Follicular large cell lymphoma: long-term follow-up of 62 patients treated between 1973-1981.

Purpose:Investigators disagree on whether follicular large celllymphoma (FLCL) behaves like other follicular lymphomas, with no plateau inthe survival curve, or as a more aggressive but potentially curable lymphoma.We reported in 1984 results for 62 FLCL patients treated at our institution;the current report updates those results. Patients and methods:Sixty-two patients referred from1973–1981, including fifteen (24%) patients with Ann Arbor stageI–II and forty-seven (76%) with stage III–IV FLCL. Sevenpatients received radiation (XRT) alone, forty patients XRT and chemotherapy,and fifteen patients received chemotherapy alone. Results:The median follow-up was 14.7 years. The median survivalwas 5.1 years, with 21% alive at 15 years. The failure-free survival(FFS) at 10 years was 31%. Univariate analysis revealed that age, AnnArbor stage, and the International Index correlated with survival. Performancestatus, number of platelets, and LDH correlated with failure-freesurvival. Conclusions:FLCL responds to doxorubicin-based regimens similarlyto diffuse large cell lymphoma. Patients with FLCL have the potential forprolonged failure-free survival. Variables that predict the survival inaggressive lymphomas apply as well in this type of lymphoma.     

Follicular lymphoma: prognostic factors for response and survival

One hundred forty-eight patients with newly diagnosed follicular lymphoma were treated over a 12-year period. Twenty-two patients received radiotherapy for stage I and II disease, followed by adjuvant chemotherapy in 14 patients. One hundred thirteen were treated at presentation with short courses of chemotherapy, most often with single-agent chlorambucil for bulky stage II and stages III and IV disease. Thirteen patients were managed expectantly until there was evidence of disease progression. The median survival was 9 years. Patients treated with radiotherapy for stage I and II disease had an 83% relapse-free survival, but those with bulky stage II or stages III and IV disease treated with chemotherapy pursued a remitting and relapsing course with a 70% response rate at initial and subsequent retreatments, but a median duration of remission of 4 years in stage III and 1 year in stage IV disease (P = .041). Patients were observed in relapse and retreatment was administered as appropriate, once every 33 months on average. Poor prognosis patients could be identified by a combination of the presentation characteristics: B symptoms, hepatosplenomegaly, anemia, and abnormal liver function. These factors predicted a poor response to treatment and correlated with a short survival. Histologic subgroups were not associated with differences in survival, but transformation to a diffuse high-grade lymphoma was observed in 23 of the 72 patients (32%) at risk, with a median follow-up of 6 years and 6 months, and was associated with a very poor prognosis. The present treatment strategy has proved successful for most patients with localized disease and those older patients with indolent small volume disseminated follicular lymphoma. New approaches are being investigated for the younger poor prognosis patients.     

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     

Follicular lymphoma international prognostic index

Opinion statement Although numerous treatment approaches are proposed for patients with follicular lymphoma, criteria to help in choosing a treatment for a given patient and for comparing trial results are lacking. Several retrospective studies have analyzed prognostic factors, but their conclusions rely on limited numbers of patients treated during long periods, and their results are discordant. The Follicular Lymphoma International Prognostic Index was designed from the data recorded over 8 years of nearly 5000 patients registered worldwide. Five factors are used (age, Ann Arbor stage, number of nodal sites, serum lactate dehydrogenase level, and hemoglobin level) to build a threecategory index. This index, together with new biologic markers such as gene profiling and proteomics, could help provide an optimal treatment option for patients with follicular lymphoma.     

Clinical prognostic factors of diffuse large B cell non-Hodgkin lymphoma: A retrospective study

