[Lung cancer mortality in Andalucia, 1975-2000]. / Mortalidad por cáncer de pulmón en Andalucia (1975-2000).

OBJECTIVE: To describe trends in lung cancer mortality in Andalucia, Spain, during the period from 1975 through 2000. SUBJECTS AND METHOD: Records of lung cancer deaths for the period from 1975 through 2000 were obtained from the Statistical Institute of Andalucia. The following indicators were calculated: crude rates, age-adjusted rates, truncated rates, and cumulative rates. RESULTS: Mortality rates for men dropped in all subject groups aged over 50 years during the period from 1994 through 2000. In women mortality rates were much lower, although we observed an increase in the 35-39 and 45-49 age groups, which is reflected in the 6.1% rise in the truncated rates (35-64 years) during the period from 1994 through 2000. In older women mortality rates fluctuated more within the different age groups, although on the whole the truncated rate for all those over 65 years old fell by 9.7% in the period between 1995 and 2000. CONCLUSION: Lung cancer mortality rates among men in Andalusia began to decrease after 1994. In contrast, mortality increased among young women, although their rates are still very low.

Joinpoint regression analysis of lung cancer mortality, Andalusia 1975-2000.

BACKGROUND: Previous analyses of lung cancer mortality were based on models of death rates within one time period, assuming that rates increase or decrease with time at a constant rate. The aim of this work is to analyse recent changes in lung cancer mortality trends in Andalusia (Spain) during the period of 1975-2000 using joinpoint regression models. PATIENTS AND METHODS: Mortality data were obtained from the Death Registry of Andalusia. For each gender, age group-specific and standardised (overall and truncated) rates were calculated by the direct method (using the world standard population). The joinpoint analysis was used to identify the best-fitting points where a statistically significant change in the trend occurred. RESULTS: Lung cancer is the leading cause of cancer mortality in men, with an increasing trend up to 1994. After that year, rates began to decrease significantly (-1.8% yearly from 1994 to 2000). Standardised rates in women exhibited a downward trend until the early 1990s, after which they levelled off (overall standardised rates) or increased significantly (truncated rates 35-64 years). CONCLUSIONS: An increase in lung cancer mortality has been observed in young women. There seems to be a relationship with the prevalence in smoking in men and women.

OBJETIVO: Describir la evolución de la mortalidad por cáncer de pulmón en Andalucía durante el período 19752000. SUJETOS Y MÉTODO: Las defunciones por cáncer de pulmón durante el período 1975-2000 se obtuvieron del Instituto Andaluz de Estadística. Se han calculado los siguientes indicadores: tasas brutas, tasas ajustadas por edad, tasas truncadas y tasas acumuladas. RESULTADOS: En los varones las tasas descienden en todos los grupos de edad por encima de los 50 años durante el período 1994-2000. En las mujeres las tasas son muy inferiores, aunque se aprecia un incremento en los grupos de 35-39 años y de 45-49 años, lo que queda reflejado en un incremento de las tasas truncadas (35-64 años) del 6,1 por ciento en el período 1994-2000. En las mujeres de mayor edad las tasas fluctúan más en los diferentes grupos de edad, aunque en conjunto la tasa truncada (> 65 años) desciende un 9,7 por ciento en el período 1995-2000. CONCLUSIÓN: En Andalucía las tasas de mortalidad por cáncer de pulmón en varones han comenzado a descender desde 1994. Por el contrario, se registra un incremento en las mujeres jóvenes, pero con tasas muy inferiores. (AU)
