Acute lymphoblastic leukemia in young adults:  which treatment?
OBJECTIVE
Acute lymphoblastic leukemia (ALL) is the most common and one of the most curable malignancies in children; however, it presents unique challenges in adolescents and young adults (AYAs). The purpose of this review is to discuss factors that contribute to the outcome disparities in AYAs with ALL as well as approaches that can be taken to optimize the care of this patient population.


RESULTS
AYAs with ALL are unique and have outcomes that have lagged behind those observed in children with ALL. Contributing factors to the challenges faced by this group include distinctive disease biology, different drug pharmacology and toxicity profiles, and complex psychosocial and socioeconomic factors. Several clinical trials conducted worldwide have demonstrated that treatment with pediatric protocols significantly improves outcomes in the AYA population.


CONCLUSIONS
Initiatives to improve outcomes for AYAs with ALL include treatment with pediatric regimens tailored to be delivered without excessive toxicity and in centers with the necessary supportive care and medical services to address the specific needs of this population. As more is understood about the unique disease biology of AYA ALL, targeted therapeutic approaches may offer promise for the future.
