Guidelines for the treatment of tubo-ovarian cancer patients beyond third line are lacking. We aimed to evaluate the effect of response in each line on patient's outcome as well as identify variables that predict response for additional line of chemotherapy. A cohort study was performed including all patients with advanced high-grade ovarian cancer. Survival analysis was performed using Kaplan-Meier curves and log-rank tests. Odds ratios and hazard ratios were calculated using multilevel, mixed-effects logistic regression and Cox regression, adjusting for repeated measures within individual patients. Two-hundred thirty-eight patients were included and underwent up to 10 lines of chemotherapy. The median progression-free survival was 15.6 and overall survival (OS) was 55.6 months. Response rates dropped with each additional line and by line 5, most patients (61%) became refractory and only 16% had any type of response (complete 4% or partial 12%). By line 2, whether a patient had partial disease (PR), stable disease (SD) or progressive disease (PD) did not have an effect on the OS. From line 2, whether a patient had PR, SD or PD did not have an effect on chemotherapy-free interval. Number of previous lines and time from previous line were the only variables that significantly correlated with both outcome of patients and response to the next line. In conclusion, time interval from the previous line of chemotherapy is the major clinical factor that predicts beneficial effect of another line of treatment in patients with ovarian cancer.

Background Conventional first-line combination therapy for ovarian cancer comprises 6 cycles of adjuvant or neoadjuvant carboplatin (AUC5-6) with paclitaxel (175 mg/m2) every 3 weeks (PC-3W). Weekly scheduling of paclitaxel may maximize its antiangiogenic effect and reduce adverse effects. We compared the efficacy and safety of PC-3W with a modified protocol of weekly paclitaxel 80 mg/m2 and weekly carboplatin AUC2 administered on days 1, 8, and 15 in a 28-day cycle (i.e., with 1 week off-treatment [PC-W]). Materials and Methods Medical records of consecutive patients treated between 2000 and 2018 were reviewed; 707 patients were analyzed for demographic and clinical characteristics, effectiveness and toxicity. Results PC-3W was administered to 402 patients (median age, 60.5 years) and PC-W to 305 patients (median age, 62.5 years). Most patients (91.4%) were diagnosed at stage III–IV. Notwithstanding a higher proportion of residual disease and older patients in the PC-W group, median progression-free survival was 21.4 months and 13.2 months for PC-W and PC-3W, respectively; median overall survival was 75.2 and 54.0 months for PC-W and PC-3W, respectively. Cox proportional hazards model indicated improved survival for patients treated with PC-W (hazard ratio, 0.54). Similar results were observed for older patients diagnosed at ≥75 years. PC-W demonstrated a better safety profile, with lower incidence of neuropathy, neutropenia, and alopecia. Conclusion PC-W is as active and better tolerated than the standard PC-3W regimen. PC-W may serve as an alternative option for elderly or frail patients. Implications for Practice Weekly scheduling of paclitaxel 80 mg/m2 and carboplatin AUC2, administered on days 1, 8, and 15 in a 28-day cycle (PC-W) for first-line therapy for advanced ovarian cancer, is as active and better tolerated than the standard regimen of carboplatin and paclitaxel (175 mg/m2) every 3 weeks (PC-3W). It is possible that the weekly holiday on day 21 in the PC-W regimen may ensure better completion rates (which may result in treatment delays for toxicity in PC-3W). The results of this retrospective analysis highlight the weekly regimen as a valid treatment option, especially for elderly patients and those with significant comorbidities.

Highlights • Patients suffering from both breast and endometrial cancer seem to have unique characteristics. • The sequence of occurrence of malignancies appears to have significance. • In patients that endometrial cancer was diagnosed as a second tumor, it tended to present in a more aggressive form. • In this group, a longer time interval between diagnoses might offer diagnostic and prophylactic opportunities. • No correlation was found to tamoxifen usage among patients., Objective To examine whether patients with both breast cancer (BC) and endometrial cancer (EC) have different features of disease, and whether the sequence of appearance of these tumors is correlated with a more aggressive course. Methods A retrospective, multi-center observational cohort study of patients treated in two tertiary medical centers between 2014 and 2020. Files of patients who had a co-diagnosis of BC and EC were reviewed and clinical, epidemiological, pathological and genetic characteristics were collected. Results 67 patients with a co-diagnosis of both malignances were divided into two groups according to primary tumor diagnosis: BC first group (43/67, 64%) and EC first group (24/67, 36%). The time interval between diagnosis of malignancies was significantly longer in the BC first group (mean 144.5 months vs. 67 months, p

Objective To evaluate the accuracy of ascites cytology in the diagnosis of epithelial ovarian cancer among postmenopausal women. Methods Ascites samples of women older than 51 years sent for cytology evaluation at our institution between 2010 and 2015 were retrospectively compared to final histology. The sensitivity, specificity, negative, and positive predictive values were calculated. Immunohistochemistry stain results were collected to determine diagnostic profiles. Results A total of 551 patients, 51 years and over had both cytology and diagnostic histology samples. Of those, 161 patients had pathology confirmed ovarian tumors, 155 of which were malignant. Of the 155 cases of ovarian cancer, 125 patients had malignant cells on cytology examination (true positive); in 30 cases, ascites was negative for malignancy (false negative). In six cases both ascites and final pathology were negative for malignancy (true negative). There were no cases of positive cytology and negative final pathology (ie, no false-positive cases). The sensitivity, specificity, positive, and negative predictive value for cytology diagnosis of ovarian cancer were 80.6%, 100%, 100%, and 16.7%, respectively. Immunohistochemistry was done on cell blocks in 79 cases of ovarian cancer, 75 (94.9%) had profiles diagnostic for ovarian origin. Conclusions Ascites cytology for postmenopausal women older than 51 years with immunohistochemistry is highly accurate in diagnosis of ovarian cancer. Neoadjuvant chemotherapy can be safely prescribed based on paracentesis evaluations. : Video Summary:http://links.lww.com/MENO/A570.

