[Conservative surgery for T2 > 3 cm, T3 N0 N1 M0 breast cancer after induction chemotherapy].
Induction chemotherapy (IC) provides in more than 20% of cases a complete shrinkage of the tumor. This down staging is a new challenge for the surgeons for breast conservative procedure. Although, IC has become the standard of care for breast cancer T2 > 3 cm T3 N0 N1 M0. No guidelines have devoted attention to the surgical problems due to this down staging after IC. Location and size of the tumor before IC have to be studied and outlined by the surgeon himself. During surgery, the residual tumor volume and how much mammary gland must be removed are very difficult to determine. The maximum volume of mammary gland to be removed after IC around the primary site of the tumor before IC is the volume which permits a good cosmetic reconstruction of the breast. After IC, in spite of an important downstaging, an axillary clearance must be done. For N0 patients, sentinel lymph node biopsy could be performed before IC. If the sentinel node is p N0, axillary clearance could be avoided.
