Which specialist treats gastrointestinal stromal tumour?

Gastrointestinal stromal tumour, or GIST, is a tumour arising in the digestive tract or nearby tissues. A pathologist confirms the diagnosis from tissue and may assess molecular features. A specialist radiologist interprets scans to show the tumour's position and extent. An experienced surgical oncologist may remove a localised tumour, while a medical oncologist advises about targeted therapy before or after surgery, or when the tumour cannot be removed. Complex cases are often discussed by a multidisciplinary team.

Ask your gastroenterologist, surgeon or family doctor for referral to a centre with sarcoma or GIST experience. Bring scan reports, biopsy results and medicine details. Ask whether surgery is suitable, whether targeted therapy is needed, and how imaging will check the response. The right sequence depends on tumour size, location, spread and your general health.

Arrange medical assessment for blood in the stool, persistent abdominal pain, ongoing fullness or unexplained weakness. Seek emergency help for severe abdominal pain, vomiting with a swollen abdomen, fainting or heavy bleeding. These symptoms can arise from several conditions, but urgent assessment is needed when they are severe or sudden.

Ask who is coordinating your care, whether the pathology confirms GIST, what molecular testing shows, whether surgery or targeted therapy comes first, and how scans will be scheduled. Ask which symptoms require same-day advice and how treatment may affect eating or bowel function.
