4138 Background: Multiple case series have described the use of current therapies for hepatocellular carcinoma (HCC), but recent estimates of treatment utilization in the general population and the impact of various treatments on survival are not known. Methods: We first identified 2898 adults diagnosed with HCC with known tumor size and stage in the Surveillance, Epidemiology, and End-Results Program (SEER), from 1998–2002. Treatment was categorized as transplant, resection, ablation, or none of these. We created a second data set of 1856 HCC patients who were potentially operable, as defined by SEER. We used these patients to construct Kaplan-Meier survival curves and adjusted Cox proportional hazards models. Results: The median age of the larger cohort at HCC diagnosis was 62 (range:18–96). Approximately 42% were white, 32% Asian, 16% Hispanic, and 10% African American. Overall, 10% received a transplant, 18% resection, 8% ablation, and 65% none of these. Only 5% of African Americans with HCC received a transplant, versus 12% of whites, 10% of Hispanics, and 8% of Asians. Asians were most likely to receive resection (24%) and ablation (9%), and least likely to have non-surgical treatment (60%). Using the restricted cohort, improved survival in the multivariate analysis was seen with later year of diagnosis, younger age, female sex, Asian race, smaller tumor size, lower tumor grade, and localized disease. Treatment was highly correlated with survival. This was greatest in the transplanted group (1, 3, and 5-year survivals 93%, 79%, and 71%), followed by resection (70%, 45%, and 29%), and ablation (71%, 33%, and 18%). The non-surgical group had poor survival (33%, 9%, and 0%). Conclusions: Transplantation yields excellent survival on a population scale, similar to reported series, and resection gives relatively good outcomes as well. Asians are more likely to be resected and ablated than other groups. They also had better survival than other groups, perhaps due to underlying etiology of HCC (hepatitis B) and better preserved liver function. No significant financial relationships to disclose.
