We treated surgically 567 patients with primary lung cancer from June 1975 to December 1989. There were nine patients with advanced (p-stage III.IV) lung cancer less than 2.0 cm in size. The five year survival rate was 50.8%. The histological diagnosis was adenocarcinoma in 6, squamous cell carcinoma in 3. A curative resection was performed in seven of nine patients. Six patients had one level metastasis of mediastinal lymph node. Three patients in whom relative curative resection was performed at surgery later developed regional recurrence. However, distant metastasis was not evident in all but one of nine patients. In conclusion surgical resection is considered to be significant in patients with advanced (p-stage III.IV) lung cancer less than 2.0 cm in size.
1975年6月至1989年12月期间，我们对567例原发性肺癌患者进行了手术治疗。有9例晚期（p分期III、IV期）肺癌患者，肿瘤大小小于2.0厘米。五年生存率为50.8%。组织学诊断为腺癌6例，鳞状细胞癌3例。9例患者中有7例进行了根治性切除。6例患者有纵隔淋巴结一级转移。3例术中进行相对根治性切除的患者后来出现局部复发。然而，9例患者中除1例之外，其他患者均未出现远处转移。总之，对于肿瘤大小小于2.0厘米的晚期（p分期III、IV期）肺癌患者，手术切除被认为具有重要意义。
