RESUMO
BACKGROUND: Enhanced recovery after surgery (ERAS) pathways utilize multimodal analgesia. In pathways already utilizing incisional injection of liposomal bupivacaine (ILB), we assessed the benefit of adding intrathecal opioid analgesia (ITA). METHODS: In this randomized controlled non-inferiority trial in patients undergoing laparotomy for gynecologic malignancy, we allocated patients 1:1 to ILB alone versus ITA + ILB with 150 µg intrathecal hydromorphone. The primary endpoint was the Overall Benefit of Analgesia Score (OBAS) at 24 h following surgery. Secondary endpoints included pain scores, intravenous opioid use, and cost of care. RESULTS: Demographic and surgical factors were balanced for 105 patients. For the primary endpoint, ILB alone was non-inferior to ITA + ILB (median OBAS at 24 h of 4 vs 4; p = 0.70). We observed a significant reduction in the need for intravenous opioids (26% vs 71%; p < 0.001) and total opioid requirements (median 7.5 vs 39.3 mg morphine equivalents, p < 0.001) in the first 24 h. Clinically relevant improvements in pain scores were identified in the first 16 h after surgery favoring ITA + ILB. Total cost of the index episode, pharmacy costs, and costs at 30 days were not statistically different. CONCLUSIONS: Using OBAS as the primary endpoint, ILB alone was non-inferior to ITA + ILB. However, important cost-neutral benefits for ITA + ILB in the first 24 h post-operatively included lower pain scores and reduced need for intravenous opioids. These early, incremental benefits of adding ITA to ERAS bundles already utilizing ILB should be considered to optimize immediate post-operative pain.
RESUMO
OBJECTIVES: Our objectives were to determine the incidence, timing, and risk factors for venous thromboembolisms (VTEs) in patients with advanced stage epithelial ovarian cancer (EOC) who received neoadjuvant chemotherapy (NACT). We explored the utilization of direct-acting oral anticoagulants (DOACs) for VTE treatment. METHODS: This retrospective cohort study included patients with advanced stage EOC receiving NACT followed by interval cytoreductive surgery (ICS) at a single institution. Risk factors were compared between patients with versus without VTE between EOC diagnosis and 180 days after ICS. Bleeding complications were compared between patient who received a DOAC versus non-DOAC. RESULTS: VTE cases occurred amongst 33 of the 154 (21.4%) patients with 4 (2.6%) concurrent with EOC diagnosis, 9 (5.8%) between EOC diagnosis and NACT start, 13 (8.4%) between NACT start and ICS, and 7 (4.5%) within 180 days after ICS. There were no statistically significant differences in risk factors assessed (age, body mass index, functional status, histology, Khorana score, and smoking history) between patients with versus without VTE. Eleven patients (33.3%) received a DOAC for VTE treatment. There were no significant differences in number of intraoperative blood transfusions (p = 0.38), blood loss (p = 0.95), or bleeding complications (p = 0.53) between patients treated with a DOAC versus a non-DOAC. CONCLUSION: There is a high incidence of VTE events (21.4%) in patients with advanced stage EOC undergoing NACT. Two-thirds of the VTEs may have been prevented with thromboprophylaxis as they occurred between EOC diagnosis and ICS. These data support consideration of thromboprophylaxis in all patients with advanced stage EOC undergoing NACT.

