Purpose: Heat shock proteins (HSPs) are highly conserved molecular chaperones. There are various studies that assess the prognosticvalue of HSPs in patients with esophageal cancer, but the conclusion remains controversial. This is the first meta-analysisstudy aiming to summarize the evidence on the suitability of HSPs to predict patients’ survival. Materials and Methods: Searching PubMed, Web of science and Medline until May 31, 2014, data were compared for overall survivalin patients with down-regulated HSPs level with those with up-regulated level. We conducted a meta-analysis of 9 studies(801 patients) that correlated HSPs levels with overall survival. Data were synthesized with hazard ratios (HRs). Results: The estimated risk of death was 2.93-fold greater in HSP27 negative patients than HSP27 positive patients [95% confidenceinterval (CI), 1.12–7.62]. When limited to esophageal squamous cell carcinoma (ESCC), the risk of death in HSP27 negativepatients seemed more significant (HR, 3.90; 95% CI, 2.35–6.49). Decreased expression of HSP70 was also associated with worsesurvival in esophageal cancer (HR, 2.83; 95% CI, 1.90–4.23) and, when limited to ESCC, HR was 3.21 (95% CI, 1.94–5.30). Data collected,however, were not sufficient to determine the prognostic value of HSP90 in patients with ESCC nor esophageal adenocarcinomas(EADC). Conclusion: In this meta-analysis, reduced HSP27 and HSP70 expressions were associated with poor survival in patients withesophageal cancer, especially esophageal squamous cell carcinoma.
