and smoking statistics (all at CCG level) were used. We estimated the number of LCs in each CCG that would be eligible for screening and then applied a shift in stage at diagnosis from the current level to a new MLHC CCG- equivalent level. This cohort of LC patients, with new stage data, were then re-introduced to the rest of the LC patients not in the screening program. Finally, an estimate is made for the additional number of patients surviving for at least 1 and 5 years 4 . To show the impact upon health services for both the no- NSP and NSP scenarios, stage1 LC treatment rates (SABR, RT, Surgery and no treatment) were applied at CCG level using English treatment rates (12%) 3 . This was repeated using Dutch rates(41%) 3 . Results Stage1 patient numbers could increase by 115% if a NSP was successfully implemented. This is an increase of ≈450 RT, ≈950 SABR and ≈4,000 surgical patients (Table 1a). 1 year survival would increase from 41% to 53%. 5 year survival would increase from 16% to 26% (Table 1b&c). If England treated with the same rates as the Dutch then SABR patient numbers could increase by ≈2,000 patients (Figure 1) with RT and surgical numbers decreasing. If both a NSP and improvements to access occurred then it could result in an extra ≈5,200 SABR patients, ≈130 RT patients and ≈2,400 surgical patients per year.
Conclusion Survival rates for LC in England are lower than some parts of Europe. This could be addressed by increasing access to the latest treatments and by improving early diagnosis. However, a health service has to be prepared for both situations before successful implementation. Here we have calculated the potential increase in stage1 patient numbers and the service consequences. References 1. Crosbie PA, et al. Thorax 2019. Doi:10.1136/thoraxjnl- 2017-211377 2.

The questionnaire was modelled after the published 2017 workforce/equipment survey of 2016 data (Loewen et al. Int J Radiat Oncol Biol Phys 2019;105(1):42-51), re-analyzed here for all centres in common, to permit trend analysis. utilization in Canada. Material and Methods
