Recent trends in resection rates among non-small cell lung cancer patients in England.
BACKGROUND
Lung cancer resection rates are low in England, but reports have indicated an increase in recent years. We analysed the recent trends in surgical resection by age, sex, socioeconomic deprivation and surgical procedure in England.


METHODS
Data on 286 217 patients with non-small cell lung cancer diagnosed between 1998 and 2008 were extracted from the English Cancer Repository Dataset and information on surgical resection for these patients was retrieved from linked Hospital Episode Statistics records. We calculated the OR of undergoing surgery per 1-year increment by age, sex, socioeconomic deprivation and surgical procedure. A multinomial logistic regression model was used to assess the association between age and type of surgery.


RESULTS
The proportion of patients with non-small cell lung cancer undergoing surgery increased from 8.8% in 1998 to 10.6% in 2008. The increase was similar between levels of socioeconomic deprivation, slightly more pronounced among women (OR=1.023 per 1-year calendar increment, 95% CI 1.016 to 1.029) than men (OR=1.010, 95% CI 1.005 to 1.015) and most prominent with increasing age (75-79 age group: OR 1.051, 95% CI 1.041 to 1.062; 80-84 age group: OR 1.102, 95% CI 1.080 to 1.124; and 85+ age group: OR 1.130, 95% CI 1.069 to 1.193). Increasing age was associated with a decreased likelihood of undergoing pneumonectomy (OR 0.88, 95% CI 0.87 to 0.89 per 5-year age increment) or sleeve resection (OR 0.75, 95% CI 0.71 to 0.79) compared with lobectomy, and a slightly increased likelihood of undergoing a wedge resection (OR 1.08, 95% CI 1.06 to 1.10).


CONCLUSIONS
Resection rates have increased in England in recent years and most markedly so in the older age groups.
