    Recurrence is a common event in endothelial ovarian cancer (EOC) patients, and the choice of the most appropriate treatment is driven by the platinum-free interval, molecular characteristics of the disease such as BRCA mutational status, previous treatments and toxicity. Areas covered: This review focuses on the main hematologic and non-hematologic toxicities correlated with the use of licensed antiangiogenic agents and PARP inhibitors in recurrent platinum-sensitive EOC, providing recommendations for their management. Expert opinion: The clinical research over the next years will be focused on a more precise characterization of molecular pathways underlying tumorigenesis of the five ovarian tumors, to improve the decision-making process in these rare diseases. For this purpose, new study designs and international collaborations will become mandatory. Immunotherapy, antiangiogenic agents and PARP inhibitors will be combined to build a treatment strategy algorithm which will allow patients to receive all the available treatment option, in the more appropriate sequence.

    Olaparib (O), a polyADPribose polymerase (PARP) inhibitor, and cediranib (C), a VEGF receptor (VEGFR)1-3 inhibitor together had greater activity than O alone in women with recurrent platinum-sensitive ovarian cancer (OvCa). The objective of this study is to identify potential lead biomarker candidates for response to O + C in the setting of a multi-institutional phase II study of O with and without C in recurrent platinum-sensitive OvCa. A self-selected group of patients participated in a prospectively planned exploratory biomarker substudy of the randomized phase II study of O versus O + C. Whole blood for peripheral blood mononuclear cell (PBMC) and plasma isolation was collected prior to and on day 3 of treatment. Quantitation of circulating endothelial cells (CEC), IL-6, IL-8, VEGF, and soluble VEGFR-2 plasma concentrations, and polyADPribose (PAR) incorporation were performed. Single nucleotide polymorphism analysis of XRCC1 280H, R194W, and Q399R was done. Dynamic contrast-enhanced-magnetic resonance imaging (DCE-MRI) was performed at baseline and day 3 of treatment. Parameter changes were compared between the two arms using an exact Wilcoxon rank sum test. Kaplan-Meier and log-rank tests were used to examine survival outcome. Thirteen patients elected to participate in the translational substudy, seven patients on O and six patients on O + C. Patients on O + C had a greater decrease in IL-8 concentration and larger CEC fold increase compared with those on O alone (p = 0.026, p = 0.032). The fold increase in CEC on day 3 was associated with duration of progression-free survival (PFS) (R (2) = 0.77, 95% CI 0.55-0.97, p < 0.001). IL-8 post-pretreatment changes correlate with PFS (p = 0.028). XRCC1 DNA polymorphisms were not related to PFS. All patients had reduction in PAR incorporation, and all except one had reduction in vascular flow on DCE-MRI. Our exploratory correlative studies indicate that CEC and IL-8 changes may be

    Combining histone deacetylase inhibitors and chemotherapy is synergistic. This phase I study combined escalating vorinostat doses with constant doses of carboplatin and gemcitabine for the treatment of recurrent platinum-sensitive ovarian cancer. The objectives of this study were to determine the maximally tolerated dose of this combination; secondary objectives included preliminary response rate of this regimen and toxicity profile. Fifteen patients with relapsed ovarian cancer were enrolled into this phase I study. Doses of carboplatin and gemcitabine were AUC 4 on day 1 and 1000 mg/m(2) on days 1 and 8, respectively; cycles were administered every 21 days. Vorinostat was tested using four different schedules. The first dose level (DL A) tested vorinostat as daily oral dosing from days 1 to 14. DL B tested twice daily (BID) vorinostat dosing on days 1-3 and 8-10. DL C tested BID vorinostat dosing on days 1, 2, 8, and 9, starting vorinostat 1 day prior to initiation of carboplatin and gemcitabine, and DL D tested vorinostat on days 1 and 2 with chemotherapy starting on day 2. All four DLs tested resulted in dose-limiting toxicities, and no MTD was determined. Toxicities were mostly hematologic. Seven patients were evaluable for RECIST assessment, and six of them had partial responses (PR) via RECIST. Combination of carboplatin, gemcitabine, and vorinostat has activity in relapsed platinum-sensitive ovarian cancer, but was difficult to combine because of hematologic toxicities in this phase I study. No maximally tolerated dose was found, and the study was terminated early.

    Olaparib is a poly(ADP-ribose) polymerase inhibitor and cediranib is an anti-angiogenic agent with activity against VEGF receptor (VEGFR) 1, VEGFR2, and VEGFR3. Both oral agents have antitumour activity in women with recurrent ovarian cancer, and their combination was active and had manageable toxicities in a phase 1 trial. We investigated whether this combination could improve progression-free survival (PFS) compared with olaparib monotherapy in women with recurrent platinum-sensitive ovarian cancer. In our randomised, open-label, phase 2 study, we recruited women (aged ≥18 years) who had measurable platinum-sensitive, relapsed, high-grade serous or endometrioid ovarian, fallopian tube, or primary peritoneal cancer, or those with deleterious germline BRCA1/2 mutations from nine participating US academic medical centres. We randomly allocated participants (1:1) according to permuted blocks, stratified by germline BRCA status and previous anti-angiogenic therapy, to receive olaparib capsules 400 mg twice daily or the combination at the recommended phase 2 dose of cediranib 30 mg daily and olaparib capsules 200 mg twice daily. The primary endpoint was progression-free survival analysed in the intention-to-treat population. The phase 2 trial is no longer accruing patients. An interim analysis was conducted in November, 2013, after 50% of expected events had occurred and efficacy results were unmasked. The primary analysis was performed on March 31, 2014, after 47 events (66% of those expected). The trial is registered with ClinicalTrials.gov, number NCT01116648. Between Oct 26, 2011, and June 3, 2013, we randomly allocated 46 women to receive olaparib alone and 44 to receive the combination of olaparib and cediranib. Median PFS was 17·7 months (95% CI 14·7-not reached) for the women treated with cediranib plus olaparib compared with 9·0 months (95% CI 5·7-16·5) for those treated with olaparib monotherapy (hazard ratio 0·42, 95% CI 0·23-0·76; p=0·005).

    Background Olaparib is an oral poly(ADP-ribose) polymerase inhibitor and cediranib is an oral anti-angiogenic with activity against VEGFR-1, 2, and 3. Both agents have antitumor activity in women with recurrent ovarian cancer, and the combination of these agents was active and had manageable toxicities in a Phase 1 trial. We asked whether the combination of cediranib and olaparib could improve progression-free survival compared to olaparib monotherapy in women with recurrent platinum-sensitive ovarian cancer. Methods We conducted a randomized, open-label, phase 2 study to evaluate the activity of olaparib monotherapy compared with combination cediranib and olaparib in women with ovarian cancer with measurable platinum-sensitive, relapsed, high-grade serous or endometrioid disease or those with deleterious germline BRCA1/2 mutations (gBRCAm). Patients were randomized using permuted blocks within stratum defined by gBRCA status and prior anti-angiogenic therapy to receive olaparib capsules 400mg twice daily or the combination at the recommended phase 2 dose of cediranib 30mg daily and olaparib capsules 200mg twice daily. The primary endpoint was progression-free survival (PFS) analyzed under intention to treat. The trial is registered with ClinicalTrials.gov, NCT01116648. The Phase 2 portion of the trial reported here is no longer accruing patients. Findings Forty-six of 90 randomized patients received olaparib alone, and 44 received cediranib/olaparib. Median PFS was significantly longer with cediranib/olaparib (17.7 vs. 9.0 mos, HR 0.42; p = 0.005). Grade 3 and 4 adverse events were more common with cediranib/olaparib, including fatigue (12 vs. 5), diarrhea (10 vs. 0), and hypertension (18 vs. 0). Subset analysis within stratum defined by BRCA1/2 status demonstrated activity of cediranib/olaparib in both gBRCAm and gBRCAwt/u (wild-type/unknown) patients. Significant improvement in PFS occurred in gBRCAwt/u women receiving cediranib/olaparib (16.5 vs. 5.7 mos, p = 0

    The aim of this study was to determine whether the response rate for the paclitaxel-carboplatin combination is superior to carboplatin alone in the treatment of patients with platinum-sensitive recurrent ovarian carcinoma. Patients with recurrent ovarian carcinoma, 6 months after treatment with a platinum-based regimen and with no more than two previous chemotherapy lines, were randomized to receive carboplatin area under the curve (AUC) 5 (arm A) or paclitaxel 175 mg/m(2) + carboplatin AUC 5 (arm B). The primary end point was objective response, following a 'pick up the winner' design. Secondary end points included time to progression (TTP), overall survival, tolerability and quality of life (QoL). Eighty-one patients were randomized and included in the intention-to-treat analysis. The response rate in arm B was 75.6% [26.8% complete response (CR) + 48.8% partial response (PR)] [95% confidence interval (CI) 59.7% to 87.6%] and 50% in arm A (20% CR + 30% PR) (95% CI 33.8% to 66.2%). No significant differences were observed in grade 3-4 hematological toxicity. Conversely, mucositis, myalgia/arthralgia and peripheral neurophaty were more frequent in arm B. Median TTP was 49.1 weeks in arm B (95% CI 36.9-61.3) and 33.7 weeks in arm A (95% CI 25.8-41.5). No significant differences were found in the QoL analysis. Paclitaxel-carboplatin combination is a tolerable regimen with a higher response rate than carboplatin monotherapy in platinum-sensitive recurrent ovarian carcinoma.

    Full Text Available The choice of second-line chemotherapy in patients with recurrent ovarian cancer (ROC is complex, with several factors to be considered, the most important of which is the length of the platinum-free treatment interval (PFI. Recently ROC patients have been further stratified into platinum sensitive (PS, partially platinum sensitive (PPS and platinum resistant (PR subgroups depending on the length of the PFI. Response to second-line therapy, progression-free survival (PFS and overall survival (OS are linked to the PFI, all of them improving as the PFI increases. Consequently, there is increasing interest in PFI extension strategies with platinum-free therapeutic options. Such strategies are currently being studied in patients with partially platinum-sensitive disease (PFI 6-12 months, as the treatment of these patients remains clinically challenging. A non-platinum option, trabectedin + pegylated liposomal doxorubicin (PLD combination, has been evaluated in ROC patients in the pivotal phase III OVA-301 study. The OVA-301 study differed from previous trials in the same setting as it included only patients who were not expected to benefit from or who were ineligible for or who were unwilling to receive re-treatment with platinum-based chemotherapy, including those with PPS and PR disease. Subset analysis of patients with PPS disease in OVA-301 showed that the trabectedin + PLD combination significantly improved PFS compared with PLD alone; median PFS 7.4 versus 5.5 months, p=0.0152. Final survival data from the same subset of patients, showed that trabectedin + PLD also achieved a significant 36% decrease in the risk of death compared with PLD alone (HR=0.64; 95% CI, 0.47–0.88; p=0.0027. Median overall survival (OS was 22.4 months in the trabectedin + PLD arm versus 16.4 months in the PLD arm. This represents a statistically significant 6-month improvement in median OS in patients treated with trabectedin + PLD compared to those treated with PLD

    Full Text Available Abstract Background Platinum-based combinations are the standard second-line treatment for platinum-sensitive ovarian cancer (OC. This randomized phase II study was undertaken in order to compare the combination of carboplatin and pegylated liposomal doxorubicin (LD with carboplatin and paclitaxel (CP in this setting. Methods Patients with histologically confirmed recurrent OC, at the time of or more than 6 months after platinum-based chemotherapy, were randomized to six cycles of CP (carboplatin AUC5 + paclitaxel 175 mg/m2, d1q21 or CLD (carboplatin AUC5 + pegylated LD 45 mg/m2, d1q28. Results A total of 189 eligible patients (CP 96, CLD 93, with a median age of 63 years, median Performance Status (PS 0 and a median platinum free interval (PFI of 16.5 months, entered the study. Discontinuation due to toxicity was higher in the CP patients (13.5% versus 3%, P = 0.016. The overall response rate was similar: CP 58% versus CLD 51%, P = 0.309 (Complete Response; CR 34% versus 23% and there was no statistical difference in time-to-progression (TTP or overall survival (OS; TTP 10.8 months CP versus 11.8 CLD, P = 0.904; OS 29.4 months CP versus 24.7 CLD, P = 0.454. No toxic deaths were recorded. Neutropenia was the most commonly seen severe toxicity (CP 30% versus CLD 35%. More frequent in CLD were severe thrombocytopenia (11% versus 2%, P = 0.016, skin toxicity and Palmar-plantar erythrodysesthesia (PPE grade 1-2 (38% versus 9%, PP = 0.029, 20% versus 5%, P = 0.003. PS and PFI were independent prognostic factors for TTP and OS. Conclusions The combination of pegylated LD with carboplatin is effective, showing less neurotoxicity and alopecia than paclitaxel-carboplatin. It thus warrants a further phase III evaluation as an alternative treatment option for platinum-sensitive OC patients.

    A xenobank of patient-derived (PDX) ovarian tumor samples has been established consisting of tumors with different sensitivity to cisplatin (DDP), from very responsive to resistant. As the DNA repair pathway is an important driver in tumor response to DDP, we analyzed the mRNA expression of 20 genes involved in the nucleotide excision repair, fanconi anemia, homologous recombination, base excision repair, mismatch repair and translesion repair pathways and the methylation patterns of some of these genes. We also investigated the correlation with the response to platinum-based therapy. The mRNA levels of the selected genes were evaluated by Real Time-PCR (RT-PCR) with ad hoc validated primers and gene promoter methylation by pyrosequencing. All the DNA repair genes were variably expressed in all 42 PDX samples analyzed, with no particular histotype-specific pattern of expression. In high-grade serous/endometrioid PDXs, the CDK12 mRNA expression levels positively correlated with the expression of TP53BP1, PALB2, XPF and POLB. High-grade serous/endometrioid PDXs with TP53 mutations had significantly higher levels of POLQ, FANCD2, RAD51 and POLB than high-grade TP53 wild type PDXs. The mRNA levels of CDK12, PALB2 and XPF inversely associated with the in vivo DDP antitumor activity; higher CDK12 mRNA levels were associated with a higher recurrence rate in ovarian patients with low residual tumor. These data support the important role of CDK12 in the response to a platinum based therapy in ovarian patients. PMID:29872499

    Purpose: The aim of this study was to investigate efficacy and toxicity of the dose-dense weekly paclitaxel (T) and carboplatin (C) in the management of platinum-resistant/sensitive recurrent epithelial ovarian cancer (EOC) previously treated with 3 weekly paclitaxel/carboplatin. Methods: Thirty two patients with recurrent EOC who had received 3 weekly TC before were enrolled. Nine patients relapsed within 6 months (platinum-resistant), 13 patients relapsed after 12 months (platinum-sensitive) and in 10 patients recurrence occurred between 6 and 12 months (intermediate platinum-sensitive). Weekly (T) at a dose of 80 mg/m2, followed by weekly (C) AUC 2 on day 1, 8, and 15 of a 28-day cycle for 6 planned cycles were administrated. End-points were overall response rate (ORR), progression free survival (PFS), overall survival (OS) and toxicity. Results: The ORR was 62.5%. For the platinum-resistant, intermediate platinum-sensitive and platinum-sensitive patients the ORR was 44.4% (4/9), 60% (6/10) and 76.9% (10/13), respectively, and 1 (11.1%), 2 (20%) and 5 (38.46%) patients, respectively had CR. PFS was 9.1 months (6.13, 9.1 and 12.17 months, for the 3 groups, respectively) (P < 0.001). OS was 14 months (9.17, 15.2, and 19.23 months, for the 3 groups, respectively) (P < 0.001). Treatment-related adverse events were manageable with only 1 patient (3.1%) suffering from grade 4 neutropenia. Grade 3 hematological and non-hematological toxicities were neutropenia in 8 (25%), and peripheral neuropathy in 4 (12.5%) patients, respectively. Conclusion: Weekly TC is active and well-tolerated in platinum-resistant and platinum-sensitive patients with recurrent EOC previously treated with TC given every 3 weeks

    To investigate the efficacy and toxicity of immunomodulatory therapy (IMT) alone or as an add-on to palliative/salvage chemotherapy in patients with refractory/recurrent epithelial ovarian cancer (EOC). We retrospectively analyzed the efficacy and toxicity of IMT in 15 patients with refractory/recurrent EOC who had previously received multiple chemotherapy regimens. The median age of the patients was 56 years (range, 41-75 years). Three patients were platinum-sensitive, two were platinum-resistant, and the remaining 10 patients were refractory to platinum-based front-line chemotherapy. IMT consisted of picibanil (OK-432) on Day 1, interleukin-2 and/or interferon-α on Day 2 administered by subcutaneous injection (every week or 2-weekly). Five patients never received metronomic oral cyclophosphamide. After IMT, three patients achieved partial remission (PR, lasting for 11 months, ≥ 12 months, and 16 months), and six patients had stable disease (SD). The disease stabilizing rate (PR+SD) was 60% (3/3 in platinum-sensitive and 6/12 in platinum-resistant/refractory patients). The absolute lymphocyte count (ALC) at 1 month after IMT was significantly higher in the PR+SD group (median 1242.0/μL) than in the progression group (median 325.0/μL) (p = 0.012). No ≥ Grade 3 toxicities were observed. The median post-IMT survival time was 12 months (range, 2-39 months). IMT alone or add-on to palliative/salvage chemotherapy for refractory/recurrent EOC achieves a substantial disease stabilizing rate without severe toxicity, which might be a potential option in selected patients. The ALC 1 month after IMT could be an early indicator to disease stabilization. Copyright © 2015. Published by Elsevier B.V.

    Sunitinib is a multitargeted receptor tyrosine kinase inhibitor. We conducted a two-stage phase II study to evaluate the objective response rate of oral sunitinib in recurrent epithelial ovarian cancer. Eligibility required measurable disease and one or two prior chemotherapies, at least one platinum based. Platinum-sensitive or -resistant disease was allowed. Initial dose schedule was sunitinib 50 mg daily, 4 of 6 weeks. Observation of fluid accumulations during off-treatment periods resulted in adoption of continuous 37.5 mg daily dosing in the second stage of accrual. Of 30 eligible patients, most had serous histology (67%), were platinum sensitive (73%) and had two prior chemotherapies (60%). One partial response (3.3%) and three CA125 responses (10%) were observed, all in platinum-sensitive patients using intermittent dosing. Sixteen (53%) had stable disease. Five had >30% decrease in measurable disease. Overall median progression-free survival was 4.1 months. Common adverse events included fatigue, gastrointestinal symptoms, hand-foot syndrome and hypertension. No gastrointestinal perforation occurred. Single-agent sunitinib has modest activity in recurrent platinum-sensitive ovarian cancer, but only at the 50 mg intermittent dose schedule, suggesting that dose and schedule may be vital considerations in further evaluation of sunitinib in this cancer setting.

    Mucinous ovarian carcinoma have a poorer prognosis compared with other histological subtypes. The aim of this study was to evaluate, retrospectively, the activity of chemotherapy in patients with platinum sensitive recurrent mucinous ovarian cancer. The SOCRATES study retrospectively assessed the pattern of care of a cohort of patients with recurrent platinum-sensitive ovarian cancer observed in the years 2000–2002 in 37 Italian centres. Data were collected between April and September 2005. Patients with recurrent ovarian cancer with > 6 months of platinum free interval were considered eligible. Twenty patients with mucinous histotype and 388 patients with other histotypes were analyzed. At baseline, mucinous tumours differed from the others for an higher number of patients with lower tumor grading (p = 0.0056) and less advanced FIGO stage (p = 0.025). At time of recurrence, a statistically significant difference was found in performance status (worse in mucinous, p = 0.024). About 20% of patients underwent secondary cytoreduction in both groups, but a lower number of patients were optimally debulked in the mucinous group (p = 0.03). Patients with mucinous cancer received more frequently single agent platinum than platinum based-combination therapy or other non-platinum schedules as second line therapy (p = 0.026), with a response rate lower than in non-mucinous group (36.4% vs 62.6%, respectively, p = 0.04). Median time to progression and overall survival were worse for mucinous ovarian cancer. Finally, mucinous cancer received a lower number of chemotherapy lines (p = 0.0023). This analysis shows that platinum sensitive mucinous ovarian cancer has a poor response to chemotherapy. Studies dedicated to this histological subgroup are needed

    The aim of this paper is to describe a four health-state, semi-Markov model structure with health states defined by initiation of subsequent treatment, designed to make best possible use of the data available from a phase 2 clinical trial. The approach is illustrated using data from a sub-group of patients enrolled in a phase 2 clinical trial of olaparib maintenance therapy in patients with platinum-sensitive relapsed ovarian cancer and a BRCA mutation (NCT00753545). A semi-Markov model was developed with four health states: progression-free survival (PFS), first subsequent treatment (FST), second subsequent treatment (SST), and death. Transition probabilities were estimated by fitting survival curves to trial data for time from randomization to FST, time from FST to SST, and time from SST to death. Survival projections generated by the model are broadly consistent with the outcomes observed in the clinical trial. However, limitations of the trial data (small sample size, immaturity of the PFS and overall survival [OS] end-points, and treatment switching) create uncertainty in estimates of survival. The model framework offers a promising approach to evaluating cost-effectiveness of a maintenance therapy for patients with cancer, which may be generalizable to other chronic diseases.

    Metronomic oral cyclophosphamide has gained increasing interest in recent years as a promising maintenance therapy in advanced, platinum-sensitive, high-grade serous ovarian cancer (HGSOC). Metronomic treatment with cyclophosphamide refers to the frequent, usually daily, administration of a low (oral) dose of cyclophosphamide with no prolonged drug-free breaks. Main advantages of this treatment are the effective reduction of tumour activity, oral administration in an outpatient setting, low cost and the low toxicity profile. Metronomic oral cyclophosphamide can benefit patients suffering from types of cancer known to be sensitive to alkylating agents, such as platinum-sensitive HGSOC. In recent years, several publications have underlined the advantage of this regimen and possible explanations were explored. We here present a patient with multiple recurrences of metastasized HGSOC, platinum-sensitive, with an on-going complete response to monotherapy with oral cyclophosphamide. This observation supports that patients with relapsing HGSOC who responded to platinum-based chemotherapy and cannot continue platinum-based chemotherapy because of toxicity, can be offered a course of metronomic cyclophosphamide. This case may serve as a reminder that old drugs can be used successfully even in the age of new upcoming therapy such as anti-angiogenic agents (VEGF inhibitors) and poly-ADP-ribose polymerase (PARP) inhibitors.

    Full Text Available A 31-year-old nulliparous patient presents with a three-day history of right sided colicky abdominal pain and associated nausea. This patient has previously presented twice with right sided ovarian torsion with the background of polycystic ovaries in the last two consecutive years. Blood tests were normal. Due to previous history, there was a high index of clinical suspicion that this may be a further torsion. Therefore, the patient was taken to theatre for a diagnostic laparoscopy and a further right sided ovarian torsion was noted. At this time, oophoropexy was performed to the uterosacral ligament to prevent further torsion in order to preserve the patients’ fertility. In this article, we detail this case and also provide a discussion of ovarian torsion including risk factors, presentation, and current thoughts on management.

    Full Text Available Abstract Background While many of these agents have been compared in prospective clinical trials, the gemcitabine/platinumbased regimens have not been compared in a prospective, randomized clinical trial. While bothgemcitabine/carboplatin and gemcitabine/cisplatin have a similar ORR in separate clinical trials, the tworegimens have never been directly been compared. With overlapping dose-limiting toxicity of thrombocytopenia, the gemcitabine/carboplatin regimen has been challenging to employ in the clinical setting in previously treated ovarian cancer patients and is often associated with treatment delays and/or dose reductions. Gemcitabine/cisplatin can also be a challenge due to its dose limiting neuropathy and renal toxicity, especially in previously treated patients. In the absence of any prospective, head to head comparison this retrospective study was embarked upon to compare the response rate and toxicity profiles of gemcitabine/cisplatin verses gemcitabine/carboplatin for the treatment of platinum-sensitive verses platinum-resistant recurrent ovarian cancer. Methods This was a retrospective chart review study that identified patients that had received either gemcitabine/cisplatin or gemcitabine/carboplatin for treatment of recurrent ovarian cancer and compared documented hematological and non-hematological toxicity and response based on RECIST (v1.1. Data was evaluated based upon platinum sensitivity/resistance as well. Results A total of 93 patients were identified that had received a gemcitabine/platinum regimen with 48 with recurrent ovarian cancer that were included in the study. There were 21 patients in the gemcitabine/cisplatin arm and 27 patients identified in the gemcitabine/carboplatin arm. Objective response rate (ORR was greater in platinum-sensitive patients that received gemcitabine/carboplatin compared to gemcitabine/cisplatin (8 (67% vs 2 (25%, p < 0.05. Conversely, ORR was greater in platinum-resistant patients treated

    The superiority of frontline intraperitoneal (IP) over intravenous (IV) chemotherapy is well established in the treatment of epithelial ovarian cancer. However, the role of IP chemotherapy in the second-line setting has rarely been investigated. Consecutive patients diagnosed with recurrent epithelial, tubal and peritoneal cancers between January 2000 and December 2012 were recruited using a propensity score-matching technique to adjust relevant risk factors. In total, 310 patients were included in the final analysis (94 for platinum-refractory/resistant disease and 216 for platinum-sensitive disease). IP chemotherapy demonstrated significantly longer median progression-free survival than IV chemotherapy (4.9 vs. 2.4 months, p chemotherapy confers longer progression-free survival than IV chemotherapy. Large-scale clinical trials should be conducted to validate the true efficacy. © 2016 S. Karger AG, Basel.

    Features of ultrasound picture of morphologically verified recurrence of ovarian cancer in 21 patients are presented, who received combined treatment including cytoreductive surgery in the form of hysterectomy with oophorectomy, resection of the greater omentum and 6 courses of chemotherapy CAP for ovarian cancer stage III (FIGO). In all patients cytoreductive surgery was optimal--without residual tumor. Recurrence of the disease was detected in 12-48 months in 80.9% of the cases. Three variants of recurrence was revealed by ultrasonography: isolated peritoneal dissemination, in 14.2% of the cases, which was mainly detected during the first 12 months; single entities in the projection of the small pelvis (61.9%) and mixed form (local lesions of small pelvis and peritoneal dissemination) in 23.8% of the cases.

    The objective of this study was to evaluate the correlation between 25-OH vitamin D and ovarian cancer as a diagnostic marker or recurrence disease marker. We studied the following: (1) 61 women without gynecologic diseases, (2) 45 women affected by benign ovarian disease, (3) 46 women with recent diagnosis of ovarian cancer, (4) 26 follow-up women with recurrent ovarian cancer, and (5) 32 follow-up women with stable ovarian cancer. The 25-OH vitamin D was quantified with LUMIPULSE® G 25-OH vitamin D on LUMIPULSE® G 1200 (Fujirebio, Japan). As a threshold value, identified by ROC curve analysis, 20.2 ng/mL (sensitivity 73.3 %, specificity 84 %) was chosen corresponding to the limit between sufficient and insufficient 25-OH vitamin D according to the WHO. Low 25-OH vitamin D levels were observed in 26 % of women without gynecologic diseases, in 80 % of women with recent diagnosis of ovarian cancer and in 24 % women affected by benign ovarian diseases (p < 0.001). The follow-up study showed an insufficient level of 25-OH vitamin D in 73 % women with recurrent ovarian cancer and in 47 % women with stable ovarian cancer (p < 0.0003). This study showed that patients with ovarian cancer are often insufficient in 25-OH vitamin D compared to women with benign ovarian diseases. The women with recurrent ovarian cancer presented more often low levels compared to women with stable ovarian cancer. This study suggests that 25-OH vitamin D, due to its antiproliferative properties, can be a good marker for ovarian cancer also.

    Full Text Available Among the pharmaceutical options available for treatment of ovarian cancer, increasing attention has been progressively focused on pegylated liposomal doxorubicin (PLD, whose unique formulation prolongs the persistence of the drug in the circulation and potentiates intratumor accumulation. Pegylated liposomal doxorubicin (PLD has become a major component in the routine management of epithelial ovarian cancer. In 1999 it was first approved for platinum-refractory ovarian cancer and then received full approval for platinum-sensitive recurrent disease in 2005. PLD remains an important therapeutic tool in the management of recurrent ovarian cancer in 2012. Recent interest in PLD/carboplatin combination therapy has been the object of phase III trials in platinum-sensitive and chemonaïve ovarian cancer patients reporting response rates, progressive-free survival, and overall survival similar to other platinum-based combinations, but with a more favorable toxicity profile and convenient dosing schedule. This paper summarizes data clarifying the role of pegylated liposomal doxorubicin (PLD in ovarian cancer, as well as researches focusing on adding novel targeted drugs to this cytotoxic agent.

    Full Text Available Abstract Background MicroRNAs (miRNAs are small, noncoding RNAs that negatively regulate gene expression by binding to target mRNAs. miRNAs have not been comprehensively studied in recurrent ovarian cancer, yet an incurable disease. Results Using real-time RT-PCR, we obtained distinct miRNA expression profiles between primary and recurrent serous papillary ovarian adenocarcinomas (n = 6 in a subset of samples previously used in a transcriptome approach. Expression levels of top dysregulated miRNA genes, miR-223 and miR-9, were examined using TaqMan PCR in independent cohorts of fresh frozen (n = 18 and FFPE serous ovarian tumours (n = 22. Concordance was observed on TaqMan analysis for miR-223 and miR-9 between the training cohort and the independent test cohorts. Target prediction analysis for the above miRNA "recurrent metastatic signature" identified genes previously validated in our transcriptome study. Common biological pathways well characterised in ovarian cancer were shared by miR-9 and miR-223 lists of predicted target genes. We provide strong evidence that miR-9 acts as a putative tumour suppressor gene in recurrent ovarian cancer. Components of the miRNA processing machinery, such as Dicer and Drosha are not responsible for miRNA deregulation in recurrent ovarian cancer, as deluded by TaqMan and immunohistochemistry. Conclusion We propose a miRNA model for the molecular pathogenesis of recurrent ovarian cancer. Some of the differentially deregulated miRNAs identified correlate with our previous transcriptome findings. Based on integrated transcriptome and miRNA analysis, miR-9 and miR-223 can be of potential importance as biomarkers in recurrent ovarian cancer.

    Avelumab is a human anti-PD-L1 checkpoint inhibitor with clinical activity in multiple solid tumors. Here, we describe the rationale and design for JAVELIN Ovarian 200 (NCT02580058), the first randomized Phase III trial to evaluate the role of checkpoint inhibition in women with ovarian cancer. This three-arm trial is comparing avelumab administered alone or in combination with pegylated liposomal doxorubicin versus pegylated liposomal doxorubicin alone in patients with platinum-resistant/refractory recurrent ovarian, fallopian tube or peritoneal cancer. Eligible patients are not preselected based on PD-L1 expression and may have received up to three prior lines of chemotherapy for platinum-sensitive disease, but none for resistant disease. Overall survival and progression-free survival are primary end points, and secondary end points include biomarker evaluations and pharmacokinetics.

    Full Text Available Abstract Introduction Benign multicystic peritoneal mesothelioma is an extremely rare tumor that occurs mainly in women in their reproductive age. Its preoperative diagnosis and adequate treatment are quite difficult to attain. Case presentation Our patient was a 23-year-old Japanese woman who had a history of right oophorectomy and left ovarian cystectomy for an ovarian tumor at 20 years of age. The left ovarian tumor had been diagnosed on histology as a mucinous borderline tumor. Two years and nine months after the initial operation, multiple cysts were found in our patient. A laparotomy was performed and her uterus, left ovary, omentum and pelvic lymph nodes were removed due to suspicion of recurrence of the borderline tumor. A histological examination, however, revealed that the cysts were not a recurrence of the borderline tumor but rather benign multicystic peritoneal mesothelioma. There were no residual lesions and our patient was followed up with ultrasonography. She remains free from recurrence nine months after treatment. Conclusion We report a case of benign multicystic peritoneal mesothelioma mimicking recurrence of an ovarian borderline tumor. Benign multicystic peritoneal mesothelioma should be suspected when a multicystic lesion is present in the pelvis as in the case presented here, especially in patients with previous abdominal surgery.

    To explore the feasibility of implementing centering prayer in chemotherapy treatment and assess its influence on mood, spiritual well-being, and quality of life in women with recurrent ovarian cancer. Descriptive pilot study. Outpatient chemotherapy treatment suite in a large cancer center in the midwestern United States. A convenience sample of 10 women receiving outpatient chemotherapy for recurrent ovarian cancer. A centering prayer teacher led participants through three one-hour sessions over nine weeks. Data were collected prior to the first session, at the conclusion of the final session, and at three and six months after the final session. Feasibility and influence of centering prayer on mood, spiritual well-being, and quality of life. Most participants identified centering prayer as beneficial. Emotional well-being, anxiety, depression, and faith scores showed improvement. Centering prayer can potentially benefit women with recurrent ovarian cancer. Additional research is needed to assess its feasibility and effectiveness. Nurses may promote or suggest centering prayer as a feasible intervention for the psychological and spiritual adjustment of patients with recurrent ovarian cancer.

    We describe a case of a young woman with a history of an aplastic anaemia in which pelvic radiotherapy was used successfully in the management of a recurrent and inoperable endometriosis. The use of therapeutic pelvic or ovarian irradiation in endometriosis may be considered, when surgical and medical treatments have been exhausted and have failed. (authors)

    Twenty-three patients previously diagnosed as having ovarian cancer were examined with both serum tumor markers (CA 125, CA 19-9, TPA, IAP, AFP) and a pelvic CT scan. The tumor markers predict the clinical outcome more accurately than the CT scan. Further, the tumor markers showed a clear correlation with the clinical course. But in one case, however, the tumor markers were seen to reduce below the normal level from chemotherapy, while the CT scan showed a tumor mass. Thus, both, a CT scan and tumor marker assays are felt to be indispensable for detecting the recurrence of an ovarian cancer. (author)

    PURPOSE: The aim of this article is to emphasize the increased risk of developing metachronous ovarian tumors after resection of rectal cancer. METHOD AND RESULTS: We report the case of a postmenopausal female patient who, five years after anterior resection, developed a primary ovarian malignancy that invaded a rectal anastomosis and in so doing mimicked a recurrence of a Dukes A rectal cancer. To our knowledge, such an occurrence has not been described previously in the literature. CONCLUSION: This case illustrates the possible benefits of routine prophylactic oophorectomy at the time of colorectal cancer resection.

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

    Full Text Available Background. Diarrhea is a common problem in ovarian cancer patients undergoing chemotherapy and Clostridium difficile infection has been identified as a cause. The proper diagnosis and treatment of diarrhea are critical to patient care, especially to prevent the serious complications from a severe Clostridium difficile infection (CDI. Case. We present a heavily pretreated ovarian cancer patient who developed recurrent pseudomembranous colitis while receiving carboplatin chemotherapy. Despite treatment with oral metronidazole for fourteen days, the patient’s diarrhea relapsed and colonoscopy revealed extensive pseudomembranous colitis. The infection eventually resolved with the combination of oral vancomycin and metronidazole. Conclusions. Diarrhea is a common problem in patients undergoing chemotherapy for ovarian cancer. Management requires obtaining the proper diagnosis. Clostridium difficile associated pseudomembranous colitis must be part of the differential diagnosis. Treatment must be sufficient to prevent relapses of the Clostridium difficile infection to prevent serious consequences in an already vulnerable patient population.

    Conclusion: IMT alone or add-on to palliative/salvage chemotherapy for refractory/recurrent EOC achieves a substantial disease stabilizing rate without severe toxicity, which might be a potential option in selected patients. The ALC 1 month after IMT could be an early indicator to disease stabilization.

    Full Text Available Bowel perforation is a rare but well-described complication of bevacizumab, a VEGF monoclonal antibody. However, bevacizumab associated abdominal wall perforation is a more serious complication. In here, a patient with recurrent epithelial ovarian cancer developing both bowel and abdominal wall perforation after bevacizumab treatment is reported with review of the literature to point out the clinical significance of this rare complication. To our knowledge, this is the first case with bevacizumab associated abdominal wall perforation.

    Objective: This study was undertaken to evaluate the clinical contribution of positron emission tomography using {sup 18}F-fluorodeoxyglucose and integrated computer tomography (FDG-PET/CT) guided intensity-modulated radiotherapy (IMRT) for treatment of recurrent ovarian cancer. Materials and methods: Fifty-eight patients with recurrent ovarian cancer from 2003 to 2008 were retrospectively studied. In these patients, 28 received PET/CT guided IMRT (PET/CT-IMRT group), and 30 received CT guided IMRT (CT-IMRT group). Treatment plans, tumor response, toxicities and survival were evaluated. Results: Changes in GTV delineation were found in 10 (35.7%) patients based on PET-CT information compared with CT data, due to the incorporation of additional lymph node metastases and extension of the metastasis tumor. PET/CT guided IMRT improved tumor response compared to CT-IMRT group (CR: 64.3% vs. 46.7%, P = 0.021; PR: 25.0% vs. 13.3%, P = 0.036). The 3-year overall survival was significantly higher in the PET-CT/IMRT group than control (34.1% vs. 13.2%, P = 0.014). Conclusions: PET/CT guided IMRT in recurrent ovarian cancer patients improved the delineation of GTV and reduce the likelihood of geographic misses and therefore improve the clinical outcome.

    The aim of this study was to determine the effectiveness of ultrasound-guided interventional therapy in the treatment of postoperative recurrent chocolate cysts. The 198 patients enrolled in this study were divided into three groups. In group 1, the saline washing group, the cavity of the cyst was washed thoroughly with warm saline. In group 2, the ethanol short-time retention group, after washing with saline, the cyst was injected with 95% ethanol with a volume of half of the fluid aspirated from the cyst. Ten minutes later, the rest of the ethanol was aspirated. In group 3, the ethanol retention group, the procedures were the same as with the ethanol short-time retention group, except that 95% of the ethanol was retained in the cyst. An ultrasound examination was performed in the third, sixth and 12th months after therapy. The chocolate cyst cure rate was significantly higher in the ethanol retention group (96%, 66/69) than in the ethanol short-time retention group (82%, 56/68) and no case was cured in the first group (saline washing). We conclude that ultrasound-guided injection and 95% ethanol retention are an effective therapy for the treatment of postoperative recurrent chocolate cysts.

    The relationship between ABO blood groups (BG) and risk of incidence in cancers including gynecological cancers has been widely studied, showing increased incidence risk for BG A patients. As available data are inconsistent we investigated whether BG and their anti-glycan antibodies (anti-A and anti-B) have prognostic values in gynecological cancers. We retrospectively evaluated 974 patients with gynecological cancers in three cancer centers (Switzerland and Australia) between 1974 and 2014 regarding the relationships between clinico-pathological findings and the BG. Time to disease recurrence was significantly influenced by BG in patients with ovarian (n = 282) and vulvar (n = 67) cancer. BG O or B patients showed a significantly increased risk for ovarian cancer relapse compared to A, 59% and 82%, respectively (p = 0.045; HR O vs A = 1.59 (CI 1.01-2.51) and (p = 0.036; HR A vs B = 0.55 (CI 0.32-0.96). Median time to relapse for advanced stage (n = 126) ovarian cancer patients was 18.2 months for BG O and 32.2 for A (p = 0.031; HR O vs A = 2.07 (CI 1.07-4.02)). BG also significantly influenced relapse-free survival in patients with vulvar cancer (p = 0.002), with BG O tending to have increased relapse risk compared to A (p = 0.089). Blood groups hence associate with recurrence in ovarian and vulvar cancer: women with BG O seem to have a lower ovarian cancer incidence, however are more likely to relapse earlier. The significance of the BG status as a prognostic value is evident and may be helpful to oncologists in prognosticating disease outcome and selecting the appropriate therapy.

    2012-09-01

    Full Text Available Abstract Background Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Methods Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. Results The most significant differences (p  Conclusions The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome.

