Abstract

In Taiwan, colorectal cancer with peritoneal carcinomatosis is considered a terminal condition. We examined the clinical outcomes of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) treatment for colorectal cancer with peritoneal carcinomatosis in Taiwan. Weenrolled patients with colorectal cancer and peritonealmetastasis from Taipei Medical University, Wanfang Hospital between January 1999 and December 2014. Of the enrolled patients, 3 had mucinous-type tumors. In total, we enrolled 31 patients who underwent a total of 33 procedures. Of the 31 patients, 2 received the HIPEC procedure twice. Cytoreductive surgery was performed followed by HIPEC. The hazard ratios of death following cytoreductive surgery and HIPEC were calculated using the Cox proportional hazards model. The 2- and 5-year overall survival rates of these patients following cytoreductive surgery and HIPEC were 57% and 38%, respectively. The completeness of cytoreduction (CC) scores were CC-0, CC-1, CC-2, and CC-3 in 18 (54.5%), 3 (9%), 7 (21.2%), and 5 (15.2%) patients, respectively. The mean peritoneal cancer index (PCI) was 16.20, and the mean postoperative PCI (PPCI) was 4.6. The major risk factors for death in these patients were a total PCI score>20, total PPCI score > 0, and CC score ≥ 2 (P=0.022, 0.031, and 0.0001, respectively; log-rank test). Multivariate analysis revealed that the total PPCI score was the strongest predictor of death following cytoreductive surgery and HIPEC in these patients. In Taiwan, performing cytoreductive surgery and administering HIPEC for treating colorectal cancer with peritoneal metastasis are feasible and resulted in long-term survival. In addition, the total PPCI score was related to poor prognosis following cytoreductive surgery and HIPEC in patients with colorectal cancer and peritoneal metastasis.
