Abstract
Screening for cervical cancer precursors by cytology has been very successful in countries where adequate resources exist to ensure high quality and good coverage of the population at risk. Mortality reductions in excess of 50% have been achieved in many developed countries; however the procedure is generally inefficient and unworkable in many parts of the world where the appropriate infrastructure is not achievable. A summary and update of recently published meta-analyses and systematic reviews on four possible clinical applications of human papillomavirus (HPV) DNA testing is provided in this article: (1) triage of women with equivocal or low-grade cytological abnormalities; (2) follow-up of women with abnormal screening results who are negative at colposcopy/biopsy; (3) prediction of the therapeutic outcome after treatment of cervical intraepithelial neoplasia (CIN), and most importantly (4) primary screening HPV DNA test, solely or in combination with Pap smear to detect cervical cancer precursors. There are clear benefits for the use of HPV DNA testing in the triage of equivocal smears, low-grade smears in older women and in the post-treatment surveillance of women after treatment for CIN. However, there are still issues regarding how best to use HPV DNA testing in primary screening. Primary screening with Hybrid Capture((R)) 2 (HC2) generally detects more than 90% of all CIN2, CIN3 or cancer cases, and is 25% (95% CI): 15-36%) relatively more sensitive than cytology at a cut-off of abnormal squamous cells of undetermined significance (ASC-US) (or low-grade squamous intraepithelial lesions (LSIL) if ASC-US unavailable), but is 6% (95% CI: 4-7%) relatively less specific. Several approaches are currently under evaluation to deal with the lower specificity of HPV DNA testing as associated with transient infection. These include HPV typing for HPV-16 and -18/45, markers of proliferative lesions such as p16 and mRNA coding for the viral E6 and/or E7 proteins, with a potential clinical use recommending more aggressive management in those who are positive. In countries where cytology is of good quality, the most attractive option for primary screening is to use HPV DNA testing as the sole screening modality with cytology reserved for triage of HPV-positive women. Established cytology-based programmes should also be gradually moving towards a greater use of HPV DNA testing to improve their efficacy and safely lengthen the screening interval. The greater sensitivity of HPV DNA testing compared to cytology argues strongly for using HPV DNA testing as the primary screening test in newly implemented programmes, except where resources are extremely limited and only programmes based on visual inspection are affordable. In such countries, use of a simple HPV DNA test followed by immediate 'screen and treat' algorithms based on visual inspection in those who are HPV-positive are needed to minimise the number of visits and make best use of limited resources. A review of studies for visual inspection methods is presented. The fact that HPV is a sexually transmitted infection may lead to anxiety and concerns about sexual relationships. These psychosocial aspects and the need for more information and educational programmes about HPV are also discussed in this article.

Abstract
For a better understanding of the consequences of recurrent chromosomal alterations in cervical carcinomas, we integrated genome-wide chromosomal and transcriptional profiles of 10 squamous cell carcinomas (SCCs), 5 adenocarcinomas (AdCAs) and 6 normal controls. Previous genomic profiling showed that gains at chromosome arms 1q, 3q, and 20q as well as losses at 8q, 10q, 11q, and 13q were common in cervical carcinomas. Altered regions spanned multiple megabases, and the extent to which expression of genes located there is affected remains unclear. Expression analysis of these previously chromosomally profiled carcinomas yielded 83 genes with significantly differential expression between carcinomas and normal epithelium. Application of differential gene locus mapping (DIGMAP) analysis and the array CGH expression integration tool (ACE-it) identified hotspots within large chromosomal alterations in which gene expression was altered as well. Chromosomal gains of the long arms of chromosome 1, 3, and 20 resulted in increased expression of genes located at 1q32.1-32.2, 3q13.32-23, 3q26.32-27.3, and 20q11.21-13.33, whereas a chromosomal loss of 11q22.3-25 was related to decreased expression of genes located in this region. Overexpression of DTX3L, PIK3R4, ATP2C1, and SLC25A36, all located at 3q21.1-23 and identified by DIGMAP, ACE-it or both, was confirmed in an independent validation sample set consisting of 12 SCCs and 13 normal ectocervical samples. In conclusion, integrated chromosomal and transcriptional profiling identified chromosomal hotspots at 1q, 3q, 11q, and 20q with altered gene expression within large commonly altered chromosomal regions in cervical cancer.

