title: Population-based trends in use of surgery for non-small cell lung cancer in a UK region, 1995-2006.
abstract: OBJECTIVE
  To assess time trends in use of surgery in patients with non-small cell lung cancer (NSCLC) in a UK region.
  
  
  METHODS
  Cancer registration data for patients diagnosed with NSCLC between 1995 and 2006 in the East of England were analysed. Rates of surgery use for different age, gender, diagnosis period, tumour subtype and deprivation quintile groups were examined.
  
  
  RESULTS
  The analysis included 18,767 patients with NSCLC. During the study period, 13% of patients were treated by surgery. Use of surgery decreased over time from 15% in 1995-1997 to 11% in 2004-2006 (p=0.022). Initial socioeconomic differences in surgery use narrowed significantly over time (p=0.028) and became non-apparent at the end of the study period.
  
  
  CONCLUSIONS
  Use of surgery in patients with NSCLC decreased during the study period, possibly reflecting increasing quality of preoperative staging processes. Initial socioeconomic inequalities in surgery use became undetectable at the end of the study period. The findings provide baseline information to support comparisons with patterns of clinical management in more recent years.
