Conclusion
MRI is moderately accurate in predicting the involvement of the circumferential resection margin in rectal cancer.
Supporting Evidence
- Beets et al. showed that a distance of 6 mm on MRI predicts a tumor distance of at least 2 mm on histology with 97% confidence.
- A crucial distance of 1 mm can be predicted by a distance of 5 mm on MRI with high confidence.
- Currently, 5 mm is the cutoff used for predicting involvement of the circumferential resection margin.
Takeaway
Doctors use MRI to see how close a tumor is to a critical area before surgery, which helps decide if a patient needs extra treatment.
