SUMMARY
Objective. To determine an optimal term of the neoadjuvant targeted therapy (NATTH) conduction in treatment of patients, suffering localized reno-cellular carcinoma (LRCC).??terials and methods. Into the randomized prospective investigation 24 patients, suffering clear-celled LRCC (?1?-2bN0M0), who were divided into two Groups, were included: the 1-st Group - 12 patients, to whom two blocks of NATTH (peroral pazopanib 800 mg daily during 28 days) were conducted; and the 2-nd Group - 12 patients, to whom four blocks of NATTH were conducted.Results. Stabilization of the process (in accordance to RECIST 1.1 scale) was registered in 9 (75%) patients of the 1-st Group and in 8 (67%) - of the 2-nd Group, while a partial answer - in 3 (25%) and 4 (33%) patients, accordingly (?2= 0.2; ? = 0.65). The medians of tumoral regression in the 1-st and 2-nd Groups were comparable: 18 [2; 27] and 17 [2; 34]%, accordingly. Statistical difference between the adverse effects rate in accordance to the CTC AE scale Degrees 1 - 4, performance of nephrectomy, ?ntra- and postoperative complications and duration of the hospital stay in the Groups compared was absent (? > 0.05).Conclusion. An optimal term for the NATTH conduction in patients, suffering LRCC, is application of two blocks. More durable NATTH leads to enhancement of cost of the treatment without further regress of LRCC, what do not impact the choice of the surgical treatment tactics.
