  • Diagnostic and Therapeutic Considerations of Skull Hemangioma in Children

    目的:探讨儿童颅骨血管瘤的临床特点和手术治疗。方法:报告自2002年1月至2008年12月我院收治的3例儿童颅骨血管瘤病例,结合相关文献分析该疾病的临床表现,影像学特征,病理特点及治疗方法。结果:儿童颅骨血管瘤临床上极为罕见。影像学检查显示颅骨呈蜂窝状溶骨性改变并向颅内外生长。病理切片显示骨结构异常,并伴有大小不等异常血管增生及血栓形成。结论:颅骨血管瘤是一种侵蚀颅骨内外板的破坏性疾病。手术应早期进行,完整切除后,患者预后良好。

  • Clinical features and treatment of central nervous system embryonal tumor, not otherwise specified

    ObjectiveTo review the clinical records of patients with central nervous system (CNS) embryonal tumors, not otherwise specified (NOS); and summarize their clinical features, diagnosis, and treatment.MethodWe reviewed the data of patients with intracranial tumors admitted to Department of Neurosurgery of West China Hospital, Sichuan University from January 2014 to December 2016, and retrospectively analyzed the clinical features, diagnosis, and treatment of seven patients with CNS embryonal tumors, NOS.ResultsThere were 4 males and 3 females, and the mean age was 25.4 years old. The tumor was located in cerebral hemisphere in 5 patients, and in third ventricle in 2. Clinical presentation included headache, nausea, and vomiting due to intracranial hypertension, and focal neurological signs. All patients underwent craniotomy for tumor resection and postoperative pathology confirmed CNS embryonal tumor, NOS. The patients were followed up for 6 months to 3 years, and 2 patients died during follow-up.ConclusionsCNS embryonal tumor, NOS is malignant intracranial lesion, and has been enlisted as a separate entity under classification of CNS embryonal tumors. It has its unique radiological features, including rare occurrence of perilesional edema, cystic changes, and clear demarcation. Through comprehensive treatment including surgical resection, chemotherapy, and radiation therapy, patients can enjoy prolonged survival and improved quality of life.

  • 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。

  • Analysis of Hypothalamic Reactions Shortly after the Resection of the Third Ventricle Tumor via Transcallosal-interforniceal Approach

    目的 探讨经胼胝体-穹窿间入路切除第三脑室肿瘤术后,近期下丘脑反应的发生情况及相关因素,为防治第三脑室肿瘤术后下丘脑反应提供参考。 方法 回顾分析2003年1月-2008年12月经胼胝体-穹窿间入路切除的78例第三脑室肿瘤患者手术后近期(1个月内)下丘脑反应的发生情况,并将其按照肿瘤部位、病理性质、大小、血供、手术切除程度进行分类统计,用SPSS 13.0软件logistic 回归分析影响这些并发症的因素。 结果 78例术后下丘脑反应37例,发生率47.4%;死亡5例,下丘脑反应病死率为13.5%(5/37)。其中电解质糖代谢紊乱33例(42.3%),尿崩症27例(34.6%),激素水平低下16例(20.5%),高热6例(7.7%)。好转痊愈率:激素水平低下43.7%,其余均>70%。第三脑室前部颅咽管瘤术后最容易发生下丘脑反应(P<0.05)。 结论 经胼胝体-穹窿间入路切除第三脑室肿瘤术后近期存在程度不同的下丘脑反应,其发生与肿瘤部位、病理性质有密切关系。经积极治疗,大部分下丘脑反应能在术后1个月内好转甚至痊愈。

  • Study on the correlation between PIK3CA/TP53 gene mutations and molecular typing andhistological grading of breast cancer

    ObjectiveTo provide reference for further treatment by analyzing the relationship between mutant genes of breast cancer and histological classification and molecular typing of breast cancer.MethodsRetrospectively collectted the pathological specimens of 46 breast cancer patients who treated by the Dongguan Maternal and Child Health Hospital and the Dongguan Houjie Hospital between February 2016 and August 2017 without chemotherapy. Among the selected 46 breast cancer patients, we detected tumor tissue estrogen receptor (ER)/ pregnancy hormone receptor (PR)/human epidermal growth factor receptor-2 (HER-2) status by immunohistochemistry and classified the pathological tissue section. By using multiple PCR techniques, we detected 207 hot mutation regions of the 50 extended tumor-related genes on the semiconductor sequencing platform.ResultsThere were 8 cases of grade Ⅰ, 18 cases of grade Ⅱ, 20 cases of grade Ⅲ in 46 breast cancer patients according to histological grade. Of the 46 cases, there were 23 cases of Luminal B, 9 cases of Luminal A, 9 cases of HER-2 (+), 5 cases of type besal-like according to ER/PR/HER-2 expression status. Moreover, we found that there were 33 gene locus mutations of 8 genes, including AKT1, APC, BRAF, CDKN2A, KRAS, PTEN, PIK3CA, and TP53. Among of them, the mutation of PIK3CA gene took the most of 24 cases, followed by TP53 (18 cases), 2 cases of CDKN2A gene mutation, and 1 case in the remaining four types of genes respectively. we found that the gene mutations of breast cancer were not related to the histological classification and molecular type (P>0.05), the PIK3CA gene mutation was related to the histological classification of breast cancer, the lower the histological classification level, the higher PIK3CA gene mutation rate (P<0.05). TP53 gene mutation was not related to histological grading and molecular type (P>0.05).Conclusions The PIK3CA gene mutation rate in patients with histological grading Ⅰ level increased significantly. The combination of PIK3CA gene mutation and histological grading of breast cancer may become a molecular biological indicator to judge the degree of malignancy and prognosis of breast cancer.
