Complementarity of Blue Dye and Isotope in Sentinel Node Localization for Breast Cancer: Univariate and Multivariate Analysis of 966 Procedures

Background: The hypothesis that sentinel lymph node (SLN) mapping in breast cancer patients is optimized by combining blue dye and isotope is reasonable and intuitive. Despite this, few studies examine in detail the factors contributing to the success of these techniques, either individually or in combination.