BackgroundDiffuse large B-cell lymphoma (DLBCL) is the most common subtype of NHL in Egypt. It represents about 49% of NHL presenting to the National Cancer Institute (NCI), Cairo University. CHOP regimen is the standard treatment used for NHL since the 1970s with only 30–40% overall survival. Recently, integration of Rituximab became a standard of care for patients with DLBCL. However, its widespread use in developing countries is still limited by the lack of financial coverage. Clinical prognostic factors, as well as the pathological markers, are mandatory to individualize treatment.AimThe aim of the study was to evaluate the clinical risk stratification models including the age adjusted International prognostic index (aaIPI), patients profile and dose intensity (DI) of Cyclophosphamide and Doxorubicin as effective tools for predicting the outcome and prognosis of our DLBCL patients treated with first line CHOP regimen.Patients and methodsThis retrospective study included 224 patients with diffuse large B cell lymphoma who were treated with 3–8 cycles of CHOP regimen at the Medical Oncology Department, NCI, Cairo University during the time period from 1999 to 2006.ResultsOne hundred and seventy-eight patients (79.5%) achieved CR after the CHOP regimen with an observation period of 51 months. The median survival time was 12 months. The OS and DFS at 2 years were 82% and 68.8%, respectively. The univariate analysis of predictive factors for response to treatment showed that the CR rate was significantly affected by aa-IPI and its elements (performance status, stage &; LDH), extranodal lesions and DI of Cyclophosphamide and Doxorubicin. The CR rate was 96.9%, 91.2%, 73.9% and 55.6% in cases with aa-IPI 0, 1, 2 and 3, respectively (p < 0.001) and it was 82.4%, 81.9% versus 50% in cases with no extranodal site, one extranodal site and two extranodal sites, respectively (p = 0.01). As regard DI of Cyclophosphamide, with DI below or equal to the median (249 mg/m²/week) the CR rate was 69%, while with DI above the median the CR rate was 87.7% (p = 0.001). For Doxorubicin, the CR rate was 72.3% with DI below or equal to the median (16.5 mg/m²/week), however, it was 86.6% with DI above the median (p = 0.008). The OS rate was significantly affected by aa-IPI as it was 89.8% in cases of aa-IPI 0 + 1 versus 75.8% in those of aa-IPI 2 + 3 (p = 0.03). DI of Cyclophosphamide and Doxorubicin significantly influenced the OS. The OS rate was 74% with DI of Doxorubicin below or equal to the median versus 96% in cases with DI above the median (p = 0.02). For Cyclophosphamide the OS rate was 72.7% with DI below or equal to the median versus 96.3% in cases with DI above the median (p = 0.01). The tumor bulk (with a median tumor size of 5 cm) affected the OS, which was 91.23% versus 86.8% in the tumor bulk less than and more than or equal to the median, respectively (p = 0.05). By multivariate analysis of predictive factors for response to treatment, the CR rate was significantly affected by the number of extranodal sites and the clinical staging of diffuse large B cell lymphoma. However, OS rate was strongly associated with the bulk of the tumor and the clinical staging of diffuse large B cell lymphoma.ConclusionDI of Cyclophosphamide and Doxorubicin is important in the future treatment regimen plan for DLBCL especially in high risk cases. In addition to aa-IPI and its elements, extra nodal sites and bulk of the tumor proved to be significant predictors and prognostic factors for DLBCL treatment outcome.

Large bowel lymphoma: an analysis of prognostic factors and therapy in 53 patients

BACKGROUND AND OBJECTIVES: We performed a retrospective analysis to assess the influence of different prognostic factors, including the International Prognostic Index (IPI), that can predict the outcome in patients with primary large bowel lymphoma (Stage IE) treated with combined therapy (surgery followed by chemotherapy). METHODS: All patients were treated with radical surgery followed by six cycles of combined chemotherapy: CHOP-Bleo (cyclophosphamide, doxorubicine, vincristine, prednisone, and bleomycin) or variants (epirubicin instead of doxorubicin). In all cases, an multivariate analysis was performed to identify prognostic factors (if any), including IPI, that can influence outcome. RESULTS: According to the IPI, event-free survival (EFS) and overall survival were 85% and 87%, respectively, in patients with low and low-intermediate clinical risk that was not statistically significant when compared to patients at high and high-intermediate clinical risk: 69% and 76% (P = 2). Multivariate analysis failed to demonstrate the influence of multiple prognostic factors that were analyzed. CONCLUSIONS: Combined therapy appears to be an excellent therapeutic approach in this group of patients with prolonged EFS and survival, and without late toxicity. However, no prognostic factors, including IPI, could be identified to define the best therapy, probably because the number of patients, even in large series, is limited. Multicentric studies are necessary to identify prognostic factors to define therapy and outcome in this rare clinical presentation of malignant lymphoma.     

High-dose therapy in diffuse large cell lymphoma: results and prognostic factors in 452 patients from the GEL-TAMO Spanish Cooperative Group.

