Symptomatic Cholelithiasis Patients Have Increased Pancreatic Cancer Risk- A Population Based Study

Chi-Chih WangMing-Chang Tsai


Background :Pancreatic cancer is a fatal disease, andthe current risk factor survey is not suitable for sporadic pancreatic cancerthat lacks obvious family history orgenetic analysis data.The aim of the present study was to evaluate the roles of cholelithiasis and cholelithiasis treatmentson pancreatic cancer risk.Methods: Symptomatic adult patients with an index admission ofcholelithiasis diagnosis were selectedfrom one million random samples of National Health Insurance Research Database (NHIRD)obtained between January 2005 andDecember 2009. Exclusion criteria included pancreatic cancer, benign neoplasm or anomalies of the pancreas, orendoscopic sphincterotomy/endoscopic papillary balloon dilatation (ES/EPBD), cholecystectomy (CCY) before 2004. The control group was matched in a 1:1 ratio for sex, age,chronic pancreatitis and pancreatic cystic disease. The study group was divided into ES/EPBD, CCY, ES/EPBD&CCY, and no-intervention groupsfor subsequent pancreatic cancer evaluation.Results: Both the cholelithiasis group and the matched control group included 8,265 adult cases. The cholelithiasis group contained 86 (1.04%) cases of diagnosed pancreatic cancer and the control group contained8 (0.10%) cases (p<0.001). Exclu...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures. Follow the latest research on Glut1 deficiency with this feed.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Nodding Syndrome is a neurological and epileptiform disorder characterized by psychomotor, mental, and growth retardation. Discover the latest research on Nodding Syndrome here.

LRRK2 & Microtubules

Mutations in the LRRK2 gene are risk-factors for developing Parkinson’s disease (PD). LRRK2 mutations in PD have been shown to enhance its association with microtubules. Here is the latest research.
