【摘要】：目的探讨MRI在氩氦刀冷冻治疗前列腺癌术后疗效评价中的价值。方法系统回顾2012年3月—2014年10月16例超声引导下氩氦刀冷冻治疗前列腺癌的临床及影像资料,分析术前术后实验室指标的变化,对比术前术后MRI资料,观察消融效果,包括有无术后残留、转移等。结果术后1个月MRI提示所有患者冷冻消融范围满意,均表现为长T2信号,DWI及DCE-MRI未见明显异常复发,前列腺特异性抗原(PSA)轻度下降。术后6个月MRI提示前列腺明显缩小,PSA明显下降,未见明显复发征象。术后无尿道坏死、尿道狭窄、尿道直肠瘘发生。1例患者随访6个月时因其他原因死亡。结论 MRI在评价氩氦刀低温冷冻治疗前列腺癌消融范围、术后复发或转移等疗效方面具有较好的临床应用价值。
[Abstract]:Objective to evaluate the value of MRI in the treatment of prostate cancer after cryotherapy with argon-helium knife. Methods the clinical and imaging data of 16 patients with prostate cancer treated by cryotherapy with argon-helium knife guided by ultrasound from March 2012 to October 2014 were reviewed systematically. The changes of laboratory indexes before and after operation were analyzed. The MRI data before and after operation were compared and the ablation effect was observed. Including postoperative residue, metastasis and so on. Results one month after operation, MRI showed that the range of cryoablation was satisfactory in all the patients, showing that there was no obvious recurrence on DWI and DCE-MRI with long T 2 signal intensity, and a slight decrease in prostate specific antigen (PSAs). Six months after operation, MRI showed that the prostate was significantly reduced and PSA was significantly decreased, but no recurrence was found. There was no urethral necrosis, urethral stricture and urethrorectal fistula. Conclusion MRI has a good clinical value in evaluating the range of ablation, recurrence or metastasis of prostate cancer by cryotherapy with argon-helium knife.