OBJECTIVE: Alterations in DNA methylation are early events in endometrial cancer (EC) development and may have utility in EC detection via tampon-collected vaginal fluid. METHODS: For discovery, DNA from frozen EC, benign endometrium (BE), and benign cervicovaginal (BCV) tissues underwent reduced representation bisulfite sequencing (RRBS) to identify differentially methylated regions (DMRs). Candidate DMRs were selected based on receiver operating characteristic (ROC) discrimination, methylation level fold-change between cancers and controls, and absence of background CpG methylation. Methylated DNA marker (MDM) validation was performed using qMSP on DNA from independent EC and BE FFPE tissue sets. Women ≥45 years of age with abnormal uterine bleeding (AUB) or postmenopausal bleeding (PMB) or any age with biopsy-proven EC self-collected vaginal fluid using a tampon prior to clinically indicated endometrial sampling or hysterectomy. Vaginal fluid DNA was assayed by qMSP for EC-associated MDMs. Random forest modeling analysis was performed to generate predictive probability of underlying disease; results were 500-fold in-silico cross-validated. RESULTS: Thirty-three candidate MDMs met performance criteria in tissue. For the tampon pilot, 100 EC cases were frequency matched by menopausal status and tampon collection date to 92 BE controls. A 28-MDM panel highly discriminated between EC and BE (96% (95%CI 89-99%) specificity; 76% (66-84%) sensitivity (AUC 0.88). In PBS/EDTA tampon buffer, the panel yielded 96% (95% CI 87-99%) specificity and 82% (70-91%) sensitivity (AUC 0.91). CONCLUSION: Next generation methylome sequencing, stringent filtering criteria, and independent validation yielded excellent candidate MDMs for EC. EC-associated MDMs performed with promisingly high sensitivity and specificity in tampon-collected vaginal fluid; PBS-based tampon buffer with added EDTA improved sensitivity. Larger tampon-based EC MDM testing studies are warranted.

BACKGROUND: Extramammary Paget's disease recurs often after traditional surgical excision. Margin-controlled surgery improves the recurrence rate for male genital disease but is less studied for female anatomy. OBJECTIVE: This study aimed to compare surgical and oncologic outcomes of margin-controlled surgery vs traditional surgical excision for female genital Paget's disease. STUDY DESIGN: We conducted a prospective observational trial of patients with vulvar or perianal Paget's disease treated with surgical excision guided by Mohs micrographic surgery between 2018 and 2022. The multidisciplinary protocol consisted of office-based scouting biopsies and modified Mohs surgery followed by surgical excision with wound closure under general anesthesia. Modified Mohs surgery cleared peripheral disease margins using a moat technique with cytokeratin 7 staining. Medial disease margins (the clitoris, urethra, vagina, and anus) were assessed using a hybrid of Mohs surgery and intraoperative frozen sections. Surgical and oncologic outcomes were compared with the outcomes of a retrospective cohort of patients who underwent traditional surgical excision. The primary outcome was 3-year recurrence-free survival. RESULTS: Three-year recurrence-free survival was 93.3% for Mohs-guided excision (n=24; 95% confidence interval, 81.5%-100.0%) compared to 65.9% for traditional excision (n=63; 95% confidence interval, 54.2%-80.0%) (P=.04). The maximum diameter of the excisional specimen was similar between groups (median, 11.3 vs 9.5 cm; P=.17), but complex reconstructive procedures were more common with the Mohs-guided approach (66.7% vs 30.2%; P<.01). Peripheral margin clearance was universally achieved with modified Mohs surgery, but positive medial margins were noted in 9 patients. Reasons included intentional organ sparing and poor performance of intraoperative hematoxylin and eosin frozen sections without cytokeratin 7. Grade 3 or higher postoperative complications were rare (0.0% for Mohs-guided excision vs 2.4% for traditional excision; P=.99). CONCLUSION: Margin control with modified Mohs surgery significantly improved short-term recurrence-free survival after surgical excision for female genital Paget's disease. Use on medial anatomic structures (the clitoris, urethra, vagina, and anus) is challenging, and further optimization is needed for margin control in these areas. Mohs-guided surgical excision requires specialized, collaborative care and may be best accomplished at designated referral centers.

