RESUMEN
BACKGROUND: Neutralizing monoclonal antibodies (nmAbs) failed to show clear benefit for hospitalized patients with coronavirus disease 2019 (COVID-19). Dynamics of virologic and immunologic biomarkers remain poorly understood. METHODS: Participants enrolled in the Therapeutics for Inpatients with COVID-19 trials were randomized to nmAb versus placebo. Longitudinal differences between treatment and placebo groups in levels of plasma nucleocapsid antigen (N-Ag), anti-nucleocapsid antibody, C-reactive protein, interleukin-6, and D-dimer at enrollment, day 1, 3, and 5 were estimated using linear mixed models. A 7-point pulmonary ordinal scale assessed at day 5 was compared using proportional odds models. RESULTS: Analysis included 2149 participants enrolled between August 2020 and September 2021. Treatment resulted in 20% lower levels of plasma N-Ag compared with placebo (95% confidence interval, 12%-27%; P < .001), and a steeper rate of decline through the first 5 days (P < .001). The treatment difference did not vary between subgroups, and no difference was observed in trajectories of other biomarkers or the day 5 pulmonary ordinal scale. CONCLUSIONS: Our study suggests that nmAb has an antiviral effect assessed by plasma N-Ag among hospitalized patients with COVID-19, with no blunting of the endogenous anti-nucleocapsid antibody response. No effect on systemic inflammation or day 5 clinical status was observed. CLINICAL TRIALS REGISTRATION: NCT04501978.

BACKGROUND: Severe coronavirus disease 2019 (Covid-19) is associated with dysregulated inflammation. The effects of combination treatment with baricitinib, a Janus kinase inhibitor, plus remdesivir are not known. METHODS: We conducted a double-blind, randomized, placebo-controlled trial evaluating baricitinib plus remdesivir in hospitalized adults with Covid-19. All the patients received remdesivir (≤10 days) and either baricitinib (≤14 days) or placebo (control). The primary outcome was the time to recovery. The key secondary outcome was clinical status at day 15. RESULTS: A total of 1033 patients underwent randomization (with 515 assigned to combination treatment and 518 to control). Patients receiving baricitinib had a median time to recovery of 7 days (95% confidence interval [CI], 6 to 8), as compared with 8 days (95% CI, 7 to 9) with control (rate ratio for recovery, 1.16; 95% CI, 1.01 to 1.32; P = 0.03), and a 30% higher odds of improvement in clinical status at day 15 (odds ratio, 1.3; 95% CI, 1.0 to 1.6). Patients receiving high-flow oxygen or noninvasive ventilation at enrollment had a time to recovery of 10 days with combination treatment and 18 days with control (rate ratio for recovery, 1.51; 95% CI, 1.10 to 2.08). The 28-day mortality was 5.1% in the combination group and 7.8% in the control group (hazard ratio for death, 0.65; 95% CI, 0.39 to 1.09). Serious adverse events were less frequent in the combination group than in the control group (16.0% vs. 21.0%; difference, -5.0 percentage points; 95% CI, -9.8 to -0.3; P = 0.03), as were new infections (5.9% vs. 11.2%; difference, -5.3 percentage points; 95% CI, -8.7 to -1.9; P = 0.003). CONCLUSIONS: Baricitinib plus remdesivir was superior to remdesivir alone in reducing recovery time and accelerating improvement in clinical status among patients with Covid-19, notably among those receiving high-flow oxygen or noninvasive ventilation. The combination was associated with fewer serious adverse events. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT04401579.).

