Treatment of hepatocellular carcinoma smaller than 5 cm by transcatheter arterial chemoembolization

To assess the effectiveness of transcatheter arterial chemoembolization (TACE) in the treatment of small hepatocellular carcinoma (HCC) and to analyze the prognostic factors, a total of 77 patients with histologically proven HCC, < or = 5 cm in diameter, were enrolled for the study and followed for more than 2 years, The overall cumulative 1-, 2-, and 3-year survival rates were 79.2%, 50.6% and 36.7%, respectively. The median survival time of Child-Pugh's A patients was 990 +/- 146 days, which was significantly better than the median survival time of Child-Pugh's B patients (450 +/- 82 days) Furthermore, positive HBeAg and alpha-Fetoprotein (AFP) were factors close to statistically significant. In contrast, sex, age, HBsAg, Anti-HCV, tumor type, tumor size and tumor number were not related to the prognosis in small HCC who received TACE.
