Scrotal cancer: incidence, survival and second primary tumours in the Netherlands since 1989.
BACKGROUND
Since the 1970s there have been few epidemiological studies of scrotal cancer. We report on the descriptive epidemiology of scrotal cancer in the Netherlands.


METHODS
Data on all scrotal cancer patients were obtained from the Netherlands Cancer Registry (NCR) in the period 1989-2006 and age-standardised incidence rates were calculated also according to histology and stage. Relative survival was calculated and multiple primary tumours were studied.


RESULTS
The overall incidence rate varied around 1.5 per 1,000,000 person-years, most frequently being squamous cell carcinoma (27%), basal cell carcinoma (19%) and Bowen's disease (15%). Overall 5-year relative survival was 82%, being 77% and 95% for patients with squamous and basal cell carcinoma, respectively. In all, 18% of the patients were diagnosed with a second primary tumour.


CONCLUSIONS
The incidence rate of scrotal cancer did not decrease, although this was expected; affected patients might benefit from regular checkups for possible new cancers.
