Cancer incidence in Gipuzkoa, Spain (1998-2002), and time trends from 1986.
OBJECTIVE
To determine the cancer incidence in Gipuzkoa (Spain) from 1998 to 2002 and describe time trends since 1986.


METHODS
The annual incidence of cancer in Gipuzkoa from 1998 to 2002 was estimated as a rate per 100,000 inhabitants. Incidence trends for the period 1986-2002 were studied for all cancers and for the main cancer sites using Poisson regression and Joinpoint regression for prostate tumours.


RESULTS
On average, one in 3 men and one in 5 women would probably be diagnosed with cancer at some time during their life (0-74 years). Among men, prostate surpassed lung as the most frequent cancer site. Among women, breast cancer represented approximately 30% of all cases of cancer (excluding non-melanoma skin cancers). There was an annual increase in the incidence of cancer of 1.5% (95% CI, 1.1-1.8) in men and 0.9% (95% CI, 0.5-1.3) in women. The incidence of prostate cancer in men increased over the study period, and especially between 1996 and 1999, with an annual increase of 34.7% (95% CI, 5.9-71.5). The incidence of lung cancer in women presented an annual increase of 5.2% (95% CI, 3.4-7.1). In contrast, the incidence of stomach cancer decreased during the study period.


CONCLUSIONS
Cancer incidence in Gipuzkoa increased during the study period. This increase was particularly marked in lung cancer and skin melanoma, for which preventive strategies are fundamental.
