Prostate cancer survival rates improved since introduction of PSA testing
Date:8/22/2012

Philadelphia, PA, August 23, 2012 The routine use of prostate specific antigen (PSA) testing for screening and monitoring prostate cancer has led to early and more sensitive detection of the disease. A new study published in The Journal of Urology reports that in the "PSA era," survival has improved for patients with newly diagnosed prostate cancer that has spread to the bones or other parts of the body and the disparity between African American and Caucasian men has been resolved.

"Our analysis indicates an overall improvement in risk adjusted survival rates for non-African American and African American men. Of note is the resolution of disparity in survival between the races found in earlier studies," says lead investigator Ian M. Thompson, Jr., MD, Director of the Cancer Therapy and Research Center, a National Cancer Institute-Designated Cancer Center, and Professor in the Department of Urology at the UT Health Science Center at San Antonio, TX.

The Southwest Oncology Group, a National Cancer Institute (NCI) sponsored organization that conducts clinical trials in adult cancers, has performed a series of clinical trials over the last three decades that evaluated patient survival after androgen deprivation treatment (ADT) for prostate cancer. Two of the trials took place before, and one took place after the introduction of PSA screening. "These sequential trials provide an opportunity to address the question of whether survival has improved since the advent of widespread PSA screening and follow-up testing," says Dr. Thompson. Patient populations and eligibility criteria were comparable across the three studies, which enrolled patients from cancer centers around the country. Patients in all three trials received similar ADT treatments.

Median survival in trial S8494, which enrolled patients from 1985 to 1986, was 30 months, and median survival in trial S8894, which enrolled patients from 1989 to 1994, was 33 months.