BACKGROUND: The purpose of this study was to analyse the results and prognostic factors influencing overall survival (OS) and disease-free survival (DFS) in 452 patients diagnosed with diffuse large cell lymphomas (DLCL) treated with high-dose therapy (HDT) included in the Grupo Espa?ol de Linfomas/Trasplante Autólogo de Médula Osea (GEL-TAMO) Spanish registry. PATIENTS AND METHODS: At transplantation, median age was 42 years (range 15-73), 146 patients (32%) were transplanted in first complete remission (1st CR), 19% in second CR (2nd CR) and 47% had active disease: sensitive disease in 157 (35%) patients [95 were in first partial remission (1st PR) and 62 in second PR (2nd PR)] and refractory disease in 55 (12%) patients. Age-adjusted International Prognostic Index (IPI) was 2 or 3 in 51 patients (12%). Conditioning regimen consisted of BEAM (carmustine, etoposide, cytarabine and melphalan) in 39% of patients, BEAC (carmustine, etoposide, cytarabine and cyclophosphamide) in 33%, CBV (carmustine, etoposide and cyclophosphamide) in 10% and cyclophosphamide plus total body irradiation (TBI) in 12%. RESULTS: Estimated overall survival (OS) and disease-free survival (DFS) at 5 years were 53% and 43%, respectively. The transplant-related mortality was 11% (53 cases). By multivariate analysis three variables significantly influenced OS and DFS: number of protocols to reach 1st CR, disease status at transplant and TBI in the conditioning regimen. Age-adjusted IPI at transplantation also influenced OS. CONCLUSIONS: Prolonged OS and DFS can be achieved in patients with DLCL after HDT and our results suggest that the best line of chemotherapy should be used up-front in patients considered as candidates for HDT in order to obtain an early CR. Resistant patients are not good candidates for HDT and they should be offered newer strategies. Finally, polichemotherapy conditioning regimens offer better results compared with TBI.     

Survival after progression in patients with follicular lymphoma: analysis of prognostic factors.

BACKGROUND: The purpose of this study was to identify prognostic parameters for patients with follicular lymphoma (FL) in first progression/relapse. These would be useful for selection of high-risk patients for inclusion in trials aimed at determining the effect of new treatment approaches in such patients. PATIENTS AND METHODS: Ninety patients (48 male, 42 female, median age 56 years) diagnosed with FL, in a single institution during a 20 year period and relapsing/progressing after an initial response to therapy, were recruited. The main end-point of the study was survival from progression (SFP). Univariate and multivariate analyses were performed, including among the predictive variables the response duration (RD) after the initial treatment and the main features of the patients at the first progression or relapse. RESULTS: Five-year SFP was 47% (95% confidence interval 35% to 58%). Patients with RD following initial therapy >2 years had a longer SFP (5-year SFP 63 versus 33%, P = 0.012). Other variables with prognostic interest for SFP were stage at diagnosis and the following variables at relapse: age, bulky disease, performance status, serum lactate dehydrogenase level, serum beta2-microglobulin level, bone marrow involvement, stage and International Prognostic Index rating. In the multivariate analysis, poor performance status at progression and a RD <2 years were the most important unfavorable variables to predict SFP. CONCLUSION: In patients with FL, RD along with performance status at progression are features that predict SFP. These variables could thus be useful to select candidates for experimental treatments.     

Immunophenotype and intermediate‐high international prognostic index score are prognostic factors for therapy in diffuse large B‐cell lymphoma patients

BACKGROUND.

The development of gene expression profiling and tissue microarray techniques have provided more information about the heterogeneity of diffuse large B‐cell lymphoma (DLBCL), enabling categorization of DLBCL patients into 3 prognostic groups according to cell origin (but independently from the International Prognostic Index [IPI] score): germinal center (GCB), activated B‐cell (ABC), and not classified (NC) diffuse large B‐cell lymphoma. This study investigated the role of immunohistochemical discrimination between GCB and ABC&NC‐DLBCL subtypes in identifying those high‐risk patients who may benefit from a more aggressive first‐line therapeutic approach.

METHODS.

