Background:Breast cancer is a major public health problem for woman. Several
studies suggestedthat development and progression of malignant tumors are
characterized by an interaction with the cells in the tumor microenvironment
including infiltrating immune cells.
Aim:The aim was to investigate relationship between tumor infiltrating
lymphocytes(TILs) in infiltrating breast carcinomaand other recognized
clinicopathological factors.
Material and Methods: 100 cases of infiltrating breast carcinomas were included in
the study.Stromal.TILs status was evaluated using hematoxylin and eosin staining.
For all statistical data chi-square test was applied using SPSS and Spearman
correlation.P‐values of less than 0.05 were considered as significant.
Results: Stromal TILs correlated with well-established prognostic markers:HER2
positivity(P=0.001),higher tumour grade (P=0.016), ER negativity (P=0.015), PR
negativity (P=0.008),lymphnode status(P=0.005) and lymphovascular invasion(LVI)
(P=0.001), molecular classification (P=0.000) , and p53 positivity (P=0.013). No
correlation between CD10 positivity or high proliferative index( KI67)and stromal
TILs.
Conclusion:Stromal TILs is directly correlated more aggressive phenotype:HER2
positivity ,ER negativity, PR negativity ,molecular classification, present LVI,
higher tumor grade and greater nodal involvement;so TILs could be used as novel
predictive and prognostic parameter and used to develop newer drugs
(immunotherapy).

Abstract: The marker of mesenchymal cells - vimentin with high and moderate expression
is present in both epithelial and stromal cells with "eosinophilic" forms of polyps and only
in the stroma in patients with "neutrophilic" polyps. The presence of high vimentin
expression indicates a high activity of mesenchymal cells. In the prognostic plan, these
changes indicate future relapses. Detection of the CD68 marker, its low and moderate
expression can mean low participation of macrophages in the formation of nasal polyps of
both forms. The presence of single stained cells in mesenchymal clusters indicates a low
phagocytic activity. The high and moderate expression of CD45 in mesenchymal clusters
located in “eosinophilic” polyps confirms our assumption that these mesenchymal clusters
are a “growth zone” of formations. High and moderate expression of CD138 in mature
epithelial cells in all tissue samples of both forms of polyps and the lack of expression of
this marker in clusters of mesenchymal formations, as well as average expression in cells
located in the stroma, may indicate the origin of the latter from active mesenchymal cells.
With the "eosinophilic form" of polyps, moderate and high expression of CD34 is detected.
These results confirm our assumption about the formation of a new vascular system in
mesenchymal clusters. Near the epithelium and in the stroma, a well-developed vascular
system is also observed. An increase in the number of vessels is a sign of recurrence, and
an increase in the number of newly formed vessels is prognostically unfavorable and
indicates the occurrence of relapse.
