Lintao RCV, Cando LFT, Perias GAS, Tantengco OAG, Tabios IKB, Velayo CL, de Paz-Silava SLM. Current Status of Human Papillomavirus Infection and Cervical Cancer in the Philippines. Front Med (Lausanne) 2022; 9:929062. [PMID: 35795639 PMCID: PMC9251542 DOI: 10.3389/fmed.2022.929062] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 05/30/2022] [Indexed: 11/13/2022] Open
Abstract
Cervical cancer is estimated to cause 341,831 deaths each year, with 9 of 10 deaths occurring in developing countries. Over the past decade, there has been a significant increase in cervical cancer incidence among women in the Philippines. Persistent infection with high-risk human papillomavirus (HPV) is the well-established necessary cause of cervical cancer. Based on limited studies conducted in the Philippines, the prevalence of infection with any HPV genotype was 93.8% for cervical squamous cell carcinoma and 90.9% for cervical adenocarcinomas. HPV types 16 and 18 were the most common HPV genotypes among Filipino patients with cervical cancer. On the other hand, the incidence of HPV infection among Filipino women with normal cervices was 9.2%. The World Health Organization has launched a global agenda of eliminating HPV infection by 2030. One of its key milestones is to vaccinate 90% of girls with the HPV vaccine by 15 years. However, the HPV vaccination rate among Filipino women remains to be unsatisfactory. HPV vaccination has only been included in the Philippine Department of Health's community-based National Immunization Program in 2015. Despite these efforts, the Philippines currently ranks last on HPV program coverage among low-middle income countries, with coverage of only 23% of the target female population for the first dose and 5% for the final dose. The principal reason for the non-acceptance of HPV vaccines was the perceived high cost of vaccination. The low utilization of available cervical cancer screening tests such as Pap smear and visual inspection with acetic acid hampered the Philippines' control and prevention of HPV infection and cervical cancer. Among those diagnosed with cervical cancer in the Philippines, only an estimated 50% to 60% receive some form of treatment. To this end, we summarize the burden of HPV infection and cervical cancer on Filipinos and the risk factors associated with the disease. We present the current screening, diagnostics, treatment, and prevention of HPV-related diseases in the Philippines. Lastly, we also propose solutions on how each building block in health systems can be improved to eliminate HPV infection and reduce the burden of cervical cancer in the Philippines.

Abstract
Immunotherapy has changed the landscape of treatments for advanced disease in multiple neoplasms. More and more patients are long survivors from a metastatic disease. Most recently, the extension of indications and evidence of efficacy in early disease settings, such as the adjuvant and neoadjuvant setting in breast cancer, lung cancer, glioma, and gastric cancer, places more attention on what happens to patients who survive cancer. In particular, we evaluated what happens in young patients, a population in whom some immune-related effects are still poorly described. Immunotherapy is already a reality in early disease settings and the scientific community is lagging in describing what to expect in adolescent and young adult (AYA) patients. For instance, the impact of these therapies on female and male fertility is not clear, similarly to the interaction that may occur between these drugs and pregnancy. This review aims to highlight these little-known topics that are difficult to evaluate in ad hoc studies.

Abstract
OBJECTIVES Natural history of human papillomavirus (HPV) infection in the head and neck region is poorly understood, and their impact on collective HPV-specific immunity is not known. MATERIALS AND METHODS In this study, we have performed a systematic analysis of HPV16-specific cell-mediated immunity (CMI) in 21 women with known oral and genital HPV DNA status and HPV serology (Ab) based on 6-year follow-up data. These women being a subgroup from the Finnish Family HPV Study were recalled for blood sampling to be tested for their CMI-responses to HPV16 E2, E6, and E7 peptides. RESULTS The results showed that HPV16 E2-specific lymphocyte proliferation was more prevalent in women who tested HPV16 DNA negative in oral mucosa and were either HPV16 seropositive or negative than in HPV16 DNA+/Ab+ women (p = 0.046 and p = 0.035). In addition, the HPV16 DNA-/Ab- women most often displayed E6-specific proliferation (p = 0.020). Proportional cytokine profiles indicated that oral HPV16-negative women were characterized by prominent IFN-γ and IL-5 secretion not found in women with persisting oral HPV16 (p = 0.014 and p = 0.040, respectively). CONCLUSIONS Our results indicate that the naturally arising immune response induced by oral HPV infections displays a mixed Th1/Th2/Th17 cytokine profile while women with persisting oral HPV16 might have an impaired HPV16-specific CMI, shifted partly toward a Th2 profile, similarly as seen earlier among patients with high-grade genital HPV lesions. Thus, the lack of HPV 16 E2 and E6 specific T memory cells and Th2 cytokines might also predispose women for persistent oral HPV16 infection which might be related to the risk of cancer.

Abstract
Cancer statistics for adolescents and young adults (AYAs) (aged 15-39 years) are often presented in aggregate, masking important heterogeneity. The authors analyzed population-based cancer incidence and mortality for AYAs in the United States by age group (ages 15-19, 20-29, and 30-39 years), sex, and race/ethnicity. In 2020, there will be approximately 89,500 new cancer cases and 9270 cancer deaths in AYAs. Overall cancer incidence increased in all AYA age groups during the most recent decade (2007-2016), largely driven by thyroid cancer, which rose by approximately 3% annually among those aged 20 to 39 years and 4% among those aged 15 to 19 years. Incidence also increased in most age groups for several cancers linked to obesity, including kidney (3% annually across all age groups), uterine corpus (3% in the group aged 20-39 years), and colorectum (0.9%-1.5% in the group aged 20-39 years). Rates declined dramatically for melanoma in the group aged 15 to 29 years (4%-6% annually) but remained stable among those aged 30 to 39 years. Overall cancer mortality declined during 2008 through 2017 by 1% annually across age and sex groups, except for women aged 30 to 39 years, among whom rates were stable because of a flattening of declines in female breast cancer. Rates increased for cancers of the colorectum and uterine corpus in the group aged 30 to 39 years, mirroring incidence trends. Five-year relative survival in AYAs is similar across age groups for all cancers combined (range, 83%-86%) but varies widely for some cancers, such as acute lymphocytic leukemia (74% in the group aged 15-19 years vs 51% in the group aged 30-39 years) and brain tumors (77% vs 66%), reflecting differences in histologic subtype distribution and treatment. Progress in reducing cancer morbidity and mortality among AYAs could be addressed through more equitable access to health care, increasing clinical trial enrollment, expanding research, and greater alertness among clinicians and patients for early symptoms and signs of cancer. Further progress could be accelerated with increased disaggregation by age in research on surveillance, etiology, basic biology, and survivorship.

