Cyberknife Arrives at NJ's Overlook Hospital; First in Northeast to Offer New Robotic Technology to Treat Inoperable Brain, Spine Tumors with Incision-Free 'Surgery'

Business Wire, July 20, 2004

SUMMIT, N.J. -- Overlook Hospital, part of New Jersey's Atlantic Health System, is now treating its first patients with the hospital's new $5 million CyberKnife(R). An incision-free "surgical" option, the CyberKnife uses the latest technology to precisely outline malignant or benign tumors and obliterate them with a super targeted beam of radiation.

This virtual surgery transforms the way patients can be treated for cancer and other conditions. There are no incisions, no screws in the skull, no blood, no pain and no anesthesia. In fact, patients usually resume daily activities immediately following outpatient treatment. CyberKnife provides new hope for patients with tumors previously diagnosed as inoperable, and for those who have received the maximum allowable radiation exposure through other treatments.

Overlook Hospital in Summit, NJ is the first in the New York metro area and, in fact, the only hospital north of Baltimore and east of Pittsburgh to offer the CyberKnife(R) Stereotactic Radiosurgery System.

CyberKnife benefits

The CyberKnife treats inoperable tumors in the brain and is the only device cleared by the Food and Drug Administration (FDA) to treat lesions on the spine. The CyberKnife can be used to treat other "hard-to-reach" tumors in the body, such as in the lungs and pancreas, and can treat all areas in the head and neck. Older devices, such as the GammaKnife (which require a head frame), can only reach tumors between the mid-ear and top of the skull. The average CyberKnife treatment is one to five sessions of 45 to 90 minutes each.

The most noticeable benefit to patients is the lack of a head frame during treatments to the brain. All older treatment methods require wearing a metal head frame that gets screwed into the skull.

The CyberKnife sends a precise beam of high dose radiation in a single treatment without damaging surrounding tissue and organs. "A much higher dose of radiation can be sent to destroy the tiniest of tumors," said Louis Schwartz, MD, chair of radiation oncology and co-director of the CyberKnife program at Overlook Hospital. "This also means a tumor next to the nerves that control vision, or next to the brain stem, for example, can now be treated."

How CyberKnife works

The CyberKnife uses the most sophisticated combination of robotics and computer-aided technology available today. It is the same technology used to guide missiles to precise targets, and works similarly to a car's global positioning system (GPS). If the patient moves, the CyberKnife automatically detects and compensates for the change, ensuring the radiation is accurately targeted to the tumor location throughout treatment.

CyberKnife can treat tumors and other lesions through "image-guided radiosurgery." A combination of CT scans, x-rays, highly sophisticated computer software and sensors create an image inside the body to guide the robotic arm that delivers beams of radiation, or radiosurgery to the tumor target. The CyberKnife can strike the tumor with radiation from over 1200 different angles, allowing better coverage of the target than any other radiosurgery system.

New options with CyberKnife

The precision of the CyberKnife and its lack of a head frame means doctors do not need to worry about patient movement and pain during treatment, making CyberKnife a promising option for pediatric patients.

The CyberKnife also provides new options to neurosurgeons. "For the first time, with the pinpoint accuracy of the CyberKnife, we can try to prevent paralysis caused by tumors on the spine," said neurosurgeon Brian Beyerl, MD, co-director of the CyberKnife program. "We can reach abnormal tangles of blood vessels in the brain, that in the past would have been impossible to treat. In addition, the CyberKnife avoids the risks related to surgery including infection, anesthesia, scarring, hair shaving and post-operative bleeding," added Dr. Beyerl.

The future for CyberKnife

Initially, Overlook's CyberKnife team will treat patients with brain and spine tumors. By fall 2004, they will treat tumors elsewhere in the body, such as the lung and pancreas, and other benign disorders in areas such as the pituitary gland and middle ear for acoustic neuromas that cause hearing loss.

The FDA's clearance of the CyberKnife for treating cancer anywhere in the body, and the subsequent coverage by health insurance companies, has made it more attractive for community-based hospitals, such as Overlook, to invest in this technology.

"The CyberKnife will further enhance our state-of-the-art oncology and neuroscience services, adding still another competitive advantage to our hospitals and physicians," said Joseph Trunfio, president and CEO, Atlantic Health System. "The quality of medicine in the suburban setting has been steadily advancing, and with our commitment to the most innovative technology, Overlook is clearly in the forefront of this trend."

CyberKnife at Overlook

The CyberKnife is part of a $35 million investment to expand existing services in Overlook's Cancer Center and Neuroscience Institute, which includes the Stereotactic Radiosurgery Program and Brain Tumor Center of New Jersey, the Columbia Epilepsy Center, neuro-interventional radiology, and the state's first PET/CT scanner.
