Int J Cancer 2024; 154:1443-1454. [PMID: 38126210 DOI: 10.1002/ijc.34824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 12/23/2023]
Abstract
The cancer burden in China is increasing. We aimed to assess the time trends in the prevalence of 16 modifiable risk factors involved in lifestyle, diet, infection, and air pollution between 1997 and 2025 based on the China Health and Nutrition Survey, the Global Burden of Disease website, and publically available studies. The population attributable fraction (PAF) and its 95% uncertainty interval (UI) from 2007 to 2035 were calculated to quantify the attributable cancer burden in major 12 anatomic sites using the comparative risk assessment method, considering a 10-year lag effect. As a result, 1,559,476 cancer cases (PAF = 54.1%, 95% UI: 36.8%-65.8%) from the 12 anatomic sites were attributable to these modifiable risk factors in 2007, with lung, liver, and gastric cancer raging the top three. It was predicted that by 2035, the attributable cancer cases would reach 1,680,098 (PAF = 44.2%, 95% UI: 29.1%-55.5%), with the top three of lung, liver, and colorectal cancer. Smoking, physical inactivity, insufficient fruit consumption, HBV infection, and Helicobacter pylori infection were the most attributable risk factors in 2007, contributing to 480,352, 233,684, 215,009, 214,455, and 187,305 associated cancer cases, respectively. In 2035, the leading factors for cancer would be smoking, physical inactivity, insufficient fruit intake, HPV infection, and HBV infection, resulting in 427,445, 424,327, 185,144, 156,535, and 154,368 cancer cases, respectively. Intervention strategies should be swiftly established and dynamically altered in response to risk factors like smoking, physical inactivity, poor fruit intake, and infectious factors that may cause a high cancer burden in the Chinese population.

Electrochemical detection of human papillomavirus DNA type 16 using a pyrrolidinyl peptide nucleic acid probe immobilized on screen-printed carbon electrodes. Biosens Bioelectron 2013; 54:428-34. [PMID: 24300785 DOI: 10.1016/j.bios.2013.11.023] [Citation(s) in RCA: 104] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2013] [Revised: 10/30/2013] [Accepted: 11/06/2013] [Indexed: 11/25/2022]
Abstract
An electrochemical biosensor based on an immobilized anthraquinone-labeled pyrrolidinyl peptide nucleic acid (acpcPNA) probe was successfully developed for the selective detection of human papillomavirus (HPV) type 16 DNA. A 14-mer acpcPNA capture probe was designed to recognize a specific 14 nucleotide region of HPV type 16 L1 gene. The redox-active label anthraquinone (AQ) was covalently attached to the N-terminus of the acpcPNA probe through an amide bond. The probe was immobilized onto a chitosan-modified disposable screen-printed carbon electrode via a C-terminal lysine residue using glutaraldehyde as a cross-linking agent. Hybridization with the target DNA was studied by measuring the electrochemical signal response of the AQ label using square-wave voltammetric analysis. The calibration curve exhibited a linear range between 0.02 and 12.0 µM with a limit of detection and limit of quantitation of 4 and 14 nM, respectively. This DNA sensing platform was successfully applied to detect the HPV type 16 DNA from a PCR amplified (240 bp fragment of the L1 gene) sample derived from the HPV type 16 positive human cancer cell line (SiHa), and failed to detect the HPV-negative c33a cell line. The sensor probe exhibited very high selectivity for the complementary 14 base oligonucleotide over the non-complementary oligonucleotides with sequences derived from HPV types 18, 31 and 33. The proposed sensor provides an inexpensive tool for the early stage detection of HPV type 16, which is an important biomarker for cervical cancer.

Abstract
BACKGROUND Human papillomavirus (HPV) prevalence in oropharyngeal squamous cell cancer (SCC) remains variable and studies have estimated that up to 60% may be positive. METHODS One hundred five treatment-naïve oropharyngeal SCC patients were included. HPV genotyping was done by consensus polymerase chain reaction (PCR) and reverse line-blot hybridization assay. HPV prevalence was co-related with sex, age, tobacco consumption, alcohol use, and high-risk sexual behavior. RESULTS HPV prevalence was 22.8%. No significant associations were seen between tobacco or alcohol consumption with HPV status. The mean number of lifetime sexual partners and indulgence in high-risk sexual behavior was significantly more in patients who are HPV positive. There were no significant associations between the 2 groups with respect to the stage of the tumor. CONCLUSION Results of this study confirms that patients who are HPV positive are younger, and with high-risk sexual behavior. We did not find any impact of smoking and alcohol consumption on HPV status.

Abstract
Background Human papillomaviruses are the most common sexually transmitted infections, and genital warts, caused by HPV-6 and 11, entail considerable morbidity and cost. The natural history of genital warts in relation to HIV-1 infection has not been described in African women. We examined risk factors for genital warts in a cohort of high-risk women in Burkina Faso, in order to further describe their epidemiology. Methods A prospective study of 765 high-risk women who were followed at 4-monthly intervals for 27 months in Burkina Faso. Logistic and Cox regression were used to identify factors associated with prevalent, incident and persistent genital warts, including HIV-1 serostatus, CD4+ count, and concurrent sexually transmitted infections. In a subset of 306 women, cervical HPV DNA was tested at enrolment. Results Genital wart prevalence at baseline was 1.6% (8/492) among HIV-uninfected and 7.0% (19/273) among HIV-1 seropositive women. Forty women (5.2%) experienced at least one incident GW episode. Incidence was 1.1 per 100 person-years among HIV-uninfected women, 7.4 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count >200 cells/μL and 14.6 per 100 person-years among HIV-1 seropositive women with a nadir CD4+ count ≤200 cells/μL. Incident genital warts were also associated with concurrent bacterial vaginosis, and genital ulceration. Antiretroviral therapy was not protective against incident or persistent genital warts. Detection of HPV-6 DNA and abnormal cervical cytology were strongly associated with incident genital warts. Conclusions Genital warts occur much more frequently among HIV-1 infected women in Africa, particularly among those with low CD4+ counts. Antiretroviral therapy did not reduce the incidence or persistence of genital warts in this population.

