Not Applicable
Completed
Conditions
Liver Metastases From Colorectal Primary Cancer
Interventions
Device: Contrast-enhanced intraoperative ultrasound
Registration Number
NCT01880554
Lead Sponsor
Institut Bergonié
Brief Summary

Hypothesis: Use of contrast ultrasound showed interesting results, which can increase ultrasonography sensitivity performed during surgery in the evaluation of operable liver metastases.

This study is a two-stage phase II multicenter study (Simon's two-stage).

  3. Patient treated or not with preoperative chemotherapy.
  4. With or without extra-hepatic metastases
  5. Age ≥ 18 years.
  6. Radiological assessment by CT and MRI liver and positron emission tomography scan (PETscan) within six weeks before surgery.
  7. Patient affiliated to the Social Security system.
  8. Signed informed consent.
Exclusion Criteria
  1. Known hypersensitivity to sulfur hexafluoride or another component of SonoVue®.
  2. Patients with recent acute coronary syndrome or suffering from unstable ischemic heart disease, especially: evolving myocardial infarction, unstable angina during the last 7 days, recent coronary intervention or another factor suggesting clinical instability, acute heart failure, class III or IV heart failure, severe arrhythmias.
  3. Patients with right-to-left shunt, severe pulmonary arterial hypertension, uncontrolled systemic hypertension, as patients suffering from respiratory distress syndrome.
  4. Pregnant and lactating women.
  5. Patients with contraindication for a CT scan, a MRI or a positron emission tomography (PET) with contrast.
  6. Patients with indication of two step liver surgery.
  7. Patients already included in the study.
  8. Patient who couldn't be treated or followed up according to study criteria for psychological, social, family or geographical reasons. Patient deprived of liberty or under guardianship.

Primary Outcome Measures
NameTimeMethod
Clinical Utility of Intraoperative Contrast Ultrasound in the Surgery of Colorectal Cancer Liver Metastases.At time of surgery

The clinical utility will be evaluated in terms of justified modification of the surgical procedure following contrast-enhanced intra-operative ultrasound (CE-IOUS), compared to the surgical procedure following conventional intra-operative ultrasound. For each patient, we will consider CE-IOUS to be clinically useful:

* if the surgical procedure envisaged at the end of the CE-IOUS is different from the surgical procedure envisaged at the end of the conventional ultrasound

* and if the surgical procedure envisaged at the end of the CE-IOUS is justified We reported the percentage of patients for whom there was a modified and justified surgical gesture following CE-IOUS.

Secondary Outcome Measures
NameTimeMethod
Clinical Utility of CE-IOUS in Subgroup of Patients Who Received Preoperative Chemotherapyat time of surgery

The primary endpoint will be assessed in the subgroup of patients who received preoperative chemotherapy. As for the primary outcome, the clinical utility is evaluated in terms of justified modification of the surgical gesture envisaged following CE-IOUS, compared to the surgical gesture envisaged following a conventional intraoperative ultrasound.

We reported the percentage of patients for whom there was a modified and justified surgical gesture following CE-IOUS in the subgroup of patients who received preoperative chemotherapy.

Performance Evaluation of Intraoperative Ultrasound Contrast: Detection Rate Per Lesionup to 3 months after surgery

Detection of malignant lesions by CE-IOUS in chemotherapy-free patients within 3 post-operative months. The detection rate is defined as the proportion of malignant lesions for which there is concordance between the diagnosis established by CE-IOUS and the reference examination.

Description of Technical Arrangements for the CE-IOUSAt time of contrast-enhanced IOUS

Description of technical arrangements for the CE-IOUS duration. The length of time during which contrast injection was useable.

Performance Evaluation of Intraoperative Ultrasound Contrast Per Lesion: Characterisation Rateup to 3 months after surgery

Characterisation rate for focal liver lesions: the proportion of lesions whose nature on CE-IOUS is identical to the nature of the lesions defined by the reference examinations among all the lesions seen on CE-IOUS (malignant and benign)
