Breast sarcomas (BS) are the group of rare malignant tumors of the breast, the optimal treatment is still under discussion. Patients and methods. We retrospectively reviewed 51 patients with BS between 1999 and 2017 in National Medical Research Center of Oncology named after N.N. Blokhin. Results. Five-year recurrence-free survival and OS rate were 37,5 and 56,2%, respectively. With median follow-up of 86,4 months, 43,14% patients (22/51) were found with local recurrence and metastasis. Conclusion. Disease stage and local recurrence were indicated as unfavorable prognostic factors. Surgery remains crucial treatment for breast sarcomas. Mastectomy is not routinely necessary if clear margin could be achieved by local excision. The combined approach is necessary in the treatment of high-grade sarcomas, taking into account the morphological and immunohistochemical parameters of the tumor.
