Prognostic value of tumor-infiltrating T-lymphocytes density in the therapeutic response to initial platinum-based chemotherapy in patients with non-small cell lung cancer

Background/Aim. The fact that lung carcinomas, like other solid tumours, can be immunogenic, may have a substantial prognostic value in non-small cell cancer. Specific cytotoxic T-lymphocytes demonstrated most patients with primary tumours of different histological types. Two main groups participate the coupled recognition tumour-specific antigens - (CD8+, cluster differentiation 8) and helper (CD4+, 4). goal this research was to assess relationship between tumour infiltration therapeutic response initial chemotherapy. Methods. Data were obtained from cancer whose after four cycles platinum chemotherapy observed relation density tumour-infiltrating (CD4+ CD8+) small biopsy samples. assessed line RECIST 1.1. evaluation system. Based on expected response, divided into three following groups: favourable (complete partial regression), stable disease progression patients. To CD4+ CD8+ T-lymphocytes, number lymphocytes determined at x200 (1.1mm2) magnification. Three visual fields dense lymphocyte infiltrate selected for counting, values all individual added up. mean value, samples classified score 0, 1, 2 3.

Results. results did not show any difference distribution epithelial components therapeutical (?2=2,977; p= 0.226). Also, there significant component (?2=1,329; p=0.515). There no influence stromal (?2=0,606; p=0.739) also, (?2=5,167; p=0.076). Conclusion. prove level (non-small cancer) had better standard
