The Prostate Cancer Cohort Study includes nearly 1000 incident cases of prostate cancer who were diagnosed between 1997-2000 in Alberta and were part of a population-based case-control study that we conducted here. The cases were initially interviewed for the case-control study at the time of their diagnosis and then re-interviewed approximately two years after diagnosis. They were also asked to complete self-administered questionnaires on their physical activity and quality of life every two years for another two follow-ups. We completed the follow-up and obtained data on any progressions, recurrences and deaths that have occurred in this cohort of prostate cancer cases and are undertaking analyses of these data at present.
