目的综合评价美罗华联合化疗对非霍奇金淋巴瘤的疗效。方法应用国际Cochrance协作网的系统评价方法,对关于非霍奇金淋巴瘤接受美罗华联合化疗组与单纯化疗组疗效比较的随机和半随机试验研究的结果进行系统评价。结果共检索到6个试验包括1132例患者,美罗华联合化疗组的完全缓解率高于单纯化疗组(OR=4.15,95%CI2.36~7.30,P<0.00001),经异质性检验显示6个试验存在异质性(χ2=15.15,P=0.010)。采用随机效应模型进行综合分析。敏感性分析亦证实美罗华联合化疗的疗效优于单纯化疗组(OR=5.14,95%CI3.38~7.81,P<0.00001)。结论美罗华联合化疗对非霍奇金淋巴瘤有一定疗效,有必要开展更多设计良好的临床随机对照试验,进一步证明其临床效果。  相似文献

目的研究凋亡抑制蛋白Bcl-2在弥漫大B细胞淋巴瘤中的表达和临床意义。方法采用免疫组织化学法对84例DLBCL石蜡标本进行Bcl-2检测,另取20例淋巴结反应性增生(RH)作为对照组。结果 Bcl-2在DLBCL中的表达率58.3%(49/84)明显高于淋巴结反应性增生40%(8/20),两者差异没有统计学意义(P>0.05);Bcl-2在DLBCL中的表达与患者年龄、性别无关(P>0.05),但与首发部位、临床分期、IPI分级、血清LDH水平、结外病灶数目有关(P<0.05)。结论 Bcl-2参与DLBCL的发生发展,可能是判断预后极有价值的指标。  相似文献

目的 评价国内美罗华联合CHOP方案化疗对非霍奇金淋巴瘤的疗效.方法 应用国际Cochrane协作网的系统评价方法,经计算机检索,纳入美罗华联合CHOP方案治疗B细胞性非霍奇金淋巴瘤的随机对照试验.评价纳入研究的质量,并进行资料提取后,采用Rev Man 4.2软件进行Meta分析.结果 共纳入7篇文献,包括357例患者,文献间具有同质性,采用固定效应模型,结果:OR=3.02,95%CI(1.94,4.72).美罗华联合CHOP方案治疗组与单纯CHOP方案对照组的完全缓解率比较,差异有统计学意义(P<0.01).结论 目前国内美罗华联合CHOP方案化疗对非霍奇金淋巴瘤有一定疗效,但由于纳入研究样本量小且质量较低,上述结论尚需要高质量、大样本的随机双盲对照试验加以证实.  相似文献

目的探讨胃淋巴瘤两种主要类型:弥漫性大B细胞淋巴瘤(Diffuse large B—ceil lymphoma,DLBCL)和黏膜相关淋巴组织淋巴瘤(Mucosa-gssociated lymphoid tissue Iymphoma,MALToma)CT征象的异同,为胃淋巴瘤的生物学行为评价和影像学鉴别诊断提供依据。方法回顾分析我院规范CT检查胃淋巴瘤病例42例,均经胃镜或手术病理证实。根据病理结果将全部病例分为DLBCL和MALToma。分析两种类型淋巴瘤CT影像学征象特征,包括病变所处胃的分部、范围、形态、厚度、强化、黏膜及浆膜面情况、淋巴结转移、腹腔大血管及脏器侵犯情况、腹腔转移及有无腹水等。统计学分析比较两种类型淋巴瘤的CT征象差异。结果DLBCL多累及胃的多个部分,且以近端胃受累为主,MALToma以胃的单一部分受累更为多见,且以胃远端分布为主,差异有显著性。DLBCL癌肿平均厚度(275±152)cm,大于MALToma癌肿平均厚度(123±064)cm,差异存在显著性(P〈0.01)。DLBCL胃壁以弥漫性、不均匀增厚为主,MALToma以局限性、均匀增厚为主;DLBCL较MALToma更易侵犯浆膜,淋巴结转移率较MALToma高,转移淋巴结体积大、分布更为广泛,侵犯腹腔干分支大血管及腹腔脏器的比例均高于MALToma。DLBCL静脉期强化0T值(6909±1349)HU.低于MALToma静脉期强化CT值(81.79±25.82)Hu。MALToma黏膜面“白线征”显示率高于DLBCL;DLBCL浆膜侧“血管穿行征”显示率高于MALToma。结论GT影像学征象可反映DLBCL和MALToma的生物学行为,显示两种胃淋巴瘤侵袭性的差异,可作为两者鉴别的重要手段。MALToma黏膜面“白线征”、DLBCL浆膜侧“血管穿行征”丰富了胃淋巴瘤的CT征象,为鉴别诊断及生物学行为评价提供了新的指标。  相似文献

