研究目的:

1、主要研究目的:明确PSA灰区患者中前列腺特异性抗原同源异构体2(p2PSA)截断值以辅助临床医师决策是否进行前列腺穿刺活检。 2、次要研究目的:I.明确PSA灰区患者中%p2PSA截断值以辅助临床医师决策是否进行前列腺穿刺活检。II.明确PSA灰区患者中前列腺健康指数(PHI)截断值以辅助临床医师决策是否进行前列腺穿刺活检。III.明确在PSA灰区患者中,根据PSA、%p2PSA、PHI诊断前列腺癌的灵敏度、假阴性率、特异度、假阳性率、阳性似然比、阴性似然比、变异系数、阴性预测值、阳性预测值及AUC面积。  

Objectives of Study:

1. Main research objective: To determine the truncation value of prostate-specific antigen homologous 2 (p2PSA) in PSA gray area patients to assist clinicians in deciding whether to perform prostate biopsy. 2. Secondary study objectives: I. To clarify the %p2PSA truncation value in PSA gray area patients to assist clinicians in deciding whether to perform prostate biopsy. II. Determine the cut-off value of prostate health index (PHI) in patients with PSA gray area to assist clinicians in deciding whether to perform prostate biopsy. III. Identify the sensitivity, false negative rate, specificity, false positive rate, positive likelihood ratio, negative likelihood ratio, coefficient of variation, negative predictive value, positive predictive value and AUC area of prostate cancer diagnosis in patients with PSA, %p2PSA and PHI.
