Abstract
ObjectiveTo explore the expression of pre-B-cell colony enhancing factor (PBEF) in colorectal cancer, and analyze the relationship between PBEF expression and the clinical pathological characte-ristics and its diagnostic and prognostic value.
MethodsSixty-eight human colorectal tumor and normal colo-rectal tissues were collected, and the expression of PBEF was detected by immunohistochemical method. The relationship between the expression level of PBEF and the characteristics of tumors and prognosis was analyzed.
ResultsThe positive expression rate of PBEF in colorectal cancer tissues was 80.9%, higher than that in normal colorectal tissues, which was 29.4% (χ2=36.41, P<0.05). The expression level of PBEF had no relationship with age (χ2=0.11, P>0.05), sex (χ2=0.39, P>0.05), histology type (χ2=0.54, P>0.05) or penetrating serosa (χ2=1.55, P>0.05), but significantly associated with the degree of differentiation (χ2=6.29, P<0.05), metastasis of lymph node (χ2=4.32, P<0.05), distant metastasis (χ2=4.16, P<0.05) and clinical stage (χ2=7.58, P<0.05). The 5 year survival rates of patients with positive and negative expression of PBEF were 73.3% and 81.8%, and the difference was not statistically significant (χ2=0.315, P>0.05).
ConclusionThe abnormal high expression of PBEF may be closely related to the occurrence and development of colorectal cancer.
