目的 探讨子宫颈癌四野照射合理铅块设计配合腔内治疗的更佳方法.方法 对39例各期子宫颈癌患者四野照射时超声测量子宫颈管至肿瘤外缘距离及妇科检查了解子宫旁情况,TPS计算四野照射时用同定铅块的放射治疗方法的子宫旁剂量,关注子宫旁的低剂量区.结果 四野照射时用固定铅块的放射治疗方法可能导致子宫旁的低剂量区,且肿瘤可能落在低剂量区内.39例患者中仍有29例见子宫旁不良改变,即肿瘤可能落在低剂量区内.结论 使用等中心技术个体化设计四野照射时的中线屏蔽铅块,能更好地消除子宫旁的低剂量区.
目的 探討子宮頸癌四野照射閤理鉛塊設計配閤腔內治療的更佳方法.方法 對39例各期子宮頸癌患者四野照射時超聲測量子宮頸管至腫瘤外緣距離及婦科檢查瞭解子宮徬情況,TPS計算四野照射時用同定鉛塊的放射治療方法的子宮徬劑量,關註子宮徬的低劑量區.結果 四野照射時用固定鉛塊的放射治療方法可能導緻子宮徬的低劑量區,且腫瘤可能落在低劑量區內.39例患者中仍有29例見子宮徬不良改變,即腫瘤可能落在低劑量區內.結論 使用等中心技術箇體化設計四野照射時的中線屏蔽鉛塊,能更好地消除子宮徬的低劑量區.

Objective To study more reasonable method of radiation barrier for cervical cancer treated with external radiation. Methods The distance from cervical canals to tumor's margin in x axis was measured by B ultrasonic, around uterus were evaluated by physical examination.and the dose around uterus for patient who used fixed lead brick for radiation barrier when treated with external radiation were calculationed by TPS, in 39 case of cervical cancer treated with external radiation combine with intracavitary irradiation. Pay attention to the lower dose area around uterus. Results It might bring about lower dose area around uterus who used fixed lead brick for radiation barrier when treated with external radiation,and mass might be in above area. Conclusion Cervical cancer treated with external radiation with source axial distance (SAD), and radiation barrier with lead brick individuate may help for to avoid the lower dose area around uterus.
