A Case of Progressive Bleomycin Lung Toxicity Refractory to Steroid Therapy

Abstract

Bleomycin is a common chemotherapy agent used to treat germinative tumors. Bleomycin-induced lung injury (BILI) is an uncommon but devastating adverse effect of its use. It occurs in 10-20% of patients receiving bleomycin, and the initial diagnosis is usually made by new-onset respiratory symptoms and reduced diffusing capacity for carbon monoxide (DLCO). Mainstay treatment includes discontinuing bleomycin, corticosteroids, and supplemental oxygen if needed. We present a case of a 38-year-old male who was found to have a severe presentation of bleomycin-induced lung injury after chemotherapy for metastatic mixed germ cell testicular cancer. During his course, he was treated with the standard of care regimen of corticosteroids and salvage therapy with infliximab but ultimately died from complications of his illness. This case report is noteworthy because our patient had progressive bleomycin-induced lung injury, despite discontinuing bleomycin many months prior, consistent high-dose corticosteroid treatment, and even salvage therapy. In all patients on bleomycin, pulmonary function monitoring is essential, and any complaints of dyspnea should prompt concern for bleomycin-induced lung injury. If initial treatment does not improve their condition, more aggressive measures may be necessary.
