Among GC specimens, 122 (72.2%) showed positive expression (FPR2+) and 47 (27.8%) showed negative expression of FPR2 (FPR2−), while in corresponding adjacent normal tissues, 131 (77.5%) were FPR2− and 38 (22.5%) appeared FPR2+ (p < 0.001, Table S1). This evidence concerns the gene FPR2 and gastric cancer.
