Statin-independent prognosis of patients with diffuse large B-cell lymphoma receiving rituximab plus CHOP therapy

BackgroundA recent laboratory study indicated that statins impaired the antitumor effects of rituximab by inducing conformational changes in CD20. Although these findings raised significant concerns about statin use during rituximab treatment, their clinical significance is unclear.Patients and methodsWe conducted a retrospective study investigating the effects of statins on the prognosis of diffuse large B-cell lymphoma (DLBCL) treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP). Newly diagnosed DLBCL patients were analyzed (n = 256), including 35 patients taking statins.ResultsThe 3-year progression-free survival rates were 84% and 73% (P = 0.38), while the overall survival rates were 89% and 78% (P = 0.28) for those patients treated with and without statins, respectively. After adjusting for the International Prognostic Index and serum cholesterol level, statin use was not associated with prognosis.ConclusionsThese results indicate that statins do not influence the clinical prognosis of DLBCL treated with RCHOP. Further studies with larger numbers of patients are warranted to confirm the prognostic significance of statins for patients with DLBCL receiving rituximab-containing chemotherapy.

Introduction of combined CHOP plus rituximab therapy dramatically improved outcome of diffuse large B-cell lymphoma in British Columbia.

PURPOSE: For more than two decades, cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) has been the standard therapy for diffuse large B-cell lymphoma (DLBCL). The addition of rituximab to CHOP has been shown to improve outcome in elderly patients with DLBCL. We conducted a population-based analysis to assess the impact of this combination therapy on adult patients with DLBCL in the province of British Columbia (BC). METHODS: We compared outcomes during a 3-year period; 18 months before (prerituximab) and 18 months after (postrituximab) institution of a policy recommending the combination of CHOP and rituximab for all patients with newly diagnosed advanced-stage (stage III or IV or stage I or II with "B" symptoms or bulky [> 10 cm] disease) DLBCL. RESULTS: A total of 292 patients were evaluated; 140 in the prerituximab group (median follow-up, 42 months) and 152 in the postrituximab group (median follow-up, 24 months). Both progression-free survival (risk ratio, 0.56; 95% CI, 0.39 to 0.81; P = .002) and overall survival (risk ratio, 0.40; 95% CI, 0.27 to 0.61, P < .0001) were significantly improved in the postrituximab group. After controlling for age and International Prognostic Index score, era of treatment remained a strong independent predictor of progression-free survival (risk ratio, 0.59; 95% CI, 0.41 to 0.85; P = .005) and overall survival (risk ratio, 0.43; 95% CI, 0.29 to 0.66; P < .001). The benefit of treatment in the postrituximab era was present regardless of age. CONCLUSION: The addition of rituximab to CHOP chemotherapy has resulted in a dramatic improvement in outcome for DLBCL patients of all ages in the province of BC.     

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.     

Addition of rituximab to reduced-dose CHOP chemotherapy is feasible for elderly patients with diffuse large B-cell lymphoma

Purpose

Evolution of R-CHOP therapy for older patients with diffuse large B-cell lymphoma

Non-Hodgkin’s lymphoma is the fifth most common malignancy in adults in the USA. This disorder is especially relevant in the elderly patient population, as the median age of patients with this disorder is 65 years. Almost half of these disorders in older patients are of a diffuse large B-cell (DLBCL) subtype. The therapy of DLBCL has undergone a renaissance in the past decade, with the addition of rituximab to standard regimens, such as cyclophosphamide– doxorubicin–vincristine–prednisone (CHOP). Over this time, there have been several large Phase III treatment trials in which the CHOP and rituximab-CHOP (R-CHOP) regimens have been prospectively compared, including three trials confined to the elderly patient population. In these trials, it has been demonstrated repeatedly that the addition of rituximab results in an improved outcome, with higher response rates and prolongation in parameters including progression-free, event-free, disease-free and overall survival. In addition, this regimen has been well tolerated, even in older patients. Based upon these data, the R-CHOP regimen has now been established as the standard for initial therapy of DLBCL in older patients with DLBCL. However, issues still remain with regard to the ideal schedule of R-CHOP administration, specifically the optimal number of cycles of therapy (six vs eight), as well as cycle length (14 vs 21 days).

Soluble interleukin-2 receptor retains prognostic value in patients with diffuse large B-cell lymphoma receiving rituximab plus CHOP (RCHOP) therapy

Background: Soluble interleukin-2 receptor (SIL-2R) is knownto be a prognostic parameter in patients with diffuse largeB-cell lymphoma (DLBCL) receiving cyclophosphamide, doxorubicin,vincristine and prednisone (CHOP) therapy. However, its prognosticvalue has not been well known since the introduction of rituximab. Patients and methods: We retrospectively evaluated the prognosticimpact of SIL-2R in 228 DLBCL patients, comparing 141 rituximab-combinedCHOP (RCHOP)-treated patients with 87 CHOP-treated patientsas a historical control. Results: Patients with high serum SIL-2R showed significantlypoorer event-free survival (EFS) and overall survival (OS) thanpatients with low SIL-2R in both the RCHOP group (2-year EFS,66% versus 92%, P < 0.001; OS, 82% versus 95%, P = 0.005)and the CHOP group (2-year EFS, 40% versus 82%; OS, 61% versus90%, both P < 0.001). Multivariate analysis including thefive parameters of International Prognostic Index (IPI) andtwo-categorized IPI revealed that SIL-2R was an independentprognostic factor for EFS and OS in the RCHOP group as wellas in the CHOP group. Conclusions: Our results demonstrate that SIL-2R retains itsprognostic value in the rituximab era. The prognostic valueof SIL-2R in DLBCL patients receiving rituximab-combined chemotherapyshould be reassessed on a larger scale and by long-term follow-up.

