RESUMEN
BACKGROUND: Mirvetuximab soravtansine-gynx (MIRV), a first-in-class antibody-drug conjugate targeting folate receptor α (FRα), is approved for the treatment of platinum-resistant ovarian cancer in the United States. METHODS: We conducted a phase 3, global, confirmatory, open-label, randomized, controlled trial to compare the efficacy and safety of MIRV with the investigator's choice of chemotherapy in the treatment of platinum-resistant, high-grade serous ovarian cancer. Participants who had previously received one to three lines of therapy and had high FRα tumor expression (≥75% of cells with ≥2+ staining intensity) were randomly assigned in a 1:1 ratio to receive MIRV (6 mg per kilogram of adjusted ideal body weight every 3 weeks) or chemotherapy (paclitaxel, pegylated liposomal doxorubicin, or topotecan). The primary end point was investigator-assessed progression-free survival; key secondary analytic end points included objective response, overall survival, and participant-reported outcomes. RESULTS: A total of 453 participants underwent randomization; 227 were assigned to the MIRV group and 226 to the chemotherapy group. The median progression-free survival was 5.62 months (95% confidence interval [CI], 4.34 to 5.95) with MIRV and 3.98 months (95% CI, 2.86 to 4.47) with chemotherapy (P<0.001). An objective response occurred in 42.3% of the participants in the MIRV group and in 15.9% of those in the chemotherapy group (odds ratio, 3.81; 95% CI, 2.44 to 5.94; P<0.001). Overall survival was significantly longer with MIRV than with chemotherapy (median, 16.46 months vs. 12.75 months; hazard ratio for death, 0.67; 95% CI, 0.50 to 0.89; P = 0.005). During the treatment period, fewer adverse events of grade 3 or higher occurred with MIRV than with chemotherapy (41.7% vs. 54.1%), as did serious adverse events of any grade (23.9% vs. 32.9%) and events leading to discontinuation (9.2% vs. 15.9%). CONCLUSIONS: Among participants with platinum-resistant, FRα-positive ovarian cancer, treatment with MIRV showed a significant benefit over chemotherapy with respect to progression-free and overall survival and objective response.

BACKGROUND: Mismatch-repair (MMR)/microsatellite instability (MSI) status has therapeutic implications in endometrial cancer (EC). The authors evaluated the concordance of testing and factors contributing to MMR expression heterogeneity. METHODS: Six hundred sixty-six ECs were characterized using immunohistochemistry (IHC), MSI testing, and mut-L homolog 1 (MLH1) methylation. Select samples underwent whole-transcriptome analysis and next-generation sequencing. MMR expression of metastatic/recurrent sites was evaluated. RESULTS: MSI testing identified 27.3% of cases as MSI-high (n = 182), MMR IHC identified 25.1% cases as MMR-deficient (n = 167), and 3.8% of cases (n = 25) demonstrated discordant results. A review of IHC staining explained discordant results in 18 cases, revealing subclonal loss of MLH1/Pms 1 homolog 2 (PMS2) (n = 10) and heterogeneous MMR IHC (mut-S homolog 6 [MSH6], n = 7; MLH1/PMS2, n = 1). MSH6-associated Lynch syndrome was diagnosed in three of six cases with heterogeneous expression. Subclonal or heterogeneous cases had a 38.9% recurrence rate (compared with 16.7% in complete MMR-deficient cases and 9% in MMR-proficient cases) and had abnormal MMR IHC results in all metastatic recurrent sites (n = 7). Tumors with subclonal MLH1/PMS2 demonstrated 74 differentially expressed genes (determined using digital spatial transcriptomics) when stratified by MLH1 expression, including many associated with epithelial-mesenchymal transition. CONCLUSIONS: Subclonal/heterogeneous MMR IHC cases showed epigenetic loss in 66.7%, germline mutations in 16.7%, and somatic mutations in 16.7%. MMR IHC reported as intact/deficient missed 21% of cases of Lynch syndrome. EC with subclonal/heterogeneous MMR expression demonstrated a high recurrence rate, and metastatic/recurrent sites were MMR-deficient. Transcriptional analysis indicated an increased risk for migration/metastasis, suggesting that clonal MMR deficiency may be a driver for tumor aggressiveness. Reporting MMR IHC only as intact/deficient, without reporting subclonal and heterogeneous staining, misses opportunities for biomarker-directed therapy. PLAIN LANGUAGE SUMMARY: Endometrial cancer is the most common gynecologic cancer, and 20%-40% of tumors have a defect in DNA proofreading known as mismatch-repair (MMR) deficiency. These results can be used to guide therapy. Tests for this defect can yield differing results, revealing heterogeneous (mixed) proofreading capabilities. Tumors with discordant testing results and mixed MMR findings can have germline or somatic defects in MMR genes. Cells with deficient DNA proofreading in tumors with mixed MMR findings have DNA expression profiles linked to more aggressive characteristics and cancer spread. These MMR-deficient cells may drive tumor behavior and the risk of spreading cancer.

