Genentech Scientists Zero in on “Liquid Biopsies” as a Way to Replace Tissue Biopsies in Breast Cancer
Surgical pathologists could gain new tool to diagnose many types of cancers
It might soon be possible to determine the HER2 status of breast cancer patients from blood samples rather than tissue biopsies. If this new technology proves feasible, it would give surgical pathologists and medical laboratories a different, and possibly less complex, methodology to use when assessing a case of breast cancer.
In its report about the study, Medscape Medical News, wrote that “HER2 status derived from circulating tumor cells (CTCs) from breast cancer patients was generally concordant with that derived from tumor tissue” and that “CTCs could prove to be an alternative to biopsies for assessing tumor tissue for biomarker status.”
