Prostate cancer: 1. The descriptive epidemiology in Canada
| Appendix: Statistical methods |
| Annual age-specific incidence rates for the period 19731993 and mortality rates for 19731996 were calculated for prostate cancer (International Classification of Diseases code 185) for all Canada in 5-year age groups. Data were obtained from the Canadian Cancer Registry (formerly the National Cancer Incidence Reporting System) and the Canadian Mortality Database at Statistics Canada. Population data were obtained from Statistics Canada census publications.
Age-standardized incidence and mortality rates were calculated by the direct method for all Canada and for individual provinces using the 1991 Canadian population as the standard. The probabilities of being diagnosed with or determined to have died from prostate cancer were calculated using standard life-table methods.18,19 The probabilities are based on a hypothetical cohort of 100 000 Canadian men who are subject, during their lifetimes, to current age-specific incidence and mortality rates (1993) and to all-cause mortality risks (19921994). |
