High-dose alkylating chemotherapy in BRCA-altered triple-negative breast cancer: the randomized phase III NeoTN trial.

Exploratory analyses of high-dose alkylating chemotherapy trials have suggested that BRCA1 or BRCA2-pathway altered (BRCA-altered) breast cancer might be particularly sensitive to this type of treatment. In this study, patients with BRCA-altered tumors who had received three initial courses of dose-dense doxorubicin and cyclophosphamide (ddAC), were randomized between a fourth ddAC course followed by high-dose carboplatin-thiotepa-cyclophosphamide or conventional chemotherapy (initially ddAC only or ddAC-capecitabine/decetaxel [CD] depending on MRI response, after amendment ddAC-carboplatin/paclitaxel [CP] for everyone). The primary endpoint was the neoadjuvant response index (NRI).

Rituximab in patients with primary CNS lymphoma (HOVON 105/ALLG NHL 24): a randomised, open-label, phase 3 intergroup study.

Background: The prognosis for primary CNS lymphoma has improved with the use of high-dose methotrexate-based chemotherapy, but patient outcomes remain poor. Rituximab, a chimeric monoclonal antibody that targets the CD20 cell surface protein, has substantial activity in systemic CD20-positive diffuse large B-cell lymphoma, but its efficacy in primary CNS lymphoma is unknown and low penetration of the large rituximab molecule through the blood-brain barrier could limit its effect. We aimed to investigate the addition of rituximab to a high-dose methotrexate-based chemotherapy regimen in patients with newly diagnosed primary CNS lymphoma.

Impact of hyperglycemia on the efficacy of chemotherapy-A systematic review of preclinical studies.

Background: Antineoplastic agents can provoke hyperglycemia in cancer patients with and without diabetes mellitus. We systematically reviewed the impact of hyperglycemia on the efficacy of chemotherapy.

Methods: MEDLINE was searched for preclinical intervention studies which compared chemotherapy response in hyperglycemic and euglycemic conditions.

Treatment of secondary central nervous system lymphoma with intrathecal rituximab, high-dose methotrexate, and R-DHAP followed by autologous stem cell transplantation: results of the HOVON 80 phase 2 study.

The prognosis of central nervous system (CNS) relapse of systemic non-Hodgkin lymphoma is poor with 1-year survival historically at 0% to 20%. Aiming to improve these results, we performed a multicenter phase 2 study in patients with a CNS relapse, with or without concurrent systemic relapse. Treatment consisted of 2 cycles of R-DHAP alternating with high-dose methotrexate (MTX) and was combined with intrathecal rituximab.

Neurocognitive function of lymphoma patients after treatment with chemotherapy.

Background: Chemotherapy has been shown to cause brain changes and to compromise cognitive function in cancer survivors. Knowledge about this matter is of vital importance for good clinical practice and insights into neurological aging. However, most studies have been conducted among breast cancer patients.

Health-related physical fitness in patients with multiple myeloma or lymphoma recently treated with autologous stem cell transplantation.

Objectives: We aimed to examine health-related physical fitness and its demographic and clinical correlates in patients recently treated with autologous stem cell transplantation.

Design: Cross-sectional study.

Methods: In 109 patients (multiple myeloma: n=58, lymphoma: n=51, median age: 55, range: 19-67 years) maximal exercise testing was conducted to assess cardiorespiratory fitness (VO).

[Recurrent upper respiratory tract infections during and after rituximab therapy].

Rituximab maintenance therapy is indicated for the treatment of patients with non-Hodgkin's lymphoma (NHL) who responded to induction therapy. More than 10% of patients will develop rituximab-induced upper respiratory tract infections (URTIs). These infections are usually mild in patients receiving first-line or second-line treatment.

Chemotherapy as primary treatment for brain metastases from breast cancer: analysis of 115 one-year survivors.

Purpose: Given the potential toxicity of whole brain radiotherapy, we introduced systemic therapy as possible primary treatment for brain metastases (BM) from breast cancer. This study aims to evaluate the feasibility of this therapeutic approach.

Methods: Review of 115 breast cancer patients treated for BM with at least 1 year of follow-up.

Dose intensity of chemotherapy in patients with relapsed Hodgkin's lymphoma.

Purpose: High-dose chemotherapy (HDCT) followed by autologous stem-cell transplantation (PBSCT) has become the standard treatment for patients with relapsed Hodgkin's lymphoma (HL). The intensity of treatment needed is unclear. This European intergroup study evaluated the impact of sequential high-dose chemotherapy (SHDCT) before myeloablative therapy.

A simple and safe method for 131I radiolabeling of rituximab for myeloablative high-dose radioimmunotherapy.

The aim of this study was to develop a safe and simple radiolabeling and purification procedure for high-dose (131)I-rituximab for treatment of patients with non-Hodgkin's lymphoma. As the starting point, the conventional Iodogen-coated vial method was applied. After the iodogen-coated monoclonal antibody (mAb) method, a labeling method involving much lower amounts of iodogen was assessed.

Myeloablative allogeneic versus autologous stem cell transplantation in adult patients with acute lymphoblastic leukemia in first remission: a prospective sibling donor versus no-donor comparison.

