Concordance of folate receptor expression in ovarian cancer over time: A single-institution retrospective study
Background Folate receptor alpha (FRα) is frequently expressed in ovarian high-grade serous carcinomas and is a clinically actionable biomarker targeted by FDA-approved mirvetuximab soravtansine (MIRV) for platinum-resistant disease with high expression (≥75% of tumor cells with ≥2+ staining). However, longitudinal var...