INTRODUCTION: Racial and ethnic disparities in gynecologic cancer care have been documented. Treatment at academic facilities is associated with improved survival, yet no study has examined independent associations between race and ethnicity with facility type among gynecologic cancer patients. MATERIALS & METHODS: We used the National Cancer Database and identified 484,455 gynecologic cancer (cervix, ovarian, uterine) patients diagnosed between 2004 and 2020. Facility type was dichotomized as academic vs. non-academic, and we used logistic regression to estimate multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) between race and ethnicity and facility type. Secondarily, we examined joint effects of race and ethnicity and facility type on overall survival using Cox proportional hazards regression. RESULTS: We observed higher odds of treatment at academic (vs. non-academic) facilities among American Indian/Alaska Native (OR = 1.42, 95% CI = 1.28-1.57), Asian (OR = 1.64, 95% CI = 1.59-1.70), Black (OR = 1.69, 95% CI = 1.65-1.72), Hispanic (OR = 1.70, 95% CI = 1.66-1.75), Native Hawaiian/Pacific Islander (OR = 1.74, 95% CI = 1.57-1.93), and other race (OR = 1.29, 95% CI = 1.20-1.40) patients compared with White patients. In the joint effects survival analysis with White, academic facility-treated patients as the reference group, Asian, Hispanic, and other race patients treated at academic or non-academic facilities had improved overall survival. Conversely, Black patients treated at academic facilities [Hazard Ratio (HR) = 1.10, 95% CI = 1.07-1.12] or non-academic facilities (HR = 1.19, 95% CI = 1.16-1.21) had worse survival. DISCUSSION: Minoritized gynecologic cancer patients were more likely than White patients to receive treatment at academic facilities. Importantly, survival outcomes among patients receiving care at academic institutions differed by race, requiring research to investigate intra-facility survival disparities.
RESUMEN
OBJECTIVES: The use of a platinum doublet for the treatment of platinum-sensitive epithelial ovarian cancer (EOC) recurrence is well established. The impact of the nonplatinum chemotherapy used as part of a platinum doublet on PARP inhibitor (PARPi) and platinum sensitivity it not known. We aimed to describe oncologic outcomes in cases of recurrent EOC receiving PARPi as maintenance therapy based on preceding platinum doublet. METHODS: Retrospective study of patients with platinum-sensitive recurrent ovarian, fallopian tube or primary peritoneal cancer treated with platinum doublet followed by maintenance PARPi from 1/1/2015 and 1/1/2022. Comparisons were made between patients receiving carboplatin + pegylated liposomal doxorubicin (CD) versus other platinum doublets (OPDs). Descriptive statistics, Kaplan-Meier and univariate survival analyses were performed. RESULTS: 100 patients received PARPi maintenance following a platinum doublet chemotherapy regimen for platinum-sensitive recurrence. 25/100 (25%) received CD and 75/100 (75%) received OPDs. Comparing CD and OPDs, median progression-free survival was 8 versus 7 months (p = 0.26), median time to platinum resistance was 15 versus 13 months (p = 0.54), median OS was 64 versus 90 months (p = 0.28), and median OS from starting PARPi was 25 versus 26 months (p = 0.90), respectively. CONCLUSIONS: Using pegylated liposomal doxorubicin as part of a platinum doublet preceding maintenance PARPi for platinum-sensitive recurrence does not seem to hasten PARPi resistance or platinum resistance compared to OPDs. Although there was a non-significant trend towards increased OS among patients who received a platinum doublet other than CD prior to PARPi, the OS from PARPi start was similar between groups. Given the retrospective nature of this study and small study population, further research is needed to evaluate if the choice of platinum doublet preceding PARPi maintenance impacts PARPi resistance, platinum resistance and survival.

