Lung tumor radiofrequency ablation: where do we stand?

摘要: Today, radiofrequency ablation (RFA) of primary and metastatic lung tumor is increasingly used. Because RFA most often used with curative intent, preablation workup must be a preoperative workup. General anesthesia provides higher feasibility than conscious sedation. The electrode positioning performed under computed tomography for sake accuracy. delivery adapted to location, different impedances when treating tumors or without pleural contact. estimated rate incomplete local treatment at 18 months was 7% (95% confidence interval, 3–14) per tumor, depicted 4 (n = 1), 6 2), 9 12 2). Overall survival disease-free were, respectively, 71 34%. Size key point selection because large size predictive poor survival. ratio volume relative complete ablation. Follow-up that relies on the zone demonstrates presence Positron emission might an interesting option. Chest tube placement pneumothorax reported in 8 12%. Alveolar hemorrhage postprocedure hemoptysis occurred approximately 10% procedures rarely required specific treatment. Death mostly related single-lung patients hilar tumors. No modification forced expiratory first second between pre- post-RFA 2 found. high efficacy rate. use as palliative tool combination chemotherapy remains explored.
