摘要
目的:探讨总PSA、游离PSA与前列腺穿刺、医学影像学诊断前列腺腺癌的价值。方法:采用统计学方法,回顾性分析152例前列腺腺癌患者诊断方面的临床资料。结果:152例患者游离PSA/总PSA(F/T)为0.17±0.11。若以0.20为界值,其阳性率可达77.6%;若以0.25为界值,其阳性率可达91.0%。对前列腺硬结患者行手法引导8针系统穿刺,其阳性率为77.6%;行B超引导下单纯结节穿刺,其阳性率为81.0%。74例前列腺腺癌患者中,69例经直肠前列腺超声(TRUS)检查阳性,71例MRI检查阳性。结论:F/T对“灰区”前列腺腺癌的鉴别诊断有积极意义;对前列腺硬结患者行单纯结节穿刺与系统穿刺,两者差别无统计学意义;TRUS和MRI检查对前列腺腺癌诊断价值的差别无统计学意义。
Objective： To investigate the value of TPSA, FPSA, biopsy and imaging in the diagnosis of prostate adenoeareinoma. Methods：The clinical data of the 152 cases were retrospectively analyzed. Results： The ratio of free-to-total PSA was 0.17±0.11, a cutoff 0.20 detected 77.6 % of cancers ; The positive biopsy rate was 77.6 for patients who had undergone eight-core multisite biopsy guided by DRE , which compares to 81.0% undergoing nodus biopsy guided by transreetal ultrasound technique. 69 positive cases detected by TRUS in 74 prostate adenocarcinoma patients, compared to 71 cases detected by MRI. Conclusions： F/T was useful to differentiate the prostate cancer in gray-field patients. System biopsy was not superior to the single nodus biopsy in patients with prostate callosity; The diaunostie value of TURS and MRI to prostate cancer had no significant differenee.
