Introduction: Many clinical trials have been published trying to address the outcome of patients with hepatocellular carcinoma. Hepatitis B is one of the leading causes of hepatocellular carcinoma and liver failure in many parts of the world. We performed this retrospective study in order to evaluate if patients with hepatitis B had a worst outcome after non surgical treatment. Methods: We reviewed 32 consecutive medical records of patients with hepatocellular carcinoma and no criteria for surgical treatment (1999- 2005), treated with chemoembolization, transarterial chemotherapy , radiofrequency or percutaneous alcohol ablation . The patients were classified according to the Child Pugh Score, cause of liver disease associated with HCC, tumour characteristics (size and number), and treatment received. The main endpoint was fatality. Survival curve was calculated with the Kaplan Meier's method . Results: There were 32 patients with non surgical treatment, male to female ratio 23:9. 23 patients were Child A (71.87%), 8 Child B (25%) and 1 Child C (3,12%) . 24 patients had tumor size > 5 cm. In the chemoembolization group survival at 180 days was 75% and in one year 58%, 66% and 25% in patients treated with intrarterial chemotherapy. One year survival with radiofrequency was 66% and with percutaneous alcohol injection 50%. Patients with hepatitis B had the worst survival (P=0,002). Conclusions: Hepatitis B is a major determinant in worst survival outcome in patients with non surgical treatments.
