Group 1 - A new method for early and accurate detection of pancreatic cancer has been developed by researchers from the Fraunhofer Society in Germany, which is expected to significantly improve treatment outcomes [1] - The method is non-invasive and relies on the analysis of circulating tumor DNA (ctDNA) in the patient's blood, specifically through differential methylation analysis [1] - The process involves collecting a blood sample, isolating plasma, and extracting ctDNA released during cell death or degradation, allowing for the detection of specific pathological changes without the need for a biopsy [1] Group 2 - The detection method identifies biochemical modifications (methylation) at specific locations in the DNA, which differ between tumor DNA and healthy DNA [1] - High-throughput sequencing technology is utilized to recognize these differences, making the testing process more patient-friendly by allowing blood collection from areas like the elbow [1]