Introduction The objective was to assess whether an early response to neoadjuvant chemotherapy in women with advanced ovarian cancer may predict short- and long-term clinical outcome. Material and methods This is a retrospective study of all women with stage III-IV tubo-ovarian cancer treated with neoadjuvant chemotherapy at a single center in Montreal between 2003 and 2014. Logistic regression models were used to evaluate the association between cancer antigen 125 (CA-125) levels during neoadjuvant chemotherapy and debulking success. Cox proportional hazard models were used to estimate hazard ratios and their respective 95% CI for death and recurrence. Harrell's concordance indices were calculated to evaluate which variables best predicted the chemotherapy-free interval and overall survival in our population. Results In all, 105 women were included. Following the first, second, and third cycles of neoadjuvant chemotherapy, CA-125 levels had a median reduction of 43.2%, 85.4%, and 92.9%, respectively, compared with CA-125 levels at diagnosis. As early as the second cycle, CA-125 was associated with overall survival (hazard ratio 1.03, 95% CI 1.01-1.05, per 50 U/mL increment). By the third cycle, CA-125 did not only predict overall survival (hazard ratio 1.04, 95% CI 1.01-1.08), but it predicted overall survival better than the success of debulking surgery (Harrell's concordance index 0.646 vs 0.616). Both absolute CA-125 levels and relative reduction in CA-125 levels after 2 and 3 cycles predicted the chance to achieve complete debulking (P Conclusions Reduction of CA-125 levels during neoadjuvant chemotherapy provides an early predictive tool that strongly correlates with successful cytoreductive surgery and long-term clinical outcome in women with advanced high-grade serous and endometrioid ovarian cancer.

PurposeTo evaluate the use of an intrauterine manipulator on the oncologic outcome of women who had minimally invasive surgery for endometrial cancer. MethodsRetrospective analysis of consecutive patients who were operated with or without the use of an intrauterine manipulator. Univariate and multivariate analysis were used to adjust for possible confounders. Results699 patients were included, of whom 220 (32.8%) were operated with an intrauterine manipulator. The median follow-up was 44 months (range, 29-67). Disease-free survival was similar between groups. 19 (8.8%) patients had positive cytology in the manipulator group vs. 21 (4.4%) in the comparison group (p=0.02). Total recurrence rate was similar between the groups (12.3% vs. 11.9%; p = 0.8). Vaginal vault recurrence was the most common site of recurrence with higher incidence in the manipulator group (4.5% vs. 1.3%; p=0.007). Sub-group analysis of patients who did not receive adjuvant treatment showed higher recurrence rate (8.3% vs. 3%; p=0.023) and worse disease-free survival (p=0.01) for the manipulator group. After controlling for other variables, the use of a manipulator did not affect the risk of recurrence for the whole cohort (HR, 1.28; 95% CI, 0.7-2.1, p=0.3) and for the sub-group of patients who did not receive adjuvant treatment (HR, 2.47; 95% CI, 0.8-7, p=0.08).ConclusionThe use of a manipulator during surgery for endometrial cancer increases the risk of positive cytology as well as vaginal vault recurrences, but it does not reduce the disease-free and overall survival of patients.

Background Gynecologic oncologists should be aware of the option of conception through IVF/PGT-M for families with high BRCA related morbidity or mortality. Our objective was to investigate the cost-effectiveness of preimplantation genetic testing for selection and transfer of BRCA negative embryo in BRCA mutation carriers compared to natural conception. Methods Cost-effectiveness of two strategies, conception through IVF/PGT-M and BRCA negative embryo transfer versus natural conception with a 50% chance of BRCA positive newborn for BRCA mutation carriers was compared using a Markovian process decision analysis model. Costs of the two strategies were compared using quality adjusted life years (QALYs’). All costs were discounted at 3%. Incremental cost effectiveness ratio (ICER) compared to willingness to pay threshold was used for cost-effectiveness analysis. Results IVF/ PGT-M is cost-effective with an ICER of 150,219 new Israeli Shekels, per QALY gained (equivalent to 44,480 USD), at a 3% discount rate. Conclusions IVF/ PGT-M and BRCA negative embryo transfer compared to natural conception among BRCA positive parents is cost effective and may be offered for selected couples with high BRCA mutation related morbidity or mortality. Our results could impact decisions regarding conception among BRCA positive couples and health care providers.

INTRODUCTION We compared oncologic and clinical outcomes in patients with advanced ovarian cancer who received dose-dense weekly paclitaxel with 3-weekly carboplatin with those who received standard 3-weekly chemotherapy. MATERIAL AND METHODS Comparison of all consecutive patients with advanced (International Federation of Gynecology and Obstetrics stages III-IV) ovarian cancer who received a dose-dense protocol between 2010 and 2016 with an immediate historical cohort of consecutive patients who received standard chemotherapy. Patients who received less than three cycles of treatment were excluded. RESULTS In all, 246 patients were included in the study, of whom 128 received the dose-dense protocol and 118 were treated with the standard Q3-week protocol. Patients in the dose-dense group had significantly better progression-free survival than those receiving the standard protocol (median progression-free survival 22 vs 15 months; log rank = 0.026). The overall survival of patients in the dose-dense group was also better than that of the patients in the standard protocol group; however, this difference was not statistically significant (median overall survival 66 vs 54 months; log rank = 0.185). The dose-dense protocol remained significantly associated with favorable survival outcome in multivariable analysis adjusted for stage, histologic type, cytoreductive results and neoadjuvant chemotherapy. The use of the dose-dense protocol was associated with higher rates of gastrointestinal, dermatologic, neurologic and hematologic side effects. CONCLUSION Despite the limitations associated with the comparison to a historical cohort, a dose-dense chemotherapy protocol resulted in a significantly improved progression-free survival and the overall survival tended to be better, but this difference did not reach statistical significance compared with the standard chemotherapy protocol, and may be considered as a treatment alternative, albeit with some increased side effects.

