Abstract
Human papillomavirus (HPV) is implicated in over 90% of cervical cancer cases, with factors like regional variability, HPV genotype, the population studied, HPV vaccination status, and anatomical sample collection location influencing the prevalence and pathology of HPV-induced cancer. HPV-16 and -18 are mainly responsible for the progression of several cancers, including cervix, anus, vagina, penis, vulva, and oropharynx. The oncogenic ability of HPV is not only sufficient for the progression of malignancy, but also for other tumor-generating steps required for the production of invasive cancer, such as coinfection with other viruses, lifestyle factors such as high parity, smoking, tobacco chewing, use of contraceptives for a long time, and immune responses such as stimulation of chronic stromal inflammation and immune deviation in the tumor microenvironment. Viral evasion from immunosurveillance also supports viral persistence, and virus-like particle-based prophylactic vaccines have been licensed, which are effective against high-risk HPV types. In addition, vaccination awareness programs and preventive strategies could help reduce the rate and incidence of HPV infection. In this review, we emphasize HPV infection and its role in cancer progression, molecular and immunopathogenesis, host immune response, immune evasion by HPV, vaccination, and preventive schemes battling HPV infection and HPV-related cancers.

Inequities in Screening and HPV Vaccination Programs and Their Impact on Cervical Cancer Statistics in Romania. Diagnostics (Basel) 2023; 13:2776. [PMID: 37685314 PMCID: PMC10486539 DOI: 10.3390/diagnostics13172776] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/23/2023] [Accepted: 08/24/2023] [Indexed: 09/10/2023] Open
Abstract
(1) Introduction: A Romanian woman is diagnosed with cervical cancer every two hours; the country ranks second in Europe in terms of the mortality and incidence rate of this disease. This paper aims to identify the main reasons that have led to this situation, focusing on the measures taken by the Romanian Ministry of Health for the prevention of this type of cancer-national programs for cervical cancer screening and HPV vaccination. (2) Materials and methods: We performed a study based on the available secondary data from the National Statistics Institute, World Health Organization and Bucharest Institute of Oncology in order to assess the burden associated with cervical cancer and place it in the context of known global and European incidence and mortality rates, thus evaluating the importance of this health issue in Romania. The second component of our study was a cross-sectional study. Here, we used a 14-question questionnaire applied to the women participating in the National Screening Program for Cervical Cancer and aimed to evaluate the women's level of knowledge about screening and HPV vaccination and their access cervical-cancer-specific healthcare services. (3) Results: The results of this research show that a high percentage of women postpone routine checks due to a lack of time and financial resources and indicate that a low level of knowledge about the disease and the specific preventive methods determines the low participation in screening and HPV vaccination programs implemented in Romania, contributing to the country's cervical cancer situation. (4) Conclusions: The national programs have complicated procedures, are underfunded and do not motivate healthcare workers enough. This, combined with the lack of information for the eligible population, adds up to an extremely low number of women screened and vaccinated. Our conclusion is that the Romanian Ministry of Health must take immediate action by conducting major awareness campaigns, implementing measures to make the programs functional and ensuring coherent funding.

Abstract
High-risk human papillomavirus (HPV) infection is the most common cause of cervical cancer, but low-risk HPV strains can sometimes also be involved. Although HPV genotyping techniques used in clinical diagnosis cannot detect low-risk HPV, next-generation sequencing (NGS) can detect both types. However, DNA library preparation is complicated and expensive. The aim of this study was to develop a simplified, cost-effective sample preparation procedure for HPV genotyping based on next-generation sequencing (NGS). After DNA extraction, a first round of PCR was performed using modified MY09/11 primers specific for the L1 region of the HPV genome, followed by a second round of PCR to add the indexes and adaptors. Then, the DNA libraries were purified and quantified, and high-throughput sequencing was performed using an Illumina MiSeq platform. The sequencing reads were compared with reference sequences for HPV genotyping. The limit of detection for HPV amplification was 100 copies/µl. Analysis of the correlation of pathological cytology with the HPV genotype in individual clinical samples showed that HPV66 was the most common genotype found in the normal stage, whereas HPV16 was the main genotype found in low-grade squamous intraepithelial lesions, high-grade squamous intraepithelial lesions, and cervical cancer. This NGS method can detect and identify several HPV genotypes with 92% accuracy and 100% reproducibility, and it shows potential as a simplified and cost-effective technique for large-scale HPV genotyping in clinical samples.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted agent worldwide. Early prevention with HPV vaccination is a safe and effective method against this disease. HPV vaccines provided more protection against several oncogenic HPV strains. Three prophylactic HPV vaccines have been approved to target high-risk HPV types and protect against HPV-related disorders. These existing vaccines are based on the recombinant DNA technology and purified L1 protein that is assembled to form HPV empty shells. The prophylactic vaccines are highly immunogenic and can induce production of specific neutralizing antibodies. However, therapeutic vaccines are different from these prophylactic vaccines. They induced cell-mediated immunity against transformed cells, instead of neutralizing antibodies. The second generation of prophylactic HPV vaccines, made from alternative viral components using cost-effective production strategies, is undergoing clinical evaluation. The purpose of this review is to provide a complete and up-to-date review of the types of HPV vaccines and the efficiency of each of them for readers.