OBJECTIVE: Investigate racial disparities in outcomes and molecular features in Black and White patients with endometrioid endometrial carcinoma (EEC). METHODS: Black and White patients diagnosed with EEC who underwent hysterectomy ± adjuvant treatment in SEER, National Cancer Database (NCDB), the Genomics Evidence Neoplasia Information Exchange (GENIE) project (v.13.0), and eight NCI-sponsored randomized phase III clinical trials (RCTs) were studied. Hazard ratio (HR) and 95% confidence interval (CI) were estimated for cancer-related death (CRD), non-cancer death (NCD), and all-cause death. RESULTS: Black (n = 4397) vs. White (n = 47,959) patients in SEER had a HR (95% CI) of 2.04 (1.87-2.23) for CRD and 1.22 (1.09-1.36) for NCD. In NCDB, the HR (95% CI) for death in Black (n = 13,468) vs. White (n = 155,706) patients was 1.52 (1.46-1.58) dropping to 1.29 (1.23-1.36) after propensity-score matching for age, comorbidity, income, insurance, grade, stage, LVSI, and treatment. In GENIE, Black (n = 109) vs. White (n = 1780) patients had fewer PTEN, PIK3R1, FBXW7, NF1, mTOR, CCND1, and PI3K-pathway-related gene mutations. In contrast, TP53 and DNA-repair-related gene mutation frequency as well as tumor mutational burden-high status were similar in Black and White patients. In RCTs, Black (n = 187) vs. White (n = 2877) patients were more likely to have advanced or recurrent disease, higher grade, worse performance status and progressive disease. Risk of death in Black vs. White patients in RCTs was 2.19 (1.77-2.71) persisting to 1.32 (1.09-1.61) after matching for grade, stage, and treatment arm while balancing age and performance status. CONCLUSIONS: Differences exist in clinical presentation, outcomes, and molecular features in Black vs. White patients with EEC in real-world registries and RCTs. Targeted-drug development, strategies to modify social determinants, and diverse inclusion in RCTs are approaches to reduce disparities.

OBJECTIVE: We sought to provide a contemporary report on stage IVB endometrial carcinoma (2009 FIGO criteria) and applied the 2023 FIGO staging criteria to this population. METHODS: Retrospective review of patients who underwent cytoreduction for stage IVB endometrial carcinoma (2009 FIGO criteria) from 2014 to 2020 was performed. Demographics, clinicopathologic factors, and outcomes were recorded. Disease burden and distribution were determined by imaging, operative notes, and pathology reports. Patients were re-staged according to 2023 FIGO staging criteria. Categorical variables were compared using χ2 or Fisher's exact test, and Kaplan-Meier curves compared survival outcomes using the log-rank test. RESULTS: Eighty-eight cases were included. Most patients (63.6%) were not suspected to have stage IVB (2009 FIGO criteria) disease prior to surgery. Seventy-two percent of patients underwent primary cytoreduction, and 12 (19%) were suboptimal. Median progression-free survival (PFS) was 12 months (95% CI 10-16 months), and median overall survival (OS) was 38 months (95% CI 19-61 months). Degree of cytoreduction (p = 0.0101) and pelvic-confined metastatic disease (p = 0.0149) were significant prognostic factors, while distant metastases were not associated with worse outcomes. For those patients who underwent primary cytoreduction, number (p = 0.0453) and diameter (p = 0.0192) of tumor deposits were associated with PFS. When 2023 FIGO staging criteria were applied, 58% of patients underwent change in stage, and 8% did not meet criteria for complete staging. PFS was significantly different based on 2023 FIGO staging (p = 0.0307); a trend in OS was also noted (p = 0.0550). CONCLUSION: Stage IVB endometrial carcinoma (2009 FIGO criteria) encompasses a diverse cohort of patients, where certain clinicopathologic features, tumor burden, and degree of cytoreduction are associated with outcomes. The 2023 FIGO staging criteria significantly improves our ability to risk-stratify patients.

