The GIST Patient Guide: Navigating Gastrointestinal Stromal Tumors

At a Glance

A gastrointestinal stromal tumor (GIST) is a rare soft tissue sarcoma of the digestive tract. Because of its rarity, it requires specialized care from a sarcoma expert. Key steps after diagnosis include genetic testing, understanding your pathology risk score, and discussing targeted therapies.

Receiving a diagnosis of a Gastrointestinal Stromal Tumor (GIST) can feel isolating, especially since it is a rare type of cancer that most people have never heard of. Unlike more common cancers of the digestive tract, GIST is a soft tissue sarcoma that requires specialized testing, unique risk scoring, and targeted treatments.

This guide was created to help you understand your diagnosis, translate the medical jargon on your pathology report, and empower you to have highly informed conversations with your medical team. Because GIST is rare, knowledge is your best advocacy tool.

Common questions in this guide

What is a gastrointestinal stromal tumor (GIST)?
GIST is a rare soft tissue sarcoma that develops in the digestive tract. Unlike more common gastrointestinal cancers, it arises from specific cells in the gut wall and requires specialized testing and unique treatments.
Why is it important to see a specialist for a GIST diagnosis?
Because GIST is a rare cancer, many doctors may not see it often. A sarcoma specialist or a multidisciplinary sarcoma tumor board has the expertise needed to correctly interpret pathology and recommend targeted therapies.
How is a gastrointestinal stromal tumor treated?
The primary treatments for GIST include surgical removal of the tumor and targeted therapies, such as the drug imatinib. Treatment plans depend heavily on the tumor's specific genetic mutations and risk score.
What should I ask my doctor after a GIST diagnosis?
You should ask your doctor how many GIST cases they treat each year, whether your case will be reviewed by a multidisciplinary sarcoma board, and what the immediate next steps are for your treatment plan.
