[Morphometric characteristics of the immunomorphological reactions in metastasizing and nonmetastasizing thyroid cancers].

Morphometrically, immunomorphological reactions have been studied on the intraoperative material from 70 patients with thyroid cancer of various histological pattern. It was found that metastasization of cancerous tumors proceeds on the background of suppressed antitumor immunity--a reduced index of the stroma lymphoid infiltration, diminishing of the T-dependent paracortical zone of regional lymph nodes and less content of T-lymphocytes and macrophages in it.
