The effect of local breast radiotherapy on circulating CD34(+) cells

Radiother Oncol. 2011 Aug;100(2):304-7. doi: 10.1016/j.radonc.2011.01.003. Epub 2011 Feb 11.

Abstract

The number of circulating CD34(+) (hematopoietic stem) cells (HSCs) was observed to decline by 15% in breast cancer patients after starting adjuvant radiation therapy, regardless of age or preceding chemotherapy. These data demonstrate that local radiation therapy can profoundly affect HSC homeostasis, which might have a myriad of important implications.
