For vaginal cuff recurrence of an endometrial cancer, when do you utilize a multichannel cylinder versus single channel cylinder if a patient has <5 mm residual disease after EBRT?

If disease is confined to one wall, favor MC applicator as I treat vaginal wall thickness for side involved while surface on other side. MC allows that flexibility.
