Endometriosis is associated with increased risk of epithelial ovarian cancers (EOCs). Using data from large endometriosis and EOC genome-wide association meta-analyses, we estimate the genetic correlation and evaluate the causal relationship between genetic liability to endometriosis and EOC histotypes, and identify shared susceptibility loci. We estimate a significant genetic correlation (rg) between endometriosis and clear cell (rg = 0.71), endometrioid (rg = 0.48), and high-grade serous (rg = 0.19) ovarian cancer, associations supported by Mendelian randomization analyses. Bivariate meta-analysis identified 28 loci associated with both endometriosis and EOC, including 19 with evidence for a shared underlying association signal. Differences in the shared risk suggest different underlying pathways may contribute to the relationship between endometriosis and the different histotypes. Functional annotation using transcriptomic and epigenomic profiles of relevant tissues/cells highlights several target genes. This comprehensive analysis reveals profound genetic overlap between endometriosis and EOC histotypes with valuable genomic targets for understanding the biological mechanisms linking the diseases.

The human fallopian tube harbors the cell of origin for the majority of high-grade serous "ovarian" cancers (HGSCs), but its cellular composition, particularly the epithelial component, is poorly characterized. We perform single-cell transcriptomic profiling of around 53,000 individual cells from 12 primary fallopian specimens to map their major cell types. We identify 10 epithelial subpopulations with diverse transcriptional programs. Based on transcriptional signatures, we reconstruct a trajectory whereby secretory cells differentiate into ciliated cells via a RUNX3high intermediate. Computational deconvolution of advanced HGSCs identifies the "early secretory" population as a likely precursor state for the majority of HGSCs. Its signature comprises both epithelial and mesenchymal features and is enriched in mesenchymal-type HGSCs (p = 6.7 × 10-27), a group known to have particularly poor prognoses. This cellular and molecular compendium of the human fallopian tube in cancer-free women is expected to advance our understanding of the earliest stages of fallopian epithelial neoplasia.

PurposeInefficiencies in the clinical trial infrastructure result in protracted trial completion timelines, physician-investigator turnover, and a shrinking skilled labor force and present obstacles to research participation. Taken together, these barriers hinder scientific progress. Technological solutions to improve clinical trial efficiency have emerged, yet adoption remains slow because of concerns with cost, regulatory compliance, and implementation.MethodsA prospective pilot study that compared regulatory-compliant digital and traditional wet ink paper signatures was conducted over a 6.5-month period in a hospital-based health system. Staff time and effort, error rate, costs, and time to completion were measured. Wilcoxon rank sum tests were used to compare staff time and time to completion. A value analysis was conducted. A survey was administered to measure user satisfaction.ResultsThere where 96 participants (47 digital, 49 paper), 132 studies included (31 digital, 101 paper), and 265 documents processed (156 digital, 109 paper). A moderate reduction in staff time required to prepare documents for signature was observed (P < .0001). Error rates were reported in 5.1% of digital and 2.8% of paper documents, but this difference was not significant. Discrepancies requiring revisions included incomplete mandatory fields, inaccurate information submitted, and technical issues. A value analysis demonstrated a 19% labor savings with the use of digital signatures. Survey response rate was 57.4% (n = 27). Most participants (85.2%) preferred digital signatures. The time to complete documents was faster with digital signatures compared with paper (P = .0241).ConclusionThe use of digital signatures resulted in a decrease in document completion time and regulatory burden as represented by staff hours. Additional cost and time savings and information liquidity could be realized by integrating digital signatures and electronic document management systems.

Data from colon, breast and prostate cancers suggest that aspirin users have reduced mortality. While the direct mechanism remains uncertain, aspirin can suppress the COX-dependent and independent pathways involved in tumor progression. We hypothesized that aspirin users with clear cell ovarian cancer would have improved survival outcomes. We performed a retrospective review of patients with clear cell ovarian cancer diagnosed between 1995 and 2010, and followed outcomes through 2016. Patients underwent primary cytoreductive surgery followed by platinum-based chemotherapy. Aspirin use was defined by medication documentation in two records more than six months apart. Statistical tests included Fisher's exact, Kaplan-Meier and Cox regression analyses. Seventy-seven patients met inclusion criteria. Fifty-four patients (70%) had stage I-II disease. Thirteen patients (17%) used aspirin. Aspirin users had a statistically longer disease-free survival compared to non-users (HR 0.13, p = .018). While median disease-free survival was not reached for either group, 1 of 13 (8%) aspirin users recurred at 24 months, compared to 18 of 64 (28%) non-users. Aspirin users demonstrated longer overall survival (HR 0.13, p = .015). Median survival was not reached for aspirin users, compared to 166 months for non-users. Aspirin use retained significance (HR 0.13, p = .044) after controlling for age, stage and cytoreductive status. In this small cohort of women with clear cell ovarian cancer, aspirin use correlated with improved disease-free and overall survival, and retained independent significance as a positive prognostic factor. Further research is warranted to confirm these findings before considering aspirin as a therapeutic intervention.

