Breast cancer is the most common cancer diagnosed in women worldwide. It is common to mark the surgical cavity after lumpectomy with surgical clips that can be visualized on CBCT. Those clips may, however, not provide sufficient visibility for automated marker tracking systems. And it is sometimes also difficult to attach these markers to the tumor bed.
Radiotherapy boost treatment are becoming more and more common as well as the delineation of the target area on MRI. Gold Anchor markers provide strong tissue attachment in the tumor bed and provide good visibility both on kV and MR images.
Gold Anchors can be implanted during surgery to mark the surgical cavity after lumpectomy. The markers can then be used to improve accuracy in delineation of the surgical cavity and for the verification of breast position during IGRT.
Image guidance may improve whole breast irradiation outcomes by ensuring adequate coverage of the target tissue on a daily basis while allowing smaller margins around the targets, thereby reducing exposure to lung and heart (for left sided cases).
Marker based IGRT is also useful for APBI (Accelerated Partial Breast Irradiation).
Gold Anchor can also be placed percutaneously in breast, e.g. to facilitate a boost to breast tumors prior to surgery.
