背景:Bcl-2基因转录异常与结内弥漫大B细胞淋巴瘤(DLBCL)关系密切,对Bcl-2与原发性胃肠道DLBCL(PGI-DLBCL)的关系则缺乏充分研究。目的:探讨PGI-DLBCL中Bcl-2基因扩增和蛋白表达与肿瘤临床病理特征、免疫表型和预后的关系。方法:采集136例手术治疗PGI-DLBCL患者的临床资料,电话随访生存信息。以荧光原位杂交技术检测肿瘤组织Bcl-2基因扩增,免疫组化法检测Bcl-2蛋白表达,分析两者与肿瘤临床病理特征、免疫表型和预后的关系。结果:136例患者中,33例(24.3%)Bcl-2基因扩增阳性,90例(66.2%)Bcl-2蛋白表达阳性;基因扩增与肿瘤原发部位、Ann Arbor分期、血清乳酸脱氢酶水平、B症状、国际预后指数(IPI)评分相关(P0.05),蛋白表达与肿瘤原发部位和免疫表型相关(P0.05)。Bcl-2基因扩增阳性患者和免疫表型为非GCB型的Bcl-2蛋白表达阳性患者5年总生存率(OS)分别显著低于相应阴性患者(41.5%对71.5%,P0.05;54.6%对84.6%,P0.05)。Bcl-2基因扩增或蛋白表达阳性患者中,CHOP化疗的5年OS显著低于利妥昔单抗联合CHOP化疗(48.6%对80.3%,P0.05;66.4%对83.4%,P0.05)。结论:检测Bcl-2基因扩增对PGI-DLBCL的预后判断具有重要意义,检出Bcl-2基因扩增者预后较差。非GCB型PGI-DLBCL中,Bcl-2蛋白表达与预后不良相关。利妥昔单抗可提高Bcl-2基因扩增或蛋白表达阳性患者的生存率。 相似文献

CD4+CD56+ malignancy is a rare neoplasm with a typical clinical pattern, an aggressive course and high early relapse rate despite good initial response to chemotherapy. In this review, the impact of different therapeutic approaches on clinical outcome has been studied. We evaluated 91 published cases and our own six patients in terms of clinical features, immunophenotype/cytogenetics and treatment outcome. Treatment was divided into four groups: (A) chemotherapy less intensive than CHOP; (B) CHOP and CHOP-like regimens; (C) therapy for acute leukemia; (D) allogeneic/autologous stem cell transplantation. The median overall survival was only 13 months for all patients. Patients with skin-restricted disease showed no difference in the overall survival from patients with advanced disease (17 and 12 months, respectively). Age >/=60 years was a negative prognostic factor. Age-adjusted analysis revealed improved survival after high-dose chemo/radiotherapy followed by allogeneic stem cell transplantation when performed in first complete remission. This therapeutic approach should be recommended for eligible patients with CD4+CD56+ malignancy. For older patients the best treatment option is still unknown. 相似文献

This study aims to retrospectively analyze the clinical characteristics, treatments, and prognosis of aggressive peripheral T cell lymphoma (PTCL) patients with a lymphoma-associated hemophagocytosis syndrome (LAHS). We compared the clinical features and the overall survival (OS) rates of 159 PTCL patients with and without LAHS as well as the treatment outcomes of these patients with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) or intensive chemotherapy regimens. We observed that in 23 % (36/159) patients PTCL was associated with LAHS. Different subtypes of PTCL in LAHS patients were diagnosed and peripheral T cell lymphoma, not otherwise specified (PTCL-NOS) was the main subtype (78 %). The median survival rates of the LAHS and non-LAHS groups were 3 and 16 months, respectively. The elevated rates of serum β2-microglobulin, ferritin, fasting triglycerides, and hypofibrinogen levels were higher in the LAHS group, so were bone marrow involvement, liver dysfunction, hepatosplenomegaly, and B symptoms. Three patients who were treated with a plasma exchange had a longer survival time. There was no statistically significant difference in the OS rates between the intensive chemotherapy and CHOP regimen groups (P?>?0.05). PTCL patients with LAHS had a poorer prognosis. Awareness of the clinical symptoms and laboratory findings are crucial in order to diagnose LAHS in an early stage and repeated biopsies of multiple bone marrows from different locations in those patients without enlargement of superficial lymph nodes are necessary to improve the diagnosis. Intensive chemotherapy due to its severe toxicity was not obviously advantageous for the OS rate compared to the CHOP regimen. 相似文献

The influence of the germinal-center B-cell (GCB) and the non-GCB phenotypes of diffuse large B-cell lymphoma (DLBCL) on the
outcome of 92 patients treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like chemotherapy,
with or without rituximab was determined in this study. The differentiation between the GCB and non-GCB types was arrived
at by immunohistochemistry using previously published criteria. Thirty-nine patients had the GCB and 53 had the non-GCB type
of DLBCL. Forty-nine patients were treated with rituximab and chemotherapy; 43 were treated with chemotherapy alone. The GCB
and non-GCB group did not differ in their international prognostic index factors and score, presence of bulky disease, or
frequency of rituximab treatment. Median follow-up of the surviving patients was carried out for 37 months. There was no difference
between the GCB and non-GCB groups in both overall response rates (67 vs. 70%, respectively) and estimated rates of 3-year
event-free (46 vs. 49%, respectively) and overall (54 vs. 56%, respectively) survival. In addition, no differences of the
outcomes were observed between the subgroups treated with or without rituximab. The patients of this study with immunohistochemically
determined GCB-type DLBCL did not have an improved prognosis, irrespective of whether they had received rituximab or not. 相似文献

