Decreasing mortality rates for prostate cancer: possible role of hormonal therapy?

ABSTRACT

Within the last decade prostate cancer mortality rates have started to decrease in some countries. Although it is tempting to assume that these trends are a result of earlier diagnosis and aggressive therapeutic intervention, as a consequence of prostate-specific antigen screening, definitive results from randomized trials of screening will not be available for several years. Moreover, there is mounting evidence that the effects of screening cannot be entirely responsible for this reduction in mortality rates. This review explores the possibility that other factors, particularly the increased uptake of early hormonal therapy, are contributing to the observed changes in mortality.
