The Relationship between the serum intercellular adhesion molecule-1 level and the prognosis of the disease in lung cancer / 대한내과학회지

ABSTRACT

BACKGROUND: Adhesion molecule is related to cell-cell interaction and inflammatory interaction. In addition, adhesive interactions between tumor cells and adjacent cells and/or extracellular matrix are important role in the complex process of tumor growth and develpment. Of these adhesion molecules, expression of intercellular adhesion molecule-1 (ICAM-1) have been identified in colon cancer, bladder cancer, lung cancer, melanoma, pancreatic cancer, hepatocellular carcinoma. In the current study, we analyzed serum ICAM-1 concentrations to investigate the relationship between the sICAM-1 level and the prognosis of the disease in patients with lung cancer METHODS: Serum sICAM-1 was measured in 84 patients with lung cancer according to the pathologic types and clinical staging using ICAM-1 ELISA kit. The Kaplan-Meier method was used to analyse survival time. RESULTS: There was no difference in sICAM-1 concentration among the stage of lung cancer. And no difference was observed among histologic tumor types with regard to sICAM-1 concentration. The overall survival of patients with low sICAM-1 concentration (or=306 ng/mL) in non-small cell lung cancer patients, but no difference was observed in small cell lung cancer patients. CONCLUSION: These results suggest that high levels of sICAM-1 reflect the poor prognosis of patients with non-small cell lung cancer.
