The National Cancer Center Hospital in Tokyo upgrades its MRIdian® Linac for MRI-guided radiation therapy and has treated its first patients

The largest cancer center in Japan Improves its real-time soft tissue tracking and adaptive tabletop delivery with the MRIdian system

CLEVELAND, August 11, 2022 /PRNewswire/ — ViewRay, Inc. (NASDAQ: VRAY) today announced that the National Cancer Center Hospital (NCCH) of Japan upgraded its Cobalt MRIdian® MRI-guided radiation therapy system to the MRIdian Linac system and treated its first patients. The MRIdian system will enable the National Cancer Center Hospital to offer advanced MRI-guided radiation therapy technology to cancer patients seeking personalized treatment for pancreatic, prostate, lung, liver, breast and oligometastatic cancers.

CNC purchased its first MRIdian system in September 2016 after Shonin’s approval of Japan’s Ministry of Health, Labor and Welfare (MHLW) cobalt system the previous month. On the July 25, 2022, NCCH treated its first patient with a full table-top adaptive workflow on MRIdian’s enhanced version of Linac. MRIdian Linac features a linear accelerator and enables daily table-top adaptive radiation therapy and real-time monitoring to dynamically adjust radiation beam delivery for subtle anatomical changes that may occur, both during the delivery of the treatment and throughout treatment. Combined, these capabilities help clinicians improve targeting accuracy and therefore deliver higher radiation doses.

“Over the past 6 years we have seen firsthand the benefits of real-time MRI guidance and tabletop adaptive treatment delivery and its value in improving outcomes for cancer patients, we are therefore looking forward to integrating the MRIdian Linac system to further enhance our MRI-guided radiotherapy offerings,” said Dr. Kazuaki Shimada, director of the National Cancer Center Hospital. “MRIdian’s triggering technology is second to none and allows us to be aggressive in our delivery of stereotactic body radiation therapy, as we can be confident that the dose is precisely hitting the target without collateral damage to surrounding healthy tissue, can deliver the best care medical services to society,” said Dr. Hiroshi IgakiHead, Department of Radiation Oncology.

Japan is the world’s third-largest radiation oncology market, and the National Cancer Center Hospital is one of the from Japan leading national cancer treatment centers providing patient care for over 60 years. The National Cancer Center is at the forefront of cancer treatment research and plays a central role in training doctors, nurses, and other healthcare professionals to specialize in cancer medicine.

The MRIdian system provides oncologists with exceptional anatomical visualization through diagnostic-quality MRI images and the ability to tailor a radiation therapy plan to the targeted cancer with the patient on the table. This combination allows physicians to set narrow treatment margins to avoid unnecessary radiation exposure to vulnerable organs at risk and healthy tissues and allows the delivery of ablative radiation doses in five treatment sessions or less, without relying on implanted markers. By providing continuous real-time tracking of the target and organs at risk, MRIdian enables automatic radiation beam triggering if the target moves outside of user-defined margins. This allows the prescribed dose to be delivered to the target, while sparing surrounding healthy tissue and critical structures, minimizing the toxicities typically associated with conventional radiation therapy.

Nearly 25,000 patients have been treated with IRMdian. Currently, 53 MRI systems are installed in hospitals around the world where they are used to treat a wide variety of solid tumors and are the subject of many ongoing research efforts. MRIdian has been the subject of hundreds of peer-reviewed publications, scientific meeting abstracts and presentations.

Security statement
The MRIdian Linac system is not suitable for all patients, including those who are not candidates for magnetic resonance imaging. Radiation therapies can cause side effects that can vary depending on the part of the body being treated. The most common are usually temporary and may include, but are not limited to, irritation of the respiratory, digestive, urinary, or reproductive systems; fatigue; nausea; skin irritation; and hair loss. In some patients, side effects can be serious. Treatment sessions can vary in complexity and duration. Radiation therapy is not appropriate for all cancers. You should discuss the potential for side effects and their severity and the benefits of radiation therapy and magnetic resonance imaging with your doctor to make sure radiation therapy is right for you.

About ViewRay
ViewRay, Inc. (Nasdaq: VRAY), designs, manufactures and markets the MRIdian® MRI-guided radiation therapy system. MRIdian is built on a proprietary high-definition MR imaging system designed from the ground up to meet the unique challenges and clinical workflow of advanced radiation oncology. Unlike MRI systems used in diagnostic radiology, MRIdian’s high-definition MRI has been specifically designed to address specific challenges including beam distortion, skin toxicity, and other issues that can arise when high magnetic fields interact with beams of radiation.