    Obesity may negatively influence tumor biology in women with epithelial ovarian cancers. To date, only body mass indices (BMI) determined at the time of diagnosis have correlated with clinical outcome. We hypothesized that obesity negatively affects survival throughout the disease course, and sought to determine the prognostic role of BMI at the time of secondary cytoreductive surgery (SCS) for recurrent ovarian cancer. We performed a review of patients undergoing SCS for recurrent epithelial ovarian or peritoneal cancer between 1997 and 2012. We retrospectively reviewed data which were analyzed using Fisher's exact test, Kaplan-Meier survival, and Cox regression analysis. BMI was defined according to the National Institutes of Health's categorizations. We identified 104 patients; 2 were underweight, 46 were of ideal body weight, 32 were overweight, and 24 were obese. Overall, 90 patients underwent optimal resection and BMI did not correlate with ability to perform optimal SCS (p=0.25). When examining BMI strata (underweight, ideal, overweight, and obese), we observed a statistical trend between increasing BMI and poor outcome; median survival was undetermined (greater than 50 months), 46 months, 38 months, and 34 months, respectively (p=0.04). In a multivariate analysis, BMI was an independent predictor of survival (p=0.02). In this cohort of women undergoing SCS for recurrent ovarian cancer, BMI significantly and independently correlated with overall survival. This observation suggests an effect of excess weight on tumor biology and/or response to treatment that is prevalent throughout the disease course. Copyright © 2015 Elsevier Inc.

    Treatment of Epithelial Ovarian Cancer (EOC), historically based on surgery and platinum doublet chemotherapy, is associated with high risk of relapse and poor prognosis for recurrent disease. In this landscape, the innovative treatment with PARP inhibitors (PARPis) demonstrated an outstanding activity in EOC, and is currently changing clinical practice in BRCA mutant patients. To highlight the mechanism of action, pharmacokinetics, clinical activity, indications and current strategies of development of Olaparib, Niraparib, Rucaparib, Talazoparib and Veliparib, the 5 most relevant PARPis. We performed a review on Pubmed using 'ovarian cancer' and the name of each PARPi (PARP inhibitor) discussed in the review as Medical Subject Headings (MeSH) keywords. The same search was performed on "clinicaltrial.gov" to identify ongoing clinical trials and on "google.com/patents" and "uspto.gov" for recent patents exploring PARPIs in ovarian cancer. Olaparib, Niraparib and Rucaparib are already approved for treatment of recurrent EOC and their indications are partially overlapping. Talazoparib and Veliparib are promising PARPis, but currently under investigation in early phase trials. Several studies are evaluating PARPis in monotherapy or in associations, in a wide range of settings (i.e. first line, neoadjuvant, platinum-sensitive and resistant disease). PARPis are valuable options in patients with recurrent ovarian cancer with promising activity in different stages of this disease. Further studies are required to better define optimal clinical settings, predictors of response beyond BRCA mutations and strategies to overcome secondary resistance of PARPis therapy in EOC.

    Full Text Available Recurrent clear cell ovarian carcinoma is a difficult to treat condition and early trial data has suggested a possible role for immune checkpoint inhibitors. Nivolumab is an anti-PD-1 immunotherapy that has been used in this setting. While immune related toxicity of these agents has been well described, the occurrence of immune specific neurotoxicity is thought to be rare. We present a case of severe encephalitis while on PD-1 immunotherapy for a recurrent ovarian clear cell cancer and we believe this to be the first such reported case associated with the use of PD-1 inhibitor monotherapy. In this case, a 64-year-old woman with persistent clear cell ovarian cancer on Nivolumab presented with a severe fever of unknown origin and delirium; initial imaging and diagnostic work-up suggested a neurological etiology, but with no clear source. We concluded that this was a severe case of immune related encephalitis, thought to be brought about by the anti-PD-1 immunotherapy which responded well to systemic corticosteroids and plasmapheresis and the patient able to make a full recovery. We present a summary of the case and its management as well as a review of the literature on the previously reported neurotoxicity's of PD-1 inhibitors.

    To investigate the efficacy of adenosine triphosphate (ATP)-tumor chemosensitivity assay (TCA) directed chemotherapy in patients with recurrent epithelial ovarian cancer. From August 2010 to June 2012, recurrent epithelial ovarian cancer patients were prospectively enrollmented in Cancer Hospital, Peking Union Medical College,Chinese Academy of Medical Sciences.The entry criteria are as follows: (1) Histologically proven to be epithelial ovarian cancer. (2) Patients of recurrent ovarian cancer with bidimensionally measurable tumor, or ascitic or pleural fluid for testing. (3) Karnofsky performance status > 60. (4) A life expectancy of at least more than 6 months.According to patients desires, they were assigned into two groups: assay-directed therapy group and physician's-choice therapy group, patients' clinical and pathological characteristics, response rate to chemotherapy and progression-free survival (PFS) were compared between two groups. A total of 113 patients with recurrent epithelial ovarian cancer were prospectively enrollmented to assay-directed chemotherapy (n = 56) or physician's-choice chemotherapy (n = 57).There was no difference in median age,types of recurrence, surgical-pathological stage, pathological type, tumor grade, times of recurrence, residual disease at secondary cytoreductive surgery between assay-directed group and physician's-choice group. The overall response rate (ORR) and median PFS in the ATP-TCA group was 66% (37/56) and 7 months, while the ORR in the control group was 46% (26/57, P = 0.037), the median PFS was 4 months (P = 0.040). For platinum-resistant patients, the ORR between ATP-TCA directed chemotherapy 59% (16/27) and control group 25% (7/28) were significantly different (P = 0.010), and the median PFS between two groups were also significantly different (5 months and 2 months, respectively, P = 0.003). ATP-TCA directed chemotherapy could improve ORR and PFS in patients with recurrent epithelial ovarian cancer, especially

Six months later she complained of fatigue and presented with severe anemia, and her diagnosis was hemorrhagic radiation gastritis. She was treated endoscopically, but that failed to control the bleeding, making it necessary to resect surgically. The incidence of radiation gastritis is very low because the stomach is rarely within the treated field, but it is of importance to be aware that the stomach is by no means more radioresistant than other organs.

    The poor outcome of patients with recurrent ovarian cancer constitutes a continuous challenge for decision-making in clinical practice. In this setting, molecular targets have recently been identified, and novel compounds are now available. Bevacizumab has been introduced for the treatment of patients with ovarian cancer and is, to date, the most extensively investigated targeted therapy in this setting. However, potential toxicities are associated with the use of this monoclonal antibody. These toxicities have been reported in clinical trials, and can also be observed outside of trials. As limited data is currently available regarding the safety of bevacizumab treatment in daily clinical practice, the current retrospective study was designed to evaluate this. Data from 156 patients with recurrent ovarian cancer who had received bevacizumab treatment between January 2006 and June 2009 were retrospectively identified from the institutional records of five French centers. In contrast to clinical trials, the patients in the present study were not selected and had a heterogeneous profile according to their prior medical history, lines of treatment prior to bevacizumab introduction and number of relapses. The results first confirm the effect of heavy pretreatment on the occurrence of serious and fatal adverse events in clinical practice, as previously reported for clinical trials and for other retrospective cohort studies. Importantly, the data also demonstrates, for the first time, that medical history of hypertension is an independent predictive risk factor for the development of high-grade hypertension during bevacizumab treatment. These results thus suggest that treating physicians must consider all risk factors for managing bevacizumab toxicity prior to its introduction. Such risk factors include the time of bevacizumab introduction, a patient's history of hypertension and a low incidence of pre-existing obstructive disease. PMID:26998090

    Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II) serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. The most significant differences (p < 0.01) in Loss-of-heterozygosity (LOH) were identified in two relatively small regions of chromosome 19; 8.0-8,8 Mbp (19 genes) and 51.5-53.0 Mbp (37 genes). Thus, 56 genes on chromosome 19 were potential candidate genes associated with clinical outcome. LOH at 19q (51-56 Mbp) was associated with shorter disease-free survival and was an independent prognostic factor for survival in a multivariate Cox regression analysis. In particular LOH on chromosome 19q (51-56 Mbp) was significantly (p < 0.01) associated with loss of TP53 function. The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome

    The purpose of this study is to evaluate the accuracy and clinical impact of integrated positron emission tomography (PET) and computed tomography (CT) for detection of recurrent ovarian carcinoma after cytoreductive surgery and chemotherapy. Medical records of 39 patients (age, 54.912.6 years) with previously treated ovarian cancer who underwent integrated PET/CT between April 1, 2007 and June 30, 2007 were reviewed retrospectively. F-18 fluorodeoxyglucose (FDG) PET/CT was performed for the evaluation of suspected recurrence. Imaging findings were compared with results of histological examination after surgical exploration or clinical follow-up to determine the diagnostic accuracy of PET/CT in the evaluation of disease status. The clinical impact of information provided by PET/CT on patient management was assessed on the basis of clinical follow up data concerning further diagnostic or therapeutic approach. Sixteen of the 39 patients had documented recurrence during surgical exploration or clinical follow-up. Of the 16 patients with recurrence, 14 patients showed suspected lesions on PET/CT. Twenty-three of the 39 patients had no evidence of recurrent tumor during surgical exploration or clinical follow-up, and two of the 23 patients with no recurrent tumor showed suspected lesions on PET/CT. The overall sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PET/CT were 87.5 %, 91.3 %, 89.7 %, 87.5 % and 91.3 %, respectively. PET/CT modified the diagnostic or treatment plan in 15 (38.4 %) patients, by leading to the use of previously unplanned therapeutic procedures in 10 (66.7 %) patients and the avoidance of previously planned diagnostic procedures in 5 (33.3 %) patients. Integrated FDG PET/CT has high sensitivity and specificity in the detection of recurrent ovarian cancer. Thus, it is likely to play a significant role in management of recurrent ovarian cancer

    With standard treatment of epithelial ovarian cancer (EOC), prognosis is very poor. The aim of this study is to show early and late results in patients who underwent cytoreductive surgery and intraperitoneal chemotherapy. This was a retrospective single centre study. All patients with advanced and recurrent ovarian cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) or modified early postoperative intraperitoneal chemotherapy (EPIC) were included in the study. In the period 1995-2014, 116 patients were treated, 55 with primary EOC and 61 with recurrent EOC. The mean age was 59 years (26-74). Statistically, median survival time was significantly longer in the group with primary advanced cancer of the ovary (41.3 months) compared to relapsed ovarian cancer (27.3 months). Survival for the primary EOC was 65 and 24% at 3 and 5 years, respectively. Survival for recurrent EOC was 33 and 16% at 3 and 5 years, respectively. Mortality was 1/116 (0.8%). Morbidity was 11/116 (9.5%). Peritoneal cancer index (PCI) was ≤20 in 59 (51%) patients and statistically, their average survival was significantly longer than in the group of 57 (49%) patients with PCI >20 (p = 0.014). In advanced or recurrent EOC, a curative therapeutic approach was pursued that combined optimal cytoreductive surgery and intraperitoneal chemotherapy. PCI and timing of the intervention (primary or recurrent) were the strongest independent prognostic factors.

    The study deals with the preoperative ultrasound diagnosis of ovarian endometriosis, postoperative ultrasound reassessment, laparoscopic surgical resolution of ovarian endometriosis, estimation of recurrence risk 12 months after surgery by ultrasound, reappearance of clinical symptoms (such as pain) or second-look laparoscopy, and pregnancy rate 2 years after surgery. 140 patients with en- dometriosis and infertility admitted to the Iasi "Cuza-Vodă" Clinical Hospital of Obstetrics and Gynecology between the years 2009-2011 were included in the study. The patients were divided into 2 groups: group 1-59 cases that refused in vitro fertilization procedures, did not afford in vitro fertilization (IVF) or had minimal endometriosis and young ages and thus a possibility of delaying treatment, and group 2--62 cases which underwent IVF procedures immediately after surgery. No significant differences in the chance of becoming pregnant were found between the two groups (χ2 = 2.06, p = 0.0891, 95% CI); in group 1, 11.86% pregnancies were obtained while in group 2 the pregnancy rate was 11.29%. Based on the nonparametric method of analysis of contingency tables we could estimate the odds of becoming pregnant in the study groups, obtaining an odds ratio (OR = 1.16, CI: 1.04-2.23, 95% CI). This result indicated that in group 1 the odds of becoming pregnant was not significantly higher, and the estimation was made for a confidence interval of 95%. The study had in view the assessment of pregnancies obtained in the study groups and the time interval (number of weeks) from the time of intervention until the occurrence of pregnancy. The Kaplan-Meier analysis enabled the assessment of the mean value and the median value of the number of weeks until becoming pregnant, and these values did not show significant differences (χ2 = 1.55, p = 0.212, 95% CI). For endometriosis associated with infertility, hormonal suppression does not improve fertility, and therefore surgery followed by

    Insensitivity to platinum, either through inherent or acquired resistance, is a major clinical problem in the treatment of many solid tumors. Here, we explored the therapeutic potential of diethyldithiocarbamate (DDC), pyrithione (Pyr), plumbagin (Plum), 8-hydroxyquinoline (8-HQ), clioquinol (CQ) copper complexes in a panel of cancer cell lines that differ in their sensitivity to platins (cisplatin/carboplatin) using a high-content imaging system. Our data suggest that the copper complexes were effective against both platinum sensitive (IC 50  ~ 1 μM platinum) and insensitive (IC 50  > 5 μM platinum) cell lines. Furthermore, copper complexes of DDC, Pyr and 8-HQ had greater therapeutic activity compared to the copper-free ligands in all cell lines; whereas the copper-dependent activities of Plum and CQ were cell-line specific. Four of the copper complexes (Cu(DDC) 2 , Cu(Pyr) 2 , Cu(Plum) 2 and Cu(8-HQ) 2 ) showed IC 50 values less than that of cisplatin in all tested cell lines. The complex copper DDC (Cu(DDC) 2 ) was selected for in vivo evaluation due to its low nano-molar range activity in vitro and the availability of an injectable liposomal formulation. Liposomal (Cu(DDC) 2 ) was tested in a fast-growing platinum-resistant A2780-CP ovarian xenograft model and was found to achieve a statistically significant reduction (50%; p < 0.05) in tumour size. This work supports the potential use of copper-based therapeutics to treat cancers that are insensitive to platinum drugs.

    The role of radiotherapy (RT) was largely deserted after the introduction of platinum-based chemotherapy, but still survival rates are disappointingly low. This study focuses on assessing the clinical efficacy of RT in relation to chemotherapy resistance. From October 2002 to January 2015, 44 patients were diagnosed with epithelial ovarian cancer (EOC) and treated with palliative RT for persistent or recurrent EOC. All patients received initial treatment with optimal debulking surgery and adjuvant platinum-based chemotherapy. The biologically effective dose (BED) was calculated with α/β set at 10. Ninety-four sites were treated with RT with a median BED of 50.7 Gy (range 28.0 to 79.2 Gy). The primary end-point was the in-field local control (LC) interval, defined as the time interval from the date RT was completed to the date any progressive or newly recurring disease within the RT field was detected on radiographic imaging. The median follow-up duration was 52.3 months (range 7.7 to 179.0 months). The 1-year and 2-year in-field LC rates were 66.0% and 55.0%, respectively. Comparisons of percent change of in-field tumor response showed similar distribution of responses among chemoresistant and chemosensitive tumors. On multivariate analysis of predictive factors for in-field LC analyzed by sites treated, BED ≥ 50 Gy (hazard ratio, 0.4; confidence interval, 0.2–0.9; p = 0.025) showed better outcomes. Regardless of resistance to platinum-based chemotherapy, RT can be a feasible treatment modality for patients with persistent of recurrent EOC. The specific role of RT using updated approaches needs to be reassessed.

In a placebo-controlled Phase II study of olaparib maintenance therapy (NCT00753545, health-related quality of life was measured using the Functional Assessment of Cancer Therapy – Ovarian (FACT-O questionnaire. Our objective was to generate HSUVs from the FACT-O data using published mapping algorithms. Materials and methods: Algorithms were identified from a review of the literature. Goodness-of-fit and patient characteristics were compared to select the best-performing algorithm, and this was used to generate base-case HSUVs for the intention-to-treat population of the olaparib study and for patients with breast cancer antigen mutations. Results: Four FACT – General (the core component of FACT-O mapping algorithms were identified and compared. Under the preferred algorithm, treatment-related adverse events had no statistically significant effect on HSU (P>0.05. Discontinuation of the study treatment and breast cancer antigen mutation status were both associated with a reduction in HSUVs (–0.06, P=0.0009; and –0.03, P=0.0511, respectively. The mean HSUV recorded at assessment visits was 0.786. Conclusion: FACT – General mapping generated credible HSUVs for an economic evaluation of olaparib. As reported in other studies, different algorithms may produce significantly different estimates of HSUV. For this reason, it is important to test whether the choice of a specific algorithm changes the conclusions of an economic evaluation.

    To determine the impact of survival of peritoneal versus splenic metastasis in cases submitted to splenectomy as part of cytoreductive surgery in recurrent epithelial ovarian cancer. Between January 2002 and May 2014, 28 patients were submitted to splenectomy as part of secondary, tertiary and beyond tertiary cytoreduction at the Dan Setlacec Center of Gastrointestinal Disease and Liver Transplantation, Fundeni Clinical Institute, Bucharest. Splenectomy was performed as follows: at secondary cytoreduction in 21 cases, at tertiary cytoreduction in six cases, and beyond tertiary cytoreduction in one case. An R0 resection was attempted in all cases; however, in two cases submitted to splenectomy as part of tertiary cytoreduction, R1 and R2 resection, were performed, respectively. Histopathological studies revealed the presence of peritoneal seeding in 11 cases at secondary cytoreduction and in four cases submitted to splenectomy as part of tertiary cytoreduction. Parenchymatous lesions were described in nine cases submitted to splenectomy as part of secondary cytoreduction and in two cases at tertiary cytoreduction. In a single case in which splenectomy was performed in the context of secondary cytoreduction, hilar involvement was found. Peritoneal seeding was described in the patient for whom splenectomy was performed at quaternary cytoreduction. Early postoperative mortality for the entire cohort (within 30 days) was 7.1% (death occurred in two cases submitted to splenectomy during the secondary cytoreduction). The median overall survival in patients with splenic involvement via peritoneal route was 35 months, while in cases with hematogenous splenic lesions, it was 12 months (p=0.2) at secondary cytoreduction. In the sub-group of patients submitted to splenectomy as part of tertiary cytoreduction, the median overall survival in patients with splenic involvement via peritoneal route was 21 months, while in cases with hematogenous splenic lesions it was 4 months (p=0

    Abstract Background Malignant ovarian disease is characterised by high rates of mortality due to high rates of recurrent chemoresistant disease. Anecdotal evidence indicates this may be due to chemoresistant properties of cancer stem cells (CSCs). However, our understanding of the role of CSCs in recurrent ovarian disease remains sparse. In this study we used gene microarrays and meta-analysis of our previously published microRNA (miRNA) data to assess the involvement of cancer stemness signatures in recurrent ovarian disease. Methods Microarray analysis was used to characterise early regulation events in an embryonal carcinoma (EC) model of cancer stemness. This was then compared to our previously published microarray data from a study of primary versus recurrent ovarian disease. In parallel, meta-analysis was used to identify cancer stemness miRNA signatures in tumor patient samples. Results Microarray analysis demonstrated a 90% difference between gene expression events involved in early regulation of differentiation in murine EC (mEC) and embryonic stem (mES) cells. This contrasts the known parallels between mEC and mES cells in the undifferentiated and well-differentiated states. Genelist comparisons identified a cancer stemness signature set of genes in primary versus recurrent data, a subset of which are known p53-p21 regulators. This signature is present in primary and recurrent or in primary alone but essentially never in recurrent tumors specifically. Meta-analysis of miRNA expression showed a much stronger cancer stemness signature within tumor samples. This miRNA signature again related to p53-p21 regulation and was expressed prominently in recurrent tumors. Our data indicate that the regulation of p53-p21 in ovarian cancer involves, at least partially, a cancer stemness component. Conclusion We present a p53-p21 cancer stemness signature model for ovarian cancer. We propose that this may, at least partially, differentially regulate the p53-p21

    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. PMID:27932523

    Full Text Available PURPOSE: Tumor-infiltrating lymphocytes (TILs have an established impact on the prognosis of high-grade serous ovarian carcinoma (HGSOC, however, their role in recurrent ovarian cancer is largely unknown. We therefore systematically investigated TIL densities and MHC class I and II (MHC1, 2 expression in the progression of HGSOC. EXPERIMENTAL DESIGN: CD3+, CD4+, CD8+ TILs and MHC1, 2 expression were evaluated by immunohistochemistry on tissue microarrays in 113 paired primary and recurrent HGSOC. TILs were quantified by image analysis. All patients had been included to the EU-funded OCTIPS FP7 project. RESULTS: CD3+, CD4+, CD8+ TILs and MHC1 and MHC2 expression showed significant correlations between primary and recurrent tumor levels (Spearman rho 0.427, 0.533, 0.361, 0.456, 0.526 respectively; P<.0001 each. Paired testing revealed higher CD4+ densities and MHC1 expression in recurrent tumors (Wilcoxon P=.034 and P=.018. There was also a shift towards higher CD3+ TILs levels in recurrent carcinomas when analyzing platinum-sensitive tumors only (Wilcoxon P=.026 and in pairs with recurrent tumor tissue from first relapse only (Wilcoxon P=.031. High MHC2 expression was the only parameter to be significantly linked to prolonged progression-free survival after first relapse (PFS2, log-rank P=.012. CONCLUSIONS: This is the first study that analyzed the development of TILs density and MHC expression in paired primary and recurrent HGSOC. The level of the antitumoral immune response in recurrent tumors was clearly dependent on the one in the primary tumor. Our data contribute to the understanding of temporal heterogeneity of HGSOC immune microenvironment and have implications for selection of samples for biomarker testing in the setting of immune-targeting therapeutics.

Lipo-Dox utilizes a different liposomal particle than Doxil and demonstrates different pharmacokinetic properties. Its use has never been evaluated in a North American population. The objective of this study was to evaluate the efficacy and tolerability of Lipo-Dox at Magee-Womens Hospital, University of Pittsburgh Medical Center, for patients with recurrent epithelial ovarian cancer who were treated during the Doxil shortage. Methods: Patients treated with Lipo-Dox from January 2012 to December 2012 were identified retrospectively. Disease response was defined radiographically by RECIST (Response Evaluation Criteria in Solid Tumors or biochemically by CA-125 level if measurable disease was not present. Survival was defined from the start date of Lipo-Dox until the date of progression or death. Toxicity was assessed by the Gynecologic Oncology Group common toxicity criteria. Results: Eighteen patients with recurrent epithelial ovarian cancer who received Lipo-Dox were identified. These patients had a median of three prior treatment regimens. The median number of Lipo-Dox cycles given was 3.5 (range 1–8. No patients had a complete or partial response. Two patients had stable disease over a mean follow-up of 144.5 days. Fourteen patients had progressive disease, with a median time to progression of 82 days. Progression was based on CA-125 in four patients and RECIST in the remainder. Nine patients died from the disease. Conclusion: Although this represents a small, pretreated population, there were no clinical

    Our group previously reported that tumour-specific expression of the rate-limiting enzyme in the mevalonate pathway, 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoAR) is associated with more favourable tumour parameters and a good prognosis in breast cancer. In the present study, the prognostic value of HMG-CoAR expression was examined in tumours from a cohort of patients with primary epithelial ovarian cancer. HMG-CoAR expression was assessed using immunohistochemistry (IHC) on tissue microarrays (TMA) consisting of 76 ovarian cancer cases, analysed using automated algorithms to develop a quantitative scoring model. Kaplan Meier analysis and Cox proportional hazards modelling were used to estimate the risk of recurrence free survival (RFS). Seventy-two tumours were suitable for analysis. Cytoplasmic HMG-CoAR expression was present in 65% (n = 46) of tumours. No relationship was seen between HMG-CoAR and age, histological subtype, grade, disease stage, estrogen receptor or Ki-67 status. Patients with tumours expressing HMG-CoAR had a significantly prolonged RFS (p = 0.012). Multivariate Cox regression analysis revealed that HMG-CoAR expression was an independent predictor of improved RFS (RR = 0.49, 95% CI (0.25-0.93); p = 0.03) when adjusted for established prognostic factors such as residual disease, tumour stage and grade. HMG-CoAR expression is an independent predictor of prolonged RFS in primary ovarian cancer. As HMG-CoAR inhibitors, also known as statins, have demonstrated anti-neoplastic effects in vitro, further studies are required to evaluate HMG-CoAR expression as a surrogate marker of response to statin treatment, especially in conjunction with current chemotherapeutic regimens

    Metabolic tumour volume (MTV) and total lesion glycolysis (TLG) from (18)F-FDG PET/CT are emerging prognostic biomarkers in various solid neoplasms. These volumetric parameters and the SUVmax have shown to be useful criteria for disease prognostication in preoperative and post-treatment epithelial ovarian cancer (EOC) patients. The purpose of this study was to evaluate the utility of (18)F-FDG PET/CT measurements to predict survival in patients with recurrent EOC. Twenty-six patients with EOC who underwent a total of 31 (18)F-FDG PET/CT studies for suspected recurrence were retrospectively included. SUVmax and volumetric parameters whole-body MTV (wbMTV) and whole-body TLG (wbTLG) with a threshold of 40% and 50% of the SUVmax were obtained. Correlation between PET parameters and progression-free survival (PFS) and the survival analysis of prognostic factors were calculated. Serous cancer was the most common histological subtype (76.9%). The median PFS was 12.5 months (range 10.7-20.6 months). Volumetric parameters showed moderate inverse correlation with PFS but there was no significant correlation in the case of SUVmax. The correlation was stronger for first recurrences. By Kaplan-Meier analysis and log-rank test, wbMTV 40%, wbMTV 50% and wbTLG 50% correlated with PFS. However, SUVmax and wbTLG 40% were not statistically significant predictors for PFS. Volumetric parameters wbMTV and wbTLG 50% measured by (18)F-FDG PET/CT appear to be useful prognostic predictors of outcome and may provide valuable information to individualize treatment strategies in patients with recurrent EOC.

    This meta-analysis aimed to evaluate the prognosis and recurrence of apparent early-stage ovarian tumors treated with laparoscopy compared with laparotomy. Clinical studies published in English were retrieved from the computerized databases Medline and Embase. A meta-analysis was performed to investigate the differences in the efficacy and safety of laparoscopy versus laparotomy in terms of postoperative complications, lengths of hospital stay, recurrence rates, and disease-free survival times using the random effects model. The studies were independently reviewed by two investigators. Data from the eligible studies were extracted, and the meta-analysis was performed using the Comprehensive Meta-Analysis program, version 2 (CMA-2; Biostat, Englewood, NJ, USA). A total of 8 studies were included in the analysis. The results showed that laparoscopic surgery was significantly associated with lower rates of complications (OR = 0.433, P = 0.019) and shorter postoperative hospital stays (weighted mean difference [WMD] = −0.974, P < 0.001). There was no significant difference in the rates of recurrence (OR = 0.707, P = 0.521) between patients with apparent early-stage ovarian tumors who were treated using laparoscopy and those who underwent laparotomy. No publication bias was detected. Laparoscopic surgery shows favorable prognostic outcomes in terms of postoperative complication rates and postoperative hospital stay durations. Further studies with longer follow-up periods are required to confirm recurrence and survival outcomes after laparoscopic surgery in patients with apparent early-stage ovarian tumors

    Ovarian carcinoma (OC) is the most lethal of the gynecological malignancies, often presenting at an advanced stage. Treatment is hampered by high levels of drug resistance. The taxanes are microtubule stabilizing agents, used as first-line agents in the treatment of OC that exert their apoptotic effects through the spindle assembly checkpoint. BUB1-related protein kinase (BUBR1) and mitotic arrest deficient 2 (MAD2), essential spindle assembly checkpoint components, play a key role in response to taxanes. BUBR1, MAD2, and Ki-67 were assessed on an OC tissue microarray platform representing 72 OC tumors of varying histologic subtypes. Sixty-one of these patients received paclitaxel and platinum agents combined; 11 received platinum alone. Overall survival was available for all 72 patients, whereas recurrence-free survival (RFS) was available for 66 patients. Increased BUBR1 expression was seen in serous carcinomas, compared with other histologies (P = .03). Increased BUBR1 was significantly associated with tumors of advanced stage (P = .05). Increased MAD2 and BUBR1 expression also correlated with increased cellular proliferation (P < .0002 and P = .02, respectively). Reduced MAD2 nuclear intensity was associated with a shorter RFS (P = .03), in ovarian tumors of differing histologic subtype (n = 66). In this subgroup, for those women who received paclitaxel and platinum agents combined (n = 57), reduced MAD2 intensity also identified women with a shorter RFS (P < .007). For the entire cohort of patients, irrespective of histologic subtype or treatment, MAD2 nuclear intensity retained independent significance in a multivariate model, with tumors showing reduced nuclear MAD2 intensity identifying patients with a poorer RFS (P = .05).

    Optimal cytoreduction is one the main factors improving survival outcomes in patients affected by ovarian cancer (OC). It is estimated that approximately 40% of OC patients have gross disease located on the diaphragm. However, no mature data evaluating outcomes of surgical techniques for the management of diaphragmatic carcinosis exist. In the present study, we aimed to estimate surgery-related morbidity of different surgical techniques for diaphragmatic cytoreduction in advanced or recurrent OC. PubMed (MEDLINE), Web of Science, and Clincaltrials.gov databases were searched for records estimating outcomes of diaphragmatic peritoneal stripping (DPS) or diaphragmatic full-thickness resection (DFTR) for OC. The meta-analysis was performed using the Cochrane Review software. For the final analysis, 5 articles were available, including 272 patients. Diaphragmatic peritoneal stripping and DFTR were performed in 197 patients (72%) and 75 patients (28%), respectively. Pooled analysis suggested that the estimated pleural effusion rate was 43% and 51% after DPS and DFTR, respectively. The need for pleural punctures or chest tube placement was 4% and 9% after DPS and DFTR, respectively. The rate of postoperative pneumothorax (4% vs 9%; odds ratio, 0.31; 95% confidence interval, 0.05-2.08) and subdiaphragmatic abscess (3% vs 3%; odds ratio, 0.45; 95% confidence interval, 0.09-2.31) were similar after the execution of DPS and DFTR. Diaphragmatic surgery is a crucial step during cytoreduction for advanced or recurrent OC. Obviously, the choice to perform DPS or DFTR depends on the infiltration of the diaphragmatic muscle or not. Both the procedures are associated with a low pulmonary complication and chest tube placement rates.

    The aim of this study was to evaluate the clinical value of FDG PET/CT in patients with suspected ovarian cancer recurrence as compared with diagnostic CT, and to assess the impact of the results of FDG PET/CT on treatment planning. Included in this retrospective study were 60 patients with suspected recurrent ovarian cancer who had previously undergone primary debulking surgery and had been treated with adjuvant chemotherapy. Diagnostic CT and FDG PET/CT imaging were performed for all patients as clinically indicated. The changes in the clinical management of patients according to the results of FDG PET/CT were also analysed. FDG PET/CT was performed in 21 patients with a previously negative or indeterminate diagnostic CT scan, but an elevated CA-125 level, and provided a sensitivity of 95% in the detection of recurrent disease. FDG PET/CT revealed recurrent disease in 19 patients. In 17 of 60 patients, the indication for FDG PET/CT was an elevated CA-125 level and an abnormal diagnostic CT scan to localize accurately the extent of disease. FDG PET/CT scans correctly identified recurrent disease in 16 of the 17 patients, a sensitivity of 94.1%. Moreover, FDG PET/CT was performed in 18 patients with clinical symptoms of ovarian cancer recurrence, an abnormal diagnostic CT scan, but a normal CA-125 level. In this setting, FDG PET/CT correctly confirmed recurrent disease in seven patients providing a sensitivity of 100% in determining recurrence. In four patients, FDG PET/CT was carried out for the assessment of treatment response. Three of four scans were classified as true-negative indicating a complete response. In the other patient, FDG PET/CT identified progression of disease. In total, 45 (75%) of the 60 patients had recurrent disease, in 14 (31.1%) documented by histopathology and in 31 (68.9%) on clinical follow-up, while 15 (25%) had no evidence of recurrent disease.

    The prognosis of patients with recurrent, platinum-resistant epithelial ovarian cancer (EOC) is poor. There is no standard treatment available. Emerging evidence suggests a major role for antiangiogenic treatment modalities in EOC, in particular in combination with the metronomic application of low dose chemotherapy. The novel, investigational oral antiangiogenic agent pazopanib targeting vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR) and c-kit is currently being studied in different tumour types and is already used as first line therapy in recurrent renal cell carcinoma. A combined therapy consisting of pazopanib and metronomic oral cyclophosphamide may offer a well-tolerable treatment option to patients with recurrent, pretreated EOC. This study is designed as a multicenter phase I/II trial evaluating the optimal dose for pazopanib (phase I) as well as activity and tolerability of a combination regimen consisting of pazopanib and metronomic cyclophosphamide in the palliative treatment of patients with recurrent, platinum-resistant, pre-treated ovarian cancer (phase II). The patient population includes patients with histologically or cytologically confirmed diagnosis of EOC, cancer of the fallopian tube or peritoneal cancer which is platinumresistant or -refractory. Patients must have measurable disease according to RECIST criteria and must have failed available standard chemotherapy. Primary objectives are determination of the optimal doses for pazopanib (phase I) and the overall response rate according to RECIST criteria (phase II). Secondary objectives are time to progression, overall survival, safety and tolerability. The treatment duration is until disease progression or intolerability of study drug regimen (with a maximum of 13 cycles up to 52 weeks per subject). The current phase I/II trial shall clarify the potential of the multitargeting antiangiogenic tyrosinkinaseinhibitor GW 786034 (pazopanib) in

    Chemoresistance is a major hurdle in the management of patients with epithelial ovarian cancer and is responsible for its high mortality. Studies have shown that chemoresistance is due to the presence of a subgroup of cancer cells with stemness properties and a high capacity for tumor repair. We have developed a library of super-benzopyran analogues to generate potent compounds that can induce cell death in chemoresistant cancer stem cells. TRX-E-002-1 is identified as the most potent analogue and can induce cell death in all chemoresistant CD44(+)/MyD88(+) ovarian cancer stem cells tested (IC50 = 50 nmol/L). TRX-E-002-1 is also potent against spheroid cultures formed from cancer stem cells, chemosensitive CD44(-)/MyD88(-) ovarian cancer cells, and heterogeneous cultures of ovarian cancer cells. Cell death was associated with the phosphorylation and increased levels of c-Jun and induction of caspases. In vivo, TRX-E-002-1 given as daily intraperitoneal monotherapy at 100 mg/kg significantly decreased intraperitoneal tumor burden compared with vehicle control. When given in combination with cisplatin, animals receiving the combination of cisplatin and TRX-E-002-1 showed decreased tumor burden compared with each monotherapy. Finally, TRX-E-002-1 given as maintenance treatment after paclitaxel significantly delayed disease recurrence. Our results suggest that TRX-E-002-1 may fill the current need for better therapeutic options in the control and management of recurrent ovarian cancer and may help improve patient survival.

    To compare the incidences of symptom recurrence and permanent amenorrhea following uterine artery embolization (UAE) for symptomatic fibroid tumors in patients with type I and II utero-ovarian anastomoses (UOAs) with versus without ovarian artery embolization (OAE). A retrospective, institutional review board-approved study of 99 women who underwent UAE for symptomatic fibroid tumors from April 2005 to October 2010 was conducted to identify patients who had type I or II UOAs at the time of UAE. Based on the embolization technique, patients were categorized into standard (ie, UAE only), combined (ie, UAE and OAE), and control (patients without UOAs who underwent UAE) groups. Data collected included patient characteristics, procedural technique and findings, symptom recurrence, secondary interventions, and permanent amenorrhea. Statistical analysis was performed with the Fisher exact test, with significance reached at P amenorrhea after procedures (follow-up, 561 d ± 490). There was a significantly higher incidence of symptom recurrence in the standard group compared with the control group (P = .01), with no differences between combined and control groups (P = 1). There were no statistical differences in permanent amenorrhea rates in the groups studied, with significantly higher symptom recurrence rates observed when OAE was not performed in the setting of UOA.

    The aim of this study was to compare prospectively the accuracy of whole-body positron emission tomography (PET), CT and MRI in diagnosing primary and recurrent ovarian cancer. Nineteen patients (age range 23-76 years) were recruited with suspicious ovarian lesions at presentation (n = 8) or follow-up for recurrence (n = 11). All patients were scheduled for laparotomy and histological confirmation. Whole-body PET with FDG, contrast-enhanced spiral CT of the abdomen, including the pelvis, and MRI of the entire abdomen were performed. Each imaging study was evaluated separately. Imaging findings were correlated with histopathological diagnosis. The sensitivity, specificity and accuracy for lesion characterization in patients with suspicious ovarian lesions (n = 7) were, respectively: 100, 67 and 86 % for PET; 100, 67 and 86 % for CT; and 100, 100 and 100 % for MRI. For the diagnosis of recurrent disease (n = 10), PET had a sensitivity of 100 %, specificity of 50 % and accuracy of 90 %. The PET technique was the only technique which correctly identified a single transverse colon metastasis. Results for CT were 40, 50 and 43 %, and for MRI 86, 100 and 89 %, respectively. No statistically significant difference was seen. Neither FDG PET nor CT nor MRI can replace surgery in the detection of microscopic peritoneal disease. No statistically significant difference was observed for the investigated imaging modalities with regard to lesion characterization or detection of recurrent disease; thus, the methods are permissible alternatives. The PET technique, however, has the drawback of less accurate spatial assignment of small lesions compared with CT and MRI. (orig.)

    To assess the impact of FDG PET-CT on the management of patients with suspected recurrent ovarian cancer and to determine the incremental information provided by PET-CT. This was a prospective, multi-centre, cohort study. Ninety women (mean age 59.9 years; age range 35-85 years) with a previous history of treated epithelial ovarian carcinoma and suspected recurrence based on elevated CA-125, anatomical imaging or clinical symptoms were studied with FDG PET-CT across two States. Referring doctors were asked to specify a management plan pre-PET, if management was altered after PET-CT and, the impact (rated - none, low, medium, high) of PET-CT on patient management. The pre-PET management plan could include radiotherapy, chemotherapy, surgery, and 'other' including observation. Patients were followed at 6 and 12 months and clinical status, evidence of recurrence and progression were recorded. Patients were referred by 34 individual specialists. At least 168 additional sites of disease in 61 patients (68%), not identified by conventional imaging were identified by PET-CT. In 77% the additional lesions were located below the diaphragm and most were nodal or peritoneal. PET-CT affected management in 60% (49% high, 11% medium impact). Patients where more disease was detected with PET-CT were more likely to progress in the following 12 months. For women with previously treated ovarian carcinoma with recurrent disease, PET-CT can: a) alter management in close to 60% of patients, b) detect more sites of disease than abdominal and pelvic CT, c) is superior in the detection of nodal, peritoneal and subcapsular liver disease and d) offers the opportunity for technology replacement in this setting.

    Full Text Available OBJECTIVE: Aldehyde dehydrogenase (ALDH expressing cells have been characterized as possessing stem cell-like properties. We evaluated ALDH+ ovarian cancer stem cell-like properties and their role in platinum resistance. METHODS: Isogenic ovarian cancer cell lines for platinum sensitivity (A2780 and platinum resistant (A2780/CP70 as well as ascites from ovarian cancer patients were analyzed for ALDH+ by flow cytometry to determine its association to platinum resistance, recurrence and survival. A stable shRNA knockdown model for ALDH1A1 was utilized to determine its effect on cancer stem cell-like properties, cell cycle checkpoints, and DNA repair mediators. RESULTS: ALDH status directly correlated to platinum resistance in primary ovarian cancer samples obtained from ascites. Patients with ALDHHIGH displayed significantly lower progression free survival than the patients with ALDHLOW cells (9 vs. 3 months, respectively p<0.01. ALDH1A1-knockdown significantly attenuated clonogenic potential, PARP-1 protein levels, and reversed inherent platinum resistance. ALDH1A1-knockdown resulted in dramatic decrease of KLF4 and p21 protein levels thereby leading to S and G2 phase accumulation of cells. Increases in S and G2 cells demonstrated increased expression of replication stress associated Fanconi Anemia DNA repair proteins (FANCD2, FANCJ and replication checkpoint (pS317 Chk1 were affected. ALDH1A1-knockdown induced DNA damage, evidenced by robust induction of γ-H2AX and BAX mediated apoptosis, with significant increases in BRCA1 expression, suggesting ALDH1A1-dependent regulation of cell cycle checkpoints and DNA repair networks in ovarian cancer stem-like cells. CONCLUSION: This data suggests that ovarian cancer cells expressing ALDH1A1 may maintain platinum resistance by altered regulation of cell cycle checkpoint and DNA repair network signaling.