Abstract
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.

Abstract
INTRODUCTION Common warts are one of the most prevalent infections affecting the skin. Common warts are caused by human papillomaviruses (HPV), which are ubiquitous in our environment. Most HPV infections are directly controlled and cleared by host immune system, although each case has the potential to persist and transform into a recalcitrant form. It is not exactly clear why certain populations are more susceptible to common warts. AIM To investigate factors affecting the occurence and outcome of common warts. MATERIAL AND METHODS A total of 188 consecutive patients with common warts (106 men, 82 women) and 188 controls were prospectively enrolled. Demographic and clinical characteristics were recorded. The Chi-square, Mann-Whitney U and Kruskal-Wallis tests were used for statistical analysis, with a significance threshold of p<0.05. RESULTS There were not any significant associations between cigarette smoking, alcohol consumption, accompanying diseases, medications, family history of warts and the duration of warts (p=0.102, p=0.317, p=0.535, p=0.535, p=0.535, respectively). There were not any significant associations between cigarette smoking, alcohol consumption, accompanying diseases, medications, family history of warts and the number of warts (p=0.232, p=0.762, p=0.389, p=0.389, p=0.824, respectively). CONCLUSIONS Our study has revealed that smoking is not a risk factor for common warts. However, we suspect the lack of statistical differences are likely due to small sample size of the study. Further studies with larger sample sizes are needed.

Abstract
Introduction Special needs population have barriers accessing healthcare, higher incidence of sexual assaults and lower sexual education. Due to the above this study was conducted- 1) To assess the current prevalence of oral HPV infection among individuals with SHCN (special health care needs) as compared to the general population and 2) To compare the prevalence of HPV vaccination in SHCN individuals (within the recommended age groups) to general population. Methods This data was obtained from NHANES 2013-14 and included 665 individuals with special needs. Weighted prevalence estimates and prevalence ratios (PR) were calculated for oral HPV infection by gender, age (18–59 years), race, smoking history, economic status, and sexual behavior. Prevalence rates were calculated for HPV vaccination. Results Oral HPV was detected in 9% (7.1–11.5; p = 0.05) of special needs adults. High-risk HPV genotypes prevalence was also higher among adults with special needs [5.56% (3.9–7.9) vs 3.87% (2.7–5.4)]. The HPV vaccination rates among 9–26 years special needs females (33.5% vs 37%) and males aged 9–21 years (16.7% vs 21.2%) with special needs was lower than non-special needs individuals. Conclusion There is higher burden of oral HPV infection among adults with special needs compared to general population. Contrastingly, lower vaccination rates were observed among them within the recommended age groups. Further studies are required to determine the barriers to HPV vaccination among individuals with special needs. The prevalence of Oral HPV infection is higher among the adults with special health care needs. Individuals with Special health care needs have lower uptake of HPV vaccination with in the recommended age groups, compared to the general population. Males are more likely to have high-risk Oral HPV infection and lower vaccination rates compared to females.

Abstract
BACKGROUND The association of human papillomavirus (HPV) with head and neck squamous cell carcinoma (HNSCC) was first described in 1982-1983 by the authors of this review. Prompted by this discovery 35 years ago, an entirely new field of HPV research has emerged, resulting in a paradigm shift from smoking and alcohol as the only etiological factors to confirmation of HNSCC as an important group of HPV-related human malignancies. SUMMARY In this review, the authors first describe the scope (i.e., HNSCC) by the anatomic sites of the tumors. Their important site-specific differences in epidemiology are emphasized, and the misconceptions caused by the adopted practice of pooling all tumors from these divergent anatomic sites as a single entity (HNSCC) are pinpointed. The convincing evidence of the established risk factors (smoking and alcohol) is briefly addressed, before entering in the discussion on the causal role of HPV in HNSCC pathogenesis. The global HPV prevalence in different subsets of HNSCC is summarized using the data extracted from all meta-analyses published since 2010. Of all HNSCC subsets, oropharyngeal SCC has an HPV profile distinct form all the other subsets, and the possible mechanisms explaining this intimate association with HPV are discussed. Key Messages: Recent global trends show a constant increase in HNSCC rates particularly among younger age groups. The evidence on cigarette smoking and alcohol consumption as the prime risk factors of HNSCC is overwhelming. During the past 35 years, however, increasing evidence has accumulated implicating an important causal role of HPV in HNSCC. These data have important clinical implications, HPV detection and tailored treatment strategies for HPV-positive HNSCCs currently being an integral part of the oncological management practices of HNSCC.

Abstract
Background The role of passive smoking on cervical carcinogenesis remains controversial. We investigated the association of passive smoking with the risk of cervical intraepithelial neoplasia (CIN) and cervical cancer. Methods The study recruited 1,322 women, aged 18–65 with normal cytology (n = 592), CIN1 (n = 420), CIN2/3 (n = 165), and cervical cancer (n = 145) from 2006 to 2009. This study is a cross-sectional analysis using the baseline data from the Korean human papillomavirus (HPV) cohort study. Detailed information on smoking behaviors and lifestyles were collected using questionnaires. Multinomial logistic regression analysis was performed to estimate multivariable-adjusted odds ratios (ORs). Results Passive smoking was not statistically related to the risk of CINs and cervical cancer. However, passive smoking among non-smokers was associated with higher CIN 1 risk (OR 1.53; 95% confidence interval [CI], 1.07–2.18), compared to not passive smoking, after adjusting for demographic factors, lifestyles, and oncogenic-HPV infection status. CIN 1 risk increased with longer time exposed to passive smoking (P for trend <0.0003). Multivariate odds of <2 hours/day of passive smoking and that of ≥2 hours/day of passive smoking were 2.48 (95% CI, 1.49–4.14) and 2.28 (95% CI, 1.21–4.26) for CIN 1, compared to not passive smoking. Conclusions This study found that passive smoking among non-smoking women is associated with the risk of CIN 1.

