Abstract
The incorporation of HPV DNA testing into cervical screening programs has shown that many HPV-positive women are cytologically normal, with HPV-positivity fluctuating throughout life. Such results suggest that papillomaviruses may persist in a latent state after disease clearance, with sporadic recurrence. It appears that virus latency represents a narrow slot in a wider spectrum of subclinical and possibly productive infections. Clinical studies, and animal model infection studies, suggested a key role for host immune surveillance in maintaining such asymptomatic infections, and although infections may also be cleared, most studies have used the term 'clearance' to describe a situation where the presence of HPV DNA falls below the clinical detection level. Given our knowledge of papillomavirus immune evasion strategies and the restricted pattern of viral gene expression required for 'basal cell' persistence, the term 'apparent clearance' and 'subclinical persistence' of infection may better summarise our understanding. Subclinical infection also encompasses the lag phase, which occurs between infection and lesion development. This is dependent on infection titre, with multifocal infections developing more rapidly to disease. These concepts can usefully influence patient management where HPV-positivity occurs sometime after the onset of sexual activity, and where vertical transmission is suspected despite a lag period.

Abstract
Penile intraepithelial neoplasia (PeIN) is currently classified in human papillomavirus (HPV)- and non-HPV-related subtypes with variable HPV genotypes. PeINs are frequently associated with other intraepithelial lesions in the same specimen. The aim of this study was to detect and compare HPV genotypes in PeINs and associated lesions using high-precision laser capture microdissection-polymerase chain reaction and p16INK4a immunostaining. We evaluated resected penile specimens from 8 patients and identified 33 PeINs and 54 associated lesions. The most common subtype was warty PeIN, followed by warty-basaloid and basaloid PeIN. Associated lesions were classical condylomas (17 cases), atypical classical condylomas (2 cases), flat condylomas (9 cases), atypical flat condylomas (6 cases), flat lesions with mild atypia (12 cases), and squamous hyperplasia (8 cases). After a comparison, identical HPV genotypes were found in PeIN and associated lesions in the majority of the patients (7 of 8 patients). HPV16 was the most common genotype present in both PeIN and corresponding associated lesion (50% of the patients). Nonspecific flat lesions with mild atypia, classical condylomas, and atypical condylomas were the type of associated lesions most commonly related to HPV16. Other high-risk HPV genotypes present in PeIN and associated nonspecific flat lesion with mild atypia were HPV35 and HPV39. In this study of HPV in the microenvironment of penile precancerous lesions, we identified identical high-risk HPV genotypes in PeIN and classical, flat, or atypical condylomas and, specially, in nonspecific flat lesions with mild atypia. It is possible that some of these lesions represent hitherto unrecognized precancerous lesions.

Abstract
Background Flat penile lesions (FPL) in heterosexual men are thought to play a role in the transmission of HPV. We investigated the association between FPL and penile HPV, and explored determinants of FPL in men who have sex with men (MSM). Methods In 2015–2016, MSM were recruited based on HIV and penile HPV status in a previous cohort. MSM self-completed a questionnaire. Peniscopy was performed after application of acetic acid to visualize FPL. Penile physician-collected samples were tested for HPV-DNA using the highly sensitive SPF10-PCR DEIA/LiPA25 system. HPV viral load (VL) was determined using a quantitative type-specific (q)PCR targeting the L1-region. Presence of HPV and HIV, HPV VL and circumcision status were compared between MSM with and without FPL. Results We included 116 MSM, of whom 59/116 (51%) MSM were HIV-positive and 54/116 (47%) had FPL. A penile HPV infection was present in 31/54 (57%) MSM with FPL and 34/62 (55%) MSM without FPL (p = 0.8). There was no difference between MSM with and without FPL regarding presence of penile HPV infection, HPV VL, HIV status or circumcision status (p > 0.05 for all). Conclusion Among MSM in Amsterdam, we found no association between FPL and penile HPV, HPV VL, HIV status or circumcision status.