Abstract
BACKGROUND Cervical cancer has a major impact on developing countries, where screening programs are not well established or effective. AIM This study aims to investigate Human papillomavirus (HPV) 6, 11 and 18 expression in cervical biopsies by immunohistochemistry, (IHC) followed by typing of high-risk HPV 16 and 18 in high-grades by polymerase chain reaction (PCR). SETTINGS AND DESIGN During the study period of six months, 30 biopsy samples were obtained from patients attending various gynecology clinics in and around Trichy District, Tamil Nadu, between January and June 2009. MATERIALS AND METHODS The ecto- and endoscopic biopsy specimens of the cervix were fixed in 10% buffered formalin; routine paraffin sections were taken for processing and stained with hematoxylin and eosin. The samples were graded as Normal cervicitis, Cervical intraepithelial neoplasia (CIN) I, II, III, and squamous cell carcinoma (SCC), for original diagnosis by pathologists. The extra sections were studied for the expression of HPV 6, 11 and 18 by immunohistochemistry and HPV DNA 16 and18 by PCR. RESULTS Out of thirty samples, 15 expressed positive and 15 negative for HPV marker. Twenty-seven cases of cervical gradings have been categorized into high grade CIN II/III, SCC (23) and low grade CIN I (4). The high grades were subjected to PCR for high-risk typing. The results revealed that 15 cases were positive for HPV genotype 16 and eight cases for HPV genotype 18. The prevalence of HPV infection was found to be higher in women aged between 50 and 59. CONCLUSION This study reveals a significant detection of HPV in the South Indian suspected individuals, by the use of advanced techniques such as IHC and PCR.

Abstract
Strong epidemiologic and molecular data now support the conclusion that human papillomavirus (HPV) infection is responsible for a distinct form of head and neck squamous cell carcinoma (HNSCC), independent from the traditional risk factors of tobacco and alcohol use. Patients with HPV-positive HNSCC have a different clinical presentation and better clinical outcomes than those with HPV-negative HNSCC. A diagnosis of HPV-positive HNSCC is associated not only with therapeutic relevance, but also has important implications for future prevention and screening strategies.

Abstract
The prevalence of human papillomavirus (HPV) in paired cervical scrape and urine specimens from 144 women attending a clinic for genitourinary medicine was determined by polymerase chain reaction (PCR) and nested PCR, using degenerate and general primer pairs localized within the L1 region. HPV typing was by restriction fragment length polymorphism (RFLP), type-specific PCR (HPV 6, 11, 16, 18, 33), and partial DNA sequencing of PCR products. HPV DNA was detected in 114 (84%) women. HPV DNA was detected in the specimens of 58 patients after amplification with MY09/MY11 primers and in a further 54 patients after nested PCR with the GP5+/GP6+ primers. A total of 106/136 (78%) of women had HPV DNA positive cervical scrapes and 89 (65%) had HPV DNA positive urine specimens. Both the urine and cervical specimens of 81 women were positive. In 25 women HPV DNA was detected in the cervical specimen only, and in 8 women HPV DNA was detected in the urine specimens only. A total of 108 specimens from 75 patients were typed. For 33 patients HPV typing was achieved in both the cervical and the urine specimens and 19 women had identical types in paired specimens. Multiple HPV infections could be detected in 15 (20%) of 75 women where either the cervical and urine specimen or both of the specimens could be typed. More then one HPV type was found in 8 specimens and from multiple sites (cervix and urinary tract) in the same patients on 7 occasions. The results of this study indicate that the detection of HPVs in the urogenital tract can be maximised through the testing of both cervical scrapes and urine specimens in conjunction with the use of a nested PCR to increase the sensitivity of HPV DNA detection. Also, urine cannot be a direct substitute for a cervical scrape as different HPV types are often detected in the urine compared with those detected in the cervix.

Abstract
BACKGROUND Human papillomaviruses (HPV) are known to cause cancers of the cervix and other anogenital tract sites. Molecular biology has provided some evidence as to the specific mechanisms involved in the HPV-related carcinogenesis. Epidemiologic and molecular biology studies have also suggested that HPV infection may be associated with cancers of the head and neck. METHODS This review summarizes the biology of HPV and its potential etiologic role in head and neck cancer. Published reports were used to determine the prevalence of HPV in benign, precancerous, and neoplastic lesions of the oral cavity, pharynx, and larynx. The prevalence was also examined by head and neck site, HPV type, and method of HPV detection. In addition, the occurrence of HPV in normal head and neck tissue, epidemiologic factors related to HPV infection, and clinical implications are discussed. RESULTS Overall, the frequency of HPV in benign and precancerous lesions ranged from 18.5% to 35.9%, depending upon the detection methodology. Based upon the most sensitive method of detection, polymerase chain reaction (PCR), the overall prevalence of HPV in head and neck tumors was 34.5% (416 of 1205 tumors). The majority of HPV-positive tumors contained the "high risk" HPV types 16 (40.0%) and 18 (11.9%). Among head and neck sites, HPV was most often detected in tumors of the oral cavity (59%), followed by the pharynx (43%), and larynx (33%). The frequency of HPV positivity in oral samples from healthy individuals ranged from 1% to 60%. A limited number of descriptive and analytic epidemiologic studies have indicated that age (<60 years) and sex (male) were associated with the presence of HPV in the tumor, whereas tobacco and alcohol use were not. The relationship between HPV and survival is unclear, with few comprehensive studies currently available. CONCLUSIONS The prevalence of HPV, particularly the high-risk types, suggests a potential etiologic role for the virus in head and neck cancer. Molecular biology has provided important data on the interaction of the HPV oncoproteins with genes important in cell cycle control. Nonetheless, more basic research is needed to describe the physical state of the virus in a variety of cell types and the interaction with other genes. In addition, epidemiologic research is required to further understand the association between HPV and demographic and other risk factors as well as possible routes of transmission. Finally, much work is warranted to provide a definitive assessment of the prognostic significance of HPV in head and neck cancer.