Abstract
We previously showed that silencing of TSLC1, recently renamed CADM1, is functionally involved in high-risk HPV-mediated cervical carcinogenesis. CADM1 silencing often results from promoter methylation. Here, we determined the extent of CADM1 promoter methylation in cervical (pre)malignant lesions and its relation to anchorage-independent growth and gene silencing to select a CADM1-based methylation marker for identification of women at risk of cervical cancer. Methylation-specific PCRs targeting three regions within the CADM1 promoter were performed on high-risk HPV-containing cell lines, PBMCs, normal cervical smears, and (pre)malignant lesions. CADM1 protein expression in cervical tissues was analysed by immunohistochemistry. All statistical tests were two-sided. Density of methylation was associated with the degree of anchorage-independent growth and CADM1 gene silencing in vitro. In cervical squamous lesions, methylation frequency and density increased with severity of disease. Dense methylation (defined as >or= 2 methylated regions) increased from 5% in normal cervical samples to 30% in CIN3 lesions and 83% in squamous cell carcinomas (SCCs) and was significantly associated with decreased CADM1 protein expression (p < 0.00005). The frequency of dense methylation was significantly higher in >or= CIN3 compared with <or= CIN1 (p = 0.005), as well as in SCCs compared with adenocarcinomas (83% versus 23%; p = 0.002). Detection of dense CADM1 promoter methylation will contribute to the assembly of a valuable marker panel for the triage of high-risk HPV-positive women at risk of >or= CIN3.

Abstract
Staging by sentinel node (SN) biopsy is the standard procedure for clinically node-negative breast cancer patients. Intra-operative analysis of the SN allows immediate axillary lymph node (ALN) dissection in SN positive patients, but a quick, reliable and reproducible method is lacking. We tested the suitability of a quantitative cytokeratin 19 (CK19) mRNA one step nucleic acid amplification (OSNA#) technique (OSNA-CK19) for intra-operative SN analysis. OSNA-CK19 involves a short manual sample preparation step and subsequent fully automated amplification of CK19 mRNA based on reverse transcription loop-mediated isothermal amplification, with results available within 30–40 min. OSNA-CK19 was compared to histological staining (Hematoxylin&Eosin and CAM5.2 and CK19 immunostaining) of 346 frozen ALNs from 32 breast cancer patients, using half of the lymph node for each method. 267 samples were negative and 61 positive by both methods. Three samples were histology positive and OSNA-CK19 negative. Fifteen samples were histology negative and OSNA-CK19 positive, 11 of which had copy numbers close to the cut-off level of OSNA-CK19. Seven of these 15 samples were RT-PCR positive for epithelial markers and/or showed CK19 protein expression by Western blot suggesting the presence of tumor deposits in the lymph node part investigated by OSNA-CK19. Concordance with histology was 94.8%, and 96.8% after exclusion of the latter 7 discordant cases. Sensitivity was 95.3% and specificity was 94.7% before and 97.1% after discordant case investigation. Our results indicate that OSNA-CK19 can potentially be useful in an intra-operative clinical setting to detect SN tumor involvement in breast cancer patients.

Abstract
PURPOSE Inhibition of the apoptosis cascade is an important cause of therapy resistance in diffuse large B-cell lymphomas (DLBCL). In this study, we investigated possible mechanisms and expression levels of apoptosis-related genes in the apoptosis pathway that may be responsible for differences in chemotherapy sensitivity between DLBCL patients. EXPERIMENTAL DESIGN Twenty-eight DLBCL patient samples were investigated for their expression levels of apoptosis-related genes using reverse transcription-multiplex ligation-dependent probe amplification analysis. Functional analysis of the intrinsic, caspase-9-mediated pathway was done using fluorescence-activated cell sorting analysis, Western blot analysis, and immunohistochemistry. RESULTS Two DLBCL groups were identified: one with low expression levels of both proapoptotic and antiapoptotic genes and one group with high expression levels of these genes. DLBCL with high expression levels of proapoptotic and antiapoptotic genes frequently seemed to be refractory to clinical chemotherapy. Functional analysis in these latter DLBCL samples and DLBCL cell lines with comparable expression profiles revealed high levels of spontaneous caspase-9 activity without induction of apoptosis, indicating disruption of the apoptosis pathway downstream of caspase-9 activation. This disruption of the apoptosis pathway could be restored using a small-molecule XIAP antagonist. CONCLUSIONS We conclude that the intrinsic, caspase-9-mediated apoptosis pathway is constitutively activated in part of chemotherapy-refractory DLBCL with concomitant downstream inhibition of the convergence apoptosis pathway and that inhibition of XIAP might be an alternative therapy for chemotherapy-refractory DLBCL.