Abstract
BACKGROUND Human papillomavirus (HPV) epidemiological research has generally been individual based, typically focusing on women, with couple-based research mostly consisting of cross-sectional assessment of prevalent HPV infection in both partners. OBJECTIVE The HPV Infection and Transmission among Couples through Heterosexual activity (HITCH) study was set up to investigate the transmissibility of HPV among young, recently formed couples in Montreal, Canada. This paper provides an overview of the HITCH cohort study design and procedures as well as a narrative summary of the most important findings. METHODS HITCH is a longitudinal investigation of HPV transmission in recently formed heterosexual partnerships initiated within 6-month pre-enrollment, a time at which considerable transmission is believed to occur. A total of 549 newly formed dyads were recruited (2005-2011) from postsecondary institutions, including 502 young women and their male partners. An additional 46 males were enrolled at follow-up, as some women enrolled a subsequent partner at follow-up. Women aged 18-24 years were followed for 24 months for acquisition of HPV types not present at enrollment, whereas men returned for a single follow-up visit at month 4, for a sum total of 3361 clinic visits. The last follow-up visit occurred in January 2014. Extensive sociodemographic, sexual behavioral, and medical history data were collected every 2-4 months using computer-assisted, self-administered questionnaires. Furthermore, participants provided genital, blood, oral, and hand specimens for HPV assessment. RESULTS Although in its early analysis stage, HITCH has produced important publications. Findings from HITCH have increased the available knowledge about the natural history of HPV transmission and its determinants, provided further evidence regarding oral-oral and oral-genital routes of HPV transmission, and supplied empirically valid epidemiological parameters of HPV transmission to assist mathematical modelers in health economic assessments. In addition, HITCH data were made available to several multistudy collaborations evaluating new HPV detection assays and evidence for-or-against HPV type replacement following the introduction of HPV vaccination. CONCLUSIONS HITCH will continue to offer a unique resource for research on HPV transmission. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID) RR1-10.2196/11284.

Abstract
Laser capture microdissection-polymerase chain reaction (LCM-PCR) supported by p16 was used for the first time to demonstrate human papillomavirus (HPV) DNA in histologically specific penile lesions, which were as follows: squamous hyperplasia (12 lesions, 10 patients), flat lesions (12 lesions, 5 patients), condylomas (26 lesions, 7 patients), penile intraepithelial neoplasia (PeIN) (115 lesions, 43 patients), and invasive squamous cell carcinomas (26 lesions, 26 patients). HPV was detected by whole-tissue section and LCM-PCR. LCM proved to be more precise than whole-tissue section in assigning individual genotypes to specific lesions. HPV was negative or very infrequent in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of carcinomas. HPV was strongly associated with condylomas, warty/basaloid PeIN, adjacent flat lesions, and warty/basaloid carcinomas. A single HPV genotype was found in each lesion. Some condylomas and flat lesions, especially those with atypia, were preferentially associated with high-risk HPV. Unlike invasive carcinoma, in which few genotypes of HPV were involved, there were 18 HPV genotypes in PeIN, usually HPV 16 in basaloid PeIN but marked HPV heterogeneity in warty PeIN (11 different genotypes). Variable and multiple HPV genotypes were found in multicentric PeIN, whereas unicentric PeIN was usually related to a single genotype. There was a correspondence among HPV genotypes in invasive and associated PeIN. p16 was positive in the majority of HPV-positive lesions except condylomas containing LR-HPV. p16 was usually negative in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of squamous cell carcinomas. In summary, we demonstrated that LCM-PCR was a superior research technique for investigating HPV genotypes in intraepithelial lesions. A significant finding was the heterogeneity of HPV genotypes in PeIN and the differential association of HPV genotypes with subtypes of PeIN. The presence of atypia and high-risk HPV in condylomas and adjacent flat lesions suggests a precursor role, and the correspondence of HPV genotypes in invasive carcinomas and associated PeIN indicates a causal relation. Data presented support the bimodal hypothesis of penile cancer carcinogenesis in HPV-driven and non-HPV-driven carcinomas and justify the current WHO pathologic classification of PeIN in special subtypes.

