CT导向下多极射频消融治疗前列腺癌

目的探讨CT导向下多极射频消融治疗术在前列腺癌治疗中的意义。方法本院22例前列腺癌患者，均经会阴前列腺穿刺活检病理证实为前列腺腺癌。临床分期（2002AJCC分期）：T1C N0M0 14例，T2MC N0M0 8例。所有患者均在完成术前准备后于CT导向下行多极射频消融治疗，对于病灶在4．0cm以下者，消融治疗时间10min或更短；4．1cm以上者，治疗时间延长至15min或更长时间，并酌情行多位点叠加治疗。结果22例患者，显效11例，有效9例。稳定2例。并发症和不良反应包括发热（22／22）、血尿（1／22）、尿路刺激征（3／22）及局部血肿（1／22），经对症治疗后均可得到恢复和缓解。结论CT导向下多极射频消融治疗是一种安全、有效的治疗前列腺癌的方法。

CT-guided percutaneous multipolar radiofrequency ablation for carcinoma of prostate

Objective To evaluate the value of CT-guided percutaneous muhipolar radiofrequency ablation therapy for carcinoma of prostate. Methods The retrospective analysis was undertaken in 22 patients. All the cases were confirmed by pathology of punctured biopsy. Clinical Staging （2002 AJCC staging） ： T1CN0M0： 14 cases, T2MCN0M0 8 cases. All the patients were treated by CT-guided percutaneous muhipolar radiofrequency ablation therapy after the preoperative preparation. To the nodules of which the diameter was below 4.0 cm, the time of therapy was 10 min or shorter, to the nodules larger than 4. 1 cm, the time was 15 min or longer, and adopted muhipoint therapy when it was necessary. Results All the 22 patients, 11 showed excellence, 9 showed effective, and 2 were stable. The complication and adverse reactions included： fever （22/22）, hematuria （1/22）, urinary irritation symptoms （3/22）, and local hematoma （1/22）, all of which were recovered and released after symptomatic treatment. Conclusion CT-guided percutaneous multipolar radiofrequency ablation therapy is a safe and effective method for carcinoma of prostate.