OBJECTIVE: To determine the prevalence of Type 2 diabetes mellitus (T2DM) diagnoses during the peri-operative and survivorship periods in patients following surgical management of endometrial cancer (EC). METHODS: An IRB-approved, retrospective single-institution cohort study was performed in patients who underwent surgical management of EC from 2014 to 2020. The perioperative period was defined as the 30 days before and after surgery. T2DM diagnoses occurring during survivorship were recorded. T2DM diagnoses were defined by a HgbA1c ≥6.5% or a random blood glucose ≥200 mg/dL. Sequelae of peri-operative T2DM and predictors of future T2DM were examined utilizing univariate analysis. RESULTS: Of 519 patients meeting inclusion criteria, 37 (7.1%) were diagnosed with T2DM in the perioperative period. Patients diagnosed with T2DM in the perioperative period had significantly higher BMI (p = 0.006) compared to no T2DM, but there were no significant differences in age (p = 0.20), ethnicity/race (p > 0.05) or ECOG score (p = 0.19). The rates of intraoperative complications between groups did not significantly differ, except for vascular complications (p = 0.005), and the incidence of any postoperative complication was higher in the perioperative T2DM group (p = 0.01). With a median follow-up of 29 months [range 11.6-49.0 months], an additional 18.3% (n = 88) of the cohort met diagnostic criteria for T2DM. BMI (p < 0.001), perioperative glucose (p < 0.001), and HgbA1c (p = 0.002) demonstrate risk for a T2DM diagnosis during survivorship. CONCLUSION(S): In this retrospective cohort of EC patients, 25.4% were diagnosed with T2DM, with the majority diagnosed in the survivorship period. Surgical management and subsequent surveillance of EC presents an opportunity to diagnose at-risk patients with T2DM.
RESUMEN
OBJECTIVE: We sought to assess the impact of antibiotic (ABX) and proton-pump inhibitor (PPI) use on progression-free (PFS) and overall survival (OS) in patients treated with adjuvant platinum-based chemotherapy (PC) for endometrial cancer (EC). METHODS: A retrospective, single-institution cohort study of EC patients treated with ≥four cycles of adjuvant PC following surgical staging from 2014 to 2020. Demographics and clinicopathologic features, including ABX and PPI use, were compared using χ2 and Fisher's exact tests. Univariate and multivariable analyses were performed, and survival outcomes were compared using the log-rank test. RESULTS: Of 325 patients, 95 (29%) received ABX, and 80 (24.6%) received PPI. ABX were associated with decreased 3-year PFS (49.9% vs. 66%; p = 0.0237) but not 3-year OS (68.9% vs. 79.9%; p = 0.0649). ABX targeting gram-positive bacteria were associated with decreased 3-year PFS (21.2% vs. 66.0% vs. 55.4%; p = 0.0038) and 3-year OS (36.5% vs. 79.9% vs. 75.6%; p = 0.0014) compared to no ABX and other ABX, respectively. PPI use was associated with decreased 3-year PFS (46.9% vs. 66.0%; p = 0.0001) and 3-year OS (60.7% vs. 81.9%; p = 0.0041) compared to no PPI. On multivariable regression analysis controlling for confounders including stage, histology, grade, radiation, and co-morbidities, PPI use was independently associated with worse PFS (HR 1.96, 95% CI 1.25-3.08; p = 0.0041) and OS (HR 2.06, 95% CI 1.01-4.18, p = 0.04). CONCLUSION: In this retrospective cohort study, we demonstrate that PPI use is independently associated with worse PFS and OS in patients with EC treated with PC. ABX use was associated with worse PFS on univariate analysis only. There is an unmet need to understand how PPI, ABX, and, potentially, the microbiome impact the effectiveness of chemotherapy in EC patients.

OBJECTIVES: To describe stage, treatment patterns, and survival for glassy cell carcinoma of the cervix (GCCC), a poorly understood rare tumor. METHODS: Clinical data and survival were compared between GCCC and more common histologic types using the National Cancer Database (NCDB) from 2004 to 2017. A retrospective review of GCCC cases at our institution from 2012 to 2020 was simultaneously performed with staging updated according to 2018 FIGO staging. Descriptive statistics and survival analyses were performed, and outcomes compared to historical references. RESULTS: 143/89,001 (0.16%) NCDB cervical cancer cases were GCCC. Compared to other histologies, GCCC cases were younger, with 74.8% diagnosed before age 50. Stage distribution was similar. Stage I cases were less commonly treated with surgery alone (19/69, 27%). 79.4% of locally advanced (stage II-IVA) cases were treated with definitive chemoradiation. GCCC demonstrated worse OS for early-stage and locally-advanced disease. No survival differences were observed for patients with stage IVB disease. Our institutional review identified 14 GCCC cases. Median age at diagnosis was 34 years. All nine early-stage cases underwent radical hysterectomy. Adjuvant radiation was given for cases meeting Sedlis criteria (4/9, 44%). All five advanced stage cases were stage IIIC and received definitive chemoradiation. Recurrence rate was 0% (0/9) for early-stage and 60% (3/5) for advanced-stage cases. 3-year PFS was 100% for early-stage and 40% for advanced-stage. 3-year OS was 100% for early-stage and 60% for advanced-stage GCCC. CONCLUSIONS: GCCC presents at earlier ages than other cervical cancer histologic types. Although NCDB showed worse OS, our more contemporary institutional review, which incorporates updated staging and newer treatment modalities found outcomes more similar to historical references of more common histologic subtypes.

OBJECTIVES: To determine whether morbid obesity should serve as an independent factor in the decision for same day discharge following minimally invasive hysterectomy. METHODS: Retrospective review was performed of patients with BMI ≥ 40 who underwent minimally invasive hysterectomy within a single comprehensive cancer center between January 2018 - August 2020. Demographics, perioperative factors, post-operative monitoring, complications, and readmissions were compared between patients who underwent same day discharge and overnight observation using Fisher's exact tests and Wilcoxon rank-sum tests. RESULTS: 374 patients with BMI ≥ 40 were included. Eighty-three (22.2%) patients underwent same day discharge, and 291 (77.8%) patients underwent overnight observation. Factors associated with increased likelihood of same day discharge included younger age (median age 53 vs 58; p = 0.001), lower BMI (median BMI 45 vs 47; p = 0.005), and fewer medical co-morbidities (Charlson Co-Morbidity Index 2 vs 3; p < 0.001). On multivariate regression analysis, frailty (OR 2.16 [1.14-4.11], p = 0.019) and surgical completion time after 12 PM (OR 3.67 [2.16-6.24], p < 0.001) were associated with increased risk of overnight observation. Few patients admitted for routine overnight observation required medical intervention (n = 14, 4.8%); most of these patients were frail (64.3%). The overall hospital readmission rate within 30 days of discharge was 3.2% (n = 12), with no patients discharged on the day of surgery being readmitted. CONCLUSIONS: Morbid obesity alone should not serve as a contraindication to same day discharge following minimally invasive hysterectomy. Admission for observation was associated with low rates of clinically meaningful intervention, and patients who underwent same day discharge were not at increased risk of adverse outcome.

