KRT5 and metastatic malignant neoplasm in the lymph nodes: Evaluated by logistic statistical method, the HSPA8 expression was related to lots of clinical characteristics of poor prognosis, for example, AJCC stage (OR = 5.846, 95% CI = 2.322–15.641, P < 0.001), lymph node metastasis (OR = 6.361, 95% CI = 2.021–28.238, P = 0.004), CK5/6 expression (OR = 7.666, 95% CI = 2.439–34.021, P = 0.002), and HSPA8 expression (OR = 3.991, 95% CI = 1.601–10.733, P < 0.05) (Table 1).
