Transcatheter arterial chemoembolization for hepatocellular carcinoma.
The factors relating to the duration of survival were analyzed for 329 cases of hepatocellular carcinoma (HCC) treated by transcatheter arterial chemoembolization (TACE) between January 1, 1983, and December 31, 1990. The cumulative survival value obtained was slightly higher but not statistically significantly higher in these 329 cases as compared with the 129 cases reported in 1989. This improvement was probably attributable to careful selection of the patients on the basis of the clinical Child's status and to improvement of the superselective angiotechnique used in the present study. The overall cumulative 1-, 2-, and 3-year survival values in this series were 50%, 25%, and 15%, respectively. The median duration of survival was 12.7 months (Kaplan-Meier method). The 1-, 2-, and 3-year survival values determined for 190 patients in Child's group A, for 95 patients in Child's group B, and for 44 patients in Child's group C were 60%, 30%, and 20%; 35%, 20%, and 10%; and 35%, 20%, and 10%, respectively. Analyses were also carried out according to the tumor's type and size, the integrity of the tumor capsule, and the patency of the portal vein. Our results disclosed that a better outcome in terms of the median survival period and the survival value was favored by the following factors: a single lesion measuring less than 5 cm in diameter, an intact capsule, a patent portal vein, and a good clinical status. It is also essential that all patients who have undergone TACE be periodically evaluated by ultrasonography, CT, and angiography to determine whether repeated chemoembolization is necessary.
