Benefit of novel drug in breast cancer seen in blood within weeks

A new study found that a novel histone deacetylase inhibitor drug, entinostat, can predict clinical benefit in breast cancer patients just days after treatment. The study showed that levels of protein lysine acetylation were related to clinical benefit, with patients who had elevated levels having a reduced risk of disease progression.
