PET scans show biomarkers could spare some breast cancer patients from chemotherapy
In an effort to further individualize therapy and avoid over-treating patients, researchers at the Johns Hopkins Kimmel Cancer Center report a new study using PET scans has identified a biomarker that may accurately predict which patients with one type of HER2-positive breast cancer might best benefit from standalone HER2-targeted agents, without the need for standard chemotherapy.