Transversus abdominis plane (TAP) block is a peripheral nerve block directed at the nerves in the anterior abdominal wall. We sought to determine whether TAP block reduces post-operative narcotic use or length of stay after open gynecologic surgery. Among 98 women who underwent an open hysterectomy between July 2016 - July 2017 by a gynecologic oncologist, 73 (74.5%) received a TAP block. The majority of patients who received a TAP block had a vertical incision (86.3%) while the majority of patients who did not receive TAP block had a transverse incision (64%). More patients in the TAP block group underwent cancer debulking compared to the no TAP block group (65.7% versus 8%). The two groups did not differ in post-operative pain scores on day 1, 2, or 3, cumulative narcotic use by post-operative day 3, length of stay, or ileus. We found TAP block after vertical skin incision results in comparable pain scores, narcotic use, and length of stay compared to patients undergoing transverse incisions without TAP block.

BACKGROUND: Observational studies suggest greater height is associated with increased ovarian cancer risk, but cannot exclude bias and/or confounding as explanations for this. Mendelian randomisation (MR) can provide evidence which may be less prone to bias. METHODS: We pooled data from 39 Ovarian Cancer Association Consortium studies (16,395 cases; 23,003 controls). We applied two-stage predictor-substitution MR, using a weighted genetic risk score combining 609 single-nucleotide polymorphisms. Study-specific odds ratios (OR) and 95% confidence intervals (CI) for the association between genetically predicted height and risk were pooled using random-effects meta-analysis. RESULTS: Greater genetically predicted height was associated with increased ovarian cancer risk overall (pooled-OR (pOR) = 1.06; 95% CI: 1.01-1.11 per 5 cm increase in height), and separately for invasive (pOR = 1.06; 95% CI: 1.01-1.11) and borderline (pOR = 1.15; 95% CI: 1.02-1.29) tumours. CONCLUSIONS: Women with a genetic propensity to being taller have increased risk of ovarian cancer. This suggests genes influencing height are involved in pathways promoting ovarian carcinogenesis.

An objective evaluation of patient performance status (PS) is difficult because patients spend the majority of their time outside of the clinic, self-report to providers, and undergo dynamic changes throughout their treatment experience. Real-time, objective activity data may allow for a more accurate assessment of PS and physical function, while reducing the subjectivity and bias associated with current assessments. Consenting patients with advanced cancer wore a wearble activity monitor for three consecutive visits in a prospective, single-cohort clinical trial. Provider-assessed PS (ECOG/Karnofsky) and NIH PROMIS® patient-reported outcomes (PROs) were assessed at each visit. Associations between wearable activity monitor metrics (steps, distance, stairs) and PS, clinical outcomes (adverse events, hospitalizations, survival), and PROs were assessed using correlation statistics and in multivariable logistic regression models. Thirty-seven patients were evaluated (54% male, median 62 years). Patients averaged 3700 steps, 1.7 miles, and 3 flights of stairs per day. Highest correlations were observed between average daily steps and ECOG-PS and KPS (r = 0.63 and r = 0.69, respectively p < 0.01). Each 1000 steps/day increase was associated with reduced odds for adverse events (OR: 0.34, 95% CI 0.13, 0.94), hospitalizations (OR: 0.21 95% CI 0.56, 0.79), and hazard for death (HR: 0.48 95% CI 0.28-0.83). Significant correlations were also observed between activity metrics and PROs. Our trial demonstrates the feasibility of using wearable activity monitors to assess PS in advanced cancer patients and suggests their potential use to predict clinical and patient-reported outcomes. These findings should be validated in larger, randomized trials.

