多发性骨髓瘤(MM)是一种恶性浆细胞在骨髓中单克隆增殖的血液肿瘤。Fascin(FSCN)是一种肌动蛋白结合蛋白,在细胞迁移和侵袭中起关键作用,有助于肿瘤转移。FSCN家族有三个成员(FSCN 1 -3)。然而,FSCN家族在MM中的预后作用仍不清楚。在这项研究中,我们使用了四个独立的基因表达综合数据集(GEO)来探索FSCN 1 -3表达谱与MM患者生存率之间的关系。我们发现,与正常供体(p < 0.001)和单克隆丙种球蛋白病(MGUS)(p = 0.032)相比,MM患者的FSCN 1显著下调。FSCN 1和FSCN 2高表达的患者OS显著延长(分别为p = 0.023和0.028)。单因素和多因素分析显示,FSCN 1(p = 0.003,0.002)和FSCN 2(p = 0.018,0.013)是MM患者OS的独立有利预后因素。此外,FSCN 1和FSCN 2高表达的组合可以有效预测更长的EFS(p = 0.046)和OS(p = 0.015)。我们的研究表明,FSCN 1和FSCN 2可以作为有利的生物标志物用于预测MM的临床结果。
Multiple myeloma (MM) is a hematologic tumor with monoclonal proliferation of malignant plasma cells in the bone marrow. Fascin (FSCN) is an actin-binding protein that plays a crucial role in cell migration and invasion, contributing to tumor metastasis. There are three members (FSCN1-3) in FSCN family. However, the prognostic role of FSCN family in MM remains unclear. In this study, we used four independent Gene Expression Omnibus (GEO) datasets to explore the relationships between FSCN1-3 expression profiles and patient survival in MM. We found that FSCN1 was dramatically down-regulated in MM compared to normal donors (p < 0.001) and monoclonal gammopathy of undetermined significance (MGUS) (p = 0.032). Patients with high expression of FSCN1 and FSCN2 had significantly longer OS (p = 0.023 and 0.028, respectively). Univariate and multivariate analysis showed that FSCN1 (p = 0.003, 0.002) and FSCN2 (p = 0.018, 0.013) were independent favorable prognostic factors for OS in MM. Moreover, the combination of high expression of FSCN1 and FSCN2 could effectively predict both longer EFS (p = 0.046) and OS (p = 0.015). Our study suggested that FSCN1 and FSCN2 can be used as favorable biomarkers for predicting clinical outcomes in MM.