    AURELIA, a randomized phase III trial of adding bevacizumab (B) to single agent chemotherapy (CT) for the treatment of platinum-resistant recurrent ovarian cancer, demonstrated improved progression free survival (PFS) in the B+CT arm compared to CT alone. We aimed to evaluate the cost effectiveness of adding B to CT in the treatment of platinum-resistant recurrent ovarian cancer. A decision tree model was constructed to evaluate the cost effectiveness of adding bevacizumab (B) to single agent chemotherapy (CT) based on the arms of the AURELIA trial. Costs, quality-adjusted life years (QALYs), and progression free survival (PFS) were modeled over fifteen months. Model inputs were extracted from published literature and public sources. Incremental cost effectiveness ratios (ICERs) per QALY gained and ICERs per progression free life year saved (PF-LYS) were calculated. One-way sensitivity analyses were performed to evaluate the robustness of results. The ICER associated with B+CT is $410,455 per QALY gained and $217,080 per PF-LYS. At a willingness to pay (WTP) threshold of $50,000/QALY, adding B to single agent CT is not cost effective for this patient population. Even at a WTP threshold of $100,000/QALY, B+CT is not cost effective. These findings are robust to sensitivity analyses. Despite gains in QALY and PFS, the addition of B to single agent CT for treatment of platinum-resistant recurrent ovarian cancer is not cost effective. Benefits, risks, and costs associated with treatment should be taken into consideration when prescribing chemotherapy for this patient population. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Purpose In spite of increased rates of complete response to initial chemotherapy, most patients with advanced ovarian cancer relapse and succumb to progressive disease. Rationale Genetically reprogrammed, patient-derived chimeric antigen receptor (CAR-T lymphocytes with the ability to recognize predefined surface antigens with high specificity in a non-MHC restricted manner have shown increasing anti-tumor efficacy in preclinical and clinical studies. Folate receptor-α (FRα is an ovarian cancer-specific tumor target; however, it is expressed at low levels in certain organs with risk for toxicity. Design Here we propose a phase I study testing the feasibility, safety and preliminary activity of FRα-redirected CAR-T cells bearing the CD137 (4-1BB costimulatory domain, administered after lymphodepletion for the treatment of recurrent ovarian cancer. A novel trial design is proposed that maximizes safety features. Innovation This design involves an initial accelerated dose escalation phase of FR-α CAR-T cells followed by a standard 3 + 3 escalation phase. A split-dose approach is proposed to mitigate acute adverse events. Furthermore, infusion of bulk untransduced autologous peripheral blood lymphocytes (PBL is proposed two days after CAR-T cell infusion at the lower dose levels of CAR-T cells, to suppress excessive expansion of CAR-T cells in vivo and mitigate toxicity.

    Platinum based drugs are the cornerstone of chemotherapy for ovarian cancer, however the development of chemoresistance hinders its success. IL-8 is involved in regulating several pro-survival pathways in cancer. We studied the expression of IL-8 and IL-8 receptors in platinum sensitive and resistant cell lines. Using qRT-PCR and immunohistochemistry, both platinum sensitive (PEA1, PEO14) and resistant (PEA2, PEO23) show increased expression of IL-8 and IL-8 receptors. IL-8RA shows nuclear and cytoplasmic expression, whilst IL-8RB is present solely in the cytoplasm. Knockdown of IL-8 increased sensitivity to cisplatin in platinum sensitive and reversed platinum resistance in resistant cell lines, decreased the expression of anti-apoptotic Bcl-2 and decreased inhibitory phosphorylation of pro-apoptotic Bad. IL-8 receptor antagonist treatment also enhanced platinum sensitivity. Nuclear localisation of IL-8RA was only detected in platinum resistant tumours. Inhibition of IL-8 signalling can enhance response in platinum sensitive and resistant disease. Nuclear IL-8RA may have potential as a biomarker of resistant disease.

    Full Text Available Ilaria Colombo, Stephanie Lheureux, Amit Manulal Oza Division of Medical Oncology and Hematology, Princess Margaret Cancer Centre, University Health Network, Toronto, ON, Canada Abstract: Rucaparib is a potent small-molecule inhibitor of poly (ADP-ribose polymerase (PARP proteins (PARP-1, PARP-2 and PARP-3 that play an important role in repairing DNA damage and maintaining genomic stability. Tumors with mutations in BRCA1/2 or other homologous recombination deficiency (HRD genes are particularly sensitive to PARP inhibitors because of “synthetic lethality”, whereby a therapeutic agent can take advantage of an intrinsic weakness in DNA repair. Rucaparib has been investigated in several preclinical and clinical studies showing promising activity in BRCA-mutant and BRCA–wild-type epithelial ovarian cancers (EOCs. Dose-escalation Phase I studies have established the recommended Phase II dose to be 600 mg twice a day for oral rucaparib. Phase II and III studies have defined its role as treatment for BRCA-mutant recurrent high-grade EOC and as maintenance treatment for platinum-sensitive relapsed EOC following response to platinum-based chemotherapy. Genomic loss of heterozygosity has also been investigated as a potential signature of HRD and as a potential predictive biomarker of response. Treatment-induced adverse events (AEs have been observed in almost all patients treated with rucaparib, but mainly lower grade; with the most common being nausea, vomiting, asthenia/fatigue, anemia and transient transaminitis. The majority of AEs occurred early in treatment, were transient and have been easily managed with supportive treatment, dose interruption or discontinuation. This review will analyze the results of clinical trials investigating efficacy and safety of rucaparib in patients with ovarian cancer.

    Traditional prognostic factors in epithelial ovarian cancer (EOC) are inadequate in predicting recurrence and long-term prognosis, but genome-wide cancer research has recently provided multiple potentially useful biomarkers. The gene codifying for Mammaglobin B (MGB-2) has been selected from our previous microarray analysis performed on 19 serous papillary epithelial ovarian cancers and its expression has been further investigated on multiple histological subtypes, both at mRNA and protein level. Since, to date, there is no information available on the prognostic significance of MGB-2 expression in cancer, the aim of this study was to determine its prognostic potential on survival in a large cohort of well-characterized EOC patients. MGB-2 expression was evaluated by quantitative real time-PCR in fresh-frozen tissue biopsies and was validated by immunohistochemistry in matched formalin fixed-paraffin embedded tissue samples derived from a total of 106 EOC patients and 27 controls. MGB-2 expression was then associated with the clinicopathologic features of the tumors and was correlated with clinical outcome. MGB-2 expression was found significantly elevated in EOC compared to normal ovarian controls, both at mRNA and protein level. A good correlation was detected between MGB-2 expression data obtained by the two different techniques. MGB-2 expressing tumors were significantly associated with several clinicopathologic characteristics defining a less aggressive tumor behavior. Univariate survival analysis revealed a decreased risk for cancer-related death, recurrence and disease progression in MGB-2-expressing patients (p < 0.05). Moreover, multivariate analysis indicated that high expression levels of MGB-2 transcript (HR = 0.25, 95%, 0.08–0.75, p = 0.014) as well as positive immunostaining for the protein (HR = 0.41, 95%CI, 0.17–0.99, p = 0.048) had an independent prognostic value for disease-free survival. This is the first report documenting that MGB-2

    We present ultrasonography and computed tomography (CT) findings of a case of recurrent ovarian steroid cell tumor presenting with peritoneal seeding in a 45-year-old woman. On abdominal ultrasonography, there were multiple hypoechoic round masses in the peritoneal cavity including the perihepatic area. Contrast-enhanced ultrasonography showed intense homogenous enhancement on the arterial phase and delayed prolonged enhancement of the masses. CT revealed multiple peritoneal solid masses with strong enhancement. Five years ago, the patient had been diagnosed with a steroid cell tumor of the left ovary. At that time, the CT showed a well-enhancing, lobulating, large solid mass at the left adnexa. Imaging findings of the peritoneal masses suggested peritoneal seeding from the preexisting ovarian steroid cell tumor. For treatment of the metastatic lesions in the perihepatic area, ultrasonography-guided radiofrequency ablation (RFA) was performed, and debulking surgery for the peritoneal masses was done. Six months later, complete ablation of the perihepatic metastases by RFA and a marked decrease in the peritoneal metastases by surgery were found on the follow-up CT.

    Angiogenesis is important for epithelial ovarian cancer (EOC) growth, and blocking angiogenesis can lead to EOC regression. Cediranib is an oral tyrosine kinase inhibitor (TKI) of vascular endothelial growth factor receptor (VEGFR) -1, VEGFR-2, VEGFR-3, and c-kit. We conducted a phase II study of cediranib for recurrent EOC or peritoneal or fallopian tube cancer; cediranib was administered as a daily oral dose, and the original dose was 45 mg daily. Because of toxicities observed in the first 11 patients, the dose was lowered to 30 mg. Eligibility included 16 weeks, or CA-125 nonprogression > 16 weeks), which was the primary end point, was 30%; eight patients (17%; 95% CI, 7.6% to 30.8%) had a PR, six patients (13%; 95% CI, 4.8% to 25.7%) had SD, and there were no CRs. Eleven patients (23%) were removed from study because of toxicities before two cycles. Grade 3 toxicities (> 20% of patients) included hypertension (46%), fatigue (24%), and diarrhea (13%). Grade 2 hypothyroidism occurred in 43% of patients. Grade 4 toxicities included CNS hemorrhage (n = 1), hypertriglyceridemia/hypercholesterolemia/elevated lipase (n = 1), and dehydration/elevated creatinine (n = 1). No bowel perforations or fistulas occurred. Median PFS was 5.2 months, and median OS has not been reached; median follow-up time is 10.7 months. Cediranib has activity in recurrent EOC, tubal cancer, and peritoneal cancer with predictable toxicities observed with other TKIs.

    Background and Purpose: The follow-up of epithelial ovarian cancer (OCA) consists of clinical investigation, sonography, and tumor markers (TMs), especially CA 125. If tumor recurrence is suspected, other imaging modalities including positron emission tomography (PET) with {sup 18}F-deoxyglucose (FDG) are often used. While there is still no consensus about the method of choice and the timing of its application, this study aims to find a TM threshold at which a PET would be appropriate. Material and Methods: A total of 90 PET studies and the associated CA 125 values (normal value <35 U/ml) were available in 71 patients during the follow-up afte primary therapy for OCA. In 48 studies a CEA value (normal value <3 ng/ml) was also available. The results of PET imaging were related to the level of TM increase. Results: In 23/90 studies the PET scan was normal. These patients had a median CA 125 of 13.3 U/ml (range 4.2-168 U/ml). In 67/90 studies the PET indicated a potential recurrence of OCA and the median CA 125 was 166.7 U/ml (range 13.3-4,060 U/ml). The TM levels were significantly different (p<0.001, U-test). With one exception, there were no normal PET scans above CA 125 levels of 30 U/ml; between 20 and 30 U/ml PET was positive in 4/7 studies. Conclusion: In suspected recurrence of OCA, if imaging modalities are to be used, an FDG PET may be considered. Since the costs of this investigation are high, it should be restricted to clinical situations where it is likely to be most effective. In this study a PET indication is worthwhile at CA 125 levels of approximately 30 U/ml. (orig.)

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

    Poly(ADP-ribose) polymerase (PARP)-inhibitors and anti-angiogenics have activity in recurrent ovarian and breast cancer; however, the effect of combined therapy against PARP and angiogenesis in this population has not been reported. We investigated the toxicities and recommended phase 2 dosing (RP2D) of the combination of cediranib, a multitargeted inhibitor of vascular endothelial growth factor receptor (VEGFR)-1/2/3 and olaparib, a PARP-inhibitor (NCT01116648). Cediranib tablets once daily and olaparib capsules twice daily were administered orally in a standard 3+3 dose escalation design. Patients with recurrent ovarian or metastatic triple-negative breast cancer were eligible. Patients had measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or met Gynecologic Cancer InterGroup (GCIG) CA125 criteria. No prior PARP-inhibitors or anti-angiogenics in the recurrent setting were allowed. 28 patients (20 ovarian, 8 breast) enrolled to 4 dose levels. 2 dose limiting toxicities (DLTs) (1 grade 4 neutropenia ≥ 4 days; 1 grade 4 thrombocytopenia) occurred at the highest dose level (cediranib 30 mg daily; olaparib 400 mg twice daily [BID]). The RP2D was cediranib 30 mg daily and olaparib 200 mg BID. Grade 3 or higher toxicities occurred in 75% of patients, and included grade 3 hypertension (25%) and grade 3 fatigue (18%). One grade 3 bowel obstruction occurred. The overall response rate (ORR) in the 18 RECIST-evaluable ovarian cancer patients was 44%, with a clinical benefit rate (ORR plus stable disease (SD) > 24 weeks) of 61%. None of the seven evaluable breast cancer patients achieved clinical response; two patients had stable disease for > 24 weeks. The combination of cediranib and olaparib has haematologic DLTs and anticipated class toxicities, with promising evidence of activity in ovarian cancer patients. Copyright © 2013 Elsevier Ltd.

The patient was a 54-year-old woman with stage IIIC recurrent ovarian serous adenocarcinoma (grade 3. Computed tomography (CT revealed that no evidence of ascites, multiple intraperitoneal dissemination, or intrapelvic lymph node metastases was present. The absence of bowel obstruction and disseminated lesions involving the intestinal tract was confirmed by CT. Performance status was 0, and a blood test also indicated preservation of major organ function. In our hospital, weekly paclitaxel plus bevacizumab therapy (paclitaxel at 80 mg/m2 on days 1, 8, and 15; bevacizumab at 15/mg/kg on day 1 and every 21 days thereafter was started. Eight cycles were administered, with no signs of gastrointestinal perforation, and the antitumor effect was evaluated as a complete response. The observed adverse events included grade 1 hyponatremia and grade 1 hypochloremia, and there was one grade 1 sensory peripheral neuropathy. These adverse events neither delayed treatment nor necessitated any dosage reductions. This case suggests that bevacizumab can be safely administered even to patients with recurrent ovarian cancer who have received three or more prior chemotherapy regimens if there are neither symptoms of bowel obstruction nor lesions suggestive of intestinal invasion on diagnostic imaging.

    We aimed to assess the role of positron emission tomography using fluorodeoxyglucose (FDG-PET) in the diagnosis of recurrence or the assessment of therapeutic response in cervical and ovarian cancer patients through making a comparison between FDG-PET, abdominal computed tomography (CT) and serum tumor marker. We included 103 cases (67 patients) performed FDG-PET and abdominal CT. There were 42 cervical cancers and 61 ovarian cancers. We retrospectively reviewed the interpretations of PET and CT images as well as the level of tumor marker. We calculated their sensitivity, specificity, positive predictive value and negative predictive value for these three modalities. And then we analyzed the differences between these three modalities. Tumor recurrences were diagnosed in 37 cases (11 cervical cancers and 26 ovarian cancers). For PET, CT and tumor marker, in cervical cancer group, sensitivity was 100% (11/11), 54.5% (6/11) and 81.1% (9/11), respectively. And specificity was 93.6% (29/31), 93.6% (29/31) and 100% (31/31). In ovarian cancer group, sensitivity was 96.2% (25/26), 84.6% (22/26) and 80.8% (21/26), and specificity was 94.3% (33/35), 94.3% (33/35), 94.3% (33/35). PET was highly sensitive to detect the intraperitoneal and extraperitoneal metastasis with the help of the CT images to localize the lesions. However, CT had limitations in differentiation of the recurrent tumor from benign fibrotic tissue, identification of viable tumors at the interface of tissues, and detecting extraperitoneal lesions. FDG-PET can be an essential modality to detect the recurrent or residual tumors in gynecologic cancer patients because of its great field of the application and high sensitivity

    The PARP inhibitor olaparib was recently granted Food and Drug Administration (FDA) accelerated approval in patients with advanced BRCA1/2 mutation ovarian cancer. However, antitumor responses are observed in only approximately 40% of patients and the impact of baseline clinical factors on response to treatment remains unclear. Although platinum sensitivity has been suggested as a marker of response to PARP inhibitors, patients with platinum-resistant disease still respond to olaparib. 108 patients with advanced BRCA1/2 mutation ovarian cancers were included. The interval between the end of the most recent platinum chemotherapy and PARPi (PTPI) was used to predict response to olaparib independent of conventional definition of platinum sensitivity. RECIST complete response (CR) and partial response (PR) rates were 35% in patients with platinum-sensitive versus 13% in platinum-resistant (p<0.005). Independent of platinum sensitivity status, the RECIST CR/PR rates were 42% in patients with PTPI greater than 52 weeks and 18% in patients with PTPI less than 52 weeks (p=0.016). No association was found between baseline clinical factors such as FIGO staging, debulking surgery, BRCA1 versus BRCA2 mutations, prior history of breast cancer and prior chemotherapy for breast cancer, and the response to olaparib. We conducted an international multicenter retrospective study to investigate the association between baseline clinical characteristics of patients with advanced BRCA1/2 mutation ovarian cancers from eight different cancer centers and their antitumor response to olaparib. PTPI may be used to refine the prediction of response to PARP inhibition based on the conventional categorization of platinum sensitivity.

    Germline deleterious mutations in the BRCA1/BRCA2 genes are associated with an increased risk for the development of breast and ovarian cancer. Given the large size of these genes the detection of such mutations represents a considerable technical challenge. Therefore, the development of cost-effective and rapid methods to identify these mutations became a necessity. High resolution melting analysis (HRM) is a rapid and efficient technique extensively employed as high-throughput mutation scanning method. The purpose of our study was to assess the specificity and sensitivity of HRM for BRCA1 and BRCA2 genes scanning. As a first step we estimate the ability of HRM for detection mutations in a set of 21 heterozygous samples harboring 8 different known BRCA1/BRCA2 variations, all samples had been preliminarily investigated by direct sequencing, and then we performed a blinded analysis by HRM in a set of 68 further sporadic samples of unknown genotype. All tested heterozygous BRCA1/BRCA2 variants were easily identified. However the HRM assay revealed further alteration that we initially had not searched (one unclassified variant). Furthermore, sequencing confirmed all the HRM detected mutations in the set of unknown samples, including homozygous changes, indicating that in this cohort, with the optimized assays, the mutations detections sensitivity and specificity were 100 %. HRM is a simple, rapid and efficient scanning method for known and unknown BRCA1/BRCA2 germline mutations. Consequently the method will allow for the economical screening of recurrent mutations in Tunisian population.

    To assess the usefulness of cancer antigen 125 (CA125) serum levels and kinetic values, velocity (CA125vel) and doubling time (CA125dt), as well as fluorodeoxyglucose ([ 18 F]FDG) positron emission tomography/computed tomography (PET/CT), in the detection of ovarian cancer recurrence. To assess the optimal cut-off for CA125, CA125vel and CA125dt to detect relapse with [ 18 F]FDG-PET/CT. A retrospective analysis was performed of 59 [ 18 F]FDG-PET/CT (48 patients) for suspected recurrence of ovarian cancer. Receiver operating characteristic (ROC) curves were plotted and area-under-the curve (AUC) statistics were computed for CA125, CA125vel and CA125dt. The results obtained in the group with normal and high (>35U/ml) CA125 levels were compared. Forty-four cases of recurrence were diagnosed (7 had CA125 ≤35U/ml), whereas 15 showed no disease. All of them were correctly catalogued by PET/CT. In ROC analysis, the discriminatory power of CA125 was relatively high (AUC 0.835) and the optimal cut-off point to reflect active disease was 23.9U/ml. The ROC analyses for the CA125vel and CA125dt showed an AUC of 0.849 and 0.728, respectively, with an optimal cut-off point of 1.96U/ml/month and 0.76 months, respectively. In patients with normal CA125 and recurrence of ovarian cancer, the CA125vel was significantly higher than in patients without recurrence (p=0.029). [ 18 F]FDG-PET/CT is more accurate than CA125 parameters in the detection of ovarian cancer recurrence. CA125 serum levels are essential; nevertheless, CA125 kinetic values must be considered to detect relapse. Particularly in patients with CA125 within normal values, in which a higher CA125vel is indicative of recurrence. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Our aim was to evaluate the associations between quantitative {sup 18}F-fluorodeoxyglucose positron-emission tomography (FDG-PET) uptake metrics, optimal debulking (OD) and progression-free survival (PFS) in patients with recurrent ovarian cancer undergoing secondary cytoreductive surgery. Fifty-five patients with recurrent ovarian cancer underwent FDG-PET/CT within 90 days prior to surgery. Standardized uptake values (SUV{sub max}), metabolically active tumour volumes (MTV), and total lesion glycolysis (TLG) were measured on PET. Exact logistic regression, Kaplan-Meier curves and the log-rank test were used to assess associations between imaging metrics, OD and PFS. MTV (p = 0.0025) and TLG (p = 0.0043) were associated with OD; however, there was no significant association between SUV{sub max} and debulking status (p = 0.83). Patients with an MTV above 7.52 mL and/or a TLG above 35.94 g had significantly shorter PFS (p = 0.0191 for MTV and p = 0.0069 for TLG). SUV{sub max} was not significantly related to PFS (p = 0.10). PFS estimates at 3.5 years after surgery were 0.42 for patients with an MTV ≤ 7.52 mL and 0.19 for patients with an MTV > 7.52 mL; 0.46 for patients with a TLG ≤ 35.94 g and 0.15 for patients with a TLG > 35.94 g. FDG-PET metrics that reflect metabolic tumour burden are associated with optimal secondary cytoreductive surgery and progression-free survival in patients with recurrent ovarian cancer. (orig.)

    Full Text Available Abstract Background Carboplatin/paclitaxel is the chemotherapy of choice for advanced ovarian cancer, both in first line and in platinum-sensitive recurrence. Although a significant proportion of patients have some neurotoxicity during treatment, the long-term outcome of chemotherapy-induced neuropathy has been scantly studied. We retrospectively assessed the prevalence of residual neuropathy in a cohort of patients in clinical remission after first-line carboplatin/paclitaxel for advanced ovarian cancer.

    Carboplatin/paclitaxel is the chemotherapy of choice for advanced ovarian cancer, both in first line and in platinum-sensitive recurrence. Although a significant proportion of patients have some neurotoxicity during treatment, the long-term outcome of chemotherapy-induced neuropathy has been scantly studied. We retrospectively assessed the prevalence of residual neuropathy in a cohort of patients in clinical remission after first-line carboplatin/paclitaxel for advanced ovarian cancer. 120 patients have been included in this study (101 participating in a multicentre phase III trial evaluating the efficacy of consolidation treatment with topotecan, and 19 treated at the National Cancer Institute of Naples after the end of the trial). All patients received carboplatin (AUC 5) plus paclitaxel (175 mg/m 2 ) every 3 weeks for 6 cycles, completing treatment between 1998 and 2003. Data were collected between May and September 2004.

    To date, a limited number of BRCA1/2 germline mutations have been reported in hereditary breast and/or ovarian cancer in the Moroccan population. Less than 20 different mutations of these two genes have been identified in Moroccan patients, and recently we reported a further BRCA2 mutation (c.1310_1313delAAGA; p.Lys437IlefsX22) in three unrelated patients, all from the North-East of the country. We aimed in this study to evaluate the frequency and geographic distribution of this BRCA2 frameshift mutation, in order to access its use as the first-line BRCA genetic testing strategy for Moroccan patients. We enrolled in this study 122 patients from different regions of Morocco, with suggestive inherited predisposition to breast and ovarian cancers. All subjects gave written informed consent to BRCA1/2 genetic testing. According to available resources of our lab and enrolled families, 51 patients were analyzed by the conventional individual exon-by-exon Sanger sequencing, 23 patients were able to benefit from a BRCA next generation sequencing and a target screening for exon 10 of BRCA2 gene was performed in 48 patients. Overall, and among the 122 patients analyzed for at least the exon 10 of the BRCA2 gene, the c.1310_1313delAAGA frameshift mutation was found in 14 patients. Genealogic investigation revealed that all carriers of this mutation shared the same geographic origin and were descendants of the North-East of Morocco. In this study, we highlighted that c.1310_1313delAAGA mutation of BRCA2 gene is recurrent with high frequency in patients from the North-East region of Morocco. Therefore, we propose to use, in public health strategies, the detection of this mutation as the first-line screening tests in patients with breast and ovarian cancer originated from this region.

    Chemotherapy for platinum-resistant/refractory ovarian cancer is motivated by the hope of benefit. Trait hope and expectation of symptom benefit from chemotherapy appear to be distinct and independent of quality of life and depression. Hope did not appear to affect perceived efficacy of chemotherapy in alleviating symptoms, but women whose expectation of symptom benefit from chemotherapy was not fulfilled were more likely to have scores indicative of depression.

    Chemotherapy for platinum-resistant/refractory ovarian cancer is motivated by the hope of benefit. We sought to determine the relationships between: (a) trait hope, expectation of symptom benefit from chemotherapy, and anxiety and depression; (b) hope and perceived efficacy of chemotherapy; and (c) unfulfilled hope (where expectations for benefit are not fulfilled) and depression. Methods. Adult patients enrolled within stage 1 of the Gynecologic Cancer Intergroup Symptom Benefit Study were included. Patient. Reported outcomes were collected from 126 women with predominantly platinum-resistant ovarian cancer at baseline, prior to the first four treatment cycles (12-16 weeks), and four weeks after completing chemotherapy or at disease progression, whichever came first. Associations were assessed with Spearman rank correlation coefficient (r) and odds ratio. Results. Trait hope and expectation of symptom benefit from chemotherapy were weakly correlated with each other (r = 0.25). Trait hope, but not expectation of symptom benefit, was negatively correlated with anxiety (r = -0.43) and depression (r = -0.50). The smaller the discrepancy between perceived and expected symptom benefit, the less likely the patient was to have scores indicative of depression (odds ratio: 0.68; 95% confidence interval: 0.49-0.96; p = .026). Conclusion. Trait hope and expectation of symptom benefit from chemotherapy appear to be distinct and independent of the aspects of quality of life and scores for depression. Hope did not appear to affect perceived efficacy of chemotherapy in alleviating symptoms, but women whose expectation of symptom benefit from chemotherapy was not fulfilled were more likely to have scores indicative of depression. It may be preferable to encourage hope toward achievable goals rather than toward benefits from chemotherapy.

    Purpose : We tried to evaluate the clinical characteristics, the treatment methods, the results of treatments, and the patterns of failure in ovarian dysgerminoma retrospectively. According to the results we would like to suggest the proper management guideline of stage la ovarian dysgerminoma patients who want to maintain fertility. Methods and Materials : Between 1975 and 1990, 34 patients with ovarian dysgerminoma were treated at the Yonsei University Hospital. The case records of these patients have been reviewed for presenting symptoms, treatment methods, local control, and survival following treatment. Excluded from analysis were five patients with mixed ovarian germ cell tumors and gonadoblastomas (46,XY). Treatment results of the twenty nine patients were analysed by each treatment modality. Twenty one patients were treated with surgery and postoperative adjuvant radiotherapy(group 1). The other eight patients were treated with operation alone (group 2). The median age of twenty-nine patients was 23 years with a range of 8 to 39 years. Presenting symptoms were abdominal mass(20), pelvic discomfort or pain(5) et al. Radiotherapy was performed by 10MV LINAC or Co-60 teletherapy unit. The total radiation dose of the whole abdomen was 20-25 Gy/3 weeks, 1-1.5 Gy/fraction with a boost to the whole pelvis 10-15 Gy / 1-2 weeks1.8-2.0 Gy/fraction. Advanced stage disease (stage II or stage III) patients received prophylactic mediastinal and supraclavicular irradiation to a dose of 16-26 Gy. Median duration of follow-up of living patients was 80 months (range : 13-201 months). Results : All of the twenty one patients of group 1 were alive without disease (100%). Among the eight patients who were not treated with radiotherapy (group 2), six patients developed local recurrence. Four patients referred with recurrent disease were treated with salvage radiotherapy. Three of four patients were salvaged and one patient who had recurrent intra-abdominal disease died of

    Dimitra T Stefanou

    Full Text Available Ovarian carcinoma (OC is the most lethal gynecological malignancy. Despite the advances in the treatment of OC with combinatorial regimens, including surgery and platinum-based chemotherapy, patients generally exhibit poor prognosis due to high chemotherapy resistance. Herein, we tested the hypothesis that DNA damage response (DDR pathways are involved in resistance of OC patients to platinum chemotherapy. Selected DDR signals were evaluated in two human ovarian carcinoma cell lines, one sensitive (A2780 and one resistant (A2780/C30 to platinum treatment as well as in peripheral blood mononuclear cells (PBMCs from OC patients, sensitive (n = 7 or resistant (n = 4 to subsequent chemotherapy. PBMCs from healthy volunteers (n = 9 were studied in parallel. DNA damage was evaluated by immunofluorescence γH2AX staining and comet assay. Higher levels of intrinsic DNA damage were found in A2780 than in A2780/C30 cells. Moreover, the intrinsic DNA damage levels were significantly higher in OC patients relative to healthy volunteers, as well as in platinum-sensitive patients relative to platinum-resistant ones (all P<0.05. Following carboplatin treatment, A2780 cells showed lower DNA repair efficiency than A2780/C30 cells. Also, following carboplatin treatment of PBMCs ex vivo, the DNA repair efficiency was significantly higher in healthy volunteers than in platinum-resistant patients and lowest in platinum-sensitive ones (t1/2 for loss of γH2AX foci: 2.7±0.5h, 8.8±1.9h and 15.4±3.2h, respectively; using comet assay, t1/2 of platinum-induced damage repair: 4.8±1.4h, 12.9±1.9h and 21.4±2.6h, respectively; all P<0.03. Additionally, the carboplatin-induced apoptosis rate was higher in A2780 than in A2780/C30 cells. In PBMCs, apoptosis rates were inversely correlated with DNA repair efficiencies of these cells, being significantly higher in platinum-sensitive than in platinum-resistant patients and lowest in healthy volunteers (all P<0.05.

    2004-01-01

    Splenic metastases occur in rare cases with a few case reports of patients in the literature. Generally, splenic metastases mean late dissemination of a disease. Solitary splenic metastases from solid tumors are extremely unusual. We report a case of a patient with ovarian mucinous cystadenocarcinoma who underwent splenectomy for isolated parenchymal metastasis. Ovarian epithelial tumors comprised most of isolated splenic metastases from gynecologic tumor. When isolated splenic recurrence is suspected on image studies and serum tumor markers, intraabdominal gross findings should be examined to exclude peritoneal carcinomatosis. If only spleen was under suspicion of recurrence of ovarian cancer, splenectomy may play a therapeutic role

    The aim of this study is to evaluate prospectively the presence of endometriosis in the peritoneum of the ovarian fossa of patients affected by endometriomas and its correlation with the adhesion between this peritoneum and endometrioma. Patients presenting ovarian endometriomas and candidate to laparoscopy were considered for inclusion in the study. Patients underwent laparoscopic excision of endometriomas. The presence of adherence of the ovarian fossa to endometrioma was investigated. In all patients, the removal of a peritoneum fragment from the ovarian fossa of the affected ovary was carried out. 68 patients were enrolled in the study. 48 patients presented adhesions to the ovarian fossa. Histopathologic examination of the peritoneum of the ovarian fossa revealed the presence of endometriosis in 87 % of patients presenting adhesions of the endometriomas with ovarian fossa; surprisingly it was present only in 15 % of patients not presenting this condition (p endometriosis on the peritoneal surface of the fossa. This condition significantly correlates with pain symptoms and may predict endometrioma recurrence. The removal of this peritoneum in case of adherent endometrioma may potentially reduce the incidence of recurrence.

    Cancer markers may be developed to detect diseases characterized by increased expression of apoptosis-suppressing genes, such as aggressive cancers. Genes in the human chromosomal regions, 8q24, 11q13, 20q11-q13, were found to be amplified indicating in vivo drug resistance in diseases such as ovarian cancer. Diagnosis and assessment of amplification levels certain genes shown to be amplified, including PVT1, can be useful in prediction of poor outcome of patient's response and drug resistance in ovarian cancer patients with low survival rates. Certain genes were found to be high priority therapeutic targets by the identification of recurrent aberrations involving genome sequence, copy number and/or gene expression are associated with reduced survival duration in certain diseases and cancers, specifically ovarian cancer. Therapeutics to inhibit amplification and inhibitors of one of these genes, PVT1, target drug resistance in ovarian cancer patients with low survival rates is described.

  14. Nuclear COMMD1 Is Associated with Cisplatin Sensitivity in Ovarian Cancer.

    Directory of Open Access Journals (Sweden)

    Alina Fedoseienko

    Full Text Available Copper metabolism MURR1 domain 1 (COMMD1 protein is a multifunctional protein, and its expression has been correlated with patients' survival in different types of cancer. In vitro studies revealed that COMMD1 plays a role in sensitizing cancer cell lines to cisplatin, however, the mechanism and its role in platinum sensitivity in cancer has yet to be established. We evaluated the role of COMMD1 in cisplatin sensitivity in A2780 ovarian cancer cells and the relation between COMMD1 expression and response to platinum-based therapy in advanced stage high-grade serous ovarian cancer (HGSOC patients. We found that elevation of nuclear COMMD1 expression sensitized A2780 ovarian cancer cells to cisplatin-mediated cytotoxicity. This was accompanied by a more effective G2/M checkpoint, and decreased protein expression of the DNA repair gene BRCA1, and the apoptosis inhibitor BCL2. Furthermore, COMMD1 expression was immunohistochemically analyzed in two tissue micro-arrays (TMAs, representing a historical cohort and a randomized clinical trial-based cohort of advanced stage HGSOC tumor specimens. Expression of COMMD1 was observed in all ovarian cancer samples, however, specifically nuclear expression of COMMD1 was only observed in a subset of ovarian cancers. In our historical cohort, nuclear COMMD1 expression was associated with an improved response to chemotherapy (OR = 0.167; P = 0.038, although this association could not be confirmed in the second cohort, likely due to sample size. Taken together, these results suggest that nuclear expression of COMMD1 sensitize ovarian cancer to cisplatin, possibly by modulating the G2/M checkpoint and through controlling expression of genes involved in DNA repair and apoptosis.

    Undescended ovary is a rare disorder that can be associated with muellerian malformations. There is an unclear association with infertility and malignant disease. When an ovary is not in its normal location, it is sought in other locations above the pelvic brim. This is important in cases of undetermined cyclical abdominal pain, follicle aspiration and surgical castration. MRI has proven to be the best imaging method for finding an ovary in an anomalous position and for disregarding associated malformations. We report two patients with unilateral ovarian maldescent, one of them with Rokitansky-Kuester-Hauser syndrome. A review of the literature is included. (orig.)

    Full Text Available Varicocele recurrence is one of the most common complications associated with varicocele repair. A systematic review was performed to evaluate varicocele recurrence rates, anatomic causes of recurrence, and methods of management of recurrent varicoceles. The PubMed database was evaluated using keywords "recurrent" and "varicocele" as well as MESH criteria "recurrent" and "varicocele." Articles were not included that were not in English, represented single case reports, focused solely on subclinical varicocele, or focused solely on a pediatric population (age <18. Rates of recurrence vary with the technique of varicocele repair from 0% to 35%. Anatomy of recurrence can be defined by venography. Management of varicocele recurrence can be surgical or via embolization.

    Exosomes have been implicated in the cell-cell transfer of oncogenic proteins and genetic material. We speculated this may be one mechanism by which an intrinsically platinum-resistant population of epithelial ovarian cancer (EOC) cells imparts its influence on surrounding tumor cells. To explore this possibility we utilized a platinum-sensitive cell line, A2780 and exosomes derived from its resistant subclones, and an unselected, platinum-resistant EOC line, OVCAR10. A2780 cells demonstrate a ~2-fold increase in viability upon treatment with carboplatin when pre-exposed to exosomes from platinum-resistant cells as compared to controls. This coincided with increased epithelial to mesenchymal transition (EMT). DNA sequencing of EOC cell lines revealed previously unreported somatic mutations in the Mothers Against Decapentaplegic Homolog 4 (SMAD4) within platinum-resistant cells. A2780 cells engineered to exogenously express these SMAD4 mutations demonstrate up-regulation of EMT markers following carboplatin treatment, are more resistant to carboplatin, and release exosomes which impart a ~1.7-fold increase in resistance in naive A2780 recipient cells as compared to controls. These studies provide the first evidence that acquired SMAD4 mutations enhance the chemo-resistance profile of EOC and present a novel mechanism in which exchange of tumor-derived exosomes perpetuates an EMT phenotype, leading to the development of subpopulations of platinum-refractory cells.

  19. Ovarian adenosarcoma simulating a simple cyst in a young patient

    Directory of Open Access Journals (Sweden)

    Leonardo Gomes da Fonseca

    2014-06-01

    Full Text Available Müllerian adenosarcoma is a rare, mixed tumor that can occur throughout the female genital tract, but is most commonly found in the uterus. Ovarian adenosarcoma is rarer and has a poorer prognosis than uterine adenosarcoma. Data on the clinicopathological features of ovarian adenosarcoma are limited, and, due to its rarity, the management is controversial. The authors report a case of a 25-year-old patient who presented with recurrent abdominal pain. Sonography and laparotomy showed an ovarian cyst, and pathologic examination confirmed the diagnosis of cystic low-grade adenosarcoma. The patient remains free of recurrence 6 months after diagnosis. The authors call attention to the differential diagnosis of ovarian masses, especially in young patients, and to the lack of evidence on the management of this neoplasm in the literature.

    Rosenberg, Jon; Galen, Benjamin T

    2017-07-01

    Recurrent meningitis is a rare clinical scenario that can be self-limiting or life threatening depending on the underlying etiology. This review describes the causes, risk factors, treatment, and prognosis for recurrent meningitis. As a general overview of a broad topic, the aim of this review is to provide clinicians with a comprehensive differential diagnosis to aide in the evaluation and management of a patient with recurrent meningitis. New developments related to understanding the pathophysiology of recurrent meningitis are as scarce as studies evaluating the treatment and prevention of this rare disorder. A trial evaluating oral valacyclovir suppression after HSV-2 meningitis did not demonstrate a benefit in preventing recurrences. The data on prophylactic antibiotics after basilar skull fractures do not support their use. Intrathecal trastuzumab has shown promise in treating leptomeningeal carcinomatosis from HER-2 positive breast cancer. Monoclonal antibodies used to treat cancer and autoimmune diseases are new potential causes of drug-induced aseptic meningitis. Despite their potential for causing recurrent meningitis, the clinical entities reviewed herein are not frequently discussed together given that they are a heterogeneous collection of unrelated, rare diseases. Epidemiologic data on recurrent meningitis are lacking. The syndrome of recurrent benign lymphocytic meningitis described by Mollaret in 1944 was later found to be closely related to HSV-2 reactivation, but HSV-2 is by no means the only etiology of recurrent aseptic meningitis. While the mainstay of treatment for recurrent meningitis is supportive care, it is paramount to ensure that reversible and treatable causes have been addressed for further prevention.

    Background: Although CA125 kinetic profiles may be related with relapse risk in ovarian cancer patients treated with chemotherapy, no reliable kinetic parameters have been reported. Mathematical modeling may help describe CA125 decline dynamically and determine parameters predictive of relapse....... Methods: Data from CALYPSO phase III trial data comparing 2 carboplatin-based regimens in ROC patients were analyzed. Based on population kinetic approach (Monolix software), a semi-mechanistic model was used to fit serum log (CA125) concentration-time profiles with following parameters: tumor growth rate...... the first 50 treatment days were tested regarding progression free survival (PFS) against other reported prognostic factors using Cox-models: treatment arm; platinum-free interval (PFI), metastatic site number, largest tumor size, elevated WBC and measurable disease. Results: The CA125 kinetics from 898...

  6. The Roles of Laparoscopy in Treating Ovarian Cancer

    2009-03-01

    Full Text Available Great advances in technology offer meticulous options of minimally invasive surgery to empower the gynecologists to manage patients of early ovarian cancer. Laparoscopy affords improved visualization of the pelvic peritoneum, diaphragm and the deep pelvic structures, and offers many advantages in the avoidance of long abdominal incision, including shorter hospital stay and a more rapid recovery time. Most studies showed that laparoscopy did not compromise the survival and recurrence prognosis in comparison with open abdominal approach of staging surgery. Contrarily, laparoscopy precludes the advantage of open surgery, such as manual examination of the full extent of the bowel and palpation of lymph nodes. Besides, laparoscopy technically hampers the removal of large ovarian mass, and laparoscopic cancer surgery has a potential risk of trocar site metastasis. As the trend shows that laparoscopy has been playing an important role in treating early ovarian cancer, we could expect laparoscopy to become an attractive surgical option in the future for ovarian cancers.