Abstract
AIMS To evaluate different hybridisation techniques to detect and type human papillomavirus (HPV) DNAs amplified by consensus primer polymerase chain reaction (PCR) in biopsy and cytological specimens. METHODS A hybrid capture-immunoassay in microtitre wells was performed to detect HPV sequences amplified by PCR and typed by specific oligoprobes. Consensus primers were used to amplify a sequence within the L1 open reading frame, and direct digoxigenin labelling of amplified products was performed during the amplification reaction. The amplified product was separately hybridised with six biotinylated type specific probes (HPV6, 11, 16, 18, 31, and 33); hybrids were then captured into streptavidin coated microtitre wells and detected by a spectrophotometer as an ELISA using antidigoxigenin Fab fragment labelled with peroxidase and a colorimetric substrate. The results were compared with the dot-blot immunoassay used to detect and type PCR amplified HPV DNA sequences. Consensus primers were used to generate the same unlabelled PCR product; digoxigenin labelled type specific probes for HPV6, 11, 16, 18, 31, and 33 were used and hybrids visualised by colorimetric immunoenzymatic reaction. Thirty nine biopsy specimens and 31 cytological samples were tested by the PCR-ELISA and by standard PCR followed by dot-blot hybridisation. RESULTS The PCR-ELISA proved to be more sensitive than standard PCR with dot-blot hybridisation typing. All samples positive for HPV-DNA in standard PCR with dot-blot hybridisation method were confirmed positive by the PCR-ELISA assay; however, seven samples were positive only by PCR-ELISA. CONCLUSIONS The PCR-ELISA assay, which can be performed in one day, is easily standardised and therefore seems to be a practical, sensitive, and reliable diagnostic tool for the detection and typing of HPV genomes in biopsy and in cytological specimens in the routine diagnostic laboratory.

Abstract
BACKGROUND Human papillomaviruses (HPV) are now considered etiologic agents of cancer of the uterine cervix. Adjunctive diagnostic procedures for the detection of HPV infection could increase the sensitivity of primary and secondary screening of cervical cancer. HPV testing could also improve the specificity of screening programs resulting in avoidance of overtreatment and saving of costs for confirmatory procedures. OBJECTIVES To review the rationale of HPV testing in genital diseases and the potential applications of HPV DNA detection methods for clinical and epidemiological purposes. RESULTS Progression of HPV infection is associated with the persistence of HPV infection, involvement of high-risk HPV types, high HPV viral load in specimens, integration of viral DNA and possibly the presence of cofactors. The design of HPV diagnostic tests will need to take into account these parameters of disease progression. HPV DNA detection techniques based on signal-amplification are standardized, commercially available and detect several high-risk HPV types. They increase the sensitivity of screening for high-grade and low-grade lesions. Although they may yield false-negative results in the presence of significant HPV-related disease, new test formats could resolve this weakness. Amplification techniques are ideal instruments for epidemiologic purposes since they minimize misclassification of HPV infection status and allow for the detection of low viral burden infections. They are currently not readily applicable to diagnostic laboratories. CONCLUSIONS Before recommending HPV testing, prospective trials of untreated LSIL with HPV testing as well as the determination of the efficacy and cost-effectiveness of novel HPV tests, need to be completed.

Abstract
We developed a sensitive chemiluminescence in situ hybridization assay for detection of human papillomavirus (HPV) DNA for objective and semiquantitative evaluation of the results. The hybridization reaction was performed using either digoxigenin-, biotin-, or fluorescein-labeled probes, visualized with alkaline phosphatase as the revealing enzyme and a highly sensitive 1,2 dioxetane phosphate as chemiluminescent substrate. The light emitted from the hybridized probes was detected, analyzed, and measured using a high-performance, low light-level imaging luminograph connected to an optical microscope and to a personal computer for quantification of the photon fluxes and for image analysis. The system operated in consecutive steps: First, hybridized specimens were recorded in transmitted light. Then the net luminescent signal was recorded, and then an overlay of the two images provided by the transmitted light and by the luminescent signal allowed the spatial distribution of the target DNA to be localized, measured, and evaluated. Biopsy specimens from different pathological conditions associated with HPV, which had previously been proved positive for HPV DNA with the polymerase chain reaction (PCR), were analysed. The chemiluminescence in situ hybridization proved sensitive and specific with digoxigenin-, biotin-, or fluorescein-labeled probes, and provided an objective evaluation of the results. The results obtained with chemiluminescence in situ hybridization were also compared with results obtained with in situ hybridization with colorimetric detection, with good concordance of the data. Chemiluminescence in situ hybridization therefore offers the possibility of detecting HPV DNA with great sensitivity in biopsy specimens. Moreover, the images of the samples, stored in the computer, are a permanent record of the reaction and can also be sent for evaluation or comparison to other laboratories using computer networks.

Abstract
Two hundred and thirty paraffin-embedded biopsies obtained from female cervical lesions were tested for the presence of human papillomavirus (HPV) types 6/11, 16/18 and 31/33/35 DNA using non-isotopic in situ hybridization. Specimens were classified according to the Bethesda System in low grade squamous intraepithelial lesion (LSIL), high grade SIL (HSIL) and squamous cell carcinoma (SCC). HPV prevalence ranged from 92.5% in LSIL to 68.5% in SCC. Benign types were prevalent in LSILs while oncogenic types infected predominantly HSILs and SCC. HPV infection showed to be age-dependent, but no significant relation to race has been detected. Patients were analyzed through a five-year period: 20.7% of the lesions spontaneously regressed while 48.9% persisted and 30.4% progressed to carcinoma. Patients submitted to treatment showed a 19.4% recurrence rate. High risk types were present in 78.6% (CrudeOR 13.8, P = 0.0003) of the progressive lesions, and in 73.7% of the recurrent SILs (COR 19.3, P = 0.0000001). Possible co-factors have also been evaluated: history of other sexually transmitted diseases showed to be positively related either to progression (Adjusted OR 13.0, P = 0.0002) or to recurrence (AOR 17.2, P = 0.0002) while oral contraceptive use and tobacco smoking were not significantly related to them (P > 0.1). Association of two or more co-factors also proved to be related to both progression and recurrence, indicating that they may interact with HPV infection in order to increase the risk of developing malignant lesions.

