Bendamustine plus rituximab versus CHOP plus rituximab as first-line treatment for patients with indolent and mantle-cell lymphomas: an open-label, multicentre, randomised, phase 3 non-inferiority trial

BACKGROUND Rituximab plus chemotherapy, most often CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), is the first-line standard of care for patients with advanced indolent lymphoma, and for elderly patients with mantle-cell lymphoma. Bendamustine plus rituximab is effective for relapsed or refractory disease. We compared bendamustine plus rituximab with CHOP plus rituximab (R-CHOP) as first-line treatment for patients with indolent and mantle-cell lymphomas. METHODS We did a prospective, multicentre, randomised, open-label, non-inferiority trial at 81 centres in Germany between Sept 1, 2003, and Aug 31, 2008. Patients aged 18 years or older with a WHO performance status of 2 or less were eligible if they had newly diagnosed stage III or IV indolent or mantle-cell lymphoma. Patients were stratified by histological lymphoma subtype, then randomly assigned according to a prespecified randomisation list to receive either intravenous bendamustine (90 mg/m(2) on days 1 and 2 of a 4-week cycle) or CHOP (cycles every 3 weeks of cyclophosphamide 750 mg/m(2), doxorubicin 50 mg/m(2), and vincristine 1.4 mg/m(2) on day 1, and prednisone 100 mg/day for 5 days) for a maximum of six cycles. Patients in both groups received rituximab 375 mg/m(2) on day 1 of each cycle. Patients and treating physicians were not masked to treatment allocation. The primary endpoint was progression-free survival, with a non-inferiority margin of 10%. Analysis was per protocol. This study is registered with ClinicalTrials.gov, number NCT00991211, and the Federal Institute for Drugs and Medical Devices of Germany, BfArM 4021335. FINDINGS 274 patients were assigned to bendamustine plus rituximab (261 assessed) and 275 to R-CHOP (253 assessed). At median follow-up of 45 months (IQR 25-57), median progression-free survival was significantly longer in the bendamustine plus rituximab group than in the R-CHOP group (69.5 months [26.1 to not yet reached] vs 31.2 months [15.2-65.7]; hazard ratio 0.58, 95% CI 0.44-0.74; p<0.0001). Bendamustine plus rituximab was better tolerated than R-CHOP, with lower rates of alopecia (0 patients vs 245 (100%) of 245 patients who recieved ≥3 cycles; p<0.0001), haematological toxicity (77 [30%] vs 173 [68%]; p<0.0001), infections (96 [37%] vs 127 [50%]); p=0.0025), peripheral neuropathy (18 [7%] vs 73 [29%]; p<0.0001), and stomatitis (16 [6%] vs 47 [19%]; p<0.0001). Erythematous skin reactions were more common in patients in the bendamustine plus rituximab group than in those in the R-CHOP group (42 [16%] vs 23 [9%]; p=0.024). INTERPRETATION In patients with previously untreated indolent lymphoma, bendamustine plus rituximab can be considered as a preferred first-line treatment approach to R-CHOP because of increased progression-free survival and fewer toxic effects.

Bendamustine Plus Rituximab Is Effective and Has a Favorable Toxicity Profile in the Treatment of Mantle Cell and Low-Grade Non-Hodgkin's Lymphoma

PURPOSE The aim of this multicenter-study was to evaluate the progression-free survival, response rate and toxicity of the combination of bendamustine and rituximab (BR) in patients with mantle cell or low-grade lymphomas in first to third relapse or refractory to previous treatment. PATIENTS AND METHODS A total of 245 courses (median, four courses per patient) were administered to 63 patients. Bendamustine was given at a dose of 90 mg/m2 as a 30-minute infusion on days 1 and 2, combined with 375 mg/m2 rituximab on day 1, for a maximum of four cycles every 4 weeks. Histologies were 24 follicular, 16 mantle cell, 17 lymphoplasmacytoid, and six marginal zone lymphoma. RESULTS Fifty-seven of 63 patients responded to BR, corresponding to an overall response rate of 90% (95% CI, 80% to 96%) with a complete remission rate (CR) of 60% (95% CI, 47% to 72%). The median time of progression-free survival was 24 months (range, 5 to 44+ months), and the median duration of overall survival has not yet been reached. In mantle cell lymphomas, BR showed a considerable activity, achieving a response rate of 75% (95% CI, 48% to 93%) with a CR rate of 50%. Myelosuppression was the major toxicity, with 16% grade 3 and 4 leukocytopenia. Thrombocytopenia was rare, with only 3% grade 3 and 4. CONCLUSION These results demonstrate that the BR combination is a highly active regimen in the treatment of low-grade lymphomas and mantle cell lymphomas.

