Conventional PCR Versus Next Generation Sequencing for Diagnosis of FLT3, IDH and NPM1 Mutations in Acute Myeloid Leukemia: Results of the PETHEMA PCR-LMA Study.
Article in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND/
objectivesThis PETHEMA PCR-LMA study aimed to evaluate whether mutations detected by NGS (VAF cut-off of ≥5%) correlate with NPM1, FLT3-ITD, FLT3-TKD, IDH1, and IDH2 mutations detected using conventional PCR (analytical sensitivity 3%) in a nationwide network of seven reference laboratories.
methodsBetween 2019 and 2021, 1685 adult AML patients with at least one centralized sample (NGS or PCR) at primary diagnosis or relapse/refractory episode were included.
resultsDuring this period, 1288 paired NGS/PCR samples (1094 at diagnosis, 103 at relapse and 88 at refractoriness) were analyzed. Considering PCR the gold-standard, for NPM1 NGS sensitivity was 98.5% and specificity 98.9%, for FLT3-ITD 73.8% and 99.6%, for FLT3-TKD 84.5% and 99.3%, for IDH1 98.7% and 98.7%, and for IDH2 99.1% and 97.7%, respectively. Overall concordance rate of positive results between NGS (and PCR was 95% (262/276) for NPM1, 72% (149/206) for FLT3-ITD, 74% (49/66) for FLT3-TKD, 87% (77/89) for IDH1 and 84% (107/127) for IDH2. Overall, median days from sample reception until report were 7 for PCR and 28 for NGS.
conclusionsThis study shows high concordance between NPM1 and IDH results using PCR and NGS. However, sensible important discrepancies are observed for FLT3 mutations. In our context, rapid screening for these druggable mutations should be performed by conventional PCR.
