Robotic-assisted prostate surgery offers better cancer control, study finds

RATE THIS! +37
Posted in Medicine on 6th Mar, 2014 02:52 AM by AlexMuller

An observational study has found that prostate cancer patients who undergo robotic-assisted prostate surgery have fewer instances of cancer cells at the edge of their surgical specimen and less need for additional cancer treatments like hormone or radiation therapy than patients who have traditional surgery.

 
The study, published online Feb. 19 in the journal European Urology, was led by Dr. Jim Hu, UCLA’s Henry E. Singleton Professor of Urology and director of robotic and minimally invasive surgery in the urology department at the David Geffen School of Medicine at UCLA.
 
Although it is becoming more popular, robotic-assisted radical prostatectomy, the complete removal of the prostate using a robotic apparatus, remains controversial because there has been little evidence that it provides better cancer control than open radical prostatectomy, the traditional surgical approach, which is less costly.
 
In an effort to determine whether or not robotic surgery offered an advantage, Hu and his colleagues compared 5,556 patients who received robotic surgery with 7,878 who underwent open surgery between 2004 and 2009. Data was provided by the Surveillance, Epidemiology, and End Results–Medicare, a program of cancer registries that collect clinical and demographic information on people with cancer.
 
The researchers looked at the surgical margin status of the two groups, which is the amount of cancer cells at the edge of the removed prostate specimen. A positive margin, the presence of cancer cells at the edge, may result from cutting through the cancer and leaving some behind rather than cutting around the cancer completely. In prostate cancer, this has been shown to lead to a greater risk of recurrence and death from the disease.

Robots are used in surgery more and more. They remain, I believe, a more costly option and their performance may not be much better (or just marginally better) - this study shows some benefits that should be taken into consideration

Yes, robotic surgery is more costly. However researchers point out in this study that their findings show that the this particular procedure may translate into less downstream costs and fewer side effects from radiation and hormone therapy

This new study suggests that, although doctors and hospitals are optimistic about robotic techniques, they should carefully evaluate benefits and spend more time producing good evidence Reply

Recently the opposite conclusion was presented form the analysis of colectomies (procedures to remove part of or all of the colon), which can be performed using a minimally-invasive laproscopic technique or using a robot. They found that in this case robotic surgery is no better than the alternative, but it is more expensive

This was not the first time that robotic surgeries faced criticism. The da Vinci system, a multi-armed robot used in thousands of procedures was under investigation by the FDA after reports of mishaps during surgeries. Reply
