In this study, "optical biomarkers," which combine a special microscope with a broad band white light source, was able to sort out three characteristics of the cell nucleus that signaled a person was at risk for cancer.
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.
"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."
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.
Barrett's esophagus involves changes to the esophageal lining, which sometimes continues into cancer. People with long term gastroesophageal reflux disease (GERD) are at particular risk.
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.
Blood Test Shows Promise in Spotting Pancreatic Cancers Early
Reporting Tuesday 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.
"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 Nike Vapormax Triple Black 3.0 add to our ability to diagnose pancreatic cancer at an Nike Air Vapormax Flyknit Men's Running Shoe
Right now, doctors use endoscopy and standard biopsies along the length of the esophagus to monitor for cancer However, this isn't able to sort out tiny changes that separate those at very high risk for cancer from those at much lesser risk.
A second abstract being presented at the symposium also demonstrated the potential utility of these types of diagnostic "biomarkers," this time in identifying which people with Barrett's esophagus are more likely to develop esophageal cancer.
By Amanda GardnerTUESDAY, Jan. 17 (HealthDay News) A new blood test may hold promise as a means of early detection and diagnosis for often deadly pancreatic cancers.
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.
Meanwhile, the test had relatively few false positives, mistakenly identifying only 19 percent of benign pancreatic disease patients and 23 percent of chronic pancreatitis patients.
The tests did not appear to be helpful in finding other forms of pancreatic cancer, the researchers stressed.

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.
That's why any means of spotting these cancers Nike Vapormax High
