PD-L1 is expressed in a significant proportion of EC and is associated with mismatch repair deficiency, potentially representing a mechanism of tumor immune evasion and a therapeutic target in EC.

Study Objective: Operative hysteroscopy requires elevated intrauterine pressures, which could lead to the spread of malignant cells into the peritoneal cavity. Currently, there is a paucity of data analyzing clinical outcomes in endometrial cancer after hysteroscopic morcellation with newer equipment. In this study, we sought to determine whether there are increased rates of positive peritoneal cytology, lymphovascular space invasion, or surgical upstaging in patients undergoing hysteroscopic morcellation compared with alternative endometrial biopsy methods. Design: A retrospective chart review of patients from 2013−2018 was performed. The exclusion criteria included biopsy at outside institution, stage IV endometrial cancer known before biopsy, and missing data regarding biopsy method and histology. Peritoneal cytology results, lymphovascular space invasion, and surgical staging were compared by method of biopsy and histology using chi-square and Kruskal-Wallis tests. Setting: The patients included in this study were accrued from the Karmanos Cancer Insittute in Detroit, Michigan. Patients: A total of 289 patients met the inclusion criteria: 184 patients were classified as low-grade (F ed eration Internationale de Gyn ecologie et d'Obst etrique grades 1 and 2) and 105 as high-grade (F ed eration Internationale de Gyn ecologie et d'Obst etrique grade 3, serous, clear cell, and carcinosarcoma) endometrial cancer. Interventions: Fifty-three patients (18%) underwent hysteroscopy with morcellation. Alternative biopsy methods included hysteroscopy without morcellation, n = 81 (28%); endometrial biopsy, n = 112 (38.7%); and dilation and curettage, n = 43 (15%). Measurements and Main Results: Positive peritoneal cytology was noted in 34 cases (12%) and negative cytology in 165 (57%). Cytology was not performed in 90 cases (31%). When comparing outcomes by histologic subtypes, no difference was seen in peritoneal cytology (p = .704 and .727 for low grade and high grade, respectively), stage (p = .773 and .053 for low grade and high grade, respectively) or lymphovascular space invasion (p = .400 and .142 for low grade and high grade, respectively). Conclusion:Our study demonstrates that hysteroscopy with morcellation is a safe diagnostic method for low-and highgrade endometrial pathologic conditions and does not lead to increased dissemination of malignant cells, lymphovascular space invasion, or upstaging of patients.

ObjectivePelvic floor dysfunction is a common adverse effect of uterine cancer treatment. In this study we compared patient-reported outcomes regarding pelvic floor dysfunction among uterine cancer survivors after hysterectomy and bilateral salpingo-oophorectomy, surgery and brachytherapy, or surgery and external beam radiotherapy with or without brachytherapy versus women who had a hysterectomy for benign indications.MethodsWe used the validated 20-item Pelvic Floor Distress Inventory to assess lower urinary distress, colorectal distress, and pelvic organ prolapse dysfunction in each treatment group. Pelvic floor dysfunction-related quality of life in these domains was compared across treatment modalities using the Pelvic Floor Impact Questionnaire-7. Treatment type, body mass index, comorbidities, and number of vaginal births were obtained from medical records. A zero-inflated negative binomial regression model was used to assess the association of treatment regimens and covariates relative to the non-cancer cohort.ResultsA total of 309 surveys were analyzed. The median age of the patients at surgery was 58 years (range 20–87) and the median age at survey completion was 66 years (range 34–92). Most participants reported experiencing at least one symptom of pelvic floor dysfunction (76% by Pelvic Floor Distress Inventory-2). The type of treatment had no effect on overall pelvic floor dysfunction on multivariate analysis (all p>0.05). Worse urinary-related symptoms were associated with higher body mass index at surgery (OR 1.41), higher age at time of survey (OR 1.07), and higher numbers of vaginal births (OR 1.43) (all p<0.05).ConclusionsOverall, pelvic floor dysfunction did not significantly vary by treatment modality. Our findings suggest complex interactions among age, body mass index, and parity as to how uterine cancer treatment affects pelvic floor quality of life, which should be considered in the choice of treatment strategy and patient counseling.

Highlights Choriocarcinomas can follow molar, ectopic, or normal pregnancies. The early diagnosis and treatment of choriocarcinomas is imperative. Atypical symptoms in pregnancy should raise suspicion for choriocarcinoma. Choriocarcinoma must always be in the differential in uncomplicated term pregnancies.
