Long-term study: Robot-assisted prostate surgery is safe

24.03.2011
In the first study of its kind, urologists and biostatisticians at Henry Ford Hospital have found that robot-assisted surgery to remove cancerous prostate glands is safe over the long term, with a major complication rate of less than one percent.

The findings, published online this month by the journal European Urology, follow an earlier Henry Ford study that found nearly 87 percent of patients whose cancerous prostates were removed by robot-assisted surgery had no recurrence of the disease after five years.

"We have always felt that robotic surgery for prostate cancer was safe, but there have been no studies that have looked at long-term safety. This is why the Henry Ford study is so important," says Mani Menon, M.D., director of Henry Ford's Vattikuti Urology Institute.

The new research analyzed the surgical outcomes of more than 3,000 consecutive patients at Henry Ford's Vattikuti Urology Institute from January 2005 to December 2009, and addressed "the lack of standardized reporting" that hampered previous published literature on complications of radical prostatectomy (RP).

In RP, the entire diseased prostate gland and some surrounding tissue are surgically removed, in hopes of preventing the cancer from spreading to other parts of the body.

Henry Ford Hospital pioneered the use of robots to assist surgeons in the delicate procedure, and the new study notes that robot-assisted radical prostatectomy (RARP) is now the most common technique in the U.S. for treating localized prostate cancer.

The Henry Ford researchers found only one previous report on complications of RP that had adhered to uniform surgical reporting standards. However that study looked at open and laparoscopic prostatectomy, and did not include robot-assisted RP.

Confronted, in a sense, by "apples and oranges" comparisons of several RP surgical techniques, the Henry Ford researchers set out to produce a five-year safety study that both concentrated on RARP and incorporated an exhaustive collection of data, covering everything from length of hospital stay, to an in-depth examination of other diseases afflicting the patients, but unrelated to their cancers.

Among the study group of 3,317 RARP patients, researchers found a median hospitalization time of only one day. There were 368 complications in 326 of the patients – or 9.8 percent of the total – most of which were minor and occurred within 30 days of the surgery.

A patient's prostate-specific antigen (PSA) scores before surgery, as well as cardiac disease, were found to predict medical complications after the robot-assisted surgery; age, gastroesophageal reflux disease (GERD), and biopsy score predicted possible surgical complications.

The researchers' main conclusion was that "RARP is a safe operation."

Henry Ford's robot-assisted urology program uses a surgeon-controlled robot, the da Vinci minimally invasive surgery system.

It enables surgeons to manipulate robotic arms for precise procedures through a series of small incisions, instead of the large wounds required by traditional "open" surgery, and provides 3-D monitoring for the entire surgical team.

The potential benefits for the patient include shorter recovery times, less trauma, and reduced hospitalization costs.

It is also the basis of a "nerve-sparing" procedure called the Veil of Aphrodite, developed at Ford, to minimize the erectile dysfunction common in men after undergoing traditional radical prostatectomy.

"While these results provide strong endorsement for robotic surgery, we want to emphasize that the results are dependent more on the surgical team that controls the da Vinci robot rather than just the robot," Dr. Menon states.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
