A new study finds tobacco may act as an environmental trigger for patients with an inherited genetic predisposition to pancreatic cancer. The authors of the report say the findings underscore the importance of strongly counseling patients with a family history of pancreatic cancer to avoid smoking. The study will be published in the December 15, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this study will be available via the CANCER News Room upon online publication.
Pancreatic cancer is rare and poorly studied. What is known is that pancreatic cancer is aggressive, with a five-year survival rate of only 4 percent. A small percentage of patients with pancreatic cancer have first-degree relatives with pancreatic cancer. Smoking has been identified as the single most important risk factor in familial pancreatic cancer. Despite genetic characterization of other hereditary cancers, the genetic component of pancreatic cancer remains a mystery. With such little known about what is now called familial pancreatic adenocarcinoma (FPAC), researchers led by Ted A. James, M.D. of the Roswell Park Cancer Institute in Buffalo, New York investigated the clinical course and outcome of FPAC compared to sporadic pancreatic cancer.
Retrospective review of 826 patients with pancreatic cancer found 30 had the familial form (3.6 percent). Earlier age at diagnosis and a smoking history were marked features among the familial group. The mean age of diagnosis was younger in the hereditary cohort than among those with the sporadic form (57.1 years old versus 61 years old), and more FPAC patients were diagnosed before the age of 50 (36.7 percent versus 18.3 percent). Moreover, patients with FPAC were more likely to smoke than those who had sporadic pancreatic cancer (87 percent versus 66 percent).

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