Abstract
PURPOSE The aim of the study was to identify risk and protective factors/markers for cervical cancer and cervical intraepithelial neoplasia 3 (CIN3) in Israeli Jewish women in order to settle the discrepancy of low incidence rate of cervical cancer and relatively high incidence rate of CIN3. MATERIALS AND METHODS We conducted two case control studies, which examined the association between potential risk and protective factors/markers for cervical cancer or CIN3 using self administered detailed questionnaires. RESULTS For studying cervical cancer, 40 cases and 40 matched controls were interviewed. In the univariable and multivariable analyses older age, depression or anxiety and ever smoking seemed to act as independent risk factors/markers, while older age at first intercourse was protective. For studying CIN3, 99 cases and 79 controls were interviewed. Multivariable analysis has demonstrated that being born in Israel, depression or anxiety and ever smoking were independent risk factors/markers for CIN3. CONCLUSIONS The risk factors/markers studied, that were associated with cervical cancer or CIN3 among Jewish women in Israel, are similar to those reported in other parts of the world, and do not explain the observed discrepancy of high in-situ cervical cancer rates and low invasive cervical cancer incidence in Israel.

Abstract
Screening for uterine cervical intraepithelial neoplasia (CIN) followed by aggressive treatment has reduced invasive cervical cancer (ICC) incidence and mortality. However, ICC cases and carcinoma in situ (CIS) continue to be diagnosed annually in the United States, with minorities bearing the brunt of this burden. Because ICC peak incidence and mortality are 10-15 years earlier than other solid cancers, the number of potential years of life lost to this cancer is substantial. Screening for early signs of CIN is still the mainstay of many cervical cancer control programs. However, the accuracy of existing screening tests remains suboptimal. Changes in epigenetic patterns that occur as a result of human papillomavirus infection contribute to CIN progression to cancer, and can be harnessed to improve existing screening tests. However, this requires a concerted effort to identify the epigenomic landscape that is reliably altered by HPV infection specific to ICC, distinct from transient changes.

Abstract
Background In order to evaluate the newly implemented gender-neutral HPV vaccination program, knowledge on the pre-vaccine prevalence of HPV infection is of paramount importance. Data on HPV infection among the women with no known previous cytological abnormalities are inexistent in Austria. This study presents data on the prevalence and distribution of HPV genotypes among women with no known cytological abnormalities in west Austria. Methods Women between 18 and 65 years of age attending annual cervical cancer screening examinations were included in the study. Data on socio-demographic and reproductive factors were collected using structured questionnaires. Corresponding cervical swab samples were tested for the presence of HPV DNA and were genotyped. Questionnaire data and HPV status were linked with the corresponding cytological findings. Results A total of 542 women were included in the study. The mean age of the study participants was 35.9 (SD = 11.5). The prevalence of HPV infection was 20.5 %. HPV 16 (6.5 %), HPV 33 (3.3 %) and HPV 31 (3.0 %) were the dominant genotypes detected. Multivariate analysis showed that women younger than 30 years of age, smokers, women with a higher number of lifetime sexual partners and those living in the eastern districts of the study region were at significantly higher risk of HPV infection. Conclusions With this study we present the first data on the prevalence of cervical HPV genotypes among a screening population in Austria. The results not only fill the missing information on HPV infection in this group of women in the country, they also provide baseline data for a future evaluation of the impact of the Austrian gender-neutral HPV immunization program. Moreover, our finding of higher HPV prevalence in the eastern compared to the western district of the study region may – at least partly – explain the east–west gradient in the standardized incidence rate of cervical cancer in the region.

Abstract
BACKGROUND Cervical cancer is one of the most common tumors affecting women with a disproportionate mortality occurring in developing countries. Despite the high prevalence of cervical cancer and cervical neoplasia in Gabon, few studies have been performed to evaluate the prevalence and determinants of HPV infection in this country. The aim of this study was to determine the HPV prevalence and distribution in a population of Gabonese women with normal cytology and cervical abnormalities. METHODS A total of 200 cervical samples collected in the "Departement d'Anatomie et de Cytologie Pathologiques" of the "Faculté de Medecine et des Sciences de la Santé" in Libreville, Gabonwere analyzed. Cytological status was classified according to Bethesda 2001. Nested polymerase chain reaction (PCR) using consensus degenerate PCR primers (MY09/11 and GP5+/6+) was performed for the detection of HPV DNA and HPV typing was done by DNA sequencing. RESULTS Cytological analysis showed that 87 % of women had normal cytology (n = 174/200). Among the 26 women with cytological abnormalities, predominance (61.5 %; 16/26) of low grade squamous intraepithelial lesion (LSIL) was found and no cervical cancer case was detected. Overall, HPV DNA was detected in 60 % of women (120/200). With respect to the cytological status, HPV DNA was found in 57.5 % of women with normal cervix and 76.9 % of women with abnormal cytology. HPV genotyping was performed on 114 HPV positive cases and revealed the presence of 11 distinct genotypes: 16, 18, 33, 31, 56, 6, 66, 70, 35, 45 and 81. The high risk type HPV 16 was the most common genotype found in all cytological categories. Six HPV positive samples could not be typed by DNA sequencing, probably due to multiple HPV infection. Evaluation of possible risk factors showed that HPV infection was related positively with number of sexual partners (≥3, OR = 2.3; 95 % CI, 1.3-4.3), history of sexually transmitted infection (Chlamydia, OR = 1.9; 95 % CI, 1.01-3.4) and marital status (single, OR = 2.0; 95 % CI, 1.1-3.5). CONCLUSION The prevalence of HPV infection among Gabonese women is high. Our findings highlight the need to set up a national program to fight cervical cancer, combining Pap smear test and HPV testing, to improve cervical cancer prevention in Gabon.

