The CyberKnife’s flexible robotic arm provides unparalleled access to previously unreachable tumors with submillimeter accuracy. CyberKnife is noninvasive, so doctors can treat multiple tumors without making a single incision.

“Cutting Edge Treatment Without the Cutting”

What makes UNC a cut above the rest?

  • Only academic cancer center in central North Carolina with CyberKnife
  • One of only five National Cancer Institute (NCI) designated Comprehensive Cancer Centers in the US with CyberKnife
  • A multidisciplinary team of UNC specialist doctors and other healthcare professionals involved in patient care

An open letter to referring physicians:

Dear Colleagues,

Thank you very much for your continued support of the UNC CyberKnife Radiosurgery Program. We appreciate you entrusting us with the care of your patients. Our CyberKnife program has been quite successful to date, and our patient volumes continue to increase, reflecting the need for this type of therapy for the ablative treatment of small lesions in virtually any part of the body. With the growing volumes, we are pleased to announce that we now have multiple physicians in Radiation Oncology credentialed in CyberKnife treatment.

  • Dr. Ronald Chen (Radiation Oncology CK Program Associate Director) joined our faculty in July, 2009. Dr. Chen was trained at Harvard and is heading up our prostate/GU services. He has a long-term interest in stereotactic radiation therapy treatments for all tumors types, and is fully trained to use the CyberKnife.
  • Dr. Andrew Wang joined our faculty in July, 2009, and was also trained at Harvard. Dr Wang is active in laboratory research studying nanotechnology and clinically in our GI and GU programs. Dr. Wang is also fully trained to use the CyberKnife for all tumors.
  • Dr. Bhisham Chera was trained at the University of Florida in Gainesville and also joined us in July, 2009. Dr. Chera is leading our clinical program in head and neck cancer and is fully trained to use the CyberKnife.
  • Dr. Joel Tepper, former Chair of the Department of Radiation Oncology, is seeing new patients for consideration of CyberKnife treatment for upper abdominal tumors (e.g., liver).

We are thrilled to have the increased clinical expertise and services of these outstanding physicians as part of our CyberKnife team.

At UNC, CyberKnife is a multidisciplinary endeavor that pairs radiation oncologists with oncologic surgeons. As such, your patients are usually seen by surgeons who have also been specifically trained to perform CyberKnife procedures (Drs. Matt Ewend, Deanna Sasaki-Adams, and Sivakumar Jaikumar in Neurosurgery; Dr. Craig Buchman in Head and Neck Surgery; Dr. Thomas Egan in Thoracic Surgery; and Dr. Jonathan Dutton in Ophthalmology), in addition to one of our radiation oncologists.

UNC remains a leader in the field of Cyberknife radiosurgery, with our physicians authoring multiple publications and book chapters focused on radiosurgery.

Please contact Lauria Themes (984-974-8452), our CyberKnife program coordinator, to assist in scheduling your patient’s care. Appointments can also be made through our general scheduling hub at (984) 974-8415.

Please let me know if you have any questions or concerns.
