Ter Haar, head of the therapy ultrasound team at the Institute of Cancer Research (ICR) Division of Radiotherapy and Imaging in London, and her colleagues will study how focused ultrasound may improve the local delivery of specially engineered viruses that target pancreatic cancer cells. They plan to use the most effective ultrasound techniques to shed light on tumor growth.
"Combining therapeutic ultrasound with new and current therapies for pancreatic cancer has exciting potential," she noted. "While a number of therapies exist for pancreatic cancer, it is clear that they are not as effective as in other cancer types because they cannot penetrate the tumor in the pancreas. We believe that ultrasound exposure of the pancreas will open up the tumor structure and allow better access for new treatment strategies, and also existing therapies, to the tumor cells. If this works as predicted, ultrasound will provide a new, minimally invasive technique for the enhancement of treatment of pancreatic cancer."
Pancreatic cancer patients have low survival rates. Less than 7% of people with pancreatic cancer in the U.K. will survive beyond five years. Evidence suggests that focused ultrasound can elicit an immune response to help the body fight the disease.
The team at ICR has developed a clinical ultrasound-guided focused ultrasound system, being the first to use this technique on cancer patients in clinical trials. The project is supported by Pancreatic Cancer UK and the Focused Ultrasound Foundation.