Abstract
An anonymous questionnaire survey was conducted among the Hungarian adolescents to establish their use of tobacco, alcohol and drugs in relation to sexual behaviours, knowledge of human papillomavirus (HPV) and cervical cancer, and beliefs and attitudes towards screening and vaccination. Results indicated that adolescent risk-taking health behaviours correlate with risky sexual behaviours. As risk-taking behaviours do not correlate with a better awareness of the risk associated with HPV infection, it is of crucial importance that HPV/cervical cancer preventing educational programmes shall be sensitive to this 'vulnerable' population and draw the attention of these adolescents to their increased risk of sexually transmitted diseases and undesired pregnancies. Well-designed behavioural change interventions may be effective when in addition to providing adolescents (both men and women) with clear information about the implications of an HPV infection, they also aim to improve safer sex behaviours: consistent condom usage, limiting the number of sex partners, as well as encouraging regular participation in gynaecological screenings and uptake of the HPV vaccine. As this study population demonstrated positive attitudes towards the primary and secondary prevention of cervical cancer, the free HPV vaccination for the 12-13-year-old girls in Autumn 2014 will hopefully increase the currently low uptake of the vaccine in Hungary.

Abstract
Background Virus-specific cell-mediated immunity (CMI) plays a role in the outcome of genital HPV infections. To cast further light on the question why most women clear their HPV infection while others develop high-grade cervical intraepithelial neoplasia (CIN), we analyzed HPV16 E2-, E6- and E7 -specific CMI in women who developed CIN during a 10-year follow-up of the Finnish Family HPV cohort. Methods Overlapping 30–35 mer peptides covering the entire HPV16 E2-, E6- and E7 protein sequences were used for defining the lymphocyte proliferation capacity, cytokine production (IL-2, IL-5, IL-10, IL-17A, IFN-γ and TNF-α) and numbers of HPV16 -specific CD4+ CD25+ Foxp3+ regulatory T-cells in 10 women who developed CIN, and in 22 control women who tested constantly HPV-negative during the follow-up. HPV-specific CMI was related to the demographic data including sexual behavior, smoking and alcohol consumption. Results Women with CIN and their controls had similar T-cell mediated immunity against HPV16 E2, E6 and E7 peptide pools. However, nearly fourfold higher T-cell reactivity against common antigens was found in the CIN women than in the healthy donors (p = 0.001). HPV16 E6 stimulation resulted in higher IL-17A secretion in the controls than in the CIN women (p = 0.035). Smoking and use of alcohol affected the T-cell response to common antigens but not to HPV peptides (p = 0.032 and 0.045, respectively). Conclusion While both the CIN women and controls exhibited an HPV16-specific CMI, IL-17A might be of importance in HPV induced pathology. The hyper-responsiveness of the CIN patients to common antigens needs further studies. Smoking and alcohol had no effect on HPV-specific CMI.

Abstract
INTRODUCTION Human papillomavirus (HPV) is one of the most common sexually transmitted infections and is the cause of several different diseases in men and women. Although little is known about HPV infection in men, they are also in the risk group of HPV infection and play an important role in transmitting the virus to women. AIM To define the efficacy of the HPV vaccine through cross-immunization and its role in clearance of HPV infection, and to assess infection-associated factors in men. METHODS This prospective randomized clinical study enrolled 171 evaluable men with genital warts between June 2009 and October 2013. After the initial treatment intervention, 91 patients were randomly assigned to receive HPV vaccine in three doses. Eighty patients were in the control (unvaccinated) group. One hundred-eleven men were single and 60 men were married. Patients who had previous treatment for pre-existing warts and medical disorders that needed chronic treatment or immunosuppression were not included in the randomization. Also 29 men with follow-up less than 12 months and incomplete vaccination were not included. MAIN OUTCOME MEASURES The patients were assessed regarding age, condom use, marital status, number of visible genital warts, and smoking status. Post-treatment follow-up was monthly up to 12th month. RESULTS Mean age was 34 ± 7.6. One hundred fifteen patients were smokers. For the recurrence of warts, age, smoking, vaccination status were insignificant and marital status was significant in the univariable analysis; only marital status preserved significance (HR: 2.0 CI:1.29-3.12 P = 0.002) in the multivariable analysis including vaccination status, marital status, and smoking. CONCLUSION Among the investigated factors vaccination status was not but marital status significantly influenced wart recurrence. Married men had more recurrences in our population. Larger multicenter randomized clinical trials are lacking and seriously required to investigate the therapeutic effect of current quadrivalent HPV vaccine in genital warts.

Abstract
PURPOSE The worldwide prevalence of human papillomavirus (HPV) infection is estimated at 9-13 %. Persistent infection can lead to the development of malignant and nonmalignant diseases. Low-risk HPV types are mostly associated with benign lesions such as anogenital warts. In the present systematic review, we examined the impact of smoking on HPV infection and the development of anogenital warts, respectively. METHODS A systematic literature search was performed using MEDLINE database for peer-reviewed articles published from January 01, 1985 to November 30, 2013. Pooled rates of HPV prevalence were compared using the χ (2) test. RESULTS In both genders, smoking is associated with higher incidence and prevalence rates for HPV infection, whereas the latter responds to a dose-effect relationship. The overall HPV prevalence for smoking patients was 48.2 versus 37. 5 % for nonsmoking patients (p < 0.001) (odds ratio (OR) = 1.5, 95 % confidence interval (CI) 1.4-1.7). Smoking does also increase persistence rates for high-risk HPV infection, while this correlation is debatable for low-risk HPV. The incidence and recurrence rates of anogenital warts are significantly increased in smokers. CONCLUSIONS Most current data demonstrate an association between smoking, increased anogenital HPV infection, and development of anogenital warts. These data add to the long list of reasons for making smoking cessation a keystone of patient health.