Microglia, the brain's resident macrophages, maintain brain homeostasis and respond to injury and infection. During aging they undergo functional changes, but the underlying mechanisms and their contributions to neuroprotection versus neurodegeneration are unclear. Previous studies suggested that microglia are sex dimorphic, so we compared microglial aging in mice of both sexes. RNA-sequencing of hippocampal microglia revealed more aging-associated changes in female microglia than male microglia, and more sex differences in old microglia than young microglia. Pathway analyses and subsequent validation assays revealed a stronger AKT-mTOR-HIF1α-driven shift to glycolysis among old female microglia and indicated that C3a production and detection was elevated in old microglia, especially in females. Recombinant C3a induced AKT-mTOR-HIF1α signaling and increased the glycolytic and phagocytic activity of young microglia. Single cell analyses attributed the aging-associated sex dimorphism to more abundant disease-associated microglia (DAM) in old female mice than old male mice, and evaluation of an Alzheimer's Disease mouse model revealed that the metabolic and complement changes are also apparent in the context of neurodegenerative disease and are strongest in the neuroprotective DAM2 subset. Collectively, our data implicate autocrine C3a-C3aR signaling in metabolic reprogramming of microglia to neuroprotective DAM during aging, especially in females, and also in Alzheimer's Disease.

INTRODUCTION: Telemedicine rapidly increased with the COVID-19 pandemic and could reduce cancer care disparities. Our objective was to evaluate sociodemographic (race, insurance), patient, health system, and cancer factors associated with telemedicine use in gynecologic cancers. METHODS: We conducted a retrospective cohort study of patients with endometrial cancer and epithelial ovarian cancer with at least one visit from March 2020 to October 2021, using a real-world electronic health record-derived database, representing approximately 800 sites in US academic (14%) and community practices (86%). We used multivariable Poisson regression modeling to analyze the association of ever using telemedicine with patient, sociodemographic, health system, and cancer factors. RESULTS: Of 3950 patients with ovarian cancer, 1119 (28.3%) had at least one telemedicine visit. Of 2510 patients with endometrial cancer, 720 (28.7%) had at least one telemedicine visit. At community cancer practices, patients who identified as Black were less likely to have a telemedicine visit than patients who identified as white in both ovarian and endometrial cancer (Ovarian: RR 0.62, 95% CI 0.42-0.9; Endometrial: RR 0.56, 95% CI 0.38-0.83). Patients in the Southeast, Midwest, West, and Puerto Rico were less likely to have telemedicine visits than patients in the Northeast. Uninsured patients were less likely, and patients with Medicare were more likely, to have one or more telemedicine visit than patients with private insurance. CONCLUSIONS: In this national cohort study, <30% of patients ever used telemedicine, and significant racial and regional disparities existed in utilization. Telemedicine expansion efforts should include programs to improve equity in access to telemedicine.

OBJECTIVE: To examine patient barriers and facilitators to PARP inhibitor (PARP-I) maintenance therapy in ovarian cancer. PARP-I improves survival in ovarian cancer, but these multi-year therapies cost around $100,000 annually and are under-prescribed. METHODS: We recruited patients with ovarian cancer treated with PARP-I maintenance therapy at an academic health system for a semi-structured interview. Patient demographics, including genetics and PARP-I cost, were self-reported. We assessed patient experiences with barriers and facilitators of PARP-I usage. Two team members used a thematic approach to analyze and identify key themes. RESULTS: In May 2022, we interviewed 10 patients (mean age = 65 years; 80% White; 60% with a germline genetic mutation). Patients paid on average $227.50 monthly for PARP-I, straining resources for some participants. While sampled patients were insured, all patients identified having no or inadequate insurance as a major barrier to PARP-I. At the same time, all participants prioritized clinical effectiveness over costs of care. Patients identified PARP-I delivery from specialty pharmacies, separate and different from other medications, as a potential barrier, but each had been able to navigate delivery. Patients expressed significant initial side effects of PARP-I as a potential barrier yet reported clinician communication and prompt dose reduction as facilitating continuation. CONCLUSIONS: Patients identified cost, restrictive pharmacy benefits, and initial side effects as barriers to PARP-I usage. Having insurance and a supportive care team were identified as facilitators. Enhancing communication about PARP-I cost and side effects could improve patient experience and receipt of evidence-based maintenance therapy in ovarian cancer.

