BACKGROUND/AIM: Multi-parametric magnetic resonance imaging (mpMRI)/ultrasonography fusion prostate biopsy (FB) is a more accurate method of diagnosis than conventional prostate biopsy, but false-positive lesions still exist. Limited studies have examined the cause of false-positive lesions by histological analysis.
We examined 322 patients who underwent mpMRI/transrectal ultrasonography (TRUS) FB. We classified prostate imaging-recording and data system (PI-RADS) 3 and PI-RADS 4-5 as low PI-RADS lesions and high PI-RADS lesions, respectively. In total, 105 lesions were identified as false-positive lesions. We performed histological analysis of atrophy, hyperplasia, and lymphocyte infiltration in these lesions, comparing low PI-RADS lesions and high PI-RADS lesions.
The frequencies of prostate hyperplasia and lymphocyte infiltration were higher in high PI-RADS lesions than in low PI-RADS lesions (p=0.028 and 0.024, respectively). There was no significant difference regarding atrophy (p=0.295).
Histopathological change may be one of the reasons for false-positive lesions.
背景/目的:多参数磁共振成像(mpMRI)/超声融合前列腺活检(FB)是一种比传统前列腺活检更准确的诊断方法,但仍存在假阳性病变。有限的研究通过组织学分析检查了假阳性病变的原因。
我们检查了 322 名接受 mpMRI/经直肠超声(TRUS)FB 的患者。我们将前列腺影像报告和数据系统(PI-RADS)3 和 PI-RADS 4-5 分别归类为低 PI-RADS 病变和高 PI-RADS 病变。总共确定了 105 个假阳性病变。我们对这些病变中的萎缩、增生和淋巴细胞浸润进行了组织学分析,并比较了低 PI-RADS 病变和高 PI-RADS 病变。
高 PI-RADS 病变中前列腺增生和淋巴细胞浸润的频率高于低 PI-RADS 病变(p=0.028 和 0.024)。萎缩无显著差异(p=0.295)。
组织病理学变化可能是假阳性病变的原因之一。
