Actual 10-year survival following hepatectomy for hepatocellular carcinoma.

OBJECTIVES

This study was conducted to compare 10-year survivors with patients who survived <10 years in a large Western series of patients submitted to hepatectomy for hepatocellular carcinoma (HCC).

METHODS

A retrospective review of a series of hepatic resections conducted in a referral centre for HCC between January 1987 and October 2002 was conducted.

RESULTS

A total of 176 patients were analysed. Twenty-eight patients survived ≥ 10 years (Group A) and were compared with the 148 patients who did not (Group B). Group A had smaller tumours (5.7 cm versus 8.2 cm; P = 0.001) and a lower incidence of microvascular invasion (18.5% versus 37.1%; P = 0.004). Recurrence did not differ significantly (Group A 18/28, 64.3% versus Group B 94/148, 63.5%). Median time to recurrence was longer in Group A (70 months versus 15 months; P < 0.0001), and more patients in Group A were able to undergo curative treatment for recurrence (88.8% versus 40.4%; P < 0.0001). Multivariate analysis showed that lack of vascular invasion (P = 0.020), absence of perioperative transfusion (P = 0.014), and recurrence at >2 years after primary resection (P = 0.045) were significantly associated with 10-year survival.

CONCLUSIONS

Ten-year survival after liver resection for HCC can be expected in approximately 15% of patients. Recurrence does not preclude longterm survival. Recurrence at >2 years after resection, absence of vascular invasion, and absence of perioperative transfusion are independently associated with 10-year survival.