Abstract
Human papillomaviruses (HPVs) cause benign tumors in the respiratory tract. Mounting evidence suggests that they also play a role in the etiology of a subset of head and neck cancers. Carcinomas in patients with a history of recurrent respiratory papillomatosis clearly are caused by persisting HPV interacting with one of more carcinogenic agents. Verrucous carcinomas of the oral cavity, tonsillar and tongue carcinomas are strongly linked with HPVs, based on molecular epidemiologic data. Tonsillar cancer have been shown to express HPV RNA, presumed necessary to induce and maintain a carcinoma, supporting a viral etiology. This paper reviews the molecular and cellular basis for considering HPVs as causative agents of cancer, and reviews the literature that considers the possible role of HPVs in head and neck cancer.

Abstract
Infection of the uterine cervix with human papillomavirus (HPV) is associated with dysplastic lesions that may progress to malignancy. Certain HPV types are associated with higher risk of cervical cancer than other genital HPVs. The goal of this study was to determine if cells obtained by cervicovaginal lavage contain similar HPV types as paired cervical biopsy in women referred because of abnormal cervical cytology. Thirty-four paired lavage and biopsy samples were analyzed for HPV DNA by hybrid capture, using "low risk" (HPV types 6. 11, and related types and "high risk" group (HPV types 16, 18, and related types) HPV. HPV was detected in 24 lavage samples and 18 biopsies. High risk types were predominant. In 14 of 18 HPV-positive biopsies, the paired lavage was also positive for the same HPV group. Four biopsies were HPV-positive at low levels, and the paired lavage was HPV-negative. The mean viral copy numbers of the biopsies from patients with positive and negative lavage samples were 2.7 and 0.1, respectively (P = .02). Ten low level HPV infections were detected by lavage that were not detected by biopsy. HPV detection by hybrid capture in cells obtained by cervicovaginal lavage reflects the results of HPV testing in cervical biopsies.

Abstract
Screening for high-risk human papillomavirus (HPV) types allows the detection of women at a high risk of cervical squamous carcinomas, thereby defining a subset of patients targeted for more intensive screening and follow-up. Thirty-four cervical biopsy specimens and isolated cells from cervical smears of normal women or women diagnosed with high-grade intraepithelial lesion (HGSIL) were screened for the presence of HPV by in situ hybridization (ISH) and/or by polymerase chain reaction (PCR). The exact HPV type was determined using a novel restriction typing method. The detection of HPV was facilitated greatly by the use of a PCR-enzyme-linked immunosorbent assay (ELISA)-based method. HPV was detected by PCR in 32% of the biopsy specimens, whereas only 23% had a positive staining by ISH. In one case, a double infection was detected by ISH as well as by PCR. In two cases, the presence of HPV was detected by both methods but the exact type was different. Analyzing cells isolated from cervical smears by the PCR-ELISA technique or by PCR followed by agarose gel electrophoresis, HPV was detected only in patients with HGSIL and not in the control group. The PCR system is more sensitive than conventional ISH, and the PCR-ELISA system presented in this study is efficient in screening large series of cytological samples. Furthermore, this system allows exact HPV typing on the microtiter plate. These innovations may allow the application of HPV detection and typing as a routine screening method to identify patients with a high risk of developing cervical neoplasia.

Abstract
HPV is suspected of being a major cause of cancer of the uterine cervix. To understand the risk of disease in the general population of women, it is important to estimate the prevalence of HPV infection in a random population-based sample of women without disease. In this study, a total of 231 randomly selected women without dysplasia (controls) were examined, and compared with 103 women with histologically confirmed CIN II-III (patients). The prevalence of HPV DNA in cervical scrapes was determined by general nested PCR, which was expected to detect any relevant HPV type commonly found in cervical samples. The nested positive samples were typed with type-specific PCR. In the general nested PCR, 15% of the controls were positive, compared to 91% of the patients. In the population-based sample, 2.2% had HPV types 6 and 11 and 10% had types 16, 18, 31, and 33. In both groups, HPV DNA was observed less frequently in women above than below the age of 30. The results are among the few population-based figures on the prevalence of HPV in women, and provide a baseline for understanding the risk of developing cancer of the uterine cervix, and determining the proportion of women to be included in intervention studies.

Abstract
Diverging data exist on human papillomavirus (HPV) prevalence in cytomorphologically normal scrapes during pregnancy. The prevalence of HPV was therefore investigated by polymerase chain reaction method (PCR) in cytomorphologically normal scrapes of 709 pregnant women and 3,948 non-pregnant women visiting the same hospital during the same time period. The prevalence of all types of HPV among pregnant women was 9.6% (68/709) and the high risk HPV types of 16 and 18 were found in 3.1% (22/709). In the non-pregnant women the prevalence of all types of HPV was 10.9% (432/3,948) with 2.9% (116/3,948) HPV types 16 and 18. The highest prevalence of HPV was present in women at younger ages in both groups. With increasing age the prevalence declines from about 19% (15-25 yrs) to 5% (40-49 yrs). The age-adjusted odds ratio of prevalence of all types of HPV in pregnant versus non-pregnant women was 0.73 (95% CI 0.56-0.96, P = 0.025) and statistically significant. When HPV types 16 and 18 were considered, significant differences were not found. HPV of all types and types 16/18 prevalence was higher in the second half of pregnancy than in the first part but did not reach statistical significance. High HPV copy numbers in the scrapes were found during the first half of the pregnancy and not during the second half using a semi-quantitative HPV 16/18 PCR detection method. Since the difference in HPV prevalence between non-pregnant and pregnant women is very small, it is concluded that HPV prevalence in cytomorphologically normal smears is hardly influenced by pregnancy.

Abstract
We investigated the association between human papillomavirus (HPV) infection and p53 gene mutation in 47 primary uterine cervical cancers. HPV DNA sequences were present in 43 cancers (91.5%), and one of these cancers contained a p53 gene mutation. In addition, one of the remaining four HPV-negative cancers also contained a p53 gene mutation. As a result, p53 inactivation corresponded to the development of 44 of the primary uterine cervical cancers studied (93.6%). We obtained both primary and recurrent tumours from four cases. In two of these cases, the HPV genomes that were present in an episomal state in the primary tumours were observed to have disappeared in the recurrent tumours. One of these recurrent tumours also contained a p53 gene mutation, which suggested the possibility that p53 inactivation was required in order to maintain the aggressive behaviour in this cancer either by an HPV infection or by a p53 gene mutation. No MDM2 gene amplification was observed in the tumours that carried neither HPV DNAs nor p53 gene mutations.

