The association of maintenance hormone therapy with overall survival in advanced-stage low-grade serous ovarian carcinoma: A risk-set matched retrospective study.

OBJECTIVE: We conducted a multi-institutional observational study to investigate whether maintenance hormone therapy following primary treatment of low-grade advanced-stage ovarian cancer (LGSOC) is associated with an overall survival advantage. METHODS: We included patients with histologically confirmed stage III or IV LGSOC diagnosed between Jan 1, 2004, and Dec 31, 2019, treated in Commission on Cancer-accredited cancer programs in the US. Patients who received hormone therapy within six months of diagnosis were matched to controls who did not initiate hormone therapy during this timeframe by risk-set propensity score matching. The primary outcome was the risk of death from any cause within five years of initiation of HT or observation. RESULTS: There were 296 patients who initiated maintenance hormone therapy within six months of diagnosis and 2805 potential controls. Patients who received hormone therapy were more often treated in academic medical centers (55% vs. 44%), diagnosed later in the study period (62% vs. 23% diagnosed in 2018-2019), and frequently received no chemotherapy during initial treatment (45% vs. 17%). After risk set propensity score matching, we identified 225 patients treated with HT and 225 untreated controls who were otherwise similar with respect to measured covariates. In the matched cohort, hormone therapy was associated with a reduction in the risk of death (hazard ratio 0.60; 95% CI 0.38-0.94), corresponding to a 60-month survival of 75% compared with 65%. CONCLUSIONS: Following primary management of LGSOC, maintenance hormone therapy was associated with improved overall survival compared with observation.

Supporting Our Physician Parents (SOPPort): A pilot program for parental wellness at the Massachusetts General Hospital.

Physician parents encounter unique challenges in balancing new parenthood with work responsibilities, especially upon their return from parental leave. We designed a pilot program that incorporated 1:1 parental coaching to expectant and new physician parents and provided stipends for lactation support and help at home. Additional initiatives included launching a virtual new parent group during the COVID-19 pandemic and starting an emergency backup pump supplies program. There was positive feedback for our Parental Wellness Program (PWP), which was used to secure expanded funding. Pilot results showed that our program had a meaningful impact on parental wellness, morale, productivity, and lactation efforts.

Patterns of spread and genetic alterations of primary endometrioid carcinomas of the ovary.

OBJECTIVE: The primary objective was to characterize the rate of lymph node involvement in a cohort of patients with primary ovarian endometrioid adenocarcinoma. Additionally, we sought to quantify the recurrence rate, genetic alterations, and impact of lymphadenectomy on survival in this group of patients. METHODS: Patients diagnosed with primary endometrioid adenocarcinoma of the ovary without synchronous carcinomas of the female genital tract between 2012 and 2021 were identified. Demographic and disease-related data were collected from pathology reports and clinical records. Kaplan-Meier survival analysis using log rank test and Cox regression was performed. RESULTS: Sixty-three patients met inclusion criteria. Median age was 60 (range 22-90) years. Histologic grade was 1 in 20 (32%), 2 in 27 (43%), and 3 in 16 (25%) tumors. International Federation of Gynecology and Obstetrics (FIGO) stage after surgery included IA/B (n=20, 32%), IC (n=23, 37%), II (n=16, 25%), and III (n=4, 6%). Forty-one (65%) patients had pelvic and 33 (52%) had both pelvic and para-aortic lymphadenectomy. All assessed lymph nodes were negative for metastatic carcinoma. No patients with clinically pelvis-confined disease had tumors upstaged by either lymphadenectomy or omentectomy. Twenty-eight patients (44%) had germline mutational status documented; two had a germline BRCA mutation, confirmed to be pathogenic by molecular studies. Complete staging did not significantly impact progression free or overall survival, after adjusting for age and histologic grade in a Cox proportional hazards model. The recurrence rate was 15% for patients with grade 1 endometrioid carcinoma, 7% for grade 2, and 31% for grade 3, respectively. CONCLUSION: There were no lymph node metastases in patients with comprehensively staged primary endometrioid ovarian carcinoma. Staging did not impact survival and may be omitted, regardless of grade. Germline BRCA mutations are rare in ovarian endometrioid carcinoma compared with reported rates in high-grade serous carcinomas.

