  • Relationship Between Strong Immunoreactivity of Focal Adhesion Kinase and Invasion and Metastasis in Human Gastric Carcinoma

    【Abstract】Objective To study the correlation between focal adhesion kinase (FAK) expression and biological behavior of invasion and metastasis in gastric carcinoma. MethodsThe immunoreactivity of FAK was revealed by immunohistochemical method in gastric carcinoma tissues,canceradjacent tissues, normal gastric mucosa,and 200 regional lymph nodes in 50 collected specimens when radical resection of gastric carcinoma were carried out. ResultsThe percentage of FAK bly positive immunoreactivity were 10.0%(5/50), 20.0%(10/50) and 78.0%(39/50) in normal gastric mucosa, cancer-adjacent tissues and gastric carcinoma tissues respectively. The b immunoreactivity was obviously higher in gastric carcinoma tissues than that in normal gastric mucosa or canceradjacent tissues (P<0.01). There were no difference between normal gastric mucosa and canceradjacent tissues (Pgt;0.05). The percentage of bly positive immunoreactivity of FAK were 68.8%(22/32) and 33.3%(6/18) in cases with metastasis and without metastasis of lymph node respectively. The immunoreactivity of FAK in cases with metastasis of lymph node was significantly higher than that without metastasis of lymph node (P<0.05).The b immunoreactivity of FAK were 87.2%(136/156) and 40.9%(18/44) in withmetastatic lymph node and withoutmetastatic lymph node. The immunoreactivity of FAK in withmetastatic lymph node was significantly higher than that withoutmetastatic lymph node (P<0.01). The percentage of FAK bly positive immunoreactivity showed correlation with the cellular differentiation and depth of infiltration of gastric carcinoma. The deeper infiltration and lower differentiation, the ber expression rate was obtained (P<0.05), which showed no correlation with Borrmann type, location and size of tumor (Pgt;0.05). ConclusionIncreased immunoreactivity of FAK is an important role of invasion and metastasis for gastric carcinoma cells. Detection of FAK expression in cancer tissues can be helpful to understand the carcinogenic biological behavior of gastric carcinoma as well as to make judgment and treatment of prognosis of patients.
