Preoperative Immunonutritional Scores as Predictors of Mortality and Recurrence in Patients with Peritoneal Carcinomatosis Secondary to Serous Ovarian Cancer Undergoing Cytoreductive Surgery and HIPEC

Hyperthermic intraperitoneal chemotherapy (HIPEC) combined with cytoreductive surgery (CRS) has become an increasingly preferred treatment for women with ovarian cancer presenting with peritoneal involvement. However, due to the high morbidity of HIPEC, accurate preoperative patient selection is essential. This study aimed to evaluate the prognostic value of immunonutritional indices—CALLY (C-reactive protein, albumin, lymphocyte) and Prognostic Nutritional Index (PNI)—in predicting early mortality and recurrence in patients undergoing CRS and HIPEC. A retrospective analysis was conducted on 49 female patients. Low CALLY (
