Aim: Hsp90-β and annexin A1 have been demonstrated to be associated with tumorigenesis. However, the effect of Hsp90-β and annexin A1 in lung cancer remains poorly understood. In this research, the correlation of Hsp90-β and annexin A1 in lung cancer patients were analyzed.
Methods: The expression levels of Hsp90-β and annexin A1 were examined by immunohistochemistry and ELISA.
Results: Lung cancer tissues and serum exhibited higher co-expression of Hsp90-β and annexin A1 than control groups (p < 0.05). Hsp90-β and annexin A1 could discriminate lung cancer from the control groups (sensitivity of Hsp90-β was 80.2% in tissues and 96% in serum; specificity of Hsp90-β was 80% in tissues and 83.33% in serum; sensitivity of annexin A1 was 68.76% in tissues and 95.23% in serum; specificity of annexin A1 was 75% in tissues and 85.7% in serum) and multi-index combined detection had a better diagnostic value.
Conclusion: The expression levels of Hsp90-β and annexin A1 positively correlated and such co-overexpression of Hsp90-β and annexin A1 contributed to lung cancer diagnosis.
