Summary
Brief summary (as posted)
After breast cancer (BC) screening was introduced for all Swedish women in 1989-90 the number of early invasive BC, clin N0 rose dramatically. For these BC it was known that only 10 % or less was N+ after axillary dissection and the morbidity for axillary surgery was substantial. Omitting axillary dissection in a randomized trial was ruled out because of anticipated few events. A national cohort was decided for invasive unifocal BC, histological grade 1 or 2, T=max 10mm, free margins, clin node neg. No axillary dissection should be undertaken. This was before the Sentinel Node era. Adjuvant treatment could be given according to regional guidelines for early breast cancer. Not uniform concerning postoperative radiotherapy and antihormonal treatment. Follow-up was clinical the first 5 years with mammography and then by hospital records and national Death register. Primary aim: Number of axillary recurrence and BC specific survival.
