                    There are different types of treatment for patients with oropharyngeal cancer.
                    Different types of treatment are available for patients with oropharyngeal 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.
                
                
                    Patients with oropharyngeal cancer should have their treatment planned by a team of doctors with expertise in treating head and neck cancer.
                    The patient's treatment will be overseen by a medical oncologist, a doctor who specializes in treating people with cancer. Because the oropharynx helps in breathing, eating, and talking, patients may need special help adjusting to the side effects of the cancer and its treatment. The medical oncologist may refer the patient to other health professionals with special training in the treatment of patients with head and neck cancer. These may include the following specialists:         - Head and neck surgeon.    -  Radiation oncologist.    -  Plastic surgeon.    -  Dentist.    -  Dietitian.    -  Psychologist.    -  Rehabilitation specialist.    -  Speech therapist.
                
                
                    Four types of standard treatment are used:
                    Surgery      Surgery (removing the cancer in an operation) is a common treatment of all stages of oropharyngeal cancer. A surgeon may remove the cancer and some of the healthy tissue around the cancer. Even if the surgeon removes all the cancer that can be seen at the time of the surgery, 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.    New types of surgery, including transoral robotic surgery, are being studied for the treatment of oropharyngeal cancer. Transoral robotic surgery may be used to remove cancer from hard-to-reach areas of the mouth and throat. Cameras attached to a robot give a 3-dimensional (3D) image that a surgeon can see. Using a computer, the surgeon guides very small tools at the ends of the robot arms to remove the cancer. This procedure may also be done using an endoscope.       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. Certain ways of giving radiation therapy can help keep radiation from damaging nearby healthy tissue. These types of radiation therapy include the following:                  -   Intensity-modulated radiation therapy (IMRT): IMRT is a type of 3-dimensional (3-D) radiation therapy that uses a computer to make pictures of the size and shape of the tumor. Thin beams of radiation of different intensities (strengths) are aimed at the tumor from many angles.       -  Stereotactic body radiation therapy: Stereotactic body radiation therapy is a type of external radiation therapy. Special equipment is used to place the patient in the same position for each radiation treatment. Once a day for several days, a radiation machine aims a larger than usual dose of radiation directly at the tumor. By having the patient in the same position for each treatment, there is less damage to nearby healthy tissue. This procedure is also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.                -  Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.           In advanced oropharyngeal cancer, dividing the daily dose of radiation into smaller-dose treatments improves the way the tumor responds to treatment. This is called hyperfractionated radiation therapy.    The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat oropharyngeal cancer.    Radiation therapy may work better in patients who have stopped smoking before beginning treatment.     If the thyroid or pituitary gland are part of the radiation treatment area, the patient has an increased risk of hypothyroidism (too little thyroid hormone). A blood test to check the thyroid hormone level in the body should be done before and after treatment.       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).     The way the chemotherapy is given depends on the type and stage of the cancer being treated. Systemic chemotherapy is used to treat oropharyngeal cancer.    See Drugs Approved for Head and Neck Cancer for more information. (Oropharyngeal cancer is a type of head and neck cancer.)       Targeted therapy     Targeted therapy is a type of treatment that uses drugs or other substances to attack specific cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy or radiation therapy do. Monoclonal antibodies are a type of targeted therapy being used in the treatment of oropharyngeal cancer.    Monoclonal antibody therapy is a cancer treatment that uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances in the blood or tissues that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells.     Cetuximab is a type of monoclonal antibody that works by binding to a protein on the surface of the cancer cells and stops the cells from growing and dividing. It is used in the treatment of recurrent oropharyngeal cancer.    Other types of monoclonal antibody therapy are being studied in the treatment of oropharyngeal cancer. Nivolumab is being studied in the treatment of stage III and IV oropharyngeal cancer.    See Drugs Approved for Head and Neck Cancer for more information. (Oropharyngeal cancer is a type of head and neck cancer.)
                
                
                    New types of treatment are being tested in clinical trials.
                    Information about clinical trials is available from the NCI website.
                
                
                    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.   Following treatment, it is important to have careful head and neck exams to look for signs that the cancer has come back. Check-ups will be done every 6 to 12 weeks in the first year, every 3 months in the second year, every 3 to 4 months in the third year, and every 6 months thereafter.
