Study Population
Patients with hepatocellular carcinoma (HCC) who underwent radiofrequency ablation (RFA) from 1/2006 till 12/2010in Tropical medicine department and hepatocellular carcinoma clinic, Ain Shams university

Inclusion Criteria:

  1. Proved diagnosis of HCC according to AASLD practice guidelines (Bruix and Sherman, 2005).
  2. Patients underwent RFA for HCC with BCLC (The Barcelona-Clinic- Liver-Cancer staging system) stage A (Bruix and Sherman, 2005) with no eligibility or ability to do transplantation or resection.
  3. Patients should be followed-up for more than 12 months to exclude early recurrence i.e. recurrence within 1 year.
  4. Patients with INR < 1.5 or prothrombin concentration > 50%.
  5. Platelet count > 50000 cell/mm3.

Exclusion Criteria:

  1. Presence of extra-hepatic metastasis or gross vascular invasion.
  2. Child class C patients.
  3. Follow up period of less than 12 months.