Distribution of human papillomavirus in precancerous and cancerous cervical neoplasia in Tunisian women. Infect Agent Cancer 2021; 16:52. [PMID: 34271960 PMCID: PMC8283945 DOI: 10.1186/s13027-021-00392-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 06/24/2021] [Indexed: 12/02/2022] Open
Abstract
Background High-risk human papillomavirus (HR-HPV) are responsible for cervical cancer (CC) which represents the second most prevalent gynecological cancer among Tunisian women. Preventive strategies against CC are based on prophylactic vaccines that have not yet been implemented into the national vaccination program of Tunisia. Therefore, the present study aimed to investigate the HPV genotypes distribution in cervical neoplasia in Tunisian women in order to predict the impact of using current HPV vaccines on cancer prevention in Tunisia. Methods A total of 200 formalin-fixed paraffin embedded biopsies were collected in our study. DNA was extracted using Qiagen Mini prep kit. DNA quality was controlled by Beta Globin PCR. Only positive samples for Beta Globin test were used. HPV detection was performed by a nested PCR using PYGMY and GP5+/6+ primers. Genotyping was performed by Reverse Line hybridization using 31 probes. Results The mean age of participants was 38.97 years and 75% were over 30 years. Cervical neoplasia distribution according to age showed that CINII/CINIII was observed among women over 30 years old. All samples were positive for Beta Globin PCR. Overall HPV prevalence in cervical lesions was 83% (166/200). HPV was present in 65% of CINI, 82% of CINII/CINIII and 85% of CC. HR-HPV was statistically significantly associated with cervical intraepithelial neoplasia (p < 10–3). HR-HPV distribution according to lesion grade and cervical cancer showed that HPV16 and HPV18 were present in all lesions. For CINII/CINIII, HPV 35 (37.5%) was the most detected type, followed by HPV18 (33.3%) HPV 45 (28.5%) and HPV 16 (18.9%). HPV 45(57.5%), HPV 18 (53.3%) were the most detected in CC. HPV58, 59, 68 were only detected in CC and associated with HPV45, 18 and HPV16. HPV39, 31, 33, 52, 56 and HPV70 was associated only with CINI. Conclusions Our findings can give useful information for vaccine implementation by helping the health policymakers to choose the most appropriate vaccine type in Tunisia.

Abstract
Objectives: The aim of this study is the documentation of human papilloma virus (HPV) frequency and types seen in the city of Istanbul, Turkey, as well as evaluation of the relationship between these subtypes and cytological and pathological diagnoses. Methods: 4879 cases were studied in our molecular pathology department between 2001 and 2019 in Istanbul. Between 2001 and 2010, 1692 cases were screened for HPV 6, 11, 16, 18, 31, and 33 by conventional hybridization and polymerase chain reaction (PCR). Since 2011, up to 49 HPV typing has been performed for 3187 cases with chip array. The cases were referred to the pathology center and the hospital pathology department by clinicians for screening before HPV vaccination and on the observation of precancerous changes and koilocyts in cytological-histopathological evaluations. Results: In this study, the frequency of HPV was found to be 10.8% (527 HPV-positive cases). Among these, 348 cases were high-risk groups, whether or not they were previously associated with a low-risk group. When we look at the distribution of the cases according to the high-risk HPV types, HPV 16 is the most common type. The frequencies of occurrence of other HPV types are as following: HPV–16: 41.7%, HPV–31: 11.7%, HPV–52: 7.9%, HPV–51: 7.1%, HPV–33: 6.9%, HPV–45: 6.5%, HPV–18: 6.3%, HPV–39: 6.1%, and HPV–58: 5.8%. It was further found that multiple infections were 28% of high grade squamous intraepithelial lesion cases. HPV frequency was 38% and 72%, respectively, in cases with cytologically or histopathological precancerous, low-grade squamous intraepithelial lesion, and HSIL changes. As a final note, HPV was detected in 9 of 10 cases with cervical cancer (90%). Only 1 adenocarcinoma case detected in the series was a double infection with HPV types 18 and 45. Conclusion: HPV 16 was the most common type found in this study. It is followed by types 31, 52, 51, 33, 45, 18, 39, and 58, respectively. The most common association observed in double infections was between HPV 16 and 58. It was also observed that the incidence of HPV in the city of Istanbul, Turkey, was similar to other developed countries. As a final note, in addition to screening tests, PCR and chip array studies should be conducted and the community should be informed about preventive medicine and the importance of condom use.