Abstract
To evaluate the prognostic significance of clinicobiologic and pathological features in angioimmunoblastic T-cell lymphoma (AITL), 157 AITL patients were retrieved from the GELA LNH87-LNH93 randomized clinical trials. One hundred forty-seven patients received a cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)-like regimen with intensified courses in half of them. Histologically, 41 cases were classified as "rich in large cells" and 116 as "classic" (including 19 rich in epithelioid cells, 14 rich in clear cells, and 4 with hyperplastic germinal centers). Sixty-two cases were scored for CD10 and CXCL13 expression according to the abundance of positive lymphoid cells. Median age was 62 years, with 81% advanced stage, 72% B symptoms, 65% anemia, 50% hypergammaglobulinemia, and 66% elevated LDH. Overall 7-year survival was 30%. In multivariate analysis, only male sex (P = .004), mediastinal lymphadenopathy (P = .041), and anemia (P = .042) adversely affected overall survival. Increase in large cells and high level of CD10 and CXCL13 did not affect survival. Intensive regimen did not improve survival. In conclusion, AITL is a morphologically heterogeneous T-cell lymphoma commonly expressing CXCL13 and CD10 and carrying few prognostic factors. It portends a poor prognosis even when treated intensively. However, AITL is not always lethal with 30% of patients alive at 7 years.

Abstract
--Infection with high-risk genital Human papillomavirus (hrHPV) is necessary for the development of cervical cancer and its early stages. --Although it is widely accepted that infection with hrHPV is sexually transmitted, insight into the clinical manifestations of hrHPV infection in men is limited. --Flat penile lesions may be the hrHPV reservoir in men. --Their limited visibility with the naked eye explains why flat penile lesions may escape the attention of both the carrier and the clinician. The lesions can be visualized by the application of an acetic acid solution. They should be distinguished from papillary abnormalities occurring close to the frenulum and the pearl-shaped penile papulae around the coronary sulcus that do not accompany HPV. --Only flat penile lesions are associated with high numbers of HPV copies and therefore contribute to the sexual viral spread. --The use of condoms protects against sexual transmission of HPV.

Abstract
--Each year, 600-700 women in the Netherlands are diagnosed with cervical cancer. Over the last 10 years, an average of 250 women have died annually due to cervical cancer. --Gardasil, the first vaccine for Human papillomavirus (HPV), was recently approved in Europe for the prevention of cervical cancer. --The availability of a vaccine for HPV prompts the question whether it should be included in the Dutch National Immunisation Programme. --At the end of 2006, the Medicines Evaluation Board, the Health Council of the Netherlands and the Centre for Infectious Disease Control of the National Institute for Public Health and the Environment organised a workshop for experts in the field to answer that question. --The HPV vaccine provides protection against HPV-16 and HPV-18, which cause approximately 70% of cervical cancers. --Because the efficacy of vaccination is only evident after many years, preserving good participation in the screening programme is essential. --The current screening could be improved by introducing an HPV test combined with self-sampling for women who do not participate in screening. --Vaccination is unarguably an important development. However, there are still several unanswered questions regarding vaccination and its actual protection, duration of protection, long-term safety and cost-effectiveness. --April 1st, 2008, the Health Council of the Netherlands had recommended including HPV vaccination in the National Immunisation Programme.

