The adjuvant therapy of postmenopausal, hormonereceptor positive breast cancer patients with aromatase inhibitors in ATAC, ABCSG 8/ ARNO 95 and IES trial revealed just a benefit in terms of disease-free survival, but not for over-all survival. Thus MA-17 trial is so far the only study which could demonstrate a survival benefit for node positive disease by "extended adjuvant" therapy with letrozole. Node- and receptorpositive, postmenopausal women show a higher benefit by anthracycline containing chemotherapy in combination with tamoxifen, than by endocrine therapy alone. But tamoxifen should given sequentially to chemotherapy (Intergroup 0100/ SWOG-8814 trial). Adjuvant chemotherapy with three cycles FEC followed by three cycles docetaxel reveals a survival benefit compared to six cycles FEC, especially in women older than 50 years (PACS 01 trial). Furthermore there is evolving evidence that dose-dense, interval shortened chemotherapy is superior to standard chemotherapy in adjuvant setting. The impaired survival of receptornegative, nodalpositive breast cancer patients seems to be converted to a survival improvement compared with receptorpositive patients by modern adjuvant cytotoxic regimens (metaanalysis CALGB 8541, 9344, 9741). In primary systemic chemotherapy survival is strongly associated with the rate of pathohistological complete remissions (NSABP B-27). The combination of cytotoxic drugs has no further influence on survival, but the sequential administration of taxane increases the rate of pCR. A difference in survival stratified by pCR and non-pCR in breast and positive nodal status could not be detected, so that the number of involved lymph nodes seems to be the strongest prognostic factor and is independent of tumor response in the breast The sentinel node biopsy is a safe and reliable method, but the rate of false negative findings depends on the pathohistological methods (NSABP B-32). The morbidity of this method is low compared with conventional axillary dissection in multicenter studies. Local tumor control is an important parameter which offers a significant survival benefit in all age cohorts.
