PSMA PET/CT通过靶向肿瘤新生血管的PSMA表达，在肾透明细胞癌（ccRCC）诊断中展现高灵敏度（80-90%），并作为VHL-HIF-VEGF轴的生物标志物，指导抗血管生成治疗（如TKI）和免疫疗法（IO）的联合应用选择。其定量参数（SUVmax、异质性指数）可预测治疗反应，PSMA引导的 ...

本综述深入探讨了PSMA-PET（前列腺特异性膜抗原-正电子发射断层扫描）在局限性前列腺癌（PCa）患者接受高强度聚焦超声（HIFU）局部治疗后的监测价值。文章指出，标准监测方案（基于PSA和mpMRI）在识别治疗后区域复发方面存在局限，而PSMA-PET凭借其高特异性 ...

Prostate cancer is the most common cancer in men and the second-leading cause of cancer-related deaths in men in the US. There’s a new and promising diagnostic procedure for prostate cancer known as ...

Researchers in Denmark conducted a prospective single-centre study including 160 patients with newly diagnosed high-risk prostate cancer between 2021 and 2024. All the participants first underwent an ...

A team of researchers in Australia and New Zealand has found that MRI scans can detect prostate cancer more accurately than the newer, prostate-specific -PSMA PET/CT scanning technique. The findings ...

Figure 1. A 74-y-old man at initial staging with PSMA PET that demonstrates low uptake in primary tumor (A, arrowhead) and left pelvic side wall node (A, arrow). Bone scan was read as positive by 2 of ...

For men with newly diagnosed prostate cancer, PSMA PET has a moderate sensitivity but very high specificity for identifying lymph nodes in the pelvis that harbor prostate cancer; this means that an ...

Fluorine-18 prostate-specific membrane antigen (PSMA)-1007 PET/CT was superior to multiparametric MRI for primary locoregional staging of prostate cancer, according to results from a phase II ...
