摘要
目的探讨前列腺体积及前列腺穿刺针数对前列腺癌诊断情况的影响并分析其原因。方法回顾性总结2002∽2009年间于我院行超声引导下经直肠前列腺系统12针穿刺292例患者的临床资料。患者PSA在o~20ng/mL之间。经直肠超声计算前列腺体积。将患者按照前列腺体积分为:〈30mL,30∽60mL,60∽90mL,〉90mL四组,比较各组前列腺穿刺6针、8针、10针、12针时前列腺癌诊断率。统计学Fisher’S检验比较各组间差异性。结果总体前列腺癌诊断率为25%(73/292),在〈30mL组:6针、8针、10针、12针的前列腺癌诊断率相同,均为39.13%(21/54);在30~60mL组:6针、8针、10针、12针的诊断率分别为:21.3%(23/108)、23.1%(25/108)、23.1%(25/108)、24.1%(26/108),诊断率无显著差异(P〉0.05)。在60~90mL组:6针的诊断率为12.9%(12/93),显著低于8针(19.4%(18/93)3、10针[20.4%(19/93)]、12针(20.4%(19/93)]的诊断率(Pd0.05)。在〉90mL组:6针、8针的诊断率均为8.1%(3/37),显著低于10针、12针的诊断率C18.9%(7/37),P〈0.053。黠论前列腺体积是选择前列腺穿刺针数时的一个重要的参考因素,在前列腺体积较大的情况下,可适当的增加前列腺穿刺针数,在前列腺体积较小的情况下,增加前列腺穿刺针数并不能提高前列腺癌的诊断率。
Objective To investigate the relationship between prostate volume, prostate biopsy cores and Pca detection rate. Melhods A total of 292 patients with PSA between 0 and 20 ng/mL and/or abnormal DRE underwent 12 ∽ core prostate biopsy from Jan. 2002 to Dec. 2009. Prostate volume was detected with transrectal ultrasound. All patients were divided into ∽30 mL, 30∽60 mL, 60∽90 mL, and 990 mL groups according to prostate volume. And then the Pca detection rates of 6∽, 8∽, 10∽ and 12∽ core protocols in each group were compared. Rest/Its The total Pca detection rate was 25.0% (73/292). In ∽ 30 mL group, Pca detection rates were the same for each protocol (39.13%, 21/54). In 30∽60 mL group, Pea detection rates of 6∽ core (21.3%, 23/108), 8∽ core (23.1%, 25/108), 10∽ core (23.1%, 25/108) and 12∽ core (24. 1%, 26/108) were not significantly different (P〉0. 05). In 60∽ 90 mL group, 6∽core (12.9%, 12/93) protocol had significantly lower Pca detection rate (P〈0.05) than. 8∽core (19.4%, 18/93), 10~ core (20.4%, 19/93), 12∽ core (20.4%, 19/93) protocols. In ∽90 mL groups, Pea detection rates of 6∽ core (8. 1%, 3/37), 8∽ core (8.1%, 3/37) protocols were significantly lower (P〈0.05) than 10∽ core (18. 9%, 7/37), 12∽ core (18.9%, 7/37) protocols. Conclt/sions Prostate volume can be an important index for the choice of core. Increased cores will not improve Pca detection rate if the vrostate volume is not be considered.