Trends in the use of neoadjuvant chemotherapy for low-grade serous ovarian cancer in the United States.

OBJECTIVE: To describe trends in neoadjuvant chemotherapy (NACT) use for low-grade serous ovarian carcinoma (LGSOC) and to quantify associations between NACT and extent of cytoreductive surgery. METHODS: We identified women treated for stage III or IV serous ovarian cancer in a Commission on Cancer accredited program between January 2004-December 2020. Regression models were developed to evaluate trends in NACT use for LGSOC, to identify factors associated with receipt of NACT, and to quantify associations between NACT and bowel or urinary resection at the time of surgery. Demographic and clinical factors were used for confounder control. RESULTS: We observed 3350 patients who received treatment for LGSOC during the study period. The proportion of patients who received NACT increased from 9.5% in 2004 to 25.9% in 2020, corresponding to an annual percent change of 7.2% (95% CI 5.6-8.9). Increasing age (rate ratio (RR) 1.15; 95% CI 1.07-1.24), and stage IV disease (RR 2.66; 95% CI 2.31-3.07) were associated with a higher likelihood of receiving NACT. For patients with high-grade disease, NACT was associated with a decrease in likelihood of bowel or urinary surgery (35.3% versus 23.9%; RR 0.68, 95% CI 0.65-0.71). For LGSOC, NACT was associated with a higher likelihood of these procedures (26.6% versus 32.2%; RR 1.24, 95% CI 1.08-1.42). CONCLUSION: NACT use among patients with LGSOC has increased from 2004 to 2020. While NACT was associated with a lower rate of gastrointestinal and urinary surgery among patients with high-grade disease, patients with LGSOC receiving NACT were more likely to undergo these procedures.

Black and hispanic women have less support during cancer evaluation and treatment: results from a prospective patient reported outcomes program in gynecologic malignancy.

OBJECTIVE: Race remains a significant predictor of poor outcomes in women with gynecologic cancer and minority patients consistently report worse quality of life during cancer treatment. Disparities between patients in strength of social and emotional supports may contribute to these outcomes. This study's objective was to describe the racial differences in patient reported outcomes of women being evaluated or treated for a gynecologic malignancy at a large tertiary cancer hospital. METHODS: In this prospective cohort study, all patients presenting for care at a tertiary care gynecologic oncology clinic between January 2018 and September 2019 were evaluated for inclusion. All patients were administered validated patient reported outcome measure questionnaires at serial visits. Demographic data was gathered including self-reported race. Patients were characterized as White, Black, Asian, Hispanic/Latino, or Other. Patient reported outcomes were compared between respondents of different races using linear and logistic regression. RESULTS: Between January 2018 to September 2019, 2022 patients with a known race completed questionnaires. Of these patients, 86.7% were White, 4.3% Black, and 4.9% Hispanic/Latino and 58.7% had a known cancer diagnosis. Non-White patients were significantly less likely to complete questionnaires (p<0.001). Non-White patients reported significantly lower levels of emotional support on all questions (Patient-Reported Outcomes Measurement Information System (PROMIS) emotional support: Q1 p<0.001, Q2 p<0.001, Q3 p=0.013, Q4 p=0.002), and lower overall emotional (p=0.005) and instrumental (p=0.005) support scores when compared with White patients. Hispanic/Latino patients reported the lowest levels of emotional and instrumental support and more cognitive (p=0.043) and financial (p=0.040) difficulties associated with treatment. Black women reported having less support with chores while sick (p=0.014) and being less likely to have someone to talk to (p=0.013). CONCLUSIONS: Significant differences exist in patient reported outcomes between women of different racial backgrounds. Hispanic/Latino and Black women have less support during gynecologic cancer evaluation and treatment as compared with White women.

Association of hospital-level factors with utilization of sentinel lymph node biopsy in patients with early-stage vulvar cancer.

