We investigated the relationship between SSH1 expression levels in GC and adjacent-to-carcinoma tissues and clinico-pathological features of GC (Table 3), and no significant correlation was found between SSH1 expression in GC tissue and sex, age, tumour size, tumour location, pathological type, pathological grade, positive lymph node ratio or AJCC stage (all P > 0.05, Table 3); there was a correlation with only lymphatic metastasis (P = 0.032; Table 3). The gene discussed is SSH1; the disease is gastric cancer.
