Those who smoke and drink heavily may develop pancreatic cancer at an earlier age than those who don't, according to a study led by a University of Michigan Health System gastroenterologist.
In the study, published in the American Journal of Gastroenterology, heavy smokers with pancreatic cancer were diagnosed around age 62 and heavy drinkers at age 61 – almost a decade earlier than the average age of 72.
Smoking is a strong risk factor for pancreatic cancer and alcohol has been shown to cause oxidative damage to the pancreas, which sets the stage for the inflammatory pathways that can lead to cancer.
The findings only indicate these habits can lead to developing pancreatic cancer earlier in life.
The study of 811 pancreatic cancer patients from the multicenter, international database Pancreatic Cancer Collaborative Registry does not prove the habits caused cancer.
The study does make a step toward understanding at what age screening for pancreatic cancer should begin – once widespread screening is available.
"As screening programs are developed, an understanding of how personal features influence the age of presentation will be important to optimize the timing of those screenings," says lead study author and gastroenterologist Michelle Anderson, M.D., assistant professor of internal medicine at the University of Michigan Health System. Detecting pancreatic cancer early is difficult and contributes to the poor survival rates. By the time pancreatic cancer is diagnosed, it is frequently at an advanced stage and has spread to other organs.
Currently there are no tests available to easily find it in people who do not have symptoms. In the study, heavy smokers were defined as those who had more than a pack per day, and heavy drinking was measured at more than 39 grams a day, or about three average drinks per day.
Beer drinkers presented with pancreatic cancer earlier than those who drank other types of alcohol, such as wine or hard liquor although when adjusted for the amount of alcohol consumed, the type of alcohol did not affect the age of presentation.
The good news is that the harmful effects of heavy drinking and smoking can be resolved . After 10 years, former smokers and drinkers who quit their habits faced no extra risk of earlier diagnosis.
The registry used for the study gathers information on patients with pancreatic cancer and those at high-risk for developing pancreatic cancer.
Patient data was collected from University of Nebraska Medical Center, Omaha, Neb.; University of Genoa, Italy; Creighton University School of Medicine, Omaha, Neb.; University of Pittsburgh Medical Center; NorthShore University Health System, Evanston, Ill.; University of Chicago, Chicago, Ill.; University of Alabama at Birmingham, Ala.; and the University of Michigan Health System, Ann Arbor, Mich.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

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...
