[Respiratory complications of anticancer chemotherapy].

Pulmonary toxicity associated with chemotherapy is still rare, but its incidence may increase with intensive and iterative regimens. Following a review of the four main drugs responsible for lung toxicity (bleomycin, methotrexate, busulfan and BCNU), the authors underline the risk of combined chemotherapy and radiotherapy. To recognize, at an early stage, the signs suggesting lung toxicity is essential to reduce its extent and, above all, to exclude other pathologies which often have the same clinical and radiological features. Only histological studies provide evidence of toxicity. Treatment is frequently disappointing; the only hope of regression lies in withdrawal of the responsible drug and corticosteroid therapy.
