Diagnostic Value of Diffusion-weighted Magnetic Resonance in High-risk Colorectal and Appendiceal Neoplasms
Canada30 participantsStarted 2022-09-01
Plain-language summary
Diffusion-weighted magnetic resonance imaging (DWI/MRI) has been described in recent literature as a highly sensitive and specific modality for the detection of peritoneal metastases PM. It has been demonstrated to be superior to CT for patients with known peritoneal disease from colorectal and gynaecological malignancies as a staging tool for cytoreductive surgery. It was also demonstrated to be superior for the detection of PM for gastric cancer patients otherwise considered with a resectable tumor. However, the literature is scarce on the role of DWI/MRI in the detection of peritoneal recurrence for patients with high-risk features, either colorectal cancer (CRC) or appendiceal neoplasms (AN).
The aim of this study is to prospectively assess the added value of whole-body DWI/MRI (WB-DWI/MRI) to CT and diagnostic laparoscopy for detection of PM in the follow-up of patients presenting with CRC or AN and high-risk features for peritoneal recurrence and evaluate how it correlates with intraoperative findings.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Confirmed diagnosis of colorectal cancer or high-risk appendiceal neoplasm (High grade Appendiceal Mucinous Neoplasm (HAMN), goblet-cell carcinoma or adenocarcinoma).
* No evidence of residual peritoneal disease based on referring surgeon operating report and preoperative imaging.
* At least one high-risk feature for peritoneal recurrence, including:
* Synchronous peritoneal metastases resected at index surgery;
* Synchronous ovarian metastases resected at index surgery;
* Perforated primary tumor.
* No evidence of distant metastases.
* Patient fit for cytoreductive surgery, if required (ECOG 0 or 1).
Exclusion Criteria:
* Unresected synchronous peritoneal metastases at referral.
* Low grade Appendiceal Mucinous Neoplasm (LAMN).
* No high-risk feature for peritoneal recurrence.
* Evidence of distant metastases on preoperative imaging.
* Patient who is unable to have MRI.
* Patient unfit for cytoreductive surgery, if required (ECOG 2 or more).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
