    MONTREAL, Sept. 2 /CNW Telbec/ - In operation since recently at the
Centre hospitalier de l'Université de Montréal (CHUM), the CyberKnife(R)
Robotic Radiosurgery System, is revolutionizing the treatment of both
cancerous and non-cancerous tumors anywhere in the body. Used in radiation
oncology, the CyberKnife System is the latest word in radiosurgery technology.
Designed to destroy tumours using radiation beams, it is the first system of
its kind to treat tumors non-invasively to be installed in Canada. It provides
a pain-free, non-surgical option for patients who have inoperable or
surgically complex tumors, or who may be looking for an alternative to
    Though its name may conjure images of scalpels and surgery, the
CyberKnife treatment involves no cutting. Accuray's CyberKnife System uses
stereotactic radiotherapy(*) to treat tumours. One of the most remarkable
aspects of the CyberKnife is its ability to track tumour movement as the
patient breathes. Its unequalled precision means that the CyberKnife does not
require the use of rigid head-frames that are screwed into the patient' skull
to minimize any movement, such as in the case of brain tumour treatment. The
CyberKnife uses two x-ray cameras installed on the ceiling for continuous
image guidance.
    "With precision that enables high doses of radiation to be channelled to
a hair's-breadth, the CyberKnife reduces the time of treatment needed in most
cases," adds Dr. Jean-Paul Bahary, chief of the Radio-oncology Department of
the CHUM, and associate professor, Université de Montréal.
    The CHUM will use the CyberKnife mainly in the treatment of intracranial
tumours, spinal tumours, certain types of lung, urological, gastrointestinal,
and otorhinolaryngological cancers, and for research.

    (*) Stereotactic radiotherapy

    Stereotactic radiotherapy consists of administering fractionated,
ultra-thin beams of high dose radiation that converge on the target, with
minimal harm to critical structures around the tumour.

    The CHUM Radio-oncology Department

    One of the units treating the highest number of patients in Canada, the
CHUM's Radio-oncology Department is also among the foremost academic centres
in North America in terms of the number of clinical trials led by the American
College of Radiology's Radiation Therapy Oncology Group - a further
demonstration of the CHUM and the Department's role of leader in research and
