High-dose Chemotherapy

High-dose chemotherapy (HDCT) is the use of high doses of chemotherapy drugs for the treatment of cancer. The aim of this therapy is to destroy cancer cells that may have spread throughout the body more effectively than standard lower doses. HDCT is often used in combination with bone marrow transplantation in order to prevent relapse when other treatments are not successful. Although this type of therapy is associated with more serious side effects than other treatments, it is increasingly being used to effectively treat some cancers when other treatments are no longer effective.
