A novel molecular imaging agent targeting glypican-3 (GPC3) has demonstrated high sensitivity and specificity in detecting hepatocellular carcinoma (HCC), including tumors smaller than one centimeter, according to results from a pilot clinical study. The agent, 68Ga-aGPC3-scFv, coded as XH06, was shown to be safe, well-tolerated, and effective at providing high-contrast images of GPC3-positive liver tumors, offering a promising new tool for early diagnosis and staging of HCC—one of the most lethal forms of liver cancer. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting.
