Prognostic implication of systemic inflammatory markers in young patients with resectable colorectal cancer

ABSTRACT

Purpose@#The prognosis of young colorectal cancer (CRC) patients has not fully been addressed. The prognostic significance of systemic inflammatory markers was examined in those patients. @*Methods@#A total of 965 patients with resectable CRC were divided into young (≤ 50 years, n = 101) and old groups (>51 years, n = 864). Neutrophil-to-lymphocyte ratio (NLR) > 5, derived NLR (dNLR) > 3, lymphocyte-to-monocyte ratio (LMR) 150, and prognostic nutritional index (PNI) 5, LMR 3 and those markers showed significance for PFS. LMR 150 (HR, 1.45; P = 0.036) and PNI < 45 (HR, 1.73; P = 0.002) were significant markers for PFS. @*Conclusion@#Systemic inflammation might be one of biologic factors that influence on prognosis of young CRC.
