Method: 80 cases were examined through ElivisionTM, an immune histochemistry method, for the expression of integrinα5β1 in ovarian epithelial neoplasms. The system of image analysis was used to measure the expression of this molecule quantitatively. Results:①Qualitative and semi-quantitative results: The expression levels of integrinα5β1 in the ovarian epithelial neoplasms have downward tendency in the order of benign, boundary and malignant neoplasms and there is significant difference on the expression levels of integrinα5β1 (Plt;0.01). There is significant difference on the expression levels of integrinα5β1 between the group with metastases and the group without metastases(Plt;0.01).②Quantitative examination result: The total positive cell area of the integrinα5β1 expression in the tumor has downward tendency in the order of benign, boundary and malignant cases, and the gray degree has upward tendency. Conclusions: The molecular expressions of integrinα5β1 is related to the tumor invasion and its metastases. Decreasing or lack of the expression of integrinα5β1 suggest the rapid development, high degree of malignancy and poor prognosis; The study also shows the improtance of using the computer image analysis for automatic diag