Abstract
OBJECTIVES The study evaluated the conflicting results of the role of human papillomavirus (HPV) in the development of bladder carcinoma. METHODS We analyzed the frequency of HPV types 6, 11, 16, 18, and 33 by using polymerase chain reaction on formalin-fixed, paraffin-embedded specimens, from 75 cases of transitional cell carcinoma (TCC) of the bladder. Fifteen samples of normal urothelium adjacent to TCC (10) or from normal bladder obtained at autopsy (5) served as negative controls. RESULTS HPV type 16 deoxyribonucleic acid (DNA) was detected in 2 (2.7%) of the 75 cases of TCC and in none of the normal urinary bladder cases. The 2 patients with HPV type 16 were immunosuppressed after undergoing renal and cardiac transplantation. CONCLUSIONS These results strongly suggest that HPVs play a minor role in the development of TCC of the bladder in the general population, although they can act as oncogenic agents in predisposed patients, such as those who are immunosuppressed.

Abstract
Sixty-eight cervical carcinoma biopsies from women at Groote Schuur hospital in Cape Town were screened for human papillomavirus (HPV) DNA by polymerase chain reaction (PCR) amplification with subsequent typing by hybridisation with specific oligonucleotides. Amplified DNAs which hybridised with the HPV group-specific oligonucleotide probes, but with none of the type-specific probes, were categorized as unclassified HPV types. Eighty-one percent of samples were HPV positive and the following distribution and types were detected: 46% HPV 16, 1.5% HPV 18, 6% HPV 31, 6% HPV 33, 1.5% HPV 45, and 25% unclassified HPVs. Four of the tumours had detectable dual infections with the following combinations of HPVs: HPV31/HPV33; HPV16/HPV33; HPV18/HPV16; HPV45/HPV33. Tumour DNA from the 17 PCR unclassified HPVs was analysed by Southern blotting and gave the following results: 11 were negative, 4 were positive on hybridisation but could not be typed (unclassified HPV), 1 was HPV 16, and 1 resembled the HPV 16 "variant" described previously [Williamson et al. (1989): Journal of Medical Virology 28:146-149]. Only 2 of 13 samples that were negative for HPV by PCR were positive for unclassified HPVs by Southern blot analysis. Sequencing of a PCR product revealed that one of the unclassified HPVs was HPV 52. This is the first record of HPV 52 and HPV 45 in Africa.

Abstract
OBJECTIVE To determine if HPV detection or the size of a tampon specimen is affected by the menstrual cycle. MATERIALS Two hundred and eighty women between 18-35 years of age attending a gynaecology clinic at The Royal Women's Hospital were enrolled. Each woman completed a questionnaire on the risk factors of HPV infection and provided a tampon specimen. Specimens were analysed for the presence of HPV DNA (polymerase chain reaction with the L1 consensus primers) after the pellet volume and number of cells was assessed. RESULTS The mean age of the 298 women enrolled in this study was 27.0 years (SD 4.5, range 18-35). Ninety two (30.9%) of the tampon specimens were positive for HPV using the L1 consensus primer. The detection of HPV DNA was not associated with the quartiles of the menstrual cycle (p = 0.32). Both the pellet volume and the number of cells from a tampon specimen were greater during the mid cycle, although this was significant for the pellet volume only (p = 0.002 and 0.1 respectively). The pellet volume was not significantly associated with other variables assessed by the questionnaire. The number of cells from a tampon specimen increased with the numbers of life time sexual partners (p = 0.02) and was higher for a single marital status (p = 0.0008). CONCLUSION The timing of the menstrual cycle effects the size of tampon specimens but not the probability of detecting HPV DNA.

Abstract
Condyloma acuminatum (CA) has high recurrence rates after local treatments. Why this lesion is difficult to eradicate is unclear. One possible explanation for recurrence after superficial destructive therapy is the presence of residual human papillomavirus (HPV) in the superficial dermis beneath the treated epidermis. Thirteen samples of CA were excised from 13 patients. Thirteen samples of basal cell carcinoma (BCC) were studied for purposes of control. Epidermis was separated from dermis by treatment with sodium bromide. DNA was extracted from both tissues and used sodium bromide solution and amplified for the presence of HPV DNA using the polymerase chain reaction. HPV DNA was detected in the epidermis of 11 samples of CA. HPV type 6 was seen in 7 specimens; HPV type 11, in 4. HPV DNA was found in the dermis of 3 specimens of CA; type 6 in 2 and type 11 in 1. Two samples were excluded because of contamination of the sodium bromide solution by HPV. HPV DNA was not detected in tissue samples from BCC. The presence of HPV DNA in the dermis of some condylomata may explain recurrence in sporadic cases.

Abstract
Exophytic condylomata acuminata of the external genitalia of 40 patients were analyzed for human papillomavirus (HPV) DNA by the Southern blot and hybrid capture methods. All lesions were initially analyzed by the Southern blot method by using a mixture of HPV type 6, 11, 16, and 18 whole genomic probes. Southern blots demonstrated characteristic PstI restriction patterns of HPV type 6, 11, or 16 in all but one lesion. HPV 6 subtypes accounted for 28 of 39 HPV-positive lesions. Twenty-seven of these 28 lesions contained HPV type 6a, and 1 lesion contained HPV type 6c. Eight lesions contained HPV type 11 and three contained HPV type 16. Two of the three condylomata acuminata containing HPV type 16 were obtained from solid-organ transplant recipients receiving immunosuppressive medications. The third lesion containing HPV type 16 was a typical exophytic condyloma acuminatum from a woman with previously resected vulvar carcinoma. The hybrid capture assay detected HPV DNAs in all lesions except the Southern blot-negative lesion. Twenty-five lesions were positive for the A probe only (HPV types 6 and 11 and related types). All of these lesions were found to contain HPV type 6 or 11 sequences in the Southern blot assay. The remaining 14 lesions were positive for both the A probe and the B probe (HPV types 16 and 18 and related types). The strongest signal in these 14 lesions by the hybrid capture assay was consistent with the result of the Southern blot assay in all but one case. We conclude that (i) HPV type 6a is the most common type found in these lesions, (ii) HPV type 16 may be present more often in exophytic condylomata acuminata from immunosuppressed individuals, (iii) hybrid capture is a useful tool for documenting the presence of HPV sequences in DNAs from exophytic condylomata acuminata, and (iv) in samples containing multiple HPV types, hybrid capture allows detection of minority HPV types.

