目的评价经直肠超声引导下前列腺穿刺活检对前列腺癌病理分级的评估作用。方法156例患者,经临床检查及经直肠前列腺穿刺活检病理证实为前列腺癌,由二位有经验超声医师双盲读片,分析前列腺癌的声像图与病理分级之间的关系。结果156例前列腺癌经直肠前列腺穿刺点1014点,阳性穿刺点为660针,阳性率为65．05％,平均每个前列腺癌病人的阳性穿刺点为(4．23±1．73)。不同级别的前列腺癌的声像图具有不同的声像图表现。其中前列腺癌Ⅰ级以非典型性改变为主,夹有低回声结节。前列腺癌Ⅱ级以低回声肿块为主,伴有血流信号浓聚。前列腺癌Ⅲ级以弥漫型低回声病变,可伴有簇状钙化灶及前列腺不对称性肿大。结论经直肠超声引导下前列腺穿刺活检有利于前列腺癌的诊断,超声声像图对判断病理分级有一定作用。
Objective To evaluate the role of transrectal ultrasound-guided prostatic biopsy in the evaluation of the pathological grade of prostate cancer. Methods A total of 156 patients were diagnosed as prostate cancer by clinical examination and transrectal prostate biopsy. Two experienced ultrasound physicians double-blind readings were performed to analyze the relationship between the sonography of the prostate cancer and the pathological grade. Results Of the 156 prostate cancer patients, 1014 were transrectal prostatic punctures and 660 were positive puncture points. The positive rate was 65.05%. The average prostatic puncture point per prostate cancer patient was (4.23 ± 1.73). Echographs of different grades of prostate cancer have different sonographic appearances. Prostate cancer which level Ⅰ to atypical changes, with hypoechoic nodules. Prostatic cancer with low echo mass Ⅱ-based, accompanied by blood flow signal concentration. Prostate cancer with diffuse hypoechoic grade Ⅲ may be associated with cluster calcification and enlarged prostate asymmetry. Conclusions Transrectal ultrasound-guided prostatic biopsy is helpful for the diagnosis of prostate cancer. Ultrasonography has a certain effect on pathological grading.
