 40 endometriotic cysts. The diagnostic accuracy and cutoff points of API were evaluated using receiver operating characteristic (ROC) curves. The area under the ROC curves showed the equivalent performance of API and CA125 to discriminate between malignant/borderline malignant and benign tumors (both 0.77), and API was superior to CA125 for discrimination between malignant/borderline malignant lesions and endometriotic cysts (API, 0.75 vs. CA125, 0.59; p < 0.05). At the API cutoff level of 6.0, API and CA125 had equal positive rates of detecting cancers and borderline malignancies (API, 0.71 vs. CA125, 0.74; p = 0.84) or cancers alone (API, 0.73 vs. CA125, 0.85; p = 0.12). However, API had a significantly lower detection rate of benign endometriotic cysts (0.35; 95 % CI, 0.21-0.52) compared with that of CA125 (0.65; 95 % CI, 0.48-0.79) (p < 0.05). API is an effective new tumor marker to detect ovarian cancers and borderline malignancies with a low false-positive rate for endometriosis. A large-scale prospective clinical study using the cutoff value of API determined in this study is warranted to validate API for practical clinical use.

    Malignant melanoma, as the name implies, is a malignant tumor of melanocytes, found in the skin, eyes, meningeal lining and the mucosal epithelium of the aero-digestive and genitourinary tracts. Malignant melanoma is typically skin malignancy, which rarely presents at extracutaneous site. Here we present a rare case of primary retroperitoneal melanoma and review the findings in comparison with other cases described in literature.

    Platelet-derived growth factor B (PDGF-B) and nestin have been suggested to be useful in the assessment of neoangiogenesis in malignant ovarian masses. We aimed to investigate a possible association of these markers with newly formed microcapillaries and perivascular cells in ovarian tumors. Microvessel density (MVD) and pericytes were studied in 82 women with ovarian neoplasms, including 7 benign cysts, 7 borderline masses, 64 epithelial ovarian cancers and 4 other malignant ovarian tumors. Immunohistochemical staining included antibodies to CD34, PDGF-B and nestin. Median values of CD34-positive and nestin-positive MVD were: 24,5 (range:17-32) and 21 (range: 12-31), respectively. No significant correlation between intratumoral CD-34 positive MVD and nestin-positive MVD was found. Benign and borderline lesions more frequently than malignant tumors displayed low or medium values of nestin-positive MVD (p = 0.01). Histological grading of malignant tumors was associated with nestin-positive MVD (p = 0.01). Nestin expression in tumor cells was not correlated with tumor grade or histological subtype. PDGF-B expression was found in tumor microves-sels in 72% of cases (59/82). High expression of PDGF in pericapillary cells was strongly associated with high expression of this marker in cancer cells (p = 0.007). Significant correlations between PDGF-B and nestin expression in malignant tumor microvessels were also found (p = 0.04). Nestin and PDGF-B expressions were strongly associated with high grade tumors when compared to low grade or benign masses. We conclude that the assessment of PDGF-B and nestin-positive MVD could be used to identify only highly active, angiogenic malignant ovarian masses, where tumor vasculature is formed.

    ABSTRACT The emerging role of the cancer cell-immune cell interface in shaping tumorigenesis/anticancer immunotherapy has increased the need to identify prognostic biomarkers. Henceforth, our primary aim was to identify the immunogenic cell death (ICD)-derived metagene signatures in breast, lung and ovarian cancer that associate with improved patient survival. To this end, we analyzed the prognostic impact of differential gene-expression of 33 pre-clinically-validated ICD-parameters through a large-scale meta-analysis involving 3,983 patients (‘discovery’ dataset) across lung (1,432), breast (1,115) and ovarian (1,436) malignancies. The main results were also substantiated in ‘validation’ datasets consisting of 818 patients of same cancer-types (i.e. 285 breast/274 lung/259 ovarian). The ICD-associated parameters exhibited a highly-clustered and largely cancer type-specific prognostic impact. Interestingly, we delineated ICD-derived consensus-metagene signatures that exhibited a positive prognostic impact that was either cancer type-independent or specific. Importantly, most of these ICD-derived consensus-metagenes (acted as attractor-metagenes and thereby) ‘attracted’ highly co-expressing sets of genes or convergent-metagenes. These convergent-metagenes also exhibited positive prognostic impact in respective cancer types. Remarkably, we found that the cancer type-independent consensus-metagene acted as an ‘attractor’ for cancer-specific convergent-metagenes. This reaffirms that the immunological prognostic landscape of cancer tends to segregate between cancer-independent and cancer-type specific gene signatures. Moreover, this prognostic landscape was largely dominated by the classical T cell activity/infiltration/function-related biomarkers. Interestingly, each cancer type tended to associate with biomarkers representing a specific T cell activity or function rather than pan-T cell biomarkers. Thus, our analysis confirms that ICD can serve as a

    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.

    Carcinoid heart disease, caused by primary ovarian carcinoid tumour, is a rare form of valvular heart disease. This form of heart disease usually presents with symptoms of right-sided valvular dysfunction, ultimately leading to right-sided heart failure. This entity is unique as it develops in the absence of liver metastasis. We report a case of 75 year-old woman with primary ovarian carcinoid tumour who presented with symptoms of severe right-sided heart failure and successfully underwent pulmonic and tricuspid valve replacement along with a right ventricular (RV) outflow patch enlargement. This patient later underwent uneventful resection of the primary ovarian carcinoid tumour, with complete resolution of her symptoms.

    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

    A 60-year-old male patient with hypertension was referred to our hospital because of insufficient blood pressure control (190/98 mmHg) and to rule out secondary hypertension. A computed tomography scan revealed no adrenal tumor but a large liver mass (5 x 5 cm), and magnetic resonance imaging showed a high signal intensity lesion on the T2-weighted image. Twenty-four hour urinary excretion of catecholamine metabolites was markedly increased, although a 123I-metaiodobenzyl guanidine (MIBG) scintigram failed to show accumulation in the hepatic mass, and no difference was noted between the catecholamine concentration in the tumor-drainage vein and that obtained from the vein draining from the non-tumor area. Liver biopsy did show features compatible with pheochromocytoma (i.e., chromogranin A-positive cells). Transcatheter arterial embolization of the liver tumor was conducted and resulted in a marked (50%) decrease in the 24-h urine normetanephrine excretion. Several metastatic foci were noted in the spinal bone and transcatheter arterial embolization (TAE) was also conducted with successful results. Thus, we experienced a case of primary malignant hepatic pheochromocytoma with negative 123I-MIBG scanning.

    Distinguishing malignant peritoneal mesothelioma (MPM) from serous carcinoma involving the peritoneum remains a diagnostic challenge, particularly in small biopsy and cytology specimens. In this distinction, PAX8 expression has been regarded as a specific marker of serous carcinoma. In addition, BAP1 loss is reportedly specific to MPM, in the distinction from both benign mesothelial lesions and ovarian serous tumors (OSTs). Using immunohistochemistry, we examined PAX8 and BAP1 expression in 27 MPMs, 25 cases of benign mesothelium, and 45 OSTs. Five MPMs were PAX8 (5/27, 18%), while 8 cases of benign mesothelium expressed PAX8 (8/25, 32%). PAX8 expression in mesothelium was significantly more common in women than in men (P=0.01). Sixteen MPMs exhibited BAP1 loss (16/25, 64%), while BAP1 was retained in all benign mesothelium and all OSTs. All cases of PAX8 mesothelium were negative for expression of estrogen receptor. These data show that PAX8 is expressed in both benign and malignant mesothelium, and that BAP1 loss is highly specific for MPM, in the differential with both benign mesothelial proliferations and OTSs. These results also have implications for primary diagnosis and for pathologic staging of OST. Caution should be applied when PAX8 expression is used to distinguish mesothelial and serous proliferations, and BAP1 loss may be confirmatory in cases where mesothelioma is favored.

    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. The high temperature requirement factor A3 (HtrA3) is a serine protease homologous to bacterial HtrA. Four human HtrAs have been identified. HtrA1 and HtrA3 share a high degree of domain organization and are downregulated in a number of cancers, suggesting a widespread loss of these proteases in cancer. This study examined how extensively the HtrA (HtrA1-3) proteins are downregulated in commonly used cancer cell lines and primary ovarian tumors.Methods. RT-PCR was applied to various cancer cell lines (n=17) derived from the ovary, endometrium, testes, breast, prostate, and colon, and different subtypes of primary ovarian tumors [granulosa cell tumors (n=19), mucinous cystadenocarcinomas (n=6), serous cystadenocarcinomas (n=8)] and normal ovary (n = 9). HtrA3 protein was localized by immunohistochemistry.Results. HtrA3 was extensively downregulated in the cancer cell lines examined including the granulosa cell tumor-derived cell lines. In primary ovarian tumors, the HtrA3 was significantly lower in serous cystadenocarcinoma and granulosa cell tumors. In contrast, HtrA1 and HtrA2 were expressed in all samples with no significant differences between the control and tumors. In normal postmenopausal ovary, HtrA3 protein was localized to lutenizing stromal cells and corpus albicans. In serous cystadenocarcinoma, HtrA3 protein was absent in the papillae but detected in the mesenchymal cyst wall.Conclusion. HtrA3 is more extensively downregulated than HtrA1-2 in cancer cell lines. HtrA3, but not HtrA1 or HtrA2, was decreased in primary ovarian serous cystadenocarcinoma and granulosa cell tumors. This study provides evidence that HtrA3 may be the most relevant HtrA associated with ovarian malignancy.

    Malignant primary pediatric hepatic tumors (MPPHTs) are rare and account for approximately 1% of all childhood malignancies. In recent years, liver transplantation has emerged as a viable treatment options for select patients with MPPHTs. We performed a single-center retrospective study using a prospective database to compare outcomes of pediatric liver transplant recipients, with and without cancer, between January 2000 and December 2014. One hundred fifty-three children underwent 173 liver transplantations during the study period. Of these, 21 (12%) children received 23 (13.3%) transplants for unresectable MPPHTs: 16 hepatoblastomas (HBs), 3 embryonal cell sarcomas (ECS), and 2 hepatocellular carcinomas (HCCs). There was no significant difference in 1-, 3-, and 10-year patient and graft survival rates between MPPHT and non-MPPHT patients (95.2%, 81.2%, 81.2%, and 95.2%, 72,2%, 72.2% for MPPHT vs 92.7%, 89.8%, 87.6% and 85.4%, 81.1%, 75% for the non-MPPHT group, respectively) (p > 0.05). Rates of 1-, 5-, and 10-year disease-free survival for MPPHT patients were 76%, 76%, and 76%, respectively. Median age at transplantation for MPPHT patients was 3.1 years (range 58 days to 17 years), median listing time was 81 days, and median wait list time was 15 days. Eight (38%) children had 2 tumors or more and 4 of 16 (25%) HB patients had metastatic disease at presentation. All children received neoadjuvant treatment, with radiographic response in 19 of 21 patients. Presence of metastatic HB at presentation, International Society of Pediatric Oncology Epithelial Liver (SIOPEL) high risk status, and persistently elevated alpha fetoprotein levels after neoadjuvant chemotherapy might be risk factors for tumor recurrence and decreased survival. Liver transplantation is an excellent option for select patients with unresectable MPPHTs, with outcomes comparable to those after transplantation for nonmalignant causes.

    Multiple primary malignant neoplasm is the occurrence of a second primary malignancy in the same patient within 6 months of the detection of first primary (synchronous), or 6 months or more after primary detection (metachronous). Multiple primary malignant neoplasms are not very frequently encountered in clinical practice. The relative risk for a second primary malignancy increases by 1.111-fold every month from the detection of the first primary malignancy in any individual. We present 2 patients treated for carcinoma of the breast who developed a metachronous primary malignancy in the stomach to highlight the rare occurrence of multiple primary malignant neoplasms. These tumors were histologically dissimilar, with distinct immunohistochemical parameters. The importance lies in carefully identifying the second primary malignancies, not dismissing them as metastases, and treating them accordingly. PMID:24444270

    Peritoneal malignant mesothelioma is a rare and extremely aggressive tumor that is sometimes difficult to diagnose. We report two cases of metastatic malignant peritoneal mesothelioma. In one case, malignant metastatic cells were identified in cervical lymph nodes while in the other case, the cells were found in the liver. In both cases, metastases were identified before discovering the primary tumor. This led to the misdiagnosis of carcinoma of unknown origin. Nevertheless, the histological and immuno-histochemical patterns were typical of malignant mesothelioma. Regarding metastasis of unknown origin, a differentiation of epithelioid peritoneal malignant mesothelioma and adenocarcinoma proved to be difficult. Therefore, we discuss the diagnostic usefulness of immuno-histochemical mesothelioma markers.

    It can be difficult to differentiate diffuse malignant peritoneal mesothelioma (DMPM) from reactive mesothelial hyperplasia (RMH) or peritoneal dissemination of gynecologic malignancies, such as epithelial ovarian cancer (EOC), which cause a large amount of ascites. Detection of the homozygous deletion of p16/CDKN2A (p16) by fluorescence in situ hybridization (FISH) is an effective adjunct in the diagnosis of malignant pleural mesothelioma. The aim of this study was to investigate the ability of the p16 FISH assay to differentiate DMPM from RMH and EOC. p16 FISH was performed in 28 DMPMs (successful in 19), 30 RMHs, and 40 EOC cases. The cutoff values of p16 FISH were more than 10% for homozygous deletion and more than 40% for heterozygous deletion. According to the above criteria, nine (47.4%) of 19 successful DMPM cases were homozygous deletion positive, and three (15.8%) of 19 were heterozygous deletion positive, whereas all RMH cases were negative for the p16 deletion. In all four major histologic subtypes of EOC, neither p16 homozygous nor heterozygous deletions were detected. To differentiate DMPM from RMH or EOC, the sensitivity of the p16 homozygous deletion was 32% (9/28), and the specificity was 100%. Our study suggests that p16 FISH analysis is useful in differentiating DMPM from RMH and EOC when homozygous deletion is detected. Copyright© by the American Society for Clinical Pathology.

    This study aimed to assess the diagnostic value of vimentin expression in differentiating endometrioid adenocarcinoma of primary uterine corpus and ovarian origin. Immunohistochemical analyses for the expression of vimentin in tumoral epithelial cells were performed on 149 endometrioid adenocarcinomas wherein the primary sites were not in question, including whole tissue sections of 27 carcinomas of uterine corpus origin (and no synchronous ovarian tumor), 7 carcinomas of ovarian origin (and no synchronous uterine corpus tumor) and a tissue microarray (TMA) containing 91 primary uterine corpus and 24 primary ovarian carcinomas. We also assessed 15 cases that synchronously involved the uterine corpus and ovary, 15 cases of metastasis to organs/tissues other than uterine corpus or ovary as well as 7 lymph node metastases. Vimentin was negative in 97% (30/31) of primary ovarian carcinomas. In contrast, 82% (97/118) of primary uterine corpus carcinomas were vimentin-positive. Vimentin expression was discordant in 53% of synchronous tumors. The sensitivity and specificity of negative vimentin staining in predicting an ovarian primary were 97% and 82%, respectively, whereas parallel values for positive vimentin staining in predicting a primary uterine tumor were 82% and 97%, respectively. The pattern of vimentin expression in all cases was maintained in their respective regional lymph nodes and distant metastases. In conclusion, ovarian and uterine corpus endometrioid adenocarcinomas have different patterns of vimentin expression. If validated in larger and/or different data sets, these findings may have diagnostic value in distinguishing metastatic lesions from double primary tumors involving both sites.

    Primary ovarian carcinoids and metastatic tumors share similar morphologic features. Metastatic carcinoids must be excluded from primary ones for prognostic and therapeutic reasons. Gastrointestinal neuroendocrine (carcinoid) tumors are much more common with the majority arising from small intestine and appendix. The aim of this study is to evaluate the role of immunohistochemistry for CDX2 in differentiating primary ovarian from metastatic carcinoids of primary gastrointestinal origin. Thirty primary pure ovarian carcinoids, 16 primary ovarian carcinoids arising in association with benign teratomas, 10 ovarian carcinoids metastatic from primary gastrointestinal tract and 70 gastrointestinal neuroendocrine tumors were studied for the expression of CDX2 by immunohistochemistry. CDX2 expression revealed that 40 (57.1%) of 70 cases of gastrointestinal carcinoids and 9 (90%) of 10 ovarian metastatic carcinoids showed positive nuclear staining (diffuse or focal). On the other hand, 3 (18.8%) of 16 primary carcinoids with teratomatous elements showed weak positivity. Among the 70 gastrointestinal carcinoids, CDX2 was positive in 38 (90.5%) of 42 cases in the duodenum, small intestine, appendix, and only in 2 (11.8%) of 17 cases of colorectal carcinoids and none of the 11 cases in the stomach. It is concluded that CDX2 may be a useful marker to distinguish primary ovarian carcinoid from metastasis from small intestinal and appendiceal neuroendocrine tumors.

    Ovarian carcinomas exhibit extensive heterogeneity, and their etiology remains unknown. Histological and genetic evidence has led to the proposal that low grade ovarian serous carcinomas (LGOSC) have a different etiology than high grade carcinomas (HGOSC), arising from serous tumours of low malignant potential (LMP). Common regions of chromosome (chr) 3 loss have been observed in all types of serous ovarian tumours, including benign, suggesting that these regions contain genes important in the development of all ovarian serous carcinomas. A high-density genome-wide genotyping bead array technology, which assayed >600,000 markers, was applied to a panel of serous benign and LMP tumours and a small set of LGOSC, to characterize somatic events associated with the most indolent forms of ovarian disease. The genomic patterns inferred were related to TP53, KRAS and BRAF mutations. An increasing frequency of genomic anomalies was observed with pathology of disease: 3/22 (13.6%) benign cases, 40/53 (75.5%) LMP cases and 10/11 (90.9%) LGOSC cases. Low frequencies of chr3 anomalies occurred in all tumour types. Runs of homozygosity were most commonly observed on chr3, with the 3p12-p11 candidate tumour suppressor region the most frequently homozygous region in the genome. An LMP harboured a homozygous deletion on chr6 which created a GOPC-ROS1 fusion gene, previously reported as oncogenic in other cancer types. Somatic TP53, KRAS and BRAF mutations were not observed in benign tumours. KRAS-mutation positive LMP cases displayed significantly more chromosomal aberrations than BRAF-mutation positive or KRAS and BRAF mutation negative cases. Gain of 12p, which harbours the KRAS gene, was particularly evident. A pathology review reclassified all TP53-mutation positive LGOSC cases, some of which acquired a HGOSC status. Taken together, our results support the view that LGOSC could arise from serous benign and LMP tumours, but does not exclude the possibility that HGOSC may derive

    To study pregnancy chance in adult women with classic galactosemia and primary ovarian insufficiency. Despite dietary treatment, >90% of women with classic galactosemia develop primary ovarian insufficiency, resulting in impaired fertility. For many years, chance of spontaneous conception has not been considered, leading to counseling for infertility. But an increasing number of reports on pregnancies in this group questions whether current counseling approaches are correct. Multicenter retrospective observational study. Metabolic centers. Adult women (aged >18 y) with confirmed classic galactosemia and primary ovarian insufficiency were included. Participants and medical records were consulted to obtain study data in a standardized manner with the use of a questionnaire. Conception opportunities, time to pregnancy, pregnancy outcome, hormone replacement therapy use, fertility counseling, and the participants' vision of fertility were evaluated. Potential predictive factors for increased pregnancy chance were explored. Eighty-five women with classic galactosemia and primary ovarian insufficiency participated. Twenty-one women actively attempted to conceive or did not take adequate contraceptive precautions. Of these 21 women, nine became pregnant spontaneously (42.9%). This was higher than reported in primary ovarian insufficiency due to other causes (5%-10%). After a period of 12 months, a cumulative proportion of 27.8% of couples had conceived, which increased to 48.4% after 24 months and 61.3% after 27 months. Predictive factors could not be identified. A considerable miscarriage rate of 30% was observed (6 of 20 pregnancies). Although a substantial proportion of women expressed a child-wish (n = 28/53; 52.8%), the vast majority of participants (n = 43/57; 75.4%) considered conceiving to be highly unlikely, owing to negative counseling in the past. The pregnancy rate in women with classic galactosemia and primary ovarian insufficiency was higher than for

    Carcinoid tumor of the ovary is uncommon. We herein report a very rare case of primary ovarian carcinoid tumor with aggressive histology and an unusual immunophenotype. A 21-year-old woman presented with a palpable abdominal mass. Computed tomographic scan revealed a large, extensively necrotic solid mass in the left ovary. The patient underwent a left salpingo-oophorectomy. Grossly, the left adnexa showed a large, vaguely lobulated ovarian tumor measuring 22×15×13 cm. Histologically, the tumor had a readily identifiable neuroendocrine growth pattern, but some areas showed solid growth pattern associated with mild nuclear pleomorphism and multiple foci of punctate necrosis. Furthermore, mitotic figures were recognized in 8 per 10 high-power fields, and a few foci of large coagulative tumor necrosis were also noted. In addition, the tumor tissue exhibited uniform, strong nuclear β-catenin immunoreactivity, indicating the nuclear accumulation of β-catenin in the individual tumor cells. In summary, we described the first case of primary ovarian carcinoid tumor with loss of neuroendocrine growth pattern, increased mitotic activity and large areas of coagulative tumor necrosis. According to the WHO classification of pulmonary carcinoid tumor, this case may be classified as "atypical" carcinoid. However, currently, no primary ovarian atypical carcinoid exists in the classification system. Due to its rarity, there are no established diagnostic criteria and clinical data on patient outcomes for ovarian carcinoid tumors with aggressive histology. Additional reports are clearly necessary. We also showed for the first time the nuclear accumulation of β-catenin in carcinoid tumor cells, suggestive of a role for β-catenin in the tumorigenesis of ovarian atypical carcinoid tumor or its aggressive histology.

    For 1950-80, 194 ovarian cancer cases were ascertained among the 70,030 females of the Radiation Effects Research Foundation's Life-Span Study E-85 sample, and 106 autopsied cases with benign ovarian neoplasms were ascertained among all 3046 autopsies performed in the same sample. On the basis of microscopic review, 66% of the cancer and 84% of the benign tumor cases were classified by histologic type. The age-adjusted ovarian cancer incidence rates showed a statistically significant increase with increased exposure dose, both in the entire exposed group (P less than .01) and in the microscopically reviewed subset (P less than .01). This dose response was only significant (P less than .01) in the latter half of the study period, 1965-80. The radiation effect was higher in the younger age group at the time of the bomb (ATB) for the specific attained age or was adjusted for attained age. In general, relative risk (greater than or equal to 100 rad vs. 0 rad) did not differ by attained age, except for the youngest age group, less than 20 years old ATB, where the relative risk tended to decrease with increased attained age, although cases were few in number and follow-up study was necessary. Estimated minimum latent period for radiation-induced ovarian cancer seemed to be 15-20 years. The proportion of autopsied cases with benign ovarian tumor increased with increasing exposure dose, both in the entire series of cases (P less than .05) and in the microscopically reviewed subset. Statistical significance, however, was not achieved in the latter group. The distribution of histologic types of both cancer and benign tumor of the ovary did not vary significantly with radiation dose.

    In numerous patients with multiple primary malignant neoplasms, it is difficult to determine whether the mass is benign or malignant, and the method to treat these lesions is controversial. For patients with a history of cancer, a point of high-risk for the development of a second primary tumor occurs following a 10-year gap. To the best of our knowledge, to date, there has been no large clinical trial to observe the appropriate method to manage the lesions in patients with multiple primary malignant neoplasms. The present study reports the case of a patient who was initially diagnosed with rectal cancer, treated with Dixon's rectectomy and post-operative chemotherapy. The patient's disease was evaluated as complete response following these treatments. However, the patient then presented with bladder cancer and underwent transurethral resection of the bladder tumor, again achieving a complete response. The patient more recently presented with hepatocellular carcinoma, which developed from an unexplained mass in the liver. The patient underwent partial liver resection and to date, has achieved a complete response. The management of masses of unknown malignancy is also discussed. The current case provides useful insight for future research in this field.