Abstract
OBJECTIVE To assess the diagnostic criteria of genital HPV lesions in male sexual partners of HPV infected women. METHODS Peniscopically directed biopsy specimens (from 693 lesions in 300 men) were examined on light microscopy and in situ hybridisation (ISH) for HPV types 6,11,16,18,31,33 and 42. The predictive value of different histological criteria for ISH positivity was also evaluated using stepwise logistic regression analysis. RESULTS Flat HPV lesions were most accurately predicted by the punctuation pattern on peniscopy, giving the concordance between peniscopy and histology between peniscopy and histology of 79.5% (66/83) and that between peniscopy and ISH of 56.6% (47/83). Diffuse acetowhite pattern disclosed a typical HPV lesion in only 17.8% (13/73), and HPV DNA was found in 11.0% (8/73) of cases. Of the 114 biopsy specimens from peniscopically healthy areas adjacent (0.5-1 cm) to the lesions, 93.0% (106/114) were normal on light microscopy, and HPV DNA was found in only 2.6%. Penile intraepithelial neoplasia (PIN) lesions were most frequently ISH positive, 81.1% (30/37), 50% showing HPV 16 and/or 18 DNA. Lesions classified as HPV-suspicious or nonspecific on light microscopy were HPV DNA-positive in 16.9% (11/65) and 8.1% (13/160), the frequency of high-risk HPV types being 3.1% and 1.3%, respectively. In logistic regression analysis, koilocytosis was the most powerful predictor of ISH-positivity in the flat lesions (without PIN), the risk ratio being 3.7. CONCLUSION No conclusive peniscopic criteria for male HPV infections could be established, making histological evaluation mandatory. Care should be exercised in interpreting as HPV lesions the cases devoid of koilocytosis, HPV typing being essential in confirming the diagnosis in doubtful cases.

Abstract
The aim of this study was to compare the sensitivity of Southern blot (SB) and dot blot (DB) hybridisation with polymerase chain reaction (PCR) for the detection of HPV in cervical biopsies from samples with differing histology. One hundred and forty seven women with cervical dysplasia had biopsies performed; one sample was analyzed for HPV DNA from types 6/11, 16, and 18 by SB, DB and PCR (L1 consensus primer and type specific probes) while an adjacent sample was examined histologically. The histology of the samples was normal in 40 (27%), squamous metaplasia in 25 (17%), inflammation 2 (1%) HPV infection 24 (17%), cervical intraepithelial neoplasia (CIN) grade I in 11 (7%), CIN II in 18 (12%), CIN III in 22 (15%), while 5 (3%) had invasive cancer. The number of biopsies positive for HPV DNA from types 6/11, 16, and 18, using the different hybridisation methods was 56 (38%) by dot blot, 57 (39%) by Southern blot hybridisation and 66 (45%) by PCR. When the L1 consensus primer was used 100 (68%) specimens were positive by PCR. The sensitivity of SB and DB hybridisation, as compared with PCR (type specific probes 6/11, 16, 18) was greater in biopsies with abnormal histology (histological grades of HPV infection and greater, as a group) (sensitivity of SB 83%, DB 74%) than those with normal and metaplastic change (as a group) (sensitivity of SB 44%, DB 35%) (P < 0.005 for SB and DB) (inflammation excluded from analysis). This study demonstrated that the sensitivity of SB and DB hybridisation, relative to PCR is greater in samples with abnormal histology than in samples with normal histology.

Abstract
A total of 377 women, consecutively selected as first attenders to a sexually transmitted diseases clinic in Melbourne, Australia, were examined for overt Condylomata acuminata and were screened for genital HPV DNA types 6, 11, 16, 18, 31, 33 and (35) using 2 dot blot hybridization methods. Overall, there was a 90% positivity correlation between the 2 methods with HPV DNA being detected in 12% of ectocervical samples. Overt warts were found in 15% of the women and HPV DNA was detected at the cervix in 35% with cytology predicting HPV with or without dysplasia in 27%. Thirteen percent had a past history of warts but none on examination and HPV DNA was evident in 16% while 18% had cytological features of HPV. Those with no warts evident and no past history of warts had both HPV DNA and cytological features of HPV in 7%.

Abstract
Human papillomavirus (HPV) types 16 and 18 in 66 women with histologically documented lesions of the genital tract and 64 control cohorts were investigated. The efficacies of in situ hybridization and polymerase chain reaction (PCR) in detecting HPV 16 and 18 DNA were analyzed. In order to assess the usefulness of replacing biopsies with cervical scrapes, the two samples were compared by PCR. The prevalence rates of HPV infection by PCR were 59.1 and 10.9% in patients and controls, respectively. PCR was three times more sensitive than in situ hybridization (52.6 versus 17.8%). However, the need to improve PCR sensitivity by subsequent dot blot hybridization reduced one of the main advantages of PCR, i.e., expeditious diagnosis. Cervical scrapes were less sensitive than biopsies (13.6 versus 53%), although with four (6.1%) patients with intraepithelial neoplasias, HPV DNA was identified only by means of cervical scraping. We conclude that obtaining biopsy specimens and cervical scraping are complementary sampling procedures.

Abstract
Type-specific 30'mer-36'mer oligonucleotide probes complementary to mRNA transcribed from the E6 and E7 open reading frames of HPV 6b/11, 16, 18 and 33 were designed using the published nucleotide sequences. As oligonucleotides are easily and relatively cheaply synthesized in large amounts and are free of vector DNA, they were assessed for potential use in routine clinical detection and typing of HPV. Multiple Southern and dot blots of cloned HPV 6b, 11, 16, 18, 31 and 33 DNA, and of DNA extracted from cell lines carrying integrated HPV 16 and 18 genomes were prepared. In addition, Northern and dot blots of RNA extracted from the HPV-containing cell lines HeLa, CaSki and SiHa, were also prepared. All filters were first probed with the oligonucleotide and then with the corresponding full-genomic HPV DNA probe and their relative sensitivities and specificities compared: both probe types were labelled with 32P. The oligonucleotide probes were all as specific as the full-genomic probes for Southern, DNA and RNA dot blot hybridisations. The HPV 16 and 18 oligonucleotide probes detected HPV transcripts of the appropriate sizes in the cell line RNA. For DNA detection, oligonucleotide probes were up to 10 times less sensitive than the full-genomic probes, but for RNA detection, they were more sensitive. The sensitivity for both HPV DNA and RNA detection could be improved by using two type-specific oligonucleotide probes in combination, without reducing the specificity. The ease of preparation and handling of oligonucleotide probes, together with their lack of contaminating vector DNA, suggests that they may have some advantages over full-genomic probes for the clinical detection and typing of HPV.

