The common sequence variants that have recently been associated with cancer risk are particular to a single cancer type or at most two. Following up on our genome-wide scan of basal cell carcinoma, we found that rs401681[C] on chromosome 5p15.33 satisfied our threshold for genome-wide significance (OR = 1.25, P = 3.7 x 10(-12)). We tested rs401681 for(More)
Survivin is a member of the inhibitor of apoptosis protein family that is expressed in G2/M phase. Survivin is overexpressed and associated with parameters of poor prognosis in different human tumors. The role of survivin in the pathogenesis of mantle cell lymphoma (MCL) was examined in a series of typical and blastoid tumors. Survivin was detected as a(More)
JC virus (JCV) acts as an opportunistic virus in immunocompromised human immunodeficiency virus type 1 (HIV-1)-infected patients. The role of peripheral blood cells in central nervous system invasion, before the onset of progressive multifocal leukoencephalopathy (PML), remains controversial. In order to clarify JCV latency or reactivation status in(More)
We conducted a retrospective collaborative study to cytogenetically characterize splenic marginal zone lymphoma (SMZL) and ascertain the prognostic value of chromosomal aberrations. Of 330 cases, 72% displayed an aberrant karyotype, 53% were complex, and 29% had a single aberration. The predominant aberrations were gains of 3/3q and 12q, deletions of 7q and(More)
PURPOSE Fludarabine, cyclophosphamide, and mitoxantrone (FCM) results in a high response rate in previously treated patients with chronic lymphocytic leukemia (CLL). The aim of this study was to investigate FCM as frontline therapy in CLL. EXPERIMENTAL DESIGN Sixty-nine patients under the age of 65 years with active CLL were treated. Patients received six(More)
Mantle cell lymphoma (MCL) is a mature B-cell neoplasm with an aggressive behavior, characterized by the t(11;14)(q13;q32). Several secondary genetic abnormalities with a potential role in the oncogenic process have been described. Studies of large MCL series using conventional cytogenetics, and correlating with proliferation and survival, are scarce. We(More)
PURPOSE WHO classification of myeloid malignancies is based mainly on the percentage of bone marrow (BM) blasts. This is considered from total nucleated cells (TNCs), unless there is erythroid-hyperplasia (erythroblasts ≥ 50%), calculated from nonerythroid cells (NECs). In these instances, when BM blasts are ≥ 20%, the disorder is classified as(More)
BACKGROUND AND OBJECTIVES Patients with follicular lymphoma (FL) in advanced stages are currently deemed incurable with standard treatments. However, FL is considered to be eradicable in the small group of patients presenting with localized disease. The objective of this study was to analyze the clinical features and the outcome of a series of patients with(More)
OBJECTIVES To evaluate the prevalence of falls and their circumstances in non-institutionalized people older than 89 years and living in an urban community. DESIGN Cross-sectional cohort study. SETTING Community-based study. PARTICIPANTS 137 nonagenarians living at home. MEASUREMENTS We evaluated sociodemographic data, capacity to perform basic(More)
Chronic lymphocytic leukemia (CLL) is characterized by a highly variable clinical course. Del(11q) and del(17p), routinely studied by conventional G-banding cytogenetics (CGC) and fluorescence in situ hybridization (FISH), have been related to progression and shorter overall survival. Recently, array-based karyotyping has gained acceptance as a(More)
