On this basis, we finally identified five pairs of microbe–gene association and one pair of microbe–cell with significance, including the genus Planococcus, Xanthobacter, and Blastcoccus; the genes GGCT, LOC102723808, EGFEM1P, PTGER1, and MFAP2; and the cell type myeloid dendritic cell activated, which were all involved in the tumorigenesis and tumor progression via inflammation-related pathways. Here, MFAP2 is linked to neoplasm.
