High-dose therapy with autologous transplantation for aggressive non-Hodgkin's lymphoma: the Bologna experience.

Patients with aggressive non-Hodgkin's lymphoma (NHL) who relapse after initial therapy have a poor prognosis and with standard dose salvage therapy the outlook remains poor. In this work we examine the patient characteristics and outcome of patients with aggressive NHL treated with HDT and autologous transplantation at our Institute from 1982 to 1999. A retrospective analysis was performed examining patient characteristics, prior chemotherapy regimens, pretransplant disease status, HDT regimen, source of stem cells, time for hematopietic recovery, complications of transplantation, response rates, overall survival (OS) and relapse-free survival (RFS).

Clinical experience with fludarabine in indolent non-Hodgkin's lymphoma.

Fludarabine, a purine nucleoside analog, is currently indicated for the first-line treatment of chronic lymphocytic leukemia and is also licensed for the management of indolent non-Hodgkin's lymphoma (NHL) in countries such as Switzerland and Canada. Clinical evidence from studies in patients with NHL suggests that fludarabine monotherapy is at least as effective, if not better, than conventional therapies such as cyclophosphamide, vincristine, prednisone (CVP) for the first- and second-line treatment of NHL, achieving objective response rates of 31-84%. The combination of fludarabine with other chemotherapeutic agents such as cyclophosphamide or mitoxantrone also provides the clinician with additional useful treatment options in this setting.

Long-term follow-up of front-line treatment of hairy cell leukemia with 2-chlorodeoxyadenosine.

Background And Objectives: Although remission of hairy cell leukemia (HCL) after treatment with 2-chlorodeoxyadenosine (2-CdA) appears to be long lasting, few reports currently provide results from follow-up exceeding 5 years.

Design And Methods: We reviewed our HCL patients treated with front-line 2-CdA (by 2-hour infusion) either for 5 consecutive days at 0.14 mg/kg/day (daily subset, n=21) or once a week at 0.

The role of anthracyclines in combination chemotherapy for the treatment of follicular lymphoma: retrospective study of the Intergruppo Italiano Linfomi on 761 cases.

In order to elucidate the role of anthracycline based combination chemotherapy regimens for the treatment of follicular lymphoma we conducted a retrospective study on a large series of patients with a histologically confirmed diagnosis of follicular lymphoma. The Italian lymphoma intergroup (ILI) promoted a retrospective study of patients with follicular lymphoma treated in cooperative trials between 1985 and 1996. Six hundred and thirty three cases were treated with an anthracycline-containing regimen and 128 patients were treated without anthracyclines.

Complications of cytotoxic chemotherapy in older patients: focus on myelotoxicity in lymphomas.

The management of the older lymphoma patient with cytotoxic chemotherapy requires knowledge of the pharmacologic effects of age and awareness of the diversity of the older population. The most obvious reason for attenuation of treatment intensity in the elderly is the possibility of a decline in hemopoietic reserve. The research of specific therapeutic protocols is needed to cure the elderly lymphoma patients reducing the risk of important toxic effects.

Extranodal marginal zone B-cell lymphoma of MALT-type of the lung: single-center experience with 12 patients.

The lung is a relatively rare site for mucosa-associated lymphoid tissue (MALT) lymphomas: we report the largest available single-center series of patients with this presentation. From August 1992 to October 2000, 12 patients with untreated primary low-grade MALT lymphoma of the lung were submitted either to chemotherapy alone (n = 8), surgery alone (n = 2) or surgery plus chemotherapy (n = 2). At diagnosis, 6 (50%) were asymptomatic and 6 (50%) had nonspecific pulmonary symptoms.

High-dose therapy with autologous transplantation for Hodgkin's disease: the Bologna experience.

Background And Objectives: In this work we examine the characteristics and outcome of patients with Hodgkin's disease (HD) treated with high-dose therapy (HDT) and autologous transplantation at our Institute between 1982 to 2000.

Design And Methods: A retrospective analysis was performed examining patients' characteristics, prior chemotherapy regimens, pre-transplant disease status, HDT regimen, source of stem cells, time for hematopoietic recovery, complications of transplantation, response rates, overall survival (OS) and relapse-free survival (RFS).

Results: Ninety-seven patients with HD were treated and had estimated 10-year OS and RFS rates of 32% and 60%, respectively.

Early autologous stem-cell transplantation versus conventional chemotherapy as front-line therapy in high-risk, aggressive non-Hodgkin's lymphoma: an Italian multicenter randomized trial.

Purpose: To evaluate the role of early intensification with high-dose therapy (HDT) and autologous stem-cell transplantation (ASCT) as front-line chemotherapy for patients with high-risk, histologically aggressive non-Hodgkin's lymphoma (NHL).

Patients And Methods: We planned a multicenter, randomized trial to compare a conventional chemotherapy regimen of methotrexate with leucovorin rescue, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOP-B; arm A) with an abbreviated regimen of MACOP-B (8 weeks) followed by HDT and ASCT (arm B) for intermediate-high-risk/high-risk patients (according to the age-adjusted International Prognostic Index). From September 1994 to April 1998, 150 patients with aggressive lymphoma were enrolled onto the trial.

Primary bone lymphoma: experience with 52 patients.

