Several new studies that may help doctors tailor lung cancer treatment to the characteristics of individual patients and of their tumors are being presented at the 3rd European Lung Cancer Conference in Geneva.

A study evaluating off-label prescribing of medications in a primary care network in Canada suggests the practice is common, although it varies by medication, patient and physician characteristics, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

Loyola researchers are reporting surprising findings about a molecule that helps ramp up the immune system in some cases and suppress it in others. The finding eventually could lead to new drugs to regulate the immune system by, for example, revving it up to attack tumor cells or tamping it down to prevent the rejection of transplanted organs.

Expanding on previous research providing proof-of-principal that human stem cells can be genetically engineered into HIV-fighting cells, a team of UCLA researchers have now demonstrated that these cells can actually attack HIV-infected cells in a living organism.

A research team led by the University of South Florida Department of Psychiatry & Behavioral Neurosciences has found that a fragment of the amyloid precursor protein (APP) - known as sAPP-α and associated with Alzheimer's disease - appears to regulate its own production.

Combining two strategies designed to improve the results of cancer treatment - antiangiogenesis drugs and nanomedicines - may only be successful if the smallest nanomedicines are used.

A new report by American Cancer Society scientists says new data showing aspirin's potential role in reducing the risk of cancer death bring us considerably closer to the time when cancer prevention can be included in clinical guidelines for the use of aspirin in preventative care.
