Worldwide, cervical cancer ranks 4th in frequency in the female population, with about half of the cases being fatal. In Romania, it is the second type of cancer found in women, after breast cancer and the main cause of cancer mortality in patients aged between 15 and 44 years. The main cause of this type of cancer is human papilloma virus (HPV) infection. Although HPV is very widespread (> 85%), progression to cervical cancer is relatively rare. In countries that have implemented cervical screening programs, the incidence and mortality caused by this pathology have decreased by 50-75%. Also, the emergence of vaccines against the most common strains of oncogenic HPV and the implementation of vaccination programs will bring additional benefits in preventing cervical cancer. This paper presents the results of a retrospective study, performed on a number of 92 patients, which aimed to know the distribution of different HPV genotypes, their impact on the cervical epithelium, the degree of access to the national screening program, and openness to anti HPV vaccination.

Cervical cancer is the fourth most common cancer affecting women, with worldwide annual incidence and mortality rates of 528,000 and 266,000, respectively, according to the World Health Organization. It is well established that cervical cancer is predominantly caused by a persistent human papillomavirus (HPV) infection of cervical cells. Increasing numbers of studies have investigated HPV and cervical cancer, contributing greatly to the global knowledge and unraveling some of the critical questions regarding HPV transmission, infection, and prevention. However, despite these studies, our knowledge is far from complete and much remains to be discovered. Although molecular detection and HPV prophylactic approaches have greatly advanced in recent years, approximately 85% of the global burden of mortality from cervical cancer still occurs in developing countries. Clinical and molecular epidemiological studies have demonstrated a need for developing countries in general to adopt cervical screening and vaccination programs. However, studies examining cervical cancer screening modalities and HPV prevalence as well as whether HPV vaccination programs should be implemented are lacking at the national level in some developing countries. Therefore, this review describes the current status of HPV in developing countries, presenting some of the existing challenges in implementing cervical screening and HPV vaccination programs.

In sub-Saharan Africa (SSA), cervical cancer is a critical public health issue; it is the second leading cause of cancer among women and the leading cause of female cancer deaths. Incidence and mortality rates are substantially higher than in high-income countries with population-based screening programs, yet implementing screening programs in SSA has so far proven to be challenging due to financial, logistical and sociocultural factors. Human Papillomavirus (HPV) vaccination is an effective approach for primary prevention of cervical cancer and presents an opportunity to reduce the burden from cervical cancer in SSA. With a number of SSA countries now eligible for GAVI support for vaccine introduction, it is timely to consider the factors that impede and facilitate implementation of vaccine programs in SSA. This article reviews the epidemiological and clinical features of cervical cancer in SSA and describes the current status of HPV vaccine implementation in SSA countries. The review considers the challenges that will need to be addressed, and effective approaches to the design and implementation of HPV vaccination programs, using Rwanda as a case study. The review aims to provide suggestions and guidance to those involved in the development and implementation of HPV vaccination programs in SSA.

Cervical cancer (CC) has a high incidence and mortality and is accompanied by lack of organized CC screening programs, lack of health-care facilities, and a lack of human papillomavirus (HPV) vaccination among female population in the world, particularly China. We recruited 487 females who visited the outpatient department of the First People’s Hospital of Yunnan Province from November 2015 to January 2016 to complete a standardized-designed questionnaire. We found that only 39.6% of the females knew about the role of HPVs in the development of cervical cancer. Moreover, none of the females knew that HPV could cause penile carcinomas, perianal carcinomas, and head and neck carcinomas. The majority of the participants acquired information about cervical cancer, HPV, and the HPV vaccine from medical workers. Only 15.6% of the recruited females had heard about the HPV vaccine. The overall HPV vaccine acceptance rate was higher (91.2%) if the vaccine was available free of cost. In this study, we found high acceptability of the HPV vaccine in Chinese women and high awareness about cervical cancer. However, very low levels of knowledge about HPVs and their role in cancer development among the recruited women is alarming. Therefore, it is very important to initiate educational programs to raise awareness and knowledge about cervical cancer, HPV, and the HPV vaccine in this region.

