Other Diagnostic Studies
Endoscopic guided biopsy may be done for definite diagnosis of gastrointestinal stromal tumor. However, percutaneous biopsy is not routinely recommended.
- Patients with unresectable GIST must undergo biopsy to determine tumor cell type and chemotherapy.
- GISTs are highly vascular which puts them at a risk of bleeding.
- Percutaneous fine needle biopsy may put the patient at an increased risk of tumor rupture and bleeding.
- Percutaneous biopsy can also lead to tumor seeding along the biopsy tract such as peritoneum or mesentery.
- Thus, patients in whom surgery is an option are advised not to undergo biopsy.
