Washington - Bna

A new blood test may hold promise as a means of early detection and diagnosis for often deadly pancreatic cancers. Reporting at the annual Gastrointestinal Cancers Symposium in San Francisco, researchers said the test, which measures levels of a protein known as PAM4, was able to identify two-thirds of patients who had pancreatic cancer at an early stage of their disease. Early pancreatic tumors typically fly under the radar, causing no symptoms and going undetected until they have spread. This partially accounts for the dismal prognosis faced by most people diagnosed with the illness. That''s why any means of spotting these cancers early would be critical. According to the researchers, PAM4 is a protein that is present in normal cells but is greatly elevated in cancerous ones. "When a person gets cancer, this protein spills into the bloodstream," explained Dr. Igor Astsaturov, an assistant professor of medical oncology at Fox Chase Cancer Center in Philadelphia. Astsaturov, who was not involved with the study, said the results were "certainly welcome news." When the researchers combined PAM4 with another test, CA19-9, which is already approved to monitor pancreatic cancer during treatment, the combination showed even stronger results and correctly identified 85 percent of patients with pancreatic ductal adenomcarcinoma (PDAC), by far the most common form of pancreatic cancer. More study of PAM4 may even point to possible targets for therapy, the authors stated. "For providers of care for patients with pancreatic cancer, hampered by their inability to readily detect these cancers in some cases, especially in earlier stages, this shows tremendous promise that blood-based assay can add to our ability to diagnose pancreatic cancer at an earlier stage, thereby impacting patients lives," said Dr. Morton S. Kahlenberg, a gastrointestinal cancers expert with the American Society of Clinical Oncology and moderator of a Tuesday press briefing on the findings. In previous research by the same group of authors, the PAM4 test was able to identify 82 percent of patients with PDAC. That study included about 80 participants, said study author David V. Gold, director of laboratory administration and a senior member with Garden State Cancer Center in Morris Plains, N.J. The current study updates those results by including blood samples from almost 300 people previously diagnosed with PDAC, 99 with other types of cancer, 126 with benign pancreatic disease and 79 healthy controls.
