Background:
This study aimed to investigate the Bmi-1 expression and the clinical significance in colon cancer (CC).
Patients And Methods:
Bmi-1 expression in tumor tissue and the corresponding normal tissue was detected using immunohistological staining. The correlations between Bmi-1 expression and clinicopathological characteristics and the overall survival (OS) time were analyzed.
Results:
The median H-scores of Bmi-1 in CC tissues and the corresponding tissues were 80.0 (0-270) and 5.0 (0-90), with no statistically significant difference (Z=-13.7, P<0.001). Bmi-1 expression in CC tissues was not statistically correlated with any characteristics. The median OS times for CC patients with high or low Bmi-1 expression were 53.7 months and 44.9 months, respectively, with no statistically significant difference (P = 0.123). The survival rates of patients with low Bmi-1 expression were higher than those of patients with high Bmi-1 expression but the differences were not statistically significant.
Conclusion:
Bmi-1 expression in CC tissue is significantly higher than that in corresponding normal tissue. While there may be a trend towards improved survival, this is not statistically significant.
