Nintedanib is a multi‐target receptor tyrosine kinase inhibitor that reduces the decline in forced vital capacity (FVC) and prevents acute exacerbations in idiopathic pulmonary fibrosis (IPF), which is a risk factor for lung cancer. However, it remains unclear whether nintedanib is an effective treatment for lung cancer in patients with IPF. Here, we describe an 82‐year‐old man with non‐small cell lung carcinoma complicated by IPF who was treated with nintedanib. High‐resolution computed tomography (HRCT) showed a subpleural basal‐predominant reticular shadow and traction bronchiectasis with a honeycomb pattern. His FVC decreased over time, and his 6‐min walk test showed oxygen desaturation. Furthermore, an enlarged nodular lesion was detected after 6 months of referral. Biopsy confirmed non‐small cell carcinoma. Because of the risk of acute exacerbation of IPF by chemotherapy, supportive care was selected. Nintedanib was started as treatment for the IPF. Nine months later, HRCT revealed partial remission without exacerbation of IPF. This case indicates the possibility of nintedanib monotherapy in suppressing lung cancer complicated by IPF. Patients with lung cancer complicated by IPF in whom treatment is effective remain unknown. Additional research is needed to identify effective therapy for lung cancer with IPF.
