One interesting study is called, "Pleural Space Perfusion With Cisplatin In The Multimodality

Treatment Of Malignant Mesothelioma: A Feasibility And Pharmacokinetic Study" - J Thorac Cardiovasc Surg 1999;117:759-765 by Giovanni B. Ratto, MD, Dario Civalleri, MD, Mauro Esposito, PhD , Elisabetta Spessa, MD, Antonella Alloisio, MD, Franco De Cian, MD, Maria O. Vannozzi, PhD - Here is an excerpt: "Introduction: Malignant pleural mesothelioma is an ideal model for testing new locoregional multimodality approaches because of its aggressive local behavior. Methods: This study was planned to investigate the feasibility, safety, and pharmacokinetics of a multimodality therapy including an operation, pleural space perfusion (60 minutes) with cisplatin (100 mg/m2), hyperthermia (41.5C), and postoperative radiotherapy (55 Gy to chest wall incisions). The effects of the extent of resection and perfusion temperature on cisplatin pharmacokinetics were evaluated. Ten patients with epithelial or mixed, stage I or II, malignant pleural mesothelioma underwent the following procedures: group A (3 patients), pleurectomy/decortication and normothermic pleural space antineoplastic perfusion; group B (3 patients), pleurectomy/decortication and hyperthermic perfusion; and group C (4 patients), pleuropneumonectomy and hyperthermic perfusion. Operations were selectively applied depending on tumor extent. Platinum levels were serially measured by atomic absorption in systemic blood, perfusate, lung, and endothoracic fascia. Results: The overall procedure was completed in every case, without any death or toxicity. No lung damage was demonstrated after treatment. Major complications included 1 wound infection and 1 diaphragmatic prosthesis displacement. The mean peak platinum plasma levels were reached within 45 to 60 minutes after perfusion was started. Systemic drug concentrations were greater after pleurectomy/decortication than after pleuropneumonectomy (P = .006). The local tissue/perfusate ratio of platinum concentrations tended to be higher after hyperthermic perfusion rather than normothermic perfusion. Conclusion: This multimodality approach is feasible, pharmacokinetically advantageous, and safe enough to undergo further clinical investigations."
