System to be installed in Rio de Janeiro next year
RIO DE JANEIRO,  December 18, 2012  /PRNewswire/ -- An advanced radiotherapy
treatment system, fully equipped for treating cancer with advanced, image-guided
radiotherapy and radiosurgery, has been ordered by Clínicas Oncológicas
Integradas (GRUPO COI) for installation at the group's Botafogo site in  Rio de
Janeiro.  The TrueBeam system, which was designed to treat tumors with great
accuracy and speed, is the first to be ordered by a treatment center in  South
America, and is slated to be installed by the end of 2013 pending final
approvals by the relevant regulatory agencies in  Brazil.



"This system will enable us to treat cancer using high-quality radiotherapy and
even radiosurgery procedures that are delivered more quickly and more precisely
than is possible now," said Dr.  Monica Schaum, Medical Vice President at GRUPO
COI.  "TrueBeam technology is especially suited for treating tumors that are
close to or embedded in critical organs, such as cancers of the lung, liver,
prostate, or spinal cord, where minimizing the exposure of surrounding healthy
tissues is so important.  With a TrueBeam system, we'll be able to use higher
energy beams along with real-time image guidance for highly precise and targeted
cancer treatments."   

The TrueBeam system, which is made by Varian Medical Systems (NYSE:VAR),
delivers powerful cancer treatments with pinpoint accuracy and precision. It
integrates imaging and motion management technologies, making it possible to
monitor and compensate for tumor motion during treatment.   

Benefits of the System  

"With this system, we'll be able to treat patients who wouldn't have other
options," said Dr. Schaum.  "For example, we are sometimes asked to use advanced
modalities like IMRT and stereotactic radiosurgery to help patients who have
relapsed after earlier courses of radiotherapy delivered using older technology.
 With the level of precision that TrueBeam affords, we can consider performing
re-irradiations in some of these cases, because the technology will help us do a
better job of minimizing the impact on surrounding healthy tissues that already
received some dose and may be approaching their maximum tolerance."  

TrueBeam can be used for radiotherapy treatments including image-guided
radiotherapy and radiosurgery (IGRT and IGRS), intensity-modulated radiotherapy
(IMRT), RapidArc radiotherapy, and stereotactic body radiotherapy (SBRT).   

RapidArc Radiotherapy at GRUPO COI Treatment Centers

Once the new TrueBeam is installed, the Botafogo treatment center will become
the second GRUPO COI site to offer RapidArc radiotherapy, which is an efficient
image-guided method for delivering precise treatments that conform to the
three-dimensional shape of the tumor.  RapidArc is delivered at the group's
Barra Medical Center using a Trilogy radiotherapy system from Varian.

"Our clinical team has treated over 200 cancer patients using RapidArc
radiotherapy since we acquired the capability at the Barra site," said  Helio
Salmon, head of the Medical Physics Department at GRUPO COI.  "We have also
gained experience there treating lung and liver cancer with SBRT, which involves
attacking tumors very precisely with carefully-shaped, high dose X-ray beams. 
We fully anticipate expanding our RapidArc and SBRT programs once the new
TrueBeam system is operational.  It will enable us to utilize these advanced
approaches for treating even many types of cancer with speed and precision."

Doctors at GRUPO COI expect to be able to treat up to 50 patients per day using
the new TrueBeam system once it is installed.   

"The TrueBeam system is Varian's most advanced offering for image-guided cancer
treatments," said  Milton Munhoz, National Sales Manager for Varian in Brazil. 
"We are honored to work with  GRUPO COI, which is very much on the leading edge
of cancer care, having adopted modern technologies for the benefit of cancer
patients in  Brazil."
