Sharing new ideas, methods and best practices in proton therapy makes the conference valuable to attendees.
“It was good to network with people from other centers to learn how they are using their fixed beam and incline beam rooms,” said Shepherd. “I was especially interested in the presentation on using the fixed beam to treat the cranio-spinal region for leptomeningeal disease. That’s something that I would like to explore here [at Fred Hutch].”
Shepherd was also able to brainstorm with other providers on potential clinical trials for thymoma and kidney cancer patients and listened to the latest finding that proton therapy shows promise of advantages for patients with head and neck, esophageal and central nervous system tumors.
“Dr. Stephen Frank from MD Anderson presented data from a clinical trial showing lower dependence on feeding tubes in the patients treated with protons compared to IMRT [intensity modulated radiation therapy] for head and neck cancers,” she said.
Fred Hutch radiation therapists, Katelyn Grozelle and Terry Prescott, learned about new technology offerings at the conference, including the use of artificial intelligence in medicine. Incorporating AI into the workflow allows physicians to focus on complex cancer cases.
“They can use it to contour organs at risk during dosimetry planning, which reduces the time needed to create a custom plan,” said Prescott. “Over time, the AI learns preferences and can adapt, making it more efficient.”
However, human oversight is always needed.
Grozelle and Prescott also learned about advances in FLASH technology, which is currently being studied at Fred Hutch’s proton therapy center. FLASH radiation therapy uses ultra-high-speed radiation (which gives radiation 100 to 1000 times faster than usual) to decrease toxicity from radiation treatment. Only a few institutions are able to conduct this research because of the technical expertise required.
“I was especially interested to see what’s inside the treatment nozzle,” Prescott said. “Seeing this has made me better understand the process and strengthened my knowledge on the subject.”
Grozelle added how technology is always changing and advancing.
“It was exciting to see the custom devices Penn has made for their FLASH treatments. They currently use it to treat cancer in dogs,” she said. “The next step will be a clinical trial using FLASH to treat head and neck cancer patients.”
Because the University of Pennsylvania uses the same cyclotron vendor as Fred Hutch, Grozelle also met with her colleagues to discuss best practices during a site visit.
“We were able to see their gantry rooms and ask questions about workflow and setups. They also use cone beam CT, something we are currently installing in our gantry,” she said. “I was able to ask the therapists for any feedback they had using this type of imaging.”
For the Fred Hutch proton therapy team, the conference provided a meaningful opportunity to engage with the broader proton therapy community and exchange innovative ideas, techniques and best practices aimed at advancing patient care.
