What does this research mean for the field?

In pediatric B-cell acute lymphoblastic leukemia patients in resource-limited settings, socioeconomic vulnerabilities—particularly indigenous status and treatment non-adherence—independently drive relapse and significantly reduce overall survival. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate clinical outcomes in pediatric B-cell acute lymphoblastic leukemia and determine how socioeconomic vulnerabilities, including indigenous status and treatment non-adherence, influence relapse and survival in a resource-limited setting.

Retrospective cohort study reveals poor survival and high relapse rates in pediatric leukemia, highlighting the severe impact of socioeconomic vulnerabilities and treatment non-adherence.

Key Points

To evaluate clinical outcomes in pediatric B-cell acute lymphoblastic leukemia and determine how socioeconomic vulnerabilities, including indigenous status and treatment non-adherence, influence relapse and survival in a resource-limited setting.
Retrospective cohort study of 146 pediatric patients (aged 0–17 years) treated between 2010 and 2024 in Southern Mexico using modified Total XIII and XV protocols.
Survival outcomes were evaluated using Kaplan–Meier estimates, and independent prognostic factors for relapse and overall survival were determined via multivariable Cox proportional hazards models.
The 5-year overall survival (OS) was 50.0% and event-free survival was 37.6%, with OS varying markedly across low-risk (88%), standard-risk (77%), and high-risk (31%) categories.
Documented treatment non-adherence significantly worsened 5-year OS (23.4% vs. 56.1%, p = 0.001) and disproportionately affected indigenous patients compared to non-indigenous patients (55.5% vs. 10.1%).
Overall relapse reached 45.8%, with multivariable analysis identifying indigenous status as an independent predictor of increased relapse risk (HR = 1.89, p = 0.049), along with male sex and elevated leukocyte counts.