Abstract
Background The AS04-adjuvanted bivalent L1 virus-like-particle (VLP) vaccine (Cervarix™) against infection with human papillomavirus (HPV) types 16/18 holds great promise to prevent HPV16/18 infections and associated neoplasias, but it is important to rule out significant co-factors of the neoplasias like smoking. Methods We conducted a pilot study to compare the quantity and quality of HPV16/18 antibody response at baseline and 7 months post vaccination in 104 non-smoking and 112 smoking female participants vaccinated at 0, 1 and 6 months with Cervarix™ (55 and 48 study participants) or with Hepatitis A vaccine (HAVRIX™) (48 and 64 participants, respectively). These 216 women were a sub-sample of 4808 baseline 16- to 17-year old Finnish women initially enrolled in the double-blind, randomized controlled phase III PATRICIA trial. Following end-of-study unblinding in 2009 they were randomly chosen out of all the participants of the three major Finnish PATRICIA study sites in the Helsinki metropolitan area (University of Helsinki, N = 535, and Family Federation Finland, N = 432) and Tampere (University of Tampere, N = 428). Following enrolment, serum samples were collected at month 0 and month 7 post 1st vaccination shot, and were analysed for levels and avidity of IgG antibodies to HPV16 and HPV18 using standard and modified (4 M urea elution) VLP ELISAs. Results We found that at month 7 post vaccination women who smoked (cotinine level > 20 ng/ml) had levels of anti-HPV16/18 antibodies comparable to those of non-smoking women. Low-avidity HPV16/18 IgG antibodies were observed in 16% of the vaccinated women, and active smoking conferred a three-fold increased risk (95% CI 1.0-9.3) of having the low-avidity antibodies. Conclusion Our data suggest that while smoking does not interfere with the quantity of vaccine-induced peak IgG levels, it may affect the avidity of IgG induced by HPV16/18 vaccination.

Abstract
Purpose We investigated the association between alcohol consumption and risk of cervical intraepithelial neoplasia (CIN) and cervical cancer, and determined whether these associations were modified by human papillomavirus (HPV) viral load in high-risk HPV-positive women participating in the Korean HPV cohort study (KHPV). Methods Among the women recruited in the KHPV (n = 1,243) from March 2006 to December 2009, we analyzed normal cytology (n = 581) as control group, CIN1 (n = 299), CIN2/3 (n = 161), or cervical cancer (n = 202). Multinomial logistic analysis was performed to estimate multivariate-adjusted odds ratios (OR). Results Alcohol drinkers had an increased risk of CIN1 (OR = 2.18, 95% CI 1.22–3.89) compared with non-drinkers after adjusting for potential confounders. Subjects with more frequent alcohol consumption had a higher risk of CIN1 (p for linear trend <0.0001). Higher ethanol consumption was associated with an increased risk of CIN1 (p for linear trend = 0.0001). We also observed a synergistic effect between HPV viral load and alcohol consumption: drinkers with a high HPV viral load (≥100 RLU/PC) were associated with a significantly increased risk of CIN1 (OR = 19.1; 95% CI, 6.60–55.3, interaction p<0.001). There were no associations between alcohol drinking and CIN2/3 or cervical cancer. Conclusions HPV viral load and alcohol was associated with the risk of CIN1 among high-risk HPV-positive women. This is the first demonstration that alcohol is an independent and combined risk factor of CIN1.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infectious agent; its 14 oncogenic types are causally associated with 5-10% of all cancers. The major structural HPV protein self-assembles into immunogenic virus-like particles. Two licensed HPV vaccines--the bivalent vaccine comprising HPV types 16 and 18, and the quadrivalent vaccine comprising HPV types 6, 11, 16 and 18--have proven to be safe and efficacious against 6-month-persistent cervical infections of HPV16 and HPV18 and associated precancerous lesions, and both have efficacies of 90-100%. Among baseline HPV-negative adolescent females, vaccine efficacies against the immediate precursor of cervical cancer (intraepithelial neoplasia grade 3) irrespective of HPV type are 93.2% and 43.0% for the bivalent and quadrivalent vaccines, respectively. The quadrivalent vaccine is efficacious (>75% vaccine efficacy) against any of the more-severe precursors of vulval, vaginal and anal cancers. A strong increase in vaccine efficacy with increasing severity of the precancerous lesion is explained by accumulation of the most-oncogenic HPV types 16 and 18 in these lesions. Therefore, prophylactic HPV vaccination will exceed the best results from screening for cancer. With the extremely efficacious prophylactic HPV vaccines, the focus of organized intervention (vaccination and screening) programmes should, however, shift from reducing the HPV disease burden to controlling the prevalence of oncogenic HPV (and nononcogenic HPV) types. Eradication of the major oncogenic HPV types should be pursued.

Abstract
OBJECTIVES The aim of this study was to verify human papillomavirus (HPV) transmission and genotype concordance among heterosexual couples. MATERIALS AND METHODS Thirty-one married couples were evaluated. All male subjects presented with clinically diagnosed HPV-related malignant or potentially malignant lesions and underwent peniscopy and penile swab. Their female counterparts underwent swabs of the uterine cervix and oral mucosa. HPV-DNA detection was performed by polymerase chain reaction and restriction fragment length polymorphism. RESULTS HPV-DNA was detected in the penis, vagina/cervix, and oral cavity of 16 couples (51.61%). Of these, HPV-DNA concordance was observed in 14 couples (87.5%). HPV-DNA was amplified in penile and oral sites of 14 couples. Of these, 13 couples reported fellatio (92.85%), most of them (10 couples, 76.9%) without condom use. HPV-DNA concordance was observed in 7/10 of these couples (70%). The three couples (100%) who reported use of condom during fellatio were HPV-DNA discordant (p = 0.025). CONCLUSIONS Lifetime number of female sexual partners and detection of HPV-DNA in the penile mucosa are surrogate markers of exposure to HPV during marriage. Consistent use of condoms may reduce the risk of HPV transmission. CLINICAL RELEVANCE Oral acquisition of HPV from oro-genital contact is influenced by lack of condom use and previous sexual behavior of the male partner. In addition, oral transmission of the virus due to fellatio is as common as genital transmission.

Abstract
Persistence of human papillomavirus (HPV) infection is necessary for the development of cervical cancer. Additionally, infection with HPV is implicated in the majority of cases of other genital tract malignancies including vulvar, penile, and vaginal cancer. HPV testing and vaccination are a routine part of obstetrical/gynecological clinical practice. With an enhanced public awareness of HPV infections, many patients turn to their obstetricians/gynecologists with questions about transmission, testing, and prevention. In this review, we will discuss the biology of HPV, epidemiology of disease, methods and indications for testing, and vaccination strategies.

