About this study
Official title: Diagnostic Value of Diffusion-weighted Magnetic Resonance Imaging for Detection of Peritoneal Recurrence in Patients With High-risk Colorectal and Appendiceal Neoplasms : a Pilot Study
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.
Read the detailed description
This is a multicentric, prospective study (CHU de Québec and Hôpital Maisonneuve-Rosemont). Patients will be referred to one of six surgeons with a subspeciality in peritoneal surface oncology after their index surgery for CRC or AN. After thorough assessment, patients judged without residual peritoneal disease, but at high-risk for peritoneal recurrence, will be prospectively included in the study. Patients will be assessed with CT and WB-DWI/MRI twelve months after their index surgery. For WB-DWI/MRI, the standard protocol will include the following sequences: Patients will drink 1L of pineapple juice one hour prior to the examination in order to provide a negative intraluminal contrast. They will receive 20 mg of intravenous hyoscine butylbromide at the beginning of the MR exam in order to reduce bowel peristalsis. Sequences will include Axial et Coronal T2WI of the abdomen and pelvis, axial DWI with b values of 0, 50 and 1000 of the abdomen and pelvis, as well as Pre and post gadolinium-based contrast Axial and Coronal 3D T1WGRE. All patients included in the study will then undergo diagnostic laparoscopy, to provide correlation with imaging findings. Patients with no evidence of peritoneal recurrence on CT, WB-DWI/MRI and diagnostic laparoscopy will continue to be followed with serial CT and blood tumor markers (CEA, CA 19-9) as done on a routine basis. Patients with confirmed peritoneal disease at diagnostic laparoscopy will be further evaluated for cytoreductive surgery, with or without hyperthermic intraperitoneal chemotherapy. The study duration will be two years for all participants.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Peritoneal findings (time frame: 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2025.
