CyberKnife customers pioneered prostate SBRT. Two studies confirmed the durability of the clinical response after 4- or 5-fraction CyberKnife SBRT in 640 early-stage prostate cancer patients followed for at least 10 years1,2.
Breast Cancer
Multiple studies reinforce the benefits of treating early stage breast cancer with TomoTherapy or CyberKnife for partial breast irradiation (PBI).
Three hundred and thirty-eight patients treated in 10 fractions delivered with the TomoTherapy System and followed for 72 months showed excellent long-term results with good to excellent cosmetic outcomes, reinforcing the role of the system in the treatment of early stage breast cancer3.
Two studies evaluating 5-fraction CyberKnife PBI and following patients for 36 months and 80 months, respectively, confirmed that treatment was well-tolerated and efficacious4,5. Moreover, for the first time at ASTRO, the preliminary results of a 1-fraction treatment delivered with the system were reported. The results for 19 patients are promising in terms of feasibility, cosmesis and early outcomes, potentially expanding the treatment options clinicians offer their patients6.
ClearRT™* Helical kVCT Imaging for the Radixact® System: Unveiled at ASTRO
The most recent innovation for the Radixact System, ClearRT Helical kVCT Imaging, is intended to quickly and cost-effectively produce clear, high-fidelity kVCT images that enhance soft-tissue visualization to improve cancer patients' care. With the introduction of ClearRT for the Radixact System, Accuray is delivering on the full promise of the system's unique helical architecture. The Radixact System is the only radiation therapy device with helical imaging, helical delivery, and intrafraction motion synchronization functionality using Synchrony®, providing expanded versatility and increased precision to treat the widest range of cases - from simple to the most complex - with the longest continuous imaging and treatment fields in the industry, up to 135 cm.
*ClearRT™ Helical kVCT Imaging for the Radixact Treatment Delivery System is 510(k) pending and is not available for sale in any market.
"We are pleased to have had the opportunity to present our latest innovations during this important meeting. Our radiation delivery systems and software solutions provide medical care teams with cutting-edge options for expanding the range of patients who may benefit from treatment. We continually invest in transforming what radiation therapy can do, with the goal of providing clinicians with more efficient and effective options that can handle even the most challenging cases, to get patients back to living their lives, faster," said Suzanne Winter, chief commercial officer and senior vice president, R&D at Accuray.
