Noncardiogenic pulmonary edema (NCPE) is a rare and less well-recognizable pulmonotoxic syndrome of anticancer therapy than pneumonitis/fibrosis. NCPE is a clinical syndrome characterized by simultaneous presence of severe hypoxemia, bilateral alveolar infiltrates on chest radiograph, and no evidence of left atrial hypertension/congestive heart failure. The diagnosis of drug-related NCPE relies upon documented exclusion of any infectious, metabolic, or cancer-related causes.

INTRODUCTIONSeveral cancer therapeutic drugs are known to induce pulmonary damage, which may result in a variety of clinicopathologic syndromes with minor to severe clinical consequences [1]. Clinical syndromes associated with drug-induced pulmonary toxicity include pneumonitis/fibrosis, hypersensitivity lung disease, and noncardiogenic pulmonary edema (NCPE)/acute respiratory distress syndrome (ARDS). These syndromes share a similar symptomatology but differ in regard to the time-relation to cancer treatment, the radiographic findings, the duration of pulmonary damage, and the long-term outcome [2]. Non-specific symptomatology of cough, progressive dyspnea, and often a low-grade fever alert clinicians confronted with the diagnostic challenge to recognize subclinical syndromes and differentiate fully developed drug-induced pulmonary reactions from lung injuries caused by infectious, cardiac, and neoplastic causes.
