Abstract | BACKGROUND. In patients with hepatocellular carcinoma (HCC), recurrences in the distant liver often are observed after curative treatment. Microwave coagulation therapy (MCT) and radio-frequency ablation [RFA] have been developed as less invasive alternatives than surgical resection for small HCCs. In the current study, risk factors for distant recurrence of HCC were analyzed in patients in whom complete coagulation was achieved. METHODS. Ninety-two patients with HCCs < 3 cm in greatest dimension were treated by MCT or RFA percutaneously or laparoscopically. Eighty-four patients in whom complete coagulation was achieved without recurrence in the same subsegment as the primary nodule were included in this study. Distant recurrences were observed in 22 patients. Fifteen possible risk factors for a distant recurrence were analyzed. RESULTS. When comparing the patients with a recurrence of HCC nodules in the remnant liver to those without recurrence, the authors observed a statistically significant difference only in serum α-fetoprotein. The distant recurrence-free survival was analyzed by the Kaplan-Meier method. A statistically significant difference was observed in hepatitis C virus (HCV) infection as an etiopathic agent of underlying liver diseases (P < 0.005) and in the number of the primary HCC nodules (P < 0.05, log-rank test). A multivariate step-wise Cox hazard model revealed that HCV infection and the number of primary HCC nodules were statistically independent risk factors. CONCLUSIONS. Patients who had more than two HCC nodules accompanied by HCV infection had a high incidence of recurrence of HCC in the remnant liver. Even when coagulation by microwave or ablation by radio-frequency was complete. © 2001 American Cancer Society. |
