Prognostic Values of Various Clinical Factors and GeneticSubtypes for Diffuse Large B-cell lymphoma Patients: ARetrospective Analysis of 227 Cases

Aim: To analyze the significance of different clinical factors for prognostic prediction in diffuse large B-celllymphoma (DLBCL) patients. Methods: Two hundred and twenty-seven DLBCL patients were retrospectivelyreviewed. Patients were managed with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)regimen or rituximab plus the CHOP (RCHOP) regimen. Results: Lactate dehydrogenase (LDH), β2-microglobulin (β2-M), B symptoms, Ann Arbor stage and genetic subtypes were statistically relevant in predictingthe prognosis of the overall survival (OS). In the CHOP group, the OS in patients with germinal center B-celllike(GCB)(76.2%) was significantly higher than that of the non-GCB group (51.9%, P=0.032). With RCHOPmanagement, there was no statistical difference in OS between the GCB (88.4%) and non-GCB groups (81.9%,P=0.288). Conclusion: Elevated LDH and β2-M levels, positive B symptoms, Ann Arbor stage III/IV, and primarynodal lymphoma indicate an unfavorable prognosis of DLBCL patients. Patients with GCB-like DLBCL have abetter prognosis than those with non-GCB when treated with the CHOP regimen. The RCHOP treatment withthe addition of rituximab can improve the prognosis of patients with DLBCL.     

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.     

International prognostic index-based outcomes for diffuse large B-cell lymphomas

BACKGROUND: We present the results of doxorubicin-based chemotherapy with or without involved-field radiotherapy for patients with diffuse large B-cell lymphoma (DLBCL) according to the international prognostic index (IPI). METHODS: From September 1988 through December 1996, 294 patients with Stage I-IV Working Formulation large B-cell or T-cell lymphomas were treated prospectively on two protocols at our center. Diagnoses were reclassified subsequently according to the new World Health Organization classification. Two-hundred and twenty-four patients had DLBCL, including 24 patients with primary mediastinal large B-cell lymphoma. Treatment consisted of a median of six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy with or without involved-field radiotherapy (median dose, 39.6 Gy). RESULTS/CONCLUSIONS: The median length of follow-up among surviving patients was 5.0 years. Patient subgroups differed from each other in terms of progression-free (P = 0.003), cause-specific (P = 0.003), and overall (P = 0.001) survival rates when analyzed by IPI. Five-year progression-free, cause-specific, and overall survival rates for 212 patients with an IPI of 0-2 were 73%, 84%, and 82%, respectively, versus only 37%, 33%, and 32% for 12 patients with an IPI of 3-4. To improve our results, we are conducting clinical trials with young DLBCL patients and with patients who are older than 60 years. The young DLBCL patients, who have more than two adverse prognostic features, are receiving high-dose chemotherapy and autologous stem cell rescue. The patients who are older than 60 years, regardless of IPI, are receiving rituximab immunotherapy and liposomal CHOP chemotherapy with or without involved-field radiotherapy.

Impact on survival of addition of etoposide to primary chemotherapy in diffuse large B‐cell lymphoma: a Swedish Lymphoma Registry study

No randomised study in the rituximab era has been performed specifically to evaluate addition of etoposide to treatment of diffuse large B‐cell lymphoma (DLBCL). The aim of this study was to compare the outcome with three chemotherapy regimens (R‐CHOP‐21, R‐CHOP‐14 and R‐CHOEP‐14) in a population‐based cohort in terms of overall survival, adjusted for clinical prognostic factors. Through the Swedish Lymphoma Registry, 3443 patients with DLBCL were identified 2007–2012. Among all patients, there was no evidence of a difference between the regimens, after adjustment for prognostic factors. However, when restricted to patients aged up to 65, R‐CHOEP‐14 was associated with superior outcome compared to both R‐CHOP‐21 (hazard ratio: 0.49, 95% confidence interval: 0.3–0.9, p = 0.028) and R‐CHOP‐14 (hazard ratio: 0.64, 95% confidence interval: 0.4–1.0, p = 0.06), when adjusted for prognostic factors. Results were consistent in an additional stratified analysis with patients grouped according to age and IPI‐score. In conclusion, we could show that R‐CHOEP‐14 was associated with superior overall survival in patients with DLBCL aged up to 65 years, indicating that this may be a valid treatment option for this patient population. To further investigate which patient groups that may benefit the most from treatment intensification, R‐CHOEP‐14 should be compared to R‐CHOP‐21 in a randomised setting.

弥漫性大B细胞淋巴瘤诊治进展

弥漫性大B细胞淋巴瘤(DLBCL)是目前最常见的成人非霍奇金淋巴瘤,不同亚型在临床表现、遗传学以及分子生物学等特征方面存在明显差异,所观察到的遗传学改变主要集中在BCL6,BCL2,cMYC,FAS(CD95)的突变和体细胞超突变的异常上。虽然CHOP方案化疗能够治愈部分DLBCL,但完全缓解率仅为45%~55%。强化化疗方案或干细胞移植可改善某些患者的长期生存,最突出和一致改善弥漫性大B细胞淋巴瘤的长期生存效果则是随着抗CD20单克隆抗体药物与化疗的联合应用。     

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.     

Cost utility in the United States of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone for the treatment of elderly patients with diffuse large B-cell lymphoma

BACKGROUND: Findings from the Groupe d'Etude des Lymphomes Adultes LNH 98-5 study showed that rituximab added to combined cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) prolonged progression-free survival and overall survival in adults age >/= 60 years with diffuse large B-cell non-Hodgkin lymphoma (DLBCL). The current study was conducted to investigate the incremental cost utility of the addition of rituximab to CHOP (R-CHOP) compared with CHOP alone. METHODS: Clinical prognosis of the time to disease progression and death was estimated using published evidence from the LNH 98-5 study (n = 399 patients) that was linked mathematically to published long-term outcome data on patients with DLBCL. Drug-acquisition costs were based on published data from formulary pricing sources, and the costs of cancer surveillance and end-of-life care were based on published literature sources. The authors assessed cost utility as the difference in costs between R-CHOP and CHOP divided by the increase in expected overall survival adjusted for quality of life. RESULTS: Over 5 years, it was projected that R-CHOP would prolong overall survival by 1.04 years. The mean cumulative cost of CHOP was 3358 dollars, and the mean cost of R-CHOP was 17,225 dollars, resulting in a cumulative net increase of 13,867 dollars. The posttreatment cancer surveillance cost for CHOP was 3950 dollars, compared with 5202 dollars for R-CHOP. It was estimated that R-CHOP would have a cost-utility ratio of 19,297 dollars per year of life gained compared with CHOP when adjusted for quality of life. R-CHOP remained cost effective over wide ranges of variables in sensitivity analyses. CONCLUSIONS: Compared with CHOP alone, it was predicted that R-CHOP would be cost effective in elderly patients with DLBCL.
