Between 2001 and 2002, 606 men with CaP from Western Australia were qualified to participate in a case-control study. They completed a self-administered questionnaire on personal demographics, family cancer history, screening history and occupational history. A military history was also obtained. The data was compared to case-matched control men obtained from the Electoral Roll.
A family history for CaP had a significant positive association with CaP, increasing the risk 2-fold. A history of military service did not increase the risk of developing CaP, although a specific history of serving in Vietnam did increase the risk but not to a statistically significant level.
This study used a population-based cancer registry and pathologically-confirmed cases of CaP. While an association between service in Vietnam and CaP was found, lack of statistical significance may reflect the low response rate of 64% among eligible cases.