Abstract
BACKGROUND Cervical cancer is the fourth cancer worldwide. The Human Papilloma Virus is responsible for 99% of the cases but the distribution of its genotypes varies among populations. We aimed to identify HPV genotypes distribution in women with grade 2/3 cervical intraepithelial dysplasia or invasive cervical cancer in Guadeloupe, a French Caribbean territory with a population mainly of African descent. METHODS We used paraffin-embedded tumors for viral DNA extraction from women diagnosed between 2014 and 2016 and identified by the population-based cancer registry. The HPV Genotyping was performed with the InnoLIPA HPV Genotyping Extra kit®. RESULTS Overall, 213 samples out of the 321 eligible records were analyzed. The HPV status was positive for 94% of the cases. The five most common oncogenic HPV genotypes were HPV31 (47%), HPV33 (38%), HPV16 (32%), HPV44 (31%) and HPV26 (28%). HPV18 was found in only in 5% of the cases. Among the studied cases, 94% had multiple infections. More than 60% of single infections were HPV16-related, accounting for 35% of HPV16 infections. CONCLUSIONS These results show a different distribution of oncogenic HPVs in Guadeloupe with "31 > 33 > 16" and a high frequency of multiple infections. Despite a lower coverage, the nine-valent vaccine is nevertheless adequate.

Abstract
Objective To investigate the correlation between hTREC and human papillomavirus (HPV) load and cervical intraepithelial neoplasia (CIN) grade II/III lesions and cervical cancer. Methods A total of 135 patients with cervical lesions of different degrees admitted to our hospital from January 2016 to February 2017 were selected, including CIN I/III 65 cases, grade III 39 cases, and cervical cancer 31 cases. The expression of hTERC gene was detected by fluorescence in situ hybridization (FISH) in three groups, and the HPV load was detected by second‐generation hybridization capture (HC II) method, and its relationship with cervical lesion grade was analyzed. Department. Results The positive expression rate of hTERC gene amplification was cervical cancer > CIN I/II lesion > CIN III lesion; the positive expression rate of HPV was cervical cancer > CIN I/II lesion > CIN III lesion. After treatment, the positive rate of hTERC gene amplification and HPV expression decreased significantly within 1 year (P < .05). Spearman's analysis showed that the degree of cervical lesion was positively correlated with hTREC and HPV load (P < .05). Conclusion hTREC and HPV are closely related to the occurrence and development of cervical precancerous lesions and cervical cancer. The abnormal amplification of hTERC gene increases with the grade of cervical lesions. Both of them can be used as auxiliary indicators for early screening, treatment, and prognosis of cervical cancer.

Abstract
BACKGROUND Human papillomavirus (HPV) is one of the most common sexually transmitted viruses. Data about HPV infection in Guizhou is limited. METHODS 56,768 cervical samples were collected and genotyped for 15 main high risk and 6 main low risk HPV types. RESULTS 16.95% (9623/56768) of samples were HPV positive; 90.70% (8728/9623) of HPV positive women were infected by high risk HPV. High risk and high risk mix infection (1458; 70.85%) was the most common mix HPV infection type. The highest HPV detection rate was found in age group 41-45 years old (detection rate = 17.89%) (χ2 = 204.77; P < 0.001); the highest within-group HPV infection rates were found in the ≤20 (25.62%) and ≥ 61 (24.67%) years old age groups, the lowest within-group HPV infection rate was found in the 31-35 years old age group (15.02%). The highest mix infection proportions were found in the ≥61 (36.06%) and ≤ 20 (33.63%) years old age groups (χ2 = 111.21; P < 0.001), the lowest mix infection proportion was found in the 41-45 (17.42%) years old age group. The highest high risk infection proportions were found in the 26-30 (92.98%), ≥61 (92.68%), and 36-40 (92.16%) years old age groups (χ2 = 31.72; P < 0.001), the lowest high risk infection proportion was found in the ≤20 (84.96%) years old age group. HPV infection rates varied with seasons in Guizhou. CONCLUSIONS Characteristics of HPV distribution in Guizhou were identified. There were significant differences in HPV distribution among age groups, prevention strategies should be adjusted according to the characteristics.

