An inherent limitation of non-surgical therapy is the inability to systematically assess for nodal disease. In one study, among patients with clinical stage I NSCLC, 13.8% of patients were upstaged to N1 disease on final surgical pathology and an additional 3.5% upstaged to N2 disease (28). The presence of nodal or extra-thoracic disease is generally a contraindication to thermal ablation unless the goal of the treatment is palliative. - 知情同意书 3.术前一天准备4. 手术当日病房准备：晨起禁食水5. 手术室准备 |