Bendamustine plus rituximab (B-R) versus CHOP plus rituximab (CHOP-R) as first-line treatment in patients with indolent and mantle cell lymphomas (MCL): Updated results from the StiL NHL1 study.

3 Background: This multicenter, randomized, phase III study compared B-R and CHOP-R as first-line treatment in indolent lymphoma and MCL and was presented at ASH 2009 including a comprehensive safety analysis. Here we present an updated analysis with a cut-off date for 31 Oct 2011. METHODS 549 patients (pts) with indolent or MCL were randomized to receive B-R or CHOP-R for a max of 6 cycles. The primary endpoint was PFS. RESULTS 514 pts randomized pts were evaluable (261 B-R; 253 CHOP-R). Patient characteristics were well balanced between arms; median age was 64 years. At a median follow-up of 45 months, PFS was significantly prolonged with B-R compared with CHOP-R (HR 0.58, 95% CI 0.44-0.74; P<0.001). Median PFS was 69.5 versus 31.2 months, respectively. The PFS benefit with B-R was maintained in all histological subtypes except marginal zone lymphoma. The PFS benefit with B-R was independent of age; HR 0.52 (P=0.002) in pts ≤60 years (n=199), and HR 0.62 (P=0.002) in pts >60 years (n=315). In pts with normal LDH (62%), PFS was significantly prolonged with B-R compared with CHOP-R (P<0.001), while in the elevated LDH group (38%) PFS was numerically, but not significantly increased with B-R compared with CHOP-R (P=0.118). In patients with follicular lymphoma, FLIPI subgroups defined by 0-2 factors (favorable) and 3-5 factors (unfavorable) had a longer PFS with B-R than with CHOP-R (P=0.043 and P=0.068 for the favorable and unfavorable FLIPI subgroups, respectively). Seventy four salvage treatments had been initiated in the B-R group; compared with 116 in the CHOP-R group, of those in the CHOP-R group 52 pts received B-R as salvage regimen. Overall survival did not differ between the treatment arms, with 43 and 45 deaths in the B-R and CHOP-R arms, respectively. Twenty secondary malignancies were observed in the B-R group compared with 23 in the CHOP-R group, with 1 hematological malignancy in each group (1 MDS in B-R, 1 AML in CHOP-R). CONCLUSIONS In patients with previously untreated indolent lymphoma, and elderly patients with MCL, B-R demonstrates a PFS benefit and improved tolerability compared with CHOP-R.

Positron Emission Tomography–Guided Therapy of Aggressive Non-Hodgkin Lymphomas (PETAL): A Multicenter, Randomized Phase III Trial

