Different types of treatment are available for patients with nasopharyngeal 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.
Note: Separate PDQ summaries on Testicular Cancer Treatment and Levels of Evidence for Cancer Screening and Prevention Studies are also available.
Based on fair evidence, screening for testicular cancer would not result in an appreciable decrease in mortality, in part because therapy at each stage is so effective.
Magnitude of Effect: Fair evidence of no reduction in mortality.
Study Design: Opinions of respected authorities based on clinical experience, descriptive...
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. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
External radiation therapy to the thyroid or the pituitary gland may change the way the thyroid gland works. The doctor may test the thyroid gland before and after therapy to make sure it is working properly. It is also important that a dentist check the patient's teeth, gums, and mouth, and fix any existing problems before radiation therapy begins.
Intensity-modulated radiation therapy (IMRT) is a type of 3-dimensional 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 causes less damage to healthy tissue near the tumor. Compared to standard radiation therapy, intensity-modulated radiation therapy may be less likely to cause xerostomia (dry mouth). This may improve the patient's quality of life.
