MULTIMODAL APPROACH IN THE TREATMENT OF PATIENTS WITH MALIGNANT PLEURAL LESIONS

The study includes data on 54 patients with pleural malignant lesions (39 with metastatic pleural malignant tumors and 15 with pleural malignant mesothelioma) received treatment using a multimodal approach: maximum cytoreduction, intraoperative photodynamic therapy and hyperthermic chemoperfusion of pleural cavity. A control group of patients with malignant pleural mesothelioma consisted of 21 patients who had undergone only conservative treatment. It was found out that the use two-thoracotomy surgical approach had advantages over standard thoracotomy across IV intercostal space. The use of multimodal treatment was accompanied by relatively low (1.85%) postoperative mortality on the background of a relatively high number (79.6%) of postoperative complications, easily cured in the early postoperative period. The use of multimodal therapy in treatment for metastatic pleural malignant lesions was accompanied by a median of disease-free survival of 11 months and a median of overall survival of 23 months. The proposed multimodal treatment compared with conservative methods of therapy improved disease-free (12 months vs. 7.5 months) and overall (18.8 months vs. 10.2 months) survival. Thus the use of a multimodal approach in treatment for pleural malignant lesions is relatively safe but requires further study.
