As a result, a low positive p-HSP27 ratio (hazard ratio [HR] = 2.135; 95% confidence interval (CI) = 1.089–4.523; P = 0.0265) and the histological type of poorly differentiated adenocarcinoma (HR = 2.972; 95% CI = 1.309–6.470; P = 0.0103) were found to be independently correlated with worse survival (Table 2). Here, HSPB1 is linked to adenocarcinoma.