Objective To address a deficiency in clinical trial and research enrollment in gynecologic cancer studies, we launched a paper based patient research registry. To improve registry enrollment, we transitioned to an online registry and trial matching mechanism to aid women in accessing open studies. Methods Utilizing a validated verification platform, we designed a web-based registry and trial matching mechanism for women over age 18. Participants completed a questionnaire to provide information for trial matching. A focus group of registry participants was held 9 months after the start of the study to evaluate barriers to participation. Results A total of 322 women were enrolled in the online registry over a 14 month period which was a 4.3 fold increase over the paper-based registry (p < 0.0001). Two hundred and sixty three (82%) women were matched to at least one study. Fifteen percent (39/263) of those eligible for studies went on to enroll. The online enrollment rate to studies was not different from that observed in the paper-based registry (26/172, p = 0.934), however, the web-based registry linked participants to subsequent studies 27% more rapidly (68 (+/- 98) days vs. 93 (+/- 81) days for the paper-based registry, p = 0.017). Focus group participants identified areas for improvement. Conclusion Web-based patient driven registry provides dramatic improvement in the number of participants enrolled and the time to trial linkage compared to a paper based registry at a single institution. Further studies of barriers to research participation are necessary to improve on this model.

ObjectiveHigh-grade vaginal intraepithelial neoplasia (VAIN) II-III has a variable clinical course. Due to the rarity of VAIN, existing data on the efficacy of treatment, risk of recurrence and progression to carcinoma is limited. Our objective was to evaluate predictors of recurrent disease and describe the risk of progression to carcinoma.MethodsUnder an IRB-approved protocol 42 patients with biopsy-proven VAIN II-III from 1995 to 2015 were retrospectively identified. Demographics, treatment, and clinical course were abstracted from medical records. Patients were followed with semi-annual colposcopy and biopsies at physician discretion. Standard statistical analyses were applied.ResultsMedian patient age was 58years old (range 20-81). Median follow-up time was 45months (range 9-195). Management included excision (31%), laser ablation (33%), topical agents (19%), and observation (10%), with the following rates of recurrence: 38%, 43%, 75%, and 50% (p=0.26). 20 patients (48%) had recurrent or persistent disease during treatment follow-up. No specific primary treatment was significantly more effective in preventing recurrence. Recurrence of VAIN II-III occurred at a median of 17.4months (7-78months) from time of initial diagnosis. Five (12%) patients developed invasive cancer of the lower genital tract. Median time to cancer diagnosis was 64months (30 to 101months).ConclusionsPatients with VAIN II-III are at high risk of recurrence and progression, suggesting the need for ongoing evaluation with cytology and comprehensive colposcopy by a skilled specialist. There were no clear risk factors or histopathologic criteria which predicted recurrence or progression to cancer.

ObjectiveTo report the frequency and features of occult carcinomas and the incidence of subsequent cancers following risk-reducing salpingo-oophorectomy (RRSO) in BRCA mutation carriers.Methods257 consecutive women with germline BRCA mutations who underwent RRSO between January 1, 2000 and December 31, 2014 were identified in an Institutional Review Board approved study. All patients were asymptomatic with normal physical exams, CA 125 values, and imaging studies preoperatively, and had at least 12months of follow-up post-RRSO. All patients had comprehensive adnexal sectioning performed. Patient demographics and clinico-pathologic characteristics were extracted from medical and pathology records.ResultsThe cohort included 148 BRCA1, 98 BRCA2, 6 BRCA not otherwise specified (NOS), and 5 BRCA1 and 2 mutation carriers. Occult carcinoma was seen in 14/257 (5.4%) of patients: 9 serous tubal intraepithelial carcinomas (STIC), 3 tubal cancers, 1 ovarian cancer, and 1 endometrial cancer. Three patients (1.2%) with negative pathology at RRSO subsequently developed primary peritoneal serous carcinoma (PPSC), and 2 of 9 patients (22%) with STIC subsequently developed pelvic serous carcinoma. 110 women (43%) were diagnosed with breast cancer prior to RRSO, and 14 of the remaining 147 (9.5%) developed breast cancer following RRSO. Median follow-up of the cohort was 63months.ConclusionIn this cohort, 5.4% of asymptomatic BRCA mutation carriers had occult carcinomas at RRSO, 86% of which were tubal in origin. The risk of subsequent PPSC for women with benign adnexa at RRSO is low; however, the risk of pelvic serous carcinoma among women with STIC is significantly higher.

