We investigated the efficacy of durvalumab consolidation and the incidence of radiation pneumonitis in patients who received concurrent chemo-radiotherapy (CCRT) for unresectable LA-NSCLC in a single institute.
Overall, 55.3 % of patients did not meet the criteria of the PACIFIC study; however, they still received consolidation durvalumab in real-world practice. Durvalumab consolidation was associated with favorable PFS in the total population as well as in the subgroup of patients who did not meet the criteria of the PACIFIC study. However, radiation pneumonitis occurred more frequently in the durvalumab group, especially within 3-6 months after CCRT. The incidence of grade 3 radiation pneumonitis was 14.3 % in the durvalumab group versus 2.5 % in the observation group.
Durvalumab consolidation was associated with favorable PFS in patients with LA-NSCLC in clinical practice. However, careful selection of candidates for durvalumab treatment and active surveillance and appropriate management for radiation pneumonitis are needed.
