Introduction: Acute lymphocytic leukemia is a neoplasm, affects mostly children, its overall survival is low in emerging countries. Immunophenotype, prognostic factor to OS percentage. There is no update on OS, genetic and phenotypic abnormalities associated with ALL. Objective: To estimate association between immunophenotypic and cytogenetic-molecular factors at 3-year OS in children with ALL from INSN SB between 2016-2020. Methods: Analytical observational retrospective cohort study based on electronic medical records. 202 records of patients aged 1-18 years with ALL. The outcome variable was OS and exposure, immunophenotype and cytogenetic-molecular variables. Absolute and relative frequencies were used for descriptive analysis, Chi2 and fisher exact test for bivariate, Kaplan-Meier curves were compared with log-rank test. Multivariate, crude hazard ratio and adjusted by Cox regression models with 95% CI. Results: 61.4% were male, 95% B lineage, 43% diploidy, 22% hyperdiploidy, 55% died. Patients who died had elevated white blood cell count, median p25-p75: 5.4- 77.6. T lineage presented 1.78 hazard of death at 3 years and long range test as a function of survival <0.05. Hypodiploidy, Philadelphia chromosome, complex chromosomes, deletions and diploidy 1.07 hazard of death at 3 years and long range test 0.549, not statistically significant. The scenarios have p <0.05 and 95% CI. Conclusion: There is an association between survival and immunophenotype. Type T reflects lower probability of survival. There was no association between cytogenetic-molecular factors and survival. Overall survival was 44.6% between 2016-2020.
