MS4A1 and neoplasm: To evaluate the prognostic impact of tumor-infiltrating CD20+ B cells, CD8+ T cells, DC-LAMP+ DCs and B cell/CD8+ T cell interactions in both intratumoral and stromal compartments of OPSCC samples, we investigated overall survival (OS) upon stratifying the patient cohort based on the median of positive cells per 1 mm2 of the tumor nest and the tumor stroma area.