    Ovarian carcinomatosis poses a dilemma for the surgeon. When resecting colon for tumor invasion, one must decide between diversion and primary anastomosis (PA). We examined the National Surgical Quality Improvement Program to determine whether PA associated with more complications than ostomy. The National Surgical Quality Improvement Program dataset was queried for patients with ovarian carcinomatosis between 2007 and 2012. Current Procedural Terminology codes were used to further identify patients undergoing colectomy with PA or ostomy. Logistic regression was used to evaluate 30-day morbidity and mortality. The 1013 ovarian carcinomatosis patients who underwent elective colon surgery were divided into primary repair (n = 453, 43.5%) or ostomy (n = 586, 56.5%) groups. Preoperative demographics were similar; however, ostomy patients had more severe preoperative laboratory derangements. The 30-day mortality and postoperative transfusion requirements were higher in the ostomy group. On multivariate analysis controlling for confounders, the differences were no longer significant. In conclusion, 30-day mortality and postoperative complications were increased in the ostomy group. Given the laboratory derangements in this group, this may reflect tendency to allocate ostomies to more ill patients. Primary repair in a selected population does not worsen outcomes. Prospective evaluation would help determine the impact of PA in the ovarian carcinomatosis population.

    Objective Cytoreductive surgery for ovarian cancer has higher rates of postoperative complication than neoadjuvant chemotherapy followed by surgery. If patients at high risk of postoperative complication were identified preoperatively, primary therapy could be tailored. Our objective was to develop a predictive model to estimate the risk of major postoperative complication after primary cytoreductive surgery among elderly ovarian cancer patients. Methods Patients who underwent primary surgery for ovarian cancer between 2005-2013 were identified from the National Surgical Quality Improvement Project. Patients were selected using primary procedure CPT codes. Major complications were defined as grade 3 or higher complications on the validated Claviden-Dindo scale. Using logistic regression, we identified demographic and clinical characteristics predictive of postoperative complication. Results We identified 2,101 ovarian cancer patients of whom 35.9% were older than 65. Among women older than 65, the rate of major postoperative complication was 16.4%. Complications were directly associated with preoperative laboratory values (serum creatinine, platelets, white blood cell count, hematocrit), ascites, white race, and smoking status, and indirectly associated with albumin. Our predictive model had an area under receiver operating characteristic curve of 0.725. In order to not deny patients necessary surgery, we chose a 50% population rate of postoperative complication which produced model sensitivity of 9.8% and specificity of 98%. Discussion Our predictive model uses easily and routinely obtained objective preoperative factors to estimate the risk of postoperative complication among elderly ovarian cancer patients. This information can be used to assess risk, manage postoperative expectations, and make decisions regarding initial treatment. PMID:26432038

    Advanced ovarian cancers are highly metastatic due to frequent peritoneal dissemination, resulting in dismal prognosis. Here we report the functions of cancer-derived extracellular vesicles (EVs), which are emerging as important mediators of tumour metastasis. The EVs from highly metastatic cells strongly induce metastatic behaviour in moderately metastatic tumours. Notably, the cancer EVs efficiently induce apoptotic cell death in human mesothelial cells in vitro and in vivo, thus resulting in the destruction of the peritoneal mesothelium barrier. Whole transcriptome analysis shows that MMP1 is significantly elevated in mesothelial cells treated with highly metastatic cancer EVs and intact MMP1 mRNAs are selectively packaged in the EVs. Importantly, MMP1 expression in ovarian cancer is tightly correlated with a poor prognosis. Moreover, MMP1 mRNA-carrying EVs exist in the ascites of cancer patients and these EVs also induce apoptosis in mesothelial cells. Our findings elucidate a previously unknown mechanism of peritoneal dissemination via EVs. PMID:28262727

Ain Shams University, during the period from May 1994 to October 1999. Six patients were diagnosed with dysgerminoma, six with immature teratoma and four with endodermal sinus tumor. Only seven cases were primarily managed at the unit and were subjected to proper surgical staging as required by FIGO (two in each of the stages IC, IIC and IIIA and one in stage IV). However, the remaining nine cases were referred to the unit, six after having unilateral salpingo-oophorectomy and no surgical staging, one patient after total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH+BSO), and one with recurrent dysgerminoma in the retroperitoneum and mediastinum following suboptimal treatment. None of these cases were surgically re-explored and all including the first six cases were given the standard BEP chemotherapy for 4-6 courses (mean 5.8). Follow-up ranged from 7-72 months (mean 30.5). All patients are alive without any evidence of disease recurrence except for one patient with a stage IIIA immature teratoma who had a local and distant recurrence and is undergoing second-line chemotherapy. All patients have their menstrual function preserved except for three patients; one having 46,XX pure gonadal dysgenesis with a preoperative FSH level of 120 U/l and the eldest two patients having a TAH+BSO as they had completed their families. Three patients are currently pregnant. In view of the high chemosensitivity and curability of ovarian germ cell tumors and their occurrence in young patients, every effort should be made to preserve one ovary and the uterus for future reproduction even in advanced cases.

    The current paper summarizes relevant recent research on the high risk of recurrence, multiple skin cancers and second primary cancers in the growing number of people with a history of skin cancer; the ultimate purpose is to better assess the burden of malignancy following skin cancer. A number of challenges exist in identifying and tracking both melanoma and non-melanoma skin cancer (NMSC) cases. Most jurisdictions do not routinely track NMSC cases and, even if they do, it is customary to only include the first diagnosis. There are variable rules for counting multiple melanoma cancers, and recurrences are not considered for either major type of skin cancer. Applying insights from recent studies of this issue to Canadian cancer statistics would increase reported diagnoses of NMSC by about 26% and melanoma by 10% in this country. This approach to a fuller assessment of the burden of skin cancers has been called a "diagnosis-based incidence approach" as compared with a "patient-based incidence approach". A further issue that is not usually taken into account when assessing the burden of skin cancers is the 20% to 30% elevated risk of noncutaneous second primary cancers following a primary skin tumour. In summary, individuals with skin cancer are subject to a high risk of recurrence, multiple skin cancers and second primary cancers. This burden should be a special concern in the large and growing pool of individuals with a history of skin cancer, as well as among prevention planners.

    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

    Most endocervical adenocarcinomas ( approximately 90%) are high-risk human papillomavirus (HPV)-related neoplasms, with the remainder being unrelated to HPV; both types infrequently metastasize to the ovaries. Clinicopathologic features of 29 cases of synchronous and metachronous endocervical and ovarian tumors (26 HPV-related, 3 unrelated to HPV) were analyzed. In 18 cases, the cervical tumors were clearly invasive; these included 5 clinically evident tumors diagnosed before the ovarian metastases (immediately preoperatively to 7 y), 11 clinically unsuspected tumors diagnosed concurrently in specimens obtained for evaluation of ovarian/pelvic masses, 1 case with concurrent clinically evident cervical and ovarian masses, and 1 clinically occult tumor diagnosed subsequent to the ovarian metastasis. In 11 cases, the cervical tumors were more limited; these included 5 tumors comprised predominantly of adenocarcinoma in situ with small foci of superficial invasion ("microinvasive carcinomas") diagnosed before the ovarian metastases (3 mo to 7 y) and 6 tumors comprised of extensive adenocarcinoma in situ lacking unequivocally recognizable stromal invasion diagnosed before (9 mo to 7 y, n=4), concurrently with (n=1), or subsequent to (n=1) the ovarian metastases. Fifteen cervical tumors involved lower uterine segment corpus endometrium or endomyometrium, including 4 tumors that were minimally invasive or not recognizably invasive in the cervix. The ovarian tumors ranged in size from 2.1 to 30.0 cm (mean/median=12.7/13.5); they were unilateral in 19 cases (65.5%) and 12 of these were unilateral and 10 cm or greater. In 26 cases, including the 19 unilateral tumors, the ovarian tumors exhibited "borderlinelike," confluent glandular, cribriform, and/or villoglandular patterns simulating primary ovarian atypical proliferative (borderline) tumors or well-differentiated carcinomas; these patterns were pure in 24 and admixed with minor infiltrative foci in 2.

    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.

    Carcinoid heart disease (CHD) commonly occurs in association with primary gastrointestinal tract carcinoid tumors with hepatic metastases. Unlike primary gastrointestinal tract carcinoid tumors, primary ovarian carcinoid tumors may cause CHD without hepatic metastases, accounting for only 0.3 % of all carcinoid tumors. Only 37 cases of CHD from primary ovarian carcinoid tumors have been reported. We present a case of CHD in which tricuspid valve thickening and shortening led to reduced valve mobility with the resulting severe tricuspid regurgitation. Considering these characteristics of an abnormal tricuspid valve, we suspected CHD, but prosthetic valve replacement was performed without sufficient systemic examination before surgery. Two years after valve replacement, the patient underwent excision of a mass in the lower abdomen, which was diagnosed as an ovarian carcinoid tumor by histopathological examination. The patient has been observed for more than 3 years after tricuspid valve replacement. She has not experienced bioprosthetic valve leaflet degeneration or dysfunction, although it has been reported that bioprosthetic valves may degenerate in patients with carcinoid tumors. Sufficient systemic examinations should be performed to explore the cause of disease.

    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.

    The authors present a case of a gentleman in his 70s who was referred to the gastroenterology outpatient clinic with dysphagia. An oesophagogastroduodenoscopy was performed which showed a polypoidal black coloured mass in the oesophagus. Endoscopic biopsies confirmed malignant melanoma. Further staging investigations were organised to assess suitability for surgery which revealed a mass in the sigmoid colon. Subsequent colonoscopy and biopsy confirmed adenocarcinoma. As this was an unusual case to associate these two malignancies at the same time, there was no ideal or recognised management plan available. Different treatment options were considered and a consensus was developed regarding best surgical approach but due to the lapse in time a repeat staging CT scan was organised which unfortunately now demonstrated lymph node metastasis. Patient was managed conservatively from this point onwards and he died 12 months later. PMID:22689833

    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.

    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.

    In the current study, the authors attempted to describe the incidence, most common sites, and mortality of second primary malignancies among survivors of common cancers. The authors identified patients aged ≥18 years who were diagnosed with a primary malignancy from the 10 most common cancer sites (prostate, breast, lung, colon, rectum, bladder, uterus, kidney, melanoma, and non-Hodgkin lymphoma) between 1992 and 2008 from Surveillance, Epidemiology, and End Results data. Factors associated with the incidence of second primary malignancies were explored using bivariable and multivariable models, and mortality attributable to first and second primary malignancies was examined. A cohort of 2,116,163 patients was identified, 170,865 of whom (8.1%) developed a second primary malignancy. Survivors of bladder cancer had the highest risk of developing a second cancer. In a multivariable model controlling for age, race, tumor grade, stage of disease, marital status, educational level, and income, a history of non-Hodgkin lymphoma (hazard ratios of 2.70 and 2.88, respectively, for men and women) and bladder cancer (hazard ratios of 1.88 and 1.66, respectively, for men and women) predicted the highest risk of developing a second cancer. For patients with 2 incident cancers, 13% died of their initial cancer, but greater than one-half (55%) died of their second primary malignancy. Lung cancer was the cause of death in 12% of patients with 2 incident cancers. Nearly 1 in 12 patients diagnosed with a common cancer developed a second malignancy, the most common of which was lung cancer. Greater than one-half of patients with 2 incident cancers died of their secondary malignancy. The findings from the current study may inform care strategies among cancer survivors.

    Surgical cytoreduction remains a cornerstone in the management of patients with advanced and recurrent epithelial ovarian cancer. Parenchymal liver metastases determine stage VI disease and are commonly considered a major limit in the achievement of an optimal cytoreduction. The purpose of this manuscript was to discuss the rationale of liver resection and the morbidity related to this procedure in advanced and recurrent ovarian cancer. A search of the National Library of Medicine's MEDLINE/PubMed database until March 2015 was performed using the keywords: "ovarian cancer," "hepatic," "liver," and "metastases." In patients with liver metastases, hepatic resection is associated with a similar prognosis as stage IIIC patients. The length of the disease-free interval between primary diagnosis and occurrence of liver metastases, as well as residual disease after resection, is the most important prognostic factors. In addition, the number of liver lesions, resection margins, and the gynecologic oncology group performance status seem to play also an important role in determining outcome. In properly selected patients, liver resections at the time of cytoreduction increase rates of optimal cytoreduction and improve survival in advanced-stage and recurrent ovarian cancer patients.

    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

    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.

    The purpose of this paper is to evaluate laparoscopic-assisted cytoreduction for primary advanced ovarian cancer: feasibility, morbidity, response to chemotherapy and survival. All patients with presumed stage 3/4 primary ovarian cancer underwent attempted laparoscopic cytoreduction. All patients had CT evidence of omental metastasis and ascites. A five port (5-mm) transperitoneal approach was used. A bilateral salpingo-oophorectomy, supracervical hysterectomy and omentectomy were performed with the PlasmaKinetic (PK) cutting forceps. A laparoscopic 5-mm Argon-Beam Coagulator was used to coagulate tumor in the pelvis, abdominal peritoneum, intestinal mesentery, and diaphragm. Twenty-three cases (92%) were successfully cytoreduced laparoscopically without conversion to laparotomy. Median operative time was 2.3h and median blood loss was 340 cc. All tumors were debulked to less than 2 cm and 36% had no residual disease. Median length of stay was 1 day. Median VAS pain score was 4-discomforting. Six patients (24%) had post-operative complications, none grades 3-4. Median overall survival is 3.5 years. Laparoscopic-assisted cytoreduction for primary advanced ovarian cancer was successful, resulting in minimal morbidity, and acceptable survival. Copyright © 2011 Elsevier Inc. All rights reserved.

    Malignancies are not rare in girl and women during their reproductive years. Over the past three decades, the survival rate for cancer has been improving due to progress in cancer diagnosis and treatment. These patients frequently experience a variety of treatment, and disease-related side effects that diminish their quality of life during and after treatment; among these are loss of fertility and sexual dysfunction. There have been recent advances in the field of fertility preservation, which can allow many of these genital cancer survivors to have children in the future. This topic review discusses available options and specific strategies for fertility preservation in adolescent and young women with malignancies who wish to preserve their ability to become pregnant in the future.

    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

    The Problem of an Adequate Surgical Approach: Frequency of malignant teratomas is, according to the literature, 2%-10%. Examining 194 own cases (1983-1993) it was 1.5%. We found one squamous cell carcinoma (0.5%). Additionally we found 2 immature teratomas (1%). We point out the different biological behaviour of malignant mature teratomas and immature teratomas. We agree with the majority of authors that the method of choice is the intact removal of all teratomas without iatrogen rupture or contamination of the abdominal cavity by contents of the teratoma. This adequate surgical procedure can and should be performed by laparotomy or laparoscopy with endobag. The often practised method of cutting open the cyst during laparoscopy, sucking off the contents or cutting the teratoma into pieces, has been proven to lead to implantation and worsening the prognosis in case of a malignant teratoma. Even the rinsing of the abdominal cavity, usually carried out with this method, could not compensate always for the disadvantage of this "dirty" endoscopical method compared with usual oncological standards. This is pointed out by case reports in the literature and the first analysis of a German survey with early-follow-up of 192 laparoscopically managed ovarian malignancies [11a]. The principle of intact removal of every teratoma should again be kept in mind.

    Malignant melanoma involving the respiratory tract is nearly always metastatic in origin, and primary tumors are extremely rare. Published data on primary pulmonary malignant melanomas are limited. Up to now 40 relevant cases have been reported in the English literature. Herein, we report a case of a 56-year-old female patient who presented with intracranial metastases due to primary pulmonary melanoma. She underwent bronchoscopy and died 5 months after the initial diagnosis despite the administered biochemotherapy and subsequent immunotherapy. To establish the diagnosis of primary pulmonary malignant melanoma, any extrapulmonary origin was excluded by detailed examination and radiographic imaging. Moreover, an extensive review of the literature regarding this rare entity has been performed. PMID:28352484

    Objective. The default window setting on PET/CT workstations is soft tissue. This study investigates whether bone windowing and hybrid FDG PET/CT can help differentiate between malignant and benign primary bone tumors. Materials and methods. A database review included 98 patients with malignant (n=64) or benign primary bone (n=34) tumors. The reference standard was biopsy for malignancies and biopsy or >1 year imaging follow-up of benign tumors. Three radiologists and/or nuclear medicine physicians blinded to diagnosis and other imaging viewed the lesions on CT with bone windows (CT-BW) without and then with PET (PET/CT-BW), and separate PET-only images for malignancy or benignity. Three weeks later the tumors were viewed on CT with soft tissue windows (CT-STW) without and then with PET (PET/CT-STW). Results. Mean sensitivity and specificity for identifying malignancies included: CT-BW: 96%, 90%; CT-STW: 90%, 90%; PET/CT-BW: 95%, 85%, PET/CT-STW: 95%, 86% and PET-only: 96%, 75%, respectively. CT-BW demonstrated higher specificity than PET-only and PET/CT-BW (p=0.0005 and p=0.0103, respectively) and trended toward higher sensitivity than CT-STW (p=0.0759). Malignant primary bone tumors were more avid than benign lesions overall (p<0.0001) but the avidity of benign aggressive lesions (giant cell tumors and Langerhans Cell Histiocytosis) trended higher than the malignancies (p=0.08). Conclusion. Bone windows provided high specificity for distinguishing between malignant and benign primary bone tumors and are recommended when viewing FDG PET/CT. PMID:23983816

    Menopause is a period of women’s life characterized by the cessation of menses in a definitive way. The mean age for menopause is approximately 51 years. Primary ovarian insufficiency (POI) refers to ovarian dysfunction defined as irregular menses and elevated gonadotrophin levels before or at the age of 40 years. The etiology of POI is unknown but several genes have been reported as being of significance. The fragile X mental retardation 1 gene (FMR1) is one of the most important genes associated with POI. The FMR1 gene contains a highly polymorphic CGG repeat in the 5′ untranslated region of exon 1. Four allelic forms have been defined with respect to CGG repeat length and instability during transmission. Normal (5–44 CGG) alleles are usually transmitted from parent to offspring in a stable manner. The full mutation form consists of over 200 repeats, which induces hypermethylation of the FMR1 gene promoter and the subsequent silencing of the gene, associated with Fragile X Syndrome (FXS). Finally, FMR1 intermediate (45–54 CGG) and premutation (55–200 CGG) alleles have been principally associated with two phenotypes, fragile X tremor ataxia syndrome (FXTAS) and fragile X primary ovarian insufficiency (FXPOI).

    Aim. The purpose of the present study was to analyze the predictive and prognostic role of soluble (pro)renin receptor (sPRR) as a biomarker for clinicopathological outcome in patients with primary epithelial ovarian cancer (EOC). As part of the renin-angiotensin system (RAS) whose activity is known to increase in ovarian cancer patients, the relation of sPRR and ovarian cancer should be further investigated. Patients and Methods. In this study 197 patients with primary EOC in our institution from 2000 to 2011 were included. sPRR was determined by enzyme-linked immunosorbent assay (ELISA) in preoperative taken blood sera. Associations with clinicopathological outcome were analyzed and serum levels of sPRR in patients have been compared to those in healthy specimen. Kaplan-Meier and logistic/Cox regression assessed the impact of the markers on progression-free survival (PFS) and overall survival (OS). Results. There have been no correlations proved of sPRR levels with neither clinicopathological factors nor prognostic data. Also the distribution of sPRR in patients and controls was normal. Conclusion. sPRR seems to have no predictive, prognostic, or diagnostic value in EOC. As several factors of the RAS which might indicate cancer events have been shown, sPRR seems not to be affected.

  20. Dose-dense therapy is of benefit in primary treatment of ovarian cancer? In favor.

    Paclitaxel and carboplatin given every 3 weeks is the current standard treatment in first-line chemotherapy regimens for ovarian cancer. The concept of 'dose-dense therapy' is based on the hypothesis that a shortening interval of the doses of cytotoxic agents will be more effective for tumor-cell kill. Recently published phase III trials in breast cancer have shown that dose-dense weekly paclitaxel improves response and survival. The Japanese Gynecologic Oncology Group reported a phase III study comparing the conventional 3-weekly paclitaxel and carboplatin schedule versus dose-dense weekly paclitaxel and 3-weekly carboplatin for advanced epithelial ovarian cancer, fallopian tube cancer or primary peritoneal cancer. The progression-free survival, as the primary endpoint of this study, was significantly prolonged with the dose-dense treatment [28 versus 17.2 months; hazard ratio (HR): 0.71; 95% confidence interval (CI): 0.58-0.88; P=0.0015], as was the overall survival at 3 years (72.1% versus 65.1%; HR 0.75; 95% CI: 0.57-0.98; P=0.03). Dose-dense weekly paclitaxel plus carboplatin represents a new treatment option in women with advanced epithelial ovarian cancer.

    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.

    Cryopreserved ovarian cortical biopsies from 51 patients with breast cancer were examined by histologic and immunohistochemical analysis and showed no sign of metastases. Autotransplantation of ovarian cortex to patients with low-stage breast cancer disease appears safe, but confirmatory studies are required, including xenotransplantation studies.

    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.

    In rare instances, patients may be diagnosed with two different primary malignancies. Though such synchronous malignancies have been documented in sporadic case reports, the overwhelming majority of malignancies involving multiple organs can be attributed to a primary source. Papillary thyroid carcinoma and lung adenocarcinoma are rarely diagnosed within the same year. Our case report presents a patient who was diagnosed with these two malignancies during her same hospital visit. Biopsies results proved that the two malignancies were in fact separate entities and not a consequence of metastasis from a primary source. PMID:26290667

    The rare incidence of primary malignant melanoma of the central nervous system and its ability to mimic other melanocytic tumors on images makes it a diagnostic challenge for the neurosurgeon. A 51-year-old patient, with a tumor located in the right forniceal callosum area. Total surgical excision was performed. Histopathological result was consistent with the diagnosis of primary malignant melanoma of the central nervous system, after ruling out extra cranial and extra spinal melanocytic lesions. The primary malignant melanoma of the central nervous system is extremely rare. There are features in magnetic resonance imaging that increase the diagnostic suspicion; nevertheless there are other tumors with more prevalence that share some of these features through image. Since there is not an established therapeutic standard its prognosis is discouraging. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    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

    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. 2015 BMJ Publishing Group Ltd.

    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.

    We have previously developed a novel class of bi-functional compounds based on a diarylidenyl-piperidone (DAP) backbone conjugated to an N-hydroxypyrroline (-NOH; a nitroxide precursor) group capable of selectively inhibiting STAT3 activation, translocation, and DNA binding activity. HO-4200 and H-4318 are 2 such derivatives capable of inducing apoptosis in ovarian cancer cells through this mechanism and demonstrated efficacy in platinum resistant primary ovarian cancer cell populations and tumor tissues. The improved absorption and cellular uptake of HO-4200 by cancer cells was determined using optical and electron paramagnetic resonance spectrometry. Treatment of ovarian cancer cells with HO-4200 and H-4318 resulted in cleavage of caspase proteins 3, 7, and 9, as well as PARP and inhibition of the pro-survival protein, Bcl-xL, resulting in significantly decreased cell survival and increased apoptosis. HO-4200 and H-4318 significantly inhibit fatty acid synthase (FAS) and pSTAT3 and decreased the expression of STAT3 target proteins: Survivin, c-myc, Bcl-xl, Bcl-2, cyclin D1/D2, and VEGF were suppressed as analyzed using quantitative real time PCR. In addition, HO-4200 and H-4318 significantly inhibited migration/invasion, in primary ovarian cancer cell populations isolated from primary and recurrent ovarian cancer patients. Treatment of freshly collected human ovarian tumor sections with HO-4200 demonstrated significant suppression of pSTAT3 Tyr 705, angiogenesis (VEFG), and markers of proliferation (Ki-67) in ex vivo models. We have shown, for the first time, that the DAP compounds, HO-4200 and H-4318, inhibit cell migration/invasion and induce apoptosis by targeting FAS/STAT3 in human ovarian cancer cells, including primary ovarian cancer cell populations and tumor tissues. Therefore, our results highlight the clinical anti-cancer potential of HO-4200 and H-4318.

    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.

