Radioguided breast lesion localisation with I-125 seeds


Improvements in diagnostic imaging and routine breast screening programmes have increased the detection of small impalpable breast lesions. At least half of malignant breast lesions requiring surgical removal are asymptomatic and are identified by mammography or ultrasound. These tumours are also difficult to identify by palpation during surgery and the surgeon needs to be guided to the location of the tumour.

We have set out to introduce a new technique, ROLLIS (radioguided occult lesion localisation using I-125 seeds), to assist with localising impalpable breast lesions. A multidisciplinary ROLLIS Working Group has been formed to steer the introduction of the technique to Australia for the first time. In this pilot study, patients with confirmed breast cancer will receive ROLLIS in addition to standard hook-wire localization.

Why my research is important

Staff will gain the necessary expertise to use ROLLIS accurately and safely safely without the hook-wire guide to localise and remove impalpable breast cancers. This pilot study is designed to prelude a multi-centre, randomised controlled clinical trial. If successful, ROLLIS has the potential to improve surgical outcomes for hundreds of West Australian women every year.