Abstract
BACKGROUND AND METHODS We have carried out a prospective study of dual genitotropic human papillomavirus (HPV) infections by means of two different DNA detection methods in biopsy specimens obtained from patients who were examined for genital warts at the STD clinic of the School of Medicine in Seville, between January 1990 and December 1991. RESULTS 100 patients with a clinical diagnosis of condilomata acuminata were seen during the study period. DNA of the genitotropic HPV 6/11, 16/18 and 31/33/35 was detected by an in situ hybridisation method in 75 (77%) of the 98 evaluable samples; one of the genotypes tested in 59 (61%) samples, and two or more genotypes tested in the remaining 16 (15%) samples. In 21 (98%) of the 23 negative samples by in situ hybridisation, we were able to detect DNA of genital HPV using a polymerase chain reaction amplification method (PCR). Among the 34 samples where PCR was applied we confirmed the presence of two different HPV genotypes in eight samples. CONCLUSIONS The frequency of dual infections with human genitotropic papillomavirus in genital warts was 8%, although we believe that this rate should be higher as we have not used the PCR method in all of the samples.

Abstract
The polymerase chain reaction (PCR) for the diagnosis of human papillomavirus (HPV) infections, and in particular for the study of cervical HPV-associated lesions, is used widely. We identified a novel set of universal primers that are able to amplify a fragment spanning the E1 open reading frame (ORF) from different mucosotropic HPV types. A restriction endonuclease digestion of the amplified products is suggested for accurate typing. In particular, AluI digestion of the amplified fragments yields a distinctive fragment pattern for each 'high-risk' (16, 18, 31 and 33) HPV sequence, thus distinguishing them from 'low-risk' (6b and 11) HPV sequences.

Abstract
By means of a consensus polymerase chain reaction (PCR) method, the prevalence of HPV types was determined in cervical biopsies from 137 women referred to the gynecological outpatient clinic for colposcopy because of an abnormal cervical smear. The prevalence of HPV was 80.3%. There was a statistically highly significant rise in the prevalence of the oncogenic HPV types (16, 18, 31, 33) with increasing severity of cervical intraepithelial neoplasia (CIN I to III), indicating a role for these HPV types in the pathogenesis of cervical cancer. The prevalence of other HPV types decreased significantly with the severity of the lesion, suggesting that these HPV types play a less significant role in this process. These data indicate that HPV typing with PCR may be a valuable tool for distinguishing between high-risk and low-risk cervical lesions. Furthermore, our results suggest that the detection of HPV types by consensus PCR in the cervix of patients with an abnormal smear but without histologically detectable CIN is a useful tool for predicting which of these patients will eventually develop CIN. Finally, a relatively low percentage (3%) of HPV double infections is reported in this study.

Abstract
The human papillomavirus (HPV) is the most common organism to infect the human genital tract, affecting as much as half, or more, of the sexually active population. This virus has become widely recognized through the well publicized relationship with genital tract neoplasia and through new diagnostic technologies, such as monoclonal antibody analysis, DNA hybridization, and the polymerase chain reaction. This paper describes the full spectrum of HPV infections, starting with pathogenesis and continuing to clinical manifestations, and discusses significance, diagnosis, and management.

Abstract
A case-control study compared detection by polymerase chain reaction (PCR) specific for human papillomavirus (HPV) type 16 with restriction enzyme analysis and Southern blot hybridization detection of HPV type 16. Cervicovaginal lavage samples from 64 women with histopathologic evidence of a cervical squamous intraepithelial lesion and 55 samples from cytologically healthy women were studied. Several methods of PCR product analysis, including radioactive and nonradioactive probing, were compared. The sensitivity of HPV detection by PCR when the amplified DNA fragment was visualized on a gel was equivalent to those of detection by restriction enzyme and Southern blot analyses. Hybridization of the PCR product with radioactively or nonradioactively labeled oligonucleotide probes increased the sensitivity of HPV detection by 100-fold. However, an increase in the sensitivity of the assay preferentially identified low levels of the virus in cytologically healthy women. Therefore, the value of HPV detection in identifying women with cervical neoplastic disease was greater, and the odds ratio for the presence of a cervical squamous intraepithelial lesion was higher when the less sensitive modalities were used. These results suggest that quantitation of HPV by PCR may maximize the clinical significance of a positive test result. Further studies will be needed to determine the optimal level of virus detection which has the highest positive predictive value of clinical disease.

Abstract
Tumor biopsies from exophytic and flat condylomas at different locations on the genital epithelium (10 cases) and in cervical intraepithelial neoplasia (CIN) grades 1-2 (6 cases) were analysed for HPV types 6 and 11 DNA and RNA. The presence of mRNA species which could encode the E6, E7, E1M, E2, E2C, E4, E5 and L1 proteins was determined using the RNA polymerase chain reaction (PCR) technique with primers that flank previously mapped or predicted splice sites. The state of the viral DNA in the tumor biopsies was established by Southern blot analysis. We could detect the various mRNA species in biopsies from condylomas associated with both HPV types. The size of the RNA PCR products were in agreement with the previously mapped splice sites of mRNAs recovered from an experimental condyloma induced by HPV11. The major viral transcript encoding the E1i--E4 protein was detected in all the tumor biopsies. From the rare transcripts the rate of detection of mRNA species encoding the E1M, E2C proteins was the highest. In 2 of 6 CIN biopsies analysed only the major viral transcript was detected. The overall results of this study suggest that early gene products of HPV types 6 and 11 may be important in the induction of cellular proliferation and condylamatous differentiation but these possibly may not be required for the development of the HPV-associated cervical neoplasia.

