Long-term Survival in Patients Treated with a Robotic Radiosurgical Device for Liver Metastases.

Purpose: The treatment of liver metastases with local procedures is a fast progressing field. For the most, long-term survival data is missing raising questions with regard to the efficacy of such modalities when compared to surgical resection. Radiosurgery using the CyberKnife device enables the treatment of liver lesions with a single-session approach.
