Background It has been suggested that adverse postoperative outcomes may have a negative impact on longterm survival in patients with colorectal liver metastases. Objectives This study was conducted to evaluate the prognostic impact of postoperative complications in patients submitted to a potentially curative resection of colorectal liver metastases. Methods A retrospective analysis of outcomes in 199 patients submitted to hepatic resection with curative intent for metastatic colorectal cancer during 1999-2008 was conducted. Results The overall complication rate was 38% (n = 75). Of all complications, 79% were minor (Grades I or II). There were five deaths (3%). The median length of follow-up was 39 months. Rates of 5-year overall and disease-free survival were 44% and 27%, respectively. Univariate analysis demonstrated that an elevated preoperative level of carcinoembryonic antigen (CEA), intraoperative blood loss of >300 ml, multiple metastases, large (≥35 mm) metastases and resection margins of <1 mm were associated with poor overall and disease-free survival. In addition, male sex and synchronous metastases were associated with poor disease-free survival. Postoperative complications did not have an impact on either survival measure. The multivariate model did not include complications as a predictive factor. Conclusions Postoperative complications were not found to influence overall or disease-free survival in the present series. The number and size of liver metastases were confirmed as significant prognostic factors.
