Therefore, there is a need for minimally-invasive diagnostic tools for detecting pancreatic cancer at an early stage, when curative surgery and also novel therapeutic approaches including precision medicine may be feasible. The "liquid biopsy" addresses these unmet clinical needs based on the concept that simple peripheral blood sampling and detection of circulating tumor DNA(ct DNA) could provide diagnostic information. In this review, we provide an overview of the current status of bloodbased tests for diagnosis of pancreatic cancer and the potential utility of ct DNA for precision medicine. We also discuss challenges that remain to be addressed in developing practical ct DNA-based liquid biopsy approaches for early diagnosis of pancreatic cancer.展开更多

But, with the advance of sequencing technologies for global genomic analysis, the landscape of genomic alterations in pancreatic cancer is becoming increasingly well understood. In this review, we summarize current knowledge of genomic alterations in 12 core signaling pathways or cellular processes in pancreatic ductal adenocarcinoma, which is the most common type of malignancy in the pancreas, including four commonly mutated genes and many other genes that are mutated at low frequencies. We also describe the potential implications of these genomic alterations for development of novel therapeutic approaches in the context of personalized medicine.展开更多
