“Radiosurgery” is not Robotic Prostate Surgery – Dr. David Samadi

Dr. David Samadi, a world renowned prostate cancer surgeon and urologist recently explained the difference between Robotic Prostate surgery and

“Radiosurgery”. These are two options that have been particularly confusing for some are seeing both as robotic surgery.

The renowned surgery recommends the use of robotic prostate surgery over non-surgical radiosurgery.

PRNewswire, an online source of prostate cancer information provided details on explanations made by Dr. Samadi. Here are more on the online excerpt:

Not all robots are created equal, particularly when it comes to prostate cancer, says world-renowned prostate cancer surgeon, Dr. David Samadi . Specializing in minimally invasive da Vinci robotic prostatectomy surgery, Dr. Samadi is not only Vice Chairman, Department of Urology at The Mount Sinai Medical Center; he is also Chief of Robotics and Minimally Invasive Surgery.

Robots are employed to treat prostate cancer in two distinct ways, according to Dr. Samadi. Robotic prostatectomy is robot-assisted surgery to remove the cancerous prostate, such as the Samadi Modified Advanced Robotic Technique – SMART Surgery. Radiosurgery, or radiation therapy for prostate cancer, uses a robot to deliver high doses of radiation to the prostate cancer tumor. According to Dr. Samadi, the differences between these treatments are significant.

Prostate cancer “radiosurgery” is not actually surgery.

Radiosurgery technicians use 3D imaging and computerized adjustments to deliver precise, high-dose radiation to the prostate. There is no surgical component to “radiosurgery” and the cancerous prostate is not removed, it is simply targeted, based on secondary imaging and biopsy data, according to Dr. Samadi.

Robotic prostatectomy, in comparison, is also enhanced by 3D visualization and precision enabled by the robot, though to a much different end. During robotic prostatectomy, the cancerous prostate and seminal vesicles are removed in entirety.

“Radiosurgery lacks what I believe to be the most critical aspects of treating prostate cancer: precise diagnosis and definitive recovery,” said Dr. Samadi. “With SMART surgery, I make real-time decisions based on informed firsthand visualization. During surgery, my eye is on the prostate and after surgery that prostate is in the lab. There is no substitute for that level of prostate cancer analysis.”

Prostate cancer post-treatment considerations:

Robotic prostatectomy surgery affords post-surgery tumor analysis to verify prostate cancer type and extent, radiosurgery does not

PSA (prostate-specific antigen) level should drop to undetectable levels after robotic prostatectomy surgery; after radiation PSA level continues to fluctuate

Radiosurgery alters prostate tissue in such a way that a prostate cancer recurrence is likely to be inoperable

Most SMART surgery patients regain sexual potency in 12-24 months and urinary control in 2-3 months

“Patients who lead with robotic prostatectomy over non-surgical radiosurgery are better positioned for complete prostate cancer removal and optimal recovery,” says Dr. Samadi, who encourages patients to reserve radiation or radiosurgery for advanced prostate cancer or salvage treatments.

The decision to have surgery should never be taken lightly and to those patients debating the merits of noninvasive verses minimally invasive prostate cancer treatment Dr. Samadi adds, “Prostate cancer is invasive. Robotic prostatectomy is a highly successful and minimally invasive way to remove the cancer and arrest further invasion.” Source.

Conclusively, from the explanations of Dr Samadi, it can easily be concluded that there is difference between “robotic prostate surgery” and “radiosurgery”. The doctor has highlighted the advantages the robotic surgical approach has over the non-surgical “radiosurgery” option.

From the facts above, it becomes readily easy to choose robotic prostatectomy. This is because it readily becomes successful and it is also a minimally invasive procedure when removing prostate cancer from the body.
