Impact of diabetes mellitus on outcome of HCC

Background: Diabetes mellitus (DM) is recently identified risk factor for development and progression of chronic liver disease as well as hepatocellular carcinoma (HCC). We planned a prospective analysis to identify impact of DM in Indian patients with HCC. Methods: During last 10 years, 160 consecutive patients of HCC were evaluated. Demographic profile like age of presentation, clinical features, etiology of HCC, tumor size at presentation, management and ultimate outcome was compared diabetic with non-diabetic HCC patients. Results: During last 10 years, 160 consecutive patients of HCC were evaluated (Mean age = 59.6 ± 12.9 years, sex ratio (M: F) = 5.4: 1). Etiology for HCC were hepatitis B in 45 (28.2%), hepatitis C in 18 (11.3%), alcohol in 27 (16.8%), alcohol with hepatitis B in 12 (7.5%), alcohol with hepatitis C in 1 (0.6%), non-alcoholic steatohepatitis in 4 (2.5%) and cryptogenic in 53 (33.2%) patients. Patients of HCC with DM (group-A, n =46, age = 62.6 ± 9.5 years, sex (M: F) = 6.6:1) were compared with patient of HCC without DM (group-B, n =114, age = 66.7 ± 13.7 years, sex (M: F) = 5.4:1). Duration of diabetes in group-A was 7.6 ± 3.2 years. Patients in group-A had more advanced HCC (size of lesion > 5 cm and >3 lesions of 3 cm or more diameter, portal vein thrombosis or intra-hepatic bile duct involvement) than group-B [34 (73.9%) vs 72 (54.3%)]. Mortality with in one year was significantly more in group-A compared to group-B [36 (78.2%) vs 56 (49.1%)]. Conclusion: DM is associated with more advanced lesion and poor outcome in patient with HCC.
