PSA Velocity May be Irrelevant in Detection of Prostate Cancer

Measuring velocity of prostate cancer specific antigen rise over time may not be necessary before deciding whether a man needs a prostate biopsy, according to a large new study from urologists at US and European cancer centers.

 PSA velocity (PSAV) is a term used for change PSA levels in the blood over time. Instead of basing a decision to recommend biopsy (or not) on a single annual PSA reading, the urologist looks at a series of tests and calculates the rate of rise over time.

The new study suggests that calculating PSA velocity does not help to detect prostate cancer once PSA and age are taken into consideration.

This finding was reported by European Association of Urolog this August. “Some guidelines,” Scardino notes, “do incorporate PSAV cut points as an indication for biopsy.”

Two Robots Better Than One for Prostate Surgery

Adding A Second Robot May Help Surgeon to Spare Nerves Controlling Erections

Johns Hopkins researchers have developed a new technique that may improve robotic prostate surgery by using a second robot for taking three-dimensional ultrasound images of the prostate and surrounding structures during the procedure. These images can potentially help surgeons spot the nerve bundle that controls erectile function.
