肺癌X 线普查的普及使早期肺癌得以发现。但临床上常见的肺癌多半仍属Ⅲ期、Ⅳ期,进展期肺癌的治疗仍有重要意义。近年来随着图象诊断技术的显著进展,已能明确判明肺癌浸润邻近脏器的范围,加之人工脏器材料的开发,使肺癌连同周围脏器广泛切除已成为可能,已有对进展期肺癌连同浸润的胸壁、纵隔脏器、心包、膈肌、大血管及部分食道一并切除,并做纵隔淋巴结清扫成功的报告。另一方面,近年来随着高龄肺癌患者的增加,以肺叶以下为切除单位的保存机能的缩小手术亦应运而生。兹总结报告如下: The popularity of X-ray screening for lung cancer has made early-stage lung cancer discoverable. However, clinically common lung cancer is still mostly in stage III and IV. The treatment of advanced stage lung cancer still has important significance. In recent years, with the remarkable progress in image diagnosis technology, it has become clear that the scope of infiltration of adjacent organs by lung cancer, combined with the development of artificial organ materials, makes it possible to perform extensive resection of lung cancer together with surrounding organs, and it has become possible for advanced lung cancer. Together with the infiltrating chest wall, mediastinal viscera, pericardium, diaphragm, large vessels, and some esophagus, a report of successful mediastinal lymph node dissection was performed. On the other hand, in recent years, with the increase in elderly patients with lung cancer, the reduction of the preservation function using the lobe below the resection unit has also emerged. The summary report is as follows:
