The results of a new trial for the treatment of metastases in the liver starting from a primary tumor in the colon show that CyberKnife represents an additional treatment option. This may, in addition to chemotherapy or even when made inoperable metastases in general.

For the study, which is now published in European Journal of Cancer online (Stintzing et al.), Physician of the LMU-University Hospital and the European CyberKnife Centre in Munich-Grosshadern have patients with colorectal metastases and treated. The average age is 65 years, the patients were followed for an average period of 16.8 months. Of these, 87% survived the first year after treatment, average survival time prolonged by 9.2 months. In order to physicians is in any case the most interdisciplinary team another option for the treatment of metastases in the liver due to a bowel cancer available. Further studies with larger patient population over a longer period are currently in the planning.

In the CyberKnife technology is the most innovative photon therapy. The main task of radiation surgery is the high-precision irradiation of a precisely defined target volume. These are the healthy parts of the body in the tumor environment as little as possible are made by rays. To achieve this, first is a treatment device with an appropriate radiation type and energy selected and irradiates the tumor region from different directions. With the flexible technology, the CyberKnife irradiation unit rotates around the patient - typically up to 150 per (possible from 1400) set beam treatment. the spectrum because of published scientific studies and proven efficacy to currently ranges from the irradiation of tumors in the brain, the eye of the spine and pelvis as well as in lung, liver, and partly also to the prostate.

The first CyberKnife center in Germany on 1 July 2005 in cooperation with the University of Munich (LMU) opens. Using a high-precision image-guided robot control can be addressed destroying a tumor dose of radiation to a precisely defined target volume, while the surrounding healthy structures are preserved. In the treatment of overlapping weak beams from many different directions in the tumor, where they add up to total dose. Through the development of the CyberKnife technology integrated with a combination of image guidance and robotic control to draw a completely new, non-invasive treatment option. Meanwhile, in Munich more than 2,500 patients have been treated with this method.

Dr. med Muacevic Alexander, who heads together with Prof. Dr. Berndt Wowra the European CyberKnife Centre in Munich-Grosshadern, is also President-Elect of the international CyberKnife Supervisory Board. In the area of treatment of patients with diseases of the brain, the Munich Radio surgeons are world first. Across all disease areas they take away a rank 3, for a total of 190 worldwide CyberKnife centers
