RESUMO
OBJECTIVE: The aim of this study was to identify the molecular prevalence of high-risk HPV infection and the distribution of genotypes present in normal cytology, as well as to determine the vaccination status of our study population. METHODS: 110 cervical samples were taken from individuals, and 1 ml of each sample was added to the Xpert HPV cartridge in the sample compartment before it was placed in the Cepheid GeneXpert system. Detection was performed simultaneously via amplification of the E6 and E7 genes in five fluorescent channels (HPV16, HPV18/45, HPV31/33/35/52/58, HPV51/59, and HPV39/56/66/68a). RESULTS: 36/110 (33%) of all samples tested were positive for HPV DNA. The predominant genotypes were HPV16 (12.7%) and other pooled HR-HPV types (8.2%). All women who received the Gardasil-9 vaccine (3.6%) had HPV, and infection was associated with travel outside Africa. 96.4% of the screened individuals had not received any HPV vaccine. CONCLUSION: Our research confirms a widespread HR-HPV infection in our population and extends the importance of studies on the molecular prevalence of HPV, particularly in women with normal cytology and apparent good health, in view of the cruel lack of public awareness of HPV infections.

Background: In this study, we characterized the HPV genotype distribution in a population of 489 adults already positive for HPV DNA. The study population was divided into two groups: 244 HIV-positive (HIV+) men who have sex with men (MSM) undergoing routine anal screening for sexually transmitted diseases (STDs) and 245 women undergoing routine cervical cancer screening. Acknowledging the fact that women and MSM represent two independent circles of sexual practices, which are-largely-exclusive of each other, we were interested in determining if particular genotypes of human papillomavirus (HPV) disproportionately predominate in one of these circles compared to the other. Results: HIV+ MSM are significantly more likely to be infected with multiple genotypes at a time, with an odds ratio (OR) of 9.30 (95% confidence interval [CI]: 3.91-22.1) and a p-value of <0.001. In addition, multivariable-adjusted logistic regression analysis showed that anal swab samples were significantly more likely to harbor lrHPV infections, with an OR of 6.67 (95% CI: 2.42-18.4) and a p-value of <0.001, in particular, HPV 6, with an OR of 8.92 (95% CI: 3.84-20.7) compared to cervical samples of screening women. Conclusion: Given the significant impact of recurrent anogenital warts (AGWs) on quality of life and the accompanying predisposition to invasive anal cancer, our data underscore the critical need for HPV vaccination. This includes expanding vaccination eligibility to include both boys and adults within high-risk populations.

BACKGROUND: Quality assessment of the prevalence and distribution of human papillomavirus (HPV) genotypes could support additional targeted HPV vaccinations. However, the characteristics of HPV infection in Wuhan city are limited in the past decade. We aimed to assess the epidemiology of HPV infection among women and provide a reference for the prevention and treatment of cervical cancer in this region. METHODS: A retrospective study employing 105,679 women attending Wuhan Medical and Health Center for Women and Children for cervical cancer screening from January 2015 to December 2022 was conducted. The HPV genotype was detected by polymerase chain reaction (PCR) and diversion hybridization. The overall incidence and age-specific type distribution of HPV infection and the relationship between HPV infection and cervical cytology were analyzed. RESULTS: The overall HPV infection rate was 16.87% in Wuhan city, and the prevalence rates of high-risk, low-risk and mixed high- and low-risk HPV infections were 13.64%, 1.77% and 1.46%, respectively. The five most prevalent genotypes were HPV52 (4.24%), HPV58 (2.42%), HPV16 (2.34%), HPV53 (1.87%), and HPV39 (1.66%). The prevalence of HPV in women exhibited a "two-peak" pattern, the peaks of which were observed in the < 21 years group (37.4%) and the 61-65 years group (41.72%). Logistic regression analysis revealed no significant difference in the rate of high-grade lesion positivity between single and multiple high-risk HPV infections. Among patients with a high-grade squamous intraepithelial lesion+ (HSIL+) ThinPrep cytologic test (TCT) diagnosis, HPV58 was the most common type, followed by HPV52, HPV16, HPV39 and HPV53. CONCLUSIONS: HPV types 52, 58, 16, 53, and 39 were the most common types in the general female population in Wuhan, and the prevalence of HPV infection varied among different age groups. This study provides a comprehensive overview of the epidemiological characteristics of HPV infection in women, which could support the development of targeted prevention and control strategies for cervical cancer in the region.

