HSP27 and HSP70 Expression in Esophageal Squamous Cell Carcinoma

Abstract

<br /> <span style="font-size: small;">Twenty-eight specimens of Esophael squamous cell carcinoma (ESCC) were obtained by surgery procedures.The </span><span style="font-family: Times New Roman,Times New Roman; font-size: small;"><span style="font-family: Times New Roman,Times New Roman; font-size: small;">tissues were fixed in formalin and embedded in paraffin. In each case, all available hematoxylin and eosin stained </span></span><span style="font-size: small;">sections were examined and a representative block was selected. The ages of these patients ranged from 40 to 93 years, with a mean age of 60 years. Results. The histological grade of tumors was 4 well-differentiated, 19 moderately differentiated and 5 poorly differentiated. Expression of Hsp27 and Hsp70 in ESCC was demonstrated in 23 (82,14%) and 26 (92,86%) cases, respectively. Adjacent normal mucosa was positive in 11 (39,29%) samples and 9 (32,15%) samples for Hsp27 and Hsp70, respectively. No relationship between the expression of Hsp27 and Hsp70 with the clinicopathological parameters, including gender, age, surgical margin, lymph node status and tumor differentiation. The median follow-up period was 60 months. Survival analysis of patients with ESCC showed no relationship with the expression of Hsp27 and Hsp70. Conclusion. Taken together, our results demonstrate that Hsp27 and Hsp70 are expressed in ESCC tissues, but they are not good prognostic factor for patients with ESCC. </span>
