Background And Objectives:
The 1990s have established the contribution of multimodality therapy in the management of IIIb noninflammatory breast cancer (IIIb NIBC), by reducing the odds of recurrence and death.
Methods:
A total of 300 women with IIIb NIBC received a multimodality therapy. The treatment consisted of neoadjuvant chemotherapy [FAC (5-fluorouracil, Adriamycin, cyclophosphamide) regimen], radical (Halsted) mastectomy or modified (Patey mastectomy), postoperative radiotherapy, and adjuvant chemohormone therapy [FAC regimen + cyclophosphamide, 5-fluorouracil and methotrexate (CMF) regimen or Tamoxifen].
Results:
Complete or partial clinical response (CR or PR) after neoadjuvant chemotherapy was obtained in 83% patients. Ninety-nine patients (33%) survived 5 years without evidence of disease (NED). The uni- and multivariate analyses factors that had significant influence on the treatment results were: clinical response to neoadjuvant chemotherapy, pathological tumor size, and microscopical status of the axillary lymph nodes.
Conclusions:
We conclude that neoadjuvant FAC regimen chemotherapy is very effective in producing objective tumor regression and offers the benefit of radical mastectomy to patients with previously unresectable IIIb NIBC.
