Resection of hepatocellular carcinoma in cirrhotic patients: longterm results of a prospective study

Abstract

Background: Surgical resection of hepatocellular carcinoma in cirrhotic patients remains controversial because of a high reported recurrence rate. To assess the longterm results of resection, 37 patients included in a prospective study were followed for more than 5 years, with special interest in early detection of recurrence.

Study design: Resection was performed from 1986 to 1991 with the goal of sparing the functional liver parenchyma. The mean tumor diameter was 5.3 +/- 2.6 cm (range 2 to 11 cm). Nineteen patients had tumors smaller than 5 cm. No additional perioperative therapy was performed.

Results: Evidence of intrahepatic recurrence was demonstrated in 26 of the 33 patients surviving the operation. Eight recurrences (31%) were diagnosed from the third to the fifth postoperative years. The recurrence-free survival rates at 1, 2, 3, 4, and 5 years were 68%, 40%, 26%, 13%, and 9%, respectively. Only 2 patients (7%) were alive and free of recurrence at 5 years. Some long survivals were observed after treatment of recurrence. The overall survival rates at 3 and 5 years were 35% and 24%, respectively. Tumor cell differentiation was the only significant prognostic factor for both recurrence and survival. Multifocal tumors were associated with a higher recurrence rate. Patients with good liver function had longer survivals that reached 38% in those with small solitary tumors. Study of the other dinicopathologic factors failed to demonstrate any prognostic value.

Conclusions: Only a few patients are alive and free of recurrence 5 years after resection. Some long survival can be observed after treatment. Assessment of prognostic factors remains difficult, but the best results of resection are obtained in patients with small solitary hepatocellular carcinoma function.
