Gastrointestinal bleeding/ulcer among paediatric cancer patients after proton beam therapy.
This study analyzed 124 patients who underwent proton therapy with gastrointestinal tract involved in the irradiated field. The study reported gastrointestinal bleeding/ulcer occurred in 4 patients (3.2%), with no death due to the bleeding/ulcer. The authors suggested that upper gastrointestinal irradiation in older children undergoing intensive chemotherapy may increase the risk of developing gastrointestinal complications.