Abstract
Both experimental and epidemiological data support the idea that oral contraceptive (OC) use may have a stimulating effect to a certain point on cervical carcinogenesis. The current investigation tries to answer the question whether OC use might have an influence on early human papillomavirus (HPV) infections. A total of 425 women without abnormal cytological results were examined colposcopically, and filter in situ hybridisation (FISH) was used to determine the presence of human papillomavirus (HPV) types 6, 11, 16 and 18. Eighty-one cervical specimens (19.1%) were found to be positive for one or more of the HPV types in FISH. HPV positivity was found to correlate with age and parity, being the highest among women under 25 and with less than two births. The use of OCs was inversely correlated with the presence of ectopy or dysplasia in this group of women. On the other hand, HPV positivity was not significantly higher among OC users than among non-users in any colposcopic group. Neither the type of pill used, nor the duration of use had any significant effect on HPV positivity. Further investigations are needed to evaluate the effects of OC use on more severe HPV-induced cervical lesions.

Abstract
We performed a second examination for human papillomavirus (HPV) DNA on 51 sexually experienced 13- to 21-year-old (mean = 17.8 years) female patients seen at an urban teaching hospital. Cervicovaginal lavages were performed 6 to 36 months apart (median = 13.3 months) to collect cells for HPV DNA detection and typing by Southern blot hybridization. At the first and second visits, 39.2% (20/51) and 25.5% (13/51) of patients, respectively, were infected with HPV. Collectively, 56.9% (29/51) of patients had at least one positive HPV test result. Although 7.8% (4/51) were infected with HPV at both visits, only one patient had infection with the same HPV type. These findings suggest that although HPV infection is a common sexually transmitted disease, genotype-specific HPV infection detected by Southern blot at two visits was rare.

Abstract
Cervical smears from 1,178 women with cytologically normal cervices and 67 women with cervical intra-epithelial neoplasia (CIN) or cervical carcinoma were analyzed for the presence of HPV 6, 11, 16 and 18 DNA by slot-blot hybridization. HPV DNA was detected in 17% (95% CI: 14%-19%) of the women with a normal smear; 11% of infected women harboured HPV 16 and 18 (95% CI: 9%-13%, each). HPV DNA was detected in 54% (95% CI: 41%-66%) of patients with abnormal smear; the most prevalent virus type in this group was HPV 16 (45%; 95% CI: 32%-38%). In order to verify the slot-blot results, a proportion of the samples was also investigated by PCR. There was 88% correlation between the 2 tests. The high prevalence of HPV 16 and 18 infection demonstrated in our low-cervical-cancer-risk area further support the role of as yet unidentified co-factors as determinants of the different geographic rates of cervical-cancer incidence.

Abstract
Because genital human papillomavirus (HPV) infections tend to be multifocal, it was studied how effective one combined specimen is in detecting HPV-DNA from the lower female genital tract. The study population consisted of 50 patients referred to a colposcopy clinic for a suspected condylomatous and/or dysplastic lesion. From half of the patients, a separate scrape from the cervix, vagina and vulva was taken first followed by a combined scrape representing all the genital sites, and from the other half, vice versa. HPV-DNA (types 6, 11, 16 and 18) was identified using the AffiProbe hybridisation test. Thirty-six specimens collected from 17 patients were positive for HPV-DNA. A multifocal infection was demonstrated in at least 11/17 (65%) HPV-DNA positive patients. The combined scrape was the most informative specimen, revealing 75% of all HPV-DNA-positive patients. It was concluded that HPV-DNA can reliably be detected from the female genital tract in a simple way from one combined specimen.

Abstract
OBJECTIVE To review the role of human papillomavirus (HPV) as a causative agent of cancer of the cervix. DATA SOURCES, data synthesis, study selection: Medical journals, recently published text books related to cancer of the cervix and HPV and Papillomavirus Reports were examined to review the pathology of cervical cancer and its precursor lesions, its epidemiology in Australia and overseas, methods of detection of HPV (in particular molecular biology techniques used to diagnose HPV) and evidence linking HPV with genital neoplasia. CONCLUSION While there is compelling evidence strongly linking certain HPV types with genital cancer, a causative role is yet to be proven and the aetiology is most likely multifactorial. Detection and typing of high risk genotypes of HPV in the genital tract as a diagnostic exercise to identify those women most at risk of developing genital neoplasia is not currently recommended.

Abstract
The presence of human papillomavirus (HPV) types 2, 6, 7, 11, 13 and 16 DNA in cytologic scrapings of oral mucosa was studied in 309 women with genital HPV infections. The objective was to test the usefulness of oral mucosal scrapings (3 sequential swabs) in HPV DNA detection by dot blot hybridization. Based on hybridization with the 32P-labelled Alu-repeat probe, most samples contained more than 10(5) cells, which is an adequate number of cells for dot blot hybridization. Hybridization with 32P-labelled HPV DNA probes showed that 3.8% of the 309 women had an oral HPV infection. Of these, only 2 had clinical lesions indicative of HPV. All other oral HPV positive subjects had clinically healthy mucosa. HPV 6 was the most common (3.1%) type, followed by HPV 11 and 16 (1.1%). In 3 cases the genital mucosa harboured the same HPV type as found in the oral cavity. The results indicate that oral mucosal scraping results in adequate number of cells for dot blot hybridization with HPV DNA. Although the method is likely to result in an underestimation of latent and subclinical HPV infections, it is useful for studying the clinical HPV infections as well as other viral infections known to be present in exfoliated cells.

Abstract
We have used a polymerase chain reaction (PCR) to examine cervical cancer biopsy specimens and pelvic lymph nodes for the presence of human papillomavirus type 16 (HPV 16) DNA. Of the 75 cervical specimens tested, 36 (48%) were positive for HPV 16 in the PCR. A total of 65 pelvic lymph nodes removed during radical surgery on 35 women were also analyzed. Lymph nodes originating from 19 patients whose cervical biopsy specimens were negative for HPV 16 seemed to lack HPV 16 sequences. For 16 women with positive PCR results for cervical biopsy specimens, 9 of 10 lymph node metastases were positive in the PCR, while 11 of their 36 histologically negative lymph nodes were also shown to contain HPV 16 DNA.
