Recent Therapies and Biomarkers in Mucinous Ovarian Carcinoma

Mucinous ovarian carcinoma (MOC) represents a rare and biologically distinct subtype of ovarian cancer, characterized by poor response to standard platinum-based chemotherapy and a unique molecular profile, including frequent KRAS mutations and HER2 amplifications. Recent advancements in targeted therapy, such as HER2 inhibitors and KRASG12C inhibitors, offer promising avenues for personalized treatment. Immunotherapy, particularly checkpoint inhibitors, shows potential in tumors with high PD-L1 expression or tumor mutational burden. Novel strategies, including antibody–drug conjugates, synthetic lethality approaches, and Wnt/β-catenin pathway inhibitors, are reshaping the therapeutic landscape. Despite these developments, challenges such as intratumoral heterogeneity and therapy resistance persist, underscoring the need for innovative clinical trial designs and combination regimens. This review synthesizes the latest advancements in MOC therapies, highlighting opportunities for improved outcomes in this challenging malignancy.
