Tóm tắt:

This study evaluated the value of magnetic resonance imaging (MRI) in assessing the circumferential resection margin (CRM) and lymph node metastasis in rectal cancer. This cross-sectional study, conducted at Viet Duc University Hospital between October 2016 and May 2019, involved 109 rectal cancer patients, who underwent rectal resection after receiving pre-operative MRI staging. The correlation between preoperative MRI and postoperative histological analysis was evaluated regarding CRM invasion, the distance from the tumor or metastatic lymph node to the mesorectal fascia, the tumor stages (≤ T3, > T3), and lymph node metastasis.
