Background: Lung cancer is the leading cause of cancer death worldwide. Clinically appropriate cancer-directed surgery is an influential and significant prognostic factor. In a population-based study, we determined how urban/rural residence was related to surgery receipt for patients with non-small cell lung cancer. We assessed the relationship between relative survival and patients' area of residence, taking into account surgery receipt and area socioeconomic level. Methods: We extracted data from the National Cancer Registry Ireland on patients with non-small cell lung cancer diagnosed during 1994–2011 and linked to area-level data on socioeconomic indicators and urban/rural categories. We calculated ORs for receipt of cancer-directed surgery using logistic regression with postestimation of adjusted proportions. Relative survival estimates with follow-up to 31 December 2012 were calculated for all cases and stratified by surgery receipt, adjusting for clinical variables, area socioeconomic level and other sociodemographic characteristics. Results: 15 031 people diagnosed with non-small cell lung cancer were included in the analysis. On the basis of the multiple logistic regression model, a significantly larger proportion of urban patients (adjusted proportion 23%) as compared with rural patients (adjusted proportion 21%) received surgery (p<0.001). In multivariate analysis, rural residence was significantly related to a decrease in excess mortality for all cases (HR 0.90, 95% CI 0.87 to 0.94, p<0.001) and for non-surgical cases (HR 0.88, 95% CI 0.85 to 0.92, p<0.001). Conclusions: The findings point to the need for targeted policies addressing access to treatment for rural patients with non-small cell lung cancer.
