A recent study I read on this same question regarding sentinel node biopsy (SNB) performed after melanoma wide excision found that the sentinel node could still be found just fine. And I have found that in practice a number of times when I wide-excised obvious melanomas at first presentation visit. ...

I agree, WLE can be followed by SLN Bx if melanoma data applies (and I think it does).

There is also support for local XRT to the general area following excision.
