Recently, multiparametric magnetic resonance imaging (mpMRI) and multiparametric ultrasound (mpUS) have been developed to improve prostate cancer (PCa) detection. This study aimed to investigate practice patterns and perceptions among clinicians regarding the use of mpMRI and mpUS as well as prostatic biopsies for PCa diagnosis.
We conducted a national survey via an online questionnaire among urologists, radiologists, and sonographers. The survey collected information on participants' knowledge, routine practices, and perceptions of prostate mpMRI and mpUS, as well as prostatic biopsies. Univariable and multivariable logistic regression analyses were used to identify specialists' characteristics associated with survey responses.
There were 354 responses from 144 hospitals were received. The majority (71.4%) of participants performed mpMRI for PCa diagnosis, while a small proportion (15.3%) of them used mpUS. The transperineal ultrasound-guided approach for systematic prostate biopsy was considered as preferable (47.2%). For targeted biopsy, cognitive fusion imaging (71.2%) and MRI-US fusion imaging (62.1%) were clearly favored. Compared with participants in community practices and from central-west region of China, those in academic practices and from east region of China were more likely to report utilization of mpMRI [odds ratio (OR) =2.08 and OR =0.19] and mpUS (OR =0.04 and OR =0.33) and recommendation of MRI targeted biopsy (OR =1.50 and OR =0.15) (P<0.05 in all).
The majority of specialists perceived that mpMRI was routinely used, while only a small proportion of them reported the use of mpUS in clinical practice. Participants in academic practices and from east region of China had greater self-reported use of mpMRI and mpUS and recommendation of MRI targeted biopsy.
近年来，多参数磁共振成像（mpMRI）和多参数超声（mpUS）已被用于改善前列腺癌（PCa）的检测。本研究旨在调查临床医生在使用mpMRI、mpUS以及前列腺活检进行PCa诊断方面的实践模式和看法。
我们通过在线问卷对泌尿外科医生、放射科医生和超声科医生进行了全国性调查。该调查收集了参与者关于前列腺mpMRI、mpUS以及前列腺活检的知识、常规做法和看法等信息。采用单变量和多变量逻辑回归分析来确定与调查结果相关的专家特征。
共收到来自144家医院的354份回复。大多数参与者（71.4%）使用mpMRI进行PCa诊断，而只有一小部分（15.3%）使用mpUS。经会阴超声引导下的系统性前列腺活检被认为是更可取的方法（47.2%）。对于靶向活检，认知融合成像（71.2%）和MRI-US融合成像（62.1%）明显更受青睐。与社区医疗机构以及中国中西部地区的参与者相比，学术医疗机构以及中国东部地区的参与者更有可能报告使用mpMRI（优势比[OR]=2.08和OR=0.19）和mpUS（OR=0.04和OR=0.33）以及推荐MRI靶向活检（OR=1.50和OR=0.15）（所有P<0.05）。
大多数专家认为mpMRI是常规使用的，而只有一小部分人报告在临床实践中使用mpUS。学术医疗机构以及中国东部地区的参与者自我报告使用mpMRI和mpUS以及推荐MRI靶向活检的比例更高。
