探讨超声造影在不同前列腺特异抗原(PSA)水平前列腺癌穿刺活检中的价值。
对2017年10月至2021年7月于嘉善县第一人民医院就诊的593例血清PSA升高(≥4 ng/ml)的患者行经会阴前列腺穿刺活检,根据穿刺前是否行超声造影分为常规组(A组,319例)与造影组(B组,274例),再根据血清PSA浓度将患者分为6组,4~10 ng/ml为常规A1组(141例)和造影B1组(108例),>10~20 ng/ml为常规A2组(108例)和造影B2组(92例),>20 ng/ml为常规A3组(70例)和造影B3组(74例)。造影组采用超声造影靶向穿刺联合系统穿刺,常规组采用10点法系统穿刺。采用t检验比较常规组与造影组患者的年龄、PSA浓度、前列腺体积、PSA密度的差异;以病理结果为对照,计算不同穿刺方法前列腺癌的检出率,采用χ2检验比较不同PSA浓度下常规组与造影组前列腺癌检出率的差异。
常规组与造影组年龄[(72.38±6.11)岁 vs(73.26±6.64)岁]、PSA浓度[(15.98±8.52)ng/ml vs(18.43±9.89)ng/ml]、前列腺体积[(35.81±17.88)ml vs(34.37±16.56)ml]、PSA密度[(0.44±0.37)ng/ml2 vs(0.50±0.43)ng/ml2]方面比较,差异均无统计学意义(P均>0.05)。593例患者中共检出前列腺癌287例(287/593,48.4%),常规组检出率为44.8%(143/319),造影组检出率为52.6%(144/274),2种穿刺法前列腺癌的总检出率比较,差异无统计学意义(P>0.05)。在PSA 4~10 ng/ml患者中常规A1组前列腺癌检出率为31.9%(45/141),低于造影B1组检出率(44.4%,48/108),2组差异具有统计学意义(χ2=4.10,P=0.043);PSA>10~20 ng/ml患者中常规A2组检出率为42.6%(46/108),造影B2组检出率为47.8%(44/92);PSA>20 ng/ml患者中常规A3组检出率为74.3%(52/70),造影B3组检出率为70.3%(52/74),2组检出率差异均无统计学意义(P均>0.05)。
对于PSA 4~10 ng/ml水平的患者,超声造影靶向穿刺联合系统穿刺可提高前列腺癌的检出率。

To evaluate the value of contrast-enhanced ultrasound (CEUS) in prostate cancer biopsy in patients with different prostate specific antigen (PSA) levels.
From October 2017 to July 2021, 593 patients who had elevated serum PSA (≥4 ng/ml) and underwent transperineal prostate biopsy at the First People's Hospital of Jiashan County, Zhejiang Province were enrolled. They were divided into either a conventional ultrasound group (group A, 319 cases) or a CEUS group (group B, 274 cases) based on whether CEUS was performed before biopsy or not. Moreover, the two groups of patients were further divided into 6 subgroups based on serum PSA concentration: subgroup A1 (141 cases) and subgroup B1 (108 cases) with a serum PSA concentration of 4-10 ng/ml; subgroup A2 (108 cases) and subgroup B2 (92 cases) with a serum PSA concentration more than 10-20 ng/ml; subgroup A3 (70 cases) and subgroup B3 (74 cases) with a serum PSA concentration more than 20 ng/ml. The patients in the CEUS group underwent targeted biopsy (TB) combined with systematic biopsy (SB), while the patients in the conventional ultrasound group underwent 10-point SB. The t-test was performed to compare the age, the value of PSA concentration, prostate volume, and PSA density of patients between the two group. The χ2 test was performed to compare the detection rate of prostate cancer between different subgroups.
There was no significantly difference between the conventional ultrasound group and the CEUS group in age [(72.38±6.11) years vs (73.26±6.64) years], PSA concentration [(15.98±8.52) ng/ml vs (18.43±9.89) ng/ml], prostate volume [(35.81±17.88) ml vs (34.37±16.56) ml], and PSA density [(0.44±0.37) ng/ml2 vs (0.50±0.43) ng/ml2] (P>0.05). Among the 593 patients included, 287 (287/593, 48.4%) had prostate cancer. The detection rate in the conventional group was 44.8% (143/319), and the detection rate in the CEUS group was 52.6% (144/274). There was no significantly difference in the total detection rate of prostate cancer between the conventional ultrasound group [44.8% (143/319)] and the CEUS group [52.6% (144/274)] (P>0.05). The detection rate of prostate cancer in subgroup A1 [31.9% (45/141)] was significantly lower than that of subgroup B1 [44.4% (48/108] (χ2=4.10, P=0.043), though the detection rate did not differ significantly between subgroup A2 [42.6% (46/108)] and subgroup B2 [47.8% (44/92)] and between subgroup A3 [74.3% (52/70)] and subgroup B3 [70.3% (52/74)] (P>0.05).
For patients with a PSA contentration of 4-10 ng/ml, CEUS-TB combined with SB can improve the detection rate of prostate cancer.
