本文作者报告 Veterans Administra-tion 外科组根治性切除的肺癌患者2349例。其中单纯手术切除组为1176例,手术加化疗组1173例。肺癌的年龄分布,在淋巴结转移组和非转移组,最高峰均在60～69岁组,单纯手术组的5年及10年生存率分别为26.2%和16.3%,手术加化疗组的5年及10年生存率分别为24.8%和13.5%,两组生存率间无显著差异。淋巴结是否存在转移对预后有着重要的意义,
The authors report 2349 lung cancer patients who underwent radical resection in the Veterans Administra-tion surgery group. Among them, 1176 cases were treated with surgery alone, and 1173 cases were treated with surgery plus chemotherapy. The age distribution of lung cancer was highest in the lymph node metastasis group and the non-metastatic group. The 5-year and 10-year survival rates of the surgery-only group were 26.2% and 16.3%, respectively. The 10-year survival rate was 24.8% and 13.5%, respectively. There was no significant difference between the two groups in survival rates. The presence or absence of lymph node metastasis has important implications for prognosis.