    Full Text Available Abstract Premature ovarian failure (POF is a primary ovarian defect characterized by absent menarche (primary amenorrhea or premature depletion of ovarian follicles before the age of 40 years (secondary amenorrhea. It is a heterogeneous disorder affecting approximately 1% of women e.g. Turner syndrome represent the major cause of primary amenorrhea associated with ovarian dysgenesis. Despite the description of several candidate genes, the cause of POF remains undetermined in the vast majority of the cases. Management includes substitution of the hormone defect by estrogen/progestin preparations. The only solution presently available for the fertility defect in women with absent follicular reserve is ovum donation.

    Ovarian fibromas are the most common benign solid ovarian tumors, which are often difficult to diagnose preoperatively. Ovarian fibromas, especially in bilateral cases, may be cases of Gorlin-Goltz syndrome (GGS), a rare autosomal dominant disorder with predisposition to basal cell carcinomas (BCCs) and other various benign and malignant tumors. This case report describes a 25 year-old female with GGS, bilateral ovarian fibroma, endometriosis and septated uterus, which was referred to the Gynecology Clinic of Rasoul-e-Akram Hospital in October 2016. This patient had facial asymmetry due to recurrent odontogenic keratocysts. In young cases of ovarian fibromas as reported here, conservative surgical management can preserve ovarian function and fertility. These patients must be followed up by a multidisciplinary team and submitted to periodic tests. Copyright© by Royan Institute. All rights reserved.

    We are currently faced with a progressive delay in the age at which women conceive for the first time. This raises the possibility of the appearance of gynecologic disorders that may affect fertility, including neoplasms of the ovary. Fertility-sparing surgery is defined as the preservation of ovarian tissue in one or both adnexa and/or the uterus. Borderline ovarian tumor should be treated with conservative surgery. Salpingo-oophorectomy, or even ovarian cystectomy, are the procedures of choice, with recurrence rates of 2-3% and up to 20% if a simple cystectomy is performed. Cystectomy is indicated in patients with bilateral borderline tumors or in patients with a residual ovary. Borderline tumors with invasive peritoneal implants behave as an invasive cancer in 10-30% of cases with a survival rate of 10-66% compared with 100% in borderline tumors without invasive implants. Prophylactic oophorectomy is recommended when desire of conception has been accomplished. Conservative surgery in invasive epithelial ovarian cancer is limited to Stage IA, grade 1 tumor, and in some highly selected grade 2 tumors of serous, mucinous or endometrioid type, well-encapsulated and free of adhesions. The standard oncological surgical procedure with preservation of the uterus and normal appearing ovary is recommended. This includes salpingo-oophorectomy, excision of any suspicious peritoneal lesion, multiple peritoneal biopsies, appendectomy (particularly in mucinous tumors), and pelvic and paraaortic lymphadenectomy.

    Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV. Copyright © 2014 Elsevier Ltd. All rights reserved.

  17. Autoimmune premature ovarian failure

    Directory of Open Access Journals (Sweden)

    Beata Komorowska

    2017-02-01

    Full Text Available Premature ovarian failure (POF, also termed as primary ovarian insufficiency (POI, is a highly heterogenous condition affecting 0.5-3.0% of women in childbearing age. These young women comprise quite a formidable group with unique physical and psychological needs that require special attention. Premature ovarian senescence (POS in all of its forms evolves insidiously as a basically asymptomatic process, leading to complete loss of ovarian function, and POI/POF diagnoses are currently made at relatively late stages. Well-known and well-documented risk factors exist, and the presence or suspicion of autoimmune disorder should be regarded as an important one. Premature ovarian failure is to some degree predictable in its occurrence and should be considered while encountering young women with loss of menstrual regularity, especially when there is a concomitant dysfunction in the immune system.

    2006-04-01

    Ovarian cancer is the leading cause of death from gynaecological malignancy. The incidence is high in the Western world. The incidence of ovarian cancer is reduced by pregnancy, lactation, the oral contraceptive pill and tubal ligation. Lifestyle factors are important in the aetiology of ovarian cancer and current evidence suggests the risk can be reduced by eating a diet rich in fruit and vegetables, taking regular exercise, avoiding smoking, avoiding being overweight and avoiding long-term use of hormonal replacement therapy (HRT). Familial ovarian cancer is responsible for about 10% of ovarian cancer cases. Strategies available to high-risk women include screening (covered elsewhere) and prophylactic salpingo-oophorectomy. The precise role of chemoprevention for high-risk women in the form of the oral contraceptive pill is unclear.

  6. Clinical Application of 18F-FDG PET in Ovarian Cancer

    International Nuclear Information System (INIS)

    Oh, So Won; Kim, Seok Ki

    2008-01-01

    Ovarian cancer is often fatal since it is difficult to diagnose early and recurrence is quite frequent despite successful implementation of cytoreductive surgery and chemotherapy, thus exact diagnosis and early detection of recurrence are crucial to patient management. For pre-treatment staging, FDG PET could be helpful in a limited patient group possessing high risks of ovarian cancer. Besides, FDG PET could be recommended to patients with a high suspicion of recurrence i.e. rise of CA-125, especially in cases of conventional diagnostic imaging modalities presenting no evidence of disease because FDG PET provides critical information for treatment planning such as recurrence site or pattern. In order to expand the use of FDG PET to general population at staging or routine surveillance of ovarian cancer, more investigation is needed. The usefulness of FDG PET in evaluating treatment response and prognosis of ovarian cancer has not yet been determined, but it has been reported that FDG PET could evaluate treatment response early and show a close relationship with overall survival. PET/CT has been actively adopted in management of ovarian cancer. Not only in detecting tumor recurrence and evaluating treatment response but also in pre-treatment staging, FDG PET/CT is expected to play a role due to available anatomical information

    Full Text Available Background. Primary ovarian malignant melanoma is extremely rare. It usually appears in the wall of a dermoid cyst or is associated with another teratomatous component. Metastatic primary malignant melanoma to ovary from a primary melanoma elsewhere is well known and has been often reported especially in autopsy studies. Case report. We presented a case of primary ovarian malignant melanoma in a 45- year old woman, with no evidence of extraovarian primary melanoma nor teratomatous component. The tumor was unilateral, macroscopically on section presented as solid mass, dark brown to black color. Microscopically, tumor cells showed positive immunohistochemical reaction for HMB-45, melan-A and S-100 protein, and negative immunoreactivity for estrogen and progesteron receptors. Conclusion. Differentiate metastatic melanoma from rare primary ovarian malignant melanoma, in some of cases may be a histopathological diagnostic problem. Histopathological diagnosis of primary ovarian malignant melanoma should be confirmed by immunohistochemical analyses and detailed clinical search for an occult primary tumor.

    2014-01-01

    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.

    Fibrolamellar carcinoma (FLC) has been considered a distinct clinical entity vs. hepatocellular carcinoma, with respect to its epidemiology, etiology, and prognosis. We describe the unusual case of a 23-year-old female patient with FLC and ovarian (Krukenberg) and peritoneal metastases, clinically mimicking an ovarian carcinoma. Multiple recurrences occurred despite initial R0 resection and chemotherapy, requiring surgical treatment. The patient survived five years and died from generalized disease. The particularities of our case are discussed by comparison with the other two similar cases and other date from the literature. To our knowledge, the ovarian involvement encountered in our case is the third case published in literature, being explained by the superficial location of the liver tumor.

    Hyaluronan (HA) an important component of the extracellular matrix, has been linked to tumor progression and drug resistance in several malignancies. However, limited data is available for ovarian cancer. This study investigated the role of hyaluronan (HA) and a potential link between the HA-CD44 pathway and membrane ATP binding cassette (ABC) transporter proteins in ovarian cancer chemoresistance. We investigated the ability of HA to block the cytotoxic effects of the chemotherapy drug carboplatin, and to regulate the expression of ABC transporters in ovarian cancer cells. We also examined HA serum levels in ovarian cancer patients prior to and following chemotherapy and assessed its prognostic relevance. HA increased the survival of carboplatin treated ovarian cancer cells expressing the HA receptor, CD44 (OVCAR-5 and OV-90). Carboplatin significantly increased expression of HAS2, HAS3 and ABCC2 and HA secretion in ovarian cancer cell conditioned media. Serum HA levels were significantly increased in patients following platinum based chemotherapy and at both 1st and 2nd recurrence when compared with HA levels prior to treatment. High serum HA levels (>50 μg/ml) prior to chemotherapy treatment were associated with significantly reduced progression-free (P = 0.014) and overall survival (P = 0.036). HA production in ovarian cancer cells was increased in cancer tissues collected following chemotherapy treatment and at recurrence. Furthermore HA treatment significantly increased the expression of ABC drug transporters (ABCB3, ABCC1, ABCC2, and ABCC3), but only in ovarian cancer cells expressing CD44. The effects of HA and carboplatin on ABC transporter expression in ovarian cancer cells could be abrogated by HA oligomer treatment. Importantly, HA oligomers increased the sensitivity of chemoresistant SKOV3 cells to carboplatin. Our findings indicate that carboplatin chemotherapy induces HA production which can contribute to chemoresistance by regulating ABC

    Approximately 50% of high-grade serous ovarian cancers present a deficiency in the pathways involved in homologous recombination (HR). PARP inhibitors prevent single-strand DNA damage repair and determine a progression of the defect towards double-strand breaks, which results in a process known as 'synthetic lethality'. Areas covered: In this review, the authors discuss the efficacy and toxicity of rucaparib either as a single agent or as a maintenance treatment for ovarian cancer. This includes the NGS Foundation Medicine evaluation of the role of this drug in the treatment algorithm of ovarian cancer. Moreover, perspectives on the future development of this drug are presented. Expert opinion: The FDA has approved this drug for the treatment of recurrent BRCA-mutated ovarian cancers, which were previously treated with at least two chemotherapies and has accepted the supplemental new drug application for maintenance use in patients who respond to platinum-based chemotherapy via the Prescription Drug User Fee Act (PDUFA) on 6 April 2018. European Medicines Agency (EMA) approval in the same setting is awaited. The possibility of using PARP inhibitors as a maintenance therapy, as a front-line therapy to combat recurrence, and in combination with anti-angiogenic agents and immune-therapies appears to be of particular interest.

    The fixed primordial follicles pool theory, which monopolized reproductive medicine for more than one hundred years, has been broken by the discovery, successful isolation and establishment of ovarian stem cells. It has brought more hope than ever of increasing the size of primordial follicle pool, improving ovarian function and delaying ovarian consenescence. Traditional view holds that stem cell aging contributes to the senility of body and organs. However, in the process of ovarian aging, the main factor leading to the decline of the reproductive function is the aging and degradation of ovarian stem cell nests, rather than the senescence of ovarian germ cells themselves. Recent studies have found that the immune system and circulatory system are involved in the formation of ovarian germline stem cell niches, as well as regulating the proliferation and differentiation of ovarian germline stem cells through cellular and hormonal signals. Therefore, we can improve ovarian function and delay ovarian aging by improving the immune system and circulatory system, which will provide an updated program for the treatment of premature ovarian failure (POF) and infertility. © 2017 The Author(s).

    Full Text Available Although genito-urinary tuberculosis is common, reports of isolated ovarian tubercular abscess are rare. Ovarian tubercular abscess may mimics that of an ovarian tumor, leading to diagnostic difficulties. We reported a case report of 35 years woman presented with chronic pain abdomen, weight loss, low-grade fever and a right ovarian mass on ultrasound, with a significantly elevated CA-125 level. On clinical and radiological evidence, diagnosis of ovarian carcinoma was made, and laparotomy was performed with resection of the ovary. Postoperative specimen sent for histological examination that revealed classic epithelioid granuloma and acid-fast bacilli were present in Ziehl-Neelsen stain. Patient was put on antitubercular regimen from our Dots center. She is improving clinical after taking antitubercular drug and is on regular follow up at our chest outpatient department. Ovarian tubercular abscess is common in young women living in endemic zones, but case report of isolated tubercular abscess is rarely reported. CA-125 can be raised in both ovarian tubercular abscess and ovarian carcinoma, and only imaging is not always conclusive. Laparotomy followed by tissue diagnosis can be helpful in this situation. As the prognosis and treatment outcome of ovarian tubercular abscess and ovarian carcinoma is different, proper diagnosis by laparotomy should be done. Early diagnosis of ovarian tubercular abscess is vital as untreated disease can lead to infertility.

    To evaluate the prognostic value of metabolic activity of metastatic lesions measured by 18 F-flurodeoxyglucose ( 18 F-FDG) uptake on preoperative positron emission tomography/computed tomography (PET/CT) in patients with advanced serous epithelial ovarian cancer (EOC). Clinico-pathological variables and PET/CT parameters such as the maximum standardised uptake value of the ovarian cancer (SUV ovary ), metastatic lesions (SUV meta ), and the metastatic lesion-to-ovarian cancer standardised uptake value ratio (SUV meta /SUV ovary ) were assessed in International Federation of Gynaecology and Obstetrics (FIGO) stage III, IV patients. Clinico-pathological data were retrospectively reviewed for 94 eligible patients. The median progression-free survival (PFS) was 18.5 months (range, 6-90 months), and 57 (60.6%) patients experienced recurrence. Older age [P = 0.017, hazard ratio (HR) 1.036, 95% CI 1.006-1.066], residual disease after surgery (P = 0.024, HR 1.907, 95% CI 1.087-3.346), and high SUV meta /SUV ovary (P = 0.019, HR 2.321, 95% CI 1.148-4.692) were independent risk factors of recurrence. Patients with high SUV meta /SUV ovary showed a significantly worse PFS than those with low SUV meta /SUV ovary (P = 0.007, log-rank test). Preoperative SUV meta /SUV ovary was significantly associated with recurrence and has an incremental prognostic value for PFS in patients with advanced serous EOC. (orig.)

    The occurrence of drug resistance limits the efficacy of platinum compounds in the cure of ovarian carcinoma. Since microRNAs (miRNAs) may contribute to this phenomenon by regulating different aspects of tumor cell response, the aim of this study was to exploit the analysis of expression of miRNAs in platinum sensitive/resistant cells in an attempt to identify potential regulators of drug response. MiR-483-3p, which may participate in apoptosis and cell proliferation regulation, was found up-regulated in 4 platinum resistant variants, particularly in the IGROV-1/Pt1 subline, versus parental cells. Transfection of a synthetic precursor of miR-483-3p in IGROV-1 parental cells elicited a marked up-regulation of the miRNA levels. Growth-inhibition and colony-forming assays indicated that miR-483-3p over-expression reduced cell growth and conferred mild levels of cisplatin resistance in IGROV-1 cells, by interference with their proliferative potential. Predicted targets of miR-483-3p included PRKCA (encoding PKC-alpha), previously reported to be associated to platinum-resistance in ovarian carcinoma. We found that miR-483-3p directly targeted PRKCA in IGROV-1 cells. In keeping with this finding, cisplatin sensitivity of IGROV-1 cells decreased upon molecular/pharmacological inhibition of PKC-alpha. Overall, our results suggest that overexpression of miR-483-3p by ovarian carcinoma platinum-resistant cells may interfere with their proliferation, thus protecting them from DNA damage induced by platinum compounds and ultimately representing a drug-resistance mechanism. The impairment of cell growth may account for low levels of drug resistance that could be relevant in the clinical setting. - Highlights: • miR-483-3p is up-regulated in ovarian carcinoma cells resistant to platinum drugs. • Ectopic expression of miR-483-3p in IGROV-1 confers mild levels of Pt-resistance. • Overexpression of miR-483-3p down-regulates PRKCA levels in ovarian carcinoma cells. • miR 483

    The dynamic changes that occur in protein expression after treatment of a cancer in vivo are poorly described. In this study we measure the effect of chemotherapy over time on the expression of a panel of proteins in ovarian cancer xenograft models. The objective was to identify phosphoprotein and other protein changes indicative of pathway activation that might link with drug response. Two xenograft models, platinum-responsive OV1002 and platinum-unresponsive HOX424, were used. Treatments were carboplatin and carboplatin-paclitaxel. Expression of 49 proteins over 14 days post treatment was measured by quantitative immunofluorescence and analysed by AQUA. Carboplatin treatment in the platinum-sensitive OV1002 model triggered up-regulation of cell cycle, mTOR and DDR pathways, while at late time points WNT, invasion, EMT and MAPK pathways were modulated. Estrogen receptor-alpha (ESR1) and ERBB pathways were down-regulated early, within 24 h from treatment administration. Combined carboplatin-paclitaxel treatment triggered a more extensive response in the OV1002 model modulating expression of 23 of 49 proteins. Therefore the cell cycle and DDR pathways showed similar or more pronounced changes than with carboplatin alone. In addition to expression of pS6 and pERK increasing, components of the AKT pathway were modulated with pAKT increasing while its regulator PTEN was down-regulated early. WNT signaling, EMT and invasion markers were modulated at later time points. Additional pathways were also observed with the NFκB and JAK/STAT pathways being up-regulated. ESR1 was down-regulated as was HER4, while further protein members of the ERBB pathway were upregulated late. By contrast, in the carboplatin-unresponsive HOX 424 xenograft, carboplatin only modulated expression of MLH1 while carboplatin-paclitaxel treatment modulated ESR1 and pMET. Thirteen proteins were modulated by carboplatin and a more robust set of changes by carboplatin-paclitaxel. Early changes included

    Accurate preoperative staging of ovarian chocolate cysts is very important because recent hormonal therapy has been effective in low stage patients. However, it has been difficult to assess the preoperative stage of ovarian chocolate cysts. We evaluated the diagnostic potential of MRI in preoperative staging of 15 overian chocolate cysts. It was well known that the older the ovarian chocolate cyst was the more iron content it had. We examined the iron contents effect on T1 and T2 relaxation times in surgically confirmed chocolate cysts (stage II: 3 cases, stage III: 3 cases and stage IV: 9 cases by AFS classification, 1985) employing the 0.15-T MR system and 200 MHz spectrometer. There was a positive linear relation between T1 of the lesion using the MR system (T1) and T1 of the resected contents using the spectrometer (sp-T1); r = 0.93. The same relation was revealed between T2 and sp-T2; r = 0.87. It was indicated that T1 and T2 using the MR system was accurate. There was a negative linear relation between T1 and the iron contents ( r = -0.81) but no relation between T2 and the iron contents. T1 was 412 ± 91 msec for stage II, 356 ± 126 msec for stage III and 208 ± 30 msec for stage IV. T1 for stage IV was shorter than that for stage II and III, statistically significant differences were noted (p < 0.05). Thus, T1 was useful in differentiating a fresh from an old ovarian chocolate cyst. We concluded that T1 relaxation time using the MR system was useful for the staging of an ovarian chocolate cyst without surgery. (author)

    The natural history of advanced-stage epithelial ovarian cancer is one of clinical remission after surgery and platinum/taxane-based intravenous (IV) and/or intraperitoneal (IP) chemotherapy followed by early or late recurrence in the majority of patients. Prevention of progression and recurrence remains a major hurdle in the management of ovarian cancer. Recently, many investigators have evaluated the use of normothermic and hyperthermic intraoperative IP drug delivery as a management strategy. This is a narrative review of the current status of clinical trials of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in ovarian cancer and the future directions for this treatment strategy. The existing studies on HIPEC in patients with epithelial ovarian cancer are mostly retrospective in nature, are heterogeneous with regards to combined inclusion of primary and recurrent disease and lack unbiased data. Until data are available from evidence-based trials, it is reasonable to conclude that surgical cytoreduction and HIPEC is a rational and interesting, though still investigative, approach in the management of epithelial ovarian cancer, whose use should be employed within prospective clinical trials.

    Full Text Available The cancer stem cell (CSC hypothesis postulates that cancer cells are composed of hierarchically-organized subpopulations of cells with distinct phenotypes and tumorigenic capacities. As a result, CSCs have been suggested as a source of disease recurrence. Recently, silver nanoparticles (AgNPs have been used as antimicrobial, disinfectant, and antitumor agents. However, there is no study reporting the effects of AgNPs on ovarian cancer stem cells (OvCSCs. In this study, we investigated the cytotoxic effects of AgNPs and their mechanism of causing cell death in A2780 (human ovarian cancer cells and OvCSCs derived from A2780. In order to examine these effects, OvCSCs were isolated and characterized using positive CSC markers including aldehyde dehydrogenase (ALDH and CD133 by fluorescence-activated cell sorting (FACS. The anticancer properties of the AgNPs were evaluated by assessing cell viability, leakage of lactate dehydrogenase (LDH, reactive oxygen species (ROS, and mitochondrial membrane potential (mt-MP. The inhibitory effect of AgNPs on the growth of ovarian cancer cells and OvCSCs was evaluated using a clonogenic assay. Following 1–2 weeks of incubation with the AgNPs, the numbers of A2780 (bulk cells and ALDH+/CD133+ colonies were significantly reduced. The expression of apoptotic and anti-apoptotic genes was measured by real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR. Our observations showed that treatment with AgNPs resulted in severe cytotoxicity in both ovarian cancer cells and OvCSCs. In particular, AgNPs showed significant cytotoxic potential in ALDH+/CD133+ subpopulations of cells compared with other subpopulation of cells and also human ovarian cancer cells (bulk cells. These findings suggest that AgNPs can be utilized in the development of novel nanotherapeutic molecules for the treatment of ovarian cancers by specific targeting of the ALDH+/CD133+ subpopulation of cells.

    Ovarian cancer is the leading cause of death of all gynaecological cancers. To date, there is no reliable, specific screening procedure for detecting ovarian cancer. The risk factors of ovarian cancer include modifiable and non-modifiable factors. The main goal of the ovarian cancer prevention program is to significantly reduce the risk of development of ovarian cancer and other cancers such as breast and/or peritoneal cancer. The application of non-surgical preventive approaches such as oral contraceptives, parity and breastfeeding has been shown to be highly protective against ovarian cancer development. Targeting inflammation has been also reported to be associated with a protective trend against ovarian cancer and can be achieved through either non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin or lifestyle modifications or both. Lifestyle modification that includes regular exercise, healthy diet supplemented with anti-oxidants and anti-inflammatory elements reduces the risk of the disease even further. Surgical protective approaches include; tubal ligation, hysterectomy and prophylactic bilateral salpingo-oophorectomy and the former is the most effective approach to protect against ovarian cancer. A better understanding of the risk factors of ovarian cancer and the current approaches to prevent it may increase the awareness and help to decrease the incidence of ovarian cancer, increase the five-year survival rate and decrease the mortality rate significantly in the general population especially among those at high risk for ovarian cancer. This review is an attempt to outline a potential program of ovarian cancer prevention and the potential challenges.

    The human major vault protein (MVP) has been linked to the development of multidrug resistance in cancer cells, and overexpression of MVP has been observed in ovarian cancer tissues. The aim of the present study was to investigate the association between single nucleotide polymorphisms (SNPs) in the MVP gene and the tumor response to platinum-based chemotherapy and survival of patients affected by epithelial ovarian cancer (EOC), in addition to confirm whether tetra-primer amplification-refractory mutation system (ARMS)-polymerase chain reaction (PCR) is an accurate genotyping method. For this purpose, two polymorphisms in the MVP gene, namely reference SNP (rs)1057451 and rs4788186, were selected from the data obtained by the International haplotype map (HapMap) Project regarding Chinese Han population, and were evaluated by tetra-primer ARMS-PCR. Upon validation by DNA sequencing, the association of these polymorphisms with platinum resistance, progression-free survival (PFS) and overall survival (OS) in patients with EOC was assessed. The results of tetra-primer ARMS-PCR were in agreement with those derived from DNA sequencing. No significant differences were observed between platinum-sensitive and platinum-resistant cohorts in terms of allele and genotype distribution of these two polymorphisms in the MVP gene, which were not associated with PFS or OS. However, a trend toward prolonged PFS was observed in patients carrying the heterozygous AG allele at the rs4788186 locus. These results suggest that rs1057451 and rs4788186 variants in the MVP gene are not associated with favorable therapeutic response to platinum or longer survival in Chinese Han patients affected by EOC. In addition, the data of the present study confirm that tetra-primer ARMS-PCR is a trustworthy and economical genotyping method.

    Full Text Available Ovarian cancer is the most lethal of all gynecological malignancies, due in part to the diagnosis at an advanced stage caused by the lack of specific signs and symptoms and the absence of reliable tests for screening and early detection. Most patients will respond initially to treatment but about 70% of them will suffer a recurrence. Therefore, new therapeutic modalities are urgently needed to overcome chemoresistance observed in ovarian cancer patients. Evidence accumulates suggesting that the insulin/insulin growth factor (IGF pathways could act as a good therapeutic target in several cancers, including ovarian cancer. In this paper, we will focus on the role of insulin/IGF in ovarian cancer tumorigenesis and treatment.

    Full Text Available Ovarian cysts are the most common cause of pelvic masses in women. Although laparoscopic surgery is considered the gold standard treatment for ovarian cysts, most of the large ovarian cysts continue to be treated by laparotomy due to technical difficulties. Laparoscopic-assisted cystectomy is an alternative operation type for managing such cases. A case of large ovarian cyst with adnexal torsion in a 21-year-old virgin patient is presented in this report. In this case laparoscopic-assisted cystectomy was performed without intraoperatif complication. Postoperative course was uneventful. Pathology revealed a benign serous cystadenoma. At 6 months follow up, she continued to be asymptomatic, and sonography showed no recurrence of her disease. Laparoscopic-assisted cystectomy is a safe and effective procedure for large adnexal cysts.

  20. Ovarian hormones and obesity.

    2017-05-01

    Obesity is caused by an imbalance between energy intake, i.e. eating and energy expenditure (EE). Severe obesity is more prevalent in women than men worldwide, and obesity pathophysiology and the resultant obesity-related disease risks differ in women and men. The underlying mechanisms are largely unknown. Pre-clinical and clinical research indicate that ovarian hormones may play a major role. We systematically reviewed the clinical and pre-clinical literature on the effects of ovarian hormones on the physiology of adipose tissue (AT) and the regulation of AT mass by energy intake and EE. Articles in English indexed in PubMed through January 2016 were searched using keywords related to: (i) reproductive hormones, (ii) weight regulation and (iii) central nervous system. We sought to identify emerging research foci with clinical translational potential rather than to provide a comprehensive review. We find that estrogens play a leading role in the causes and consequences of female obesity. With respect to adiposity, estrogens synergize with AT genes to increase gluteofemoral subcutaneous AT mass and decrease central AT mass in reproductive-age women, which leads to protective cardiometabolic effects. Loss of estrogens after menopause, independent of aging, increases total AT mass and decreases lean body mass, so that there is little net effect on body weight. Menopause also partially reverses women's protective AT distribution. These effects can be counteracted by estrogen treatment. With respect to eating, increasing estrogen levels progressively decrease eating during the follicular and peri-ovulatory phases of the menstrual cycle. Progestin levels are associated with eating during the luteal phase, but there does not appear to be a causal relationship. Progestins may increase binge eating and eating stimulated by negative emotional states during the luteal phase. Pre-clinical research indicates that one mechanism for the pre-ovulatory decrease in eating is a

    This review article summarizes the role of PET/CT and PET/MRI in ovarian cancer. With regard to the diagnosis of ovarian cancer, the presence of FDG uptake within the ovary of a postmenopausal woman raises the concern for ovarian cancer. Multiple studies show that FDG PET/CT can detect lymph node and distant metastasis in ovarian cancer with high accuracy and may, therefore, alter the management to obtain better clinical outcomes. Although PET/CT staging is superior for N and M staging of ovarian cancer, its role is limited for T staging. Additionally, FDG PET/CT is of great benefit in evaluating treatment response and has prognostic value in patients with ovarian cancer. FDG PET/CT also has value to detect recurrent disease, particularly in patients with elevated serum CA-125 levels and negative or inconclusive conventional imaging test results. PET/MRI may beneficial for tumor staging because MRI has higher soft tissue contrast and no ionizing radiation exposure compared to CT. Some non-FDG PET radiotracers such as 18 F-fluorothymidine (FLT) or 11 C-methionine (MET) have been studied in preclinical and clinical studies as well and may play a role in the evaluation of patients with ovarian cancer.

    Ovarian cancer, the most lethal gynecological cancer, related closely to tumor stage. High-grade ovarian cancer always results in a late diagnose and high recurrence, which reduce survival within five years. Until recently, curable therapy is still under research and anti-angiogenesis proves a promising way. Tumor-derived exosomes are essential in tumor migration and metastases such as angiogenesis is enhanced by exosomes. In our study, we have made comparison between high-grade and unlikely high-grade serous ovarian cancer cells on exosomal function of endothelial cells proliferation, migration and tube formation. Exosomes derived from high-grade ovarian cancer have a profound impact on angiogenesis with comparison to unlikely high-grade ovarian cancer. Proteomic profiles revealed some potential proteins involved in exosomal function of angiogenesis such as ATF2, MTA1, ROCK1/2 and so on. Therefore, exosomes plays an influential role in angiogenesis in ovarian serous cancer and also function more effectively in high-grade ovarian cancer cells.

FDG PET/CT also has value to detect recurrent disease, particularly in patients with elevated serum CA-125 levels and negative or inconclusive conventional imaging test results. PET/MRI may beneficial for tumor staging because MRI has higher soft tissue contrast and no ionizing radiation exposure compared to CT. Some non-FDG PET radiotracers such as {sup 18}F-fluorothymidine (FLT) or {sup 11}C-methionine (MET) have been studied in preclinical and clinical studies as well and may play a role in the evaluation of patients with ovarian cancer.

    Objective: To evaluate the significance of monitoring serum sex hormones levels after ovarian tissue auto-transplantation. Methods: Twenty-five patients with stage IV recurrent endometriosis after one or two times of conservative surgeries underwent radical surgery. Their ovarian tissue fragments were transplanted to greater omentum. Serum follicle-stimulation hormone (FSH), Luteinizing hormone (LH) and estradiol (E 2 ) levels were measured monthly since fourth month post-operatively. After E 2 was increased, based body temperature was measured and vaginal hormone cytology was examined weekly for maturation index (MI) to assess the ovulatory phase and luteal phase in those with viable ovarian tissues. Serum levels of FSH, LH and E 2 in ovulatory phase and luteal phase were determined 20 women with viable ovarian tissues for three cycles as well as in 20 normal sexually mature women and 20 operative menopausal women. Results: There were 12 cases who had increasing of E 2 at four months post operatively and 8 cases more at six months. The other 5 cases with low serum E 2 levels and high FSH and LH levels at 12 months were designated as failures. The survival rate of transplanted ovarian tissue was 80.0%. There were no significant differences of the serum FSH, LH and E 2 levels in ovulatory phase and luteal phase between women with viable grafted ovarian tissues and normal sexually mature women. Conclusion: Monitoring of sex hormones is a good means to assess the viability of the transplanted ovarian tissue fragments

    To compare the clinicopathologic features and prognosis of Chinese patients with ovarian clear cell carcinoma (CCC) and serous carcinoma (SC). A retrospective cohort study was designed to investigate the clinicopathologic characteristic and prognosis of patients with CCC and SC who were diagnosed and treated in in a tertiary referral center (Peking Union Medical College Hospital) between 1999 and 2009. The Kaplan-Meier method and Cox regression were employed in the survival analysis. A total of 504 cases were included in the study, comprising 197 cases of CCC and 307 cases of SC. The mean age of the patients with SC was greater than of CCC patients (3.6±0.94, PPatients with CCC were more likely to be early-stage and optimally debulked (Ppatients with CCC had normal values, and the level was significantly lower than in patients with SC (Ppatients had platinum-resistant tumors compared with platinum-sensitive disease (45.7% in CCC vs. 61.0% in SC [P=0.008]). The 5-year survival rate was 51.2% in the CCC group vs. 49.8% in the SC group (P=0.428). Patients with advanced CCC had a statistically significant poorer overall survival (OS) compared with their SC counterparts (38.0 vs. 52.0 months; hazard ratio 1.584, 95% confidence interval [CI] 1.167-2.150, P=0.003). However, the advantage of improved progression-free survival (PFS) existed across all stages. Women with ovarian CCC presented at a younger age and early stage. Patients with ovarian CCC also had improved PFS, but they had similar OS compared to patients with SC. However, patients with advanced CCC had decreased survival.

    Preventive breast surgery and MRI screening are offered to unaffected BRCA mutation carriers. The clinical benefit of these two modalities has not been evaluated among mutation carriers with a history of ovarian cancer. Thus, we sought to determine whether or not BRCA mutation carriers with ovarian cancer would benefit from preventive mastectomy or from MRI screening. First, the annual mortality rate for ovarian cancer patients was estimated for a cohort of 178 BRCA mutation carriers from Ontario, Canada. Next, the actuarial risk of developing breast cancer was estimated using an international registry of 509 BRCA mutation carriers with ovarian cancer. A series of simulations was conducted to evaluate the reduction in the probability of death (from all causes) associated with mastectomy and with MRI-based breast surveillance. Cox proportional hazards models were used to evaluate the impacts of mastectomy and MRI screening on breast cancer incidence as well as on all-cause mortality. Twenty (3.9%) of the 509 patients developed breast cancer within ten years following ovarian cancer diagnosis. The actuarial risk of developing breast cancer at ten years post-diagnosis, conditional on survival from ovarian cancer and other causes of mortality was 7.8%. Based on our simulation results, among all BRCA mutation-carrying patients diagnosed with stage III/IV ovarian cancer at age 50, the chance of dying before age 80 was reduced by less than 1% with MRI and by less than 2% with mastectomy. Greater improvements in survival with MRI or mastectomy were observed for women who had already survived 10years after ovarian cancer, and for women with stage I or II ovarian cancer. Among BRCA mutation-carrying ovarian cancer patients without a personal history of breast cancer, neither preventive mastectomy nor MRI screening is warranted, except for those who have survived ovarian cancer without recurrence for ten years and for those with early stage ovarian cancer.

    Full Text Available Aims: Primary cysts and tumors of the ovary alongwith torsion are often regarded as an indication for open oophorectomy because of the fear of leaving an ischemic organ inside and chances of recurrence. We wish to report our experience of both modalities of management where we initially removed adenexal torsion by either laparoscopic salpingo-oophorectomy or oophorectomy, but later followed a more conservative approach of adenexal lesion removal with ovarian preservation. Materials and Methods: Retrospective review of clinical records of patients with ovarian pathology who were managed laparoscopically. Results: 46 cases of pediatric ovarian pathology were managed between March 2006 and March 2013 in two centers by a team of surgeons. The age ranged from 1 days to 18 years (average 14.3 years and the pathology varied from 30 cases of a simple ovarian cyst with torsion, 3 cases of ovarian torsion without any cyst, 7 cases of a dermoid cyst with torsion in all, 1 case of secreting ovarian tumor and 5 cases of a paraovarian cyst with torsion. All patients had a normal tumor marker except 1 girl with a functional ovarian tumor who had elevated LDH and estrogen levels alongwith suppressed LH and FSH. In the initial period of our study we did 1 salpingo-oophorectomy for a suspected complex lesion and two oophorectomies for torsion with a simple cyst. In the later part of our study we performed laparoscopic cystectomy and ovarian preservation in 40 cases, including 7 cases of dermoid, where we performed laparoscopic detorsion with dermoid cystectomy and ovarian preservation in the same sitting. In three cases of chronic torsion who presented to us late, we could not preserve the ovary and had to resort to salpingo-ophorectomy. Histology showed a simple corpus luteal and follicular ovarian cyst in 31 cases, a paraovarian cyst in 5 cases with mature teratoma in 7 cases. Twenty-five patients with ovarian preservation following detorsion were subjected to

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

    Full Text Available Actinomycotic infection of the female genital tract is rare. Actinomycosis is a chronic suppurative granulomatous infection that is characterized by formation of abscesses, multiple draining sinuses and appearance of tangled mycelial masses or granules in the discharges and tissue sections. 2 cases of tubo-ovarian actinomycosis are reported. The 1st case presented clinical with gastrointestinal symptoms and a ventral scar hernia following an operation for a non-healing abdominal wound 6 months earlier. The 2nd case sought medical attention for backache and leucorrhea of 4 years′ duration. Exploratory laparotomy in the 1st case revealed tubo-ovarian masses; the vermiform appendix was not traceable. The uterine cavity in the 2nd case harbored a wooden stick. Direct extension from established ileocacal actinomycosis was believed to involve the female genital adnexae in the past. Association of tubo-ovarian actinomycosis with the presence of a foreign body in the female genital tract has been reported sporadically in the literature, yet an increase in the incidence may be expected because of the frequent use of intrauterine contraceptive devices in recent times. It is suggested that in women presenting clinically with vague abdominal symptoms, backache and discharge, actinomycosis should be considered and ruled out with the help of cytologic and proper microbial culture methods. Once the diagnosis is established, the infection can be treated with good results with penicillin.

    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.

    The response rate of ovarian mucinous carcinomas to paclitaxel/carboplatin is low, prompting interest in targeted molecular therapies. We investigated HER2 expression and amplification, and the potential for trastuzumab therapy in this histologic subtype of ovarian cancer. HER2 status was tested in 33 mucinous carcinomas and 16 mucinous borderline ovarian tumors (BOT)). Five cases with documented recurrence and with tissue from the recurrence available for testing were analyzed to determine whether HER2 amplification status changed over time. Three prospectively identified recurrent mucinous ovarian carcinomas were assessed for HER2 amplification and patients received trastuzumab therapy with conventional chemotherapy. Amplification of HER2 was observed in 6/33 (18.2%) mucinous carcinomas and 3/16 (18.8%) BOT. HER2 amplification in primary mucinous carcinomas was not associated with an increased likelihood of recurrence. The prospectively identified recurrent mucinous carcinomas showed overexpression and amplification of HER2; one patient's tumor responded dramatically to trastuzumab in combination with conventional chemotherapy, while another patient experienced an isolated central nervous system recurrence after trastuzumab therapy. HER2 amplification is relatively common in ovarian mucinous carcinomas (6/33, 18.2%), although not of prognostic significance. Trastuzumab therapy is a treatment option for patients with mucinous carcinoma when the tumor has HER2 amplification and overexpression

    Resistance to platinum-based chemotherapy remains a major impediment in the treatment of serous epithelial ovarian cancer. The objective of this study was to use gene expression profiling to delineate major deregulated pathways and biomarkers associated with the development of intrinsic chemotherapy resistance upon exposure to standard first-line therapy for ovarian cancer. The study cohort comprised 28 patients divided into two groups based on their varying sensitivity to first-line chemotherapy using progression free survival (PFS) as a surrogate of response. All 28 patients had advanced stage, high-grade serous ovarian cancer, and were treated with standard platinum-based chemotherapy. Twelve patient tumours demonstrating relative resistance to platinum chemotherapy corresponding to shorter PFS (< eight months) were compared to sixteen tumours from platinum-sensitive patients (PFS > eighteen months). Whole transcriptome profiling was performed using an Affymetrix high-resolution microarray platform to permit global comparisons of gene expression profiles between tumours from the resistant group and the sensitive group. Microarray data analysis revealed a set of 204 discriminating genes possessing expression levels which could influence differential chemotherapy response between the two groups. Robust statistical testing was then performed which eliminated a dependence on the normalization algorithm employed, producing a restricted list of differentially regulated genes, and which found IGF1 to be the most strongly differentially expressed gene. Pathway analysis, based on the list of 204 genes, revealed enrichment in genes primarily involved in the IGF1/PI3K/NF κB/ERK gene signalling networks. This study has identified pathway specific prognostic biomarkers possibly underlying a differential chemotherapy response in patients undergoing standard platinum-based treatment of serous epithelial ovarian cancer. In addition, our results provide a pathway context for

    Full Text Available Leticia Cox, James H LiuUH Case Medical Center, MacDonald Women's Hospital, Department of Obstetrics and Gynecology, Case Western Reserve University School of Medicine, Department of Reproductive Biology, Cleveland, OH, USAAbstract: 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.Keywords: premature ovarian failure, premature menopause, ovarian dysfunction

    A major burden in the treatment of ovarian cancer is the high percentage of recurrence and chemoresistance. Cancer stem cells (CSCs) provide a reservoir of cells that can self-renew, can maintain the tumor by generating differentiated cells [non-stem cells (non-CSCs)] which make up the bulk...... to form spheroids in suspension, and the ability to recapitulate in vivo the original tumor. Chemotherapy eliminates the bulk of the tumor but it leaves a core of cancer cells with high capacity for repair and renewal. The molecular properties identified in these cells may explain some of the unique...... of the tumor and may be the primary source of recurrence. We describe the characterization of human ovarian cancer stem cells (OCSCs). These cells have a distinctive genetic profile that confers them with the capacity to recapitulate the original tumor, proliferate with chemotherapy, and promote recurrence...

