APPLICATION OF RADIOFREQUENCY ABLATION WHILE PERFORMANCE OF VIDEOTHORACOSCOPIC OPERATIONS FOR PULMONARY AND PLEURAL TUMORS

In the clinic radio—frequency ablation (RFA) in videothoracoscopic operations (VTHO) was performed in 56 patients. Primary peripheral pulmonary cancer (PC) was revealed in 7 patients, metastatic pulmonary affection — in 12, pleural affection with exudate — in 37. Small—cell PC was diagnosed in 11 patients, a squamous—cell one — in 18, and glandular — in 27. VTHO, using RFA technology, is indicated in primary or metastatic PC without possibility to perform radical intervention due to the process spread, patient's age, presence of severe concurrent diseases; refusal of patient from surgical treatment. Positive result was achieved in 54 patients. Duration of pleural drainage was 3 days at average, the patient stationary stay — 4 days. Insufficient experience of application of VTHO with RFA do not permit to estimate late follow—up results objectively. Yet, 25 patients, in whom metastatic pleurisy was revealed, have survived more than 9 mo, in peripheral PC one patient died as a result of pulmonary thromboembolism, and the rest of patients have survived from 1 yr to 1.5 yrs.
