SAA1 and nonpapillary renal cell carcinoma: Our results indicated that high SAA1 expression could serve as a potential prognostic factor for ccRCC patients with T1 + T2 stage (Figure 7A, p = 0.0002), T3 + T4 stage (Figure 7B, p = 0.0030), N0 stage (Figure 7C, p < 0.0001), M0 stage (Figure 7D, p < 0.0001), G1 + G2 stage (Figure 7E, p = 0.0088), G3 + G4 stage (Figure 7F, p = 0.0014), Stage I+II (Figure 7G, p = 0.0004), Stage III+IV (Figure 7H, p = 0.0081), Female (Figure 7I, p < 0.0001), Male (Figure 7J, p = 0.0009), Age ≥ 60 years (Figure 7K, p < 0.0001), Age < 60 years (Figure 7L, p = 0.0044).
