Right, the biggest concern I have with these MRI directed therapies is the ability of community radiologists to accurately interpret rectal MRIs and accurately detect EMVI , proximity to CRM, and accurately diagnose lateral pelvic lymph nodes. This is why the Mercury study approach has not be widely adopted in the United States. We also routinely have rectal cancer patients managed by general surgeons and who knows whether these patients are getting a quality TME. Is this approach safe to implement outside of practice settings with strong colorectal multi-disciplinary care and experienced radiologists?
