In May 2002, in cooperation with the Ministère de la Santé et Services sociaux, the Institut national de santé publique du Québec (INSPQ) published survival tables for the four main cancer sites—lung, breast (female), colorectal, and prostate—for cases reported to the Quebec Cancer Registry (QCR) in 1992. These cases were used to calculate the relative survival probability five years after diagnosis.
The study was designed to measure the quality of the incidence and mortality data used to calculate survival probabilities and determine vital status. It has also served to illustrate the decisive impact of data quality on results. Data was also compared with the five year relative survival probabilities in other Canadian provinces despite the fact that Quebec does not establish the date of diagnosis in the same manner and draws its incidence information from a different source.
This report is a continuation of the overall project. Here, survival probabilities have been calculated for all cancer sites reported to the Quebec Cancer Registry between 1984 and 1998, according to cancer site, age, and sex. Pediatric cancers have been analyzed separately. Moreover, survival probabilities have not been calculated exclusively for five year periods as in the previous report, but rather for 1, 3, 5, 8, and 10 year periods (according to availability).
