“…The neutrophils, lymphocytes, platelets, monocytes and C-reactive protein are all common inflammatory biomarkers and a great number of studies have revealed the prognostic role of NLR, PLR, LMR and GPS in tumors. Several met-analyses demonstrated that elevated pretreatment NLR was a prognostic risk factor in colorectal cancer (HR = 1.57, 95%CI: 1.39-1.78, P < 0.001)[ 36 ], gastric cancer (HR = 1.78, 95%CI: 1.59-1.99, P < 0.001)[ 37 ], laryngeal cancer (HR = 1.76, 95%CI: 1.53-2.03, P < 0.001)[ 38 ] and non-small cell lung cancer patients (HR = 2.86, 95%CI: 2.11-3.87, P < 0.001)[ 39 ]. Furthermore, the prognostic value of GPS has been verified in ovarian cancer (HR = 1.62, 95%CI: 1.38-1.91, P < 0.001), esophageal squamous cell cancer (HR = 1.66, 95%CI: 1.14-2.41, P = 0.008), colorectal cancer (HR = 2.20, 95%CI: 1.88-2.57, P < 0.001) and lung cancer patients (HR = 2.058, 95%CI: 1.51-2.80, P < 0.05) by several meta-analyses[ 14 , 40 - 42 ].…”
