Trial summary

Contrast-enhanced intraoperative ultrasound (CE-IOUS) during surgery for colorectal liver metastases (CLM) has become a part of clinical practice. However, if it should be selectively or routinely applied remains unclear. This study is carried out to clarify which are the criteria for a selective use of CE-IOUS if any.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 29 to 85 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Consecutively enrolled patients with CLM who underwent surgery and during this procedure received IOUS and CE-IOUS.

Who may be able to join

  • consecutively enrolled patients with CLM who underwent surgery and during this procedure received IOUS and CE-IOUS.
  • each patient had at least 6 months of postoperative follow-up.

Who cannot join

  • patients who after IOUS and CE-IOUS had explorative laparotomy only were excluded from the analysis since there was no histological confirmation of the tumor and most of them were lost to surgical follow-up

About this study

Official title: Factors Influencing the Impact of Contrast-Enhanced Intraoperative Ultrasound During Liver Surgery for Colorectal Cancer Liver Metastases

Contrast-enhanced intraoperative ultrasound (CE-IOUS) during surgery for colorectal liver metastases (CLM) has become a part of clinical practice. However, if it should be selectively or routinely applied remains unclear. This study is carried out to clarify which are the criteria for a selective use of CE-IOUS if any.

Read the detailed description

Contrast-enhanced intraoperative ultrasound (CE-IOUS) during surgery for colorectal liver metastases (CLM) is entered in clinical practice. However, its impact seems to decrease with the improvement of preoperative imaging. Therefore, if CE-IOUS should be selectively or routinely applied remains unclear: a profile of patients who may benefit of CE-IOUS application has to be disclosed. The aim of this study is to define reliable criteria for a selective use of CE-IOUS during surgery for CLM. IOUS is performed using 3-6 MHz convex probe, and a 7.5-10 MHz micro convex probe. Staging is completed by CE-IOUS using the standard 3-6 MHz convex probe and the dedicated 1.88-3.76 MHz harmonic frequency probe. In all patients, 2.4 mL of sulphur-hexafluoride microbubbles (SonoVue®, Bracco, Milan, Italy) are injected through a peripheral vein by the anesthesiologist. Ultrasound guidance is used to drive the dissection plane as previously described. Reference standards are histology and imaging at 6 months after surgery. Univariate and multivariate analyses are performed. Statistical significance is set at P=0.05.

    Also called Sonovue, Sonazoid, CEIOUS

    After entering the abdominal cavity, liver mobilization is achieved by dissecting the round and falciform ligaments. IOUS is carried out with a standard 3-6 MHz convex probe, and a 7.5-10 MHz micro convex probe. Staging was completed by CE-IOUS using the standard 3-6 MHz convex probe and the dedicated 1.88-3.76 MHz harmonic frequency probe. In all patients, 2.4 mL of sulphur-hexafluoride microbubbles (SonoVue®, Bracco, Milan, Italy) are injected through a peripheral vein by the anesthesiologist.

Questions about this trial

What is this clinical trial studying?

An observational study of Colon Cancer Liver Metastasis, run by University of Milan at 1 site in Italy.

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 2 inclusion and 1 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: finished, as of the sponsor's last update on 3 Feb 2012. 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 Italy. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

new colorectal liver metastases detected at contrast-enhanced intraoperative ultrasonography (time frame: October 2007 - March 2011 (up to 4 years)). 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 3 Feb 2012.
