The Efficacy of Sentimag in Detection of Sentinel Node Biopsy

The aim of this study is to evaluate the Sentimag/Sienna+ System (Sentimag®) in clinical routine practice. On the one hand this allows evaluation of the equivalence of the two techniques. On the other hand this ensures that patients do not experience any possible disadvantages by participating. The hypothesis behind this evaluation is that Sentimag is as efficient as conventional sentinel node mapping. The programme will compare the Sentimag® with the conventional sentinel lymph node detection with radioactive tracer combined with blue dye (in centres using the combined technique) and thereby determine whether the new technique is equivalent to the standard technique for SLNB.
