Brief Summary:
This study will see whether collecting and analyzing needle biopsy samples from colon cancer liver metastases (CLM) after a thermal ablation procedure will be able to identify cancer cells that are still alive. The results of these biopsies could help determine the next treatment for your cancer, but the biopsies could cause side effects.

Estimated Study Completion Date : October 2024

Arm Intervention/treatment
Experimental: Patients with Colon Cancer Liver Metastases
The standard of care thermal ablation procedure, post-ablation biopsies and pre- and post-ablation PET scans. If the PET scan is positive (shows areas of cancer in the treated metastases), study participants will undergo additional needle biopsies of the positive areas on the scan. If the biopsies show areas of cancer cells that are still alive, the participants will be immediately retreated with a second ablation procedure.
Diagnostic Test: [18-F]- FDG - PET
Patients will undergo a limited non-contrast CT and first injection PET to localize the lesion

Procedure: Thermal ablation (TA)
Standard ablation with the intent to create a radius of ablation at least 10 mm larger than the largest lesion diameter in order to achieve a minimum of 5 mm ablation margin around the tumor. Any radiographically-identified and biopsy-confirmed residual tumor will be treated on site with immediate ablation. This repeat ablation is not standard of care but will be performed as described for the initial ablation (in the same procedure session) and follow up will be resumed.

Diagnostic Test: PET/CT Scan
Eligible patients will undergo PET/CT -guided thermal ablation as per standard IR guidelines. All patients will undergo PET/CT again, within approximately 6 weeks (+/- 2 weeks) of thermal ablation to evaluate for CN in the target tumor(s) or any sign of residual tissue enhancement, representing viable residual tumor and incomplete treatment.

Primary Outcome Measures :
  1. Tumor response [ Time Frame: 2 years ]
    will be measured according to RECIST and PERCIST 1.0. The first CT and PET scan taken after ablation will be considered the new baseline for subsequent comparisons and measurements.