    Full Text Available Ovarian cancer is the foremost cause of gynecological cancer death in the developed world, as it is usually diagnosed at an advanced stage. In this paper we discuss current issues, the efficacy and problems associated with ovarian cancer screening, and compare the characteristics of ovarian cancer subtypes. There are two types of ovarian cancer: Type I carcinomas, which are slow-growing, indolent neoplasms thought to arise from a precursor lesion, which are relatively common in Asia; and Type II carcinomas, which are clinically aggressive neoplasms that can develop de novo from serous tubal intraepithelial carcinomas (STIC and/or ovarian surface epithelium and are common in Europe and the USA. One of the most famous studies on the subject reported that annual screening using CA125/transvaginal sonography (TVS did not reduce the ovarian cancer mortality rate in the USA. In contrast, a recent study in the UK showed an overall average mortality reduction of 20% in the screening group. Another two studies further reported that the screening was associated with decreased stage at detection. Theoretically, annual screening using CA125/TVS could easily detect precursor lesions and could be more effective in Asia than in Europe and the USA. The detection of Type II ovarian carcinoma at an early stage remains an unresolved issue. The resolving power of CA125 or TVS screening alone is unlikely to be successful at resolving STICs. Biomarkers for the early detection of Type II carcinomas such as STICs need to be developed.

    The human leukocyte antigen (HLA)-G and HLA-E, non classical HLA class I molecules, have been highly implicated in immune tolerance. HLA-G and HLA-E molecules were proposed as putative markers of several advanced cancers. As a step towards a better understanding of ovarian carcinoma, we evaluated the expression of both HLA-G and HLA-E molecules and explored their prognostic implication. HLA-G and HLA-E expression were studied by immunohistochemistry on ovarian carcinoma tissues. This expression was semi-quantitatively scored into four expression groups and correlated to clinicopathological parameters and patients' survival. HLA-G and HLA-E have been found to be highly expressed in ovarian carcinoma tissues (Respectively, 72.4% and 96.8%). They are frequently co-expressed. Univariate and multivariate analysis revealed that a positive HLA-G expression status in tumor tissue is a promising candidate parameter to predict disease recurrence in addition to the disease status in Tunisian patients with ovarian carcinoma. Moreover, the elevated HLA-E expression was associated with serous ovarian carcinoma subtype as well as with advanced stages of ovarian carcinoma. HLA-G and HLA-E are highly represented in ovarian carcinoma suggesting a potential association with progressive disease mechanism. HLA-G and HLA-E molecules might be new candidates' markers for ovarian carcinoma progression. Copyright © 2018 American Society for Histocompatibility and Immunogenetics. Published by Elsevier Inc.

    Epithelial ovarian carcinoma is the most lethal gynecological cancer due to its silent onset and recurrence with resistance to chemotherapy. Overexpression of oncogene c-Myc is one of the most frequently encountered events present in ovarian carcinoma. Disrupting the function of c-Myc and its downstream target genes is a promising strategy for cancer therapy. Our objective was to evaluate the potential effects of small-molecule c-Myc inhibitor, 10058-F4, on ovarian carcinoma cells and the underlying mechanisms by which 10058-F4 exerts its actions. Using MTT assay, colony formation, flow cytometry and Annexin V FITC assays, we found that 10058-F4 significantly inhibited cell proliferation of both SKOV3 and Hey ovarian cancer cells in a dose dependent manner through induction of apoptosis and cell cycle G1 arrest. Treatment with 10058-F4 reduced cellular ATP production and ROS levels in SKOV3 and Hey cells. Consistently, primary cultures of ovarian cancer treated with 10058-F4 showed induction of caspase-3 activity and inhibition of cell proliferation in 15 of 18 cases. The response to 10058-F4 was independent the level of c-Myc protein over-expression in primary cultures of ovarian carcinoma. These novel findings suggest that the growth of ovarian cancer cells is dependent upon c-MYC activity and that targeting c-Myc-Max heterodimerization could be a potential therapeutic strategy for ovarian cancer.

    The method of ultrasonography is high informative and widely used in diagnostics of ovarian hyperandrogenaemia. The majority of authors consider that a hyperplasia of a stroma is the main pathognomonic marker of polycystic ovaries (PCO). Still recently swell of a stroma was valued visually, that had subjective nature. We offer for the first time a way of diagnostics of stromal hyperplasia grounded on measurement of a volume of a stroma and ovary with ultrasound method, calculation of the ratio of a volume of the ovary to a volume of a stroma for every patient.

    Full Text Available Stonin 2 (STON2, which functions in adjusting endocytotic complexes, is probably involved in the monitoring of the internalization of dopamine D2 receptors which have an inhibitory action of dopamine on tumor progression. However, its clinical significance in tumor progression and prognosis remains unclear. We explored the association between STON2 and the clinicopathological characteristics of epithelial ovarian cancer (EOC. The STON2 levels in ovarian cancer and normal cell lines and tissues were detected by real-time PCR and Western blot analyses. STON2 protein expression was also detected by an immunohistochemical analysis. The clinical significance of STON2 expression in ovarian cancer was statistically analyzed. STON2 significantly increased in the ovarian cancer cell lines and tissues compared to the normal ones. In the 89 EOC samples tested, STON2 expression was significantly correlated with intraperitoneal metastasis, intestinal metastasis, intraperitoneal recurrence, ascites containing tumor cells, and CA153 level. Moreover, patients with STON2 protein overexpression were more likely to exhibit platinum resistance and to have undergone neoadjuvant chemotherapy. Patients with high STON2 protein expression had a tendency to have a shorter overall survival and a poor prognosis. A multivariate analysis showed that STON2 was an independent prognostic predictor for EOC patients. In conclusion, STON2 plays an important role in the progression and prognosis of ovarian carcinoma, especially in platinum resistance, intraperitoneal metastasis, and recurrence. STON2 can be a novel antitumor drug target and biomarker which predicts an unfavorable prognosis for EOC patients.

    The aetiology of ovarian cancer is multifactorial with both endogenous and exogenous risk factors playing an important role. The exact pathogenesis of ovarian cancer is still not well understood, despite the number of hypotheses published. Due to an increase in the number of women using fertility drugs, much attention has been focused on the long-term health effects of such drugs. Although fertility drugs facilitate the ovulation process, it is however associated with a significant increase in hormone concentrations, placing exposed women at increased risk of gynaecological cancer. Many clinical and epidemiological studies have examined the association between fertility drugs and ovarian cancer risk. Results from these studies have been contradictory, as some studies have reported an increased risk of ovarian cancer while others reported no increased risk. Nevertheless, recent studies have shown that women who used fertility drugs and did not conceive had a higher risk of developing ovarian cancer, compared to women who used fertility drugs and conceived and delivered successfully. This review discusses the effect of fertility drugs on the risk of developing ovarian cancer, providing details on four possible scenarios associated with fertility treatment. In addition, the limitations of previous studies and their impact on our understanding of the association between fertility drugs and ovarian cancer also have been highlighted.

    To evaluate percutaneous short-term catheter drainage in the management of benign ovarian cysts in patients at increased surgical risk. Thirty-eight patients with simple ovarian cysts were treated with drainage of fluid content by catheters until output stopped. All patients were poor candidates for surgery. All procedures were performed under ultrasonographic (US) control and local anesthesia. Cytologic examination was performed in all cases. The patients were followed up monthly with color Doppler US for 12 months. Outcome measure was the recurrence of a cyst. During the 12-month follow-up period, 10 of 38 cysts recurred. Seven of the 10 cysts required further intervention, and three were followed up without intervention. Four of the seven patients who required further intervention underwent repeat transabdominal aspiration and three declined repeat aspiration and subsequently underwent surgery. After repeated aspirations, two of four cysts disappeared, one necessitated follow-up only, and one necessitated surgical intervention. Cyst volume (P = .009) and diameter (P = .001) were significantly larger in the cysts that recurred. No evidence of malignancy was reported in the cytologic examination in any patient. No patients developed malignancy during follow-up. No major complications were observed. The hospital stay was 1 day for all patients. The median duration of drainage in the groups with resolved and recurrent cysts was 1 day (interquartile range, 1-1) and 2 days (interquartile range, 1-3), respectively (P = .04). In patients considered poor candidates for open surgery or laparoscopy, percutaneous treatment of ovarian cysts with short-term catheter drainage without sclerotherapy appears to be a safe and effective alternative, with low recurrence rates.

  9. Multimodal treatment combining chemotherapy, hyperthermia and radiotherapy for ovarian cancer

    There has been increasing interest in the use of heat in the treatment of cancer. Theoretically cells are the most sensitive to ionizing radiation at mitosis, whereas the cycle phase that is the most resistant to ionizing radiation namely late in the DNA. Synthetic phase (late S) is the most sensitive to hyperthermia. Hyperthermia has been reported to enhance the cytocidal effects of several active chemotherapeutic agents. When thermal potentiation of chemotherapeutic agents against malignant cells is contemplated, normal tissues have a relatively high ambient blood flow which increases in response to thermal stress, thereby dissipating heat, compared to tumors. Tumors, with relatively poor blood flow and a responsive neovasculature, are in capable of augmenting flow and acting as a heat reservoir. This is the phenomenon of a heat reservoir which is one factor to enhance the cytocidal effects of several active anticancer agents for enhancing the uptake in tumor. The importance is in the adjuvant chemotherapy treated for post operative, advanced and recurrent ovarian cancer. Heating enhances the effects of radiotherapy and chemotherapy. Thirty patients with ovarian cancer were subjected to the multidisciplinary treatment with combination of hyperthermochemotherapy and radiation. The 30 patients consisted of 18 with endometrioid adenocarcinoma and 7 with serious post operative or recurrent status. Two types of equipments with rediofrequencies of 70 MHz (BSD-1000) or 434 MHZ (TAG MED·HS 434) were used for hyperthermia. Chemotherapeutic agents such as adriamycin, cis DDP, cyclophosphamide and etoposide were injected intravenously. Arterial infusion with reservoir was very effective in advanced stage of ovarian cancer. No severe or fatal side effects were observed. Hyperthermochemotherapy is useful and effective for the postoperative management or the treatment of recurrent cancer of the ovary. (J.P.N.)

    Full Text Available Abstract Ovarian cancer continues to be the most lethal of the gynaecologic malignancies due to the lack of early detection, screening strategies and ineffective therapeutics for late-stage metastatic disease, particularly in the recurrent setting. The gathering of researchers investigating fundamental pathobiology of ovarian cancer and the clinicians who treat patients with this insidious disease is paramount to meeting the challenges we face. Since 2002, the Canadian Conference on Ovarian Cancer Research, held every two years, has served this essential purpose. The objectives of this conference have been to disseminate new information arising from the most recent ovarian cancer research and identify the most pressing challenges we still face as scientists and clinicians. This is best accomplished through direct encounters and exchanges of innovative ideas among colleagues and trainees from the realms of basic science and clinical disciplines. This meeting has and continues to successfully facilitate rapid networking and establish new collaborations from across Canada. This year, more guest speakers and participants from other countries have extended the breadth of the research on ovarian cancer that was discussed at the meeting. This report summarizes the key findings presented at the fifth biennial Canadian Conference on Ovarian Cancer Research held in Toronto, Ontario, and includes the important issues and challenges we still face in the years ahead to make a significant impact on this devastating disease.

  11. Copy number variation analysis of matched ovarian primary tumors and peritoneal metastasis.

    Full Text Available Ovarian cancer is the most deadly gynecological cancer. The high rate of mortality is due to the large tumor burden with extensive metastatic lesion of the abdominal cavity. Despite initial chemosensitivity and improved surgical procedures, abdominal recurrence remains an issue and results in patients' poor prognosis. Transcriptomic and genetic studies have revealed significant genome pathologies in the primary tumors and yielded important information regarding carcinogenesis. There are, however, few studies on genetic alterations and their consequences in peritoneal metastatic tumors when compared to their matched ovarian primary tumors. We used high-density SNP arrays to investigate copy number variations in matched primary and metastatic ovarian cancer from 9 patients. Here we show that copy number variations acquired by ovarian tumors are significantly different between matched primary and metastatic tumors and these are likely due to different functional requirements. We show that these copy number variations clearly differentially affect specific pathways including the JAK/STAT and cytokine signaling pathways. While many have shown complex involvement of cytokines in the ovarian cancer environment we provide evidence that ovarian tumors have specific copy number variation differences in many of these genes.

    To evaluate the prognostic value of metabolic activity of metastatic lesions measured by {sup 18}F-flurodeoxyglucose ({sup 18}F-FDG) uptake on preoperative positron emission tomography/computed tomography (PET/CT) in patients with advanced serous epithelial ovarian cancer (EOC). Clinico-pathological variables and PET/CT parameters such as the maximum standardised uptake value of the ovarian cancer (SUV{sub ovary}), metastatic lesions (SUV{sub meta}), and the metastatic lesion-to-ovarian cancer standardised uptake value ratio (SUV{sub meta}/SUV{sub ovary}) were assessed in International Federation of Gynaecology and Obstetrics (FIGO) stage III, IV patients. Clinico-pathological data were retrospectively reviewed for 94 eligible patients. The median progression-free survival (PFS) was 18.5 months (range, 6-90 months), and 57 (60.6%) patients experienced recurrence. Older age [P = 0.017, hazard ratio (HR) 1.036, 95% CI 1.006-1.066], residual disease after surgery (P = 0.024, HR 1.907, 95% CI 1.087-3.346), and high SUV{sub meta}/SUV{sub ovary} (P = 0.019, HR 2.321, 95% CI 1.148-4.692) were independent risk factors of recurrence. Patients with high SUV{sub meta}/SUV{sub ovary} showed a significantly worse PFS than those with low SUV{sub meta}/SUV{sub ovary} (P = 0.007, log-rank test). Preoperative SUV{sub meta}/SUV{sub ovary} was significantly associated with recurrence and has an incremental prognostic value for PFS in patients with advanced serous EOC. (orig.)

    To evaluate endocrine and ovulatory changes in polycystic ovarian disease (PCOD) in relation to patients' ovarian size. Three hundred and seventy-one women with clomiphene citrate-resistant PCOD underwent laparoscopic ovarian cauterization [type I or typical with ovarian volume >8 cm(3) or cross-sectional area >10 cm(2) (n=211), type II with normal size ovary (n=160)]. Serum levels of LH, FSH, DHEAS, PRL, and T before and 10 days after ovarian cautery, spontaneous and induced ovulation and pregnancy rates were compared. Both groups responded to therapy in a similar manner, with a marked decrease in LH, FSH, DHEAS and T levels, with ovulation rates in type I 90.99%, type II 88.75% and pregnancy rates, 73.45% and 71.25%, respectively, with no statistical differences. Hormonal changes, ovulation and pregnancy rates were similar in the two types of PCOD, therefore it can be concluded that ovarian size is not a prognostic factor for response of PCOD patients to laparoscopic ovarian electro-cauterization.

    Full Text Available Identification of families at risk for ovarian cancer offers the opportunity to consider prophylactic surgery thus reducing ovarian cancer mortality. So far, identification of potentially affected families in Germany was solely performed via family history and numbers of affected family members with breast or ovarian cancer. However, neither the prevalence of deleterious variants in BRCA1/2 in ovarian cancer in Germany nor the reliability of family history as trigger for genetic counselling has ever been evaluated.Prospective counseling and germline testing of consecutive patients with primary diagnosis or with platinum-sensitive relapse of an invasive epithelial ovarian cancer. Testing included 25 candidate and established risk genes. Among these 25 genes, 16 genes (ATM, BRCA1, BRCA2, CDH1, CHEK2, MLH1, MSH2, MSH6, NBN, PMS2, PTEN, PALB2, RAD51C, RAD51D, STK11, TP53 were defined as established cancer risk genes. A positive family history was defined as at least one relative with breast cancer or ovarian cancer or breast cancer in personal history.In total, we analyzed 523 patients: 281 patients with primary diagnosis of ovarian cancer and 242 patients with relapsed disease. Median age at primary diagnosis was 58 years (range 16-93 and 406 patients (77.6% had a high-grade serous ovarian cancer. In total, 27.9% of the patients showed at least one deleterious variant in all 25 investigated genes and 26.4% in the defined 16 risk genes. Deleterious variants were most prevalent in the BRCA1 (15.5%, BRCA2 (5.5%, RAD51C (2.5% and PALB2 (1.1% genes. The prevalence of deleterious variants did not differ significantly between patients at primary diagnosis and relapse. The prevalence of deleterious variants in BRCA1/2 (and in all 16 risk genes in patients <60 years was 30.2% (33.2% versus 10.6% (18.9% in patients ≥60 years. Family history was positive in 43% of all patients. Patients with a positive family history had a prevalence of deleterious variants

    Full Text Available Polycystic ovarian syndrome (PCOS is a "multispeciality" disorder suspected in patients with irregular menses and clinical signs of hyperandrogenism such as acne, seborrhoea, hirsutism, irregular menses, infertility, and alopecia. Recently, PCOS has been associated with the metabolic syndrome. Patients may develop obesity, insulin resistance, acanthosis nigricans, Type 2 diabetes, dyslipidemias, hypertension, non-alcoholic liver disease, and obstructive sleep apnoea. Good clinical examination with hematological and radiological investigations is required for clinical evaluation. Management is a combined effort involving a dermatologist, endocrinologist, gynecologist, and nutritionist. Morbidity in addition includes a low "self image" and poor quality of life. Long term medications and lifestyle changes are essential for a successful outcome. This article focuses on understanding the normal and abnormal endocrine functions involved in the pathogenesis of PCOS. Proper diagnosis and management of the patient is discussed.

    miR-125b has essential roles in coordinating tumor proliferation, angiogenesis, invasiveness, metastasis and chemotherapy recurrence. In ovarian cancer miR-125b has been shown to be downregulated and acts as a tumor suppressor by targeting proto-oncogene BCL3. PPARγ, a multiple functional transcription factor, has been reported to have anti-tumor effects through inhibition of proliferation and induction of differentiation and apoptosis by targeting the tumor related genes. However, it is unclear whether miR-125b is regulated by PPARγ in ovarian cancer. In this study, we demonstrated that the miR-125b downregulated in ovarian cancer tissues and cell lines. Ligands-activated PPARγ suppressed proliferation of ovarian cancer cells and this PPARγ-induced growth inhibition is mediated by the upregulation of miR-125b. PPARγ promoted the expression of miR-125b by directly binding to the responsive element in miR-125b gene promoter region. Thus, our results suggest that PPARγ can induce growth suppression of ovarian cancer by upregulating miR-125b which inhibition of proto-oncogene BCL3. These findings will extend our understanding of the function of PPARγ in tumorigenesis and miR-125b may be a therapeutic intervention of ovarian cancer. - Highlights: • miR-125b is down-regulated in ovarian cancer tissues and cells. • PPARγ upregulates miR-125b and downregulates its target gene BCL3 expression. • Silence of miR-125b attenuates PPARγ-mediated growth suppression of ovarian cancer cells. • PPARγ promotes the transcription of miR-125b via binding to PPARE in miR-125b gene promoter region.

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

    Obesity is a risk factor for cancer. Epidemiological evidences associate ovarian cancer with obesity. Epithelial ovarian cancer (EOC) is the most common type of ovarian cancer and accounts for a high rate of mortality. The association between ovarian cancer and obesity could be explained by molecular factors secreted by adipose tissue such as leptin. In EOC, leptin increases cell proliferation and inhibits apoptosis. Additionally, adipose tissue synthesizes endogenous estrogens, which increase cell proliferation of epithelial ovarian cells. Also, obesity associated hyperinsulinism could increase ovarian estrogen secretion.

Within thirteen children preoperatively detected mixed cystic-solid lesion, six cases ovarian cysts disappeared and two cases underwent poor blood supply in the following time. Adverse effects for ovarian cyst in infants can be prevented by agressive surgical intervention. Harmful effects of ovarian cyst can be prevented by positive surgical intervention despite the diagnostic difficulties in children with clinical symptoms of this condition.

  4. Premature ovarian failure

    2012-01-01

    Full Text Available Premature ovarian failure (POF is the occurrence of hypergonadotropic hypoestrogenic amenorrhea in women under the age of forty years. It is idiopathic in 74-90% patients. Known cases can be divided into primary and secondary POF. In primary POF genetic aberrations can involve the X chromosome (monosomy, trisomy, translocations, deletions or autosomes. Genetic mechanisms include reduced gene dosage and non-specific chromosome effects impairing meiosis, decreasing the pool of primordial follicles and increasing atresia due to apoptosis or failure of follicle maturation. Autoimmune ovarian damage is caused by alteration of T-cell subsets and T-cell mediated injury, increase of autoantibody producing B-cells, a low number of effector/cytotoxic lymphocyte, which decreases the number and activity of natural killer cells. Bilateral oophorectomy, chemotherapy, radiotherapy and infections cause the secondary POF. Symptoms of POF include irritability, nervousness, loss of libido, depression, lack of concentration, hot flushes, weight gaining, dry skin, vaginal dryness, frequent infections etc. The diagnosis is confirmed by the level of FSH of over 40 IU/L and estradiol below 50 pmol/L in women aged below 40 years. Biochemical and other hormonal analysis (free thyroxin, TSH, prolactin, testosterone, karyotype (<30 years of age, ultrasound of the breasts and pelvis are advisable. Optimal therapy is combined estrogen progestagen therapy given in a sequential rhythm, after excluding absolute contraindications. Testosterone can be added to adnexectomized women and those with a low libido. Sequential estrogen progestagen replacement therapy is the first line therapy for ovulation induction in those looking for pregnancy and after that oocyte donation will be advised. Appropriate estro-progestagen therapy improves the quality of life and prevents complications such as cardiovascular diseases, osteoporosis, stroke etc.

  5. Tamoxifen and ovarian function.

    Martine Berliere

    Full Text Available BACKGROUND: Some studies suggest that the clinical parameter "amenorrhea" is insufficient to define the menopausal status of women treated with chemotherapy or tamoxifen. In this study, we investigated and compared the ovarian function defined either by clinical or biological parameters in pre-menopausal breast cancer patients treated with tamoxifen administered as adjuvant therapy. MATERIALS AND METHODS: Between 1999 and 2003, 138 premenopausal patients consecutively treated for early breast cancer were included. Sixty-eight received tamoxifen in monotherapy as the only adjuvant systemic treatment (Group I and 70 were treated with tamoxifen after adjuvant chemotherapy (Group II. All patients had a confirmed premenopausal status based on clinical parameters and hormonal values at study entry. They were followed prospectively every 3 months for 3 years: menses data, physical examination and blood tests (LH, FSH, 17-beta-estradiol. Vaginal ultrasonography was carried out every 6 months. After 3 years, prospective evaluation was completed and monitoring of ovarian function was performed as usual in our institution (1x/year. All data were retrospectively evaluated in 2011. RESULTS: Three patients were excluded from the study in group I and 2 were excluded in group II. Patients were divided into 4 subgroups according to clinical data, i.e. menses patterns. These patterns were assessed by questionnaires. a: Regular menses (>10 cycles/year b: Oligomenorrhea (5 to 9 cycles/year c: Severe oligomenorrhea (1 to 4 cycles/year d: Complete amenorrhea Estrogen levels did not appear to have any impact on disease-free survival rates after 3 or 8 years. FSH values were also documented and analyzed. They exhibited the same profile as estradiol values. CONCLUSIONS: Amenorrhea is an insufficient parameter to define menopausal status in patients receiving tamoxifen. Low estradiol levels must be coupled with other biological parameters to characterize endocrine status

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

    Parmar, Malvinder S.; Sturge, Cecil

    2003-01-01

    RECURRENT EPISODES OF SPONTANEOUSLY RESOLVING HYPERTHYROIDISM may be caused by release of preformed hormone from the thyroid gland after it has been damaged by inflammation (recurrent silent thyroiditis) or by exogenous administration of thyroid hormone, which might be intentional or surreptitious (thyrotoxicosis factitia). Community-wide outbreaks of “hamburger thyrotoxicosis” resulting from inadvertent consumption of beef contaminated with bovine thyroid gland have been previously reported. Here we describe a single patient who experienced recurrent episodes of this phenomenon over an 11-year period and present an approach to systematically evaluating patients with recurrent hyperthyroidism.

    Takotsubo cardiomyopathy, or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction caused by transient wall-motion abnormalities of the left ventricular apex and mid ventricle in the absence of obstructive coronary artery disease. Recurrent episodes are rare but have been reported, and several cases of takotsubo cardiomyopathy have been described in the presence of hyperthyroidism. We report the case of a 55-year-old woman who had recurrent takotsubo cardiomyopathy, documented by repeat coronary angiography and evaluations of left ventricular function, in the presence of recurrent hyperthyroidism related to Graves disease. After both episodes, the patient's left ventricular function returned to normal when her thyroid function normalized. These findings suggest a possible role of thyroid-hormone excess in the pathophysiology of some patients who have takotsubo cardiomyopathy.

  13. Distinct Patterns of Stromal and Tumor Expression of ROR1 and ROR2 in Histological Subtypes of Epithelial Ovarian Cancer

    2017-06-01

    Full Text Available OBJECTIVE: The ROR1 and ROR2 receptor tyrosine kinases have both been implicated in ovarian cancer progression and have been shown to drive migration and invasion. There is an increasing importance of the role of stroma in ovarian cancer metastasis; however, neither ROR1 nor ROR2 expression in tumor or stromal cells has been analyzed in the same clinical cohort. AIM: To determine ROR1 and ROR2 expression in ovarian cancer and surrounding microenvironment and examine associations with clinicopathological characteristics. METHODS: Immunohistochemistry for ROR1 and ROR2 was used to assess receptor expression in a cohort of epithelial ovarian cancer patients (n = 178. Results were analyzed in relation to clinical and histopathological characteristics and survival. Matched patient sample case studies of normal, primary, and metastatic lesions were used to examine ROR expression in relation to ovarian cancer progression. RESULTS: ROR1 and ROR2 are abnormally expressed in malignant ovarian epithelium and stroma. Higher ROR2 tumor expression was found in early-stage, low-grade endometrioid carcinomas. ROR2 stromal expression was highest in the serous subtype. In matched patient case studies, metastatic samples had higher expression of ROR2 in the stroma, and a recurrent sample had the highest expression of ROR2 in both tumor and stroma. CONCLUSION: ROR1 and ROR2 are expressed in tumor-associated stroma in all histological subtypes of ovarian cancer and hold potential as therapeutic targets which may disrupt tumor and stroma interactions.

    2013-01-20

    The aim of the authors is to present two cases which raise the possibility of an association between polycystic ovarian syndrome/hyperandrogenism and ovarian cyst torsion in peripubertal girls. Androgen excess may cause more frequently ovarian cyst formation in premenarcheal or young adolescents with undiagnosed polycystic ovarian syndrome than in adults. The authors recommend that polycystic ovarian syndrome as well as late onset congenital adrenal hyperplasia should be considered in peripubertal adolescents with ovarian cyst torsion. In case polycystic ovarian syndrome is confirmed, adequate management according to age and pubertal development of the patients should be commenced.

    2009-01-01

    One of the major difficulties in the treatment of epithelial ovarian cancer (EOC) is the high rate of recurrent disease. This is thought to be due to the survival of a population of chemo-resistant cells within the tumor, the ovarian cancer stem cells (OCSCs), that are able to regenerate the tumor following chemotherapy. Therefore, the identification of a compund that can target the OCSCs is one of the main steps in improving overall survival of ovarian cancer patients. The objective of this ...

    Despite remarkable progress in imaging modalities and surgical management, persistence or recurrence of primary hyperparathyroidism (PHPT) still occurs in 2.5-5% of cases of PHPT. The aim of this review is to expose the management of persistent and recurrent hyperparathyroidism. A literature search was performed on MEDLINE using the search terms "recurrent" or "persistent" and "hyperparathyroidism" within the past 10 years. We also searched the reference lists of articles identified by this search strategy and selected those we judged relevant. Before considering reoperation, the surgeon must confirm the diagnosis of PHPT. Then, the patient must be evaluated with new imaging modalities. A single adenoma is found in 68% of cases, multiglandular disease in 28%, and parathyroid carcinoma in 3%. Others causes (<1%) include parathyromatosis and graft recurrence. The surgeon must balance the benefits against the risks of a reoperation (permanent hypocalcemia and recurrent laryngeal nerve palsy). If surgery is necessary, a focused approach can be considered in cases of significant imaging foci, but in the case of multiglandular disease, a bilateral neck exploration could be necessary. Patients with multiple endocrine neoplasia syndromes are at high risk of recurrence and should be managed regarding their hereditary pathology. The cure rate of persistent-PHPT or recurrent-PHPT in expert centers is estimated from 93 to 97%. After confirming the diagnosis of PHPT, patients with persistent-PHPT and recurrent-PHPT should be managed in an expert center with all dedicated competencies.

    In this retrospective study we evaluated the respective correlations and clinical relevance of FOLR1 mRNA expression, FOLR1 promoter specific methylation and global DNA hypomethylation in type I and type II ovarian cancer. Two hundred fifty four ovarian cancers, 13 borderline tumours and 60 samples of healthy fallopian epithelium and normal ovarian epithelium were retrospectively analysed for FOLR1 expression with RT-PCR. FOLR1 DNA promoter methylation and global DNA hypomethylation (measured by means of LINE1 DNA hypomethylation) were evaluated with MethyLight technique. No correlation between FOLR1 mRNA expression and its specific promoter DNA methylation was found neither in type I nor in type II cancers, however, high FOLR1 mRNA expression was found to be correlated with global DNA hypomethylation in type II cancers (p = 0.033). Strong FOLR1 mRNA expression was revealed for Grades 2-3, FIGO stages III-IV, residual disease > 0, and serous histotype. High FOLR1 expression was found to predict increased platinum sensitivity in type I cancers (odds ratio = 3.288; 1.256-10.75; p = 0.020). One-year survival analysis showed in type I cancers an independent better outcome for strong expression of FOLR1 in FIGO stage III and IV. For the entire follow up period no significant independent outcome for FOLR1 expression was revealed. In type I cancers LINE 1 DNA hypomethylation was found to exhibit a worse PFS and OS which were confirmed to be independent in multivariate COX regression model for both PFS (p = 0.026) and OS (p = 0.012). No correlations were found between FOLR1 expression and its specific promoter methylation, however, high FOLR1 mRNA expression was associated with DNA hypomethylation in type II cancers. FOLR1 mRNA expression did not prove to predict clinical outcome in type II cancers, although strong FOLR1 expression generally denotes ovarian cancers with highly aggressive phenotype. In type I cancers, however, strong FOLR1 expression has been found to be a

    2016-12-01

    Full Text Available Ovaries are the female organs that age more quickly than other tissues such as the uterus, the pituitary gland or pancreas. Different from males, an interesting question is why and how the females lose fertility so rapidly. During the aging process, both the number and quality of the oocytes in the ovaries decrease and reach to a point beyond that no more viable offspring may be produced and the associated cyclic endocrinological activities cease, entering the menopause in females at an average age of 50 years. Females who delayed childbearing with or without their willing until their 30 years or 40 years constitute the largest portion of the total infertility population. Ovarian reserve tests (ORTs provide an indirect estimate of a female�s diminishing ovarian reserve or remaining follicular pool. This article briefly reviews recent progresses in relation to ovarian aging and ORTs.

    2016-06-01

    Ovarian cancer is the leading cause of death from gynecologic malignancy in the United States. While the treatment options have improved with conventional cytotoxic chemotherapy and advanced surgical techniques, disease recurrence is common and fatal in nearly all cases. Current evidence suggests that the immune system and its ability to recognize and eliminate microscopic disease is paramount in preventing recurrence. The goal of immunotherapy is to balance the activation of the immune system against cancer while preventing the potential for tremendous toxicity elicited by immune modulation. In this paper we will review the role of immune system in disease pathogenesis and different immunotherapies available for the treatment of ovarian cancer as well as current ongoing studies and potential future directions.

  2. Isolation and characterization of tumor cells from the ascites of ovarian cancer patients: molecular phenotype of chemoresistant ovarian tumors.

    Directory of Open Access Journals (Sweden)

    Ardian Latifi

    Full Text Available Tumor cells in ascites are a major source of disease recurrence in ovarian cancer patients. In an attempt to identify and profile the population of ascites cells obtained from ovarian cancer patients, a novel method was developed to separate adherent (AD and non-adherent (NAD cells in culture. Twenty-five patients were recruited to this study; 11 chemonaive (CN and 14 chemoresistant (CR. AD cells from both CN and CR patients exhibited mesenchymal morphology with an antigen profile of mesenchymal stem cells and fibroblasts. Conversely, NAD cells had an epithelial morphology with enhanced expression of cancer antigen 125 (CA125, epithelial cell adhesion molecule (EpCAM and cytokeratin 7. NAD cells developed infiltrating tumors and ascites within 12-14 weeks after intraperitoneal (i.p. injections into nude mice, whereas AD cells remained non-tumorigenic for up to 20 weeks. Subsequent comparison of selective epithelial, mesenchymal and cancer stem cell (CSC markers between AD and NAD populations of CN and CR patients demonstrated an enhanced trend in mRNA expression of E-cadherin, EpCAM, STAT3 and Oct4 in the NAD population of CR patients. A similar trend of enhanced mRNA expression of CD44, MMP9 and Oct4 was observed in the AD population of CR patients. Hence, using a novel purification method we demonstrate for the first time a distinct separation of ascites cells into epithelial tumorigenic and mesenchymal non-tumorigenic populations. We also demonstrate that cells from the ascites of CR patients are predominantly epithelial and show a trend towards increased mRNA expression of genes associated with CSCs, compared to cells isolated from the ascites of CN patients. As the tumor cells in the ascites of ovarian cancer patients play a dominant role in disease recurrence, a thorough understanding of the biology of the ascites microenvironment from CR and CN patients is essential for effective therapeutic interventions.

    To investigate the prognostic value of intratumoral FDG uptake heterogeneity (IFH) derived from PET/CT in patients with epithelial ovarian cancer (EOC). We retrospectively reviewed patients with pathologically proven epithelial ovarian cancer who underwent preoperative {sup 18}F-FDG PET/CT scans. PET/CT parameters such as maximum and average standardized uptake values (SUV{sub max} and SUV{sub avg}), sum of all metabolic tumour volume (MTV), cumulative total lesion glycolysis (TLG) and IFH were assessed. Regression analyses were used to identify clinicopathological and imaging variables associated with disease-free survival (DFS). Clinicopathological data were reviewed for 61 eligible patients. The median duration of DFS was 13 months (range, 6-26 months), and 18 (29.5 %) patients experienced recurrence. High IFH values were associated with tumour recurrence (P = 0.005, hazard ratio 4.504, 95 % CI 1.572-12.902). The Kaplan-Meier survival graphs showed that DFS significantly differed in groups categorized based on IFH (P = 0.002, log-rank test). Moreover, there were significant differences in DFS (P = 0.009) and IFH (P = 0.040) between patients with and without recurrence. Preoperative IFH measured by {sup 18}F-FDG PET/CT was significantly associated with EOC recurrence. FDG-based heterogeneity could be a useful and potential predicator of EOC recurrence before treatment. (orig.)

    Full Text Available Roles of interleukin-31 (IL-31 in the development and progression of human epithelial ovarian cancer are largely unknown. Studies report that the polymorphisms, rs7977932 C>G and rs4758680 C>A in IL-31, affect the expression level of IL-31. In the present study, we examined 412 patients with epithelial ovarian cancer and 428 healthy individuals to explore whether these polymorphisms are associated with the epithelial ovarian cancer in Chinese women. The genotype of the polymorphisms in each individual was identified. The associations of the polymorphisms with patients’ clinical characteristics and outcomes were evaluated. For rs7977932, the frequency of the CG/GG was significantly decreased in patients with epithelial ovarian cancer. However, the frequency of the rs4758680 CA/AA was significantly increased in those patients. Moreover, the frequency of rs7977932 CG/GG genotype was significantly higher in patients with less advanced FIGO stages. Kaplan-Meier curve showed that patients with CG/GG genotypes of rs7977932 had a decreased risk for recurrence compared to those with CC genotype. Our findings suggested that rs7977932 and rs4758680 of IL-31 may be associated with the development and progression of the epithelial ovarian cancer in the Chinese population. IL-31, therefore, may be a potential therapeutic target for the development of drugs to treat the disease.

    2009-02-01

    The high recurrence and lethality of ovarian cancer at advanced stages is problematic, especially due to the development of numerous micrometastases scattered throughout the abdominal cavity. Fluorescence photodetection (PD) used in combination with surgical resection of malignant tissues has been suggested to improve recovery. Based on promising in vivo results for the detection of bladder cancer, hypericin (Hy), a natural photosensitizer (PS), stands as a good candidate for the photodetection of ovarian cancer. However, due to its hydrophobicity, systemic administration of Hy is problematic. Polymeric nanoparticles (NPs) help to overcome these delivery and stability problems and enable intravenous administration of Hy. In this study, Hy-loaded NPs of polylactic acid were produced with the following properties: (i) mean size of 268 nm, (ii) negative zeta potential, (iii) low residual surfactant and (iv) drug loading of 3.7 % (w/w). The potential of hypericin-loaded nanoparticles for the fluorescence photodetection of ovarian metastases in Fischer 344 rats bearing ovarian tumours was compared to free drug. The selectivity of Hy administered with both formulations was assessed first by fluorescence endoscopy, and then quantified after tissue extraction. The results showed an improved selective accumulation of Hy in ovarian micrometastases when NPs were used.

  8. Prevalence of BRCA1 mutations in familial and sporadic greek ovarian cancer cases.

    Directory of Open Access Journals (Sweden)

    Alexandra V Stavropoulou

    Full Text Available Germline mutations in the BRCA1 and BRCA2 genes contribute to approximately 18% of hereditary ovarian cancers conferring an estimated lifetime risk from 15% to 50%. A variable incidence of mutations has been reported for these genes in ovarian cancer cases from different populations. In Greece, six mutations in BRCA1 account for 63% of all mutations detected in both BRCA1 and BRCA2 genes. This study aimed to determine the prevalence of BRCA1 mutations in a Greek cohort of 106 familial ovarian cancer patients that had strong family history or metachronous breast cancer and 592 sporadic ovarian cancer cases. All 698 patients were screened for the six recurrent Greek mutations (including founder mutations c.5266dupC, p.G1738R and the three large deletions of exon 20, exons 23-24 and exon 24. In familial cases, the BRCA1 gene was consequently screened for exons 5, 11, 12, 20, 21, 22, 23, 24. A deleterious BRCA1 mutation was found in 43/106 (40.6% of familial cancer cases and in 27/592 (4.6% of sporadic cases. The variant of unknown clinical significance p.V1833M was identified in 9/698 patients (1.3%. The majority of BRCA1 carriers (71.2% presented a high-grade serous phenotype. Identifying a mutation in the BRCA1 gene among breast and/or ovarian cancer families is important, as it enables carriers to take preventive measures. All ovarian cancer patients with a serous phenotype should be considered for genetic testing. Further studies are warranted to determine the prevalence of mutations in the rest of the BRCA1 gene, in the BRCA2 gene, and other novel predisposing genes for breast and ovarian cancer.

