Following that, the relationship between PCDHGA10 protein expression and clinicopathological characteristics such as gender, age, Laurén categorization, and differentiation, tumor size (T), lymph node metastasis (N), distant metastasis (M), and TNM stage was analyzed, and we observed that PCDHGA10 expression was associated with tumor size (p < 0.05), N (p < 0.05), M (p = 0.01) and TNM staging significantly (p < 0.001; Supplementary Table 1). This evidence concerns the gene PCDHGA10 and neoplasm.
