The results in Table 8 show that TNFSF11 gene rs9533156 site variants and gastric cancer clinical factor analysis results show that, compared with the tumor size <2 cm group, patients with tumor size ≥2 cm and carrying rs9533156 site mutations had a higher frequency distribution, and the difference was statistically significant (P=0.022). This evidence concerns the gene TNFSF11 and neoplasm.
