The International Prognostic Index determines the outcome of patients with nodal mature T-cell lymphomas.

The World Health Organization (WHO) lymphoma classification recognises anaplastic large cell lymphoma (ALCL), angioimmunoblastic lymphoma (AIL) and peripheral T-cell lymphoma, unspecified (PTCU) as nodal mature T-cell lymphomas. Little is known about long-term outcome and prognostic factors of these diseases. A retrospective analysis on 125 patients with ALCL, AIL or PTCU was performed to evaluate outcome parameters, taking into account histological subtype and the International Prognostic Index (IPI).

Lenograstim after autologous peripheral blood progenitor cell transplantation: results of a double-blind, randomized trial.

A phase III, randomized, double-blind, placebo-controlled, multi-center trial was conducted in order to compare the incidence of microbiologically defined infections occurring after high-dose chemotherapy (HDT) and ASCT in 98 patients given lenograstim (Granocyte) and 94 patients given placebo after transplantation. Hematopoietic recovery, the use of i.v.

Conservative management of gastric lymphoma: the treatment option of choice.

The study was initiated to assess the safety and effectiveness of primary chemotherapy (CHT) followed by radiotherapy (RT) compared to surgery prior to CHT and/or RT in the management of localized gastric lymphoma. Ninety-two patients treated between 1985 and 2000 were included in a retrospective analysis. Sixty patients received primary CHT followed by extended field or involved field RT.

Genomic profiling of peripheral T-cell lymphoma, unspecified, and anaplastic large T-cell lymphoma delineates novel recurrent chromosomal alterations.

To characterize genetic alterations in peripheral T-cell lymphoma, not otherwise specified (PTCL NOS), and anaplastic large T-cell lymphoma (ALCL), 42 PTCL NOS and 37 ALCL [17 anaplastic large cell kinase (ALK)-negative ALCL, 9 ALK-positive ALCL, 11 cutaneous ALCL] were analyzed by comparative genomic hybridization. Among 36 de novo PTCL NOS, recurrent chromosomal losses were found on chromosomes 13q (minimally overlapping region 13q21, 36% of cases), 6q and 9p (6q21 and 9p21-pter, in 31% of cases each), 10q and 12q (10q23-24 and 12q21-q22, in 28% of cases each), and 5q (5q21, 25% of cases). Recurrent gains were found on chromosome 7q22-qter (31% of cases).

Immunophenotyping is an independent factor for risk stratification in AML.

Background: Chromosomal abnormalities are one of the most important prognostic factors in acute myeloid leukemia (AML). However, only a limited number of patients have such informative chromosomal abnormalities. The prognostic value of immunophenotyping in this disease is still unclear.

Treatment results of aggressive B non-Hodgkin's lymphoma in advanced age considering comorbidity.

The aim of this retrospective single institution study was to investigate the long-term outcome of sequential chemotherapy (CHT) and radiotherapy (RT) in patients >/= 70 years old, considering the International Prognostic Index (IPI) for high-grade non-Hodgkin's lymphoma (NHL) and comorbidity. The study involved 106 patients aged 70 years and above, treated between 1986 and 1998, for diffuse large B-cell NHL (DLBCL); 57% had localized disease (stage I or II) and 43% had advanced disease (stage III or IV). All patients received four to six cycles of CHOP (cyclophosphamide, hydroxy-daunorubicin, oncovin, prednisone) CHT at 14-21 d intervals, followed in 69 cases by extended-field or involved-field RT.

The impact of autologous stem cell transplantation on the prognosis of mantle cell lymphoma: a joint analysis of two prospective studies with 46 patients.

Introduction: The purpose of this analysis was to investigate if early sequential high-dose therapy with autologous stem cell transplantation (ASCT) can improve the poor prognosis of patients with disseminated mantle cell lymphoma (MCL).

Patients And Methods: A joint analysis of two parallel single center studies was performed. Both were characterized by a sequential high-dose therapy consisting of an intensive chemotherapy ('HAM' or 'Dexa-BEAM') for mobilization of peripheral blood stem cells and induction of minimal disease followed by a total body irradiation-containing myeloablative regimen and ASCT.

