Abstract
Objective To explore the role of intercellular adhesion molecule-1(ICAM-1) in the metastasis of lung cancer.Methods The expression of ICAM-1 in the tissue and the serum ICAM-1(sICAM-1) level in the 52 cases of primary lung cancer were detected with immunohistochemical staining method(SP) and enzyme linked immunosorbent assay(ELISA),with 20 cases of adjacent non-cancerous tissue as the control.Results The positive rate of ICAM-1 expression in lung cancer was significantly higher than that of adjacent non-cancerous tissue.The expression of ICAM-1 in the cases with lymph node metastasis was higher than that of no lymph node metastasis.The expression of ICAM-1 in stage III+IV was higher than that of stage I+II,and that in adenocarcinoma was higher than that of squamous cell carcinoma.The level of sICAM-1 in patients with lymph node metastasis was higher than that without lymph node metastasis.The sICAM-1 level in patients of adenocarcinoma was higher than that of squamous cell carcinoma,and that in patients with positive expression of ICAM-1 in tissue was higher than that of negative expression of ICAM-1.Conclusion The expression of ICAM-1 may be associated with the metastasis in lung cancer.The sICAM-1 level reflects the expression of ICAM-1 in tissue and may be used as a tumor marker of metastasis and prognosis in lung cancer.
