title: Pharmacokinetics of VM 26 given intrapericardially or intravenously in patients with malignant pericardial effusion.
abstract: Three patients with lung cancer (1 SCLC, 2 NSCLC) and pericardial malignant effusion received 100 mg/m2 Teniposide (VM 26) i.v. and, 1 week later, 50 mg/m2 intrapericardially. Plasma, pericardial, and urine levels of the drug were measured in all patients after the two treatments by a HPLC assay. After intrapericardial administration, a high VM 26 concentration was found in the pericardial cavity and slow systemic drug absorption was observed. Since the drug AUC after intrapericardial administration was approximately 15-21 times that after i.v. administration, it could be that this treatment is more effective against neoplastic deposits localized in the pericardium. Even though this small series does not permit conclusions to be drawn on the efficacy of VM 26 given intrapericardially, the lack of local toxicity, minimal systemic toxicity, and the response observed in two out of three patients given intrapericardial VM 26 suggest that further investigation should be carried out on this method of VM 26 administration.