Autologous stem cell transplantation for follicular lymphoma: no benefit for early transplant?

Autologous stem cell transplantation (SCT) is widely used as salvage treatment for patients with relapsed follicular lymphoma (FL). Although SCT can induce prolonged remissions, it does not appear to be curative in the vast majority of patients. The purpose of this study was to investigate if incorporation of SCT into first-line therapy can improve its efficacy.

Dose-dependent effect of etoposide in combination with busulfan plus cyclophosphamide as conditioning for stem cell transplantation in patients with acute myeloid leukemia.

To evaluate the efficacy and toxicity of two different etoposide (VP-16) dosages (30 or 45 mg/kg) in combination with busulfan/cyclophosphamide as conditioning therapy followed by stem cell transplantation in acute myeloid leukemia (AML), 90 patients with AML received either 30 mg/kg (n = 60) or 45 mg/kg (n = 30) etoposide in combination with busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg). The stem cell source was allogeneic related bone marrow (BM) (n = 53), allogeneic unrelated BM (n = 5), allogeneic unrelated peripheral blood (PBSC) (n = 2), syngeneic BM (n = 2), autologous BM purged (n = 9) or unpurged (n = 9), autologous PBSC (n = 10). Fifty-six patients (62%) were in first CR, 26 (29%) were > first CR, and eight (9%) were transplanted in relapse.

Clinicopathogenetic significance of chromosomal abnormalities in patients with blastic peripheral B-cell lymphoma. Kiel-Wien-Lymphoma Study Group.

So far, reproducible histomorphologic and immunological criteria to distinguish clinicopathologic subtypes of blastic peripheral B-cell non-Hodgkin's lymphoma (BBCL), especially centroblastic (cb) and immunoblastic (ib) lymphomas, for daily diagnostic use are still lacking. Therefore, we correlated the cytogenetic findings in 126 patients with BBCL with histopathologic diagnoses. Subclassification of cb and ib lymphomas relied on the criteria defined in the updated Kiel classification; these subtypes are also listed in the Revised European-American Lymphoma (REAL) classification and in a preliminary report on the newly established World Health Organization classification, to investigate their clinical significance.

Myeloablative radiochemotherapy followed by reinfusion of purged autologous stem cells for Waldenström's macroglobulinaemia.

Waldenström's macroglobulinaemia (WM) is an incurable lymphoproliferative disorder. The purpose of this study was to investigate the role of autologous peripheral blood stem cell transplantation (ASCT) for the treatment of WM. Seven patients (untreated or after first-line therapy) with symptomatic WM underwent two or three cycles of Dexa-BEAM chemotherapy + G-CSF with stem cell harvesting and proceeded to total body irradiation and high-dose cyclophosphamide followed by reinfusion of ex-vivo B-cell-depleted stem cells.

Early stem cell transplantation for chronic lymphocytic leukaemia: a chance for cure?

B-cell chronic lymphocytic leukaemia (CLL) cannot be cured by conventional therapy. To improve the prognosis of patients with CLL, we have designed a sequential treatment strategy that comprises intensive chemotherapy for mobilization of peripheral blood progenitor cells (PBPCs) and induction of minimal disease, followed by high-dose radiochemotherapy with stem cell reinfusion and post-transplant molecular monitoring by polymerase chain reaction (PCR) amplification of the complementary determining region III (CDRIII) gene. In a prospective study, we have evaluated this protocol in 18 patients with CLL, also including early stages of the disease.

[Long term results of treatment of highly-malignant non-Hodgkin lymphoma in the elderly (70 years and older)].

Objective: To assess retrospectively the results of long-term combined chemotherapy and radiotherapy of patients 70 years of older, taking into account the international non-Hodgkin lymphoma (NHL) prognostic index of Shipp as well as the dose-intensity.

Patients And Methods: Of 303 patients treated for aggressive NHL 100 were aged 70 years or more (median age 76 years). Localized stages I or II were present in 56, advanced stages III or IV in 44, and 38 had extranodal tumours.

Sequential high-dose therapy and autologous stem cell transplantation for treatment of mantle cell lymphoma.

