In the last decade, the inclusion of HPV DNA testing in cervical cancer screening has provided one of the best strategies for the prevention and timely detection of HPV. We conducted a high-throughput HPV genotyping study based on MALDI-TOF mass spectrometry to determine the prevalence of 24 HPV genotypes, including oncogenic genotypes, in Mexican women and correlated the results with cytological findings and clinical variables. We likewise identified the risk factors in patients with the HPV infection. Our study included 1000 women from Sonora, Mexico, who participated in cervical cancer screening campaigns and who underwent a Pap smear and HPV DNA test. The results showed that the overall prevalence of HPV was 27.2%, 18.5% with single, and 8.7% multiple infections. The low-risk HPV genotype 6 (8.5%) and oncogenic genotypes 31 (8.1%) and 53 (4.4%) were the most prevalent in the study population. The number of lifetime sexual partners, previous STIs, and age at first intercourse was significantly associated with HPV infection ( P ≤ 0.05). Smoking (OR = 1.5609; 95% IC 1.062–2.292) and more than three lifetime sexual partners (OR = 1.609; 95% IC = 1.124–2.303) represented risk factors for HPV infection. Cytological abnormalities were found in 3.4% of the HPV-positive samples. CIN 1–3 occurred in 0.6% of high-risk HPV cases. In general, the prevalence of the HPV genotypes is high in Mexican women with normal cytological findings. This issue highlights the importance of HPV research in seemingly healthy women and could help guide screening strategies for cervical cancer prevention in Mexico. Impact statement We are submitting data regarding the prevalence and type distribution of the HPV infection and the risk factors associated with it, which may provide a valuable reference to reinforce screening strategies, and to maintain HPV genotype surveillance in Mexico. We discuss the overall prevalence of HPV infection as detected in normal cytological samples stratified by age, different types of infection, and oncogenic capacity. One of the most important findings was that common HPV genotypes detected in healthy women were the genotype numbers: 6, 31, 16, and 56, likewise, smoking and having a history of more than three sexual partners over their lifetime, represented the main risk factors in this study. Furthermore, we found a low frequency of cytological abnormalities and CIN 1–3 in women with HR-HPV.

Screening Strategies

Cervical cancer is the most common cancer among women in many developing countries constituting 20%-30% of female cancers. The etiological factors of cervical cancer include environmental, social, sexual and sexually transmitted agents including human papilloma virus (HPV). HPV has identified in 99.7% invasive cancer. Objective of the study was to find out the prevalence of HPV-DNA virus among diagnosed cases of preinvasive and invasive diseases and to find out different sociodemographic parameters related to carcinoma cervix. This was a cross sectional study. The study has conducted in the department of Obstetrics and Gynaecology of Bangabandhu Sheikh Mujib Medical University. Duration of study was from May 2005 to May 2006. Samples were collected from diagnosed cases of CIN I, II, III and CIS and invasive cancer. Thirty cases were recruited for collection of cervical scraping. Sample were collected of in a specially designed sampler containing liquid transport medium and preserved in minus 20 Degree Celsius and sent to the DNA laboratory for processing and identification of HPV by hybrid capture II method. The results were analyzed by using SPSS version 11.0 and shown in tables and diagrams. The risk factors for HPV infection identified from the result. These are early sexual activity, years of sexual activity, urban people, and higher number of pregnancies. The test could identify HPV-DNA in 100 % of invasive and 50 % of preinvasive cancer. In this study HPV infection was found as a strong determinant for the development of cervical carcinoma and its precursors. Poor socio-economic condition, lower level of education, early marriage and first delivery, multi-parity, years of sexual activity are the risk factors for developing HPV infection. New guidelines for cervical cancer screening strategies could be able to develop from the information obtained from this study. A population-based study with larger sample will be required for the evaluation of cervical cancer screening strategies.

Objectives We conducted a study to investigate the prevalence of human papillomavirus (HPV) infections in an opportunistic sample of women in Manitoba, Canada. We inquired about risk factors associated with HPV infections and linked the HPV typing results with the cervical cancer screening history of the participants. Methods The study population included 592 women attending Papanicolaou (Pap) test clinics. After signing a consent form, participants were given a self-administered questionnaire on risk factors and received a conventional Pap test. Residual cells from the Pap tests were collected and sent for HPV typing. Results The mean age of the population was 43 years. A total of 115 participants (19.4%) had an HPV infection, 89 of whom had a normal Pap test. Of those who were HPV-positive, 61 (10.3%) had high-risk (Group 1) HPV. HPV-16 was the most prevalent type (15/115: 13.0% of infections). The most consistent risk factors for HPV infection were young age, Aboriginal ethnicity, higher lifetime number of sexual partners and higher number of sexual partners in the previous year. Conclusion The prevalence of HPV types in Manitoba is consistent with the distributions reported in other jurisdictions. These data provide baseline information on type-specific HPV prevalence in an unvaccinated population and can be useful in evaluating the effectiveness of the HPV immunization program. An added benefit is in the validation of a proof of concept which links a population-based Pap registry to laboratory test results and a risk behaviour survey to assess early and late outcomes of HPV infection. This methodology could be applied to other jurisdictions across Canada where such capacities exist.

