A study conducted in Santa Monica, California examined the impact of cryopreserved placental allografts on biochemical recurrence (BCR) in prostate cancer patients. Placental allografts are commonly used to promote wound healing and are placed during radical prostatectomy to improve continence and erectile function recovery. The study included 566 robotic radical prostatectomies and found that cryopreserved amniotic membrane (CAM) allografts did not significantly affect BCR but did improve continence recovery. In vitro analyses also showed that placental allografts reduced prostate cancer cell line growth. This research provides valuable insights into the use of placental allografts in prostate cancer treatment. [Extracted from the article]
