BACKGROUND AND AIM: A new marker, CD208, was recently explored as a mature interdigitating dendritic cell (DC), and the correlation between the infiltration of CD208-positive cells and clinical factors has been reported in various types of cancers. In this study, we tried to clarify the clinical implication of CD208-positive cell infiltration in gastric cancer immunohistochemically. PATIENTS AND METHODS: A total of 128 gastric cancer patients who underwent a curative operation were enrolled. DCs in tumor nests were identified with two DC markers, CD208 and S-100 protein (S100), by immunohistochemistry. The correlation between clinicopathological features and the CD208- or S100-positive cell infiltration degree was analyzed. RESULTS: Infiltration of S100-positive cells did not correlate with the degree of CD208-positive cell infiltration. Patients with high CD208-positive cell infiltration in the peritumor had a poorer surgical outcome than those with low CD208 infiltration (p < 0.05). Multivariate analysis revealed that CD208-positive cell infiltration was not an independent prognostic factor. CONCLUSION: We showed that intratumoral CD208-positive cells, as mature DCs, had an inverse correlation to patients' postoperative outcome in gastric cancer, unlike a conventional DC marker. Evaluation of CD208-positive cell infiltration with S100-positive cell infiltration in gastric cancer is useful to predict antitumor immunological conditions in gastric cancer.
