Study finds large gap in breast cancer treatment recommendations for patients aged 70 vs 69
Age-based heuristics can lead to large differences in breast cancer treatment based on small differences in chronologic age, according to a new analysis of more than 500,000 patient records. Patients aged 70 were nearly twice as likely to be passed over for standard-of-care radiation as those aged 69. There were no similar gaps between other age pairs. The study is among the first to demonstrate an age cutoff heuristic in oncology.

Cellular housekeeping process implicated in fatal neurological disorder
A new study from Washington University School of Medicine in St. Louis indicates that as patients age, Huntington’s disease gradually impairs autophagy, which eliminates waste from cells. This housekeeping is significant because a buildup of waste in a specific kind of neuron leads to such cells’ untimely deaths. The researchers also showed that enhancing the autophagy pathway in such neurons that were created from skin cells of Huntington’s patients protects those cells from dying.
