Significance of Clinicopathology and Expression of Heat Shock Protein 72 in Human Primary Lung Carcinomas

Heat shock protein 72 (HSP72) and glycoprotein 96 (gp96) are highly expressed in cancer tissues. Recent studies indicate the possible roles of HSP72 and gp96 in the development and progression of lung carcinomas but detailed information is still ambiguous. The aim of the study is to investigate the correlation between clinicopathology and immunolocalization of HSP72 and gp96 in human lung carcinoma. Immunohistochemistry demonstrated that HSP72 and gp96 expression in lung carcinomas with metastasis was significantly higher than those with non-metastasis. HSP72 and gp96 expression were significantly associated with the presence of tumor infiltration, lymph node and remote metastasis.
