Abstract High-dose chemotherapy (HD-CT) with autologous stem cell transplantation is considered to be the treatment of choice for relapsed high-grade non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL) patients, but the optimal treatment has not yet been defined. We evaluated a salvage treatment regimen consisting of conventional cycles with ifosfamide, etoposide, cytarabine, and dexamethasone (IVAD) followed by two cycles of HD-CT consisting of cyclophosphamide, melphalan, and etoposide (CMV) with autologous stem cell support in patients with relapsed or refractory NHL (n = 59) and HL (n = 16). Response to IVAD was complete remission (CR) in 16 patients (21%), partial remission (PR) in 39 patients (52%), stable disease (SD) in 18 patients (24%), and progressive disease (PD) in two patients (2.7%). Of 70 patients treated with HD-CT, 41 patients (59%) showed a CR, 20 patients a PR (29%), eight patients a SD (11%), and one patient a PD (1.4%). The 5-yr overall survival for the entire group of patients was 29%, and for patients with NHL and HL 25%, and 38%, respectively. The respective event-free survival probabilities at 5 yr were 22%, 16%, and 31%. Seven treatment-related deaths due to septicemia (three), cardiac arrhythmia (one), pneumonia (one), pneumonitis (one), and toxic epidermal necrolysis (one) were observed. In multivariate analysis, an International Prognostic Index of ,2 and resistant disease to first-line chemotherapy were poor independent prognostic factors for the subgroup of patients with NHL. In conclusion, these results indicate that IVAD/CMV is feasible as a salvage therapy for lymphoma patients. This treatment is currently evaluated with the addition of rituximab. [source]


Treatment of intermediate- and high-grade non-Hodgkin's lymphoma using CEOP versus CNOP

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 3 2002
A Hellenic Co-operative Oncology Group Study
Abstract:Introduction: During the last few years epirubicin (E) and mitoxantrone (M) (Novantrone) have been used in the treatment of non-Hodgkin's lymphoma (NHL), because of their favorable principal profile. In particular, M has less severe non-hematological toxicity. Patients and methods: A randomized multicenter phase III study was conducted in order to compare the efficacy and toxicity of CEOP and CNOP in intermediate- and high-grade NHL. CEOP (arm A) consisted of cyclophosphamide 1000 mg m,2, vincristine 2 mg, E 70 mg m,2 on day 1 and prednisone 60 mg on days 1,7. The CNOP regimen (arm B) was identical to CEOP except for replacement of E by M at a dose of 12 mg m,2. Randomization was stratified according to stages I,IV. From September 1993 to March 1999, 249 patients registered for the trial. Patient characteristics were equally distributed in the two arms, except for age and International Prognostic Index (IPI) groups. Results: There were no significant differences between the two groups in the rates of complete (CR) and partial response (PR). The overall response rate was 78% in arm A (57% CR, 21% PR) and 82% in arm B (60% CR, 22% PR). With a median follow-up time of 47.3 months, the median survival was not reached in arm A, while it was 39.5 months in arm B (P = 0.09). Three-year survival rates were 62.5% for CEOP and 51.5% for CNOP. There was no significant difference regarding the time to progression between the two groups (29.7 vs. 18.5 months); furthermore the median duration of CRs was 71.6 and 49 months for CEOP and CNOP, respectively (P = 0.07). The therapeutic efficacies of both regimens were equivalent among the four IPI groups. More alopecia was observed in arm A. WHO grade >2 neutropenia was more frequent in arm B. Supportive treatment with G-CSF was given to 22 and 24 patients, respectively. Conclusion: There were no significant differences in terms of overall response rates, overall survival and time to progression between CEOP and CNOP in the treatment of intermediate- and high-grade NHL. Patients with low or low intermediate IPI risk treated with either CEOP or CNOP showed significantly better survival, response rates and time to progression than those with high intermediate or high IPI risk. Therefore, new improved therapeutic approaches should be developed for the treatment of high IPI risk patients. [source]


