Although acute myeloid leukemia (AML) with -ITD is a low-risk entity, its relapse rate remains high. Out of 333 AML patients, 27 were , and were analyzed in greater detail in order to find associations between clinical and molecular features and cumulative incidence of relapse. Next-generation sequencing (NGS) was performed on diagnosis and remission samples using two capture-based panels. The presence of the variant at diagnosis and a qPCR value of ≥0.1% after induction chemotherapy were associated with an increased probability of relapse, especially if both conditions are present together. By contrast, patients in which the main clone found at diagnosis harbored variant had a lower risk of relapse. Nineteen of the 85 variants found at diagnosis were detected by NGS in remission. AML Subgroup with /-ITD is a heterogeneous entity, which can be further risk-stratified based on molecular biomarkers.
尽管伴有-ITD 的急性髓系白血病 (AML) 属于低危实体,但它的复发率仍然很高。在 333 名 AML 患者中,有 27 名患者存在这种情况,我们对其进行了更详细的分析,以寻找临床和分子特征与复发累积发生率之间的关联。使用两个基于捕获的试剂盒在诊断和缓解样本上进行了下一代测序 (NGS)。诊断时存在 变体和诱导化疗后 qPCR 值≥0.1%与复发概率增加相关,尤其是如果两种情况同时存在。相比之下,在诊断时发现主要克隆携带 变体的患者复发风险较低。在诊断时发现的 85 种变体中有 19 种在缓解时通过 NGS 检测到。AML 伴 /-ITD 亚组是一个异质性实体,可以根据分子生物标志物进一步进行风险分层。
