How do you manage a cT3bN0 endometrial cancer with large vaginal drop met s/p NAC and TAH/BSO with pCR?

I would offer EBRT plus brachytherapy. Also if distal vaginal mets, would add inguinal nodal region into the volume. If drop mets was not excised, would favor higher brachytherapy dose to the site of vaginal disease (EQ2 of 60 to 70 Gy).