Abstract
BACKGROUND Smoking increases the risk of squamous-cell carcinoma of the cervix, but it is not clear whether smoking increases the risk of acquisition or persistence of human papillomavirus (HPV) infection. METHODS Information on smoking was collected from 10 areas in four continents among population-based, age-stratified random samples of women aged 15 years or older. HPV testing was performed using PCR-based enzyme immunoassay. Unconditional logistic regression was used to estimate odds ratios (OR) and corresponding 95% confidence intervals (CI) of being HPV-positive by smoking habits, adjusted for age and lifetime number of sexual partners. RESULTS Ten thousand five hundred and seventy-seven women (mean age 41.4 years) were included. Among current smokers, the risk of being HPV-positive increased with smoking intensity, after allowing for lifetime number of sexual partners: ORs for <5, 5-14 and >/=15 cigarettes per day were 1.21 (95% CI 0.95-1.54), 1.39 (95% CI 1.04-1.87) and 2.01 (95% CI 1.32-3.08), respectively, as compared with never-smokers. The risk among former smokers (OR = 0.95, 95% CI 0.73-1.23) was similar to that among never-smokers. Analyses stratified by lifetime number of sexual partners showed a significant trend in risk only for women with one lifetime sexual partner. CONCLUSIONS Our study suggests that current, though not former, smoking is associated with an increased prevalence of HPV, after allowance for sexual covariates. Among current smokers, HPV prevalence increased with smoking intensity, but a clear dose-response relationship was exclusively seen among women who declared one lifetime sexual partner.

Abstract
Although high-risk human papillomavirus (HPV) infection plays a major role in the development of cervical cancer, additive oncogenic events are involved as well. One key event involves increased activity of telomerase resulting from a deregulated expression of its catalytic subunit hTERT. Our previous microcell-mediated chromosome transfer studies revealed that introduction of human chromosome 6 in the HPV16-immortalized keratinocyte cell line FK16A and in the HPV16-containing cervical cancer cell line SiHa induced growth arrest, resulting from a repression of hTERT mRNA expression and telomerase activity. Here, this model was used to analyze expression profiles associated with hTERT deregulation in HPV-transformed cells. Microarray expression analysis of 12 FK16A/chromosome 6 hybrids, 4 of which were negative for endogenous hTERT and 8 of which were positive for endogenous hTERT, resulted in the identification of 164 differentially expressed genes. Differential expression of a selection of 5 genes was verified by real-time RT-PCR. Of these 164 genes, 32 were also differentially expressed in other HPV transformed cells with deregulated hTERT. For 2 of these genes, encoding AQP3 and MGP, altered expression in hTERT positive cervical carcinomas was confirmed by real-time RT-PCR and immunohistochemistry, respectively. Moreover, increased MGP protein expression was significantly more frequent in high-grade cervical premalignant lesions with elevated hTERT mRNA expression compared to those without. In summary, we identified 32 candidate biomarkers for deregulated hTERT mRNA expression, which may enable the identification of cervical premalignant lesions that are at highest risk to progress to invasive cancer.

Abstract
beta-Papillomaviruses (PV) seem to be involved in the pathogenesis of cutaneous squamous cell carcinoma and its early stage actinic keratosis. In this study, typing was extended of a previously described consensus primer-mediated beta- and gamma-cutaneous HPV PCR method followed by reverse-line-blotting (BGC-PCR/RLB) to detect all 25 known beta-PV and to examine their prevalence in actinic keratosis. The typing format of the BGC-PCR assay was extended by adding hybridization probes of six beta-PV (HPV 75, 76, 80, 92, 93, and 96) to the RLB system. Subsequently, tumor and normal skin tissues were collected from 75 patients with actinic keratosis, allowing typing for a total of 25 beta- and 5 gamma-types. The analytical sensitivity was between 10 copies (HPV 75, 80, 92, 93, and 96) and 100 copies (HPV 76). Except for that of HPV 76, none of the added probes showed any cross-hybridization with other beta-HPV. HPV DNA was detected in 45% of actinic keratosis and in 33% of normal skin by BGC-PCR, and at least one of the six added beta-types was present in 19% of actinic keratoses and in 13% of normal skin. Six beta-HPV types were added successfully to the typing format of the BGC-PCR/RLB system. The potential role of these types in the development of non-melanoma skin cancer awaits further studies.