    Computed tomographic scans of 34 patients with ovarian metastases were reviewed to assess the radiographic appearances and to correlate these with the primary neoplasms. Primary neoplasms were located in the colon (20 patients), breast (six), stomach (five), small bowel (one), bladder (one), and Wilms tumor of the kidney (one). The radiographic appearance of the metastatic lesions could be described as predominantly cystic (14 lesions), mixed (12 lesions), or solid (seven lesions). The cystic and mixed lesions tended to be larger in overall diameter than the solid. The metastases from gastric carcinoma appeared solid in four of five cases. The metastases from the other neoplasms had variable appearances simulating primary ovarian carcinoma

    Ovarian vein thrombosis is a rare postpartum complication (0.1%). It can be fatal, since it can lead to sepsis, pulmonary thromboembolisms and inferior vena cava or renal vein thrombosis. Computed tomography and magnetic resonance imaging are the techniques of choice for its diagnosis, while the value of ultrasound is limited due to its low sensitivity and specificity. We report the case of a woman who, during puerperium, developed thrombosis of right ovarian vein that presented clinical, ultrasonographic and computed tomographic features of appendicitis. We describe the radiological sings and stress the fact that this diagnosis should be suspected in puerperal women. (Author) 9 refs

    Bates, G Wright; Propst, Anthony M

    2012-12-01

    Polycystic ovarian syndrome (PCOS) is a disorder of androgen excess and ovarian dysfunction. Hirsutism and elevated free testosterone levels are the most consistent signs of the androgen excess. Irregular, infrequent, or absent menses and infertility are symptoms of ovulatory dysfunction. Obesity is also a feature of this syndrome and contributes to associated metabolic abnormalities. Lifestyle modification should be the first treatment and is effective in reducing the signs and symptoms. The ovulatory infertility associated with PCOS can be overcome in most cases with oral (clomiphene citrate or letrozole) or injectable (gonadotropins) agents. Surgical intervention is reserved for cases resistant to medical management. Copyright © 2012 Elsevier Inc. All rights reserved.

  14. Radiation therapy for epithelial ovarian cancer

    International Nuclear Information System (INIS)

    Dembo, A.J.

    1987-01-01

    Several principles governing the cure of patients with ovarian cancer by radiotherapy were established during the last decade. The author reviews some of the studies at The Princess Margaret Hospital (PMH), which led to the establishment of the following principles: The entire peritoneal cavity should be encompassed by the treatment field, because once the disease has spread beyond the ovary, the entire peritoneal cavity is at risk for recurrent cancer. The moving-strip and open-field techniques are equally effective in tumor control. Late complications can be kept to a minimum (<5% bowel surgery, <1% radiation hepatitis, < 1% treatment mortality), but their frequency increases with increasing total radiation dosage, increasing fraction size, and possibly the extent of the previous surgical procedures (Dembo 1985a). Optimal selection of patients for radiotherapy compared with other forms of treatment is based on grouping of patients according to prognostic factors, including presenting stage of disease, amount and site of residual tumor, and histophatologic features. The potential exists for abdominopelvic radiation to be applied curatively as consolidation or as salvage therapy for patients whose disease has not been completely eradicated by chemotherapy;however, further study is needed to clarify the magnitude of this benefit, the situations in which radiotherapy is indicated, and factors that determine the toxicity of the combined-modality treatment

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

    The objective of research is to investigate radioimmunoimaging (RII) on ovarian tumor by labelling anti-ovarian cancer monoclonal antibody (OC125) with 99m Tc. the nude mice models were produced by injection ovarian serous cyst adenocarcinoma cell HO8910. Experimental group was injected with 99m Tc-OC125 as tracer and control groups were injected normal mice IgG labelled with 99m Tc and anti-HO8910 antibody labelled with 99m Tc. RII using 99m Tc-OC125 McAb was also performed on 4 nude mice model of glioma (control group). Imaging positive rate, negative rate and tumor/non-tumor ratio were calculated. Results show positive rate of imaging of tumor was 100%. The most distinct pictures were gained between 4 to 6 h after injection of tracer. T/NT ratios of experimental group were higher than that of control groups (P 99m Tc on the nude mice models was sensitive and specific. 16 ovarian neoplasm patients were received RII 6 h after intravenous injected OC125 McAb labelled with 99m Tc. Four patients of malignant tumor repeated RII after operation and chemotherapy. The result of RII was accorded perfectly with operation. RII also can find micro recurrence focus of post-operation. The sensitivity and specificity was more excellent than the radioimmunoassay of CA125. RII is useful for defining character of ovarian tumor, especially for detecting early recurrence focus of post-operation patients

    Polycystic ovarian disease (PCOD) was first described as a single disease by Stein and Leventhal in 1935, but now has been separated into several distinct entities, comprising a symptom complex. The most frequent presenting symptoms associated with PCOD are obesity, hirsutism, amenorrhea or anovulation, dysfunctional uterine bleeding, irregular menses, and infertility. The common finding of hirsutism in PCOD patients is a reflection of the hyperandrogenism resulting from elevation of all the androgens, including testosterone, androstenediol, dehydroepiandrostrone sulfate (DHEA-S), and androstenedione. Some patients with all the clinical features of PCOD can be shown, through appropriate testing, to have an attenuated form of classic congenital adrenal hyperplasia (CAH). Serum follicle stimulating hormone (FSH) levels are usually low or in the normal range, and serum luteinizing hormone (LH) levels are usually elevated in patients with PCOD, resulting in an altered LH/FSH ratio. Treatment for PCOD must be based on the needs and desires of the individual patient, and on the pathophysiology of the patient's particular abnormalities. When pregnancy is desired, ovulation induction with clomiphene is indicated. Clomiphene is a weak estrogen that induces a transient rise in serum LH and FSH, followed by a gonadotropic pattern similar to normal cycles. A 72% ovulation rate and a 41.8% conception rate have been reported after treatment with clomiphene. In patients who do not respond to clomiphene, or clomiphene with added human chorionic gonadotropin (hCG), human menopausal gonadotropin (hMG) can be used to induce ovulation, but the patient should be closely monitored for multiple ovulation, multiple pregnancy, or hyperstimulation syndrome. For patients not interested in conception, regular menstrual cyclicity can be restored and hyperandrogenism reduced with oral contraceptives (OCs).

    Ovarian and colonic CEA were compared immunologically by means of antisera prepared against each of them. CEAs of both origins were found identical by immunodiffusion methods. In radioimmunological experiments, slight differences were observed between some but not all ovarian CEAs and colonic CEAs and also between different preparations of colonic CEA: no organ specificity of ovarian CEA could be demonstrated. Finally, CEA level was measured in 41 sera of patients with ovarian carcinoma by two radioimmunoassays, one using colonic CEA as tracer and standard and anti-colonic CEA serum, the other using ovarian CEA and anti-ovarian CEA serum: the values given by the two assays were highly correlated (rsub(s) = 0.8107), meaning that an organ specific assay for ovarian CEA is not needed.

    Ovarian cancer represents the most lethal gynecological cancer. Although cytoreductive chemotherapy and surgery lead to complete macroscopic tumor removal, most of the patients in advanced stages suffer from recurrent disease and subsequently die. This may be explained by the activity of cancer stem cells (CSC), which are a subpopulation of cells with an elevated chemoresistance and an increased capacity for self-renewal and metastatic spread. Specifically targeting these cells by adoptive immunotherapy represents a promising strategy to reduce the risk for recurrent disease. This study selected the widely accepted CSC marker CD133 as a target for a chimeric antigen receptor (CAR)-based immunotherapeutic approach to treat ovarian cancer. A lentiviral vector was generated encoding a third-generation anti-CD133-CAR, and clinically used NK92 cells were transduced. These engineered natural killer (NK) cells showed specific killing against CD133-positive ovarian cancer cell lines and primary ovarian cancer cells cultured from sequential ascites harvests. Additionally, specific activation of these engineered NK cells was demonstrated via interferon-gamma secretion assays. To improve clinical efficacy of ovarian cancer treatment, the effect of the chemotherapeutic agent cisplatin was evaluated together with CAR-transduced NK cell treatment. It was demonstrated that NK cells remain cytotoxic and active under cisplatin treatment and, importantly, that sequential treatment with cisplatin followed by CAR-NK cells led to the strongest killing effect. The specific eradication of ovarian CSCs by anti-CD133-CAR expressing NK92 cells represents a promising strategy and, when confirmed in vivo, shall be the basis of future clinical studies with the aim to prevent recurrent disease.

    To gain a better understanding of the role of somatic mutations in olaparib response, next-generation sequencing (NGS) of BRCA1 and BRCA2 was performed as part of a planned retrospective analysis of tumors from a randomized, double-blind, Phase II trial (Study 19; D0810C00019; NCT00753545) in 265 patients with platinum-sensitive high-grade serous ovarian cancer. BRCA1/2 loss-of-function mutations were found in 55% (114/209) of tumors, were mutually exclusive, and demonstrated high concordance with Sanger-sequenced germline mutations in matched blood samples, confirming the accuracy (97%) of tumor BRCA1/2 NGS testing. Additionally, NGS identified somatic mutations absent from germline testing in 10% (20/209) of the patients. Somatic mutations had >80% biallelic inactivation frequency and were predominantly clonal, suggesting that BRCA1/2 loss occurs early in the development of these cancers. Clinical outcomes between placebo- and olaparib-treated patients with somatic BRCA1/2 mutations were similar to those with germline BRCA1/2 mutations, indicating that patients with somatic BRCA1/2 mutations benefit from treatment with olaparib.

  1. Lovastatin induces apoptosis of ovarian cancer cells and synergizes with doxorubicin: potential therapeutic relevance

    Ovarian carcinoma is a rarely curable disease, for which new treatment options are required. As agents that block HMG-CoA reductase and the mevalonate pathway, the statin family of drugs are used in the treatment of hypercholesterolemia and have been shown to trigger apoptosis in a tumor-specific manner. Recent clinical trials show that the addition of statins to traditional chemotherapeutic strategies can increase efficacy of targeting statin-sensitive tumors. Our goal was to assess statin-induced apoptosis of ovarian cancer cells, either alone or in combination with chemotherapeutics, and then determine these mechanisms of action. The effect of lovastatin on ovarian cancer cell lines was evaluated alone and in combination with cisplatin and doxorubicin using several assays (MTT, TUNEL, fixed PI, PARP cleavage) and synergy determined by evaluating the combination index. The mechanisms of action were evaluated using functional, molecular, and pharmacologic approaches. We demonstrate that lovastatin induces apoptosis of ovarian cancer cells in a p53-independent manner and synergizes with doxorubicin, a chemotherapeutic agent used to treat recurrent cases of ovarian cancer. Lovastatin drives ovarian tumor cell death by two mechanisms: first, by blocking HMG-CoA reductase activity, and second, by sensitizing multi-drug resistant cells to doxorubicin by a novel mevalonate-independent mechanism. This inhibition of drug transport, likely through inhibition of P-glycoprotein, potentiates both DNA damage and tumor cell apoptosis. The results of this research provide pre-clinical data to warrant further evaluation of statins as potential anti-cancer agents to treat ovarian carcinoma. Many statins are inexpensive, off-patent generic drugs that are immediately available for use as anti-cancer agents. We provide evidence that lovastatin triggers apoptosis of ovarian cancer cells as a single agent by a mevalonate-dependent mechanism. Moreover, we also show lovastatin synergizes

    Drug resistance is a cause of ovarian cancer recurrence and low overall survival rates. There is a need for more effective treatment approaches because the development of new drug is expensive and time consuming. Alternatively, the concept of ‘drug repurposing’ is promising. We focused on Bithionol (BT), a clinically approved anti-parasitic drug as an anti-ovarian cancer drug. BT has previously been shown to inhibit solid tumor growth in several preclinical cancer models. A better understanding of the anti-tumor effects and mechanism(s) of action of BT in ovarian cancer cells is essential for further exploring its therapeutic potential against ovarian cancer. The cytotoxic effects of BT against a panel of ovarian cancer cell lines were determined by Presto Blue cell viability assay. Markers of apoptosis such as caspases 3/7, cPARP induction, nuclear condensation and mitochondrial transmembrane depolarization were assessed using microscopic, FACS and immunoblotting methods. Mechanism(s) of action of BT such as cell cycle arrest, reactive oxygen species (ROS) generation, autotaxin (ATX) inhibition and effects on MAPK and NF-kB signalling were determined by FACS analysis, immunoblotting and colorimetric methods. BT caused dose dependent cytotoxicity against all ovarian cancer cell lines tested with IC 50 values ranging from 19 μM – 60 μM. Cisplatin-resistant variants of A2780 and IGROV-1 have shown almost similar IC 50 values compared to their sensitive counterparts. Apoptotic cell death was shown by expression of caspases 3/7, cPARP, loss of mitochondrial potential, nuclear condensation, and up-regulation of p38 and reduced expression of pAkt, pNF-κB, pIκBα, XIAP, bcl-2 and bcl-xl. BT treatment resulted in cell cycle arrest at G1/M phase and increased ROS generation. Treatment with ascorbic acid resulted in partial restoration of cell viability. In addition, dose and time dependent inhibition of ATX was observed. BT exhibits cytotoxic effects on various

    Full Text Available The objective of this study was to compare the diagnostic accuracy of transvaginal ultrasound (TVS, as a less invasive technique instead of hormonal assay to evaluate the ovarian reserve. This study included fifty-five females with breast cancer and we compared the ovarian reserve for these patients by hormonal assay through measuring the serum AntiMullerian Hormone (AMH level and follicular stimulating hormone (FSH level before and after chemotherapy, and by transvaginal ultrasound through the ovarian volume (OV calculation and counting the Antral follicles (AFC before and after chemotherapy treatment. There was decline in the AntiMullerian Hormone level after chemotherapy by 27 ± 11.19% and decrease in the Antral follicle counts by 21 ± 13.43%. In conclusion there was strong relation between AMH level and AFC which makes the use of transvaginal ultrasound is a reliable alternative method to the hormonal assay to detect the ovarian reserve.

Finally, the concept of a 'chemical' cytoreduction preceding and facilitating a subsequent 'surgical' effort has been recently introduced also in the treatment of recurrent disease. The EORTC has recently initiated a prospective randomized study (LOROCSON - Late Onset Recurrent Ovarian Cancer: Surgery or Not) to validate the importance of such an approach to be balanced with medical treatment alone not only in terms of survival but also as far as quality of life is concerned.

    Drug resistance to conventional anticancer therapies is almost inevitable in patients with advanced ovarian cancer (AOC), limiting their available treatment options. Novel phase I trial therapies within a dedicated drug development unit may represent a viable alternative; however, there is currently little evidence for patient outcomes in such patients. To address this, we undertook a retrospective review of patients with AOC allocated to phase I trials in the Drug Development Unit at Royal Marsden Hospital (RMH) between June 1998 and October 2010. A total of 200 AOC patients with progressive disease were allocated to ≥1 trial each, with a total of 281 allocations. Of these, 135 (68%) patients commenced ≥1 trial (mean 1.4 [1-8]), totaling 216 allocated trials; 65 (32%) patients did not start due to deterioration resulting from rapidly progressive disease (63 patients) or patient choice (2 patients). Response Evaluation Criteria in Solid Tumours (RECIST) complete/partial responses (CR/PR) were observed in 43 (20%) of those starting trials, including those on poly(ADP-ribose) polymerase (PARP) inhibitors (18/79 [23%]), antiangiogenics (9/65 [14%]) and chemotherapy combinations (14/43 [33%]). Factors associated with CR/PR included: fewer prior treatments, platinum-sensitive disease, CR/PR with prior therapy, (the United States-based) Eastern Cooperative Oncology Group (ECOG) performance status score, fewer metastatic sites, higher albumin and haemoglobin levels, lower white cell counts and baseline CA125 levels, germline BRCA1/2 mutations and better RMH Prognostic Score. Mean survival was 32° months for patients who achieved CR/PR. Treatments were generally well tolerated. Most patients with AOC (134/200 [67%]) received ≥1 subsequent line of therapy after phase I trials. Our data suggest that phase I trial referrals should be considered earlier in the AOC treatment pathway and before the onset of rapid disease progression particularly with the emergence of

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23–37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

    Objective: An elevated total plasma homocysteine level has been suggested as a possible risk factor in women suffering from recurrent pregnancy loss. The current study was undertaken to assess the association between homocysteine, folate, cobalamin (vitamin B12) and the risk of recurrent pregnancy loss. Design: Case . control study Materials and Methods: The study included 57 non-pregnant Egyptian women. They were classified according to their obstetric history into 2 groups: 32 cases with at least two consecutive miscarriages (Study group), and 25 cases with normal obstetric history (Control group). All cases were tested for plasma total homocysteine, serum folate and cobalamin (vitamin B12). Results: The fasting total homocysteine was significantly higher in the study group as compared to the control group. While the median concentrations for the vitamins studied were significantly lower in women of the study group as compared to the controls. Elevated homocysteine and reduced vitamin B12 can be considered risk factors for recurrent miscarriage with odds ratio (OR) and 95% confidence intervals (95% CI) of 1.839 (1.286, 2.63) and 1.993 (1.346, 2.951) respectively in the group of recurrent miscarriages. The OR (95% CI) in the study population for low serum folate concentrations was 1.23 (0.776, 2.256). Conclusion: Elevated homocysteine and reduced serum vitamin B12 are risk factors for recurrent miscarriage. Low serum folate did not seem a risk factor for recurrent miscarriage. Testing for homocysteine levels in women suffering from unexplained recurrent miscarriage and pre-conceptional supplementation with vitamin B12 might be beneficial to improve pregnancy outcome

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

    To assess recurrence and pregnancy rates in women with ovarian endometrioma treated via ablation using plasma energy. Retrospective non-comparative pilot study including 55 patients treated during 28 months, with prospective recording of data (Canadian Task Force classification II-2). Tertiary referral center. Fifty-five consecutive women with pelvic endometriosis in whom ovarian endometriomas were managed solely via ablation using plasma energy. The minimum follow-up was 1 year. Endometrioma ablation using plasma energy. Information was obtained from the database of the North-West Inter Regional Female Cohort for Patients with Endometriosis, based on self-questionnaires completed before surgery, surgical and histologic data, and systematic recording of recurrences, pregnancy, and symptoms. Recurrences were assessed using pelvic ultrasound examination. Mean (SD) follow-up was 20.6 (7.2) months (range, 12-39 months). In 75% of patients, deep infiltrating endometriosis was treated, and 40% had colorectal involvement. Preoperative infertility was recorded in 42% of patients. The rate of postoperative recurrence was 10.9% for the entire series. Of 33 women who wished to conceive, 67% became pregnant, spontaneously in 59%. Time from surgery to the first pregnancy was 7.6 (4.3) months. After discontinuation of postoperative hormone therapy, the probability of not conceiving at 12 months was 0.36 (95% confidence interval, 0.19-0.53), and at 24 months was 0.27 (95% confidence interval, 0.12-0.44). Recurrence and pregnancy rates are encouraging in that they seem comparable to the best reported results after endometrioma cystectomy. Plasma energy may have an important role in the management of ovarian endometrioma in women seeking to conceive. Patients most in need of surgical procedures that can spare ovarian parenchyma, such as those with bilateral endometriomas or a history of ovarian surgery, may particularly benefit from ablation using plasma energy.

    tumors among women with a benign ovarian tumor. METHODS: This nationwide cohort study included all Danish women diagnosed with a benign ovarian tumor (n=139,466) during 1978-2012. The cohort was linked to the Danish Pathology Data Bank and standardized incidence ratios (SIR) with 95% confidence intervals...... (CI) were calculated. RESULTS: Women with benign ovarian tumors had increased risks for subsequent borderline ovarian tumors (SIR 1.62, 95% CI 1.43-1.82), and this applied to both serous (SIR 1.69, 95% CI 1.39-2.03) and mucinous (SIR 1.75, 95% CI 1.45-2.10) histotypes of borderline ovarian tumors.......

    Bell's palsy in known as the most common cause of facial paralysis, determined by the acute onset of lower motor neuron weakness of the facial nerve with no detectable cause. With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of the untreated cases. Clinical trials performed for Bell's palsy have reported some recurrences, ipsilateral or contralateral to the side affected in the primary episode of facial palsy. Only few data are found in the literature. Melkersson-Rosenthal is a rare neuromucocutaneous syndrome characterized by recurrent facial paralysis, fissured tongue (lingua plicata), orofacial edema. We attempted to analyze some clinical and epidemiologic aspects of recurrent idiopathic palsy, and to develop relevant correlations between the existing data in literature and those obtained in this study. This is a retrospective study carried out on a 10-years period for adults and a five-year period for children. A number of 185 patients aged between 4 and 70 years old were analyzed. 136 of them were adults and 49 were children. 22 of 185 patients with Bell's palsy (12%) had a recurrent partial or complete facial paralysis with one to six episodes of palsy. From this group of 22 cases, 5 patients were diagnosed with Melkersson-Rosenthal syndrome. The patients' age was between 4 and 70 years old, with a medium age of 27,6 years. In the group studied, fifteen patients, meaning 68%, were women and seven were men. The majority of patients in our group with more than two facial palsy episodes had at least one episode on the contralateral side. Our study found a significant incidence of recurrences of idiopathic facial palsy. Recurrent idiopathic facial palsy and Melkersson-Rosenthal syndrome is diagnosed more often in young females. Recurrence is more likely to occur in the first two years from the onset, which leads to the conclusion that we should have a follow up of patients

    Full Text Available Abstract Due to the low survival rates from invasive ovarian cancer, new effective treatment modalities are urgently needed. Compelling evidence indicates that the immune response against ovarian cancer may play an important role in controlling this disease. We herein summarize multiple immune-based strategies that have been proposed and tested for potential therapeutic benefit against advanced stage ovarian cancer. We will examine the evidence for the premise that an effective therapeutic vaccine against ovarian cancer is useful not only for inducing remission of the disease but also for preventing disease relapse. We will also highlight the questions and challenges in the development of ovarian cancer vaccines, and critically discuss the limitations of some of the existing immunotherapeutic strategies. Finally, we will summarize our own experience on the use of patient-specific tumor-derived heat shock protein-peptide complex for the treatment of advanced ovarian cancer.

    The objective of this study was to explore the feasibility and methods of screening the residual normal ovarian tissue adjacent to orthotopic ovarian carcinomas in nude mice. Human epithelial ovarian cancer cells (OVCAR3) were subcutaneously implanted for a tumor source and ovarian orthotopic transplantation. The cancer tissue, proximal paraneoplastic tissue, middle paraneoplastic tissue, remote paraneoplastic tissue, and normal ovarian tissue were removed. CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was detected by reverse transcription polymerase chain reaction. We obtained 35 paraneoplastic residual ovarian tissues with normal biopsies from 40 cases of an orthotopic epithelial ovarian carcinoma model (87.5%). CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was lower in proximal paraneoplastic tissue than in cancer tissue (P tissue (P tissue as well as among residual normal ovarian tissues with different severity (P > 0.05). In ovarian tissues of 20 normal nude mice, the expression of CK- 7, CA125, p53, survivin, MMP-2, and TIMP-2 was negative. Overall, the expression levels of CK-7, CA125, p53, survivin, MMP-2, TIMP-2, and other molecular markers showed a decreasing trend in the non-cancer tissue direction. The expression levels can be used as standards to screen residual normal ovarian tissue. We can obtain relatively safe normal ovarian tissues adjacent to epithelial ovarian cancer.

    Full Text Available Recurrent parotitis is an uncommon condition in children. Its etiological factors have not been proved till date although causes due to genetic inheritance, local autoimmune manifestation, allergy, viral infection and immunodeficiency have been suggested. The exact management of this disorder is not yet standardized, but a conservative approach is preferred and all affected children should be screened for Sjogren′s syndrome and immune deficiency including human immunodeficiency virus. We report a 12 years female child who presented with 12 episodes of non-painful recurrent swellings of the bilateral parotid gland in the past 3 years.

    2013-01-01

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

    An altered metabolism during ovarian cancer progression allows for increased macromolecular synthesis and unrestrained growth. However, the metabolic phenotype of cancer stem or tumor-initiating cells, small tumor cell populations that are able to recapitulate the original tumor, has not been well characterized. In the present study, we compared the metabolic phenotype of the stem cell enriched cell variant, MOSE-L{sub FFLv} (TIC), derived from mouse ovarian surface epithelial (MOSE) cells, to their parental (MOSE-L) and benign precursor (MOSE-E) cells. TICs exhibit a decrease in glucose and fatty acid oxidation with a concomitant increase in lactate secretion. In contrast to MOSE-L cells, TICs can increase their rate of glycolysis to overcome the inhibition of ATP synthase by oligomycin and can increase their oxygen consumption rate to maintain proton motive force when uncoupled, similar to the benign MOSE-E cells. TICs have an increased survival rate under limiting conditions as well as an increased survival rate when treated with AICAR, but exhibit a higher sensitivity to metformin than MOSE-E and MOSE-L cells. Together, our data show that TICs have a distinct metabolic profile that may render them flexible to adapt to the specific conditions of their microenvironment. By better understanding their metabolic phenotype and external environmental conditions that support their survival, treatment interventions can be designed to extend current therapy regimens to eradicate TICs. - Highlights: • Ovarian cancer TICs exhibit a decreased glucose and fatty acid oxidation. • TICs are more glycolytic and have highly active mitochondria. • TICs are more resistant to AICAR but not metformin. • A flexible metabolism allows TICs to adapt to their microenvironment. • This flexibility requires development of specific drugs targeting TIC-specific changes to prevent recurrent TIC outgrowth.

    Cytotoxic chemotherapy is an effective and traditional treatment of ovarian cancer. However, chemotherapy-induced apoptosis may also trigger and ultimately accelerate the repopulation of the small number of adjacent surviving cells. This study mainly focused on the tumour cell repopulation caused by chemotherapy in ovarian cancer and the adjunctive/synergistic effect of Berberine on the prevention of tumour repopulation. The transwell system was used to mimic the co-culture of surviving ovarian cancer cells in the microenvironment of cytotoxic chemotherapy-treated dying cells. Tumour cell proliferation was observed by crystal violet staining. AA and PGE 2 levels were measured by ELISA, and changes of protein expression were analysed by Western blot. Chemotherapy drug VP16 treatment triggered AA pathway, leading to the elevated PGE 2 level, and ultimately enhanced the repopulation of ovarian cancer cells. Berberine can block the caspase 3-iPLA 2 -AA-COX-2-PGE 2 pathway by inhibiting the expression of iPLA 2 and COX-2. Berberine can also reverse the increased phosphorylation of FAK caused by abnormal PGE 2 level and thus reverse the repopulation of ovarian cancer cells after VP16 treatment. Our observation suggested that Berberine could inhibit the chemotherapy-induced repopulation of ovarian cancer cells by suppressing the AA pathway and phosphorylation of FAK. And these findings implicated a novel combined use of Berberine and chemotherapeutics, which might prevent ovarian cancer recurrence by abrogating early tumour repopulation. © 2017 John Wiley & Sons Ltd.

    Ovarian dysgerminoma cases very rarely present with acute abdomen due to adnexal torsion and the successful laparoscopic management of such a case has not been reported previously. A 17-year-old sexually inactive high school girl presenting with acute abdomen was referred to our emergency department. Transabdominal ultrasonography showed the presence of homogeneous tumor in the lower abdomen. Emergency laparoscopic surgery was performed and left ovarian tumor with adnexal torsion was identified. Left salpingo-oophorectomy was performed carefully to avoid damaging the tumor capsule and the excised tissue was removed after retrieval in an endobag. The histopathological diagnosis was pure ovarian dysgerminoma. The postoperative course was uneventful. Laparoscopic management with careful postoperative follow-up to monitor recurrence could be a treatment option in a young girl with dysgerminoma, if the disease condition is detected in the early stage.

  15. Significance of the tumor markers CA 125 and CA 15-3 in postoperative diagnosis of ovarian and breast cancer

    Johannsen, B.; Bartel, U.; Elling, D.

    1989-01-01

    In 271 patients with ovarian carcinoma, benign ovarian tumors, breast cancer, and two control groups, serum levels of CA 125, CA 15-3, CEA and, partly, CA 19-9 were determined immunoradiometrically. According to the results of the determination of CA 125 in the follow-up of ovarian carcinoma, CA 125 represents a useful marker for early detection of recurrences, especially in cases of diffuse carcinoma dissemination. In incomplete tumor debulking, postoperative CA 125 serum levels did not prove to be helpful except that a positive level renders invasive diagnostic investigation no longer necessary. Postoperative follow-up in breast cancer early reveals distant metastases, with very high levels in patients with bone metastases. By simultaneous measurement of CA 15-3 and CEA the sensitivity could be increased from 86% (CA 15-3 only) to 93%. (author)

    2006-05-01

    Full Text Available Massive ovarian edema (MOE is a rare entity characterized by an accumulation of stromal edema fluid and occurs primarily in young women. The etiology is not clear, but is suspected to be the result of partial torsion of the ovary. After the establishment of a correct diagnosis, organ-sparing surgical treatment is the standard treatment. With the assistance of laparoscopy, we diagnosed and managed MOE in a 26-year-old woman who had a 4-year history of primary infertility and intermittent lower abdominal pain that had lasted for more than 6 months. With de-torsion, wedge resection, and plication of the ovary, the patient was successfully relieved of the abdominal pain and experienced no recurrence in the follow-up period. A later spontaneous pregnancy demonstrated the practicality of this conservative treatment.

    Hydatid disease is a parasitic infection that most commonly affects the liver and lungs, although the disease can arise in any part of the body. Cysts may mimic many benign and malignant conditions. The diagnosis cannot be confirmed preoperatively in all cases. A 44-yr-old menopausal woman was admitted to the department of gynecology with complaints of abdominal distention. A fixed abdominopelvic mass was identified. Radiology revealed a 20-cm mass with branched septations and solid components. CA-125 level was 55 kU/L, and Risk of Malignancy Index-2 score was 880. These findings suggested the presence of an ovarian neoplasm, and laparotomy was performed. Cystic masses measuring 22 cm and 4 cm, originating from the omentum majus and left ovary, respectively, were found during surgery. Frozen-section analysis revealed hydatid disease. Infracolic omentectomy and total abdominal hysterectomy with bilateral salpingo-oopherectomy were performed. Results of a serum Echinococcus hemagglutination test performed immediately after surgery were negative. The patient was prescribed albendazole for 6 mo and discharged on the third postoperative day with no complaints. The incidence of hydatid disease in the female reproductive system is very rare; however, clinicians must be aware of this disease and take necessary precautions while operating because any spillage may lead to anaphylactic shock and increased risk of recurrence.

    House, Carrie Danielle; Hernandez, Lidia; Annunziata, Christina Messineo

    2014-01-01

    Serous epithelial ovarian cancer (SEOC) is the most lethal gynecological cancer in the United States with disease recurrence being the major cause of morbidity and mortality. Despite recent advances in our understanding of the molecular mechanisms responsible for the development of SEOC, the survival rate for women with this disease has remained relatively unchanged in the last two decades. Preclinical mouse models of ovarian cancer, including xenograft, syngeneic, and genetically engineered mice, have been developed to provide a mechanism for studying the development and progression of SEOC. Such models strive to increase our understanding of the etiology and dissemination of ovarian cancer in order to overcome barriers to early detection and resistance to standard chemotherapy. Although there is not a single model that is most suitable for studying ovarian cancer, improvements have led to current models that more closely mimic human disease in their genotype and phenotype. Other advances in the field, such as live animal imaging techniques, allow effective monitoring of the microenvironment and therapeutic efficacy. New and improved preclinical mouse models, combined with technological advances to study such models, will undoubtedly render success of future human clinical trials for patients with SEOC.

    2015-01-01

    We investigated whether there might be excess ovarian cancer mortality among women residing near Spanish industries, according to different categories of industrial groups and toxic substances. An ecologic study was designed to examine ovarian cancer mortality at a municipal level (period 1997–2006). Population exposure to pollution was estimated by means of distance from town to facility. Using Poisson regression models, we assessed the relative risk of dying from ovarian cancer in zones around installations, and analyzed the effect of industrial groups and pollutant substances. Excess ovarian cancer mortality was detected in the vicinity of all sectors combined, and, principally, near refineries, fertilizers plants, glass production, paper production, food/beverage sector, waste treatment plants, pharmaceutical industry and ceramic. Insofar as substances were concerned, statistically significant associations were observed for installations releasing metals and polycyclic aromatic chemicals. These results support that residing near industries could be a risk factor for ovarian cancer mortality. - Highlights: • We studied excess mortality due to ovarian cancer near Spanish industries. • Integrated nested Laplace approximations were used as a Bayesian inference tool. • We found excess ovarian cancer mortality near all industrial groups as a whole. • Risk also was found in towns near industries releasing carcinogens and metals. • Risk was associated with plants releasing polycyclic aromatic chemicals and POPs. - Our results support that residing in the vicinity of pollutant industries could be a risk factor for ovarian cancer mortality

    We investigated whether there might be excess ovarian cancer mortality among women residing near Spanish industries, according to different categories of industrial groups and toxic substances. An ecologic study was designed to examine ovarian cancer mortality at a municipal level (period 1997-2006). Population exposure to pollution was estimated by means of distance from town to facility. Using Poisson regression models, we assessed the relative risk of dying from ovarian cancer in zones around installations, and analyzed the effect of industrial groups and pollutant substances. Excess ovarian cancer mortality was detected in the vicinity of all sectors combined, and, principally, near refineries, fertilizers plants, glass production, paper production, food/beverage sector, waste treatment plants, pharmaceutical industry and ceramic. Insofar as substances were concerned, statistically significant associations were observed for installations releasing metals and polycyclic aromatic chemicals. These results support that residing near industries could be a risk factor for ovarian cancer mortality. Copyright © 2015 Elsevier Ltd. All rights reserved.

  15. Etiology and Pathogenesis of Epithelial Ovarian Cancer

    Directory of Open Access Journals (Sweden)

    Samuel C. Mok

    2007-01-01

    Full Text Available Ovarian cancer is complex disease composed of different histological grades and types. However, the underlying molecular mechanisms involved in the development of different phenotypes remain largely unknown. Epidemiological studies identified multiple exogenous and endogenous risk factors for ovarian cancer development. Among them, an inflammatory stromal microenvironment seems to play a critical role in the initiation of the disease. The interaction between such a microenvironment, genetic polymorphisms, and different epithelial components such as endosalpingiosis, endometriosis, and ovarian inclusion cyst in the ovarian cortex may induce different genetic changes identified in the epithelial component of different histological types of ovarian tumors. Genetic studies on different histological grades and types provide insight into the pathogenetic pathways for the development of different disease phenotypes. However, the link between all these genetic changes and the etiological factors remains to be established.

    Massive ovarian edema is a benign clinical entity, the imaging findings of which can mimic an adnexal mass or ovarian torsion. In the setting of acute abdominal pain, identifying massive ovarian edema is a key in avoiding potential fertility-threatening surgery in young women. In addition, it is important to consider other contributing pathology when ovarian edema is secondary to another process. We present a case of a young woman presenting with subacute abdominal pain, whose initial workup revealed marked enlarged right ovary. Further imaging, diagnostic tests, and eventually diagnostic laparoscopy revealed that the ovarian enlargement was secondary to subacute appendicitis, rather than a primary adnexal process. We review the classic ultrasound and MRI imaging findings and pitfalls that relate to this diagnosis.

    Full Text Available Molecularly targeted therapy is relatively new to ovarian cancer despite the unquestionable success with these agents in other solid tumours such as breast and colorectal cancer. Advanced ovarian cancer is chemosensitive and patients can survive several years on treatment. However chemotherapy diminishes in efficacy over time whilst toxicities persist. Newer biological agents that target explicit molecular pathways and lack specific chemotherapy toxicities such as myelosuppression offer the advantage of long-term therapy with a manageable toxicity profile enabling patients to enjoy a good quality of life. In this review we appraise the emerging data on novel targeted therapies in ovarian cancer. We discuss the role of these compounds in the front-line treatment of ovarian cancer and in relapsed disease; and describe how the development of predictive clinical, molecular and imaging biomarkers will define the role of biological agents in the treatment of ovarian cancer.

    INTRODUCTION: The Nordic countries are areas with a high-incidence of ovarian cancer; however, differences between the countries exist. MATERIAL AND METHODS: We used the Danish Cancer Registry to identify 11 264 cases of ovarian cancer and 363 cases of tubal cancer during 1993-2013. We calculated...... age-standardized (world standard population) incidence rates for overall and subtype-specific ovarian cancer, and for tubal cancer. We compared age-standardized incidence rates, and 1- and 5-year age-standardized relative survival rates, respectively, for ovarian and tubal cancer combined in four...... Nordic countries using the NORDCAN database. RESULTS: The incidence rate of ovarian cancer overall in Denmark decreased statistically significantly by approximately 2.3% per year among women aged

    Full Text Available Breast masses in children, though rare, present a difficult clinical challenge as they can represent a wide variety of entities from benign fibroadenomas to phyllodes tumors. Rapidly growing or recurrent masses can be particularly concerning to patients, families and physicians alike. Clinical examination and conventional imaging modalities are not efficacious in distinguishing between different tumor types and surgical excision is often recommended for both final diagnosis and for treatment of large or rapidly growing masses. While surgical excision can result in significant long-term deformity of the breast there are some surgical techniques that can be used to limit deformity and/or aid in future reconstruction. Here we present a case of recurrent giant juvenile fibroadenoma with a review of the clinical presentation, diagnostic tools and treatment options.

  1. Recurrent Partial Words

    Full Text Available Partial words are sequences over a finite alphabet that may contain wildcard symbols, called holes, which match or are compatible with all letters; partial words without holes are said to be full words (or simply words. Given an infinite partial word w, the number of distinct full words over the alphabet that are compatible with factors of w of length n, called subwords of w, refers to a measure of complexity of infinite partial words so-called subword complexity. This measure is of particular interest because we can construct partial words with subword complexities not achievable by full words. In this paper, we consider the notion of recurrence over infinite partial words, that is, we study whether all of the finite subwords of a given infinite partial word appear infinitely often, and we establish connections between subword complexity and recurrence in this more general framework.

    Background: The study was done to compare the early pregnancy loss rate in women with polycystic ovarian syndrome who received or did not receive metformin in pregnancy. Study type, settings and duration: A case control interventional study carried out at Civil Hospital Karachi, Hamdard University Hospital and Private Gynaecology clinics from January 2005 to July 2008. Subjects and Methods Eighty two non diabetic patients with polycystic ovarian syndrome who became pregnant were included in the study. A questionnaire was filled for all patients that included information on basic demography and mean age, parity, weight. Fasting blood sugar and serum insulin levels were done for all these women. Only patients with raised insulin levels (more than 10 mu/l) were included in the study and all were offered to use oral metformin throughout pregnancy as 500 mg three times a day with folic acid supplements 5 mg once daily. Those who agreed to take the drug throughout pregnancy and to comply with the therapy were taken as cases, while those who did not agree to take the medicine acted as controls. Patients with other causes of recurrent pregnancy loss were excluded from the study. All pregnancies were followed using serial ultrasound examination to see any pregnancy loss in the two groups. Eighty two cases of polycystic ovaries with pregnancy were seen during the study period. All cases had raised serum insulin levels. Fifty patients agreed to take metformin through out pregnancy while, 32 cases did not agree to take metformin during pregnancy and thus acted as controls. The two groups did not differ in mean age, parity, weight and mean fasting blood sugar levels. Fasting insulin levels were high in metformin group (18.40 mu/l ) than in controls (12.53 mu/l). Missed abortion rate was significantly lower (12%) in metformin group than in controls (28%) (p<0.028). No congenital anomalies were found in both the groups on ultrasound at 16-19 weeks.

    Full Text Available Ovarian cancer remains one of the most aggressive gynecologic malignancies with high capacity to recur even in cases submitted to surgery with curative intent. However, even in these cases the best therapeutic option in order to achieve a good control of the disease remains radical surgery. We present the case of a 65-year-old patient diagnosed submitted to surgery for stage IIIC ovarian cancer five years before. At two years follow up she was diagnosed with an isolated recurrence at the level of the hepatic pedicle which was successfully removed. At 18 months follow up she was diagnosed with a large recurrence in the left superior abdominal quadrant and a liver metastasis which were resected. At 18 months follow up she is free of recurrent disease.

    Six years ago, I was diagnosed with stage IIIA ovarian low malignant cell potential cancer. It was the most shocking situation I have ever experienced. I didn't realize I had any symptoms, except occasional back pain, which I attributed to starting a new workout program. I had scheduled an abdominal computerized tomography (CT) scan for recurrent microscopic hematuria, which my internist wanted to check. I was told I would hear the results in two days. Two hours after my CT scan, while I was eating ice cream and watching television, an on-call genitourinary doctor (who I did not personally know) called to tell me the good news-that I had kidney stones, thus the microscopic hematuria. However, the bad news was that I had ovarian cancer that had spread to my omentum. He said he would call my gynecologist right away.

