Research progress on the whole breast radiotherapy in prone position after breast-conserving surgery for early breast cancer / 中国辐射卫生

ABSTRACT

Whole breast radiotherapy after breast-conserving surgery for early-stage breast cancer increases local control rate and reduces postoperative recurrence. Compared to supine position, whole breast radiation therapy in the prone position provides dosimetric advantages and cosmetic outcomes in patients with large breasts. With the development of various radiotherapy techniques and tools, the radiation volume and dose for target and organs at risk (such as heart and lung) have changed. Models for the prediction of preferable treatment position in breast radiotherapy without the need for CT simulation and plan evaluation in both positions have been developed and implemented in radiotherapy practice. This paper briefly reviews the progression in the techniques and dosimetry of whole breast radiotherapy in prone position after breast-conserving surgery for early breast cancer.