BACKGROUND: Uterine cancers are associated with a high risk for venous thromboembolisms. The American Society of Clinical Oncology practice guidelines recommend that all patients undergoing pelvic surgery for cancer should receive extended pharmacologic thromboprophylaxis with the duration being dependent on risk. However, risk stratification for patients with uterine cancer is not clearly defined. The Caprini score is the most widely used risk assessment model but it has been found to have limited use in the gynecologic oncology population. A modified Caprini score has been explored in other populations. The Khorana score is an additional risk assessment model that has not been studied in this context. OBJECTIVE: Our objective was to evaluate the ability of a modified Caprini model and the Khorana score to risk stratify patients with uterine cancer for postoperative venous thromboembolisms within 90 days of surgery. STUDY DESIGN: Following institutional review board approval, a retrospective cohort study was performed, and all patients with uterine cancer who underwent a hysterectomy over a 4-year period were included. The Caprini and Khorana scores were calculated for each patient. The Caprini score cutoff for highest risk was evaluated at ≥7, ≥8, and ≥9 (modified Caprini) and the Khorana score cutoff was evaluated at ≥2 and ≥3. To determine the prognostic use of each score and other clinico-pathologic criteria related to the development of a venous thromboembolism, univariate analyses were performed using independent t tests, chi-square tests, or Fisher's exact tests; a multivariate analysis was performed using logistic regression. RESULTS: A total of 954 patients were included. The rate of venous thromboembolism development was 1.7% (16/954). A minimally invasive surgical approach was used in 90.5% (863/954) of patients. The mean Caprini score for patients with a venous thromboembolism was 10.3 compared with 8.1 for patients without a venous thromboembolism (95% confidence interval, 1.17-3.33; P<.0001). The mean Khorana score for the venous thromboembolism group was 2.4 vs 1.9 for those without (95% confidence interval, 0.04-0.82; P=.03). Both the Caprini and Khorana scores were found to be associated with venous thromboembolisms, but only a Caprini score with a cutoff of ≥8 or ≥9 was statistically significant (risk ratio, 31.25; 95% confidence interval, 1.88-519.49; risk ratio, 4.59; 95% confidence interval, 1.49-14.13, respectively), with high accuracy based on the area under the curve (0.75 and 0.68, respectively). Of the minimally invasive subgroup, 11.7% (101/863) of patients had same-day discharge with no postoperative thromboprophylaxis; none of these patients developed venous thromboembolisms. Despite extended prophylaxis among the laparotomy patients (30 days), the rate of venous thromboembolisms was more than 3 times that of the minimally invasive group (5.49% vs 1.7%). Advanced tumor stage and leukocytosis were noted to be independent risk factors for venous thromboembolisms. CONCLUSION: Our study suggests that using a modified Caprini score could help to identify the highest-risk patients who would benefit from prolonged thromboprophylaxis, could reduce the incidence of postoperative venous thromboembolisms, and could minimize the cost and harm of overtreatment. These findings need to be validated in a prospective manner, and further research is needed to determine the optimal duration of therapy.

