title: Role of DNA repair gene polymorphisms in the efficiency of platinum-based adjuvant chemotherapy for non-small cell lung cancer.
abstract: BACKGROUND
  Cisplatin-based adjuvant treatment of non-small cell lung cancer (NSCLC) has become standard, thanks to the studies that have shown a significant survival advantage. The identification of patients who could benefit from this adjuvant treatment would allow ineffective and toxic administrations to be avoided. Immunohistochemical expression of the excision repair cross-complementation group (ERCC)-1 protein has been associated with response to platinum-based chemotherapy in patients with NSCLC, and some polymorphisms of the genes involved in DNA repair have been shown to be associated with survival in advanced NSCLC.
  
  
  OBJECTIVE
  The aim of our study was to evaluate the progression-free survival and tolerability of adjuvant treatment with platinum-based chemotherapy in patients with NSCLC, according to common DNA repair gene polymorphisms and ERCC1 expression.
  
  
  METHODS
  We investigated the association of three DNA repair gene polymorphisms - Asn118Asn in ERCC1 (rs11615), Lys751Gln in ERCC2 (rs13181), and Asp1104His in ERCC5 (rs17655) - with the progression-free survival of 85 patients treated with platinum-based chemotherapy after surgery for NSCLC.
  
  
  RESULTS
  We did not find significant associations between any of these polymorphisms and progression-free survival, nor did we observe any difference in progression-free survival according to ERCC1 expression.
  
  
  CONCLUSIONS
  The previously reported impact of DNA repair gene polymorphisms on platinum-based chemotherapy treatment of advanced NSCLC was not observed in our study in the adjuvant setting.
