研究设计:

Study design:

Cross-sectional 

研究目的:

本研究旨在构建基于PCA3表达水平与PSA检测值(包含PSA、tPSA、f/t PSA)、PSAD、mpMRI(PI-RADS评分)等常用临床指标的无创诊断模型,在前列腺癌穿刺活检前对PSA水平4-20ng/ml人群进行辅助诊断与风险分层,提高前列腺癌的检出率和诊断准确性,优化穿刺决策,减少不必要的穿刺操作。  

Objectives of Study:

The aim of this study is to develop a noninvasive diagnostic model based on PCA3 expression levels combined with commonly used clinical parameters, including PSA measurements (PSA, tPSA, f/t PSA), PSA density (PSAD), and multiparametric MRI (PI-RADS score), to assist in diagnosis and risk stratification of patients with PSA levels of 4–20 ng/mL prior to prostate biopsy, thereby improving prostate cancer detection and diagnostic accuracy, optimizing biopsy decision-making, and reducing unnecessary biopsy procedures.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

拟进行前列腺穿刺的45岁以上且PSA为4-20ng/mL的男性

Inclusion criteria

Male patients aged 45 years or older who are scheduled to undergo prostate biopsy and have a PSA level between 4 and 20 ng/mL.

排除标准:

1.未完成前列腺穿刺检查,无法确诊: 2.1年内接受过抗雄激素药物治疗的受试者; 3.有既往前列腺癌病史或前列腺癌手术史的受试者 4.研究者认为不适宜参加本临床试验者。

Exclusion criteria:

1. Failure to complete prostate biopsy, resulting in the inability to obtain a definitive diagnosis; 2. Receipt of anti-androgen therapy within the past 12 months; 3. History of prostate cancer or prior prostate cancer–related surgery; 4. Any condition that, in the investigator’s judgment, makes the subject unsuitable for participation in the study.

45岁以上,PSA为4-20ng/mL的拟进行前列腺穿刺的男性,且需满足1年内未接受过抗雄激素药物治疗,无既往前列腺癌病史或前列腺癌手术史的要求。

例数:

Sample size:

60

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Male patients aged 45 years or older with PSA levels of 4–20 ng/mL who are scheduled to undergo prostate biopsy, and who have not received anti-androgen therapy within the past year, with no history of prostate cancer or prior prostate cancer–related surgery.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

PSA 水平 4–20 ng/mL 灰区内,与前列腺癌在临床表现和实验室指标上不易区分的疾病人群,包括良性前列腺增生、前列腺炎等。研究设计中应避免采用正常人群作为对照。

例数:

Sample size:

120

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Populations with diseases that are easily confounded with prostate cancer:Populations with diseases that are difficult to differentiate from prostate cancer in patients with PSA levels of 4–20 ng/mL, including benign prostatic hyperplasia and prostatitis. Case–control designs using healthy individuals as controls should be avoided.
