РАНДОМИЗИРОВАННОЕ ИССЛЕДОВАНИЕ ЭФФЕКТИВНОСТИ ПРЕДОПЕРАЦИОННОЙ ФОТОДИНАМИЧЕСКОЙ ТЕРАПИИ ПРИ ИСХОДНО НЕРЕЗЕКТАБЕЛЬНОМ (НЕОПЕРАБЕЛЬНОМ) НЕМЕЛКОКЛЕТОЧНОМ РАКЕ ЛЁГКОГО

The authors made a prospective randomized comparison of results of preoperative photodynamic therapy (PhT) with chemotherapy, preoperative chemotherapy in initial unresectable central non-small cell lung cancer in stage III. The efficiency and safety of preoperative therapy were estimated as well as the possibility of subsequent surgical treatment. The research included patients in stage IIIA and IIIB of central non-small cell lung cancer with lesions of primary bronchi and lower section of the trachea, which initially were unresectable, but potentially the patients could be operated on after preoperative treatment. The photodynamic therapy was performed using chlorine E6 and the light of wave length 662 nm. Since January 2008 till December 2011, 42 patients were included in the research, 21 patients were randomized in the group for photodynamic therapy and 21 — in group without PhT. These groups were compared according to their sex, age, stage of the disease and histological findings. After nonadjuvant treatment the remissions were reached in 19 (90%) patients of the group with PhT and in 16 (76%) patients without PhT and all the patients were operated on. The explorative operations were made on 3 patients out of 16 operated on in the group without PhT (19%). In the group PhT 14 pneumonectomies and 5 lobectomies were perfomed opposite 10 pneumonectomies and 3 lobectomies in group without PhT. The degree of radicalism of resection appears to be reliably higher in the group PhT (RO– 89%, R1–11% as against RO–54%, R1–46% in group without PhT), p=0,038. The preoperative endobronchial PhT conducted with chemotherapy was characterized by efficiency and safety, allowed the surgical treatment and elevated the degree of radicalism of this treatment in selected patients, initially assessed as unresectable.
