New data support watchful waiting for prostate cancer

  • Posted: August 14, 2013

Prostate cancer aggressiveness may be established when the tumor is formed and not alter with time, according to a study published in Cancer Research, a journal of the American Association for Cancer Research. Researchers from the Harvard Medical School and Brigham and Women's Hospital (components of the Dana-Farber Cancer Institute) found that after the introduction of widespread prostate-specific antigen (PSA) screening, the proportion of patients diagnosed with advanced-stage cancers dropped by more than six-fold in 22 years, but the proportion diagnosed with high Gleason grade cancers did not change substantially. This suggests that low-grade prostate cancers do not progress to higher grade over time.
