  • 脑功能区胶质瘤手术策略的研究进展

    【摘要】 大脑功能区胶质瘤的手术治疗是神经外科临床工作非常棘手的问题。最大限度地切除病变、最大程度地保护功能区、避免术后神经功能缺失、提高患者术后生活质量,是脑功能区胶质瘤手术治疗的最高目标。术前功能神经影像、术中神经导航和超声、CT、MRI、肿瘤显色、电生理监测的应用,已成为当前脑功能区胶质瘤手术的重要策略。现就脑功能区手术策略的研究进行综述。

  • 实时荧光显像在胶质瘤术中应用的研究进展

    【摘要】胶质瘤是中枢神经系统发病率最高的恶性肿瘤,目前的治疗方法是以手术为主、放化疗为辅的分级分型个体化综合治疗,其中手术为最快速和有效去除肿瘤组织的手段。由于肿瘤常呈浸润性生长,术中肿瘤边界显示不清,要达到术中全切非常困难。提高肿瘤边界判断的准确性,以助于术者最大限度地切除肿瘤,便成为改善患者预后的主要方法。术中实时荧光显像技术为近年来蓬勃发展的判断肿瘤边界的新技术。目前国际上荧光显像方法主要有δ-氨基-γ-酮戊酸、荧光素钠、纳米荧光探针、靛氰绿、多光子激发荧光等引导的荧光显像法,前两者相对较成熟而后三者仍处于研究之中。本文就术中实时荧光显像在胶质瘤术中应用进行阐述。

  • Relationship between the Hormones Changes in Patients with Craniopharyngioma before the Surgery and Diabetes Insipidus after the Surgery

    【摘要】 目的 分析颅咽管瘤术前泌乳素(PRL)、促甲状腺激素(TSH)和促肾上腺皮质激素(ACTH)的变化,探讨术前激素变化与术后尿崩症的关系,为术后并发症的防治及预后的评估提供参考依据。 方法 对2003年3月-2007年6月收治的96例颅咽管瘤患者进行回顾性分析。对患者术前的激素(PRL、TSH及ACTH)检测结果与术后尿崩症的关系进行分析;按照术前有异常的激素种类将患者分为Ⅰ组(术前无激素的改变)、Ⅱ组(术前有任意1种激素发生改变)、Ⅲ组(术前有任意2种激素发生改变)及Ⅳ组(术前3种激素都发生改变)组。分析不同组别与术后尿崩症的关系。 结果 术前PRL、TSH及ACTH有改变的患者术后尿崩症发生率高于术前上述激素无改变的患者,PRL、TSH及ACTH发生改变的种类越多,术后尿崩症发生率越高。 结论 术前PRL、TSH及ACTH的改变和改变的种类多少可以作为判定术后并发症和评估预后的参考指标之一。【Abstract】 Objective To observe the changes of prolactin (PRL), thyroid stimulating hormone (TSH), and adrenocorticotropic hormone (ACTH) in patients with craniopharyngiomas before surgery; and to analyze the relationship between their changes and incipidus after the surgery to get the basis for postoperative complications and prognosis. Methods Ninety-six patients with craniopharyngiomas from March 2003 to July 2007 were seleted. The relationship between endocrine changes before surgery and diabetes insipidus after surgery was analyzed. The patients were divided into four groups:no endocrine changed in group Ⅰ, one hormone changed in group Ⅱ, two hormones changed in group Ⅲ, and all the three hormones changed in group Ⅳ. The relationship between different groups and diabetes insipidus was analyzed. Results The pre-operative endocrine abnormalities was the sign of hypothalamus injury. There were significantly higher incidences of diabetes insipidus after the surgery in patients with endocrine abnormalities than that in the patients without any endocrine changes. There were significantly different incidence of diabetes insipidus after the surgery in different groups. Conclusion The pre-operative endocrine changes can be the guideline to predict the postoperative diabetes insipidus and to evaluate the prognosis.

  • 胶质瘤术后假性进展的临床特点及治疗

    【摘要】随着对术后胶质瘤复发的不断研究,逐渐发现胶质瘤术后补充放疗和/或化疗等综合治疗的患者行MRI检查后出现类似肿瘤复发的强化影像,经病检证实为一种治疗相关反应,称之为“假性进展(pseu-doprogression,psPD)”。胶质瘤术后患者psPD与肿瘤复发有不同的病理生理机制及治疗方案,随着对psPD及胶质瘤复发认识的日臻完善,使得临床医生在判断复发胶质瘤及制定其治疗策略的过程中更为准确、有效。

