    What is the outlook for Gastrointestinal Carcinoid Tumors ?
    ### Response:
    Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following:         - Where the tumor is in the gastrointestinal tract.    - The size of the tumor.     - Whether the cancer has spread from the stomach and intestines to other parts of the body, such as the liver or lymph nodes.
