- Abstract
Simple Summary: Hepatocellular carcinoma is the most common type of liver cancer and is often seen in people with chronic liver diseases. For patients with hepatocellular carcinoma who cannot receive surgery, other treatments include atezolizumab plus bevacizumab, sorafenib, or lenvatinib. We compared the length of life among 1874 United States veterans who received these therapies, both in the overall population of patients and in groups by race/ethnicity. The results showed that the risk of death was 30% lower with atezolizumab plus bevacizumab compared with sorafenib, and 26% lower compared with lenvatinib. These trends were consistent across White, Black, and Hispanic patients. Thus, patients who received atezolizumab plus bevacizumab had improved survival outcomes compared with those treated with sorafenib or lenvatinib, regardless of race or ethnicity. Background/Objectives: This study evaluated comparative overall survival (OS) of United States veterans with unresectable hepatocellular carcinoma (uHCC) receiving first-line (1L) atezolizumab plus bevacizumab vs. sorafenib or lenvatinib, overall and across racial and ethnic groups. Methods: In this retrospective study, patients with uHCC who initiated atezolizumab plus bevacizumab (post-2020) or sorafenib or lenvatinib (post-2018) were identified from the Veterans Health Administration National Corporate Data Warehouse (1 January 2017–31 December 2022). Patient characteristics were evaluated in the year prior to 1L treatment initiation. Kaplan–Meier and multivariable Cox regression methods were used to compare OS starting from treatment between cohorts, both overall and by race and ethnicity. Results: Among the 1874 patients included, 405 (21.6%) received 1L atezolizumab plus bevacizumab, 1016 (54.2%) received sorafenib, and 453 (24.2%) received lenvatinib, with a median follow-up time of 8.5, 7.6, and 8.2 months, respectively. Overall, patients receiving atezolizumab plus bevacizumab had longer unadjusted median OS (12.8 [95% CI: 10.6, 17.1] months) than patients receiving sorafenib (8.0 [7.1, 8.6] months) or lenvatinib (9.5 [7.8, 11.4] months; both log-rank p < 0.001). After adjustment, atezolizumab plus bevacizumab was associated with a reduced risk of death by 30% vs. sorafenib (adjusted HR: 0.70 [95% CI: 0.60, 0.82]) and by 26% vs. lenvatinib (0.74 [0.62, 0.88]; both p < 0.001). OS trends in the White, Black, and Hispanic patient cohorts were consistent with that of the overall population. Conclusions: Atezolizumab plus bevacizumab was associated with improved survival outcomes compared with sorafenib and lenvatinib in patients with uHCC, both overall and across racial and ethnic subgroups.
