Tamoxifen has been the endocrine agent of choice for adjuvant hormonal therapy for early breast cancer since approval in 1986. Five years of tamoxifen treatment produced a significant reduction in recurrence and death over more than 10 years of follow-up in women with estrogen receptor-positive (ER+) breast cancer. ⋯ This review provides a synopsis of the most recent trial results and a discussion of remaining areas of uncertainties. Although currently tamoxifen still remains a valid option, increasing evidence from the new AI adjuvant trials suggests that optimised adjuvant endocrine treatment should incorporate an AI either as initial or as sequential therapy.

Intraductal carcinoma of the breast (DCIS), by definition, cannot give axillary metastases. Axillary dissection is therefore not indicated. The role of the sentinel lymph node (SLN) biopsy in the management of DCIS has not yet been established. ⋯ SLNB should be considered in case of DCIS where there exists a strong doubt of invasion at the definitive histology, such as large solid tumours or diffuse or pluricentric microcalcifications undergoing mastectomy. Moreover, if the trend is statistically confirmed with a wider population, large comedo-DCIS, presenting superior risk of SLNs metastasis, could be scheduled for SLNB. If the SLN is micrometastatic complete axillary dissection is not unavoidable.
