Lung Cancer at St. Anthony’s Hospital 2000-2009 with Comparisons with the National Cancer Data Base Lung cancer is the second most common cancer seen at St. Anthony’s (SAH) and accounted for 16% of analytic cases in 2009. Nationally lung cancer accounted for 14.8% of all cases. The incidence of this disease has been stable over the last ten years as noted in figure 1.
Stage distribution and comparisons are as noted. Patient with lung cancer are rarely diagnosed in early stages and for NSCL only 24% were stage I/II and for SCL only 13%. See figures 5 and 6 Figure 5
The frequency of smoking has been declining for many years and SAH became a completely smoke free campus in 2010. We looked to see if the percent of lung cancer patients identified as smokers has changed over the last ten years and if this affected their prognosis.
Smoking Distribution by Gender and Histology During the period 2000-2005 16% of the NSCL patients were non-smokers and this number increased to 19% in 2009. With SCL 6% were non-smokers during 2000-2005 and this number rose to 21% in 2009. The details by gender and histology are as noted in figure 9. Figure 9 17% 4% 12% 9% Female 4% 2% 7% 7% Male Non-smoker 33% 44% 43% 41% Female 46% 50% 39% 43% Male Smoker 2009 2000-05 2009 2000-05 SCL NSCL
The outcome for non-smokers was superior to smokers. The 5 year relative survival for NSCL rose from 10.4% (smokers) to 16.3% (non-smokers). For SCL patients the survival was also much better, 5.13% (smokers) and 37.2% (non-smokers), see figure 10. Figure 10
