Treatment Patterns and Economic Burden by Lines of Therapy Among Patients with Advanced Hepatocellular Carcinoma Treated with Systemic Cancer Therapy.

ABSTRACT:

Purpose

This study examined clinical and economic outcomes among patients with advanced hepatocellular carcinoma (HCC) treated with systemic agents by line of therapy.

Methods

Adults with ??2 medical claims for primary diagnosed HCC (from January 1, 2008, through September 30, 2015) and ??1 claim for systemic HCC-related therapy were identified in the IBM MarketScan® Research Databases. Continuous enrollment was required 6 months before and 1 month after diagnosis. Patients were categorized into first- (1L) and second-line (2L) treatment cohorts; those receiving sorafenib as 1L were evaluated. Treatment patterns, healthcare resource utilization, costs, and survival during 1L and 2L therapy were measured. Survival was assessed for patients linked to the Social Security Administration Master Death File.

Results

1459 patients, 758 with death data, met the 1L cohort criteria; 163 patients, 87 with death data, later received 2L therapy. 77.1% had 1L sorafenib, alone or in combination. Median 1L treatment duration was 3.0 months; median survival time from start of 1L to death or censor was 6.8 months. There was no predominant 2L agent. Median 2L treatment duration was 3.0 months; median survival time from start of 2L was 9.3 months. Median total healthcare costs per patient per month were $13,297 for 1L (all), $13,471 for 1L (sorafenib), and $11,786 for 2L.

Conclusions

Findings confirm high 1-year mortality for advanced HCC, suggesting a high cost burden. While no 2L therapy was available during this analysis, recently approved 2L agents have the potential to improve survival after sorafenib failure or intolerance.
