Interstitial pneumonitis associated with dasatinib: two case reports and literature review

Dasatinib has increasingly been used to treat chronic myeloid leukemia (CML), although interstitial pneumonitis has been found as a complication in large clinical trials. In the present study, 23 patients received dasatinib for CML between 2012 and 2017 at our institution, of whom 2 developed symptomatic interstitial pneumonitis. Notably, the first patient developed interstitial pneumonitis five years after initiating dasatinib. Interstitial pneumonitis should be considered as a complication in patients receiving dasatinib for CML, which may even occur after a long period of uncomplicated administration.