  • 端粒长度调节酶1在脑胶质瘤中的研究进展

    脑胶质瘤是颅内最常见且最难治愈的肿瘤之一,目前尚缺乏特异性的诊断和预后生物学标志,因此,胶质瘤的诊断与治疗一直都是神经肿瘤领域的研究难点。端粒酶历来与肿瘤的研究密切相关,近几年研究发现端粒长度调节酶1(RTEL1)的基因突变,使其在脑胶质瘤中表达明显减少,可能与脑胶质瘤发生、发展以及预后密切相关,而在部分非颅脑肿瘤的研究中却发现RTEL1的表达结果与胶质瘤截然相反。现结合相关文献,就RTEL1的结构特性及在脑胶质瘤中的研究进展进行综述,希望对其在颅内肿瘤的诊断、鉴别诊断及预后中等提供一定的参考意义。

  • Assessment for Relevant Factors of Quality of Life in Adults with Surgically Managed Cerebral Supratentorial Low Grade Glioma (WHO Grade Ⅱ)

    【摘要】 目的 探讨成人幕上低级别胶质瘤(WHO Ⅱ级)患者术后生活质量的影响因素。 方法 回顾性分析2008年10月—2010年5月经手术切除病变、术后病理证实为低级别胶质瘤的115例患者临床资料,术后随访6~24个月。以患者年龄、性别、主要临床症状、病变部位、病变大小及病理结果为自变量,以术后Karnofsky评分(KPS)改善为因变量,采用Logistic回归分析研究相关影响因素。采用秩和检验比较不同组间KPS差异。 结果 随访至术后6个月,患者年龄、病变大小、病变部位、切除范围以及是否有癫痫史在KPS比较中,其结果有统计学意义(Plt;0.05)。随访至术后12个月,切除范围和癫痫史对KPS评分已无影响(Pgt;0.05)。病理类型、术前是否存在神经功能障碍与术后KPS改善在单因素和多因素比较中无统计学意义。 结论 患者年龄≤50岁、术前有癫痫史、肿瘤直径≤4 cm、病变表浅、肿瘤全切除的患者术后KPS改善好于年龄gt;50岁、术前无癫痫史、肿瘤直径gt;4 cm、病变深在、肿瘤次全切除的患者。患者术前是否存在神经功能障碍和病理类型与术后生活质量是否改善无明显关系。复发也是影响患者术后KPS改善的因素。【Abstract】 Objective To assess the quality of life in adults with surgically managed cerebral supratentorial low grade glioma (WHO grade Ⅱ) and the relevant factors.  Methods We retrospectively analyzed the clinical data of 115 patients with histologically proven supratentorial low grade glioma enrolled at West China Hosptial from October 2008 to May 2010. Follow-up lasted for 6 to 24 months after operation. Logisitc regression analysis is used to test the relevant factors with age, gender, main clinical manifestations, lesion location, lesion size and pathological results as the independent variables, and Kamofsky postoperative scale (KPS) scores as dependent variable. KPS scores of different groups were analyzed using the rank test.  Results After 6 months of follow-up, we found that age, size, location, extent of surgical excision and eplispy history showed a statistical significance in KPS comparison (Plt;0.05). Till the 12th month in the follow-up, the extent of surgical excision and eplispy history were not statistically significant any more (Pgt;0.05). Histology type and neurological deficit had no relationship with KPS improvement in both single factor analysis and multivariate analysis.  Conclusions Patients with an age older than 50 years, preoperative epilepsy history, the largest diameter of the tumor less than 4 cm, shallow lesions, and complete tumor resection have a better KPS improvement after operation than those with corresponding opposite conditions. There is no obvious relationship between histology type, neurologic deficits and KPS improvement after operation. Recurrence is also a factor influencing KPS improvement after operation.

  • Relationship between Aquaporin-4 and Vascular Endothelial Growth Factor in Cerebral Edema Induced by Gliomas

    目的 探讨水通道蛋白4(AQP4)在脑胶质瘤性脑水肿的分子调节机制及与血管内皮生长因子(VEGF)的关系。 方法 收集2007年10月-2008年6月间65例脑胶质瘤患者手术切除新鲜肿瘤标本(胶质瘤Ⅰ级6例、Ⅱ级18例、Ⅲ级11例、Ⅳ级30例)。应用免疫荧光细胞化学方法检测肿瘤组织中AQP4蛋白和VEGF蛋白的阳性表达情况,并分析AQP4和VEGF的表达差异与关系。 结果 免疫荧光细胞化学法染色显示,AQP4蛋白在正常脑组织中主要表达于细胞膜表面,胞浆和细胞核着色较浅。在胶质瘤细胞内,AQP4广泛分布于胞浆内;肿瘤中AQP4表达和VEGF呈正相关(r=0.877,P=0.000)。 结论 在胶质瘤性脑水肿中,AQP4在胶质瘤细胞内主要分布于胞浆内,且与VEGF呈明显正相关。
