Newswise — PHILADELPHIA – Today, Penn Medicine celebrated the groundbreaking of the Roberts Proton Therapy Center at in University City, which is expected to open for patient care in late 2027. The state-of-the-art, $224 million center will be Penn Medicine’s fourth proton therapy location, bolstering the organization’s system-wide approach to comprehensive cancer care. is an advanced form of radiation therapy used to treat many types of cancer by targeting tumors with pinpoint precision that protects surrounding, healthy tissue, thereby limiting side effects and preserving quality of life.
The new center is intended to expand the cancer care capabilities of Penn Medicine’s , and to build capacity in preparation for a planned update of the at the Perelman Center for Advanced Medicine, the largest and busiest center in the world for proton therapy, where nearly 11,000 adult and pediatric patients have been treated since it opened in 2010.
“Penn Medicine is an international leader in proton therapy treatment, research, and education, and this new proton therapy center will help ensure seamless patient care as we proactively plan for upgrading our flagship center at the Perelman Center,” said , chair of Radiation Oncology in the Perelman School of Medicine at the University of Pennsylvania. Upgrades to the Roberts Proton Therapy Center at the Perelman Center will begin several months after the center at Penn Presbyterian opens.
Expanding radiation therapy in University City
The new center will include two state-of-the-art Proteus®ONE proton therapy systems and involve a 43,000 square foot expansion, extending the footprint of Penn Presbyterian toward 38th Street. Medical Drive is currently closed while construction is ongoing. Patients and visitors should use Filbert Street to access Penn Presbyterian’s . Updates to construction impacts on wayfinding will be posted on the .
In addition to the two proton therapy systems, the project will add another treatment room for photon therapy, which uses high-energy X-ray beams, and is the most frequent form of radiotherapy in cancer treatment. The TrueBeam® photon therapy system will be up and running by fall 2025, doubling the capacity for photon therapy at Penn Presbyterian.
“We create a personalized radiation therapy plan for every patient, based on their specific cancer type and tumor location,” said , chief of Radiation Oncology and Proton Therapy at Penn Presbyterian Medical Center. “This new center will allow us to fully serve patients with the most advanced radiation therapy treatment options in both proton and photon therapy.”
Through a partnership with Children’s Hospital of Philadelphia (CHOP), specialty-trained pediatric radiation oncologists treat children at the Roberts Proton Therapy Center in the Perelman Center, and this partnership will extend to the new location at Penn Presbyterian as well.
Leading the world in proton therapy
While there are fewer than 50 proton therapy centers in the United States, patients in and around the Delaware Valley benefit from . In addition to the Roberts Proton Therapy Center at the Perelman Center, proton therapy is also available at the and the in South Jersey.
Penn Medicine uses a hub-and-spoke model where centralized experts—highly trained and experienced physicists and dosimetrists at the Perelman Center—create treatment plans for every patient receiving proton therapy and send those plans to the radiation oncologists administering treatment. This model allowed Penn’s proton therapy centers in Lancaster and South Jersey to get up and running quickly and will be implemented at Penn Presbyterian as well.
The new center will also allow Penn Medicine to expand proton therapy research activity and educational offerings. Penn Medicine proton therapy experts have trained staff from 27 proton therapy centers across the world over the last 15 years and led groundbreaking research to deliver proton therapy even more safely and precisely. Penn Medicine experts continue to lead large-scale clinical trials aimed at determining whether proton therapy offers better outcomes than conventional photon therapy for different types of cancer. For example, the ongoing is the largest clinical trial to date to compare proton and photon therapy for patients with locally advanced breast cancer. And Penn experts are leading the way in developing , a new strategy that could use proton or photon therapy to treat tumors with an ultra-high dose of radiation in less than a second.
