The identified Gram-negative bacteria, including <em>Escherichia coli</em> (<em>E. coli</em>), <em>Prevotella bivia</em> (<em>P. bivia</em>), and <em>Fusobacterium nucleatum</em> (<em>F. nucleatum</em>), were isolated, and their roles in metastasis were examined using <em>in vitro</em> transwell and capillary tube formation assays on human lymphatic endothelial cells (HLEC).