BACKGROUND: With the increasing rates of same-day discharge following minimally invasive surgery for endometrial cancer, the need for and value of routine postoperative testing is unclear. OBJECTIVE: This study aimed to determine whether routine postoperative laboratory testing following minimally invasive hysterectomy for endometrial cancer leads to clinically significant changes in postoperative care. STUDY DESIGN: This was a single-institution retrospective cohort study of patients undergoing minimally invasive hysterectomy for endometrial cancer by a gynecologic oncologist between June 2014 and June 2017. Patient demographics, preoperative comorbidities, operative and postoperative data, and pathologic findings were manually extracted from the patients' medical records. The financial burden of laboratory testing was computed using hospital-level cost data. RESULTS: Of the 649 women included in the analysis, most (91.4%) were White, with a mean age of 61 years, and mean body mass index of 38.0 kg/m2. The most common comorbidities were diabetes mellitus (31.9%, n=207), chronic pulmonary disease (7.9%, n=51), and congestive heart failure (3.2%, n=21). Median operative time was 151 minutes (range, 61-278), and median estimated blood loss was 100 mL (range, 10-1500). Most patients (68.6%, n=445) underwent lymphadenectomy. All patients had postoperative laboratory tests ordered: 100% complete blood count, 99.7% chemistry, 62.9% magnesium, 46.8% phosphate, 37.4% calcium, and 1.2% liver function tests. Twenty-six patients (4.0%) had a change in management owing to postoperative laboratory test results. Of these 26 women, 88% experienced a change in clinical status that would have otherwise prompted testing. Only 3 (0.5% of entire cohort) were asymptomatic: 1 received a blood transfusion for asymptomatic anemia, and the other 2, who did not carry a diagnosis of diabetes mellitus, had interventions for hyperglycemia. On univariable analysis, peripheral and cerebrovascular disease, diabetes mellitus with end-organ damage, and a Charlson Comorbidity Index of ≥3 were associated with increased odds of change in management; these were not significant on multivariable analysis. Routine postoperative laboratory evaluation in this cohort increased hospital costs by $292,000. CONCLUSION: Routine postoperative laboratory tests are unlikely to lead to significant changes in management for women undergoing minimally invasive hysterectomy for endometrial cancer, and may increase cost without providing a discernible clinical benefit. In the setting of strict postoperative guidelines, laboratory tests should be ordered when clinically indicated rather than as part of routine postoperative management for women undergoing minimally invasive hysterectomy for endometrial cancer.

PURPOSE: Endometrial cancer (EC) is the most common gynecological cancer among women in the United States. Despite well-documented racial/ethnic disparities in EC incidence and mortality rates, limited data exist regarding disparities in hysterectomy surgical outcomes. We evaluated associations of race/ethnicity with postoperative complications, serious adverse events (SAEs), and length of hospital stay among women undergoing EC-related hysterectomy. METHODS: Using National Surgical Quality Improvement Program (NSQIP) data, we identified women (≥18 years) undergoing hysterectomy to treat EC between 2014 and 2020. We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations of race/ethnicity (white, black, and Latina) with postoperative complications and SAEs. We used Poisson regression with robust standard errors to calculate incidence rate ratios (IRRs) and 95% CIs for the association of race/ethnicity with length of hospital stay. RESULTS: Of 22,778 women undergoing EC-related hysterectomy, 3.1% developed postoperative complications. Black (adjusted OR: 1.62; 95% CI 1.05-2.48) and Latina women (adjusted OR: 1.79; 95% CI 1.04-3.09) had higher postoperative complication risks than white women. The overall SAE incidence was 5.0%. Black women (adjusted OR: 1.55, 95% CI 1.13-2.15) had higher SAE risks than white women. Length of hospital stay was significantly longer for black women than white women (IRR: 1.18; 95% CI 1.07-1.30). CONCLUSIONS: We observed racial/ethnic disparities in EC-related hysterectomy surgical outcomes in a large, diverse sample of U.S. women between 2014 and 2020. Studies to elucidate the underlying mechanisms of these racial disparities, with a focus on social context remain necessary.

OBJECTIVE: To determine the feasibility of hospital-based genetic counseling and testing (GC/T) Traceback for Ovarian Cancer (OC) patients, as proposed by the Division of Cancer Prevention and the Division of Cancer Control and Population Sciences, National Cancer Institute. METHODS: Living patients with OC were sent a letter explaining the availability of guideline-supported GC/T for at least BRCA1/2 and surrogates of deceased patients were called on the telephone. Outcomes of contact attempts were systematically recorded and statistically described. RESULTS: 598 Traceback-eligible OC patients diagnosed from 2006 to 2016 were identified (163 presumed-living and 435 deceased). Two living patients called our office and scheduled an appointment for GC/T after receiving a letter. For surrogates of prior patients, successful contact occurred in 25% of call attempts. Fourteen individuals (2 living patients and 12 surrogates) underwent genetic counseling. Of those 14, 10 individuals consented to genetic testing and 5 followed through with sample collection. None of these individuals had pathogenic variants (PVs). When surrogate call notes were reviewed, 58% reflected positive responses to contact, however 42% were noted to have negative or indifferent responses, which were most common among spouses. Total time spent for hospital-based Traceback was 109 h. CONCLUSIONS: Overall, hospital-based Traceback via letter and telephone contact of surrogates is time-intensive and results in minimal uptake of GC/T. To practically execute this type of outreach program, health systems should consider collection of alternative contact information to allow for electronic communication of patient surrogates. Our study also underscores the importance of timely GC/T while patients are in active cancer care.

