We have studied the alterations in the use of curative treatment and the outcome for lung cancer patients in Norway 2001-2016. The Cancer Registry of Norway has a practically complete registration of all cancer diagnoses, treatments given and deaths. For the years 2001-2016, 43,137 patients were diagnosed with lung cancer. Stereotactic radiotherapy was established nationwide from 2008 and its use has increased, and in 2016, 8.8% were given this treatment. In addition 20.6% were operated and 8.5% were treated with conventional radiotherapy. Thus 37.9% of those diagnosed were treated with intention to cure, compared to 22.9% in 2001 (p < 0.0001). Further, the median survival for the whole group diagnosed with lung cancer increased from 6.0 (95% CI 5.6-6.7) months in 2001 to 11.8 (95% CI 10.9-12.7) in 2016. The 5 year survival increased from 9.4 (95% CI 8.1-10.8)% to 19.9 (95% CI 19.2-20.6)% in the same period. In 2016 the age adjusted incidence rate was 59.5 per 100,000 (Norwegian standard) and had increased significantly in both sexes. There had also been an increase in mean age at diagnosis and the proportion diagnosed in an early stage. The increase in curative treatment has been paralleled with a doubling in both the median and 5-year survival. The present results are used for surveillance and as a benchmark, and we are looking forward to reaching a proportion of 40% of patients given curative treatment.