    This study compares the medium-term results of De Vega, modified De Vega, and ring annuloplasty techniques for the correction of tricuspid insufficiency and investigates the risk factors for recurrent grades 3 and 4 tricuspid insufficiency after repair. In our clinic, 93 patients with functional tricuspid insufficiency underwent surgical tricuspid repair from May 2007 through October 2010. The study was retrospective, and all the data pertaining to the patients were retrieved from hospital records. Functional capacity, recurrent tricuspid insufficiency, and risk factors aggravating the insufficiency were analyzed for each patient. In the medium term (25.4 ± 10.3 mo), the rates of grades 3 and 4 tricuspid insufficiency in the De Vega, modified De Vega, and ring annuloplasty groups were 31%, 23.1%, and 6.1%, respectively. Logistic regression analysis revealed that chronic obstructive pulmonary disease, left ventricular dysfunction (ejection fraction, tricuspid insufficiency. Medium-term survival was 90.6% for the De Vega group, 96.3% for the modified De Vega group, and 97.1% for the ring annuloplasty group. Ring annuloplasty provided the best relief from recurrent tricuspid insufficiency when compared with DeVega annuloplasty. Modified De Vega annuloplasty might be a suitable alternative to ring annuloplasty when rings are not available. PMID:23466680

    The complex nature of a variety of phenomena in physical, biological, or earth sciences is driven by a large number of degrees of freedom which are strongly interconnected. Although the evolution of such systems is described by multivariate time series (MTS), so far research mostly focuses on analyzing these components one by one. Recurrence based analyses are powerful methods to understand the underlying dynamics of a dynamical system and have been used for many successful applications including examples from earth science, economics, or chemical reactions. The backbone of these techniques is creating the phase space of the system. However, increasing the dimension of a system requires increasing the length of the time series in order get significant and reliable results. This requirement is one of the challenges in many disciplines, in particular in palaeoclimate, thus, it is not easy to create a phase space from measured MTS due to the limited number of available obervations (samples). To overcome this problem, we suggest to create recurrence networks from each component of the system and combine them into a multiplex network structure, the multiplex recurrence network (MRN). We test the MRN by using prototypical mathematical models and demonstrate its use by studying high-dimensional palaeoclimate dynamics derived from pollen data from the Bear Lake (Utah, US). By using the MRN, we can distinguish typical climate transition events, e.g., such between Marine Isotope Stages.

    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.

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

    In a first, retrospective study, 15 patients with known ovarian carcinoma were injected with 131 I-OC 125 F(ab')2 monoclonal antibody (MAb). The sensitivity of immunoscintigraphy based on the number of the tumor sites was 67% (12/18). In a second, prospective study, 29 patients with gynecologic carcinoma were injected with 131 I-OC 125 F(ab')2 (24) or 131 I-19-9 F(ab')2 (5) MAbs according to the histologic type. Based on the number of tested anatomic sites, sensitivity was 72% and specificity 86%. In two patients injected with both 131 I-OC-125 F(ab')2 and 125 I-NS F(ab')2 (nonspecific immunoglobulin) 1 and 4 days before tumor resection, tumor uptake of the specific antibody was 2.2 and 4.5 times greater than that of NS. Immunoscintigraphic results were complementary with those of ultrasonography and computed tomography. Finally, in one patient injected successively with 131 I-OC 125 F(ab')2 and 111 In-DTPA-OC 125 F(ab')2, the recurrent tumor was visualized with both radionuclides, with 111 In providing better abdominal tumor contrast but causing much greater liver radioactivity than 131 I

    Recurrent implantation failure refers to failure to achieve a clinical pregnancy after transfer of at least four good-quality embryos in a minimum of three fresh or frozen cycles in a woman under the age of 40 years. The failure to implant may be a consequence of embryo or uterine factors. Thorough investigations should be carried out to ascertain whether there is any underlying cause of the condition. Ovarian function should be assessed by measurement of antral follicle count, FSH and anti-Mu¨llerian hormone. Increased sperm DNA fragmentation may be a contributory cause. Various uterine pathology including fibroids, endometrial polyps, congenital anomalies and intrauterine adhesions should be excluded by ultrasonography and hysteroscopy. Hydrosalpinges are a recognized cause of implantation failure and should be excluded by hysterosalpingogram; if necessary, laparoscopy should be performed to confirm or refute the diagnosis. Treatment offered should be evidence based, aimed at improving embryo quality or endometrial receptivity. Gamete donation or surrogacy may be necessary if there is no realistic chance of success with further IVF attempts. Copyright © 2013. Published by Elsevier Ltd.

  15. Polycystic ovarian disease: animal models.

    Mahajan, D K

    1988-12-01

    The reproductive systems of human beings and other vertebrates are grossly similar. In the ovary particularly, the biochemical and physiologic processes are identical not only in the formation of germ cells, the development of primordial follicles and their subsequent growth to Graafian follicles, and eventual ovulation but also in anatomic structure. In a noncarcinogenic human ovary, hypersecretion of androgen causes PCOD. Such hypersecretion may result from a nonpulsatile, constant elevated level of circulating LH or a disturbance in the action of neurotransmitters in the hypothalamus. In studying the pathophysiology of PCOD in humans, one must be aware of the limitations for manipulating the hypothalamic-pituitary axis. Although the rat is a polytocous rodent, the female has a regular ovarian cyclicity of 4 or 5 days, with distinct proestrus, estrus, and diestrus phases. Inasmuch as PCOD can be experimentally produced in the rat, that species is a good model for studying the pathophysiology of human PCOD. These PCOD models and their validity have been described: (1) estradiol-valerate, (2) DHA, (3) constant-light (LL), and (4) neonatally androgenized. Among these, the LL model is noninvasive and seems superior to the others for study of the pathophysiology of PCOD. The production of the polycystic ovarian condition in the rat by the injection of estrogens or androgens in neonate animals, or estradiol or DHA in adult rats, or the administration of antigonadotropins to these animals all cause a sudden appearance of the persistent estrus state by disturbing the metabolic and physiologic processes, whereas exposure of the adult rat to LL causes polycystic ovaries gradually, similar to what is seen in human idiopathic PCOD. After about 50 days of LL, the rat becomes anovulatory and the ovaries contain thickened tunica albuginea and many atretic follicles, and the tertiary follicles are considerably distended and cystic. The granulosa and theca cells appear normal

    The recurrence rate of pheochromocytoma after adrenalectomy is 6.5-16.5%. This study aims to identify predictors of recurrence and optimal biochemical testing and imaging for detecting the recurrence of pheochromocytoma. In this retrospective study we reviewed all patients who underwent adrenalectomy for pheochromocytoma during a 14-year period at a single institution. One hundred thirty-five patients had adrenalectomy for pheochromocytoma. Eight patients (6%) developed recurrent disease. The median time from initial operation to diagnosis of recurrence was 35 months. On multivariate analysis, tumor size >5 cm was an independent predictor of recurrence. One patient with recurrence died, 4 had stable disease, 2 had progression of disease, and 1 was cured. Recurrence was diagnosed by increases in plasma and/or urinary metanephrines and positive imaging in 6 patients (75%), and by positive imaging and normal biochemical levels in 2 patients (25%). Patients with large tumors (>5 cm) should be followed vigilantly for recurrence. Because 25% of patients with recurrence had normal biochemical levels, we recommend routine imaging and testing of plasma or urinary metanephrines for prompt diagnosis of recurrence.

    What are the recurrence and pregnancy rates in women managed for ovarian endometrioma by ablation using plasma energy with and without associated surgery for colorectal endometriosis? Concomitant management of colorectal endometriosis does not impact either risk of recurrences or probability of pregnancy in women managed for endometrioma ablation using plasma energy. No consensus exists on how best to manage patients presenting with ovarian endometriomas and colorectal endometriosis, in terms of impact on fertility preservation and recurrence rates. A prospective series of consecutive patients managed for ovarian endometriomas by ablation using plasma energy, over a period of 48 consecutive months. The study included patients with associated colorectal endometriosis (n = 52) and those who were free of colorectal localizations of the disease (n = 72). No women were lost to follow-up. The 124 women included in this study were managed for either unilateral or bilateral ovarian endometriomas using plasma energy at a university tertiary care center. Recurrences and pregnancy rate were compared in patients with and without colorectal endometriosis. The minimum length of follow-up was 1 year. Cyst recurrences were assessed using pelvic ultrasound and magnetic resonance imaging. Kaplan-Meier and actuarial life-table analysis were used to estimate the recurrence-free survival curve and the probability of pregnancy. The Cox model was used to assess independent predictive factors for recurrences. Pregnancy likelihood and independent predictors were estimated using a regression logistic model. Mean follow-up was 32 ± 18 months. Forty-eight patients (40.3%) were presumed infertile and attended an assisted reproductive techniques (ART) center. Eighteen patients presented with a recurrence (14.5%). Bilateral localization of endometriomas was the only factor independently related to an increased risk of recurrences [hazard ratio 3.3, 95% confidence interval (CI) 1.2-9.4]. Of the

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

    To determine if persistent ovarian masses in pregnancy are associated with increased adverse outcomes. This is a retrospective cohort of 126 pregnant women with a persistent ovarian mass measuring 5 cm or greater who delivered at two university hospitals between 2001 and 2009. Maternal outcomes included gestational age (GA) at diagnosis, delivery and surgery as well as miscarriage, preterm birth (PTB), ovarian torsion and hospital admission for pain. Neonatal outcomes included birth weight, respiratory distress syndrome (RDS), intra-ventricular hemorrhage (IVH), death and sepsis. A total of 1225 ovarian masses were identified (4.9%) in 24,868 patients. A persistent ovarian mass was found in 0.7%. Average GA at diagnosis was 17.8 weeks. Miscarriage rate was 3.3%. Average GA at delivery was 37.9 weeks. Of the patients, 8.5% had ovarian torsion, 10.3% had admission for pain and 9.3% had PTBs. The mean cesarean delivery rate was 46.3%. The average neonatal weight was 3273 g. There was one neonatal death in this cohort. The rate of RDS was 2.8%, IVH 0.9% and neonatal sepsis 1.9%. The most common surgical pathologic diagnosis was dermoids (37.6%). No overt malignancies were seen. A persistent ovarian mass in pregnancy does not confer an increased risk of adverse pregnancy outcomes.

    Full Text Available Objective: Psoriasis is a multi-systemic chronic inflammatory skin disease. Previous data suggests that women with some chronic inflammatory diseases have diminished ovarian reserve. This study explores ovarian reserve in patients with psoriasis. Materials and methods: We prospectively analyzed 14 female patients with psoriasis and 35 healthy age and body mass index matched controls. An interview explored demographic characteristics, obstetrical history and menstrual characteristics. Psoriatic area severity index (PASI in patients was assessed. Estrogen, follicle-stimulating hormone (FSH, luteinizing hormone (LH, thyroid stimulating hormone and with gynecologic ultrasonography, ovarian volume and antral follicular count (AFC were measured in both study and control groups. These values were analyzed with changes of the PASI in the patient group. Results: Patients with psoriasis had significantly higher levels of FSH and FSH/LH ratio than healthy controls (p = 0.039, p = 0.005 respectively. AFC of psoriasis patients were significantly lower than healthy controls (p = 0.002.There were no significant difference among other hormone levels and ovarian volumes (p > 0.05. The hormone levels, ovarian volume and AFC were not correlated with PASI of the patients. Conclusion: The results of the study suggest that patients with psoriasis may have diminished ovarian reserve.

    Full Text Available Ovarian hemangioma is a rare benign tumor of female genital tract. Stromal luteinization in ovarian hemangioma is an uncommon process and the pathogenesis is controversial. In this regard, two hypotheses have been suggested whether luteinization is a reactive process or it is the stimulator for development of ovarian hemangioma. Here, we report a case of a 55-year-old woman who referred to our center due to incidental finding of left ovarian mass in pelvic sonography. Microscopically, the mass showed a mixed cavernous and capillary hemangioma and the peripheral stroma contained several small and large clusters of stromal cells, which were luteinized. It should be noted that an ovarian hemangioma could be associated with stromal luteinization although its pathogenesis is not clearly known. Yet, we believe the stromal luteinization around ovarian hemangioma could be a reactive phenomenon.

  4. ALDH1-high ovarian cancer stem-like cells can be isolated from serous and clear cell adenocarcinoma cells, and ALDH1 high expression is associated with poor prognosis.

    Directory of Open Access Journals (Sweden)

    Takafumi Kuroda

    Full Text Available Cancer stem-like cells (CSCs/cancer-initiating cells (CICs are defined as a small population of cancer cells that have high tumorigenicity. Furthermore, CSCs/CICs are resistant to several cancer therapies, and CSCs/CICs are therefore thought to be responsible for cancer recurrence after treatment and distant metastasis. In epithelial ovarian cancer (EOC cases, disease recurrence after chemotherapy is frequently observed, suggesting ovarian CSCs/CICs are involved. There are four major histological subtypes in EOC, and serous adenocarcinoma and clear cell adenocarcinoma are high-grade malignancies. We therefore analyzed ovarian CSCs/CICs from ovarian carcinoma cell lines (serous adenocarcinoma and clear cell adenocarcinoma and primary ovarian cancer cells in this study. We isolated ovarian CSCs/CICs as an aldehyde dehydrogenase 1 high (ALDH1(high population from 6 EOC cell lines (3 serous adenocarcinomas and 3 clear cell adenocarcinomas by the ALDEFLUOR assay. ALDH1(high cells showed greater sphere-forming ability, higher tumorigenicity and greater invasive capability, indicating that ovarian CSCs/CICs are enriched in ALDH1(high cells. ALDH1(high cells could also be isolated from 8 of 11 primary ovarian carcinoma samples. Immunohistochemical staining revealed that higher ALDH1 expression levels in ovary cancer cases are related to poorer prognosis in both serous adenocarcinoma cases and clear cell adenocarcinoma cases. Taken together, the results indicate that ALDH1 is a marker for ovarian CSCs/CICs and that the expression level of ALDH1 might be a novel biomarker for prediction of poor prognosis.

  5. Genetics of polycystic ovarian syndrome.

    2005-06-01

    Polycystic ovarian syndrome (PCOS) is a reproductive system disorder characterized by irregular menses, anovulation, clinical and/or biochemical signs of hyperandrogenism (hirsutism and/or acne), ovarian micropolycystic appearance and metabolic abnormalities, such as hyperinsulinaemia and obesity. The aetiopathogenesis of this syndrome is not well known. Several pathogenetic hypotheses have been proposed to explain the full array of symptoms and signs, but with elusive results. A genetic abnormality causing PCOS is supported by the observation that different members of the same family are often affected, and about half of the sisters of PCOS women have elevated serum testosterone concentrations. Therefore, the presence of gene abnormalities in women with PCOS has been widely explored in the attempt to establish whether their mutations or polymorphisms may cause PCOS. The main genes evaluated are those involved in steroidogenesis, steroid hormone effects, gonadotrophin release regulation and action, insulin secretion and action, and adipose tissue metabolism. Despite the vast body of literature produced, none of the genes evaluated seems to play a key role in PCOS pathogenesis. It is likely that PCOS may represent the final outcome of different, deeply inter-related genetic abnormalities that influence each other and perpetuate the syndrome.

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

  7. Stress and recurrent miscarriage.

    Science.gov (United States)

    Craig, M

    2001-09-01

    Our current understanding into the role of stress in unexplained recurrent miscarriages comes from two different research strategies. The majority of research has examined the role of psychological support within this patient population. This support has been provided in a number of ways ranging from weekly interviews with a psychiatrist or gynaecologist and or visual re-assurance in the form of ultrasound scans. A comparison of psychological support with an absence of such intervention has found differences in successful pregnancy outcome varying from as great as 84 versus 26%, respectively. It has been assumed that psychological support reduces the miscarriage rate by reducing “stress”within this patient population. In addition it provides indirect support for a role of stress in the aetiology of unexplained recurrent miscarriage. Other studies have attempted to directly assess the effect of personality characteristics on miscarriage rate; these studies have yielded conflicting results.The mechanism by which stress may be causal in the aetiology of unexplained recurrent miscarriage has not been examined in humans. Animal studies, however, have found that psychological distress can alter immune parameters that may be intricately involved with implantation. These parameters include an elevation of the “abortive” cytokine TNF-a and a reduction in the “anti-abortive” cytokine TGF-P2. Cells that are involved in the release of TNF-a at the feto-maternal interface include T cells, macrophages and mast cells.Mechanisms through which stress may act on these cells are explored and an integrated model is postulated.

    This report describes a rare case of recurrent bilateral focal myositis and its successful treatment via methotrexate. A 38-year-old man presented myalgia of the right gastrocnemius in May 2005. Magnetic resonance imaging showed very high signal intensity in the right gastrocnemius on short-tau inversion recovery images. A muscle biopsy revealed inflammatory CD4+ cell-dominant myogenic change. Focal myositis was diagnosed. The first steroid treatment was effective. Tapering of prednisolone, however, repeatedly induced myositis relapse, which progressed to multiple muscle lesions of both lower limbs. Initiation of methotrexate finally allowed successful tapering of prednisolone, with no relapse in the past 4 years.

    Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

    Full Text Available Equine Recurrent Airway Obstruction (RAO, also known as heaves or broken wind, is one of the most common disease in middle-aged horses. Inflammation of the airway is inducted by organic dust exposure. This disease is characterized by neutrophilic inflammation, bronchospasm, excessive mucus production and pathologic changes in the bronchiolar walls. Clinical signs are resolved in 3-4 weeks after environmental changes. Horses suffering from RAO are susceptible to allergens throughout their lives, therefore they should be properly managed. In therapy the most importanthing is to eliminate dustexposure, administration of corticosteroids and use bronchodilators to improve pulmonary function.

    Ovarian function was studied in 18 female patients treated for abdominal tumours during childhood. All received abdominal radiotherapy as part of their treatment and were studied between 1 and 26 years after irradiation. The serum gonadotrophins and oestradiol levels were consistent with ovarian failure in each case and there was a disproportionate elevation in serum follicle stimulating hormone (FSH) when compared to serum luteinizing hormone (LH) in 16. In 2 patients, the radiotherapeutic field extended downwards only as far as the sacral promontory. However, these 2 girls show similar evidence of ovarian failure to that in the other 16. (author)

    2008-01-01

    Full Text Available Abstract Background Taxane-platinum therapy (TP has replaced platinum-based therapy (PC or PAC, DNA damaging chemotherapy in the postoperative treatment of ovarian cancer patients; however, it is not always effective. TP53 protein plays a differential role in response to DNA-damaging agents and taxanes. We sought to define profiles of patients who benefit the most from TP and also of those who can be treated with PC. Methods We compared the effectiveness of PC/PAC (n = 253 and TP (n = 199 with respect to tumor TP53 accumulation in ovarian cancer patients with FIGO stage IIB-IV disease; this was a non-randomized retrospective study. Immunohistochemical analysis was performed on 452 archival tumors; univariate and multivariate analysis by the Cox's and logistic regression models was performed in all patients and in subgroups with [TP53(+] and without TP53 accumulation [TP53(-]. Results The advantage of taxane-platinum therapy over platinum-based therapy was seen in the TP53(+, and not in the TP53(- group. In the TP53(+ group taxane-platinum therapy enhanced the probability of complete remission (p = .018, platinum sensitivity (p = .014, platinum highly sensitive response (p = .038 and longer survival (OS, p = .008. Poor tumor differentiation diminished the advantage from taxane-platinum therapy in the TP53(+ group. In the TP53(- group PC/PAC was at least equally efficient as taxane-platinum therapy and it enhanced the chance of platinum highly sensitive response (p = .010. However, in the TP53(- group taxane-platinum therapy possibly diminished the risk of death in patients over 53 yrs (p = .077. Among factors that positively interacted with taxane-platinum therapy in some analyses were endometrioid and clear cell type, FIGO III stage, bulky residual tumor, more advanced age of patient and moderate tumor differentiation. Conclusion Our results suggest that taxane-platinum therapy is particularly justified in patients with TP53(+ tumors or older

    2011-01-01

    Full Text Available Angioleiomyomas are vascular variant of leiomyomas which are benign tumors of smooth muscle. They are exceedingly rare in the oral cavity. Malignant transformation of these tumors has also been reported occasionally which warrants knowledge of this soft tissue tumor. A 57 year old male patient reported with a 15 day history of an asymptomatic growth that had started insidiously in his lower left back tooth region. Clinical examination revealed a solitary, oval, sessile growth in the mandibular left retro molar region. Excisional biopsy was suggestive of Angioleiomyoma. A recurrence of the same was noted two months later which was also histopathologically reported as Angioleiomyoma. The same was confirmed using special stains. This case reports an unusual presentation of Angioleiomyoma with regards to both recurrence as well as rapid growth. It is important to be well aware of this uncommon entity as these tumors often can mimic or transform into malignancy. Precise clinicopathological examinations are therefore invaluable in establishing an accurate diagnosis and delivering suitable treatment.

    The hypothesis on the pathogenesis of epithelial ovarian cancer continues to evolve. Although epithelial ovarian cancer had been assumed to arise from the coelomic epithelium of the ovarian surface, it is now becoming clearer that the majority of serous carcinomas arise from epithelium of the distal fallopian tube, whereas clear cell and endometrioid cancers arise from endometriosis. Molecular and genomic characteristics of epithelial ovarian cancer have been extensively investigated. Our understanding of pathogenesis of the various histologic types of ovarian cancer have begun to inform changes to the strategies for management of epithelial ovarian cancer, which represent a paradigm shift not only for treatment but also for prevention, which previously had not been considered achievable. In this article, we will discuss novel attempts at the prevention of high-grade serous ovarian cancer and treatment strategies for two distinct entities in epithelial ovarian cancer: low-grade serous and clear cell ovarian carcinomas, which are relatively rare and resistant to conventional chemotherapy.

  20. DC-CIK cells derived from ovarian cancer patient menstrual blood activate the TNFR1-ASK1-AIP1 pathway to kill autologous ovarian cancer stem cells.

    2018-03-22

    Ovarian cancer stem cells (OCSCs) are highly carcinogenic and have very strong resistance to traditional chemotherapeutic drugs; therefore, they are an important factor in ovarian cancer metastasis and recurrence. It has been reported that dendritic cell (DC)-cytokine-induced killer (CIK) cells have significant killing effects on all cancer cells across many systems including the blood, digestive, respiratory, urinary and reproductive systems. However, whether DC-CIK cells can selectively kill OCSCs is currently unclear. In this study, we collected ovarian cancer patient menstrual blood (OCPMB) samples to acquire mononuclear cells and isolated DC-CIK cells in vitro. In addition, autologous CD44+/CD133+ OCSCs were isolated and used as target cells. The experimental results showed that when DC-CIK cells and OCSCs were mixed and cultured in vitro at ratios of 5:1, 10:1 and 50:1, the DC-CIK cells killed significant amounts of OCSCs, inhibited their invasion in vitro and promoted their apoptosis. The qPCR and Western blot results showed that DC-CIK cells stimulated high expression levels and phosphorylation of TNFR1, ASK1, AIP1 and JNK in OCSCs through the release of TNF-α. After the endogenous TNFR1 gene was knocked out in OCSCs using the CRISPR/Cas9 technology, the killing function of DC-CIK cells on target OCSCs was significantly attenuated. The results of the analyses of clinical samples suggested that the TNFR1 expression level was negatively correlated with ovarian cancer stage and prognosis. Therefore, we innovatively confirmed that DC-CIK cells derived from OCPMB could secret TNF-α to activate the expression of the TNFR1-ASK1-AIP1-JNK pathway in OCSCs and kill autologous OCSCs. © 2018 The Authors.

    Castelo-Branco, Camil; del Pino, Marta; Valladares, Esther

    2009-08-01

    This report considers a highly exceptional case of ovarian hyperstimulation syndrome due to a gonadotroph adenoma secreting LH in a 31-year-old patient who presented with amenorrhoea and galactorrhoea syndrome and a complex bilateral ovarian mass. Magnetic resonance imaging revealed a pituitary adenoma, and laboratory tests corroborated the hyperprolactinaemia without other hormonal pituitary abnormalities. Ovarian hyperstimulation syndrome due to a gonadotroph adenoma with normal gonadotrophins is extremely rare. Most of the described cases are caused by FSH adenomas. Due to the originality of the case, it was considered useful for understanding the management of this entity, and it is proposed that LH adenomas should also be considered in the differential diagnosis of patients with spontaneous ovarian hyperstimulation syndrome.

    Lee, Alice W; Tyrer, Jonathan P; Doherty, Jennifer A

    2015-01-01

    OBJECTIVE: Ovarian cancer is a hormone-related disease with a strong genetic basis. However, none of its high-penetrance susceptibility genes and GWAS-identified variants to date are known to be involved in hormonal pathways. Given the hypothesized etiologic role of gonadotropins, an assessment...... of how variability in genes involved in the gonadotropin signaling pathway impacts disease risk is warranted. METHODS: Genetic data from 41 ovarian cancer study sites were pooled and unconditional logistic regression was used to evaluate whether any of the 2185 SNPs from 11 gonadotropin signaling pathway...... genes was associated with ovarian cancer risk. A burden test using the admixture likelihood (AML) method was also used to evaluate gene-level associations. RESULTS: We did not find any genome-wide significant associations between individual SNPs and ovarian cancer risk. However, there was some...

    Laparoscopic ovarian drilling (LOD) has been put forward as the treatment of choice in women with clomiphene citrate (CC)-resistant polycystic ovary syndrome (PCOS), with tubo-ovarian adhesion formation as the major disadvantage. Our study proposed to compare the efficacy of laparoscopic unilateral ovarian drilling with bilateral ovarian drilling in terms of ovulation and pregnancy rate with the expected advantage of decreasing postoperative adhesion rate and change in fimbiro ovarian relationship with unilateral drilling. This prospective randomized study included 44 patients with anovulatory infertility due to PCOS. Twenty-two patients underwent unilateral ovarian drilling in group-I and 22 patients underwent bilateral ovarian drilling in group-II between June 2005 and June 2007. The number of drilling site in each ovary was limited to five. The clinical and biochemical response, ovulation and pregnancy rates over a follow-up period of 1 year were compared. Tubo-ovarian adhesion rate was compared during cesarean section or during repeat laparoscopy. There was no statistical difference between the two groups in terms of clinical and biochemical response, ovulation rate and pregnancy rate. Postoperatively, tubo-ovarian adhesions could be assessed in 36.3% of the patients and no adhesions were found in a single case in either group. Unilateral drilling cauterization of ovary is equally efficacious as bilateral drilling in inducing ovulation and achieving pregnancy. Unilateral ovarian drilling may be a suitable option in clomiphene citrate resistant infertility patient of PCOS which can replace bilateral ovarian drilling with the potential advantage of decreasing the chances of adhesion formation.

    Full Text Available Abstract Background There is no consensus regarding the management of ovarian cancer patients, who have shown complete clinical response (CCR to primary therapy and have rising cancer antigen CA-125 levels but have no symptoms of recurrent disease. The present study aims to determine whether follow-up CA-125 levels can be used to identify the need for imaging studies and secondary cytoreductive surgery (CRS. Methods We identified 410 ovarian cancer patients treated at The University of Texas MD Anderson Cancer Center between 1984 and 2011. These patients had shown CCR to primary therapy. Follow-up was conducted based on the surveillance protocol of the MD Anderson Cancer Center. We used the Cox proportional hazards model and log-rank test to assess the associations between the follow-up CA-125 levels and secondary CRS and survival duration. Results The CA-125 level of 1.68 × nadir was defined as the indicator of recurrent disease (p  1.68 × nadir at relapse (55.7 and 10.4 months; p = 0.04 and 0.01, respectively. The overall and progression free survival duration of patients with asymptomatic relapse and underwent a secondary CRS was longer than that of patients with symptomatic relapse (p = 0.02 and 0.04 respectively. Conclusions The increase of serum CA-125 levels is an early warning of clinical relapse in ovarian cancer. Using CA-125 levels in guiding the treatment of patients with asymptomatic recurrent ovarian cancer, who have shown CCR to primary therapy, can facilitate optimal secondary CRS and extend the survival duration of the patients.

    Borderline ovarian tumors are typically indolent neoplasms. Since many are diagnosed in younger women, fertility conservation is an important consideration and has been advocated based on retrospective data. The objective of this study was to identify features impacting on recurrence and survival in a series of borderline ovarian tumors, and to assess the safety of a fertility-sparing approach. A historical cohort study of consecutive borderline ovarian tumors cases treated at a single institution over 30 years (1981-2011). Data on surgical approach (fertility-sparing or otherwise), disease stage, CA125 levels, histological features, adjuvant treatment and follow-up data were collected. Recurrence and survival were assessed using the Kaplan-Meier method and associations with the variables of interest were evaluated using a multivariate Cox proportional hazards model. 213 patients were included. Of 132 women age 40 years and below at diagnosis, 112 (85%) had a fertility-sparing procedure and 60 (46%) had conservation of an involved ovary. Fifty patients (24%) developed recurrences; fertility preservation (hazard ratio = 2.57; 95% confidence interval 1.1-6; p = 0.029) and advanced stage (hazard ratio = 4.15; 95% confidence interval 2.3-7.6; p Fertility preservation was not associated with compromised survival. Borderline ovarian tumors carry a good prognosis overall. Fertility preservation is associated with a higher risk of disease relapse; however, as most relapses are localized and may be salvaged with surgical treatment, overall survival is not compromised. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    A recent pathological and epidemiological study on females with ovarian neoplasms among the Radiation Effects Research Foundation (RERF) Life Span Study (LSS) Extended Sample ascertained 194 malignant and 106 benign ovarian tumor cases which had occurred during the period 1950 - 80. Of the 194 cases of ovarian cancer, 128 (66 %) were reviewed microscopically and the age-adjusted incidence of ovarian cancer revealed a statistically significant linear increase with increasing exposure dose, both in microscopically reviewed and in all cases. The radiation-related excess of ovarian cancer appeared to be highest in women less than 20 years of age when exposed, with these women having the longest latent period for tumor development, compared to the older age groups. The histological distribution of cancer types among exposed individuals appeared not very different from that seen in the general population. The analysis of 106 autopsy subjects with benign ovarian tumors, of which 89 were reviewed microscopically, depicted a trend of increasing radiation-related tumor excess with increasing exposure dose among exposed cases, though the trend is not statistically significant when observation was limited to microscopically reviewed subjects. The histological distribution of benign tumor types among exposed cases appeared not very different from that seen in the general population. The findings are consistent with a hypothesis that radiation-injured ovaries in association with secondary excess of gonadotrophic hormones are important causative factors in the development of ovarian tumors, which has been suggested by experimental findings concerning the induction of ovarian tumors by ionizing radiation and by a recent analysis of breast carcinogenesis in exposed females of Hiroshima and Nagasaki.

    Epithelial ovarian cancer frequently presents at an advanced stage where the cornerstone of management remains surgery and platinum-based chemotherapy. Unfortunately, despite sometimes dramatic initial responses, advanced ovarian cancer almost invariably relapses. Little progress has been made in the identification of effective targeted-therapies for ovarian cancer. The majority of clinical trials investigating novel agents have been negative and the only approved targeted-therapy is bevacizumab, for which reliable predictive biomarkers still elude us. Ovarian cancer is treated as a uniform disease. Yet, biological studies have highlighted the heterogeneity of this malignancy with marked differences in histology, oncogenesis, prognosis, chemo-responsiveness, and molecular profile. Recent high throughput molecular analyses have identified a huge number of genomic/phenotypic alterations. Broadly speaking, high grade serous carcinomas (type II) display significant genomic instability and numerous amplifications and losses; low grade (type I) tumors are genomically stable but display frequent mutations. Importantly, many of these genomic alterations relate to known oncogenes for which targeted-therapies are available or in development. There is today a real potential for personalized medicine in ovarian cancer. We will review the current literature regarding the molecular characterization of epithelial ovarian cancer and discuss the biological rationale for a number of targeted strategies. In order to translate these biological advances into meaningful clinical improvements for our patients, it is imperative to incorporate translational research in ovarian cancer trials, a number of strategies will be proposed such as the acquisition of quality tumor samples, including sequential pre- and post-treatment biopsies, the potential of liquid biopsies, and novel trial designs more adapted to the molecular era of ovarian cancer research.

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

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

    We integrate the recently proposed spatial transformer network (SPN) [Jaderberg et. al 2015] into a recurrent neural network (RNN) to form an RNN-SPN model. We use the RNN-SPN to classify digits in cluttered MNIST sequences. The proposed model achieves a single digit error of 1.5% compared to 2.......9% for a convolutional networks and 2.0% for convolutional networks with SPN layers. The SPN outputs a zoomed, rotated and skewed version of the input image. We investigate different down-sampling factors (ratio of pixel in input and output) for the SPN and show that the RNN-SPN model is able to down-sample the input...

It represents an important differential diagnosis of pelvic tumors in women of reproductive age. This study aims to describe a case of ag- gressive angiomyxoma.Case report: woman, 37 years old, complained about a bulge on the right perianal region, and anal itching and burning, bleeding, tenesmus and incontinence. The proctologic examina- tion confirmed the perianal bulge and extrinsic compression of the posterior wall of the rectum. Computed tomography (CT of the pelvis showed a well-defined pelvic mass ex- tending to the right rectal area. Exploratory laparotomy showed a mass of fibro elastic con- sistency adjacent to the pelvic organs and closely attached to the distal rectum, and per- formed a resection of the pelvic tumor afterward. Anatomopathological analysis revealed an aggressive angiomyxoma. Magnetic resonance imaging (MRI of the pelvis showed signs of recurrence in the pelvic cavity on the right side of the rectum. A surgical procedure was performed to resect the lesion. After an asymptomatic period, the MRI showed solid growths located in the right ischiorectal fossa. A new surgical procedure identified only retention cysts in the pelvis and right ischiorectal fossa, only lysis of adhesions was per- formed. The patient is currently undergoing follow-up without disease recurrence.

    Frilot, Clifton; Kim, Paul Y.; Carrubba, Simona; McCarty, David E.; Chesson, Andrew L.; Marino, Andrew A.

    Analysis of Brain Recurrence (ABR) is a method for extracting physiologically significant information from the electroencephalogram (EEG), a non-stationary electrical output of the brain, the ultimate complex dynamical system. ABR permits quantification of temporal patterns in the EEG produced by the non-autonomous differential laws that govern brain metabolism. In the context of appropriate experimental and statistical designs, ABR is ideally suited to the task of interpreting the EEG. Present applications of ABR include discovery of a human magnetic sense, increased mechanistic understanding of neuronal membrane processes, diagnosis of degenerative neurological disease, detection of changes in brain metabolism caused by weak environmental electromagnetic fields, objective characterization of the quality of human sleep, and evaluation of sleep disorders. ABR has important beneficial implications for the development of clinical and experimental neuroscience.

  4. Environmental and developmental origins of ovarian reserve.

    Richardson, M C; Guo, M; Fauser, B C J M; Macklon, N S

    2014-01-01

    BACKGROUND Oocyte number is established early in life before a gradual loss of this ovarian reserve during reproductive life until oocyte availability becomes limiting at the menopause. Although there is a large genetic component to the ovarian reserve achieved before birth, other influences including the maternal endocrine and nutritional milieu, and environmental factors may represent important developmental determinants. Environmental and nutritional factors may also modify the downward trajectory of ovarian reserve in adult life. The combination of these early and later life influences has the potential to lead to diminished ovarian reserve, compromising fertility in later reproductive years and altering age at natural menopause. METHODS Literature searches of the ISI Web of Knowledge database were carried out using the main terms 'ovarian reserve' and 'menopause AND age' in conjunction with a range of other terms encompassing a variety of factors with potential effects on ovarian reserve. The various searches were inspected manually and the relevant papers selected for critical analysis and interpretation. RESULTS Evidence was identified supporting the view that elevated prenatal androgens have an adverse effect on the early establishment of ovarian reserve, although the implications for ovarian reserve in the polycystic ovary syndrome (which may also be programmed through prenatal androgen exposure) remain uncertain. Recent evidence is cited suggesting that effects of maternal nutrient restriction on ovarian reserve may also involve changes in prenatal androgen exposure. A general rationale is developed through examination of evidence which emphasizes the roles of the aryl hydrocarbon receptor (AHR) and the estrogen receptor (ER) systems in ovarian reserve modulation. Because of their similarity to the natural ligands, many environmental compounds have the ability to bind to these receptors (albeit at lower affinities) and thereby have the potential to

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

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

    2017-09-01

    Full Text Available Polycystic ovarian syndrome (PCOS is one of the most common causes of infertility in women. Surgical treatment of PCOS, either by the antiquated wedge resection or ovarian drilling, is one of the commonly used lines in developing countries due to its low-cost. Premature ovarian failure and diminished ovarian reserve are serious complications of the surgical treatment but no published reports sufficiently highlighted these hazards. In this case series, we report on twenty one women aged between 19–39 years, presented to Infertility Clinic, Assiut Women Health Hospital with ovarian dysfunction, diagnosed within 6–36 months after surgical management of PCOS. Nineteen of them had laparoscopic bilateral ovarian drilling using electrocauterization, and the last two had bilateral wedge resection of the ovaries through minilaparotomy. Accurate and documented diagnosis of PCOS, appropriate surgical training, adjusted thermal injury and adjusted number of punctures are essential for the avoidance of excessive damage to the ovaries. Under treatment (failure of drilling is much better than premature ovarian failure or diminishing ovarian reserve.

    Although family history of testicular cancer is well-established as a risk factor for testicular cancer, it is unknown whether family history of ovarian cancer is associated with risk of testicular cancer. Using data from the Familial Ovarian Cancer Registry on 2636 families with multiple cases of ovarian cancer, we systematically compared relative frequencies of ovarian cancer among relatives of men with testicular and non-testicular cancers. Thirty-one families with cases of both ovarian and testicular cancer were identified. We observed that, among men with cancer, those with testicular cancer were more likely to have a mother with ovarian cancer than those with non-testicular cancers (OR = 3.32, p = 0.004). Zero paternal grandmothers of men with testicular cancer had ovarian cancer. These observations provide compelling preliminary evidence for a familial association between ovarian and testicular cancers Future studies should be designed to further investigate this association and evaluate X-linkage.

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

    Lynch syndrome is a hereditary ovarian cancer with a prevalence of 0.9-2.7%. Lynch syndrome accounts for 10-15% of hereditary ovarian cancers, while hereditary breast and ovarian cancer syndrome accounts for 65-75% of these cancers. The lifetime risk for ovarian cancer in families with Lynch syndrome is ~8%, which is lower than colorectal and endometrial cancers, and ovarian cancer is not listed in the Amsterdam Criteria II. More than half of sporadic ovarian cancers are diagnosed in stage III or IV, but ≥80% of ovarian cancers in Lynch syndrome are diagnosed in stage I or II. Ovarian cancers in Lynch syndrome mostly have non-serous histology and different properties from those of sporadic ovarian cancers. A screening method for ovarian cancers in Lynch syndrome has yet to be established and clinical studies of prophylactic administration of oral contraceptives are not available. However, molecular profiles at the genetic level indicate that ovarian cancer in Lynch syndrome has a more favorable prognosis than sporadic ovarian cancer. Inhibitors of the phosphatidylinositol 3-kinase/mammalian target of the rapamycin pathway and anti-epidermal growth factor antibodies may have efficacy for the disease. To the best of our knowledge, this is the first review focusing on ovarian cancer in Lynch syndrome.

  12. Coffee, tea, and caffeine consumption and risk of epithelial ovarian cancer and borderline ovarian tumors

    2015-01-01

    BACKGROUND: Epidemiological studies that have investigated the association between coffee, tea and caffeine consumption and ovarian cancer risk have produced conflicting results. Furthermore, only few studies have examined the role of coffee and tea consumption separately for borderline ovarian...... tumors. By use of data from a large Danish population-based case-control study, we examined the risk of ovarian tumors associated with coffee, tea, and caffeine consumption with a particular focus on characterizing risks by tumor behavior and histology. MATERIAL AND METHODS: From 1995 through 1999, we....... RESULTS: Both coffee (OR = 0.90; 95% CI 0.84-0.97 per cup/day) and total caffeine consumption from coffee and tea combined (OR = 0.93; 95% CI 0.88-0.98 per 100 mg/day) decreased the risk of ovarian cancer. These associations were significant only for the serous and "other" subtypes of ovarian cancer...

