Eribulin-induced Interstitial Pneumonia: A Case Series and Retrospective Cohort Study

Eribulin is a chemotherapeutic agent used for advanced breast cancer, but there are some reports of eribulin-induced lung injuries. Three of our patients experienced eribulin-related lung injuries. Radiology revealed organizing pneumonia in two cases and diffuse ground-glass shadows indicative of hypersensitivity pneumonitis in the third. A retrospective survey of patients treated with eribulin at our hospital identified no other cases of eribulin-induced lung injuries. Overall, drug-related lung injuries occurred in 2.8% of our eribulin-treated patients, which is similar to the rates reported for other anticancer drugs. The findings from these three cases provide guidance for the safe use of eribulin.
