Circulating Cell-free Tumor DNA(ctDNA) in Pancreatic Cancer

2016-10-18 02:08:21 | BioPortfolio


The aim of the study is to evaluate whether peripheral circulating cell-free tumor DNA(ctDNA) can help early screening of pancreatic cancer recurrence or not. And we are also planning to evaluate correlation between ctDNA with clinical outcome of pancreatic cancer.


In the formation and growth of a primary tumor, cells can released into the bloodstream. There are many researches for these circulating tumor cells(CTC) And recently circulating cell-free tumor DNA(ctDNA) released from apoptotic or necrotic tumor cells has developed. At one report which checked ctDNA level after operation of colon cancer patients, they suggested that ctDNA could show recurrence of cancer several months earlier than the conventional follow up imaging. And several reports suggested that ctDNA can invade host cell and change host cell biology, which can evoke cancer metastasis.

So in this study, we will collect ctDNA of pancreatic cancer patients who underwent operation, and will evaluate whether peripheral ctDNA can help early screening of cancer recurrence. And we will study about genomic signature of ctDNA to evaluate relationship between ctDNA and clinical outcome of cancer patients.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).

Star-shaped, myofibroblast-like cells located in the periacinar, perivascular, and periductal regions of the EXOCRINE PANCREAS. They play a key role in the pathobiology of FIBROSIS; PANCREATITIS; and PANCREATIC CANCER.

A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.

Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.

A pancreatic trypsin inhibitor common to all mammals. It is secreted with the zymogens into the pancreatic juice. It is a protein composed of 56 amino acid residues and is different in amino acid composition and physiological activity from the Kunitz bovine pancreatic trypsin inhibitor (APROTININ).
