Abstract
Surgical resection continues to offer the only hope for cure of colorectal cancer metastatic to the liver. Tumor involvement of the vena cava is often viewed as a contraindication to surgical resection. Whereas proven technically feasible, the survival advantages of en bloc liver and vena cava resection remain unclear. We reviewed all patients at a tertiary care center who had resection of colorectal liver metastases, including those with vena cava resections. Eleven patients had en bloc liver and vena cava resection between 1988 and 2002; during the same time period, 97 patients underwent isolated liver resection. There were no perioperative deaths in the 11 patients. All resections had negative histological margins. Mean follow-up was 33 months from the date of surgery. Median disease-free survival of the group having caval resections was 9 months, whereas median survival was 34 months. When compared to the cohort of isolated hepatic resections, the group undergoing caval resections experienced a significantly reduced diseasefree survival of 18.6 vs. 9.1 months, respectively (P = 0.03); however, there was no difference in overall survival between the two groups at 55.2 vs. 34.3 months, respectively (P = 0.20). Colorectal liver metastases involving the vena cava should be considered for surgical resection.
