We observed that five out of the twenty-eight cases with high p62 scores were low-grade, constituting 100% of all low-grade carcinomas studied, seven cases were intermediate-grade carcinomas (70%, seven out of ten), while for high-grade carcinomas, 16 out of the 23 cases studied had a high expression of p62 (69.6%). This evidence concerns the gene SQSTM1 and carcinoma.
