BACKGROUND Recurrence of small hepatocellular carcinoma (HCC) is common. Recent studies have suggested that the status of the underlying liver parenchyma is a significant risk factor for recurrence of HCC. METHODS The postoperative values of transaminase were examined every 6 months after surgery in 57 patients with a surgically resected solitary small HCC measuring up to 3 cm in greatest dimension. Based on the patterns of the transaminase values, the patients were divided into two groups. Group I (n = 20) had a high transaminase level; the values of postoperative transaminase were always more than 100 IU/L. Group II (n = 37) had a low transaminase level; the values of postoperative transaminase were sometimes lower than 100 IU/L. RESULTS The cumulative carcinoma‐free survival rates in Groups I and II were 91% and 80%, respectively, at 1 year, 64.5% and 5.5%, respectively, at 3 years, and 48.2% and 0%, respectively, at 5 years after surgery. The disease free survival rates in Group I were significantly lower than those in Group II ( P = 0.0007), although no significant differences in histologic risk factors for recurrence or in clinical backgrounds were observed. With regard to the recurrence pattern, solitary recurrence was more frequently observed in Group I ( P = 0.02), compared with the patients in Group II. A histologic comparison between the primary and recurrent tumor in patients who underwent re‐resection for solitary recurrence demonstrated the possible multicentric occurrence of HCC in 2 of 8 patients (25%) in Group I. CONCLUSIONS This study suggests that the hepatitis status of the remnant liver plays an important role in the recurrence rates and patterns of small HCC after hepatectomy. Cancer 1996;77:1050‐5.
