On the other hand, in papilliferous thyroid carcinomas,Chen et al.3 observed a correlationbetween the immunoexpression of the protein P53 and that of EGFR, i.e. there wasco-overexpression that also coincided with the presence of compromised lymph nodes,tumor size and more advanced staging. The gene discussed is EGFR; the disease is thyroid gland carcinoma.
