Predictive impact of clinical factors on chemosensitivity in advanced high-grade serous ovarian carcinoma according to chemotherapy response score.

The use of neoadjuvant chemotherapy (NAC) as a first-line therapy for advanced high-grade serous ovarian carcinoma (HGSOC) has increased. However, several studies have reported NAC-induced platinum resistance. This study aimed to evaluate the predictive impact of clinical factors on chemotherapy response score (CRS) and to select patients who would respond well to NAC.

Background: Predictive, preventive, and personalized medicine (PPPM/3PM) is a strategy aimed at improving the prognosis of cancer, and programmed cell death (PCD) is increasingly recognized as a potential target in cancer therapy and prognosis. However, a PCD-based predictive model for serous ovarian carcinoma (SOC) is lacking. In the present study, we aimed to establish a cell death index (CDI)-based model using PCD-related genes.

Homologous recombination repair deficiency (HRD) is involved in the development of high-grade serous ovarian carcinoma (HGSOC) and its elevated sensitivity to platinum-based chemotherapy. To investigate the heterogeneity of the HRD-positive HGSOC we evaluated the HRD status, including BRCA mutations, genomic scar score, and methylation status of genes in 352 HGSOC specimens. We then divided the HRD-positive cohort into three molecular subgroups, the BRCA mutation cohort (BRCA+), BRCA1 methylation cohort (Meth+), and the rest of the HRD+ cohort (HRD+BRCA-Meth-), and evaluated their first-line chemotherapy response, benefit from olaparib, and progression-free survival (PFS).

High-grade serous ovarian carcinoma (HGSOC) remains the most common and deadly form of ovarian cancer. However, available cell lines usually fail to appropriately represent its complex molecular and histological features. To overcome this drawback, we established OVAR79, a new cell line derived from the ascitic fluid of a patient with a diagnosis of HGSOC, which adds a unique set of properties to the study of ovarian cancer.

The most common histological subtypes of endometrial cancer consist of endometrioid and uterine serous carcinoma, with the latter being more aggressive and accompanied by poor prognosis. Human epidermal growth factor receptor 2 (HER2) is a transmembrane tyrosine kinase receptor associated with cell proliferation, differentiation, and survival. HER2 positivity can be diagnosed in many solid tumors.
