Disparities in survival among black patients diagnosed with early-stage lung cancer are not seen when patients are recommended appropriate treatment, according to a report in the January issue of Archives of Surgery, one of the JAMA/Archives journals.

Researchers from Boston University School of Medicine (BUSM) have demonstrated that a recently discovered class of molecule called microRNA (miRNAs), regulate the gene expression changes in airway cells that occur with smoking and lung cancer.

Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer.

A research team from the University of California, San Diego School of Medicine has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells.

While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism. They say that "silencing" of a single gene in lung cancer led to a general impairment in genome-wide changes in cells, contributing to cancer development and progression.

Researchers say it appears that a food additive found in many processed foods may accelerate lung cancer growth, and increase the risk of lung cancer in people predisposed to the disease.

New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.

Individuals with particular variants of certain genes involved in metabolizing the most potent carcinogen found in cigarette smoke have an increased risk of developing lung cancer.

Blocking 2 cell signalling pathways leads to dramatic shrinkage of K-Ras-mutated tumors in animal model

Today begins the 32nd annual Great American Smokeout of 2008. While smoking is an addiction, and thus difficult or even near impossible to stop, there are many reasons to quit - and I shouldn't have to tell you them.

Patients operated on by surgeons who do not routinely remove cancer from the lungs may be at a higher risk for complications, according to a study conducted by researchers at Duke University Medical Center.

A study seeking possible cancer genes elucidated the mutations and the genetic pathways activated in the most common form of lung cancer – lung adenocarcinoma – and could lead to improved diagnosis and treatment, said the director of the Baylor College of Medicine Human Genome Sequencing Center that played a major role in the project led by the National Human Genome Research Institute.