    This study evaluated the diagnostic value of radioimmnoimaging (RII) with 99 Tc labeled monoclonal antibody C50, raised originally against carcinoembryonic antigen (anti-CEA) in various tumors. 152 pathologically confirmed patients with a tumor were imaged prior to surgery with an anti-CEA monoclonal antibody labeled with 99 Tc. There were 115 patients with ovarian carcinoma, 26 patients with colorectal carcinoma and 11 patients with lung carcinoma. Images were acquired at 3-6 h post injection and were analyzed by the double blind method. Images of patients with ovarian cancer were compared with B-ultrasound images. Immunohistochemical staining was performed on all cases of colorectal cancer. All RII images demonstrated excellent contrast, clear lesions, and no serious toxic or other side reactions occurred. Transient chills and fever were observed in 3 cases. This study showed a sensitivity=88.2%, specificity=83.2%, and an accuracy=4.0%. The smallest lesion size detected was 2 x 2 cm. The total combined lesion detection rate for primary, metastatic, and recurrence lesions was 84.4%. We conclude that 99 Tc labeled anti-CEA MoAb C50 can be used in the diagnosis of colorectal carcinoma, ovarian carcinoma, and lung carcinoma

    Molecular events leading to epithelial ovarian cancer are poorly understood but ovulatory hormones and a high number of life-time ovulations with concomitant proliferation, apoptosis, and inflammation, increases risk. We identified genes that are regulated during the estrous cycle in murine ovarian surface epithelium and analysed these profiles to identify genes dysregulated in human ovarian cancer, using publically available datasets. We identified 338 genes that are regulated in murine ovarian surface epithelium during the estrous cycle and dysregulated in ovarian cancer. Six of seven candidates selected for immunohistochemical validation were expressed in serous ovarian cancer, inclusion cysts, ovarian surface epithelium and in fallopian tube epithelium. Most were overexpressed in ovarian cancer compared with ovarian surface epithelium and/or inclusion cysts (EpCAM, EZH2, BIRC5) although BIRC5 and EZH2 were expressed as highly in fallopian tube epithelium as in ovarian cancer. We prioritised the 338 genes for those likely to be important for ovarian cancer development by in silico analyses of copy number aberration and mutation using publically available datasets and identified genes with established roles in ovarian cancer as well as novel genes for which we have evidence for involvement in ovarian cancer. Chromosome segregation emerged as an important process in which genes from our list of 338 were over-represented including two (BUB1, NCAPD2) for which there is evidence of amplification and mutation. NUAK2, upregulated in ovarian surface epithelium in proestrus and predicted to have a driver mutation in ovarian cancer, was examined in a larger cohort of serous ovarian cancer where patients with lower NUAK2 expression had shorter overall survival. In conclusion, defining genes that are activated in normal epithelium in the course of ovulation that are also dysregulated in cancer has identified a number of pathways and novel candidate genes that may contribute

    Ovarian cancer remains the dominant cause of death due to malignancies of the female reproductive system. The capability to identify and remove all tumors during intraoperative procedures may ultimately reduce cancer recurrence, and lead to increased patient survival. The objective of this study is to investigate the effectiveness of an optical nano-structured system for targeted near infrared (NIR) imaging of ovarian cancer cells that over-express the human epidermal growth factor receptor 2 (HER2), an important biomarker associated with ovarian cancer. The nano-structured system is comprised of genome-depleted plant-infecting brome mosaic virus doped with NIR chromophore, indocyanine green, and functionalized at the surface by covalent attachment of monoclonal antibodies against the HER2 receptor. We use absorption and fluorescence spectroscopy, and dynamic light scattering to characterize the physical properties of the constructs. Using fluorescence imaging and flow cytometry, we demonstrate the effectiveness of these nano-structures for targeted NIR imaging of HER2 receptors in vitro. These functionalized nano-materials may provide a platform for NIR imaging of ovarian cancer.

    2017-09-01

    Recurrent vulvovaginal candidiasis (RVVC), multiple episodes of vulvovaginal candidiasis (VVC; vaginal yeast infection) within a 12-month period, adversely affects quality of life, mental health, and sexual activity. Diagnosis is not straightforward, as VVC is defined by the combination of often nonspecific vaginal symptoms and the presence of yeast-which is a common vaginal commensal. Estimating the incidence and prevalence is challenging: most VVC is diagnosed and treated empirically, the availability for purchase of effective therapies over the counter enables self-diagnosis and treatment, and the duration of the relatively benign VVC symptoms is short, introducing errors into any estimates relying on medical records or patient recall. We evaluate current estimates of VVC and RVVC and provide new prevalence estimates using data from a 2011 seven-country (n = 7345) internet panel survey on VVC conducted by Ipsos Health (https://www.ipsos.com/en). We also evaluate information on VVC-associated visits using the National Ambulatory Medical Care Survey. The estimated probability of VVC by age 50 varied widely by country (from 23% to 49%, mean 39%), as did the estimated probability of RVVC after VVC (from 14% to 28%, mean 23%). However estimated, the probability of RVVC was high suggesting RVVC is a common condition. Copyright © 2017 Elsevier Inc. All rights reserved.

  10. Serum protein profile at remission can accurately assess therapeutic outcomes and survival for serous ovarian cancer.

    Directory of Open Access Journals (Sweden)

    Jinhua Wang

    Full Text Available BACKGROUND: Biomarkers play critical roles in early detection, diagnosis and monitoring of therapeutic outcome and recurrence of cancer. Previous biomarker research on ovarian cancer (OC has mostly focused on the discovery and validation of diagnostic biomarkers. The primary purpose of this study is to identify serum biomarkers for prognosis and therapeutic outcomes of ovarian cancer. EXPERIMENTAL DESIGN: Forty serum proteins were analyzed in 70 serum samples from healthy controls (HC and 101 serum samples from serous OC patients at three different disease phases: post diagnosis (PD, remission (RM and recurrence (RC. The utility of serum proteins as OC biomarkers was evaluated using a variety of statistical methods including survival analysis. RESULTS: Ten serum proteins (PDGF-AB/BB, PDGF-AA, CRP, sFas, CA125, SAA, sTNFRII, sIL-6R, IGFBP6 and MDC have individually good area-under-the-curve (AUC values (AUC = 0.69-0.86 and more than 10 three-marker combinations have excellent AUC values (0.91-0.93 in distinguishing active cancer samples (PD & RC from HC. The mean serum protein levels for RM samples are usually intermediate between HC and OC patients with active cancer (PD & RC. Most importantly, five proteins (sICAM1, RANTES, sgp130, sTNFR-II and sVCAM1 measured at remission can classify, individually and in combination, serous OC patients into two subsets with significantly different overall survival (best HR = 17, p<10(-3. CONCLUSION: We identified five serum proteins which, when measured at remission, can accurately predict the overall survival of serous OC patients, suggesting that they may be useful for monitoring the therapeutic outcomes for ovarian cancer.

  11. Are Early Relapses in Advanced-Stage Ovarian Cancer Doomed to a Poor Prognosis?

    Directory of Open Access Journals (Sweden)

    Fabien Vidal

    Full Text Available Early recurrence (ER after completion of therapeutic regimen in advanced-stage ovarian cancer is a challenging clinical situation. Patients are perceived as invariably having a poor prognosis. We investigated the possibility of defining different prognostic subgroups and the parameters implicated in prognosis of ER patients.We analyzed a multi-centric database of 527 FIGO stage IIIC and IV ovarian cancer patients. We defined patients relapsing within 12 months as ER and investigated using Cox logistic regression the prognostic factors in ER group. We subsequently divided ER patients into good and poor prognosis groups according to a lower or higher overall survival (OS at 12 months after relapse and determined parameters associated to poor prognosis.The median follow up was 49 months. One hundred and thirty eight patients recurred within 12 months. OS and Disease Free Survival (DFS were 24.6 and 8.6 months, respectively, in this group of patients. Among the ER patients, 73 had a poor prognosis with an OS after relapse below 12 months (mean OS = 5.2 months and 65 survived after one year (mean OS = 26.9 months. Residual disease (RD after debulking surgery and mucinous histological subtype negatively impacted prognosis (HR = 1.758, p = 0.017 and HR = 8.641, p = 0.001 respectively. The relative risk of death within 12 months following relapse in ER patients was 1.61 according to RD status. However, RD did not affect DFS (HR = 0.889, p = 0.5.ER in advanced-stage ovarian cancer does not inevitably portend a short-term poor prognosis. RD status after initial cytoreduction strongly modulates OS, that gives additional support to the concept of maximum surgical effort even in patients who will experience early recurrence. The heterogeneity in outcomes within the ER group suggests a role for tumor biology in addition to classical clinical parameters.

    Full Text Available

    • Gorlin syndrome (GS, also known as nevoid basal cell carcinoma syndrome (NBCCS, is a rare inherited multisystem disorder. This paper presents a 22-years-old Iranian woman with this syndrome whose past history was multiple keratocysts of maxillary bone. She was referred to gynecology clinic with the chief complaint of irregular menses and vaginal spotting. On examination, frontal bossing and hypertelorism were detected. Physical examination of genitalia disclosed bilateral adnexal masses. Pelvic ultrasound showed two solid, echogenous and calcified masses measuring 100*50*10 & 60*50*45 mm in the left and right ovaries, respectively. The patient underwent right oophorectomy and ovarian mass resection with preservation of intact ovarian tissue on the left side. On frozen and permanent histological sections, bilateral and calcified ovarian fibromas were diagnosed. Surprisingly, during the last follow-up one year after the surgery, we found that our patient was expecting a baby. It can be concluded that in the presence of bilateral and calcified ovarian fibromas, the possibility of GS should be considered. Accurate diagnosis is only possible with close attention to the familial and past medical history and physical examination. In these patients, careful follow up for detecting malignancies and other complications is highly recommended.

  2. Comprehensive serum profiling for the discovery of epithelial ovarian cancer biomarkers.

    Directory of Open Access Journals (Sweden)

    Ping Yip

    Full Text Available FDA-cleared ovarian cancer biomarkers are limited to CA-125 and HE4 for monitoring and recurrence and OVA1, a multivariate panel consisting of CA-125 and four additional biomarkers, for referring patients to a specialist. Due to relatively poor performance of these tests, more accurate and broadly applicable biomarkers are needed. We evaluated the dysregulation of 259 candidate cancer markers in serum samples from 499 patients. Sera were collected prospectively at 11 monitored sites under a single well-defined protocol. All stages of ovarian cancer and common benign gynecological conditions were represented. To ensure consistency and comparability of biomarker comparisons, all measurements were performed on a single platform, at a single site, using a panel of rigorously calibrated, qualified, high-throughput, multiplexed immunoassays and all analyses were conducted using the same software. Each marker was evaluated independently for its ability to differentiate ovarian cancer from benign conditions. A total of 175 markers were dysregulated in the cancer samples. HE4 (AUC=0.933 and CA-125 (AUC=0.907 were the most informative biomarkers, followed by IL-2 receptor α, α1-antitrypsin, C-reactive protein, YKL-40, cellular fibronectin, CA-72-4 and prostasin (AUC>0.800. To improve the discrimination between cancer and benign conditions, a simple multivariate combination of markers was explored using logistic regression. When combined into a single panel, the nine most informative individual biomarkers yielded an AUC value of 0.950, significantly higher than obtained when combining the markers in the OVA1 panel (AUC 0.912. Additionally, at a threshold sensitivity of 90%, the combination of the top 9 markers gave 88.9% specificity compared to 63.4% specificity for the OVA1 markers. Although a blinded validation study has not yet been performed, these results indicate that alternative biomarker combinations might lead to significant improvements in the

  3. Smoking may modify the association between neoadjuvant chemotherapy and survival from ovarian cancer.

    2016-01-01

    Tobacco smoking by cancer patients is associated with increased mortality. Less is known of the impact of smoking on recurrence risk and interaction with chemotherapy treatment. We examined these associations in ovarian cancer. Patients were identified from the Alberta Cancer Registry between 1978 and 2010 and were oversampled for less-common histologic ovarian tumor types. Medical records were abstracted for 678 eligible patients on lifestyle, medical and cancer treatment, and review of pathology slides was performed for 605 patients. We estimated hazard ratios (HR) and 95% confidence intervals (CI) using Cox proportional hazard models adjusted for age at diagnosis, race, stage and residual disease. Among patients receiving adjuvant chemotherapy (N=432), current smoking was significantly associated with shorter duration of overall (OS; HR, 8.56; 95% CI, 1.50-48.7) and progression-free (PFS; HR, 5.74; 95% CI, 1.05-31.4) survival from mucinous ovarian cancer only. There was no significant association between neoadjuvant chemotherapy and survival. However, among patients receiving neoadjuvant chemotherapy (N=44), current smokers had shorter PFS (HR, 4.32; 95% CI, 1.36-13.8; N=32 progressed/9 censored events) compared to never smokers, but the HRs were not statistically different across smoking categories (P interaction=0.87). Adverse associations were observed between smoking status and OS or PFS among patients with mucinous ovarian cancer receiving adjuvant chemotherapy. No significant effect was found from neoadjuvant chemotherapy on PFS overall; however, smoking may modify this association. Although needing replication, these findings suggest that patients may benefit from smoking cessation interventions prior to treatment with chemotherapy. Copyright © 2015 Elsevier Inc.

    1996-01-01

    Mondini dysplasia is a congenital malformation of the inner ear, commonly associated with hearing impairment, cerebrospinal fluid otorrhea/rhinorrhea and recurrent meningitis. Two such cases are described, with hearing impairment, cerebrospinal fluid rhinorrhea, and several episodes of meningitis. Diagnosis was confirmed by high-resolution computed tomography. After surgical correction of the malformation, there was no recurrent episode of meningitis at subsequent follow-up. To avoid the suffering and the sequelae of recurrent meningitis, an early diagnosis and prompt surgical intervention are crucial for such patients.

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

    PURPOSE: The aim of the study was to examine the potential association between a history of pelvic inflammatory disease (PID) and risk of epithelial ovarian cancer or ovarian borderline tumors. METHODS: In a population-based case-control study in Denmark, we included 554 women with invasive ovarian...... cancer, 202 with ovarian borderline tumors, and 1,564 controls aged 35-79 years. The analyses were performed in multiple logistic regression models. RESULTS: We found a significantly increased risk of ovarian borderline tumors among women with a history of PID (OR = 1.50; 95% CI 1.......08-2.08) but no apparent association between PID and risk of invasive ovarian cancer (OR = 0.83; 95% CI 0.65-1.05). We found no effect of age at time of first PID or time since first PID on the risk for either condition. CONCLUSION: Our results suggest that a history of PID is associated with an increased risk of ovarian...

    Abstract Background: This systematic review aimed at summarizing and evaluating the evidence from randomized controlled trials (RCTs) using acupuncture to treat polycystic ovarian syndrome (PCOS), specifically focusing on ovulation rate, menstrual rate, and related hormones. Methods: Fifteen databases were searched electronically through February 2016. Our review included RCTs of women with PCOS; these RCTs compared acupuncture with sham acupuncture, medication, or no treatment. Two reviewers independently extracted data. Data were pooled and expressed as mean differences (MDs) for continuous outcomes and risk ratios for dichotomous outcomes, with 95% confidence intervals (CIs) using a random-effects model. Results: We found a low level of evidence that acupuncture is more likely to improve ovulation rate (MD 0.35, 95% CI: 0.14–0.56) and menstruation rate (MD 0.50, 95% CI: 0.32–0.68) compared with no acupuncture. We found statistically significant pooled benefits of acupuncture treatment as an adjunct to medication in luteinizing hormone (LH), LH/follicular stimulating hormone (FSH) ratio, testosterone, fasting insulin, and pregnancy rates, but the level of evidence was low/very low. Conclusion: There is limited evidence to judge the efficacy and safety of acupuncture on key reproductive outcomes in women with PCOS. Large-scale, long-term RCTs with rigorous methodological input are needed. PMID:28591042

    Background: Polycystic ovarian syndrome (PCOS) is the commonest cause of secondary infertility. Laparoscopic ovarian drilling has widely been used for induction of ovulation in polycystic ovarian syndrome patients resistant to clomiphene citrate. 80% patients ovulated after treatment and 60% patient conceived either spontaneously or after treatment with medication to which they are previously resistant. Purpose: The aim of the present study was to see the effectiveness of laparoscopic ovarian drilling (LOD) with monopolar diathermy on pregnancy outcome in infertile women with polycystic ovarian syndrome (PCOS). Design: Descriptive cross sectional study. Intervention: Laparoscopic ovarian drilling. Main Outcome Measures: Pregnancy, ovulation rate. Material and Methods: This study was carried out in the department of Gynae and Obstetrics in Sharif Medical City Hospital from January, 2007 to January, 2009. The inclusion criteria for laparoscopy ovarian drilling (LOD) were those infertile women between the age group of 25 - 38 years who meet the criteria for PCOS and who are resistant to clomiphene citrate and injectable gonadotrophins. A total of 30 women were booked for laparoscopic ovarian drilling after having informed consent for procedure. Response to therapy was assessed in term of pregnancy outcome and ovulation rate for 1 year after therapy. Results: A total of 30 patients were booked for laparoscopic ovarian drilling from January, 2007 to January, 2009. The mean age of study group was 30 years +- SD 4.7791. Cumulative ovulation rate was observed in 22 patients (73%), out of which spontaneous ovulation occurred in 18 patients (80%), and after ovulation induction therapy in 4 patients (18%). Eleven patients (37%) conceived in two year duration. Spontaneous conception without any treatment was observed in 7 patients (63%); however 4 patients (37%) require further assistance with combined therapy of clomiphene citrate and injectable gonadotrophins after failure

    A 32-year-old female who suffered from abdominal pain underwent 18 F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the diagnostic workup of pelvic mass lesions. Cystic mass lesions in the bilateral ovaries showed wall thickening and intense hypermetabolism along the rim. In addition, multifocal intense hypermetabolic lymphadenopathies were seen in the left paraaortic lymph node (LN), aortocaval LN, and both common iliac LNs. We interpreted these findings as bilateral ovarian cancer with retroperitoneal metastatic lymphadenopathies rather than endometriosis with reactive lymphadenopathies rather than endometriosis with reactive lymphadenopathies. However, Histopathological examination confirmed the ovarian mass lesions as tubo-ovarian abscesses. We report a case that even if simultaneous hypermetabolic retroperitoneal LNs are seen, intense hypermetabolic lesions in both ovaries can be in consequence of inflammatory change

    Full Text Available Ovarian torsion (also termed as adnexal torsion refers to partial or complete rotation of the ovary and a portion of fallopian tube along its supplying vascular pedicle. It occurs commonly in reproductive age group; more on the right side (60% and often presents with acute lower abdominal pain lasting for few hours and up to 24 h, accounting for 2.7% of acute gynecological conditions. It is one of the devastating conditions, hampering blood supply of ovary which may lead to total necrosis of ovarian tissue and complications, if not diagnosed and managed in time. Hence, we present a case on a twisted ovarian cyst in postmenopausal woman with unusual symptomatology leading to delayed diagnosis and loss of an ovary.

    2015-02-01

    Full Text Available We report a case of a 19-year-old woman with multicystic peritoneal mesothelioma (MCPM who had previously undergone left adnexectomy due to an ovarian tumor of borderline malignancy at the age of 17 years. Follow-up imaging studies after adnexectomy revealed multiple cystic lesions of increasing size and number, suggesting recurrence of the tumor. Diagnostic laparoscopic surgery was performed, and the cystic lesion was pathologically determined to be MCPM. To our knowledge, this is the first report of MCPM diagnosed and successfully treated by laparoscopic surgery during the course of follow-up for an ovarian tumor. It is important to recognize that MCPM can occur in patients who have previously undergone abdominal surgery, and laparoscopic surgery is recommended for patients of reproductive age, because of the potential risk of infertility associated with extensive pelvic surgery.

    In ovarian cancer cases, recurrence after chemotherapy is frequently observed, suggesting the involvement of ovarian cancer stem-like cells (CSCs). The chemoresistance of ovarian clear cell carcinomas is particularly strong in comparison to other epithelial ovarian cancer subtypes. We investigated the relationship between a CSC marker, aldehyde dehydrogenase 1 (ALDH1), and clinical prognosis using ovarian clear cell carcinoma tissue samples. Furthermore, we investigated the antioxidant mechanism by which CSCs maintain a lower reactive oxygen species (ROS) level, which provides protection from chemotherapeutic agents. Immunohistochemical staining was performed to examine the CSC markers (CD133, CD44, ALDH1) using ovarian clear cell carcinoma tissue samples (n=81). Clear cell carcinoma cell lines (KOC-7C, OVTOKO) are separated into the ALDH-high and ALDH-low populations by ALDEFLUOR assay and fluorescence-activated cell sorting (FACS). We compared the intracellular ROS level, mRNA level of the antioxidant enzymes and Nrf2 expression of the two populations. High ALDH1 expression levels are related to advanced stage in clear cell carcinoma cases. ALDH1 expression significantly reduced progression free survival. Other markers are not related to clinical stage and prognosis. ALDH-high cells contained a lower ROS level than ALDH-low cells. Antioxidant enzymes were upregulated in ALDH-high cells. ALDH-high cells showed increased expression of Nrf2, a key transcriptional factor of the antioxidant system. ALDH-positive CSCs might have increased Nrf2-induced antioxidant scavengers, which lower ROS level relevant to chemoresistance in ovarian clear cell carcinoma. Copyright © 2014 Elsevier Inc.

    This review was performed to describe the range of magnetic resonance imaging (MRI) appearances of borderline ovarian tumours. The MRI findings in 26 patients with 31 borderline ovarian tumours (mean age: 40.1 years, range: 14-85 years) were retrospectively reviewed. For each tumour, site, size, MRI characteristics, and enhancement following gadolinium administration were recorded. There were 20 serous and 11 mucinous borderline ovarian subtypes. Nine of 26 patients demonstrated bilateral disease on MRI; synchronous contralateral ovarian disease included three benign, five serous borderline, and one serous invasive tumour. A history of a metachronous mucinous borderline tumour was identified in one patient. MRI appearances were classified into four morphological categories: group 1 (6/31, 19%), unilocular cysts; group 2 (6/31, 19%), minimally septate cysts with papillary projections; group 3 (14/31, 45%), markedly septate lesions with plaque-like excrescences; and group 4 (5/31, 16%), predominantly solid with exophytic papillary projections, all of serous subtype. There was a significant difference in mean volume between serous (841.5 cm{sup 3}) and mucinous (6358.2 cm{sup 3}) subtypes (p = 0.009). All tumours demonstrated at least one MRI feature suggestive of malignancy. The present review demonstrates the variable MRI appearances of borderline ovarian tumours along with imaging features suggestive of tumour subtype. In patients in whom the clinical features are suggestive of a borderline ovarian tumour (young age and normal or minimally elevated CA125), the ability to predict a borderline disease using morphological features observed on MRI would be extremely helpful in surgical planning, with the potential to offer fertility or ovary-preserving surgery. Future studies are required to further this aim.

    CT was undertaken and CT numbers were measured in 47 patients with cystic ovarian lesions. CT features particularly for chocolate cyst revealed the uniform thickness of the whole cystic wall, findings suggesting adhesion to the surrounding organs, circular or oval shape, and higher CT numbers within the cyst than those in the other cystic ovarian lesions. However, because these features are not always observed in cases of chocolate cyst, one should not rely solely on CT findings in the diagnosis of chocolate cyst. (Namekawa, K.)

    As the worldwide incidence of cancer continuously rises, one of the measures to reduce mortality is early diagnosis while the disease is still curable. Colonoscopy screening and PAP-smears are worthwhile examples illustrating the impact of early diagnosis on mortality. Ovarian cancer is the first cause of mortality by gynecological cancers in Switzerland (incidence of 600 new cases / year), mostly diagnosed at advanced stages with a poor prognosis. Could surveillance measures improve survival ? Three large-scale randomized control trials failed to show mortality reduction from ovarian cancer with the methods currently available. A better comprehension of pathogenesis can allow the development of new strategies of screening.

    Epithelial ovarian cancer (EOC) is the most common cause of death among gynecological malignancies. Despite surgical and pharmacological efforts to improve patients' outcome, persistent and recurrent EOC remains an un-eradicable disease. Chimeric associated antigens (CAR) T cells are T lymphocytes expressing an engineered T cell receptor that activate the immune response after an MHC unrestricted recognition of specific antigens, including tumor associated antigens (TAAs). CART cells have been shown to be effective in the treatment of hematologic tumors even if frequently associated with potentially severe toxicity and high production costs. Areas covered: In this review, we will focus on preclinical and clinical studies evaluating CART activity in EOC in order to identify possible difficulties and advantages of their use in this particular setting. Expert Opinion: The pattern of diffusion within the peritoneal cavity, the tumor microenvironment and the high rate of TAAs make EOC a particularly interesting model for CART cells use. Data from preclinical studies indicate a potential activity of CARTs in EOC, but robust clinical data are still awaited. Further studies are needed to determine the best methods of administration and the most effective CAR type to treat EOC patients.

    Are live birth rates (LBR) different after ART cycles between women with primary or recurrent endometrioma? Women with recurrent endometrioma have similar LBR as compared to patients with primary endometrioma. Recurrence rate can be as high as 29% after endometrioma excision. Prior studies on management of endometrioma before ART involve primary endometriomas. There is limited information regarding the prognosis of women with recurrent endometriomas. A multicenter retrospective cohort study, including 76 women with primary and 82 women with recurrent endometriomas treated at the participating centers over a 6-year period. Women with endometrioma who underwent ART at three academic ART centers. Couples with another indication for ART were excluded. Female age, median number of prior failed ART cycles, proportion of patients with bilateral endometrioma (28 versus 28.9%), ovarian stimulation protocols, and total gonadotropin consumption were similar between the study groups. Numbers of metaphase two oocytes (5 versus 6), number of embryos transferred, and the proportion of patients undergoing blastocyst transfer were similar across the study groups. Clinical pregnancy rates (36.6 versus 34.2%, absolute difference 2.4%, 95% CI: -12.5 to 17.3%, P = 0.83) and LBR (35.4 versus 30.3%, absolute difference 5.1%, 95% CI: -9.5 to 19.7%, P = 0.51) per started cycle in recurrent and primary endometrioma were similar. Comparable success rates were also confirmed with logistic regression analysis (OR: 1.14, 95% CI: 0.78-0.57, P = 2.3). The retrospective design has inherent limitations. Some women with severely decreased ovarian reserve after primary endometrioma excision may not have pursued further treatment. The management of endometrioma prior to ART is controversial but a different management strategy is not required for recurrent endometriomas. Since recurrent endometriomas do not have a worse impact on ART outcome than primary endometriomas, and repeat surgery has a higher

    High-grade serous ovarian carcinoma (HGSOC) is the most frequent type of ovarian cancer and has a poor outcome. It has been proposed that fallopian tube cancers may be precursors of HGSOC but evolutionary evidence for this hypothesis has been limited. Here, we perform whole-exome sequence and copy number analyses of laser capture microdissected fallopian tube lesions (p53 signatures, serous tubal intraepithelial carcinomas (STICs), and fallopian tube carcinomas), ovarian cancers, and metastases from nine patients. The majority of tumor-specific alterations in ovarian cancers were present in STICs, including those affecting TP53, BRCA1, BRCA2 or PTEN. Evolutionary analyses reveal that p53 signatures and STICs are precursors of ovarian carcinoma and identify a window of 7 years between development of a STIC and initiation of ovarian carcinoma, with metastases following rapidly thereafter. Our results provide insights into the etiology of ovarian cancer and have implications for prevention, early detection and therapeutic intervention of this disease.

    Premature ovarian insufficiency (POI) is a major complication of cytotoxic treatments due to extreme ovarian sensitivity to chemotherapy and radiation. In pediatric cancer patients modern therapy has improved the long-term survival to over 80% in the United States. However, these cancer survivors face long-term health problems related to treatment toxicity. In female cancer survivors POI leads to sterility, along with the consequences of estrogen deficiency such as premature osteopenia, muscle wasting, accelerated cardiovascular diseases and a vast array of other health and developmental problems. These long-lasting effects are particularly significant for young girls reaching puberty. As such, restoring ovarian endocrine function is paramount in this population. In the present study, we evaluated the feasibility of restoring ovarian endocrine function in ovariectomized mice by transplanting syngeneic and allogeneic ovarian tissue encapsulated in alginate capsules or TheraCyte ® . Histological analysis of the implants retrieved after 7 and 30 days' post implantation showed follicular development up to the secondary and antral stages in both syngeneic and allogeneic implants. Implantation of syngeneic and allogeneic ovarian grafts encapsulated in TheraCyte devices restored ovarian endocrine function, which was confirmed by decreased serum FSH levels from 60 to 70 ng/mL in ovariectomized mice to 30-40 ng/mL 30 days after implantation. Absence of allo-MHC-specific IgG and IgM antibodies in the sera of implanted mice with allogeneic ovarian tissue encapsulated in TheraCyte indicate that the implants did not evoke an allo-immune response, while the allogeneic controls were rejected 21 days after implantation. Our results show that TheraCyte effectively isolates the graft from immune recognition but also supports follicular growth.

Common established causes include uterine anomalies, antiphospholipid syndrome, hormonal and metabolic disorders, and cytogenetic abnormalities. Other etiologies have been proposed but are still considered controversial, such as chronic endometritis, inherited thrombophilias, luteal phase deficiency, and high sperm DNA fragmentation levels. Over the years, evidence-based treatments such as surgical correction of uterine anomalies or aspirin and heparin for antiphospholipid syndrome have improved the outcomes for couples with recurrent pregnancy loss. However, almost half of the cases remain unexplained and are empirically treated using progesterone supplementation, anticoagulation, and/or immunomodulatory treatments. Regardless of the cause, the long-term prognosis of couples with recurrent pregnancy loss is good, and most eventually achieve a healthy live birth. However, multiple pregnancy losses can have a significant psychological toll on affected couples, and many efforts are being made to improve treatments and decrease the time needed to achieve a successful pregnancy. This article reviews the established and controversial etiologies, and the recommended therapeutic strategies, with a special focus on unexplained recurrent pregnancy losses and the empiric treatments used nowadays. It also discusses the current role of preimplantation genetic testing in the management of recurrent pregnancy

    Fab' fragments of the monoclonal antibody OV-TL 3, that recognizes an ovarian carcinoma-associated antigen (OA3), were labelled with 99 Tc m using D-glucarate as a ligand. Twenty patients suspected of having primary or recurrent ovarian cancer received intravenously 1 mg of the Fab' labelled with 740 MBq 99 Tc m . Both planar and single photon emission computed tomographic (SPECT) scintigraphy were performed up to 30 h after intravenous infusion. Imaging results were compared with X-ray computed tomography (CT), ultrasonography (US) and CA 125 serum level. Blood clearance was fast (t 1/2 of 9.5 h). Thirty-seven per cent of the injected dose (% ID) was excreted in the urine within the first 24 h, whereas 7% ID was excreted in the 24 h faeces. In one patient with an OA3 negative ovarian carcinoma, radioimmunoscintigraphy (RIS) did not visualize the tumour. In two other patients a benign ovarian cyst was found, also showing no elevated uptake. In 13 out of 17 patients ovarian cancer lesions were detected with RIS, whereas CT and US detected lesions in, respectively, 15 and 12 patients. Of 36 surgically defined tumour deposits larger than 1 cm in diameter, 53% were detected and localized with RIS, whereas CT and US detected 61 and 40%, respectively. Radioimmunoscintigraphy with 99 Tc m -OV-TL 3 Fab' is less distressing for the patients but the overall imaging performance is not improved when compared with 111 In-OV-TL 3 F(ab') 2 . (Author)

    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.

    The aim of the present systematic review was to study the effect of bipolar electrocoagulation during ovarian cystectomy on ovarian reserve. We searched Medline (1966-2015), Scopus (2004-2015), ClinicalTrials.gov (2008-2015), and Cochrane Central Register (CENTRAL) databases along with reference lists of electronically retrieved studies. The levels of antimullerian hormone (AMH) and antral follicle count (AFC) at 1, 3, 6, and 12 months following the excision of the benign ovarian cyst were defined as primary outcomes. Eight studies were finally included in our systematic review, which recruited 545 women. A metaanalysis was precluded because of significant heterogeneity in the methodological characteristics of the included studies. Data from the included studies suggest that the use of bipolar coagulation compared with ovarian sutures seems to result in significantly lower AMH and AFC during the first 3 months following the excision of the ovarian cyst. Two studies reported that this effect seems to persist at 6 and 12 months postoperatively. Bipolar electrodiathermy seems to be accompanied by increased damage to ovarian reserve, which is indicated by the lower levels of AMH and AFC. However, definitive results are precluded because of the significant heterogeneity of included studies and the potential bias. Copyright © 2015 Elsevier Inc. All rights reserved.

    Current treatment of ovarian cancer patients with chemotherapy leaves behind a residual tumor which results in recurrent ovarian cancer within a short time frame. We have previously demonstrated that a single short-term treatment of ovarian cancer cells with chemotherapy in vitro resulted in a cancer stem cell (CSC)-like enriched residual population which generated significantly greater tumor burden compared to the tumor burden generated by control untreated cells. In this report we looked at the mechanisms of the enrichment of CSC-like residual cells in response to paclitaxel treatment. The mechanism of survival of paclitaxel-treated residual cells at a growth inhibitory concentration of 50% (GI50) was determined on isolated tumor cells from the ascites of recurrent ovarian cancer patients and HEY ovarian cancer cell line by in vitro assays and in a mouse xenograft model. Treatment of isolated tumor cells from the ascites of ovarian cancer patients and HEY ovarian cancer cell line with paclitaxel resulted in a CSC-like residual population which coincided with the activation of Janus activated kinase 2 (JAK2) and signal transducer and activation of transcription 3 (STAT3) pathway in paclitaxel surviving cells. Both paclitaxel-induced JAK2/STAT3 activation and CSC-like characteristics were inhibited by a low dose JAK2-specific small molecule inhibitor CYT387 (1 μM) in vitro. Subsequent, in vivo transplantation of paclitaxel and CYT387-treated HEY cells in mice resulted in a significantly reduced tumor burden compared to that seen with paclitaxel only-treated transplanted cells. In vitro analysis of tumor xenografts at protein and mRNA levels demonstrated a loss of CSC-like markers and CA125 expression in paclitaxel and CYT387-treated cell-derived xenografts, compared to paclitaxel only-treated cell-derived xenografts. These results were consistent with significantly reduced activation of JAK2 and STAT3 in paclitaxel and CYT387-treated cell-derived xenografts

  10. VALPROATE, BIPOLAR DISORDER AND POLYCYSTIC OVARIAN SYNDROME.

    Science.gov (United States)

    Okanović, Milana; Zivanović, Olga

    2016-01-01

    Polycystic ovarian syndrome is a syndrome of ovarian dysfunction with the principal features of hyperandrogenism and polycystic ovary morphology. A large number of studies conducted on this topic have suggested a possible role of anticonvulsants, particularly valproate, in the pathogenesis or risk factors associated with polycystic ovarian syndrome. Bipolar treatment guidelines from Canada and the United States of America recommend valproate as the first line strategy in the acute treatment of bipolar disorder. Most persons with bipolar disorder require maintenance treatment. Long-term administration of valproate in women with bipolar disorder or epilepsy is believed to result in the increased risk of hyperandrogenism, menstrual abnormalities and polycystic ovaries. Valproate may also increase the risk of infertility and other associated symptoms of polycystic ovarian syndrome. Therefore, particular caution is indicated in the use of valproate in women of reproductive age. The treatment of the female patients with bipolar disorder presents various challenges for the clinician. Every woman of reproductive age needs to know the risk and benefits of her pharmacologic treatment options. Bipolar disorder should be considered chronic disorder, whose development is largely affected by hormonal changes and reproductive cycle in women. These issues should be researched more thoroughly in order to opt for the most appropriate treatment in women with bipolar disorder.

  11. Premature ovarian insufficiency: Pathogenesis and management

    Directory of Open Access Journals (Sweden)

    Anna J Fenton

    2015-01-01

    Full Text Available The term premature ovarian insufficiency (POI describes a continuum of declining ovarian function in a young woman, resulting in an earlier than average menopause. It is a term that reflects the variable nature of the condition and is substantially less emotive than the formerly used "premature ovarian failure" which signaled a single event in time. Contrary to the decline in the age of menarche seen over the last 3-4 decades there has been no similar change in the age of menopause. In developed nations, the average age for cessation of menstrual cycles is 50-52 years. The age is younger among women from developing nations. Much has been written about POI despite a lack of good data on the incidence of this condition. It is believed that 1% of women under the age of 40 years and 0.1% under the age of 30 years will develop POI. Research is increasingly providing information about the pathogenesis and treatments are being developed to better preserve ovarian function during cancer treatment and to improve fertility options. This narrative review summarizes the current literature to provide an approach to best practice management of POI.

    Puerperal ovarian vein thrombophlebitis(POVT) is a postpartum complication that requires prompt medical treatment to avoid extension of thrombus with potentially life-threatening complications. The prompt noninvasive diagnosing method is CT that defines the location and the extent about the thrombus. There findings will supply future case to be definitely diagnosed and treated without invasive procedures.

    The uterus and ovaries of 50 patients with polycystic ovarian disease (PCOD) and 30 eumenorrheic women were studied with a real-time ultrasound mechanical sector scanner. Uterine and ovarian volumes (UV and OV) and the OV/UV ratio were calculated, and ovarian morphology was classified as prevalently solid and cystic. Both ovaries were displayed in 44 of the PCOD and in 25 of the normal patients and appeared bilaterally solid, cystic, or with different morphology, respectively, in 43.2%, 47.7%, and 9.1% of cases in the former group and in 76%, 20%, and 4% in the latter group. Statistically significant differences between normal and PCOD patients were found in OV, UV, and OV/UV ratio. Bilaterally enlarged ovaries with multiple tiny cysts, the classic ultrasonographic picture of the polycystic ovary, were found in only 16 (36.3%) of the PCOD cases, while 34 (77.3%) had an OV/UV ratio greater than 1 standard deviation above the mean. Four ultrasonographic ovarian patterns were observed in the PCOD patients: enlarged cystic; enlarged solid; normal-sized cystic; and normal-sized solid. These findings emphasize the need for a reconsideration of the ultrasonographic criteria of PCOD.

    To evaluate MRI findings of malignant ovarian tumors. MRI findings were retrospectively reviewed in 25 patients with surgically confirmed 30 malignant ovarian tumors(common epithelial tumor; 23, sex cord stromal tumor; 2, endo dermal sinus tumor; 1, metastatic tumor; 4). The findings evaluated were the lesion size, solid and/or cystic component, wall thickness, septal thickness, necrosis, invasion of adjacent organ, ascites, and adenopathy. MRI findings of the malignant ovarian tumors were as follow: Size of lesion was 5-35cm(mean 14cm); solid component was present in 80%(24/30); wall thickness was more than 3mm in 90%(27/30); septal thickness was more than 3mm in 70%(21/30); tumor necrosis was present in 40%(12/30%); invasion of adjacent organ was present in 76%(19/25); ascites was present in 56%(14/25); lymphadenopathy was present in 24% (6/25). MRI findings of absence of solid component(6/6), even wall and septal thickness(7/7, 19/19) were found only in epithelial tumors. Uneven septal thickness more than 3mm(7/11) was a predominant MRI findings of non-epithelial tumors. Well-defined cystic lesion within solid component was seen in Krukenberg tumors. Evaluation of the lesion size, internal architecture, invasion of adjacent organ, ascites, and lymphadenopathy in MRI would enable diagnosis of malignant ovarian tumors and could lead to possible differential diagnosis of epithelial tumors from non-epithelial tumors

    To determine, through an analysis of radiologic findings, whether the findings of granulosa cell tumors (GCTs) of the ovary are specific. The radiologic findings (ultrasonography, computed tomography, and magnetic resonance imaging) of 16 pathologically proven ovarian GCTs in 15 patients were retrospectively analysed for the site of origin, staging, largest diameter, margin, solid and/or cystic components, degree of enhancement, and associated endometrial hyperplasia, ascites, and local and/or distant metastasis. Unilateral ovarian GCTs were found in 14 patients, and bilateral tumors in one. Of a total of 16 tumors, 13 were of the adult type, and three were juvenile; their largest diameter ranged from 1 to 26(mean, 15.6)cm. Eleven tumors were well-defined, two were cystic, and one small tumor was solid. Of 13 mixed tumors, three had hemorrhagic portions, and five had multilocular cystic portions. Metastases to the uterus, tubes, rectum, lymph nodes, or liver were found in six patients, and associated endometrial hyperplasia in two. Radiologically, ovarian GCTs showed well-defined or encapsulated soft tissue masses with some hemorrhagic, multilocular or focal cystic components, as well as associated endometrial thickening and local or distant metastasis. These and clinical findings may be useful in the diagnosis of ovarian GCTs.