OBJECTIVE: Investigate the prevalence of ERBB2/HER2 gene amplification among patients with gynecologic malignancies. METHODS: The American Association of Cancer Research (AACR) Genomics Evidence of Neoplasia Information Exchange (GENIE) (version 13.1) database was accessed and patients with endometrial, ovarian, and cervical cancer were identified. Patients with available data on the presence of copy-number gene alterations were selected for further analysis. Incidence of ERBB2 amplification following stratification by tumor site and histology was evaluated. Data from the OncoKB database, as provided by cBioPortal, was utilized to determine presence of pathogenic genomic alterations. RESULTS: A total of 6961 patients who met the inclusion criteria were identified: 49.1% with ovarian cancer, 45.2% with endometrial cancer and 5.7% with cervical cancer respectively. Overall incidence of ERBB2 amplification was 3.8%. Highest incidence of ERBB2 amplification was observed among patients with mucinous ovarian (14.4%), uterine serous (13.2%), uterine clear cell (9.4%), and uterine carcinosarcoma (7.9%). ERBB2 amplification was rare among patients with TP53 wild-type endometrioid endometrial cancer (0.4%). High incidence of mutations in genes of the PI3K pathway was observed among patients with ERBB2 amplified tumors. CONCLUSION: ERBB2 amplification is frequently encountered among patients with uterine serous carcinoma, and mucinous ovarian carcinoma. In addition, a high incidence was also observed among those with uterine clear cell carcinoma, and uterine carcinosarcoma. For patients with endometrioid endometrial carcinoma, incidence of ERBB2 amplification is low, especially in the absence of TP53 mutations.

OPINION STATEMENT: The standard of treatment for node-positive endometrial cancer (FIGO Stage IIIC) in North America has been systemic therapy with or without additional external beam radiation therapy (RT) given as pelvic or extended field RT. However, this treatment paradigm is rapidly evolving with improvements in systemic chemotherapy, the emergence of targeted therapies, and improved molecular characterization of these tumors. The biggest question facing providers regarding management of stage IIIC endometrial cancer at this time is: what is the best management strategy to use with regard to combinations of cytotoxic chemotherapy, immunotherapy, other targeted therapeutics, and radiation that will maximize clinical benefit and minimize toxicities for the best patient outcomes? While clinicians await the results of ongoing clinical trials regarding combined immunotherapy/RT as well as management based on molecular classification, we must make decisions regarding the best treatment combinations for our patients. Based on the available literature, we are offering stage IIIC patients without measurable disease postoperatively both adjuvant chemotherapy and IMRT with carboplatin, paclitaxel, and with or without pembrolizumab/dostarlimab as primary adjuvant therapy. Patients with measurable disease post operatively, high risk histologies, or stage IV disease receive chemoimmunotherapy, and vaginal brachytherapy is added for those with uterine risk factors for vaginal recurrence. In the setting of endometrioid EC recurrence more than 6 months after treatment, patients with pelvic nodal and vaginal recurrence are offered IMRT and brachytherapy without chemotherapy. For measurable recurrence not suitable for pelvic radiation alone, chemoimmunotherapy is preferred as standard of care.

Transportation is an underrecognized, but modifiable barrier to accessing cancer care, especially for clinical trials. Clinicians, insurers, and health systems can screen patients for transportation needs and link them to transportation. Direct transportation services (i.e., ride-sharing, insurance-provided transportation) have high rates of patient satisfaction and visit completion. Patient financial reimbursements provide necessary funds to counteract the effects of transportation barriers, which can lead to higher trial enrollment, especially for low socioeconomic status and racially and ethnically diverse patients. Expanding transportation interventions to more cancer patients, and addressing knowledge, service, and system gaps, can help more patients access needed cancer care.

OBJECTIVE: To evaluate the role of systematic lymphadenectomy at the time of interval cytoreductive surgery for patients with advanced-stage epithelial ovarian carcinoma who achieved complete gross resection. METHODS: The National Cancer DataBase was accessed, and patients diagnosed between 2010 and 2015 with advanced-stage ovarian carcinoma who underwent interval cytoreductive surgery and achieved complete gross resection were identified. Patients who did not undergo lymphadenectomy and those who underwent systematic lymphadenectomy (defined as at least 20 lymph nodes removed) were selected for further analysis. Median overall survival was compared with the log-rank test and controlled for a priori selected confounders. RESULTS: A total of 1060 patients were identified. Systematic lymphadenectomy was performed for 125 (11.8%) patients with a median of 29 lymph nodes (range 20-72) removed. Rate of lymph node metastasis was 62.4%. Patients who underwent systematic lymphadenectomy had higher rate of unplanned readmission (8.9% vs 1.6%, p<0.001), and median hospital stay (6 vs 4 days, p<0.001). Median overall survival for patients who did and did not undergo systematic lymphadenectomy was 44.2 and 40.4 months, respectively, p=0.40. After controlling for confounders, performance of systematic lymphadenectomy was not associated with better survival (HR=0.98, 95% CI 0.80 to 1.19). CONCLUSION: Systematic lymphadenectomy is rarely performed at the time of interval cytoreductive surgery and not associated with a survival benefit for patients who achieved complete gross resection.

