ELEKTA VMAT RADIATION THERAPY RAPIDLY GAINING USERS
WORLDWIDE AS TECHNIQUE EVOLVES

Elekta calls next generation Elekta Volumetric Modulated Arc Therapy (VMAT) “the
definitive arc
-
based technique.”



ATLANTA, Feb. 12 /PRNewswire/


Entering its third year
of commercial
availability,
Elekta VMAT

has garnered more than 200 orders, with many customers
using the arc
-
based technique clinically since 2008. The
se clinical Elekta VMAT
users have employed the method to treat hundreds of patients worldwide. With Elekta
VMAT, single or multiple radiation beams sweep in uninterrupted arc(s) around the
patient, reducing treatment times from the eight to 12 minutes req
uired for standard
radiation therapy to as few as two minutes.



“As a pioneer in arc
-
based radiation treatment, we are gratified to see the clinical and
practical benefits of Elekta VMAT afforded to many hundreds of patients around the
world,” says Dee M
athieson, Senior Vice President, Oncology Business Line
Management. “The current integration of the technique with an
electronic medical
record

[EMR]

system and introduction of an improved VMAT planning package on
the horizon make Elekta VMAT a comprehensive treatment solution and the
definitive arc
-
based technique on the market.”



The 2009 meeting of the
American Society for Radiation Oncology

(ASTRO)
featured numerous posters and presentations on Elekta VMAT studies. Summaries of
selected studies:






Casa di Cura S. Chiara, Firenze, Italy: VMA
T v. IMRT plan comparisons for prostate
cancer. Result: Retrospective VMAT plans would provide shorter treatment times and
lower radiation dose (fewer MU’s).




University Medical Center Mannheim, Germany: IMRT v. VMAT in treatment of
spinal metasta
ses. Result: IMRT is superior to 3D conformal in target coverage, but
had treatment times averaging 10 minutes. VMAT also provided an excellent dose
distribution, but recorded treatment times of less than four minutes and lower dose
(fewer MU’s) compared t
o IMRT.




William Beaumont Hospital, Royal Oak, Michigan: VMAT for stereotactic body
radiation therapy (SBRT) of lung and spine. Results: In two lung cases, VMAT
reduced dose enough to enable SBRT. In three spine cases, radiation dose was
reduced versus IM
RT. Treatment times were decreased by up to 13 minutes or 59
percent.



At the University of Tokyo, clinicians led by Keiichi Nakagawa, M.D., radiation
oncologist and professor in the department of radiology, have treated more than 60
prostate cancer pati
ents with Elekta VMAT. The entire treatment takes just 10
minutes, encompassing patient room entry, imaging of the patient on the table to
adjust treatment positioning, 100 seconds of VMAT beam
-
on
-
time and patient room
exit.



Clinicians at University Med
ical Center Mannheim have been evaluating Elekta
VMAT for a year, utilizing the technique for 15 patients with prostate or paraspinal
tumors. This work confirmed for Mannheim doctors the ability of the Elekta treatment
and control systems to deliver the ra
diation arcs rapidly and as specified in plans.



Patients with tumors in regions that are affected by motion, such as those in the lungs
and prostate could benefit substantially from Elekta VMAT’s speed, according to
Frank Lohr, M.D., vice chair, departm
ent of radiation oncology at Mannheim. It also
is beneficial for patients whose pain makes prolonged treatment sessions undesirable.



“For patients with bone metastases, for example, it will be a lot easier for them to
tolerate a one to two minute Elekta
VMAT treatment compared to the current five to
seven minute treatment per session,” he notes.



In the design of Elekta VMAT, Elekta has integrated the latest version of its digital
control system, which facilitates clinical use of VMAT while emphasizing o
ptimal
patient safety.
