HSP90B1 and metastatic malignant neoplasm in the lymph nodes: Patients in the high GRP94 expression group tended to exhibit a higher frequency of lymph node metastasis than patients in the low GRP94 expression group (P = 0.032), and patients with high GRP94 expression levels tended to present at a later disease stage than patients with low GRP94 expression levels, although the difference between these two groups was not significant (P = 0.057).
