Abstract: Objective To evaluate HSP90 levels in the diagnosis and staging of gastrointestinal tumors.Method Patients with gastrointestinal tumors hospitalized from 2014 January to 2015 April were enrolled in this study.Serum level of HSP90 was detected.Results The serum HSP90 level of cancer group(112 ± 74)was significantly higher than the control groups,the area under the ROC curve of HSP90's was 0.875 and the cut-off point was 63.63 with sensitivity of 76.1％ and specificity of 92.6％.The HSP90 level in gastric cancer group(135 ±73)ng/ml was the highest,in colon cancer group was (105 ± 60) ng/ml and in rectum cancer group was(79 ± 42)ng/ml (all P ＜ 0.05).Serum HSP90 levels in moderate and low differentiated adenocarcinoma were higher than well differentiated adenocarcinoma group (P ＜ 0.05).Serum HSP90 level was higher in tumors with submucosa and serosa infiltration (P ＜ 0.05).Those with lymphatic metastasis tend to have a higher serum HSP90 level than those without.Conclusion Serum HSP90 level has a good predictive value on gastrointestinal tumor diagnosis,and it is correlated with tumor staging and infiltration status.