Study Objective To assess the effect of carbon dioxide (CO2) pneumoperitoneum and steep Trendelenburg position on patients’ cardiac function and hemodynamics during minimally invasive staging surgery for endometrial cancer. Design Single-center prospective longitudinal study. Setting University-affiliated tertiary hospital. Patients Patients with endometrial cancer undergoing minimally invasive surgery. Interventions After consent, the patients’ hemodynamic parameters were assessed by the Non-Invasive Cardiac System (NI Medical, Petah Tikva, Israel) at 5 time points: before general anesthesia, after induction of general anesthesia, after CO2 insufflation of the peritoneum, after steep Trendelenburg position, and at the end of surgery. Measurements and Main Results Twenty-three women were recruited. The median age of the patients was 68 years (interquartile range [IQR] 62–75), with a median body mass index of 34.9 kg/m2 (IQR 31.2–39.5) and an American Society of Anesthesiologists score ≥2. The initial median mean arterial pressure was 108 mmHg (IQR 101–113), and the baseline median cardiac output was 7.2 L/min (IQR 5.6–8.7). The median mean arterial pressure significantly decreased by 18% after insufflation (p = .001), again after Trendelenburg position (p = .003), and did not fully recover at the end of surgery in comparison with the preanesthesia baseline (p = .001). The median stroke volume significantly decreased by 17% after insufflation compared with the baseline (p = .01) and then gradually recovered to the baseline levels by the end of surgery. The median cardiac power significantly decreased by 35% after insufflation (0.009), remained low during Trendelenburg position (p = .009), and recovered by the end of surgery to 18% below the baseline levels (p = .035). Conclusion Significant hemodynamic changes occur during minimally invasive staging surgery for endometrial cancer. CO2 insufflation is accompanied by the most dramatic hemodynamic deterioration during surgery, and this does not get affected much with Trendelenburg. Knowledge of the hemodynamic values of women classified as high risk when using a noninvasive technique during surgery is obtainable and may assist both surgeon and anesthesiologist to ensure a safer procedure.

With the growing technical ease and reduction in genetic screening costs, whole population BRCA screening may be a feasible option. Our objective was to investigate the cost effectiveness of whole population screening for BRCA mutations in Israel, for varying degrees of BRCA carrier state. Lifetime costs of whole female population screening for BRCA mutation carrier state versus nonscreening were compared using a Markovian process decision analysis model. Model parameters including ovarian and breast cancer risks were obtained from previously published data. Screening and other treatment-related costs were received from the Israeli Ministry of Health pricing list according to specified codes. Quality-adjusted life years were used for cost-effectiveness analysis. Sensitivity analysis was conducted to evaluate model uncertainties, specifically varying degrees of BRCA prevalence. Results show that whole population BRCA screening in Israel is cost effective across a wide range of BRCA prevalence rates with an incremental cost-effectiveness ratio of 81,493 new Israeli Shekels for a BRCA prevalence of 2.5%, increasing to 250,000 new Israeli Shekels for a 0.75% prevalence rate, per quality-adjusted life year gained. Discount rate and population BRCA prevalence and rate of risk reduction salpingo-oophorectomy are the most influential parameters in the model. Whole population screening for BRCA mutations should be offered as part of general health screening strategies by national medical insurance providers, even for non-Ashkenazi Jews. Our algorithm can be applied for other countries, adjusting local costs of screening and treatment. Prevention Relevance: Whole population BRCA mutation screening in Israel is cost effective across a wide prevalence rate and should be offered as part of general health screening strategies by national medical insurance providers for cancer prevention.

Objective To propose a treatment algorithm, after the LACC trial, of laparoscopic sentinel lymph node biopsy with frozen section, followed by immediate open radical hysterectomy in node-negative cases, for early stage cervical cancer. Methods We retrospectively collected all cases of cervical cancer that were surgically treated in 2019-2020. In all cases, surgery began with laparoscopic sentinel lymph node biopsy ± ovarian transposition. Node-negative cases continued with open radical hysterectomy. In node-positive cases, surgery was discontinued, sparing the patient a laparotomy incision. Results Nine patients with cervical cancer were referred for surgery. Laparoscopic bilateral lymph node identification was achieved in all. In two cases, sentinel lymph nodes were positive for metastatic cancer and surgery was discontinued. For the other seven, node-negative patients, open radical hysterectomy was completed. Four patients had laparoscopic ovarian transposition. There were no cases where nodes were negative on frozen section but positive on final pathology. Conclusion Laparoscopic sentinel lymph node biopsy before open radical hysterectomy may spare a considerable number of laparotomies on the one hand and bi-modal treatment with surgery and radiation on the other, for node-positive patients. The oncological safety of this approach is yet to be determined.

Objective This study sought to evaluate the incidence, risk factors, and estimated cost associated with venous thromboembolism (VTE) following robotic surgery for endometrial cancer. Methods The study included all consecutive patients with newly diagnosed endometrial cancer who underwent robotic surgery, excluding patients with a previous history of VTE (3%), those taking long-term warfarin (3%), and patients with conversions to laparotomy (3%). The incidence of postoperative symptomatic VTE within 90 days was analyzed. Direct and indirect medical costs were estimated using a linked billing database for standardized, inflation-adjusted costs. Results A total of 558 cases were identified. Median BMI was 29 kg/m2 (range, 17–85 kg/m2), median operative time was 227 minutes (range, 75–419 minutes), and median blood loss was 30 mL (range, 3–400 mL). All patients received thromboprophylaxis with intraoperative subcutaneous heparin and sequential pneumatic compression devices. Extended postoperative prophylaxis for 28 days was administered to 88 (17.2%) patients with high-risk factors. A total of eight patients (1.6%) developed symptomatic VTE, and all eight were in the group that did not receive extended prophylaxis. The number needed to treat to prevent one VTE was 52.8, with an absolute risk reduction 1.89% (95% CI 0.59% to 3.19%). The average cost for treatment of a VTE was $7653 (range, $4396–$12 211), equivalent to the cost of treating 21 patients with extended prophylaxis ($356 per patient). Conclusion The incidence of VTE in patients with endometrial cancer who underwent robotic-assisted surgery was low (1.6%), and none of the VTEs occurred in the cohort of high-risk patients who received extended thromboprophylaxis.

