CD79A and neoplasm: Cell densities were calculated in the epithelial and stromal components for tumor-associated macrophages (CD68+/PD-L1+, CD68+/PD-L1−), T cells (CD3+/CD8−, CD3+/CD8+), putative T-regulatory cells (Tregs, FOXP3+), B cells (CD20+/CD79A+), plasma cells (CD20−/CD79a+), and PD-L1+ and PD-1+ cells, and compared these values with clinical factors.
