The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in <a href="https://www.cancer.gov/espanol/publicaciones/pdq" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">Spanish</a>.</p><p id="CDR0000258022__AboutThis_4">PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government&#x02019;s center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.</p></div><div id="CDR0000258022__AboutThis_5"><h3>Purpose of This Summary</h3><p id="CDR0000258022__AboutThis_6">This PDQ cancer information summary has current information about the treatment of mycosis fungoides (including S&#x000e9;zary Syndrome). It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.</p></div><div id="CDR0000258022__AboutThis_7"><h3>Reviewers and Updates</h3><p id="CDR0000258022__AboutThis_8">Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change.
</p><p id="CDR0000258022__AboutThis_9">The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the <a href="https://www.cancer.gov/publications/pdq/editorial-boards/adult-treatment" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">PDQ Adult Treatment Editorial Board</a>.
</p></div><div id="CDR0000258022__AboutThis_10"><h3>Clinical Trial Information</h3><p id="CDR0000258022__AboutThis_11">A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." 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.
