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. ER -
