Predictive Factors of Positive Circumferential and Longitudinal Margins in Early T3 Colorectal Cancer Resection.

Multivariate logistic regression revealed that invasion of pericolorectal tissue/serosa was the independent predictor factor for positive CMR ( P < 0.001), with the marginal significance of infiltrative gross pattern ( P =0.055), while signet ring type was the independent predictor factor for positive LRM ( P =0.035) with the marginal significance of high MVD ( P =0.53) and sinusoidal vascular pattern ( P =0.54) ( Table 4 ). 4.
