Cervical cancer is the seventh most common cancer diagnosed worldwide. The cervix is prone to movement. Changes in target position and shape may be caused by rectum- and bladder-filling changes, but may also be due to tumor shrinkage during radiotherapy. Fiducial markers are therefore useful to guide both external-beam and internal radiotherapy (brachy). However, traditional markers have a tendency to migrate and fall out of the vaginal wall and cervix while Gold Anchors expand outside the needle and anchor in the tissue.
Gold Anchor may offer the following benefits for GYN treatments;
- Strong tissue attachment not only in cervix but also in the vaginal wall enabling marking of lower border for tumors growth outside of cervix.
- Enhanced MRI visibility due to the unique material can help the fusion of CT & MRI images.
- For brachy treatments Gold Anchor can be used as a point of reference to verify the position of the applicator before the treatment starts.
“We are using Gold Anchors to achieve a more reliable localization over time for our gynecology patients.”
Gold Anchor MR+ for gyn
Until recently, all Gold Anchor markers were made of an alloy of 99.5% pure gold and 0.5% pure iron. Since December 2020, Gold Anchor markers are also made of an alloy of 98.5% pure gold and 1.5% pure iron. Products that include the new markers are called Gold Anchor MR+. These products are currently available in Europe and the USA.
