GISTs are rare tumours that grow in the wall of the digestive tract, most often the stomach. They are treated by precise surgical removal — frequently by keyhole surgery — and, when needed, highly effective targeted (oral) therapy.
| Definition | Tumour arising in the wall of the GI tract |
| Common site | Most often the stomach, then the small intestine |
| When to see a surgeon | A submucosal mass found on endoscopy, bleeding, or a known GIST |
| Curative option | Surgical removal (often laparoscopic) ± targeted therapy |
What is a GIST?
A gastrointestinal stromal tumour (GIST) arises from specialised pacemaker cells in the wall of the digestive tract. Unlike common cancers that start in the lining, GISTs grow within the wall itself. Most occur in the stomach, and they range from small, incidental lesions to larger tumours that need treatment.
Symptoms & diagnosis
Small GISTs are often found by chance during endoscopy for another reason. Larger ones can cause bleeding (sometimes seen as anaemia or black stools), vague abdominal discomfort or a feeling of fullness. Diagnosis uses gastroscopy, endoscopic ultrasound (EUS) with biopsy, and CT for staging.
Treatment options
The main treatment for a localised GIST is precise surgical removal with a clear margin, frequently achievable by keyhole (laparoscopic) surgery for tumours in suitable locations. For larger, higher-risk or advanced GISTs, targeted oral therapy (tyrosine-kinase inhibitors) is remarkably effective and may be used before or after surgery.
Why precise surgery matters
GISTs should be removed intact with a clear margin while avoiding rupture, as careful technique strongly influences outcome. Combining experienced surgery with modern targeted therapy gives excellent long-term results.

GISTs are tumours with a range of behaviours from low to high risk. Localised GISTs are usually cured by complete surgical removal.
Yes. Many GISTs, particularly in the stomach, can be removed laparoscopically with a clear margin, offering quicker recovery.
GISTs often respond to targeted oral medicines (tyrosine-kinase inhibitors), which can shrink tumours before surgery or reduce recurrence after it.
Endoscopic ultrasound (EUS) with biopsy characterises the tumour within the gut wall, and CT scans assess its size and spread.
GIST (gastrointestinal stromal tumour) is treated primarily by surgery, sometimes combined with targeted drug therapy. Dr. Avinash Tank treats GIST at Dwarika Hospital, Ahmedabad.

Haan, surgery hi primary treatment hai, kabhi kabhi targeted drug therapy ke saath combine kiya jaata hai.
