[Histological and immuno-morphological characteristics of differentiated cancer of the thyroid gland]

Histological and immunomorphological study of the removed tumor and tissue of the thyroid was performed in 80 patients with differentiated thyroid cancer. Activation of immune reactions and immunocompetent cells was reported at the border with blastomatous process. The latter seems a factor contributing to a favorable run of differentiated thyroid cancer. The capacity of papillary and follicular cancer for multifocal growth limits indications for preserving surgery in such lesions.
