Abstract

The 7th edition of the American Joint Committee on Cancer (AJCC) classifies a locally advanced breast cancer (LABC) as those included in III stadium (IIIA, IIIB, and IIIC) represented by tumors >5 cm (T3) or those associated with chest wall (T4A), skin (T4B), or both (T4c) involvement or the presence of fixed or matted axillary lymph nodes (N2/N3) of one or more lymphatic drainage chains (axillary, supraclavicular, or internal mammary) (T4D) (inflammatory carcinoma).

It has been demonstrated that there is a higher incidence of locally advanced carcinomas in European countries when compared to the USA. CrossRefGoogle Scholar

A retrospective study supporting that patients submitted to neo-adjuvant QT, that SLNB is feasible in the group with clinically positive axilla that presented complete clinical response. Overall 5-year survival was the same when compared to the group with previously negative axilla. Patients with positive axilla, who were negative on chemotherapy and submitted to sole SLNB, presented axillary recurrence smaller than 1% in 5 years. CrossRefGoogle Scholar

Axillary ultrasonography (with or without biopsy) and SLNB represent the safe and feasible staging and may be useful to plan surgical, radiotherapy, and chemotherapeutic approaches. The specificity and ability to detect impairment ranged from 70-96% and 50-73%, respectively. The specificity increased considerably with percutaneous SLN biopsies. CrossRefGoogle Scholar

J Clin Oncol. 2008;26(6):778–85. NSABP protocols B18 and B27 supported that neo-adjuvant QT is equivalent to adjuvant. In Protocol B18, women <50 years of age, treated with neo-adjuvant QT presented higher SLD and SG, trending towards statistical significance. RH 0.85. p 0.09 w / SLD and 0.06 w / wG). At B 27, the addition of taxane to the AC plan considerably increased the achievement of complete biological response (RpC). (26.13%, p = 0.0001). In both studies, patients who achieved RpC continue to present better SLD and SG, compared to those who did not. CrossRefGoogle Scholar