Abstract
While the association between smoking and human papillomavirus infection, cervical cancer, and anal cancer has been well studied, evidence on the association between cigarette smoking and anal warts is limited. The purpose of this study was to investigate if cigarette smoking status influences the size of anal warts over time in HIV-infected women in a sample of 976 HIV-infected women from the Women's Interagency HIV Study (WIHS). A linear mixed model was used to determine the effect of smoking on anal wart size. Even though women who were currently smokers had larger anal warts at baseline and slower growth rate of anal wart size after each visit than women who were not current smokers, there was no association between size of anal wart and current smoking status over time. Further studies on the role of smoking and interaction between smoking and other risk factors, however, should be explored.

Abstract
Cervical cancer screening algorithms have changed with the introduction of testing for human papillomavirus (HPV) and better understanding of the natural history of HPV. This review was undertaken to present recent developments related to cervical cancer screening, with HPV testing as a focus. Specifically, guidelines now recommend initiating cervical cancer screening at age 21, stopping at age 65 to 70 if previous tests are normal, and screening no more than every 2 to 3 years. Human papillomavirus testing is now incorporated into guidelines for cervical cancer screening in the United States, with the major impact being the lengthening of recommended screening intervals. Primary screening with HPV testing, although not yet approved in the United States, may serve to increase access to care for the millions of underserved women worldwide who bear most of the burden of cervical cancer. Despite clear guidelines from authoritative sources, many clinicians (including midwives) overscreen women. In cervical cancer screening, as in many areas of women's health care, performing tests that are unlikely to result in useful information may lead to harm.

Abstract
OBJECTIVE We evaluated baseline data from the PApilloma TRIal against Cancer In young Adults (PATRICIA; NCT00122681) on the association between behavioral risk factors and HPV infection and cervical abnormalities. METHODS Women completed behavioral questionnaires at baseline. Prevalence of HPV infection and cervical abnormalities (detected by cytological or histological procedures) and association with behavioral risk factors were analyzed by univariate and stepwise multivariable logistic regressions. RESULTS 16782 women completed questionnaires. Among 16748 women with data for HPV infection, 4059 (24.2%) were infected with any HPV type. Among 16757 women with data for cytological abnormalities, 1626 (9.7%) had a cytological abnormality, of whom 1170 (72.0%) were infected with at least one oncogenic HPV type including HPV-16 (22.7%) and HPV-18 (9.3%). Multivariable analysis (adjusted for age and region, N=14404) showed a significant association between infection with any HPV type and not living with a partner, smoking, age <15 years at first sexual intercourse, higher number of sexual partners during the past 12 months, longer duration of hormonal contraception and history of sexually transmitted infection (STI). For cervical abnormalities, only history of STI (excluding Chlamydia trachomatis) remained significant in the multivariable analysis after adjusting for HPV infection. CONCLUSIONS Women reporting 3+ sexual partners in the past 12 months had the highest risk of HPV infection at baseline. HPV infection was the main risk factor for cervical abnormalities, and history of STIs excluding Chlamydia trachomatis increased risk to a lesser extent. Although behavioral factors can influence risk, all sexually active women are susceptible to HPV infection.

Abstract
BACKGROUND The influence of smoking on the natural history of HPV infection in men is not well understood. Smoking could influence the incidence and persistence of HPV infections by suppressing local immune function, increased cellular proliferation, upregulated proinflammatory factors, or induced host DNA damage resulting in increased susceptibility to infection. The purpose of this analysis is to assess prevalent HPV infections by smoking status in men, and to determine baseline risk of HPV infection associated with smoking. METHODS The HPV in Men (HIM) study is a multinational prospective study of the natural history of HPV infections in men. Samples from the coronal sulcus, glans penis, shaft, and scrotum were combined for HPV DNA testing. Multivariable logistic regression was used to assess the association between smoking and any-, oncogenic-, and nononcogenic HPV infections. RESULTS Our analyses revealed that current smoking was associated with an increased risk of any HPV infection (OR = 1.19; 95% CI: 1.01-1.41) and oncogenic HPV infection (OR = 1.24; 95% CI: 1.05-1.47). However, the association between smoking and any HPV infection (OR = 1.35; 95% CI: 1.05-1.73) and oncogenic HPV infection (OR = 1.46; 95% CI: 1.11-1.92) was only evident among men reporting fewer lifetime sexual partners. DISCUSSION These results suggest that current smokers with the fewest number of sexual partners are associated with an increased risk for oncogenic HPV infection. IMPACT The relationship between smoking and HPV infection remains understudied in men; these data shed new light on the interplay between smoking, sexual activity, and risk of HPV infection.

Abstract
In addition to oncogenic 'high-risk' human papillomaviruses (HR-HPV), several co-factors are needed in cervical carcinogenesis, but it is poorly understood whether these HPV co-factors associated with incident cervical intraepithelial neoplasia (CIN) grade 1 are different from those required for progression to CIN2 and CIN3. To gain further insights into the true biological differences between CIN1, CIN2 and CIN3, we assessed HPV co-factors increasing the risk of incident CIN1, CIN2 and CIN3. Data from the New Independent States of the Former Soviet Union (NIS) Cohort (n = 3187) and the Latin American Screening (LAMS) Study (n = 12,114) were combined, and co-factors associated with progression to CIN1, CIN2 and CIN3 were analysed using multinomial logistic regression models with all covariates recorded at baseline. HR-HPV-positive women (n = 1105) represented a subcohort of all 1865 women prospectively followed up in both studies. Altogether, 90 (4.8%), 39 (2.1%) and 14 (1.4%) cases progressed to CIN1, CIN2 and CIN3, respectively. Baseline HR-HPV was the single most powerful predictor of incident CIN1, CIN2 and CIN3. When controlled for residual HPV confounding by analysing HR-HPV-positive women only, the risk profiles of incident CIN1, CIN2 and CIN3 were unique. Completely different HPV co-factors were associated with progression to CIN1, CIN2 and CIN3 in univariate and multivariate analyses, irrespective of whether non-progression, CIN1 or CIN2 was used as the reference outcome. HPV co-factors associated with progression to CIN1, CIN2 and CIN3 display unique profiles, implicating genuine biological differences between the three CIN grades, which prompts us to re-visit the concept of combining CIN2 with CIN3 or CIN1.