Purpose Interim positron emission tomography (PET) using the tracer, [18F]fluorodeoxyglucose, may predict outcomes in patients with aggressive non-Hodgkin lymphomas. We assessed whether PET can guide therapy in patients who are treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). Patients and Methods Newly diagnosed patients received two cycles of CHOP-plus rituximab (R-CHOP) in CD20-positive lymphomas-followed by a PET scan that was evaluated using the ΔSUVmax method. PET-positive patients were randomly assigned to receive six additional cycles of R-CHOP or six blocks of an intensive Burkitts lymphoma protocol. PET-negative patients with CD20-positive lymphomas were randomly assigned or allocated to receive four additional cycles of R-CHOP or the same treatment with two additional doses rituximab. The primary end point was event-free survival time as assessed by log-rank test. Results Interim PET was positive in 108 (12.5%) and negative in 754 (87.5%) of 862 patients treated, with statistically significant differences in event-free survival and overall survival. Among PET-positive patients, 52 were randomly assigned to R-CHOP and 56 to the Burkitt protocol, with 2-year event-free survival rates of 42.0% (95% CI, 28.2% to 55.2%) and 31.6% (95% CI, 19.3% to 44.6%), respectively (hazard ratio, 1.501 [95% CI, 0.896 to 2.514]; P = .1229). The Burkitt protocol produced significantly more toxicity. Of 754 PET-negative patients, 255 underwent random assignment (129 to R-CHOP and 126 to R-CHOP with additional rituximab). Event-free survival rates were 76.4% (95% CI, 68.0% to 82.8%) and 73.5% (95% CI, 64.8% to 80.4%), respectively (hazard ratio, 1.048 [95% CI, 0.684 to 1.606]; P = .8305). Outcome prediction by PET was independent of the International Prognostic Index. Results in diffuse large B-cell lymphoma were similar to those in the total group. Conclusion Interim PET predicted survival in patients with aggressive lymphomas treated with R-CHOP. PET-based treatment intensification did not improve outcome.

Prognostic value of circulating Bcl-2/IgH levels in patients with follicular lymphoma receiving first-line immunochemotherapy.

Bcl-2/IgH rearrangements can be quantified in follicular lymphoma (FL) from peripheral blood (PB) by polymerase chain reaction (PCR). The prognostic value of Bcl-2/IgH levels in FL remains controversial. We therefore prospectively studied PB Bcl-2/IgH levels from 173 first-line FL patients who were consecutively enrolled, randomized, and treated within the multicenter phase 3 clinical trial NHL1-2003 comparing bendamustine-rituximab (B-R) with rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone. From April 2005 to August 2008, 783 pre- and posttreatment PB samples were quantified by quantitative PCR. At inclusion, 114 patients (66%) tested positive and 59 (34%) were negative for Bcl-2/IgH. High pretreatment Bcl-2/IgH levels had an adverse effect on progression-free survival (PFS) compared with intermediate or low levels (high vs intermediate: hazard [HR], 4.28; 95% confidence interval [CI], 1.70-10.77; P = .002; high vs low: HR, 3.02; 95% CI, 1.55-5.86; P = .001). No PFS difference between treatment arms was observed in Bcl-2/IgH-positive patients. A positive posttreatment Bcl-2/IgH status was associated with shorter PFS (8.7 months vs not reached; HR, 3.15; 95% CI, 1.51-6.58; P = .002). By multivariate analysis, the pretreatment Bcl-2/IgH level was the strongest predictor for PFS. Our data suggest that pre- and posttreatment Bcl-2/IgH levels from PB have significant prognostic value for PFS in FL patients receiving first-line immunochemotherapy. This trial was registered at www.clinicaltrials.gov as #NCT00991211 and at the German Federal Institute for Drugs and Medical Devices as #BfArM-4021335.

[Intravascular lymphoma: two case reports demonstrating the heterogeneity of the disease].

Intravascular lymphoma (IVL) is a rare subtype of extranodal large-B-cell lymphoma, histologically characterized by accumulation of clonal lymphocytes in small vessels of different organs. Overall survival is usually poor. The clinical manifestations are highly variable, depending on the involved organs. Cutaneous and neurological involvement is frequent; the cutaneous symptoms are heterogeneous with erythema, erythematous papules and plaques, generalized telangiectases and lesions resembling panniculitis or Kaposi sarcoma. IVL may also be limited to the skin; this entity is included the current classifications. We present here two patients with two different variants of IVL. One showed only skin involvement with panniculitis-like induration and responded well to therapy with Rituximab-CHOP (Rituximab plus Cyclophosphamide, Doxorubicin, Vincristine, Prednisolone). The other patient had distinctive cutaneous and neurological symptoms which did not respond to therapy. By means of these two patients, we present the heterogeneity of IVL and discuss current aspects of diagnosis and treatment.
