How do you decide between high tangents or regional nodal radiation in patients with small, ER+ breast cancers who have a single positive sentinel node?

I tend to look at factors such as age, LVSI as well as number of SLN (1/1 vs. 1/2,3,4).

After lumpectomy, for cases like this, my bias is to offer whole breast and RNI. I have also started offering more 40/15 to breast and lymph nodes so this approach doesn't lengthen course of treatment as compared...

There is wide variation in practice and to standardized across our network we follow guidelines as published by us
