Preoperative CA125 value predicts Glisson capsule involvement in patients with peritoneal carcinomatosis undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

The difficulty of detecting lesions smaller than 1 cm in the preoperative period is still a continuing problem in peritoneal carcinomatosis. The prospective data of 106 peritoneal carcinomatosis patients were included this study. Preoperative AFP, carcinoembryonic antigen, CA19.9, CA125, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, mean platelet value, platelet distribution width, red cell distribution width and radiological findings compared according to Glisson capsule tumor involvement. Preoperative radiological imaging methods have low accuracy in demonstrating Glisson capsule involvement. Inflammatory and serum tumor markers, except CA125, have been shown to be ineffective at detecting preoperative Glisson capsule involvement. CA125 levels higher than 52.4 were found to be significant in indicating Glisson's capsule involvement. CA125 is more sensitive than radiological and nuclear imaging methods in detecting tumors smaller than 1 cm.
