Cytoreductive Surgery and Intraperitoneal Chemotherapy for Peritoneal Metastasis of Colorectal Cancer: Long-Term Follow-Up Results at a Single Institution in Korea

This study aimed to examine the 7-year follow-up results of cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) for peritoneal metastasis (PM) of colorectal cancer. We performed 54 cases of CRS and IPC in 53 patients with PM of colorectal cancer from December 2011 to December 2013. We prospectively collected data and analyzed peritoneal carcinomatosis grade, completeness of cytoreduction, and long-term follow-up (median, 10 [range, 2–92] months) results. The mean peritoneal cancer index was 15 (1 35), and complete cytoreduction was possible in 35 (64.8
