目的 通过检测脑胶质瘤患者血清中胰岛素生长因子-1(IGF-1)和胶质纤维酸性蛋白(GFAP)的表达,探讨其与胶质瘤分级及预后评估的关系。 方法 2010年12月-2011年11月,采用双抗体一步夹心法分别测定A、B两组共40例不同级别脑胶质瘤患者术前、术后血清中IGF-1和GFAP浓度。 结果 高级别胶质瘤患者组血清中IGF-1浓度显著高于低级别胶质瘤组(P=0.009 0);血清GFAP浓度显著低于低级别胶质瘤组(P<0.000 1)。经手术治疗后且疗效评价为有效的胶质瘤患者,其血清中IGF-1、GFAP浓度较术前水平显著下降(P<0.001 0)。结论 IGF-1、GFAP是两种较好的脑胶质瘤血清标志物,在其分级及预后评估中具有重要的临床应用价值。
目的 探讨3D-多体素磁共振波谱(MRS)在评估脑胶质瘤手术切除程度的价值。 方法 对2011年6月-2012年4月32例脑胶质瘤患者术后行常规MRI及MRS检查,测定分析手术周边区域主要代谢产物N-乙酰天门冬氨酸(NAA)、胆碱(Cho)、肌酸(Cr)、Cho/NAA、Cho/Cr及NAA/Cr比值,对术后胶质瘤切除程度进行评价。同时通过术后病理检查结果评估肿瘤切除程度,再与MRS评估结果相比较。 结果 32例中病理评估为9例全切除,23例为大部分切除;MRS评估为11例全切除,21例为大部分切除,评估结果与术后病理评估结果差异无统计学意义(P>0.05)。 结论 MRS可以无创评价胶质瘤切除程度,为胶质瘤预后判定及进一步治疗提供了重要的依据。
目的 探讨脑胶质瘤术后不同时期的MRI增强表现,客观分析其术后的手术切除程度。 方法 2009年2月-2012年10月32例脑胶质瘤患者均在术后1 d~2周进行第1次MRI平扫及增强扫描(其中21例在术后3 d内进行检查),术后1~3个月随访复查21例,术后6~12个月随访复查18例,术后1~3年MRI随访16例。分析不同时期的MRI平扫及增强表现,以期发现正确评价手术切除程度的指标。 结果 术后3 d内行MRI增强检查仅有4例出现反应性强化,肿瘤残余有7例,结合其影像学表现可较准确地区分术后反应性强化及肿瘤残余。 结论 胶质瘤术后早期(3 d内)进行MRI增强检查可准确评价肿瘤术后切除程度,便于制订下一步治疗计划。
【摘要】 目的 探讨高级别胶质瘤患者放射、化学治疗后假性进展的临床特点、诊断与处理。 方法 分析2008年6月-2009年6月接受综合治疗的31例高级别胶质瘤患者临床资料,对假性进展的患者进行回顾分析,按照实体瘤疗效评判标准应用磁共振进行疗效评价。 结果 31例术后病理诊断为高级别胶质瘤的患者,替莫唑胺(TMZ)同期放射、化学治疗后维持TMZ辅助化学疗法,放射治疗后早期发生假性进展4例(14%)。 结论 对于TMZ同期放射、化学治疗后早期出现的影像学疑似进展,不要急于下结论,了解假性进展的临床特点,结合功能影像学检查可能会有助于临床医生的判断与处理。【Abstract】 Objective To discuss the clinical feature, diagnosis, and management of pseudoprogression after radiochemotherapy of high-grade glioma patients. Methods The clinical data of 31 high-grade glioma patients who underwent postoperative radiochemotherapy from June 2008 to June 2009 were reviewed. Pseudoprogression cases were analyzed. The treatment response was assessed through magnetic resonance imaging (MRI) according to the established response evaluation criteria in solid tumors. Results All the 31 high grade gioma patients received postoperative fractioned radiotherapy with concomitant TMZ chemotherapy, followed by TMZ maintenance chemotherapy. Four cases of pseudoprogression occurred after radiotherapy (14%). Conclusion Doctors should be careful in making early diagnosis for the suspected early progression after TMZ concomitant radiochemotherapy. It would be helpful for management to combine the clinical features of pseudoprogression with functional imaging technology.
【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.
