title: Prognosis of lung cancer resection in patients with previous extra-respiratory solid malignancies.
abstract: OBJECTIVE
  Non-small-cell lung cancer (NSCLC) following pulmonary or pharyngolaryngeal malignancies has been widely studied, but only a few articles have focussed on lung cancers following other solid malignancies. Our purpose was to compare the characteristics and prognosis of patients with NSCLC according to the medical history of the extra-pulmonary and extra-pharyngolaryngeal solid malignancy.
  
  
  METHODS
  Patients who underwent surgery for NSCLC from January 1980 to December 2009 in two French thoracic centres were reviewed. We compared patients with no history of cancer (Group 1) and patients with a history of extra-pulmonary and extra-pharyngolaryngeal solid malignancy (Group 2).
  
  
  RESULTS
  There were 4992 patients: 4603 (92%) in Group 1 and 389 (8%) in Group 2. In comparison with Group 1, Group 2 showed an increasing incidence over the last 3 decades (2-8%), an older population (65.9 vs 61 years, P < 0.001), a higher proportion of women (34 vs 18%, P < 0.001), non-smokers (20 vs 10%, P < 0.001), adenocarcinomas (53 vs 40%, P < 0.001), T1 (16 vs 14%, P = 0.047) and second nodule in the same lobe (4 vs 2%, P < 0.001). The overall survival was not significantly different between the two groups (P = 0.09). In multivariate analysis, older age, male gender, pneumonectomy, higher T, higher N, incomplete resection and history of extra pulmonary-extra pharyngolaryngeal solid malignancy were significantly associated with a worse prognosis.
  
  
  CONCLUSIONS
  Despite an earlier diagnosis, a history of extra-pulmonary and extra-pharyngolaryngeal solid malignancy is associated with a worse prognosis in patients with NSCLC undergoing surgical resection. Overall survival is particularly low after a history of bladder and upper gastrointestinal malignancies.
