RESUMO
For treatment of metastatic lung lesions there was used the method isolated chemoperfusion of the lung in combination with metastasectomy. The study includes 74 patients with metastases in the lungs who underwent 101 normothermal isolated chemoperfusion of the lung: of these 38 (37,6%) with melphalan and 63 (62,4%) with cisplatin without lethality. In the early postoperative period 1 (1,4%) patient died due to postperfusion lung edema. The period of observation of patients ranged from 2 to 99 months (median 29.3 months). Of 74 patients 53 (71,6%) patients are alive, 2 (2,7%) patients died from causes unrelated to the underlying disease. 43 (58,1%) patients showed progression of disease, what in 18 (41,9%) of them was the cause of death. Repeated appearance of metastases in perfused lung was detected in 30 (40,5%) patients. A 5-year disease-free (in the lungs) and observed survival of patients after isolated chemoperfusion of the lung with metastasectomy was 45% (median 46 months) and 59% (median not reached) respectively. There were established predictors of effectiveness of isolated chemoperfusion of the lung with metastasectomy: DFI> 13 months, ≤5 metastatic nodes in the lungs, the size of the largest metastasis in the lungs ≤20 mm, intralobular location of metastases in the lungs as well as the time of doubling the volume of metastases >64 days for chest computed tomography.