OBJECTIVE: Most women diagnosed with endometrial cancer undergo primary surgical management with hysterectomy. Although racial disparities in readmission risk following hysterectomy for non-cancerous conditions have been reported, data among women with endometrial cancer are absent. This study evaluates racial differences in readmission risk among women undergoing endometrial cancer-related hysterectomy. METHODS: In the National Cancer Database, women who underwent surgical management for endometrial cancer from 2004 to 2018 were identified. Readmission and minimally invasive hysterectomy (MIH) proportions were plotted according to year of diagnosis and race/ethnicity. Multivariable logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between readmission risk and epidemiological, facility, tumor, and surgical characteristics. A base model was sequentially adjusted to incorporate significant covariates. RESULTS: There were 350,631 patients included in the study. The proportion of MIH increased among all race/ethnicities over the study period; however, MIH rates were lower among Black women. Readmission proportions were 2.7% among White, 4.2% among Black, 2.9% among Hispanic, 2.4% among Asian, 2.1% among American Indian/Alaska Native, and 3.1% among Native Hawaiian/Pacific Islander women. In the fully adjusted model incorporating surgical approach, Black women (OR: 1.20, 95% CI = 1.13, 1.28) and Native Hawaiian/Pacific Islander women (OR: 1.54, 95% CI = 1.09, 2.18) were more commonly readmitted compared to White women. CONCLUSIONS: In this study, Black and Native Hawaiian/Pacific Islander women with endometrial cancer had significantly higher readmission risk than White women. Optimizing perioperative care for minority women is an essential component of overcoming racially disparate endometrial cancer outcomes.

OBJECTIVE: To examine patients with confirmed endometrial cancer recurrence; evaluate patterns, presentation, and mode of diagnosis. STUDY DESIGN: A retrospective review of women with endometrial cancer diagnosis between 2014 and 2020. Disease recurrences were evaluated. Medical records were reviewed focusing on presentation at time of recurrence. Relationships were assessed using χ2, Fisher's exact test, t-test, and Wilcoxon test. The Kaplan-Meier product limit was used to estimate survival. Multiple logistic regression analysis was used to assess the impact of covariates. RESULTS: Endometrial cancer recurrence was identified in 201 (11.7%) patients. Sixty percent (120/201) of patients presented with symptoms. Pain was the most common presenting symptom (23.4%, 47/201) and bleeding was reported in <14% (28/201). Patients with symptomatic presentation were less likely to be able to receive treatment for their recurrent disease (76.7% vs 91.3%, p = 0.005). Asymptomatic pelvic exam diagnosed recurrence in 13.4% (27/201) and was more common in patients initially diagnosed with early-stage disease (66.7% vs 34.5% p = 0.001) of endometrioid histology (66.7% vs 36.8%, p = 0.003) without prior adjuvant therapy (48.2% vs 17.9%, p = 0.001). More than1/3 of diagnoses were made by providers outside of the oncologic care team. CONCLUSION: The majority of women with recurrent endometrial cancer were symptomatic and pain is a common complaint associated with disease recurrence. Patients with symptomatic presentation of disease recurrence were less likely to receive treatment for recurrent disease but this did not result in an overall survival (OS) difference. Given the rising mortality rate of endometrial cancer further work is needed to develop multidisciplinary surveillance strategies that will enable meaningful treatment of disease recurrence.

BACKGROUND: Endometrial cancer (EC) is the most common gynecologic cancer in the U.S. The objective of this cohort study was to characterize the clinical and pathologic features that are associated with endometrial cancer-specific death for women cared for at a single National Cancer Institute-designated comprehensive cancer center. PATIENTS, MATERIALS, AND METHODS: This is a retrospective cohort from 2014 to 2017 including all women who had a hysterectomy for EC. Charts were reviewed for clinical and pathologic data, focusing on survival outcomes. RESULTS: Seven hundred seventy-one patients with EC underwent hysterectomy with 760 informative for outcomes. Seventy-six (10%) deaths were related to their EC; 62 women died from recurrent EC. Nonendometrioid histology and advanced stage were predictors of recurrence and EC death. Among patients with endometrioid ECs, mismatch repair status was significantly associated with EC-specific survival (relative risk = 4.8; 95% confidence interval, 2.3-10.3; p < .0001). Most patients with EC who recurred died of their disease 62/83 (74.7%). Nearly half of the patients that recurred (27/62) had no additional therapy at the time of recurrence. Overall survival was significantly longer for those women who had additional treatment at the time of recurrence; however, the improvement in overall survival with therapy at recurrence was largely attributable to effects in those women who were adjuvant therapy naïve. CONCLUSION: Although there is benefit of treatment at the time of recurrence for treatment-naïve women; only approximately half of patients were able to receive therapy. There is an urgent need for continued efforts for more effective EC therapy in both the front-line and recurrent setting as well as early identification of cancer diagnosis and recurrence. IMPLICATIONS FOR PRACTICE: Approximately 10% of patients died of their endometrial cancer. Most deaths were from recurrent disease; however, almost 20% of endometrial cancer deaths were within 120 days of surgery. Although treatment at the time of recurrence improves overall survival, only approximately half of patients will receive therapy at the time of recurrence. Traditional prognostic features like histology and stage remain important to predict risk of recurrence, and newer biomarkers, such as mismatch repair status, may improve risk stratification and targeted therapy. There remains an urgent need for improved therapy and early detection of diagnosis and recurrence.

