title: Prognostic factors in elderly patients with advanced non-small cell lung cancer treated with first-line cisplatin-based chemotherapy: a retrospective analysis of single institution.
abstract: OBJECTIVE
  Non-small cell lung cancer (NSCLC) makes up 80-85% of all lung cancers cases. Lung cancer in older individuals is frequently undertreated. Patients eligible for cisplatin- based chemotherapy should be selected carefully. The aim of this retrospective single-center study was to evaluate prognostic factors for overall survival (OS) in elderly (≥65 years) patients with advanced NSCLC who received first-line cisplatin-based chemotherapy.
  
  
  METHODS
  We retrospectively reviewed 110 elderly patients with locally advanced or metastatic NSCLC who had been administered cisplatin-based first-line chemotherapy between December 2004 and November 2011. Seventeen potential prognostic variables were chosen for analysis. Univariate and multivariate analyses were conducted to identify prognostic factors associated with OS.
  
  
  RESULTS
  Among the 17 variables of univariate analysis, 4 were identified to have prognostic significance for OS: comorbidities (p<0.001), Eastern Cooperative Oncology Group (ECOG) performance status (PS) (p=0.02), first-line chemotherapy cycles (p<0.001) and serum albumin level (p=0.04). Multivariate analysis showed that only ECOG PS (p=0.01) was independent prognostic factor for OS.
  
  
  CONCLUSIONS
  PS was important prognostic factor in elderly patients with advanced NSCLC. The findings of this study may facilitate pretreatment prediction of OS and therefore can be used for selecting the most appropriate treatment for elderly patients.
