Prognostic significance of CD169-positive lymph node sinus macrophages in patients with endometrial carcinoma.

ABSTRACT: Lymph node (LN) macrophages play critical roles in anti-tumor immunity, which develops via the activation of cytotoxic T cells (CTL) and NK cells. The present study aims to determine the prognostic significance of CD169(+) LN macrophages in patients with endometrial carcinoma (EC). The number of CD169(+) cells or the CD169(+) -to-CD68(+) macrophage ratio in regional LN (RLN), and the number of CD8(+) CTL or CD57(+) NK cells in tumor tissues were investigated by immunohistochemistry in paraffin-embedded tissue samples from 79 patients with EC. A high density of CD169(+) cells in the RLN of patients with EC was correlated with an early clinical stage or no LN metastasis. A high number of CD169(+) cells and a high CD169(+) -to-CD68(+) macrophage ratio were significantly associated with longer
