Abstract:
Objective To investigate the association between extramural vascular invasion (EMVI) detected by multi-detectors computed tomography (MDCT) with contrast enhanced (ceMDCT) and clinicopathologic characteristics in patients with colon cancer.Methods Between February 2009 and December 2013,patients with histologically proven primary colon cancer and undergoing curative resection were included in this retrospective study.According to American Joint Committee on Cancer TNM staging system,patients of stage Ⅱ and Ⅲ were included in this study.EMVI status detected by MDCT (ctEMVI) was defined according to the EMVI scores.Chi-square test was used to analyze the association between clinicopathologic characteristics and ctEMVI.Results 165 stage Ⅱ and stage Ⅲ patients were included in this study as confirmed by pathology based on AJCC.Positive ctEMVI was demonstrated in 51 patients (34.5％,51/165).There were significant association between positive ctEMVI and age ＜ 65 years (x2 =4.810,P =0.031),ceMDCT defined tumor stage (x2 =17.911,P =0.000),ceMDCT defined metastatic lymph node (x2 =5.436,P =0.022),tumor size≥5 cm (x2 =3.799,P =0.036) and pathological T stage (x2 =13.346,P =0.001).Conclusions EMVI,detected by ceMDCT,is significantly associated with age,tumor size and T staging in colon cancer.
