is involved in leukemogenesis via mediating multiple pathways. The current study aimed to further explore its clinical roles in disease risk, clinical features, and prognosis in patients with acute myeloid leukemia (AML).
A total of 161 adult AML patients, 50 patients as a disease control (DC) group, and 50 healthy individuals as a healthy control (HC) group were enrolled and bone marrow mononuclear cells were collected. Subsequently, reverse transcriptionquantitative polymerase chain reaction (RT-qPCR) was performed to measure expression.
expression was higher in AML patients than in the DC and HC groups (both p<0.001), with good value in distinguishing AML patients from DC and HC individuals (area under the curve of 0.726 and 0.884, respectively). Moreover, expression was positively associated with white blood cell (WBC) count (p=0.008) but was not correlated with other clinical features such as cytogenetics, molecular genetics, and risk stratification (all p>0.05). expression was also associated with a lower complete remission (CR) rate (p=0.001). Patients with expression in the fourth quantile had the worst CR rates compared to patients with expressions in the first, second, and third quantiles (all p<0.05). Furthermore, expression was correlated with unsatisfactory event-free survival (p<0.001) and overall survival (p=0.002), which were worst in patients with expression in the fourth quantile compared to patients with expressions in the first, second, and third quantiles (all p<0.05).
overexpression is associated with elevated WBC count, poor induction treatment response, and poor survival profile in cases of AML and it may serve as a potential indicator for AML.
通过介导多种途径参与白血病的发生。本研究旨在进一步探讨其在急性髓系白血病(AML)患者疾病风险、临床特征和预后中的临床作用。
共纳入 161 例成人 AML 患者,其中 50 例为疾病对照组(DC),50 例健康个体为健康对照组(HC),采集骨髓单个核细胞。随后,采用逆转录定量聚合酶链反应(RT-qPCR)检测表达。
AML 患者中表达高于 DC 和 HC 组(均 p<0.001),在区分 AML 患者与 DC 和 HC 个体方面具有良好的价值(曲线下面积分别为 0.726 和 0.884)。此外,表达与白细胞计数(WBC)呈正相关(p=0.008),但与其他临床特征如细胞遗传学、分子遗传学和风险分层无关(均 p>0.05)。表达也与较低的完全缓解(CR)率相关(p=0.001)。第四四分位数表达的患者 CR 率最差,与第一、二、三分位表达的患者相比(均 p<0.05)。此外,表达与不良无事件生存(p<0.001)和总生存(p=0.002)相关,第四四分位数表达的患者最差,与第一、二、三分位表达的患者相比(均 p<0.05)。
过表达与 AML 患者白细胞计数升高、诱导治疗反应不良和生存不良相关,可能成为 AML 的潜在指标。
