Association Of Chronic Pancreatitis Research Articles

Prior History of Pancreatitis Accelerates the Development of Pancreatic Adenocarcinoma.

Presentation of pancreatic adenocarcinoma (PC) as acute pancreatitis (AP), association of chronic pancreatitis (CP) with PC, and role of inflammation in PC carcinogenesis are well recognized. We hypothesized that inflammatory changes associated with remote history of AP (≥2 years before PC diagnosis) would result in earlier age of PC diagnosis. We evaluated PC patients prospectively enrolled in the Pancreatic Adenocarcinoma Gene Environment Risk (PAGER) study at the University of Pittsburgh for history of pancreatitis and reviewed relevant medical records and imaging studies. Univariate and multivariable linear regression analyses evaluated the relationship between PC and remote history of AP. Among 790 patients with histologically confirmed PC, 114 (14.4%) had a history of pancreatitis (AP within 2 years of PC diagnosis in 69 [8.7%], remote history of AP in 28 [3.5%], CP in 4 [0.5%], and unknown duration of pancreatitis in 13 [1.6%]). After controlling for age, sex, body mass index, smoking, alcohol history, and diabetic status at diagnosis, patients with a remote history of AP were diagnosed on average 4.7 years earlier with PC when compared with PC patients without history of AP (P < 0.035). Remote history of AP may accelerate carcinogenesis in PC.

The most important advances in chronic pancreatitis concern its etiopathogenesis, nutritional aspects, and improvements in diagnostic techniques and some treatment options. In the etiopathogenesis of this disease, the importance of smoking and its association with alcohol have been confirmed. Exocrine pancreatic insufficiency (EPI) secondary to chronic pancreatitis is associated with bone metabolism alterations (osteopenia and osteoporosis), a reduction in liposoluble vitamins and alterations in essential amino acid levels. Endoscopic ultrasound has been confirmed as the most highly developed technique for the diagnosis of chronic pancreatitis, especially due to new image optimization technologies. Breath tests for the diagnosis of EPI continue to be developed (optimization of the C-13 mixed triglyceride test and the development of a new test based on C-13-labelled bicarbonate determination). Modest results in pain treatment have been achieved with the use of antioxidants, pancreatic enzymes and/or intravenous secretin. The association of chronic pancreatitis with pancreatic cancer requires strict follow-up, especially in patients with inflammatory masses in the context of chronic pancreatitis.
