Twenty cases of borderline ovarian tumors were seen in the Department of Gynecology and Obstetrics at the St. Antoine Hospital over 5 years. The epidemiological study of these 20 tumors, relative to 47 invasive ovarian carcinomas seen over the same period, shows that hypofertility is more prevalent and that patients are younger. Diagnosis rests mainly on the histological examination of the operative specimen. The overall prognosis is good but recurrences, which may be delayed, are possible. These patients, who are often young, may be managed conservatively, at the cost of prolonged follow-up, including cytologic and coelioscopic examinations.

Surrogate End Points for Overall Survival in Neoadjuvant Randomized Clinical Trials for Early Breast Cancer.
J Clin Oncol
January 2025
German Breast Group, Neu-Isenburg, Germany.
Purpose: To assess trial-level surrogacy value for overall survival (OS) of the pathologic complete response (pCR) and invasive disease-free survival (iDFS) in randomized clinical trials (RCTs) for early breast cancer (BC).
Methods: Individual patient data of neoadjuvant RCTs with available data on pCR, iDFS, and OS were included in the analysis. We used the coefficient of determination from weighted linear regression models to quantify the association between treatment effects on OS and on the surrogate end points.
Ovarian cancer prevention through opportunistic salpingectomy during abdominal surgeries: A cost-effectiveness modeling study.
PLoS Med

Department of Gynecology and Reproductive Medicine, University Hospital Jena, Friedrich Schiller University Jena, Jena, Germany.
Background: There is indication that the fallopian tubes might be involved in ovarian cancer pathogenesis and their removal reduces cancer risk. Hence, bilateral salpingectomy during hysterectomy or sterilization, so called opportunistic salpingectomy (OS), is gaining wide acceptance as a preventive strategy. Recently, it was discussed whether implementation of OS at other gynecologic surgery, e.

Department of Radiology, First Affiliated Hospital of Guangxi Medical University, No.6 Shuangyong Road, Nanning, Guangxi, 530021, China.
In this study, spatial and single-cell transcriptome techniques were used to investigate the role of beta-galactoside alpha-2,6-sialyltransferase 1 (ST6GAL1) in promoting peritoneal metastasis in ovarian cancer epithelial cells. We collected single-cell transcriptomic (GSE130000) and spatial transcriptomic datasets (GSE211956) from the Gene Expression Omnibus and RNA-sequencing data from The Cancer Genome Atlas. The Robust Cell Type Decomposition (RCTD) approach was implemented to integrate spatial and single-cell transcriptomic data.

Background: Ovarian cancer (OC) represents a common neoplasm within the female reproductive tract. The prognosis for patients diagnosed at advanced stages is unfavorable, primarily attributable to the absence of reliable screening markers for early detection. An elevated neutrophil-to-lymphocyte ratio (NLR) serves as an indicator of host inflammatory response and has been linked to poorer overall survival (OS) across various cancer types; however, its examination in OC remains limited.

Ovarian sex cord-stromal tumors (SCST) are a rare subset of ovarian neoplasms originating from supportive tissues surrounding oocytes. Despite their rarity, prompt diagnosis and management are crucial due to their potential for diverse clinical presentations and the need to optimize patient outcomes. A 25-year-old female patient was initially diagnosed with pyelonephritis but later discovered to have a large right adnexal mass suspected to be a tubo-ovarian abscess.
