BACKGROUND. The purpose of this study was to examine the clinical presentation, prognostic factors, and survival rates of patients with hepatocellular carcinoma (HCC) and to examine differences between Asian and non-Asian patients with HCC. METHODS. A review of the clinical characteristics and laboratory evaluations for 76 patients in two different broad ethnic groups (Asians [Group 1] and non-Asians [Group 2]) who underwent treatment for HCC from 1977-1995 was performed. Chi-square and Cox regression analyses were performed to assess factor interaction and association with survival. RESULTS. A total of 24 patients in Group 1 and 52 patients in Group 2 were reviewed. Of the clinical variables examined, a higher rate of a history of hepatitis B positivity was observed in Group 1 compared with Group 2 (32% vs. 6%; P = 0.001). Among the 76 patients with HCC, a 1-year survival estimate of 41.4% was found. There was a borderline significant difference in survival between Group 1 and Group 2 with a 1-year survival estimate of 29.5% versus 46.9%, respectively (P = 0.08). Better overall survival was found in patients who had tumors that were resectable (P = 0.0001), had an α- fetoprotein level < 10 ng/mL (P = 0.02), or were a younger age at the time of diagnosis (P = 0.01). There was a trend for Asian race (P = 0.08) to be associated with poorer survival. When these risk factors were entered into a multivariate analysis, tumor resectability and non-Asian race were most predictive of improved survival (model P value = 0.007). When controlling for the multiple variables most often reported to be associated with HCC, Asians had a significantly lower survival than non-Asians (P < 0.01). CONCLUSIONS. In this study it appears that the outcome for Asian patients with hepatoma is worse than for non-Asian patients, even when controlling for factors commonly associated with HCC. Biologic or social factors that are not appreciated currently may be involved in Asian patients with HCC, contributing to a poorer clinical outcome.