Abstract
GOAL To determine type-specific seroprevalence of herpes simplex viruses (HSV-1 and HSV-2) and HSV-2 risk factors. STUDY DESIGN Six-hundred fifty eight middle-aged control women (hospital-based in 4 of 6 countries) from a multicenter cervical cancer case-control study participated from 1985 to 1997. Type-specific serum IgG antibodies against HSV-1 and HSV-2 were detected with Western Blot. RESULTS HSV-1 seroprevalence was 89% to 100% everywhere except Thailand (51%). HSV-2 seroprevalence ranged from 9% (Spain) to 57% (Colombia), and was independently associated with having >or=2 lifetime sexual partners overall [Odds ratio (OR), 2.1; 95% confidence interval (CI) 2.5-3.1], and in Morocco (OR, 2.7; 95% CI, 1.2-6.1) and Thailand (OR, 4.4; 95% CI, 1.3-15.4), and with being unmarried in Colombia, Peru, Spain, but not significantly in Mali. Women whose male partner's sexual debut was <or=17 years had a higher HSV-2 risk (OR, 4.3 95% CI, 1.3-13.7). CONCLUSIONS HSV-2 seroprevalence in middle-aged women varied over 4-fold and was associated with riskier sexual behaviors in women and their male partners.

Abstract
Human papillomavirus type 16 (HPV16) plays a role in the development of a subgroup of head and neck squamous cell carcinomas (HNSCC). However, uncertainty exists about the true impact of HPV in this tumor type as conflicting reports have been published with prevalence rates from 0 to 100%. We aimed to find a detection algorithm of a biologically and thus clinically meaningful infection, applicable for high-throughput screening of frozen and formalin-fixed paraffin embedded (FFPE) specimens. By considering detection of HPV E6 oncogene expression in frozen biopsies as gold standard for a meaningful HPV infection, the value of several assays was evaluated on FFPE tumor specimens and sera of 48 HNSCC patients. The following assays were evaluated on FFPE tissue samples: HPV DNA general primer (GP)5+/6+ PCR, viral load analysis, HPV16 DNA FISH detection, HPV16 E6 mRNA RT-PCR, p16 immunostaining, and on corresponding serum samples detection of antibodies against the HPV16 proteins L1, E6 and E7. Comparing single assays on FFPE tissue samples detection of E6 expression by RT-PCR was superior, but application remains at present limited to HPV16 detection. Most suitable algorithm with 100% sensitivity and specificity appeared p16 immunostaining followed by GP5+/6+ PCR on the p16-positive cases. We show that clinically meaningful viral HPV infections can be more reliably measured in FFPE HNSCC samples in a standard and high throughput manner, paving the way for prognostic and experimental vaccination studies, regarding not only HNSCC, but possibly also cancer types with HPV involvement in subgroups such as penile and anal cancer.

Abstract
BACKGROUND Tests for the DNA of high-risk types of human papillomavirus (HPV) have a higher sensitivity for cervical intraepithelial neoplasia grade 3 or worse (CIN3+) than does cytological testing, but the necessity of such testing in cervical screening has been debated. Our aim was to determine whether the effectiveness of cervical screening improves when HPV DNA testing is implemented. METHODS Women aged 29-56 years who were participating in the regular cervical screening programme in the Netherlands were randomly assigned to combined cytological and HPV DNA testing or to conventional cytological testing only. After 5 years, combined cytological and HPV DNA testing were done in both groups. The primary outcome measure was the number of CIN3+ lesions detected. Analyses were done by intention to treat. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN20781131. FINDINGS 8575 women in the intervention group and 8580 in the control group were recruited, followed up for sufficient time (> or =6.5 years), and met eligibility criteria for our analyses. More CIN3+ lesions were detected at baseline in the intervention group than in the control group (68/8575 vs 40/8580, 70% increase, 95% CI 15-151; p=0.007). The number of CIN3+ lesions detected in the subsequent round was lower in the intervention group than in the control group (24/8413 vs 54/8456, 55% decrease, 95% CI 28-72; p=0.001). The number of CIN3+ lesions over the two rounds did not differ between groups. INTERPRETATION The implementation of HPV DNA testing in cervical screening leads to earlier detection of CIN3+ lesions. Earlier detection of such lesions could permit an extension of the screening interval.

