title: [Prognosis of patients after resection for lung cancer with intrapulmonary metastasis in different lobes].
abstract: BACKGROUND
  The prognosis of lung cancer patients with intrapulmonary metastasis in different lobes (pm2) is poor. However, some patients achieve long-term survival. We retrospectively investigated the prognosis of resected primary lung cancer patients with pm2.
  
  
  METHODS
  Among 845 patients with primary lung cancer who underwent complete resection from 1984 to 2003, 14 cases that had lung cancer with pm2 were evaluated about prognostic factors.
  
  
  RESULTS
  The overall 5-year survival rate was 9.5%. The analysis of survival curve based on clinicopathological factors (surgical procedure, histology, tumor size, lymph nodal metastasis, pleural invasion, pleural dissemination and number of pm2) revealed that bronchioloalveolar carcinoma (BAC), the absence of pleural invasion and the absence of pleural dissemination are better prognostic factors.
  
  
  CONCLUSIONS
  Lung cancer patients with pm2 whose lesions show BAC histology, the absence of pleural invasion or pleural dissemination may achieve long-term survival and could be candidates for surgical treatment.
