Cytoreductive surgery (CS) and intraperitoneal hyperthermic chemotherapy (IPHC) can improve outcomes for selected patients with peritoneal carcinomatosis (PC) from colorectal cancer. The presence of parenchymal hepatic metastases (HM) is considered a relative contraindication for CS and IPHC. The purpose of the current study was to compare the overall survival of patients with HM to those without and to examine predictive factors.


This was a retrospective study of patients undergoing CS and IPHC between 1991 and 2007. Clinicopathologic information was obtained from a prospectively collected database and electronic medical records. Univariate and multivariate analyses were performed to evaluate variables predictive for overall survival.


There were 142 patients who underwent CS and IPHC for PC from colorectal cancer, with 14 (9.9%) patients noted to have concurrent HM. The median number and size of the liver lesions was 1 (range, 1-7 lesions) and 3.0 cm (range, 0.4 cm-12 cm), respectively. The median overall survival for patients with HM was 23.0 months. Two-year and 4-year survival rates were 43.3% and 14.4%, respectively. Patients without HM had 2-year and 4-year survival rates of 36.8% and 17.4%, respectively. Overall survival was not significantly different for patients with and without HM (log-rank P=.39).


Patients with HM undergoing CS and IPHC for colorectal cancer were found to have no significant difference in overall survival compared with those without HM. Most patients had a single small lesion treated with a minor hepatic resection. Further study is indicated to define which patients with HM benefit most from this multimodality approach.