Abstract
Cervical cancer is a major source of illness and death among women worldwide and genital infection with oncogenic human papillomavirus (HPV) its principal cause. There is evidence of the influence of the male factor in the development of cervical neoplasia. Nevertheless, the pathogenic processes of HPV in men are still poorly understood. It has been observed that different HPV types can be found among couples. The objective of the present study was to investigate HPV infections in female patients (n = 60 females/group) as well as in their sexual partners and to identify the concordance of HPV genotypes among them. By using the polymerase chain reaction, we detected a 95% prevalence of HPV DNA in women with cervical intraepithelial neoplasia (CIN) compared to 18.3% in women with normal cervical epithelium, with a statistically significant difference (P < 0.001). The HPV DNA prevalence was 50% in male partners of women with CIN and 16.6% in partners of healthy women. In the control group (healthy women), only 9 couples were simultaneously infected with HPV, and only 22.2% of them had the same virus type, showing a weak agreement rate (kappa index = 0.2). Finally, we observed that HPV DNA was present in both partners in 30 couples if the women had CIN, and among them, 53.3% shared the same HPV type, showing moderate agreement, with a kappa index of 0.5. This finding supports the idea of circulation and recirculation of HPV among couples, perpetuating HPV in the sexually active population, rather than true recurrences of latent infections.

Abstract
This chapter addresses the natural history of anogenital human papillomavirus (HPV) infection. Cervical infections are the best understood HPV infection. Cervical HPV persistence is the known necessary event for the development of cervical cancer. New infections appearing at any age are benign unless they persist. Several long-term natural history studies have now shed light on the very low risk of cervical intraepithelial neoplasia (CIN) 3+ in women past the peak of HPV acquisition (e.g., 30 or older) who are HPV-negative or clear their HPV. Although data on transmission of HPV are finally emerging, rates of transmission between heterosexual couples vary widely among studies. Factors that affect the calculations of these rates include a) intervals between testing points, b) rates of concordance or discordance at baseline, and c) difficulty in defining established infections versus contamination. Both cervix to anus and anus to cervix autoinoculation in the same woman appears to be quite common. Whether either site serves as a long-term reservoir is unknown. Studies show that anal infections in women and in men who have sex with men are quite common with cumulative rates up to 70-90%. Similarly, clearance of anal HPV is also common, with few individuals showing persistence unless they are human immunodeficiency virus (HIV)-infected. HIV strongly influences the development of anal intraepithelial neoplasia (AIN). The few studies on the natural history of AIN in HIV-infected men suggest that high-grade AIN is a precursor to invasive anal cancer. Although no natural history studies of AIN are available in women, women with other HPV-associated lesions, including CIN3+ and vulvar cancer, have higher rates of anal cancer. Data on the natural history of HPV of the male genitalia are also emerging, although penile intraepithelial neoplasia is poorly understood. Cumulative rates of HPV are extremely high in men and risks are associated with sexual behavior. Unlike women, prevalence rates are steady across all ages, suggesting that men do not develop protection against reinfection. This article forms part of a special supplement entitled "Comprehensive Control of HPV Infections and Related Diseases" Vaccine Volume 30, Supplement 5, 2012.

Abstract
OBJECTIVE To gain a better understanding of human papillomavirus (HPV) transmission dynamics between sexual partners, HPV-type-specific concordance was investigated. METHODS Twenty-nine couples were enrolled in this cross-sectional study. Mean age was 30.5 years (range = 19.1-42.6 y) for men and 28.2 years (range = 19.4-44.5 y) for women. Samples were collected at the glans penis, penile shaft, and scrotum in men and at the endo/ectocervix and labia/vulva, and perineum in women. Samples were analyzed for the presence of HPV DNA first by polymerase chain reaction and then genotyped using the reverse-line blot method. RESULTS Human papillomavirus prevalence for any HPV type was 75.9% among men and 86.2% among women. Eleven men and 10 women were infected with multiple HPV types. At least partial type-specific concordance was observed in 66% of the couples. Forty-one percent of the couples had perfect concordance. In 11 couples (37.9%), complete discordance was observed. CONCLUSIONS These results provide valuable information about HPV-type-specific concordance and demonstrate the complexity of transmission dynamics in heterosexual couples.