PURPOSE: Postoperative venous thromboembolism (VTE) can potentially be associated with significant morbidity, mortality, and healthcare costs. The aim of this study was to determine the utilization of Caprini guideline indicated VTE in elective gynecologic surgery patients and its impact on postoperative VTE and bleeding complications. METHODS: This was a retrospective cohort study of elective gynecologic surgical procedures performed between January 1, 2016, and May 31, 2021. Two study cohorts were generated: (1) those who received and (2) those who did not receive VTE prophylaxis based on Caprini score risk stratification. Outcome measures were then compared between the study cohorts and included the development of a VTE up to 90-days postoperatively. Secondary outcome measures included postoperative bleeding events. RESULTS: A total of 5471 patients met inclusion criteria and the incidence of VTE up to 90 days postoperatively was 1.04%. Overall, 29.6% of gynecologic surgery patients received Caprini score-based guideline VTE prophylaxis. 39.2% of patients that met high-risk VTE criteria (Caprini > 5) received appropriate Caprini score-based prophylaxis. In multivariate regression analysis, the American Society of Anesthesiologists (ASA) score (OR 2.37, CI 1.27-4.45, p < 0.0001) and Caprini score (OR 1.13, CI 1.03-1.24, p = 0.008) predicted postoperatively VTE occurrence. Increasing Charlson comorbidity score (OR 1.39, CI 1.31-1.47, P < 0.001) ASA score (OR 1.36, CI 1.19-1.55, P < 0.001) and Caprini score (OR 1.10, CI 1.08-1.13, P < 0.001) were associated with increased odds of receiving appropriate inpatient VTE prophylaxis. CONCLUSION: While the overall incidence of VTE was low in this cohort, enhanced adherence to risk-based practice guidelines may provide more patient benefit than harm to postoperative gynecologic patients.

OBJECTIVE: The evaluation of women with perimenopausal abnormal uterine bleeding (AUB) and postmenopausal bleeding (PMB) to detect endometrial cancer (EC) and its precursors is not standardized and can vary widely. Consequently, costs associated with the workup and management undoubtedly vary. This study aimed to quantify costs of AUB/PMB evaluation to understand the healthcare burden associated with securing a pathologic diagnosis. METHODS: Women ≥45 years of age presenting to a single institution gynecology clinic with AUB/PMB for diagnostic workup were prospectively enrolled February 2013-October 2017 for a lower genital tract biospecimen research study. Clinical workup of AUB/PMB was determined by individual provider discretion. Costs of care were collected from administrative billing systems from enrollment to 90 days post enrollment. Costs were standardized and inflation-adjusted to 2017 US Dollars (USD). RESULTS: In total, there were 1017 women enrolled with 5.6% diagnosed with atypical hyperplasia or endometrial cancer (EC). Within the full cohort, 90-day median cost for AUB/PMB workup and management was $2279 (IQR $512-4828). Among patients with a diagnostic biopsy, median 90-day costs ranged from $2203 (IQR $499-3604) for benign or disordered proliferative endometrium (DPE) diagnosis to $21,039 (IQR $19,084-24,536) for a diagnosis of EC. CONCLUSIONS: The costs for diagnostic evaluation of perimenopausal AUB and PMB vary greatly according to ultimate tissue-based diagnosis. Even reassuring benign findings that do not require further intervention-the most common in this study's cohort-yield substantial costs. The development of sensitive, specific, and more cost-effective diagnostic strategies is warranted.

OBJECTIVE: Aberrant DNA methylation is an early event in carcinogenesis which could be leveraged to detect ovarian cancer (OC) in plasma. METHODS: DNA from frozen OC tissues, benign fallopian tube epithelium (FTE), and buffy coats from cancer-free women underwent reduced representation bisulfite sequencing (RRBS) to identify OC MDMs. Candidate MDM selection was based on receiver operating characteristic (ROC) discrimination, methylation fold change, and low background methylation among controls. Blinded biological validation was performed using methylated specific PCR on DNA extracted from independent OC and FTE FFPE tissues. MDMs were tested using Target Enrichment Long-probe Quantitative Amplified Signal (TELQAS) assays in pre-treatment plasma from women newly diagnosed with OC and population-sampled healthy women. A random forest modeling analysis was performed to generate predictive probability of disease; results were 500-fold in silico cross-validated. RESULTS: Thirty-three MDMs showed marked methylation fold changes (10 to >1000) across all OC subtypes vs FTE. Eleven MDMs (GPRIN1, CDO1, SRC, SIM2, AGRN, FAIM2, CELF2, RIPPLY3, GYPC, CAPN2, BCAT1) were tested on plasma from 91 women with OC (73 (80%) high-grade serous (HGS)) and 91 without OC; the cross-validated 11-MDM panel highly discriminated OC from controls (96% (95% CI, 89-99%) specificity; 79% (69-87%) sensitivity, and AUC 0.91 (0.86-0.96)). Among the 5 stage I/II HGS OCs included, all were correctly identified. CONCLUSIONS: Whole methylome sequencing, stringent filtering criteria, and biological validation yielded candidate MDMs for OC that performed with high sensitivity and specificity in plasma. Larger plasma-based OC MDM studies, including testing of pre-diagnostic specimens, are warranted.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years following diagnosis. The NCCN Guidelines for Ovarian Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up for patients with ovarian, fallopian tube, and primary peritoneal cancers. These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines, including revised guidance on alternative chemotherapy regimens for patients with advanced age and/or comorbidities, a new algorithm for recurrent low-grade serous carcinoma based on developing research and novel therapeutic agents, and updated language regarding tumor molecular analysis applications in ovarian cancer.

