Overview

At CyberKnife of Long Island, our team has been providing care in the community for nearly two decades. We are experts in CyberKnife® treatment, which is a highly precise and painless alternative to surgery and traditional radiation therapy. CyberKnife can be used to treat prostate cancer, lung cancer, liver cancer, pancreatic cancer, spinal tumors and brain tumors, as well as trigeminal neuralgia and arteriovenous malformations. 

There is no need to wait weeks or even months for an appointment or to begin treatment. Call us today and we can get you in for a consultation as quickly as the next business day. 

Our state-of-the art technology

We are the first cancer center in Suffolk County Long Island to use the CyberKnife® Robotic Radiosurgery System and we have been treating patients with this technology since 2008. Our radiation oncologists have years of experience and hold additional certification in the use of CyberKnife.

CyberKnife is a robotic radiation delivery system that attacks tumors or lesions with high doses of radiation from virtually any direction or angle with sub-millimeter accuracy. CyberKnife stereotactic radiosurgery does not surgically remove the tumor or lesions, but instead, uses high doses of focused radiation to destroy tumor cells. 

CyberKnife continuously and automatically tracks the tumor and your position, including movement that occurs due to breathing. This information guides and positions radiation beams to precisely target the tumor while carefully sparing the surrounding healthy tissue.

Radiation can then be targeted with pinpoint accuracy from virtually any direction or angle. CyberKnife treatments require no recovery time and have fewer complications than traditional surgery. You can go home or back to normal activities the very same day. Treatment is usually completed in under a week (one to five office visits), depending on your specific situation.

The CyberKnife system is based on external beam radiation technology that has been time-tested and used for decades and is well proven to be effective. There have been many clinical studies with the CyberKnife published in medical journals and thousands of patients have received CyberKnife treatment worldwide.

Our practice

Our two Suffolk County Long Island office locations are accredited by the American College of Radiology (ACR). The ACR’s Radiation Oncology Accreditation Program provides radiation oncologists with third-party, impartial peer reviews and evaluations of patient care.

As part of the Northwell Health Cancer Institute, one of the largest cancer programs in the New York metropolitan area, the team works with a wide range of cancer specialists (nearly 200 members in more than 25 different specialties). Patients also have access to a robust research and clinical trials program and an array of cancer support services.

Our Huntington and Smithtown Long Island offices are also a part of the Northwell Health Department of Radiation Medicine. As one of the most innovative radiation medicine groups in the area, the Department of Radiation Medicine provides a wide range of services to adult and pediatric patients, uses state-of-the-art technology, and ensures quality care through evidence-based treatment and one-of-a-kind patient safety programs.

Conditions we treat

CyberKnife can be used to treat a number of conditions, including:

Prostate cancer

CyberKnife’s sophisticated software and respiratory tracking system allows us to confirm the exact location of the prostate tumor and continually track its movement in real time, so we can deliver radiation without damaging healthy tissue in the rectum and bladder. Our CyberKnife experts can help you fight your prostate cancer with low risk of incontinence or impotence and no cutting, pain or long recovery times. Learn more about CyberKnife treatment for prostate cancer here.

Lung cancer

If you have lung cancer and are unwilling or unable to undergo surgery, CyberKnife treatment may be an option to consider. CyberKnife can be used instead of or along with surgery and chemotherapy and is an effective option for recurrent or metastatic cancer. Unlike traditional radiation therapy, CyberKnife precisely identifies the tumor location as the patient breathes normally during treatment. The precision of the CyberKnife allows for a higher dose of radiation per treatment, which reduces the total number of treatments needed. Learn more about CyberKnife treatment for lung cancer here.

Trigeminal neuralgia

CyberKnife is a nonsurgical, noninvasive, painless treatment that delivers high dose radiation to trigeminal nerve roots with extreme accuracy, allowing us to treat them without sacrificing healthy tissue. It is one of the most advanced, precise treatment options available today. Many trigeminal neuralgia patients need only one treatment.

Brain tumors

CyberKnife uniquely benefits patients with brain tumors by eliminating the need for stereotactic frames (stabilizing frames that are put around the patient’s head to limit movement during treatment). As a result, doctors can achieve a high level of accuracy in a non-invasive manner and this allows patients to be treated on an outpatient basis. CyberKnife is either used on a stand-alone basis or in combination with other brain cancer treatments, such as chemotherapy, surgery or whole brain radiation therapy.

Metastatic brain tumors

Metastatic brain disease is a focal disease and local control of the tumor is needed for patient survival. Radiosurgery is an appealing substitute for open surgery in the treatment of brain metastases.  During the CyberKnife treatment, imaging cameras determine the actual location of the tumor. Each time the robotic arm repositions to deliver another treatment, the CyberKnife recalculates the true position of the tumor. The result is unsurpassed, sub-millimeter accuracy. Because CyberKnife does not use an invasive frame, treatment can be delivered over several visits, sparing healthy tissue. 

Liver cancer

Treating liver cancer with radiation therapy is a challenge because liver tumors move with respiration.  In addition, the tissue surrounding a liver tumor is very sensitive and can be damaged easily.  CyberKnife is able to deliver high doses of radiation to both primary and metastatic liver tumors with extreme accuracy. Doctors can zero-in on a moving target - the liver tumor - and irradiate it without harming the healthy surrounding tissue. As a result, the CyberKnife treatment is a comfortable option for patients, radiation is delivered more accurately and treatments can be completed in one to five sessions.

Spinal tumors

Spine tumors present a treatment challenge because they move as the patient breathes. Conventional radiation therapy cannot account for this movement, so surrounding healthy tissue is damaged by the radiation. CyberKnife is able to achieve a high level of accuracy completely non-invasively. It can pinpoint a tumor's exact location in real time throughout treatment. CyberKnife allows the patient to breathe normally while on the treatment table and enables the doctor to zero-in on a moving tumor and focus hundreds of radiation beams from different angles, all of which intersect at the tumor.  Using this method, CyberKnife is able to deliver a high dose of radiation to the tumor while avoiding damage to the surrounding sensitive spinal cord tissue and other critical structures. As a result, radiation is delivered more accurately and treatments can be performed in a shorter period of time.