Objective: Evaluation of the impact of lower uterine segment involvement (LUSI) in type II endometrial cancer, and mutational profile of uterine papillary serous carcinomas (UPSC). Methods: Retrospective cohort study comparing patients with type II endometrial cancer with LUSI to patients without LUSI. Genes commonly implicated in carcinogenesis were analyzed in a subgroup of 42 patients with UPSC using next generation sequencing. Results: 83 patients with type II endometrial cancer were included in the study, of these, LUSI was diagnosed in 31.3%. During a median follow-up of 45.5 months, patients with LUSI developed more local and distant recurrences (local: 19.2% vs. 3.5%, P = .03; distant: 50% vs. 17.5%, P = .004) and progression events (73.1% vs. 26.3%, P

Objectives: Although non-inferior overall survival and reduced surgical morbidity with neoadjuvant therapy (NAC) compared to primary debulking surgery, upfront debulking surgery remains the treatment of choice for newly diagnosed advanced stage ovarian cancer (OC) in the US. This can be partially attributed to the association of aggressive surgical treatment with long term survival (LTS) demonstrated in high grade serous OC (HGSOC). On the contrary, NAC has been shown to lower the odds for LTS. We aimed to identify clinico-pathologic factors associated with LTS in advanced epithelial OC (EOC) treated with NAC. Methods: This is a retrospective case-control study. Women with FIGO stage III-IV high grade epithelial cancer of the ovary, fallopian tube or peritoneum diagnosed and treated with NAC prior to 2013 were extracted from consecutive patient records of the Tel-Aviv Sourasky Medical Center. Women surviving longer than 7 years from diagnosis (defined as long-term survivors, LTS) were compared to women surviving 6-24 months from diagnosis (defined as short-term survivors, STS). Patients with low grade or low malignant potential tumors were excluded. Results: We identified 190 women with stage III/IV epithelial OC. Seventy-eight patients (41%) survived longer than 5 years from diagnosis and 47 (24%) survived longer than 7 years from diagnosis, significantly higher proportions compared to previous reports. Thirty-nine patients (20%) survived 6-24 months, similar to previous reports. Clinicopathologic and treatment characteristics of both groups are displayed in Table 1. CA125 pre-treatment or after 4 courses of chemotherapy and the number of adjuvant and total chemotherapy courses administered were similar between the groups. LTS were significantly younger than STS at diagnosis, with a mean age of 60.05 years vs 65.95 years, respectively (p=0.008). The majority of LTS received 3 courses of NAC or less compared to STS (59.6% vs 33.4%), implying a smaller disease burden or better response to NAC. LTS had a significantly longer disease-free interval (80.49 months vs 3.65 months, p Download : Download high-res image (404KB) Download : Download full-size image Conclusions: Our analysis, to the best of our knowledge, is the first to demonstrate that NAC does not compromise the odds of long-term survivorship in women with advanced EOC, further strengthening NAC as an equivalent alternative to primary debulking surgery. In addition, we identified basic clinicpathologic and treatment-related factors associated with long term survival of epithelial OC patients treated with NAC. Further investigation is needed to determine which factors should be integrated into treatment-related decisions.

Objective The expression of homologous recombination (HR) genes in high grade ovarian cancer (HGOC) samples from debulking surgeries were correlated to outcomes in patients selected for chemotherapy treatment regimens. Study design RNA was extracted from 96 fresh frozen tumor samples from debulking surgeries from chemotherapy naive patients with HGOC (primary derived surgeries (PDS), n = 55) or following neoadjuvant chemotherapy treatment (NACT), n = 41). The samples were selected for high tumor content by a gynecological pathologist, and cancer cell content was further confirmed using a percent tumor content covariate, and mutation score covariate analysis. Gene expression analysis was performed using a tailored NanoString-based Pancancer Pathway Panel. Cox proportional hazard regression models were used to assess the associations between the expression of 19 HR genes and survival. Results In the PDS group, over-expression of six HR genes (C11orf30, NBN, FANCF, FANCC, FANCB, RAD50) was associated with improved outcome, in contrast to the NACT group where four HR genes (BRCA2, TP53, FANCB, RAD51) were associated with worse outcome. With the adding extent of debulking as a covariate, three HR genes (NBN, FANCF, RAD50), and only one HR gene (RAD51) remained significantly associated with survival in PDS and NACT groups, respectively. Conclusion Distinct HR expression profiles define subgroups associated with overall outcome in patients that are exposed to neoadjuvant chemotherapy and not only chemotherapy-naive patients.

Objective Pilot study to assess the value of weekly paclitaxel plus carboplatin every 3weeks (dose dense regimen, DD) compared to the standard 3-weekly protocol in the adjuvant setting for endometrial cancer. Methods Retrospective cohort study comparing consecutive patients with high and intermediate-high risk endometrial cancer, undergoing DD protocol (from 2011 to 2015) to a non-overlapping historical cohort with similar characteristics who received treatment every three weeks (2008–2011). Results 122 patients with endometrial cancer were included in the study, of these, 61 patients received the dose dense protocol and 61 were treated with the standard 3-weekly protocol. After a median follow-up of 61.6months in the 3-weekly cohort, compared with 41.6months in the DD cohort, 40 progressions were recorded. 29 progressions were observed in women treated in the standard protocol, with a three years progression free survival (PFS) of 57.4%, compared to 11 progressions observed in patients in the DD schedule, with a three years PFS of 79.5% ( P =0.03). Patients who were treated with the DD protocol were less likely to have progression events compared to the standard cohort with a hazard ratio of 0.4 on multivariate analysis (CI 95%, 0.2–0.8, P =0.01), had significantly less distant metastases ( P =0.01), and had improved overall survival when diagnosed with advanced stage disease ( P =0.02). Complaints of musculoskeletal pain were more frequent in the standard cohort ( n =17, 27.9%) compared to the dose dense cohort ( n =4, 6.6%), P =0.005. Conclusion Preliminary data suggests that dose dense chemotherapy might be a reasonable and superior option for adjuvant treatment of endometrial cancer, compared to standard chemotherapy.

Objective To compare short-term fertility rates after medical and surgical management of early miscarriage. Design Observational cohort study. Setting Academic tertiary-care medical center. Patient(s) A total of 203 patients were enrolled between June 2017 and May 2018, comprising 106 surgical evacuations and 97 medical evacuations. Intervention(s) Either surgical or medical evacuation of the uterine cavity. Main Outcome Measure(s) Conception rates 6 months after miscarriage. Result(s) Conception rates 6 months after miscarriage among women who had attempted to become pregnant were similar between the medically and surgically evacuated groups (68.0% vs. 65.1%). There were no significant differences in background characteristics between the groups, apart from younger age and earlier gestational age among the medically treated group. There was no difference in the proportion of women using assisted reproductive technologies between the medically and surgically managed groups (15.5% vs. 12.6%, respectively). The median time-to-conception was 4 ± 2 months in both groups. Cumulative pregnancy rate 12 months after pregnancy loss, live birth rate, and repeat miscarriage rate also were similar between groups. Conclusion(s) Modality of uterine evacuation after early miscarriage does not affect short-term fertility outcomes.

