Abstract

Objective: Determine the value of magnetic resonance in the invasive assessment of the circumferential resection margin compared with the pathological results and comment on the relationship of some factors with circumferential resection margin status.  Methods: Prospective cross – sectional description. Results: The sensitivity, specificity and accuracy of magnetic resonance in the invasive assessment of the circumferential resection margin compared with the pathological results were: 33,3% (95% CI: 4,3 – 77,7%); 93,7% (95% CI: 84,5 – 98,2%) và 88,4% (95% CI: 78,4 – 94,9%). Recording the factors: tumor location (p<0,05); intestinal wall invasion (T) on magnetic resonance (p<0,001) and tumor diameter (p<0,001), lymph node metastasis (N) (p<0,01); perineural invasion (p<0,05) at pathology was associated with circumferential resection margin status (the difference was statistically significant). Conclusion: The specificity and accuracy of magnetic resonance in the invasive assessment of the circumferential resection margin were quite high; however the sensitivity was still low. The risk factors associated with circumferential resection margin status were: tumor location, tumor diameter, intestinal wall invasion (T), lymph node metastasis (N) and perineural invasion.
