70例结内弥漫大B细胞淋巴瘤的临床特征、免疫亚型与预后分析

背景与目的:弥漫大B细胞淋巴瘤(diffuse large B cell lymphoma,DLBCL)根据基因表达可以分成有两种不同预后的亚型:生发中心B细胞样亚型(germinal centre B-cell lymphoma,GCB)和活化B细胞样亚型(non-germinal centre B-cell lymphoma,non-GCB).本文分析原发于淋巴结内DLBCL的临床特征、免疫亚型及预后,并探讨有效的治疗方法.方法:收集本院2003年-2009年诊治的70例结内DLBCL.分析其临床资料和IPI评分,用免疫组织化学染色分成GCB和non-GCB两类免疫亚型.治疗方法包括CHOP化疗及利妥昔单抗联合CHOP (R-CHOP)免疫化疗.用Kaplan-Meier法、log-rank检验和Cox回归模型对其临床资料、免疫亚型和治疗结果进行生存分析及单因素和多因素预后分析.结果:全组患者的5年生存期(overall survival,OS)为67.8％.其中CHOP化疗患者的5年OS为58.9％,R-CHOP免疫化疗患者为77.2％,免疫化疗明显优于单纯化疗(P=O.017).免疫亚型为GCB型患者5年OS为73％,non-GCB型患者为55.9％,两者差异无统计学意义(P=0.13).但进一步分析:用CHOP化疗的non-GCB型患者5年OS明显低于GCB型患者(43.5％ vs 66.8％,P=0.042);而用R-CHOP免疫化疗的non-GCB型患者5年OS与GCB型患者差异无统计学意义(67.5％ vs 80.4％,P=0.717).在nonGCB亚型中,R-CHOP免疫化疗5年OS明显优于CHOP化疗(73.3％ vs 42.9％,P=0.02),提示R-CHOP免疫化疗能明显延长non-GCB亚型患者的长期生存.各临床因素与OS的关系:单因素分析表明年龄≥60岁、Ⅲ期、血清LDH升高、B症状和IPI≥3分均是预后不良的因素(P＜0.05).Cox多因素回归模型分析结果显示,IPI评分对OS的影响有统计学意义(P＜0.01),是独立的预后因素.结论:IPI可以预测结内DLBCL的预后和生存.采用免疫组化对DLBCL免疫分型对指导治疗有一定意义.R-CHOP免疫化疗能够显著提高结内DLBCL患者的长期生存率.

Impact of Inadequate Doses of Rituximab in the Treatment of Diffuse Large B Cell Lymphoma in Malaysian Patients

Background: The current standard treatment for patients with newly diagnosed diffuse large B cell lymphoma(DLBCL) is rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP).A significant number of patients were not treated with recommended dose of rituximab due to limited financialresources in Malaysia. This study evaluates the efficacy of R-CHOP like chemotherapy in Malaysian patients withDLBCL. Materials and Methods: The study comprised a retrospective analysis of patients with DLBCL treatedat a single centre. The outcome was compared with patients who were treated with R-CHOP like and CHOP likechemotherapy. Patients who were treated with lower dose of rituximab was subanalysed for outcome. Results:A total of 86 patients who had CHOP-like chemotherapy were included. Only 39 (45%) patients had rituximaband only 12 (29%) patients had the recommended dose. The overall response (OR) and complete response(CR) rates were 88% and 81% respectively. There was no significant difference in OR and CR in patients whohad rituximab and those without rituxmab. Those with International Prognostic Index (IPI) score of ≤2 hadsignificant higher CR rate, progression free survival (PFS) and overall survival (p<0.001). Conclusions: The lackof significant improvement in CR and DFS in our patients may be due to an inadequate dose of rituximab.

Primary diffuse large B‐cell lymphoma of the tonsil

BACKGROUND: The purpose was to evaluate the prognostic factors and treatment outcome of Indian patients with primary diffuse large B-cell lymphoma (DLBCL) of the tonsil treated at a single institution. METHODS: In all, 121 patients with DLBCL of the tonsil, treated at the Tata Memorial Hospital, Mumbai, India, from January 1990 to December 2002, were included. The median age was 45 years and the majority of patients (68%) were males. Systemic symptoms were present in 12% of patients; 28% presented with stage I and 67% had stage II disease. Treatment consisted of a combination of chemotherapy (CTh) and radiotherapy (RT) for the majority of patients (69.4%). Among those receiving RT, 64% received an RT dose of > or =45 Gy. RESULTS: After a median follow-up of 62 months, disease-free survival (DFS) and overall survival (OS) were 66.4% and 81.6%, respectively. Significant prognostic factors included: WHO performance score > or =2 (OS: 72.1% vs 95.6%, P = .016), bulky tumors (OS: 68.5% vs 86.9%, P = .001), presence of B-symptoms (OS: 36.7% vs 79.6%, P < .001), and Ann Arbor stage. On multivariate analysis; WHO performance score > or =2 (hazard ratio [HR], 4.27; 95% confidence interval [CI], 1.20-15.12), and B symptoms (HR, 6.27; 95% CI, 2.38-16.48), retained statistical significance. CTh + RT resulted in a significantly better outcome than those treated with CTh alone (OS: 85.7% vs 70.7%, P = .008). The complete response (P = .053), DFS (P = .039), and OS (P = .014) rates were significantly better for patients receiving an RT dose > or =45 Gy. CONCLUSIONS: Tumor bulk, WHO performance score, the presence of B symptoms, and Ann Arbor stage significantly influence outcome. A combined modality treatment, consisting of CTh and RT (with an RT dose of > or =45 Gy), results in a satisfactory outcome in patients with this uncommon neoplasm.     

