GPS technology improves the accuracy of radiotherapy for pancreatic tumors

Release date: 2009-08-20



New research indicates hopeful use of Global Positioning System (GPS) technology to track pancreatic tumor metastasis.
Calypso Medical Technologies Inc. announced data from a clinic-sponsored survey at the University of Pennsylvania that showed the utility of the Calypso system to track pancreatic tumors. The results of the survey were presented to the 51st Annual Meeting of American Medical Physicists, which was held in Anaheim, USA, from July 26th to 30th, 2009.
Dr. James Metz, a health system in Pennsylvania, said: "The Calypso system has successfully tracked pancreatic tumors, which makes us feel very excited because our time response characteristics indicate that Calypso's GPS technology can be applied to other Prospects in the field of anatomy."
Calypso technology provides accurate, continuous real-time information on the location of tumors by implanting diseased micro-transponders and performing radiation therapy in vitro. After understanding the precise location of the tumor, the tumor can be accurately treated with radiation.
The US Food and Drug Administration has approved the system (FDA) for prostate cancer and prostate bed radiation therapy; in addition, another goal of the technology is for a wide range of applications in various parts of the body.
Pancreatic cancer is one of the most deadly cancers, according to the American Cancer Society (ACS), which affects more than 42,000 Americans each year. In addition, more than 35,000 people will die of pancreatic cancer in the United States alone in 2009. The National Cancer Institute lists a 1-year survival rate of 24% and a 5-year survival rate of only 1%.
The Calypso system provides real-time tracking for tumor radiation therapy. Tracking tumor movements is essential for radiation therapy because internal organ movements in severe patients may increase the chance of radiation to surrounding healthy tissue.
