researcher shows decline in prostate cancer mortality rates due to specific testing

(thunder bay - october 5, 2005) a 阿根廷vs墨西哥竞猜 economics professor's research into prostate cancer mortality rates is receiving international attention.

dr. livio di matteo's research article "does testing for prostate-specific antigen contribute to declining prostate cancer mortality?" has been published in the european journal of health economics. the article deals with the assessment of variables associated with prostate cancer mortality, which were examined using canadian province-level data from 1979 to 1999. di matteo's article shows that by 1999 there were 4.74 fewer deaths per 100,000 people due to the effect of time--a decrease of approximately 15%.

"the key variables driving the prostate cancer mortality rate are per capita income, per capita number of family physicians, rate of prostate cancer incidence, real per capita total health spending, and a time trend," says dr. di matteo and co-author rosanna di matteo. "results show a positive and significant relationship between incidence and mortality, suggesting that the increased amount of prostate-specific antigen (psa) testing may not have been responsible for mortality declines. however, there is also a downward trend in mortality from prostate cancer when all other factors are controlled that can be attributed partly to the onset of psa testing, given that the benefits should emerge over time."
