Introduction Liverpool is an area of high socioeconomic deprivation, with more than twice the national incidence of lung cancer. In order to benchmark our survival performance at the Liverpool Lung Cancer Unit (diagnosing about 400 new cases/year) we wanted to compare our Units performance against national figures (32% 1 year survival, and 10% 5 year survival). We were also interested in determining if our survival rates had changed over time. Methods We conducted a retrospective analysis of data for all patients diagnosed over a period of 9 years. All analyses were conducted on the entire dataset stratified on the basis of 3 years’ time intervals (2007–2009; 2010–2012; 2013–2015). Demographic data were analysed and compared using descriptive statistics. Survival analysis was conducted by Kaplan Meier survival plots and log- Rank tests. P-values less than 5% were considered statistically significant. Results 3710 patients were diagnosed, with a mean age of 71.3, 52.5% male. Performance state (PS) 0=15%, 1=29.4%, 2=22.2%, 3=19.8%, 4=6.4%. Stage at diagnosis 1=19.7%, 2=6.6%, 3=23.3%, 4=41.3%. There was no significant change in numbers, age, PS, histological subtypes and stage over the 3 time periods. However, a survival rate of 40% and 16% was observed for 1 year and 5 years respectively, which is higher than the national average (figure 1). In addition, there was an increase in survival for patients diagnosed in latter time period compared with the earlier time periods. Interestingly, only stage IV patients showed significant improvement in survival for 2013–2015(p Conclusions Survival rates for our unit are higher than the national average. An increase in oncological treatments for stage IV patients appears to have contributed to the significant improvement in survival for these patients. |
