: In recent years, numerous recurrently mutated genes have been identified in acute myeloid leukemia (AML), some of which, such as and , serve as therapeutic targets, offering new treatment options. Rapid mutational analysis is crucial for timely and optimal therapy selection. This study aims to develop and validate a rapid, cost-effective, and sensitive screening method for detecting , , and -TKD2 mutations using polymerase chain reaction (PCR) and high-resolution melting curve analysis (HRM). : A PCR-HRM assay was developed to simultaneously detect mutations in , , and -TKD2. The method was applied to a cohort of 1363 AML patients, and its performance, including turnaround time, was evaluated through comparison with next-generation sequencing (NGS) results. : The PCR-HRM method demonstrated a positive percent agreement of 98%, 98%, and 92% for , , and , respectively, and a negative percent agreement of 100% for all three genes compared to NGS. No false positives were observed, and false negatives were detected in less than 1% of cases, mostly in -TKD2, all occurring below the established limit of detection. The turnaround time and cost of PCR-HRM were significantly lower than those of NGS. : This method offers a highly sensitive, specific, and time-efficient approach for the simultaneous detection of , , and -TKD2 mutations in AML patients. Its rapid turnaround time and cost-effectiveness make it a valuable tool for routine clinical screening, facilitating timely and targeted treatment decisions.
近年来,急性髓系白血病(AML)中已鉴定出许多反复突变的基因,其中一些基因,如 和 ,可作为治疗靶点,提供了新的治疗选择。快速突变分析对于及时和优化治疗方案的选择至关重要。本研究旨在开发并验证一种快速、经济高效且灵敏的筛查方法,用于使用聚合酶链反应(PCR)和高分辨率熔解曲线分析(HRM)检测 、 和 -TKD2突变。
开发了一种PCR-HRM检测方法,用于同时检测 、 和 -TKD2中的突变。该方法应用于1363例AML患者队列,并通过与下一代测序(NGS)结果比较来评估其性能,包括周转时间。
与NGS相比,PCR-HRM方法对 、 和 的阳性百分比一致性分别为98%、98%和92%,对所有三个基因的阴性百分比一致性均为100%。未观察到假阳性,假阴性在不到1%的病例中被检测到,主要在 -TKD2中,所有假阴性均发生在既定检测限以下。PCR-HRM的周转时间和成本显著低于NGS。
该方法为同时检测AML患者中的 、 和 -TKD2突变提供了一种高度灵敏、特异且高效的方法。其快速的周转时间和成本效益使其成为常规临床筛查的有价值工具,有助于及时做出有针对性的治疗决策。
