As shown in Supplementary Table 1, RMRP levels in gastric cancer tissue were significantly associated with Borrmann type (P = 0.002), tumor invasion (P = 0.037), lymphatic metastasis (P = 0.014), perineural invasion (P = 0.008), tissue carcinoembryonic antigen (CEA) levels (P < 0.001), and carbohydrate antigen 19–9 (CA19–9) levels (P = 0.003). This evidence concerns the gene CEACAM5 and gastric cancer.