Objective To evaluate the impact of surgical wait times on outcome of patients with grade 3 endometrial cancer. Methods All consecutive patients surgically treated for grade 3 endometrial cancer between 2007 and 2015 were included. Patients were divided into two groups based on the time interval between endometrial biopsy and surgery: wait time from biopsy to surgery ≤12 weeks (84 days) vs more than 12 weeks. Survival analyses were conducted using log-rank tests and Cox proportional hazards models. Results A total of 136 patients with grade 3 endometrial cancer were followed for a median of 5.6 years. Fifty-one women (37.5%) waited more than 12 weeks for surgery. Prolonged surgical wait times were not associated with advanced stage at surgery, positive lymph nodes, increased lymphovascular space invasion, and tumor size (P = .8, P = 1.0, P = .2, P = .9, respectively). In multivariable analysis adjusted for clinical and pathological factors, wait times did not significantly affect disease-specific survival (adjusted hazard ratio [HR]: 1.2, 95% confidence interval [CI], 0.6-2.5, P = .6), overall survival (HR: 1.1, 95% CI, 0.6-2.1, P = .7), or progression-free survival (HR: 0.9, 95% CI, 0.5-1.7, P = .8). Conclusion Prolonged surgical wait time for poorly differentiated endometrial cancer seemed to have a limited impact on clinical outcomes compared to biological factors.

Objective To perform a hypothesis-generating evaluation of patient outcomes following neoadjuvant chemotherapy (NACT) compared with those following primary debulking surgery (PDS) in patients over age 75 with high-grade ovarian cancer. Methods This was a retrospective cohort study of consecutive patients aged 75 years and older, with high-grade ovarian cancer. Data were analyzed in SPSS 25.0 using descriptive statistics to characterize groups based on primary treatment modality, Kaplan-Meier survival curves to estimate overall and progression-free survival, and Cox proportional hazards to analyze confounders. Results Of 429 patients with stages III and IV high-grade ovarian cancer (endometrioid and serous), 71 were aged older than 75 years and met our criteria for inclusion; 58 were treated with NACT while 13 underwent primary debulking. Sixteen patients did not undergo interval debulking following NACT. There were no significant differences in demographic characteristics between the groups. Following NACT, more patients were completely debulked—36.2% versus 21% (P = 0.000)—and had a shorter length of stay (5 vs. 7 d; P = 0.018). Overall survival was similar between the NACT and PDS groups (58.7 vs. 59.7 mo; LR –0.836; P = 0.361) despite lower progression-free survival in the NACT group (25.9 vs. 47.1 mo; P = 0.042; LR 4.31). Both progression-free and overall survival were significantly higher when patients undergoing NACT achieved complete debulking (21.7 and 102.3 mo, respectively) compared with suboptimal debulking (12.03 and 14.2 mo, respectively). Conclusion In this select group older patients with stage III and IV high-grade ovarian cancers, neoadjuvant chemotherapy may be considered without compromising outcomes and contributes to complete debulking.

Highlights • Preoperative diagnosis of endometrioid carcinoma is common in finally diagnosed serous endometrial cancer. • Endometrioid preoperative sample is associated with better outcome in women finally diagnosed with serous uterine cancer. • Endometrioid preoperative sample is reflected in the mutational profile of final pathology., The aim of this study was to evaluate the impact of discordant endometrial sampling on the prognosis of patients finally diagnosed with uterine papillary serous carcinoma (UPSC) and to analyze UPSC mutational profile. Retrospective cohort study comparing outcomes of patients post-operatively diagnosed with UPSC and preoperatively diagnosed with endometrioid endometrial cancer (EEC) or UPSC. Genes commonly implicated in carcinogenesis were analyzed in a subgroup of 40 patients post-operatively diagnosed with UPSC, using next generation sequencing. 61 patients with UPSC on post-surgical, final pathology were included in the study. Prior to surgery, 15 were diagnosed with EEC (discordant) and 46 were correctly diagnosed with UPSC (concordant). After a median follow-up of 41.6 months [5.4–106.7], a preoperative diagnosis of EEC was associated with better 3-year progression-free survival (100% vs. 60.9%, P = 0.003) and longer disease free interval (63.5 versus 15 months, P = 0.026) compared to patients with an initial diagnosis of UPSC. Patients with a concordant diagnosis of UPSC were 5 times more likely to progress or die compared to those with a discordant EEC diagnosis (P = 0.02, P = 0.03, respectively), and their tumors were associated with higher rates of TP53 (88.9% vs. 61.5%, P = 0.04), and a lower rate of PTEN (14.8% vs. 38.5%, P = 0.09) and ARID1A (3.7% vs. 23.1%, P = 0.05) mutations. A pre-surgical diagnosis of EEC is associated with improved prognosis in patients with UPSC. Some histologically defined UPSC tumors contain endometrioid-like molecular characteristics that may confer a survival advantage, suggesting a possible need for molecular approaches to better stratify patients into risk groups.

Introduction/Background Patients over 75 with high grade ovarian cancer have poorer prognosis compared to younger patients due to decreased physiologic reserves, delayed diagnosis, and undertreatment due to fear of toxicity. We performed a hypothesis generating evaluation of outcomes following neoadjuvant chemotherapy compared to primary debulking surgery in patients over 75 with high grade ovarian cancer. Methodology This is a retrospective cohort study of consecutive patients 75 years and above, with high grade stage III-IV ovarian cancer. Patients with inadequate follow-up were excluded. Descriptive statistics were performed to characterize groups based on primary treatment modality. Kaplan Meier survival curves were used to estimate overall and progression free survival with log rank tests for significance. Cox proportional hazards was performed for analysis of confounders. Results Among 429 patients with stages III-IV high grade ovarian cancer (endometrioid and serous), 55 were over 75 years old and met inclusion criteria; 42 were treated with neoadjuvant chemotherapy followed by interval debulking compared to 13 patients undergoing primary debulking. There was no significant difference in demographic parameters. More patients were optimally debulked following neoadjuvant chemotherapy (50% vs 23%, p=0.003) and had a shorter length of stay (5 vs 7 days, p=0.018). Overall survival (mean 67.3 vs 59.7 months, p=0.765), and progression free survival (31.1 vs 47.1 months, p=0.143) were similar in patients treated with neoadjuvant chemotherapy compared to primary debulking. Conclusion In this limited number of older patients with Stage III-IV high grade ovarian cancers, there was no significant difference in survival between those treated with neoadjuvant chemotherapy and primary debulking surgery.

