Abstract

To analyze the cost-effectiveness of radioembolization in the treatment of intrahepatic cholangiocarcinoma (ICC) using the Surveillance, Epidemiology, and End Results (SEER) Medicare cancer database. Cost as measured by total treatment-related reimbursement in patients diagnosed with ICC who received chemotherapy alone or chemotherapy and yttrium-90 radioembolization was assessed in the SEER Medicare cancer database (1999-2012). Survival analysis was performed, and incremental cost-effectiveness ratios were generated. The study included 585 patients. Average age at diagnosis was 71 years (standard deviation: 9.9), and 52% of patients were male. Twelve percent of patients received chemotherapy with radioembolization (n = 72), and 88% of patients (n = 513) received only chemotherapy. Median survival was 1043 days (95% confidence interval [CI]: 894-1244) for chemotherapy plus radioembolization and 811 days (95% CI: 705-925) for chemotherapy alone (P = .02). Patients who received combination therapy were slightly younger (71 vs 69 years, P = .03). No significant differences were observed between treatment groups in age at treatment, sex, race, or city size. Multivariable analysis showed a hazard ratio for progression for combinatio...Continue Reading
