What hypofractionated regimens would you consider for postoperative SCC of the hand with a positive margin?

I have started to use 50 Gy in 20 fractions in all patients with a recent retrospective analysis from Australia for cutaneous squamous and basal cell cancers that has been used for head and neck patients, another sun-exposed site with cosmetic concerns. This type of question is hard to answer as man...

50 in 20 is fine. If its location could be readily salvaged without compromising form or function, observation is also ok. It’s unusual to not clear margins in the hand. Suspect proximity to a joint that the surgeon couldn’t get any deeper, and as such, treatment is very justified.
