DAVID I. MARKS<br />

Chimeric antigen receptor T cells directed against CD19<br />

have shown remarkable effıcacy in a relatively small number<br />

of children but are likely to be tested in younger adults before<br />

any trials in the older-patient population. 24 A proportion of<br />

patients experience severe cytokine release syndrome requiring<br />

ICU admission; this could be a limiting factor in the older<br />

age group.<br />

CONCLUSION<br />

Effective management of older patients with ALL is a major<br />

unmet need. The different biology of the disease and the patient<br />

is recognized, and we now need the systematic trials that<br />

have improved the outcome of ALL in children and adults to<br />

be applied to the older age group. Many fıt patients between<br />

age 50 and 65 will be able to tolerate conventional aggressive<br />

chemotherapy with reasonable outcomes and acceptable<br />

NRM. However, older and less-fıt patients require lessaggressive<br />

chemotherapy, and strategies are needed to improve<br />

CR rates in this group. It is essential that we better<br />

understand the comorbidities that affect tolerance to chemotherapy<br />

so that we can rationally adjust therapy and not rely<br />

on end-of-the-bed impressions. Trials such as the United<br />

Kingdom ALL 60 study that assess comorbidities and include<br />

objective and subjective QOL endpoints will hopefully<br />

advance the fıeld. Leukemia physicians are urged to enter<br />

older patients into trials in order that we may improve the<br />

outcome of this diffıcult clinical management problem.<br />
