In recent years, several inflammation-based and nutritional markers have been developed, and many studies have revealed that preoperative values for these markers, such as C-reactive protein-to-albumin ratio (CAR) [8, 9, 10], neutrophil-to-lymphocyte ratio (NLR) [11, 12, 13], platelet-to-lymphocyte ratio (PLR) [14, 15, 16], Prognostic Nutritional Index (PNI) [17, 18, 19], Glasgow Prognostic Score (GPS) [20, 21, 22], and prognostic index (PI) [23, 24, 25], have prognostic value for various cancers, including gastric cancer. This evidence concerns the gene CRP and gastric cancer.
