Infections caused by high-risk human papillomavirus (HPV) are responsible for 7.7% of cancers in developing countries, mainly cervical cancer. This disease is steadily increasing in sub-Saharan Africa, with more than 75,000 new cases and 50,000 deaths yearly, further increased by HIV infection. Areas covered: The current status of cervical cancer associated with HPV in sub-Saharan Africa has been systematically revised. The main issues discussed here are related to the public health burden of cervical cancer in sub-Saharan Africa and predictions for the coming decades, including molecular epidemiology and determinants of HPV infection in Africa, and promising prevention measures currently being evaluated in Africa...

BACKGROUND: Over 85% of cervical cancer cases and deaths occur in developing countries. HIV-seropositive women are more likely to develop precancerous lesions that lead to cervical cancer than HIV-negative women. However, the literature on cervical cancer prevention in seropositive women in developing countries has not been reviewed. The aim of this study is to systematically review cervical cancer prevention modalities available for HIV-seropositive women in developing countries. METHODS/DESIGN: This protocol was developed by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement, and the systematic review will be reported in accordance with the PRISMA guidelines...

Human papillomavirus (HPV)-driven oropharyngeal cancers (OPCs) represent an increasing proportion of head and neck cancers that could become, in the next few decades, a public health problem in certain western countries. This significant epidemiological change strongly calls for preventive measures. Prophylactic HPV vaccination and screening programmes for early identification and treatment of premalignant lesions are currently being used to reduce the incidence of uterine cervical cancer, which is the paradigm of HPV-driven malignancy...

Cervical cancer is the second most common cancer and the third leading cause of cancer death in females worldwide, especially in developing countries. High risk human papillomavirus (HR-HPV) infection causes cervical cancer and precancerous cervical intraepithelial neoplasia (CIN). Integration of the HR-HPV genome into the host chromatin is an important step in cervical carcinogenesis. The detection of integrated papillomavirus sequences-PCR (DIPS-PCR) allowed us to explore HPV integration in the human genome and to determine the pattern of this integration...

Highly oncogenic human papillomavirus (HPV) infections are responsible for 7.7 % of cancers in developing countries, mainly cervical cancer. The incidence of this emerging cancer is steadily increasing in sub-Saharan Africa, with more than 75,000 new cases and close to 50,000 deaths a year, a toll further increased by HIV infection. According to the World Health Organization, cervical cancer will kill more than 443,000 women per year worldwide by 2030, nearly 90 % of them in sub-Saharan Africa. This increase in cervical cancer incidence in Africa is now counteracting the progress made by African women in reducing maternal mortality and increasing longevity...

Clinical practice guidelines for gynecologic cancers have been developed by academic society from several countries. Each guideline reflected their own insurance system and unique medical environment, based on the published evidence. The Korean Society of Gynecologic Oncology (KSGO) published the first edition of practice guidelines for gynecologic cancer treatment in late 2006; the second edition was released in July 2010 as an evidence-based recommendation. The Guidelines Revision Committee was established in 2015 and decided to develop the third edition of the guidelines in an advanced format based on evidence-based medicine, embracing up-to-date clinical trials and qualified Korean data...

Cervical cancer is considered to be a major health problem for women in developing countries, but it is also problematic for more developed countries as global migration increases and health behaviors move from the countries of origin to new places of residence. We designed and produced a testimonial video and a fotonovela (printed short story) to educate women about cervical cancer and screening. The development of the materials included formative research, production, pretesting, dissemination, and evaluation...

HPV is the cause of almost all cervical cancer and is responsible for a substantial fraction of other anogenital cancer and oropharyngeal cancer. Understanding the HPV-attributable cancer burden can boost programs of HPV vaccination and HPV-based cervical screening. Attributable fractions (AF) and the relative contributions of different HPV types were derived from published studies reporting on the prevalence of transforming HPV infection in cancer tissue. Maps of age-standardized incidence rates of HPV-attributable cancers by country from GLOBOCAN 2012 data are shown separately for the cervix, other anogenital tract, and head and neck cancers...

OBJECTIVE: Different types of vaginal fistulas is a relatively uncommon condition in the Western world but very frequent in developing countries. In the past, conventional vaginography was the radiological examination of choice for exploring this condition. CT and MRI are now both used for this purpose. Our objective was to test the feasibility and to explore the potential role of a new CT imaging technique implementing vaginal introitus obstruction and opacification of the vagina with iodine contrast agent, to show patency of a fistula...

Human papillomavirus (HPV) causes greater than 5% of cancers worldwide, including all cervical cancers and an alarmingly increasing proportion of oropharyngeal cancers (OPCs). Despite markedly reduced cervical cancer incidence in industrialized nations with organized screening programs, cervical cancer remains the second most common cause of death from cancer in women worldwide, as developing countries lack resources for universal, high-quality screening. In the United States, HPV-related OPC is only 1 of 5 cancers with a rising incidence since 1975 and now has taken over the cervix as the most common site of HPV-related cancer...

Cervical cancer is the third highest cause of death in developing countries and most commonly results from high‑risk human papillomavirus (HR‑HPV) infection. Among HR‑HPV genotypes, HPV16 and HPV18 are the most prevalent in cervical cancers. Therefore, the present study aimed to develop a detection assay for HPV16 and HPV18 infection using loop‑mediated isothermal amplification (LAMP) with lateral flow dipstick (LFD) tests. This assay is a simplified, user‑friendly method for the visual detection of HPV genotypes...

BACKGROUND: Cervical cancer is one of the major diseases that affect women of child bearing age. Its main cause is the human papilloma virus; although, other associated factors have been evidenced to increase its risk. Pap-smear screening and vaccination which has been shown to be successful in reducing the incidence and prevalence of the disease in developed countries, has been neglected in developing countries due to lack of knowledge, misconceptions, and cultural beliefs. MATERIALS AND METHODS: A cross-sectional study involving only female Sub-Saharan Africa (SSA) students in a UK university setting...

The incidence of cervical cancer in low- and middle-income countries (LMICs) is five times higher than that observed in high-income countries (HICs). This discrepancy is largely attributed to the implementation of cytology-based screening programmes in HICs. However, due to reduced health system infrastructure requirements, HPV testing (self- and provider-collected) and visual inspection with acetic acid (VIA) have been proposed as alternatives that may be better suited to LMICs. Knowing the relative value of different screening options can inform policy and the development of sustainable prevention programs...
