Risk factors for early death due to recurrence after liver resection for hepatocellular carcinoma: Results of a multicenter study

Abstract

Background and Objectives Recurrence after partial liver resection for hepatocellular carcinoma (HCC) is a major cause of death from this disease. To identify risk factors for early death from recurrence after liver resection for HCC. Methods All 547 patients in this study had greater than 1 year of follow‐up after complete resection of HCC (1980–1999) at one of the four hepatobiliary centers in Japan, France, and the United States. Patients who died of recurrence ≤1 year post‐resection and all of those alive at least 1 year were compared. Survival and clinicopathological factors associated with death from recurrence within 1 year of resection were analyzed. Results Overall postoperative mortality rate was 5%. In the first postoperative year, 123 (22%) patients died. Of these, 53 (43%) died of recurrence, 30 (24%) of postoperative complications, and 40 (33%) of liver failure/hemorrhage. On multivariate analysis, tumor size greater than 5 cm (P < 0.02; odds ratio, 3.0), multiple tumors (P < 0.01; odds ratio, 3.3), and greater than 5 mitoses per 10 high‐power fields (P < 0.03; odds ratio, 3) were associated with increased risk of early death due to recurrence. Conclusions These findings enable identification of patients with HCC who are at high risk for early death due to recurrence following potentially curative resection who might be candidates for adjuvant therapy trials.