目的 分析比较弥漫大B细胞淋巴瘤 (DLBCL)的总体及不同治疗方案疗效,探讨影响治疗方案疗效的因素。 方法 回顾性分析2000年1月至2010年12月在四川大学华西医院诊治的489例初治DLBCL患者临床资料。依据其所接受化疗方案有无利妥昔单抗的不同,分为RCHOP (利妥昔单抗+环磷酰胺,阿霉素/表阿霉素,长春新碱,泼尼松/地塞米松)样组(n=184)和CHOP (环磷酰胺,阿霉素/表阿霉素,长春新碱,泼尼松/地塞米松)样组(n=299),比较两组患者疗效并分析可能的临床影响因素。 结果 RCHOP样组方案有效率高于CHOP样组方案 (84.3% vs.75.6%,P=0.015)。多因素分析显示,脾大、淋巴细胞绝对值(ALC)降低、国际预后指数(IPI) 3~5分及CHOP方案是影响总体疗效的不良因素,ALC降低 〔优势比(OR)=2.060,95%CI:1.159~3.661,P=0.014〕和IPI3~5分 (OR=2.157,95%CI:1.170~3.978,P=0.014)是影响CHOP样组疗效的危险因素,而血红蛋白(HGB)降低 (OR=3.010,95%CI:1.238~7.314,P=0.015)和IPI3~5分 (OR=2.872,95%CI:1.193~6.914,P=0.019)是影响RCHOP样组疗效的危险因素;ALC在0.8×10 9/L~1.0×10 9/L时,RCHOP样组方案有效率高于CHOP样组;Bcl-2+/-、GCB/non-GCB在不同治疗方案间疗效无差异。 结论 RCHOP样组方案疗效优于CHOP样组及二线治疗方案; ALC降低、HGB降低分别是影响CHOP样组及RCHOP样组疗效的独立危险因素。  相似文献

目的系统评价中国非霍奇金淋巴瘤患者接受利妥昔单抗联合CHOP方案化疗的疗效与安全性。方法以"美罗华"、"利妥昔单抗"、"非霍奇金淋巴瘤"、"系统评价"、"meta分析"、"随机对照试验"为检索词,计算机检索中国期刊网全文数据库(1991-2010年)、中国生物医学文献数据库(1991-2010年)、维普数据库(1991-2010年)、万方数据库(1991-2010年),手工检索可纳入文献的参考文献及可以利用的综述,收集国内关于利妥昔单抗联合CHOP方案治疗非霍奇金淋巴瘤的随机对照临床试验,两名评价者独立依据纳入标准筛选文献,对纳入文献行方法学质量评价后提取数据,统计学分析采用RevMan4.2软件进行。结果共纳入4个随机对照试验,包括218例患者。Meta分析结果显示,利妥昔单抗联合CHOP方案化疗与单用CHOP方案比较,其完全缓解率(相对危险度1.32,95%可信区间1.01~1.73)和总有效率(相对危险度1.22,95%可信区间1.04~1.44)差异有统计学意义,主要的化疗相关不良反应(白细胞下降、血小板下降、恶心呕吐、肝损害)的发生率差异无统计学意义。结论国内目前有限的证据表明,与单用CHOP方案相比,联合应用利妥昔单抗能提高中国非霍奇金淋巴瘤患者的完全缓解率和总有效率,同时并不增加治疗的不良反应。但由于纳入的研究样本量较小,随机试验的总体质量不高,以上结论尚有待于更多大样本、设计完善、实施良好的前瞻性随机双盲对照试验进一步证实。  相似文献

