D-二聚体水平在初诊弥漫大B细胞淋巴瘤患者预后评估中的价值

目的探讨D-二聚体水平在弥漫大B细胞淋巴瘤(DLBCL)患者中的预后意义。方法回顾性分析2015年1月至2019年6月天津市人民医院收治的70例初诊DLBCL患者的临床资料,根据受试者工作特征(ROC)曲线确定D-二聚体判断患者生存的最佳截断值,并将患者分组。比较不同D-二聚体水平患者间凝血相关指标及临床病理特征差异;采用Kaplan-Meier法对总生存(OS)进行单因素分析,采用Cox回归模型进行OS多因素分析。结果根据ROC曲线,D-二聚体判断患者生存的最佳截断值为0.75 mg/L。D-二聚体≥0.75 mg/L组(36例)和<0.75 mg/L组(34例)中不同临床分期、国际预后指数评分、乳酸脱氢酶水平的患者比例比较,差异均有统计学意义(均P<0.05);血浆凝血酶原时间分别为(13.5±0.9)s和(13.0±0.8)s,活化部分凝血活酶时间分别为(37±5)s和(34±6)s,差异均有统计学意义(均P<0.05)。单因素生存分析显示,Ann Arbor分期Ⅲ~Ⅳ期、国际预后指数评分>2分、乳酸脱氢酶水平>240 U/L、有B症状、D-二聚体水平≥0.75 mg/L DLBCL患者5年OS率均降低(均P<0.05)。多因素Cox回归分析显示,D-二聚体≥0.75 mg/L为DLBCL患者OS独立危险因素(HR=0.368,95%CI 0.144~0.944,P=0.038)。结论D-二聚体水平可作为判断DLBCL患者预后的临床指标,D-二聚体水平高患者预后不良。

MYC protein expression is associated with poor prognosis in diffuse large B cell lymphoma patients treated with RCHOP chemotherapy

This study aims to investigate the prognostic significance of the MYC protein expression in diffuse large B cell lymphoma (DLBCL) patients treated with RCHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone). A total of 60 patients with DLBCL from 2008 to 2013 were included. Formalin-fixed, paraffin-embedded DLBCL samples were analyzed for MYC protein expression and divided into high or low MYC group. The MYC protein expression and the international prognostic variables were evaluated. The high MYC protein expression predicted a shorter 3-year estimated overall survival (OS) and progression-free survival (PFS) versus the low MYC protein expression (57 % vs. 96 %, P?<?0.001 and 50 % vs. 96 %, P?=?0.001, respectively). Multivariate analysis confirmed the prognostic significance of the MYC protein expression for both OS (HR, 11.862; 95 % CI, 1.462–96.218; P?=?0.021) and PFS (HR, 6.073; 95 % CI, 1.082–34.085; P?=?0.040). MYC protein expression with International Prognostic Index (IPI) score distinguished patients into three risk groups with different 3-year OS rates (χ ² 23.079; P?<?0.001) and distinct 3-year PFS rates (χ ² 15.862; P?<?0.001). This study suggests that the MYC protein expression is an important inferior prognostic factor for survival in patients with DLBCL treated with RCHOP. The combinative model with IPI score and MYC protein expression could stratify DLBCL patients into prognostically relevant subgroups more effectively than either the IPI or the MYC alone.     

弥漫大B细胞淋巴瘤的一线治疗

 短疗程化疗联合受累野局部放疗(IFRT)是治疗局限期(Ⅰ～Ⅱ期) 弥漫大B细胞淋巴瘤患者的重要方法,但对于放疗的价值,目前存在争议。含蒽环类药物的联合化疗虽然使部分患者有可能被治愈,但依然有患者面临死亡。于是,研究者努力尝试通过提高化疗剂量密度或强度来提高患者的生存,但对老年患者,则试图减少剂量或使用毒性低的药物来进一步提高患者的生存。另外放射免疫疗法、生物靶向治疗等多方面的研究也取得了一定进展。     

