Brief Summary:

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.

PURPOSE: This research trial is studying matrix metalloproteinases after surgery or radiofrequency ablation in patients with liver metastases from colorectal cancer.

Condition or disease Intervention/treatment
Colorectal Cancer Metastatic Cancer Other: laboratory biomarker analysis Procedure: cryosurgery Procedure: radiofrequency ablation Procedure: therapeutic conventional surgery

Detailed Description:



  • Describe the kinetics of postoperative changes of serum matrix metalloproteinases (MMP) (MMP-1, MMP-2, MMP-7, MMP-9) and their inhibitors (TIMP) (TIMP-1, TIMP-2) as a function of surgical technique.


  • Determine the predictive value of postoperative risk of recurrence.
  • Correlate the risk of recurrence with surgical technique.
  • Determine whether elevated serum levels of MMP are a better marker than the carcinoembryonic antigen of hepatic or extrahepatic recurrence.
  • Determine whether the postoperative serum of HGF/SF is correlated to changes in plasma levels of MMPs.

OUTLINE: Blood samples are collected periodically before and after treatment to analyze for metalloproteinases and their inhibitors.

After completion of study treatment, patients are followed at day 45 and then every 3 months for 2 years.
