Gastrointestinal toxicity can occur following irradiation of thoracic, abdominal, or pelvic malignancies if gastrointestinal structures are located within the radiation therapy (RT) field. Dr Sudeshen Naidoo explains further.

The incidence and severity of RT side effects depend upon the site, volume of tissue exposed, and treatment schedule, including total dose, dose per fraction, and type of radiation. Other risk factors for radiation-induced GI toxicity include the use of concomitant chemotherapy. 1. Oesophagitis Normal oesophageal mucosa undergoes continuous cell turnover and renewal. Acute radiation oesophagitis is primarily due to effects on the basal epithelial layer. This causes a thinning  of…