Background: Mantle cell lymphoma (MC) is not curable with conventional chemotherapy. To improve the prognosis of patients with this disease, we prospectively studied an intensive sequential therapy consisting of the Dexa-BEAM regimen (dexamethasone, BCNU, etoposide, ara-C, melphalan) followed by myeloablative therapy with autologous stem cell reinfusion.

Patients And Methods: Nine consecutive patients with stage III/IV MC were included.

Significance of cytogenetic findings for the clinical outcome in patients with T-cell lymphoma of angioimmunoblastic lymphadenopathy type.

Purpose: The aim of this study was to evaluate the significance of cytogenetic findings for the clinical outcome of patients with Angioimmunoblastic Lymphadenopathy (AILD)-Type T-cell lymphoma.

Materials And Methods: In a retrospective analysis, the cytogenetic findings of 50 patients with AILD-type T-cell lymphoma were correlated with the frequency of spontaneous and therapy-induced remissions and with survival using the statistical methods of Kaplan and Meier and the model of Cox for multivariate analysis. Treatment was not uniform because the patients were treated in different hospitals during a period of 8 years and because a standard therapy has not yet been established.

Combined immunophenotyping and karyotyping in peripheral T cell lymphomas demonstrating different clonal and nonclonal chromosome aberrations in T helper cells.

Combined immunophenotyping and karyotyping was performed in seven cases of peripheral T cell lymphoma with complex aberrant clones. Various lymphocytic cell populations entered mitosis, whereas all aberrant cells belonged to the T helper/inducer cell population. Lymphomas with the same recurrent chromosome aberrations, i.

[Combined conservative treatment of localized stomach lymphoma].

In a twelve-year period (1980-1992) 23 patients (9 men, 14 women; mean age 65 [25-82] years) with malignant non-Hodgkin lymphoma of the stomach, in localized stage I or II (Ann Arbor classification), were given chemo- and radiotherapy without preceding operation. The results were compared with those of a group of 34 patients (19 men, 15 women; mean age 55 [17-77] years) who had been admitted during the same period, having first been treated by surgical resection and most of them additionally by chemo- and/or radiotherapy. Three not previously operated patients with inadequate response to chemotherapy subsequently underwent laparotomy and remained in remission after further treatment.

Cytogenetic findings and results of combined immunophenotyping and karyotyping in Hodgkin's disease.

Cytogenetic studies were performed in 21 cases of Hodgkin's disease. Fourteen cases revealed chromosomally aberrant clones which could be fully described in 12 cases. Two cases showed different unrelated clones and five cases only single cell aberrations.

Clonal t(8;14)(p11;q31) in a case of reactive lymphoproliferation.

A clone with an unbalanced translocation t(8;14)(p11;q31), resulting in deletion of the distal part of the long arm of chromosome 14, 14q31 --> 14qter, was detected in a case of Piringer's lymphadenitis. Histopathologically no atypical cells or other signs of malignant lymphoma were found. Southern blot analyses showed no rearrangement of the immunoglobulin heavy chain gene (IGH) or the T-cell receptor gamma chain (TCRG) gene.

High-dose chemotherapy and autologous bone marrow transplantation in relapsing angioimmunoblastic lymphadenopathy with dysproteinemia (AILD).

Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) or lymphogranulomatosis X is a lymphoproliferative disorder with a histological picture resembling that of reactive lesions but with frequent cytogenetic and molecular abnormalities characteristic of malignant T cell lymphoma. Clinically, the disease runs a fatal course in the majority of patients although occasional spontaneous remissions have been observed. Median survival approaches only 1 year even with the most effective treatment protocols implemented so far.

Plasma levels of soluble CD8 antigen and interleukin-2 receptor antigen in patients with hairy cell leukemia, relationship with splenectomy and with clinical response to therapy.

A soluble form of CD8 antigen (sCD8) has been shown to be released by activated CD8 + lymphocytes. Measurements of sCD8 may serve as an index of suppressor/cytotoxic cell activity. To assess the clinical significance of this observation in response to malignancy, we have investigated the sCD8 concentrations in 38 patients with hairy cell leukemia (HCL) not yet treated with any systemic therapy.
