What affects the gastrointestinal carcinoid tumors treatment?

The prognosis (chance of recovery) and treatment options depend on the following:

Whether the cancer can be completely removed by surgery Whether the cancer has spread from the stomach and intestines to other parts of the body, such as the liver or lymph nodes The size of the tumor Where the tumor is in the gastrointestinal tract Whether the cancer is newly diagnosed or has recurred

Treatment options also depend on whether the cancer is causing symptoms. Most gastrointestinal carcinoid tumors are slow-growing and can be treated and often cured. Even when not cured, many patients may live for a long time.

This answer is based on information from the National Cancer Institute.
