New Possibilities for Patients With Difficult to Treat Cancers

First UK Novalis TxTM Radiosurgery Launched Today

LIVERPOOL, England, February 7, 2011 - Today, for the first time in the UK, cancer patients are starting to
receive treatment with Novalis Tx radiosurgery. This device gives the chance
of a cure to those with inoperable tumours and offers the possibility to
perform precise painless treatment to tumours in a single patient visit.

The Novalis Tx makes it possible for doctors to treat patients with
tumours virtually anywhere in the body in just a single session. Combining a
'sat nav' like targeting system and powerful treatment beams, the Novalis Tx
can destroy cancerous cells and helps to protect surrounding healthy tissue.
Treatment is also made more patient-friendly by delivering frameless
radiosurgery for brain tumours; an alternative to techniques that require
immobilisation with an invasive head ring[1] that is affixed to the skull.

In its first year of operation the Novalis Tx, installed at the brand new
Clatterbridge Cancer Centre - Liverpool, is expected to treat over 800 cancer
patients. It is estimated that 150 of these patients will be priority brain
tumour patients where precise, non-invasive treatment is particularly
effective.

Dr Brian Haylock, Consultant Oncologist and Clinical Director for
Radiotherapy at Clatterbridge Centre for Oncology, comments:

"Unlike some other highly specialised radiation treatment machines, the
Novalis Tx can treat many different types of cancer in all over the body
allowing us to treat more cancer patients with a single device. This coupled
with the speed with which we can treat patients - in some cases in as little
as 15 minutes in just one session - means the equipment will be available for
the benefit of more patients here in the UK."

The Novalis Tx promises to improve patients' access to world-leading
cancer treatment in the UK. Clatterbridge and The Walton Centre have worked
in partnership to bring this state-of-the-art treatment option to UK
patients. Later this year Novalis Tx machines will become operational at two
other specialist NHS cancer centres in Edinburgh and Manchester. Treatment
with Novalis Tx will be considered for any patient in the UK for whom their
doctor feels it is suitable.

Almost 300,000 people are diagnosed with cancer in the UK each year[2]
and recent estimates show that of these almost 50,000 people develop either
primary or secondary brain tumours[3]. Malignant primary brain tumours take
more years off the average person's life than any other cancer and are the
most significant cause of cancer death amongst men under 45 years and women
under 352.

Sue Farrington-Smith, Director of the charity Brain Tumour Research,
comments on the launch:

"We are delighted that advanced brain tumour treatments like the Novalis
Tx are now available to cancer patients on the NHS. The work of Clatterbridge
and The Walton Centre Trusts in Liverpool will undoubtedly provide the best
cancer care for their patients. This is inspirational stuff."

Clatterbridge Centre for Oncology's new purpose-built facility will be
equipped with the Novalis Tx radiosurgery system and two other radiotherapy
treatment systems, together with expert cancer rehabilitation and support
services.

David Brett, Marketing Director for Radiotherapy at Brainlab, the
radiosurgery pioneers who co-developed the Novalis Tx with medical device
manufacturer Varian Medical Systems, said:

"We continually strive to develop cutting-edge treatments that offer
doctors the best treatment possibilities for their patients. We are proud to
be part of the collaboration between leading oncology and neurosurgery teams
and delighted to offer better care to UK patients. We hope that the three
first sites for the Novalis Tx will help support the provision of improved
cancer care to patients."
