Actual dose variation of parotid glands and spinal cord for nasopharyngeal cancer patients during radiotherapy

Daily image-guided setup corrections can eliminate significant dose variations to critical structures. Constant monitoring of patient anatomic changes and selective replanning should be used during radiotherapy to avoid critical structure complications.

CyberKnife radiosurgery for breast cancer spine metastases

The statistical comparability of the CyberKnife and CRT groups reflects the small sample size and stringent requirements for significance of the matched-pair analysis. Nevertheless, comparability in these difficult cases shows that salvage CyberKnife treatment is as efficacious as initial CRT without added toxicity.

CyberKnife radiosurgery for benign intradural extramedullary spinal tumors

Although more patients studied over an even longer follow-up period are needed to determine the long-term efficacy of spinal radiosurgery for benign extra-axial neoplasms, short-term clinical benefits were observed in this prospective analysis. The present study demonstrates that CyberKnife radiosurgical ablation of such tumors is technically feasible and associated with low morbidity.

Cost-utility analysis of the CyberKnife system for metastatic spinal tumors

Accuracy of CyberKnife spinal radiosurgery using skeletal structure tracking

The Xsight spine tracking system is practically important because it is accurate and eliminates the use of implanted fiducials. Experience has shown this technology to be robust under a wide range of clinical circumstances.

T6 Spinal Solitary Breast Metastasis

The treatment of both malignant as well as benign tumors of the spine using CyberKnife radiosurgery began in 1997. Treatment of spine lesions using single fraction radiosurgery has been a successful treatment strategy at UPMC over the past four years.
