ObjectivesTo determine the frequency and grades of acute side effects with three-dimensional brachytherapy in carcinoma cervix using RTOG/EORTC acute radiation morbidity scoring criteria.Study DesignDescriptive study.Place And Duration Of StudyDepartment of Radiotherapy, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, Pakistan from July 2016 to September 2017.MethodologyA total of 55 histologically proven patients of squamous cell carcinoma of the cervix, aged between 16-70 years, were included. Patients with previous radiotherapy in pelvic area, inflammatory bowel diseases and known diabetics, were excluded. All patients were given a radiation dose of 7 Gray in 4 insertions through 3-dimensional conformal brachytherapy planning. Acute vaginal, gastrointestinal, and genitor-urinary side effects of brachytherapy were assessed.ResultsMean age of the patient population was 47.09 ±13.10 years (Range: 21-68). Mean time to presentation was 5.65 ±2.32 months and mean tumor size was 3.67 ±1.47 cm. Majority, i.e. 18 (32.7%) patient presented in stage III. Most of the patients, 26 (47.3%), had ECOG-2 performance status. Grade-1 genitourinary toxicity was significantly high (p <0.001). In lower gastrointestinal toxicity, Grade-1 was the highest being 54.5%. Conversely, vaginal toxicities of grade-2 and 3 were most commonly seen. Stratification of acute side effectswith respect toage, stage and tumor size revealed no significant association except in mucosal membrane toxicity, which was affected by tumor size (p = 0.004).ConclusionThree-dimensional brachytherapy in carcinoma cervix is a safe and tolerable procedure with minimal acute side effects. Key Words: Cervical cancer, Brachytherapy, Acute toxicities, Computed tomography.
