[Breast-conserving surgery in breast cancer]

Breast-conserving surgery is the treatment of choice for the breast cancer T3 cm. The local recurrence is a problem of diagnosis and consequent treatment. We enrolled, from 1987 to 2004, 1504 breast cancer. In 803 (53.4%) tumor with T3 cm we performed conserving surgery. The sentinel lymph node (SN) technique induce to limit the axillary dissection in patients T1a-b to the SN only if non metastatic and located to the first level, the dissection of the 1st level of the axilla in patients T1c-T23 cm and SN negative, complete axillary dissection in patients with metastatic SN or located to the 2nd level. Our percentage of local recurrence in the follow-up was 3.5% at 5 years and 6% at 10 years.
