Proton therapy

Louvain-la-Neuve, Belgium, 20 October 2018 - IBA (Ion Beam Applications SA), the world’s leading provider of proton therapy solutions for the treatment of cancer, and Willis-Knighton Proton Therapy Center, home of the first compact Intensity Modulated Proton Therapy unit installed in the world, are pleased to announce a record mean time in the treatment room of 16 minutes per patient achieved with the single room Proteus®ONE solution. The clinical team at Willis-Knighton Proton Therapy Center has reached workflow excellence while treating a large range of indications, from simple to highly complex cases, such as brain, breast, lung, prostate, central nervous system, gynecological, and gastrointestinal tumors.

Proteus®ONE is the only truly compact Image-Guided Intensity Modulated Proton Therapy (IG-IMPT) solution in the industry. It has a unique open gantry designed to ease the work of radiation therapists during treatment through an efficient workflow, optimizing the patient experience with a comfortable and calming environment. Combined with the unique instantaneous oblique imaging system and  Cone Beam CT at isocenter, the open gantry enables treatment of a wide range of indications including traditionally difficult cases such as vertex fields for Central Nervous System (CNS) and Head & Neck tumors.  Treating non-coplanar fields with an open gantry is easier compared to a less spacious closed gantry.

Olivier Legrain, Chief Executive Officer at IBA,commented: “We are delighted to see our first Proteus®ONE clinical partner reaching clinical excellence in the fight against cancer. This accomplishment reinforces the vision we had more than 5 years ago when we launched Proteus®ONE to make proton therapy more affordable, quicker to install, and easier to operate. Today’s milestone at Willis-Knighton provides confirmation that our open gantry solution is the right choice for proton therapy as a treatment option for the patients.”

Lane R. Rosen, MD, Radiation Oncology Medical Director, Willis-Knighton Health System, added: “Our proton therapy center has been a great achievement in the development of cancer care in our community and Louisiana. Using the Proteus®ONE solution, our team has treated a diverse group of tumors with a dramatic reduction in treatment related side-effects. Furthermore we have a strong CNS and brain tumor program and with the open gantry we are able to treat a vertex field very easily.”

Terry Wu, PhD, Chief of Physics, Willis-Knighton Health System, stated: “The experience accumulated while treating patients in Shreveport over the last 4 years shows that Pencil Beam Scanning Proton Therapy can be safely and efficiently delivered to a wide variety of body sites using both volumetric/CBCT and stereoscopic image-guidance. With a record mean time in the treatment room of 16 minutes per patient and a wide range of indications, the optimized workflow of the Proteus®ONE treats up to 20% more patients than other competitive systems.”
