Abstract

Abstract Background: Breast carcinoma, the most common malignancy in women, are often accompanied by tumor infiltrating lymphocytes (TIL) which has controversial clinical relevance. TIL is thought to reflect the host’s immune response to malignant tumors. FOXP3, specific biomarker of Treg, is an important transcription factors that develops and functions in the maintenance of self tolerance, including inhibition of CD8+ cytotoxic T cell function. Aim: To analyze the differences and the correlation between FOXP3+ and CD8+ TIL in breast carcinoma with different T staging. Methods: An analytical observational research, performed on 44 paraffin block of breast carcinoma of various stages T (AJCC 7th ed) in anatomical pathology installation of RSUD Dr. Soetomo, used FOXP3+ and CD8+ antibodies. The immunoexpression are evaluated on stromal area, then analyzed statistically, period January 1, 2014 – December 31, 2016. Result: Showed significant differences in FOXP3+ expression between T1-T4, T2-T3, T2-T4, T3-T4. There were significant differences in CD8+ expression between T2-T3, T2-T4. There is a correlation between the expression of FOXP3+ and CD8+ in T1 and all T (p < 0.05). Conclusion: There was significant difference in FOXP3+ and CD8+ TIL of breast carcinoma with increasing T stage. There was correlation between FOXP3+ and CD8+ TIL expression of breast carcinoma at all T and T1 stage.
