Prevalence of medical conditions or comorbidities influencing first-line therapy in unresectable hepatocellular carcinoma in the United States.

Abstract

Introduction: Given treatment landscape changes, understanding the prevalence of medical conditions/comorbidities influencing real-world unresectable hepatocellular carcinoma (uHCC) treatment decisions is key for improving outcomes.

Patients and methods: In a retrospective chart review, physicians abstracted data from uHCC patients initiating first-line treatment (1L) between June 2020 and April 2022. Frequencies of medical conditions/comorbidities at 1L initiation were reported.

Results: Among 433 patients, 77% had Barcelona Cancer Liver Clinic (BCLC)-C and 37% had Child-Pugh B status. Overall, 51% had ≥ 1 condition/comorbidity making them potentially less suitable for a 1L immunotherapy combination regimen (e.g. atezolizumab plus bevacizumab), including upper/lower gastrointestinal bleeding risk (38%), chronic kidney disease (15%), history of thromboembolic events (12%), and autoimmune disorders (5%).

Discussion: More than half of the patients had ≥ 1 medical condition/comorbidity making them potentially less suitable for a 1L immunotherapy combination. This study provides timely insight into how immunotherapy combinations are being used in the real-world setting among a large number of patients.