OBJECTIVE: To evaluate utilization of sentinel lymph node biopsy (SLNB) for early-stage vulvar cancer at minority-serving hospitals and low-volume facilities. METHODS: Between 2012-2018, individuals with T1b vulvar squamous cell carcinoma were identified using the National Cancer Database. Patient, facility, and disease characteristics were compared between patients undergoing SLNB or inguinofemoral lymph node dissection (IFLD). Multivariable logistic regression, adjusted for patient, facility, and disease characteristics, was used to evaluate factors associated with SLNB. Kaplan-Meier survival analysis using log rank test and Cox regression was performed. RESULTS: Of the 3,532 patients, 2,406 (68.1%) underwent lymph node evaluation, with 1,704 (48.2%) undergoing IFLD and 702 (19.8%) SLNB. In a multivariable analysis, treatment at minority-serving hospitals (OR 0.39, 95% CI 0.19-0.78) and low-volume hospitals (OR 0.44, 95% CI 0.28-0.70) were associated with significantly lower odds of undergoing SLNB compared to receiving care at non-minority-serving and high-volume hospitals, respectively. While SLNB utilization increased over time for the entire cohort and stratified subgroups, use of the procedure did not increase at minority-serving hospitals. After controlling for patient and tumor characteristics, SLNB was not associated with worse OS compared to IFLD in patients with positive (HR 1.02, 95% CI 0.63-1.66) or negative (HR 0.92, 95% CI 0.70-1.21) nodal pathology. CONCLUSIONS: For patients with early-stage vulvar cancer, treatment at minority-serving or low-volume hospitals was associated with significantly decreased odds of undergoing SLNB. Future efforts should be concentrated toward ensuring that all patients have access to advanced surgical techniques regardless of where they receive their care.

Guideline-Discordant Care in Early-Stage Vulvar Cancer.

OBJECTIVE: To describe the use of National Comprehensive Cancer Network guideline-concordant inguinofemoral lymph node (LN) evaluation in individuals with early-stage vulvar cancer. METHODS: This retrospective cohort study identified patients with T1b and T2 vulvar squamous cell carcinoma diagnosed between 2012 and 2018 using the National Cancer Database. Factors associated with LN evaluation were examined using logistic regression analyses, adjusting for patient, disease, and facility-level characteristics. Kaplan-Meier survival analysis using log rank test and Cox regression was performed for the entire cohort and a subgroup of older patients , defined as individuals aged 80 years or older. RESULTS: Of the 5,685 patients with vulvar cancer, 3,756 (66.1%) underwent guideline-concordant LN evaluation. In our adjusted model, age 80 years or older (odds ratio [OR], 0.30; 95% CI 0.22-0.42) and Black race (OR 0.72; 95% CI 0.54-0.95) were associated with lower odds of LN evaluation. High-volume hospitals were associated with increased odds of LN evaluation compared with low-volume hospitals (OR 1.62; 95% CI 1.28-2.05). Older individuals who did not undergo LN evaluation had significantly worse overall survival than those with pathologically negative LNs (hazard ratio [HR] 0.45; 95% CI 0.37-0.55) and similar overall survival as those with pathologically positive LNs (HR 1.05; 95% CI 0.77-1.43). CONCLUSION: Guideline-concordant LN evaluation for early-stage vulvar squamous cell carcinoma is low. Lower utilization is associated with older age, Black race, and care at a low-volume hospital.

Patient-reported outcomes and chemotherapy-related cognitive impairment in gynecologic malignancy.

OBJECTIVE: Chemotherapy has multiple adverse effects, including chemotherapy-related cognitive impairment, the phenomenon colloquially referred to as 'chemobrain'. The objective of this study was to understand patient-reported experiences of this phenomenon in relation to chemotherapy administration among gynecologic oncology patients. METHODS: A prospective patient-reported outcomes program was implemented in the Gynecologic Oncology clinic of a tertiary academic institution in January 2018. Patients with endometrial or ovarian cancer who received chemotherapy were included through September 2019 in this cohort study. Patients completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire. Serial responses were compared before, during, and after chemotherapy using a mixed effects linear regression with random effects for repeated measures within patients and a fixed effect for endometrial versus ovarian cancer. RESULTS: Fifty patients were included who completed a total of 152 patient-reported outcome measures. Thirty-five questionnaires were administered before chemotherapy, 59 during treatment, and 58 at a median of 161 days after the final cycle of chemotherapy. Seventy-one percent of patients reported no difficulties with concentration before chemotherapy, which remained stable after chemotherapy (72%). Sixty-six percent reported no difficulty with memory before chemotherapy versus 52% after chemotherapy. There were significant differences in feeling tension (p<0.001), worry (p<0.001), and depression (p=0.02) before and after chemotherapy on mixed effects linear regression, with higher levels of adverse emotional symptoms before chemotherapy administration compared with after. Women reported more interference with their social lives during chemotherapy (mean 1.08) compared with before (mean 0.85) and after chemotherapy (0.75, p=0.04). CONCLUSIONS: While no overt memory issues were discovered with serial administration of patient-reported outcome measures, rates of adverse emotional symptoms such as depression, tension, and worry diminished after chemotherapy administration. Further study is needed about the phenomenon of chemotherapy-related cognitive impairment using a larger cohort.

