  1. Institutional time trends observed for delivery of left-sided breast radiotherapy. A marked increase in both regional LN-RT, and the use of IMRT/VMAT, was observed during the period of our study. Although mostly used for treatments involving regional LN-RT, IMRT/VMAT also became a common delivery technique for left-sided breast or chest wall RT, due to presumed benefits for dose homogeneity and conformity
