No results posted yet for this study

Summary

This study will see whether collecting and analyzing needle biopsy samples from cancer liver metastases after a tumor 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.

Conditions

  • Liver Metastases

Interventions

DIAGNOSTIC_TEST

[18-F]- FDG - PET

Patients will undergo a limited non-contrast CT and first injection PET to localize the lesion

PROCEDURE

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