摘要
目的 评价X 刀治疗肝癌的价值。方法 从 1999年 8月至 2 0 0 1年 12月采用X 刀治疗肝癌病人 40例 ( 11例原发肝癌 ,2 9例肝转移癌 ) ,采用 6～ 7个照射野进行照射 ,90 %剂量线包括计划靶区 (PTV) ,每周三次 ,每次 5～ 9Gy(平均 7Gy) ,总剂量从 2 5～ 5 0Gy(平均 40 2Gy)。结果 在所有的病人中 ,症状不同程度减轻 ,CR 3 2 5 %、PR 45 %、NC 12 5 %、PD 10 %,在 12个月的随访中 ,3、6、9、12个月生存率分别为 95 %、67 5 %、45 %和 2 7 5 %。结论 X 刀治疗肝癌是一种较好的方法 。
Objective To assess the therapeutic response in liver cancer patients treated by stereotactic radiosurgery Methods From Aug 1999 to Nov 2001, 40 Patients with liver cancer (11 primary and 29 metastatic were treated) They were irradiated by 6～7 port technique in different plans with SAD 90% of iso-dose curves covered the planning target volume (PTV) The stereotactic radiosurgery offered 5～9Gy (average 7Gy) per fraction, with the total dose ranging from 25 to 50 Gy (average 40 2Gy) Results: In all the 40 patients, the subjective symptoms were alleviated to certain extent or the appeared short_term observation showed: CR 32 5%? PR 45%? NC 12 5% and PD 10% During the 12 months of follow up the 3?6?9?12 month survival rate were found to be 95%?67 5%?45%?27 5%, respectively Conclusion The stereotactic conformal radiosurgery of liver cancer is better than the conventional local treatment It can be well tolerated by patients and is well worthy of recommendation
