In view of the involvement of HER1 and HER2 in several malignancies such as breast cancer, ovarian cancer, non-small-cell lung cancer, head and neck cancers, gastric cancer, and hepatocellular carcinoma, it would be interesting to examine the association of SNPs tested in this study with these cancers [30, 31]. This evidence concerns the gene EGFR and hepatocellular carcinoma.
