CyberKnife®: Tumor Removal Jeremy Galle BME 281 November 21st 2012

CyberKnife® Developed by Accuray Linear Accelerator (LINAC) machine Uses microwave technology to generate photons Weightless elementary particle Used in Stereotactic Radiosurgery Non-invasive form of radiation therapy Relies on: CT scan Determine location, size, shape of tumor Radiation Tumor DNA mutations Image-guided radiation therapy (IGRT) Computer-controlled robotic arm Custom treatment plan

Results January 2012 – 160 person case study conducted The People’s Liberation Army 107th Hospital in China 18 people had their tumors disappear 99 exhibited tumor shrinkage 35 were unaffected 8 had tumor growth Conclusion: 73.13% effectiveness

Advantages/Disadvantages Non-invasive No recovery time Can treat tumors anywhere in body Extremely accurate (within 0.5mm of target) Insurance can cover the costs Minimal to no side effects Disadvantages: Not always effective Expensive without insurance ($12,000 for one treatment) Results take time More than one treatment may be necessary Procedure is longer than comparable treatments (60-90 mins)

Future of the technology More effective No patients with reverse trends More accurate No surrounding tissue damage No side effects Quicker results Less expensive Quicker procedure times More flexible treatment plans
