Treatment of nonresectable hepatocellular carcinoma: review of the literature and meta-analysis.
Many doubts surround the numerous forms of nonsurgical treatment of nonresectable hepatocellular carcinoma (HCC). Our study aimed to reach reliable conclusions on the actual efficacy of these treatments. We examined 85 studies involving a total of 6746 patients: 6113 were treated; the remaining 633 were not. We applied the Mantel-Haenszel-Peto method to the extrapolated data, based on the reported 1- and 3-year survival rates. The results confirm that percutaneous ethanol injection achieved survival exceeding 5 years in many cases of HCC characterized by small nodules (diameter < 3 cm). The most efficacious nonsurgical treatment options were transcatheter arterial embolization and transcatheter arterial chemoembolization. Systemic chemotherapy and hepatic intra-arterial chemotherapy were not very effective.
