Effect of Magnetic Resonance Imaging on Multidisciplinary Meeting decision and the outcome of Rectal Cancer

Le résumé fourni par la source

Objectives: To evaluate the accuracy of Magnetic Resonance Imaging [MRI] in local staging of rectal cancer and effect on management and outcome. Background: MRI is currently considered the best modality for primary staging of rectal cancer, post chemoradiotherapy, follow up, tailoring surgery and follow-up. Methods: This was a retrospective study that included 130 cases diagnosed with rectal cancer. All patients had an MRI with a dedicated protocol for local staging. Multidisciplinary meetings [MDM] were held regularly for decision making along the journey of the tumour management. Regular post-operative surveillance was performed to rule out recurrence. Analysis of the outcome was done for each case after 3 years from first MDM. Results: Comparing the result of surgical specimen with the preoperative MRI revealed good results regarding tumour [T] staging. The total accuracy was 93.4% for T stage. To some extent MRI showed lower accuracy for lymph node evaluation that was 69.7%. After 3 years follow-up, the recurrence rate of tumour was only about 5% for the surgical approach which was the decision 105 cases. Non-surgical approach exhibited promising outcome and it was a choice for 25 cases. MRI was the corner stone at each MDM discussion and in decision making. Conclusion: MRI can be considered a reliable modality for primary staging of rectal cancer cases, follow-up after CRT, operative planning and post-operative follow-up. Depending upon MRI in decision making helps in decreasing recurrence rate of rectal cancer even with less aggressive operations and non-operative management.
