Description
Summary:	Aim – assessment of the effectiveness of complex therapy to reduce the development of early cardiovascular complications. Materials and methods. Information from medical histories and outpatient follow-up cards of 139 patients with invasive breast cancer was analyzed: in the G.V. Bondar Republican Cancer Center 64 patients (main and control groups); as an additional comparison group, the study included 75 patients of the Samara Regional Clinical Oncology Dispensary. Patients in the control group (33 people) and the Samara Regional Clinical Oncology Dispensary group (75 people) received standard therapy (RUSSCO, recommendations, 2023): doxorubicin 60 mg/m2 IV on day 1 + cyclophosphamide 600 mg/m2 IV on day 1 Day 4 – 4 courses. In 31 patients of the main observation group, in addition to similar drug treatment, in order to prevent the development of early cardiovascular complications, the method was used, which included 7 courses before the start of 1 cycle of chemotherapy + 3 courses of interval normobaric hypoxic therapy (INHT) before the start of each subsequent cycle of chemotherapy. Results. When analyzing the total effectiveness of treatment between the groups of patients, statistically significant differences were obtained: the control and main groups were compared (χ2=5.4, p=0.03), the group of the Samara Regional Clinical Oncology Dispensary group and the main group (χ2=3.45, p=0.076). Conclusions. Hypoxic therapy significantly affects the quality of life of patients. For all indicators reflecting quality of life, traditional treatment was inferior to combination drug therapy with INHT.
