Colon Cancer Clinical Trial
Tissue Analysis After Thermal Ablation for Colon Cancer Liver Metastases Leading to Immediate Retreatment
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.
Diagnosis of colorectal cancer liver metastases (CLM)
Confined liver disease or limited extrahepatic disease stable/controlled for at least 4 months (extrahepatic disease amenable to treatment is allowed)
Lesions of ≤3 cm in maximum diameter
At least one FDG-avid lesion to be treated***
Any patient with CLM treated with Microwave ablation (as per clinical IR Guidelines)*
INR < 1.5*
Platelet count ≥ 50,000
Age < 18
Less than 5 mm distance to a structure (GI or biliary tract), that cannot be protected from ablation injury with technical modifications such as hydro or air dissection
INR > 1.5 that cannot be corrected with fresh frozen plasma **
Platelet count of <50,000 that cannot be corrected with transfusion
More than 3 tumors in the liver
More than 5 tumors of extrahepatic disease (including mediastinal nodes and pulmonary nodules, abdominal or other lymph nodes, and bone metastasis)
Presence of any peritoneal Carcinomatosis
Institutional IR guidelines:
For patients on Coumadin, general clinical guidelines for IR ablation will be followed.
For patients with no FDG-PET avid tumors aim 2 of the protocol will not be assessed
