EPCAM and colon carcinoma: This association in the G2 colon carcinomas remained significant in a multivariate analysis including Ep-CAM expression (OR 11.175, 95% CI 3.327–37.534, P<0.0001), the lymph node status (OR 3.169, 95% CI 1.768–5.680, P=0.0001), vascular invasion (OR 2.408, 95% CI 1.345–4.309, P=0.0031), whereas postoperative chemotherapy (OR 0.772, 95% CI 0.421–1.413, P=0.4006) showed no statistical significance.
