摘要:目的 探讨尿液中肌氨酸、PCA3mRNA,血清PSA在前列腺癌早期临床诊断中的应用。方法 收集2016年9月~2017年12月在我院收治的前列腺增生患者62例以及前列腺癌患者62例(病理确诊)作为研究对象,前列腺癌患者为研究组,前列腺增生患者为对照组。以两组患者进行前列腺按摩后的初始尿液为标本,采用实时荧光定量对肌氨酸、PCA3mRNA,血清PSA进行检测,比较两组患者肌氨酸、PCA3mRNA,血清PSA的差异并统计两组患者的诊断准确度。结果 研究组患者诊断准确度高于对照组,差异具有统计学意义(P<0.05);研究组患者尿肌氨酸、PCA3mRNA,血清PSA水平分别为(13.51±2.54)ng/ml、(6.09±0.56)ng/ml、(0.53±0.07)μmol/L,高于对照组的(7.60±0.27)ng/ml、(2.03±0.21)ng/ml、(0.36±0.04)μmol/L,差异具有统计学意义(P<0.05)。结论 早期联合监测尿液中的肌氨酸、PCA3mRNA及血清PSA水平,可以提高前列腺癌的监测有效率,为患者提供更为便利的诊断手段。

Abstract:Objective To investigate the application of sarcosine, PCA3mRNA and serum PSA in the early diagnosis of prostate cancer. Methods A total of 62 patients with benign prostatic hyperplasia and 62 patients with prostate cancer (pathological diagnosis) were enrolled in our hospital from September 2016 to December 2017. The patients with prostate cancer were the study group and the patients with benign prostatic hyperplasia were the control group. The initial urine of the two groups of patients after prostate massage was used as the specimen. Real-time fluorescence quantification was used to detect sarcosine, PCA3mRNA and serum PSA. The differences of serum PSA between serum and PCA3mRNA were compared and the diagnostic accuracy of the two groups were statistically analyzed.Results The diagnostic accuracy of the study group was higher than that of the control group,the difference was statistically significant (P<0.05). The urinary creatinine, PCA3mRNA and serum PSA levels in the study group were (13.51±2.54) ng/ml, (6.09± 0.56) ng/ml, (0.53±0.07) μmol/L, higher than the control group (7.60±0.27) ng/ml, (2.03±0.21) ng/ml, (0.36±0.04) μmol/L,the difference was statistically significant (P<0.05).Conclusion Early monitoring of urinary creatinine, PCA3mRNA and serum PSA levels in urine can improve the efficiency of prostate cancer monitoring and provide a more convenient diagnostic tool for patients.

目前腫瘤性疾病已成为社会日益关注的问题,因肿瘤带来的社会问题日益突出,我国每年大概有2500万肿瘤患者,美国前列腺癌的患者每年超过了100万人。统计显示前列腺癌患者的年龄化正逐渐降低,患者的人数不断增加,据预测,10年后我国前列腺癌发病率在男性恶性肿瘤中的排行将晋升至前3位。目前临床上最常用的前列腺癌肿瘤标志物是血清前列腺特异抗原(PSA),尽管血清PSA检测可以发现早期前列腺癌,但该方法特异度不高,特别是PSA水平处于4~10 ng/ml这个检测灰区的患者,活检阳性率仅有20.4%[1]。有报道通过肌氨酸、PCA3mRNA,血清PSA等特异性检测方法对前列腺癌进行诊断,结果显示其具有无创、精确度高等多种优势,成为了一种新起的检测方法[2]。为此,本研究旨在观察尿液中肌氨酸、PCA3mRNA、血清PSA水平在前列腺癌早期临床诊断中的应用价值,现报道如下。……
