III study compares four chemotherapy treatments for children with newly diagnosed disseminated and localized lymphoblastic lymphoma.
Lymphoma is a cancer of the lymph system.
The lymph system is made up of the lymph nodes and other lymph tissue throughout the body, which make and store infection fighting white blood cells called lymphocytes. These cells become cancerous when a patient has lymphoma. If the cancer is only located in one region of the body and that region is not one mentioned above, the lymphoma is considered localized. Localized lymphoblastic lymphoma is rare. The primary goal of this study is to compare four treatment arms for lymphoblastic lymphoma to find out which treatment arm results in a better rate of cancer-free survival.