PURPOSE OF REVIEW: This article will discuss the recent data on the prognostic significance of molecular classification of endometrial carcinoma, as well as its impact on directing treatment decisions. RECENT FINDINGS: Molecular classification has emerged as a complement to the current paradigm of endometrial cancer (EC) risk stratification. POLE mutations appear to portend favorable prognoses, but data are insufficient to indicate withholding treatment based on this signature. Copy number high (CNH) EC carries a worse prognosis and may benefit from more aggressive therapy. MMRd tumors are likely to have other prognostic features that indicate adjuvant treatment and many recurrences respond favorably to pembrolizumab. Progression of molecular profiling may allow further discrimination of the no specific molecular profile (NSMP) group. Treatment for this group remains largely based on conventional risk factors. For both the NSMP and the CNH groups, treatment with lenvatinib and pembrolizumab is an attractive contemporary option for recurrence management. Molecular classification is a useful adjunct to conventional risk stratification paradigms for both prognostic counseling and treatment selection. Clinical trials incorporating molecular signatures in assigning treatment strategies may further elucidate the value of this classification system.

OBJECTIVE: To determine associations between adoption of Medicaid expansion (ME) and changes in insurance status, early stage diagnosis, and cancer survival among women with endometrial carcinoma (EC). METHODS: The National Cancer Database (NCDB) was queried for patients diagnosed with EC between the age 40-64 from 2004 to 2015. Difference-in-differences analysis quantified the impact of ME on the proportion of new EC diagnoses with insurance (vs. uninsured), the proportion diagnosed with stage I (vs. II-IV), and overall survival. RESULTS: 156,253 patients were included. Among 65,019 women living in ME states, ME is associated with an increase in the percent of EC cases who are insured of 1.4% (95% CI 0.9-2.0%, p < 0.0001), with strongest effects among Hispanic women, women in the lowest income quartile, and women in the second age quartile (age 53-57). There was no overall impact of ME on stage, though an increase of early stage diagnoses by 2.4% (95% CI 0.3-4.5%, p = 0.022) was observed among women age 53-57. There was a trend towards improved overall survival with ME, which was strongest in women age 53-57 (HR = 0.83, 95% CI 0.70-0.99, p = 0.037). CONCLUSIONS: Among women with EC, ME positively impacted insurance coverage, an important hurdle in accessing health care. In women aged 53-57, ME was associated with earlier stage at diagnosis and improved survival, suggesting that the magnitude of the improvement in insurance coverage may correlate with important clinical outcomes. Efforts should continue to understand the complexity of barriers to health care access and to develop effective strategies to surmount them.

BACKGROUND: The objective of this study was to assess the correlation between mismatch repair (MMR) status, disease recurrence patterns, and recurrence-free survival (RFS) in patients with high-intermediate-risk (HIR) endometrioid endometrial cancer (EEC). METHODS: A single-institution chart review for consecutive patients who were diagnosed with ECC between 2007 and 2016 was undertaken. Tumor MMR status was determined for all patients based on reported findings for mutL homolog 1 (MLH1), postmeiotic segregation (PMS2), mutS homolog 2 (MSH2), and MSH6 immunohistochemistry; and defective MMR (dMMR) status was defined as the lack of expression of at least 1 of these proteins. Patients were classified with HIR EEC according to criteria used for Gynecologic Oncology Group study 249. The factors associated with recurrence were assessed by logistic regression. RFS and associated factors were assessed by Kaplan-Meier survival analysis and Cox proportional-hazards models. RESULTS: In total, 197 patients who had HIR EEC (64 with dMMR and 133 with intact MMR [iMMR]) were identified, of whom 32 (16.2%) developed recurrent disease. The median follow-up was 54 months. The recurrence rate for women who had dMMR was 28% compared with 10.5% for those who had iMMR (P = .002), independent of the type of adjuvant therapy they received. The increase in distant recurrences among patients who had dMMR was even more pronounced (14.1% vs 3%; P = .003). The estimated 5-year RFS was 66% for women who had dMMR compared with 89% for those who had iMMR (P = .001). Excluding isolated vaginal recurrences, the difference in 5-year RFS was 73.5% versus 95%, respectively (P = .0004). CONCLUSIONS: Patients who had HIR EEC with dMMR had increased rates of recurrence and decreased RFS compared with those who had HIR EEC with iMMR, despite the receipt of similar adjuvant treatment. The current findings highlight the need for alternative treatment options and the importance of MMR status as a biomarker for patients with HIR EEC.