OBJECTIVE: PI3K-AKT pathway mutations initiate a kinase cascade that characterizes endometrial cancer (EC). As kinases seldom cause oncogenic transformation without dysregulation of antagonistic phosphatases, pivotal interactions governing this pathway were explored and correlated with clinical outcomes. METHODS: After exclusion of patients with POLE mutations from The Cancer Genome Atlas EC cohort with endometrioid or serous EC, the study population was 209 patients with DNA sequencing, quantitative gene-specific RNA expression, copy number variation (CNV), and surveillance data available. Extracted data were annotated and integrated. RESULTS: A PIK3CA, PTEN, or PIK3R1 mutant (-mu) was present in 83% of patients; 57% harbored more than 1 mutation without adversely impacting progression-free survival (PFS) (P = .10). PIK3CA CNV of at least 1.1 (CNV high [-H]) was detected in 26% and linked to TP53-mu and CIP2A expression (P < .001) but was not associated with PFS (P = .24). PIK3CA expression was significantly different between those with CIP2A-H and CIP2A low (-L) expression (the endogenous inhibitor of protein phosphatase 2A [PP2A]), when stratified by PIK3CA mutational status or by PIK3CA CNV-H and CNV-L (all P < .01). CIP2A-H or PPP2R1A-mu mitigates PP2A kinase dephosphorylation, and FBXW7-mu nullifies E3 ubiquitin ligase (E3UL) oncoprotein degradation. CIP2A-H and PPP2R1A-mu (PP2A impairment) and FBXW7-mu (E3UL impairment) were associated with compromised PFS (P < .001) and were prognostically discriminatory for PIK3CA-mu and PIK3CA CNV-H tumors (P < .001). Among documented recurrences, 84% were associated with impaired PP2A (75%) and/or E3UL (20%). CONCLUSION: PP2A and E3UL deficiencies are seminal biological drivers in EC independent of PIK3CA-mu, PTEN-mu, and PIK3R1-mu and PIK3CA CNV.

OBJECTIVE: Emerging technologies may enable detection of endometrial cancer with methods that are less invasive than standard biopsy methods. This study compares patient pain scores among 3 office gynecologic tract sampling methods and explores their potential determinants. METHODS: A prospective study including 3 sampling methods (tampon, Tao brush (TB), endometrial biopsy (EB)) was conducted between December 2015 and August 2017 and included women ≥45 years of age presenting with abnormal uterine bleeding, postmenopausal bleeding, or thickened endometrial stripe. Patients rated pain after each sampling procedure using a 100-point visual analog scale (VAS). RESULTS: Of 428 enrolled, 190 (44.39%) patients underwent all 3 sampling methods and reported a VAS score for each. Nearly half were postmenopausal (n = 93, 48.9%); the majority were parous (172, 90.5%) of which 87.8% had at least one vaginal delivery. Among the 190 patients, the median (IQR) pain score was significantly lower for sampling via tampon (0 [0,2]) compared to TB (28 [12, 52]) or EB (32 [15, 60]) (both p < 0.001, Wilcoxon signed rank test). Among women who underwent tampon sampling, age and pain scores showed a weak positive correlation (Spearman rank correlation, r = 0.14; p = 0.006); EB sampling was associated with a weak inverse correlation between parity and pain scores (r = -0.14; p = 0.016). CONCLUSION: Gynecologic tract sampling using a tampon had significantly lower pain than both EB and TB. Pain with tampon sampling was positively correlated with age and pain with EB sampling was inversely correlated with parity. Pain scores for TB and EB were not significantly related to age, menopausal status, or BMI.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and is the country's fifth most common cause of cancer mortality in women. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. These NCCN Guidelines discuss cancers originating in the ovary, fallopian tube, or peritoneum, as these are all managed in a similar manner. Most of the recommendations are based on data from patients with the most common subtypesâhigh-grade serous and grade 2/3 endometrioid. The NCCN Guidelines also include recommendations specifically for patients with less common ovarian cancers, which in the guidelines include the following: carcinosarcoma, clear cell carcinoma, mucinous carcinoma, low-grade serous, grade 1 endometrioid, borderline epithelial, malignant sex cord-stromal, and malignant germ cell tumors. This manuscript focuses on certain aspects of primary treatment, including primary surgery, adjuvant therapy, and maintenance therapy options (including PARP inhibitors) after completion of first-line chemotherapy.

