PURPOSE Epstein-Barr virus-positive (EBV(+)) diffuse large B-cell lymphoma (DLBCL) of the elderly is a variant of DLBCL with worse outcome that occurs most often in East-Asian countries and is uncommon in the Western hemisphere. We studied the largest cohort of EBV(+) DLBCL, independent of age, treated with rituximab combined with CHOP (R-CHOP) in developed(More)
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) can lead to iron malabsorption through exclusion of the duodenum and proximal jejunum, decreased gastric acidity, and modified diet. Intravenous (IV) iron is a treatment for severe iron deficiency, but the incidence of iron deficiency and the frequency of treatment with IV iron after LRYGB are largely(More)
In order to address the debatable prognostic role of MYC rearrangements in diffuse large B-cell lymphoma patients treated with rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone, we evaluated MYC rearrangements by fluorescence in situ hybridization in 563 cases using break-apart probes and IGH/MYC dual-fusion probes. Concurrent(More)
Angiogenesis is increased in B-cell chronic lymphocytic leukemia (B-CLL). We wanted to quantify and characterize the circulating endothelial cells (CECs) in patients with B-CLL and correlate with plasma angiogenesis-related factors. Using a four-color flow cytometry, we prospectively analyzed the CEC in the whole blood of 20 healthy controls and 20 patients(More)
BACKGROUND Cyclin D1 expression has been reported in a subset of patients with diffuse large B-cell leukemia (DLBCL), but studies have been few and generally small, and they have demonstrated no obvious clinical implications attributable to cyclin D1 expression. METHODS The authors reviewed 1435 patients who were diagnosed with DLBCL as part of the(More)
Abnormal expression of the chemokine receptor CXCR4 plays an essential role in tumor cell dissemination and disease progression. However, the significance of CXCR4 overexpression in de novo diffuse large B cell lymphoma (DLBCL) is unknown. In 743 patients with de novo diffuse large B cell lymphoma (DLBCL) who received standard Rituximab-CHOP(More)
PURPOSE Activated signal transducer and activator of transcription 3 (STAT3) regulates tumor growth, invasion, cell proliferation, angiogenesis, immune response, and survival. Data regarding expression of phosphorylated (activated) STAT3 in diffuse large B-cell lymphoma (DLBCL) and the impact of phosphorylated STAT3 (pSTAT3) on prognosis are limited. (More)
BACKGROUND To determine the prevalence of ascorbic acid deficiency in the surgical population, whether the body mass index (BMI) has an effect on ascorbic acid concentrations; and whether an association exists between ascorbic acid deficiency and adverse surgical outcomes. METHODS Preoperative plasma ascorbic acid concentrations were prospectively(More)
A 60-year-old woman presented to her primary care physician with fatigue and anemia. Laboratory evaluation revealed a hemoglobin level of 9.8 g/dL and an erythrocyte sedimentation rate (ESR) of 64 mm/hour. She subsequently developed nocturnal episodes of diaphoresis, confusion, and hypothermia. Capillary glucose measurements during the spells revealed(More)
Acute lymphoblastic leukemia with eosinophilia is a rare but distinctive clinical entity. The eosinophilia in these patients can present before, concomitantly, or after the diagnosis of leukemia. Patients with this syndrome often suffer from the cardiovascular complications of severe eosinophilia, suffering excess morbidity and mortality as a result of(More)
