Liver cancer patients among the first to receive treatment using fast, precise new system optimized for radiosurgery
TAICHUNG, Taiwan - Doctors at the Cheng Ching General Hospital here have begun treating liver cancer with image-guided radiosurgery using a new TrueBeam(TM) STx system from Varian Medical Systems (NYSE:VAR). The hospital has developed a program for treating hepatocellular carcinoma (HCC), a common type of liver cancer that is widespread in Asia.
"With TrueBeam STx, we can generate images of the tumor during the treatment, and use them to adapt the treatment in 'real-time.' This helps us to better target the liver tumor and minimize exposure of nearby critical organs like the duodenum or the stomach," said Dr. Po-Ming Wang, chief radiation oncologist at the hospital.
Dr. Wang is an expert in treating HCC, which is globally the third leading cause of cancer mortality after lung and stomach cancer, and a significant problem in Taiwan, mainland China, and other parts of Asia.(1)
The new TrueBeam system at Cheng Ching General Hospital is the first in Taiwan. Over the previous four years, Dr. Wang and his colleagues treated difficult cases of HCC using an earlier generation of Varian technology. They have gained wide experience with approaches like intensity-modulated radiotherapy (IMRT) for shaping the treatment beam to match the shape of the tumor, and RapidArc® radiotherapy, for delivering advanced treatments very quickly.
The new TrueBeam STx will continue to enable IMRT and RapidArc treatments, but with greater precision and higher dose delivery rates that make it possible to complete advanced treatments in less time. Dr. Wang is especially excited about the Gated RapidArc capabilities of the new TrueBeam STx machine, which use technology to monitor a patient's breathing and compensate for tumor motion during RapidArc treatments. "We anticipate using Gated RapidArc to deliver highly precise radiosurgical procedures for colorectal, liver, and lung tumors," Dr. Wang said.
Varian's TrueBeam was designed to treat tumors with unprecedented speed and accuracy. It features many technical innovations that dynamically synchronize imaging, patient positioning, motion management, and treatment delivery. With its High Intensity Mode, a TrueBeam machine can deliver very high doses quickly and accurately, more than twice as fast as earlier generations of technology. The TrueBeam STx is a high-end model optimized for radiosurgical applications, where very large doses are delivered in a single treatment or only a few sessions.
"This hospital has a long history of pioneering radiotherapy treatments for HCC," said Professor King-Jen Chang, Superintendent of Cheng Ching General Hospital. "We have great experience developed treating HCC over the past 14 years. This was one of the first hospitals in Taiwan to introduce RapidArc four years ago, and we have now become the first to offer TrueBeam treatments. Our multidisciplinary team will use our TrueBeam STx machine to treat all forms of cancer, especially those that involve tumor motion during treatment, like cancer of the liver and lung. We are pleased to be using the most state-of-the-art techniques for the benefit of our patients."
