The clinical and biochemical profiles and tumor characteristics in the HCC cases were also evaluated. Methods A total of 357 consecutive cases of HCC fulfilling the diagnostic criteria from the Barcelona-2000 EASL conference were included in the study. The blood samples were evaluated for serological evidence of HBV and HCV infection, viral load, and genotypes using serological tests, reverse transcription-polymerase chain reaction, and restriction fragment length polymorphism. Results The male/female ratio for the HCC cases was 5.87：1. Majority of the HCC patients （33.9%） were 50 to 59 years of age, with a mean age of 4±13.23 years. More than half the cases （60.8%） had underlying cirrhosis at presentation. Among the HCC patients, 68.9% were HBV related, 21.3% were HCV related, 18.8%, were alcoholic, and 18.2% were of cryptogenic origin. The presence of any marker positive for HBV increased the risk for developing HCC by almost 27 times [OR： 27.33; （12.87-60.0）]. An increased risk of 10.6 times was observed for HCC development for cases positive for ally HCV marker [OR： 10.55; （3.13-42.73）]. Heavy alcohol consumption along with HCV RNA positivity in cirrhotic patients was found to be a risk for developing HCC by 3 folds ]OR： 3.17; （0.37-70.71）]. Conclusions Patients of chronic HBV infection followed by chronic HCV infection were at higher risk of developing HCC in India. Chronic alcohol consumption was found to be a risk factor in cirrhotic cases only when it was associated with HCV RNA positivity. Most of the patients had a large tumor size （〉5 cm） with multiple liver nodules, indicating an advanced stage of the disease thus making curative therapies difficult.展开更多
