Serous carcinomas most commonly arise within the uterine corpus or ovary/fallopian tube, but there are 2 prior case reports of primary vaginal serous carcinoma. We report 2 examples of high-grade serous carcinoma arising within the urethra or a urethral diverticulum (1 case each). Both neoplasms exhibited the classic morphologic features of high-grade serous carcinoma, and a combination of clinical, radiologic, and pathologic examination excluded other possible sites of primary neoplasm.

Background: Ovarian cancer (OC), particularly high-grade serous ovarian carcinoma (HGSOC), is the leading cause of mortality from gynecological malignancies worldwide. Despite the initial effectiveness of treatment, acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) represents a major challenge for the clinical management of HGSOC, highlighting the necessity for the development of novel therapeutic strategies. This study investigated the role of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a pivotal regulator of glycolysis, in PARPi resistance and explored its potential as a therapeutic target to overcome PARPi resistance.

To investigate the clinicopathological characteristics of solid, endometrial-like and transitional (SET) cell growth subtype in high-grade serous ovarian carcinoma (HGSC). Clinical data of 25 cases of HGSC-SET were collected from January 2020 to March 2024 at the Affiliated Suzhou Hospital of Nanjing Medical University, and their histological features were analyzed. Immunohistochemical stains were used to analyze the expression of ER, PR, PAX8, WT-1, p16, p53 and Ki-67.

Background: Chemoresistance is a major obstacle in high-grade serous carcinoma (HGSC) treatment. Although many patients initially respond to chemotherapy, the majority of them relapse due to Carboplatin and Paclitaxel resistance. Drug repurposing has surfaced as a potentially effective strategy that works synergically with standard chemotherapy to bypass chemoresistance.

Cancer immunotherapy through the use of PD-1/PD-L1 inhibitors have shown significant promise in endometrial carcinoma (EC), particularly in tumors with microsatellite instability (MSI) or mismatch repair deficiency (dMMR), present in approximately 30% of cases. This review evaluated PD-L1 and PD-1 expression as potential biomarkers for immunotherapy response in EC, focusing on their relationship with MSI status. A systematic review, adhering to PRISMA guidelines, analyzed studies from MEDLINE and Embase until February 2023 on PD-1/PD-L1 expression in EC stratified by MSI status, including diverse study designs but excluding conference abstracts, with independent screening, data extraction, and additional reference checks to ensure comprehensive coverage.
