目的分析大连地区男性血清前列腺特异性抗原(PSA)水平,探讨建立本地区男性年龄相关PSA参考值范围,以提高PSA对本地区早期前列腺癌诊断的准确性。方法2011年1月至2016年6月,收集9 342例于大连医科大学附属第二医院健康体检男性的血液样本,排除存在下尿路症状者,最终共有8 453例成年男性纳入本研究。结果8 453例健康男性PSA中位数为 0.93 μ g/L,四分位数间距为 0.81 μ g/L,95%百分位数为 3.49 μ g/L。≤4.0 μ g/L 的8 169例(96.6%);<4.0~10.0 μ g/L的268例(3.2%);>10.0 μ g/L的16例(0.2%);各个年龄组PSA 95%百分位数分别为:20~<30岁0~1.67 μ g/L;30~<40岁 0~2.01 μ g/L;40~<50岁 0~2.41 μ g/L;50~<60岁 0~ 3.25 μ g/L;60~<70岁 0~3.92 μ g/L;70~<80岁0~5.48 μ g/L;≥80岁 0~9.35 μ g/L,各年龄组间均数差别有统计学意义(P < 0.01)。前列腺特异性抗原与年龄呈正相关 (r = 0.251,P < 0.001)。结论大连地区男性不同年龄段PSA水平存在明显差异,且均低于OESTERLING标准。筛查前列腺癌时,依据本地区年龄相关PSA参考值可能有益于前列腺癌的早期检出,降低过度诊疗的风险。

Abstract ObjectiveTo determine the age-specific normal ranges of serum prostate-specific antigen (PSA) levels in Dalian,China.MethodsSerum samples were collected from 8 453 asymptomatic men who underwent health examinations at the Second Affiliated Hospital of Dalian Medical University.ResultsThe median PSA level was 0.93 μ g/L,and the interquartile level was 0.81 μ g/L. The 95th percentile level was 3.49 μ g/L. The 95th percentile levels according to age group were:20 to <30 years,0 to 1.67 μ g/L; 30 to <40 years,0 to 2.01 μ g/L; 40 to <50 years,0 to 2.41 μ g/L; 50 to <60 years,0 to 3.25 μ g/L; 60 to <70 years,0 to 3.92 μ g/L; 70 to <80 years,0 to 5.48 μ g/L; and older than 80 years,0 to 9.35 μ g/L. The differences between the different age groups were statistically significant(P < 0.01). The serum PSA value was positively correlated with age (r = 0.251,P < 0.001).ConclusionThere were clear differences in age-specific PSA levels in Dalian,and these were lower than the standard OESTERLING. Screening for prostate cancer according to age-specific PSA reference values may be useful in the early detection of prostate cancer and may also reduce the risk of over-diagnosis.

前列腺癌是泌尿生殖系统最常见的恶性肿瘤之一[1],严重威胁广大男性患者的生命健康。血清前列腺特异性抗原(prostate-specific antigen,PSA)是目前国内外筛查前列腺癌的首选指标[2-3]。近几年越来越多的研究表明,PSA具有明显的种族特异性[4-6]及地域差异性[7-9]。我国筛查前列腺癌的PSA参考值一直沿用欧美国家标准,尚未建立符合我国国情及人种特征的标准。因此,本研究拟通过分析大连地区健康男性的PSA水平,建立适用本地区的年龄相关PSA参考值范围,提高本地区前列腺癌的早期检出率,降低过度诊疗的风险。……
