Table 3 summarizes the correlation between the expression levels of FDX1 in ccRCC patients with various clinicopathological parameters. In addition, the expression level of FDX1 was different in groups classified based on the pathological grade, gender, TNM stage, T stage, lymph node metastasis, and distant metastasis (P < 0.05) (Figure 3). The gene discussed is FDX1; the disease is nonpapillary renal cell carcinoma.
