Objective We searched and reviewed medical evidence to find the guide of treatment for local advanced nasopharyngeal carcinoma. Methods Firstly, we put forward clinical questions. Secondly, we searched medical evidence from Medline (1985-2002), Embase (1984-2000), Cochrane library (2002.1) and ACP. And then we reviewed the results. The key words we used were "nasopharyngeal carcinoma, chemotherapy and radiotherapy randomized" and "meta analysis or randomized control trial". Results Through searching, we got 17 papers including 1 systematic review and 16 randomized control trials, in which there were 8 prospective randomized phase Ⅲ trials. Most of these trials concluded that combination chemo-radiotherapy were better than radiotherapy alone. We think these results were suitable for our patient’treatment decision. Conclusion To treat our patients,we choosed the method of the mutimodality of squeitial neoadjuvant chemotherapy, concurrent chemo-radiotherapy and adjuvant chemotherapy with the drug doses down-adjusted.
【摘要】 目的 利用不同匹配区域对锥形束CT(CBCT)与定位CT(FBCT)分别配准,测量出鼻咽癌放射治疗中颈部的变形误差。 方法 分析2007年4月-2008年12月收治鼻咽癌患者23例,调整治疗床前198次CBCT扫描。将鼻咽部扫描CBCT图像匹配区域分为上下两个区域进行对比分析。其中上匹配区域为:上界为蝶窦上缘,下界为颈4下缘,侧界包括下颌骨外轮廓,前界为上颌窦1/2,后界为平棘突后缘;下匹配区域为:上界约颈4下缘,下界约胸2-3下缘,侧界包括椎体外轮廓,前界包括皮肤,后界平棘突后缘。匹配方式选择骨,比较匹配结果差异。 结果 选择上与下匹配区域结果除Y(头脚)方向旋转误差无统计学差异外,余均有统计学差异(Plt;0.05) 。差值在X(左右)、Z(前后)、Y(头脚)方向平移分别为(1.14±2.80)、(0.47±1.41)、(0.58±3.88) mm,旋转误差X、Y、Z方向分别为(0.90±1.98)、(0.80±2.03)、(0.68±1.90)°。 结论 鼻咽癌放射治疗中颈部区域存在一定变形误差,通过CBCT引导发现变形误差并进行正确纠正是必须的,结合临床实际及靶区与危及器官的变化为重新计划提供依据。【Abstract】 Objective To investigate the rotation errors due to neck deformation in nasopharyngeal cancer (NPC) radiotherapy with different match areas to register conebeam CT(CBCT) from image guiding and fanbeam (FBCT) from simulation. Methods A total of 198 pre-correction CBCT data sets from 23 NPC patients from April 2007 to December 2008 were retrospectively analyzed. The matching areas in CBCT images were divided into up and down region of interest (ROI). For the up ROI, the superior, inferior, left and right, anterior, and posterior boundary were set parallel with sphenoid sinus up side, C4 down side, mandible outside, and 1/2 of maxillary air sinus and acanthi. For the down ROI, the lines were set parallel with C4 down side, T2-3 down side, neck outside, skin surface and acanthi respectively in all directions. All registrations were performed automatically by bony anatomy and the results were compared. Results The registration results by the up and the down ROI showed significant difference except Y direction for rotation. The translation error was (1.14±2.80),(0.47±1.41),and (0.58±3.88) mm, respectively; and the rotation error was (0.90±1.98),(0.80±2.03),and (0.68±1.90) ° in X, Y, and Z direction, respectively. 〖WTHZ〗Conclusions〖WTBZ〗There are some significant deformation errors at neck areas in NPC radiotherapy. It is important to find out the deformation and correct it with CBCT image guiding. This kind of error information may provide clues for re-planning in addition to clinical practice and the changes of clinical targets and involved organs.
目的 检测血管内皮生长因子(VEGF)、白细胞分化抗原34(CD34)及CXC趋化因子受体4(CXCR4)在转移性鼻咽癌患者鼻咽部肿瘤组织中的表达,探讨它们与鼻咽癌各种临床病理因素的关系以及它们之间的相互联系。 方法 采用免疫组织化学链霉素抗生物素蛋白-过氧化物酶连结法检测2003年3月-2009年5月35例转移性鼻咽癌患者VEGF、CD34及CXCR4在鼻咽部肿瘤组织中的表达情况,结合患者临床病理特征进行分析。 结果 转移性鼻咽癌患者鼻咽部肿瘤组织中的VEGF及CXCR4阳性表达率分别为62.9%(22∕35)和42.9%(15∕35),CD34计数为11~92,平均43.2 ± 20.5。无肺转移较有肺转移的患者VEGF的阳性表达率高(78.9%、43.8%,P=0.043),多器官转移较单器官转移的患者CXCR4的表达强度高(62.5%、26.3%,P=0.044)。 结论 VEGF表达阳性的患者易发生肺转移;CXCR4强表达的患者易发生多器官转移。
