AB  - BACKGROUND: Early-onset prostate cancer is often more aggressive and may have a
      different aetiology than later-onset prostate cancer, but has been relatively
      little studied to date. We evaluated occupation in relation to early- and
      later-onset prostate cancer in a large pooled study. METHODS: We used
      occupational information from census data in five Nordic countries from 1960 to
      1990. We identified prostate cancer cases diagnosed from 1961 to 2005 by linkage 
      of census information to national cancer registries and calculated standardised
      incidence ratios (SIRs) separately for men aged 30-49 and those aged 50 or older.
      We also conducted separate analyses by period of follow-up, 1961-1985 and
      1986-2005, corresponding to pre- and post-prostate-specific antigen (PSA)
      screening. RESULTS: For early-onset prostate cancer (n = 1521), we observed the
      highest SIRs for public safety workers (e.g. firefighters) (SIR = 1.71, 95%
      confidence interval [CI]: 1.23-2.31) and military personnel (SIR = 1.97, 95% CI: 
      1.31-2.85). These SIRs were significantly higher than the SIRs for later-onset
      disease (for public safety workers, SIR = 1.10, 95% CI: 1.07-1.14 and for
      military personnel, SIR = 1.09, 95% CI: 1.05-1.13; pheterogeneity = 0.005 and
      0.002, respectively). Administrators and technical workers also demonstrated
      significantly increased risks for early-onset prostate cancer, but the SIRs did
      not differ from those of later-onset disease (pheterogeneity >0.05). While our
      early-onset finding for public safety workers was restricted to the post-PSA
      period, that for military personnel was restricted to the pre-PSA period.
      CONCLUSION: Our results suggest that occupational exposures, particularly for
      military personnel, may be associated with early-onset prostate cancer. Further
      evaluation is needed to explain these findings.