    Our objective was to determine the presence of chromosomal abnormalities in primary cultures of ovarian surface epithelial cells in women of different ages with no history of cancer. Throughout conventional cytogenetic techniques, we analyzed chromosome spreads of cultured ovarian epithelial cells from 10 donors who were 50 or more years old (B) and 16 controls between 20 and 49 years old (A), belonging to the mestizo population in Bogota DC, Colombia. Of the 26 cultures that were analyzed in passage 1, 61.5% had an abnormal chromosome complement (62.5% in A, and 60% in B). Abnormalities included polyploidies, endoduplications and monosomies. Deletions in chromosomes 3 and 11 were found in just one metaphase. None of the samples showed weaknesses or breakpoints. After transforming and applying the exact student's t-test for variance heterogeneity, we found significant differences in the frequency of metaphases, that were higher in A than in B (p=0.05), and in the frequency of polyploidies, which were higher in B than in A (p=0.044). Through the application of the Mann-Whitney test, we determined that the frequency of endoduplications was higher in A than in B (p=0.126), without reaching significant differences. There were no significant differences in the frequency of monosomies. The level of significance was set at p < or = 0.05. Taking into account that polyploidization is a marker of chromosomal instability and that the risk of cancer arising from the ovarian surface epithelium augments substantially after menopause, the increase in the frequency of age-associated polyploidies could be used as a predictor of ovarian cancer in women from an ethnically homogeneous population as the mestizo one in Bogota DC.

    Context: Recently, two patients with primary ovarian insufficiency (POI) delivered healthy babies after in vitro activation (IVA) treatment followed by auto-transplantation of frozen-thawed ovarian tissues. Objective: This study sought to report the first case of live birth after IVA treatment following fresh ovarian tissue grafting in patients with POI, together with monitoring of follicle development and serum hormonal changes. Design: This was a prospective observational cohort study. Setting: We performed IVA treatment in 14 patients with POI with mean age of 29 years, mean duration since last menses of 3.8 years, and average basal FSH level of 94.5 mIU/mL. Interventions: Prior to IVA treatment, all patients received routine hormonal treatments with no follicle development. We removed one ovary from patients with POI and treated them with Akt stimulators. We improved upon early procedures by grafting back fresh tissues using a simplified protocol. Main Outcome Measures: In six of the 14 patients (43%), a total of 15 follicle development waves were detected, and four patients had successful oocyte retrieval to yield six oocytes. For two patients showing no spontaneous follicle growth, human menopausal gonadotropin treatment induced follicle growth at 6–8 months after grafting. After vitro fertilization of oocyte retrieved, four early embryos were derived. Following embryo transfer, one patient became pregnant and delivered a healthy baby boy, with three other embryos under cryopreservation. Conclusion: IVA technology can effectively activate residual follicles in some patients with POI and allow them to conceive their own genetic offspring. IVA may also be useful for treating patients with ovarian dysfunction including aging women and cancer survivors. PMID:27571179

    The present study aimed to investigate the usefulness of the Risk of Ovarian Malignancy Algorithm (ROMA) in the preoperative stratification of patients with ovarian tumors using a novel combination of laboratory tests. The study group (n=619) consisted of 354 premenopausal and 265 postmenopausal patients. The levels of carbohydrate antigen 125 (CA125) and human epididymis protein 4 (HE4) were determined, and ROMA calculations were performed for each pre- and postmenopausal patient. HE4 levels were determined using an electrochemiluminescence immunoassay, while CA125 levels were determined by a chemiluminescence microparticle immunoassay. A contingency table was applied to calculate the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Receiver operating characteristic curves were also constructed, and areas under the curves (AUCs) were compared between the marker determinations and ROMA algorithms. In terms of distinguishing between ovarian cancer and benign disease, the sensitivity of ROMA was 88.3%, specificity was 88.2%, PPV was 75.3% and NPV was 94.9% among all patients. The respective parameters were 71.1, 90.1, 48.2 and 91.1% in premenopausal patients and 93.6, 82.9, 86.6 and 91.6% in postmenopausal patients. The AUC value for the ROMA algorithm was 0.926 for the ovarian cancer vs. benign groups in all patients, 0.813 in premenopausal patients and 0.939 in postmenopausal patients. The respective AUC values were 0.911, 0.879 and 0.934 for CA125; and 0.879, 0.783 and 0.889 for HE4. In this combination, the ROMA algorithm is characterized by an extremely high sensitivity of prediction of ovarian cancer in women with pelvic masses, and may constitute a precise tool with which to support the qualification of patients to appropriate surgical procedures. The ROMA may be useful in diagnosing ovarian endometrial changes in young patients. PMID:27899969

    A network of extracellular signaling factors has previously been shown to act in concert to control the ovarian primordial to primary follicle transition. The current study was designed to investigate the roles of the endogenous bone morphogenetic protein (BMP) inhibitors Gremlin1 (GREM1) and Gremlin2 (GREM2) in primordial follicle transition in the rat ovary. GREM1 and GREM2 treatment were found to reverse the effects of Anti-Müllerian Hormone (AMH) to inhibit follicle transition in a whole ovary culture system. GREM1 reversed the effect of bone morphogenetic protein 4 (BMP4) to stimulate primordial follicle transition. Immunohistochemical studies showed that GREM2, but not GREM1, was present in primordial follicles suggesting GREM2 may regulate primordial follicle transition in vivo. Co-immunoprecipitation studies indicated that GREM2 directly binds to AMH, as well as to BMP4. Transcriptome analyses of ovaries treated with GREM2 or GREM1 yielded negligible numbers of differentially expressed genes, suggesting the immediate effects of GREM2 or GREM1 appear to be at the level of protein-protein interactions, rather than direct actions on the cells. A number of other ovarian growth factors were found to influence the expression of Grem2. Observations suggest that Grem2 is a part of the signaling network of growth factors that regulate the primordial to primary follicle transition. Insights into the regulatory networks affecting the pool of primordial follicles is important to understand the molecular basis for reproductive diseases such as primary ovarian insufficiency (POI).

    2012-01-01

    Background In many tumors including ovarian cancer, cell proliferation and apoptosis are important in pathogenesis and there are many alterations in most of the genes related to the cell cycle. This study was designed to evaluate immunohistochemistry with apoptotic-antiapoptotic proteins (p53, p21, bax, and bcl-2), c-kit, telomerase, and metallothionein as a diagnostic aid in typing of benign, borderline, and malignant serous and mucinous ovarian tumors. Methods Total of 68 ovarian tumors, 25 benign [13 (19.1%) serous and12 (17.6%) mucinous], 16 borderline [9 (13.2%) serous and 7(10.3%) mucinous], and 27 malignant ovarian tumors [24 (35.3%) serous and 3 (4.4%) mucinous tumors] were included in the study. Immunohistochemical expression of p53, p21, bax, bcl–2, telomerase, c-kit, and metallothionein were evaluated. Results When all 68 cases were evaluated as benign, borderline, and malignant ovarian tumors without considering histopathological subtypes, the p53, p21, bax and metallothionein showed significantly higher staining scores in the borderline and malignant ones (p < 0.05). After evaluation of all 68 cases, the serous tumors showed significantly higher staining scores of p53, p21, c-kit, and metallothionein compared to the mucinous ones (p < 0.05). For differentiation of benign and borderline and malignant tumors combined, p53 was not used because all benign tumors has no staining, and p21, bax, and metallothionein was determined the significant predictors for borderline and malignant tumors combined (p < 0.05). For differentiation of borderline and malignant tumors, only p53 was determined the significant predictor for malignant tumors (p < 0.05). Conclusions In conclusion, p53, p21, bax, c-kit, and metallothionein may be helpful for the typing of ovarian tumors as benign, borderline and malignant or serous and mucinous. p53, p21, bax, c-kit, and metallothionein may have different roles in the pathogenesis of ovarian tumor types. p53 and

    Integrins, a family of heterodimeric receptors for extracellular matrix, are promising therapeutic targets for ovarian cancer, particularly high-grade serous-type (HGSOC), as they drive tumor cell attachment, migration, proliferation and survival by activating focal adhesion kinase (FAK)-dependent signaling. Owing to the potential off-target effects of FAK inhibitors, disruption of the integrin signaling axis remains to be a challenge. Here, we tackled this barrier by screening for inhibitors being functionally cooperative with small-molecule VS-6063, a phase II FAK inhibitor. From this screening, JQ1, a potent inhibitor of Myc oncogenic network, emerged as the most robust collaborator. Treatment with a combination of VS-6063 and JQ1 synergistically caused an arrest of tumor cells at the G2/M phase and a decrease in the XIAP-linked cell survival. Our subsequent mechanistic analyses indicate that this functional cooperation was strongly associated with the concomitant disruption of activation or expression of FAK and c-Myc as well as their downstream signaling through the PI3K/Akt pathway. In line with these observations, we detected a strong co-amplification or upregulation at genomic or protein level for FAK and c-Myc in a large portion of primary tumors in the TCGA or a local HGSOC patient cohort. Taken together, our results suggest that the integrin–FAK signaling axis and c-Myc synergistically drive cell proliferation, survival and oncogenic potential in HGSOC. As such, our study provides key genetic, functional and signaling bases for the small-molecule-based co-targeting of these two distinct oncogenic drivers as a new line of targeted therapy against human ovarian cancer.

    Ovarian cancer is the seventh leading cause of cancer death worldwide. This is mainly due to late diagnosis and high rate of relapse and resistance following chemotherapy. In the present study, we describe simple and cost-effective method to establish primary culture from ascitic fluid and solid tumor obtained from epithelial ovarian carcinoma patient, which may provide a better tool for in vitro testing of drug sensitivity and designing individualized treatment protocol. Complete Dulbecco modified Eagle medium (DMEM) was prepared by supplementing DMEM with 10% fetal bovine serum and antibiotics (ciprofloxacin and amphotericin B). Establishment of primary culture of ovarian cancer cells from ascites fluid and solid tumor was done by using complete DMEM media. Primary cultures of ovarian cancer cells were established from ascitic fluid and solid tumor tissue. Of the 7 ascitic fluid samples, we were able to establish 5 primary cultures of ovarian cancer cells. All the 7 samples were diagnosed as serous papillary adenocarcinoma. Some fibroblasts were also attached to culture flask on day 4; they were removed by exposing them to trypsin for a brief period. On day 7, grape-like clusters were visualized under inverted microscope. The cells became confluent on the 10th and 11th day and showed cobblestone appearance, which is a hallmark of ovarian cancer cells. Senescent irregularly shaped cells that have ceased dividing were seen after 8 to 10 passages. This study highlights the fact that establishing primary cultures from ascitic fluid or solid tumor tissue may help us to understand the molecular profile of the cancer cells, which allow us to select the best chemotherapeutic agent for ovarian cancer patients and thus take a step toward patient-tailored therapy so that patients are not exposed to drugs to which they are not likely to respond.

    Primary hypothyroidism may be associated with ovarian enlargement and/ or cyst formation. We evaluated the effect of thyroid hormone replacement therapy on hormonal changes, ovarian volume and sonographic appearance. Open, prospective study of women admitted to university gynecology clinic. The study included 26 patients with untreated hypothyroidism who had polycystic (n=10) or normal-appearing (n=16) ovaries and 20 euthyroidic controls. Basal serum total testosterone, free testosterone, androstenedione, dehydroepiandosterone-sulfate, prolactin, estradiol, luteinizing hormone, follicle-stimulating hormone, free T3, free T4 and thyroid-stimulating horone, together with ovarian volumes, were determined and repeated after euthyroidism was achieved. Ovarian volumes of patients with hypothyroidism were significantly greater compared with controls, and their magnitudes diminished significantly during thyroid hormone replacement therapy. Hypothyroidic patients with polycystic ovaries had significantly higher serum free testosterone and dehydroepiandosterone-sulfate, but lower androstenodione levels compared with those who had normal-appearing ovaries. Serum total testosterone concentrations were significantly higher in hypothyroidic patients without polycystic ovaries, and thyroid hormone replacement therapy achieved a significant reduction in total as well as free testosterone. Severe longstanding hypothyroidism leads to increased ovarian volume and/or cyst formation. A decrease in ovarian volume, resolution of ovarian cysts and reversal of the polycystic ovary syndrome-like appearance, together with improvement in serum hormone levels, occurred after euthyroidism was achieved.

    Primary actinomycosis occurring in urachal remnants is rarely documented in literature and may mislead the clinicians to diagnose urachal carcinoma. A 50-year-old man came with complaints of lower abdominal pain, dysuria, and dribbling of urine for 2 months. A vague mass of 7 cm was palpable in the suprapubic region. Imaging of the abdomen revealed an irregular mass seen superior to fundus of the urinary bladder appearing adherent to mesentery and bowel loops, suggesting an urachal remnant associated lesion with infiltration. Provisional diagnosis of urachal carcinoma was considered. Excision of the mass with partial cystectomy and resection of involved ileal segments were done. Microscopic examination revealed actinomycotic colonies surrounded by microabscesses and dense inflammatory fibrotic lesion. Small intestinal segments showed a similar lesion in the serosa.

    Aurora A kinase (AAK), a key mitotic regulator, is implicated in the pathogenesis of several tumors, including ovarian cancer. This single-arm phase II study assessed single-agent efficacy and safety of the investigational AAK inhibitor MLN8237 (alisertib), in patients with platinum-refractory or -resistant epithelial ovarian, fallopian tube, or primary peritoneal carcinoma. Adult women with malignant, platinum-treated disease received MLN8237 50mg orally twice daily for 7 days plus 14 days' rest (21-day cycles). The primary endpoint was combined objective tumor response rate per Response Evaluation Criteria in Solid Tumors (RECIST) and/or CA-125 criteria. Secondary endpoints included response duration, clinical benefit rate, progression-free survival (PFS), time-to-progression (TTP), and safety. Thirty-one patients with epithelial ovarian (n=25), primary peritoneal (n=5), and fallopian tube carcinomas (n=1) were enrolled. Responses of 6.9-11.1 month duration were observed in 3 (10%) patients with platinum-resistant ovarian cancer. Sixteen (52%) patients achieved stable disease with a mean duration of response of 2.86 months and which was durable for ≥3 months in 6 (19%). Median PFS and TTP were 1.9 months. Most common drug-related grade≥3 adverse events were neutropenia (42%), leukopenia (23%), stomatitis, and thrombocytopenia (each 19%); 6% reported febrile neutropenia. These data suggest that MLN8237 has modest single-agent antitumor activity and may produce responses and durable disease control in some patients with platinum-resistant ovarian cancer. MLN8237 is currently undergoing evaluation in a phase I/II trial with paclitaxel in recurrent ovarian cancer. Copyright © 2012. Published by Elsevier Inc.

    Malignant fibrous histiocytomas (MFH) are the most commonly seen soft tissue sarcomas in adults. It is rarely seen in some visceral organs. Kidneys are the parenchymal organs in which MFHs are most frequently seen. More than 50 cases of primary renal MFH have been reported. Among these cases, only 1 was reported as primary giant cell subtype in association with urolithiasis. This case report is the second such case with the these characteristics. PMID:24678364

    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.

    Cancers accumulate mutations over time, each of which brings the potential for recognition by the immune system. We evaluated T-cell recognition of the tumor mutanome in patients with ovarian cancer undergoing standard treatment. Tumor-associated T cells from 3 patients with ovarian cancer were assessed by ELISPOT for recognition of nonsynonymous mutations identified by whole exome sequencing of autologous tumor. The relative levels of mutations and responding T cells were monitored in serial tumor samples collected at primary surgery and first and second recurrence. The vast majority of mutations (78/79) were not recognized by tumor-associated T cells; however, a highly specific CD8(+) T-cell response to the mutation hydroxysteroid dehydrogenase-like protein 1 (HSDL1)(L25V) was detected in one patient. In the primary tumor, the HSDL1(L25V) mutation had low prevalence and expression, and a corresponding T-cell response was undetectable. At first recurrence, there was a striking increase in the abundance of the mutation and corresponding MHC class I epitope, and this was accompanied by the emergence of the HSDL1(L25V)-specific CD8(+) T-cell response. At second recurrence, the HSDL1(L25V) mutation and epitope continued to be expressed; however, the corresponding T-cell response was no longer detectable. The immune system can respond to the evolving ovarian cancer genome. However, the T-cell response detected here was rare, was transient, and ultimately failed to prevent disease progression. These findings reveal the limitations of spontaneous tumor immunity in the setting of standard treatments and suggest a high degree of ignorance of tumor mutations that could potentially be reversed by immunotherapy. ©2013 AACR

    Determine the effects of factors secreted by normal human ovarian stroma on the proliferation of benign and malignant ovarian epithelia, in vitro. Primary cultures of normal human ovarian surface epithelium (HOSE), human ovarian stromal tissue (HOST), and epithelial ovarian carcinomas (CSOC) were established from surgical specimens and characterized immunohistochemically using anti-cytokeratin, vimentin, and Factor VIII antibodies. Stroma-conditioned media (SCM) were collected over 3 days from confluent HOST cultures. The SCM were dialyzed, lyophilized, resuspended, and added to HOSE, CSOC, SKOV-3, and Caov-3 ovarian cancer cell cultures and growth inhibitory effects were assayed by MTS and [3H]thymidine uptake. SCM inhibited the growth and DNA synthesis of normal HOSE cells and cancer cells by 79-99% in > 10-cell lines studied to date. The inhibitory effect was rapid in onset with 31-82% reduction in DNA synthesis at 1 hr and approximately 50% return of activity by 23 hr following a 1-hr SCM pulse treatment. The SCM inhibitory activity was not abolished by boiling or by absorption with heparin-agarose. Size exclusion filtration places the molecular weight of the inhibitory substance between 1 and 3 kDa. Neither trypsin nor proteinase K treatments altered the inhibitory activity of SCM, while a Bligh-Dyer organic extraction placed the activity in the aqueous phase. A heat-stable, non-heparin-binding, low-molecular-weight, water-soluble substance secreted by normal ovarian stroma significantly inhibits HOSE and ovarian cancer cell proliferation. Derangements in normal ovarian stroma-epithelial interactions may contribute to growth dysregulation of the surface epithelia and result in ovarian carcinogenesis.

    Indications and results of salvage surgery in mediastinal tumors are still unclear. This study analyzes a single-center experience to assess its mortality, morbidity, and long-term results. Mediastinal salvage surgery (MSS) was defined as surgical resection of persistent or recurrent primary mediastinal tumors after previous local treatments with curative intent or exclusive chemotherapy in case of bulky tumors. Clinical data of patients undergoing MSS between 1998 and 2005 were analyzed. Overall and disease-specific long-term survival was calculated. Twenty-one patients (15 men and 6 women, mean age 41 years) underwent MSS. Eleven patients suffered from thymic tumors (eight thymomas, three thymic carcinoma) whereas 10 patients suffered from nonthymic tumors (one lung adenocarcinoma + thymoma, two mediastinal monophasic sinovial sarcoma, one mediastinal neuroendocrine tumor, one mediastinal teratoblastoma, one mediastinal disgerminoma, one Hodgkin's lymphoma, one mediastinal atypic carcinoid, two medullary thyroid carcinoma). MSS required extended vascular resection in 10 cases and cardiopulmonary bypass in one case. Median operation time was 215 minutes (range 140-720). One postoperative death and four major complications were recorded (overall mortality 4.7%, morbidity 19.0%). With a median follow-up of 30.6 months, overall 1-, 3-, and 5-year Kaplan-Meier survival was 89.7, 71.2, and 56.6%, respectively. Thymic neoplasms had a better prognosis (1-, 3-, and 5-year survival was 100, 87.5, 87.5%, respectively) when compared with others (1-, 3-, and 5-year survival was 77.8, 53.3, 26.7%, respectively--logrank p = 0.0128). MSS can offer a chance of curative treatment in selected patients with an acceptable morbidity and mortality. Thymic tumors obtain the best results in term of long-term survival.

    Introduction Colorectal cancer in patients younger than 50 years of age is increasing steadily in the UK with limited guidelines available indicating need for secondary care referral. The aims of this study were to report the cancer incidence in those aged under 50 years referred to secondary care with suspected colorectal malignancy and also to analyse the quality of those referrals. Methods A total of 197 primary care referrals made between 2008 and 2014 to a UK district general hospital for suspected colorectal malignancy were analysed. All confirmed cancers were further evaluated regarding presenting symptoms, tumour characteristics and clinical outcomes. Each referral was given a referral performance score (out of 9) dependant on relevant information documented. Results The overall malignancy rate was 9.1% (11 male and 7 female patients). The median age in this cohort was 41.5 years (interquartile range [IQR]: 37–49 years). Abdominal pain was the only presenting symptom to differ significantly when comparing malignant with non-malignant patients (44.4% vs 21.8% respectively, p=0.042). The median time period between referral date and colorectal specialist consultation was 11 days (IQR: 7–13 days) and the median referral performance score was 5 (range: 3–9). Conclusions Malignancy is prevalent in patients under 50 years of age who are referred to secondary care for suspected colorectal cancer. Those referred with abdominal pain in the presence of other high risk lower gastrointestinal symptoms are at significant risk of having a malignancy. Major deficiencies are apparent in urgent primary care referrals, highlighting the need for further national guidance to aid early diagnosis of colorectal cancer in the young. PMID:27023637

    We report a case of laparoscopic management of a primary malignant melanoma of the left adrenal gland. A 42-year-old male presented a 55 x 60-mm round, inhomogeneous, noninvasive mass of the left adrenal gland. Hormone-activity values were within normal range. The mass was removed laparoscopically en bloc along with the left adrenal gland, and its histopathologic evaluation was consistent with the features of a malignant melanocytic tumor. Postoperatively, the patient presented no signs of fever or remarkable blood loss and was discharged on the third day in good clinical condition. He is free of disease 1 year later.

    Ovarian growth (vitellogenesis) in most lower vertebrates is mediated by estradiol-17beta (E2) secreted by the follicles in response to follicle-stimulating hormone (Fsh), whereas oocyte maturation and ovulation are mediated by progestins, such as 17alpha,20beta-dihydroxypregn-4-en-3-one (17,20beta-P), produced in response to luteinizing hormone (Lh). In teleosts, follicular synthesis of 17,20beta-P at the time of maturation is due primarily to up-regulation of the enzymes P450c17-II (Cyp17a2) and 20beta-hydroxysteroid dehydrogenase (Cbr1). Here, we show that follicular cells associated with primary growth (previtellogenic) oocytes of the gilthead seabream also express cyp17a2 and cbr1, in addition to P450c17-I (cyp17a1) and aromatase (cyp19a1), enzymes required for E2 synthesis. Ovaries containing only oogonia and early primary ovarian follicles had a 60-fold higher concentration of 17,20beta-P than ovaries in the succeeding stages and had a higher expression of cbr1 and Fsh receptor (fshra). Stimulation of explants of primary follicles in vitro with recombinant piscine Fsh (rFsh), which specifically activates the seabream Fshra, promoted a rapid accumulation of 17,20beta-P, and synthesis was sustained by an external supply of 17alpha-hydroxyprogesterone. In the presence of Cbr1 inhibitors, rFsh-mediated 17,20beta-P production was reduced, with a concomitant increase in testosterone and E2 synthesis. In primary explants, rFsh up-regulated cyp17a2 and cbr1 transcription and simultaneously down-regulated cyp17a1 and cyp19a1 steady-state mRNA levels within 24 h. In contrast, in explants containing vitellogenic follicles, rFsh had no effect on cyp17a2 and cbr1 expression, but increased that of cyp17a1 and cyp19a1. These data suggest a functional Fshra-activated Cyp17a2/Cbr1 steroidogenic pathway in gilthead seabream primary ovarian follicles triggering the production of 17,20beta-P.

    BACKGROUND-MATERIALS: This study aimed to investigate biomagnetic activity in benign and malignant ovarian diseases using the biomagnetometer SQUID. Magnetic recordings were obtained from 40 patients with palpable ovarian lesions. 19 of these were invasive carcinomas, and 21 were benign ovarian lesions. We used a one channel biomagnetometer SQUID (superconducting quantum interference device), in order to measure the magnetic field from benign and malignant ovarian diseases. Interestingly, the ovarian lesion waveforms and the corresponding spectral densities were of high amplitude in most (96%) malignant ovarian lesions, and of low amplitude in most (95%) benign ovarian diseases. These findings were of statistical significance (students t-test p < 0.005). It is suggested that biomagnetic measurement of benign and malignant ovarian diseases, which is an entirely new application of SQUID technology, is a promising procedure for assessing ovarian tumors.