Ovarian cancer is the most lethal gynecological malignancy. Currently, new chemotherapeutic strategies are required to improve patient outcome and survival. Biguanides, classic anti‐diabetic drugs, have gained importance for theiri antitumor potency demonstrated by various studies. Olaparib is a PARP inhibitor approved for maintenance therapy following platinum‐based chemotherapy. Furthermore, Snai1, a transcription factor that works as a master regulator of the epithelial/mesenchymal transition process (EMT) is involved in ovarian cancer resistance and progression. Here we aimed to demonstrate the possible cross talk between biguanides and Snail in response to olaparib combination therapy. In this study, we have shown that while in A2780CR cells biguanides reduced cell survival (single treatments ~20%; combined treatment ~44%) and cell migration (single treatments ~45%; biguanide‐olaparib ~80%) significantly, A2780PAR exhibited superior efficacy with single (~60%) and combined treatments (~80%). Moreover, our results indicate that knock‐down of Snail further enhances the attenuation of migration, inhibits EMT related‐proteins (~90%) and induces a synergistic effect in biguanide‐olaparib treatment. Altogether, this work suggests a novel treatment strategy against drug‐resistant or recurrent ovarian cancer., Biguanides in combination with PARP inhibitors synergistically reduce EMT, proliferation and survival of ovarian drug‐resistant cancer cells.

The CD24 gene has raised considerable interest in tumor biology as a new prognostic factor and a biomarker for the early detection of cancer. There are currently no studies that assess predictors of CD24 in blood tests among healthy individuals. Our aims were (1) to evaluate predictors of the CD24/CD11b biomarker among healthy subjects and (2) to assess CD24/CD11b levels of participants with and without benign tumors. Our cohort included 1640 healthy subjects, aged 20–85, recruited at the Health Promotion and Integrated Cancer Prevention Center (ICPC) in the Tel Aviv Medical Center. Eligible subjects completed a detailed questionnaire on medical history and other epidemiologic information. CD24/CD11b expression in peripheral blood leukocytes (PBLs) obtained from blood samples of participants was analyzed by flow cytometry. Our results showed that the average levels of CD24/CD11b in healthy patients (22.8 ± 9.3) was statistically significant lower compared to subjects with benign cancers (26.1 ± 10.5, p &lt, 0.001). Our multivariable analysis demonstrated that elevated levels of CRP (coefficient β: 1.98, p = 0.011) were significantly associated with high levels of CD24/CD11b expression among healthy participants. Other risk factors of cancer were not associated with elevated CD24 levels among healthy subjects. In conclusion, our findings may assist in further development and optimization of the CD24/CD11b biomarker to serve as a cancer screening test for early detection of cancer among the healthy population.

Objective To evaluate clinical outcome in patients selected to receive neoadjuvant chemotherapy (NACT) compared to primary debulking surgery (PDS). Methods Retrospective study including all consecutive patients diagnosed and treated for advanced (stages III-IV) ovarian cancers between the years 2003–2015. Results 263 women were included in the study, of these, 127 patients were selected to receive NACT and 136 were treated with PDS followed by adjuvant chemotherapy. PDS was associated with longer OS in stage IIIc disease (median OS: 60.2 vs. 48.8months; p -value 0.039) compared with NACT. Patients achieved higher rates of complete cytoreduction in the NACT group compared to the PDS group (65.9% vs. 40.2%; p =0.001). Patients attaining complete cytoreduction after PDS had the best survival, (median OS 106months) followed by those with complete cytoreduction after NACT (median OS 71months), followed by those with residual disease after PDS (median OS 55months). Patients with residual disease following interval debulking after NACT had the worst outcome (median OS 36months). Platinum sensitivity following first line and second line chemotherapy was similar whether patients received neoadjuvant chemotherapy or not. Conclusion PDS was associated with improved outcome. NACT appears to improve survival outcome in patients that would have had residual disease after PDS, and attain complete cytoreduction at the time of interval cytoreduction. This treatment option can be used in selected patients that are not candidates for complete cytoreduction at PDS.

PurposeEpithelial-mesenchymal transition (EMT) is a critical process for cancer metastasis and recurrence. Metformin, an effective oral antidiabetic drug, has been associated with decreased cancer risk and mortality. In this pilot study, we started to evaluate the effect of metformin on EMT in vivo and in vitro in endometrial cancer (EC).MethodsEndometrial cancer cell lines and freshly isolated EC tumor specimens were used to assess EMT after metformin treatment. Cell lines were subjected to wound healing and AlamarBlue assays to determine cell migration and cell proliferation; messenger RNA levels were measured by real-time reverse transcriptase (RT) quantitative polymerase chain reaction (PCR), and protein levels were measured by Western blots to detect EMT marker expression.ResultsProtein expression and messenger RNA of E-cadherin was found to be increased (P = 0.02 and 0.04, respectively) in 30 EC tumor specimens of diabetic patients treated with metformin compared with 20 EC tumor specimens of diabetic patients treated with other antidiabetic agents. In vitro, metformin reduced cell migration at 5 mM for 48 hours, as determined by the wound healing assay in EC cell lines (Ishikawa, 45% reduction; HEC50, 40% reduction), whereas more than 90% of the cells remained viable on the AlamarBlue assay. Metformin reduced EMT in the cell lines and regulated the expression of the EMT-related epithelial markers, E-cadherin and Pan-keratin; the mesenchymal markers, N-cadherin, fibronectin, and vimentin; and the EMT drivers, Twist-1, snail-1, and ZEB-1.ConclusionsTumors of patients on metformin have increased E-cadherin expression, and metformin decreases EMT in EC cell lines in vitro, suggesting clinical biological relevance of metformin in women with EC.

We have recently shown that the artemisinin derivative artemisone, which was screened against malaria in human clinical studies, is a potent inhibitor of human cytomegalovirus (HCMV). Here we evaluated the antiviral effect of artemisone when employed in 2-drug combinations with approved and experimental anti-HCMV agents. Using the Chou-Talalay method, we found that in-vitro combination of artemisone with cidofovir, brincidofovir, or with the HCMV UL97 inhibitor maribavir resulted in antiviral synergism and the combination of artemisone with ganciclovir or with the viral terminase inhibitors letermovir and BDCRB resulted in moderate synergism. Importantly, the combination of artemisone with maribavir demonstrated synergistic antiviral activity ex-vivo, in a clinically-relevant multicellular model of human placental tissues maintained in organ culture. Our findings provide the basis for the use of artemisone in synergistically acting drug combinations, to enhance viral control and reduce antiviral drug toxicities.

