Cancer Center Offers New Radiation Technology

Tue, 05/18/2010 - 6:26am

John Theurer Cancer Center has begun implanting a wireless radiation sensor, so that radiation oncologist can receive immediate data on the amount of radiation being delivered to rumors and surrounding tissue.

John Theurer Cancer Center at Hackensack University Medical Center announces that it is one of two cancer centers in the tri-state area currently implanting a wireless radiation sensor, known as DVS® (Dose Verification System). John Theurer Cancer Center radiation oncologists can now receive data immediately post- treatment on the precise amount of radiation being delivered to tumors and surrounding tissue for prostate cancer treatments.

"Traditional radiation therapies rely on knowing the exact location of the tumor, but provide no guidance on quantifying the actual dose being delivered to the tumor," said Glen Gejerman, M.D., Co-Chief, Urologic Oncology and Director, Radiation Oncology, John Theurer Cancer Center. "With this implantable device, we can now offer critical same day radiation dose adjustments."

The DVS sensors—just 2.1mm in diameter and 20mm long -- are implanted during a minimally invasive procedure and gather data on the precise amount of radiation being delivered to the tumor.  Wireless technology transmits the information to a hand-held monitor and the amount of radiation absorbed is read at the end of each of the daily treatments, enabling doctors to verify that the patient is receiving the prescribed dose.

Deviations in dose delivered to the tumor, or radiation accidentally administered to normal tissue, can have a profound impact on long-term survival rates and quality of life for patients treated with radiation therapy. Accurate delivery of the appropriate dose of radiation is critical to tumor control and cure rate. A long-term clinical study of nearly 230 prostate cancer patients demonstrated statistical significance between dose and benefit, highlighting the importance of measuring the amount of dose delivered.

This is part of John Theurer Cancer Center's ongoing dedication to improving radiation oncology safety and precision through research and adopting the latest technological advancements. John Theurer Cancer Center is the most experienced cancer center in the tri-state area with this implantable device. Dr. Gejerman and his colleagues at John Theurer Cancer Center plan to continue studying the DVS technology to determine the optimal number of sensors to implant and the most favorable locations in the body to implant them. In doing so, they plan to streamline the process of radiation delivery and make it even more precise.
