Axillary lymph node dissection in the case of sentinel lymph node micrometastatic invasion: evaluation of three predictive models

None of the tested models are sufficiently reliable for use in daily practice. The MSKCC nomogram showed the most encouraging results, especially for a threshold value of 7%, but this has not been validated in the literature. Complete axillary dissection should be performed in the case of micrometastatic SLN involvement until more data become available.
