Popis: Background Long-term survival of patients with non-small cell lung cancer (NSCLC) is considerably higher in Norway compared to Denmark, even though diagnostic work-up, treatment, and follow-up are comparable. We aim to explore factors behind favorable long-term survival for lung cancer patients in Norway compared to Denmark.Method A retrospective cohort study of patients with NSCLC diagnosed between 2014 and 2016. From the Danish Lung Cancer Registry, 1000 patients were randomly selected, and 974 patients were included. From the Norwegian Vestfold Hospital Trust, 220 patients were randomly selected, and 218 were included. Data from medical records were obtained for all patients. The Danish and Norwegian cohorts were compared using the Pearson chi squared test and multivariate logistic regression analysis.Results The two cohorts were comparable in terms of age, sex, and smoking history. However, the Danish patients had a higher number of pack-years (43.5 vs 34.5 p
