GIST Awareness Day: Shedding Light on Gastrointestinal Stromal Tumors

Every year on July 13th, GIST Awareness Day is observed to raise awareness about gastrointestinal stromal tumors (GIST). GIST is a rare type of cancer that affects the digestive system, specifically the gastrointestinal tract. Despite its rarity, it is important to understand the significance of GIST and promote awareness to support those affected by this condition. In this blog post, we will delve into the world of GIST, providing a comprehensive guide to help you understand the disease, its symptoms, diagnosis, treatment options, and the importance of GIST Awareness Day.

What is GIST?

Gastrointestinal Stromal Tumors (GISTs) are a type of soft tissue sarcoma that develops in the tissues of the gastrointestinal tract, which includes the stomach, intestines, and other parts of the digestive system. GISTs arise from a specific type of cell called the interstitial cells of Cajal (ICC), which regulate the movement of food through the digestive system.

Signs and Symptoms of GIST

GIST symptoms can vary depending on the tumor’s size, location, and stage. Some common signs and symptoms include:

  1. Abdominal pain or discomfort
  2. Feeling of fullness after eating small amounts of food
  3. Blood in stool or vomit
  4. Fatigue and weakness
  5. Unexplained weight loss
  6. Anemia


If GIST is suspected, your doctor may perform various diagnostic tests, including:

  1. Imaging tests: CT scans, MRI, or PET scans to visualize the tumor and determine its size, location, and spread.
  2. Biopsy: A sample of the tumor is obtained to confirm the diagnosis and assess its characteristics.
  3. Genetic testing: Mutational analysis is conducted to identify specific genetic mutations, such as mutations in the KIT or PDGFRA genes, which play a crucial role in GIST development.

Treatment Options:

Treatment options for GIST may include:

  1. Surgery: Surgical removal of the tumor is the primary treatment for localized GIST.
  2. Targeted therapy: Medications like imatinib (Gleevec), sunitinib (Sutent), and regorafenib (Stivarga) may be prescribed to block specific molecules that fuel tumor growth.
  3. Radiation therapy: In some cases, radiation therapy may be used to shrink the tumor before surgery or to treat GIST that cannot be surgically removed.
  4. Clinical trials: Participating in clinical trials can provide access to novel treatment options that are currently being studied.

GIST Awareness Day:

GIST Awareness Day plays a crucial role in raising awareness about this rare form of cancer. It serves multiple purposes, such as:

  1. Education: Promoting awareness helps educate the general public about GIST, its symptoms, and available treatment options.
  2. Support: GIST Awareness Day provides a platform for individuals affected by GIST to connect, share their experiences, and find support networks.
  3. Fundraising: Awareness campaigns often aim to raise funds for GIST research, which can help improve understanding and treatment options for this disease.

How Can You Get Involved?

There are several ways you can get involved and contribute to GIST Awareness Day:

  1. Share your story: If you or someone you know has been affected by GIST, consider sharing your experience to raise awareness and provide hope to others.
  2. Utilize social media: Spread the word about GIST Awareness Day on social media platforms using relevant hashtags, informational posts, and personal stories. You can find resources here.
  3. Participate in events: Attend or organize local events dedicated to GIST awareness to connect with others and support the cause.
  4. Donate to research organizations: Consider making a donation to research organizations focused on GIST, which can contribute to advancements in treatment and patient care.




GIST Awareness Day serves as an opportunity to shed light on gastrointestinal stromal tumors, a rare form of cancer that affects the digestive system. By understanding the signs, symptoms, diagnosis, and treatment options for GIST, we can support those affected by the disease and work towards improving outcomes and quality of life. Join the cause, spread awareness, and make a difference in the lives of individuals living with GIST. Together, we can make a positive impact on the journey towards a cure.
