Curative treatments and survival benefit in elderly patients with hepatocellular carcinoma: A SEER population-based analysis.
355 Background: Transplant, resection, and ablation are potentially curative treatments for hepatocellular carcinoma (HCC) with limited outcome data in young-old (65-74) and older (≥75) patients. Methods: We evaluated curative treatment and relative survival (RS) outcomes in patients with HCC in 3 age groups (<65 years, 65-74 years, and ≥75 years). Patients with HCC diagnostic codes (histology 8,170-8,175, morphology C22) were identified in the SEER 18 database from 2000 to 2011. Treatments included curative (transplant, resection, radiofrequency ablation (RFA), and other ablations) and palliative therapies. Primary outcome was 5 year RS. Statistical analysis was performed using Kaplan-Meier and Chi-Square tests. Results: We identified 29,654 cases. The mean age was 62 years with almost 40% of HCC cases in patients over 65 years old. Potentially curable, localized stage rates were similar in all age groups, 46%, 48% and 46%, respectively. As a result of less resection and rare transplant use, fewer cases underwent curative treatments in the group 75 years and older in comparison to all other age groups (15% vs. 27%, p = 0.001). Five-year RS in all 3 age groups (<65 years, 65-74 years, and ≥75 years) was better after resection relative to RFA (47% vs. 35% p<0.0001, 44% vs. 37%, p=0.0093, and 43% vs. 28% p=0.0002). The highest survival was seen after liver transplant. Interestingly, among transplanted patients with HCC, 13% were 65-75 years old. Five-year RS was similar in transplanted patients 65-75 vs. those under 65 (76% vs 74% p=0.65). Conclusions: The use of curative treatments for HCC significantly decreases with age, yet there are clear survival benefits in elderly patients receiving such. Even when considering transplant, the data shows that outcome is as good in elderly patients as in younger patients. The benefit of hepatic resection appears to be superior compared to RFA in all age groups, in our analysis. [Table: see text]