Initial findings from a prospective, large scale patient reported outcomes program in patients with gynecologic malignancy.

INTRODUCTION: Patient reported outcome measures (PROMs) are associated with improved overall survival in patients with metastatic malignancy; however, routine collection of PROMs is nascent. Little is known about PROs in women with gynecologic malignancy outside of a trial setting, limiting our understanding of how routine populations experience treatment, disease and morbidity. The goal of this study was to prospectively collect and describe disease-specific PROs in a non-trial population of women with gynecologic malignancy. METHODS: PROMs were assigned electronically to all patients presenting for care in our gynecologic oncology clinic. Patients received a general oncology questionnaire (EORTC QLQ C30) a disease specific questionnaire (FACT V, EORTC EN24, EORTC OV28, EORTC Cx 24), and questionnaires assessing support at home. Responses were mapped to relevant clinical variables. Descriptive statistics were performed, and comparisons made with parametric and nonparametric analyses. The association between support at home and perioperative complications was assessed via logistic regression. RESULTS: In the study period, 3239 unique patients were evaluated at new patient visits, post-operative visits, chemotherapy visits and surveillance visits with a PROMs completion rate of 78.1% (n = 2530 women with 4402 completions). There was no difference in completion rates based on age or self-identified race. The EORTC QLQ C-30 questionnaire was able to adequately discern differences between disease sites. Overall, scores were lower than those obtained in trial populations. PROMs responses were not associated with perioperative complications. CONCLUSION: Systematic collection of PROMs is feasible and tech-enabled workflows result in high collection rates. Quality of life scores in our clinic population were lower than published data, indicating caution should be used when extrapolating quality of life data from clinical trials to counseling and decision making around routine patient populations.

Lymph node assessment at the time of hysterectomy has limited clinical utility for patients with pre-cancerous endometrial lesions.

OBJECTIVE: The objective of this study was to determine the proportion of patients with a pre-invasive endometrial lesion who meet Mayo criteria for lymph node dissection on final pathology to determine if the use of sentinel lymph node biopsy in patients with pre-invasive lesions would be warranted. METHODS: All women who underwent hysterectomy for a pre-invasive endometrial lesion (atypical hyperplasia or endometrial intra-epithelial neoplasia) between 2009 and 2019 were included for analysis. Relevant statistical tests were utilized to test the associations between patient, operative, and pathologic characteristics. RESULTS: 141 patients met inclusion criteria. 51 patients (36%) had a final diagnosis of cancer, the majority (96%) of which were Stage IA grade 1 endometrioid carcinomas. Seven patients (5%) met Mayo criteria on final pathology (one grade 3, seven size >2 cm, one >50% myoinvasive). Three of these seven patients had lymph nodes assessed of which 0% had metastases. Six of these patients had frozen section performed, and 2 met (33%) Mayo criteria intraoperatively. Of the seven patients in the overall cohort that had lymph node sampling, six had a final diagnosis of cancer and none had positive lymph nodes. Of the 51 patients with cancer, only 10 had cancer diagnosed using frozen section, and only two met intra-operative Mayo criteria. Age > 55 was predictive of meeting Mayo criteria on final pathology (p = 0.007). No patients experienced a cancer recurrence across a median follow up of 24.3 months. CONCLUSIONS: Atypical hyperplasia and endometrial intra-epithelial neoplasia portend low risk disease and universal nodal assessment is of limited value.