    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

    2012-10-01

    Malignant ameloblastoma is a rare tumor of odontogenic origin with a metastatic focus. Distant metastatic disease is found most commonly in the lungs. A review of the literature shows that most cases of malignant ameloblastoma involve a disease-free period from primary tumor extirpation to the discovery of metastasis. This report describes the case of a 56-year-old man presenting with ameloblastoma of the maxilla and a solitary pulmonary metastasis concurrently. This represents a rare case in which there is a simultaneous diagnosis of primary ameloblastoma and a metastatic lesion. Appropriate workup for ameloblastoma includes surveillance for metastatic disease. Surgical resection of primary and distant disease is recommended. Chemotherapy and radiation may play a role in palliation when resection of metastatic disease is not feasible. Copyright © 2012 American Association of Oral and Maxillofacial Surgeons.

    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.

    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.

    We report a case of primary malignant melanoma of cervix which is a rare malignancy with only around 60 cases being reported. This patient presented with bleeding per vaginum. A large exophytic growth from cervix with black discolouration was seen. International Federation of Gynaecology and Obsterics (FIGO) staging was stage IIa. Histoimmunocytology confirmed the diagnosis of malignant melanoma of cervix. S-100 and HMB-45 are reliable markers for cervical melanomas. We attempted Wertheim's hysterectomy; but, due to extensive disease, paravescical and pararectal fossae could not be dissected and we had to perform type I hysterectomy. The patient was started on adjuvant chemotherapy with dacarbazine. Despite counselling, she refused a complete course of chemotherapy and died after 6 months. Radical surgery, chemotherapy and immunotherapy are the therapeutic modalities used. In bulky disease, neoadjuvant chemotherapy should be considered to reduce the tumour bulk and facilitate required surgery. Prognosis is poor and unpredictable. PMID:23737592

    Recurrence following primary platinum-based chemotherapy remains a challenge in the treatment of patients with advanced-stage epithelial ovarian cancer. This study examines whether a chemoresponse assay can identify patients who are platinum-resistant prior to treatment. Women (n = 276) with International Federation of Gynecology and Obstetrics stage III-IV ovarian, fallopian, and peritoneal cancer were enrolled in an observational study, and the responsiveness of their tumors was evaluated using a chemoresponse assay. All patients were treated with a platinum/taxane regimen following cytoreductive surgery. Assay responses to carboplatin or paclitaxel were classified as sensitive, intermediate sensitive (IS), or resistant. Association of assay response with progression-free survival (PFS) was analyzed using the Kaplan-Meier method and a Cox regression model. Patients whose tumors were resistant to carboplatin were at increased risk of disease progression compared to those with nonresistant (sensitive + IS) tumors (median PFS: 11.8 vs 16.6 months, respectively, P < .001), and the association was confirmed after adjusting for other clinical factors (hazard ratio, 1.71; 95% confidence interval, 1.12-2.62; P = .013). Association of assay response to paclitaxel with PFS trended in multivariate analysis (hazard ratio, 1.28; 95% confidence interval, 0.84-1.95; P = .245). For tumors resistant to carboplatin, 59% were sensitive or IS to at least 1 other commonly used agent, demonstrating the ability of the assay to inform treatment decisions beyond the standard platinum/taxane regimen. Assay resistance to carboplatin is strongly associated with shortened PFS among advanced-stage epithelial ovarian cancer patients treated with carboplatin + paclitaxel therapy, supporting use of this assay to identify patients likely to experience early recurrence on standard platinum-based therapy.

    Ovarian cancer spheroids constitute a metastatic niche for transcoelomic spread that also engenders drug resistance. Spheroid-forming cells express active STAT3 signaling and display stem cell-like properties that may contribute to ovarian tumor progression. In this study, we show that STAT3 is hyperactivated in ovarian cancer spheroids and that STAT3 disruption in this setting is sufficient to relieve chemoresistance. In an NSG murine model of human ovarian cancer, STAT3 signaling regulated spheroid formation and self-renewal properties, whereas STAT3 attenuation reduced tumorigenicity. Mechanistic investigations revealed that Wnt signaling was required for STAT3-mediated spheroid formation. Notably, the Wnt antagonist DKK1 was the most strikingly upregulated gene in response to STAT3 attenuation in ovarian cancer cells. STAT3 signaling maintained stemness and interconnected Wnt/β-catenin signaling via the miR-92a/DKK1-regulatory pathways. Targeting STAT3 in combination with paclitaxel synergistically reduced peritoneal seeding and prolonged survival in a murine model of intraperitoneal ovarian cancer. Overall, our findings define a STAT3-miR-92a-DKK1 pathway in the generation of cancer stem-like cells in ovarian tumors, with potential therapeutic applications in blocking their progression.

    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.

    Malignant lymphoma commonly occurs in adults, with a peak incidence between the seventh and ninth decades of life. Although malignant lymphoma usually occurs in the lymph nodes, it rarely occurs primarily in the bone. We herein describe an extremely rare case of primary malignant lymphoma of the talus in a 74-year-old man. Although plain radiographs showed no abnormality, gadolinium-enhanced magnetic resonance imaging (MRI) revealed a well-circumscribed intra- and extraosseous tumor of the talus. (18)F-fluorodeoxyglucose (FDG) positron emission tomography/MRI revealed a marked increase of FDG uptake in the right ankle and the right inguinal lymph nodes. As the tumor was diagnosed as diffuse large B-cell lymphoma by core needle biopsy, combination therapy with chemo- and radiotherapy was initiated. The patient achieved complete remission, with no sign of recurrence at 8 months after initial chemoradiotherapy. Since primary malignant lymphoma of the bone is chemo- and radiosensitive and has a good prognosis, accurate staging by radiological investigation as well as correct pathological diagnosis by biopsy are required for optimal treatment.

    This study assessed pentavalent {sup 99m}Tc-DMSA uptake in primary brain tumors and evaluated the relationship between retention and histologic malignancy. SPECT images of the brain were obtained at 30 min and 3 hr after intravenous administration of approximately 555 MBq {sup 99m}Tc(V)-DMSA in patients with brain tumors. Sixty studies were performed in 57 patients and 63 lesions were demonstrated: 11 glioblastomas, 13 anaplastic astrocytomas (Grade 3), 11 astrocytomas (Grade 2), 18 meningiomas and 10 schwannomas. Uptake ratios, retention ratio and retention index were calculated and compared with tumor histology and malignancy grade. Approximately 95% of both benign and malignant primary brain tumors were demonstrated by {sup 99m}Tc(V)-DMSA SPECT images. False negative was noted in three cases. The early uptake ratios were closely related to the tumor vascularity but had no statistically significant difference in the tumor vascularity but had no statistically significant difference in the tumor histology or histologic malignancy. 16 refs., 6 figs., 2 tabs.

    Fragile X premutation carriers have 55-200 CGG repeats in the 5' untranslated region of the FMR1 gene. Women with this premutation face many physical and emotional challenges in their life. Approximately 20% of these women will develop fragile X-associated primary ovarian insufficiency (FXPOI). In addition, they suffer from increased rates of menstrual dysfunction, diminished ovarian reserve, reduction in age of menopause, infertility, dizygotic twinning, and risk of having an offspring with a premutation or full mutation. Consequent chronic hypoestrogenism may result in impaired bone health and increased cardiovascular risk. Neuropsychiatric issues include risk of developing fragile X-associated tremor/ataxia syndrome, neuropathy, musculoskeletal problems, increased prevalence of anxiety, depression, and sleep disturbances independent of the stress of raising an offspring with fragile X syndrome and higher risk of postpartum depression. Some studies have reported a higher prevalence of thyroid abnormalities and hypertension in these women. Reproductive health providers play an important role in the health supervision of women with fragile X premutation. Awareness of these risks and correlation of the various manifestations could help in early diagnosis and coordination of care and services for these women and their families. This paper reviews current evidence regarding the possible conditions that may present in women with premutation-sized repeats beyond FXPOI.

    Bone morphogenetic protein (BMP)15 is an oocyte-specific growth factor, which, together with growth differentiation factor (GDF) 9, regulates folliculogenesis and ovulation rate. Multiple mutations in BMP15 have been identified in women with primary ovarian insufficiency (POI), supporting a pathogenic role; however, the underlying biological mechanism of many of these mutants remains unresolved. To determine how mutations associated with ovarian dysfunction alter the biological activity of human BMP15. The effects of 10 mutations in BMP15 on protein production, activation of granulosa cells, and synergy with GDF9 were assessed. Sequencing of 35 patients with POI identified both an unrecognized BMP15 variant (c.986G>A, R329H) and a variant (c.581T>C, F194S) previously associated with the condition. Assessing expression and activity of these and 8 other BMP15 mutants identified: (1) multiple variants, including L148P, F194S, and Y235C, with reduced mature protein production; (2) three variants (R138H, A180T, and R329H) with ∼fourfold lower activity than wild-type BMP15; and (3) 3 variants (R68W, F194S, and N196K) with a significantly reduced ability to synergize with GDF9. Mutations in BMP15 associated with POI reduce mature protein production, activity, or synergy with GDF9. The latter effect is perhaps most interesting given that interactions with GDF9 most likely underlie the physiology of BMP15 in the human ovary.

    We report the first case of primary intraosseous smooth muscle tumor of uncertain malignant potential (STUMP) which is analogous to borderline malignant uterine smooth muscle tumors so designated. The tumor presented in the femur of an otherwise healthy 30-year-old woman. Over a 3-year period, the patient underwent 11 biopsies or resections and 2 cytologic procedures. Multiple pathologists reviewed the histologic material including musculoskeletal pathologists but could not reach a definitive diagnosis. However, metastases eventually developed and were rapidly progressive and responsive to gemcitabine and docetaxel. Molecular characterization and ultrastructural analysis was consistent with smooth muscle origin, and amplification of unmutated chromosome 12p and 12q segments appears to be the major genomic driver of this tumor. Primary intraosseous STUMP is thought to be genetically related to leiomyosarcoma of bone, but likely representing an earlier stage of carcinogenesis. Wide excision and aggressive follow-up is warranted for this potentially life-threatening neoplasm. PMID:27994831

    Cadherin-11 (CDH11, OB-cadherin) is a mesenchymal cadherin found to be upregulated in various types of tumors and implicated in tumor progression and metastasis. In order to determine the role of CDH11 expression in ovarian tumors, we performed a combined reverse transcription quantitative polymerase chain reaction (RT-qPCR), western blot analysis and immunohistochemical study on a large cohort of benign, borderline and invasive ovarian tumors. The RT-qPCR and western blot analysis demonstrated that the CDH11 expression was high in benign cystadenomas and decreased with increasing malignancy. This may be explained by the different tumor-stroma ratios, since immunohistochemistry revealed strong staining of stromal cells, particularly vascular smooth muscle cells and endothelial cells, but only weak cytoplasmic or nuclear immunoreactivity of cancer cells. Within the group of invasive carcinomas, high CDH11 protein expression, as detected by western blot analysis, was found to be significantly correlated with advanced stage and nodal involvement. However, the recurrence-free and overall survival analyses did not reveal any prognostic or predictive significance. In conclusion, in contrast to other tumor types, CDH11 does not play an important role in ovarian cancer progression. PMID:26623052

    Primary malignant melanoma (MM) of the uterine cervix is an extremely rare neoplasm, with about 78 cases described in the literature. Since traces of melanocytes in normal cervical epithelium were found in 3.5% of cases primary origin of melanoma at this site cannot be ruled out. It occurs mainly in the sixth decade of life, and it is five time less common than primary vaginal or vulvar MM. Clinical history usually includes abnormal genital bleeding; and physical examination frequently reveals a pigmented, exophytic cervical mass. Diagnosis is confirmed by immuno-histochemical methods and by exclusion of any other primary site of melanoma. Treatment of this condition is not yet standardized, and the overall prognosis is very poor. Diagnostic approaches and therapeutic procedures on primary MM of the uterine cervix are discussed following a review of the literature encompassing more than one century.

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

    Conservative treatment of metastatic germ-cell tumor of the ovary does not exclude the possibility of pregnancy in the future. Serum beta-human chorionic gonadotropin (beta-hCG) serves as pregnancy test, and has also been proven to be a useful marker for ovarian germ-cell tumors. This paper is a case report of a 19-year-old patient who was admitted to a district hospital in emergency due to pelvic pain, amenorrhoea, and free fluid in the pelvis. Laboratory tests demonstrated slight increase in beta-hCG serum concentration and transvaginal ultrasound (TVUS) showed no evidence of gestational sac in the uterus. At the age of 14, the patient was diagnosed with malignant germ-cell tumor of the left ovary in FIGO Stage IV and was treated with four courses of chemotherapy according to TGM-95 protocol with etoposide, ifosfamide, and cisplatin, followed by conservative surgery and adjuvant two courses of cytostatics. The initial diagnosis was recurrence of ovarian malignancy and the patient was referred to an oncology center. Wait-and-see approach and repeated ultrasound examination confirmed a normal intrauterine pregnancy which concluded with the delivery of a healthy newborn through cesarean section.

    Immunodeficiency is associated with higher cancer incidence. However, it is unknown whether there is a link between immunodeficiency and development of multiple primary malignancies. In the present study we analyse this link focusing on kidney-transplanted patients, as they are at higher risk of developing cancer due to the chronic assumption of immunosuppressants. We followed up 1200 patients who underwent kidney transplantation between 1980 and 2012. A total of 77/1200 kidney-transplanted patients developed cancer and 24 of them developed multiple cancers. Most multiple cancers were synchronous with a nonsignificant association between cancer and rejection episodes. In the general cancer population, one-ninth of patients are at higher risk of developing a second tumor over a lifetime; hence it would be reasonable to conclude that, from a merely theoretical and statistical viewpoint, long-term transplanted patients potentially have a higher risk of developing MPMs. However, data did not confirm this assumption, probably because these patients die before a second primary malignancy appears. Despite many observations on the increased incidence of different tumor types in immunodeficient patients and despite immunosuppression certainly being a predisposing factor for the multicancer syndrome, data so far are not robust enough to justify a correlation between immunodeficiency and multiple primary malignancies in transplanted patients.

    A 16-year-old girl presented with primary amenorrhea and excess hair growth on her body and face for the last three years, along with pain and a mass in her lower abdomen for last one year. Examination revealed hirsutism and other virilizing features, with an irregular mass in the lower abdomen corresponding to 16 weeks'gestation. Serum testosterone was 320 ng / dl and ultrasonogram of the pelvis revealed a solid mass of 5 × 4 cm in the left adnexa. Suspecting it to be a virilizing tumor of the left ovary, the patient was subjected to staging laparotomy, which revealed stage 1a ovarian involvement amenable to surgical resection alone. Histopathological examination confirmed the diagnosis of granulosa cell tumor of the ovary. Postoperatively the serum testosterone returned to 40 ng / dl and her menstrual cycle started after two months of surgery.

    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.

    Objective To examine the use, as well as postoperative and long-term oncologic outcomes of diverting loop ileostomy (DI) during primary debulking surgery (PDS) for ovarian cancer. Methods Patients with stage II–IV ovarian, fallopian tube, or primary peritoneal carcinoma who underwent colon resection during PDS from 1/2005–1/2014 were identified. Demographic and clinical data were analyzed. Results Of 331 patients, 320 (97%) had stage III/IV disease and 278 (84%) had disease of high-grade serous histology. Forty-four (13%) underwent a DI. There were no significant differences in age, comorbidity index, smoking status, serum albumin, or attending surgeon between the DI and non-DI groups. Operative time (OR=1.21; 95% CI, 1.03–1.42; p=.02) and length of rectosigmoid resection (OR=1.04; 95% CI, 1.01–1.08; p=.02) were predictors of DI on multivariable analysis. The overall anastomotic leak rate was 6%. A comparison of groups (DI vs non-DI) showed no significant differences in major complications (30% vs 23%; p=.41), anastomotic leak rate (5% vs 7%; p=.60), hospital length of stay (10 vs 9 days; p=.25), readmission rate (23% vs 17%; p=.33), or interval to postoperative chemotherapy (41 vs 40 days; p=.20), respectively. Ileostomy reversal was successful in 89% of patients. Median follow-up was 52.6 months. There were no differences in median progression-free (17.9 vs 18.6 months; p=.88) and overall survival (48.7 vs 63.8 months; p=.25) between the groups. Conclusions In patients undergoing PDS, those with longer operative time and greater length of rectosigmoid resection more commonly underwent DI. DI does not appear to compromise postoperative outcomes or long-term survival. PMID:27261325

    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 use of neoadjuvant chemotherapy (NAC) in the treatment of advanced ovarian cancer has increased in recent years. There is uncertainty about NAC's effectiveness and no study of its cost-effectiveness compared with that of standard primary debulking surgery (PDS). To seek answers to three important questions: 1) What is the lifetime cost of treating elderly patients with advanced ovarian cancer, based on the primary treatment received? 2) Are the extra costs expended by the NAC group worth any extra survival advantage? 3) Would NAC potentially benefit a particular subgroup and serve as a cost-effective first-line treatment approach? A cohort of elderly women (≥65 years) with stage III/IV ovarian cancer was identified from the Surveillance, Epidemiology and End Results-Medicare linked database from January 1, 2000, to December 31, 2009. Cost analysis was conducted from a payer perspective, and direct medical costs incurred by Medicare were integrated for each patient. Cumulative treatment costs were estimated with a phase-of-care approach, and effectiveness was measured as years of survival. Incremental cost-effectiveness ratio (ICER) and propensity-score-adjusted net monetary benefit regression was used to estimate the cost-effectiveness of NAC per life-year gained. Analyses were further stratified by risk group categorization on the basis of tumor stage, patient age, and comorbidity score. Average lifetime cost for treatment with NAC was $17,417 more than with PDS. With only 0.1 incremental life-year gained, the ICER estimate was $174,173. Stratification, however, helped to delineate the treatment effect. Patients in the high-risk subgroup incurred $34,390 and 0.8 life-years more than did patients in the PDS subgroup, with a corresponding ICER of $42,987. In the non-high-risk subgroup, NAC use was dominated by PDS (more costly, less effective). Administering NAC before surgery to patients in the high-risk subgroup was cost-effective at "normal" levels of

    Primary malignant melanoma of the central nervous system is an uncommon localization, first reported by Hirsberg in 1906. Since then, to our knowledge, only 39 cases have been reported in the literature. We present a case of primary intradural extra-medullary melanoma which developed in a 51-Year-old man who complained of pain in the lower cervical spine, difficulties in micturition and sexual impotence. The diagnosis was suspected at the MRI which showed a lesion with a paramagnetic signal and was confirmed by the histological examination. The resection was complete and the course has been satisfactory after 19 months follow-up.

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

    To explore the association between the genetic variant of E-cadherin gene and endometriosis-related infertility. Case-control study. University hospital. Five hundred eighty-nine women with ovarian endometriosis including 127 patients with primary infertility and 589 female controls in northern China. None. Single nucleotide polymorphisms (SNPs) in the promoter region, exons, and the 3' untranslated region of the E-cadherin gene were identified by direct sequencing in patients with ovarian endometriosis and with polymerase chain reaction (PCR). Six candidate SNPs (rs16260, rs28372783, rs1801552, rs1801026, rs8049282, and rs13689) were genotyped by PCR and ligase detection reaction. The results revealed a significant association of rs8049282 SNP on E-cadherin gene with endometriosis-related infertility. When compared with control women or endometriosis patients who had a history of successful fertility, the CC genotype of rs8049282 may significantly increase the risk of primary infertility in patients with ovarian endometriosis (adjusted odds ratio [OR] = 2.70, 95% confidence interval [CI] 1.45-5.00; OR = 2.54, 95% CI 1.45-4.44, respectively). Our results suggested that genetic variants on the E-cadherin gene may be involved in endometriosis-related infertility. The rs8049282 SNP of the E-cadherin gene may be a potential molecular marker for the development of primary infertility in northern Chinese women with ovarian endometriosis.

    The purpose of the present study was to investigate the possible association between Excision repair cross-complementing group 1 (ERCC1) score and platinum resistance in first-line chemotherapy for ovarian cancer. ERCC1 Expression was determined using immunohisto-chemistry in 68 patients with platinum-responding tumor and 30 with platinum-resistant tumors. The primary end-point of this study was the association between the expression of ERCC1 protein with resistance to standard platinum-based chemotherapy in primary ovarian cancer. In pairwise comparisons, the overall survival (OS) for patients with ovarian cancer, who were non-responders to platinum-based chemotherapy with low or intermediate H-score for ERCC1 was better than that of non-responders with high H-score for ERCC1 [median OS=21 (16.8-25.2 months) and 28 (14.6-41.4 months) vs. 15 months (6.2-23.8 months), p-value=0.048, and p-value=0.017, respectively]. There were no significant differences in the progression-free survival between those with low, intermediate and high H-score for ERCC1. There is no statistically significant relationship between ERCC1 score and response to platinum-based chemotherapy in patients with primary ovarian cancer.

    High-grade serous carcinoma (HGSC) is the most common and fatal form of ovarian cancer. While most tumours are highly sensitive to cytoreductive surgery and platinum- and taxane-based chemotherapy, the majority of patients experience recurrence of treatment-resistant tumours. The clonal origin and mutational adaptations associated with recurrent disease are poorly understood. We performed whole exome sequencing on tumour cells harvested from ascites at three time points (primary, first recurrence, and second recurrence) for three HGSC patients receiving standard treatment. Somatic point mutations and small insertions and deletions were identified by comparison to constitutional DNA. The clonal structure and evolution of tumours were inferred from patterns of mutant allele frequencies. TP53 mutations were predominant in all patients at all time points, consistent with the known founder role of this gene. Tumours from all three patients also harboured mutations associated with cell cycle checkpoint function and Golgi vesicle trafficking. There was convergence of germline and somatic variants within the DNA repair, ECM, cell cycle control, and Golgi vesicle pathways. The vast majority of somatic variants found in recurrent tumours were present in primary tumours. Our findings highlight both known and novel pathways that are commonly mutated in HGSC. Moreover, they provide the first evidence at single nucleotide resolution that recurrent HGSC arises from multiple clones present in the primary tumour with negligible accumulation of new mutations during standard treatment.

    Systematic registration of non-malignant central nervous system (CNS) tumors is a rare practice among European cancer registries. Thus, the real burden of all CNS tumors across Europe is underestimated. The Girona Cancer Registry provides here the first data on CNS tumor incidence and survival trends in Spain for all histological types, including malignant and non-malignant tumors. Data on all incident cases of primary CNS tumors notified to the Girona population-based cancer registry from 1994 to 2013 (n=2,131) were reviewed. Incidences rates (IRs) were standardized to the 2013 European population and annual percentage changes (EAPC) were estimated using a piecewise log linear model. 1- and 5-year observed (OS) and relative survival (RS) were also calculated. Results were expressed by sex, age-group, histological subtype and behavior. The overall IR was 16.85 and increased across the period of study (EAPC=+2.2%). The proportion and IRs of malignant (50.2%; IR=9.35) and non-malignant cases (49.8%; IR=9.14) were similar; however, non-malignant tumors were more frequent in women (sex ratio=0.63). The most frequently reported histologies were meningioma (27.6%; IR=5.11) and glioblastoma (22.2%; IR=4.15), which also accounted for the highest and lowest 5-year RS (80.2%; 3.7%, respectively). Globally, 5-year RS was lower in men (42.6% vs. 58.3%, respectively) and in the elderly (64.9% for 0-14years vs. 23.0% for >74years). This study presents a comprehensive overview of the epidemiology of malignant and non-malignant CNS primary tumors from the well-established region-wide Girona Cancer Registry (1994-2013). Incidence rates were recovered for all histologies. Survival is still dramatically associated to both age and histological subtype. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Surgery is the cornerstone for clinical management of patients with borderline ovarian tumors (BOT). As these patients have an excellent overall prognosis, perioperative morbidity is the critical point for decision making when the treatment strategy is developed and the primary surgical approach is defined. Clinical and surgical parameters of patients undergoing surgery for primary BOT at our institutions between 1993 and 2008 were analyzed with regard to perioperative morbidity depending on the surgical approach (laparotomy vs. laparoscopy). A total of 105 patients were analyzed (44 with primary laparoscopy [42%], 61 with primary laparotomy [58%]). Complete surgical staging was achieved in 33 patients at primary surgical approach (31.4%) frequently leading to formal indication of re-staging procedures. Tumor rupture was significantly more frequent during laparoscopy compared to laparotomy (29.5% vs. 13.1%, p = 0.038) but no other intraoperative complications were seen in laparoscopic surgery in contrast to 7 of 61 laparotomies (0% vs. 11.5%, p = 0.020). Postoperative complication rates were similar in both groups (19.7% vs. 18.2%, p = 0.848). Irrespective of the surgical approach, surgical management of BOT has acceptable rates of perioperative complications and morbidity. Choice of initial surgical approach can therefore be made independent of complication-concerns. As the recently published large retrospective AGO ROBOT study observed similar oncologic outcome for both approaches, laparoscopy can be considered for staging of patients with BOT if this appears feasible. An algorithm for the surgical management of BOT patients has been developed.