Abstract
Human papillomavirus (HPV)-associated penile lesions in men may increase the risk of HPV transmission to their female partners. Risk factor data on HPV-associated penile lesions are needed from regions with a high burden of cervical cancer. Visual inspection of the penis was conducted using a colposcope at the 24-month visit among participants in a randomized controlled trial of male circumcision in Kenya, from May 2006 to October 2007. All photos were read independently by two observers for quality control. Penile exfoliated cells sampled from the glans/coronal sulcus and the shaft were tested for HPV DNA using GP5+/6+ PCR and for HPV16, 18 and 31 viral loads using a real time PCR assay. Of 275 men, 151 were circumcised and 124 uncircumcised. The median age was 22 years. Circumcised men had a lower prevalence of flat penile lesions (0.7%) versus uncircumcised (26.0%); adjusted odds ratio (OR) = 0.02; 95% confidence interval (CI) = 0.003-0.1. Compared to men who were HPV negative, men who were HPV DNA positive (OR = 6.5; 95% CI = 2.4-17.5) or who had high HPV16/18/31 viral load (OR = 5.2; 95% CI = 1.1-24.4) had higher odds of flat penile lesions. Among men with flat penile lesions, HPV56 (29.0%) and 16 (25.8%) were the most common types within single or multiple infections. Flat penile lesions are much more frequent in uncircumcised men and associated with higher prevalence of HPV and higher viral loads. This study suggests that circumcision reduces the prevalence of HPV-associated flat lesions and may ultimately reduce male-to-female HPV transmission.

Abstract
Penile squamous cell carcinoma (SCC) is uncommon in Europe, where it accounts for approximately 0.7% of all malignant tumors in men. The main risk factors are poor hygiene, lack of circumcision, human papillomavirus (HPV) infection, and certain chronic inflammatory skin diseases. HPV infection is detected in 70% to 100% of all penile in situ SCCs and in 30% to 50% of invasive forms of the disease, mainly basaloid and warty SCCs. In situ tumors can be treated conservatively, but close monitoring is essential as they become invasive in between 1% and 30% of cases. The treatment of choice for penile SCC is surgery. Inguinal lymph node irradiation is no longer recommended as a prophylactic measure, and it appears that selective lymph node biopsy might be useful for reducing the morbidity associated with prophylactic inguinal lymph node dissection. Survival is directly related to lymph node involvement. Improving our knowledge of underlying molecular changes and their associated genotypes will open up new therapeutic pathways.

Abstract
We estimated human papillomavirus (HPV) transmission rates among persons with documented sexual exposure to an infected partner. Recently formed couples enrolled in the HITCH Study (HPV Infection and Transmission among Couples through Heterosexual activity) in Montreal, Canada, and provided genital specimens for DNA testing of 36 HPV genotypes. At enrollment, 179 couples were discordant for ≥1 HPV types; transmission was observed at follow-up in 73 partnerships. There was little difference between the male-to-female (3.5 per 100 person-months, 95% confidence interval [CI], 2.7-4.5) and female-to-male (4.0 per 100 person-months, 95% CI, 3.0-5.5) transmission rates. Rates did not vary with the lifetime number of partners reported by the initially uninfected partner, providing no evidence of reduced susceptibility for those with extensive sexual histories. Transmission was also relatively homogeneous across HPV genotypes and alpha species and oncogenic risk categories. The findings contribute to a small but growing evidence base regarding the natural history of HPV transmission.

Abstract
HPV surveillance is necessary to monitor the impact and success of HPV immunization programs. This study was designed to evaluate the performance of HPV testing in urine to assess its suitability for epidemiological and surveillance purposes. A total of 90 females and 117 males were recruited from a UK drop-in clinic offering integrated sexual health services. A urine sample and comparator gold-standard sample (cervical liquid-based cytology sample or penile swab) was collected from each subject. HPV detection was performed using a PCR-based assay. Discrepancy between the two overall distributions [urine vs. gold standard (GS)] was measured. At the individual level, sensitivity and specificity of HPV detection in urine versus GS was measured. Prevalence of HPV was higher in urine compared to GS in both females and males. At the individual level, sensitivity of urine versus GS for HPV detection was 90.5% (79.3-96.9) and 55.9% (37.8-72.8) in females and males, respectively. The overall distribution of HPV types in urine was similar to that in gold standard, (P = 0.78; male, P = 0.88; female). Type-specific matches in urine versus GS were achieved in 71% (61-79.5) and 63.2% (54.2-71.4) of samples from females and males, respectively. Urine, particularly from females, is a useful biospecimen for HPV surveillance purposes. Further examination into the usefulness of urine from males, including choice of relevant gold-standard comparator, is required.