BACKGROUND: Human papillomavirus (HPV), is one of the main causes of cervical cancer and also one of the most common sexually transmitted infections (STIs). HPV is responsible for almost all cases of cervical cancer and plays a principal role in causing other cancers including oropharynx, penis, larynx, oral cavity, anus, vulva, and vagina. The study aims to investigate the prevalence and distribution of HPV genotypes among patients referred to private laboratories in Mashhad, located in the northeast of Iran. METHODS AND MATERIALS: 428 samples including 382 females (89.3%) and 46 males (10.7%) between January 10, 2022, and February 11, 2023, in Mashhad, Iran were evaluated to detect HPV and determine its genotypes. Cervical swabs and urine samples were collected from females and males, respectively. Viral DNA was extracted by using a CedExtra purification kit (cedbio, Iran) and viral genotypes were identified with a High + Low Papillomastrip kit (Operon, Spain). Mann Whitney U test and Chi-square test were accomplished for statistical analysis. RESULT: From the total of 428 participants analyzed, the HPV test result was positive for 129 patients (30.1%) and negative for 299 people (69.9%). Among the participants, 115 female (30.1%) and 14 male (30.4%) were positive for HPV infection. The prevalence of HPV infection among the referring people was about 30%. The most common genotype identified was HPV-6 (10.3%), followed by HPV-16 (8.7%) and HPV-51 (7.7%), the second and third most common genotypes, respectively. Additionally, HPV-39 was detected at a frequency of 6.70%. HPV-11, HPV-61, HPV-91, and HPV-44 with a frequency of 1% were among the least genotypes identified among the patients. CONCLUSION: In line with the results of this study, the prevalence of HPV genotypes in both genders is 30%. The results likely reflect differences in the prevalence of high-risk HPV genotypes, that are less common. Also, HPV-6 and HPV-16 genotypes that are covered by the vaccine had a significant prevalence. On the other hand, with the prevalence of HPV-51 and HPV-39 genotypes in infected people who are not covered by the Gardasil (quadrivalent) vaccine, there is a risk of related cancers in the future.

Human papillomavirus (HPV) is the most prevalent sexually transmitted infection among teenagers and young adults. HPV vaccination and screening are vital preventive measures to reduce the incidence of HPV-related complications, including cervical cancer. Given the rising global incidence of cervical cancer, understanding the factors influencing awareness and knowledge among young adults in Saudi Arabia is essential for developing effective prevention strategies. This study investigates the levels of awareness, knowledge, and vaccine acceptability regarding HPV and cervical cancer among college students in Saudi Arabia. A cross-sectional study was conducted between May and September 2023 among 442 students in Saudi Arabia using a structured questionnaire to assess their knowledge and awareness of HPV, HPV vaccination, and cervical cancer. Multivariate logistic regression analysis was employed to examine the associations between predictor and dependent variables. Among participants, 54.1% were aware of HPV, and 66.5% had heard of cervical cancer. However, only 17% correctly identified HPV16 and HPV18 as high-risk genotypes for cervical cancer. Awareness of the HPV vaccine was reported by 36.2% of participants, with just 10% having received the vaccine. Female students exhibited significantly higher knowledge levels than males (p = .018). The primary barrier to vaccination was identified as a lack of education and awareness (80.1%). The study highlights a significant gap in knowledge and awareness regarding HPV, its vaccine, and cervical cancer among college students in Saudi Arabia. Targeted educational programs and awareness campaigns are essential to enhance understanding and promote preventive practices, including vaccination and regular screening.