Response and survival benefit with chemoimmunotherapy in Epstein‐Barr virus‐positive diffuse large B‐cell lymphoma

Epstein‐Barr virus (EBV)‐positive diffuse large B‐cell lymphoma (DLBCL) is a haematologic malignancy with poor prognosis when treated with chemotherapy. We evaluated response and survival benefits of chemoimmunotherapy in EBV‐positive DLBCL patients. A total of 117 DLBCL patients were included in our retrospective analysis; 33 were EBV‐positive (17 treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R‐CHOP] and 16 with CHOP), and 84 were EBV‐negative (all treated with R‐CHOP). The outcomes of interest were complete response (CR) and overall survival (OS) in EBV‐positive DLBCL patients (R‐CHOP versus CHOP) and in DLBCL patients treated with R‐CHOP (EBV‐positive vs EBV‐negative). There were no differences in the clinical characteristics between EBV‐positive and EBV‐negative DLBCL patients. Among EBV‐positive DLBCL patients, R‐CHOP was associated with higher odds of CR (OR 3.14, 95% CI 0.75‐13.2; P = .10) and better OS (hazard ratio 0.30, 95% confidence interval [CI] 0.09‐0.94; P = .04). There were no differences in CR rate (OR 0.52, 95% CI 0.18‐1.56; P = .25) or OS (hazard ratio 0.93, 95% CI 0.32‐2.67; P = .89) between EBV‐positive and EBV‐negative DLBCL patients treated with R‐CHOP. Based on our study, the addition of rituximab to CHOP is associated with improved response and survival in EBV‐positive DLBCL patients. Epstein‐Barr virus status does not seem to affect response or survival in DLBCL patients treated with R‐CHOP.     

Addition of rituximab is not associated with survival benefit compared with CHOP alone for patients with stage I diffuse large B-cell lymphoma

Background

The role of rituximab in combination with CHOP regimen in patients with stage I diffuse large B-cell lymphoma (DLBCL) remains to be defined. We aimed to compare CHOP plus rituximab (R-CHOP) with CHOP alone and determine the value of radiotherapy in these patients.

Methods

Between 2003 and 2009, 140 untreated patients with stage I DLBCL were retrospectively analyzed in this study.

Results

Seventy-eight patients were treated in R-CHOP group and 62 in CHOP group. Ninety-one patients received additional radiotherapy at the end of chemotherapy. The different treatment groups were well-balanced with respect to baseline characteristics. Complete response (CR) rate was 77% both in R-CHOP and CHOP groups (P=0.945). After a median follow-up period of 56 months, patients received R-CHOP regimen had similar 5-year progression-free survival (PFS) (76% vs. 85%; log-rank P=0.215) and 5-year overall survival (OS) (90% vs. 96%; log-rank P=0.175) compared with those with CHOP alone. Patients with radiotherapy had significantly increased 5-year PFS compared with those who had chemotherapy alone (86% vs. 71%; log-rank P=0.005). At multivariate analysis, patients who had CR (P=0.008) and received radiotherapy (P=0.003) were significantly associated with superior PFS.

Conclusions

CHOP alone could be as effective as R-CHOP regimen and additional radiotherapy would be necessary for stage I or stage I non-bulky DLBCL patients.     

Mean platelet volume predicts prognosis in patients with diffuse large B‐cell lymphoma

To determine the prognostic value of baseline mean platelet volume (MPV) in diffuse large B‐cell lymphoma (DLBCL) patients. We retrospectively analyzed 161 DLBCL patients who received R‐CHOP chemotherapy. The associations between MPV and clinicopathological factors were assessed. A low MPV (MPV ≤ 9.1 fl, cut‐off was calculated by receiver operating characteristics) was not associated with any other clinicopathological factors. * Patients with MPV ≤ 9.1 fl experienced a shorter progression‐free survival (PFS) (2‐year PFS rate, 60.6% vs 84.0%, P = 0.003) and overall survival (OS) (2‐year OS rate, 70.4% vs 87.9%, P = 0.030), compared with those with MPV > 9.1 fl. The multivariate analysis demonstrated that MPV ≤ 9.1 fl was an independent prognostic factor of OS (Hazard Ratio [HR] = 0.588, P = 0.045) and PFS (HR = 0.456, P = 0.010). Therefore, we demonstrated that low baseline MPV is an independent prognostic marker of poor outcome in patients with DLBCL.
