A technique for stereotactic radiosurgery treatment planning with helical tomotherapy.

A robust and efficient planning technique was identified to produce plans of radiosurgical quality using the TomoTherapy treatment planning system. Dose calculation did not exceed a few hours and resulting delivery times were less than 1 hour, which allows the process to fit into a single day radiosurgery workflow. Plan conformity compared favorably with published results for gamma knife radiosurgery. In addition, plan homogeneity was similar to linac-based approaches.

Posterior Fossa Renal Cell Metastasis

Due to the tumor location, stereotactic radiosurgery (SRS) was indicated in favor of operative surgery. The patient proactively inquired six months prior regarding the possibility of CyberKnife® treatment should she develop recurrent disease in the lung or brain. SRS is a well recognized technique for the treatment of cerebellar renal cell carcinoma metastases.

Treating liver metastases from colorectal cancer with the CyberKnife System

This prospective, multicenter study is intended to establish the efficacy and toxicity of treating unresectable colorectal liver metastases with accurately administered radiation using the CyberKnife stereotactic radiosurgery system.

Treating inoperable early stage lung cancer with the CyberKnife System

The purpose of this study is to assess the short and long-term outcomes after CyberKnife stereotactic radiosurgery for early stage non-small cell lung cancer (NSCLC) in patients who are medically inoperable.
