目的探讨良性前列腺增生和前列腺钙化对前列腺特异性抗原(PSA)浓度的影响。方法将1681例患者分为单纯前列腺增生(A组,299例)、前列腺增生伴有钙化(B组,156例)、单纯前列腺钙化(C组,290例)、正常对照(D组,936例),对每组的PSA均值和异常检出率进行分析。结果年龄和PSA呈正相关;PSA均值和PSA异常检出率从高到低依次为:A组、B组、C组、D组。结论前列腺增生如发生钙化同时PSA较以往单纯增生时升高,应警惕前列腺癌的发生。
Objective To investigate the effect of benign prostatic hyperplasia and prostatic calcification on prostate-specific antigen (PSA) concentration. Methods A total of 1681 patients were divided into three groups: group A (299 cases), benign prostatic hyperplasia (group B: 156 cases), simple prostate calcification (group C: 290 cases), group D ), The PSA mean and abnormality of each group were analyzed. Results The age was positively correlated with PSA. The average detection rate of PSA and PSA abnormalities were A, B, C and D, respectively. Conclusion Prostatic hyperplasia, such as calcification and PSA than the previous hyperplasia increased, should be alert to the occurrence of prostate cancer.
