Researchers develop new method to test for lung cancer

03.04.2008
Researchers from Boston University School of Medicine have developed a new “clinicogenomic model” to accurately test for lung cancer. The model combines a specific gene expression for lung cancer as well as clinical risk factors. These findings currently appear on-line in the journal Cancer Prevention Research.

Lung cancer is the leading cause of cancer death in the United States and the world, with more than one million deaths worldwide annually. Eighty-five to 90 percent of subjects with lung cancer in the United States are current or former smokers with 10 to 20 percent of heavy smokers developing this disease.

A previous study by the same researchers reported a gene expression biomarker capable of distinguishing cytologically normal large airway epithelial cells from smokers with and without lung cancer. However, the biomarker has limited sensitivity depending on the stage and the location of the cancer.

Studying current and former smokers undergoing bronchoscopies for suspicion of lung cancer, the researchers compared the likelihood of the subjects having lung cancer using the biomarker, the clinical risk factors and a combination of the two -- clinicogenomic model. They found patients using the clinicogenomic model had increased sensitivity, specificity, positive value and negative predictive value of their cancer compared to the other methods.

“Our data suggests that the clinicogenomic model might serve to identify patients who would benefit from further invasive testing, thereby expediting the diagnosis and treatment for their malignancy,” said senior author Avrum Spira, MD, an assistant professor of medicine and pathology at Boston University School of Medicine.

According to the researchers, it is hoped this prediction model will expedite more invasive testing and appropriate therapies for smokers with lung cancer as well as reduce invasive diagnostic procedures for individuals without lung cancer.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

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...

Im Focus: Self-illuminating pixels for a new display generation

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...

Im Focus: Entangled atoms shine in unison

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...
