The results of immunohistochemical staining analysis also demonstrated that 24 (96%) of 25 ccRCC tissues showed the positive staining for MYC, including 15 cases with 3+ staining, 7 cases with 2+ staining, and 2 cases with 1+ staining, but negative staining for nonneoplastic renal tubules. Here, MYC is linked to nonpapillary renal cell carcinoma.
