INTRODUCTION Hepatocellular Carcinoma (HCC) is the fifth leading cancer all over the world and is the third most common cause of cancer deaths. (1) Due to increasing prevalence of hepatitis [...]Objective: To determine the clinical, biochemical and radiological prognostic indicators and to compare the performance of six staging systems in patients of hepatocellular carcinoma (HCC). Study Design: Descriptive study. Place and Duration of Study: Department of Gastroenterology, Doctors Hospital, Lahore, from October 2007 to December 2013. Methodology: Patients with HCC were included. Baseline clinical, hematological and radiological variables were noted. Patients were followed for 5 years or till death. Survival predictors were identified using Cox proportional hazard analysis and 6 prognostic staging systems were evaluated by determining homogeneity, discriminatory ability and monotonicity. Results: Of the 228 patients included, male to female ratio was 2.6/1 (165/63) and mean age was 56.5 [+ or -] 10.4 years. Majority of patients 189 (82.9%) were anti-HCV positive. Solitary HCC lesion was seen in 121 (53.1%) patients, 16 (7%) had 2 lesions while 73 (32%) had 3 or more lesions. Only 36 (15.8%) patients had palliative therapy for HCC. Survival rate was 45.2%, 25%, 12.3%, 7%, 2.2% and 1% for 6 months, 1, 2, 3, 4 and 5 years respectively. Male gender, portal vein thrombosis, serum albumin
