Temporal trends in non-small cell lung cancer survival in Sweden.
We modeled temporal trends in the 1- and 5-year survival of 32 499 patients with adenocarcinoma and squamous cell carcinoma of the lung in the Swedish Cancer Register between 1961 and 2000. The 1-year relative survival for adenocarcinoma improved from 37% for patients diagnosed 1961-1965 to 45% for those diagnosed 1996-2000 and from 39 to 45% for squamous cell carcinoma. The adjusted excess mortality ratios for the period 1996-2000 compared with 1961-1965 were 0.80 for adenocarcinoma and 0.81 for squamous cell carcinoma. Thus, a previous report in a Dutch study of a relatively worsening prognosis for adenocarcinoma over time could not be confirmed.
