The aim of this study was to examine the early surgical and long-term survival outcomes of cytoreductive surgery (CRS) alone and CRS plus perioperative intraperitoneal chemotherapy (IPC) in patients with peritoneal metastases (PM). CRS alone or CRS plus IPC was performed on 122 patients for various intraabdominal PMs. Patients were divided into two groups as PCI ≤19 and PCI >19 to compare early surgical outcomes. Among PM patients 70 (57.4%) were of non-ovarian and 52 (42.6%) were of ovarian origin. Of the patients 74 (60.7%) were in the peritoneal cancer index (PCI) ≤19 group and 48 (39.3%) were in the PCI >19 group. The complication ratio of PCI >19 group was higher than that of the PCI ≤19 group and median overall survival (OS) of PCI >19 group was lower than that of the PCI ≤19 group. Complete or nearly complete (CCR-0/CCR-1) resections rates were similar in both groups (95.9% in the PCI ≤19 group and 93.8% in the PCI >19 group). However, CCR-0 resection rate was found to be lower in the PCI >19 group compared to the PCI ≤19 group (60.8% vs. 39.6%) (p 19 score. It would be appropriate to consider CRS or CRS plus perioperative IPC for palliative purposes in selected patients with PCI >19 score.
