新后装技术在宫颈癌腔内治疗中的应用

目的探讨新(核通)后装治疗技术在宫颈癌腔内放射治疗的应用效果。方法比较新(核通)旧(威达)后装治疗机在放射治疗后的毒性反应、局部控制率、生存率。结果新后装机治疗后1年患者的局部控制率明显优于旧后装机治疗组(χ2=4.351,P0.05),直肠、膀胱、盆腔的毒性反应也明显小于旧后装机治疗组(χ2=5.529,P0.05)。结论新(核通)后装机腔内放射治疗能改善靶区和正常组织受照剂量的关系,降低了不良反应,提高了局部控制率。

After the new technology application in cervical cancer cavity treatment

Objective Discuss the new （nuclear tong） after treatment technology in the body cavity cervical cancer radiotherapy problems in application . Methods Relatively new （nuclear） old（vectra） after loading therapy appa-ratus after radiotherapy toxicity reaction ,local control ,survival rates . Results The new installed after 1 year af-ter treatment of installed after local control is superior to the old ;rectum ,biadder and pelvic cavity are less toxic re-action and reaction produced by oid installed after treatment （χ2 =4.351 ,P＆lt;0.05 ;χ2 =5.529 ,P＆lt;0.05） . Con-clusion Nuclear tong installed cavity after radiation therapy can improve the target area and the normal tissue dose illuminated ,reduce the adverse reaction ,to improve the local control .
