CSNK2B and nonpapillary renal cell carcinoma: In the multivariate analysis, using an H-Score threshold of cytosolic CK2β higher or equal 41 (median value), we observed a non-significant correlation (p = 0.703) with patient survival, which indicates that cytosolic CK2β (CK2βcyt) by itself is not useful as a prognostic biomarker of ccRCC.
