Treatment for gastrointestinal carcinoid tumors depends on factors like the tumor's location, size, whether it has spread, and the patient’s overall health. Here are the main treatment options:
- Surgery: This is the primary treatment method, especially if the tumor is localized. Surgery might involve removing the tumor alone or, in some cases, part of the affected organ.
- Endoscopic Mucosal Resection: Most frequently used to remove small carcinoid tumors of the stomach and duodenum (the first portion of the small intestine) and to remove small carcinoid tumors of the rectum.
- Local Excision: Removes the primary tumor and portions of the normal tissue surrounding it.
- Partial Gastrectomy: This type of surgery involves removing portions of the stomach. If the upper portion is removed, part of the esophagus may also be removed. If the lower portion is removed, sometimes the duodenum is also removed.
- Small Bowel (Small Intestine) Resection: This operation removes a piece of the small bowel (small intestine) and some of the surrounding tissue.
- Whipple Procedure: The Whipple Procedure is typically used to treat pancreatic cancer, but it is also used to treat cancers of the duodenum, surrounding lymph nodes, and the stomach. In this procedure, the gallbladder and a portion of the common bile duct are removed, and the remaining bile duct is attached to the small intestine, allowing bile produced by the liver to enter the small intestine directly.
- Medication: This includes somatostatin analogs, a synthetic version of somatostatin, a hormone that regulates a variety of bodily functions by hindering the release of hormones. Somatostatin analogs slow down the production of gut hormones and help control the symptoms of gastrointestinal carcinoid tumors.
- Targeted Therapy: These drugs that target specific pathways in cancer cells, inhibiting their growth. They are sometimes helpful when chemotherapy is not.
- Chemotherapy: While less common for carcinoid tumors due to their slow growth, chemotherapy might be used for aggressive or advanced cases.
- Radiation Therapy: This can be used to relieve symptoms, especially if the tumor is causing pain or has spread to the bones.
- Peptide Receptor Radionuclide Therapy (PRRT): This involves a drug that delivers a radioactive substance directly to the cancer cells. It is effective in some neuroendocrine tumors, including carcinoid tumors.
- Interventional Radiology Techniques: Techniques such as embolization or radiofrequency ablation can be used to reduce tumor size and manage symptoms, especially in tumors that have spread to the liver.
The choice of treatment often involves a multidisciplinary team of specialists, including oncologists, surgeons, radiologists, and gastroenterologists. The treatment plan often involves a combination of these methods and is personalized based on the patient's specific situation, including the cancer stage, location, and the patient's overall health. Regular follow-up and monitoring by your GW Cancer Center team are essential to assess the treatment's effectiveness and manage any side effects or complications.