From February 2003 to August 2006, 45 newly diagnosed DLBCL patients, with IPI≥2, were considered eligible for this study: 13 had a GCB, 8 an ABC, and 24 a NC‐DLBCL. GCB patients received 6 courses of rituximab, cyclophophosphamide, doxorubicin, vinicristine, and prednisone (R‐CHOP) chemotherapy, with a subsequent, autologous stem cell transplantation in case of partial response. All ABC and NC‐DLBCL patients received 6 R‐CHOP cycles and autologous stem cell transplantation.

RESULTS.

Complete response rate for each treatment arm was 84.6% for GCB and 89.7% for ABC&NC‐DLBCL (P = .50), with a continuous complete response rate of 81.8% and 84.6%, respectively (P = .59). Projected 4‐year overall survival is 100% for GCB and 82% for ABC&NC patients (P = .12). Progression‐free survival is 77% and 79% (P = .7), respectively.

CONCLUSIONS.

The autologous stem cell transplantation consolidation in the ABC&NC‐DLBCL subtypes induced the same rate of complete response (and similar progression‐free survival rate) compared with GCB‐DLBCL. In ABC&NC‐DLBCL patients the authors observed a complete response rate of 89.7% vs. 84.6% in the GCB‐DLBCL subset, without any significant difference in progression‐free survival rate.

Clinicopathological prognostic indicators in 107 patients with diffuse large B‐cell lymphoma transformed from follicular lymphoma

Follicular lymphoma (FL) frequently transforms into diffuse large B‐cell lymphoma (DLBCL). To clarify the associated clinicopathological prognostic parameters, we examined the correlation of 11 histopathological parameters with progression‐free survival (PFS) and overall survival (OS) in 107 consecutive patients who had DLBCL with pre‐existing (asynchronous) or synchronous FL. The patients comprised 58 men and 49 women with a median age of 56 years. For DLBCL, the complete response rate was 81%, overall response rate was 88%, and 5‐year PFS and OS rates were 55% and 79%, respectively. Immunohistochemical analysis of the DLBCL component revealed the following positivity rates: CD10, 64%; Bcl‐2, 83%; Bcl‐6, 88%; MUM1, 42%; GCB, 82%; cMyc index ≥80%, 17%; and Ki‐67 index ≥90%, 19%. IGH/BCL2 fusion was positive in 57% of DLBCL cases. In univariate analyses, asynchronous FL and DLBCL (24%, P = 0.021), 100% proportion of DLBCL (29%, P = 0.004), Bcl‐2 positivity (P = 0.04), and high Ki‐67 index (P = 0.003) were significantly correlated with shorter PFS. Asynchronous FL and DLBCL (P = 0.003), 100% proportion of DLBCL (P = 0.001), and high Ki‐67 index (P = 0.004) were significantly correlated with shorter OS. In a multivariate analysis, asynchronous FL and DLBCL (P = 0.035) and 100% proportion of DLBCL (P = 0.016) were significantly correlated with shorter OS. Thus, asynchronism and 100% proportion of DLBCL, that is, FL relapsed as pure DLBCL, or FL and DLBCL at different sites, were significant predictors of unfavorable outcome of patients with DLBCL transformed from FL.     

Anaplastic large cell lymphoma: a clinicopathologic analysis

The clinicopathologic features of anaplastic large cell lymphoma (ALCL) are reviewed. ALCL is a heterogeneous group of tumours, and histologic examination alone is not adequate in providing useful prognostic information. However, using a combination of clinical, phenotypic, and genotypic features, several distinct clinicopathologic entities have been identified. A subset of ALCL as presently defined is characterized by a balanced translocation, t(2;5)(p23;q35), resulting in a novel fusion protein (NPM-ALK) that can be readily detected by immunohistochemical methods using antibodies against the ALK protein. Detection of ALK protein, along with other methods for demonstrating the t(2;5), has assisted in identifying a distinct biologic entity within the heterogeneous group of ALCL with significant prognostic implications. It is important to separate these from cases of ALK-negative ALCL, which have a poorer prognosis, and cases of primary cutaneous ALCL, which have an excellent prognosis.     

