Abstract

INTRODUCTION

The frequency of metastatic renal cell cancer (RCC) is increasing and main drugs in management are anti-angiogenic tyrosine kinase inhibitors (TKI). Systemic inflammation has an important role in carcinogenesis and increase the secretion of pro-angiogenic factors. Here prognostic significance of neutrophil lymphocyte ratio (NLR), systemic immune-inflammation index (SII), prognostik nutritional index (PNI) and also change in SII during TKI therapy have been evaluated in cases with RCC treated with TKI

METHODS

Twenty eight cases with RCC treated with TKI were evaluated retrospectively. Kaplan–Meier and log-rank tests were used to detect the association between clinical/demographic findings and survival times. The most sensitive and specific values were found by ROC analysis: Prognostic significance of NLR (2,73), SII (832), SII changes and PNI (39) were detected.

RESULTS

High NLR (≥2,73) and SII (≥832) and low PNI (<39) were found to be associated with shorter PFS and OS. Decreased SII after TKI therapy was found to be associated with longer PFS and OS. In univariate analyses, ECOG performance status, NLR, SII, SII change and PNI were prognostic for OS, whereas in multivariate analyzes only SII change found to be independent factors for OS

DISCUSSION AND CONCLUSION

Decreased SII after TKI therapy was the only independent prognsotic factor in cases with TKI treated with TKI.
