Primary Outcome Measures:
  • Clinical objective and pathological responses to chemotherapy [ Time Frame: 8 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • tumor concordance measurement among physical, radiologic and pathologic exams [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
    tumor concordance measurement among pre-operative physical examination (PE), mammography (MG), ultrasound (US), breast MRI and post-operative pathologic measurement concordance with PE, MG, US and MRI

  • security of oncoplastic surgery after neoadjuvant chemotherapy [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]
    use and security of oncoplastic surgery after neoadjuvant chemotherapy

  • overall actuarial survival [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]

Women with invasive breast cancer; clinical stage III, condition to receive neoadjuvant chemotherapy based in doxorubicin/ cyclophosphamide and paclitaxel
Drug: doxorubicin
4 cycles AC: doxorubicin 60mg/m2
Other Name: clinical and radiologic response
Drug: cyclophosphamide
4 cycles AC: cyclophosphamide 600mg/m2
Other Name: clinical and radiologic response
Drug: paclitaxel
4 cycles T: paclitaxel 175mg/m2 after 4 AC

Surgery D30 after chemotherapy
Other Names:
  • clinical, radiologic and pathologic response
  • neoadjuvant chemotherapy
  • conservative breast surgery
  • oncoplastic surgery

Detailed Description:

Locally advanced breast cancer is a common condition in development countries. Neoadjuvant chemotherapy gives the opportunity to identify genetic signatures associated with objective clinical and pathological complete responses.

Patients will receive doxorubicin/cyclophosphamide with paclitaxel. Tumor samples collected before and after chemotherapy will be analyzed.
