Approximately 7350 new cases of Hodgkin lymphoma (HL) are diagnosed annually in the United States. The Incidence of HL has a bimodal pattern, with the highest incidence seen in young adults and in elderly patients. The disease is composed of 2 distinct entities: the more commonly diagnosed classical HL and the rare nodular lymphocyte-predominant HL. Classical HL includes the subgroups nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte rich. Selection of the appropriate therapy Is based on accurately assessing the stage of disease. Patients with early-stage disease are treated with combined modality strategies using abbreviated courses of combination chemotherapy followed by Involved-field radiation therapy, whereas those with advanced-stage disease receive a longer course of chemotherapy without radiation therapy. Currently, more than 80% of all patients with newly diagnosed HL are expected to be long-term survivors. Although many patients respond well to initial therapies and have durable long-term remissions, a subset of patients has resistant disease and experiences relapse even after subsequent high-dose chemotherapy and autologous stem cell transplantation. New therapies are clearly needed for these patients. 相似文献

Approximately 8,200 new cases of Hodgkin lymphoma are diagnosed annually in the United States. Common presenting features include painless lymphadenopathy (usually above the diaphragm), cough, fever, night sweats, and weight loss. To decrease late complications, treatment has gradually evolved toward shorter-duration chemotherapy with use of lower-dose, shorter-duration radiation therapy. ABVD (a chemotherapy regimen consisting of doxorubicin, bleomycin, vinblastine, and dacarbazine) is now more commonly used than MOPP (a regimen consisting of mechlorethamine, vincristine, procarbazine, and prednisone) in patients with Hodgkin lymphoma. Many significant complications of therapy (e.g., cardiovascular conditions, infertility, premature menopause, secondary neoplasms) directly reflect the choice of primary treatment and may be reduced by more current treatment strategies. Recurrences of Hodgkin lymphoma are most common in the first few years after diagnosis and treatment. Prognosis is related to the stage of lymphoma, disease bulk, and age of the patient. Currently, more than 80 percent of patients with newly diagnosed Hodgkin lymphoma are expected to be long-term survivors. 相似文献

Previous studies have demonstrated an increase in T-regulatory cells in the involved lymph nodes and peripheral blood of patients with Hodgkin lymphoma. Our study examined whether the detection of T-regulatory cells by flow cytometry could distinguish classical Hodgkin lymphoma (CHL) from benign cases and B-cell non-Hodgkin lymphomas (B-NHL). We measured CD4, CD25, and CD152 in 14 CHLs, 2 nodular lymphocyte-predominant Hodgkin lymphomas, 31 B-NHLs, and 54 benign cases. All T-regulatory cell parameters, including percent lymphocytes CD4+/CD152+ and CD4+/CD25+/CD152+, and mean and median CD152 expression in CD4+/CD25+ lymphocytes, were higher in CHL than in B-NHL and benign. Mean CD152 in CD4+/CD25+ lymphocytes distinguished CHL from benign with 79% sensitivity and 100% specificity, and from B-NHL with 71% sensitivity and 90% specificity. Overall, our results show that T-regulatory cells are increased in CHL and their detection may be a useful tool in differentiating CHL from other entities. 相似文献

Using current diagnostic criteria, primary mediastinal B cell lymphoma (PMBL) cannot be distinguished from other types of diffuse large B cell lymphoma (DLBCL) reliably. We used gene expression profiling to develop a more precise molecular diagnosis of PMBL. PMBL patients were considerably younger than other DLBCL patients, and their lymphomas frequently involved other thoracic structures but not extrathoracic sites typical of other DLBCLs. PMBL patients had a relatively favorable clinical outcome, with a 5-yr survival rate of 64% compared with 46% for other DLBCL patients. Gene expression profiling strongly supported a relationship between PMBL and Hodgkin lymphoma: over one third of the genes that were more highly expressed in PMBL than in other DLBCLs were also characteristically expressed in Hodgkin lymphoma cells. PDL2, which encodes a regulator of T cell activation, was the gene that best discriminated PMBL from other DLBCLs and was also highly expressed in Hodgkin lymphoma cells. The genomic loci for PDL2 and several neighboring genes were amplified in over half of the PMBLs and in Hodgkin lymphoma cell lines. The molecular diagnosis of PMBL should significantly aid in the development of therapies tailored to this clinically and pathogenetically distinctive subgroup of DLBCL. 相似文献

