高强度聚焦超声联合放疗、睾丸去势治疗前列腺癌的疗效观察

摘要

目的：探讨高强度聚焦超声（ HIFU）联合放疗、睾丸去势治疗前列腺癌的疗效。方法对38例已行放疗、睾丸去势治疗的前列腺癌进行HIFU治疗。结果15例（39％）前列腺特异性抗原（PSA）水平降至正常，20例（52％） PSA下降，2例（10％）仅症状缓解，有效率达92％。前列腺体积也明显缩小。结论 HIFU联合放疗、睾丸去势治疗前列腺癌，能有效控制肿瘤进展，为前列腺癌提供了1种新的有效治疗手段。%Objective To study the efficacy of high intensity focused ultrasound ( HIFU) combined with radiotherapy , testicular castration for prostate cancer .Methods 38 patients with prostate cancer who underwent radiotherapy and testicular castration were treated with HIFU.Results 15 cases (39%),prostate specific antigen (PSA) have fallen to normal,20 cases (52%) of the PSA declined,2 cases (10%) of symptoms relieved,effective rate was 92%.Prostate volume also narrowed con-siderably.Conclusion HIFU combined with radiotherapy and testicular castration can effectively control the progression of the tumor,it is a new effective treatment for prostate cancer .
