Transrectal ultrasonographic features of prostate in BPH were studied in 563 patients with the volume of the whole prostate and the transitional zone measured and in 45 the actual weight of the surgical specimens at suprapubic prostatectomy has been assessed for comparative studies. The preoperative ultrasonographic assessment of the transitional zone volume correlated very well with the weight of the resected prostate (r=0.988, P<0.001, error=4.0%). So, transrectal ultrasonography with high resolution multiplannar probes (7.5MHz)could reliably assess the size of the whole prostate and that of the adenomas providing accurate preoperative evaluation.

为探讨良性前列腺增生症(BPH)腔内B超特征及超声所测定量指标与手术切除标本重量间的相互关系,对563例BPH患者进行了经直肠B超检查,测定整个腺体及移行带体积并与45例手术标本行相关回归分析。结果发现:BPH有其特有声像特征,移行带体积与手术标本重量值呈显著相关性(r=0988,P<0001,误差为4%);腺体体积与手术标本重量值间也成直线相关性,但误差达478%。使用多平面高频75MHz探头的经直肠B超可以准确估计前列腺及增生腺体的大小,前列腺区带的定量学研究对减少超声误差,指导BPH诊断及治疗十分重要。

Objective To evaluate the prostate specific antigen density of the transition zone in detecting prostate cancer. Methods Serum PSA was determined by the Abbott IMX assay,the volumes of entire prostate and the transition zone were determined by transrectal ultrasound, the total prostate PSA density (PSAD) and prostate specific antigen density of the transition zone (PSAT) were calculated.Of the 118 patients,30 had prostate cancer and 88 BPH. Results With PSA in the range of 4~10 ng/ml,the total prostate PSA density in subjects with PCa was 0.26±0.11 where as it was 0.13±0.06 in patients with PBH,PSAT was 1.04±0.70 in PCa and 0.21±0.1 in BPH ( P <0.01).If a total prostate PSA density of 0.15 had been chosen as the cutoff value cancer detection might be missed in 27% of the patients compared to only 9% if the cutoff value was set to 0.35 for PSA density of the transition zone ( P <0.01). Conclusions The prostate specific antigen density of the transition zone is a new effective parameter in detecting prostate cancer.With a PSA range of 4~10 ng/ml,PSAT is much more accurate in detecting prostate cancer than PSAD.

目的 评价前列腺移行带特异抗原密度 (PSAT)检测前列腺癌 (PCa)的临床价值。 方法 用酶免法测定 30例PCa及 88例良性前列腺增生症 (BPH)患者血清PSA水平 ,用经直肠前列腺B超测定患者总前列腺体积及移行带体积 ,并计算PSA密度 (PSAD)及PSAT值。 结果 PSA在 4~ 10ng/ml时 ,PCa和BPH患者PSAD值分别为 0 .2 6± 0 .11、0 .13± 0 .0 6 ,两组间相比差别具有显著性意义 (P <0 .0 1) ;PSAT值则分别为 1.0 4± 0 .70、0 .2 1± 0 .13 ,两组间相比差别具有显著性意义 (P <0 .0 1)。若选择PSAD =0 .15作为判断患者是否需穿刺活检的标准 ,将有 2 7%的PCa漏诊 ,而若选择PSAT =0 .35作为判断患者是否需穿刺活检的标准 ,只有 9%的PCa漏诊 (P <0 .0 1)。 结论 PSAT是一种新的有效的检测PCa的方法 ,PSA在 4~ 10ng/ml范围时 ,用PSAT检测PCa较用PSAD更精确。

Methods The retrospective study included 153 patients being suspected for early PCa with serum PSA<20 ng·ml -1. Biopsy of the prostate was performed for all these patients. Results Of 153 patients, 100 were histologically confirmed as benign prostatic hyperplasia(BPH) and 53 as PCa. There was significant difference in mean PSAD and PSA-TZ between...

Objective To define the role of serum PSA density (PSAD) and PSA density of the transition zone (PSA-TZ) for the early detection of prostatic cancer(PCa). Methods The retrospective study included 153 patients being suspected for early PCa with serum PSA<20 ng·ml -1. Biopsy of the prostate was performed for all these patients. Results Of 153 patients, 100 were histologically confirmed as benign prostatic hyperplasia(BPH) and 53 as PCa. There was significant difference in mean PSAD and PSA-TZ between the PSA positive and PSA negative patients. PSAD was (0.13±0.11)ng·ml -1·ml -1 for the negative and (0.30±0.21)ng·ml -1·ml -1 for the positive. PSA-TZ was (0.26±0.20)ng·ml -1·ml -1 for the negative and (0.78±0.71)ng·ml -1·ml -1 for the positive. The difference was more obvious in smaller prostate (the prostate volume <50 ml or the transition zone <25 ml). In ROC curves, area under the curve of PSAD(0.73) and PSA-TZ(0.74) had no difference but both of them were much larger than that of PSA(0.57). Conclusions PSAD and PSA-TZ are more accurate in screening the prostatic cancer than PSA in patients with PSA<20 ng·ml -1 and the cut-off value should be adjusted according to the volume of prostate or its transion zone.
