AR and nonpapillary renal cell carcinoma: The results from AR staining revealed that AR expression was higher in the ccRCC primary tumors (n = 39) compared to the adjacent tissues (n = 26) and was significantly lower in RBM tissues (n = 20) than those found in the primary tumor group (p < 0.001) using Image‐Pro Plus software (Figure 1D, Table S3).
