Three or Four Fractions of 4-5 Gy per Week in Postoperative High-Dose-Rate Brachytherapy for Endometrial Carcinoma

Three fractions of 4-5 Gy in 3-5 days after EBI or 6 fractions in <15 days in patients receiving HDRBT alone was a safe treatment in relation to toxicity and local control. Vaginal surface BED less than 75 Gy after EBI and less than 160 Gy in HDRBT alone may be safe to avoid G2 toxicity.