Pyothorax-associated lymphoma (PAL): a western case with marked angiocentricity and review of the literature

Aims :,To report a case of pyothorax-associated lymphoma in a non-immunocompromised 78-year-old man with a 45-year history of tuberculous pleuritis and left pleural effusion. Pyothorax-associated lymphoma is a high-grade non-Hodgkin's lymphoma occurring in 2% of patients with long-standing tuberculous pleuritis and pyothorax. Pyothorax-associated lymphoma is frequently Epstein,Barr virus (EBV)-associated, mainly reported in Japan but exceedingly rare in western countries. Methods and results :,Histology revealed a high-grade, diffuse large B-cell lymphoma with immunoblastic and plasmacytoid features and marked angiocentricity with focal destruction of the vessel walls. Immunohistochemistry revealed a post germinal B-cell phenotype. RNA in-situ hybridization and molecular analysis showed a latent EBV infection and absence of human herpes virus-8 (HHV-8). Conclusions :,Pyothorax-associated lymphoma represents a rare but distinctive type of diffuse large B-cell lymphoma, with characteristic clinico-epidemiological, immunohistological, and biological features.

Development of anti-VWF antibody in a patient with severe haemophilia A following the development of high-grade non-Hodgkin's lymphoma

INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 3 2002

A 9-year-old-boy with severe haemophilia A (factor VIII < 1%) developed colicky abdominal pain with swelling in the left iliac fossa for 4 weeks. His LDH level was 1423 IU/l (normal range < 220 IU/l) and his uric acid, 6.8 mg/dl. A computerised tomography (CT) scan of the abdomen demonstrated a tumour of the terminal ileum and mild hepatosplenomegaly. Pre-operative screening for factor VIII inhibitor was negative. Post-operatively, the patient needed high doses of factor VIII to maintain haemostasis. The tumour was found to be a high-grade lymphoma of Burkitt's type. He recovered from his operation and chemotherapy was commenced. Investigations demonstrated an anti-von Willebrand factor (VWF) antibody. He subsequently relapsed and died of progressive disease. Development of anti-VWF antibody in lymphoma is well known, but development of this antibody in a haemophilia A patient developing lymphoma has not been reported. The present case shows that antibody to VWF should be considered as a possible reason for an increased factor VIII requirement in such patients. [source]


Long-term survival with favorable cognitive outcome after chemotherapy in primary central nervous system lymphoma

Objective To evaluate long-term progression-free survival and overall survival, quality of life, and cognitive function in primary central nervous system lymphoma after systemic and intraventricular chemotherapy without radiotherapy. Methods A long-term follow-up was conducted on surviving primary central nervous system lymphoma patients having been enrolled in a pilot/phase II trial between September 1995 and December 2001. Initially, 65 patients (median age, 62 years) had been treated with systemic and intraventricular chemotherapy without radiotherapy. All living patients were contacted, and a neurological examination, comprehensive neuropsychological testing, quality-of-life assessment, and imaging were performed. Results Twenty-one of all 65 patients (32 %) and 17 of 30 patients 60 years or younger (57%), respectively, were still alive at median follow-up of 100 months (range, 77,149 months). Nineteen of 21 patients completed all investigations; 1 was lost to follow-up. In three patients, an exclusively extraneural relapse of a high-grade non-Hodgkin's lymphoma was diagnosed after 9, 31, and 40 months, respectively. All of them experienced complete remission to high dose. Neither late neurotoxicity nor compromise of quality of life was found in any of the patients examined. Interpretation Primary polychemotherapy based on high-dose methotrexate (MTX) and cytarabine (Ara-C) is highly efficient in treatment of primary central nervous system lymphoma. About half of patients 60 years or younger can obviously be cured with this regimen without long-term neurotoxic sequelae or quality-of-life compromise. ANN NEUROL 2010;67:182,189 [source]
