When MGMT, MSH2, MLH1 were evaluated in terms of 50–100% follicular cell positivity, although there was no statistically significant difference, papillary carcinoma cases showed a higher rate of follicular cell positivity, as seen in Table 2, and this difference was more pronounced between papillary carcinoma and colloidal goiter. Here, MGMT is linked to thyroid gland papillary carcinoma.
