To identify patients at risk for non-sentinel lymph nodes metastases, a nomogram was developed by the Breast Service of the Memorial Sloan-Kettering Cancer Center. The aim of this study was to assess the nomogram's predictive accuracy in a population of Italian breast cancer patients in our hospital.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>The system of calculation used as variables prognostic factors of breast cancer: pathologic size, tumor type and nuclear grade, lymphovascular invasion, multifocality, estrogen receptor status, method of detection of the sentinel lymph nodes metastases (frozen section, serial hematoxylin-eosin, routine hematoxylin-eosin, and immunohistochemistry), number of positive and number of negative sentinel lymph nodes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results and conclusions<\/jats:title>\n                    <jats:p>To measure the discrimination of the nomogram, a receiver-operating characteristic curve was construed, and the area under the curve was calculated.