Abstract
PURPOSE Human papillomavirus (HPV) infections are suggested to be involved in the development of penile squamous cell carcinoma (SCC), but comprehensive studies to define the association are limited. Therefore, we performed molecular and serologic analyses for a broad spectrum of HPV types on a large series of 83 penile SCCs, and we compared serological findings to those of age-matched male controls (N = 83). METHODS Penile SCCs were subjected to detection and typing assays for mucosal and cutaneous HPVs and to subsequent, type-specific viral load and viral gene expression assays. Sera of patients and of controls were analyzed for type-specific mucosal and cutaneous HPV L1, E6, and/or E7 antibodies using bead-based, multiplex serology. RESULTS HPV DNA of mucosal and/or cutaneous types was found in 46 of 83 (55%) penile SCCs. HPV16 was the predominant type, appearing in 24 (52%) of 46 of penile SCCs. The majority of HPV16 DNA-positive SCCs (18 of 24; 75%) demonstrated E6 transcriptional activity and a high viral load. Additionally, HPV16 molecular findings were strongly associated with HPV16 L1-, E6-, and E7-antibody seropositivity. Furthermore, serologic case-control analyses demonstrated that, in addition to the association of HPV16 with penile SCC, seropositivity against any HPV type was significantly more common in patients compared with in controls. HPV18 and HPV6 seropositivity were associated with HPV16-negative SCCs but were not correlated to molecular findings. CONCLUSION HPV16 is the main HPV type etiologically involved in the development of penile SCC. Although individuals who develop penile SCC show a greater prior exposure to a broad spectrum of HPV types, insufficient evidence was found to claim a role for HPV types other than HPV16 in penile carcinogenesis.

Abstract
BACKGROUND Limited data are available on whether sampling from the penile shaft or urethra increases detection of penile HPV infection in men beyond that found in the glans and coronal sulcus. METHODS Within a randomized clinical trial, a validation study of penile sampling was conducted in Kisumu, Kenya. Young men (18-24 years) were invited to provide penile exfoliated cells using prewetted Dacron swabs to determine the best site for HPV detection. beta-Globin gene PCR and HPV DNA type GP5+/6+ PCR status were ascertained from 3 anatomical sites. RESULTS A total of 98 young HIV-seronegative, uncircumcised men participated. Penile HPV prevalence varied by anatomical site: 50% in penile exfoliated cells from the glans, coronal sulcus, and inner foreskin tissue; 43% in the shaft and external foreskin tissue; and 18% in the urethra (P <0.0001). For each anatomical site, over 87% of samples were beta-globin positive. Beyond that found in the glans/coronal sulcus, urethral sampling resulted in no increase in HPV positivity and shaft sampling resulted in an additional 7.3% of overall HPV positivity. The prevalence of high-risk HPV positivity varied by anatomical site: 39% in glans/coronal sulcus, 31% in shaft, and 13% in the urethra (P <0.0001). HPV 16 was the most common type identified. DISCUSSION Penile HPV prevalence was approximately 50% among young men in Kisumu, Kenya. Urethral sampling for HPV detection in men added no sensitivity for HPV detection over that found from sampling the glans/coronal sulcus and penile shaft. These data will help inform studies on HPV transmission dynamics, and on the efficacy of HPV prophylactic vaccines on penile HPV carriage in men.