OBJECTIVE: To evaluate the overall risk of breast cancer and breast cancer characteristics in women given supradiaphragmatic radiation therapy for Hodgkin lymphoma. PATIENTS AND METHODS: Medical records of 653 female patients who received supradiaphragmatic radiation therapy for Hodgkin lymphoma at the Mayo Clinic in Rochester, Minn, between 1950 and 1993 were abstracted, and follow-up questionnaires were mailed. In 4 patients, breast cancer was diagnosed before Hodgkin lymphoma was discovered. RESULTS: The median age of 649 patients at supradiaphragmatic radiation therapy was 31.8 years (range, 2.6-86.5 years). The median duration of follow-up was 8.7 years (range, < 1-47.9 years). In 30 patients, breast cancer developed (bilaterally in 4 patients) after supradiaphragmatic radiation therapy; the median interval was 19.9 years (range, 0.7-423 years). The median age at breast cancer diagnosis was 44.4 years (range, 27.5-70.8 years). The standardized morbidity ratio for breast cancer after supradiaphragmatic radiation therapy was 2.9 (95 % confidence interval [CI], 2.0-4.2) (P < .001). Breast cancer risk significantly increased 15 to 30 years after patients received supradiaphragmatic radiation therapy, and risk was inversely related to age at supradiaphragmatic radiation therapy until age 30 years. The standardized morbidity ratio for patients younger than 30 years at supradiaphragmatic radiation was 8.5 (95% CI, 53-13.1) vs 1.2 (95% CI, 0.5-2.2) for those aged 30 years or older (P < .001). Splenectomy increased breast cancer risk (P = .01). Breast cancer detection was by self-examination in 15 cancers, by mammography in 13, and by clinical examination in 4; in 2 cancers, the mode of detection was unknown. Modified radical mastectomy was used to treat breast cancer. CONCLUSION: The increased risk of breast cancer in survivors of Hodgkin lymphoma given supradiaphragmatic radiation therapy appears to be limited to patients who are younger than 30 years at radiation therapy or to those who have undergone splenectomy. 相似文献

Association between Epstein-Barr virus and malignant lymphomas such as Burkitt's lymphoma, Hodgkin's disease(HD), nasal T/NK cell lymphoma(NTL), immunodefficiency-associated lymphoma, and pyothorax associated lymphoma (PAL) has been suggested. Among these, HD, SNL, PAL are relatively common in Japan. For HD, EBV association was found in the disease peak incidences; those are peak in older adults in Japan, older peak of the bimodal peaks in Western countries, and unimodal peak in the childhood in the developing countries. For NTL, EBV was associated with almost all cases with CD56+ phenotype and cases with polymorphic reticulosis morphology with CD56- phenotype. For PAL, most cases are EBV-associated, about 40% of these show Type B subtype, the ratio of type A EBV to type B EBV in PAL was similar to those in immunodeficiency-associated lymphomas. 相似文献

