Completion Rates for Patients Undergoing Concurrent Chemoradiotherapy for Stage III Nonsmall Cell Lung Cancer and its Importance in the Era of Consolidation Immunotherapy: A Cohort Study

Abstract

Background: Definitive concurrent chemoradiotherapy (CRT) is the primary curative-intent treatment option for unresectable locally advanced nonsmall-cell lung cancer (NSCLC). Completion of CRT is generally required for eligibility for consolidation durvalumab, which significantly improves survival. We sought to establish CRT completion rates at a comprehensive cancer center. Patients and Methods: 265 patients were treated with concurrent CRT over the decade 2012-2022, during which durvalumab became available. 63% were male, median age was 67, and 91% had performance status 0-1. All patients were recruited into the AURORA prospective cohort study which captured baseline demographics and comor..
