There are few reports on the effectiveness of corticosteroids for immune checkpoint inhibitor-induced interstitial pneumonia in patients with a history of interstitial pneumonia. We report on 10 non-small cell lung cancer patients with a history of interstitial pneumonia who experienced immune checkpoint inhibitor-induced interstitial pneumonia. The immune checkpoint inhibitor-induced interstitial pneumonia lasted for a median duration of 41.5 days (range = 22–127 days). Eight of the ten patients responded to corticosteroid monotherapy; one patient responded to corticosteroids and the immunosuppressant, tacrolimus; and one patient did not improve after corticosteroid treatment. In non-small cell lung cancer patients with a history of interstitial pneumonia, immune checkpoint inhibitor-induced interstitial pneumonia was generally responds to corticosteroids.
