目的探讨陀螺旋转式钴60放射外科治疗系统治疗腹膜后淋巴结转移瘤的近期疗效.方法 32例腹膜后淋巴结转移患者,给予陀螺旋转式钴60放射外科治疗系统治疗,50%~70%等剂量曲线覆盖整个靶区,单次周边剂量给予3~5Gy,周边总剂量35~50Gy.结果 32例中完全缓解(CR)24例,部分缓解(PR)7例,无变化(SD)1例.总有效率(CR+PR)为97.0%.多因素分析显示原发病、放疗剂量、症状缓解影响预后,而淋巴结转移大小、是否有癌栓、放疗体积与预后无关.结论陀螺旋转式钴60放射外科治疗系统(简称陀螺刀)治疗腹膜后淋巴结转移瘤安全有效,可作为腹膜后淋巴结转移瘤的辅助性治疗手段.

@@@@ Objective To analyze the clinical observation of treatment of retroperitoneal lymph node metas -tasis by the radiation therapy of gyro rotary 60 cobalt radiation treatment system.Methods Thirty two patients with retro-peritoneal lymph node metastasis were treated with stereotactic radiotherapy in our department .The dose was 3~5Gy per fraction,the total dose of retroperitoneal were ranged from 35Gy to 50Gy,five times a week.The planned target volume was encompassed by more than 50%to 70%isodose line.Results The overall response rate(CR+PR) was 97.0%. Multivariate analysis showed that original illness ,radiotherapy dose and partial and complete response were related to i-dentified predictors of outcome,and the volume of radiotherapy,the size of metastatic-lymph node and tumor thrombi were not related to the outcome.Conclusion The radiation therapy of gyro rotary 60 cobalt radiation treatment system is a safe and effective treatment for retroperitoneal lymph node metastasis .It can be used as adjuvant therapy with the radia-tion therapy of gyro rotary 60 cobalt radiation treatment system .
