乏血供HCC，gamma刀后二月复查MRI提示肿瘤进展，此期二月未采用其它治疗手段（只吃保肝药）。

沈阳军区总医院也有一台TOMO啦，我就是做的这个，效果还是不错的

脑部放疗，上午比下午敏感许多！

Abstract
% s3 ]3 V: u; s- _BACKGROUND: Circadian cell-cycle progression causes fluctuating radiosensitivity in many tissues, which could affect clinical outcomes. The purpose of this study was to determine whether outcomes of single-session gamma knife radiosurgery (GKRS) for metastatic nonsmall cell lung cancer (NSCLC) differ based on treatment time.

; o& I7 a4 F3 h* LMETHODS: Fifty-eight patients received GKRS between 10:00 am and 12:30 pm and 39 patients received GKRS between 12:30 pm and 3:00 pm. The mean peripheral dose was 18.6 Gy. The mean tumor size was 7.3 cm³. Magnetic resonance imaging was used to score local control at 3 months. Cause of death (COD) was categorized as central nervous system (CNS)-related or systemic.

* J; p; v2 Z% G7 _' n5 WRESULTS: Demographic and disease characteristics of the 2 groups were similar. Local control at 3 months was achieved in 97% (35/36) of patients who underwent GKRS early in the day versus 67% (8/12) of patients who underwent GKRS later in the day (chi-square, P = .014). Early GKRS was associated with better survival (median 9.5 months) than late GKRS (median 5 months) (Kaplan-Meier log-rank test, P = .025). Factors contributing to better survival in a Cox regression model included early treatment time (P = .004) and recursive partition analysis class (P < .001). Cause of death in the early treatment group was CNS-related in 6% (3/47) of patients versus 24% (8/34) of patients in the late treatment group (chi-square test, P = .026).

1 M! [' F; z6 T' ]2 v' QCONCLUSIONS: GKRS for metastatic NSCLC had better local control, better survival, and a lower rate of CNS-related cause of death when given earlier in the day versus later in the day. These retrospective data should encourage future study in brain radiosurgery and non-CNS stereotactic body radiotherapy series.

我们打算做伽马刀

$ S5 @. M6 k9 u" a4 x) Y  X2 Y千万不要做伽马刀，这已经是几乎被淘汰的技术，我父亲治病时候两个病友，肺转移，都是做完伽马刀以后病情恶化很快就走了，一定要做放疗，建议做射波刀和TOMO，虽然价格相对伽马刀高昂很多，但无论从疗效精确度还是病人的副反应来说，都远胜伽马刀

我本人于2011年6月，因为头部核磁观察，原有疑似单发病灶有水肿，医生建议做头部X刀治疗，做一个头部面部磨具，当时是两天做一次，我一共照射了五次，没有任何不适感觉，治疗后至今稳定，我本人考虑头部或许不是转移病灶。

我刚做了伽马刀不久现状况还好

不错顶
