BACKGROUND/AIMS: Numerous prognostic factors for HCC have been reported. Few literatures have reported clinical significance of amount of intraoperative blood loss (ABL) for the outcome after surgery for HCC. The aim of this study is to analyze the significance of ABL for outcome after surgery for HCC. METHODOLOGY: A total of 301 patients who underwent liver resection for HCC between January 1998 and June 2007 were included. Clinical and surgical characteristics were collected and prognostic factors were identified using univariate and multivariate analysis. RESULTS: Impaired liver function (liver damage B), large tumor (>36mm), multiple tumors, existence of macroscopic vessel invasion, large ABL (=700mL) and replacement of red blood cells were identified as independent prognostic factors for overall survival (OS). For disease free survival (DFS), old age (>66), male gender, impaired liver function, large tumor, multiple tumors, existence of macroscopic vessel invasion and large ABL were extracted. Limited to the patients without blood transfusion, large ABL is associated with poor OS and DFS. CONCLUSIONS: Large ABL could result in poor OS and DFS after liver resection of HCC in patients without blood transfusion. Surgeons have to make the best effort to reduce ABL.
