PROM1 and neoplasm: Our analysis revealed that positive expression of CD133 was significantly associated with gross tumor morphology (P = 0.034), histologic type (P = 0.008), tumor invasion (pT) (P = 0.012), lymph node status (pN) (P < 0.001), sub-class of stage III (P < 0.001), but it was not associated with gender, age, tumor site, tumor size, surgery, intestinal obstruction, serum CEA, CA199 or CA242 levels (Table 1).
