BACKGROUND The effect of interferon-alpha 2b (IFN-alpha-2b) on progression-free and overall survival as well as quality of life (QoL) was studied in mainly elderly patients with multiple myeloma (MM), who reached a plateau phase after melphalan/prednisone induction. PATIENTS AND METHODS In an open phase III trial, 262 patients, median age 69 years (range(More)
UNLABELLED This study assesses whether new treatment strategies developed in clinical trials translate into improved survival for multiple myeloma (MM) patients in the Netherlands. All patients diagnosed with MM in the Northern part of the Netherlands between 1989 and 2005 were retrieved from two regional population-based cancer registries. Information on(More)
Long-term complete remission in IgD multiple myeloma (MM) is rare. This case report describes a patient with a stage IIIB IgD-MM, who was treated with conventional melphalan and prednisone chemotherapy. The monoclonal protein disappeared after four cycles and therapy was discontinued after 14 cycles. Re-evaluation after a follow up of more than 8 years(More)
The in vitro proliferative response against a recombinant 65 kD Mycobacterium bovis protein that has 100% homology with the 65 kD protein of M tuberculosis was tested in synovial fluid and peripheral blood mononuclear cells from patients with rheumatoid arthritis (RA) and other types of chronic arthritis. An acetone precipitate (AP) of M tuberculosis, and a(More)
Serum syndecan-1 was investigated in 189 patients with newly diagnosed monoclonal proteinemia [the diagnoses were multiple myeloma (66), monoclonal gammopathies of undetermined significance (MGUS; n=54), provisional MGUS (no bone marrow examination performed; n=69)] and 36 controls. Syndecan-1 levels ranged widely between all diagnostic categories and were(More)
Prospective studies on the risk of malignant transformation in patients with monoclonal gammopathy of undetermined significance (MGUS) and factors predictive of survival are lacking. The Dutch Comprehensive Cancer Centre West, comprising 1.6 million inhabitants, initiated a prospective hospital-based cohort study on 1464 patients with newly diagnosed(More)
BACKGROUND The treatment of posttransplant lymphoproliferative disorder (PTLD) remains empirical. We review our treatment of seven cases of PTLD consisting of five interventions: 1) reduction of immunosuppression; 2) antiviral drugs; 3) interferon-alpha; 4) gamma-globulins; and 5) anti-CD19 monoclonal antibodies. METHODS AND RESULTS; Seven consecutive(More)
We determined interleukin-6 (IL-6) levels in the serum of 212 well-defined patients with newly diagnosed paraproteinaemia and evaluated its discriminatory value and prognostic role in multiple myeloma (MM). Results were compared with serum neural cell adhesion molecule and beta-2-microglobulin, both established prognostic MM markers.(More)
AIM The aim of this systematic review is to summarise all available data on the effect of a geriatric evaluation on the multidisciplinary treatment of older cancer patients, focussing on oncologic treatment decisions and the implementation of non-oncologic interventions. METHODS A systematic search in MEDLINE and EMBASE for studies on the effect of a(More)
