研究目的: |
本研究旨在针对PSA水平小于4 ng/ml人群PCa检出率低、易漏诊的问题,开发并验证一种融合尿液PCA3表达水平、血浆cfDNA基因组特征、mpMRI影像学特征、血清PSA水平及患者临床特征的多模态 AI 模型,在PSA水平小于4 ng/ml人群中检测PCa,并区分csPCa,进行风险分层,以提高PCa的检出率和诊断准确性,减少漏诊率,优化穿刺决策。 |

|
Objectives of Study: |
This study aims to address the problems of low detection rate and high missed diagnosis rate of prostate cancer (PCa) in populations with a serum PSA level of less than 4 ng/mL. We intend to develop and validate a multimodal artificial intelligence (AI) model that integrates urinary PCA3 expression levels, plasma cell-free DNA (cfDNA) genomic features, multiparametric magnetic resonance imaging (mpMRI) radiological features, serum PSA levels and patients' clinical characteristics. The model is designed for PCa detection, differentiation of clinically significant prostate cancer (csPCa) and risk stratification in populations with a serum PSA level of less than 4 ng/mL, so as to improve the detection rate and diagnostic accuracy of PCa, reduce the missed diagnosis rate and optimize biopsy decision-making. |

纳入标准: |
1.发现队列入选标准为计划进行前列腺活检的患者,包括: (1)直肠指诊(DRE)发现前列腺可疑结节;(2)经直肠前列腺超声(TRUS)或MRI发现可疑病灶; (3)血清 PSA>10 ng/ml; (4) 血清PSA 4-10ng/ml,fPSA(游离前列腺特异性抗原)/tPSA < 0.16 或 PSAD(前列腺特异性抗原密度) > 0.15 (ng/mL/cm^3) 或 PSAV(前列腺特异性抗原速度) > 0.75 (ng/mL/year) 。 2.内部验证队列和外部验证队列入选标准为血清PSA<4 ng/mL,且因DRE、TRUS或MRI发现可疑病灶或其他原因,拟进行前列腺穿刺的男性。 |

|
Inclusion criteria |
1. The selection criteria for the discovery team include patients scheduled for prostate biopsy, as follows: (1) Suspicious nodules in the prostate detected by digital rectal examination (DRE); (2) Suspicious lesions identified by transrectal prostate ultrasound (TRUS) or MRI; (3) Serum PSA > 10 ng/ml; (4) Serum PSA 4-10 ng/ml, with fPSA/tPSA < 0.16 or PSAD > 0.15 (ng/mL/cm^3) or PSAV > 0.75 (ng/mL/year). 2. The selection criteria for the internal validation cohort and the external validation cohort are men with serum PSA < 4 ng/mL who are scheduled for prostate biopsy due to suspected lesions detected by DRE, TRUS, or MRI or for other reasons. |
||||||||||||||||||||||
|
排除标准: |
1.未完成mpMRI检查或mpMRI扫描不完整或质量欠佳; 2.cfDNA质量或数量不足以进行测序; 3.关键临床或病理数据缺失; 4.未完成前列腺穿刺检查,无法确诊的受试者; 5.有既往PCa病史或接受过PCa治疗史(包括手术、放疗或雄激素剥夺疗法); 6.有既往前列腺增生且口服5α-还原酶抑制剂(如非那雄胺)的患者,或曾接受过前列腺增生手术(包括TURP、热蒸汽、前列腺悬吊等)的患者; 7.研究者认为不适宜参加本临床试验者。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. The mpMRI examination was not completed or the mpMRI scan was incomplete or of poor quality; 2. The quality or quantity of cfDNA is insufficient for sequencing; 3. Key clinical or pathological data are missing; 4. The prostate biopsy was not completed and the subject could not be diagnosed; 5. Has a previous history of PCa or has received PCa treatment (including surgery, radiotherapy or androgen deprivation therapy); 6. Has a previous history of benign prostatic hyperplasia and is taking 5α-reductase inhibitors (such as finasteride), or has undergone prostate hyperplasia surgery (including TURP, thermal vaporization, prostate suspension, etc.); 7. Subjects considered not suitable to participate in this clinical trial by the investigators. |
