Abstract Text Isocitrate dehydrogenase 1 (IDH1) gene aberrations have recently been reported in acute myeloid leukemia (AML). To evaluate the prognostic significance of IDH1 mutations in AML, we performed a meta-analysis. Fifteen studies covering a total of 8121 subjects were included in this analysis. The frequency of IDH1 R132 mutations were 4.4-9.3% for AML patients and 10.9-16.0% for cytogenetically normal (CN)-AML patients. The IDH1 mutations were associated with NPM1 mutations in 6 studies and normal cytogenetics in 5 studies. AML patients with IDH1 mutations had inferior overall survival compared to patients without the mutations (hazard ratio 1.17, 95% CI: 1.02-1.36). Additionally, in CN-AML patients, IDH1 mutations were associated with a lower complete remission rate (risk ratio 1.30, 95% CI: 1.04-1.63). Although the available literature is limited to observational studies, these results may justify the risk-adapted therapeutic strategies for AML according to the IDH1 status.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • 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.