BACKGROUND: Financial toxicity is associated with worse cancer outcomes, including lower survival. OBJECTIVE: To characterize the prevalence of, and patient risk factors for, financial toxicity among gynecologic oncology patients in a multi-site health system. METHODS: We identified patients seen in University of Pennsylvania gynecologic oncology practices between January 2020 and February 2022 with a patient portal account. We sent a survey to all alive patients twice between March and April 2022, including the 11-item Comprehensive Score for Financial Toxicity (COST) tool. We compared differences between patients reporting high (COST score <26) and low financial toxicity (COST score ≥26) in Χ2 and regression analyses. RESULTS: Of 8239 patients, 6925 had a portal account, and 498 completed the survey for 7.2% response rate. 44% had a COST score <26, indicating financial toxicity. Patients with high financial toxicity were more likely to be younger (mean age 54 vs 60), have cervical cancer (10% vs 4%; p=0.008), be privately insured (71% vs 57%; p=0.003) or have Medicaid (7% vs 3%; p=0.03), or be unemployed (18% vs 3%; p=<0.001), and less likely to be white (79% vs 90%, p=0.003) than those with low financial toxicity. Patients with Medicare were less likely to experience financial toxicity than privately insured patients (RR=0.59, 95% CI 0.37 to 0.95). CONCLUSION: In this study of patients with gynecologic cancer or pre-cancer, 44% had financial toxicity. Financial toxicity was higher in patients who were younger, did not identify as White, and had private insurance. Targeted measures to address financial toxicity are needed to minimize disparities in patient burden of cancer treatment.

Observational and cohort studies using large databases have made important contributions to gynecologic oncology. Knowledge of the advantages and potential limitations of commonly used databases benefits both readers and reviewers. In this review, researchers familiar with National Cancer Database (NCDB), Surveillance, Epidemiology, and End Results Program (SEER), SEER-Medicare, MarketScan, Healthcare Cost and Utilization Project (HCUP), National Surgical Quality Improvement Program (NSQIP), and Premier, describe each database, its included data, access, management, storage, highlights, and limitations. A better understanding of these commonly used datasets can help readers, reviewers, and researchers to more effectively interpret and apply study results, evaluate new research studies, and develop compelling and practice-changing research.
RESUMEN
BACKGROUND: Significant disparities exist in clinical trial participation in non-gynecologic cancers, but little is known about disparities in ovarian cancer trial participation. Our objective was to examine patient, sociodemographic (race/ethnicity, insurance), cancer, and health system factors associated with clinical trial participation in ovarian cancer. METHODS: We conducted a retrospective cohort study of patients with epithelial ovarian cancer diagnosed from 2011 to 2021, using a real-world electronic health record derived database, representing around 800 sites of care in US academic and community practices. We used multivariable Poisson regression modeling to analyze the association of ever participating in an ovarian cancer clinical drug trial with patient, sociodemographic, health system, and cancer factors. RESULTS: Of the 7540 patients with ovarian cancer, 5.0% (95% CI 4.5-5.5) ever participated in a clinical drug trial. Patients of Hispanic or Latino ethnicity were 71% less likely to participate in clinical trials (RR 0.29, 95% CI 0.13-0.61) than non-Hispanic patients, and patients whose race was unknown or other than Black or White were 40% less likely to participate in clinical trials (RR 0.68, 95% CI 0.52-0.89). Patients who had Medicaid insurance were 51% less likely (RR 0.49, 95% CI 0.28-0.87) and those with Medicare were 32% (RR 0.48-0.97) less likely to participate in clinical trials than privately-insured patients. CONCLUSION: In this national cohort study, only 5% of patients with ovarian cancer participated in clinical drug trials. Interventions are needed to decrease race, ethnicity, and insurance disparities in clinical trial participation.