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。     

Conditional survival of patients with diffuse large B-cell lymphoma

BACKGROUND: Prognosis of lymphoma patients is usually estimated at the time of diagnosis and the estimates are guided by the International Prognostic Index (IPI). However, conditional survival estimates are more informative clinically, as they consider those patients only who have already survived a period of time after treatment. Conditional survival data have not been reported for lymphoma patients. METHODS: Conditional survival was estimated for 1209 patients with diffuse large B-cell lymphoma (DLBCL) from the population-based LYFO registry of the Danish Lymphoma Group. The Kaplan-Meier method was used to estimate conditional survival at 0-5 years after diagnosis. RESULTS: The probability of surviving 5 years increases with each year survived for the first 3 years after diagnosis, after which the increase is minimal. The median survival increases from 38 months for all patients to between 108 and 120 months, conditioned on survival for at least 3-5 years. The prognostic capacity of the IPI and the age-adjusted IPI was high at diagnosis, but the significance gradually declined in the first years after diagnosis. Furthermore, the prognostic impact of the individual clinical variables of the IPI was also significant at diagnosis, but 2 years after diagnosis only age had prognostic impact. Multivariate analysis of patients who survived > or = 3 years identified only age as a prognostic factor. CONCLUSION: For patients with DLBCL who have survived more than 1 year after diagnosis, the conditional survival probability provides more accurate prognostic information than the conventional survival rate estimated from the time of diagnosis.     

Prognostic factors for diffuse large B-cell lymphoma in the R(X)CHOP era

BackgroundThe introduction of rituximab (R) to conventional CHOP chemotherapy for newly diagnosed diffuse large B-cell lymphoma (DLBCL) led to an unequivocal improvement in survival, establishing RCHOP as the standard of care. Still, nearly 40% of DLBCL patients will eventually die of relapsed disease. Efforts to improve outcomes by addition of new biologic agents (X) to the RCHOP backbone are underway. In this era of R(X)CHOP, it is imperative to develop prognostic and predictive markers, not only to identify patients who will suffer a particularly aggressive course, but also to accurately select patients for clinical trials from which they will most benefit.DesignThe following review was undertaken to describe prognostic factors in DLBCL, with emphasis on markers that are accurate, relatively available, and clinically applicable in 2014.ResultsThe International Prognostic Index retains its validity in the era of RCHOP, although with limited ability to predict those with <50% chance of long-term survival. Gene expression profiling has provided novel insights into the biology of DLBCL and led to the development of immunohistochemistry (IHC) algorithms that are in routine practice. Identification of a ‘double-hit’ (DH) lymphoma by fluorescent in situ hybridization with aberrations involving MYC and/or BCL2 and BCL6 genes has important implications due to its extremely dismal prognosis with RCHOP. Other markers such as the absolute lymphocyte count (ALC), serum immunoglobulin free light chains, vitamin D levels, serum cytokines/chemokines, and imaging with positron emission tomography (PET) have all shown promise as future predictive/prognostic tests.ConclusionsThe future for new treatment options in DLBCL is promising with current clinical trials testing novel targeted agents such as bortezomib, lenalidomide, and ibrutinib as the ‘X’ in R(X)CHOP. Predictive factors are required to select and randomize patients appropriately for these trials. We envision the day when ‘X’ will be chosen based on the biological characteristics of the tumor.

A case of neurotoxicity reduced with pregabalin in R-CHOP chemotherapy for diffuse large B-cell lymphoma

When performing R-CHOP(rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone)for diffuse large B-cell lymphoma(DLBCL), neurotoxicity of vincristine(VCR)is the serious dose-limiting factor.Pregabalin is one of the first-line treatments for painful diabetic peripheral neuropathy in many countries, and we have administered it to relieve the neurotoxicity associated with adverse effects of VCR in a DLBCL patient treated with the R-CHOP regimen.A 49-year-old man with kidney DLBCL had surgery performed.Afterward, the R-CHOP regimen was introduced.In order to relieve the neurotoxicity of VCR, pregabalin was used from day 8 in the second course.The severity of sensory neurotoxicity after the administration of pregabalin was improved from CTCAE(v4.0)grade 3 to grade 1.Therefore, there is a possibility that VCR-induced neurotoxicity is relieved by pregabalin.Further trials are needed to confirm the value of pregabalin.