Abstract
Background Identification of 14 high-risk human papillomavirus (HR-HPV) is immensely important in elucidating molecular epidemiology, patient monitoring and evidence-based treatment. There is paucity of such data from Chhattisgarh state of Central India. The present study has evaluated tagging oligonucleotide cleavage and extension-mediated Anyplex HR-HPV genotyping assay in identification of 14 HR-HPV genotypes attributable to premalignant and malignant cervical lesion in comparison to GP5+/6+ assay, cytology and colposcopy. Materials and Methods A total of 185 clinically suspected cases of premalignant and malignant cervical lesion were investigated by HR-HPV genotyping, GP5+/6+, cytology and colposcopy. Results Genotyping assay showed clinical sensitivity and specificity of 86.5% (confidence interval [CI]: 80.7-91.0) and 100% (CI: 86.3-100) respectively and found noninferior to GP5+/6+ assay (P > 0.05). HR-HPV prevalence was 76.3%, 88.4%, 94.8%, 100% and 100% among cervical intraepithelial neoplasia (CIN) Grade I-III, squamous cell carcinoma and adenocarcinoma cases, respectively. The four most common genotypes detected in CIN I-III were HPV 16 (63.9%), HPV 39 (15.0%), HPV 18 (6.0%) and HPV 33 (5.3%). In cervical cancer (CC) cases, HPV 16 (44.4%), HPV 39 (11.1%), dual infection of HPV 16, 18 (11.1%) and triple infection of HPV 16, 18, 33 (11.1%) were the four most identified genotypic aetiologies. A novel coinfection of HR-HPV 35, 39 were found in two and one cases of CIN I and II. Finding of HPV 39 as the second most prevalent genotype was unusual and underscores the importance of genotyping screening. Conclusion Anyplex HR-HPV assay is arguably the useful assay for better patient management and can be useful for HR-HPV screening by its unique individual genotype identification of all HR-HPV. Finding of HPV 16, 39, 18, 33 and coinfection of 16,18 and 16, 18, 33 in CIN and CC would help vaccine manufacturer to design specific future HPV polyvalent vaccine preparation to curb down the CC-associated mortality.

Prevalence of human papillomavirus and subtype distribution in male partners of women with cervical intraepithelial neoplasia (CIN): a systematic review. BMC Infect Dis 2019; 19:192. [PMID: 30808285 PMCID: PMC6390310 DOI: 10.1186/s12879-019-3805-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Accepted: 02/11/2019] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Human Papillomavirus (HPV) infection is estimated to be the most common sexually transmitted infection. The present systematic review summarizes data regarding the prevalence of HPV and the distribution of subtypes in heterosexual male partners of women, who were diagnosed with any grade of cervical intraepithelial neoplasia (CIN). METHODS We conducted a systematic review of the literature by Medline and Google Scholar databases using the terms "Human Papillomavirus" or "HPV" plus "men" or "male partners" or "women with CIN". We included original published English-language articles published from 1/1/2000 until 1/1/2018 that had screened male partners of women with CIN using HPV DNA testing. We excluded studies that they overlapped with other included studies or were unrelated to the study subject. RESULTS We included a total of 12 publications, which reported the prevalence of HPV in free-clinical signs male partners of women with CIN. The largest proportion of the studies were from South America (seven studies), and the rest from Europe. The mean age of participants was 35.18 + - 3.47 years. HPV prevalence ranged from 12.9 to 86%; the total HPV prevalence among the studies was 49.1%, while ten out twelve studies (83.3%) demonstrated prevalence > 20%. Between the studies, the distribution of HPV subtypes varied on the basis of the method used, on the population and on the geographic region. A great variety of subtypes were detected, including 6, 11, 16, 18, 31, 33, 40, 42, 45, 51, 52, 53, 54, 56, 57, 58, 59, 61, 62, 66, 68, 81 and 83. In six studies the HPV 16 was the most frequent, while in two others the HPV 6 and HPV 83. CONCLUSIONS Until now, there are not precise screening or surveillance guidelines for the management of partners of women with CIN. This population is frequently colonized by various HPV subtypes and therefore need to be screened in an effort to reduce the infection in both sexes. The screening test could include detection/identification of HPV subtypes by a molecular assay, followed by peniscopy only in the positive cases.