Soskin A, Vieillefond A, Carlotti A, Plantier F, Chaux A, Ayala G, Velazquez EF, Cubilla AL. Warty/basaloid penile intraepithelial neoplasia is more prevalent than differentiated penile intraepithelial neoplasia in nonendemic regions for penile cancer when compared with endemic areas: a comparative study between pathologic series from Paris and Paraguay. Hum Pathol 2011; 43:190-6. [PMID: 21835427 DOI: 10.1016/j.humpath.2011.04.014] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2011] [Revised: 04/19/2011] [Accepted: 04/22/2011] [Indexed: 11/30/2022]
Abstract
Penile squamous cell carcinoma shows an ample geographic variation in its prevalence with regions of low (North America, Europe, Japan, and Israel) and high (Africa, Asia, and South America) incidence. However, the geographic variation in the distribution of penile intraepithelial neoplasia is not well established. The aim of the present study was to compare the distribution of in situ and invasive lesions between geographic areas with low (France) and high (Paraguay) penile cancer incidence using a series of consecutive cases. The French series included 86 cases (57 in situ and 29 in situ + invasive squamous cell carcinoma), and the Paraguayan series, 117 cases (31 in situ and 86 in situ + invasive squamous cell carcinoma). Incidence of invasive squamous cell carcinoma in the overall samples was higher in the Paraguayan series (P < .00001). Comparing the Paraguayan and the French series, differentiated penile intraepithelial neoplasia was more prevalent in the former (65.0% versus 19.8%), whereas lesions showing warty and/or basaloid features predominated in the latter (35.0% versus 80.2%) to a significant level (P < .00001). This distinctive pattern of differential distribution was maintained when cases with associated invasive squamous cell carcinoma were excluded. The pattern of distribution of lichen sclerosus was also distinctive, with a significantly higher prevalence in the Paraguayan population when compared with the French series (32.5% versus 12.8%, P = .0015). In summary, there appears to be a distinctive distribution of penile precursor lesions depending on the geographic region in consideration. Penile intraepithelial neoplasia with warty and/or basaloid features predominated in low-incidence areas, whereas differentiated penile intraepithelial neoplasia was more prevalent in endemic regions for penile cancer. Further prospective studies in matched populations and from different geographic regions are needed to further clarify the reasons for this discrepancy.

Abstract
Few data exist regarding the human papillomavirus (HPV) types in penile warts (PW) of HIV-infected men in Africa. Nurses collected penile swabs for HPV typing from 74 HIV-positive men with PW. HPV genotyping was performed using the Roche Linear Array Test. Analysis was performed on data relating to 74 samples. The mean age of the men was 36.0 years and 78.5% (51/65) were uncircumcised. Of the 73/74 validated results, all tested positive for HPV; 42.5% (31/73) and 32.9% (24/73) had HPV types 6 and 11, respectively. 84.9% of men tested positive for any oncogenic type: 20/73 (27.4%) were positive for type 16, 11/73 (15.1%) were positive for type 18 and 8/73 (11.0%) men had both types. Our study shows a high prevalence (68.5%) of HPV type 6 and/or 11 in this male population with PW. Given the poor availability of treatment, a quadrivalent vaccine for men may have significant benefit.

Abstract
BACKGROUND Few data on the effect of human papillomavirus (HPV) infection on human immunodeficiency virus (HIV) acquisition are available. METHODS HIV-seronegative, sexually active, 18-24-year-old Kenyan men participating in a randomized trial of male circumcision provided exfoliated penile cells from 2 anatomical sites (glans/coronal sulcus and shaft) at baseline. The GP5+/6+ polymerase chain reaction assay ascertained a wide range of HPV DNA types at the baseline visit. The risk of HIV infection was estimated using Kaplan-Meier methods and hazard ratios from proportional hazards models. RESULTS Of 2168 uncircumcised men with baseline HPV data, 1089 (50%) were positive for HPV DNA. The cumulative incidence of HIV infection by 42 months was 5.8% (95% confidence interval [CI], 3.6%-7.9%) among men with HPV-positive glans/coronal sulcus specimens, versus 3.7% [95% CI, 1.8%-5.6%] among men with HPV-negative glans/coronal sulcus specimens (P = .01). Controlling for subsequent circumcision status, baseline herpes simplex virus type 2 serostatus, and sexual and sociodemographic risk factors, the hazard ratio for HIV infection among men with HPV-positive glans/coronal sulcus specimens was 1.8 (95% CI, 1.1-2.9), compared with men with HPV-negative glans/coronal sulcus specimens. CONCLUSION The results suggest an independent increased risk of HIV seroconversion among HPV-positive men. If this finding is confirmed in other studies, HPV prevention could be another tool for HIV prevention.

