Annals of Oncology 17: 372–379, 2006 • 10% of antineoplastic agents – pulmonary toxicity. • Diagnosis – history of drug exposure – the exclusion of other causes • infections,fluid overload, pulmonary edema, pulmonary embolism • lung involvement from the underlying neoplasm Pulmonary toxicity from antineoplastic agents • Interstitial lung disease (ILD) – the most common – interstitial lung damage, alveolar filling processes • • • • • non-specific interstitial pneumonitis hypersensitivity pneumonitis interstitial lung fibrosis BOOP ARDS, diffuse alveolar damage(hemorrhage) Interstitial Lung Disease • Many conditions that involve lung parenchyme – Alveoli, alveolar epithelium, capillary endothelium, interstitial space • Classification – Predominant inflammation and fibrosis – Predominant granulomatous reaction • Known and unknown cause • Nonmalignant disorder and are not caused by identified infectious agents – Precise pathway to fibrosis is not known Allergy 2000;55;1103-1120 • Basic aspects of the development of alveolitis – triggering of CD4 T cells by local antigen presenting cell – release of cytokines with multiple and overlapping functions – intra-alveolar and interstitial accumulation of alveolar macrophages , CD4+ T cells, CD8+ T cells, neutrophils Table 243–1.
