摘要
目的 了解近十年来我国乳腺癌放射治疗的变化及发展趋势.方法 对东南沿海地区4所医院,在1999年和2006年因乳腺癌接受放射治疗患者的临床特点、治疗目的 、放疗技术等内容进行调查.结果 2006年接受保乳治疗（BCT）患者占全部乳腺癌放疗患者的13%,而1999年只有3%.与1999年相比,2006年有明显增加的内容有：采用乳腺专用体架固定（80%和46%）、CT模拟定位（14%和O%）、治疗计划系统剂量计算（70%和23%）、根治性手术后胸壁照射（90%和67%）;而腋窝和内乳淋巴区受到照射的比例明显减少,分别是37%和69%及30%和76%;总剂量与分次方式则没有不同.结论 接受保乳治疗的患者虽有较明显增多,但在我国目前仍以根治性手术后放射治疗为主.较先进放疗设备与技术的应用明显增加,但在模拟定位、治疗计划设计、照射靶区选择等方面有待进一步提高.
Objective To explore the changes and the tendency of breast cancer radiotherapy in China within the past decade.Methods A survey on breast cancer radiotherapy in 1 999 and 2006 was conducted in 4 hospitals located within the southeast coastal region of China,including patients＇clinical characteristics,the purpose of radiotherapy and its techniques.Results The percentage of breast conservative treatment（BCT）increased from 3%in 1999 to 13%in 2006.For radiotherapy techniques in 2006 compared with 1999,the growth trend was found in use of breast immobilization devices（80% vs.46%）,treatment planning system（70% vs.23%）,and CT simulation（14%vs.0）.The frequency was increased in the chest wall irradiation after masteetomy（90%vs.67%）,but decreased in internal mammary region（30%vs.76%）and axilla（37%vs.69%）treatment.There were no differences in total dose and fractionation prescription.Conclusions BCT was performed more frequently,but postmastectomy radiotherapy was still essential option in China at present.Although some advanced techniques were applied frequently in clinical practice.Simulation,treatment planning,and irradiation target design were urgent for improvement and standardization.
