Clinicopathologic factors influencing long-term survival after resection for hepatocellular carcinoma.

BACKGROUND: The purpose of this study is to investigate the clinicopathologic factors that influence a survival longer than 5 years with no recurrence in patients after resection for hepatocellular carcinoma (HCC). METHODS: Between January 1992 and December 1994, 64 patients with complete viral markers study underwent curative hepatic resection for HCC. Four patients who died of surgical morbidity (hospital mortality, 6.3%) were excluded from this study. Among the 60 patients who survived, 10 patients (16.7%) survived over 5 years without recurrence. The clinicopathologic features and surgical procedures of the patients with long-term survival (> or = 5 years) without recurrence (n = 10) were compared with those of less than 5 years survival or with tumor recurrence (n = 50). The median follow-up was 64.8 months, ranging from 61.1 to 76.7 months. RESULTS: Six of the 10 patients were men with an age ranging from 35 to 75 years (mean, 57.6 +/- 9.7). Using univariate analysis, long-term survival without recurrence was significantly associated with a lower amount of perioperative blood transfusion (less than 7 units, p = 0.036) and an existence of tumor capsule (p = 0.031). But in multivariate analysis, only the presence of tumor capsule was statistically significant. CONCLUSIONS: Long-term survival without recurrence was related to a lower amount of perioperative blood transfusion, and an existence of tumor capsule in univariate analysis. But in multivariate analysis, only the existence of tumor capsule plays a significant role.
