目的探讨前列腺癌(prostate cancer,PCa)患者血清总前列腺特异性抗原(total prostatespecific antigen,tPSA)、游离前列腺特异性抗原(free prostate-specific antigen,fP SA)及其比值(percentage of fPSA to tPSA,f/tPSA)、结合前列腺特异性抗原(complexed prostate-specific antigen,c PSA)及其比值(percentage of c PSA to tPSA,c/tPSA)对Gleason评分的预测价值。方法回顾性分析我院2011年12月1日至2014年12月1日依病理报告确诊为PCa,且术前血清前列腺特异性抗原(prostate-specific antigen,PSA)检查满足tPSA<100 ng/mL的病例。将所纳入病例按照tPSA<10 ng/mL、10 ng/mL≤tPSA<20 ng/mL及20 ng/mL≤tPSA<100 ng/mL的标准分为3组。明确不同血清tPSA区间内,上述各项预测指标与Gleason评分的相关性。结果纳入214例PCa患者中...
【英文摘要】
Objective To determine the predictive value of total prostate-specific antigen( tPSA),free prostate-specific antigen( fP SA),ratio of fP SA to tPSA( f / tPSA),complexed prostate-specific antigen( c PSA) and percentage of c PSA to tPSA( c /tPSA) for the Gleason score in prostate cancer( PCa). Methods A retrospective study was performed on 241 patients of pathologically verified PCa whose tPSA less than100 ng / mL in our hospital from December 1,2011 to December 1,2014. The cohort was divided into 3groups acc...
