讨论 原发于睾丸的NHL属于结外NHL,临床上较为少见,睾丸NHL合并自身免疫性溶血性贫血更为少见,本例患者发生溶血与NHL免疫功能调节异常、B淋巴细胞产生异常抗体有关,患者异常的抗红细胞抗体在红细胞表面的过度表达导致红细胞破坏加速发生溶血,经激素、手术摘除睾丸、联合化疗,去除了原发病,近期临床疗效良好,未见溶血再发,但远期的疗效及预后有待于今后随访结果来证实。 相似文献

Epstein-Barr virus associated diffuse large B-cell lymphoma complicated by autoimmune hemolytic anemia and pure red cell aplasia. 总被引:2,自引:0,他引:2

A 53-year old man with systemic lymphadenopathy and hepatosplenomegaly was diagnosed with diffuse large B cell-lymphoma after inguinal lymph node biopsy. Anemia was noted, direct and indirect Coombs tests were positive, and the haptoglobin level was low. However, the bone marrow aspirate revealed erythroid aplasia. Co-existing autoimmune haemolytic anemia (AIHA) and pure red cell aplasia (PRCA) were diagnosed. In situ hybridization with Epstein-Barr virus (EBV) encoded small RNA (EBER) showed positive findings in lymphoma cells. Southern blot hybridization revealed immunoglobulin heavy chain gene rearrangement and a clonal EBV terminal repeat, indicating monoclonal proliferation of EBV in infected B cells. The patient was treated with CHOP, resulting in a complete remission (CR). AIHA and PRCA subsided after 3 courses of chemotherapy. In conclusion, this case demonstrates not only the association of B-cell lymphoma with autoimmune disorders but also the involvement of EBV in these conditions. 相似文献

Non-Hodgkin's lymphoma (NHL) refers to a heterogeneous group of lymphoproliferative diseases with a diversity of clinical courses, including involvement in another organs. NHL frequently involves the thoracic structures, and particularly the mediastinum and lung parenchyma. Several clinical reports have described bronchial-associated lymphoid tissue (BALT) lymphoma as an endobronchial lesion, but endobronchial infiltration with diffuse large B-cell lymphoma is extremely rare. Here, we provide the first report of this condition confirmed by a histopathological study and the presence of an immunoglobulin heavy chain (IgH) gene rearrangement detected by a polymerase chain reaction (PCR). 相似文献

目的:探讨EB病毒阳性患者的胃弥漫大B 细胞淋巴瘤(diffuse large B-celllymphoma,DLBCL )病理学特点及预后。方法:回顾性分析北京大学基础医学院病理学系2009年1 月至2015年1 月75例胃弥漫大B 细胞淋巴瘤患者的临床资料,15例EB病毒(Epstein-Barr virus,EBV )阳性者为病例组,60例EBV 阴性者为对照组,采用免疫组织化学法和EB病毒RNA 探针原位杂交法检测Bcl- 2、c-myc 蛋白表达及EBV-EBER 情况,分析EBV 阳性的胃DLBCL 患者的病理学特点及预后。结果:EBV 阳性组在临床表现、年龄、性别、起源、细胞形态等方面与EBV 阴性组相比,差异无统计学意义(P > 0.05);在Bcl- 2、c-myc 蛋白表达方面,EBV 阳性组与EBV 阴性组相比,差异无统计学意义(P > 0.05);R-CHOP 方案治疗下,EBV 阳性组与EBV 阴性组相比,中位总生存期(median overallsurvival,OS)分别为15.1 个月和31.4 个月,差异具有统计学意义(P = 0.01)。 结论:发生于胃DLBCL 患者中,EB病毒感染对临床表现、瘤细胞的起源、形态、蛋白表达等方面无明显影响;EB病毒阳性的DLBCL 患者并不局限于老年人;R-CHOP 治疗下EB病毒阳性患者的预后比EB病毒阴性的患者预后差。 相似文献

弥漫大B细胞淋巴瘤(DLBCL)是最常见的恶性淋巴瘤.虽然R-CHOP标准治疗方案改善了DLBCL患者的整体生存,但高危患者5年总生存率仍<50%.因此DLBCL一直是研究和关注的热点,如新药的联合治疗、以嵌合抗原受体T细胞(CAR-T)和抗体治疗为代表的免疫靶向治疗、如何降低治疗的长期不良反应以及寻找新的预后生物学标志物和分型系统等.文章就第60届美国血液学会年会上DLBCL的最新进展进行概述. 相似文献

BACKGROUND: Prognosis of lymphoma patients is usually estimated at the time of diagnosis and the estimates are guided by the International Prognostic Index (IPI). However, conditional survival estimates are more informative clinically, as they consider those patients only who have already survived a period of time after treatment. Conditional survival data have not been reported for lymphoma patients. METHODS: Conditional survival was estimated for 1209 patients with diffuse large B-cell lymphoma (DLBCL) from the population-based LYFO registry of the Danish Lymphoma Group. The Kaplan-Meier method was used to estimate conditional survival at 0-5 years after diagnosis. RESULTS: The probability of surviving 5 years increases with each year survived for the first 3 years after diagnosis, after which the increase is minimal. The median survival increases from 38 months for all patients to between 108 and 120 months, conditioned on survival for at least 3-5 years. The prognostic capacity of the IPI and the age-adjusted IPI was high at diagnosis, but the significance gradually declined in the first years after diagnosis. Furthermore, the prognostic impact of the individual clinical variables of the IPI was also significant at diagnosis, but 2 years after diagnosis only age had prognostic impact. Multivariate analysis of patients who survived > or = 3 years identified only age as a prognostic factor. CONCLUSION: For patients with DLBCL who have survived more than 1 year after diagnosis, the conditional survival probability provides more accurate prognostic information than the conventional survival rate estimated from the time of diagnosis. 相似文献

Despite more effective front-line regimens, a substantial portion of patients with diffuse large B-cell lymphoma relapse and
require further therapy. Several trials have established the efficacy of autologous stem cell transplantation for relapsed
diffuse large B-cell lymphomas, but the benefit has been largely restricted to patients with chemosensitive disease and low-risk
features at the time of relapse. In an effort to improve outcomes following an autologous transplant, researchers are exploring
several avenues, including improvement of salvage regimens, addition of radioimmunotherapy to preparative regimens, and application
of posttransplant treatments to eliminate minimal residual disease. Allogeneic stem cell transplantation also appears promising,
but there is much to learn about optimal patient selection and timing. This review outlines the current approach to the management
of relapsed diffuse large B-cell lymphoma, with an emphasis on newer peritransplant therapies. 相似文献

With the implementation of rituximab, tremendous progress has been achieved in the treatment of diffuse large B-cell lymphoma (DLBCL). Nevertheless, the majority of patients with DLBCL are over the age of 65 years and the management of these patients is often suboptimal. Standard chemo-immunotherapy with curative approach should be appropriate for all elderly patients who can tolerate it. Therefore, a careful evaluation of each patient is mandatory prior to treatment allocation. R- CHOP regimen (rituximab, cyclophosphamide doxorubicin, vincristine, prednisolone) remains the standard of care, but special attention has to be paid to rigorous supportive care. Patients not fit enough for R-CHOP are candidates for dose-reduced therapy or other palliative strategies. 相似文献
