Infective complications after cancer surgery had a significant impact on disease-free and overall survival. Postoperative inflammatory markers have been proven useful in predicting infective complications. However, it remains unknown whether these markers can predict postoperative infection in patients receiving cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) which causes the systemic inflammatory response syndrome. Between September 2014 and April 2017, all patients who underwent cytoreductive surgery and HIPEC for peritoneal carcinomatosis were assessed for postoperative complications. Patients were divided into two groups according to the presence of infective complications. Presence of abscess, positive blood, surgical site, urine or sputum cultures, or clinical signs and symptoms with comparable radiologic findings were defined as infective complications. Retrospectively, C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, white blood cell count, platelet count, mean platelet volume, platelet-to-lymphocyte ratio, albumin were collected from preoperative day and postoperative days (POD) 0-14.