OBJECTIVE: To assess the performance of endometrial thickness (ET) cut-offs for detecting endometrial cancer (EC) in women with postmenopausal bleeding (PMB) and evaluate the clinical utility of additional ultrasound measures such as endometrial volume (EV), vascular flow index (VFI), vascularization index (VI), and uterine artery flow index (FI). METHODS: Clinicaltrials.gov and MEDLINE database via PubMed were queried for studies published between 1/1990 and 3/2016 using specific MeSH terms. Original, peer-reviewed cohort studies reporting EC outcomes and specific ultrasound findings by PMB status were included. RESULTS: Study design, country, clinical setting inclusion/exclusion criteria, aggregate study-level demographic and clinical data were extracted from 44 studies including 17,339 women with PMB and 1341 cases of EC (7.7%). In women with PMB and EC (n = 417), pooled mean ET was 16.4 mm (95% CI, 14.8-18.1 mm). In women with PMB without EC, pooled mean ET was 4.1 mm. 31 studies reported outcomes using different ET cut-off values ranging from 3 to 20 mm. Compared to ≥3 or 4 mm, a cutoff of ≥5 mm had similar sensitivity (96.2, 95%CI 92.3, 98.1) with improved specificity for EC (51.5, 95%CI 42.3-60.7), allowing to reduce the rate of invasive workup for PMB by 17%. EV, VI, VFI, and FI were significantly correlated with EC, but performance of specific cut-offs was not analyzed due to limited data. CONCLUSION: Among women with PMB mean ET is substantially higher in women with EC compared to those without EC. An ET cutoff of ≥5 mm shows an acceptable tradeoff between sensitivity and specificity for diagnosis of EC.

OBJECTIVE: To assess the incidence, treatment, and outcomes in patients with invasive vulvar extramammary Paget's disease (EMPD) in a national cohort of patients. METHODS: Patients from the Surveillance, Epidemiology and End Results (SEER) database with diagnoses of vulvar EMPD from 1992 to 2016 were included. Demographic, treatment, and outcome data were analyzed. RESULTS: A total of 1268 cases of invasive EMPD were identified. Of those, 69.6% had localized disease, 12.0% regional disease, 1.3% distant disease, and 17.1% were unstaged. The annual incidence of invasive vulvar EMPD was 0.36 per 100,000 person years: rates have increased >2-fold since 1992 (1992: 0.19 per 100,000 person years to 0.50 per 100,000 person years in 2016). Most patients underwent primary surgery (n = 1034; 81.5%). Five-year cancer specific survival (CSS) was 95.5% and was associated with stage. Compared to patients with localized disease, patients with distant metastases had dramatically worse CSS (HR: 85.8 (31.8-248) p < 0.0001). Synchronous cancers (diagnosed within one calendar year of EMPD diagnosis year) were observed in 35 cases (2.8%), and 195 patients (15.4%) developed a secondary malignancy (diagnosed >one year from year of EMPD diagnosis year). The most common synchronous breast, gastrointestinal tract, melanoma and the most common secondary cancers were breast, gastrointestinal tract and genitourinary tract. CONCLUSIONS: The incidence of invasive vulvar EMPD has increased over time. CSS is excellent for localized disease, but those with metastatic disease are in need of novel therapies. Approximately 15% will develop a secondary malignancy, indicating that patients with invasive vulvar EMPD should undergo site specific preventative health screens during recurrence surveillance.