ObjectiveDiffuse large B-cell lymphoma (DLBCL) is often associated with bone marrow infiltration, and 2-deoxy-2-(18F) fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has potential diagnostic significance for bone marrow infiltration in DLBCL.MethodsA total of 102 patients diagnosed with DLBCL between September 2019 and August 2022 were included. Bone marrow biopsy and 18F-FDG PET/CT examinations were performed at the time of initial diagnosis. Kappa tests were used to evaluate the agreement of 18F-FDG PET/CT with the gold standard, and the imaging features of DLBCL bone marrow infiltration on PET/CT were described.ResultsThe total detection rate of bone marrow infiltration was not significantly different between PET/CT and primary bone marrow biopsy (P = 0.302) or between the two bone marrow biopsies (P = 0.826). The sensitivity, specificity, and Youden index of PET/CT for the diagnosis of DLBCL bone marrow infiltration were 0.923 (95% CI, 0.759–0.979), 0.934 (95% CI, 0.855–0.972), and 0.857, respectively.Conclusion18F-FDG PET/CT has a comparable efficiency in the diagnosis of DLBCL bone marrow infiltration. PET/CT-guided bone marrow biopsy can reduce the misdiagnosis of DLBCL bone marrow infiltration.  相似文献

Objective: To evaluate the efficacy and safety of blood-letting therapy (BLT) in treatment of hypertension. Methods: A comprehensive electronic and manual bibliographic searches were performed in Cochrane Central Register of Controlled Trials, Excerpt Medica Database (EMBASE), PubMed, China National Knowledge Infrastructure, Chinese Scientific Journal Database, Chinese Biomedical Literature Database, and Wanfang Database to identify randomized controlled trials (RCTs) in which hypertensive patients were treated with BLT or BLT plus antihypertensive drugs (BPAD) against placebo, no treatment or antihypertensive drugs. The Cochrane Risk Assessment Tool was used to assess the methodological quality of trials. The Review Manager 5.3 software was used for meta-analysis. Results: A total of 7 RCTs with 637 hypertensive patients from 1989 to 2017 were identified. Compared with antihypertensive drugs, blood pressure was significantly reduced by BLT (RR=1.21, 95% CI: 1.01 to 1.44, P=0.03; heterogeneity: P=0.06, I2=60%) and BPAD (RR=1.25, 95% CI, 1.02 to 1.53, P=0.03; heterogeneity: P= 0.01, I2=71%). Moreover, a significant improvement in Chinese medicine syndrome by BLT (RR=1.32; 95% CI: 1.14 to 1.53, P=0.0002; heterogeneity: P=0.53, I2=0%) and BPAD (RR=1.47; 95% CI: 1.06 to 2.04, P=0.02; heterogeneity: P=0.13, I2=56%) was identified. The reported adverse effects were well tolerated. Conclusions: Although some positive findings were identified, no definite conclusions regarding the efficacy and safety of BLT as complementary and alternative approach for treatment of hypertension could be drew due to the generally poor methodological design, significant heterogeneity, and insufficient clinical data. Further rigorously designed trials are warranted to confirm the results.  相似文献

Objective To investigate the efficacy and safety of rituximab (RTX) in the treatment of idiopathic membranous nephropathy (IMN) with nephrotic syndrome with a systematic review and meta-analysis. Methods PubMed, Embase, Cochrane Library and Clinical Trials (December 2016) were searched to identify researches investigating the treatment of RTX in adult patients with biopsy-proven IMN. Complete remission (CR) or partial remission was regarded as effective therapy, and the cumulated remission rate was calculated. Results Seven studies involved 120 patients (73% were men) were included in our systematic review and meta-analysis. All were prospective observation cohort studies or matched-cohort studies, mainly came from two medical centers, and one study was multi-centric (four nephrology units in northern Italy). The creatinine clearance was more than 20 ml/(min·1.73 m2) and persistent proteinuria higher than 3.5 g/d for at least 6 months. All patients received treatment previously[44(36.7%)had immunosuppressive treatment].In 12-and 24-month,56%(95% CI,0.47-0.65) and 68%(95%CI,0.41-0.87)patients could reach remission,while 15%(95%CI,0.09-0.23)and 20%(95%CI,0.12-0.32) patients could reach CR. The reduction in proteinuria was gradual and obvious, paralleled with upward trend of serum albumin level and decreasing serum cholesterol level. Renal functions were stable. Relapses happened in 24 months were around 8%. RTX related adverse events were mild and were mostly infusion-related reactions. Conclusions RTX treatment in IMN was efficient, well tolerated and safe. More than 60% patients can reach partial remission or CR in 24 months, and relapse is rare. Adverse events of RTX are mostly infusion-related reactions and generally mild.  相似文献
