Background: Patients with small hepaiocellular carcinoma (HCC) are usually treated with hepatic resection or percutaneous ethanol injection (PEI). Goals: To compare the effects of hepatic resection versus PEI on survival in a matched case-control study. Study: Patients with single-nodule HCC (: 5 cm) who were treated with hepatic resection (cases) or PEI (controls) were eligible. Matching criteria were date of diagnosis, Child-Pugh stage, and age at diagnosis. Kaplan-Meier survival curve of the control group was drawn weighing each stratum by the inverse of its size. Treatments were compared by a stratified Cox's model, adjusted by CLIP score. Results: Of 912 patients, 197 were eligible and 82 (17 cases and 65 controls) were matched, creating 17 strata. Nine (53%) cases and 41 (63%) controls died. Cox model showed no survival difference between the two groups; hazard ratio of PEI versus hepatic resection was 1.04 (95% CI = 0.43-2.52). One- and 3-year survival rates in the hepatic resection and PEI groups were 82% versus 91% and 63% versus 65%, respectively. Conclusions: Patients with small HCC treated with hepatic resection or PEI have similar survival rates. In view of the higher cost and morbidity of hepatic resection, a prospective randomized study is warranted.
