Recent advances in breast cancer (the Twenty-fourth San Antonio Breast Cancer Symposium, December, 2001).

Abstract
This paper reviews the Twenty-fourth Annual San Antonio Breast Cancer Symposium. The preliminary results of the ATAC study have shown that Arimidex is superior to tamoxifen in postmenopausal women with ER-positive early breast cancer in terms of DFS, adverse effects and prevention of contralateral breast cancer. However, longer follow up is required to assess the drug safety regarding bone mineral density and cognitive function. Letrozole seems to be superior to tamoxifen as a first-line therapy in ER-positive advanced breast cancer in postmenopausal women. Although the incidence of acute myeloid leukaemia is significantly increased (cumulative incidence at 5 years = 1.1%) in breast cancer patients receiving cyclophosphamide and anthracyclines, the risk of this complication is easily outweighed by the benefits of chemotherapy. Adjuvant clodronate was found to be associated with a significant reduction in the incidence of bone metastases during the treatment period. A randomised trial comparing axillary dissection and axillary radiotherapy (RT) for early breast cancer reported no significant difference in survival at 15 years. However, axillary recurrence was significantly increased in the RT group. hTERT protein expression by IHC was found to correlate significantly with breast cancer-specific survival. There is no evidence to support the use of IHC of the sentinel node in routine clinical practice. LCIS is currently considered as a non-obligate precursor to breast cancer rather than just a risk factor.
