Predictors of long-term survival in hepatocellular carcinomas: A longitudinal follow-up of 108 patients with small tumors

Aim: Locoregional treatment [including percutaneous ethanol injection (PEI) therapy and transcatheter arterial chemoembolization (TACE)] provides an alternative treatment for early-diagnosed hepatocellular carcinoma (HCC). However, the long-term survival of patients after locoregional treatments remains unclear. Patients and Methods: A total of 108 patients with small HCC not indicated for surgical hepatic resection were recruited between 1991 and 1999. All patients received first treatment with PEI therapy alone or combined with TACE. We followed-up these patients until the end of 2007. Clinical attributes and biological markers in association with long-term survival were collected. Significant predictors were identified by using proportional hazards regression model. Results: The overall 1-, 3-, 5-, and 10-year cumulative survival of patients with HCC (
