Abstract
OBJECTIVE: To monitor incidence and mortality rates of prostate cancer in the province of Quebec. DESIGN: Population-based incidence and mortality trends. SETTING: Entire population of the province of Quebec between 1979 and 1996. MAIN OUTCOME MEASURES: Age-standardized incidence rates and mortality for prostate cancer. RESULTS: Prostate cancer mortality increased regularly until 1989, were stable between 1989 and 1995 and dropped in 1996 by 15%. Incidence rates increased steadily from 1989 until 1993 by an average of 9% per year. CONCLUSION: The rise in incidence is due to the increasing use of prostate specific antigen as a screening test for prostate cancer. The reasons for the reduction in prostate cancer mortality are unknown but are likely to reflect improved treatment modalities.