OBJECTIVE: Investigate outcomes for advanced stage epithelial ovarian cancer (EOC) patients based on facility-level utilization of neoadjuvant chemotherapy (NACT). METHODS: Stage III-IV EOC patients diagnosed between 2010 and 2016 were identified in the National Cancer Database. Percentage of patients managed with NACT was calculated for facilities, reporting ≥120 patients. Facilities with lowest and highest quartile of NACT rate comprised the low and high-utilizing groups. Clinico-pathological characteristics were collected, and appropriate statistical analysis performed. RESULTS: High- and low-utilizing facilities managed on average 54.1% and 25.4% of patients with NACT respectively. Patients managed at high-utilizing facilities were significantly more likely to be >65 (p = 0.029), have stage IV disease (p < 0.001) and comorbidities (p < 0.001). Patients managed with primary debulking surgery (PDS) at low-utilizing facilities were significantly more likely to be >65, have stage IV disease, and have comorbidities (all, p < 0.001). Patients undergoing PDS at low-utilizing facilities were significantly less likely to achieve complete gross resection (p < 0.001), and were significantly more likely to experience 90-day mortality (p < 0.001), and unplanned 30-day readmission (p < 0.001). After controlling for age, comorbidities, race, insurance status, stage, grade and histology, high-utilizing facilities trended towards better overall survival (OS) (HR: 0.92, 95% CI: 0.85-0.99). Overall, patients undergoing PDS had better OS compared to those who had NACT (median 42 vs 27 months, p < 0.001). CONCLUSIONS: Despite treating an EOC population with more advanced disease and comorbidities, high-utilizing facilities have lower surgical morbidity and mortality with no detrimental impact on long-term survival. Careful patient selection to minimize the morbidity and mortality associated with PDS is pivotal.

