e17519 Background: The purpose of our study was to investigate prognostic role of neutrophil to lymphocyte ratio (NLR), derived neutrophil to lymphocyte ratio (dNLR), platelet to lymphocyte ratio (PLR), and lymphocyte to monocyte ratio in PFS and OS, and immunological tumor’s microenvironment in patient with HNSCC. Methods: We analysed medical records an tumor samples of 60 patients with HNSCC with stage I - IVB (37 men, 23 women; median age 59). All patients were under standard clinical complex protocol. All patients were under our supervision from 2010 to 2015. We examined demographic data, clinical stage, tumor morphological characteristics and specific level of expression of CD8(+) T-cells, in the tumor and microenvironment, and baseline level of WBC, neutrophil, lymphocyte, monocyte and PLT . Also we analysed calculated value of NLR, dNLR, PLR, and LMR. Results: The median value of NLR was 2.03 (95% CI: 1.66-2.59), dNLR - 1.44 (95% CI: 1.23-1.70), PLR - 144.58 (95% CI: 107.59-179.32) and LMR - 6.79 (95% CI: 5.34-8.17). Median of 1-year OS and PFS was non significantly lower in pts with NLR < 2.03 (16.0 vs 18.0 month, p = 0.6020 and 5.00 vs 7.00 month, p = 0.5383). But NLR correlate with expression of CD8(+) T-cell in tumor (p = 0.05). Median of 1-year OS was the same in both group (16.0 vs 17.0 month, p = 0.5453), PFS was non significantly lower in pts with dNLR < 1.44 (16.0 vs 18.0 month, p = 0.6020 and (5.00 vs 7.00 month, p = 0.7435). NLR correlate with expression of CD8(+) T-cell in tumor (p = 0.0337). Analyse of LMR showed trend of best 1-year OS in pts with LMR < 6.79 (18.0 vs 15.0 month, p = 0.4674) and equal PFS (6.00 vs 7.00 month, p = 0.4914). PFS and 1-year OS were better (nonsignificant) in pts with PLT > 144.58 (9.0 vs 5.0 month, p = 0.5854) and (18.0 vs 16.0 month, p = 0.5836). Conclusions: Important role of indicators of systemic inflammation is obvious for patient with HNSCC, but our study showed that only baseline characteristics couldn’t be strong prognostic factors by different degree of intratumor inflammation.
