Abstract:
To explore the role of CDC25B in pathogenesis and development of colorectal cancer and to investigate the relation between the expression of CDC25B and the clinical pathological character of colorectal cancer and the prognosis of patients. The expression of CDC25B in 168 patients with colorectal cancer and 25 patients with adenoma, and normal colorectal mucosa from 20 individuals was assayed by immunohistochemistry (S-P method). The expression of CDC25B was not detected in adenoma and normal colorectal mucosa. The expression rate of CDC25B in colorectal cancer was 71.4%(120/168). The expression of CDC25B had a positive correlation with distant metastasis and the increase of CEA,while it had no relationship with the tumor stage, grade, lymph node metastases, gender, age or the size of tumor . The patients in whom expression of CDC25B was detected had a markedly low 5-year survival rate. The results suggested that expression of CDC25B in colorectal cancer might accelerate the transformation of cell cycle,which promoted metastasis to distant organ, indicating that the expression of CDC25B might play a role in the development of colorectal cancer. The expression of CDC25B was a risk factor of poor prognosis.
