Statins and pancreatic cancer risk: a nested case-control study.
Summary of "Statins and pancreatic cancer risk: a nested case-control study."
To investigate the relationship between statin use and pancreatic cancer risk.
A nested case-control study was conducted within the UK GPRD. Cases had a diagnosis of primary malignant neoplasia of the exocrine pancreas. Controls were matched with cases on general practice site, sex and year of birth. Exposure of interest was exposure to statins since entry into the GPRD until 1 year before the case diagnosis date. Conditional logistic regression analyses were used to generate ORs and 95% CI associated with statin use compared to non-use.
A total of 1,141 pancreatic cancer cases and 7,954 controls were identified. Any use of a statin since entry into the GPRD (excluding the year prior to diagnosis) was not associated with the risk of pancreatic cancer OR 0.93 (95% CI, 0.76-1.14). Neither dose nor duration of statin use affected pancreatic cancer risk. When dose and duration of statin use combined were assessed, no evidence of reduced risk was seen for long-term users of high-dose statins OR 0.71 (0.42-1.20). Statin type (simvastatin vs atorvastatin) was not associated with pancreatic cancer risk.
Statin use at doses for managing hypercholesterolaemia, in a UK population, was not associated with the risk of exocrine pancreatic cancer.

Medical and Biotech [MESH] Definitions
Studies designed to examine associations, commonly, hypothesized causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are CASE-CONTROL STUDIES; COHORT STUDIES; and CROSS-SECTIONAL STUDIES.
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions.

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).
Pancreatic Stellate Cells
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 synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
