HSPD1 and metastatic malignant neoplasm in the lymph nodes: HSPD1 protein level showed an impact on disease-specific survival (DSS) [adjusted hazard ratio (AHR) = 3.85, 95% confidence interval (CI) = 2.28–6.50, p < 0.001, Table 2] and disease-free survival (DFS) (AHR = 2.00, 95% CI = 1.22–3.29, p = 0.006, Table 2) in BMSCC patients having N1 and N2 lymph node metastasis compared to those patients having no lymph node invasion (N0).
