Types of Clinical Trials
- Prevention trials study ways to reduce the risk, or chance, of developing cancer. Most prevention trials are conducted with healthy people who have not had cancer. Some trials are conducted with people who have had cancer and want to prevent the return or recurrence of the cancer. Prevention trials look at the kinds of interventions, such as lifestyle modifications, dietary supplement or drugs that can prevent cancer from occurring.
- Screening trials study ways to detect cancer. They are often conducted to determine whether finding cancer before it causes symptoms decreases the chance of dying from the disease. These trials involve people who do not have any symptoms of cancer.
- Diagnostic trials study tests or procedures that could be used to identify cancer more accurately and at an earlier stage. Diagnostic trials usually include people who have signs or symptoms of cancer.
- Treatment trials are conducted with people who have cancer. They are designed to answer specific questions about, and evaluate the effectiveness of new treatments or a new ways of using a standard treatments. These trials test many types of treatments, such as new drugs, vaccines, new approaches to radiation therapy or new combinations of treatments.
- Supportive care trials explore ways to improve the comfort and quality of life of cancer patients and cancer survivors.
