Metastatic Colorectal Cancer: Treatment Response With Dynamic Contrast MRI

Terminated

• Conditions: Hepatic Neoplasm; Colorectal Neoplasm
• Interventions: Other: DCE-MRI

• Registration Number: NCT00820456
• Lead Sponsor: American College of Radiology

Brief Summary

The objectives for this study include:

* Testing a unique way of imaging people with colorectal cancer and other cancers that has spread to the liver using magnetic resonance imaging (MRI);

* Seeing if the MRI process can be used across multiple imaging platforms;

* Determining whether the results of the imaging can be reproduced;

* Reviewing how MRI results relate to cancer response to combination therapy and to clinical endpoints.

Detailed Description

This study will investigate the use of projection reconstruction dynamic contrast-enhanced MRI (DCE-MRI) as a surrogate marker of tumor vascularity in patients treated with the antiangiogenic agent bevacizumab. DCE-MRI is gaining popularity as a method to assess the functional response of tumors to agents targeting the vascular endothelial growth factor (VGEF) pathways. DCE-MRI measurements have been proposed as a non-invasive measure of both tumor biologic activity and (in the case of antivascular therapy) early response to treatment. A number of phase I and II studies demonstrate the ability for DCE-MRI to detect perfusion changes associated with tumor biologic response to vascularly targeted agents. It has been suggested that pre-treatment DCE-MRI might identify tumors with high intrinsic perfusion and that these tumors will be more likely to respond to antivascular-based therapies. However, the current use of DCE-MRI in clinical settings is challenging. Trade-offs between spatial coverage, time, and spatial resolution make this technique difficult to implement in human studies and may limit its reliability. The use of projection reconstruction-based acquisition can mitigate the need for these trade-offs and can simultaneously provide high temporal and spatial resolution data for DCE-MRI analysis.

• Participants must not be pregnant or breastfeeding;
• Participants must have prior histological documentation of adenocarcinoma of the colon or rectum;
• Participants must be commencing chemotherapy with FOLFOX plus bevacizumab;

• Participants with prior radiotherapy or other prior local therapy to the liver (radioablation therapy, chemoembolic therapy) are acceptable. They must be at least 4 weeks past the last administration of such therapy;
• Participants must be at least 4 weeks past any major surgery, including surgery to the liver;
• Participants with prior malignancies other than colon cancer are allowed, provided they have been treated with curative intent, and have no evidence of recurrence of that malignancy;
• Participants must have a life expectancy of greater than 3 months;
• Participants must have the ability to understand and the willingness to sign a written informed consent form.

Arm B: Inclusion Criteria

• Participants must be >18 years old;
• Participants must have an ECOG performance status of 0-1;
• Participants must not be pregnant or breastfeeding;
• Participants must have prior histological documentation of any types of cancer with metastasis to the liver (see Imaging Criteria below);
• Participants must be projected to be within a stable treatment condition prior to and between scans (see section 4.3 for definition of stable treatment condition);
• Participants must be at least 4 weeks past any major surgery, including surgery to the liver;
• Participants must have a life expectancy of greater than 3 months;
• Participants must have the ability to understand and the willingness to sign a written informed consent form.

Imaging Criteria:

• Participants must have at least one hepatic lesion greater than or equal to 3 cm in maximal diameter on cross sectional imaging study (CT or MRI) performed within 4 weeks prior to study enrollment;

• Participants must have at least one qualifying liver lesion (i.e. one greater than or equal to 3 cm) that has been confirmed metastatic adenocarcinoma of the colon or rectum based on one of the following criteria:

  • Histologic (FNA or core biopsy) proof of malignancy compatible with metastasis from a colorectal carcinoma; OR

  • Demonstration of imaging features of tumor metastasis to the liver, including at least one of the following:

    1. evidence of heterogeneous enhancement or central tumor necrosis by CT or MRI;
    2. previously demonstrated interval enlargement of the lesion by >25% in the longest diameter;
    3. PET image demonstrating metabolic activity characteristic of malignancy (FDG uptake greater than that of background liver).

• For participants who have undergone local hepatic surgical, radiation, ablative, or embolic therapy, the date of qualifying imaging study(ies) or qualifying biopsy must be at least 30 days after the last instance of such local therapy. Furthermore, cross-sectional imaging performed at least 30 days after such local therapy must demonstrate an area of residual viable tumor (as judged by enhancing tissue following contrast administration) with longest diameter ≥ 3cm in at least one cross-sectional axis.

Arms A and B (Unless Otherwise Indicated):

Exclusion Criteria

• Patients with contraindication to MRI, including:

  1. Contraindicated metallic device, including pacemaker, non-MRI compatible aneurysm clip, other non-MRI compatible mechanical and/or electrical device, or metallic fragments;
  2. Patients with severe claustrophobia (patients with milder forms of claustrophobia that can be successfully allayed with oral anxiolytic therapy are allowed);

• Patients with contraindication to gadolinium, including:

  a) Hypersensitivity to gadolinium-containing MR contrast agents;

• Severe impaired renal function with estimated glomerular filtration rate <30 mL/min/1.73 m2 and/or on dialysis;
