Local Invasion of Pancreatic Cancer

2014-08-27 03:13:28 | BioPortfolio

Summary

Pancreatic cancer often spreads through local invasion into local structures, including fat, blood vessels, nerves, and nearby organs (stomach, duodenum, spleen, bile duct). Local microscopic invasion is associated with recurrence of pancreatic cancer after pancreatic resection, such that even if the original cancer is surgically removed, microscopic areas of cancer often remain. Data on the patterns of local invasion by pancreatic cancer have not been published. In this study, The investigators hope to investigate the frequency of the various methods of local invasion of pancreatic adenocarcinoma. This would help the investigators better understand how pancreatic cancer spreads, and determine what cancers are not resectable.

Description

Pancreatic cancer is the eighth most common malignancy, and the fifth leading cause of cancer-related death, in the United States. Unfortunately, patients often present late in the course of the disease. Accordingly, the 1- year survival rate is approximately 20%, and the 5-year survival rate is less than 4%. Even in patients with local disease who are surgical candidates, survival at five years remains only 10-25%. Staging for pancreatic adenocarcinoma typically utilizes the TNM classification, where "T" represents tumor size, "N" represents regional lymph node metastasis, and "M" represents distant metastasis. This type of staging can usually only be done after operative resection. Unfortunately, up to 25% of patients are found to be unresectable at the time of surgical exploration. This is most often due to local invasion or metastatic disease. Local microscopic invasion is associated with recurrence of pancreatic cancer after pancreatic resection. Comprehensive data on the patterns of local invasion by pancreatic cancer have not been published. We believe that it would be beneficial to investigate the frequency of the various methods of local invasion of pancreatic adenocarcinoma. A clearer understanding of the natural history of local invasion could potentially lead to a better determination of what constitutes unresectability.

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.

C-type lectins that restrict growth of bacteria in the intestinal epithelia and have bactericidal activity against gram-positive and gram-negative bacteria. They also regulate proliferation and differentiation of KERATINOCYTES following injury. Human pancreatitis-associated protein-1 (Reg3a) is overexpressed by pancreatic ACINAR CELLS in patients with CHRONIC PANCREATITIS. It is also highly expressed by pancreatic, bladder, and gastrointestinal cancer cells and may serve as a diagnostic biomarker.
