PURPOSE: Few studies have evaluated the chemopreventive effect of aspirin on the cancer risk in elderly women. We examined associations between frequency, dose, and duration of aspirin use with incidence of 719 aspirin-sensitive cancers (cancers of colon, pancreas, breast, and ovaries) in the Iowa Women's Health Study (IWHS), a prospective cohort of women over 70 years old. METHODS: Aspirin frequency, dose, and duration were self-reported in the 2004 IWHS questionnaire...

Non-steroidal anti-inflammatory drugs (NSAIDs), especially aspirin, have been associated with lowered cancer incidence and mortality. We examined overall cancer mortality and mortality from specific cancer sites among the 80,144 men in the Finnish Prostate Cancer Screening Trial. Information on prescription drug use was acquired from the national drug reimbursement database. Over-the-counter use information was gathered by a questionnaire. Hazard ratios (HR) and 95% confidence intervals (CI) by prescription and over-the-counter NSAID use for overall and specific cancer deaths were calculated using Cox regression...

We have entered a transformative period in cancer prevention (including early detection). Remarkable progress in precision medicine and immune-oncology, driven by extraordinary recent advances in genome-wide sequencing, big-data analytics, blood-based technologies, and deep understanding of the tumor immune microenvironment (TME), has provided unprecedented possibilities to study the biology of premalignancy. The pace of research and discovery in precision medicine and immunoprevention has been astonishing and includes the following clinical firsts reported in 2015: driver mutations detected in circulating cell-free DNA in patients with premalignant lesions (lung); clonal hematopoiesis shown to be a premalignant state; molecular selection in chemoprevention randomized controlled trial (RCT; oral); striking efficacy in RCT of combination chemoprevention targeting signaling pathway alterations mechanistically linked to germline mutation (duodenum); molecular markers for early detection validated for lung cancer and showing promise for pancreatic, liver, and ovarian cancer...

OBJECTIVE: Investigate the therapeutic effect of regional arterial infusion (RAI) with Aspirin-Triggered Lipoxin A4 (ATL) in experimental severe acute pancreatitis (SAP) in rats. MATERIALS AND METHODS: SAP was induced by injection of 5% sodium taurocholate into the pancreatic duct. Rats with SAP were treated with ATL (the ATL group) or physiological saline (the SAP group) infused via the left gastric artery 30 min after injection of sodium taurocholate. The sham group was subjected to the same surgical procedure, though without induction of SAP...

BACKGROUND: Pancreas-cancer prognosis is dismal, with 5-year survival less than 5%. Significant relationships between aspirin use and decreased pancreas-cancer incidence and mortality have been shown in four of 13 studies. METHODS: To evaluate further a possible association between aspirin use and risk of pancreatic cancer, we used data from a population-based Connecticut study conducted from January 2005 to August 2009, of 362 pancreas-cancer cases frequency matched to 690 randomly sampled controls...

Lysis of(14)C-labeledStaph. aureus by human blood leukocyte lysates, by extracts of rabbit small intestines and pancreas, and by the "cocktail" of enzymes (containing trypsin, lysolecithin, and lysozyme) is strongly inhibited by anionic polyelectrolytes (e.g., heparin, chondroitin sulfate, liquoid (polyanethole sulfonic acid), and DNA). Most of the lytic agents employed were inhibited by cationic polyelectrolytes (e.g., histone, protamin sulfate and polylysin), as well as by gold thiomalate, normal human serum, synovial fluids obtained from patients with knee-joint trauma, extracts of coffee, tea, and cocoa, Ultracorten- and Dexamethasone...

We investigated short (6 months) and long (12 months) term inhibitory effects of low (200 ppm) and high (400 ppm) dosages of acetylsalicylic acid (aspirin) on exocrine pancreatic carcinogenesis. It is known that exocrine pancreatic carcinogenesis can be detected by the presence of atypical acinar cell foci (AACF) in pancreas. We investigated possible inhibitory effects of acetylsalicylic acid in an azaserine-treated rat model. AACF were produced in rats by injection with azaserine according to previous studies...

