BACKGROUND Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. METHODS Paraffin-embedded samples of(More)
AIM This work describes the human papillomavirus (HPV) prevalence and the HPV type distribution in a large series of vaginal intraepithelial neoplasia (VAIN) grades 2/3 and vaginal cancer worldwide. METHODS We analysed 189 VAIN 2/3 and 408 invasive vaginal cancer cases collected from 31 countries from 1986 to 2011. After histopathological evaluation of(More)
Cervical carcinoma is the most common malignant tumor among woman in Paraguay. Cytological screening programs have not been successful and a plan for human papillomavirus (HPV) based-screening program and/or vaccination is under evaluation. This study aimed to identify the contribution of HPV genotypes in invasive cervical cancer in Paraguay to provide(More)
Cervical cancer represents an important global public health problem. It is the 2nd most common cancer among women worldwide. Human Papillomavirus (HPV) infection is now well-established as a necessary cause of invasive cervical cancer (ICC) development. Only a few studies on HPV prevalence and type-specific distribution in ICC have been conducted in Italy.(More)
Exploring the presence and role of human papillomavirus (HPV) in head and neck cancer (HNC) is a necessary step to evaluate the potential impact of HPV prophylactic vaccines. To assess the prevalence and oncogenic role of HPV in HNC in Senegal. This is a multicenter cross-sectional study. Paraffin-embedded blocks of cases diagnosed with invasive HNC between(More)
The great interest in molecular epidemiology of human papilloma virus (HPV) in cervical cancer led us to perform a thorough evaluation of 2 polymerase chain reaction (PCR)-based methods for the detection of HPV in archival formalin-fixed paraffin-embedded (FFPE) samples. Thus, the aim of this study was to compare HPV detection in FFPE samples that have(More)
Anal condylomata are common in HIV-positive individuals and among men who have sex with men (MSM). Generally attributable to infection by low-risk human papillomaviruses (HPVs), condylomata are considered benign low-grade squamous intraepithelial lesions (SILs). However, anal condylomata have occasionally been linked to high-grade SIL and to oncogenic,(More)
OBJECTIVES To describe human papillomavirus (HPV) distribution in invasive cervical carcinoma (ICC) from Mali and Senegal and to compare type-specific relative contribution among sub-Saharan African (SSA) countries. METHODS A multicentric study was conducted to collect paraffin-embedded blocks of ICC. Polymerase chain reaction, DNA enzyme immunoassay and(More)
Eight HPV types (HPV26, 53, 66, 67, 68, 70, 73 and 82) that are phylogenetically closely related to 12 WHO-defined high-risk (HR) HPV have been rarely but consistently identified as single HPV infections in about 3% of cervical cancer (CxCa) tissues. Due to lack of biological data, these types are referred to as probable/possible (p) HR-HPV. To analyse(More)
OBJECTIVE To describe the HPV genotype distribution and to investigate the underlying secular trend in the relative contribution of HPV types 16-18 in invasive cervical cancer (ICC) over a period of 47 years (1958-2004) in South Korea. METHODS Paraffin embedded ICC samples were obtained from historical archives of two hospitals in Korea. HPV detection and(More)