OBJECTIVE To describe trends and ethnic differences in incidence of gynecologic cancer in Israel. METHODS In the present retrospective epidemiologic study, age-standardized rates (ASRs) rates of gynecologic malignancies that occurred between January 1, 1993, and December 31, 2013, were extracted from the Israeli National Cancer Registry. The annual percent change (APC) was calculated separately for Jewish and Arab patients for ovarian, endometrial, and cervical cancers. RESULTS Among Jewish patients, the ASR of ovarian cancer decreased (APC -2.27%, 95% confidence interval [CI], -2.7 to -1.84; P

Pegylated liposomal doxorubicin (PLD) is used as a second-line therapy for gynecologic cancers, with a better short-term toxicity profile compared to doxorubicin or other anthracyclines. We screened 14 patients with recurrent gynecologic cancers, who underwent prolonged treatment with large cumulative doses of PLD for overt or subtle signs of cardiotoxicity (CTX) using standard and advanced echocardiography techniques [3D volumetric method for left ventricular ejection fraction (LVEF) and left ventricular/right ventricular global longitudinal strain]. Half the patients had previous echocardiographic studies available for comparison. The average PLD treatment duration was 23.6 ± 10.8 months (range 13–57), accumulating dose of 1387 ± 483 mg (range 780–2538 mg). The study group had a normal LVEF both by 2D-echo (60 ± 5%, range 50–67) and 3D echo (58 ± 5%, range 46–63). Two patients (14%) were found to have minimally reduced ejection fraction by 2D and 3D echo (50%/46% and 51%/49%, respectively) that did not meet the current definition of CTX. For the seven patients who had consecutive echocardiography studies, the average LVEF remained stable between studies (59 ± 7, 60 ± 9 and 58 ± 10.5% for the latest study, previous, p

Background Metformin has been associated with reduced cancer risk. The mechanisms underlying this cancer protective effect remain unknown. Methods "Window of opportunity" study of metformin in women with operable endometrial cancer (EC). Eleven newly diagnosed, untreated, non-diabetic patients with EC received metformin 500mg tid from diagnostic biopsy to surgery. Fasting plasma insulin, insulin-like growth factor 1 (IGF-1), insulin-like growth factor binding protein 1 (IGFBP-1) and insulin-like growth factor binding protein 7 (IGFBP-7) measurements were taken before and after metformin treatment. Ki-67, pAMPK, and pS6 immunohistochemistry staining was performed on the endometrial cancer before and after metformin treatment and was compared to a control group of 10 women with EC who did not receive metformin. Results Metformin was administered for a mean of 36.6days. None of the patients suffered side effects requiring withdrawal from the study. The study group comprised 8 patients with endometrioid EC, and 3 non-endometrioid EC, with a mean follow-up time of 57months. Mean plasma insulin ( p =0.0005), IGF-1 ( p =0.001), and IGFBP-7 ( p =0.0098) were significantly reduced after metformin treatment. A clear reduction in ki-67 and pS6 expression was observed by both conventional light microscope analysis and digital image analysis with a significant mean reduction in percentage of cells staining for ki-67 (9.7%, P =0.02) and pS6 (31%, P =0.03). In the non-treated control group expression was similar between the biopsy and the surgical specimens. Conclusions This pilot trial presents biological evidence consistent with anti-proliferative effects of metformin in women with EC in the clinical setting.

BACKGROUND: Ovarian cancer is the most lethal gynecologic cancer. High grade serous ovarian cancer (HGSC) is the most common and deadly histological subtype. The current standard treatment protocol involves primary debulking surgery followed by platinum-based combination chemotherapy. PARP inhibitors(PARPi) are the first approved personalized treatments used in BRCA1-mutated recurrent ovarian cancer patients and have shown promising clinical results. Previously published data in collaboration with Dr. Witcher's lab, we described a significant reduction in PARP1 protein levels in patients after giving standard carboplatinum-paclitaxel chemotherapy that is effecting the clinical efficacy of PARP inhibitors in clinical trials. PARP inhibitors are currently administered after standard chemotherapy, when PARP levels are the lowest which was clearly shown in the previous published paper. Applying novel strategy and following the sequence of administration, giving PARP inhibitors first followed by standard chemotherapy might improve response rates. This study aims to evaluate this strategy (in vitro) in the pre-clinical models. METHODS: BRCA1 mutated (UWB1.287, SNU-251), epigenetically silenced (OVCAR8), and wild-type BRCA1 (OVCAR3, SKOV3, A2780P & A2780R) cell lines were exposed to clinically relevant doses of PARPi, either followed by standard chemotherapy, or the inverse sequence. Therapeutic efficacy was assessed using colony formation assay. Apoptotic index was evaluated by cell cycle analysis and apoptotic assays using flow cytometry. Western Blotting was used to detect the levels of relevant apoptotic and cell cycle proteins. RESULTS: Exposure to PARPi prior to standard chemotherapy sensitized BRCA1 mutated or epigenetically silenced BRCA1 cell lines to lower doses of Cisplatin (CP) or Paclitaxel (PT). Similarly, pre-treatment with PARPi prior to chemotherapy induced apoptosis more effectively in the same cell lines. Similar results were observed in BRCA1 wild-type cell lines and cell lines in which BRCA1 functionality was restored. CONCLUSION: Pre-treatment of cell lines with PARPi followed by standard chemotherapy is more efficient (in vitro) in inhibiting growth and inducing apoptosis than the present sequence of chemotherapy followed by PARPi.