    Malignant psoas syndrome (MPS) is an uncommon condition first described by Stevens et al. MPS is caused by malignant infiltration of the psoas muscle and adjacent nerves and is characterised by (fixed) flexion deformity of the ipsilateral hip and proximal lumbosacral plexopathy. It has previously been described in relation to metastatic carcinoma, melanoma and liposarcoma, as well as non-Hodgkins lymphoma. We present the case of a 68-year-old woman with a sarcoma arising in the left psoas muscle at the level of L4 who presented with symptoms of MPS. To the authors’ knowledge this is the first case of MPS arising from a primary sarcoma of the iliopsoas compartment. The patient underwent presurgical radiotherapy, with a significant improvement in pain control without an increase in analgesic medications. We discuss the aetiology of MPS and the role of radiotherapy in the treatment of this rare syndrome. PMID:28361070

    Additional primary malignancies in patients with gastrointestinal stromal tumor (GIST) is not only common but of growing interest in the scientific literature. This association is of great importance in terms of clinical challenge, diagnosis and therapy as well as for the prognosis impact it implies. In the published series there is a tendency to group these patients to determine the specific and distinguishable characteristics of GIST associated with other malignancies. On the other hand, there is no general consensus or unified classification. This classification would be of great interest, as it would unify criteria, agree groups to compare different series and demonstrate whether the aetiology underlying both tumours and the GIST's own characteristics really vary according to the type in question. We undertook a medical literature review and proposed a new classification for patients with GIST associated with other tumours. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    A 37-year-old female smoker without a history of exposure to asbestos was referred to our hospital with persistent pericardial effusion. Chest computed tomography imaging examination revealed an irregular thickened pericardium with large amounts of pericardial effusion and a small pleural effusion. Fluorodeoxyglucose (FDG) positron emission tomography imaging demonstrated intrapericardial FDG accumulation. Blood tests revealed an increase in serum mesothelin levels. Examination of a surgically resected specimen revealed a grayish-white thickening of the pericardium, with a straw-colored mucinous pericardial effusion. Histopathological examination confirmed the diagnosis of epithelioid malignant mesothelioma. Although the patient's condition temporarily improved, with decreased levels of serum mesothelin during chemotherapy with carboplatin and pemetrexed, she succumbed to cardiac tamponade 18 months after the initial onset of the symptoms. Primary malignant pericardial mesothelioma (PMPM) is an extremely rare and refractory disorder. Thus, an early definitive diagnosis and timely treatment are crucial for the management of PMPM.

    The number of patients with primary malignant bone and soft tissue tumors in Japan is increasing in line with the increasing size of the elderly population. The aim of the present study was to determine the prognostic factors of primary malignant bone or soft tissue tumors in elderly patients. Clinical data was obtained from 90 patients, aged ≥65 years, with primary malignant bone or soft tissue tumors (bone, 20 cases; and soft tissue, 70 cases), treated at the Osaka City University Hospital between 1993 and 2013. Clinical information prior to treatment and tumor type, location, size, depth, grade and American Society of Anesthesiologists-Physical Status (ASA-PS) score were evaluated in order to identify prognostic factors using the Cox proportional hazards regression model. In addition, 5-year survival rates were evaluated using the Kaplan-Meier method. The average follow-up period was 44.8 months and the 5-year overall survival rate was 77.5%. In the multivariate analysis, ASA-PS score and high-grade sarcoma were found to be associated with a poorer overall survival. No significant differences were observed between the patient group aged 65–74 years and that aged ≥75 years. In general, aging is associated with physically reduced function and an increased prevalence of comorbidities. It was therefore expected that increasing age may be a predictive factor for poor prognosis. However, the results of the present study suggested that ASA-PS score and tumor grade were significant factors associated with poor prognosis, whereas increasing age was not. Therefore, the treatment of elderly patients with primary bone and soft tissue tumors should not be based on age. PMID:26622753

    High-grade serous ovarian cancer (HGSC) is characterized by poor outcome, often attributed to the emergence of treatment-resistant subclones. We sought to measure the degree of genomic diversity within primary, untreated HGSCs to examine the natural state of tumour evolution prior to therapy. We performed exome sequencing, copy number analysis, targeted amplicon deep sequencing and gene expression profiling on 31 spatially and temporally separated HGSC tumour specimens (six patients), including ovarian masses, distant metastases and fallopian tube lesions. We found widespread intratumoural variation in mutation, copy number and gene expression profiles, with key driver alterations in genes present in only a subset of samples (eg PIK3CA, CTNNB1, NF1). On average, only 51.5% of mutations were present in every sample of a given case (range 10.2–91.4%), with TP53 as the only somatic mutation consistently present in all samples. Complex segmental aneuploidies, such as whole-genome doubling, were present in a subset of samples from the same individual, with divergent copy number changes segregating independently of point mutation acquisition. Reconstruction of evolutionary histories showed one patient with mixed HGSC and endometrioid histology, with common aetiologic origin in the fallopian tube and subsequent selection of different driver mutations in the histologically distinct samples. In this patient, we observed mixed cell populations in the early fallopian tube lesion, indicating that diversity arises at early stages of tumourigenesis. Our results revealed that HGSCs exhibit highly individual evolutionary trajectories and diverse genomic tapestries prior to therapy, exposing an essential biological characteristic to inform future design of personalized therapeutic solutions and investigation of drug-resistance mechanisms.

    Malignant ovarian tumours of the fibrothecoma group are rare. The clinicopathological features of a case of ovarian malignant fibrothecoma in which there was metastatic disease in the small intestine and peritoneum at presentation are described. A number of differential diagnoses were considered but positive immunohistochemical staining of the resected ovarian and small intestinal neoplasms with anti-inhibin was of value in confirming a sex cord-stromal tumour and in excluding other lesions. The two tumours were also ultrastructurally identical. Classical malignant fibrothecomas are said to show four or more mitotic figures per 10 high power fields (HPF). Although the intestinal secondary was mitotically active, the primary ovarian tumour contained only one to two mitoses per 10 HPF, showing that formal mitotic counts are not an absolute indicator of malignant behaviour in this group of tumours.

    Current guidelines recommend empirical, noninvasive approaches to manage dyspeptic patients without alarm symptoms, but concerns about missed lesions persist; the cost savings afforded by noninvasive approaches must be weighed against treatment delays. We investigated the prevalence of malignancies and other serious abnormalities in patients with dyspepsia and the cost of detecting these by endoscopy. We studied 2741 primary-care outpatients, 18-70 years in age, who met Rome II criteria for dyspepsia. Patients with alarm features (dysphagia, bleeding, weight loss, etc) were excluded. All patients underwent endoscopy. The cost and diagnostic yield of an early endoscopy strategy in all patients were compared with those of endoscopy limited to age-defined cohorts. Costs were calculated for a low, intermediate, and high cost environment. Endoscopies detected abnormalities in 635 patients (23%). The most common findings were reflux esophagitis with erosions (15%), gastric ulcers (2.7%), and duodenal ulcers (2.3%). The prevalence of upper gastrointestinal malignancy was 0.22%. If all dyspeptic patients 50 years or older underwent endoscopy, 1 esophageal cancer and no gastric cancers would have been missed. If the age threshold for endoscopy were set at 50 years, at a cost of $500/endoscopy, it would cost $82,900 (95% CI, $35,714-$250,000) to detect each case of cancer. Primary care dyspeptic patients without alarm symptoms rarely have serious underlying conditions at endoscopy. The costs associated with diagnosing an occult malignancy are large, but an age cut-off of 50 years for early endoscopy provides the best assurance that an occult malignancy will not be missed.

  16. Therapeutic strategies in epithelial ovarian cancer

    2012-01-01

    Ovarian cancer is the most lethal gynecologic malignancy. It appears that the vast majority of what seem to be primary epithelial ovarian and primary peritoneal carcinomas is, in fact, secondary from the fimbria, the most distal part of the fallopian tube. Treatment of epithelial ovarian cancer is based on the combination of cytoreductive surgery and combination chemotherapy using taxane and platinum. Although clear cell type is categorized in indolent type, it is known to show relatively strong resistance to carboplatin and paclitaxel regimen and thus poor prognosis compared to serous adenocarcinoma, especially in advanced stages. Irinotecan plus cisplatin therapy may effective for the clear cell adenocarcinoma. The larger expectation for improved prognosis in ovarian carcinoma is related to the use of the new biological agents. One of the most investigated and promising molecular targeted drugs in ovarian cancer is bevacizumab, a monoclonal antibody directed against VEGF. PARP inhibitor is another one. A few recent studies demonstrated positive results of bevacizumab on progression-free survival in ovarian cancer patients, however, investigation of molecular targeting drugs in patients with ovarian cancer are still underway.

A regional population-based cohort study of women diagnosed with primary ovarian and fallopian tube cancers and included in the Swedish Quality Registry (SQR) during 2008-2013 in a region where primary care of advanced stages was centralized in 2011. Surgical, oncological characteristics, outcomes, follow-ups and relative survivals were analyzed. There were 817 women diagnosed with ovarian and fallopian tube cancers during 2008-2013 and 523 were classified as FIGO stage III-IV and further analyzed. Primary debulking surgery (PDS) was performed in 81% and neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) in 11%. Complete cytoreduction at PDS was performed in 37% before compared to 49% after centralization (p<0.03). The chemotherapy protocols were identical in the cohorts and they received and completed the planned chemotherapy equally. The time interval between PDS and chemotherapy was 36days (median) before compared to 24days after centralization (p<0.01). The relative 3-year survival rate in women treated by PDS was 44% compared to 65% after centralization and the estimated excess mortality rate ratio (EMRR) was reduced (RR 0.58; 95% CI 0.42-0.79). Comparing the complete cohorts before and after centralization, regardless primary treatment, the relative 3-year survival rate increased from 40% to 61% with reduced EMRR (RR 0.59; 95% CI 0.45-0.76). Centralized primary care of advanced ovarian and fallopian tube cancers increases complete cytoreduction, decreases time interval from PDS to chemotherapy and improves relative survival significantly.

    Metastatic breast carcinoma to the ovary is sometimes difficult to differentiate from primary ovarian carcinoma. This problem is often encountered in breast carcinoma patients who develop adnexal masses. ER and PR can be positive in a high percentage of breast and ovarian carcinomas, and therefore cannot be used in the differential diagnosis of these entities. WT1 and CA125 have been identified as possible markers for ovarian cancer. However, no studies have been done that specifically compare the immunophenotype of breast carcinoma metastatic to ovary with that of primary ovarian cancer. Thirty-nine cases of metastatic breast carcinoma to the ovary, 36 primary breast carcinomas, and 42 primary ovarian carcinomas were examined immunohistochemically for the expression of WT1, CA125, carcinoembryonic antigen, MUC2, MUC1, and GCDFP. The percentage of cells stained and the intensity of staining were recorded. Thirty-two ovarian carcinomas (76%) were positive for WT1, including 31 of 33 (94%) serous carcinomas. Most of them had strong and diffuse staining. None of the breast cancers either primary or metastatic to the ovary expressed WT1. Thirty-eight (90%) ovarian carcinomas were positive for CA125, most of them with strong and diffuse staining. Most breast carcinomas were negative for CA125, with only 6 (16%) of the primary ones and 5 (12%) of the metastatic showing weak and focal positivity. All ovarian carcinomas were negative for GCDFP. Five primary breast cancers (14%) and 17 (43%) metastatic to the ovary were positive for GCDFP. Nine (21%) ovarian carcinomas, 8 (22%) primary breast carcinomas, and 13 (33%) metastatic to the ovary were positive for carcinoembryonic antigen. Almost all tumors examined were positive for MUC1 (100% ovarian carcinomas, 100% primary breast carcinomas, and 95% metastatic breast carcinomas to ovary). MUC2 was positive in 10 (24%) ovarian carcinomas, 3 (8%) primary breast cancers, and 12 (30%) metastases to the ovary. The presence of

    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

    Patients with malignant glioma who are also diagnosed with one or more primary neoplasms of other organs present a unique challenge in both determining prognosis and clinical management. The overlapping impact of the malignancies and their treatment result in confounding variables that may adversely affect optimal management of such patients. Additionally, the glioma-related characteristics and survival outcome of these patients is not well-defined. In this retrospective chart and data review from our longitudinal database, we identified patients with malignant glioma including anaplastic glioma and glioblastoma, diagnosed between January 2005 and June 2011, who were also diagnosed with other non-CNS primary neoplasms. Patients with known genetic syndromes were excluded. The data was analyzed to determine the clinical characteristics and glioma-related survival. A total of 204 patients with malignant glioma (165 glioblastoma and 39 anaplastic glioma) were identified. There was no significant difference in the overall survival or progression-free survival between patients with malignant glioma plus non-CNS primary neoplasm when compared with patients with malignant glioma only. In patients with glioblastoma and non-CNS malignancy, the duration between diagnosis of glioblastoma and non-CNS neoplasms did not significantly alter glioma-related survival. Patients with malignant glioma who were diagnosed with other non-CNS malignancy have survival outcome comparable to those with malignant glioma only. The duration between diagnosis of glioblastoma and diagnosis of non-CNS neoplasms did not affect survival. Further prospective studies specifically addressing survival and molecular characteristics of patients with malignant glioma plus non-CNS cancers are recommended.

    To present and analyze the clinical characteristics, treatment, and treatment options for a patient with primary malignant melanoma of the vagina and review of literature. A 71-year-old patient with a history of vaginal bleeding caused by four tumor growths located in the vagina is presented. The size of each formation was about 2 cm. Three of them were located in the proximal two-thirds of the anterior wall of the vagina and one in the distal third. Excisional biopsy was performed of the lesion located near the entrance of the vagina. Histopathological examination revealed that it was a malignant melanoma of the vagina, which was confirmed immunohistochemically. After ruling out a tumor of an unknown primary site, the patient underwent radical hysterectomy type IV total vaginectomy and pelvic lymph node dissection. Hystological examination proved a clinically asymptomatic melanoma lesion of the uterine cervix. After surgery, the patient was given chemotherapy with Dacarbasine and monthly immunotherapy with BCG vaccine. The patient survived 21 months after surgery without developing a local relapse and died of distant metastases in the spine. Radical surgery for primary melanoma of the vagina is a secure way of achieving locoregional control of multifocal disease. The wide local excision can be used in unifocal lesions with security in achieving clean surgical margins.

    Ovarian cancer is the most lethal gynecological malignancy. It is usually diagnosed at a late stage, with a 5-yr survival rate of <30%. The majority of ovarian cancer cases are diagnosed after tumors have widely spread within the peritoneal cavity, limiting the effectiveness of debulking surgery and chemotherapy. Owing to a substantially lower survival rate at late stages of disease than at earlier stages, the major cause of ovarian cancer deaths is believed to be therapy-resistant metastasis. Although metastasis plays a crucial role in promoting ovarian tumor progression and decreasing patient survival rates, the underlying mechanisms of ovarian cancer spread have yet to be thoroughly explored. For many years, researchers have believed that ovarian cancer metastasizes via a passive mechanism by which ovarian cancer cells are shed from the primary tumor and carried by the physiological movement of peritoneal fluid to the peritoneum and omentum. However, the recent discovery of hematogenous metastasis of ovarian cancer to the omentum via circulating tumor cells instigated rethinking of the mode of ovarian cancer metastasis and the importance of the “seed-and-soil” hypothesis for ovarian cancer metastasis. In this review we discuss the possible mechanisms by which ovarian cancer cells metastasize from the primary tumor to the omentum, the cross-talk signaling events between ovarian cancer cells and various stromal cells that play crucial roles in ovarian cancer metastasis, and the possible clinical implications of these findings in the management of this deadly, highly metastatic disease.

    Due to the poor response of primary malignant bone tumors to adjuvant therapies, surgical resection performed in an en bloc fashion with free margins remains the best option for long-term recurrence-free survival of patients harboring such lesions. In this article the authors provide a stepwise review of the technical details involved in the performance of en bloc resections of tumoral lesions in the cervical spine. Due to the anatomical peculiarities of the cervical spine related to the presence of functional nerve roots as well as the vertebral arteries, en bloc resections in this region remains a challenging surgical procedure.

    Primary acquired melanosis (PAM) is an acquired pigmentation of the conjunctival epithelium, a preinvasive pigmented lesion. When it is associated with cellular atypia it can lead to the developement of melanoma. We report a case report of malignant melanoma of the conjuntiva, which arrised from the conjuntival PAM. The disease was too extensive for ocular conservation, therefore exenteration was performed. This case highlights the need for regular follow-up of patients with melanocytic lesions of the ocular adnexa, and particular attention to the surgical technique, and careful follow-up to detect further disease activity.

    A 34-year-old patient with a swelling over the upper eyelid for nearly 1 year was seen in our clinic. The history, examination and investigations were suggestive of a benign lacrimal gland tumor. The tumor and lacrimal gland were resected. Subsequent histopathological examination revealed the tumor was a primary ductal adenocarcinoma of the lacrimal gland. This is a very rare tumor with less than half a dozen cases reported so far. This case report is being presented to highlight an unusual presentation of this rare malignancy. PMID:26669339

    The patient, a 44-year-old female, was admitted to our department because of right hemiparesis and left oculomotor nerve palsy on February 7, 1986. Neither lymphadenopathy nor hepatosplenomegaly was present. She had been treated with prednisolone for systemic lupus erythematosus (SLE) for one and a half year before admission. The CT scan revealed a homogeneously enhanced mass lesion from the midbrain through the thalamus on the right side. The whole body gallium scintigram showed no abnormal uptake except in the brain. Stereotaxic biopsy was performed. Histopathological diagnosis was malignant lymphoma, diffuse, large cell type (International Working Formulation). The enhanced mass lesion disappeared after radiation therapy. Subsequently, she received chemotherapy. She remained well until May 1988 when she died because of the systemic lymphadenopathy. The association of malignant lymphoma and SLE has appeared occasionally in the literature. Primary intracerebral malignant lymphoma associated with SLE is much rarer but it should be considered in the differential diagnosis of symptoms of the central nervous system in a patient with SLE. Therefore, biopsy of a cerebral mass lesion is mandatory if appropriate therapy such as radiation and chemotherapy is to be administered.

    Malignant fibrous histiocytoma (MFH) is a rare primary neoplasm that constitutes less than 1% of the malignant tumors of bone, and involvement of the skull is very rare. We present a case of malignant fibrous histiocytoma of the skull, presenting an intraosseous lesion in a 43-yr-old woman. She had a rapidly growing, tender mass in the right parietal region. A plain radiograph showed an osteolytic lesion of the right parietal bone. Magnetic resonance imaging revealed that the lesion showed heterogeneous low signal intensity on T1-weighted images and slightly high signal intensity on T2-weighted images. No evidence of an extraosseous extension to the adjacent dura and soft tissue was found, and a wide excision of the parietal bone was performed. Histologically, the tumor was a typical MFH displaying pleomorphic spindle cells in a storiform pattern. The results of immunohistochemical stainings revealed that the tumor cells were positive for vimentin, alpha-1-antitrypsin, and p53, and negative for smooth muscle actin, S100 protein, desmin, and MyoD1. Three months later, a mainly cystic, recurrent mass was developed at the previously operated site. Before the resection, we first performed the percutaneous aspiration cytology, revealing diagnostic multinucleated pleomorphic cells. Thereafter, she had to receive repetitive resections of recurrent or residual lesions, and she died of postoperative meningoencephalitis two years after the first operation. PMID:12923345

    Primary immunodeficiencies (PIDs) are commonly characterized by an increased susceptibility to specific infections and, in certain instances, a higher than usual incidence of malignancies. Although improved diagnosis and early treatment of PIDs have reduced early morbidity and mortality from infection, the development of cancer remains a significant cause of premature death. The emergence of cancer in patients with PIDs often results from impairments in the immune response that lead to weakened surveillance against oncogenic viruses, premalignant or malignant cells, or both. Here we review the clinical and biologic features of several PIDs associated with enhanced susceptibility to viral infections and cancer, including X-linked lymphoproliferative disease; IL-2-inducible T-cell kinase deficiency; epidermodysplasia verruciformis; warts, hypogammaglobulinemia, infections, and myelokathexis syndrome; autosomal recessive hyper-IgE syndrome; X-linked agammaglobulinemia; and common variable immunodeficiency. It is of importance that we gain in-depth insights into the fundamental molecular nature of these unique PIDs to better understand the pathogenesis of virus-associated malignancies and to develop innovative therapeutic strategies.

    The impact of cancer therapy on the reproductive potential of patients is increasingly recognized because survival rates of patients have clearly improved in recent years. Different fertility preservation methods, either generally accepted or still experimental, are currently available, and counseling of patients requires a delicate balance between the efficacy and side effects of the proposed method and the characteristics of both the tumor and the therapy. Deeper knowledge of the effects of cancer therapy on the reproductive potential of patients over time is required to identify the most appropriate fertility preservation method. In this paper, we report a case-control study in which female patients who were diagnosed with hematological malignancies and treated with chemotherapy and/or radiotherapy were compared with age-matched controls in terms of ovarian reserve, as measured by ultrasound examination and hormonal status. By stratifying patients for gonadotoxicity of the therapy received and time elapsed from the end of the therapy, we report that patients treated with low gonadotoxic therapies, while being similar to age-matched controls in their ovarian reserve when evaluated within a few years from the end of the therapy, show a clear impairment over longer times. We also report that anti-Müllerian hormone is the most sensitive hormonal parameter in detecting changes in ovarian reserve when compared with follicle-stimulating hormone or inhibin-B. This study stresses the importance of accurate counseling at the time of diagnosis of cancer and emphasizes the risks of infertility with low gonadotoxic therapies that may reduce the reproductive window of survivors.

    Preclinical studies in ovarian cancer have demonstrated upregulation of the Wnt/β-catenin pathway promoting tumor proliferation and chemoresistance. Our objective was to evaluate the effect of the Wnt/β-catenin pathway inhibitor, WNT974, in primary ovarian cancer ascites cells. Ascites cells from patients with papillary serous ovarian cancer were isolated and treated with 1 μM WNT974±100 μM carboplatin. Viability was evaluated with the ATPlite assay. The IC50 was calculated using a dose-response analysis. Immunohistochemistry (IHC) was performed on ascites cells and tumor. Expression of R-spondin 2 (RSPO2), RSPO3, PORCN, WLS, AXIN2, and three previously characterized RSPO fusion transcripts were assessed using Taqman assays. Sixty ascites samples were analyzed for response to WNT974. The ascites samples that showed a decrease in ATP concentration after treatment demonstrated no difference from the untreated cells in percent viability with trypan blue staining. Flow cytometry demonstrated fewer cells in the G2 phase and more in the G1 and S phases after treatment with WNT974. Combination therapy with WNT974 and carboplatin resulted in a higher percentage of samples that showed ≥30% reduction in ATP concentration than either single drug treatment. IHC analysis of Wnt pathway proteins suggests cell cycle arrest rather than cytotoxicity after WNT974 treatment. QPCR indicated that RSPO fusions are not prevalent in ovarian cancer tissues or ascites. However, higher PORCN expression correlated to sensitivity to WNT974 (P=0.0073). In conclusion, WNT974 produces cytostatic effects in patient ascites cells with primary ovarian cancer through inhibition of the Wnt/β-catenin pathway. The combination of WNT974 and carboplatin induces cytotoxicity plus cell cycle arrest in a higher percentage of ascites samples than with single drug treatment. RSPO fusions do not contribute to WNT974 sensitivity; however, higher PORCN expression indicates increased WNT974 sensitivity.

