MedicalResearch.com: What is the background for this study?
Response: Our prior research consistently found a significant inverse association between circulating levels of soluble receptor for advanced glycation end products (sRAGE), an anti-inflammatory factor, and risk of pancreatic cancer. It has also been found that sRAGE levels or RAGE signaling are modulated by anti-hypertensive (anti-HT) medications, including angiotensin-converting-enzyme inhibitors (ACEi), β-blockers, and calcium channel blockers (CCBs). These medications have been shown in prior pre-clinical or experimental research to either increase sRAGE concentrations, decrease formation of advanced glycation end-products (AGEs), or dampen pro-inflammatory receptor for AGE (RAGE) signaling pathway. We therefore hypothesized that there would be an inverse association between use of anti-HT medications and risk of developing pancreatic cancer.
Pancreatic cancer is a major public health concern in the United States, as it is the 4th leading cause of cancer-related mortality with an estimated of 43,090 deaths in 2017. Pancreatic cancer typically occurs in elderly individuals who also have chronic comorbid medical conditions, such as hypertension. Anti-HT medication use in individuals ≥ 18 years old has increased from 63.5% in 2001-2002 to 77.3% in 2009-2010, according to the National Health and Nutrition Examination Survey in the U.S. Therefore, it is of great public health significance to address the potential association between anti-HT medication use and risk of pancreatic cancer in the general population.
