Survival rates and several effective factors for the postoperative course of 10 advanced cases of small sized lung cancer (ASLC) were evaluated. Followings were considered as characteristics of these patients: 1) ASLC were observed at the rate of 4.0% of whole lung cancers, 2) ASLC were more often seen in relatively young patients, females and adeno carcinomas than ordinary lung cancer, 3) as factors concerned to postoperative prognosis, stage III A (especially T1N2M0), few numbers of metastatic lymph nodes in N2, and performance of relative curative operation may predict good prognosis, but adenosquamous type will be a sign of poor prognosis. Satisfactory result was obtained even in a case of stage IV when complete resection of metastasis was carried out. There was no significant difference of survivals between 2 cm and 3 cm of diameter of the tumor. In conclusion, above mentioned points should be considered when operative indication of ASLC is evaluated.
对10例晚期小肺癌（ASLC）患者术后的生存率及多种影响因素进行了评估。这些患者具有以下特征：1）ASLC占全部肺癌的4.0%；2）与普通肺癌相比，ASLC在相对年轻的患者、女性及腺癌患者中更为常见；3）作为与术后预后相关的因素，ⅢA期（尤其是T1N2M0）、N2期转移淋巴结数量少以及实施相对根治性手术可能预示着良好的预后，但腺鳞癌类型将是预后不良的标志。即使在Ⅳ期病例中，若能完全切除转移灶，也可获得满意的结果。肿瘤直径在2cm和3cm之间的患者生存率无显著差异。总之，在评估ASLC的手术指征时应考虑上述要点。
