Treatment trials

Most cancer clinical trials are treatment studies that involve people who have cancer. These studies test new treatments or new ways of using existing treatments, such as medicines, vaccines, ways of doing surgery or methods for doing radiation therapy, or combinations of treatments.

There is another type of treatment trial that involves testing cancer cells for the presence of specific molecular markers. These markers can include changes in certain genes or proteins. These changes may help us to further classify cancers. This can help researchers find better treatments for these specific cancers.

Treatment trials are designed to answers questions such as:

  • What new treatment methods can help people who have cancer?
  • What is the most effective treatment for people who have cancer?
  • Does the new treatment work as well as the old treatment?
  • What are the new treatment’s side effects?
