Heterogeneity of folate receptor alpha expression and associations with molecular biomarker in ovarian high-grade serous carcinoma: A multicenter Chinese cohort study.
BACKGROUND Folate receptor alpha (FRα) is an established therapeutic target in ovarian cancer, but information on its expression distribution, staining heterogeneity, and molecular context in Chinese patients remains limited. We evaluated these features in ovarian high grade serous carcinoma (HGSC). METHODS This retr...
