Thirdly, there were statistically significant, although slightly weaker positive correlations between GFRA3, ∆β and lymph node metastasis (p = 0.028), the degree of gastric mucosa metaplasia (0.044) and also patient age at surgery (p = 0.038). Here, GFRA3 is linked to metastatic malignant neoplasm in the lymph nodes.
