Mutation of FLT3 gene in acute myeloid leukemia with normal cytogenetics and its association with clinical and immunophenotypic features.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Acute myeloid leukemia (AML) with normal karyotype represents a clinically and molecularly heterogeneous disease. Molecular markers with prognostic significance have been examined to improve risk profile characterization of this group. Activating mutations on FLT3 receptor are one of the most common genetic alterations reported. However, the prevalence and prognostic significance of FLT3 genetic alterations in AML patients with cytogenetically normal karyotype is still controversial. In this study, FLT3/ITD and FLT3/D835 mutations were analyzed in 133 patients with de novo AML with normal cytogenetics by genomic PCR assay. Of 133 patients with AML with normal cytogenetics, FLT3 internal tandem duplication (ITD) and FLT3/D835 mutations were detected in 27 (20%) and 4 (3%) samples, respectively. Although statistically insignificant, the frequency of FLT3/ITD was higher in >15 year age group when compared to <15 year group (23 vs. 13%, P = 0.2). The white blood count was found to be significantly higher in patients with FLT3/ITD mutation when compared to those without the mutation (40 × 10⁹/L vs. 20 × 10⁹/L, P = < 0.002) or those with FLT3/D835 mutations (30 × 10⁹/l). Aberrant expression of CD7 was observed more frequently in patients with FLT3/ITD mutation (P < 0.002). There was no significant difference in the response rate to chemotherapy in patients with or without FLT3/ITD mutation (67 and 64%, respectively). FLT3/ITD mutation was found to be associated with the age, leukocytosis and aberrant expression of CD7, although no influence of FLT3/ITD mutation was seen on the clinical outcome of AML patients with normal cytogenetics.
