研究目的: |
本研究旨在针对血清PSA水平处于2–4 ng/ml区间的老年男性群体,构建一种基于尿液外泌体PSMA(PSMA-EVs)联合前列腺磁共振成像(MRI)的前列腺癌早期筛查策略。通过在北京市多中心社区前列腺癌筛查人群队列中开展研究,系统评估MRI在PSA 2-4ng/ml人群中的阳性率及进而前列腺穿刺阳性率,明确其在早期癌症检出中的作用;同时以穿刺活检病理结果为金标准,验证PSMA-EVs检测在诊断前列腺癌和非癌患者中的水平,分析其对高危人群的识别能力。进一步评估PSMA-EVs与MRI联合应用在提高临床显著性前列腺癌检出率方面的增益效应,并通过ROC曲线、诊断准确性指标等对比不同筛查路径的效能。 |

Objectives of Study: |
This study aims to establish an early screening strategy for prostate cancer based on urine-derived prostate-specific membrane antigen-expressing extracellular vesicles (PSMA-EVs) combined with prostate magnetic resonance imaging (MRI) for elderly men with serum PSA levels in the 2–4 ng/ml range. By conducting research within a multi-center community-based prostate cancer screening cohort in Beijing, the study will systematically evaluate the positive rate of MRI and the subsequent positive rate of prostate biopsies in individuals with PSA levels of 2–4 ng/ml, clarifying its role in early cancer detection. Additionally, using biopsy pathology results as the gold standard, the study will validate the levels of PSMA-EVs in patients diagnosed with prostate cancer versus non-cancer cases and analyze its ability to identify high-risk populations. Furthermore, the study will assess the added value of combining PSMA-EVs with MRI in improving the detection rate of clinically significant prostate cancer and compare the efficacy of different screening pathways using ROC curves, diagnostic accuracy metrics, and other indicators. |
