St. Joseph’s Cancer Institute Unveils New Technology in Cancer Treatment Options

(STOCKTON, CA) April 20, 2023 – St. Joseph’s Cancer Institute and St. Joseph’s Foundation of San Joaquin are excited to unveil the TrueBeam Linear Accelerator, the most advanced technology available to help fight cancer. This new linear accelerator combines imaging, beam delivery and sophisticated motion management to accurately and precisely target tumors with speed. 

“We are proud to offer this breakthrough technology to the San Joaquin community,” said Donald J. Wiley, President and CEO of St. Joseph’s Medical Center. “This new sophisticated  linear accelerator will allow us to tailor treatment to an individual's needs that are best for each patient's condition, leading to higher success rates.” The linear accelerator provides breakthrough tools that allow our radiation oncology team to treat more challenging cancers, such as pancreatic, paraspinal, lung, liver, breast, brain and prostate. This precision also allows for higher doses of radiation, given in less time, and with less impact on healthy tissue. Other benefits include:

  • Shorter course of treatment - for some, it will reduce from 5-7 weeks to 1-3 days
  • Daily treatment times reduced by as much as 70%
  • Increased success treating early-stage cancers with the new technology

"With the addition of the True Beam and the use of HyperArc, we are bringing state-of-the-art radiation therapy to this community that previously could only be obtained in a university setting,” said Dr. Gauravjit Singh, MD, Radiation Oncology, St. Joseph’s Medical Center. “It's a real game changer; we will now be able to treat multiple tumors in a patient's body simultaneously. This is going to improve the patient's experience, making it quicker, more effective and safer for them.”

The linear accelerator is part of a larger $9.2 million project at the St. Joseph’s Cancer Institute, which consists of designing and building the linear accelerator vault, the TrueBeam equipment, and the specialty software. The project also includes ADA upgrades to patient dressing rooms and nursing stations in the Cancer Institute.