Abstract
BACKGROUND No studies have examined human papillomavirus (HPV) infections among couples early in their sexual relationships when transmission is most likely. Our objective was to describe the distribution of HPV infections among recently formed couples, using the partnership as the unit of analysis. METHODS Women aged 18-24 years attending a university or junior college in Montreal enrolled in a longitudinal study with their new male partners. Self-collected vaginal swabs and clinician-collected swabs from the penis and scrotum were tested for 36 HPV genotypes. Participants self-reported sexual behavior in computerized questionnaires. We analyzed patterns of genital HPV infection in 263 couples using data obtained at enrollment. RESULTS Couples had engaged in vaginal sex for a median of 3.9 months. HPV was detected in 64% (169/263) of couples. In 41% (109/263), both partners harbored the same HPV type-nearly 4 times more than expected if HPV status of partners were uncorrelated. There were 583 type-specific HPV infections among 169 couples for whom at least one partner was infected. Of these, 42% were of the same type for both partners (95% confidence interval = 36%-47%). This rose from 25% among those engaging in vaginal sex for less than 2 months to 68% among those at 5 to 6 months. CONCLUSIONS Although HPV is common, detection of the same type in persons initiating a sex relationship would be rare given type-specific prevalence rates. The high degree of concordance we found suggests a high probability of transmission.

Abstract
INTRODUCTION Genital Human Papillomavirus (HPV) infection is the most commonly occurring sexually transmitted viral infection in humans. HPV is a wide family of DNA viruses, which may cause benign skin and mucosal tumors (genital, anal, or oral warts), intraepithelial neoplasias, and/or malignant cancers in different organs. Women are more susceptible to the oncogenic effect of HPVs, mostly at the genital site on the uterine cervix. AIMS This review analyzes the impact of: (i) genital warts (GWs) and their treatment; (ii) HPV-related genital, oral, and anal precancerous lesions on women's sexual function. METHODS A Medline search was carried out. Search terms were HPV, GWs, intraepithelial neoplasia, cervical cancer, anal cancer, oral cancer, epidemiology, HPV risk factors, sexual dysfunctions, desire disorders, arousal disorders, dyspareunia, vulvar vestibulitis, vulvodynia, orgasmic difficulties, sexual repertoire, couple sexual problems, depression, anxiety, pap smear, screening program, therapy, and vaccines. MAIN OUTCOME MEASURES Sexual consequences of HPV infection in women, specifically GWs and intraepithelial HPV-related neoplasia. RESULTS Psychosexual vulnerability increases with number of recurrences of HPV infections. Depression, anxiety, and anger are the emotions most frequently reported. However, to date, there is no conclusive evidence of a specific correlation between HPV infection and a specific female sexual disorder. The relationship between HPV and vulvar vestibulitis/vulvodynia-related dyspareunia seems not to be direct. Counseling problems, the role of anti-HPV vaccine, and the concept of the high-risk partner are discussed. The reader is offered a practical approach with clinically relevant recommendations that may prove useful in his/her daily practice when dealing with HPV-infected women and couples. CONCLUSION The evidence of psychosexual consequences of HPV-related GWs and intraepithelial lesions is limited. Specific research on the sexual impact of GWs and intraepithelial HPV-related lesion in women is urgently needed.

Abstract
Persistent human papillomavirus (HPV) infection is the central cause in the development of anogenital warts, precancers and cancers of uterine cervix, and a major factor in the genesis of other malignancies of the lower anogenital and upper aerodigestive tracts. The burden of disease carries very high medical, financial and psychosocial costs. The role of prophylactic HPV vaccines in reducing the burden of disease is discussed in light of the results of multiple randomized, controlled trials conducted worldwide in thousands of young females. The review discusses some of the issues that are still unknown, with respect to long-term vaccine performance, challenges to be overcome to achieve universal, mass prophylactic HPV vaccination, as well as the potential impact of the vaccines on primary screening for, and management of, HPV-related anogenital infection and disease.
