Radiation therapy plays a potential curative role in the treatment of patients with non-small-cell lung cancer with locoregional disease who are not surgical candidates and a palliative role for patients with metastatic disease. Stereotactic body radiation therapy is a relatively new technique in patients with early-stage non-small-cell lung cancer. A trial from RTOG(®) reported >97% local control at 3 years. For patients with locally advanced disease, thoracic radiation to a dose of 60 Gy remains the standard of care. Sequential chemotherapy or radiation alone can be used for patients with poor performance status who cannot tolerate more aggressive approaches. Chemotherapy should be used for patients with metastatic disease. Radiation therapy is useful for palliation of symptomatic tumors, and a dose of approximately 30 Gy is commonly used. Endobronchial brachytherapy is useful for patients with symptomatic endobronchial tumors. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.
放射治疗在局部区域疾病的非小细胞肺癌患者中具有潜在的治疗作用,这些患者不适合手术治疗,在转移性疾病患者中具有姑息作用。立体定向体部放射治疗是早期非小细胞肺癌患者的一种相对较新的技术。RTOG(®)的一项试验报告称,3 年时局部控制率>97%。对于局部进展期疾病患者,胸部放疗至 60Gy 仍是标准治疗。对于不能耐受更积极治疗方法的体能状态较差的患者,可以单独使用化疗或放疗。对于转移性疾病患者,应使用化疗。放射治疗对有症状的肿瘤有姑息作用,通常使用约 30Gy 的剂量。对于有症状的支气管内肿瘤,支气管内近距离放射治疗很有用。ACR 适宜性标准是针对特定临床情况的循证指南,由多学科专家小组每两年审查一次。指南的制定和审查包括对同行评议期刊的现有医学文献进行广泛分析,并应用成熟的共识方法(改良 Delphi)对小组进行影像学和治疗程序的适宜性进行评分。在缺乏证据或证据不明确的情况下,可以使用专家意见来推荐影像学或治疗。
