Dr. Tripathy on Completing New Assays After Recurrence

Debu Tripathy, MD, professor of medicine and co-leader of the Women’s Cancer Program at the University of Southern California Norris Comprehensive Cancer Center, describes that when a patient has a recurrence the standard, if it is feasible, is to complete a new biopsy because the markers may have changed.

Tripathy explains that there will be a change in estrogen and progesterone receptors in approximately 10-20% of cases, with HER2 changes occurring in 5-10%.