The means of optimally managing very elderly patients with diffuse large B‐cell lymphoma (DLBCL) has not been established. We retrospectively analyzed 252 patients aged 80‐100 years, diagnosed with DLBCL or grade 3B follicular lymphoma, treated in 19 hospitals from the GELTAMO group. Primary objective was to analyze the influence of the type of treatment and comorbidity scales on progression‐free survival (PFS) and overall survival (OS). One hundred sixty‐three patients (63%) were treated with chemotherapy that included anthracyclines and/or rituximab, whereas 15% received no chemotherapeutic treatment. With a median follow‐up of 44 months, median PFS and OS were 9.5 and 12.5 months, respectively. In an analysis restricted to the 205 patients treated with any kind of chemotherapy, comorbidity scales did not influence the choice of treatment type significantly. Independent factors associated with better PFS and OS were: age < 86 years, cumulative illness rating scale (CIRS) score < 6, intermediate risk (1‐2) R‐IPI, and treatment with R‐CHOP at full or reduced doses. We developed a prognostic model based on the multivariate analysis of the 108 patients treated with R‐CHOP‐like: median OS was 45 vs. 12 months (P = .001), respectively, for patients with 0‐1 vs. 2‐3 risk factors (age > 85 years, R‐IPI 3‐5 or CIRS > 5). In conclusion, treatment with R‐CHOP‐like is associated with good survival in a significant proportion of patients. We have developed a simple prognostic model that may aid the selection patients who could benefit from a curative treatment, although it needs to be validated in larger series. 相似文献

Objectives: Primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL) is a rare hematological malignancy with limited results on carcinogenesis and clinical characteristics. The aims of the current study were to examine mitotic arrest deficiency protein 2 (Mad2) expressions in PGI-DLBCL, and assess its association with Ki-67 expression, Helicobacter pylori (H. pylori) infection, BCL-6 gene rearrangement, and clinicopathological variables.Methods: Cancer tissues from 38 PGI-DLBCL patients were examined for Mad2, Ki-67, and H. pylori expression by immunohistochemistry, using normal gastrointestinal tissues and nodal DLBCL as controls. BCL-6 gene translocation was analyzed by fluorescence in situ hybridization (FISH), and Mad2 expression status was evaluated along with clinicopathological characteristics.Results: Mad2 expression was increased in PGI-DLBCL patients when compared with controls. The expression of Mad2 was 51.55?±?22.88% in PGI-DLBCL, which was higher than reactive lymph node (28.77?±?10.89%) and lymphoid nodule in normal gastrointestinal tissue (26.41?±?11.30%) (P?=?0.002), while it was comparable to nodal DLBCL (57.23?±?20.79%) (P?=?0.358). Mad2 overexpression had a positive correlation with Ki-67 proliferation index (r?=?0.55, P?=?0.01) in PGI-DLBCL, and patients with BCL-6 gene rearrangement had lower Mad2 expression (P?=?0.032) than patients with intact BCL-6, while no relation was found between Mad2 expression and H. pylori infection. PGI-DLBCL patients with higher Mad2 expression had lower estimated disease-free survival (DFS) (17.10% vs. 53.00%) (P?=?0.049). However, no correlation was found between Mad2 expression levels and overall survival (OS) (P?=?0.443).Conclusions: Aberrant Mad2 expression was associated with cell proliferation and genetic instability, which may contribute to the carcinogenesis of PGI-DLBCL. Mad2 overexpression indicated a poor DFS and may be a potential biomarker for estimating prognosis for PGI-DLBCL patients. 相似文献

Background: Surgical resection is considered a crucial treatment in patients with primary colonic lymphoma, but combining surgery with chemotherapy has provided additional therapeutic benefits in some studies. To further explore the optimal therapeutic approach in different clinical scenarios, we reviewed cases with localized large‐cell lymphoma and analyzed the factors related to the outcomes. Patients and methods: The 74 cases diagnosed between February 1979 and October 2010 were retrospectively reviewed for clinical features, laboratory findings, and pathological diagnosis. The outcomes were correlated with their demographics and different treatment modalities. Results: Of the 74 cases, only the patients who had complete tumor resection had significantly improved progression‐free survival (PFS). The patients treated with resection and chemotherapy had better overall survival (OS) and PFS than those treated with resection alone. The OS and PFS of the patients who were treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy without surgery were similar to those of patients treated with CHOP and resection, but the patients treated with resection followed by cyclophosphamide, vincristine, and prednisone (COP) chemotherapy had significantly better OS and PFS than the patients treated with COP chemotherapy alone. For patients with diffuse large B‐cell lymphoma (DLBCL), rituximab‐based chemotherapy with or without resection had similar OS and PFS. Conclusions: We conclude that chemotherapy alone provides similar therapeutic effect compared with surgery and chemotherapy and that surgical resection can be spared if an endoscopic diagnosis could be made. 相似文献
