Hi,
The below information came from my sister in WA. It is interesting enough
to pass on.

Here is an interesting article dtd 2002 about a High Intensity Focused
Ultrasound therapy used to treat cancer patients. Apparently it has been
used on around 20,000 people in China. (It was developed in the U.S.,
but not pursued here. The Chinese picked it up, developed it, set up a
company, and I believe it is now being traded on the U.S. stock
exchange. (I note that one hospital in Japan and three in Australia use
it for prostrate cancer!) Apparently the Chinese use it for all kinds of
cancer, including late stage cancers with about an 80% success rate.
Love, Pat

Conference considers ultrasound for cancer treatment,
noninvasive surgery

In what is only the second meeting of its kind, the first
conducted in the United States, more than 200 researchers and students
are expected in Seattle for presentations Tuesday through Aug. 1 as part
of an international symposium on therapeutic ultrasound. Presentations
will be conducted at the Washington Athletic Club.
Unlike the familiar use of ultrasound to obtain images inside
one's body to diagnose such things as tumors or check on the health of
an unborn child, therapeutic ultrasound is much more concentrated and
targeted and is used to treat medical problems not just diagnose them.
Treating kidney stones with ultrasound, called lithotripsy,
has been widely used since the 1980s. In just the last 10 years,
however, researchers have been developing high intensity focused
ultrasound devices to treat such problems as cancerous tumors, wounds
and internal bleeding. While one clinical trial to treat prostate cancer
is underway in the United States, therapeutic ultrasound already is
being used to treat cancer patients in Europe and China. High intensity
focused ultrasound can be used through the skin, making surgery
unnecessary and, when properly focused, it doesn't heat the tissue
between the device and the spot needing treatment the way lasers do.
Having attended the first international meeting in China last
year, Larry Crum of the University of Washington's Applied Physics
Laboratory said he brought the second meeting to the United States so
that medical professionals and researchers here could assess the
potential and decide which aspects might merit more investigation. Crum
is a physicist specializing in medical acoustics and is director of a
group of UW radiologists, surgeons and physicists investigating medical
and industrial uses of ultrasound.
Speakers include pioneer Christian Chaussy
-- The lead-off speaker Monday is Christian Chaussy the
German urologist who in the mid-'80s was the first in the world to treat
patients using sound energy to break up kidney stones. He will speak
about the use of high-intensity focused ultrasound to treat prostate
cancer patients in Europe. He also will receive a pioneer award from his
colleagues during the Seattle meeting.
-- Feng Wu of the Chongqing Medical University will describe
four years of clinical use of high-intensity focused ultrasound for
liver cancer, malignant bone tumors, breast cancer, soft tissue
sarcomas, kidney cancer, pancreatic cancer and other solid tumors. Crum
believes China is 2? years ahead of the rest of the world in developing
such treatments.
-- Michael Marberger of the University of Vienna will report
findings that high-intensity focused ultrasound used to treat prostrate
cancer may then enhances the body's own antitumor immune response.
15 sponsors
Crum secured sponsorship from the U.S. Army Medical Research
and Materiel Command, which oversees the development of medical
materials and logistics for the Army, and 14 other agencies, companies
and foundations. (NOTE: "Materiel" is the correct spelling.)
Registered to attend are faculty and researchers from
institutions including Johns Hopkins University, Mayo Clinic, Duke
University and the University of Tokyo. Representatives from more than a
dozen firms from countries such as France, Israel, Germany, the United
Kingdom and China are expected including the principals of the three
Chinese companies already building high intensity focused ultrasound
devices. The Chinese minister of health recently said he would like to
see one of these devices in every one of the more than 15,000 hospitals
that perform cancer surgery in China.
