Abstract (Expand)

BACKGROUND: T-cell lymphomas (T-NHL) generally carry a poor prognosis. High-dose therapy (HDT) and autologous stem cell transplantation (ASCT) are increasingly used to treat younger patients. DESIGN … AND METHODS: We treated patients <61 years with high-risk aggressive lymphoma with four to six courses of dose-escalated CHOP plus etoposide (MegaCHOEP) necessitating repeated ASCT. Outcomes of patients with mature T-NHL (excluding anaplastic lymphoma kinase-positive anaplastic large cell lymphoma) and aggressive B-NHL were compared using multivariate Cox regression analysis. RESULTS: Compared with 84.4% of B-NHL patients, 66.7% of T-NHL patients were able to receive all treatments; the rates of progressive disease were 27.3% in T-NHL and 16.3% in B-NHL patients. At 3 years, event-free survival (EFS) and overall survival were significantly worse for T-NHL [25.9% confidence interval (CI) 10.4% to 41.4% and 44.5% CI 26.5% to 62.5%) than for B-NHL patients (60.1% CI 52.1% to 68.1%; P < 0.001 and 63.4% CI 55.4% to 71.4%; P = 0.016). In multivariate analysis, T-NHL was a strongly significant adverse risk factor for EFS (relative risk 2.2, P = 0.001). CONCLUSIONS: MegaCHOEP for T-NHL patients was no better than other high-dose regimens and was unable to address the major problems of HDT/ASCT: neither early progressions nor early relapses were reduced. This study sheds some doubt on expectations that HDT/ASCT will significantly improve outcomes for patients with T-NHL.

Favorable impact of the interleukin-4 receptor allelic variant I75 on the survival of diffuse large B-cell lymphoma patients demonstrated in a large prospective clinical trial.

Abstract (Expand)

BACKGROUND: Recently published data indicate that host germline variations in immune genes can influence the outcome of lymphoma patients. Interleukin (IL)-4 and IL13 are crucial immune factors and may … influence the course of the disease. Both cytokines signal through the interleukin-4 receptor (IL4R). Therefore, we investigated whether polymorphisms of IL4, IL13 and IL4R genes could predict the outcome of diffuse large B-cell lymphoma (DLBCL) patients. METHODS: In 228 DLBCL samples of the German High-Grade Non-Hodgkin's Lymphoma Study Group, the polymorphisms of IL4 (-524CT, rs2243250), IL13 (-1069CT, rs1800925) and IL4R (I75V, rs1805010; S503P, rs1805015; Q576R, rs1801275) were analyzed and the soluble interleukin-4 receptor (sIL4R) serum level was measured before the start of chemotherapy. RESULTS: Patients harboring IL4R V75 (IL4R(I75V-AG) and IL4R(I75V-GG)) had shorter overall survival (OS) (P = 0.044) and event-free survival (EFS) (P = 0.056) periods compared with I75 carriers (IL4R(I75V-AA)). Multivariate analysis adjusted to the International Prognostic Index revealed a relative risk of 1.9 for carriers of the IL4R V75 (P = 0.011) in relation to OS. DLBCL patients homozygous for the IL4R I75 and low sIL4R serum levels have the most favorable OS and EFS. CONCLUSIONS: These data support the role for host germline gene variations of immunologically important factors like the IL4R I75V gene variation to predict the survival in DLBCL patients.

CNS events in elderly patients with aggressive lymphoma treated with modern chemotherapy (CHOP-14) with or without rituximab: an analysis of patients treated in the RICOVER-60 trial of the German High-Grade Non-Hodgkin Lymphoma Study Group (DSHNHL).

Abstract (Expand)

One thousand two hundred twenty-two patients treated in the Rituximab with CHOP over age 60 years (RICOVER-60) trial were examined for central nervous system (CNS) disease developing during first-line … therapy or after a complete or partial remission had been achieved. Patients received 6 or 8 courses of CHOP (cyclophosphamide, adriamycin, vincristine, prednisone) administered every 2 weeks (CHOP-14) with or without rituximab. CNS prophylaxis for patients with involvement of bone marrow, testes, upper neck, or head consisted of intrathecal (i.th.) methotrexate (days 1 and 5 of first 2 courses). Fifty-eight cases of lymphoma in the CNS were observed (36/609 patients in the CHOP-14 and 22/608 patients in the arituximab-CHOP-14 [R-CHOP-14] arm). The estimated 2-year incidence of CNS disease was 6.9% (confidence interval [CI] 4.5; 9.3) after CHOP-14 and 4.1% (CI 2.3; 5.9) after R-CHOP-14. R-CHOP reduced the relative risk for CNS disease to 0.58 (95% CI 0.3; 1.0, P = .046). Cox regression analysis identified "involvement of more than 1 extranodal site" and "B-symptoms" as significant risk factors for CNS disease. Patients treated with R-CHOP-14 did not show any benefit from i.th. methotrexate. We conclude that elderly patients with aggressive CD20-positive lymphoma show a significantly lower incidence of CNS disease if treated with R-CHOP-14 instead of CHOP-14. Intrathecal methotrexate has no role in preventing CNS disease for patients treated with combined immunochemotherapy (R-CHOP-14)--with the possible exception of patients with testicular involvement.