Patient reported outcome measures among patients with vulvar cancer at various stages of treatment, recurrence, and survivorship.

OBJECTIVE: Our goal was to pragmatically describe patient reported outcomes (PROs) in a typical clinic population of vulvar cancer patients, as prior studies of vulvar cancer PROs have examined clinical trial participants. METHODS: A prospective PRO program was implemented in the Gynecologic Oncology clinic of a tertiary academic institution in January 2018. Vulvar cancer patients through September 2019 were administered the European Organization for the Research and Treatment of Cancer Quality of life Questionnaire, the Patient Reported Outcome Measurement Information System Instrumental and Emotional Support Scales, and the Functional Assessment of Cancer Therapy-Vulvar questionnaire. Binary logistic regressions were performed to determine adjusted odds ratios for adverse responses to individual questions by insurance, stage, age, time since diagnosis, recurrence, radiation, and surgical radicality. RESULTS: Seventy vulvar cancer patients responded to PROs (85.4% response rate). Seventy-one percent were > 1 year since diagnosis, 61.4% had stage I disease, and 28.6% recurred. Publicly insured women had less support and worse quality of life (QOL, aOR 4.15, 95% CI 1.00-17.32, p = 0.05). Women who recurred noted more interference with social activities (aOR 4.45, 95% CI 1.28-15.41, p = 0.019) and poorer QOL (aOR 5.22 95% CI 1.51-18.10, p = 0.009). There were no major differences by surgical radicality. Those >1 year since diagnosis experienced less worry (aOR 0.17, 95% CI 0.04-0.63, p = 0.008). CONCLUSIONS: Surgical radicality does not affect symptoms or QOL in vulvar cancer patients, whereas insurance, recurrence, and time since diagnosis do. This data can improve counseling and awareness of patient characteristics that would benefit from social services referral.

Ready for the robot? A cross-sectional survey of OB/GYN fellowship directors' experience and expectations of their incoming fellow's robotic surgical skills.

To describe OB/GYN fellowship directors' (FDs) observations, expectations, and preferences of incoming fellow's robotic surgery preparedness. Cross-sectional study. OB/GYN FDs in gynecologic oncology, minimally invasive gynecologic surgery, female pelvic medicine and reconstructive surgery, and reproductive endocrinology and infertility in the United States. 60 FDs answered the questionnaire. Participants completed an online questionnaire about their preferences and expectations of robotic surgery experience for incoming fellows. FDs observed that many incoming first-year fellows had a baseline understanding of robotic technology (60%) and robotic bedside assist experience (53%). However, few could perform more advanced robotic tasks; with FDs indicating fellows could infrequently robotically suture (18%), or perform the entire hysterectomy (15%). FDs reported higher composite observation than expectation scores (34.3 versus 22.2, p < 0.0001), and higher preference than expectation scores (34.0 versus 22.2, p < 0.0001). The composite expectation score of high-volume divisions was greater than of low-volume divisions (23.7 versus 14.0, p = 0.04). Among the domains identified, FDs most strongly preferred their fellows be able to bedside assist, have a basic understanding of robotic technology, and have basic robotic operative skills. While incoming fellows have more robotic skill than their FDs expect, few are deemed competent to independently operate the robot. Higher volume robotic surgery divisions have higher expectations of the robotic skills of their incoming fellows compared to low-volume divisions; however, FDs neither expected nor preferred their incoming fellows to be fully competent in all aspects of robotic surgery.

CT prediction of surgical outcome in patients with advanced epithelial ovarian carcinoma undergoing neoadjuvant chemotherapy.

