Is There a Tradeoff in Using Modified High Tangent Field Radiation for Treating an Undissected Node-Positive Axilla?

Modified high tangent fields are necessary for definitive coverage of Ax1 and Ax2. This technique increases mean ipsilateral lung and heart doses as well as the V5, V10, and V20 of ipsilateral lung and the V25 and V30 of the heart. Risk of RP remains low by use of MHTF.
