                    There are different types of treatment for patients with bile duct cancer.
                    Different types of treatments are available for patients with bile duct cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
                
                
                    Three types of standard treatment are used:
                    Surgery    The following types of surgery are used to treat bile duct cancer:            - Removal of the bile duct: A surgical procedure to remove part of the bile duct if the tumor is small and in the bile duct only. Lymph nodes are removed and tissue from the lymph nodes is viewed under a microscope to see if there is cancer.      -  Partial hepatectomy: A surgical procedure in which the part of the liver where cancer is found is removed. The part removed may be a wedge of tissue, an entire lobe, or a larger part of the liver, along with some normal tissue around it.      -  Whipple procedure: A surgical procedure in which the head of the pancreas, the gallbladder, part of the stomach, part of the small intestine, and the bile duct are removed. Enough of the pancreas is left to make digestive juices and insulin.           Even if the doctor removes all the cancer that can be seen at the time of the operation, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. It is not yet known whether chemotherapy or radiation therapy given after surgery helps keep the cancer from coming back.    The following types of palliative surgery may be done to relieve symptoms caused by a blocked bile duct and improve quality of life:            -  Biliary bypass: A surgical procedure in which the part of the bile duct before the blockage is connected with part of the bile duct that is past the blockage or to the small intestine. This allows bile to flow to the gallbladder or small intestine.     -  Stent placement: A surgical procedure in which a stent (a thin, flexible tube or metal tube) is placed in the bile duct to open it and allow bile to flow into the small intestine or through a catheter that goes to a collection bag outside of the body.      -  Percutaneous transhepatic biliary drainage: A procedure used to x-ray the liver and bile ducts. A thin needle is inserted through the skin below the ribs and into the liver. Dye is injected into the liver or bile ducts and an x-ray is taken. If the bile duct is blocked, a thin, flexible tube called a stent may be left in the liver to drain bile into the small intestine or a collection bag outside the body.              Radiation therapy     Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:             -  External radiation therapy uses a machine outside the body to send radiation toward the cancer.     -   Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.           External and internal radiation therapy are used to treat bile duct cancer.    It is not yet known whether external radiation therapy helps in the treatment of resectable bile duct cancer. In unresectable, metastatic, or recurrent bile duct cancer, new ways to improve the effect of external radiation therapy on cancer cells are being studied:            -  Hyperthermia therapy: A treatment in which body tissue is exposed to high temperatures to make cancer cells more sensitive to the effects of radiation therapy and certain anticancer drugs.     -  Radiosensitizers: Drugs that make cancer cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more cancer cells.              Chemotherapy     Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy).     Systemic chemotherapy is used to treat unresectable, metastatic, or recurrent bile duct cancer. It is not yet known whether systemic chemotherapy helps in the treatment of resectable bile duct cancer.     In unresectable, metastatic, or recurrent bile duct cancer, intra-arterial embolization is being studied. It is a procedure in which the blood supply to a tumor is blocked after anticancer drugs are given in blood vessels near the tumor. Sometimes, the anticancer drugs are attached to small beads that are injected into an artery that feeds the tumor. The beads block blood flow to the tumor as they release the drug. This allows a higher amount of drug to reach the tumor for a longer period of time, which may kill more cancer cells.
                 
                
                    New types of treatment are being tested in clinical trials.
                    This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.     Liver transplant    In a liver transplant, the entire liver is removed and replaced with a healthy donated liver. A liver transplant may be done in patients with perihilar bile duct cancer. If the patient has to wait for a donated liver, other treatment is given as needed.
                
                
                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
                
                
                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
                
                
                    Follow-up tests may be needed.
                    Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.   Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
