SSH1 and neoplasm: In the multivariate Cox regression model, tumor size (HR = 1.429, p = 0.007), lymphovascular invasion (HR = 1.692, p = 0.003), recurrence (HR = 3.856, p < 0.001), progression (HR = 2.655, p < 0.001) and SSH-1 positive expression (HR = 1.558, p = 0.015) were significant variables of CSS (Table 2).
