title: Comparison of liposomal cisplatin versus cisplatin in non-squamous cell non-small-cell lung cancer.
abstract: OBJECTIVE
  Liposomal cisplatin was developed to reduce the systemic toxicity of cisplatin, particularly the nephrotoxicity, and it has been used in combination with other agents in pancreatic and head and neck cancers and non-small-cell lung cancer (NSCLC). Our objective was to compare the effectiveness of lipoplatin combined with paclitaxel versus cisplatin with paclitaxel in advanced non-squamous NSCLC.
  
  
  METHODS
  During 2007-2010, 202 patients with non-squamous NSCLC (stage IIIB and IV) were recruited from the two participating institutions and divided into two arms: Arm A was treated with liposomal cisplatin 200 mg/m(2) combined with paclitaxel 135 mg/m(2) and Arm B with cisplatin 75 mg/m(2) in combination with paclitaxel 135 mg/m(2), repeated every 2 weeks. The number of cycles administered was 632 (Arm A) and 640 (Arm B), totaling 1,272.
  
  
  RESULTS
  A partial response was achieved by 59.22% of Arm A patients versus 42.42% of Arm B, and the difference was statistically significant (P 0.036). The median survival time in months was 10 for Arm A and 8 for Arm B (P 0.1551). After 18 months, the number of surviving patients was double for Arm A versus Arm B.
  
  
  CONCLUSIONS
  Liposomal cisplatin in combination with paclitaxel produces a statistically significantly higher response rate than cisplatin combined with paclitaxel in non-squamous NSCLC.