  15. Use of model systems to understand the etiology of fragile X-associated primary ovarian insufficiency (FXPOI)

    PubMed Central

    2014-01-01

    Fragile X-associated primary ovarian insufficiency (FXPOI) is among the family of disorders caused by the expansion of a CGG repeat sequence in the 5' untranslated region of the X-linked gene FMR1. About 20% of women who carry the premutation allele (55 to 200 unmethylated CGG repeats) develop hypergonadotropic hypogonadism and cease menstruating before age 40. Some proportion of those who are still cycling show hormonal profiles indicative of ovarian dysfunction. FXPOI leads to subfertility and an increased risk of medical conditions associated with early estrogen deficiency. Little progress has been made in understanding the etiology of this clinically significant disorder. Understanding the molecular mechanisms of FXPOI requires a detailed knowledge of ovarian FMR1 mRNA and FMRP’s function. In humans, non-invasive methods to discriminate the mechanisms of the premutation on ovarian function are not available, thus necessitating the development of model systems. Vertebrate (mouse and rat) and invertebrate (Drosophila melanogaster) animal studies for the FMR1 premutation and ovarian function exist and have been instrumental in advancing our understanding of the disease phenotype. For example, rodent models have shown that FMRP is highly expressed in oocytes where it is important for folliculogenesis. The two premutation mouse models studied to date show evidence of ovarian dysfunction and, together, suggest that the long repeat in the transcript itself may have some pathological effect quite apart from any effect of the toxic protein. Further, ovarian morphology in young animals appears normal and the primordial follicle pool size does not differ from that of wild-type animals. However, there is a progressive premature decline in the levels of most follicle classes. Observations also include granulosa cell abnormalities and altered gene expression patterns. Further comparisons of these models are now needed to gain insight into the etiology of the ovarian

    Population-based data on the development of kidney cancer as a second malignant neoplasm following the diagnosis of other common malignancies are rare. This clinical scenario has been evaluated within the Surveillance, Epidemiology, and End Results (SEER) database. The SEER-9 database (1973-2013) was queried using the SEER*Stat program to determine the standardized incidence ratios (SIRs) of kidney cancer development following each one of 10 common invasive malignancies (colorectal, breast, prostate, lung, thyroid, corpus uteri, urinary bladder, kidney/renal pelvis, cutaneous melanoma, and non-Hodgkin lymphoma). The following data were collected for patients with a second renal cancer: age at diagnosis of the second renal cancer; gender, race, and histology of the second primary renal cancer; SEER historic stage of the second primary renal cancer; and method of diagnostic confirmation of the second primary cancer. A total of 10,145 kidney cancers were observed. Elevated SIRs for kidney cancer were noted for all 10 evaluated malignancies in the initial 12 months after diagnosis. The SIRs remained elevated 12 to 59 months after diagnosis for all cancers except breast and prostate cancers. Increased risks persisted 60 to 119 months beyond diagnosis for renal cancer (SIR, 4.13), thyroid cancer (SIR, 2.30), and non-Hodgkin lymphoma (SIR, 1.40); and 120+ months for renal cancer (SIR, 3.60), thyroid cancer (SIR, 1.90), and non-Hodgkin lymphoma (SIR, 1.27). Increased kidney cancer risk after non-Hodgkin lymphoma was not related to radiation therapy. Papillary renal cell carcinoma has the highest SIRs for subsequent kidney cancers. Many common cancers are associated with an increased risk of kidney cancer development within the first 5 years after their diagnosis. Although this can be partly interpreted by increased rates of surveillance tests, radiotherapy effects, or genetic associations for some cancers, additional research is required to explain the persistently

    Primary well differentiated keratinising Squamous Cell Carcinoma (SCC) is a rare gall bladder malignancy accounting for 3.3% of all gall bladder carcinomas. Here we present a case of a 70-year-old female with complaints of dyspepsia and right upper quadrant pain for 3 months. Ultrasonography showed gall stones along with thickened and irregular gall bladder wall. Grossly an exophytic growth was noted involving large part of the body of gall bladder. Histological features were of well differentiated SCC with extensive keratinisation involving full thickness of the wall. No glandular component was seen. Metastasis from other primary was ruled out after thorough work-up. SCC of gall bladder has an infiltrative growth pattern and behaves aggressively. Early diagnosis plays the most important role in increasing the survival. PMID:27790451

    MAGE-C1/CT7, NY-ESO-1, GAGE and MAGE-A4 are members of the cancer/testis (CT) antigen family, which have been proposed as potential targets for cancer immunotherapy. To determine the prevalence and biologic relevance of the novel CT antigen MAGE-C1/CT7 and other antigens, 36 ovarian borderline tumours (BTs), 230 primary ovarian carcinomas (OCs) and 80 recurrent OCs were immunohistochemically analysed using the monoclonal antibodies CT7-33 (MAGE-C1/CT7), E978 (NY-ESO-1), clone 26 (GAGE) and 57B (MAGE-A4). Positivity of at least one CT antigen was present in 39.5 % (81/205) of primary OC and in 50 % (26/52) of all recurrences. Expression of the novel CT antigen MAGE-C1/CT7 was most commonly seen with positivity in 24.5 % of primary and 35.1 % of recurrent OC. MAGE-A4, GAGE and NY-ESO-1 expressions were seen in 22.7, 13.9 and 7.1 % of primary and 22.6, 17.5 and 8.9 % of recurrent OC, respectively. Analysis of histological subtypes (serous, endometrioid, clear cell, mucinous and transitional) exhibited variable expression with negativity in all mucinous OC. High-grade serous OC revealed CT antigen expression in 5.6 to 28 % with MAGE-C1/CT7 being the most frequent, but without correlation with stage or overall survival. MAGE-C1/CT7 expression and coexpression of CT antigens were significantly correlated with grade of endometrioid OC. None of the BT showed CT antigen expression. No significant correlation was seen with stage, overall survival or response to chemotherapy. In summary, CT antigens are expressed in a certain subset of OC with no expression in BT or OC of mucinous histology. These findings may have implications for the design of polyvalent vaccination strategies for ovarian carcinomas.

    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

    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

    2012-01-01

    Background Primary extracranial meningiomas (PEMs) originating from the nasal septum are extremely rare, as are extracranial metastases of meningiomas. Case presentation A 44-year-old male presented with a 2-month history of left-side nasal obstruction and frequent episodes of epistaxis. A friable mass originating from the nasal septum was resected completely via an endoscopic endonasal approach. According to WHO criteria, the tumor was diagnosed as an atypical meningioma radiologically and histopathologically. Two years later, a tumor recurred at the primary site with the same histopathological findings, and the patient was given local external radiotherapy (6840 cGy in 38 fractions). Two months after this local recurrence, a left anterior chest wall mass and a left parietal area scalp mass were observed. The subcutaneous mass was resected and showed histological evidence of malignant transformation. Several months after the last operation, the patient died. Conclusions We describe the clinical, radiological, and bio-pathological features of this unique case and review the literature on atypical PEMs originating in the nasal septum. To our knowledge, this is the first reported case of an atypical PEM originating from the nasal septum that recurred with malignant transformation and extracranial metastasis. PMID:22759338

    Several aspects of calcium metabolism were studied in five patients during the surgical exploration of malignant tumours associated with humorally-mediated hypercalcaemia. Before operation in all patients the renal tubular threshold for calcium reabsorption was raised and the threshold for renal tubular phosphate reabsorption depressed. On removal of the primary tumour in three cases, serum calcium returned to normal, renal calcium threshold fell, renal phosphate threshold rose, but urinary hydroxyproline excretion did not change. In two patients where the tumour proved inoperable, serum calcium remained elevated and no changes in renal calcium threshold or phosphate threshold occurred. Histomorphometry carried out on biopsy specimens from four patients showed normal bone resorption in three, and slightly increased resorption in one, without depression of osteoblastic bone formation. It is suggested that hypercalcaemia in these patients resulted mainly from an alteration in renal calcium threshold caused by a humoral substance released by tumour cells. Correction of hypercalcaemia on removal of the primary tumour was achieved rapidly and could be explained principally by a reduction in renal calcium threshold with increased loss of calcium into the urine. These data contrast with those of many previous studies which have emphasised the predominant role of accelerated osteoclastic bone resorption as the principal cause of hypercalcaemia in malignancy and suggest that a renal effect of the putative humoral agent may predominate in some cases.

    A prospective phase II clinical treatment trial of 13 patients with previously untreated optimal surgically resected (< or = 1 cm stage III ovarian carcinoma was conducted at the University of Michigan Hospitals. The treatment regimen after surgical resection consisted of chemotherapy followed by whole abdomen and pelvic radiation therapy. Chemotherapy consisted of four cycles of 50 mg/m2 cisplatin and 1000 mg/m2 cytoxan. This was followed by whole abdomen radiation therapy with a planned total dose of 30 Gy to the whole abdomen and then a 20-Gy boost to the pelvis. Six of 13 patients received a paraaortic radiation boost. There was minimal acute toxicity, but delayed toxicity was encountered with 38% of patients developing a bowel obstruction. Nine patients had reassessment laparotomy: 5 second-look laparotomies and 4 laparotomies for bowel obstruction. Two of these 9 patients died of septic complications after surgery. Nine patients died with disease, 1 patient is alive with advanced disease, and only 3 patients are alive with no evidence of disease. Actuarial 3-year survival and progression-free interval was 26 and 20%, respectively. Primary treatment consisting of sequential chemotherapy and whole abdomen radiation in the dose and scheme utilized did not improve the survival over what could be expected utilizing one of these treatments alone. It was associated with increased delayed toxicity.

The present study was designed to determine vitamin D, copper, zinc, metabolic parameters [insulin, homeostasis model of assessment-insulin resistance (HOMA-IR)], inflammation parameters such as procalcitonin and high sensitivity C reactive protein (hs-CRP), and lipid profile in POI patients and control subjects with normal menstrual cycles. A total of 43 patients with nondiabetic POI were studied in order to evaluate and compare the findings with those of the control group, which comprised 33 women with normal menstrual cycles. The women with POI had higher levels of serum copper, serum insulin, glucose, LDL-cholesterol, total cholesterol, HOMA-IR, hs-CRP, and procalcitonin, whereas serum vitamin D and zinc levels were lower compared with the healthy control group. Follicle-stimulating hormone (FSH) levels were positively correlated with insulin, glucose, HOMA-IR, hs-CRP, procalcitonin, and copper and negatively correlated with vitamin D and zinc levels. In multivariate statistic analyses with body mass index and FSH as dependent variables, FSH was positively associated with copper and HOMA-IR negatively with vitamin D levels. The present study demonstrated that women with POI have traditional risk factors for diabetes mellitus, including lower levels of vitamin D, whereas higher levels of copper and HOMA-IR.

    The premutation state of FMR1 (Fragile X Mental Retardation 1) has been associated with primary ovarian insufficiency (POI), and is the most common known genetic cause for 46,XX patients. Nevertheless, very few studies have analyzed its frequency in Latin American populations. Additionally, a relationship between alleles carrying a cryptic microdeletion in the 5’UTR of FMR2 and the onset of POI has only been studied in one population. Our aim was to analyze the incidence of FMR1 premutations and putative microdeletions in exon 1 of FMR2 in a cohort of Argentinean women with POI. We studied 133 patients and 84 controls. Fluorescent PCR was performed, and the FMR2 exon 1 was further sequenced in samples presenting less than 11 repeats. We found the frequency of FMR1 premutations to be 6.7% and 2.9% for familial and sporadic patients, respectively. Among controls, 1/84 women presented a premutation. In addition, although we did not find microdeletions in FMR2, we observed a change (T >C) adjacent to the repeats in two sisters with POI. Given the repetitive nature of the sequence involved, we could not ascertain whether this represents a single nucleotide polymorphism (SNP) or a deletion. Therefore, a relationship between FMR2 and POI could not be established for our population. PMID:28812997

    This report is an integrated study to include the molecular simulation, physicochemical characterization and biological analysis of a paclitaxel-loaded PHBV nanoparticle that demonstrates uptake, release and cytotoxicity in cancer cell lines. Taking this nanoparticle one step closer to its use in a clinical setting, we demonstrate that it causes significant cell death in primary cultures of stage IIIc serous ovarian cancer cells isolated from six patients. Molecular simulations revealed a high affinity of paclitaxel for the water-polymer interface, thus the drug is delivered only when the polymer near it is degraded. The Fourier transform infrared spectroscopy suggests the formation of a short-lived crystalline phase, also observed in the CG simulations, and transmission electron microscopy revealed branched structures on the surface of particles, which disappeared after 4 days. Biological analyses indicated that these particles have a 48-h window of toxicity protection, allowing for the endocytosis of the particle by the cells; this finding was corroborated by confocal microscopy and flow cytometry. The low cost to synthesize PHBV using microorganisms and the potential chemical modifications of the polymer make it attractive for inexpensive, large-scale pharmaceutical production.

  7. A link between human papilloma virus vaccination and primary ovarian insufficiency: current analysis.

    The cause of primary ovarian insufficiency (POI) is multifactorial. Known causes include external factors such as chemotherapy, radiotherapy, exposure to endocrine-disrupting chemicals, infections that lead to a permanent insult to the ovary, autoimmune conditions, and genetic causes. An association between the quadrivalent antihuman papilloma vaccine (HPV4) and POI was recently suggested. An increasing number of cases of POI post-HPV4 are being reported. Possible mechanisms for the suspected effect of HPV on female reproductive function are a toxic effect or an autoimmune response. The trigger could be the vaccine immunogen contents or the adjuvants, the latter are used to increase the immune reaction. The adjuvant in HPV4 contains aluminum. Animal models have shown aluminum exposure to inhibit expression of female reproductive hormones and to induce histologic changes in the ovaries. Specific genetic compositions may be more susceptible to developing an autoinflammatory syndrome after exposure to an environmental factor. The mechanisms responsible for POI are not yet fully understood. Although case reports cannot establish causation, awareness of a possible link between HPV4 and POI will help to identify and manage future cases that may arise.

    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

    Bevacizumab was recently approved by the US Food and Drug Administration for use in recurrent platinum resistant epithelial ovarian cancer (EOC), fallopian tube cancer (FTC), or primary peritoneal cancer (PPC) when no more than two prior cytotoxic regimens have been used; due to concerns for gastrointestinal perforation. We sought to determine bevacizumab-related toxicities in heavily pretreated recurrent EOC. We performed a retrospective chart review of patients with recurrent EOC, FTC, and PPC from 2001 to 2011. Patients who received at least two prior chemotherapy regimens before bevacizumab were included. Medical records were reviewed for bevacizumab associated toxicities. The Wilcoxon-Mann-Whitney test was used to compare quantitative variables. Survival was estimated with the Kaplan-Meier method. Sixty patients met inclusion criteria. At the start of bevacizumab treatment, the median age was 60 years and the median body mass index was 26.5 kg/m². More than 50% of patients received bevacizumab after three prior cytotoxic regimens. Grade 3 or higher bevacizumab associated toxicity events occurred in four patients, including one patient who developed a rectovaginal fistula. The median overall survival from the start of bevacizumab treatment was 21.05 months (95% CI, 18.23 to 32.67; range, 1.9 to 110 months). The number of cytotoxic regimens prior to bevacizumab treatment did not differ in those that experienced a toxicity versus those that did not (p=0.66). The use of bevacizumab in heavily pretreated EOC, FTC, or PPC is worth consideration.

    Background To identify patients at risk for postoperative morbidities, we evaluated indications and factors associated with 30-day readmission after epithelial ovarian cancer surgery. Methods Patients undergoing primary surgery for epithelial ovarian cancer between January 2, 2003, and December 29, 2008, were evaluated. Univariable and multivariable logistic regression models were fit to identify factors associated with 30-day readmission. A parsimonious multivariable model was identified using backward and stepwise variable selection. Results In total, 324 (60.2%) patients were stage III and 91 (16.9%) were stage IV. Of all 538 eligible patients, 104 (19.3%) were readmitted within 30 days. Cytoreduction to no residual disease was achieved in 300 (55.8%) patients, and 167 (31.0%) had measurable disease (≤1 cm residual disease). The most common indications for readmission were surgical site infection (SSI; 21.2%), pleural effusion/ascites management (14.4%), and thromboembolic events (12.5%). Multivariate analysis identified American Society of Anesthesiologists score of 3 or higher (odds ratio, 1.85; 95% confidence interval, 1.18–2.89; P = 0.007), ascites [1.76 (1.11–2.81); P = 0.02], and postoperative complications during initial admission [grade 3–5 vs none, 2.47 (1.19–5.16); grade 1 vs none, 2.19 (0.98–4.85); grade 2 vs none, 1.28 (0.74–2.21); P = 0.048] to be independently associated with 30-day readmission (c-index = 0.625). Chronic obstructive pulmonary disease was the sole predictor of readmission for SSI (odds ratio, 3.92; 95% confidence interval, 1.07–4.33; P = 0.04). Conclusions Clinically significant risk factors for 30-day readmission include American Society of Anesthesiologists score of 3 or higher, ascites and postoperative complications at initial admission. The SSI and pleural effusions/ascites are common indications for readmission. Systems can be developed to predict patients needing outpatient management, improve care, and reduce

    Primary osteosarcoma of the bone with rhabdoid features is a rare malignant tumor of bone, not previously described in the literature. Here we report a 69-year-old female who originally presented with a right femur pathologic fracture. Radiographs of the injury showed an aggressive-appearing lesion of the distal femur. Initial biopsy was done, which was not diagnostic; additional advanced imaging studies were performed, which failed to show any other site within the body with detectable disease process. Accordingly, the patient underwent radical resection of the distal femur and reconstruction with endoprosthesis. Histopathology obtained from the operative specimen showed osteosarcoma with rhabdoid features. Two months after surgery, the patient is symptom-free and doing well; she is currently pending adjuvant chemotherapy. Although rhabdoid features have been described in extraskeletal osteosarcoma, this appears to be the first mention of osteosarcoma of bone with rhabdoid features in the literature. PMID:28058126

    Lenalidomide has been linked to second primary malignancies in myeloma. We aimed to pool and analyse available data to compare the incidence of second primary malignancies in patients with and without lenalidomide exposure. We identified relevant studies through a search of PubMed and abstracts from the American Society of Clinical Oncology, American Society of Hematology, and the International Myeloma Workshop. Randomised, controlled, phase 3 trials that recruited patients with newly diagnosed multiple myeloma between Jan 1, 2000, and Dec 15, 2012, and in which at least one group received lenalidomide were eligible for inclusion. We obtained individual patient data (age, sex, date of diagnosis, allocated treatment and received treatment, duration of treatment and cause of discontinuation, maintenance treatment, date of first relapse, date of second primary malignancy diagnosis, type of second primary malignancy, date of death or last contact, and cause of death) by direct collaboration with the principal investigators of eligible trials. Primary outcomes of interest were cumulative incidence of all second primary malignancies, solid second primary malignancies, and haematological second primary malignancies, and were analysed by a one-step meta-analysis. We found nine eligible trials, of which seven had available data for 3254 patients. 3218 of these patients received treatment (2620 had received lenalidomide and 598 had not), and were included in our analyses. Cumulative incidences of all second primary malignancies at 5 years were 6·9% (95% CI 5·3-8·5) in patients who received lenalidomide and 4·8% (2·0-7·6) in those who did not (hazard ratio [HR] 1·55 [95% CI 1·03-2·34]; p=0·037). Cumulative 5-year incidences of solid second primary malignancies were 3·8% (95% CI 2·7-4·9) in patients who received lenalidomide and 3·4% (1·6-5·2) in those that did not (HR 1·1 [95% CI 0·62-2·00]; p=0·72), and of haematological second primary malignancies were 3

    Peritoneal ascites are a distinguishable feature of patients with advanced epithelial ovarian cancer (EOC). The presence of different lymphocyte subsets has been reported in EOC-associated ascites, which also can or not contain malignant cells. The goal of this study was to analyze the functional characteristics of natural killer (NK) cells from EOC-associated ascites in terms of their expression of activating receptors and ascites’ contents of lymphocyte subtypes, cytokine profile and presence of EOC cells. NK cell function was evaluated by the expression of the degranulation marker CD107a in resting and interleukin (IL)-2 stimulated NK cells from ascites and blood. Degranulation of NK cells from EOC cell-free ascites was significantly (p < 0.05) higher than all the other groups, either in their resting state or after IL-2 stimulation, suggesting a previous local stimulation. In contrast, treatment with IL-2 had no effect on NK cells from ascites with EOC cells. The amount of regulatory T cells was significantly higher in ascites with EOC cells compared to EOC cell-free ascites. Ascites with EOC cells also had higher levels of tumor necrosis factor (TNF)-α, suggesting inflammation related to the malignancy. In conclusion, the functional performance of NK cells was distinct between EOC cell-free ascites and ascites with EOC cells. The impairment of NK cell response to IL-2 in ascites with EOC cells was consistent with an immunosuppressive tumor microenvironment. PMID:28513532

    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, since 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. PMID:27259061

    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.

    (1)H-MRS was performed on 12 women (age range 45-72) with ovarian cancer of FIGO stage 3 or above using a 3T MRI system with an 8-channel cardiac receive coil. Respiratory-triggered PRESS-localized spectra (TE = 144 ms) were obtained separately from an ovarian mass and from metastatic disease. Peak areas were quantified relative to unsuppressed water using LCModel and spectra were discarded if LCModel reported signal-to-noise ratio (SNR) < 3 or if no metabolites were reported with standard deviation (SD) < 30%. The cystic fraction of each voxel was estimated by thresholding T(2)-weighted images, and this was used both to correct the reported metabolite concentrations and to calculate an expected SNR of choline using the measured SNR of water. Choline was detected in 10/12 primary tumors and 5/11 metastatic lesions (range 2.0-16.6 mM). Of the 8/23 failures, 7 had a predicted choline SNR < 2, confirming that the failure to detect choline could be explained by technical problems. Glycine was observed in one benign lesion. (1)H-MRS can be used to quantify choline in primary and metastatic masses in ovarian cancer, but the moderately high rate of failure to detect choline necessitates careful recording of data quality parameters to discriminate true from false negatives.

