Mayo Clinic to build centers in Rochester, MN. and Phoenix; McLaren brings proton therapy to Flint, MI.

The National Association for Proton Therapy (NAPT) today announced three new supporting member sites including Mayo Clinic proton beam therapy program under development in Rochester, Minn. and Phoenix; and the McLaren Proton Therapy Center, currently under construction in Flint, Mich. Today’s announcement brings to seven the total number of proton sites now in planning or under construction in the U.S. Nine centers are fully operational.

“NAPT is pleased to welcome Mayo Clinic and McLaren Health into our small, but growing community of proton therapy centers. We look forward to the day when more cancer patients will have greater access to the best available radiation treatment that will reduce morbidity and side effects and optimize patients’ quality of life ,” said Leonard Arzt, executive director of NAPT.

Mayo Clinic will utilize proton therapy in the form known as intensity modulation, or IMPT in the form of pencil beam scanning in eight treatment rooms at the two locations. The centers plan to treat patients as early as 2015 with a focus on cancers of the head and neck, breast, lung, spine, prostate, eye, stomach and pediatric cancers.

The three-room, 35,000 sq. ft. McLaren facility will use IMPT as soon as 2012 at McLaren’s Great Lakes Cancer Institute. The treatment delivery system will also use robotic table positioning. McLaren has partnered with ProTom International, a Texas-based health care technology company using the Radiance 330 system. It will be the first proton center in Michigan. “We are very excited to bring this life-saving technology to our patients,” said Philip A. Incarnati, president of McLaren Health Care.

About Proton Therapy:
Proton beam therapy is an advanced form of radiation therapy used in cancer treatment. It is available at nine operating centers with at least seven additional facilities in the planning and construction phase. Unlike standard (X-ray) radiation treatment, proton therapy uses radioactive particles that can be precisely conformed to target the tumor. The advantage of protons is that higher doses of radiation can be delivered to control and manage cancer while significantly reducing damage to healthy tissues and vital organs.

About NAPT:
NAPT is supported by proton center members and is the Voice of the Proton Community. NAPT promotes education and public awareness about the clinical benefits of proton beam radiation therapy. It was founded in 1990. For more information and a list of proton centers, visit
