Abstract Text While a substantial amount of data on gene mutations related to acute myeloid leukemia (AML) prognosis from western and other populations have been reported, these studies largely describe one or two genes. Additionally, in southwest China, only insufficient data exist regarding FLT3-ITD, FLT3-TKD, NPM1, C-KIT, DNMT3A, and CEBPA mutations have been widely used in clinical settings. Therefore, a comprehensive study about these mutations of clinical importance in the prognosis of AML in western China is necessary. In a cohort of 255 patients with de novo AML, we retrospectively analyzed the prevalence of the six gene mutations, and then we assessed the results in conjunction with clinical characteristics and treatment responses. As for the frequencies of these mutations, the NPM1 mutation occurred most frequently (17.7 %; 42/237), followed by the CEBPA mutation (15.0 %; 19/127) and the FLT3-ITD mutation (10.2 %; 25/244). The frequencies of the FLT3-TKD, DNMT3A, and C-KIT mutations were 3.7 % (9/234), 4.0 % (9/225) and 4.2 % (10/238), respectively. These mutations were closely related to clinical characteristics including FAB classification, gender and age, hemogram, blasts (%), fusion genes, and immunophenotypes. Additionally, a higher complete remission (CR) rate was found in NPM1-mutated patients. The occurrence of these mutations is variable among different countries and regions worldwide, which may provide clues to the etiology of AML. Besides, we identified new clinical characteristics that advance our understanding of these mutations and further clarify the involvement of these mutations in the development of leukemia.

Filtering

  • 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"

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.