Human Papilloma Virus (HPV) is an oncogenic virus and is the most common cause of cervical cancer. HPV has been shown to induce senescence. Cellular senescence is involved in cancer progression and tumorigenesis. Identification and isolation of cells of tumor origin before tumorigeneses is an important step in cancer prevention and treatment. This study aimed to investigate the early cervical atypical senescent cytological preneoplastic change in non-menopausal women. Cervical smears of 121 patients were randomly selected and included in the study which cytopathologically diagnosed as atypical squamous cells of undetermined significance (AS-CUS) in correlation to HPV status, parakeratosis (PK), p16 immunostaining, enlarged Squamous cells nuclei (ES) and inflammatory cells infiltration (ICI). Results revealed that out of the total 121 patients, 32 cases (26%) were positive for high-risk HPV (HR-HPV), 26 cases (22%) were positive for low-risk HPV (LR-HPV) and 63 (52%) were negative for HPV. HPV infections were significantly associated with age groups (p<0.026), PK (p = 0.043), p16 (p = 0.001), ES (p = 0.002) and ICI (p = 0.049). The positive immunostaining expression of p16 was only noticed in two HR-HPV patients. ES cells were found in 9.5% of HPV-negative cases, 27% of LR-HPV cases and 40.5% of HR-HPV cases. High PK cell positivity was seen only in HR-HPV. High ICI scores were seen in 40.6% of HR-HPV patients, 26.9 % of LR-HPV and 17.4 % of negative HPV patients. It was concluded that high PK positivity, high ICI score, positive p16 immunostaining and ES were correlated with HR-HPV in non-menopausal women. These findings could provide potential diagnostic clues for HPV-harboring senescent cells as a strategy for reducing HPV risk of cervical cancer development and identifying the cell of tumor origin, which could be beneficial for improving the utility of senolytic agents and immunotherapy in clinical practice.

This systematic review aims to determine whether the presence of human papillomavirus (HPV) influences the immunohistochemical expression of programmed cell death-1 ligand (PD-L1) in oropharyngeal squamous cell carcinoma (OPSCC). PD-L1 immunohistochemical expression varies in OPSCC, and the presence of HPV is a plausible explanation for this variability. Comprehending these findings is crucial, as high PD-L1 expression in the tumor microenvironment of OPSCC can help identify patient subgroups that could be suitable for immunotherapy. Therefore, a systematic review was conducted following PRISMA guidelines (CRD42023437800). An electronic literature search was performed without time or language restrictions. The search included PubMed/MEDLINE, Embase, Scopus, Web of Science, https://clinictrials.gov, and relevant journals. A meta-analysis was performed using RStudio. Fourteen studies involving 1,629 participants were included. The sample consisted predominantly of males (81.26%) with a mean age of 58.3 years. Concerning clinical and pathological characteristics, the most frequently described anatomical location was the tonsils (68.54%), and most participants were either current or former smokers (78%) and alcohol users (79%). Advanced TNM IV was the most common stage. Regarding histopathological characteristics, HPV 16 was the only type mentioned, and half of the cases were detected through immunohistochemistry. The SP142 clone (35.7%) and the pattern of membrane immunostaining in tumor cells (71%) were the most commonly employed methods. The most prevalent findings were positive expression of PD-L1 (64.28%) and negative HPV status (57.14%). The association between PD-L1 positivity and HPV positivity (78.57%) was confirmed by meta-analysis. The conclusion was that HPV-positive status has an impact on immunohistochemical expression of PD-L1 in OPSCC.

BACKGROUND: Variant analysis of distinct HPV types is important from different aspects including epidemiology, pathogenicity, and evolution. METHODS: For this reason, the full sequence of the E6 and E7 genes of HPV 58 was examined in 130 HPV 58-infected cervical samples using PCR and sequencing. RESULTS: Our results revealed that three lineages A, B, and D were found in this study; among which the B lineage was more common (91.50%). About sublineages, all samples of the B lineage belonged to the B1 sublineage, and samples that were classified as the A and D lineages were found to belong to the A1 (0.77%), A2 (5.38%), A3 (1.50%), and D2 (0.77%) sublineages. No statistically significant differences were found between lineages and stages of disease or amino acid changes (P > 0.05). CONCLUSION: Our results showed that lineage B, sublineage B1, was dominant in Iran. However, more studies with larger sample sizes from different parts of Iran are essential for assessing the pathogenicity risk of HPV 58 lineages in Iranian women with cervical cancer.

Immune evasion represents a crucial milestone in the progression of cancer and serves as the theoretical foundation for tumor immunotherapy. In this study, we reveal a negative association between Human Papillomavirus (HPV)-encoded circular RNA, circE7, and the infiltration of CD8+ T cells in head and neck squamous cell carcinoma (HNSCC). Both in vitro and in vivo experiments demonstrate that circE7 suppresses the function and activity of T cells by downregulating the transcription of LGALS9, which encodes the galectin-9 protein. The molecular mechanism involves circE7 binding to acetyl-CoA carboxylase 1 (ACC1), promoting its dephosphorylation and thereby activating ACC1. Activated ACC1 reduces H3K27 acetylation at the LGALS9 gene promoter, leading to decreased galectin-9 expression. Notably, galectin-9 interacts with immune checkpoint molecules TIM-3 and PD-1, inhibiting the secretion of cytotoxic cytokines by T cells and promoting T cell apoptosis. Here, we demonstrate a mechanism by which HPV promotes immune evasion in HNSCC through a circE7-driven epigenetic modification and propose a potential immunotherapy strategy for HNSCC that involves the combined use of anti-PD-1 and anti-TIM-3 inhibitors.