e17520 Background: Cervical cancer (CC) is the most common gynecological cancer in Kazakhstan (KZ). Standardized incidence rate of CC was 16.7 per 100, 000, while the mortality rate was 5, 9 per 100, 000, in 2020. The National Cervical Screening program in KZ uses cytology (Pap test) from 2008, which is free of charge for women aged 30 to 70 years of age with an interval of 4 years. In 2017 Experts from ImPact Mission and analyzed existing CC screening revealed a number of recommendations aimed at reducing the screening interval and increasing the coverage. The purpose of this study was to analyze results of CC screening in KZ and his impact on CC incidence and mortality. Methods: Coverage, the number of screened women, the level of pre-cancer detection and cervical cancer during screening have been obtained from specific reports (form № 025, № 08) for 2008-2020. Results: The total number of screened women for 2008 were 554 283 women. There is a decrease in screening coverage to 45.9% in 2017 due to a decrease in funding. in this regard, in 2017, a number of changes were made to the existing screening program. In 2020 after the CC screening improvement 786 690 women were examined during the screening program, coverage rate was 66, 2%, . Analysis of screening results showed a marked increase in the detection of precancerous lesion from 0, 136 in 2008 to 0, 87 with an increasing by 37%. The analysis of CC incidence revealed significant changes: after the introduction of screening, an increase in the incidence rate is noted from 15.5 in 2008 to 20.1 per 100, 000 female population in 2015. Since 2015, there has been a significant decrease to 16.7 per 100, 000 women. Conclusions: Despite the positive results of screening, an increse the screening coverage, improvement in the detection of the initial stage of CC, mortality rate from CC and a one-year mortality remain high, which makes it necessary to improve the screening of CC in KZ through the introduction of HPV-screening

Human papillomavirus (HPV) causes cervical cancer, which is the fourth most common cancer in women. Most of the cervical cancers are linked to genital infection with HPV and it is the most common viral infection of the reproductive tract. At present, there are three types of HPV vaccines available. Even though HPV vaccination is a primary prevention tool, that does not eliminate the need for routine cervical screening, since the vaccines do not protect against all high-risk HPV types. Ninety percent of HPV infections have no clinical consequences at all whether they are high-risk or low-risk subtypes of HPV. All three types of HPV vaccines have very high vaccine efficacy for prevention of HPV infection among females aged 14 to 26 years. Proper assessment of the safety of HPV vaccine is a problem even after proper systematic review since the most of the clinical trials on the safety of the vaccines were used Hepatitis A vaccine or high immunogenicity enhancing aluminium adjuvant as their placebo. HPV vaccination would be very cost effective for the countries when there is no cervical screening program or if the programme coverage is very poor.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.329-336

Viral infections contribute as a cause of 15–20% of all human cancers. Infection by oncogenic viruses can promote different stages of carcinogenesis. Among many types of HPV, around 15 are linked to cancer. In spite of effective screening methods, cervical cancer continues to be a major public health problem. There are wide differences in cervical cancer incidence and mortality by geographic region. In addition, the age-specific HPV prevalence varies widely across different populations and showed two peaks of HPV positivity in younger and older women. There have been many studies worldwide on the epidemiology of HPV infection and oncogenic properties due to different HPV genotypes. However, there are still many countries where the population-based prevalence has not yet been identified. Moreover, cervical cancer screening strategies are different between countries. Organized cervical screening programs are potentially more effective than opportunistic screening programs. Nevertheless, screening programs have consistently been associated with a reduction in cervical cancer incidence and mortality. Developed countries have achieved such reduced incidence and mortality from cervical cancer over the past 40 years. This is largely due to the implementation of organized cytological screening and vaccination programs. HPV vaccines are very effective at preventing infection and diseases related to the vaccine-specific genotypes in women with no evidence of past or current HPV infection. In spite of the successful implementation of the HPV vaccination program in many countries all over the world, problems related to HPV prevention and treatment of the related diseases will continue to persist in developing and underdeveloped countries.

