Prior genome-wide association (GWA) studies have identified 10 susceptibility loci for risk of chronic lymphocytic leukemia (CLL). To identify additional loci, we performed a GWA study in 407 CLL cases (of which 102 had a family history of CLL) and 296 controls. Moreover, given the strong familial risk of CLL, we further subset our GWA analysis to the CLL(More)
Non-Hodgkin's lymphoma (NHL) is a cancer closely associated with immune function, and the tumor necrosis factor (TNF) G-308A promoter polymorphism, which influences immune function and regulation, was recently reported by the InterLymph Consortium to be associated with NHL risk. TNF signaling activates the nuclear factor-kappaB (NF-kappaB) canonical(More)
To identify susceptibility loci for non-Hodgkin lymphoma subtypes, we conducted a three-stage genome-wide association study. We identified two variants associated with follicular lymphoma at 6p21.32 (rs10484561, combined P = 1.12 x 10(-29) and rs7755224, combined P = 2.00 x 10(-19); r(2) = 1.0), supporting the idea that major histocompatibility complex(More)
Improved medical care could have altered the clinical presentation and survival of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) complicated by autoimmune disease cytopenia (AID cytopenia). We reviewed the clinical characteristics, treatment, and outcome of AID cytopenia that was diagnosed in 75 (4.3%) of 1750 patients with(More)
Building on the prior work of use of pentostatin in chronic lymphocytic leukemia (CLL), we initiated a trial of combined pentostatin (2 mg/m2), cyclophosphamide (600 mg/m2), and rituximab (375 mg/m2) for 65 symptomatic, previously untreated patients. Of 64 evaluable patients, 34 (53%) were high Rai risk, 71% were nonmutated for the immunoglobulin(More)
Genome-wide association studies (GWAS) have previously identified 13 loci associated with risk of chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL). To identify additional CLL susceptibility loci, we conducted the largest meta-analysis for CLL thus far, including four GWAS with a total of 3,100 individuals with CLL (cases) and 7,667 controls.(More)
Although a diagnosis of chronic lymphocytic leukemia (CLL) can have a profound effect on the quality of life (QOL), few studies have objectively measured the QOL of CLL patients or compared it to the general population. We conducted an international, web-based survey of patients with CLL using standardized instruments with published population norms to(More)
BACKGROUND A study was undertaken to analyze the survival of chronic lymphocytic leukemia (CLL) patients relative to age-matched individuals in the general population and determine the age-stratified utility of prognostic testing. METHODS All 2487 patients diagnosed with CLL between January 1995 and June 2008 and cared for in the Mayo Clinic Division of(More)
The peripheral blood absolute lymphocyte count (ALC) recovery after autologous stem cell transplantation has been shown to be an independent prognostic factor for survival for different haematologic malignancies. The role of ALC at diagnosis for follicular (grades 1 and 2) lymphomas (FL) on survival is not well described. The primary objective of this study(More)
Free light chains (FLCs) are the most commonly detected paraproteins in chronic lymphocytic leukemia (CLL). We examined the types of FLC abnormalities and prognostic utility of the FLC assay compared with standard prognostic biomarkers in a prospective cohort of 339 patients with newly diagnosed CLL. Three types of FLC abnormalities were identified:(More)
