If confirmed by larger series, a negative SNB may eliminate the need for ALND for select women with breast cancer.

Four of 51 women treated with observation alone after diagnosis of LCIS developed breast cancer. All were detected by screening at an early stage. LCIS appeared to be an incidental finding on biopsy of mammographic abnormalities. The policy of observation alone for the finding of LCIS spares women mastectomy. Furthermore, cancers that develop in follow-up are likely to be detected at an early stage and be amenable to curative therapy. Observation alone is appropriate treatment for women with LCIS.