Abstract
Background Human papillomavirus (HPV) is associated with an increased risk of cervical cancer. Using a vaccine to prevent HPV infections could be a cost-effective strategy to decrease the incidence of cervical cancer. Learning about the characteristics of CIN patients with HPV infection in Wenzhou is a key step in guiding the use of HPV vaccines and screening for cervical cancer. Methods We undertook a retrospective analysis including 2612 women who were treated in the Department of Gynecology and Obstetrics from Jan 2016 to Nov 2017. All of the patients were examined by HPV testing and histology. Results The prevalence of HR-HPV among women with cervical intraepithelial lesions aged 65-69 years (38.8%) was significantly higher than that of the other age groups. The percentage of patients diagnosed with HPV-positive HSIL progressively increased with age to a maximum of 18.0% in the group of 40 to 44 years of age. HPV 16, 52, and 58 were the three most dominant genotypes among these women, and single infections (950, 73.3%) were more common than multiple infections (346, 26.7%). Compared to cervicitis, the odds ratios (ORs) for LSIL associated with HPV 33, 52, 16 and HPV 58 infection were 5.98, 3.91, 3.65, 3.65, and 3.188, respectively; for HSIL associated with HPV 16, 33, 58 and HPV 31 were 9.30, 7.68, 5.97, and 4.21, respectively. In LSIL, the frequencies of HR-HPV 52,16,58,18 were 19.3,18.2,10.9, and 7.8%, respectively. Conclusion Our study provides important data about the HPV genotype distribution and its correlation with cervical intraepithelial lesions in the Wenzhou population.

Abstract
BACKGROUND Human papillomavirus (HPV) infection can lead to the development of cervical cancer. This study assessed the genotype distribution of HPV of high-grade squamous intraepithelial lesion (HSIL) and invasive cervical cancer (ICC) in Ganzhou population. METHODS A total of 935 females who got HPV testing from January 2016 to July 2018 in the maternal and child health hospital of Ganzhou were enrolled in the study, including 806 HSIL and 129 ICC. HPV detection and genotyping were tested by HPV Geno-Array test kit. RESULTS The overall HPV-positive rate was 74.0% in Ganzhou. Among the HSIL and ICC patients, the positive rates of HPV detection were 75.6% and 64.3%. Among the HSIL individuals, the most prevalent hr-HPV genotype was HPV 16. And the 4 common subtypes in decreasing order were HPV 52, 58, 33, and 18. Of the ICC patients, the most frequently hr-HPV subtype was HPV 16 followed by 18, 52, 58, and 59. Among the squamous cell carcinoma (SCC) patients, for hr-HPV genotypes, HPV 16, 18, 52, 58, and 59 were five most common subtypes. In patients with adenocarcinoma (ADC), the most common hr-HPV genotype was HPV 18, followed by HPV 16, 52, 56, 68, 73. And, we found U-shaped and S-shaped curves in the HPV distribution of different age groups. CONCLUSION The prevalence and distribution of HPV genotypes in Ganzhou differed from other regions of China and Western countries. These results can serve as valuable reference for HPV vaccination programs for Ganzhou women.

Abstract
Several viruses are recognized as the direct or indirect causative agents of human tumors and other severe human diseases. Vascular endothelial growth factor (VEGF) is identified as a principal proangiogenic factor that enhances the production of new blood vessels from existing vascular network. Therefore, oncogenic viruses such as Kaposi’s sarcoma herpesvirus (KSHV) and Epstein-Barr virus (EBV) and non-oncogenic viruses such as herpes simplex virus (HSV-1) and dengue virus, which lack their own angiogenic factors, rely on the recruitment of cellular genes for angiogenesis in tumor progression or disease pathogenesis. This review summarizes how human viruses exploit the cellular signaling machinery to upregulate the expression of VEGF and benefit from its physiological functions for their own pathogenesis. Understanding the interplay between viruses and VEGF upregulation will pave the way to design targeted and effective therapeutic approaches for viral oncogenesis and severe diseases.

