metastasis: a single center evaluation in University Hospital of Düsseldorf

Reviewer's report:
Glad to see that all the suggestions I have previosly provided to the Authors have
been taken into account.
After the revision the paper is well written, interesting and intelligible.
I recommend it for publication in the Journal.
Just one question: is the title correct? in my opinion "the potential RISK of
contralateral non-sentinel groin node metastasis ...... etc" should be more
appropriate... please check.
