“…The independent association of PNI with OS was found to be significant in 23 studies, while 13 did not found a significant relationship in multivariate analysis. Thirteen studies supported the prognostic value of PNI in gastric cancer patients [25,28,29,[37][38][39]41,45,48,50,54,56,58], one in colorectal cancer [60], one in oesophageal squamouscell carcinoma (ESCC) [53], three in lung cancer [17,35,49], one in diffuse large B cell lymphoma [52], one in hepatocellular carcinoma [26], one in osteosarcoma [31], one in digestive cancer [17], and one in cancer patients in general [17]. The relationship between PNI and CSS was assessed by five studies, and none supported the relationship.…”
