Title The impact of IKZF1 deletion on the prognosis of acute lymphoblastic leukemia: an updated meta-analysis.

Abstract Text Various studies have reported that IKZF1 deletion (IKZF1-d) is a poor prognostic factor for acute lymphoblastic leukemia (ALL) patients, however they do not agree on the level of significance for this deletion.To provide a quantitative assessment of this correlation, an updated meta-analysis of cohort studies was performed to derive a more precise estimation of the prognostic significance of IKZF1-d.Relevant studies were identified in PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang databases until January 31, 2014. A total of 15 published studies including 5021 patients were eligible for this meta-analysis. Combined hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated with random-effects model.Combined hazard ratios suggested that IKZF1 deletion (IKZF1-d) had an unfavorable impact on event-free survival (EFS) (HR=2.32, 95%CI: 1.97-2.74) and overall survival (OS) (HR=2.56, 95%CI: 1.75-3.74) in patients with ALL. The significant role of IKZF1-d in the prognosis of ALL was also observed among different subgroups stratified by statistical methodology, ethnicity, age, detection method, risk group and duration of follow up.The findings from this meta-analysis suggest that IKZF1 deletion can be used to serve as an independent predictive factor in patients with ALL.


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"


  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.