【摘要】 目的 评价中药复方(益气养阴、清热活血方Yiqi Yangyin Qingre Huoxue decoction,YYQHD)联合放射疗法治疗鼻咽癌在减毒增效方面的疗效。 方法 采用Cochrane系统评价方法,电子检索Cochrane图书馆临床对照试验资料库(Cochrane Central Register of Controlled Trials,CENTRAL)、PubMed、EMBASE、中国生物医学文献数据库(CBM)、中文科技期刊全文数据库(CNKI)和中国期刊全文数据库(VIP)以及万方数据库等数据库2010年3月前所发表的相关文献。同时互联网检索Current Controlled Trial、Clinical Trials和中国临床试验注册网。手工检索部分肿瘤类核心期刊。采用Cochrane协作网推荐的 “偏倚风险评估”工具,评估纳入研究的质量,使用RevMan 5.0.23.0软件对纳入的研究进行定量系统评价。 结果 最终纳入符合标准的中文文献9篇共795例患者。定量分析结果显示:与单纯常规放射治疗相比较,中药复方(YYQHD)联合常规放射治疗能显著提高肿瘤近期疗效、生存率,并且能显著减少放射治疗常见毒副反应的发生,从而提高放射治疗按时完成率确保放射治疗疗效、改善患者生存质量。 结论 虽现有研究尚不能得出可以将中药复方(YYQHD)作为标准治疗手段辅助放射治疗的结论,但提示益气养阴、清热活血类中药联合放射治疗治疗鼻咽癌是值得继续探索的研究方向,期待设计科学合理、高质量的多中心、大样本、双盲、随机对照临床试验以进一步验证其疗效。【Abstract】 Objective To compare the efficacy of traditional Chinese medicine (TCM) plus radiotherapy (RT) with RT alone on nasopharyngeal carcinoma (NPC) by Yiqi Yangyin Qingre Huoxue decoction (YYQHD) through a meta-analysis of all available randomized controlled trials. Methods Literature retrieval was conducted using the Cochrane Library, PubMed, EMBASE, CBMdisk, CNKI, VIP, and Wanfang Database electronically. Relevant journals and conference proceedings were also hand-searched until March 31, 2010. The quality of included studies was assessed according to the criteria recommended by the Cochrane handbook, and the Meta-analysis was performed for homogeneous studies using RevMan 5.0.23.0 Software. Results Basing on our search criteria, we found nine trials (795 patients) which all published in Chinese. Our results showed that TCM (YYQHD) plus RT compared with RT alone, improved immediate tumor response, survival, completion rate of RT, quality of life, and alleviation of adverse effect of patients with NPC. Conclusions Considering the limitations related to this Meta-analysis, it nevertheless presents credible evidence that TCM (YYQHD) plus RT is worthy of additional study. Therefore, further large-scale, muti-center, randomized, and double-blind trials are warranted.
【摘要】 目的 观察时辰化学疗法联合放射治疗对比常规化学疗法联合放射治疗对鼻咽癌的近期疗效及其不良反应。 方法 2006年2月-2010年3月经病理学证实未接受过化学疗法的38例晚期鼻咽癌患者随机分为常规化学疗法联合放射治疗组(A组,n=20)和时辰化学疗法联合放射治疗组(B组,n=18)。两组均采用常规二维放射治疗。A组化学疗法方案为顺铂(DDP)80 mg/m2,采用完全水化方案,第1天静脉滴注;氟尿嘧啶800 mg/(m2•d),第2~6天120 h连续静脉滴注。B组时辰化学疗法采用Melodies多通道编程输液泵进行正弦曲线式时间调节给药。两组均为DDP 80 mg/m2,于10:00~22:00给药,浓度高峰设定在16:00;氟尿嘧啶800 mg/m2,于22:00~次日10:00给药,浓度高峰设定在凌晨4:00。每21天重复1次,行2~6疗程。 结果 A组3程化学疗法后有效率(PR)为95%(19/20),全程结束完全缓解率(complete remission,CR)达75%(15/20);B组在2程化学疗法后PR达100%,全程治疗结束CR达94.4%(17/18)。两组不良反应主要为迟发性血小板减少,发生率分别为35%(7/20)和22.2%(4/18),其他不良反应两组间无明显差别。 结论 时辰化学疗法联合放射治疗对晚期鼻咽癌在减轻化学疗法造成的血小板减少方面有明显的优势,值得临床推广应用以及进一步发掘时辰化学疗法在临床治疗的价值。【Abstract】 Objective To investigate the efficacy and the adverse effects of routine chemotherapy and chrono-chemotherapy combined with radiotherapy for advanced nasopharyngeal cancer patients. Methods From March 2006 to March 2010, 38 patients diagnosed pathologically to have advanced nasopharyngeal cancer were randomly divided to the routine chemotherapy and radiotherapy group (group A, n=20) and the chrono-chemotherapy and radiotherapy group (group B, n=18). Patients in both groups received bi-dimensional radiotherapy. Patients in group A received a full hydration method, cisplatin (DDP) 80 mg/m2 intravenous infusion was also carried out on day 1; fluorouracil 800 mg/(m2•d) chemotherapy, and 120 hours of continuous intravenous infusion from day 2 to day 6. For patients in group B, Melodies multi-channel infusion pump programming to adjust the time of drug administering with a sinusoidal style was adopted; DDP 80 mg/m2 was administered intravenously on day 1 between 10:00 and 22:00 with the peak concentration set at 16:00; fluorouracil 800 mg/m2 was administered between 22:00 and 10:00 on the next day from day 2 to day 6 with the concentration peak set at 4:00. The treatments in both groups were repeated every 21 days, which was repeated for two to six courses of tremtment. Results After three courses of treatment for group A, partial response (PR) rate was 95% (19/20), and after six courses of treatment, the complete remission (CR) rate was 75% (15/20); After two courses of treatment for group B, the PR rate was 100%, and after six courses of treatment, the CR rate was 94.4% (17/18). The main adverse effect was thrombocytopenia at an incidence rate of 35% (7/20) and 22.4% (4/18) in the two groups respectively. There was no obvious difference in other adverse effects between the two groups. Conclusion Chrono-chemotherapy combined with radiotherapy for advanced nasopharyngeal carcinoma has obvious advantages in reducing thrombocytopenia caused by chemotherapy, and it is worth further exploring the clinical applications and values of chrono-chemotherapy.
