Locally advanced noninflammatory breast cancer represents 10% to 15% o
f all patients at diagnosis. The greatest risk for these patients is t
he development of distant metastases that lead to death. Local therapi
es, including surgery and radiation therapy, used in combination resul
t in improved locoregional control but have no significant effect on s
urvival. The institution of mulitmodality treatment regimens that incl
ude systemic chemotherapy has improved distant disease-free survival.
The appropriate sequencing of local and systemic treatment still is de
bated. Advantages to preoperative chemotherapy are assessment of in vi
vo chemosensitivity and the option for breast-conserving surgery in pa
tients with tumor down staging.
