Prostate Cancer Outcomes Study:
History & Goals of the Prostate Cancer Outcomes Study
The Prostate Cancer Outcomes Study (PCOS) was initiated in 1994
by researchers at the National Cancer Institute (NCI) to look
at the impact that treatments for primary prostate cancer have
on the quality of life of men living with prostate cancer. PCOS
is collaborating with six cancer registries that are part of NCI's
SEER Program, established in 1973 to collect cancer
data on a routine basis from designated population-based cancer
registries in various areas of the country.
PCOS is the first population-based evaluation of health-related quality-of-life issues
for prostate cancer patients conducted on a multi-regional
scale. It is expected that better knowledge of the effects of
treatment will help men, their families, and clinicians make more
informed choices about treatment alternatives. PCOS will also
provide the most detailed data ever collected on the patterns
of prostate cancer care.

PCOS data has been used in many publications.
