A potential benefit of profiling of tissue samples using microarrays is the generation of molecular fingerprints that will define subtypes of disease. Hierarchical clustering has been the primary analytical tool used to define disease subtypes from microarray experiments in cancer settings. Assessing cluster reliability poses a major complication in(More)
PURPOSE This multicenter randomized trial was designed to test whether melanoma-associated helper peptides augment CD8(+) T-cell responses to a melanoma vaccine and whether cyclophosphamide (CY) pretreatment augments CD4(+) or CD8(+) T-cell responses to that vaccine. PATIENTS AND METHODS In all, 167 eligible patients with resected stage IIB to IV melanoma(More)
OBJECTIVE To compare the performance of radical cystectomy with ileal conduit diversion by standard methods with that using the assistance of the daVinci robotic system (Intuitive Surgical, Sunnyvale, CA, USA). PATIENTS AND METHODS From November 2003 to August 2005, we performed 30 radical cystectomies with ileal conduit urinary diversions on patients(More)
OBJECTIVE This retrospective study systematically compared mammographic density with histology in women receiving or not receiving menopausal hormone therapy (HT). DESIGN This study was approved by the institutional review board. Twenty-eight postmenopausal women using HT were matched with 28 postmenopausal women not using HT at the time of breast cancer(More)
Immune cells infiltrating the microenvironment of melanoma metastases may either limit or promote tumor progression, but the characteristics that distinguish these effects are obscure. In this study, we systematically evaluated the composition and organization of immune cells that infiltrated melanoma metastases in human patients. Three histologic patterns(More)
Burkholderia cenocepacia is an opportunistic pathogen that can cause severe lung infections in cystic fibrosis patients. To understand the contribution of B. cenocepacia flagella to infection, a strain mutated in the major flagellin subunit, fliCII, was constructed in B. cenocepacia K56-2 and tested in a murine agar bead model of lung infection. C57/BL6(More)
Signal transduction occurs by the reversible assembly of oligomeric protein complexes that include both enzymatic proteins and proteins without known enzymatic activity. These nonenzymatic components can serve as scaffolds or anchors and regulate the efficiency, specificity, and localization of the signaling pathway. Here we report the identification of(More)
RATIONALE AND OBJECTIVES Quantitative criteria for the Breast Imaging Reporting and Data System (BI-RADS) mammographic density categories have recently been defined as <25% dense for almost entirely fatty, 25%-50% dense for scattered fibroglandular densities, 51%-75% for heterogeneously dense, and >75% dense for the extremely dense category. The purpose of(More)
PURPOSE Human melanoma cells express shared antigens recognized by CD8(+) T lymphocytes, the most common of which are melanocytic differentiation proteins and cancer-testis antigens. However, peptide vaccines for melanoma usually target only one or two MHC class I-associated peptide antigens. Because melanomas commonly evade immune recognition by selective(More)
Melanoma vaccines have not been optimized. Adjuvants are added to activate dendritic cells (DCs) and to induce a favourable immunologic milieu, however, little is known about their cellular and molecular effects in human skin. We hypothesized that a vaccine in incomplete Freund's adjuvant (IFA) would increase dermal Th1 and Tc1-lymphocytes and mature DCs,(More)
