The Value of MRI in Assessing the Status of Retroperitoneal Resection Margin in Colon Cancer

May 5, 2023 updated by: Peking University Cancer Hospital & Institute

To Explore the Value of Colon MRI in Assessing the Status of Retroperitoneal Resection Margin Following Beyond Complete Mesocolic Excision Surgery for Advanced Colon Cancer

The goal of this clinical trial is to explore the value of colon MRI in assessing the status of retroperitoneal resection margin (RPRM) for advanced colon cancer.

The main questions it aims to answer are:

  • Concordance between MRI suspected RPRM positive and pathologically confirmed positive.
  • Can RPRM-positive patients undergo beyond complete mesocolic excision (CME) surgery in order to achieve R0 resection?

Participants will undergo colon MRI examination and once MRI suspects RPRM positive, they will receive beyond CME surgery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Suspected positive RPRM on MRI
Procedure: Beyond complete mesocolic excision surgery
If the participants were diagnosed with positive retroperitoneal resection margin (RPRM), they underwent beyond complete mesocolic excision surgery to ensure the R0 resection.
