Three separate points to make:
1. Z-11 is often misquoted.
The Z-11 trial did not randomize patients to plus or minus nodal radiation. That question was asked in the MA 20 study.
In the MA 20 study, as well as a few other studies, the addition of regional radiation provides a meaningful impact on ou...

My understanding of this literature is very similar to @Dr. First Last, whose answer I wholeheartedly support.

Z-11 asked and answered a surgical question. In clinically node (-) women with 1-2 + SLNs, there was no benefit to ALNDx. Some people note that in Z-11 the regional nodal recurrence rate was...

Since this has been adopted as standard of care by breast surgeons and ASCO guidelines, this would be norm rather than the exception. Even though not required in the Z 11 protocol, some radiation oncologists did modify field treated including variable nodal volume which makes data interpretation dif...

I agree with @Dr. First Last, in general. Where I struggle is when to add the superclav field. For micro mets, I never do, but even if technically a macro met (2mm), if the MRI didn't demonstrate any other obvious positive nodes, I may still just use high tangents.

The new question today is, given ...

It may be worth mentioning that the radiation field designs from the ACOSOG Z0011 trial were recently reported:

The ACOSOG Z0011 article doesn't really address the question on whether nodes were treated. When you look at radiation therapy treatment planning books, the axillary targets often will extend to the humerus. High tangents were described as up to within 2 cm of the humerus.

This is the trial that gave me the comfort of treating patients with +SLN with RT without an axillary dissection.
