利妥昔单抗联合CHOP化疗上调钙网蛋白表达提高对NHL的疗效

目的:探讨利妥昔单抗(rituximab)联合CHOP化疗治疗B细胞非霍奇金淋巴瘤(non-Hodgkin's lymphoma,NHL)的临床疗效及其对钙网蛋白(calreticulin,CRT)表达的影响.方法:选取南通大学附属医院2008年7月至2011年2月期间48例初治B细胞NHL,分为利妥昔单抗联合CHOP化疗组(R-CHOP组,25例)和CHOP组(23例)两组,6个疗程后比较两组患者的临床疗效、不良反应,以及外周血中CD20+B细胞表面CRT的表达.结果:R-CHOP组B细胞NHL患者完全缓解率为80.0％,总有效率为92.0％;CHOP组完全缓解率为56.5％,总有效率为69.6％;R-CHOP组患者完全缓解率以及总有效率高于CHOP组(P＜0.05).两组间不良反应相似,R-CHOP联合治疗没有增加NHL患者治疗后的不良反应.R-CHOP组患者治疗后外周血中CD20+B细胞表面CRT的表达明显高于CHOP组[(255.00 ±5.57) vs (216.00 ±3.61),P＜0.05].结论:利妥昔单抗联合CHOP化疗治疗B细胞NHL较常规CHOP化疗效果好,可能与联合治疗上调CRT表达有关.     

R-CHOP与CHOP方案治疗初治弥漫大B细胞型淋巴瘤在中国的多中心随机对照研究

背景与目的:CHOP化疗方案是目前治疗弥漫性大B细胞型非霍奇金淋巴瘤(non-HodgkinTslymphoma,NHL)的标准方案。利妥昔单抗(美罗华)作为一种针对CD20抗原表达阳性的B细胞的嵌合型单克隆抗体,对弥漫性大B细胞型淋巴瘤具有良好的疗效。在欧洲和美国,利妥昔单抗联合标准化疗方案治疗进展型NHL已经获得批准。本研究旨在比较利妥昔单抗加标准CHOP方案与标准CHOP方案治疗中国人CD20阳性的弥漫大B细胞型NHL患者的疗效和安全性。方法:2003年9月至2004年11月在全国9个研究中心进行,共有63例患者入组,其中CHOP组32例,R-CHOP组31例。所有入组患者均签署并提供知情同意书。CHOP组患者接受每3周为1个疗程共6个疗程的CHOP方案治疗;R-CHOP组患者在每个疗程开始的第1天联用利妥昔单抗的CHOP治疗方案。比较两组的完全缓解率、总体缓解率以及不良反应情况。结果:R-CHOP组和CHOP组的完全缓解率相似(41.9%vs.37.5%,P=0.719),而总体缓解率前者要高于后者(83.8%vs.65.6%,P=0.096),但无显著性差异。治疗期间CHOP组有21.9%的患者疾病进展,而R-CHOP组仅为3.2%,两组有显著性差异(P=0.026)。R-CHOP组和CHOP组的不良反应发生率相似(65.6%vs.67.7%),差异无显著性(P=0.859)。最常见的不良反应均为白细胞下降;R-CHOP组其次常见不良反应是发热和寒战,可能与输注利妥昔单抗有关。两组的临床相关毒副作用相似,差异无显著性。结论:利妥昔单抗联合CHOP方案治疗CD20阳性的弥漫大B细胞型NHL与单纯CHOP方案相比,能显著降低治疗失败率,同时并不增加化疗的毒副反应。

Bcl-2 gene expression as a predictor of outcome in diffuse large B-cell lymphoma

Diffuse large B-cell lymphoma (DLBCL) is an aggressive lymphoma with a 5-year survival rate of 35%-60%. Various clinical factors included in the International Prognostic Index have failed to identify the patients with DLBCL who will not benefit from the standard R-CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone plus rituximab) treatment regimen. Bcl-2 has been implicated in conferring resistance to chemotherapy in non-Hodgkin's lymphoma and is therefore a candidate prognostic marker in DLBCL. To identify the correlation between Bcl-2 expression and response to rituximab-containing treatment regimens, histologic materials were analyzed from 292 elderly patients with confirmed DLBCL. Of these, 155 patients had received R-CHOP (53%) and 137 had received CHOP (47%). One hundred ninety-three patients (66%) were found to express high levels of Bcl-2 protein in > 50% of the tumor cells. Of the 193 Bcl-2-positive patients, the patients who received R-CHOP had a better 5-year overall rate than patients treated with CHOP (56% vs. 42%; P = 0.01), whereas in the patients with Bcl-2-negative disease, there was no statistically significant difference in the 5-year overall survival rates between the R-CHOP and CHOP regimens (58% vs. 52%; P = 0.6). Therefore, the addition of rituximab to the standard chemotherapy regimen seems to have overcome the Bcl-2-associated resistance to chemotherapy.

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.

Rituximab for HIV-associated lymphoma: weighing the benefits and risks

PURPOSE OF REVIEW: This review discusses the potential benefits and risks of using the anti-CD20 monoclonal antibody rituximab for the treatment of HIV-associated B-cell non-Hodgkin's lymphoma. RECENT FINDINGS: Studies have consistently demonstrated that rituximab improves response and survival when combined with standard chemotherapy compared with chemotherapy alone in immunocompetent patients with intermediate-grade non-Hodgkin's lymphoma. Several recently reported phase II and III trials have evaluated the use of rituximab plus chemotherapy for HIV-associated B-cell non-Hodgkin's lymphoma. Phase II trials combining rituximab with either standard cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy or infusional chemotherapy have reported encouraging results, suggesting a similar benefit in HIV-positive individuals. A phase III trial comparing CHOP with CHOP-plus rituximab (R-CHOP) demonstrated a lower risk from progression of the lymphoma, but a higher risk of early and late infectious-related death in patients with a low CD4 count (< 50/microL). SUMMARY: Rituximab should be used cautiously in patients with advanced HIV infection who have a CD4 count of less than 50/microL, as it seems to increase the risk of developing fatal infectious complications. In patients with higher CD4 counts, the benefit of rituximab may outweigh its risk, although this has yet to be confirmed in prospective, randomized trials specifically performed in this population.
