In addition, high expressions of C1R (HR = 2.300, P = 7.9E-06, Figure 6A), C1S (HR = 2.300, P = 6E-06, Figure 6B), CP (HR = 1.500, P = 0.037, Figure 6F), MMP7 (HR = 1.700, P = 0.003, Figure 6L), PRIMA1 (HR = 1.600, P = 0.007, Figure 6M), SERPINF1 (HR = 1.800, P = 0.002, Figure 6N), SLC38A5 (HR = 1.800, P = 0.002, Figure 6O), and TGFBI (HR = 1.800, P = 0.001, Figure 6P) were significantly correlated with DFS of ccRCC patients. The gene discussed is C1R; the disease is nonpapillary renal cell carcinoma.
