Background: Most peripheral T-cell lymphoma (PTCL) patients have a poor outcome and the identification of prognostic factors at diagnosis is needed. Patients and methods: The prognostic impact of total metabolic tumor volume (TMTV0), measured on baseline [18F] 2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography, was evaluated in a retrospective study including 108 PTCL patients (27 PTCL not otherwise specified, 43 angioimmunoblastic T-cell lymphomas and 38 anaplastic large-cell lymphomas). All received anthracycline-based chemotherapy. TMTV0 was computed with the 41% maximum standardized uptake value threshold method and an optimal cut-off point for binary outcomes was determined and compared with others prognostic factors. Results: With a median follow-up of 23 months, 2-year progression-free survival (PFS) was 49% and 2-year overall survival (OS) was 67%. High TMTV0 was significantly associated with a worse prognosis. At 2 years, PFS was 26% in patients with a high TMTV0 (>230 cm3, n = 53) versus 71% for those with a low TMTV0, [P < 0.0001, hazard ratio (HR) = 4], whereas OS was 50% versus 80%, respectively, (P = 0.0005, HR = 3.1). In multivariate analysis, TMTV0 was the only significant independent parameter for both PFS and OS. TMTV0, combined with PIT, discriminated even better than TMTV0 alone, patients with an adverse outcome (TMTV0 >230 cm3 and PIT >1, n = 33,) from those with good prognosis (TMTV0 ≤230 cm3 and PIT ≤1, n = 40): 19% versus 73% 2-year PFS (P < 0.0001) and 43% versus 81% 2-year OS, respectively (P = 0.0002). Thirty-one patients (other TMTV0–PIT combinations) had an intermediate outcome, 50% 2-year PFS and 68% 2-year OS. Conclusion: TMTV0 appears as an independent predictor of PTCL outcome. Combined with PIT, it could identify different risk categories at diagnosis and warrants further validation as a prognostic marker. [less ▲]

Background The superiority of a chemotherapy with doxorubicin, cyclophosphamide, vindesine, bleomycin and prednisone (ACVBP) in comparaison with cyclophosphamide, doxorubicin, vincristin and prednisone plus radiotherapy for Young patients with localized diffuse large B-cell lymphoma (DLBCL) was previously demonstrated. We report the results of a trial which évaluâtes the role of rituximab combined with ACVBP (R- ACVBP) in these patients. Patients and methods untreated patients younger than 66 years with stage I or II DLBCL and no adverse prognostic factors of the age-adjusted International Prognostic Index were randomly assigned to receive three cycles of ACVBP plus sequential consolidation with or without the addition of four infusions of rituximab. Results a total of 223 patients were randomly allocated to the study, 110 in the R-ACVBP group and 113 in the ACVBP group. After a median follow-up of 43 months, our 3-year estimate of event-free survival was 93% in the R-ACVBP group and 82% in the ACVBP group (P=0.0487). Three-year estimate of progression-free survival was increased in the R-ACVBP group (95% versus 83%, P=0.0205). Overall survival did not differ between the two groups with a 3-year estimâtes of 98% and 97%, respectively (P=0.686). Conclusion in Young patients with low-risk localized DLBCL, rituximab combined with three cycles of ACVBP plus consolidation is significantly Superior to ACVBP plus consolidation alone. [less ▲]

Background Diffuse large B-cell lymphomas (DLBCLs) arising in specific extranodal sites have peculiar clinicopathologic features. Patients and methods We analyzed a cohort of 187 primary Waldeyer's ring (WR) DLBCLs retrieved from GELA protocols using anthracyclin-based polychemotherapy. Results Most patients (92%) had stage I–II disease. A germinal center B-cell-like (GCB) immunophenotype was observed in 61%, and BCL2 expression in 55%, of WR DLBCLs. BCL2, BCL6, IRF4 and MYC breakpoints were observed in, respectively, 3 of 42 (7%), 9 of 36 (25%), 2 of 26 (8%) and 4 of 40 (10%) contributive cases. A variable follicular pattern was evidenced in 30 of 68 (44%) large biopsy specimens. The 5-year progression-free survival (PFS) and the overall survival (OS) of 153 WR DLBCL patients with survival information were 69.5% and 77.8%, respectively. The GCB immunophenotype correlated with a better OS (P = 0.0015), while BCL2 expression predicted a worse OS (P = 0.037), an effect overcome by the GCB/non-GCB classification. Compared with matched nodal DLBCLs, WR DLBCLs with no age-adjusted international prognostic index factor disclosed a better 5-year PFS rate (77.5% versus 70.7%; P = 0.03). Conclusions WR DLBCLs display distinct clinicopathologic features compared with conventional DLBCLs, with usual localized-stage disease, common follicular features and a high frequency of GCB immunophenotype contrasting with a low rate of BCL2 rearrangements. In addition, they seem to be associated with a better outcome than their nodal counterpart. [less ▲]

Purpose Chemoradiotherapy has been considered standard treatment for patients with limited-stage aggressive lymphoma on the basis of trials conducted before the introduction of the International Prognostic Index. To evaluate this approach in elderly patients with low-risk localized lymphoma, we conducted a trial comparing chemoradiotherapy with chemotherapy alone. Patients and Methods Previously untreated patients older than 60 years with localized stage I or II histologically aggressive lymphoma and no adverse prognostic factors of the International Prognostic Index were randomly assigned to receive either four cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus involved-field radiotherapy (299 patients) or chemotherapy alone with four cycles of CHOP (277 patients). Results With a median follow-up time of 7 years, event-free and overall survival did not differ between the two treatment groups (P =.6 and P =.5, respectively). The 5-year estimates of event-free survival were 61% for patients receiving chemotherapy alone and 64% for patients receiving CHOP plus radiotherapy; the 5-year estimates of overall survival were 72% and 68%, respectively. In a multivariate analysis, overall survival was affected by stage II disease (P <.001) and male sex (P =.03). Conclusion In this large prospective study, CHOP plus radiotherapy did not provide any advantage over CHOP alone for the treatment of low-risk localized aggressive lymphoma in elderly patients.

Purpose: Randomized trial LNH93-3 was conducted on patients who had poor-prognosis aggressive lymphoma and were younger than 60 years with two to three factors of the age-adjusted International Prognostic Index to evaluate the benefit of early high-dose therapy (HDT) with autologous stem-cell transplantation (ASCT). Patients and Methods: Patients were randomized between doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone (ACVBP) chemotherapy followed by sequential consolidation and an experimental shortened treatment consisting of three cycles with escalated doses of cyclophosphamide, epirubicin, vindesine, bleomycin, and prednisone and collection of peripheral-blood stem cells. On day 60, HDT was administered with 1,3-bis(2-chloroethyl)-1-nitrosourea, etoposide, cytarabine, and melphalan followed by ASCT. Results: Eligible patients (n = 370) with aggressive lymphoma were analyzed. For ACVBP (181 patients) and HDT (189 patients), respective complete remission rates were 64% and 63%. With a median follow-up of 60 months, 5-year overall survival and event-free survival for ACVBP and HDT were 60% +/- 8% and 46% +/- 8% (P = .007) and 52 +/- 8% and 39 8% (P = .01), respectively. Survival was independently affected by age greater than 40 years (P = .0003), T-cell phenotype (P = .009), bone marrow involvement (P = .003), and HDT treatment group (P = .04). Conclusion: Early HDT with ASCT in high-risk patients was inferior to the ACVBP chemotherapy regimen. These results indicate that the received dose-intensity before HDT was too low when compared with ACVBP and HDT and was given too early. (C) 2002 by American Society of Clinical Oncology. [less ▲]
