Thermal ablative techniques produce irreversible tumor tissue destruction throughapplication of either hot or cold thermal energy.At now pulmonary ablation of primary lung cancer should be reserved for patients who arenot candidates for curative surgical resection as a result of cardiorespiratory comorbidity orinsufficient vital lung function.The maximum number of lung metastases that may be ablated is still not clearly definedMost centers preferentially treats patients with five or fewer pulmonary metastases.Combining ablation and surgery for treatment of a larger number of lesions in bilateralmetastatic tumors may be a useful option for improving the chance of a cure and limiting diseaseinvasiveness.The use of percutaneous RFA combined with systemic chemotherapy may offer improvedsurvival in patients with non resectable colorectal pulmonary metastases.
