Bleomycin-associated pulmonary fibrosis: rapidly fatal progression without chest radiotherapy.
Two patients with carcinoma of the tonsil were treated with bleomycin (396 and 224 units, respectively) but not with radiotherapy. Respiratory insufficiency led to death 45 and 52 days, respectively, after onset of therapy. Chest radiographs before bleomycin therapy revealed no evidence for lung disease. Postmortem examinations showed severe interstitial and intraalveolar pulmonary fibrosis. Comparably rapid progression from radiographically normal pulmonary parenchyma to fatal fibrosis has been documented previously only in patients with thoracic neoplasia as well as, in all but one instance, either prior or concurrent chest radiotherapy. These two cases indicate that chest radiotherapy is not a necessary cofactor for the development of rapidly progressive, fatal, diffuse interstitial pulmonary fibrosis after bleomycin therapy.