Objective This study describes the patterns of end of life (EOL) discussions and their impact on the use of aggressive measures in women with terminal gynecologic malignancies at a single institution. Methods An IRB-approved retrospective chart review identified 136 patients who died of gynecologic cancer between 2010 and 2012 with at least one interaction with their oncologists in the last 6 months of life. Aggressive measures were defined as chemotherapy within the last 14 days of life, emergency department (ED) visits, hospital and intensive care unit (ICU) admissions within the last 30 days of life, and inpatient deaths. The frequency and timing of EOL conversations were recorded. Utilization of hospice care was also described. Results In the last 30 days of life, 54 (40%) patients were evaluated in the ED, 67 (49%) were admitted into hospital, and 16 (12%) were admitted to the ICU. Thirteen patients (10%) had chemotherapy in the last 14 days of life. Ninety-seven (71%) patients had a documented EOL conversation, eighteen (19%) as outpatients, and 79 (81%) as inpatients. Thirty (22%) patients died in the hospital. At the time of death, 55 (40%) patients were enrolled in outpatient hospice care. The mean amount of time in hospice was 28 days. Conclusions End of life care discussions rarely occurred in the outpatient setting or > 30 days before death. Inpatient encounters led to discussions about hospice and code status. Evaluation in the ED frequently resulted in escalation of care. Earlier EOL care discussions resulted in less aggressive measures.

ObjectivesA growing body of evidence supports a role for thrombocytosis in the promotion of epithelial ovarian cancer biology. However, studies have only linked preoperative platelet count at time of initial cytoreductive surgery to clinical outcome. Here, we sought to determine the impact of elevated platelet count at time of secondary cytoreductive surgery (SCS) for recurrent disease.MethodsUnder an IRB-approved protocol, we identified 107 women with invasive epithelial ovarian cancer who underwent SCS between January 1997 and June 2012. We reviewed clinical, laboratory, and pathologic records from this retrospective cohort. The data was analyzed using the chi-squared, Fisher's exact, Cox proportional hazards, and Kaplan-Meier tests. We defined thrombocytosis as a platelet count ≥ 350 × 10(9)/L and optimal resection at SCS as microscopic residual disease.ResultsThirteen of 107 women (12%) with recurrent ovarian cancer had thrombocytosis prior to SCS. Preoperative thrombocytosis at SCS was associated with failure to undergo optimal resection (p=0.0001). Women with preoperative thrombocytosis at time of SCS demonstrated shorter overall survival (33 months) compared to those with normal platelet counts (46 months, p=0.004). On multivariate analysis, only preoperative platelet count retained significance as an independent prognostic factor (p=0.025) after controlling for age at SCS (p=0.90), disease free interval from primary treatment (0.06), and initial stage of disease (0.66).ConclusionsElevated platelet count at time of SCS is associated with suboptimal resection and shortened overall survival. These data provide further evidence supporting a plausible role for thrombocytosis in aggressive ovarian tumor biology.

ObjectiveThere are few studies analyzing surveillance for Type II endometrial cancer recurrence. Our objective was to determine the types of post treatment surveillance tests performed in our institution and the efficacy of these tests in detecting recurrence in type II endometrial cancer patients.MethodsOne hundred and thirty six cases of type II endometrial cancers at Cedars-Sinai Medical Center from January of 2000 to August of 2011 were identified and 106 patients met inclusion criteria. Medical charts were reviewed for surveillance methods and number of follow up visits. For patients who underwent a recurrence of disease, the surveillance method utilized for detection was documented.ResultsForty-seven of the 106 (44%) patients developed recurrence with a mean progression free interval of 11 months. All patients had a history and physical at each surveillance visit, 78% had Pap testing, 57% had CA-125 levels drawn, 59% had CT (computed tomography) scans done, 6% had PET (positron emission tomography) scans done for surveillance. In our cohort, recurrence was detected by symptoms in 16, by CA-125 in 11, by physical exam in 7, by CT scan in 12, and by PET scan in one patient. No patients had recurrence detected by vaginal cytology.ConclusionsAlthough performed in the majority of patients, Pap testing did not detect any recurrences within this cohort. History and physical exam detected the most recurrences. These findings suggest that educating patients about relevant symptoms and performing thorough follow-up exams may be the most important aspects of detecting type II endometrial cancer recurrence.
