The RF classifier algorithm obtained the specific importance ranking of prognostic genes in terms of tumor metastasis correlation (Figure 5E) and finally screened the seven prognostic genes with the highest correlation with tumor metastasis (INSR, FAM162A, GLCE, ADH5, G6PD, SDC3, HS2ST1), and constructed metastasis-related disease models based on the seven genes (Figure 5F). Here, FAM162A is linked to neoplasm.
