ABSTRACT
BACKGROUND:
Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Early diagnosis and timely treatment are essential for effective cancer control and have been widely analyzed in childhood cancer. However, few studies have described the time to diagnosis and treatment in children with ALL. This study investigated delays in diagnosis and treatment initiation and their impact on survival.METHODS:
This retrospective cohort study included 419 patients 0 to 14 years old at a tertiary hospital between 2011 and 2015. The optimal cutoff values for delays were determined by X-tile software. The Kaplan-Meier method and Cox regression models were used to evaluate the impact of delays on survival.RESULTS:
The median diagnosis, treatment, and total delays were 21 (interquartile range [IQR] 11-35), 4 (IQR 2-7), and 26 (IQR 16-43) days, respectively. The results of multivariate analyses showed that diagnosis delay, risk stratification, and minimal residual disease level were independent predictors for treatment outcome in childhood ALL.CONCLUSIONS:
These findings suggested that a longer time to diagnosis negatively affected the clinical outcome of childhood ALL. Reducing the time to diagnosis could help to improve survival in these patients.