OBJECTIVE: A scoring system has been proposed to predict gross residual disease at primary debulking surgery (PDS) for advanced epithelial ovarian cancer. This scoring system has not been assessed in patients undergoing neoadjuvant chemotherapy (NACT). The aim of this study is to assess the reproducibility and prognostic significance of the scoring system when applied to women undergoing NACT followed by interval debulking surgery (IDS). METHODS: A retrospective cohort study was conducted of patients with advanced ovarian cancer who underwent NACT and IDS between 2005 and 2014. Change in tumor burden using computed tomography (CT) at diagnosis (T0) and after initiation of NACT but before IDS (T1) was independently assessed by two radiologists blinded to outcomes using two read criteria: a scoring system utilizing clinical and radiologic criteria and RECIST 1.1. Relationship between CT assessments to surgical outcome, progression free survival (PFS) and overall survival (OS) were evaluated. Reader agreement was measured using Fleiss's kappa (ĸ). RESULTS: 76 patients were analyzed. Optimal surgical outcome was achieved in 69 (91%) of patients. Median progression free survival was 13.2 months and overall survival was 32.6 months, respectively. Predictive score change from T0 to T1 of >1 (denoting an improvement in disease burden) was associated with optimal cytoreduction (p = 0.02 and 0.01 for readers 1 and 2, respectively). Neither predictive score nor RECIST 1.1 assessment was predictive of OS or PFS. Reader agreement was substantial for predictive score (κ = 0.77) and moderate for RECIST (κ = 0.51) assessments. CONCLUSIONS: A change in score before and after neoadjuvant chemotherapy minimizes reader variability and predicts surgical outcome.

Racial and ethnic disparities over time in the treatment and mortality of women with gynecological malignancies.

OBJECTIVE: To examine temporal trends in treatment and survival among black, Asian, Hispanic, and white women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. METHODS: Using the National Cancer Database (2004-2014), we identified women diagnosed with endometrial, ovarian, cervical, and vulvar cancer. For each disease site, we analyzed race/ethnicity-specific trends in receipt of evidence-based practices. Professional societies' recommendations were used to define these practices. Using data from the Surveillance, Epidemiology, and End Results Program (2000-2009) we analyzed trends in 5-year survival. RESULTS: Throughout the study period black (64.8%) and Hispanic (68.3%) women were less likely to undergo lymphadenectomy for stage I ovarian cancer compared to Asian (79.5%) and white patients (74.6%). Black women were the least likely group to undergo lymphadenectomy in all periods. Among patients with stage II-IV ovarian cancer, 76.6% of white and Asian women received both surgery and chemotherapy, compared to 70.8% of black and 73.9% Hispanic women. Hispanic women with deeply invasive or high-grade stage I endometrial cancer underwent lymphadenectomy less frequently (74.5%) than all other groups (80.7%). Black women were less likely to have chemo-radiotherapy for stage IIB-IVA cervical cancer (75.6% versus 80.4% of all others). Black women were also less likely to have a surgical lymph node evaluation for vulvar cancer (58.8% versus 63.5% of all others). Among women diagnosed with ovarian, endometrial, and cervical cancer, black women had lower five-year survival than other groups. CONCLUSION: Significant racial disparities persist in the delivery of evidence-based care. Black women with ovarian, endometrial, and cervical cancer continue to experience higher cancer-specific mortality than other groups.

Meigs to modern times: The evolution of debulking surgery in advanced ovarian cancer.

Joe V. Meigs was a visionary clinician and an early adopter of radical techniques in the surgical treatment of ovarian cancer. His 1934 textbook "Tumors of the Female Pelvic Organs", consolidated his approach to this "hopeless" disease, with pearls on diagnosis, outcomes, and even speculations about the benefits of minimally invasive surgery. Decades before adjuvant chemotherapy would prove of value, and in an era when sophisticated statistics were unheard of, he nonetheless tried to eke out what benefits he could using the methods available in his time. We transition his original findings and observations through the advent of platinum-based chemotherapy, retrospective cohort studies supporting the benefits of primary debulking, and finally the long-awaited randomized controlled trial. We aim to provide historical context for the underpinnings of how cytoreductive surgery has evolved into its current role in the treatment of advanced ovarian cancer.

Complete Remission Following Pembrolizumab in a Woman with Mismatch Repair-Deficient Endometrial Cancer and a Germline BRCA1 Mutation.

