OBJECTIVE: To describe and interpret changes in incidence, mortality and survival of lung cancer in the Netherlands in the period 1989-1997. DESIGN: Secondary data analysis. METHODS: Data on the incidence of lung cancer were collected from the Dutch Cancer Registration (1989-1997), on mortality from Statistics Netherlands (CBS; 1989-1994), on the incidence of lung cancer in other European countries from EUROCIM (1990-1994), on survival of Dutch lung cancer patients from the Comprehensive Cancer Centre Amsterdam (1988-1997) and the Comprehensive Cancer Centre South (1988-1992) and on survival of other European lung cancer patients from EUROCARE (1985-1989). Incidence rates were calculated per 100,000 person years and standardized by age according to the European population structure. Survival was calculated as the ratio of observed survival among the lung cancer patients and the expected survival of the general population. RESULTS: The incidence of lung cancer among men decreased from 109 to 93, whereas that among women increased from 18 to 23. The incidence of lung cancer among Dutch men was high in comparison to other European countries, whereas that among women was average. The trends in lung cancer incidence were probably related to the trends in past smoking behaviour. Mortality decreased among men from 106 to 91 and increased among women from 15 to 20. Survival was better for younger patients, a localised tumour, and better for squamous cell carcinoma or adenocarcinoma than for large-cell undifferentiated or small-cell carcinoma. The relative 5-year survival was 12%, the relative 1-year survival 39%; these were good in comparison with other European countries. CONCLUSION: The incidence and mortality of lung cancer among Dutch men decreased, but still in 1997 almost 20 men in the Netherlands died each day of lung cancer. Among women the end of the increase is not in sight and in 1997 over 5 women died each day of lung cancer.
