How to Localize Breast Masses by Wire and Marker?


Radiologist Associate Professor of Radiology. Tehran University of Medical Sciences Cancer Institute, Tehran-Iran



With the advent of screening methods, most of the breast cancers are diagnosed when they are small and can be treated using breast-conserving surgery. Since these tumors are non-palpable, they require a localization step that helps the surgeon to decide which tissue needs to be removed. The most popular localization technique is a wire placed into the tumor              before   surgery,   usually   using ultrasound        or                    mammography              guidance. Afterwards, the surgeon removes the tissue around the wire tip. However, this technique has several disadvantages: It can cause the patient discomfort, requires a radiologist or another professional specialized in breast diagnostics to perform the procedure shortly before surgery, and 15–20% of patients need a second surgery to completely remove the tumor. Therefore, new techniques have been developed but most of them have not yet been examined in large, prospective, multicenter studies. Marker insertion within a tumor is performed to make sure that it will not be lost after biopsy or NACT and if too small or no tumor residue is left, then the marker in its bed can be localized by wire.
This will be a hands on workshop that will give the opportunity for the audience to learn the tips and tricks of the aforementioned procedures.
