Science DiscussionsWright added, “Despite the availability of good factual information for patients, GPs still play a central role in the provision of information to at-risk ageing men about the high-technology tests and treatment options that many will inevitably face.” [AMA] ARTICLE TWO The second MJA article is entitled “Prostate cancer and prostate-specific antigen testing in New South Wales.” Its authors are David P Smith, Rajah Supramaniam, Villis R Marshall, and Bruce K Armstrong. This article discusses prostate-specific antigen (PSA) testing in New South Wales, along with the incidence and mortality of prostate cancer in NSW. The researchers used data from PSA testing undertaken between 1989 and 2006, and statistics from prostate cancer cases and deaths from 1972 to 2005, both in New South Wales. The study found that the PSA tests conducted from 1994 to 2006 more than doubled in numbers. In addition, the incidence of prostate cancer reached its maximum level in 1994, dropped by approximately 10% for each of the next four years. Then, between 2001 and 2005, the incidence of prostate cancer increased by about 4.9% each year. The abstract to their paper states, “An estimated 19,602 (43%) more men than expected from preceding trends were diagnosed with prostate cancer between 1989 and 2005 after PSA testing was introduced.” The authors added, “The incidence of recorded advanced prostate cancer at diagnosis fell from 13.0 per 100,000 men in 1987–1991 to 7.0 per 100,000 men in 2002–2005. The age-standardised mortality from prostate cancer increased by 3.6% per year between 1984 and 1990 and then fell by 2.0% per year to 2005.” What did Dr. David Smith, the lead researcher of the study state?