Abstract
Cervical cancer (CC) is the third most common cancer in women worldwide; however, CC is a preventable disease, and much effort should be done to prevent it. Persistence of high-risk HPV infection is the strongest epidemiologic risk factor for CC, however it is not sufficient for development of the disease it cofactors should be present. In 2004; IARC listed cervical cancer among those causally related to smoking. Smoking interferes with incidence and prevalence of HPV infection and is associated with cervical intraepithelial neoplasia and invasive CC. Multiple factors seem to intervene on cervical carcinogenesis related with tobacco, especially by direct local carcinogenic effect and local immunosuppression. Smoking addition is also closely related with other confounding factors, like unfavorable psychosocial events, systemic immunity, contraception, and nutrition, which got difficult epidemiologic evaluation of smoking role on cervical carcinogenesis. Smoking habits should be taken in account in clinical practice and in research concerning CC.

Abstract
OBJECTIVE To study the incidence times and rates for cervical intraepithelial neoplasia (CIN) and its predictors. MATERIAL AND METHODS This is a prospective follow-up study at Turku University Hospital, Finland. The Finnish Family human papillomavirus (HPV) study comprised 329 pregnant women followed up for 3 years. In an extension of the follow-up period, 171 women participated in an additional 3 years follow-up. Cervical scrapings for HPV testing and cervical smears were collected at each follow-up visit (2, 12, 24 and 36 months and 6 years). Following two abnormal cervical smears, colposcopy with biopsies was done. The main outcome measures were actuarial and crude incidence times, incidence rates and predictors of incident CIN. RESULTS During the follow-up period, 10 women (3.2%) developed biopsy-confirmed CIN, and four presented with incident atypical squamous cells suggesting high-grade squamous intraepithelial lesion cytology. The CIN/squamous intraepithelial lesion developed in 74.5 and 66.3 months, with crude incidence rates of 13.4/1,000 and 15.1/1,000 women months at risk, respectively. In multivariate Poisson regression, independent predictors of incident CIN were as follows: high-risk HPV positive at baseline (incidence rate ratio = 5.54; 95% confidence interval 1.02-30.14, p= 0.048); type-specific high-risk HPV persistence during follow-up (incidence rate ratio = 5.84; 95% confidence interval 2.28-17.93, p= 0.0001); cervical smear cytologically diagnosed for atypical squamous cells of undetermined significance or worse at any follow-up visit (incidence rate ratio = 4.56; 95% confidence interval 2.37-8.78, p= 0.0001); and new sexual partner during follow-up (incidence rate ratio = 9.45; 95% confidence interval 1.90-46.97, p= 0.006). CONCLUSION The results indicate that combined use of cervical smear and HPV testing, with prompt referral to colposcopy, enables accurate detection of incident CIN well before progression to invasive cancer. In addition to baseline and persistent high-risk HPV, abnormal cervical smear and new sexual partner are key predictors of incident CIN.

Abstract
Persistent infection with high-risk human papillomaviruses (HR-HPVs) is involved in cervical cancer (CC), a major cause of cancer mortality worldwide. Infection occurs primarily at the transformation zone (TZ), the most estrogen- and retinoid-sensitive region of the cervix. Development of CC affects a small percentage of HR-HPV-infected women and often takes decades after infection, suggesting that HR-HPV is a necessary but not sufficient cause of CC. Thus, other cofactors are necessary for progression from cervical HR-HPV infection to cancer such as long-term use of hormonal contraceptives, multiparity, smoking, as well as micronutrient depletion and in particular retinoid deficiency, which alters epithelial differentiation, cellular growth and apoptosis of malignant cells. Therefore, early detection of HR-HPV and management of precancerous lesions together with a profound understanding of additional risk factors could be a strategy to avoid this disease. In this review we focus on the synergic effect of estrogens, retinoid deficiency and HR-HPVs in the development of CC. These risk factors may act in concert to induce neoplastic transformation in squamous epithelium of the cervix, setting the stage for secondary genetic or epigenetic events leading to cervical cancer.

Abstract
BACKGROUND Although cigarette smoking has been associated with increased human papilloma virus (HPV) detection, its impact on HPV DNA load is unknown. METHODS The study subjects were women who were positive for HPV16 and/or HPV18 at enrollment into the Atypical Squamous Cells of Undetermined Significance-Low-grade Squamous Intraepithelial Lesion Triage Study. Assessments of exposure to smoke and sexual behavior were based on self-report. Viral genome copies per nanogram of cellular DNA were measured by multiplex real-time PCR. Linear or logistic regression models were used to assess the relationship between cigarette smoking and baseline viral load. RESULTS Of the 1,050 women (752 with HPV16, 258 with HPV18, and 40 with both HPV16 and HPV18), 452 (43.0%) were current smokers and 101 (9.6%) were former smokers at enrollment. The baseline viral load was statistically significantly greater for current compared with never smokers (P = 0.03 for HPV16; P = 0.02 for HPV18) but not for former smokers. Among current smokers, neither HPV16 nor HPV18 DNA load seemed to vary appreciably by age at smoking initiation, smoking intensity, or smoking duration. The results remained similar when the analysis of smoking-related HPV16 DNA load was restricted to women without detectable cervical abnormality. CONCLUSION Higher baseline HPV16 and HPV18 DNA load was associated with status as a current but not former smoker. A lack of dose-response relationship between cigarette smoking and viral load may indicate a low threshold for the effect of smoking on HPV DNA load.

