As shown in Figure 5, the expression levels of SLC22A6, SLC22A7, SLC22A13, SLC25A4, SLC34A1, and SLC44A4 in ccRCC were significantly correlated with the OS and DFS of patients, and the difference was statistically significant (P < 0.01). The gene discussed is SLC22A6; the disease is nonpapillary renal cell carcinoma.
