The resulting Kaplan–Meier plot showed that ccRCC patients with high SPOCK1 expression had poor overall survival (OS) (p = 0.002), disease-specific survival (DSS) (p < 0.001), and disease-free survival (DFS) (p = 0.019) (Figure 1C, left panel). Here, SPOCK1 is linked to nonpapillary renal cell carcinoma.