Abstract
Repeated measurements of smoking, cervical human papillomavirus (HPV) status and sexual behaviour were used to measure the risk of high-grade cervical intraepithelial neoplasia (CIN) in relation to changes in smoking and cervical HPV status, and to explore the impact of smoking on the acquisition and duration of incident cervical HPV infection. Included in this longitudinal analysis are 1485 women aged 15–19 years: 1075 were HPV-negative and cytologically normal at recruitment; 410 were HPV-positive, cytologically abnormal or both, at this time. Women re-attended every 6 months, when samples were taken for cytological and virological examination. Current smoking intensity was associated with an increased risk of high-grade CIN, after controlling for cervical HPV status (compared to non-smokers, hazards ratio (HR) for 10 or more cigarettes per day = 2.21, 95% confidence interval (CI) 1.19–4.12, p-trend = 0.008). In women who were HPV-negative and cytologically normal at recruitment, current smoking was not significantly associated with the risk of acquiring a cervical HPV infection, after controlling for life-time number of partners and age of oldest partner (HR = 1.13, 95% CI 0.90–1.41); nor did it prolong the length of time during which HPV could be detected (HR = 1.03, 95% CI 0.78–1.34). Current smoking intensity is an independent risk factor for high-grade CIN in young women, after controlling for cervical HPV infection.

Abstract
BACKGROUND The purpose of this study was to assess the effect of smoking on the prevalence and incidence of high-risk human papillomavirus (hr-HPV) infection and cervical intraepithelial neoplasia (CIN) in a large sample of Latin American women. METHODS The study examines baseline data on over 12,000 women included in the Latin American Screening Study (Brazil and Argentina), and over 1000 women followed-up for a period of 36 months. Three groups were formed: never smokers, current, and past smokers. The prevalence of hr-HPV infection and CIN were compared between the study groups. In the prospective analysis, women were controlled at 6-month intervals to assess the cumulative risk of incident hr-HPV infection, smear abnormalities, and CIN. RESULTS A higher prevalence (21.7%) of hr-HPV infection was found among current smokers as compared to never smokers (16.5%) or past smokers (13.5%). Being current smoker was significantly (P <0.01) associated with hr-HPV detection (OR = 1.6; 95% CI = 1.2-2.1). Being a current smoker was a significant predictor of incident hr-HPV during the follow-up [Hazards ratio (HR) = 1.4; 95% CI 1.0-1.9]. For incident CIN2+, being a past smoker (HR = 3.6; 95% CI 1.6-9.8) or current smoker (HR = 3.6; 95% CI 1.5-8.6) were the significant independent predictors. Current and past smokers had a significantly increased risk of incident CIN2+ (P <0.01). CONCLUSIONS Smoking increases the risk of contracting hr-HPV infection and modifies the effect of a persistent hr-HPV infection by further increasing the risk of developing CIN2+. It seems that this effect modification persists over several years after smoking cessation.

Abstract
Research has suggested a link between smoking and cervical cancer; however, little data are available on secondhand smoke (SHS) exposure and cervical cancer risk. This article reviews the literature on the links among smoking, SHS exposure and cervical cancer. The review was based on a search of electronic databases. The research reviewed clearly showed that smoking increases cervical cancer risk through myriad mechanisms that interact with genetics and the pathologic processes leading to cervical cancer. However, less is understood about the role of SHS in cervical cancer. With new technology enabling scientists to examine how genomic structure responds to environmental stimuli, more information should be forthcoming on links between SHS exposure, biomarkers, and genetic changes involved in the development of cervical cancer.

Abstract
Repeat episodes of HPV-related external genital warts reflect recurring or new infections. No study before has been sufficiently powered to delineate how tobacco use, prior history of EGWs and HIV infection affect the risk for new EGWs. Behavioral, laboratory and examination data for 2,835 Multicenter AIDS Cohort Study participants examined at 21,519 semi-annual visits were evaluated. Fourteen percent (391/2835) of men reported or were diagnosed with EGWs at 3% (675/21,519) of study visits. Multivariate analyses showed smoking, prior episodes of EGWs, HIV infection and CD4+ T-lymphocyte count among the infected, each differentially influenced the risk for new EGWs.

The natural history of oncogenic human papillomavirus (HPV) infections results from interactions of the virus, the host, and multiple cofactors. We studied the association between humoral immune response to HPV and smoking in 191 HPV infected women prospectively. Two follow-up samples (first and last) were analysed for serum cotinine levels, IgA and IgG antibodies to HPV16 and 18, and Chlamydia trachomatis using ELISA methods. HPV DNA analyses were also performed, and HPV16/18 antibodies were detectable in 23 of 40 (57.5%) HPV DNA-positive women. We performed age-stratified analyses and found that young smokers were less likely to develop HPV16/18 antibodies than non-smokers (OR: 0.2, 95% CI 0.0-0.9). Furthermore, they had a significantly decreased tendency of maintaining constant HPV16/18 IgG antibody positivity by the end of the follow-up (OR: 0.1, 95% CI 0.0-0.8). Smoking did not affect the development of HPV antibody responses in women over 30 y of age. Our results suggest that smoking may induce impaired antibody response in HPV16/18-infected young women.

Abstract
Our objective was to compare the association between tobacco smoking and chewing and the risk of multiple human papillomavirus (HPV) infections and cervical squamous intraepithelial lesions (SILs) in two populations with different tobacco exposure. We studied 2,162 women from Côte d'Ivoire, West Africa, and 419 women from Finland, Northern Europe, with baseline data on cervical screening, HPV DNA status and smoking and chewing habits. The proportion of women who smoked and/or chewed tobacco was higher in Finland (36.8%) than in Côte d'Ivoire (3.7%), where tobacco chewing (2.6%) was more common than tobacco smoking (1.4%). Having multiple HPV infections was common in HPV16 and/or 18-infected women (60.4% in Finland and 47.2% in Côte d'Ivoire). There was no increased risk of multiple HPV infections among tobacco consumers. We found that women >or=30 years of age exposed to tobacco through smoking in Finland (OR: 2.2, 95% CI: 0.5-8.7) and chewing in Côte d'Ivoire (OR: 5.5, 95% CI: 2.1-14) had a moderately or highly increased risk of high-grade SIL, respectively. In the latter, the risk was statistically significant. Our findings emphasize the need for health initiatives targeted to prevent tobacco smoking or chewing among women especially in less industrialized countries.
