North Shore Radiation Therapy Offers Prostate Cancer Patients The Latest Tool For Precise Treatment
HUNTINGTON, N.Y. - (Business Wire) Technology to deliver high dose radiotherapy for cancer treatment has constantly been improving and physicians in continue to be faced with the difficulty of treating a moving target. Sophisticated techniques such as intensity modulated radiation therapy (IMRT) have been developed to produce highly conformal beams to minimize dose to healthy tissues. However, without accounting for organ motion, the benefits of these technologies cannot be realized. Radiation Oncologists at North Shore Radiation Therapy in New York are able to account for this motion.
The introduction of image guided radiation therapy, or IGRT, has revolutionized the delivery of modern day radiotherapy for prostate cancer. IGRT combines imaging with treatment delivery to provide up to real-time of the patient's organs in the treatment position, at the time of treatment, optimizing accuracy and precision. Organs including, but not limited to the lung, prostate and bladder tend to move as much as centimeters during the course of treatment and image guidance allows the physician to target and track tumors with pinpoint precision.
There are several techniques used to achieve image guided radiation therapy for prostate cancer. For some tumors, gold markers can be placed in the tumor. The patient is imaged daily prior to each radiation treatment. This is called on board imaging, or OBI. Patients who prefer not to have markers placed can be treated with other image guided techniques such as cone beam CT scan or ultrasound. In cone beam CT, the imager is rotated around the patient to quickly acquire a high-quality, low dose 3-D image of the tumor and surrounding anatomy. These 3-D images are compared to reference images from the treatment plan. Through 3-D image matching, which can be accomplished manually or automatically, shifts are calculated and the patient is moved into position for treatment. This technique is particularly useful for treatment sites that are far away from bony landmarks.
With the third technique, an ultrasound is performed daily prior to each treatment. The images are compared with reference images and the patient is shifted accordingly.
“Image guided radiation therapy allows physicians to treat with pinpoint accuracy diseases including brain tumors, prostate cancer, esophageal cancer, gastric cancer and spine tumors, as well as many others” stated Dr. Heather Zinkin, a board certified Radiation Oncologist at North Shore Radiation Therapy.
Their facilities house state of the art technology and patients can be treated using on board imaging, cone beam CT and ultrasound for high precision therapy.

Prostate IGRT Radiation Treatment
A new technology at North Shore Radiation Therapy enables physicians to precisely adjust for daily variations in the position of a tumor before treating it with high doses of radiation.The medical community has a new way to offer patients prostate cancer treatment. This new technology, Image-Guided Radiation Therapy (IGRT), helps to pinpoint the treatment position for radiation therapy and correct for daily changes in tumor location due to set-up uncertainties, weight, and organ movement.
This technology, which is embedded in a linear accelerator, a device that delivers radiation therapy, allows Radiation Oncologists on Long Island to generate real-time CT images of the patient's anatomy directly from the treatment machine. Within seconds, calculations determine if an adjustment is needed to align the tumor perfectly within the radiation beam. Any corrections, which may be as tiny as 1 to 2 millimeters, are automatically made by adjusting the position of the patient before treatment.
Unlike conventional radiation therapy, the real-time imaging used in IGRT allows each radiation therapy treatment to be delivered to its intended site with pinpoint accuracy, sparing healthy surrounding tissue without significantly increasing the total dose to the patient.
This technology collects treatment data and helps report the effectiveness og treatment. This allows your Radiation Oncologist to further refine treatment techniques to adapt to changs that may occur during your treatment course at North Shore Radiation Therapy.
Through it's precision targeting, IGRT can mitigate many of the side effects caused by radiation therapy, such as dry mouth, weight loss, dry skin, fatigue, nausea and bowel dysfunction.
If you would like to receive a consultation by one of our Board Certified, American College of Radiation Oncology physicians, please call us at (631) 427-2273. This treatment is offered in both our Smithtown and Greenlawn Centers on Long Island in New York.