OBJECTIVE: To determine whether analysis of methylated DNA in benign endometrial biopsy (EB) specimens is associated with risk of endometrial cancer (EC). METHODS: We identified 23 women with EBs performed at Mayo Clinic diagnosed as normal (n = 14) or hyperplasia (n = 9) and who later developed endometrial cancer after a median interval of 1 year. Cases were matched 1:1 with patients with benign EBs who did not develop EC (controls) by histology of benign EB (normal endometrium vs. endometrial hyperplasia without atypia), date of EB, age at EB, and length of post-biopsy follow-up. DNA extracted from formalin-fixed paraffin-embedded tissues underwent pyrosequencing to determine percent methylation of promoter region CpGs at 26 loci in 4 genes (ADCYAP1, HAND2, MME, RASSF1A) previously reported as methylated in EC. RESULTS: After pathologic review, 23 matched pairs of cases and controls were identified (14 normal, 9 hyperplasia without atypia per group). Among cases, median time from benign EB to EC was 1 year (range 2 days - 9.2 years). We evaluated 26 CpG sites within 4 genes and found a consistent trend of increasing percentage of methylation from control to case to EC for all CpGs. At the gene-level, mean methylation events of ADCYAP1 and HAND2 in cases were significantly higher than control (p = 0.015 and p = 0.021, respectively). Though the other genes did not reach statistical significance, we observed an increased methylation trend among all genes. Area-under-curve (AUC) calculations (predicting future development of EC in the setting of benign EB) for ADCYAP1 and HAND2 were 0.71 (95% CI 0.55-0.88) and 0.83 (95% CI 0.64-1, respectively). CONCLUSIONS: This proof-of-principle study provides evidence that specific methylation patterns in benign EB correlate with future development of EC.

OBJECTIVE: To evaluate endometrial cancer (EC) risk assessment and early detection strategies in high-risk populations, we designed a large, prospective cohort study of women undergoing endometrial evaluation to assess risk factors and collect novel biospecimens for future testing of emerging EC biomarkers. Here we report on the baseline findings of this study. METHODS: Women aged ≥45 years were enrolled at the Mayo Clinic from February 2013-June 2018. Risk factors included age, body mass index (BMI), smoking, oral contraceptive and hormone therapy use, and parity. We collected vaginal tampons, endometrial biopsies, and Tao brush samples. We estimated mutually-adjusted odds ratios (OR) and 95% confidence intervals (CI) using multinomial logistic regression; outcomes included EC, atypical hyperplasia, hyperplasia without atypia, disordered proliferative endometrium, and polyps, versus normal endometrium. RESULTS: Subjects included 1205 women with a mean age of 55 years; 55% were postmenopausal, and 90% had abnormal uterine bleeding. The prevalence of EC was 4.1% (n = 49), predominantly diagnosed in postmenopausal women (85.7%). Tampons and Tao brushings were obtained from 99% and 68% of women, respectively. Age (OR 1.14, 95% CI 1.1-1.2) and BMI (OR 1.39, 95% CI 1.1-1.7) were positively associated with EC; atypical hyperplasia (OR 1.07, 95% CI 1.0-1.1; OR 2.00, 95% CI 1.5-2.6, respectively), and polyps (OR 1.06, 95% CI 1.0-1.1; OR 1.17, 95% CI 1.0-1.3, respectively); hormone therapy use and smoking were inversely associated with EC (OR 0.42, 95%, 0.2-0.9; OR 0.43, 95% CI, 0.2-0.9, respectively). Parity and past oral contraception use were not associated with EC. CONCLUSIONS: Well-established EC risk factors may have less discriminatory accuracy in high-risk populations. Future analyses will integrate risk factor assessment with biomarker testing for EC detection.

