Changes in blood flow and metabolism in locally advanced breast cancer treated with neoadjuvant chemotherapy.

Abstract

Although both resistant and responsive LABC tumors have an average decline in MRFDG over the course of chemotherapy, resistant tumors have an average increase in blood flow. Patients whose tumors fail to have a decline in blood flow after 2 mo of therapy have poorer disease-free and overall survival. Further investigations are needed to elucidate the tumor biology underlying these findings.
