Role of a 10-Gy boost in the conservative treatment of early breast cancer: results of a randomized clinical trial in Lyon, France.

Abstract

Delivery of a boost of 10 Gy to the tumor bed after 50 Gy to the whole breast following limited surgery significantly reduces the risk of early local recurrence, with no serious deterioration in the cosmetic result. Additional follow-up evaluation will be required to assess the long-term results.
