[Radioguided occult lesion localization in breast cancer (ROLL): new techniques?].

Radioguided occult lesion localisation (ROLL) is a new technique which allows identification of non palpable breast lesion in breast cancer using, on the model of sentinel node procedure, injection of a radiotracer over the tumour lesion. With a gamma detection probe, it is then possible during surgery to identify in the same time the lesion and the sentinel lymph nodes. Compared with the wire-guided localisation (WGL), ROLL seems easier to achieve for radiologists, the excision procedure seems to be simpler with a good lesions resection in sano rate and a good cosmetic result.