原发性骨淋巴瘤的疗效和预后因素分析

目的 回顾分析原发性骨淋巴瘤(PBL)患者的疗效和预后因素.方法 1994-2009年间本中心收治的PBL患者31例,均经病理证实为非霍奇金淋巴瘤,其中Ⅰ E、Ⅱ E、ⅣE期分别为22、4、5例.全组单纯手术1例、单纯放疗1例、单纯化疗2例、术后化疗4例、放化疗23例,放疗剂量中位数字为50 Gy.结果 随访时间中位数45.2个月.随访率为83.9%.随访满10年者9例.全组治疗后5、10年总生存率分别为92%、92%,无进展生存率分别为79%、70%.非联合放化疗组的完全缓解率为50%、进展或复发为2/8、复发时间中位数为6.8个月,联合放化疗组相应为65%、13%、39.1个月.单因素分析显示年龄≤50岁(χ2=5.32,P=0.021)及美国东部肿瘤协作组(ECOG)体力状况(PS)评分0～1分(χ2=5.48,P=0.019)为生存预后因素,国际预后指数评分≤1分(χ2=7.81,P=0.005)及ECOG PS评分0～1分(χ2=18.70,P=0.000)为无进展生存预后因素.结论 PBL患者预后良好,放化疗应作为首选治疗方法,放疗剂量≥40 Gy较安全可行.年轻及一般状况较好患者预后更好.

Abstract：

Objective To retrospectively analyze the treatment results and prognostic factors in patients with primary bone lymphomas (PBL).Methods Thirty-one patients with PBL treated between April 1994 and May 2009 at Sun Yat-sen University Cancer Center were analyzed.All patients were diagnosed by pathology.Twenty-two patients had stage Ⅰ E, 4 patients had stage Ⅱ E and 5 patients had stage ⅣE diseases.One patient was treated with surgical resection alone, 1 patient with radiotherapy (RT) alone, 2 patients with chemotherapy (CT) alone and 4 patients with resection followed by chemotherapy.The remaining 23 patients received CT combined with RT.The median radiation dose was 50 Gy.Results The median follow-up time was 45.2 months.The follow-up rate was 83.9%.Nine patients had a follow-up time of 10 years.The 5-year and 10-year overall survival rates were 92% and 92%, respectively.The 5-year and 10-year disease-free survival rates were 79% and 70%, respectively.In the group who received non-combined chemoradiotherapy, the complete response rate was 50%, the incidence of progression or recurrence was 2/8 and the median recurrence time was 6.8 months.In the group who received combined chemoradiotherapy, the complete response rate was 65%, the incidence of progression or recurrence was 13% and the median recurrence time was 39.1 months.In univariate analyses, favorable prognostic factors for survival included age≤50 years (χ2=5.32,P=0.021) and ECOG PS score 0-1(χ2=5.48,P=0.019).Favorable prognostic factors for DFS included IPI score≤1(χ2=7.81,P=0.005) and ECOG PS score 0-1(χ2=18.70,P=0.000).Conclusions Treatment results of patients with PBL can be generally well.CT combined with RT appears to be the treatment of choice.RT dose ≥40 Gy is safe and feasible.Younger age and better performance status are associated with a better outcome.

目的:研究套细胞淋巴瘤（MCL)患者的临床特点及预后相关因素,进一步全面评估病情,探索个体化治疗。方法:回顾性分析2012年1 月至2016年12 月经我院病理科确诊的51例MCL 患者的临床特点、住院20例患者的预后分层和不同化疗方案的近期及远期疗效,并进行随访观察。结果:20例住院治疗患者中,R-Hyper-CVAD组及R-CHOP样组的ORR（分别为100%、100%）均高于其未联合美罗华组（分别为50%、40%）;MIPI评分中,低危组ORR为75.0%,明显高于中危组（16.6%）;CD5-患者CR、PR均高于CD5+患者;Ki67≥30%患者CR率（20%）大于Ki67＜30%组（11%）,PR率则相反;Ki67＜30%患者3年OS明显高于Ki67≥30%患者,有统计学差异,而PFS无统计学差异;MIPI分组中,低危组3年OS明显高于中高危组,有统计学差异,PFS无统计学差异;美罗华组无论OS还是PFS均高于非美罗华组;Hyper-CVAD组与非Hyper-CVAD组OS、PFS均无统计学差异。结论:美罗华联合化疗治疗MCL的疗效是肯定的,绝大多数患者能够耐受减低剂量的Hyper-CVAD A及B方案化疗,但统计学显示与非Hyper-CVAD组无明显差异,可能与病例数偏少相关,需要更多大样本的循证医学的支持。
