In addition, we studied the role of CDKN2A in pan-carcinoma, and the findings suggested that CDKN2A might be utilized as a marker for selecting potential cancer patients for further study, and high expression of CDKN2A might also be used as a prognostic marker for specific tumors, and CDKN2A had important clinical value in a variety of tumors. This evidence concerns the gene CDKN2A and carcinoma.
