Innovative Dual-Imaging Tracer Poised to Revolutionize Prostate Cancer surgery
Vancouver, British Columbia – Researchers at the University of British Columbia (UBC) have unveiled a groundbreaking “dual-fashion” tracer that promises to significantly improve the precision and safety of prostate cancer surgery. This novel technology combines the strengths of positron emission tomography (PET) imaging with fluorescence visualization, offering surgeons an unprecedented ability to identify and remove cancerous tissue while minimizing damage to surrounding healthy areas.
The newly developed tracer utilizes a single molecule labeled with Fluor-18, a commonly used PET isotope, alongside fluorescein, a well-established fluorescent dye in medicine. This dual approach allows surgeons to leverage preoperative PET scans for planning and intraoperative guidance using both a Geiger counter and direct visual cues, streamlining the surgical process.
Enhanced Precision Through combined Imaging
“Our tracer enables the visualization of tumors and metastases with high resolution and real-time detection, even when they are not immediately apparent,” explained Dr. David M. Perrin, the lead chemist at UBC.This capability is especially crucial in identifying microscopic disease spread, a common challenge in prostate cancer treatment.
The tracer specifically targets prostate-specific membrane antigen (PSMA), a protein highly expressed on the surface of prostate cancer cells. this targeted approach ensures the tracer concentrates in malignant tissue, including lymph nodes and distant metastases.
Did You Know?
PSMA is a key biomarker for prostate cancer, making it an ideal target for imaging and therapy.
Radiochemist Jerome Lozada, who conducted the experiments, emphasized the accessibility of the technique, noting its potential for use in smaller healthcare facilities due to its lack of reliance on specialized equipment.
Promising Results in preclinical Trials
The research team successfully tested the tracer in mice implanted with human prostate cancer tumors, demonstrating its effectiveness in identifying and delineating cancerous tissue.The next steps involve Good Manufacturing Practice (GMP) production,extensive toxicity studies,and preparation for human clinical trials. Researchers anticipate the tracer will not only improve the accuracy of lymph node removal but also reduce the incidence of positive surgical margins - a frequent complication in radical prostatectomies.
External experts,such as Professor Larry Goldenberg of the Vancouver Prostate Center,have lauded the development as a powerful tool for optimizing the balance between effective cancer control and the preservation of vital structures like nerves and the bladder. They also foresee potential applications in other cancers, including ovarian and laryngeal cancers.
This dual-imaging tracer represents a significant step toward more personalized and minimally invasive cancer treatment, prioritizing precision at every stage. The study’s findings were recently published in the Journal of Medical Chemistry.
Advancements in Prostate Cancer Treatment: A Broader Perspective
Innovation in prostate cancer treatment extends beyond this new tracer.In 2020, researchers at the University Medical Center Groningen (UMCG) developed a novel fluorescent tracer, ONM-100, that activates based on the pH levels within tumors, offering a “one-size-fits-all” solution for image-guided oncological surgery .
Furthermore, the Isala hospital has recently implemented an Elekta EVO CT-Linear accelerator, incorporating artificial intelligence (AI) to deliver highly precise radiation therapy. This technology allows clinicians to more accurately distinguish between tumor and healthy tissue, leading to more effective and patient-centered treatments .
Pro Tip:
Early detection and advanced imaging are crucial components of effective prostate cancer management.

Prostate cancer: A Growing Global Health concern
Prostate cancer remains one of the most commonly diagnosed cancers in men worldwide. According to the American Cancer Society, about 1 in 8 men will be diagnosed with prostate cancer during their lifetime. Early detection through screenings like prostate-specific antigen (PSA) testing and digital rectal exams is vital for improving treatment outcomes. Ongoing research continues to focus on developing more targeted therapies and improving the accuracy of diagnostic tools, such as multiparametric MRI and PSMA PET scans. The development of less invasive surgical techniques, like robotic-assisted prostatectomy, also contributes to better patient recovery and quality of life.