Abstract
CD4(+)CD25(hi)CTLA4(+)FoxP3(+) regulatory T cells (Treg) have been shown to maintain immune tolerance against self antigens and increased circulating frequencies have been reported in various types of cancers. Circulating invariant natural killer T-cells (iNKT) are reduced in cancer patients and low iNKT frequency is related to poor prognosis. It is not yet clear whether high Treg numbers and low iNKT cell numbers pose an increased risk for the progression of premalignant lesions or whether Treg and iNKT cell numbers are influenced by dysplasia. We therefore studied prospectively the relation between iNKT cell and Treg frequencies and the natural course of human papillomavirus type 16 (HPV16) induced pre-malignant cervical dysplasia in 82 patients who participated in a nonintervention cohort study of women with abnormal cytology. Treg frequencies were significantly increased in women who had persistent HPV16 infection. Within the HPV16 persistence group there was no difference in Treg frequencies among patients who developed a CIN3 lesion and patients who did not progress to CIN3. Furthermore, Treg frequencies were increased in patients who had detectable HPV16 E7 specific IL-2 producing T-helper cells, which suggests a causal role of HPV infection in Treg development in parallel with HPV16 specific T helper cells. No evidence was found for a role for iNKT cells in persistence of HPV16 and progression of HPV16 induced CIN lesions. However, HPV-persistence-associated Tregs may explain the inefficacy of concomitant persistence associated immunity and may contribute to subsequent progression to neoplasia.

Abstract
OBJECTIVES Better information on the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection is needed in many world areas. STUDY DESIGN Cross-sectional study of population-based samples of nonpregnant women aged 15 to 44 years in Nigeria, Colombia, Argentina, Vietnam (2 areas), China, Thailand (2 areas), Korea, and Spain. 5,328 consenting women aged 15 to 44 years participated. Exfoliated cervical cells were collected and testing for CT and NG and human papillomavirus (HPV) was done using PCR-based assays. RESULTS Age-standardized CT prevalence ranged between 0.2% (95% confidence interval, CI: 0.0-0.7%) in Spain and 5.6% (95% CI: 3.4-7.8%) in Nigeria. NG ranged between 0% (with broad CIs) in several areas and 2.6% (95% CI: 1.0-4.2%) in Nigeria. Prevalence of CT in all areas combined was greater in women aged 15 to 24 (4.5; 95% CI: 3.4-5.8%) than 25 to 44 (2.6; 95% CI: 2.1-3.1%), whereas NG prevalence was similar in the 2 age groups (0.3%). The only significant risk factors were NG infection (for CT), CT infection (for NG) and infection with high-risk HPV types (for both). CONCLUSIONS The prevalence of CT and, most notably, NG was relatively low in a variety of countries. Our findings, however, do not apply to subsets of high-risk women who are likely to be underrepresented in our population-based samples.

Abstract
Given the causal relation between a persistent high-risk human papillomavirus (hrHPV) infection and the development of high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer, hrHPV testing has been advocated in addition to cytology for the detection of clinically relevant cervical lesions. HrHPV testing is thought to improve cervical screening algorithms, the management of women with cytologically equivocal smears, and the management of women treated for high grade CIN. In this chapter we discuss different methods for HPV detection and genotyping and their respective applications.

Abstract
AIMS Cervical screening, currently performed by cervical cytology, depends on the timely detection of malignant lesions for its success. The presence of high-risk human papillomavirus (hrHPV) is associated with an increased risk of subsequent high-grade cervical intra-epithelial neoplasia (CIN2/3) and cervical cancer. The aim of this study was to determine the extent to which hrHPV is present in cervical smears with a high a priori chance of being false negative (ie, in normal smears preceding CIN2/3). METHODS Archival specimens of 187 women with CIN2/3 and preceding normal conventional smears were identified retrospectively. Of these specimens, 144 (77%) had adequate cytological samples for further HPV DNA testing. RESULTS Of 144 CIN2/3 lesions, preceding normal smears showed hrHPV positivity in 80% of cases. Of the hrHPV-positive smears, 69% were upgraded cytologically at rescreening compared with 24% of hrHPV-negative smears (p<0.001). Upgrading of smears was not associated with specific hrHPV types (p = 0.217). In over 90% of cases, type concordance in smear and CIN2/3 lesion was demonstrated. CONCLUSIONS hrHPV is present in a high proportion of normal archival smears preceding CIN2/3, and false-negative cytology was highly associated with the presence of hrHPV. This supports the current notion that hrHPV testing can be used as a primary cervical screening tool. If so, hrHPV-positive cervical smears should be carefully examined for cytological abnormalities to reduce false-negative cervical cytology.
