title: Clinical trials in advanced stage lung cancer: a survey of patients' opinion about their treatment.
abstract: BACKGROUND
  The major aim of this study was to investigate what patients with advanced stage lung cancer, enrolled in a clinical trial, thought about their treatment. We also wanted to investigate if there exist any characteristics that could influence patients' opinion about the clinical trial.
  
  
  METHODS
  Over the period from June 2008 to June 2009, 59 eligible patients were enrolled in this study. The major inclusion criteria were: participation in a clinical trial, previously treated advanced stage lung cancer, and good performance status (ECOG 0-2). All patients were asked to answer a questionnaire designed to investigate their impressions about participation in a clinical trial. The questionnaire was deposited in a sealed box which was opened at the end of the study.We investigated a possible influence of age, gender, education, lung cancer stage, chemotherapy line and tumor type on the patients' opinion about some aspects of the clinical trial.
  
  
  RESULTS
  The majority of the patients were aware they were participating in the clinical trial and a significant number of them were very satisfied with the treatment. Of the investigated factors, only the level of education had a statistically significant influence on some of the questions raised in the questionnaire.
  
  
  CONCLUSIONS
  Patients participating in clinical trials are satisfied with their treatment, ready to proceed with it and would recommend it to other patients. It depends mainly on health professionals to maintain this level of confidence and justify their trust.
