Characterizing the Pancreatic Cancer Proteome From Pancreatic Juice

Pancreatic cancer is very difficult to detect and treat, and patients with this cancer generally live fewer years than patients with other types of cancer. Part of the reason why pancreatic cancer is so hard to treat is because it is usually discovered when it is too advanced to be able to treat. The goal of this protocol is to find a way to detect pancreatic cancer earlier, when it is still treatable in order to improve the survival of patients.

The pancreas is a gland which produces digestive juices that mix with food in the intestines. Normal patients as well as patients with pancreatic cancer produce these juices. Other researchers have collected this fluid from very small numbers of patients and their results suggest that pancreatic fluid can be used to detect pancreatic cancer. One of the major issues with these results is that pancreatic fluid from only a very few number of patients has been collected and analyzed. In order to find out whether the pancreatic fluid can be used as a standard test for pancreatic cancer, the fluid from a greater number of patients needs to be analyzed. Also, of all the different chemicals in the pancreatic fluid, in this study we will try to figure out what the most important chemicals are in diagnosing pancreatic cancer.

• Eastern Cooperative Oncology Group(ECOG) performance status of 0-2. (All Cohorts)
• Negative urine pregnancy test at screening, if applicable. (All Cohorts)
• The patient must already have a completed, active consent for either endoscopic ultrasound(EUS) and/or endoscopic retrograde cholangiopancreatography (ERCP) at University of Alabama at Birmingham(UAB). (All Cohorts)

Group B:

• Male or female patients that have had chronic pancreatitis for at least 6 months.
• CT abdomen or MRI abdomen within the last 3 months demonstrating no suspicion of pancreatic adenocarcinoma.

Group C:
