                    There are different types of treatment for patients with metastatic squamous neck cancer with occult primary.
                    Different types of treatment are available for patients with metastatic squamous neck cancer with occult primary. 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.
                
                
                    Two types of standard treatment are used:
                    Surgery      Surgery may include neck dissection. There are different types of neck dissection, based on the amount of tissue that is removed.             - Radical neck dissection: Surgery to remove tissues in one or both sides of the neck between the jawbone and the collarbone, including the following:                  - All lymph nodes.       - The jugular vein.       - Muscles and nerves that are used for face, neck, and shoulder movement, speech, and swallowing.            The patient may need physical therapy of the throat, neck, shoulder, and/or arm after radical neck dissection. Radical neck dissection may be used when cancer has spread widely in the neck.      - Modified radical neck dissection: Surgery to remove all the lymph nodes in one or both sides of the neck without removing the neck muscles. The nerves and/or the jugular vein may be removed.      - Partial neck dissection: Surgery to remove some of the lymph nodes in the neck. This is also called selective neck dissection.            Even if the doctor removes all the cancer that can be seen at the time of surgery, some patients may be given radiation therapy after surgery to kill any cancer cells that are left. Treatment given after surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.       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. This type of radiation therapy may 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. This type of radiation therapy is less likely to cause dry mouth, trouble swallowing, and damage to the skin.                -  Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.           The way the radiation therapy is given depends on the type of cancer being treated. External radiation therapy is used to treat metastatic squamous neck cancer with occult primary.    Radiation therapy to the neck may change the way the thyroid gland works. Blood tests may be done to check the thyroid hormone level in the body before treatment and at regular checkups after treatment.
                
                
                    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.     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).        Hyperfractionated radiation therapy     Hyperfractionated radiation therapy is a type of external radiation treatment in which a smaller than usual total daily dose of radiation is divided into two doses and the treatments are given twice a day. Hyperfractionated radiation therapy is given over the same period of time (days or weeks) as standard radiation therapy.
                
                
                    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.
