What are the Symptoms of Gastrointestinal Stromal Tumors?

Gastrointestinal stromal tumors (GISTs) are a type of soft tissue sarcoma that can develop in the digestive tract, usually in the stomach or small intestine. Symptoms of gastrointestinal stromal tumors can vary based on the size, location, and growth rate of the tumor. Common symptoms may include:

  1. Abdominal Pain or Discomfort:
    • Persistent or recurrent pain or discomfort in the abdomen, often localized to the stomach area.
  2. Feeling Full or Bloated (Early Satiety):
    • A sensation of fullness or bloating, even after eating a small amount of food.
  3. Nausea and Vomiting:
    • Nausea and occasional vomiting, especially if the tumor obstructs the digestive tract.
  4. Blood in Stool or Vomit:
    • Presence of blood in the stool (which may appear dark or tarry) or vomiting blood.
  5. Fatigue and Weakness:
    • Persistent fatigue, weakness, or a general sense of tiredness.
  6. Unintentional Weight Loss:
    • Significant weight loss without a clear explanation or change in diet or physical activity.
  7. Difficulty Swallowing (Dysphagia):
    • Difficulty swallowing, especially if the tumor affects the esophagus or the upper gastrointestinal tract.
  8. Anemia:
    • Low red blood cell count, which may lead to fatigue, pale skin, and shortness of breath.
  9. Palpable Mass or Swelling:
    • A lump or mass that can be felt in the abdomen, particularly in the stomach area.
  10. Gastrointestinal Bleeding:
    • Bleeding within the gastrointestinal tract, which can manifest as dark or bloody stools or vomiting blood.
  11. Changes in Bowel Habits:
    • Changes in bowel movements, such as diarrhea or constipation.

GISTs may grow slowly or rapidly, and some may remain asymptomatic for a long time. It’s important to note that these symptoms can also be associated with various other gastrointestinal conditions. If you experience persistent or worrisome symptoms, seeking prompt medical evaluation and diagnosis is essential. Treatment for GISTs often involves surgery, targeted therapy, and sometimes other modalities like chemotherapy or radiation therapy, depending on the size, location, and stage of the tumor.
