Lymphocyte and Immature Dendritic Cell Infiltrates in Differentiated, Poorly Differentiated, and Undifferentiated Thyroid Carcinoma

Abstract

Though a relationship between the extent of lymphocyte/DC infiltrates and the prognosis of PTCs could not be demonstrated, tumors with poor prognosis (PDCs, UCs) were characterized by markedly reduced lymphocyte/DC infiltrates. The study appears to confirm the protective role of DC and infiltrating lymphocytes against thyroid tumors.
