Saturation Biopsy for Diagnosis and Staging of Prostate Cancer
Prostate cancer is the second leading cause of cancer-related deaths in men in the United States. The diagnosis of prostate cancer is made by biopsy of the prostate gland. At present, many practitioners use a 12 to 14 core “extended” biopsy strategy for individuals undergoing initial biopsy. This extended biopsy is performed in an office setting and allows for more extensive sampling of the lateral peripheral zone; sampling of the lateral horn may increase the cancer detection rate by approximately 25%.
Another approach is the saturation biopsy, in which generally more than 20 cores are taken from the prostate in an effort to improve sampling of the anterior zones of the gland. Saturation biopsy may be performed transrectally or using a transperineal approach.
Saturation biopsy (more than 20 cores) for the diagnosis, staging, and management of prostate cancer is considered investigational.

Studies showing improved initial detection of prostate cancer using saturation biopsy compared with the use of extended biopsies are inconclusive. Few studies show improvement in clinical outcomes with the use of saturation biopsy as part of active surveillance.
