"In particular, we could not determine the number of men who would need to undergo a biopsy for an elevated PSA and [be] treated for screen-detected prostate cancer to prevent one case of presenting with metastatic disease. This must be recognized as a limitation of the current study," the researchers said. Likewise, they could not investigate the optimal age to start or to stop screening.
This study was supported by the Ashley Family Foundation. No financial disclosures were reported.
