Non-Hodgkin's lymphoma(NHL) is a cancer that starts in cells called lymphocytes, which are part of the body's immune system. Lymphocytes are in the lymph nodes and other lymphoid tissues (such as the spleen and bone marrow). Non-hodgkin's lymphoma is classified with two broad categories, such as high-grade or aggressive and low-grade or indolent.

Response criteria for non-Hodgkin's lymphomas will be used to assess tumor response.
