目的 :探讨二维超声在宫颈癌的诊断和放疗疗效观察中的价值。方法 :对宫颈癌治疗前进行超声诊断及分期 ,使用高剂量率近距离放疗治疗机进行腔内放疗与体外近距离放疗穿插进行。结果 :本组 36例均在病理诊断前超声提示宫颈癌 ,根据声像图表现分为 3期 ,Ⅰ期 5例 ,Ⅱ期 18例 ,Ⅲ期 13例。放疗后检查Ⅰ期 5例、Ⅱ期 18例、Ⅲ期 3例均达到临床治愈 ,Ⅲ期 6例宫颈接近正常大小 ,盆腔淋巴结消失 ,Ⅲ期 4例因累及其它器官效果不明显。结论 :①二维超声诊断宫颈癌准确性高 ,操作简便 ,重复性好 ;②了解确定宫颈大小 ,局部扩展和远处转移情况等有其独特的优越性 ;③判定192 铱放疗效果 ,方法简便、准确、对照射的次数和总剂量有重要的指导作用
Objective: To investigate the value of two-dimensional ultrasound in the diagnosis of cervical cancer and radiotherapy. Methods: Ultrasound diagnosis and staging of cervical cancer before treatment, high dose rate brachytherapy machine for intracavitary radiotherapy and brachytherapy in vitro. Results: All the 36 cases were diagnosed with cervical cancer before the pathological diagnosis. According to the sonographic findings, they were divided into three stages: stage Ⅰ in 5 cases, stage Ⅱ in 18 cases and stage Ⅲ in 13 cases. After radiotherapy, there were 5 cases in stage Ⅰ, 18 cases in stage Ⅱ and 3 cases in stage Ⅲ. All the 6 cases in stage Ⅲ were close to the normal size, the pelvic lymph nodes disappeared and the others in stage Ⅲ were not obvious. Conclusion: ①Two-dimensional ultrasonography diagnosis of cervical cancer with high accuracy, easy operation, good reproducibility; ② understand the size of the cervix, local expansion and distant metastasis has its unique advantages; ③ 192 iridium radiotherapy to determine the effect of the method is simple , Accurate, the number of irradiation and the total dose has an important guiding role
