October 26th 2015Acute lymphoblastic leukemia (ALL) is a relatively rare malignancy in adults, with an estimated 6250 new cases and 1450 deaths expected in the United States in 2015. Although most patients achieve complete remission with conventional combination chemotherapy regimens, at least two-thirds of high-risk patients relapse.2 While overall survival for children has significantly improved in the last 30 years, newly diagnosed adults continue to have a poor 5-year OS rate, approximating 35%, depending on age and risk factors.
