Research background

Sorafenib has been approved for use in unresectable hepatocellular carcinoma (uHCC) patients for more than a decade. As other therapies have been approved in recent years for uHCC treatment in later lines, it is essential to assess clinical effectiveness of older therapies in actual clinical practice to inform healthcare practitioners’ decisions for better patient care.

Research motivation

Limited recent data on real-world clinical effectiveness of sorafenib in diverse clinical practice settings in the United States.

Research objectives

To assess clinical effectiveness of sorafenib as first-line (1L) therapy in uHCC patients treated in both academic and community practice settings in the United States.

Research methods

In a retrospective observational study we assessed clinical outcomes including best response, progression-free survival (PFS), and overall survival (OS) among adult uHCC patients (≥ 18 years) in the United States initiating 1L sorafenib monotherapy at City of Hope (academic) and Advent Health (community practice) between January 2016 and December 2019.

Research results

Median time to treatment discontinuation was 2.3 mo. Overall, 103 patients (77%) had disease progression or died during sorafenib therapy. Median PFS was 2.9 mo and median OS was 8.5 mo.

Research conclusions

Median PFS and OS of sorafenib in 1L uHCC were < 3 mo and < 9 mo, respectively.

Research perspectives

Newer therapeutic options that have reported higher PFS and OS in real-world clinical practice should be considered to enhance patient outcomes.
