Executive Director Message


StuartKlein.pngThe building addition that will house our new single-room proton therapy system has reached several construction milestones. We marked a capping off in May with the final concrete pour. Since then, the exterior walls have been installed and interior work is progressing. Within the next few months, we will receive delivery of the proton therapy system – the cyclotron and gantry. This technology will add to our existing array of proton therapy, conventional radiation therapy and imaging equipment, currently considered the most advanced radiation oncology facility in the Southeast U.S. In the hands of our expert physicians, physicists, nurses and radiation therapists, this advanced technology is used to offer patients the highest quality cancer care and the best chance for excellent results. Our stature as a leading proton therapy facility has never been stronger, and we look forward to continuing to serve the needs of cancer patients in our region and beyond.

Second-Consecutive ACR Accreditation Earned

The American College of Radiology Seal

The American College of Radiology has awarded a three-year term of accreditation in radiation oncology to the University of Florida Health Proton Therapy Institute. This is the second consecutive accreditation awarded to the UF Health Proton Therapy Institute and is a distinction earned by facilities that meet or exceed national standards in radiation oncology.

Of the 27 proton therapy centers in the U.S., the UF Health Proton Therapy Institute is one of 11, and the only one in Jacksonville, to earn the ACR seal of accreditation representing the highest level of quality and patient safety.

ACR reviewers described the UF Health Proton Therapy Institute as a “high-quality, well-staffed, well-organized facility and operation,” and commended it for its “clear documentation and high safety measures” as well as for following “guidelines for therapy decisions and practice.”

Nancy P. Mendenhall, M.D., medical director of the UF Health Proton Therapy Institute and associate chair and a professor of radiation oncology at the UF College of Medicine, said the accreditation is a testament to the medical team’s commitment to excellence.

“We are a regional resource for proton therapy, and patients rely on us to deliver safe, effective cancer treatment,’’ she said. “It is an honor to earn this recognition from a panel of peers who are tasked with providing a rigorous, impartial review.”

The ACR is the nation’s oldest and most widely accepted radiation oncology accrediting body, with over 700 accredited sites and 30 years of accreditation experience. The ACR seal of accreditation is awarded only to facilities meeting specific practice guidelines and technical standards developed by ACR after a peer-review evaluation by board-certified radiation oncologists and medical physicists who are experts in the field. Patient care and treatment, patient safety, personnel qualifications, adequacy of facility equipment, quality control procedures, and quality assurance programs are assessed. The findings are reported to the ACR Committee on Radiation Oncology Accreditation, which subsequently provides the practice with a comprehensive report they can use for continuous practice improvement.

The ACR is a national professional organization serving more than 36,000 diagnostic/interventional radiologists, radiation oncologists, nuclear medicine physicians, and medical physicists with programs focusing on the practice of medical imaging and radiation oncology and the delivery of comprehensive health care services.


Randal Henderson, M.D., M.B.A. – An Expert Talks About Prostate Cancer and Proton Therapy

Bringing awareness to prostate cancer is the first step in early detection and effective treatment. Randal Henderson, M.D., M.B.A., associate medical director of the UF Health Proton Therapy Institute and a professor of radiation oncology at the UF College of Medicine, is an expert in prostate cancer treatment. He was recently interviewed about the benefits of proton therapy in treating the disease. Dr. Henderson discusses the excellent patient outcomes reported in published studies and the new national clinical trial being led by the Institute that will compare the outcomes of patients treated with proton therapy or conventional radiation therapy.

Cruise Organized by Proton Alum

Next April, proton alumni are setting sail aboard a cruise liner in the Mediterranean, and you’re invited. Organized by Rose and George Rollins (alum 2018), it is meant as an informal reunion for proton alumni. According to the Rollinses, it’s a chance to celebrate successful treatment, relax and share how the UF Health Proton Therapy Institute has impacted proton graduates’ lives post treatment.

“This cruise is a personal endeavor by three couples who bonded in treatment at the Proton Center and who want to continue that relationship,” said the Rollinses. “We also want to include other graduates who might be interested in this celebration cruise.”

The ship is Holland America’s Koningsdam, christened in 2016. Originating in Civitavecchia (Rome), Italy, the nine-day, six-port Mediterranean cruise will visit Croatia, Greece and Italy.

The Rollinses are retired airline employees and have contacted Holland America’s Group Administration Department directly to set up the proton alumni group.

For more information, contact George and Rose Rollins at 678-907-9339 or geonrose@bellsouth.net.