Abstract
To add the growing literature on baseline of high-risk human papillomavirus (HR-HPV) genotype distribution in cervical intraepithelial neoplasia (CIN) before the widespread using of HPV vaccines in Chinese mainland and to improve risk stratification of HR-HPV-positive women. Retrospectively, the data of age, cervical HPV genotypes, cytology, and pathology were collected from 1166 patients who received loop electrosurgical excision procedure (LEEP). HPV genotypes were analyzed with Flowcytometry Fluorescence Hybridization Method. And then HPV prevalence, HR-HPV genotype distribution and the correlation of HR-HPV genotypes with CIN2+ (CIN2 or severer) were analyzed. The role of multiple HR-HPV types infection with or without HPV16/18 in the pathogenesis of CIN2+ was also analyzed. The 6 most common HR-HPV genotypes were HPV16, 58, 52, 33, 18, and 31 in descending order. Compared to HR-HPV-negative women, HPV16, 33 or 58 positive women had higher risk of CIN2+ (OR = 5.10, 95% CI = 2.68-9.70; OR = 3.09, 95% CI = 1.39-6.84; OR = 3.57, 95% CI = 1.85-6.89, respectively). And women who were infected by multiple HR-HPV types infection with HPV16/18 also had higher risk of CIN2+ (OR = 2.58, 95% CI = 1.35-4.92). However, multiple HR-HPV types infection without HPV16/18 did not increase the risk significantly (P = .08). Compare to bivalent Cervarix® and quadrivalent Gardasil® , HPV prophylactic vaccine targeting HPV31, 33, 52, and 58 might provide women more protection from HPV-induced cervical cancer in China. The women who infected by HPV16, 33, 58, or multiple HR-HPV types with HPV16/18 have higher risk of CIN2+ and need to be paid more attention in screening processes. And the role of multiple HR-HPV types infection without HPV16/18 needs be further identified in more studies.

Abstract
Cervical human papillomavirus (HPV) infection is a dangerous disease, whose subtypes exhibit different distribution patterns in particular countries, regions, and races. In this study, the HPV distribution in patients with cervical precancerous lesions in Western China was investigated to assess a probability for prevention of cervical cancer and the clinical application of an HPV vaccine in China. The retrospective study of patients with different HPV subtypes and cervical precancerous lesions, who have undergone loop eelectrosurgical excision procedure, cold knife conization, or a total hysterectomy in our hospital from January 2016 to August 2016, was performed. All patients were tested for 27 HPV subtypes via the liquid suspension chip technology (Luminex 200). A total of 3393 cases of cervical intraepithelial neoplasia (CIN) were investigated, including 1098 cases of CIN I, 762 cases of CIN II, and 1533 cases of CIN III. The overall HPV infection rate was 82.58%. The high-risk HPV infection rate was 76.61%, and the low-risk rate was 9.88%. The most common 5 subtypes were HPV16, HPV52, HPV58, HPV33, and HPV18. The patients were grouped into 6 age groups: ≤20, 21 to 30, 31 to 40, 41 to 50, 50 to 64, and ≥65. The HPV subtypes' distribution varied across different age groups. In patients with cervical precancerous lesions in Western China, the top 5 HPV subtypes with the highest infection rates were HPV16, HPV52, HPV58, HPV33, and HPV18. The rate of cervical precancerous lesions unrelated to HPV was 17.42%. Thus, HPV screening with no cytology may leave unobserved about 20% of cervical precancerous lesions, which is worth of significant clinical attention.

Abstract
Head and neck cancers (HNCs) are a highly heterogeneous group of tumours that are associated with diverse clinical outcomes. Recent evidence has demonstrated that human papillomavirus (HPV) is involved in up to 25% of HNCs; particularly in the oropharyngeal carcinoma (OPC) subtype where it can account for up to 60% of such cases. HPVs are double-stranded DNA viruses that infect epithelial cells; numerous HPV subtypes, including 16, 18, 31, 33, and 35, drive epithelial cell transformation and tumourigenesis. HPV positive (HPV+) HNC represents a distinct molecular and clinical entity from HPV negative (HPV-) disease; the biological basis for which remains to be fully elucidated. HPV positivity is strongly correlated with a significantly superior outcome; indicating that such tumours should have a distinct management approach. This review focuses on the recent scientific and clinical investigation of HPV+ HNC. In particular, we discuss the importance of molecular and clinical evidence for defining the role of HPV in HNC, and the clinical impact of HPV status as a biomarker for HNC.
