The CyberKnife system is used to treat a great variety of intracranial and extracranial indications. As a general guideline the following conditions and indications are available for procedures:
INTERCRANIAL GUIDELINES
| Radiosurgery is Indicated |
- As an Adjunct or planned "boost" after conventional external beam radiation therapy (XRT)
- As an alternative to conventional XRT, especially for radioresistant tumors
- For tumor recurrence in previously irradiated Regions. These patients usually have no other Option.
- As an alternative to conventional surgery:
- Equivalent outcomes in some cases
- Medical condition may preclude surgery
- Patient preference is a large factor
|
- Meningioma
- Pituitary Adenoma
- Acoustic Neuroma
- Other Cranial nerve Schwannomas
- Glomus Jugulare Tumors
- Residual/recurrent low-grade Astrocytoma Oligodendroglioma, Hemangioblastoma
|
- Metastatic Tumors
- Malignant Gliomas
|
- Arteriovenous Malformations (AVM)
- Cavernous Malformations/AOVM
|
- Trigeminal Neuralgia
- Cluster Headache
|
- Recurrent or residual head and neck tumors after conventional treatment
|
EXTRACRANIAL GUIDELINES
- Selected solitary metastases without bony spinal cord compression
- Primary treatment of classically radioresistant solitary tumors, i.e. melanoma, renal cell, and sarcoma
- Recurrent solitary metastases after Conventional radiotherapy
|
- Stage I NSCLC if medically inoperable or if patient refuses open surgery
- Advanced state NSCLC as a boost treatment
- Up-front treatment of obstructing endobronchial lesion with post-obstructive pneumonia
- Metastases: solitary or limited (2-5) multiple metastases if symptomatic or enlarging on serial imaging with a favorable survival profile
|
- Metastases: solitary or limited (2-5) multiple metastases if symptomatic or enlarging on serial imaging with a favorable survival profile
|
- Up-front radio surgery treatment of unresectable tumor "sandwiched" between chemotherapy doses
- Boost treatment for persistent PET-positive region after conventional chemotherapy and radiation therapy
|
- Renal cell cancer in medically inoperable patients
|
- Low-risk prostate cancer as an alternative to multi-week IMRT, low dose brachytherapy or high-dose brachytherapy (HDR)
|
- Fro vaginal cuffs as primary or as boost
|
Note: Other conditions may be treatable, please consult the CyberKnife Center for a recommendation.
