| Summary: | Abstract Background Durvalumab following concurrent chemoradiotherapy is standard treatment for unresectable stage III non‐small‐cell lung cancer based on the results of the PACIFIC trial. Based on trial criteria, not all patients are eligible for durvalumab in routine clinical practice. Methods We evaluated eligibility for durvalumab in a real‐world clinical setting and the impact of eligibility on outcomes. Consecutive patients treated with concurrent chemoradiotherapy at two tertiary centers between January 2015 and June 2022 were assessed. Clinical characteristics and outcomes were evaluated based on eligibility criteria for the PACIFIC trial. Results A total of 126 patients were included. Seventy patients (56%) were eligible for durvalumab. Ineligibility was associated with shorter progression‐free survival of 9.7 months versus 18.4 months (hazard ratio [HR] 0.61, 95% confidence interval [CI] 0.39–0.95, p = 0.029) and overall survival of 26.4 months versus 58.7 months (HR 0.47, 95% CI 0.28–0.80, p = 0.005). Common reasons for ineligibility were history of previous malignancy (32%) and progressive disease or death during chemoradiotherapy (25%). Ineligible patients who received durvalumab had similar outcomes to eligible patients who received durvalumab. Conclusions In a real‐world cohort, adjuvant durvalumab is safe and beneficial in a substantial proportion of patients who would not have been eligible for the PACIFIC trial. |
