Characterization and spatial distribution of the immune cell infiltrate in triple-negative breast cancer: a novel classification based on plasma cells and CD8+ T cells.

Stromal tumor-infiltrating lymphocytes (sTILs) are a robust prognostic and predictive biomarker in triple-negative breast carcinoma. However, the sTIL compartment comprises different cell populations. The aim of the study is to characterize the distribution of T cells (CD3+ and CD8+), B cells, and plasma cells and explore their association with outcome in the surgical specimen of 62 patients.

Study of regulatory T-cells in patients with gastric malt lymphoma: influence on treatment response and outcome.

Purpose: FOXP3+ regulatory T cells (Treg) play an essential role in modulating host responses to tumors and infections. The role of these cells in the pathogenesis of MALT lymphomas remains unknown. The aims of the study were to quantify the number of infiltrating FOXP3+ and CD3+ cells in patients with gastric MALT lymphoma at diagnosis and to study kinetics of these cells and CD20+ tumor cells after treatment and during long-term follow-up.

Expression of estrogen and progesterone receptors in the anal canal of women according to age and menopause.

Purpose: Fecal incontinence is highly prevalent, especially in menopausal women. The aim of this study was to analyze the expression of estrogen and progesterone receptors in the anal canal of women in relation to menopausal status and age.

Methods: Samples of hemorrhoidal tissue were obtained from 34 women undergoing hemorrhoidectomy.
