Top Score in Multiple Brain Metastases TROG 2018 Treatment Plan Study Achieved With Accuray Precision

Results demonstrate high treatment plan quality achievable with Accuray treatment planning software (TPS)

May 24, 2018 — Daniela Schmitt, Ph.D., took top honors in the overall category of the 2018 TROG Plan Study: Stereotactic Radiosurgery (SRS) Brain, with a plan she created using the Accuray Precision Treatment Planning System. Schmitt, a medical physicist at Heidelberg University Hospital, Germany, developed a plan for delivery on the CyberKnife M6 System, a device designed from the ground up to deliver SRS treatments with precision and accuracy, and without an invasive frame.

The study, hosted by TROG Cancer Research and ProKnow, received 160 entries from clinicians around the world. Of these submissions, only 10 percent were plans produced by the proprietary Accuray Precision System or the MultiPlan TPS for the CyberKnife platform. The remaining 90 percent were created using treatment planning software for other delivery systems.

The goal of the study was to quantify the capabilities of different planners and delivery modalities to create high-quality treatment plans for a challenging SRS case with five small brain metastases. The plans were scored based on target coverage and organ-at-risk (OAR) sparing, defined by specific metrics. Evaluation of the plans was objective and transparent with real-time scoring and analysis.

"It was a great experience to compete with all available systems for SRS treatments," said Schmitt. "We often use the CyberKnife to treat patients with multiple brain metastases and now have confirmation of our good clinical practice. Treatment planning studies like this can help the whole community to find the best solution with their systems and to achieve the best daily clinical treatment plans based on the lessons learned."

The Accuray Precision System is a full-featured treatment planning system, enabling clinicians to efficiently generate high-quality radiation therapy treatment plans for all SRS and stereotactic body radiation therapy (SBRT) cases delivered by the CyberKnife System.

Key features include:

  • Treatment planning is faster and easier to perform, without sacrificing precision and accuracy in radiation dose delivery;
  • Simplified workflows, automated contouring and plan automation tools support highly efficient plan generation for even the most complex clinical cases; and
  • Defining the target and OAR correctly can be achieved easily due to multimodality images and automated contouring tools.
