title: Hyperthermic pleural perfusion with cisplatin: early clinical experience.
abstract: BACKGROUND
  The preferred treatment for patients with pleural tumors or tumors with pleural extension has not been determined. Systemic and local modalities were studied, including intrapleural chemotherapy and hyperthermia, which mainly have been investigated separately. The objective of this study was to investigate the feasibility, toxicity and early results of a multimodality treatment consisting of surgery, chemotherapy, and hyperthermia in one session for the treatment of patients with pleural malignancies.
  
  
  METHODS
  From November 1994 to September 1998, 26 patients (7 patients with mesothelioma, 11 patients with thymic neoplasms, and 8 patients with other tumors) underwent intraoperative hyperthermic pleural perfusion (HPP). Perfusion was performed with a roller pump and a heat exchanger. Cisplatin was added when the temperature stabilized to a mean of 40.8 degrees C (range, 40.2-41.5 degrees C). Dosages of cisplatin used were 60 mg in 2 patients, 100 mg in 2 patients, 120 mg in 1 patient, 150 mg in 18 patients, and 200 mg in 3 patients. The patients underwent the following associated surgeries: extended extrapleural pneumonectomy in 8 patients, resection of tumor without pleurectomy in 4 patients, resection of tumors with pleurectomy in 10 patients, and exploration and HPP only in 4 patients (thoracotomy in 2 patients and video-assisted thoracoscopy in 2 patients).
  
  
  RESULTS
  There were no technical problems during the perfusion period. The systemic temperature rose to a maximum of 38 degrees C. There was no renal or hematologic toxicity, except in one patient who experienced thrombocytopenia. One patient died from complications related to a technical error. Eight patients had complications; the most bothersome were in four patients with empyema (early in two patients and late in two patients). The median postoperative hospital stay was 7 days (range, 2-50 days). Ten patients were alive 28-69 months after surgery. The overall 1-year, 2-year, and 3-year survival rates were 72%, 65%, and 44%, respectively. Complete ipsilateral pleuropulmonary control was achieved in 17 patients (9 patients who are alive and 8 patients who have died).
  
  
  CONCLUSIONS
  Intraoperative HPP with cisplatin is feasible, easy to perform, and relatively safe. This method may offer excellent local control for patients with pleural tumors.