Papillary thyroid carcinoma is the most common type of thyroid cancer and accounts for almost 89.4% of all thyroid carcinomas. Hodgkin lymphoma is a heterogeneous group of neoplasms and represents 10% of lymphomas. These two cancers do not share the same risk factors. Some studies have reported the association of thyroid papillary carcinoma with lymphomas, mainly Hodgkin''s lymphoma, treated with radiotherapy. However, to our knowledge less than 10 cases have illustrated synchronous papillary thyroid carcinoma and Hodgkin lymphoma with no history of radiotherapy. We present the case of a 49‐year‐old female patient, with no history of past exposure to radiation, who was incidentally diagnosed with Hodgkin lymphoma during the work up for papillary thyroid carcinoma. Our patient had total thyroïdectomy with cervical lymphadenectomy. The histopathologic examination concluded to a papillary thyroid carcinoma of classical variant. And the lymph node dissection enabled us to diagnose not only papillary thyroid carcinoma''s lymph node metastasis, but also Hodgkin Lymphoma. This discovery of the Hodgkin lymphoma was totally incidental. The discovery of synchronous tumors in patients with papillary thyroid carcinoma has been reported in the literature. However, the diagnosis of Hodgkin through lymph node dissection for papillary thyroid carcinoma is extremely rare. This underlines the singularity and the importance of our case. The synchronous papillary thyroid carcinoma and Hodgkin lymphoma is a rare condition, which may pose significant diagnostic and treatment dilemmas. To date, there is no standardized approach due to lack of experience. The molecular mechanisms of this link are poorly understood and yet remain to be elucidated. 相似文献

Whether patients with rheumatoid arthritis (RA) have an increased risk of developing non-Hodgkin lymphoma is controversial, and opinions differ on the possible role of methotrexate in the occurrence of lymphomas in patients with RA. We report 1 T-cell lymphoma and 1 B-cell lymphoma restricted to the skin associated with Epstein-Barr virus infection that healed completely and spontaneously after discontinuation of methotrexate in a man with RA and a woman with dermatomyositis. Cutaneous infiltrating cells were infected by a replicative form of Epstein-Barr virus. After discontinuation of methotrexate, the cutaneous lesions disappeared completely in 15 days without recurrence. Discontinuation of methotrexate is necessary in patients with RA or dermatomyositis who have a lymphoproliferative disorder, and a follow-up period of several weeks should be observed before specific therapy is initiated. 相似文献

Following Epstein and colleagues' ground-breaking discovery of Epstein-Barr virus by electron microscopy of Burkitt's lymphoma cell lines, there came the observation that Epstein-Barr virus induces immortalization of B cells in vitro. Thus, initial hopes were of a virus confined to equatorial Africa with a causal link to a particular subtype of childhood lymphoma. Over the past 40 years there has been great progress towards understanding the biology and epidemiology of Epstein-Barr virus, which conclusively show that these early ideas were overly simplistic. It is now known that Epstein-Barr virus has a seroprevalence of approximately 95% worldwide, and persists for life within host B lymphocytes. Infection in New World primates leads to lymphoma and inoculation of peripheral blood mononuclear cells from Epstein-Barr virus-seropositive subjects into severe combined immunodeficiency mice results in B-cell lymphoproliferative disorders. Epstein-Barr virus is now known to be implicated in a range of lymphoid and other malignancies, and this association will be the subject of this review. 相似文献

We previously identified a relatively high frequency of B-cell proliferations along with simultaneous T-cell receptor gamma-chain gene (TRG) and immunoglobulin heavy chain gene (IGH) rearrangements in a series of angioimmunoblastic T-cell lymphoma and peripheral T-cell lymphoma, unspecified. Here, we report on a series of 74 peripheral T-cell lymphoma (PTCL) cases composed entirely of specific PTCL subtypes, including 28 cases of ALK+ anaplastic large-cell lymphoma (ALCL), 35 cases of ALK- ALCL, and 11 cases that represent other specific PTCL subtypes. We performed IGH and TRG gene rearrangement studies and in situ hybridization for Epstein-Barr virus (EBV) to determine the frequency of IGH clonality and to investigate the relationship between EBV, clonality, and associated B-cell proliferations. Using BIOMED-2 PCR assays, we detected TRG clones in 64 of 74 (86%) cases and IGH clones in 6 of 74 (8%) cases, with all IGH-positive cases exhibiting a concurrent TRG clone. Despite the detection of occasional IGH clones, there was no correlation between IGH clonality and EBV, and B-cell proliferations were not identified in any of the cases. These findings suggest that other factors contribute to IGH clonality and demonstrate that, in the absence of an associated B-cell proliferation, IGH clonality occurs infrequently (8%) in specific PTCL subtypes. 相似文献

