Abstract:
Relevance: early breast cancer is detected in more than 60% of cases. Maintaining the quality of life of patients with early breast cancer at the highest possible level is a priority, along with the treatment of patients. Under a complex antitumor treatment as well as after its completion, more than 60% of patients with early breast cancer report the occurrence of functional disorders.An important aspect is to improve the effectiveness of the rehabilitation process of patients with early breast cancer taking into account scientifically-based and proven recommendations.Objective: to evaluate the event-free survival rate (EFS) of patients with EBC undergoing rehabilitation within a biopsychosocial approach.Materials and methods: 228 patients with breast cancer who received complex treatment from 2015 to 2019 were included in the study. The prospective part of the study included 114 patients with early breast cancer undergoing rehabilitation measures within the biopsychosocial approach. The control group which was selected retrospectively, using the method of "pairwise selection", included 114 patients with early breast cancer comparable in age, stage of the disease, volume of surgical treatment and menopausal status, undergoing physical and psychological rehabilitation prescribed by a doctor. Patients in both groups were stratified depending on preoperative chemotherapy. EFS was calculated over a 2-year follow-up period. Events that were censored were a disease progression, the appearance of metastases, the occurrence of another cancer, a new concomitant disease, an exacerbation of the concomitant pathology and death.Results: Rehabilitation measures within the biopsychosocial model improve the indicators of EFS in the group of patients with EBC: EFS was 18.3 months against 14.5 months in the control group (HR=0.91, 95% CI [0.83; 0.99]; p=0.0034). In a multi-factor analysis the key factors affecting EFS were neoadjuvant chemotherapy (HR=0.79, 95% CI [0.69; 0.94] ; p=0.0025), age (HR=0.87, 95% CI [0.71;1.09]; p=0.0027) and menopausal status (HR=0.85, 95% CI [0.84; 0.95] ; p=0.0022) (table 1). Conclusions: Rehabilitation measures within the biopsychosocial model improve the indicators of EFS in the group of patients with early breast cancer, the key factors affecting EFS were neoadjuvant chemotherapy, age and menopausal status.
