We identified 18 patients with the distinct clinical phenotype of susceptibility to disseminated nontuberculous mycobacterial infections, viral infections, especially with human papillomaviruses, and fungal infections, primarily histoplasmosis, and molds. This syndrome typically had its onset in adulthood (age range, 7-60 years; mean, 31.1 years; median, 32(More)
The importance of alpha beta versus gamma delta T-cell subset antigen expression in the classification of peripheral T-cell lymphomas is still unclear. The objective of this study was to investigate the prognostic value of T-cell receptor-delta 1 (TCR delta 1) expression in primary cutaneous T-cell lymphomas. TCR delta 1 cellular expression was assessed in(More)
From 1992 to 2000, we identified 23 lymph node biopsies with focal germinal centers (GCs) containing centrocytes staining strongly for bcl-2 protein, whereas most of the remaining lymph node showed bcl-2-negative follicular hyperplasia. We propose the designation in situ localization of follicular lymphoma (FL) for this phenomenon. In 2 additional cases,(More)
p27 is a cyclin-dependent kinase inhibitor that plays a critical role in regulating G(1)/S progression, and whose activity is, in part, regulated through interactions with D-type cyclins. Mantle cell lymphoma (MCL) is characterized by the t(11;14) translocation resulting in deregulated cyclin D1. We previously showed that p27 expression in MCL, as assessed(More)
BACKGROUND The mission of the National Cancer Institute's Early Detection Research Network (EDRN) is to identify and validate cancer biomarkers for clinical use. Since its inception, EDRN investigators have learned a great deal about the process of validating biomarkers for clinical use. Translational research requires a broad spectrum of research(More)
Follicular lymphoma (FL) is a low-grade lymphoma that typically lacks CD5 antigen expression. We report 3 cases of FL with unusual expression of CD5. All cases showed histologic features of FL, including effaced nodal architecture, follicular growth pattern, and a spectrum of grades from 1 to 3 using World Health Organization criteria. In flow cytometric(More)
Cladribine induces long-term complete remission in hairy cell leukemia (HCL) patients but does not clear minimal residual disease (MRD) according to high-sensitivity PCR assays. To quantify MRD in patients after anti-CD22 recombinant immunotoxin BL22 and other agents, we used a relative quantitative PCR (RQ-PCR) assay using a primer and probe, both patient(More)
We have developed a system to isolate rare cells from whole blood using commercially available components and simple microfluidics. We characterized the capture of MCF-7 cells spiked into whole human blood using this system to demonstrate that enrichment and enumeration studies give results similar to in situ surface-modified devices while reducing(More)