OBJECTIVE: Prior to the COVID-19 pandemic, telehealth visits and remote clinical trial operations (such as local collection of laboratory tests or imaging studies) were underutilized in gynecologic oncology clinical trials. Current literature on these operational changes provides anecdotal experience and expert opinion with few studies describing patient-level safety data. We aimed to evaluate the safety and feasibility of telehealth and remote clinical trial operations during the COVID-19 Pandemic. METHODS: Gynecologic oncology patients enrolled and actively receiving treatment on a clinical trial at a single, academic institution during the designated pre-Telehealth and Telehealth periods were identified. Patients with at least 1 provider or research coordinator telehealth visit were included. Patient demographics, health system encounters, adverse events, and protocol deviations were collected. Pairwise comparisons were performed between the pre-Telehealth and Telehealth period with each patient serving as their own control. RESULTS: Thirty-one patients met inclusion criteria. Virtual provider visits and off-site laboratory testing increased during the Telehealth period. Delays in provider visits, imaging, and laboratory testing did not differ between time periods. Total and minor protocol deviations increased in incidence during the Telehealth period and were due to documentation of telehealth and deferment of non-therapeutic testing. Major protocol deviations, emergency department visits, admissions, and severe adverse events were of low incidence and did not differ between time periods. CONCLUSIONS: Telehealth and remote clinical trial operations appeared safe and did not compromise clinical trial protocols in a small, single institutional study. Larger scale evaluations of such trial adaptations should be performed to determine continued utility following the Pandemic.
RESUMEN
OBJECTIVE: Investigate the incidence of homologous recombination DNA damage response (HR-DDR) genomic alterations among patients with uterine sarcoma. METHODS: The American Association for Cancer Research GENIE v13.0 database was accessed and patients with uterine leiomyosarcoma, adenosarcoma, undifferentiated uterine sarcoma, high-grade endometrial stromal sarcoma, low-grade endometrial stromal sarcoma, and endometrial stromal sarcoma not otherwise specified were identified. We determined the incidence of pathogenic alterations in the following genes involved in HR-DDR: ATM, ARID1A, ATRX, BAP1, BARD1, BLM, BRCA2, BRCA1, BRIP1, CHEK2, CHEK1, FANCA, FANCC, FANCD2, FANCE, FANCF, FANCG, FANCL, MRE11, NBN, PALB2, RAD50, RAD51, RAD51B, RAD51C, RAD51D, WRN. Data from the OncoKB database, as provided by cBioPortal, was utilized to determine the presence of pathogenic genomic alterations. RESULTS: A total of 509 patients contributing with 525 samples were identified. Median patient age at sample collection was 56 years while the majority were White (80.7%). The most common histologic subtype was leiomyosarcoma (63.8%) followed by adenosarcoma (12.3%). The overall incidence of HR-DDR genomic alterations was 28.2%. The most commonly altered genes were ATRX (18.2%), BRCA2 (4%), and RAD51B (2.6%). The highest incidence of HR-DDR genomic alterations was observed among patients with leiomyosarcoma (35.4%), adenosarcoma (27%) and undifferentiated uterine sarcoma (30%), while those with low-grade endometrial stromal sarcoma had the lowest (2.9%) incidence. CONCLUSIONS: Approximately 1 in 3 patients with uterine sarcoma harbor a pathogenic alteration in HR-DDR genes. Incidence is high among patients with uterine leiomyosarcoma and adenosarcoma.
RESUMEN
OBJECTIVE: This multi-center cohort study assessed associations between race, TP53 mutations, p53 expression, and histology to investigate racial survival disparities in endometrial cancer (EC). METHODS: Black and White patients with advanced or recurrent EC with Next Generation Sequencing data in the Endometrial Cancer Molecularly Targeted Therapy Consortium database were identified. Clinicopathologic and treatment variables were summarized by race and compared. Overall survival (OS) and progression-free survival (PFS) among all patients were estimated by the Kaplan-Meier method. Cox proportional hazards models estimated the association between race, TP53 status, p53 expression, histology, and survival outcomes. RESULTS: Black patients were more likely than White patients to have TP53-mutated (N = 727, 71.7% vs 49.7%, p < 0.001) and p53-abnormal (N = 362, 71.1% vs 53.2%, p = 0.003) EC. Patients with TP53-mutated EC had worse PFS (HR 2.73 (95% CI 1.88-3.97)) and OS (HR 2.20 (95% CI 1.77-2.74)) compared to those with TP53-wildtype EC. Patients with p53-abnormal EC had worse PFS (HR 2.01 (95% CI 1.22-3.32)) and OS (HR 1.61 (95% CI 1.18-2.19)) compared to those with p53-wildtype EC. After adjusting for TP53 mutation and p53 expression, race was not associated with survival outcomes. The most frequent TP53 variants were at nucleotide positions R273 (n = 54), R248 (n = 38), and R175 (n = 23), rates of which did not differ by race. CONCLUSIONS: Black patients are more likely to have TP53-mutated and p53-abnormal EC, which are associated with worse survival outcomes than TP53- and p53-wildtype EC. The higher frequency of these subtypes among Black patients may contribute to survival disparities.

OBJECTIVE: To investigate the use and outcomes of adjuvant chemotherapy for patients with advanced-stage low-grade serous ovarian carcinoma following primary cytoreductive surgery. METHODS: Patients diagnosed between 2010 and 2015 with International Federation of Gynecology and Obstetrics stage II-IV low-grade serous ovarian carcinoma who underwent primary debulking surgery with known residual disease status and had at least 1 month of follow-up were identified in the National Cancer Database. Adjuvant chemotherapy was defined as receipt of chemotherapy within 6 months of surgery. Overall survival was evaluated using the Kaplan-Meier method and compared with the log-rank test. A Cox model was constructed to control for a priori-selected confounders. A systematic review of the literature was also performed. RESULTS: In total, 618 patients with stage II-IV low-grade serous ovarian carcinoma who underwent primary cytoreductive surgery were identified; 501 (81.1%) patients received adjuvant chemotherapy, while 117 (18.9%) patients did not. The median follow-up of the present cohort was 47.97 months. There was no difference in overall survival between patients who did and did not receive adjuvant chemotherapy (p=0.78; 4-year overall survival rates were 77.5% and 76.1%, respectively). After controlling for patient age, medical co-morbidities, disease stage, and residual disease status, administration of adjuvant chemotherapy was not associated with better overall survival (HR=0.87, 95% CI 0.55 to 1.38). Based on data from three retrospective studies, omission of adjuvant chemotherapy following cytoreductive surgery was not associated with worse progression-free survival benefit (HR=1.25, 95% CI 0.80 to 1.95) for patients with stage III-V low-grade serous ovarian carcinoma. CONCLUSIONS: Adjuvant chemotherapy may not be associated with an overall survival benefit for patients with advanced-stage low-grade serous ovarian carcinoma following primary cytoreductive surgery.

