The article presents the changes in intestinal microbiocenosis in lung cancer patients, chemotherapy, the nature of the influence appointed in the schemes of the treatment of lung cancer, impact of anticancer drugs on the state of the intestinal microflora, and the improvement of technologies of treatment of lung cancer patients receiving chemotherapy on the basis of supplementation of the complex therapy by the probiotics Material and methods. 41 lung cancer patient receiving the first line of the first cycle of chemotherapy was included. The age of patients varied from 49 to 73 years, the average duration of the disease was 1 year. Patients from the main group (n = 21) received probiotics treatment together with the chemotherapy course. Patients from the control group (n = 20) received only chemotherapeutic preparations. All patients were observed before and after treatment, the study of metabolites of intestinal microorganisms in blood was performed by the method of the gas-liquid chromatography - mass-spectrometry by G.A. Osipov’s method, determination of cytokine status multiplex method. The efficiency of probiotic therapy was evaluated by results of the dynamics of studied indices. Results. The deterioration in intestinal microflora was manifested as the decreased quantity of Lactobacillus, Bifidobacterium, and increased quantity of different pathogenic microorganisms. It was noted decreased rate in the improvement of composition intestinal microflora after the treatment course with the metabiotic. Conclusion. Using of metabiotic medicines with the chemotherapy in lung cancer patients is promising to prevent deterioration of the gut microflora.lung cancerchemotherapyintestinal dysbiosisintestinal microbiotagas-liquid chromatography - mass spectrometry of microbe markersdetermination of cytokine status multiplex methodmetabioticкишечная микробиотаинтерлейкины кровирак лёгкогохимиотерапиямасс-спектрометрия микробных маркёровметабиотический препарат[Carding S., Verbeke K., Vipond D.T., Corfe B.M., Owen L.J.
