摘要
目的观察MRI引导目标穿刺活检(TB)诊断前列腺癌(PCa)的临床应用价值。方法对120例临床疑诊PCa患者行MRI,而后在经直肠超声(TRUS)引导下,分别采用系统穿刺(SB)与MRI定位行经会阴前列腺目标穿刺术(MRI-TB)。根据穿刺病理结果统计SB、MRI-TB及SB+MRI-TB对PCa检出率和穿刺阳性针率。结果病理诊断78例PCa,42例良性病变。SB、MRI-TB对PCa的漏诊率分别为23.08%(18/78)、8.97%(7/78),差异有统计学意义(P=0.048)。SB、MRI-TB及SB+MRI-TB对PCa的检出率分别为50.00%(60/120)、59.17%(71/120)和65.00%(78/120),SB+MRI-TB高于SB和MRI-TB(P均<0.05)。SB、MRI-TB及SB+MRI-TB的阳性针率分别为31.17%(374/1 200)、59.58%(286/480)及35.14%(538/1 531),MRI-TB高于SB和SB+MRI-TB(P均<0.001)。结论采用MRI-TB方案可提高穿刺阳性针率,减少穿刺点数,降低重复穿刺和并发症风险;联合应用SB+MRI-TB可提高PCa检出率。
Objective To explore the value of MRI located and transrectal ultrasound(TRUS)-guided transperineal biopsy of prostate cancer(PCa).Methods MRI were obtained of 120 patients with suspected PCa,and then systematic biopsy(SB)and MRI-located target biopsy(MRI-TB)guided by TRUS were performed.The detection rate for PCa and positive needle rate of SB,MRI-TB and SB+ MRI-TB were respectively calculated according to pathological outcomes.Results Seventy-eight PCa and 42 benign lesions were proved by pathology.The missed diagnosis rate of SB and MRI-TB for PCa was 23.08%(18/78)and 8.97%(7/78),which were statistically different(P=0.048).The detection rate of PCa for SB,MRI-TB and SB+MRI-TB was 50.00%(60/120),59.17%(71/120)and 65.00%(78/120),respectively,of SB+MRI-TB was higher than of SB and MRI-TB(both P<0.05).The positive needle rate of PCa for SB,MRI-TB and SB+MRI-TB was 31.17%(374/1 200),59.58%(286/480)and 35.14%(538/1 531),respectively,of MRI-TB was higher than that of SB and SB+MRI-TB(both P<0.001).Conclusion MRI-TB can improve the rate of positive biopsy needles,reduce the number of biopsy points and the risk of repeated biopsy and complications.SB+MRI-TB protocol can improve the detection rate of PCa.
