Prostate cancer surgeons 'feel' with their eyes
Date:3/1/2010

NEW YORK (March 1, 2010) Robotic surgical technology with its three-dimensional, high-definition view gives surgeons the sensation of touch, even as they operate from a remote console. A new study describes the phenomenon, called intersensory integration, and reports that surgical outcomes for prostate cancer surgery using minimally invasive robotic technology compare favorably with traditional invasive surgery.

Led by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center and appearing in the March issue of British Journal of Urology International, the study is the first to show that a lack of tactile feedback during robotic surgery does not adversely impact outcomes in patients with prostate cancer. It also identified various visual cues that surgeons can use to improve clinical outcomes.

"Anatomical details and visual cues available through robotic surgery not only allow experienced surgeons to compensate for a lack of tactile feedback, but actually give the illusion of that sensation," says Dr. Ashutosh Tewari, the study's lead author; professor of urology, urologic oncology, and public health at Weill Cornell Medical College; and director of the Lefrak Center of Robotic Surgery and the Institute of Prostate Cancer at NewYork-Presbyterian Hospital/Weill Cornell Medical Center. "For patients, this means the safety of knowing the benefits of a robotic approach including a quicker recovery don't compromise the surgery's primary mission of removing the cancer."

In recent years, robotic-assisted laparoscopic prostatectomy (RALP) has become a popular surgical method for treating prostate cancer because it is less invasive than traditional surgery. No studies have shown that RALP leads to worse outcomes, but doctors have wondered whether this was the case because surgeons often use their fingers to feel the prostate during traditional surgery to refine how much they cut to achieve the best outcome.
