Abstract
Recently, emerging evidence suggests an association between MECOM (MDS1 and EVI1 complex locus) and cancers. However, a comprehensive pan-cancer analysis to fully investigate this relationship is lacking. Herein, public platforms with large-scale genomics, including The Cancer Genome Atlas, Gene Expression Omnibus dataset, and the Human Protein Atlas were explored to investigate the prognostic and immunological roles of MECOM across certain cancer types. Our findings revealed differential expression of MECOM in various cancer types, indicating its potential to predict diverse clinical outcomes, such as overall survival time and disease-free survival time in patients with various malignancies. Additionally, we observed an association between the mutation burden in MECOM in various cancers and patient survival. Furthermore, the mechanism of MECOM-mediated oncogenesis was tentatively explored by immune infiltration analysis. This study provided a relatively comprehensive overview of the prognostic and immunological roles of MECOM in multiple cancers.
