INTRODUCTION: The neoadjuvant chemotherapy is increasingly being used in the treatment of patients with locally advanced breast cancer. We describe the hypothesis of the biological behaviour of breast cancer supporting the reason for the existence of this treatment. The improvement of neoadjuvant chemotherapy is being discussed as well as the advantages, disadvantages and problems of the treatment. THE AIM OF EXAMINATION: To study the results of neoadjuvant chemotherapy in patients with locally advanced breast cancer and the proportion of breast preserving surgery after the treatment.
METHODS: Sixty seven patients were given neoadjuvant chemotherapy treatment between 01.01.1999 and 12.31.2003. Twenty three patients were stage III A while 35 stage III B and 9 stage III C. 63% of the patients received CEF chemotherapy and 19% were given MMM. 18% were given neoadjuvant Taxotere + Carboplatin and 4% were given Taxotere + Farmorubicin chemotherapy.
RESULTS: After neoadjuvant chemotherapy 5 patients had SD (stable disease), 32 patients had MR (minor response) and in 28 cases patients had PR (partial response). Two patients showed pCR (complete pathologic response). Twenty patients (30%) had breast preserving surgery.
CONCLUSIONS: On the basis of our own experience neoadjuvant therapy is justified in patients with locally advanced breast cancer as they have bigger chance for breast preserving surgery. If mastectomy and axillary block dissection has to be carried out they are easier to perform. Taxans must be introduced for neoadjuvant treatment in order to improve our results. A longer follow-up is necessary before drawing final conclusions.
