Sentinel node biopsy has been shown to be as effective as a standard level I& II axillary dissection.Even when it has become a standard of practice in many centers,surgeons need to evaluate their false negative, concordance and identification rates by performing sentinel node biopsy together with level I & II axillary dissection in at least 20 cases.Many studies have shown that sentinel node biopsy provides for a more thorough pathologic evaluation of the sentinel node leading to better identification of axillary metastasis. Sentinel node biopsy can become part the surgeons armamentarium in the staging of invasive breast cancer, in particular those with clinically negative axillary nodes, even when axillary dissection is performed. Sentinel node biopsy maybe even more important in patients with DCIS were presently axillary dissection is not indicated,with a risk of understaging the disease in a percentage of patients with DCIS.In DCIS with microinvasion a sentinel node biopsy may adequately identify axillary metastasis without the need for standard level I and II axillary dissection.
