title: [Assessment of surgery for stage IV non-small cell lung cancer].
abstract: We assessed the survival of surgery for stage IV non-small cell lung cancer. Forty-two patients were operated on lung cancer for stage IV from 1986 to 2005. Overall median survival time (MST) was 12.3 months and 5-year survival rate was 9.8%. There was significant difference in survival between pulmonary metastasis (pm2) and other sites metastasis (p<0.05). In pm2 patients there was significant difference between ipsilateral metastasis and contralateral metastasis (MST 21.9 months, 2-year survival rate 48.6%, 5-year survival rate 21.6% and MST 12.3 months, 2-year survival rate 0%) [p<0.05], and between complete resection and incomplete resection (MST 36 months, 2-year survival rate 64.8%, 5-year survival rate 28.8% and MST 12.3 months, 2-year survival rate 0%) [p<0.01]. In patients with brain metastasis, surgery of brain metastasis was better prognosis than radiation therapy (MST 12.5 months, 3-year survival rate 33.3% and MST 8.3 months, 2-year survival rate 0%) [NS].
