颅内生殖细胞瘤的放射治疗

放射治疗在颅内生殖细胞瘤的治疗中起重要作用,但传统放疗并发症较多。随着放疗技术的进步,降低颅内生殖细胞瘤并发症的发生率提高治愈率已成为可能,近年也不乏大宗、长时间观察病例报道,澄清了一些该病在放疗方面有争议的和处理不规范的问题。     

脑转移瘤的立体定向放射治疗

立体定向放射（ＳＲＴ）已历时４０余年，取得的成绩较常规外照射是显著的。脑转移癌的占尸检癌症病人的１０％￣２０％，对该病的治疗同原发脑瘤有许多不同之处。本文着重就脑转移瘤的ＳＲＴ的治疗进展情况作一综述，以期在病人的选择，放疗剂量，靶区的规划以及预后因素的分析等方面做一探讨。     

立体定向分次放疗联合全脑放射治疗脑转移瘤疗效分析

目的 分析X刀分次立体定向放疗(FSRT)联合全脑照射(WBRT)治疗脑转移瘤疗效。方法 回顾性分析51例脑转移瘤FSRT+WBRT和35例脑转移瘤单纯WBRT的结果,比较分析两者有效率、生存率的差异。结果 FSRT+WBRT、WBRT组完全缓解率分别为49%、26%(P<0.05),中位生存期分别为(11.0±1.5)、(6.5±0.5)个月(P<0.05),18个月生存率分别为24%、9%(P<0.05)。两组有效率(8%、71%,P>0.05)和6、12个月生存率(63%、41%,51%、23%,P>0.05)相似。 结论 X刀FSRT联合WBRT治疗脑转移瘤损伤小、安全、延长生存期,疗效优于单纯全颅放疗。     

立体定向分次放疗联合全脑放射治疗脑转移瘤疗效分析

Objective To evaluate efficiency of brain metastases tumor using X-knife under farctionational stereotactie radiotherapy (FSRT) combine with whole brain radiotherapy (WBRT). Methods Retrospective comparing 51 patients treated by FSRT plus WBRT (FSRT + WBRT group) with 35 patients treated by WBRT alone (WBRT group) on the effecting rate and survival rate. Results The completeness response rate was 49 % and 26 % (P < 0.05) in FSRT + WBRT and WBRT groups, respectively. The effecting rate was 80 % and 71 % (P 0.05) in FSRT + WBRT and WBRT groups, respectively.

颅内生殖细胞瘤放疗的研究进展

近几十年以来,颅内生殖细胞瘤的放疗方案基本都是基于全脑全脊髓或全脑室放疗,因此,患者具有较高的生存率。近年来对于放疗的研究主要集中于在保证疗效的情况下,尝试减少照射体积或强度,以求进一步减少放疗所带来的并发症。笔者回顾性总结了部分国内外学者在颅内生殖细胞瘤放疗方案的选择上所做的积极的探索与研究,以期为今后的临床工作提供一些思路与参考。     

脑立体定向等中心放射治疗

近年来,立体定向放射外科(stereotacticradiosurgery)作为一门新兴的学科,开辟了神经外科治疗领域的最新途径,除了γ-刀已得到公认的疗效之外,采用直线加速器或钴-60等普通放射源,在MRI、CT或DSA(数字减影脑血管造影)辅助的立体定向下进行等中心放射,同样可以达到γ-刀的效应,克服了

脑转移癌近距离放射治疗配合外照射治疗的临床分析

目的 探讨立体定向近距离放射治疗配合外照射治疗脑转移癌的方法及疗效。方法 自1994年4月～1999年4月，采用立体定向后装近距离放射治疗配合外照射治疗脑转移癌19例(均为肺癌恼转移，孤立或两个病灶)。近距离治疗剂量为25～35Gy／10～12次／7～10d。全脑外放疗剂量为30～40Gy／3～4周。结果 总缓解率为84．2％(16／19)。一年局部控制率为60．0％(6／10)。中位生存11个月。随诊期内未出现严重并发症。结论 近距离放射治疗配合外放疗能够改善脑转移癌病人的生存质量及生存期。不会增加严重放射性并发症的发生率。     

脑转移瘤立体定向放射治疗进展

MRI在脑转移瘤的诊断、治疗以及随访中有重要作用。原发灶状况、脑转移瘤的体积、立体定向放疗前后是否加全脑放疗、一般状况评分、回归分割分析(RPA)分级、是否存在颅外转移等是影响脑转移瘤治疗效果的主要因素。单纯立体定向放疗逐渐成为脑转移瘤治疗的主流．分次立体定向放疗在脑转移瘤治疗中的作用尚未完全明确。