OBJECTIVE: To investigate the utilization and outcomes of adjuvant immunotherapy for patients with vulvar melanoma and inguinal lymph node metastases. METHODS: The National Cancer Database was accessed and patients with vulvar melanoma diagnosed between 2004 and 2015 who did not have distant metastases, underwent inguinal lymphadenectomy, had positive lymph nodes, and at least 1 month of follow-up were identified. Administration of immunotherapy was evaluated and clinicopathological characteristics were compared. Median overall survival was compared with the log-rank test. Stratified analysis based on clinical status of lymph nodes was performed. A Cox model was constructed to evaluate survival after controlling for confounders. RESULTS: A total of 300 patients were identified; the rate of immunotherapy use was 25% (75 patients). Patients who received immunotherapy were younger (median 58 vs 70 years, p<0.001); however, the two groups were comparable in terms of clinical lymph node status, rate of positive tumor margins, presence of tumor ulceration, tumor size, Breslow thickness, and performance of comprehensive lymphadenectomy. There was no overall survival difference between patients who did (median 31.08 months) and did not (median 22.77 months) receive immunotherapy (p=0.18). Following stratification by clinical lymph node status, immunotherapy did not improve overall survival of patients with clinically negative (median 35.35 vs 33.22, p=0.75) or positive lymph nodes (median 23.33 vs 16.99, p=0.64). After controlling for confounders, administration of immunotherapy was not associated with better overall survival (HR 0.81, 95% CI 0.57 to 1.14). CONCLUSIONS: In this study approximately one in four patients received adjuvant immunotherapy. Immunotherapy was not associated with improved overall survival.

OBJECTIVE: Our objective was to use real-world data to investigate the impact of delayed interval cytoreductive surgery on the survival of patients with advanced stage high-grade ovarian carcinoma. METHODS: We accessed the National Cancer Database and identified patients diagnosed between 2004-2015 with advanced stage high-grade ovarian carcinoma who received neoadjuvant chemotherapy and underwent interval cytoreductive surgery. Based on timing between surgery and chemotherapy administration patients were categorized into standard (9-13.0 weeks) and delayed (13.01-26 weeks) interval cytoreductive surgery groups. Overall survival was compared with the log-rank test and a Cox model was constructed to control for a priori selected confounders. RESULTS: We identified a total of 5051 patients; 2389 (47.3%) and 2662 (52.7%) in the standard and delayed interval cytoreductive surgery groups respectively. There was no difference in complete gross resection rates (53.2% vs 54.5%, p=0.51). Patients in the delayed interval cytoreductive surgery group were less likely to undergo complex surgery (39.3% vs 45.6%, p<0.001) and had lower rates of unplanned re-admission (4.1% vs 2.6%, p=0.003). There was no difference in overall survival between the standard and delayed interval cytoreductive surgery groups, p=0.13 (median 34.3 vs 33.9 months) even after controlling for confounders (hazard ratio (HR) 1.04, 95% confidence intervals (CIs): 0.97, 1.12). There was no difference in overall survival between the two groups for patients with no gross residual (p=0.95; median overall survival 40.08 vs 39.8 months) or gross residual disease (p=0.16; median overall survival 32.89 and 32.16 months). CONCLUSION: For patients with advanced stage ovarian cancer delayed interval cytoreductive surgery may not be associated with worse overall survival.
