Watchful waiting strategy could save $1B in prostate cancer treatment costs

If the number of men with newly diagnosed prostate cancer who opted for watchful waiting increased from 10 percent to 50 percent, the resulting savings would surpass $1 billion, researchers estimated in a study published June 18 in Annals of Internal Medicine. The authors noted that new molecular imaging techniques could improve classification of low-risk candidates and set the stage for a more conservative approach than the active surveillance model.

FDG PET could predict treatment response for major depressives

Previous studies have pointed to treatment-specific imaging biomarkers for predicting response to therapy for patients with major depressive disorder (MDD), but brain imaging with FDG PET, particularly of the anterior insula, is going a step further to differentiate response to combined treatments, which could improve management of patients with the mood disorder, according to a study published June 12 in JAMA Psychiatry.
