高强度聚焦超声治疗前列腺癌的研究现状

The current investigation status of high intensity focused ultrasound treating prostate cancer

作为常见肿瘤的前列腺癌,其发病率逐年上升。手术是局限性病变的主要治疗手段,但仍然有一定的并发症和死亡率。放化疗等传统治疗手段也有其适应证和疗效的局限性,迫切需要有效的微创治疗方法。近年发展起来的高强度聚焦超声(HIFU)正日益受到人们的关注,对其作用机制、设备原理、适应证、治疗效果和局限性等问题作综述。

Being the common tumor forms,prostate cancer, its incidence is ascending year after year. Although surgery is the key treatment means in local prostate cancer, but the complications and mortality rate are frequently observed. Radiotherapy and chemotherapy, the traditional measures in prostate cancer treatment,are limited by the indication and relatively lower curative effect. So, needs to look for effective microinvasion treatments. As the new technique of microinvasion, high intensity focused ultrasound-HIFU, is remarkerablely noticed by people, in this paper, the mechanism ;equipment, clinical effect and limitation were summarized.
