Lung dose has been correlated with radiation pneumonitis, and V20 Gy ≤20% has been associated with significantly lower incidence of radiation pneumonitis (104). However, achieving an ipsilateral lung V20 Gy ≤20% can be difficult when IM nodes are targeted. Symptomatic radiation pneumonitis is rare with ipsilateral lung V20 Gy <30% (105,106). Ipsilateral lung dose-volume constraints of V20 Gy ≤20% and V20 Gy ≤30% are commonly accepted in breast treatment planning (107).
