About this study

To demonstrate the potential role of dual-energy computed tomography (DECT) by iodine maps data, aimed at discriminating colon cancer from colon wall pseudo-thickening.

Read the detailed description

Prospectively, 50 consecutive patients with pathology-proved colorectal tumor (detected by optical colonoscopy) who undergo routine thoraco-abdominal DECT for initial staging in the Department of Radiology at our institution from April 2020, will be included. The exclusion criteria are as follows: patients with body mass index (BMI) above 30 kg/m2, patients with renal insufficiency (estimated glomerular filtration rate < 30 ml/min), allergy to iodinated contrast and a known history of previous abdominal radiotherapy.

All patients will undergo a staging enhanced thoraco-abdominal CT by 256-slices CTs (Revolution CT, GE healthcare) at Fribourg hospital. DECTs will be acquired without an enema, rectal insufflation or oral contrast to have collapsed colorectal wall for further measurements and to simulate routine clinical practice. No additional screening procedures, such as a laboratory or diagnostic tests are necessary for the present study.

Upon acquiring 50 patients, CT quantitative assessments will be performed. Initially, data will be transferred to AW Advantage workstations (GE Healthcare). Thereafter, for each patient, the iodine map images will be created by post-processing by. All CT quantitative measurements will be performed independently by two radiologists. Three regions of interest (ROI) will be applied to colorectal tumor and the normal collapsed colorectal wall (confirmed previously by colonoscopy) and consequently, the mean of these measurements will be reported. These measurements correspond to mean iodine uptake of colorectal tumor and normal collapsed wall, respectively. Finally, the iodine uptake of the tumoral lesion and normal collapsed wall in each patient will be compared to demonstrate the significant difference in iodine uptake. Investigators anticipate that the obtained cut-off value will be a new benchmark in clinical practice, to exclude the colorectal tumors on non-prepared collapsed colon wall and eliminate the need for a complementary colonoscopy.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Adenocarcinoma, run by Hôpital Fribourgeois at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Difference of iodine uptake (time frame: 3.11.2021). 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 4 Aug 2022.
