Objectives: The addition of pelvic radiotherapy to brachytherapy (EBRT-BT) in early-stage endometrial cancer is controversial and may cause unnecessary toxicity. The incidence of acute toxicity of EBRT-BT will have an impact on clinical decision and patient compliance but is currently poorly understood. This study compares the acute toxicities of EBRT-BT versus BT alone. Materials and Methods: Seventy-nine patients with FIGO Stage IA-II endometrial cancer who underwent adjuvant radiotherapy, (EBRT-BT or BT alone) from 2001 to 2011 were included in the study. Medical records of these patients were reviewed retrospectively and toxicity graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Patients were followed up for at least three months post-treatment to assess resolution of toxicity. Results: The mean age of the study group was 60.6 years. Median follow-up was four years. Forty patients received EBRT-BT. There was a 37% increase in Grade 1-3 diarrhea with the addition of pelvic radiotherapy (OR 18.67, p < 0.0005) and a 34% increase in lethargy (p < 0.0005). There was also an increased occurrence of genitourinary and skin toxicities. Two patients in the EBRT-BT group required hospitalisation for severe diarrhea and three patients were unable to complete the treatment. All acute toxicities had resolved by three months post treatment. Conclusion: EBRT-BT causes significantly more acute toxicities compared to BT alone. Patients should be informed of this during counselling.
