Five-Year Survival About 40 to 50 percent, although the prognosis for patients varies depending on the prognostic factors listed in "Treatment Overview by Grade."
Investigational Because patients with multiple risk factors have a poor prognosis, participation in an investigational program should be considered. Most investigational efforts have the goal of increasing the intensity of treatment by using hematopoietic growth factors or bone marrow transplantation. Modulation of multi-drug resistance is also under investigation.
