NWH Northern Westchester Hospital

Radiation Therapy

A convenient distance from both New York City and Connecticut, the Cancer Treatment and Wellness Center at Mt. Kisco’s Northern Westcher Hospital offers painless, highly-effective cancer treatments that destroy the cancer cells' ability to reproduce, and precisely targeting the cancer resulting in minimal side effects and little or no damage to the surrounding tissue. In many cases, radiation can even shrink or destroy a tumor, eliminating the need for surgery. Radiation is administered under the direction of the Radiation Oncologist.
 

External Beam Radiation Therapy (EBRT) and Intensity Modulated Radiation Therapy (IMRT)

External Beam Radiation Therapy delivers high-energy radiation from an external source to the prostate. Since the radiation passes through the skin and organs, it must be given in small doses each day over a period of weeks. Most men can continue normal activities throughout the treatment. The risks include temporary anemia, diarrhea, and fatigue, and rarely, long term injury to nearby organs. Conformal radiation allows higher doses of radiation to be delivered without increased risk. The most advanced method is Intensity Modulated Radiation Therapy (IMRT), which uses a computerized imaging system to limit the amount of radiation to surrounding tissues allowing higher doses of energy to the tumor.  

 

Brachytherapy (BT)

Brachytherapy (BT) involves the implantation of tiny titanium pellets containing a radioactive isotope into the area requiring treatment. The procedure, which involves passing a few needles through the skin, is usually done on an outpatient basis with a recovery time of only a few days. The radiation is released over a period of months.  Higher doses of radiation can be delivered since the radiation does not have to pass through surrounding tissues, as occurs with EBRT.

In some treatments, 5 weeks of EBRT and BT are used together. The EBRT allows treatment of the lymph nodes and areas adjacent to the targeted area, while the BT permits high dose radiation.  Despite the higher overall amount of radiation, the risk of complications is not greater than with either modality alone.

Northern Westchester Hospital provides brachytherapy with or without external radiation. Brachytherapy is performed jointly by the specialist and the Radiation Oncologist to assure the best possible implantation.

 

The Varian Trilogy Linear Accelerator

The Linear Accelerator is the most advanced device of its kind, and offers millimeter-level accuracy and flexible radiation delivery methods that can be programmed to match the type, size, and exact shape of the tumor. Among the treatment options it performs are intensity-modulated radiation therapy (IMRT), image-guided radiation therapy, respiratory gated radiation therapy, 3D-conformal radiation therapy, stereotactic body radiosurgery, and electron beam radiation therapy.

 

Image Guided Radiation Therapy (IGRT)

Radiation oncologists use Image Guided Radiation Therapy, or IGRT, to help better deliver the radiation to the cancer because tumors can move between treatments.  IGRT involves radiation treatment guided by imaging, such as CT, ultrasound or X-rays, taken in the treatment room just before the patient is given the radiation treatment on a daily basis.  All patients first undergo a CT scan as part of the planning process. The information from the CT scan is then transmitted to a computer in the treatment room to allow doctors to compare the earlier image with the images taken just before treatment. This allows doctors to better target the cancer while avoiding nearby healthy tissue. 

 

Intraoperative Radiotherapy (IORT)

The Zeiss Intrabeam intraoperative radiation therapy (IORT) provides precise radiationdose delivery that enables the surgeon to administer the prescribed dose with precision to the tumor site during surgery. 

NWH IORT The Cancer Center uses IORT primarily in breast cancer treatments.  This treatment replaces the "boost" portion of the treatment, eliminating 1 1/2 to 2 weeks from the 6 to 7 week course of radiation needed after lumpectomy.

Yttrium-90

Our experienced team of Radiation Oncologists and Interventional Radiologists performs Yttrium-90 radioembolization to precisely target and radiate hepatocellular cancers of the liver and colorectal cancers without harming healthy tissue. Read more >

 

Chemoembolization

Used most often to treat cancer of the liver, chemoembolization is a combination of chemotherapy and a procedure called embolization. It is a twofold approach to attacking the tumor and limits the body's exposure to the effects of the anti-cancer drugs. Additional information on chemoembolization is available here.

 

Radiofrequency Ablation (RFA)

A minimally invasive treatment used most often to treat liver cancer. Abnormal cells are destroyed using imaging techniques such as Ultrasound and Computed Tomography (CT Scan) and high-frequency electrical currents. You can learn more about RFA and other nonsurgical advances for the treatment of liver cancer in NWH’s Interventional Radiology.

 

Gamma Knife

The Gamma Knife is the most accepted and widely used radiosurgical treatment in the world and delivers a high dose of gamma radiation to the target with surgical precision. Visit the Gamma Knife Center at Northern Westchester Hospital.
