Abstract

In order to establish the cutoff with prognostic implications for white blood cell count and age at diagnosis in adults with acute lymphoblastic leukemia (ALL), we conducted an observational, descriptive and analytical study nested in a retrospective cohort of patients with ALL treated by institutional protocol HGMLAL07 during 2007-2014. We study 255 patients, the 52.9% (n=135) were female and 47.1% (n=120) were male. The mean age was 31 (16-80) years-old. The disease-free survival (DFS) decreases in both genders after 20 years-old (p = 0.001). Leukocyte count average was 56.1 x 109/L (0.1-850 x 109/L). DFS decreases significantly from an equal or greater leukocyte count of 20 x 109/L (p<0.05). With this results, we can conclude that use foreign cutoff for age and leukocyte count could determine a bad prognosis stratification and a consequent suboptimal treatment.
