Background and Objectives： Heat shock protein(HSP) 27 is a member of the small HSP family that plays a part in the epithelial cell growth and differentiation, wound healing. apoptosis and cell protection against inflammatory cytotoxic mediators. The expression of HSP27 was investigated in normal laryngeal tissue and squamous cell carcinoma of the larynx. Materials and Methods : We studied expression of HSP27 by Western blot on 20 patients of laryngeal squamous cell carcinoma. Results： HSP27 expressed in all normal and cancer tissues. In 9 cases(45%), expression of HSP27 more prominent in cancer tissue. Statistically, there were no significant difference in the expression of HSP27 in normal and cancer tissue, clinical stage and tumor differentiation. Conclusion 45% of cancer tissues was more prominent than normal tissue. But further studies on expression of HSP27 in laryngeal cancer and relationship with clinical parameter should be done.
