AIM:To verify that CD markers are available for detecting cancer stem cell populations and to evaluate their clinical significance in colon ***:Immunohistochemistry for CD133,CD24 and CD44 was performed on the tissue microarray of 523 colorectal *** records were reviewed and clinicopathological analysis was ***:In colorectal adenocarcinoma,128 of 523 cases(24.5%) were positive and 395 cases(75.5%) were negative for CD133 *** hundred and sixty-four of 523 cases(50.5%) were positive and 259 cases(49.5%) were negative for CD24 *** hundred and two of 523 cases(96%) were negative and 21 cases(4%) were positive for CD44 *** clinicopathological analysis,CD133 expression was present more in male patients(P = 0.002) and in advanced T stage cancer(P = 0.024).Correlation between CD24 expression and clinicopathological factors was seen in the degree of differentiation(P = 0.006).Correlation between CD44 expression and clinicopathological factors was seen in the tumor size(P = 0.001).Survival was not significantly related to CD133,CD24 and CD44 ***:CD markers were related to invasiveness and differentiation of colorectal ***,CD expression was not closely related to survival.
