| 摘 要： | 目的探讨在经直肠前列腺超声引导下徒手对前列腺穿刺活检诊断前列腺良恶性病变中的临床价值。方法选取2019年2月~2020年1月在中国科学技术大学附属第一医院南区就诊的临床疑似前列腺癌并行经会阴前列腺穿刺活检患者62例，依最终病理结果分为2组：前列腺癌组，共25例，男性，年龄55~82岁；前列腺良性病变组，共37例，男性，年龄54~83岁。经直肠超声分别观察记录两组前列腺大小、内部回声及有无异常回声、回声大小范围，并按部位系统穿刺及目标靶向性穿刺，对比分析两组间临床资料以及前列腺病变特征。结果前列腺癌组病理类型均为前列腺腺癌（包括腺泡癌），良性病变组患者病理提示正常前列腺组织、腺体及间质增生、肌肉以及纤维组织。前列腺癌组穿刺取得组织中共145条病理结果为前列腺癌，108条（75%）位于前列腺周缘区穿刺点，癌组织占比标本组织长度大于50%的有81条（56%）。经直肠超声共发现52个异常回声，均穿刺取得病理，对比分析发现不同大小的低回声其病理成分不同，差异有统计学意义（P < 0.05）。结论经直肠超声引导下经会阴前列腺穿刺对前列腺周缘区有优势性并可对可疑病变区域直观准确的目标性穿刺，对于前列腺良恶性病变的诊断具有重要意义。

| Abstract: | ObjectiveTo explore the clinical value of prostate biopsy in diagnosing benign and malignant prostate lesions under the guidance of TRUS.MethodsFrom February 2019 to January 2020, 62 patients with clinically suspected prostate cancer who underwent transperineal prostate biopsy in our Hospital were included. The patients received a freehand transperineal biopsy of the prostate. According to the pathological results, the patients were divided into two groups. The prostate cancer group(25 cases, males, 55-82 years old) and prostatic hyperplasia group (37 cases, males, 54-83 years old). The prostate size, abnormal echoes, systematic biopsy and targeted biopsy were recorded. The ultrasonographic features were compared between two groups.ResultThe pathological types of prostate cancer group were prostate adenocarcinoma (including acinar carcinoma). The prostatic hyperplasia group showed normal prostatic tissue, gland and interstitial hyperplasia, muscle and fibrous tissue. A total of 145 needle malignant tissues were obtained by puncture in prostate cancer group, and 108 needle (75%) were located in the prostatic peripheral zone. There were 81 needle tissues which malignant tissue accounting for more than 50% of the tissue length. A total of 52 abnormal echoes were found by TRUS. The sizes of abnormal echoes and pathological components were significant different between 2 groups.ConclusionTRUS-guided transperineal biopsy has advantages over the prostatic peripheral zone. It can directly and accurately puncture the suspected lesion area, and make it important for the diagnosis of benign and malignant prostatic lesions. |
