Abstract:
Objective: To investigate the expression of Cyclin E in colorectal carcinoma and its significance.Methods: The Cyclin E expression and the cell proliferation(PI,SPF)in 30 cases of colorectal carcinomas (including tumors and normal tissues distant to the tumors)were respectively assayed with Flow Cytometry (FCM), and the relationships between the Cyclin E expressive rate and clinical pathologic features were compared. Correlaction between the Cyclin E expressive rate and the cell proliferation(PI, SPF) was analyzed too.Results: The Cyclin E positive rate and the cell proliferation in colorectal carcinoma were significantly higher than those of the distal normal tissues. As for the Cyclin E positive rate and the cell proliferation,no significant differences were found among the subgroups divided according to malignance, lymphatic metastasis and the site of tumor. There was a significant correlation between the Cyclin E positive rate and the cell proliferation.Conclusion: The Cyclin E overexpression plays an important role in the onset of colorectal carcinoma.The Cyclin E expressive rate is not consistent with the general clinical pathologic features,but with the cell proliferation. The Cyclin E expressive rate may be one of the potential prognostic indicators in coloretal carcinoma.