    Background Currently, no specific immunohistochemical markers are available to differentiate primary mucinous epithelial ovarian cancer (MOC) from adenocarcinomas originating at other sites that have metastasised to the ovary, which may have an impact on patient management and prognosis. Aim To investigate the expression of two intestinal markers, galectin 4 and meprin α, in mucinous carcinomas of the ovary and gastrointestinal tract. Methods Using immunohistochemical analysis, the expression of galectin 4 and meprin α was investigated in 10 MOCs and in 38 mucinous adenocarcinomas of colon, pancreas, stomach and appendix, the most common sites of origin of ovarian metastases. Results Total cytoplasmic galectin 4 expression was relatively consistent between the different carcinomas. Membranous meprin α expression was significantly lower in MOCs compared with gastrointestinal carcinomas. Moreover, meprin α expression showed greater discrimination between the ovarian and gastrointestinal carcinomas than the cytokeratins CK7 and CK20, the current standard immunohistochemical markers used to determine the tissue origin of mucinous carcinomas involving the ovaries. Conclusions Meprin α is a useful additional marker in differentiating primary from secondary mucinous adenocarcinomas of the ovary. PMID:16822880

    Most ovarian tumors are cystic structures containing variable amounts of fluid. Several studies of ovarian cyst fluid focus on one specific metabolite using conventional assay systems. We examined the potential of (1)H-nuclear magnetic resonance spectroscopy in evaluation of the overall metabolic composition of cyst fluid from different ovarian tumors. Ovarian cyst fluid samples obtained from 40 patients with a primary ovarian tumor (12 malignant and 28 benign) were examined. After deproteinization and pD standardization, we performed (1)H-NMR spectroscopy on a 600 MHz instrument. With (1)H-NMR spectroscopy we found detectable concentrations of 36 metabolites with high intersample variation. A number of unassigned resonances as well as unexpected metabolites were found. We introduce an overall inventory of the low-molecular-weight metabolites in ovarian cyst fluid with corresponding resonances. Significant differences in concentration (p < 0.01) were found for several metabolites (including an unknown metabolite) between malignant and benign ovarian cysts. Furthermore, higher concentrations in malignant- and lower in benign fluids were found compared to normal serum values, indicating local cyst wall metabolic processes in case of malignant transformation. We conclude that (1)H-nuclear magnetic resonance spectroscopy can give an overview of low-molecular-weight proton-containing metabolities present in ovarian cyst fluid samples. The metabolic composition of cyst fluid differs significantly between benign and malignant ovarian tumors. Furthermore, differences between benign subgroups possibly related to histopathological behaviour can be detected. The presence of N-acetyl aspartic acid and 5-oxoproline exclusively in serous cystadenoma samples is remarkable. Future studies will concentrate on these findings and explore the possibilities of extrapolating information from the in vitro studies to in vivo practice, in which metabolic differences between malignant and

    We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of uniform oval to cuboidal cells encompassing numerous blood vessels. Immunohistochemically, the tumor cells exhibited smooth muscle markers, but were negative for neuroendocrine markers. The diagnosis of primary pulmonary glomus tumor was therefore made. Subsequent bronchoscopic intervention allowed us to pin-point the origin of the tumor: superior segmental B(6a/b). She underwent a left lower lobe superior segmental resection successfully. Glomus tumors are relatively rare soft tissue tumors, and those of bronchopulmonary origin are exceedingly rare clinical condition. Among primary lung tumors, the carcinoid tumor is a mimic of the glomus tumor, and differentiating these tumors is known to be difficult, especially using small biopsy samples. In the present case, a large tissue sample obtained by bronchoscopic snaring was quite useful for the correct preoperative diagnosis. Because of the disease rarity, malignancy grade estimation of visceral glomus tumors has not been clearly addressed. Recently, the histopathological diagnostic criteria for malignant glomus tumors was defined in the WHO classification of soft tissue and bone tumors 4th edition. Here we also reviewed the literature on primary bronchopulmonary glomus tumors with special attention to the current concept of malignancy grade estimation.

    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.

    To analyze the clinicopathological factors that affect the prognosis and fertility of patients with malignant ovarian germ cell tumors (MOGCTs). The medical records and follow-up data of 106 patients with MOGCTs who were treated at The Affiliated Tumor Hospital of Guangxi Medical University between January 1986 and December 2010 were enrolled in this study. A Kaplan-Meier analysis was used to analyze the survival curves. The different prognoses among the various clinicopathological factors were evaluated using a univariate analysis and a log-rank test. The multivariate analysis was performed using the Cox proportional hazard regression method. A logistic regression analysis was used to evaluate the influence of different factors on the prognoses and fertility. The median age at primary treatment was 22 years (range: 9-61years). A total of 59 patients received fertility-preserving surgery, 45 received radical surgery and 94 received postoperative adjuvant chemotherapy. The median follow-up time was 56.5 months (range: 2-309 months). A total of 11 patients experienced a recurrence, and 23 patients died from their cancer. Of the 47 patients who are alive without tumor, 45 have normal menstruation. Of the 39 patients who wished to become pregnant, 31 patients had 33 successful pregnancies that resulted in 33 live births. No statistically significant difference (p > 0.05) was observed with respect to the progression-free survival (PFS; 67.6 vs. 63.3%), the overall survival (OS; 70 vs. 64.1%) and the mortality rate (15.3 vs. 31.3%) between patients who received fertility-preserving surgery and those who received radical surgery. The univariate analysis showed that the pathological types, postoperative residual tumor size, lymph node resection, and omental resection were associated with OS (p < 0.1), whereas postoperative residual tumor size, number of chemotherapy cycles, lymph node resection, and omental resection were associated with PFS (p < 0.1).

    A rare variant of malignant melanoma (MM) of the uterine cervix that mimics a malignant peripheral nerve sheath tumor (MPNST) is described. A 43-year-old white woman was admitted to the hospital complaining of genital discharge and vaginal bleeding. Neoadjuvant chemotherapy and total abdominal hysterectomy and bilateral salpingo-ovariectomy plus pelvic lymphadenectomy were performed, and the diagnosis was MPNST, FIGO IIB. Pathological examination showed a diffuse proliferation of amelanotic spindle cells and large, highly atypical, frequently multinucleated, bizarre, and S100-, HMB-45-, vimentin-positive cells. The patient remained disease-free for 43 months, when an abdominal computed tomographic scan showed local polypoid vaginal lesions, with histological features of typical MM. A pathological review was obtained in our institution by a gynecological pathologist, who defined the primary neoplasm in the cervix as an MM, with a pattern of growth histologically simulating an MPNST, metastatic to the vagina. To our knowledge, this is the first report in literature of MM of the uterine cervix resembling MPNST. Despite its rarity, this variant of MM should be considered when a diagnosis of cervix MPNST is made. The histological and immunohistochemical features of these different entities should be considered in the differential diagnosis.

    A study was conducted to investigate secondary malignant neoplasm (SMN) occurrence following radiotherapy (RT) for cancer in children and young adults, to examine the spatial distribution of SMNs in relation to the irradiated field, and to evaluate a possible role of bystander effects in SMN distribution. Forty-two SMNs were identified among 7257 subjects diagnosed with cancer while living in Yorkshire, UK. Thirty-two of these occurred in patients receiving RT. Distances between SMN locations and RT field edge were estimated along with dose at SMN site. Expected radiation-induced SMN frequency in remote tissues receiving less than 0.1 Gy was predicted using risk estimates based on atomic bombing data. After a median follow-up period of 7.58 years, patients treated with RT were at a nearly five-fold increased risk of developing a subsequent primary neoplasm than the general population in the 0-29 years age range. The most common type of secondary malignancy associated with RT was of the central nervous system (28%), followed by sarcoma (25%) and leukemia (19%). Considering only solid SMNs developing 5 years or more from treatment, the spatial distribution showed a strong pattern of proximity to the irradiated field, with 68% occurring in-field or within 8 cm of the field edge. The SMN frequency in distant tissues receiving doses of less than 0.1 Gy was low but compatible with local absorbed dose.

    Pertuzumab is a humanized monoclonal antibody that inhibits human epidermal growth factor receptor 2 (HER2) heterodimerization and has single-agent activity in recurrent epithelial ovarian cancer. The primary objective of this phase II study was to characterize the safety and estimate progression-free survival (PFS) of pertuzumab with gemcitabine in patients with platinum-resistant ovarian cancer. Patients with advanced, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who had received a maximum of one prior treatment for recurrent cancer were randomly assigned to gemcitabine plus either pertuzumab or placebo. Collection of archival tissue was mandatory to permit exploration of biomarkers that would predict benefit from pertuzumab in this setting. One hundred thirty patients (65 per arm) were treated. Baseline characteristics were similar between arms. The adjusted hazard ratio (HR) for PFS was 0.66 (95% CI, 0.43 to 1.03; P = .07) in favor of gemcitabine + pertuzumab. The objective response rate was 13.8% in patients who received gemcitabine + pertuzumab compared with 4.6% in patients who received gemcitabine + placebo. In patients whose tumors had low HER3 mRNA expression (< median, n = 61), an increased treatment benefit was observed in the gemcitabine + pertuzumab arm compared with the gemcitabine alone arm (PFS HR = 0.32; 95% CI, 0.17 to 0.59; P = .0002). Grade 3 to 4 neutropenia, diarrhea, and back pain were increased in patients treated with gemcitabine + pertuzumab. Symptomatic congestive heart failure was reported in one patient in the gemcitabine + pertuzumab arm. Pertuzumab may add activity to gemcitabine for the treatment of platinum-resistant ovarian cancer. Low HER3 mRNA expression may predict pertuzumab clinical benefit and be a valuable prognostic marker.

    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.

    Use of interstitial radiation holds promise in the treatment of primary malignant brain tumors, but optimal technical factors have yet to be determined. We have developed a method of precise CT directed stereotactic placement of radioactive sources in a predetermined target volume. We use low activity (1-2 millicurie/speed) sources of SVI loaded in silastic catheters, which are positioned in a parallel array in the target. Positioning of such multiple sources toward the periphery of the volume enhances achievable dose homogeneity. Seeds of various activities can be differentially loaded into each catheter and the catheters can be positioned at various radii from the central target so that the treated volume corresponds to the identified (often irregular) target volume. Although the implant is designed to be permanent, the sources can be removed easily in a second procedure.

    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

    Objective Bevacizumab was recently approved by the US Food and Drug Administration for use in recurrent platinum resistant epithelial ovarian cancer (EOC), fallopian tube cancer (FTC), or primary peritoneal cancer (PPC) when no more than two prior cytotoxic regimens have been used; due to concerns for gastrointestinal perforation. We sought to determine bevacizumab-related toxicities in heavily pretreated recurrent EOC. Methods We performed a retrospective chart review of patients with recurrent EOC, FTC, and PPC from 2001 to 2011. Patients who received at least two prior chemotherapy regimens before bevacizumab were included. Medical records were reviewed for bevacizumab associated toxicities. The Wilcoxon-Mann-Whitney test was used to compare quantitative variables. Survival was estimated with the Kaplan-Meier method. Results Sixty patients met inclusion criteria. At the start of bevacizumab treatment, the median age was 60 years and the median body mass index was 26.5 kg/m2. More than 50% of patients received bevacizumab after three prior cytotoxic regimens. Grade 3 or higher bevacizumab associated toxicity events occurred in four patients, including one patient who developed a rectovaginal fistula. The median overall survival from the start of bevacizumab treatment was 21.05 months (95% CI, 18.23 to 32.67; range, 1.9 to 110 months). The number of cytotoxic regimens prior to bevacizumab treatment did not differ in those that experienced a toxicity versus those that did not (p=0.66). Conclusion The use of bevacizumab in heavily pretreated EOC, FTC, or PPC is worth consideration. PMID:27329195

    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

    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

    Hepatocellular carcinoma and intrahepatic cholangiocarcinoma 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 after genetic manipulation of Yes-associated protein, a transcription coactivator. Here, we comprehensively documented Yes-associated protein expression in the human liver and primary liver cancers. We showed that nuclear Yes-associated protein expression is significantly increased in human intrahepatic cholangiocarcinoma and hepatocellular carcinoma. We found that increased Yes-associated protein levels in hepatocellular carcinoma are due to multiple mechanisms including gene amplification and transcriptional and posttranscriptional regulation. Survivin, a member of the inhibitors-of-apoptosis protein family, has been reported as an independent prognostic factor for poor survival in both hepatocellular carcinoma and intrahepatic cholangiocarcinoma. We found that nuclear Yes-associated protein expression correlates significantly with nuclear Survivin expression for both intrahepatic cholangiocarcinoma and hepatocellular carcinoma. Furthermore, using mice engineered to conditionally overexpress Yes-associated protein in the liver, we found that Survivin messenger RNA expression depends upon Yes-associated protein levels. Our findings suggested that Yes-associated protein contributes to primary liver tumorigenesis and likely mediates its oncogenic effects through modulating Survivin expression.

    Alkaline Phosphatase (APase) activity has been shown to be enhanced specifically in mitogen stimulated B lymphocytes committed to proliferation, but not in T lymphocytes. APase gene expression was analyzed in proliferating murine and human primary lymphocytes and human malignant cell lines using reverse transcriptase and real time PCR. In mitogen stimulated murine splenic lymphocytes, enhancement of APase activity correlated well with an increase in APase gene expression. However, in mitogen stimulated murine T lymphocytes and human PBL despite a vigorous proliferative response, no increase in APase enzyme activity or gene expression was observed. A constitutive expression of APase activity concomitant with APase gene expression was observed inhuman myeloma cell line, U266 B1. However, neither enzyme activity nor gene expression of APase were observed in human T cell lymphoma, SUPT-1. The results suggest a differential expression of APase activity and its gene in proliferating primary lymphocytes of mice and humans. The specific expression of APase activity and its gene only in human myeloma cells, but not in proliferating primary B cells can be exploited as a sensitive disease marker.

    A 58-year-old Japanese male patient visited our hospital for evaluation of an elastic hard mass, measuring 80 x 50 mm, in the right axillary area. Incisional biopsy for suspected malignancy was performed, and histopathologic examination by hematoxylin-eosin (H&E) staining yielded a diagnosis of poorly differentiated adenocarcinoma metastatic from an unknown primary. As the tumor was immunohistochemically positive for both ER and PgR, metastatic breast cancer was strongly suspected. Ultrasonography, CT, and MRI revealed no evidence of tumors in the bilateral mammary glands. Detailed examination of the head and neck region, lung, and upper and lower gastrointestinal tract also revealed no evidence of a primary tumor. After chemotherapy, the patient underwent tumor resection with axillary lymph node dissection. On the basis of the histological features of H&E-stained specimens and immunohistochemistry of the resected tumor, this case was diagnosed as breast cancer of unknown origin in a male. The tumor could have been an axillary lymph node metastasis from an occult breast carcinoma, or primary cancer arising in an accessory mammary gland.

    Background Many patients with primary liver cancers are not candidates for surgery, and systemic therapies are seldom effective. Selective internal radiation therapy (SIRT) has been shown to obtain partial and even complete response in unresectable primary tumors. As a “side effect”, SIRT can induce contra-lateral liver hypertrophy. Tumor response to SIRT can be sufficient to allow disengagement from normal vital structures whose involvement is the cause of the initial unresectability. The contra-lateral hypertrophy can thereby increase the future liver remnant (FLR) volume to over the safe threshold so that extended hepatectomy can be performed. Summary A review of the available literature was performed to assess the tumor response and liver hypertrophy that can be expected after SIRT, in order to delineate whether SIRTcan play a role in conversion therapy for resectability of primary liver malignancies. Key Message Available data suggest that SIRT in unresectable hepatocellular and cholangiocellular carcinomas can provide a considerable down-sizing of the tumors to possibly allow resection. Hypertrophy of the contra-lateral lobe represents a favorable collateral effect that can help in achieving safer subsequent major hepatectomy. In patients whose FLR volume represents the only surgical concern, portal vein embolization remains the treatment of choice. PMID:27781202

    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

    BACKGROUND The forkhead transcription factor Foxo3 is a master regulator and potent suppressor of primordial follicle activation. Loss of Foxo3 function in the mouse leads to premature ovarian failure due to global follicle activation. Here we show that the mouse Foxo3 locus is haploinsufficient, and that Foxo3−/+ females undergo early reproductive senescence consistent with an increased rate of primordial follicle utilization. Then, to determine if heterozygous or homozygous polymorphisms or mutations of the human orthologue FOXO3 contribute to premature ovarian failure (POF) or idiopathic primary amenorrhea (PA), we sequenced the exons and flanking splice sequences of the gene in a large number of women with idiopathic POF (N=273) or PA (N=29). A total of 8 single nucleotide polymorphisms (SNPs) were identified, revealing a substantial amount of genetic variation at this locus. Allelic frequencies in control samples excluded several of these variants as causal. For the remaining variants, site-directed mutagenesis was performed to assess their functional impact. These rare sequence variants were not associated with significant decreases in FOXO3 activity. CONCLUSIONS Taken together, our findings suggest that, despite the potential for FOXO3 haploinsufficiency to cause ovarian failure, FOXO3 mutations or common SNPs are not a common cause of either POF or PA.

    Infertility is a medical and psychosocial problem with a high prevalence. There are different treatments for this problem in Iranian traditional medicine. A 28-year-old woman presented with the complaints of 4 emergency operations of the left ovarian cyst during 4 years and infertility. Diagnostic laparoscopy showed an ovarian cyst, adhesion, and endometriosis. Hysteroscopy was unremarkable. After 2 months of letrozole administration, the ovarian cyst ruptured again. Considering the failure of conventional treatments, Iranian traditional medicine products were administered to the patient. After 3 months, the patient conceived and delivered a healthy boy through normal vaginal delivery. These compounds may help with pregnancy as a uterine tonic, vitalizer, and aphrodisiac with brain and cardiac tonic properties.

    Low skeletal muscle mass (sarcopenia) has been reported to have an influence on survival and toxicities of chemotherapy in several solid tumors. The impact of sarcopenia on the treatment of ovarian cancers has not been determined. The present study aimed to evaluate correlation between sarcopenia and toxicities of chemotherapy in ovarian cancers. Medical charts of the ovarian cancer patients that received chemotherapy with paclitaxel and carboplatin at our hospital between 2010 and 2015 were retrospectively reviewed. Muscle areas of bilateral psoas major muscles at the fifth lumbar vertebra were measured using images obtained by computed tomography. The volume of muscle and clinicopathological factors were evaluated for toxicities of chemotherapy. The protocol of the present study was approved by the institutional review board of our institution. A total of 76 patients with ovarian cancers were identified, and enrolled in the present study. Median psoas index (PI, the psoas muscle major cross-sectional area divided by the height squared) was 583 mm(2)/m(2) (range 326-999). The patients with low PI developed peripheral neuropathy more frequently compared with those with high PI (32 vs. 11%; P = 0.047). PI value was not associated with other toxicities such as neutropenia and thrombocytopenia. PI value was associated with grade 2 or higher peripheral neuropathy in univariate analysis (OR = 3.92; 95% CI 1.21-15.32; P = 0.02) and multivariate analysis (OR = 3.93; 95% CI 1.17-15.87; P = 0.03). PI value was significantly associated with peripheral neuropathy induced by combination therapy with paclitaxel and carboplatin in ovarian cancer patients. Although further studies are needed to confirm the results, the volume of skeletal muscle mass could be a potential biomarker to predict toxicities in ovarian cancer patients.

    Ovarian sarcomas represent less than 1% of all ovary cancers and usually are frequent in adults. Primary angiosarcomas are exceptional in the ovaries within children. We reported a case of primary ovarian angiosarcoma in a 12-year-old girl in a resource-constrained context. Immunohistochemistry study showed the positivity of CD34, CD31, factor VIII, while S100 was negative. The diagnosis of primary non-metastatic angiosarcoma was retained. She was unable to undergo the CWS-2002P chemotherapy since her parents could not afford it. This case report described a rare type of a primary ovarian angiosarcoma within a child, diagnosed in a low-income country in a laboratory with limited resources.

    The antioxidant enzymes catalase, glutathione reductase (GR), glutathione S-transferase (GST), glutathione peroxidase (GPx), and superoxide dismutase (SOD) were determined in the androgen-response LNCaP and androgen-nonresponsive PC-3 and DU 145 cells as well as in prostatic epithelial cell cultures of benign and malignant human prostatic tissue. There were no differences between the enzyme activities of the human primary cell cultures from cancerous tissue and their normal counterparts. The enzyme activities of the three permanent cell lines were either higher (SOD, catalase, GR) or lower (GST, GPx) than in the primary cell cultures. In LNCaP cells catalase and GR were significantly higher, GST, in contrast, was significantly lower than in PC-3 and DU 145 cells. GST in PC-3 and DU 145 cells, and SOD in all the three cell lines showed no significant differences. Catalase, GPx and GR values were significantly different in the three permanent cell lines. The different enzymatic equipment of the prostate cancer cell lines provides the basis for experimental testing of new concepts of cancer treatment with the help of systematic modulations of the antioxidant defence systems in prostate cancer.

    Primary melanomas of the uterine cervix are rare tumors with no more than 60 cases reported in the world literature. Poor prognosis is considered for the neoplasia itself as well as for diagnostic tardiness. There is no standard treatment; however, radical surgery is the treatment cornerstone. Our aim was to present the case of a 34-year-old woman with a primary malignant melanoma in the uterine cervix with affectation of the posterior face of the vagina without metastasis. Total infraelevator pelvic exenteration and adjuvant radiotherapy was performed. The patient was under surveillance for 8 years of followup without evidence of local or distant disease. The majority of case reports found suggests radical hysterectomy as the treatment indicated for these patients. Notwithstanding this, survival is very short when patients are treated in this manner. Based on our results and on those reported in the literature, we propose initial treatment with total pelvic exenteration as optimal management for this neoplasia in its initial form.

    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.

    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.

    The occurrence of multiple primary malignancies (MPM) in one patient is a rare but increasingly frequent event, partly due to medical advances in diagnosis and therapy. A number of theories have been proposed to explain MPM, but none have been proven. A key risk factor appears to be family history. We present the case of a 43-year-old male with multiple cancers who was first admitted to the hospital for an undifferentiated pleomorphic sarcoma/pleomorphic malignant fibrous histiocytoma (pG2T2bN0Mx stage III) of the right scapula in May 2009. The patient underwent three tumor resections in situ due to tumor recurrence. During the period of chemotherapy and radiotherapy, computed tomography (CT) revealed a 10x10-cm enhancing soft mass of the ascending colon, which was diagnosed as mucinous adenocarcinoma in a pathological report. Laboratory data showed elevated serum levels of carcinoembryonic antigen (CEA, 20.0 μg/l; normal range, 0.0-10.0 μg/l). Certain family members of the patient had been diagnosed with endometrial, colon and pancreatic cancer. None of the family had a smoking history or presented with familial adenomatous polyposis (FAP). The patient with hereditary non-polyposis colorectal cancer (HNPCC), whose family fulfilled Amsterdam Criteria I (AC I), has remained free of disease for 15 months. Family history may be a key risk factor for MPM and HNPCC, the detailed molecular mechanisms of which remain to be elucidated. This case report with an investigation of family history may improve the clinical recognition of HNPCC and MPM.

    It is known that hypophysial gonadotropins circulate in different molecular forms which are provided with different biological activity and that the proportion of such varieties keep a relation with the concentrations of estrogens in circulation. In physiological menopause predominate the great molecular forms which have a lesser biological activity and when estrogens are administrated a change is produced to smaller molecular forms. The present study tries to determine if in cases of ovarian insufficiency of long duration as in precocious menopause and the syndrome of refractory ovary the chromatographic conduct of gonadotropin is similar. Six patients with precocious menopause, and three with the syndrome of refractory ovary, were studied, in order to make a comparison of chromatographic pattern of FSF and LH in serum, with the one found in women with normal ovarian function and with physiologic menopause. The chromatographic analysis was done by filtration in gel of the serum and the subsequent determination of LH and FSH by RIA of double antibody. It was found that the chromatographic pattern of patients with ovarian insufficiency of long duration, characteristically presents larger molecular forms, specially in the refractory ovary syndrome with a greater alteration in the profile of LH. With base on these results it is concluded that the duration of ovarian insufficiency determine the type of molecular form, predominant, of gonadotropins. Also it is suggested that for the syndrome of refractory ovary, the greater heterogenicity of gonadotropins may explain part of physiopathogeny.

    BRAFV600E mutations are present in approximately 50% of cutaneous malignant melanomas (CMMs). The use of BRAFV600E mutation-specific monoclonal antibody VE1 immunohistochemical analysis may facilitate rapid detection of BRAFV600E mutations in CMMs and demonstrate heterogeneity among tumors. To characterize the pattern of BRAFV600E protein expression in primary CMMs with matched metastases and to analyze the use of VE1 immunohistochemical analysis in clinical practice using formalin-fixed, paraffin-embedded tumor tissue. In this retrospective cohort study performed at Karolinska University Hospital from September 2012 to September 2013, we examined CMMs (124 primary tumors and 76 metastases) with VE1 immunohistochemical analysis, and results were compared with DNA mutation analyses. Determination of intratumoral and intertumoral heterogeneity as well as the sensitivity and specificity of VE1 immunohistochemical analysis. Positive staining results with the VE1 antibody were detected in 94 of 200 tumors (47.0%). In general, VE1 staining was homogeneous. However, VE1 staining intensity varied among the primary tumors and corresponding metastases in 63 of 135 tumors (46.7%), but a change of mutational status based on DNA analysis was found in only 4 matched tumors (3.0%). Discordant findings between DNA mutation analysis and immunohistochemical analysis were observed in 12 tumors. The overall sensitivity and specificity of VE1 immunohistochemical analysis were 96.7% and 94.5%, respectively. A comparable sensitivity was obtained for primary and metastatic CMMs. The specificity was lower among primary CMMs (92.4%) compared with metastases (98.0%). We found VE1 immunohistochemical analysis to be a useful and rapid assay for BRAFV600E mutations that may contribute to the detection of intratumoral and intertumoral heterogenetic subclones. Tumors with positive results, including strong staining, should be expedited for confirmatory BRAF mutation testing. If this test result

    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

    To evaluate the efficacy of topoisomerase I inhibitor, topotecan, in patients with recurrent BRCA+ versus BRCA- ovarian, fallopian tube, and primary peritoneal carcinomas. A single-institution retrospective analysis of platinum-resistant patients characterized for the presence or absence of known deleterious BRCA mutations. Patients received topotecan at a dose and schedule determined by their treating physician (five day or weekly). Response rate and progression-free survival (PFS) were assessed. A total of 50 patients (9 BRCA+, 41 BRCA-) were treated with topotecan. Both groups were well balanced in terms of age, stage, grade, and number of prior therapies. All patients had high-grade serous carcinoma. The clinical benefit rate in BRCA+ and BRCA- patients was 0% and 26.8% (6 PRs, 6 SDs), respectively (p=0.18). Median PFS in BRCA+ and BRCA- pts was 1.7 months (95% CI: 1.0-2.8 months) and 2.5 months (95%CI: 1.9-2.8 months), respectively (p=0.057). Median time to best response was 1.9 months, and median response duration 2.6 months. This analysis in a heavily pretreated cohort of patients fails to support the superiority of topotecan in BRCA+ platinum-resistant ovarian, fallopian tube, and primary peritoneal cancers. Further study of this class of agents, specifically in less heavily-pretreated patients, may still be warranted. Copyright © 2011 Elsevier Inc. All rights reserved.

