abstract
BACKGROUND. Differences in survival and morbidity among treatment options (ablation, surgical resection, and transplant) for early-stage hepatocellular carcinoma (HCC) have been well studied. Additional understanding of the costs of such care would help to identify drivers of high costs and potential barriers to care delivery. OBJECTIVE. The purpose of this article was to quantify total and patient out-of-pocket costs for ablation, surgical resection, and transplant in the management of early-stage HCC and to identify factors predictive of these costs. METHODS. This retrospective U.S. population-based study used the SEER-Medicare linked dataset to identify a sample of 1067 Medicare beneficiaries (mean age, 73 years; 674 men, 393 women) diagnosed with early-stage HCC (size ≤ 5 cm) treated with ablation (n = 623), resection (n = 201), or transplant (n = 243) between January 2009 and December 2016. Total costs and patient out-of-pocket costs for the index procedure as well as for any care within 30 and 90 days after the procedure were identified and stratified by treatment modality. Additional comparisons were performed among propensity score-matched subgroups of patients treated by ablation or resection (each n = 172). Multivariable linear regression models were used to identify factors predictive of total costs and out-of-pocket costs for index procedures as well as for 30- and 90-day post-procedure periods. RESULTS. For ablation, resection, and transplant, median index-procedure total cost was US$6689, US$25,614, and US$66,034; index-procedure out-of-pocket cost was US$1235, US$1650, and US$1317; 30-day total cost was US$9456, US$29,754, and US$69,856; 30-day out-of-pocket cost was US$1646, US$2208, and US$3198; 90-day total cost was US$14,572, US$34,984, and US$88,103; and 90-day out-of-pocket cost was US$2138, US$2462, and US$3876, respectively (all p < .001). In propensity score-matched subgroups, ablation and resection had median index-procedure, 30-day, and 90-day total costs of US$6690 and US$25,716, US$9995 and US$30,365, and US$15,851 and US$34,455, respectively. In multivariable analysis adjusting for socioeconomic factors, comorbidities, and liver-disease prognostic indicators, surgical treatment (resection or transplant) was predictive of significantly greater costs compared with ablation at all time points. CONCLUSION. Total and out-of-pocket costs for index procedures as well as for 30-day and 90-day postprocedure periods were lowest for ablation, followed by resection and then transplant. CLINICAL IMPACT. This comprehensive cost analysis could help inform future cost-effectiveness analyses.
