Human papillomavirus (HPV) cofactors for cervical cancer include smoking, multiparity, and oral contraceptive use, but their mechanisms of action are not fully understood. It is also unknown whether cofactors vary by HPV genotypes. The Study to Understand Cervical Cancer Early Endpoints and Determinants (SUCCEED) is a cross-sectional study comprising women(More)
PURPOSE Cytology-based screening has limited sensitivity to detect prevalent cervical precancers. Human papilloma virus (HPV) DNA testing is highly sensitive and provides a high, long-term reassurance of low risk of cervical cancer. However, the specificity of HPV DNA testing is limited, requiring additional, more disease-specific markers for efficient(More)
Human papillomaviruses (HPVs) are described as "types" based on their genome sequences and identified by a number. For example, HPV-6 is associated with genital warts, and HPV-16 with anogenital cancers. The genomes of many HPV types have been reisolated, sequenced and compared to reference "prototypes" countless times by laboratories throughout the world.(More)
Variations in biological behavior suggest that each carcinogenic human papillomavirus (HPV) type should be considered individually in etiologic studies. HPV genotyping assays might have clinical applications if they are approved for use by the FDA. A widely used genotyping assay is the Roche Linear Array HPV genotyping test (LA). We used LA to genotype the(More)
Many studies have established a critical role for human papillomavirus (HPV) in the development of anogenital squamous neoplasia. In this report, we show the distribution of 37 high- and low-risk HPV types in 116 cases of invasive squamous vulvar carcinoma. Sections from paraffin-embedded tissue blocks were dissected as necessary to select areas of invasive(More)
OBJECTIVE Chromosomal gains at 3q26, 5p15 and 20q13 have been described in cervical precancer and cancer. We evaluated a novel fluorescence in situ hybridization (FISH) assay that detects gains at these three loci simultaneously as a possible biomarker for detecting cervical precancer. METHODS Chromosomal copy numbers at 3q26, 5p15, 20q13 and the(More)
BACKGROUND Phyllodes tumors (PTs) represent uncommon fibroepithelial lesions of the breast that express c-Kit and platelet-derived growth factor receptor-alpha, similar to gastrointestinal stromal tumors (GISTs). 'Activating' mutations in these genes underlie responsiveness of GISTs to imatinib. Standard treatment for breast PTs is wide local excision, with(More)
The Bethesda system for standardized reporting of thyroid fine needle aspiration (FNA) cytology has positively affected the clarity of communication of results and management of patients evaluated for thyroid nodules. Problematic areas still exist in the triage of some of these samples, particularly those in the categories of "follicular lesion with atypia(More)
Among the more than one hundred formally described human papillomavirus (HPV) types, 18 are referred to as high-risk HPV types due to their association with anogenital cancer. Despite pathogenic similarities, these types form three remotely related taxonomic groups. One of these groups is called HPV species 9 and is formed by HPV-16, the most common and(More)
Among more than 200 human papillomavirus (HPV) types presumed to exist, 18 "high-risk" HPV types are frequently found in anogenital cancer. The best studied types are HPV-16 and 18, which are only distantly related to one another and form two separate phylogenetic branches, each including six closely related types. HPV-30, 53, 56, and 66 form a third(More)
