Lung cancer is the most common cancer diagnosed worldwide. Lung tumors can often be visualized with cone-beam CT but there are cases that can benefit from using fiducial markers, e.g. when there is atelectasis or when the tumor edges as blurry. Many doctors, however, hesitate to use fiducial markers in lung due to the risk of pneumothorax when using the relatively thick needles that are required to implant traditional fiducial markers.
Gold Anchor’s industry leading thin needles drastically reduce the risk of transthoracic implantation. And the marker can also be placed endoscopically.
Peripheral lung tumors
Transthoracic implantation of Gold Anchor in peripheral lung tumors is almost complication-free in comparison to implantation of traditional markers. Experience from needle aspiration biopsy indicates that 18G needles (frequently used for traditional markers) cause ten times as many pneumothoraces needing treatment as 22G/25G needles (used for Gold Anchor).
Central lung tumors
Some Gold Anchor users have chosen to transfer the Gold Anchor marker into 22G EBUS-TBNA needles. This enables placement of Gold Anchor through bronchoscope in central lung and esophageal tumors.
Transferring the Gold Anchor marker is easy since the Gold Anchor needle (GA150) can be inserted into the needle tip of the 22G EBUS-TBNA needle.
“In our radiation and interventional oncology practice at Austin Cancer Centers, we have found that by using the Gold Anchor system; this has allowed us to treat soft tissue tumors that were once considered inaccessible. Given the small gauge size of the needles, this has added a significant margin of safety that we had not previously enjoyed.”