ABSTRACT: Introduction: Human papillomavirus (HPV) is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. Objectives: In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. Methods: Routine cervical samples were analyzed using Linear Array(r) HPV Genotyping test (Roche). Results: A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%). Of these samples, 604 (38.20%) were positive for a single HPV genotype, while another 85 (5.37%) samples were positive for multiple HPV types. Genotype 16 (5.50%) resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55%) and HPV 11 (3.80%) occupied the second and the third place in frequency among all detected genotypes. Conclusions: Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

Human papilloma virus is an oncogenic DNA virus, which is identified in 99.7% case of invasive cancer. It is the most prevalent virus involved in sexually transmitted diseases worldwide and an important public health challenge for the prevention of cervical carcinoma. Cervical cancer is the second cause of malignant neoplasia and death in women. The present study was thus designed to detect the risk factors for HPV infection in normal and unhealthy cervix of women attending tertiary care hospital (BSMMU). HPV DNA was detected among the study population using the Hybrid Capture 2 assay, which determined HPV high risk types. A total of 68 women between 25-70 years of age were included in this cross sectional study. Among them 13 (19.1%) cases were tested positive for HPV DNA. The risk factors for HPV infection identified from this result are early sexual activity, lower level of education, early marriage, multi-parity, total duration of sexual activity in years and long term use of oral contraceptive pill and poor socioeconomic condition. Increased awareness and understanding regarding HPV infection would improve the risk of infection and control in sexually active women. HPV diagnosis at early stages of infection is of fundamental importance. The use of HPV test in routine cervical mass screening may not be possible in developing countries like Bangladesh due to its high cost. Nevertheless, it has been shown to be a useful tool when combined with cytology to diagnose high-risk infection in apparently normal tissues, and may help to reduce the risk of cervical cancers. The results obtained from this study ultimately contribute to cervical cancer prevention among Bangladeshi women. DOI: http://dx.doi.org/10.3329/bmjk.v46i1-2.18231 Bang Med J (Khulna) 2013; 46 : 3-6

Objective: This study sought to identify the presence of HPV infection and the risk factors related to susceptibility to cervical cancer in asymptomatic women. Methods: It is a cross-sectional study with 428 users attended Basic Health Units, in Arapiraca, Alagoas, Brazil. Sociodemographic, behavioral variables, and cytopathological reports were collected. Molecular detection of the HPV virus was performed by Nested-PCR. Statistical analysis was conducted with SPSS version 22.0. Results: A total of 428 women were studied, HPV DNA detected in 39.2% (n = 168), with a mean age of 41 years old. There was an association of HPV with use of oral contraceptives (p <0.016) and alcoholism (p <0.038). It was showed a higher frequency of positive HPV in women older than 25 years old (88.7%), up to 5 sexual partners (93.4%), up to 3 pregnancies (71.4%), and with the cytopathologic results within the limits of normality (61.9%). HPV was identified in 40.3% (104/258) of the women with results within the limits of normality. Conclusion: Our results suggest that the use of oral contraceptives and alcoholism may be considered as possible risk factors related to cervical oncogenesis. With this, it is necessary to propose interventions aimed at the health education of this population, actions of prevention, and early detection.

Abstract Background Human Papilloma Virus (HPV) genotypes concordance among sexual couples has been evaluated in many investigations with considerable variations in the concordance. However, no such study has carried out between Iranian couples yet. Methods Urogenital specimen from both males and females of couples were taken and transferred to Nilou laboratory for molecular analysis. HPV DNA extraction and typing were carried out using cobas 4800 platform. Demographic and virological data were analyzed afterwards. Results One hundred fourteen couples were enrolled in the study. The mean age of participants were 36 ± 8 and 32 ± 7 for males and females, respectively. 64 (28%) of specimens were positive for at least one HPV genotype. The positive rates within genders were 30.7 and 25.4% for females and males, respectively with a considerable association (P value 0.021). Within the positive samples, 13(5.7%), 8 (7%) and 31(13.5%) were belonged to 16, 18 and other HR genotypes. 59 (51.8%) couples who were negative for HPV showed negative concordance. Of the total positive HPV patients (55 couples, 48.2%), 9 (16.3%) couples had positive concordance and the rest of 46 (83.7%) couples (either of spouse being negative and the other being positive for HPV) showed neither kinds of concordance. Conclusion Recognition of the dynamics of HPV infection not only in women, but in their sexual partners could impact the implementation of preventive measures like HPV vaccination for cervical cancer and other HPV-related diseases for both sexual partners.

