We evaluated the impact of a course of interval hypobaric hypoxia (0.306 kg/cm2) on the development of Ehrlich ascites carcinoma (EAC) in mice. In the first series of experiments, the mice were subjected to hypoxic training over 10 days, and in the second series the hypoxic training was provided daily for 3 weeks, except for weekends. The tumor volume was analyzed using a caliper on day 16 (the terminal period). The weight of the mice was measured on day 0, and the final net weight was measured on day 22. The rate of cancer development in mice exposed to hypoxic training within the first 10 days decreased by 58%. Exposure to 3 weeks of hypoxic training showed no significant antitumor effect. Upon completion of the hypoxic training, the rate of tumor development increased, and at the end of the study, no significant differences in survival were found. Further research is needed to determine the optimal antitumor effect and duration of the course of interval hypobaric training.Keywords: Ehrlich ascites carcinoma (EAC), mice, hypobaric hypoxia, antitumor protection, leukocytes, leukogram ER -
