4.1 Treatment for small stomach GISTs

Chart 4.1

maps the treatment options for GISTs

of the stomach that are smaller than 2 cm. Many of

these tumors are not cancer (benign). However, some

will grow fast and will become a problem.

Your doctors will assess the tumor for risk factors that

suggest there is a high risk for fast growth. Tumors

that aren’t high risk don’t need treatment. Instead, the

tumor can be looked at with an endoscope every 6 to

12 months for changes. Talk to your doctors about the

benefits and dangers of such testing.

Surgery to remove the tumor is recommended for

those that are at high risk of growing fast. After

surgery, you may get CT scans with contrast of your

abdomen and pelvis. CT scans every 3 to 6 months

for 3 to 5 years is recommended. If test results are

normal for 3 to 5 years, CT may be done every year.