Background And Objectives: A retrospective analysis was performed to assess the efficacy of various treatments of non-Hodgkin's primary bone lymphomas (PBL).

Design And Methods: Fifty-two consecutive, previously untreated PBL patients were seen between the years 1982 and 1998. Information was obtained regarding each patient's presentation and clinical course.

Expression of B-lymphocyte-associated transcription factors in human T-cell neoplasms.

In this study we have investigated the expression of three B-cell-associated transcription factors in normal lymphoid tissue and in T-cell neoplasms (three cell lines, and more than 50 biopsy samples). Nuclear OCT-1 immunoreactivity was seen in normal B cells, in many extrafollicular T cells, and in a heterogeneous pattern (ranging in intensity from weak to moderate) in most T-cell neoplasms. OCT-2 immunostaining was primarily restricted in normal lymphoid tissue to B cells, and was absent from most T-cell neoplasms.

Primary mediastinal B-cell lymphoma: high frequency of BCL-6 mutations and consistent expression of the transcription factors OCT-2, BOB.1, and PU.1 in the absence of immunoglobulins.

Although primary mediastinal (thymic) large B-cell lymphoma has been primarily studied, its precise phenotype, molecular characteristics, and histogenesis are still a matter of debate. The International Extranodal Lymphoma Study Group collected 137 such cases for extensive pathological review. Histologically, the lymphomatous growth was predominantly diffuse with fibrosis that induced compartmentalized cell aggregation.

Induction chemotherapy strategies for primary mediastinal large B-cell lymphoma with sclerosis: a retrospective multinational study on 426 previously untreated patients.

Background And Objectives: This multinational retrospective study compares the outcomes of patients with primary mediastinal large B-cell lymphoma (PMLBCL) with sclerosis after first-generation (dose-intensive regimens), third-generation (alternating regimens) and high-dose chemotherapy strategies, frequently with adjuvant radiation therapy.

Design And Methods: Between August 1981 and December 1999, a total of 426 previously untreated patients with confirmed diagnosis were enrolled in 20 institutions to receive combination chemotherapy with either first generation (CHOP or CHOP-like) regimens, third generation (MACOP-B, VACOP-B, ProMACE CytaBOM) regimens or high-dose chemotherapy (HDS/ABMT).

Results: With chemotherapy, complete response (CR) rates were 49% (50/105), 51% (142/277) and 53% (23/44) with first generation, third generation and high-dose chemotherapy strategies, respectively; partial response (PR) rates were 32%, 36% and 35%, respectively.

Non-Hodgkin's lymphoma: the evolving role of purine analogues.

Indolent non-Hodgkin's lymphoma is the commonest form of lymphoma in the USA and Europe, with a long natural history with multiple responses and relapses. Indolent lymphomas include follicular lymphomas (the more frequent subtype), immunocytoma, and small lymphocytic lymphomas according to the Revised European-American Lymphoma classification. The tendency has been to use simple oral medication until patients have more advanced aggressive disease but new agents such as the purine analogues have led to re-evaluation of this approach.

Nongastric marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue.

A retrospective survey of patients with pathologically reviewed extragastric mucosa-associated lymphoma tissue (MALT) lymphomas from 20 institutions was performed. A total of 180 patients with histologically confirmed diagnosis of extragastric MALT lymphomas were studied. Their median age was 59 years (range, 21-92 years).

Ifosfamide, epirubicin and etoposide regimen as salvage and mobilizing therapy for relapsed/refractory lymphoma patients.

Background And Objectives: Therapy for relapsed/refractory lymphomas should be based only on drugs not included in the front-line chemotherapy regimens. We adopted the strategy of using salvage chemotherapy to debulk disease and simultaneously mobilize stem cells, using a regimen based on ifosfamide and etoposide, (drugs not usually used for front-line treatment).

Design And Methods: A three-drug combination of ifosfamide, epirubicin and etoposide (IEV) was used to treat 62 patients with relapsing or refractory aggressive non-Hodgkin's lymphoma (NHL; n=51) or Hodgkin's disease (HD; n=11).

The modified International Prognostic Index can predict the outcome of localized primary intestinal lymphoma of both extranodal marginal zone B-cell and diffuse large B-cell histologies.

We have previously reported on the efficacy of a modified International Prognostic Index (MIPI) in predicting the outcome of patients with primary gastric lymphoma. This prompted the retrospective analysis of a large series of patients with primary intestinal lymphoma (PIL) of both diffuse large B-cell (DLCL) and low-grade (extranodal marginal zone B-cell lymphoma, MZL) histology. Clinical records of 122 patients with localized primary intestinal lymphoma of MZL (n=35) and DLCL (n=87) histology, confirmed by an ad hoc expert panel of pathologists, were reviewed.

T(11;18) is a marker for all stage gastric MALT lymphomas that will not respond to H. pylori eradication.

Background & Aims: Eradication of Helicobacter pylori leads to cure of gastric mucosa-associated lymphoid tissue (MALT) lymphoma in 75% of localized cases. However, prolonged follow-up is necessary to determine whether a lymphoma responds to therapy. In a small series of cases, we showed that t(11;18)(q21;q21)-positive MALT lymphomas failed to respond to H.