Endometrial cancer is the most common gynecologic malignancy in the U.S. and, although the majority of cases present at an early stage and can be treated with curative intent, those who present with advanced disease, or develop metastatic or recurrent disease, have a poorer prognosis. A subset of endometrial cancers exhibit mismatch repair (MMR) deficiency. It is now recognized that MMR-deficient cancers are particularly susceptible to programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors, and in a landmark judgement in 2017, the U.S. Food and Drug Administration granted accelerated approval to pembrolizumab for these tumors, the first tumor-agnostic approval of a drug. However, less is known about the sensitivity to PD-1 blockade among patients with known mutations in double-strand break DNA repair pathways involving homologous recombination, such as those in BRCA1 or BRCA2. Here we report a case of a patient with an aggressive somatic MMR-deficient endometrial cancer and a germline BRCA1 who experienced a rapid complete remission to pembrolizumab. KEY POINTS: Endometrial cancers, and in particular endometrioid carcinomas, should undergo immunohistochemical testing for mismatch repair proteins.Uterine cancers with documented mismatch repair deficiency are candidates for treatment with programmed cell death protein 1 inhibition.Genomic testing of recurrent, advanced, or metastatic tumors may be useful to determine whether patients are candidates for precision therapies.

Anal and Cervical High-Risk Human Papillomavirus Genotyping in Women With and Without Genital Neoplasia.

OBJECTIVE: The aim of the study was to compare the prevalence, genotypes, and rates of concomitant anal and cervical high-risk human papillomavirus (HR-HPV) in women with and without a history of HPV-related genital neoplasia. MATERIALS AND METHODS: This was a prospective cohort study conducted from December 2012 to February 2014. Women with a history of neoplasia were considered the high-risk group. Women without a history of neoplasia were considered the low-risk group. Cervical and anal cytology and HPV genotyping were performed. All women with abnormal anal cytology were referred for anoscopy. RESULTS: One hundred eighty-four women met inclusion criteria. High-risk HPV was detected in the anal canal of 17.4% of the high-risk group and 1.5% of the low-risk group (p = .003). High-risk HPV was detected in the cervix of 30.5% of the high-risk group and 7.6% of the low-risk group (p < .001). Concomitant anal and cervical high-risk HPV was detected in 4.4% of the high-risk group and was not detected in the low-risk group (p = .2). Among women with anal intraepithelial neoplasia 2 or greater (n = 5), 60% had HR-HPV detected in the anal canal while none had HR-HPV detected in the cervix. CONCLUSIONS: Women with a history of genital neoplasia are more likely to be positive for anal and cervical HR-HPV compared with women without a history of genital neoplasia. Although there was no significant difference in rates of concomitant HR-HPV between low- and high-risk groups, HR-HPV can be found concomitantly in the anus and the cervix and may be associated with anal intraepithelial neoplasia or carcinoma.

Factors associated with delivery of neoadjuvant chemotherapy in women with advanced stage ovarian cancer.

PURPOSE: To identify clinical and non-clinical factors associated with utilization of primary cytoreductive surgery (PCS) or neoadjuvant chemotherapy (NACT) in women with advanced stage epithelial ovarian cancer (EOC). METHODS: Using the National Cancer Database, we identified women with stage IIIC and IV EOC diagnosed from 2012 to 2014. The primary outcome was receipt of NACT, defined in the primary analysis as utilization of chemotherapy as the first cancer-directed therapy, irrespective of whether interval surgery was performed. Univariable and multivariable associations between clinical and non-clinical factors and receipt of NACT were investigated using mixed-effect logistic regression models. A secondary analysis excluded women who received primary chemotherapy but did not receive interval cytoreductive surgery. RESULTS: Among 17,302 eligible women, 10,948 (63.3%) underwent PCS and 6354 (36.7%) received NACT. Older age, stage IV disease, high-grade, and serous histology were associated with receipt of NACT in univariate (p<0.001) and multivariable analyses (p<0.001). Analysis of non-clinical factors revealed that residency in the Northeast region and receipt of treatment closer to home were associated with NACT in univariate (p<0.05) but not multivariable analysis (p>0.05). In multivariable analysis, African-American race/ethnicity (p=0.04), low-income level (p=0.02), treatment in high-volume centers (p<0.01), and insurance by Medicare or other government insurance (p<0.001) were associated with receipt of NACT. When women who received no surgery were excluded, all factors that were independent predictors of NACT in the main analysis remained significant, except for race/ethnicity. CONCLUSIONS: Non-clinical factors were associated with the use of NACT at a magnitude similar to that of clinically relevant factors.
