Healthcare Industry News: TrueBeam
News Release - June 2, 2014
Doctors at Community Cancer Center Treat Inoperable Lung Cancer Using TrueBeam System for Image-Guided Radiotherapy and RadiosurgeryNORMAL, Ill., June 2, 2014 -- (Healthcare Sales & Marketing Network) -- When a diagnostic chest X-ray revealed a nodule on his left lung, Paul Hoffman, 79, had a biopsy and soon got bad news: it was Stage 1 lung cancer. He was given two options. The first was surgery, which would have been risky because Hoffman has a heart condition and a pacemaker. The second option was radiosurgery—a non-invasive treatment that uses finely shaped radiation beams to target a tumor without making a single incision.*
Patrick Fernandes, M.D., radiation oncologist, designed Hoffman's treatments to carefully target his lung tumor while minimizing exposure of nearby healthy tissues and organs, especially the spinal cord, rib cage, esophagus, and the delicate healthy lung tissues that surrounded the tumor.
"For patients with heart or lung problems, conventional surgery can be risky," said Fernandes. "Stereotactic body radiotherapy, or SBRT, can be a viable option for these patients, and often leads to good local tumor control. We use very high doses with the goal of completely destroying the tumor." *
Each of Hoffman's five treatments was completed in about ten minutes, using RapidArc radiosurgery. "RapidArc is a capability of the TrueBeam machine that enables us to modulate the dose, vary the speed of rotation around the patient, and continually shape the treatment beam in a way that dramatically shortens the duration of each treatment," Fernandes said. "Similar treatments using other technologies could have taken as long as an hour each day."
"The hardest part of the treatment was having to hold a position with my arms over my head," Hoffman said. "That's the only thing that bothered me at all. I'm 79 years old and don't move as well as I used to. Fortunately, when it was time for my treatment, the TrueBeam machine was in and ready to go. I was one of the first patients. Otherwise, I'd have been treated on another machine, and I'd have had to hold still with my arms up for 25-30 minutes at a time, which would not have been fun."
Hoffman says that the biggest side effect of treatment was feeling tired for a couple of weeks, but it was nothing like the fatigue his wife experienced when she was treated for breast cancer many years ago. "I assumed that would happen to me, and it didn't. I was tired, but it wasn't debilitating," he said.
It will be another three to six months before Hoffman is brought back for follow-up scans, said Shermian Woodhouse, M.D., radiation oncologist and cancer center medical director. "There's every reason to hope that we'll see no more evidence of the tumor in the best case scenario, and shrinkage of the tumor at the least," she said. "That would be in line with our prior experience, and also, the medical literature on the use of stereotactic body radiotherapy to treat inoperable lung cancer."1,2,3,4
Since its installation at the end of March, clinicians at the Community Cancer Center have used the TrueBeam machine to treat cancer of the lung, breast and multiple other disease sites.
"Having the TrueBeam STx makes it possible for us to offer more varied treatment options to a wider range of patients," said Woodhouse. "The system also offers us more tools for ensuring and documenting the accuracy of treatments. From the perspective of our staff, it has enabled a significant improvement to our workflow. Since it was installed, I've seen an increase in staff morale. Our people know that the Cancer Center is dedicated to providing them with the tools they need to do their jobs really well."

*Radiosurgery or SBRT may cause side effects that can vary depending on the part of the body being treated. The most frequent ones are typically temporary and may include, but are not limited to, irritation to the respiratory, digestive, urinary or reproductive systems, fatigue, nausea, skin irritation, and hair loss. In some patients, they can be severe. Treatment sessions may vary in complexity and time. Radiation treatment is not appropriate for all cancers. Patients should discuss the potential for side effects and their severity as well as the benefits of radiation with their doctors to make sure radiation treatment is right for them.
