After Treatment for Gastrointestinal Stromal Tumors

For some people with a gastrointestinal stromal tumor (GIST), treatment can remove or destroy the cancer. You might be relieved to finish treatment, but it can be hard not to worry about cancer coming back. This is very common if you’ve had cancer.

For other people, the cancer might never go away completely. Some people might still get regular treatments to try to control the cancer for as long as possible. Learning to live with cancer that does not go away can be difficult, but many people find ways to manage their health and maintain a good quality of life.

No matter what your situation is, there are steps you can take to live well, both physically and emotionally.

Follow-up care

During and after treatment, it’s very important to go to all your follow-up appointments. During these visits, your cancer care team will watch for signs of a GIST coming back (recurrence), as well as any side effects of the treatments you’ve had.

Talk with your doctor about developing a survivorship care plan for you. This plan can guide your next steps after treatment, including follow-up appointments and ways to stay healthy.

What’s usually in a survivorship care plan

A survivorship care plan might include:

  • A summary of the diagnosis, tests done, and treatments given
  • A suggested schedule for follow-up exams and tests
  • A schedule for other tests you might need in the future, such as tests to look for long-term health effects from your cancer or its treatment
  • A list of possible late- or long-term side effects from your treatment, including what to watch for and when you should contact your health care team
  • Diet and physical activity suggestions
  • Reminders to see your primary care provider (PCP) for routine health care and cancer screening

What to expect during follow-up appointments

Follow-up visits often include careful physical exams and tests such as blood work or imaging, especially if you remain on targeted drugs in the years after a GIST is diagnosed. How often you follow up with your care team will depend on your cancer, its response to treatment, and other factors.

For example, almost any cancer treatment can have side effects. Some might last only a short time, but others can last longer or might not show up until months or years later. It’s important to report any new symptoms to your cancer care team right away, so that they can find a cause and treat it, if needed.

Questions to ask after treatment

  • Do I need a special diet after treatment?
  • Are there any limits on what I can do?
  • What other symptoms should I watch for?
  • What kind of exercise should I do now?
  • What type of follow-up will I need after treatment?
  • How often will I need to have follow-up exams and imaging tests?
  • Will I need any blood tests?
  • How will we know if the cancer has come back? What should I watch for?
  • What will my options be if the cancer comes back?

Late and long-term effects of treatment

Just as the treatment for GIST requires an individual approach, so does follow-up care after treatment.

People treated for GISTs can be at risk for several health problems after treatment. Your risk will depend on a few factors, including the types and doses of treatments you received.

It’s important to ask your cancer care team what health problems you might have, so you know what to watch for.

Adopting healthy behaviors such as not smoking, eating well, getting regular physical activity, and staying at a healthy weight might help prevent long-term health problems.

Potential health problems include:

When part of the GI tract must be removed to treat GIST, scar tissue can develop after surgery. This can cause narrowing or blockage of the intestines, which might cause nausea, vomiting, pain, bloating or changes in bowel habits.

If a large section of the bowels must be removed, this can sometimes lead to low levels of certain nutrients or vitamins.

Tyrosine kinase inhibitors (TKIs) can cause problems like high blood pressure, abnormal heart rhythm, and weakening of the heart muscle. Heart problems might first be noticed while taking the drugs.

If these problems are not recognized and managed, these might increase the risk of heart attacks or heart failure later in life.

Your cancer care team might do blood tests or imaging, such as an echocardiogram (an ultrasound of the heart) to help catch heart problems early.

TKIs can affect how the thyroid gland works. The cancer care team will monitor thyroid function with blood tests during and after treatment with these targeted drugs.

Thyroid hormone treatments can also be given, if needed.

Treatment with ripretinib (Qinlock), a tyrosine kinase inhibitor (TKI) used for some people with GIST, might lead to a higher risk of having skin cancer. Doctors might check the skin more regularly. Any skin changes or spots should be shared with your cancer care team right away, so that they can be evaluated and treated, if needed.

If the cancer comes back

If a GIST does recur, your treatment options will depend on:

  • Where the cancer is located
  • What treatments you’ve had before
  • Your overall health
  • Your treatment preferences

Social and emotional health after cancer

Once treatment is finished, a number of emotional concerns can come up.

Some of these might last a long time and can include:

  • Dealing with any physical changes that happen because of treatment
  • Worrying about the GIST returning or new health problems developing
  • Being treated differently or discriminated against by friends, classmates, coworkers, employers, and others

You might also feel:

  • Resentful for having had a GIST
  • Resentful for going through treatment when others didn’t have to
  • Guilty for surviving cancer when other friends with cancer did not

It’s normal to have some anxiety or other strong emotions after treatment, but feeling overly worried, depressed, or angry can get in the way of relationships, work, and other aspects of life.

With support from family, friends, other survivors, mental health professionals, and others, many people who have been treated for GISTs can thrive despite the challenges they’ve faced.

If your feelings are getting in the way of your daily life, consider reaching out for support. The American Cancer Society is here to help:
