Tryptase-positive mast cells and CD8-positive T cells in human endometrial cancer.

In this study, we correlated the number of tryptase-reactive mast cells with the number of CD8-positive T cells in human endometrial adenocarcinoma biopsy specimens by means of immunohistochemical techniques. Results have shown that CD8-positive T cell counts correlate to tryptase-positive mast cell counts and that these parameters increase in accordance with the tumor progression of human endometrial carcinoma. These data suggest that inhibition of inflammation or manipulation of inflammatory resolution pathways may be a new therapeutic approach for the treatment of endometrial adenocarcinoma.