Emerging prognostic factors in diffuse large B cell lymphoma

PURPOSE OF REVIEW: Diffuse large B cell lymphoma (DLBCL) is the most common lymphoma subtype, characterized by marked clinical and biologic heterogeneity. Gene expression studies together with new monoclonal antibody production are playing an increasing role in determining important prognostic factors/biomarkers predictive of outcome. Despite these technical advances, much confusion exists in the literature as to what constitutes the important biomarkers for determining patient outcome. The purpose of this review is to highlight recent advances in our understanding of novel biomarkers in DLBCL and how these might be incorporated into current risk-adjustment models for prognosis. RECENT FINDINGS: Microarray gene expression analyses have revolutionized our approach to biomarkers in non-Hodgkin lymphomas. Thousands of genes can now be simultaneously analyzed for individual patients, creating a wealth of new data. This has resulted in an improved understanding of the basic biology, as well as the development of new outcome predictors. Monoclonal antibody reagents for some of these biomarkers already exist, allowing for their rapid validation at the level of protein expression and potential clinical translation. SUMMARY: A molecular classification of DLBCL is a current reality, and together with routine morphology, immunophenotype, and molecular cytogenetics, has allowed us to more accurately subclassify DLBCL and determine clinically relevant subgroups. The time is right to begin to consider how these novel biomarkers should be incorporated into current prognostic models to move beyond the clinically based International Prognostic Index     

PIM1表达与弥漫大B细胞淋巴瘤患者预后的关系

背景与目的:Pim1是一种原癌基因,具有抑制肿瘤细胞凋亡、促进肿瘤细胞增殖的功能.本研究旨在探讨PIM1蛋白与原发性弥漫大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)预后的关系.方法:采用免疫组化方法评估53例初治原发性DLBCL患者的PIM1表达,回顾性分析PIM1的表达与化疗反应性和总生存的关系.结果:PIM1蛋白高表达与DLBCL的负性预后相关,且它的表达与非生发中心的表型相关(r=0.404,P=0.003).PIM1蛋白高表达患者的3年总生存率和化疗完全缓解率均比低表达者低,差异有统计学意义(29.2%vs62.1%:29.2%vs 68.9%,P＜0.001和P=0.006).PIM1和国际预后指数(international prognostic index,IPI)的多因素分析表明,PIM1是总生存独立的预后因素(P=0.013).单因素Logistic回归分析表明,PIM1的表达与化疗的完全缓解率呈负相关.结论:在DLBCL患者中,PIM1的高表达可以作为一个临床预后不良标志.

弥漫大B细胞淋巴瘤的分子靶向治疗

 弥漫大B细胞淋巴瘤（DLBCL）是最常见的成人非霍奇金淋巴瘤。现阶段利妥昔单抗与CHOP方案的联合应用已显著改善了DLBCL的预后,约50%的DLBCL可以治愈。然而由于肿瘤的异质性,对于难治、复发的DLBCL仍然缺乏行之有效的治疗方法。随着基因表达谱(GEP)的运用以及对淋巴瘤细胞内活化信号途径的深入研究,发现了很多潜在的治疗靶点。     

Serum C-reactive protein as an important prognostic variable in patients with diffuse large B cell lymphoma

C-reactive protein (CRP) is an acute-phase reactant that is a promising biomarker in patients with cancer of many kinds. The aim of this retrospective study was to evaluate significant changes in CRP levels as a parameter for the response effect and long-term survival of patients with diffuse large B cell lymphoma (DLBCL). Serum CRP data were collected in 94 patients with DLBCL from October 2006 to August 2009 in Cancer Center, Sun Yat-Sen University. Results were correlated with clinical data. The median CRP serum level in patients with DLBCL was 30.91 ± 53.35 in male and 22.39 ± 29.89 mg/L in female. Base line CRP levels were correlated with International Prognostic Index (IPI) scores (p = 0.03). Among the patients with an IPI score of 1-2, base line CRP levels were correlated with long-term survival (p = 0.001). Base line CRP levels were also correlated with OS (p = 0.001) and varied with different clinical stages (p = 0.03). The corresponding CRP levels in the patients with 2 cycles of chemotherapy were correlated with short-term treatment response (p = 0.003) and OS (p = 0.04) or TTP (p = 0.03). CRP serum levels can be used as additional prognostic parameter in patients with diffuse large B cell type lymphoma.
