CT-Guided Fiducial Marker Implantation with Ultra-fine 25-Gauge Needle Prior to Proton Therapy for Liver Malignancies Abstract (extract), Purpose: Proton therapy is highly effective for liver malignancies, and to increase its accuracy, placement of fiducial markers in the liver is preferred. We retrospectively evaluated the safety and feasibility of CT-guided fiducial marker implantation using ultra-fine 25-gauge needles before proton therapy for liver malignancies. Materials […]

Conclusion: The Gold Anchors implantation is small invasive and safe method. The risk of side effects appearance is low. English, translation from Polish articlePolish original
Summary: This is the largest series reporting the feasibility and complications of the use of the Gold Anchor 25G system for percutaneous puncture in the lung. This is a quick procedure, performed under local anesthesia. A single marker per lesion minimizes the risk of complications related to the implementation: with a pneumothorax rate of 25% […]
Abstract: Visualization of markers is critical for imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). However, the size of the marker varies according to the imaging technique. While a large-sized marker is more useful for visualization in MRI, it results in artifacts on CT and causes substantial pain on administration. In […]
Summary: Gold Anchors were implanted through 22-gauge needle in two liver cancer patients at the Gifu Municipal Hospital in Japan. This caused little pain during placement under local anesthesia with xylocaine. No complication occurred in either patient. The iron-containing fiducial marker composed of 99.5% gold and 0.5% iron made visualization in MRI easy, which helped […]
Summary: Gold Anchors were implanted percutaneously under local anesthesia close to liver tumors in four patients at the Meiwa Hospital in Japan. All implantations were successfully performed with no complications. The markers were more visible than the uptake of lipiodol emulsion. The markers were also well detected in CB-CT images in all fractions. Article in […]
Summary: In Italy, ultrasound guided implantation in liver was performed in 50 patients of 68 gold grain markers 1×4 mm through 17-gauge needles, 78 Gold Anchors 0.4×10 mm through 22-gauge needles, and 17 Gold Anchors 0.28×10 mm through 25-gauge needles. The use of 17-gauge needles resulted in five patients developing abdominal pain and the migration […]
Abstract: In 621 consecutive prostate cancer patients, the frequency of urinary tract infections (UTI) and marker loss was evaluated. They prophylactically received a single dose of non-broad-spectrum antibiotics and transrectal implantation of three thin needle fiducial markers, Gold Anchor ™ (GA). The occurrence of UTIs, sepsis, hospitalization due to infection, and marker loss after implantation […]
Summary: Gold Anchors were implanted percutaneously via the trans-thoracic route in lung in 80 patients for CyberKnife treatments at the Hartmann Radiotherapy Institute in France. This led to 9 cases (11%) of pneumothorax, out of which 2 cases (2.5%) required a drain. All implanted fiducials were effectively tracked by CyberKnife. Article in Radiation Oncology, 2019
