Gastrointestinal (GI) cancer refers to cancers that affect the digestive system, which includes:
Since "GI cancer" refers to a group of cancers affecting the gastrointestinal system, treatments vary by the specific diagnosis. Often, a combination of treatments is required for the best outcome. Compass Oncology GI cancer doctors will review your specific diagnosis, the stage of cancer, and other factors, such as biomarker test results, to select the most appropriate treatments. Usually, a few treatments are included in the plan, which is individualized for each patient.
At Compass Oncology, every GI cancer patient receives comprehensive care, including access to a surgical oncologist. Our multidisciplinary team of GI cancer specialist collaborate to develop a personalized treatment plan and determine whether the tumor is resectable (removable).
Biomarker testing for gastrointestinal (GI) cancer is performed to identify specific genes, proteins, or other substances that may be influencing the cancer’s growth. GI cancers with available biomarker tests include stomach cancer, pancreatic cancer, colon and rectal cancer, and esophageal cancer. If a biomarker is found in the tumor sample, a specific drug may be available to counteract it, slowing the growth of cancer. Your oncologist will discuss this with you as part of an overall treatment plan.
Only a small percentage (about 5-10%) of gastrointestinal cancers are hereditary. Certain conditions may increase the risk of developing GI cancer, including Lynch syndrome (also known as hereditary nonpolyposis colorectal cancer or HNPCC) and familial adenomatous polyposis (FAP).
If you or a loved one was diagnosed with a GI cancer, your oncologist at Compass Oncology will discuss genetic counseling and testing based on your family history. Hereditary cancer syndromes can influence treatment decisions and screening recommendations. Genetic testing and early screening may also benefit family members who wish to assess their own risk.
Gastrointestinal cancers can spread, or metastasize, to other parts of the body if they move beyond their original site. Distant locations where gastrointestinal cancers may spread include the lymph nodes, lungs, bones, peritoneum (the lining of the abdominal cavity), and, in some cases, the brain. Certain GI cancers, including colorectal cancer and pancreatic cancer, are known to spread to the liver. The location of metastasis can affect the symptoms you experience and the recommended treatment approaches.
The side effects of GI cancer treatment vary depending on the specific therapies you receive and how your body responds to them. Common side effects include fatigue, nausea, vomiting, abdominal pain, and bowel issues such as constipation or diarrhea. Some treatments, such as chemotherapy for colorectal cancer, may also cause numbness or tingling in the hands and feet. Learn more about the side effects of chemotherapy for colorectal cancer treatment.
Most people assume they will lose their hair with cancer treatment. However, not all drugs for GI cancers have this side effect. You may, however, experience hair thinning. Talk to your oncologist about the specific side effects of your drugs and if scalp cooling during treatment is recommended. Typically, hair grows back after treatment ends.
Clinical trials provide access to new treatment options for gastrointestinal cancers, allowing many patients to try innovative therapies or investigational drugs that aren’t yet available outside the study. This includes new targeted therapies designed for tumors with specific biomarkers.
Compass Oncology participates in several GI clinical trials through its partnership with Sarah Cannon Research Institute (SCRI). While not every patient is eligible to participate in a clinical trial, our team is here to guide you and make recommendations if you qualify. If you are considering a clinical trial, it is important to discuss your options with your oncologist.
