Liver metastases and hepatocellular carcinoma
Robot-controlled cyberknife radiosurgery offers a treatment alternative for primary liver tumors and especially for metastases in the liver.
Tumors in respiratory organs such as the liver can be treated without fixation of the patient or anesthesia. The tracking technology of the Cyberknife system can follow the movement of the liver caused by breathing and still hit the tumor with an accuracy of about one millimeter. The surrounding liver tissue is spared. Therapy-related functional disorders of the liver are rare and the regenerative hepatic capacity is hardly affected. However, the focus of the liver must be marked in advance with a small gold fiducial. This is done externally with a CT-guided needle under local anesthesia.
