Clinicopathologic significance of tumor microenvironment CD11c, and FOXP3 expression in diffuse large B-cell lymphoma patients receiving rituximab, cyclophosphamide, anthracycline, vincristine, and prednisone (R-CHOP) combination chemotherapy

Abstract

BACKGROUND/AIMS: CD11c is a dendritic cell marker in humans, which potentially induces a cytotoxic effect on lymphoma cells. Forkhead boxP3 (FOXP3) is a regulator of T lymphocyte in the microenvironment of the lymphoma. The principal objective of this study was to determine whether the tumors' microenvironment expressions of CD11c and FOXP3 are predictive of clinical outcomes in diffuse large B-cell lymphoma (DLBCL) patients receiving treatment with rituximab, cyclophosphamide, anthracycline, vincristine, and prednisone (R-CHOP) combination chemotherapy. METHODS: The study population consisted of 100 patients with DLBCL. The CD11c and FOXP3 expression in primary tumors' microenvironment were evaluated using an immunohistochemistry (IHC). RESULTS: = 0.039) between the two groups. CONCLUSIONS: We can achieve possible clinical significance of lymphoma tumor microenvironments through CD11c and FOXP3 IHC stains in extranodal DLBCL patients receiving R-CHOP therapy.
