Background Hsp90-beta and annexin A1 were investigated as prognostic factors because of their apparent association with tumorigenesis. However, the effect of Hsp90-beta and annexin A1 in lung cancer remains poorly understood. The expressions of Hsp90-beta and annexin A1 in lung cancer and normal lung specimens were examined, and the relationships with respect to the clinico-pathological features and patient survival in lung cancer were analyzed. Methods The expression levels of Hsp90-beta and annexin A1 were examined using immunohistochemistry, in-situ hybridization, and Western blot. Results Lung cancer tissues exhibited higher expression levels of Hsp90-beta and annexin A1 than the normal tissues (p-lt;-.05), and the expression levels of the markers were significantly associated with the pathological grade and lymphatic invasion of lung cancer (p-lt;-.05). Moreover, the upregulation of Hsp90-beta and annexin A1 correlated with decreased survival (p-lt;-.05). Conclusion The upregulation of Hsp90-beta and annexin A1 were associated with poor post-surgical survival time and lymphatic metastasis of lung cancer patients. Moreover, the high expression of the markers was an independent predictor of poor outcomes.
