CANCER DIGEST – June 8, 2014 – Scientists at the Mayo Clinic in Florida have developed a promising tool for detecting pancreatic cancer, which could lead to earlier treatment. In a feasibility study published in the journal Gastrointestinal Endoscopy, the researchers showed that an optical blood oxygen sensor attached to an endoscope is able to correctly identify pancreatic cancer 92 percent of the time and correctly rule out cancer 86 percent of the time. The device measures changes in blood flow in the tissues close to the pancreas. Tumors tend to increase blood flow in nearby tissues in order to extract oxygen needed to grow. The researchers tested the device in a group of 14 patients already diagnosed with pancreatic cancer and 10 patients without cancer. They are now conducting larger studies in the U.S. and Europe to see if their findings are confirmed. Currently 90 percent of pancreatic cancers are diagnosed at an advanced stage when there is no effective treatment.
