Epithelial growth factor-like 7 (EGFL7) is a secretory protein with a well-characterized role in angiogenesis and the oncogenesis of certain solid tumors. Overexpression of is associated with adverse prognosis in patients with cytogenetically normal acute myeloid leukemia (CN-AML). However, whether this association persists after allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains unclear. To further clarify the prognostic role of , seventy-one AML patients with expression data who underwent allo-HSCT from The Cancer Genome Atlas database were included and divided into either or group based on the median expression level. Two groups had similar clinical and molecular characteristics except that the group had less frequent mutations (= .001). Kaplan-Meier survival curves showed that high expressers had shorter OS than the low expressers (= .040). Univariate analysis showed that high expression, and mutations were associated with short OS (all < .05). Multivariate analysis indicated that high expression, and mutations were independent risk factors for OS (all < .05). Collectively, our study suggested that , like the other widely-used risk stratification factors, could serve as a prognostic tool and therapeutic target in AML, even after allo-HCST.
表皮生长因子样蛋白 7(EGFL7)是一种分泌蛋白,其在血管生成和某些实体瘤的发生中具有明确的作用。 过表达与核型正常的急性髓细胞白血病(CN-AML)患者的不良预后相关。 但是,异体造血干细胞移植(allo-HSCT)后这种相关性是否仍然存在尚不清楚。 为了进一步阐明 的预后作用,从 The Cancer Genome Atlas 数据库中纳入了 71 例接受 allo-HSCT 的 AML 患者,这些患者具有 表达数据,并根据 的中位表达水平将其分为 或 组。 两组具有相似的临床和分子特征,除了 组中 突变的频率较低(= 0.001)。Kaplan-Meier 生存曲线表明,高 表达者的 OS 短于低表达者(= 0.040)。单因素分析表明,高 表达、 和 突变与 OS 短有关(均 < 0.05)。多因素分析表明,高 表达、 和 突变是 OS 的独立危险因素(均 < 0.05)。综上所述,我们的研究表明, 与其他广泛使用的风险分层因素一样,即使在 allo-HCST 后,也可以作为 AML 的预后工具和治疗靶标。