Nitric oxide-releasing aspirin (NO-aspirin) represents a novel class of promising chemopreventive agents. Unlike conventional nonsteroidal anti-inflammatory drugs, NO-aspirin seems to be free of adverse effects while retaining the beneficial activities of its parent compound. The effect of NO-aspirin on pancreatic carcinogenesis was investigated by assessing the development of precursor pancreatic lesions and adenocarcinomas in Kras(G12D/+) transgenic mice that recapitulate human pancreatic cancer progression...

Butyrylcholinesterase (BChE) is synthesized in the liver and found in high concentrations in blood plasma, liver, heart, pancreas, vascular endothelium, skin, brain white matter, smooth muscle cells and adipocytes. BChE is a non specific enzyme that hydrolyzes different choline esters (succinylcholine, mivacurium) and many other drugs such as aspirin, cocaine and procaine. The enzyme is also considered as a bioscavenger due to its ability to neutralize the toxic effects of organophosphorus compounds (nervous system fs agents) such as soman...

NO-aspirin (NO-ASA), consisting of aspirin and a nitric oxide-releasing group, is safer than aspirin and effective in colon cancer prevention. Here, we examined the mechanism of action of NO-ASA by focusing primarily on its effects on the cell cycle. NO-ASA reduced the growth of several cell lines from colon, pancreas, skin, cervix and breast cancer much more potently than aspirin, with 24-h IC(50) values of 133-268 µM, while those of ASA were >1,000 µM. NO-ASA elevated the intracellular levels of reactive oxygen species, generating a state of oxidative stress...

Pancreatic cancer (PC) continues to have a poor prognosis. New epidemiological trials have suggested that there may be protective factors, such as aspirin or oleic acid intake. The main diagnostic tool for PC is endoscopic ultrasound (EUS), and new EUS-related technologies have appeared, such as quantitative elastography (strain ratio and hue histogram analysis), intravenous contrasts, and the new procore needles to help in the differential diagnosis with other diseases (mainly chronic pancreatitis). In the next few years, intratumoral confocal endomicroscopy will be used for the diagnosis of PC and cystic tumors, by inserting a miniprobe inside the 19G needle of the echoendoscope...

PURPOSE OF REVIEW: Pancreas graft thrombosis remains one of the most common reasons for pancreas transplant loss. Patients with a history of thrombotic events should be identified and evaluated for thrombophilia to identify transplant candidates at highest risk. RECENT FINDINGS: Early after transplant, vascular thrombosis is multifactorial, but beyond 2 weeks, inflammation or acute rejection predominate as the cause of thrombosis. Most pancreas transplant centers utilize some form of anticoagulation following transplantation...

In the present study, we aimed to investigate the role of aspirin in preventing type 2 diabetes in rats. At 5 days old, rat pups were divided into four groups. Group I pups received citrate buffer solution and served as control; group II was treated only with streptozotocin (80 mg/kg i.p.) and served as the diabetic control; groups III and IV were treated with aspirin (10 mg/kg/day p.o.) for 1 and 2 months, respectively, after streptozotocin treatment and served as treated groups. During weeks 8 and 10, blood samples were collected from all animals and fasting blood sugar, fasting insulin, insulin resistance and insulin sensitivity were determined...

Aspirin is chemopreventive against colon and probably other cancers, but this effect is relatively weak and its chronic administration to humans is associated with significant side effects. Because of these limitations, extensive effort has been exerted to improve the pharmacological properties of aspirin. We have determined the anticancer activity and mechanisms of action of the novel para positional isomer of phosphoaspirin [P-ASA; MDC-43; 4-((diethoxyphosphoryloxy)methyl)phenyl 2-acetoxybenzoate]. P-ASA inhibited the growth of 10 human cancer cell lines originating from colon, lung, liver, pancreas and breast, at least 18- to 144-fold more potently than conventional aspirin...

Clopidogrel is a potent inhibitor of platelet aggregation and has been used as an alternative, or as an adjunct to aspirin in reducing the risk of thrombosis. A 34-year-old uremic type 1 male diabetic patient who underwent simultaneous kidney-pancreas transplantation was given clopidogrel as he was allergic to aspirin. He developed polyarthralgia one week later, followed in a few days by symmetrical migratory polyarthritis, which resolved completely on withdrawing the drug. The implications to clinical management in a transplant setting are discussed...
