While tumor infiltrating T lymphocytes were more abundant than B cells in the tumor epithelium, infiltrating T and B cells were both more common in the tumor epithelium of the low-volume ascites group based on staining for CD20, CD8, and CD3 (P = 0.02, P = 0.001, and P = 0.01) (Table 2). Here, CD8A is linked to neoplasm.