High-risk human papillomavirus strains are widely known to be the causative agents responsible for cervical cancer development. Aggregated damage caused by papillomaviruses solely is estimated in at least 5% of all malignancies of the human body and 16% in cancers that affect the female genital area. Enhanced understanding of the complex issue on how the high extent of carcinogenicity is eventually formed due to the infection by the Papoviridae family would contribute to enhancing current prevention strategies not only towards cervical cancer, but also other HPV associated cancers. This review article is aimed at presenting the key points in two directions: the current cervical cancer prevention and related aspects of HPV behavior. Virtually all applied technologies related to HPV diagnostics and screening programs, such as HPV tests, colposcopy-based tests (VIA/VILI), conventional and liquid-based cytology, currently available are presented. Issues of availability, advantages, and drawbacks of the screening programs, as well as vaccination strategies, are also reviewed in the article based on the analyzed sources. The current point of view regarding HPV is discussed with emphasis on the most problematic aspect of the HPV family concerning the observed increasing number of highly carcinogenic types. Present trends in HPV infection diagnostics throughout the human fluids and tissues are also reported, including the latest novelties in this field, such as HPV assay/self-sample device combinations. Besides, a brief outline of the related prevention issues in Kazakhstan, the leading country of Central Asia, is presented. Kazakhstan, as one of the post-soviet middle-income countries, may serve as an example of the current situation in those terrains, concerning the implementation of globally accepted cervical cancer prevention strategies. Along with positive achievements, such as the development of a nationwide screening program, a range of drawbacks is also analyzed and discussed.

"The study aims to compare different screening methods that are currently being used to confirm a cervical intraepithelial lesion (CIN) underlying the inherent advantages of the varied examination procedures. In this study we are looking at the quality contrast of the different paraclinical examinations relative to the cost, invasiveness and cultural acceptance of such procedures. Every year, more than 100,000 women in EU countries are diagnosed with cervix uteri cancers (CCU). This type of cancer can be prevented if precancerous cells are detected and treated. HPV is found in over 90% of cervix uteri cancers. In Europe, more than half of the countries have implemented screening programs for cervical cancer, and most European countries now have national HPV vaccination programs, however target populations vary depending on the epidemiological evidence and the budgetary level of each countries health system. In this study we evaluated and compared the current and modern techniques used for cervix cellular diagnostics. Also, this study helps improve the understanding on the economic and social implications of screening among female population and the impact it has on healthcare system relieving. Romania recorded an incidence of 22.6 cases of cervix uteri cancers / 100.000 women (age standardized rate), and a mortality of 9.6 / 100.000, ranking second highest in the EU zone."


Cervical neoplasia provides an overview of the 4th most common malignancy in women worldwide, including the premalignant phase. Specific terminology used in cytology and histology (including atypia, dyskaryosis, cervical intraepithelial neoplasia (CIN), cervical glandular intraepithelial neoplasia (CGIN) and invasive cervical cancer (ICC) are explained, and the epidemiology and risk factors (with an emphasis on human papilloma virus (HPV)) for this common malignancy are included. Clinical presentation is outlined. Cervical screening is discussed, including the role of HPV testing, and both the British Association for Cytopathology/NHS cervical screening program 2013 classification of cervical cytology and the Bethesda system (used more widely worldwide) are explained. Diagnosis includes colposcopic examination of the cervix, and the management of both CIN and cervical cancer are included. HPV vaccination, pregnancy, and women living with HIV (including ICC as AIDS-defining) are discussed.

Cervical cancer is a critical public health issue in sub-Saharan Africa (SSA), where it is the second leading cause of cancer among women and the leading cause of female cancer deaths. Incidence and mortality rates are substantially higher than in high-income countries with population-based screening programs, yet implementing screening programs in SSA has so far proven to be challenging due to financial, logistical, and sociocultural factors. Human Papillomavirus (HPV) vaccination is an effective approach for primary prevention of cervical cancer and presents an opportunity to reduce the burden from cervical cancer in SSA. With a number of SSA countries now eligible for Global Alliance for Vaccines and Immunization (GAVI) support for vaccine introduction, it is timely to consider the factors that impede and facilitate implementation of vaccine programs in SSA. This article describes epidemiological features of cervical cancer in SSA and the current status of HPV vaccine implementation in SSA countries. Rwanda’s experience of achieving high vaccination coverage in their national HPV immunization program is used as a case study to explore effective approaches to the design and implementation of HPV vaccination programs in SSA. Key factors in Rwanda’s successful implementation included government ownership and support for the program, school-based delivery, social mobilization, and strategies for reaching out-of-school girls. These findings might usefully be applied to other SSA countries planning for HPV vaccination.
