On the other hand, high CD133 staining was detected in 16 (64%) of the 25 stage 1, 12 (28%) of the 43 stage II and in 37 (54%) of the 69 more advanced stage 3 cancers and cross-tab analysis identified a significant correlation (p = 0.006) between the two parameters (Table2). Here, PROM1 is linked to cancer.
