Study Questions Accuracy of Lung Cancer Screens in Some Geographic Regions

A new analysis of published studies found that FDG-PET technology is less accurate in diagnosing lung cancer versus benign disease in regions where infections like histoplasmosis or tuberculosis are common. Misdiagnosis of lung lesions suspicious for cancer could lead to unnecessary tests and surgeries for patients, with additional potential complications and mortality.

Lung Cancer Test Less Effective in Areas Where Infectious Lung Disease is More Common

An analysis of 70 studies finds that use of the diagnostic imaging procedure of fludeoxyglucose F18 (FDG)-positron emission tomography (PET) combined with computed tomography (CT) may not reliably distinguish benign disease from lung cancer in populations with endemic (high prevalence) infectious lung disease compared with nonendemic regions, according to a study in the September 24 issue of JAMA.

Study Explores Drug Users’ Opinions on Genetic Testing

Published in the International Journal of Drug Policy, the study, “Perceptions of genetic testing and genomic medicine among drug users,” gauged drug users’ attitudes and understandings of genetics and genetic testing through six focus groups. The focus groups were segregated by race and ethnicity to increase participants’ comfort in talking about racial and ethnic issues. Over half of the participants (53%) reported having either HIV/AIDs or HCV, or a co-infection, and understood the potential value of genetic testing.