There are many effective salvage chemotherapy regimens for the treatment of patients with Hodgkin lymphoma (HL) who relapse after or are refractory to primary therapy. All eligible patients with relapsed or refractory HL should be considered for high-dose chemotherapy with autologous stem cell transplantation. This type of therapy has become the standard of care for patients with chemosensitive disease, based on numerous phase II and two phase III clinical trials. The major considerations in the choice of salvage therapy are response rate, toxicity, and effect on subsequent stem cell collection. For patients who do not respond to salvage therapy or who relapse after autologous transplantation, available treatment options include additional salvage regimens, reduced-intensity allogeneic stem cell transplantation, and investigational agents. This review summarizes the results of various salvage chemotherapy regimens, including newer regimens that incorporate gemcitabine, in addition to novel therapies that are currently being studied in patients with relapsed or refractory HL. 相似文献

Patients with HIV-1 infection have high risk for malignant lymphoma(AIDS lymphoma). In Japanese patients, more than 90% of AIDS lymphoma are related to EBV. All 22 cases which we have experienced are non-Hodgkin's lymphoma and their histological classification is either diffuse large or diffuse immunoblastic. Their mean CD4 count is 13.6/mm3. The reports from United States and Europe show that a half of AIDS lymphoma cases are small noncleaved type and the mean CD4 count is approximately 200/mm3. This difference between Japan and other countries may be caused by difference of EBV prevalence, but precise reason is not clear. 相似文献

自身造血干细胞移植术后霍奇金淋巴瘤的复发率约为50%。复发通常发生在手术一年后,而且治疗起来并不容易。复发霍奇金淋巴瘤的自然病程可从刚开始的快速发展逐渐过渡到一个相对顽固且不活跃的缓解期。如果患者年轻,无伴发疾病且肿瘤对化疗敏感,则仍然有希望治愈。治疗方案的选择取决于一系列临床因素(如复发时间,对细胞毒疗法的敏感性以及疾病所处的阶段等)。放疗前对病史的要求:通过临床试验发现有HLA相合供体和新的因子。虽然很少有病例能获得治愈,但一系列研究结果表明,放疗、单药或联合化疗和强度减低的同种移植对病情的控制具有极好的效果。本文针对这些方法的治疗效果进行分析,并对病例收治标准、试验药以及治疗方案进行了讨论。 相似文献

Certain lymphoproliferative disorders (Burkitt's lymphoma, tropical splenomegaly, and Mediterranean lymphoma) are more frequently observed in the tropical or subtropical areas than in other parts of the world. The polymicrobial exposure of human beings in those areas to viral, bacterial and protozoal infections led to the assumption of a specific connection between these conditions and the lymphoproliferative disease. Some evidence has accumulated that the Epstein-Barr virus might be an oncogenic virus connected with the development of Burkitt's lymphoma. Repeated plasmodial infections were more tenuously thought to be associated with tropical splenomegaly and, similarly, Giardia lamblia or Vibrio cholerae infections with immunoproliferative small-intestinal disease. However, those connections are only speculative and by no means proven. Small-intestinal lymphoma represents an example of a wide spectrum of manifestations covering autonomous pre-malignant immunoproliferative stages, als well as the full-blown malignant stages. Polyclonal activation and proliferation of B-lymphocytes, as well as concomitant immunosuppression are the characteristic features of the pre-malignant situation and may be the basis for the malignant transformation of single cells. Thus, the final clinical picture resembles that of a malignant non-Hodgkin lymphoma. 相似文献
