What is the purpose of this trial?

This trial tests a new device called the STING-MARK Universal Fiducial Marker System, which helps doctors precisely locate tumors during image-guided treatments. The device aims to be easy to use and reliable, improving on current methods that are often inaccurate. Participants in this study will help demonstrate the device's effectiveness in identifying tumors. The trial seeks individuals undergoing surgery to remove solid organs or who have received a solid organ transplant. As an unphased trial, it offers participants the chance to contribute to advancements in medical technology that could enhance surgical precision.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the STING-MARK device is safe for use in image-guided therapies?

Research shows that the STING MARK Universal Fiducial Marker System can be safely placed in the body using regular biopsy needles. Previous studies found that this system is easy to use and compatible with various needle types. The device aids doctors in marking and locating tumors more accurately with x-rays.

Although specific data on side effects is not available, its testing in clinical trials suggests an expectation of safety. This trial primarily focuses on the device's effectiveness rather than its side effects. While no safety issues have been reported, participants should discuss any concerns with the medical team involved in the trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the STING MARK Universal Fiducial Marker System because it offers a new way to precisely locate and target cancerous tumors during treatment. Unlike standard fiducial markers, which may not be as versatile or accurate across different organs, STING MARK is designed for universal use with organ-specific routes and imaging guidance, potentially improving precision. This system could enhance the accuracy of treatments like radiation therapy by ensuring that the therapy is delivered exactly where it's needed, minimizing damage to surrounding healthy tissues.

What evidence suggests that the STING-MARK device is effective for accurately pinpointing tumor locations?

Research has shown that fiducial markers, such as those in the STING MARK system, help doctors aim radiation treatments more precisely at tumors. In this trial, participants will receive the STING MARK, a new type of marker that is easy to see on X-rays and can be placed directly into the tumor using a needle. This system also allows doctors to take a small tissue sample, called a biopsy, before placing the marker. Early results suggest that this could enhance the accuracy and effectiveness of image-guided cancer treatments. ^{1 2 3 5 6}

Fiducial markers used for prostate positioning can migrate by more than 2 mm, which may affect the accuracy of patient positioning during treatment, especially in techniques like stereotactic body radiation therapy (SBRT).

The study developed an optimal registration algorithm that showed minimal patient setup error, averaging around 1.10 mm, but highlighted that small registration errors do not necessarily indicate good patient positioning due to potential marker migration.

Fiducial marker placement for primary liver tumors in patients with hepatocellular carcinoma is generally safe, with a high quality of placement achieved in 93% of cases by experienced practitioners, compared to only 30% in earlier cohorts.

Complications and longer recovery times are more likely in patients with poor performance status and during the learning curve of the procedure, highlighting the importance of experience in minimizing risks.

In a study of 29 patients undergoing image-guided radiation therapy, GoldAnchorTM fiducial markers implanted in the prostate showed minimal migration, averaging 0.17 cm, which is likely not clinically significant for treatment accuracy.

The research suggests that while some marker movement occurs during treatment planning, timely initiation of radiation therapy and continuous monitoring of marker position can help maintain treatment precision.

In a study of nine patients with recurrent prostate cancer, the presence and type of fiducial markers significantly affected the effectiveness of MR-guided transurethral ultrasound ablation (TULSA), with 70% of markers allowing for successful thermal dose accumulation to the target area.

Gold markers caused less disruption to treatment compared to nitinol markers, which created large artifacts that interfered with temperature measurements, highlighting the importance of careful selection and placement of markers to optimize treatment outcomes.

The study demonstrated that cystoscopy-guided placement of hydrogel markers in 32 patients with muscle-invasive bladder cancer is safe, with no procedure-related adverse events reported.

While 76.6% of the markers were sufficient for tumor delineation at the start, only 46.7% remained visible and adequate for routine verification by the end of treatment, indicating a need for improvement in marker performance during radiation therapy.
