Preoperative HALP Profiles in Serous and Mucinous Epithelial Ovarian Tumors: Positioning Borderline Tumors on the Benign–Malignant Spectrum

Background/Objectives: Borderline ovarian tumors can overlap with benign and malignant adnexal masses in their preoperative features. The hemoglobin–albumin–lymphocyte–platelet (HALP) score reflects inflammatory and immunonutritional status. We compared HALP profiles across benign, borderline, and malignant epithelial ovarian tumors and secondarily explored their contribution beyond the risk of malignancy index (RMI).
