Molecular-targeted therapy has brought about an era of precision medicine, and immune checkpoint inhibitors have brought hope for a cure for advanced NSCLC. In the wake of this remarkable advancement, lung cancer with comorbid interstitial pneumonia (IP) has been completely left behind, as most clinical trials exclude patients with comorbid IP. IP, especially idiopathic pulmonary fibrosis (IPF), is often accompanied by lung cancer, and acute exacerbation can develop during various cancer therapies, including surgery, radiotherapy and pharmacotherapy. In this review, we focus on the clinical questions concerning pharmacotherapy in cases of advanced lung cancer with comorbid IP and discuss what we can do with the currently available data. en-copyright= kn-copyright= en-aut-name=IchiharaEiki en-aut-sei=Ichihara en-aut-mei=Eiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Medical Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=lung cancer kn-keyword=lung cancer en-keyword=interstitial pneumonia kn-keyword=interstitial pneumonia END
