A total of 55 ccRCC patients were divided into two groups based on the immunohistochemistry EGR1 scores: the high EGR1 expression group (n = 16) (scores >4 are considered a high expression) and the low EGR1 expression group (n = 39) (scores <4 are considered a low expression). This evidence concerns the gene EGR1 and nonpapillary renal cell carcinoma.