While commonly accepted in poor-risk acute lymphoblastic leukemia (ALL), the role of allogeneic hematopoietic stem cell transplantation (allo-SCT) is still disputed in adult patients with standard-risk ALL. We evaluated outcome of patients with ALL in first complete remission (CR1), according to a sibling donor versus no-donor comparison. Eligible patients (433) were entered in 2 consecutive, prospective studies, of whom 288 (67%) were younger than 55 years, in CR1, and eligible to receive consolidation by either an autologous SCT or an allo-SCT.

Poor outcomes of chronic active Epstein-Barr virus infection and hemophagocytic lymphohistiocytosis in non-Japanese adult patients.

Chronic active Epstein-Barr virus infection manifests as a combination of persistent infectious mononucleosis-like symptoms and high viral load in apparently immunocompetent patients. It is closely related to Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis. These 2 abnormal Epstein-Barr virus-associated diseases are seldom reported in individuals other than Japanese children and adolescents.

Chemotherapy plus involved-field radiation in early-stage Hodgkin's disease.

Background: Treatment of early-stage Hodgkin's disease is usually tailored in line with prognostic factors that allow for reductions in the amount of chemotherapy and extent of radiotherapy required for a possible cure.

Methods: From 1993 to 1999, we identified 1538 patients (age, 15 to 70 years) who had untreated stage I or II supradiaphragmatic Hodgkin's disease with favorable prognostic features (the H8-F trial) or unfavorable features (the H8-U trial). In the H8-F trial, we compared three cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) combined with doxorubicin, bleomycin, and vinblastine (ABV) plus involved-field radiotherapy with subtotal nodal radiotherapy alone (reference group).

Gene-expression and immunohistochemical study of specific T-cell subsets and accessory cell types in the transformation and prognosis of follicular lymphoma.

Purpose: Despite the generally favorable clinical course in follicular lymphoma (FL), a minority of patients have a poor prognosis-with death within 3 years of diagnosis-most often due to transformation to aggressive disease.

Patients And Methods: In this study, we analyzed the potential of predicting early transformation on the basis of gene expression and immunologic parameters in FL biopsy samples taken at diagnosis.

Results: At the gene-expression level, FL is a highly uniform disease at the time of diagnosis, precluding the detection of sufficiently validated prognostic gene-expression profiles suitable for a clinical setting.

Risk of second cancer after treatment of aggressive non-Hodgkin's lymphoma; an EORTC cohort study.

Background And Objectives: Second cancer has been associated with non-Hodgkin's Lymphoma (NHL) treatment, but few studies have addressed this issue considering specific treatments.

Design And Methods: We estimated risk by standardized incidence ratios (SIR) and absolute excess risk (AER) based on general population rates (European Network of Cancer Registries) in 748 patients (aged 15-82 years) treated for aggressive NHL in four successive EORTC (European Organization for Research on Treatment of Cancer) trials.

Results: All patients received fully-dosed CHOP-like chemotherapy, 65% received involved-field radiotherapy and 14% high-dose treatment.

Long-term risk of cardiovascular disease after treatment for aggressive non-Hodgkin lymphoma.

Cardiovascular disease frequently occurs after lymphoma therapy, but it is common in the general population too. Therefore, risk estimation requires comparison to population-based rates. We calculated risk by standardized incidence ratios (SIRs) and absolute excess risks (AERs) per 10,000 person-years based on general population rates (Continuous Morbidity Registry Nijmegen) in 476 (Dutch and Belgian) patients with aggressive non-Hodgkin lymphoma (NHL) treated with at least 6 cycles of doxorubicin-based chemotherapy in 4 European Organization for Research on Treatment of Cancer (EORTC) trials (1980-1999).

Late non-neoplastic events in patients with aggressive non-Hodgkin's lymphoma in four randomized European Organisation for Research and Treatment of Cancer trials.

Background: A significant proportion of patients with aggressive non-Hodgkin's lymphoma (NHL) become long-term survivors. A European Organisation for Research and Treatment of Cancer database of patients with aggressive NHL, consistently treated with doxorubicin-based chemotherapy since 1980, afforded the possibility to explore late complications in this patient group.

Patients And Methods: Of 951 randomized patients, complete data on late complications could be collected in 757 patients who were alive > or = 2 years after the start of therapy and were seen at yearly follow-ups (median follow-up, 9.

Overall and event-free survival are not improved by the use of myeloablative therapy following intensified chemotherapy in previously untreated patients with multiple myeloma: a prospective randomized phase 3 study.

We compared the efficacy of intensified chemotherapy followed by myeloablative therapy and autologous stem cell rescue with intensified chemotherapy alone in patients newly diagnosed with multiple myeloma. There were 261 eligible patients younger than 66 years with stage II/III multiple myeloma who were randomized after remission induction therapy with vincristine, adriamycin, dexamethasone (VAD) to receive intensified chemotherapy, that is, melphalan 140 mg/m(2) administered intravenously in 2 doses of 70 mg/m(2) (intermediate-dose melphalan [IDM]) without stem cell rescue (n = 129) or the same regimen followed by myeloablative therapy consisting of cyclophosphamide, total body irradiation, and autologous stem cell reinfusion (n = 132). Interferon-alpha-2a was given as maintenance.

Rituximab treatment results in impaired secondary humoral immune responsiveness.

In lymphoma patients, treatment with chimeric CD20 monoclonal antibodies (rituximab) results in a depletion of normal and malignant B cells, persisting for 6 to 9 months. This B-cell depletion leads neither to a decrease in immunoglobulin levels nor an increase in the number of infectious complications. However, the effect of rituximab treatment on the immune responsiveness is unknown.
