Determining the organ at risk for lymphedema after regional nodal irradiation in breast cancer. Int J Radiat Oncol Biol Phys. 2019; 105: 649-658 Abstract Full Text Full Text PDF PubMed Scopus (29) Google Scholar our study focused solely on patients who received regional nodal irradiation for lymph-node positive breast cancer. The results of our study indicate that in this patient population, the most important factors associated with the development of breast cancer-related lymphedema (BCRL) are number of lymph nodes removed/type of axillary surgery, body mass index, and age.
