Diffuse large B-cell lymphoma in the elderly: impact of prognosis, comorbidities, geriatric assessment, and supportive care on clinical practice. An International Society of Geriatric Oncology (SIOG) expert position paper.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma in the elderly, and is increasing in incidence. Although significant therapeutic advances have recently been made in the care of older patients with DLBCL, based upon results of randomized clinical trials, many older patients are not eligible for such trials due to comorbidities and functional decline. Pre-treatment evaluation of older patients to ascertain potential tolerance to therapy is especially important in therapeutic decisions for this population.

Prognostication of diffuse large B-cell lymphoma in the rituximab era.

Predicting the prognosis of patients diagnosed with diffuse large B-cell lymphoma (DLBCL) has been a moving target over the last several years. While earlier prognostic models relied mainly on such clinical variables as age, stage of disease, and performance status, it has become evident from gene-expression microarray studies that DLBCL is a heterogeneous disease in terms of molecular pathogenesis and cell of origin. Despite providing considerable insight into disease biology, these techniques are not widely available and are, at least at present, not applicable to routine clinical practice.

Infectious complications of chronic lymphocytic leukemia.

Infectious complications continue to be one of the major causes of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL). The pathogenesis of infections in these patients is multifactorial. Hypogammaglobulinemia is an important predisposing factor for infection in patients with early-stage disease and for those treated with conventional alkylating agents.

High-dose carmustine, etoposide, and cisplatin for autologous stem cell transplantation with or without involved-field radiation for relapsed/refractory lymphoma: an effective regimen with low morbidity and mortality.

Over a 10-year period (January 1993 to October 2002), 101 relapsed or refractory non-Hodgkin lymphoma patients were treated at our center with high-dose chemotherapy and autologous transplantation. The median patient age was 54 years (range, 25-70 years). Thirty-two patients had indolent (low-grade), 42 had aggressive (intermediate-grade), and 27 had very aggressive (high-grade) non-Hodgkin lymphoma.

Hematopoietic recovery after unrelated umbilical cord-blood allogeneic transplantation in adults treated with in vivo stem cell factor (R-MetHuSCF) and filgrastim administration.

Transplantation with unrelated umbilical cord blood (UCB) is marked by delayed hematologic recovery. This report summarizes two adults with chronic myelogenous leukemia (CML), who received myeloablative conditioning followed by infusion of a non-expanded single UCB graft. These CML patients were enrolled in a clinical trial incorporating concomitant in vivo administration of stem cell factor (R-MetHuSCF) and filgrastim from day of UCB infusion until attained hematopoietic recovery.

Cancer gene therapy: scientific basis.

Gene therapy of cancer has been one of the most exciting and elusive areas of therapeutic research in the past decade. Critical developments have occurred in gene therapy targeting cancer cells, cancer vasculature, the immune system, and the bone marrow, itself often the target for severe toxicity from therapeutic agents. We review some recent developments in the field.
