Abstract

Osimertinib (AZD9291) is a third‑generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor approved for EGFR‑T790M‑positive non‑small cell lung cancer. A high incidence of interstitial lung disease (ILD) during combination treatment with osimertinib and anti‑programmed cell death‑ligand 1 (PD‑L1) inhibitor has been reported. The current study presents a case of ILD develo­pment during osimertinib treatment following nivolumab (an anti‑PD‑1 antibody) treatment. The 59‑year‑old female was diagnosed with stage IV lung adenocarcinoma harboring a deletion in exon 19 of the EGFR gene. Following nivolumab as a sixth‑line treatment, an EGFR‑T790M‑encoding mutation in EGFR exon 20 was identified by re‑biopsy. Osimertinib was therefore initiated as a seventh‑line treatment. A partial response was subsequently noted; however, 63 days after initia­tion of the treatment the patient presented with dyspnea with decreased oxygenation in the absence of fever and sputum. A computed tomography scan revealed the emergence of ground‑glass opacities with bronchiectasis in both lungs, and a diagnosis of ILD due to osimertinib was made. Following steroid pulse therapy with discontinuation of osimertinib, the patient's chest findings and respiratory condition improved. Therefore, it is considered that anti‑PD‑1 therapies may be associated with a risk of ILD during subsequent osimertinib treatment.
