(Medical-NewsWire.com, April 06, 2013 ) San Francisco, CA -- When it comes to liver tumors, the growth can either be benign or malignant. If the tumor is malignant then they can be a primary or a secondary classification. In Europe, a sole lesion in the liver is more likely to be metastatic carcinoma than a primary liver tumor, and the major risk factors of liver cancer are infections of hepatitis B or C along with heavy alcohol consumption. All of these most prevalent possible causes are cirrhosis.
Studies find that smokers and diabetics are at the most increased risk, while consumption of foods contaminated with aflatoxin can also cause the liver cancer to develop. Quite often, liver cancer does not expose symptoms until the later stages.
One of the most used methods to treat liver tumors ultrasound. Powerful concentrations of ultrasound waves can be focused on the patient to heat cancer cells to 60 Celsius. Up to now, the focused therapy has been approved for a select few diseases. Now, researchers from the FUSIMO project have worked on using the application to organs such as the liver.
Treating the liver with such FUS can cause some major problems however. The organ shifts back and forth during a patient's breaking. This increases the risk that the healthy tissue can be too heated. For this very reason there is general anesthesia which is often used. In order to treat a tumor with ultrasound, the medical ventilator is paused for a handful of seconds in order to create stillness. Still there are plenty of risks within anesthesia as well.
The FUSIMO team came up with a different strategy to combat such problems. If the ultrasound therapy applied to a moving liver can be simulated through virtual mediums, then the potential for utilizing the treatment on an organ without the anesthetic could work.
Two years on, the project has now reached an important headway, and experts have created software which they believe will allow liver operations to use ultrasound. Magnetic resonance data will build the foundation for a 3D image that will be utilized for the study.
It is a large step in the right direction for such advanced work, and while the tests are still being ironed out, the study is showing promise.
