Despite multiple disparate prognostic risk analysis systems for evaluating clinical outcome for patients with myelodysplastic syndrome (MDS), imprecision persists with such analyses. To attempt to improve on these systems, an International MDS Risk Analysis Workshop combined cytogenetic, morphological, and clinical data from seven large previously reported(More)
Despite having several characteristics of naïve B cells, chronic lymphocytic leukemia (CLL) cells have been shown in some cases to have somatically mutated Ig variable region genes, indicating that the cell of origin has passed through the germinal center. A previous study of patients with CLL found an association between lack of somatic mutation and(More)
Autoimmune complications are common in chronic lymphocytic leukemia (CLL), occurring in up to a quarter of all patients during the course of the illness. By far the most common manifestation is autoimmune hemolytic anemia (AIHA), followed by immune thrombocytopenia (ITP). It is not true to say that autoimmunity is confined to the formed elements of the(More)
We studied the incidence of myelodysplastic syndrome (MDS) in a population served by one district general hospital over a 10-year period (1981-90). Cases were sought through investigation of individuals presenting with suggestive peripheral blood findings. 279 new cases were diagnosed in a population rising from 203,000 to 226,000 over the study period. The(More)
BACKGROUND Previous studies of patients with chronic lymphocytic leukaemia reported high response rates to fludarabine combined with cyclophosphamide. We aimed to establish whether this treatment combination provided greater survival benefit than did chlorambucil or fludarabine. METHODS 777 patients with chronic lymphocytic leukaemia requiring treatment(More)
Although the presence or absence of somatic mutations in the immunoglobulin variable region (IgV(H)) genes in chronic lymphocytic leukemia (B-CLL) identifies subtypes with very different prognoses, the assay is technically complex and unavailable to most laboratories. CD38 expression has been suggested as a surrogate marker for the 2 subtypes. IgV(H)(More)
Chronic lymphocytic leukaemia is the commonest of the leukaemias and occurs most often in the elderly. The identification of presenting features that correlate adversely or favourably with survival has allowed the rational development of new treatment strategies.
INTRODUCTION Patients with chronic lymphocytic leukaemia (CLL) have progressive immunodeficiency and infection is the commonest cause of death. This review seeks to identify the extent of the abnormality, its cause, clinical significance and any possible remedy. SOURCES OF DATA TJH has studied CLL for the past 40 years and has scanned or read every paper(More)
Chronic lymphocytic leukemia (CLL) is a lymphoproliferative disease with a highly variable outcome. The prognosis of patients with CLL may be predicted using a number of biomarkers, including the level of CD38 expression at the leukemic cell surface. This study investigates the hypothesis that CD38 expression by CLL cells reflects interactions with(More)
We studied 270 patients with Binet stage A chronic lymphocytic leukaemia looking for adverse prognostic factors. In a multivariate analysis the following features were found to be risk factors for disease progression: atypical lymphocyte morphology (defined as either > 10% prolymphocytes or > 15% lymphocytes with cleaved nuclei or lymphoplasmacytoid cells);(More)