OBJECTIVE: We aimed to assess whether endometrial cancer (EC) can be detected in shed DNA collected with vaginal tampon by analyzing copy number, methylation markers, and mutations. METHODS: Tampons were collected prior to hysterectomy from 38 EC patients and 28 women with benign indications. Extracted tampon DNA underwent the following: 1) low-coverage whole genome sequencing (LC-WGS) to assess copy number, 2) pyrosequencing to measure percent promotor methylation of HOXA9, RASSF1, and CDH13 and 3) next generation sequencing (NGS) to identify mutations in 19 genes associated with EC identified through The Cancer Genome Atlas. Sensitivity and specificity for each test and test combinations were calculated. RESULTS: Methylation analysis yielded the highest specificities but lowest sensitivities (37-40% sensitivity; 100% specificity for HOXA9, RASSF1 and HTR1B) while mutation analysis had improved sensitivity (50% sensitivity; 83% specificity). Only one "false positive" result for copy number variants was identified among women with benign surgical indications, which was based on detection of copy number changes, and associated with a leiomyosarcoma that was only recognized at hysterectomy. Considering any of the 3 biomarker classes as a positive, resulted in a sensitivity of 92% and specificity of 86%. Mutation analysis did not add sensitivity to the combination of analysis of copy number and methylation. CONCLUSIONS: This study demonstrates a proof-of-principle for non-invasive yet precise detection of endometrial cancer. We propose that with improved biomarker testing, it may be possible to develop a clinically useful test for detecting EC.

OBJECTIVES: This study aimed to assess the association between hormone replacement therapy and the incidence of subsequent malignancies in patients who underwent risk-reducing salpingo-oophorectomy and had mutations predisposing them to Müllerian cancers. METHODS: This Institutional Review Board-approved retrospective study was performed at five academic institutions. Women were included if they were age 18-51 years, had one or more confirmed germline highly penetrant pathogenic variants, and underwent risk-reducing salpingo-oophorectomy. Patients with a prior malignancy were excluded. Clinicodemographic data were collected by chart review. Patients with no documented contact for one year prior to study termination were called to confirm duration of hormone use and occurrence of secondary outcomes. Hormone replacement therapy included any combination of estrogen or progesterone. RESULTS: Data were analyzed for 159 women, of which 82 received hormone replacement therapy and 77 did not. In both groups an average of 6 years since risk reduction had passed. The patients treated with hormone replacement therapy did not have a higher risk of subsequent malignancy than those not treated with hormone replacement therapy (6 out of 82 vs. 7 out of 77, P = .68). Patients who received hormone replacement therapy were younger than those who did not receive hormone replacement therapy (39.0 vs. 43.9 years, P < .01) and were more likely to have undergone other risk reductive procedures including mastectomy and/or hysterectomy, though this difference was not statistically significant (69.5% vs. 55.8%, P = .07). CONCLUSIONS: In this multi-institution retrospective study of data from patients with high-risk variant carriers who underwent risk-reducing salpingo-oophorectomy, there was no statistically significant difference in the incidence of malignancy between women who did and did not receive hormone replacement therapy.

The COVID-19 pandemic has challenged our ability to provide timely surgical care for our patients. In response, the U.S. Surgeon General, the American College of Srugeons, and other surgical professional societies recommended postponing elective surgical procedures and proceeding cautiously with cancer procedures that may require significant hospital resources and expose vulnerable patients to the virus. These challenges have particularly distressing for women with a gynecologic cancer diagnosis and their providers. Currently, circumstances vary greatly by region and by hospital, depending on COVID-19 prevalence, case mix, hospital type, and available resources. Therefore, COVID-19-related modifications to surgical practice guidelines must be individualized. Special consideration is necessary to evaluate the appropriateness of procedural interventions, recognizing the significant resources and personnel they require. Additionally, the pandemic may occur in waves, with patient demand for surgery ebbing and flowing accordingly. Hospitals, cancer centers and providers must prepare themselves to meet this demand. The purpose of this white paper is to highlight all phases of gynecologic cancer surgical care during the COVID-19 pandemic and to illustrate when it is best to operate, to hestitate, and reintegrate surgery. Triage and prioritization of surgical cases, preoperative COVID-19 testing, peri-operative safety principles, and preparations for the post-COVID-19 peak and surgical reintegration are reviewed.

