Ovarian cancer stands as the most lethal gynecologic malignancy and remains the fifth most common gynecologic cancer. Poor prognosis and low five-year survival rate are attributed to nonspecific symptoms at early phases along with a lack of effective treatment at advanced stages. It is thus paramount, that ovarian carcinoma be viewed through several lenses in order to gain a thorough comprehension of its molecular pathogenesis, epidemiology, histological subtypes, hereditary factors, diagnostic approaches, and methods of treatment. Above all, it is crucial to dissect the role that the unique peritoneal tumor microenvironment plays in ovarian cancer progression and metastasis. This short communication seeks to underscore several important aspects of the PI3K/AKT/mTOR/NFκB pathway in the context of ovarian cancer and discuss recent advances in targeting this pathway.

Resistance to platinum-based drugs and PARP inhibitors (PARPi) is the leading cause of treatment failure in epithelial ovarian cancer (EOC). This study aimed to identify resistance mechanisms shared by both. Using bioinformatic analyses, EOC tissues, primary tumor cells and organoids, and chemoresistant cell lines, we identified lymphoid enhancer-binding factor 1 (LEF1) as a candidate, whose expression was increased in both platinum-resistant and PARPi-resistant tumors.

Granulosa cell tumors (GCTs) are rare ovarian neoplasms, accounting for 2-5% of all ovarian cancers. Two histological types have been described: juvenile (JGCT) and adult (AGCT), the latter accounting for around 95% of the GCTs. AGCTs are mostly diagnosed at an early stage and commonly have a good prognosis.

Background: Tumor heterogeneity and antigen escape are mechanisms of resistance to chimeric antigen receptor (CAR)-T cell therapy, especially in solid tumors. Targeting multiple antigens with a unique CAR construct could be a strategy for a better tumor control than monospecific CAR-T cells on heterogeneous models. To overcome tumor heterogeneity, we targeted mesothelin (meso) and Mucin 16 (MUC16), two antigens commonly expressed in solid tumors, using a tandem CAR design.

Purpose: Ovarian cancer ranks as a gynecological malignancy with poor prognosis, specifically if detected late. Primary treatment includes cytoreductive surgery and adjuvant chemotherapy with curative intent. Local anesthetics (LA) administered in the perioperative period may potentially impact patient outcome by several mechanisms.

Background: Homologous recombination deficiency (HRD)-related genetic mutations in ovarian high-grade serous carcinoma (HGSC) are known to be ethnic specific. Here, we assessed the diagnostic performance of HRD and its clinical implication in Korean HGSC patients using the SOPHiA DDM HRD Solution.
Methods: Sixty-three ovarian cancer (OC) patients were enrolled, including 53 with HGSC and 10 with other subtypes.