    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

    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

    Purpose. We report on the quality of life following treatment for a malignant primary bone tumour around the knee in skeletally immature children. Patients. Patients (n = 41; mean age = 18 years; range 8–28) had all experienced chemotherapy in a neo-adjuvant setting, surgical excision of the tumour and endoprosthetic replacement. Methods. Interviews were conducted separately with the child and mother and focused on mobility, body image and the impact of treatment on schooling, employment and plans for the future. Results. Mobility in the group was variable. Only 12% reported that they could run with any confidence. The proportion who were able to swim (49%) or ride a bike (46%) was higher. All had experienced major disruption in schooling (mean absence following diagnosis = 12 months). Eight had repeated a school year and 41% patients reported that their schoolwork was affected. As a result of their experience, eight (six females and two males) chose health-related employment. Concerns for the future were highest among males and those with manual jobs. Three patients were receiving psychiatric support, in relation to extreme concern about the risk of recurrence. All expressed satisfaction with treatment, and older patients believed that the prosthesis gave a better quality of life than amputation. Discussion. Our data suggest that outcome following limb-salvage surgery is variable. Education is disrupted. Even so, only two left school with no qualifications. Employment is most restricted among males with few qualifications who may benefit from sensitive vocational counselling. PMID:18521199

    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. Survival of EHPM improve could be explained by early diagnosis and improve treatment of cancers. PMID:27444261

    This report describes a primary clitoral adenocarcinoma in a dog with secondary hypercalcemia of malignancy. A 10-year-old, spayed female basset hound was evaluated for a mass protruding from the vulva. The mass was excised, and a histological diagnosis of clitoral adenocarcinoma was made. No evidence of metastasis on thoracic radiographs or abdominal ultrasound was seen. Preoperative hypercalcemia resolved following excision of the mass. Cellular features were similar to an apocrine gland anal sac adenocarcinoma, and immunohistochemistry exhibited features noted with apocrine gland anal sac adenocarcinoma. No further treatment was elected by the owner. Internal iliac lymph-node metastasis was identified 4 weeks postoperatively, and hypercalcemia recurred 8 weeks postoperatively. The dog was euthanized 22 weeks postoperatively for signs related to hypercalcemia, including polyuria/polydipsia, lethargy, and weakness. A necropsy was performed and confirmed the presence of internal iliac lymph-node metastasis. The colon, rectum, and anal sacs were grossly and histologically normal. To our knowledge, this is the first reported case of clitoral neoplasia in the dog.

    This case report describes a 37-year-old female who was admitted to our Emergency Department because of shortness of breath. On physical examination, she had dyspnea and tachycardia and blood pressure was 80/50 mmHg with a pulsus paradoxus of 22 mmHg. Neck veins were distended, heart sounds were distant, and dullness was found on both lung bases. Her chest X-ray revealed bilateral pleural effusion and cardiomegaly. On both computed tomography and echocardiography the heart was of normal size and a large pericardial effusion was noted. The echocardiogram showed signs of impending tamponade, so the patient underwent an emergent pericardiocentesis. No infectious etiology was found and she was assumed to have viral pericarditis and was treated accordingly. However, when the pericardial effusion recurred and empirical therapy for tuberculosis failed, a pericardial window was performed. A typical staining pattern for mesothelioma was found on her pericardial biopsy specimen. Since no other mesodermal tissue was affected, a diagnosis of primary malignant pericardial mesothelioma was made. Chemotherapy was not effective and she passed away a year after the diagnosis was made. This case highlights the difficulties in diagnosing this uncommon disease in patients that present with the common finding of pericardial effusion. PMID:28003826

    Wide variation exists in ovarian cancer incidence rates suggesting the importance of environmental factors. Due to increasing environmental pollution, trace elements and heavy metals have drawn attention in studies defining the etiology of cancer, but scant data is available for ovarian cancer. Our aim was to compare the tissue concentrations of lead, selenium and nickel in epithelial ovarian cancer, borderline tumor and healthy ovarian tissues. The levels of lead, selenium and nickel were estimated using atomic absorption spectrophotometry in formalin-fixed paraffin-embedded tissue samples. Tests were carried out in 20 malignant epithelial ovarian cancer, 15 epithelial borderline tumor and 20 non-neoplastic healthy ovaries. Two samples were collected for borderline tumors, one from papillary projection and one from the smooth surface of cyst wall. Pb and Ni concentrations were found to be higher both in malignant and borderline tissues than those in healthy ovaries. Concentrations of Pb and Ni in malignant tissues, borderline papillary projections and capsular tissue samples were not different. Comparison of Se concentrations of malignant, borderline and healthy ovarian tissues did not reveal statistical difference. Studied metal levels were not found to be different in either papillary projection or in cyst wall of the borderline tumors. This study revealed the accumulation of lead and nickel in ovarian tissue is associated with borderline and malignant proliferation of the surface epithelium. Accumulation of these metals in epithelial ovarian cancer and borderline ovarian tumor has not been demonstrated before. Copyright © 2017 Elsevier GmbH. All rights reserved.

    In the diagnostic process of primary bone tumors, patient age, tumor localization and to a lesser extent sex affect the differential diagnosis. We therefore aim to develop a pretest probability calculator for primary malignant bone tumors based on population data taking these variables into account. We access the SEER (Surveillance, Epidemiology and End Results Program of the National Cancer Institute, 2015 release) database and analyze data of all primary malignant bone tumors diagnosed between 1973 and 2012. We record age at diagnosis, tumor localization according to the International Classification of Diseases (ICD-O-3) and sex. We take relative probability of the single tumor entity as a surrogate parameter for unadjusted pretest probability. We build a probabilistic (naïve Bayes) classifier to calculate pretest probabilities adjusted for age, tumor localization and sex. We analyze data from 12,931 patients (647 chondroblastic osteosarcomas, 3659 chondrosarcomas, 1080 chordomas, 185 dedifferentiated chondrosarcomas, 2006 Ewing's sarcomas, 281 fibroblastic osteosarcomas, 129 fibrosarcomas, 291 fibrous malignant histiocytomas, 289 malignant giant cell tumors, 238 myxoid chondrosarcomas, 3730 osteosarcomas, 252 parosteal osteosarcomas, 144 telangiectatic osteosarcomas). We make our probability calculator accessible at http://ebm-radiology.com/bayesbone/index.html . We provide exhaustive tables for age and localization data. Results from tenfold cross-validation show that in 79.8 % of cases the pretest probability is correctly raised. Our approach employs population data to calculate relative pretest probabilities for primary malignant bone tumors. The calculator is not diagnostic in nature. However, resulting probabilities might serve as an initial evaluation of probabilities of tumors on the differential diagnosis list.

    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.

    Steroidogenic factor 1 (SF-1) gene, identified by Keith Parker in 1992, encodes for an orphan nuclear receptor, NR5A1, whose expression is detected during fetal life in adrenal and gonadal steroidogenic tissues, but also in the developing hypothalamus and in pituitary gonadotropic cells. SF-1 knock-out mouse models exhibit complete adrenal and gonadal agenesis. Human mutations of this transcription factor, were initially associated with primary adrenal failure and male gonadal dysgenesis with various degrees of under androgenization. More recently, identification of novel SF-1 mutations responsible for isolated 46, XY gonadal dysgenesis or 46, XX primary ovarian insufficiency, underscores its central role in the control and maintenance of adrenal and reproductive functions. A better understanding in the regulatory mechanisms of SF-1 signaling pathway, will open new avenues for diagnostic and therapeutic managements of sex differentiation disorders and infertilities.

    The activated ras oncogene that is present in Harvey sarcoma virus is able to induce malignant transformation of pure cultures of mouse primary keratinocytes. Malignant transformation of these cells is demonstrated by their ability to form carcinomas when grafted back onto syngeneic animals. However, expression of the malignant phenotype by the ras-transformed keratinocytes is drastically inhibited by the presence of normal dermal fibroblasts. This inhibitory effect depends on the ratio of fibroblasts to keratinocytes. It can be observed with mitomycin C-treated growth-arrested dermal fibroblasts and not with other cells, such as normal keratinocytes or established fibroblasts. Thus, a cellular environment approximating normal tissue can suppress tumor formation triggered by a single oncogene.

    Objective BRCA-associated and sporadic ovarian cancers have different pathologic and clinical features. Our goal was to determine if BRCA mutation status is an independent predictor of residual tumor volume following primary surgical cytoreduction. Methods We conducted a retrospective analysis of patients with FIGO stage IIIC-IV high-grade serous ovarian cancer classified for the presence or absence of germline BRCA mutations. The primary outcome was tumor-debulking status categorized as complete gross resection (0mm), optimal but visible disease (1-10mm), or suboptimal debulking (>10mm) following primary surgical cytoreduction. Overall survival by residual tumor size and BRCA status was also assessed as a secondary endpoint. Results Data from 367 patients (69 BRCA mutated, 298 BRCA wild-type) were analyzed. Rate of optimal tumor debulking (0-10mm) in BRCA wild-type and BRCA-mutated patients were 70.1% and 84.1%, respectively (P=0.02). On univariate analysis, increasing age (10-year OR, 1.33; 95% CI, 1.07–1.65; P=0.01) and wild-type BRCA status (OR, 0.47; 95% CI, 0.23–0.94, P=0.03) were both significantly associated with suboptimal surgical outcome. On multivariate analysis, BRCA mutation status was no longer associated with residual tumor volume (OR, 0.63; 95% CI, 0.31–1.29; P=0.21) while age remained a borderline significant predictor (10-year OR, 1.25; 95% CI,1.01–1.56; P=0.05). Both smaller residual tumor volume and mutant BRCA status were significantly associated with improved overall survival. Conclusion BRCA mutation status is not associated with the rate of optimal tumor debulking at primary surgery after accounting for differences in patient age. Improved survival of BRCA carriers is not the result of better surgical outcomes but instead intrinsic tumor biology. PMID:22579790

    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 carcinomas without destructive stromal invasion indicate that these tumors have a very limited malignant potential. The literature has not documented recurrences in this setting when the staging has been complete, the sampling adequate, and the cytologic features no more than grade 2, and metastasis to the ovary has been excluded. In contrast, carcinomas harboring even limited foci of destructive stromal invasion, although frequently cured surgically, can pursue a malignant clinical course.

    AIM: To study computed tomography (CT) features of abdominal malignant fibrous histiocytoma (MFH) in various rare locations. METHODS: We retroprospectively identified cases of MFH involving the abdominal cavity. Particular attention was paid to details regarding imaging features and histological types. RESULTS: The study population consisted of seven men and one woman, with a mean age of 52.5 years. Seven patients had some physical symptoms, while one was incidentally detected. The sites of origin were liver (n = 3), greater omentum (n = 1), superior mesentery (n = 1), ileum (n = 1), right psoas muscle (n = 1) and right kidney (n = 1). With the exception of the ileum lesion, all were of huge size. The contour of the lesions was more or less clear. Foci of necrosis were present in six lesions (n = 6). On plain CT scan, all lesions were hypo to iso dense. The lesion in the greater omentum was cystic. One lesion (n = 1) showed significant enhancement and the cystic lesion showed mild peripheral enhancement. An abundance of blood vessels surrounding the mass was seen in two lesions (n = 2) and both were of the inflammatory variety. Pathological examination revealed storiform-pleomorphic variety (n = 4), inflammatory variety (n = 3) and myxoid variety (n = 1). Two of the patients with inflammatory MFH had a clinical presentation of fever and one was afebrile, however, blood investigations in all three showed leukocytosis. CONCLUSION: Primary MFHs of the abdominal viscera and gastrointestinal tract are generally huge soft tissue masses containing areas of low attenuation and mild to moderate contrast enhancement.

    Second primary malignancies (SPMs) are among the most serious late adverse effects after radiotherapy experienced over time by the increasing population of cancer survivors worldwide. The study aim was to determine the rate and distribution of SPMs for neutron- and photon-emitting brachytherapy (BT) sources for patients treated for cervical cancer. The cohort comprised 662 patients with invasive cervical cancer (Stages IIB and IIIB) and contributed 5,224 patient-years (PY) of observation. These patients were treated by radiotherapy during the 1989-1999 year period with cobalt-60 source ((60)Co) teletherapy. The first group of patients (N = 375; 3,154 PY) received high-dose-rate (HDR) californium-252 source ((252)Cf) BT, whereas the second group (N = 287; 2,070 PY) received HDR (60)Co BT. Over a 25-year period, 35 SPMs were observed, amounting to 5.3% of all observed patients: in 16 (2.4%) heavily, 2 (0.3%) moderately, 14 (2.1%) lightly irradiated body sites, and 3 (0.5%) other sites. Of these, 21 cases (5.6%) were observed in the HDR (252)Cf BT group, whereas 14 cases (4.9%) were observed in the HDR (60)Co BT group. Exposures received during (60)Co teletherapy and HDR BT with either (252)Cf or (60)Co had statistically equivalent (p = 0.68) effects on SPM development. Cure rates are improving, and therefore, there are more long-term survivors from cervical cancer. This study shows no significant difference in rates or distribution of SPMs in women treated with neutron BT compared with photon BT (p = 0.68). After reviewing related literature and our research results, it is evident that a detailed investigation of SPM frequency, localization, and dose to adjacent organs is a suitable topic for further research.

  10. Generation of MHC class I diversity in primary tumors and selection of the malignant phenotype.

    Intratumor heterogeneity among cancer cells is promoted by reversible or irreversible genetic alterations and by different microenvironmental factors. There is considerable experimental evidence of the presence of a variety of malignant cell clones with a wide diversity of major histocompatibility class I (MHC-I) expression during early stages of tumor development. This variety of MHC-I phenotypes may define the evolution of a particular tumor. Loss of MHC-I molecules frequently results in immune escape of MHC-negative or -deficient tumor cells from the host T cell-mediated immune response. We review here the results obtained by our group and other researchers in animal models and humans, showing how MHC-I intratumor heterogeneity may affect local oncogenicity and metastatic progression. In particular, we summarize the data obtained in an experimental mouse cancer model of a methylcholanthrene-induced fibrosarcoma (GR9), in which isolated clones with different MHC-I expression patterns demonstrated distinct local tumor growth rates and metastatic capacities. The observed "explosion of diversity" of MHC-I phenotypes in primary tumor clones and the molecular mechanism ("hard"/irreversible or "soft"/reversible) responsible for a given MHC-I alteration might determine not only the metastatic capacity of the cells but also their response to immunotherapy. We also illustrate the generation of further MHC heterogeneity during metastatic colonization and discuss different strategies to favor tumor rejection by counteracting MHC-I loss. Finally, we highlight the role of MHC-I genes in tumor dormancy and cell cycle control. © 2014 UICC.

    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.

    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.

    Collagen type XVIII (C18) is a nonfibrillar collagen of basement membranes. Its C-terminal fragment, endostatin, has been identified as an inhibitor of angiogenesis. C18 is predominantly expressed by hepatocytes of normal, cirrhotic and neoplastic liver. We compared the patterns of C18 RNA-expression in colonic adenocarcinoma metastases, which represent the most frequently occurring liver tumours, to normal colon mucosa, to primary colon cancers and to ovarian cancers which are often morphologically similar to colonic cancer or metastasis. Two C18-specific RNA-probes were generated to perform in situ hybridization combined with immunohistochemistry for cytokeratin, vimentin and the endothelial marker CD31, in order to characterize the C18-expressing cells. C18/endostatin protein was localized by immunohistology. In colorectal carcinomas and their liver metastases high levels of C18 transcripts were observed in endothelial cells and fibroblasts/myofibroblasts, whereas C18 RNA was virtually absent from carcinoma cells. Ovarian carcinomas displayed high C18 RNA expression both in carcinoma and stromal cells, indicating that induction of C18 transcription in tumour stromal cells is independent of the ability of carcinoma cells to express C18. While the role of tumour cell derived C18 in cancer growth regulation remains unknown, stimulation of proteolysis of the locally strongly expressed C18 to endostatin could offer an attractive approach for a targeted antineoplastic therapy. © 2001 Cancer Research Campaign   http://www.bjcancer.com PMID:11720442

    Single original gemcitabine is commonly used as salvage treatment in platinum-resistant ovarian cancer, fallopian tube cancer and primary peritoneal adenocarcinoma (PPA) with a satisfactory outcome. However, efficacy data fro this regimen are limited. We therefore conducted a retrospective study to evaluate the outcome of patients who received single-agent generic gemcitabine (GEMITA) after development of clinical platinum resistance. The study period was between May 2008 and December 2010. Gemcitabine was administered intravenously in two different schedules: 1,000 mg/m2 on day 1,8, and 15 every 28 days; and on days 1 and 8 every 21 days with the same dosage. Administration was until disease progression was noted. The response rate was evaluated using the Gynecologic Cancer Intergroup (GCIG ) criteria while toxicity was evaluated according to WHO criteria. Sixty-six patients met the inclusion criteria in the study period. Two-thirds of them received gemcitabine as the second and third line regimen. The overall response rate was 12.1%. The median progression free survival and overall survival was 2 and 10 months, respectively. With the total 550 courses of chemotherapy, the patients developed grades 3 and 4 hematologic toxicity as follows: anemia, 1.5%; leukopenia, 13.7%; neutropenia, 27.3%; and thrombocytopenia, 3.0%. In conclusion, single agent generic gemcitabine revealed a modest efficacy in patients with platinum-resistant ovarian cancer, fallopian tube cancer and PPA without serious toxicity.

    We report the case of a 76-year-old man with a malignant fibrous histiocytoma of the right ventricle and main pulmonary trunk, diagnosed through echocardiography and catheterization. Extensive resection of the right ventricular outflow tract, pulmonary valve apparatus, and main pulmonary trunk was performed, and the defect was repaired with a valveless ventriculo-pulmonary Dacron graft. The patient recovered uneventfully, and was doing well 18 months after surgery. To our knowledge, this is only the 15th case of primary malignant fibrous histiocytoma of the heart that has been documented in the literature since histologic criteria and cases were published in 1977-78, and the 2nd such case of a primary tumor that has arisen in a right cardiac chamber. The case is presented in detail, along with a review of the literature since 1978. (Texas Heart Institute Journal 1989;16:296-304) Images PMID:15227385

    Increased incidence of a second primary aero-digestive malignancy after an index head and neck cancer (HNC) is well-documented. Furthermore, a clear set of surveillance strategies for second primary aero-digestive cancers in these patients exists. The goal of this article is to review the published literature on risk of second primary malignancies (SPMs) (including aero-digestive malignancies) after a treated index HNC as well as its associated predictors, prognosis and surveillance. Most relevant publications were identified through searching the PubMed database for articles published up to July 2012; epidemiologic evidence was synthesized and thoroughly analyzed. Data from randomized controlled trials, meta-analyses, population-based and cohort group studies, prior reviews, and case reports indicate an increased incidence of various SPMs after occurrence of a HNC. These cancers are not limited to upper aero-digestive sites. Common risk factors including environmental, genetic and immune factors may explain the increased incidence of second cancers in this patient population. In addition, site of the index HNC may predict the site of a future SPM. As a general rule, oral cavity and oropharyngeal squamous cell cancers are associated more with head and neck region SPM, while laryngeal and hypopharyngeal cancers - with that of the lung. As these cancers confer dismal prognosis and shorter survival in patients with HNCs, several literature sources recommend close surveillance for and an aggressive therapy of SPM. Notwithstanding, their optimal management and follow-up schedule remains to be established.

    A retrospective study on the Primary Cutaneous Malignant Melanoma in the Hospital do Servidor Público Estadual de São Paulo (HSPE-SP) analyzing its distribution according to age, sex, race and cutaneous site. We studied 222 patients with Primary Cutaneous Malignant Melanoma as diagnosed at Hospital do Servidor Público Estadual de São Paulo, Brazil between the period from 1963 to 1997. A retrospective study was performed. Data were expressed as inance of caucasians (98.19%) over afro-americans (1.81) and of the female sex (69.36%) over the male sex (30.63%) was found. The predominant age on the occasion of the diagnosis was between 50 and 60 years for the women (25.32%) and between 60 and 69 years for the men (22.52%). The most frequent site of the cancer in men was the back region (29.41%) and in the lower members in the women (38.31%). The most frequent level of the tumor invasion (Clark) was IV (39.77%), and the average of tumor thickeness (Breslow) was < 0.75 mm (28.4%). A 5 years survival was observed in 73.3% of the patients. At our Hospital the incidence of Primary Cutaneous Malignant Melanoma has shown an increase in recent years; these results are compatible with the most recent international surveys.

    The in vitro growth of ovarian follicles is an emerging technology for fertility preservation. Various strategies support the culture of secondary and multilayer follicles from various species including mice, non-human primate, and human; however, the culture of early stage (primary and primordial) follicles, which are more abundant in the ovary and survive cryopreservation, has been limited. Hydrogel-encapsulating follicle culture systems that employed feeder cells, such as mouse embryonic fibroblasts (MEFs), stimulated the growth of primary follicles (70-80 µm); yet, survival was low and smaller follicles (<70 µm) rapidly lost structure and degenerated. These morphologic changes were associated with a breakdown of the follicular basement membrane; hence, this study investigated ascorbic acid based on its role in extracellular matrix (ECM) deposition/remodeling for other applications. The selection of ascorbic acid was further supported by a microarray analysis that suggested a decrease in mRNA levels of enzymes within the ascorbate pathway between primordial, primary, and secondary follicles. The supplementation of ascorbic acid (50 µg/mL) significantly enhanced the survival of primary follicles (<80 µm) cultured in alginate hydrogels, which coincided with improved structural integrity. Follicles developed antral cavities and increased to diameters exceeding 250 µm. Consistent with improved structural integrity, the gene/protein expression of ECM and cell adhesion molecules was significantly changed. This research supports the notion that modifying the culture environment (medium components) can substantially enhance the survival and growth of early stage follicles. © 2013 Wiley Periodicals, Inc.

    Ovarian cancer is the commonest cause of gynaecological cancer death in the UK, and guidelines for initial surgery and staging of this disease are widely available. We report a retrospective audit of the surgical management of patients with newly diagnosed ovarian cancer referred to the Christie Cancer Centre in Manchester in 1996. The aim was to assess compliance with surgical guidelines. The authors found that the majority of patients (92%) presented via an outpatient clinic and for these individuals surgery was therefore elective. This mode of presentation should allow management by a small number of dedicated gynaecologists at each hospital, but up to seven consultants in each hospital performed surgery on a relatively small number of patients. Furthermore, less than half the patients underwent the recommended surgical procedure. Although some patients may have ‘inoperable’ disease, these data suggest that a greater compliance with national and international guidelines are required to provide an optimal level of care. © 1999 Cancer Research Campaign PMID:10408851
