目的研究脊髓胶质瘤术后放疗的疗效以及影响预后的因素.方法回顾性分析本科原发性脊髓胶质瘤术后放疗29例,统计患者治疗的有效率、生存率以及各因素对生存率的影响.结果患者的近期有效率、5年生存率及无瘤生存率分别为82.1%、60.7%和57.1%;Cox模型多因素分析得出病理分级与预后显著相关,低分级的室管膜瘤和星形细胞瘤预后明显好于间变性室管膜瘤和恶性星形细胞瘤,胶质母细胞瘤的预后最差;放射剂量≥52 Gy的患者预后好于剂量<52 Gy的;而年龄、性别、部位、手术和放疗的间隔时间、手术方式均与预后无关.结论手术无法切除的脊髓胶质瘤患者经术后放射治疗能缓解症状并达到满意的疗效,病理分级与放疗剂量是影响患者预后的重要因素. 相似文献

目的:探讨脊髓室管膜瘤术后放疗疗效及预后影响因素。方法:回顾性分析2009年1月至2018年12月首都医科大学附属北京世纪坛医院放疗科收治的经病理证实的32例脊髓室管膜瘤术后放射治疗患者的临床资料,观察疗效并进行预后影响因素分析。生存分析采用Kaplan-Meier法,单因素分析采用Log-Rank法,多因素分析采用Cox比例风险回归模型评估。结果:中位随访61.5月,11例发生术后复发,复发时间在1~80月,平均39.4月,9例为原位复发,2例发生全中枢播散。随访中,患者死亡3例,均为肿瘤相关死亡。3年、5年无进展生存(PFS)率分别为 68.8%(22/32)、65.6%(21/32),3年、5年总生存(OS)率分别为93.8%(30/32)、90.6%(29/32)。手术切除程度、病理级别、放疗对无进展生存率具有显著性影响(P=0.012、P=0.004、P=0.000),全切除术组患者的总生存率明显优于次全切除术组,两组差异具有统计学意义(P=0.001)。性别、年龄、术后化疗既不影响无进展生存率,也不影响总生存率。Cox比例风险回归模型进行多因素预后分析,结果显示术后放疗影响脊髓室管膜瘤患者的无进展生存率,差异具有统计学意义(HR=0.061,95%CI:0.016~0.237,P=0.000)。结论:手术是室管膜瘤的首选治疗方法。部分切除和间变性室管膜瘤患者,术后放疗是重要的辅助治疗手段;手术切除程度、病理级别和放疗影响室管膜瘤患者预后。 相似文献

BACKGROUND: Because few large studies of pediatric ependymoma treatment are available, the authors believed that a retrospective review of treatment outcomes from a single institution would yield potentially valuable information regarding potential prognostic factors. In this article, they report their 20-year institutional experience with this disease. METHODS: Medical records were reviews of patients with intracranial ependymoma who received their initial treatment at the Children's Hospital of Philadelphia (CHOP)/Hospital of the University of Pennsylvania (HUP) between January 1980 and December 2000. Of the 61 patients who were identified, 49 patients underwent primary therapy at CHOP/HUP and formed the basis for the study. Actuarial overall survival (OS) and progression-free survival (PFS) were determined by the Kaplan-Meier method. Univariate and multivariate analyses were performed using the log-rank test and Cox proportional-hazards models. RESULTS: With median follow-up of 110.2 months, the 5-year OS and PFS rates were 66.2% and 40.7%, respectively. Older age and higher radiation dose significantly predicted for improved OS. Anaplastic histology predicted for decreased PFS. Cervical spinal cord extension resulted in decreased OS primarily caused by failures outside the primary site. Patients who had a favorable prognosis (aged >/=3 years, no dissemination or cord extension, complete resection, and radiation dose >/=54 grays [Gy]) had 5-year OS and PFS rates of 83.1% and 60.6%, respectively. CONCLUSIONS: In this study of patients with pediatric intracranial ependymoma, OS and PFS rates were concordant with the rates published in other modern series. The finding of a dose response up to 54 Gy supported the current trend toward dose escalation. Tumor extension to the cervical spine was identified as a predictor for failure outside of the primary site. Although the survival rates were encouraging, there is still significant room for improvement in the management of this disease. 相似文献

目的 进一步分析Ⅳ期NSCLC化疗同期三维放疗的预后因素。方法 对2003—2010年前瞻性入组201例Ⅳ期NSCLC患者重新进行预后评价,包括依据放疗剂量>36 Gy的159例OS的影响因素分析,以及120例PFS的影响因素分析。化疗以铂类为基础的两药联合方案,中位周期数4个。原发肿瘤中位放疗剂量63 Gy。Kaplan-Meier法计算生存率并Logrank检验,Cox模型预后多因素分析时间从最长的3年延长至5年。结果 全组201例1、2、3、5年OS及中位生存期分别为40.1%、17.3%、10.2%、5.1%及10个月。近期疗效中CR、PR、SD、PD分别为7.5%、66.0%、19.5%、6.9%,其中位生存期分别为19、13、8、6个月(P=0.000)。化疗4~5周期同期≥63 Gy与<63 Gy患者1、2、3、5年PFS和中位生存期分别为77.4%、36.2%、27.2%、15.9%和20个月与32.6%、21.7%、0%、0%和9个月(P=0.002)。4~5周期化疗、疗后KPS稳定或增加、GTV<175 cm3为OS影响因素(P=0.035、0.000、0.008)。原发肿瘤三维放疗≥63 Gy对PFS的影响接近有统计学意义(P=0.051)。结论 Ⅳ期NSCLC 4~5个周期化疗同期三维放疗≥63 Gy三维放疗使PFS、OS明显延长。 相似文献

Background
Ependymoma is the most common glial tumor of the adult spinal cord. Current consensus recommends surgical resection with gross total resection (GTR) whenever possible. We performed a comprehensive review of the literature to evaluate whether adjuvant radiotherapy after subtotal resection (STR) has any benefit.Methods
A PubMed search was performed to identify adult patients with spinal cord ependymoma who underwent surgical resection. Only patients who had clearly defined extent of resection with or without adjuvant radiotherapy were included for analysis. Kaplan-Meier and multivariate Cox regression survival analyses were performed to determine the effects of adjuvant radiotherapy on progression-free survival (PFS) and overall survival (OS).Results
A total of 348 patients underwent surgical resection of spinal cord ependymomas, where GTR was obtained in 77.0% (268/348) of patients. Among those who received STR, 58.8% (47/80) received adjuvant radiotherapy. PFS was significantly prolonged among those who received adjuvant radiotherapy after STR (log rank; P < .001). This prolonged PFS with adjuvant radiotherapy remained significant in multivariate Cox regression analysis (STR versus STR + RT group; hazard ratio (HR) = 2.26, P = .047). By contrast, improved OS was only associated with GTR (GTR versus STR + RT group; HR = 0.07, P = .001) and benign ependymomas (HR = 0.16, P = .001).Conclusions
Surgery remains the mainstay treatment for spinal cord ependymomas, where GTR provides optimal outcomes with longest PFS and OS. Adjuvant radiotherapy prolongs PFS after STR significantly, and OS is improved by GTR and benign tumor grade only. 相似文献17.
