Abstract:
Objective To explore the influence of ICAM-1 and LFA-1 on the breast cancer metastasis and provide scientific base for studying the molecular mechanism of breast cancer metastasis by observing the expression of ICAM-1(intercellular adhension molecule1) and LFA-1(Lymphocyte function related antigen 1) in different time different metastasis stage of breast cancer. Methods We observed the expression of ICAM-1 and LFA-1 in breast cancer tissue as well as the expression of ICAM-1、LFA-1 and VEGFR-3 in Lymphatic vessel endothelial cell of nearby the breast cancer tissues from the patients of the operation in the defferent stages with the methods of HE staining and immunohistochemistry staining. Results The positive rate of ICAM-1 and LFA-1 expression in cancer cell and cancer nest of breast cancer was increased gradually along with the increase of clinical stages and the occurrence of lymph node metastasis. And the positive rate of ICAM-1、LFA-1 and VEGFR-3 expression in lymphatic vessel endothelial cell of nearby the breast cancer tissues was increased gradually too along with the increase of clinical stages and the occurrence of lymph node metastasis,which has the positive correlation,and it has the positive correlation that the ICAM-1 and LFA-1 expressed in Lymphatic vessel endothelial cell of nearby the breast cancer tissues(P0.05).Conclusion The ICAM-1 and LFA-1 were related with breast cancer lymph metastasis,and the ICAM-1 and LFA-1 promoted breast cancer lymph metastasis through synergism each other.The increase or decrease of ICAM-1 and LFA-1 expression in the breast cancer tissue and lymphatic vessel endothelial cell of nearby the breast cancer tissues could as the data target to display certain instruction function for prevention and treatment of breast cancer lymph metastasis.The Lymphatic vessel quantity of nearby the breast cancer tissues was increased along with tumor progress, which may be related with breast cancer lymph metastasis.VEGFR-3 has the high specificity in the lymphatic vessel endothelial cell expression,and may act as the lymphatic vessel as the lymphatic vessel endothelial cell specific marker.