Abstract Background Screening of unvaccinated women remains essential to mitigate the high morbidity/mortality of cervical cancer. Here, we compared visual inspection with acetic acid (VIA), recommended by WHO as the most cost-effective screening approach in LMICs, with HPV-based screening, and usage of p16INK4a/Ki-67 dual stain cytology. Methods We prospectively enrolled women participating in a VIA-based cervical cancer screening program in two peri-urban health centers of Kenya. Consenting women had a VIA examination preceded by collection of a liquid-based cytology sample from the cervix stored in PreservCyt medium (Hologic®). Analysis of all samples included a hrHPV DNA test and evaluation of a p16INK4a /Ki-67 (CINtecPLUS®) dual stained slide that was prepared using the ThinPrep® 2000 Processor and evaluated by a pathologist trained in the methodology. Results In 701 of a total of 800 women aged 18–64 years, all three investigations were performed and data could be analyzed. The HPV, VIA and dual stain cytology positivity were 33%, 7%, and 2% respectively. The HPV positivity rate of VIA positive cases was 32%. The five most common HPV types were HPV16, 52, 68, 58 and 35. The OR among HIV infected women of an HPV infection, VIA positivity and positive dual stain cytology were 2.6 (95%CI 1.5–4.3), 1.9 (95%CI 0.89–4.4) and 3.4 (95%CI 1.07–10.9) respectively. The sensitivity of VIA to detect a p16INK4a/Ki-67 positive transforming infection was 13% (95%CI 2–38). Conclusions Primary HPV testing appears feasible and should be considered as a primary screening test also in LMICs. The poor sensitivity of VIA renders it unsuitable as a triage test for HPV positive women. The utility of p16INK4a/Ki-67 dual stain cytology as a triage test for HPV positive women in LMICs should be further studied.

Abstract The article provides a review of literature on risk factors and cofactors for cervical cancer and barriers to cervical cancer screening. Cofactors of cervical cancer are risk factors that contribute to the development of cervical cancer but are not able to generate cancer on their own. Risk factors and cofactors of cervical cancer have been clearly identified in many studies. Therefore cervical cancer is a preventable type of cancer. The aim of this article was to describe in more detail the barriers to cervical cancer screening among women all over the world. The barriers to cervical cancer screening can be sorted according to the results of studies into five main groups: informational, psychological, socio-economic, behavioral and cultural, and geographical. Efforts to reduce risk factors and cofactors of HPV infection and cervical cancer and to increase knowledge about screening are necessary in a positive approach to preventing cervical cancer in society and to promote women’s health.

Objective: Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the “dual” assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection. Study Design: Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values for the “dual immunocytochemistry assay” were calculated and compared to histopathological results and to high-risk HPV DNA detection in adult women or teenagers submitted to cervical cancer screening. Results: A total of 151 women were included. The majority (96.2%) of those with negative dual assay results had lower biopsy grades (p < 0.001). Women with cytology results suggestive of cervical cancer had positive dual immunocytochemistry assay results more frequently (p < 0.001), and these positive results were also significantly associated with biopsy findings (p < 0.001) and with high-risk genotype HPV infection (p = 0.007). Specificity and PPV for the dual assay were 0.972 (0.855–0.999) and 0.800 (0.284–0.995), respectively, and 1.000 (0.590–1.000) and 1.000 (0.631–1.000) for HPV detection. Conclusions: The dual immunocytochemistry assay had high specificity and PPV. It reveals a persistent HPV infection, avoiding the need for new tissue collections for biopsies or hybrid capture.

Background: Nearly 500,000 new cases of cervical cancer are estimated annually worldwide. Three vaccines are currently licensed to prevent cervical cancer. The success of vaccination depends mainly on the prevalence of HPV genotypes, and many cases of HPV infection have been diagnosed after vaccination. Our aim was to search for HPV genotyping in cervical samples to verify the proportion of women that remain susceptible to infection even after vaccination. Methods: 21,017 liquid-based cervical (LBC) specimens were received for cytology and HPV detection from 2015 to 2018. Before slide preparations for cytology, a 1,000-μL aliquot was taken from the LBC fixative and subjected to automated DNA extraction and multiplex PCR followed by capillary electrophoresis to detect and classify HPV. Results: HPV was detected in 895 (4.3%) specimens. The most prevalent genotype was HPV-16, followed by HPV-58 and HPV-66. A total of 258 (28.8%) cases were positive for high-risk (HR)-HPV types (66, 59, 39, 56, 30, 35, 53, 51, 68, 82, and 70) that are not covered by the HPV vaccines. Conclusion: A significant proportion of HPV types detected in cytological specimens are representative of HR-HPV not covered by the available vaccines. The health system should be aware of the considerable percentage of women who are not being immunized and will continue to need cervical cancer screening.
