Intraoperative radiotherapy by means of the compact betatron BM-10E as the treatment optimization method of the patients with soft tissues sarcomas

We have performed the retrospective research upon the follow-up study in the treatment of soft tissue sarcomas using intraoperative radiotherapyby means of the compact betatron ВМ-10Э (n = 171) in comparison with the group of combined therapy of adjuvant gamma-ray teletherapy (n = 57) and the group of surgical treatment. The using of intraoperative radiotherapy as the element of combined therapy is confirmed to improve the indices of 5-years overall (p = 0,025) and progression-free survival (p
