目的探讨增强MRI纹理参数鉴别胶质母细胞瘤(GBM)、原发性中枢神经系统淋巴瘤(PCNSLs)及单发转移瘤(sMT)的可行性。方法回顾性分析2016年1月至2018年9月苏北人民医院收治的经手术或穿刺活检病理确诊的30例GBM、20例PCNSLs及21例sMT患者。应用Mazda软件勾画病灶感兴趣区并提取297个纹理参数,应用Fisher系数、分类错误联合平均相关系数提取(POE+ACC)、交互信息(MI)及三者联合FPM提取法筛选出30个特征参数。计算组内相关系数(ICC)评价观察者间测量纹理参数的一致性。比较GBM、PCNSLs和sMT纹理参数差异。将30个纹理参数纳入b11数据包进行原始数据分析(RDA)、主成分分析(PCA)、线性判别分析(LDA)、非线性判别分析(NDA)统计。结果两名观察者测量30个纹理参数的ICC为0.813~0.892,均≥0.75,表现出良好的一致性。30个纹理参数中,仅S(4,4)SumAverg、Teta3在GBM、sMT和PCNSLs这3种肿瘤间的差异无统计学意义(P均>0.05),其余参数在这3种肿瘤间的差异均有统计学意义(P均<0.05或0.01)。b11数据包RDA、PCA、LDA、NDA这4种分析法诊断正确例数分别为41例、40例、67例、62例,诊断准确率分别为57.8%、56.3%、94.4%、87.3%。其中,NDA分析法诊断准确率最高。结论增强MRI能够提取定量纹理参数,有助于鉴别脑胶质母细胞瘤、原发性淋巴瘤及单发转移瘤。 相似文献

以往对于颅内转移瘤比较一致的看法是手术切除局限于有脑内单发转移且一般情况满意的患者。近年来,随着神经外科的发展,这种传统限制有了改变:即使脑内存在多个转移灶,对危及生命的转移灶也应手术切除。 相似文献

Glioblastoma multiforme (GBM) is the most common and fatal intracranial cancer in humans and exhibits intense and aberrant angiogenesis that sustains its malignancy and involves several angiogenic signals. Among them, vascular endothelial growth factor (VEGF) plays a key role and is overexpressed in GBM. Different cells appear to act as triggers of the aberrant angiogenesis, and, among them, platelets act as key participants. In order to provide further insights into the platelet features and angiogenic role in GBM, this study investigated the effects of platelet releasate on GBM-derived endothelial cells (GECs) and the levels of VEGF and endostatin, as pro- and anti-angiogenic components of platelet releasate from GBM patients. We demonstrate for the first time that: 1) platelet releasate exerts powerful pro-angiogenic effect on GECs, suggesting it might exert a role in the aberrant angiogenesis of GBM; 2) ADP and thrombin stimulation leads to significantly higher level of VEGF, but not of endostatin, in the releasate of platelets from GBM patients than those from healthy subjects; and 3) the intraplatelet concentrations of VEGF were significantly elevated in GBM patients as compared to controls. Moreover, we found a direct correlation between platelet-released VEGF and overall survival in our patient cohort. Although preliminary, these findings prompt further investigations to clarify the biologic relevance of platelet VEGF in GBM and prospective studies for screening GBM patients for anti-VEGF therapy and/or to optimize this treatment. 相似文献

AIM: To investigate the prognostic value of metastaticlymph node ratio(MLNR) in extrahepatic cholangiocarcinoma(ECC) patients undergoing radical resection.METHODS: Seventy-eight patients with ECC were enrolled.Associations between various clinicopathologic factors and prognosis were investigated by KaplanMeier analyses.The Cox proportional-hazards model was used for multivariate survival analysis.RESULTS: The overall three- and five-year survival rates were 47.26% and 23.99%, respectively.MLNR of 0, 0-0.2, 0.2-0.5, and 0.5 corresponded to fiveyear survival rates of 28.59%, 21.60%, 18.84%, and 10.03%, respectively.Univariate analysis showed that degree of tumor differentiation, lymph node metastasis, MLNR, tumor-node-metastasis(TNM) stage, and margin status were closely associated with postoperative survival in ECC patients(P 0.05).Multivariate analysis showed that MLNR and TNM stage were independent prognostic factors after pancreaticoduodenectomy(HR = 2.13, 95%CI: 1.45-3.11; P 0.01; and HR = 1.97, 95%CI: 1.17-3.31; P = 0.01, respectively).The median survival time for MLNR 0.5, 0.2-0.5, 0-0.2, and 0 was 15 mo, 24 mo, 23 mo, and 35.5 mo, respectively.There were statistical differences in survival time between patients with different MLNR(χ2 = 15.38; P 0.01).CONCLUSION: MLNR is an independent prognostic factor for ECC patients after radical resection and is useful for predicting postoperative survival. 相似文献

目的:探讨高龄肺癌患者开胸手术心律失常围手术期的预防和处理。方法:对46例70~85岁肺癌手术患者的资料进行回顾性分析。结果:术后心律失常始发时间出现于术后48h内占69.6%,其中窦性心动过速14例,室上性心律失常24例,室性心律失常3例,有5例表现为不同类型心律失常混合发作。全组无手术死亡。结论:高龄肺癌患者心肺功能储备差,开胸术中、术后易出现心律失常。但术前根据患者身体情况给予积极的处理,手术中注意保护心脏神经,消除术后缺氧和低钾血症等诱因是防止发生心律失常的重要措施,控制心室率是治疗的关键。 相似文献

为探讨上消化道肿瘤围手术期避免输血,且不影响手术质量的可行方法,选择上消化道肿瘤切除患者20例,术中均静脉注射止血药物、控制性降压和血液稀释,以减少术中失血控制输血量。结果术中血压较麻醉前明显降低(P<0.01),脉搏及中心静脉压无明显变化(P>0.05);人均失血量(483.7±290.3)ml,占全血容量的11.8%,除2例关腹前Hb<100g/L者输血外,余18例患者均未输血。提示静脉注射止血药物,控制性降压和血液稀释用于上消化道肿瘤手术可明显减少患者术中出血量,避免输血;且不影响手术质量及术后恢复。 相似文献

Summary A 60-year-old woman with gastric cancer had undergone partial gastrectomy in September 1989. Pathological examination revealed a poorly differentiated adenocarcinoma of pT3pN3pM0 (not resected for cure), stage IV. Postoperative adjuvant therapy comprised 1-(tetrahydro-2-furanyl)-5-fluorouracil plus uracil and OK-432. On 11 August 1990, two forefinger-tip-sized tumors were palpated beneath the operation scar. They increase in size, the superior tumor reaching 4×3 cm, the inferior tumor 5×3 cm on 5 September. Then, on 17 September, the inferior tumor was resected but the superior tumor remained; the histological type was poorly differentiated adenocarcinoma. After the operation, from 20 September, she was given 4 mg irsogladine maleate orally every day. On 8 October, there was no increase in the size of the superior tumor. By 29 October, the superior tumor had disappeared and no further tumor appeared thereafter; the patient showed no sign of relapse.Abbreviations FT
