What brachial plexus dose constraints do you apply when treating conventionally fractionated NSCLC?  

Yes. I am presuming you are discussing treating definitively with CRT for locally advanced NSCLC.Since RTOG 0617, most people that treat NSCLC prescribe to a dose of 60-66 Gy in 30-33 fx, as this is a feared toxicity that is very painful and decreases QOL. We try to keep the brachial plexus dose to ...

In this trial, they used a dose of 45 Gy/25# with cisplatin/etoposide, but one could go higher to a defi...

NCCN lists median brachial plexus dose constraint as < 69Gy for conventionally fractionated 30-35Fx regimen. (When I inquired a while back, they confirmed this wasn't a typo).
