After making a diagnosis of cancer, clinicians have a number of treatment options. Most of these involve coordinating multiple attacks on the tumor using an arsenal of cancer-killing therapies. Chemotherapy, where toxic drugs are used to specifically kill cancer cells, is a very powerful weapon in this arsenal. It is extremely effective in treating some cancers, such as testicular cancer and Hodgkin's Disease, but works poorly in other cancer types. |

 Acute lymphoblastic leukemia (ALL) most commonly affects children, in whom there is an overall cure rate of 85%. A strong predictor of poor outcome is resistance to chemotherapy with glucocorticoids. Such resistance is caused, at least in part, by an inability of the leukemic cells to die by a process known as mitochondrial apoptosis. |
