Introduction: The impact of radiation on the stomach after adjuvant radiotherapy for breast cancer is, however, little understood. While the stomach is thought to be generally safe to irradiate, we hypothesised that a number of factors that increase the risk of gastric illness in the Indian population. Materials and Methods: patients who underwent curative surgery for breast cancer followed by adjuvant RT were identified. To secure ≥ 5 years of follow-up, the cohort who underwent RT in 2012 was selected and followed until 2016 for development of gastric complications. Right and left breast cancers were identified using breast cancer codes: right breast(C50.*0) and left breast(C50.*1). Results: Of all the patients, 13.8% (20/144) patients developed gastricsymptoms: 16 patients suffered grade I toxicity (loss ofappetite, nausea), 8 patients with grade II toxicity (lossof appetite, nausea, vomit, lose weight ≤ 5%), and 1 withgrade III toxicity (loss of appetite, nausea, vomit, lose weight ≥ 5%). Conclusion: Dose limitation in stomach should be considered when the radiotherapyplan was formulated, especially for the patients treated with hypofractionated radiotherapy.
