ASPH and metastatic malignant neoplasm in the lymph nodes: Univariate Cox regression analysis showed that ASPH expression was one of the significant prognostic factors (hazard ratio (HR) = 2.381; 95% confidence interval (CI): 1.275–4.445; p = 0.006), and the other prognostic factors included lymph node metastasis (p = 0.036) and distant metastasis (p = 0.010).