BACKGROUND: Most endometrial cancer cases are preceded by abnormal uterine bleeding, offering a potential opportunity for early detection and cure of endometrial cancer. Although clinical guidelines exist for diagnostic workup of abnormal uterine bleeding, consensus is lacking regarding optimal management for women with abnormal bleeding to diagnose endometrial cancer. OBJECTIVE: We report the baseline data from a prospective clinical cohort study of women referred for endometrial evaluation at the Mayo Clinic, designed to evaluate risk stratification in women at increased risk for endometrial cancer. Here, we introduce a risk-based approach to evaluate diagnostic tests and clinical management algorithms in a population of women with abnormal bleeding undergoing endometrial evaluation at the Mayo Clinic. STUDY DESIGN: A total of 1163 women aged ≥45 years were enrolled from February 2013 to May 2019. We evaluated baseline absolute risks and 95% confidence intervals of endometrial cancer and endometrial intraepithelial neoplasia according to clinical algorithms for diagnostic workup of women with postmenopausal bleeding (assessment of initial vs recurrent bleeding episode and endometrial thickness measured through transvaginal ultrasound). We also evaluated risks among women with postmenopausal bleeding according to baseline age (<60 vs 60+ years) as an alternative example. For this approach, biopsy would be conducted for all women aged 60+ years and those aged <60 years with an endometrial thickness of >4 mm. We assessed the clinical efficiency of each strategy by estimating the percentage of women who would be referred for endometrial biopsy, the percentage of cases detected and missed, and the ratio of biopsies per case detected. RESULTS: Among the 593 women with postmenopausal bleeding, 18 (3.0%) had endometrial intraepithelial neoplasia, and 47 (7.9%) had endometrial cancer, and among the 570 premenopausal women with abnormal bleeding, 8 (1.4%) had endometrial intraepithelial neoplasia, and 7 (1.2%) had endometrial cancer. Maximum risk was noted in women aged 60+ years (17.7%; 13.0%-22.3%), followed by those with recurrent bleeding (14.7%; 11.0%-18.3%). Among women with an initial bleeding episode for whom transvaginal ultrasound was recommended, endometrial thickness did not provide meaningful risk stratification: risks of endometrial cancer and endometrial intraepithelial neoplasia were nearly identical in women with an endometrial thickness of >4 mm (5.8%; 1.3%-10.3%) and ≤4 mm (3.6%; 0.9%-8.6%). In contrast, among those aged <60 years with an endometrial thickness of >4 mm, the risk of endometrial cancer and endometrial intraepithelial neoplasia was 8.4% (4.3%-12.5%), and in those with an endometrial thickness of ≤4 mm, the risk was 0% (0.0%-3.0%; P=.01). The most efficient strategy was to perform biopsy in all women aged 60+ years and among those aged <60 years with an endometrial thickness of >4 mm, with the lowest percentage referred to biopsy while still detecting all cases. CONCLUSION: Existing clinical recommendations for endometrial cancer detection in women with abnormal bleeding are not consistent with the underlying risk. Endometrial cancer risk factors such as age can provide important risk stratification compared with the assessment of recurrent bleeding. Future research will include a formal assessment of clinical and epidemiologic risk prediction models in our study population as well as validation of our findings in other populations.

Eleven genes have been identified that increase the lifetime risk of developing ovarian cancer. The cumulative cancer risk of ovarian cancer varies with the mutation type and age. Ovarian cancer risk management options include surgical risk reduction with salpingo-oophorectomy and a newer step-wise approach with interval salpingectomy and delayed oophorectomy. Women should be counseled on the pros and cons of hysterectomy in the setting of reducing the risk of other cancers; eliminating the risk of endometrial cancer in Lynch Syndrome, potential risk of serous/serous-like endometrial cancer in BRCA1 carriers, and elimination of progestogen therapy that may increase breast cancer risk.
