The ISCL/EORTC recommends revisions to the Mycosis Fungoides Cooperative Group classification and staging system for cutaneous T-cell lymphoma (CTCL). These revisions are made to incorporate advances related to tumor cell biology and diagnostic techniques as pertains to mycosis fungoides (MF) and Sézary syndrome (SS) since the 1979 publication of the(More)
The distribution, biochemical properties, and function of CD39 were characterized with the use of a new mAb termed 400. CD39 is an acidic (isoelectric point, approximately 4.2) glycoprotein of Mr approximately 78,000, containing approximately 24 kDa of N-linked oligosaccharide but no detectable O-linked sugars. CD39 was not expressed by resting blood T, B,(More)
As biotin-avidin systems continue to be developed for applications involving single cells, cell suspensions, and especially tissue sections, the need arises for a method of blocking endogenous avidin-binding activity. One such method is described and its proposed mechanism is discussed. Utilizing this method, endogenous avidin-binding activity was detected(More)
OBJECTIVES To determine the safety and efficacy of oral bexarotene (Targretin capsules; Ligand Pharmaceuticals Incorporated, San Diego, Calif). DESIGN The effects of 2 randomized doses of 6.5 mg/m(2) per day (with crossover for progression) vs 650 mg/m(2) per day (later modified to 300 mg/m(2) per day) were evaluated in an open-label, multicenter, phase 2(More)
Mycosis fungoides (MF) and Sézary syndrome (SS), the major forms of cutaneous T-cell lymphoma, have unique characteristics that distinguish them from other types of non-Hodgkin's lymphomas. Clinical trials in MF/SS have suffered from a lack of standardization in evaluation, staging, assessment, end points, and response criteria. Recently defined criteria(More)
Sézary syndrome (SS) has a poor prognosis and few guidelines for optimizing therapy. The US Cutaneous Lymphoma Consortium, to improve clinical care of patients with SS and encourage controlled clinical trials of promising treatments, undertook a review of the published literature on therapeutic options for SS. An overview of the immunopathogenesis and(More)
Human B lymphocyte subpopulations distinguished by their expression of the Leu-8 antigen were studied and found to differ in their respective maturational state and functional repertoire. The absence of Leu-8 expression correlated with an early step in antigen-driven B cell differentiation in that 1) as presented in the companion paper, germinal center B(More)
Melanoma cells can undergo self-destruction via programmed cell death, i.e. apoptosis. In these tumours, the molecular components of apoptosis include positive (apoptotic) and negative (anti-apoptotic) regulators. The former include p53, Bid, Noxa, PUMA, Bax, TNF, TRAIL, Fas/FasL, PITSLRE, interferons, and c-KIT/SCF. The latter include Bcl-2, Bcl-X(L),(More)
Melanoma accounts for only about 4% of all skin cancer cases but most of skin cancer-related deaths. Standard systemic therapies such as interferon (IFN) have not been adequately effective in the management of melanoma. Therefore, novel approaches are needed for prevention and treatment of this disease. Chemoprevention by naturally occurring agents present(More)
We used a gene amplification strategy to analyze T-cell receptor (TCR) gene rearrangements in 185 specimens, including mycosis fungoides/Sezary syndrome (MF/SS), other cutaneous neoplasms, inflammatory dermatoses, reactive lymphoid tissues, and normal skin. Genomic DNA was extracted from lesional tissues and rearrangements of the TCR-gamma chain gene were(More)
