What dose constraints do you use for OARs when treating with breast IMRT?
Are you able to achieve the contralateral breast and lung V5 constraints from current protocols?
Answer from: Radiation Oncologist at Community Practice
We follow dose constraints from ongoing NRG studies of breast plus RNI with the only difference being, to focus more on dose homogeneity and make sure V 105 for ipsilateral breast is <10%, and mean heart dose of heart and LAD if possible, below 2 Gy.
