Efficacy and Safety of Intraoperative Radiotherapy in Breast Cancer: A Systematic Review
Cet article passe en revue la littérature (15 études) sur l'efficacité et la sécurité d'une radiothérapie per-opératoire pour le traitement d'un cancer du sein de stade précoce
The objective of this study is to assess the efficacy and safety of intraoperative radiotherapy (IORT) for early breast cancer through a systematic review. Fifteen studies met the inclusion criteria. Most studies assessed the combined treatment with IORT (10-24 Gy) and external beam radiotherapy (EBRT) (45-50 Gy) on early stage breast cancer (T0-2). Local control was over 95% for one and four years of follow-up and the 5-year overall survival was 99%. The TARGIT-A study found a similar survival comparing IORT with standard treatment. The incidence of acute and chronic complications was scarce. IORT is well tolerated by patients and acute and late toxicities are low. There are no differences in survival for IORT treated patients versus standard treatment.