Objectives Israel is traditionally considered to have the lowest prevalence of cervical cancer compared with that in other countries of the Western world. The aim of the present study was to establish the human papillomavirus (HPV) genotypes distribution among Israeli Jewish women with premalignant and cervical cancer. Methods Fifty-two specimens with invasive cervical cancer and 50 specimens with high-grade cervical intraepithelial neoplasia (CIN2/3) were identified. Human papillomavirus genotyping in paraffin-embedded specimens was performed by deparaffinization of the tissue sections and DNA extraction, followed by HPV genotype detection using a validated polymerase chain reaction (PCR)–based HPV GenoArray test kit, to simultaneously identify 21 HPV genotypes. Results Forty-eight (48/52; 92.3%) cervical cancer samples demonstrated PCR-amplifiable DNA (non-HPV DNA). Forty (83.3%) of 48 samples were high-risk (HR) HPV positive. Six (12.5%) of 48 patients showed multiple HR HPV infections. Human papillomavirus types 16 and 18 dominated covering 28 (58.3%) and 14 (29.16%) of 48 samples. Human papillomavirus types 16 and 18 coinfected all 6 cases of multiple HR HPV infections. In CIN2/3 samples, 37 (78.7%) of 47 samples demonstrated PCR-amplifiable DNA (non-HPV DNA), and 20 (54.0%) of these 37 samples were infected by HPV. Human papillomavirus type 16 was found in 19 (95.0%) of 20 cases. Human papillomavirus type 18 was found in 3 (15.0%) of 20 cases; hence, HPV16 and HPV18 contributed to 100% of the cases. Conclusions Human papillomavirus types 16 and 18 were responsible for the vast majority of invasive cervical cancer and CIN2/3 specimens (81.2% and 100%, respectively). Therefore, it is essential to include the HPV vaccine in the vaccine schedule of the Israeli population.

Pseudomyxoma peritonei is a rare, chronic relapsing disease in which tumor cells in the abdomen produce excessive mucin with a significant mortality rate. We describe a young unmarried nulligrava who underwent fertility preservation by in vitro fertilisation and embryo cryopreservation prior to radical surgery and adjuvant chemotherapy. Pregnancy was achieved, although complicated by obstructive uropathy. She delivered a healthy infant at 32 weeks' gestation. The few descriptions of fertility and pregnancy outcome in pseudomyxoma peritonei that appear in the literature are reviewed.

Background PARP inhibitors have shown promising clinical results in cancer patients carrying BRCA1/2 mutations. Their clinical efficacy could logically be influenced by PARP1 protein levels in patient tumors. Methods We screened three cohorts of patients with ovarian cancer, totaling 313 samples, and evaluated PARP1 protein expression by immunohistochemistry with further validation by western blotting. Results We observed that up to 60 % of tumors showed little PARP1 protein expression. In serous ovarian tumors, comparing intratumoral PARP1 expression between chemo-naïve and post-chemotherapy patients revealed a decrease in intratumoral PARP1 following chemotherapy in all three cohorts (immunohistochemistry: p < 0.001, n = 239; western blot: p = 0.012, n = 74). The findings were further confirmed in a selection of matched samples from the same patients before and after chemotherapy. Conclusion Our data suggest that patients should be screened for PARP1 expression prior to therapy with PARP inhibitors. Further, the observed reduction of intratumoral PARP1 post-chemotherapy suggests that treating chemo-naïve patients with PARP inhibitors prior to the administration of chemotherapy, or concurrently, might increase the responsiveness to PARP1 inhibition. Thus, a change in the timing of PARP inhibitor administration may be warranted for future clinical trials.

To evaluate the significance of persistent lower abdominal pain in women with previous cesarean delivery.Various maternal outcomes were compared between women who underwent repeated cesareans owing to persistent lower abdominal pain (study group) and women who underwent repeated cesareans without persistent abdominal pain (control group).The incidence of uterine rupture was significantly higher in the study group than in the control group (8/81 [9.9%] vs 0/119 [0.0%]; P0.001). While all women with persistent lower abdominal pain and uterine rupture had an additional sign or symptom, only 6/73 (8.2%) women with persistent abdominal pain without uterine rupture had any additional symptoms (P0.001). There was no difference in incidence of uterine scar dehiscence between the groups. However, the hospitalization period was significantly longer in the study group (4 vs 3.7days; P0.05). Trial of labor was a contributing factor to uterine rupture.Isolated persistent lower abdominal pain in women with previous cesarean is a poor indicator of uterine rupture. However, the positive predictive value for uterine rupture is 57% when an additional sign or symptom is present. Dehiscence of the uterine scar is relatively common and it is not associated with persistent abdominal pain.

Hysterectomy is the treatment choice for patients with endometrial cancer, but progesterone may be an acceptable option for young women who wish to preserve their fertility or for women with severe co-morbidities.

Surgery remains the cornerstone in the management of patients with endometrial carcinoma. In 1988, the International Federation of Gynecology and Obstetrics (FIGO) implemented a surgical staging system for endometrial cancer that has been updated in 2009 [1]. The transition to surgical staging occurred in part because the clinically defined stage was retrospectively reassigned after examination of the surgical specimen in 25 % of the cases, and 16 % of the women with presumed stage I were found to actually have stage III or IV disease.

Objective: To investigate prematurity rate in women aged ≥45 carrying a singleton pregnancy. Other maternal and neonatal outcomes are also described. Design: Retrospective cohort study. Setting: Women delivering a singleton pregnancy at a single tertiary medical center. Population: The study included all women aged 45 years and over who delivered at 20 weeks gestation or beyond over a 9-year period from May 2000 to May 2009. Methods: Women aged 45 years and over were identified. The study group was compared to a control group of women

To investigate maternal and neonatal outcome of pregnant women infected with H1N1 influenza virus.We prospectively followed all pregnant women hospitalized with positive H1N1 influenza virus nasal polymerase chain reaction tests between September 2009 and April 2010. Maternal and neonatal complications were recorded.Twenty-four women positive for H1N1 were hospitalized. Only 2 women suffered from asthma, all others had no co-morbidities. Most women were in the third trimester (14 women, 58%). Common presenting symptoms were dyspnea (83%) and Fever (79%). Eleven women (46%) had pneumonia/Adult Respiratory Distress syndrome (ARDS) on chest X-rays. Six women were actively delivered due to maternal or fetal distress. Gestational age at delivery for these women was significantly lower (34 weeks vs. 39 weeks, p = 0.005). Of women delivered, five were admitted to intensive care units (ICU), three needed mechanical ventilation, and one tracheostomy. Patients admitted to ICU had significantly higher white blood cell (WBC) and C-reactive protein (CRP) levels (p0.01, p0.01, respectively). The main neonatal complication was prematurity where delivery was indicated.H1N1 flu pandemic has the potential of causing serious maternal morbidity during pregnancy. ARDS, elevated WBC and CRP levels correlate with more severe cases. Prematurity is associated with severity of maternal disease.
