The usefulness of thoracic irradiation was evaluated in 62 patients with asymptomatic Stage III carcinoma of the lung. In 48 patients, the disease was confined to the thorax, in eight supraclavicular nodes were involved, and in six there were distant metastases. Fourteen patients were in poor general conditions as well. Fourteen patients received a short course of irradiation (less than 3,000 rad [30 Gy]), while 48 received radical doses (5,500-6,000 rad [55-60 Gy]). Five patients (8%), all with carcinoma confined to the thorax, survived three years. Radical radiation therapy plays a positive role in the treatment of asymptomatic State III carcinoma of the lung, and may result in tumor control in those patients with no extrathoracic disease.
对62例无症状的Ⅲ期肺癌患者评估了胸部放疗的有效性。48例患者疾病局限于胸部，8例有锁骨上淋巴结受累，6例有远处转移。另外14例患者一般状况较差。14例患者接受了短疗程放疗（少于3000拉德[30戈瑞]），而48例接受了根治性剂量放疗（5500 - 6000拉德[55 - 60戈瑞]）。5例患者（8%），均为疾病局限于胸部的患者，存活了3年。根治性放疗在无症状Ⅲ期肺癌的治疗中发挥积极作用，对于无胸外疾病的患者可能实现肿瘤控制。
