Hoag Memorial Hospital Presbyterian became the only hospital in Orange
County, and one of the first in the nation, to provide oncologists with
the technology to pinpoint tumors during radiation treatment – even
in some of the most difficult-to-target areas in the body, including the
pancreas, lungs and other soft tissue tumors. Hoag will be utilizing this
new treatment as part of its recent opening of a unique cell therapy trial
for pancreatic tumors.
The real-time images provided by the ViewRay MRIdian™ help the dedicated
radiation oncology team at Hoag Family Cancer Institute keep a radiation
beam directly on target throughout every treatment, allowing for a degree
of precision and monitoring capabilities that were not previously possible.
The technology, known as the MRIdian linear accelerator, combines a high-strength
magnetic resonance imaging (MRI) machine and a linear accelerator into
a single device. The MRI machine provides high-quality, real-time images
of tumors to more precisely destroy them with radiation beams from the
linear accelerator.
The results are improved outcomes and decreased side effects associated
with radiation therapy treatments. The adaptive planning and real-time
imaging capabilities enable Hoag’s radiation oncologists and physicists
to respond to any unexpected changes before or even during treatment.
This is particularly helpful with tumors that move as a patient breathes.
“Our bodies move constantly. Our lungs move as we breath, our diaphragms
contract and relax. And any tumor or adjacent organ shifts accordingly,”
said Craig Cox, M.D., medical director of Hoag Radiation Oncology. “With
real-time MRI-guided therapy, we now can hit a moving target with exact
precision. We can see the target, we can see the critical normal tissue
we want to avoid, and we make adjustments to the treatment plan while
the patient is being treated.”
For example, if a patient’s tumor were to shift due to breath or
internal organ movement, the machine would stop the delivery of radiation
and allow physicians to adjust their approach in real time. It’s
a next-level technology that is safer, more adaptable and more effective
in providing targeted radiation treatment, Dr. Cox said.
Ranked in the top 10 percent in the nation, Hoag’s cancer survival
rates continually exceed national averages, illustrating the strength
and effectiveness of its multidisciplinary tumor-specific programs. Hoag
Radiation Oncology is the highest volume program in Orange County and
among the strongest in Southern California. Hoag’s Radiation Oncology
team consists of five dedicated radiation oncologists, with the recent
recruitment of Shane Lloyd, M.D., Ph.D. from the University of California,
San Francisco, five dedicated physicists, dosimetrists, radiation therapists
and radiation oncology trained nurses. Together, this team provides the
most advanced approach to radiation oncology in Orange County between
Hoag’s two comprehensive cancer centers in Newport Beach and Irvine.
“The addition of the MRIdian linear accelerator is yet another example
of how Hoag is committed to delivering the most advanced, most effective
cancer care to our Orange County community,” said Burton Eisenberg,
M.D., Executive Medical Director, Hoag Family Cancer Institute and the
Grace E. Hoag Executive Medical Director Endowed Chair. “Through
philanthropic support and visionary leadership from Hoag’s world-renowned
oncology physician team, Hoag continues to be on the forefront of technology
and cancer therapy.”
Famed author Dean Koontz and his wife, Gerda, donated $9 million to support
Hoag’s technological advancements. The purchase of the MRIdian linear
accelerator was made possible by their generosity, and in honor of the
philanthropic couple’s support, Hoag renamed its radiation oncology
center in Newport Beach the Dean & Gerda Koontz Radiation Oncology Center.
Dr. Cox expressed his gratitude to the couple for helping Hoag lead the
charge in changing cancer care.
“At Hoag, we are fortunate to have the community support that allows
us to be early adopters, not just of the latest technology, but of technology
that is changing how we approach cancer care,” Dr. Cox said.
