[Aclacinomycin; benefits for the treatment of malignant pleural effusion].

Abstract
A series of experiments with ACM was performed to evaluate the effect for local treatment of malignant pleurisy from the view points of (1) clinical response, (2) pharmacokinetics following intrapleural administration, and (3) pleural reaction. The results were as follows: (1) In 6 patients with malignant pleural effusion, ACM was intrapleurally administered at a dose of 40 mg. In 4 out of the 5 evaluable cases, an extreme decrease in the pleural fluid volume and suppression of reswelling were observed, including 2 cases found to be negative for tumor cells upon cytodiagnosis. (2) In 5 patients, the pharmacokinetics was studied by using compartment model. The clearance curves of ACM in pleural fluid were described by a two-compartment model. The mean half lives of initial phase and terminal phase were 0.78 hr, and 15.28 hr, respectively. The time to reach the maximal whole blood level was 1 to 2 hrs after pleural administration, followed by a slow decline. (3) The pleural reaction to ACM was studied in rabbits by scanning and transmission electron microscope. At a dose of 4 mg per kg of body weight, the shortened microvilli, the degenerated mesothelial cells and the disappearance of basement membrane were observed. On the basis of these findings, we suggest that ACM might be an agent of choice in the treatment of malignant pleurisy.