Human Papilloma Virus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is a distinct disease from other head and neck tumors. This guideline provides evidence-based recommendations on the critical decisions in its curative treatment, including both definitive and postoperative radiation therapy (RT) management. ASTRO convened a task force to address 5 key questions on the use of RT for management of HPV-associated OPSCC. These questions included indications for definitive and postoperative RT and chemoradiation; dose-fractionation regimens and treatment volumes; preferred RT techniques and normal tissue considerations; and posttreatment management decisions. The task force did not address indications for primary surgery versus RT. Recommendations were based on a systematic literature review and created using a predefined consensus-building methodology and system for grading evidence quality and recommendation strength. Concurrent cisplatin is recommended for patients receiving definitive RT with T3-4 disease and/or 1 node >3 cm, or multiple nodes. For similar patients who are ineligible for cisplatin, concurrent cetuximab, carboplatin/5-fluorouracil, or taxane-based systemic therapy are conditionally recommended. In the postoperative setting, RT with concurrent cisplatin (either schedule) is recommended for positive surgical margins or extranodal extension. Postoperative RT alone is recommended for pT3-4 disease, >2 nodes, or a single node >3 cm. Observation is conditionally recommended for pT1-2 disease and a single node ≤3 cm without other risk factors. For patients treated with definitive RT with concurrent systemic therapy, 7000 cGy in 33 to 35 fractions is recommended, and for patients receiving postoperative RT without positive surgical margins and extranodal extension, 5600 to 6000 cGy is recommended. For all patients receiving RT, intensity modulated RT over 3-dimensional techniques with reduction in dose to critical organs at risk (including salivary and swallowing structures) is recommended. Reassessment with positron emission tomography-computed tomography is recommended approximately 3 months after definitive RT/chemoradiation, and neck dissection is recommended for convincing evidence of residual disease; for equivocal positron emission tomography-computed tomography findings, either neck dissection or repeat imaging is recommended. The role and practice of RT continues to evolve for HPV-associated OPSCC, and these guidelines inform best clinical practice based on the available evidence.

While HC2 and GP5+/6+ PCR-EIA were pivotal in test validation of new HPV assays, they represent the first generation of comparator tests based upon technologies that are not in widespread use anymore. In the current guideline, criteria for second-generation comparator tests are presented that include more detailed resolution of HPV genotypes. Second-generation comparator tests should preferentially target only the 12 genotypes classified as carcinogenic (IARC-group I), and show consistent non-inferior sensitivity for CIN2+ and CIN3+ and specificity for ≤CIN1 compared to one of the first-generations comparators, in at least three validation studies using benchmarks of 0.95 for relative sensitivity and 0.98 for relative specificity. Validation should take into account used storage media and other sample handling procedures. Meta-analyses were conducted to identify the assays that fulfill these stringent criteria. Four tests fulfilled the new criteria: (1) RealTime High-Risk HPV Test (Abbott), (2) Cobas-4800 HPV test (Roche Molecular System), (3) Onclarity HPV Assay (BD Diagnostics), and (4) Anyplex II HPV HR Detection (Seegene), each evaluated in three to six studies. Whereas the four assays target 14 carcinogenic genotypes, the first two identify separately HPV16 and 18, the third assay identifies five types separately and the fourth identifies all the types separately.

Seroepidemiological characteristics of human papillomavirus (HPV) in community residents reflect natural infection and can guide the reform of vaccination programs. A population-based serological survey was conducted in Guangdong Province. Serum anti-HPV IgG antibody levels were determined by an ELISA. Neutralizing antibodies against HPV6, 11, 16, and 18 were detected via a pseudovirus-based neutralization assay (PBNA). A total of 5122 serum samples were collected from community residents, including 1989 males and 3133 females, in three cities of Guangdong Province. The rate of HPV IgG antibody positivity in females was 5.39% (95% CI: 4.6-6.2), which was greater than that in males (2.36%; 95% CI: 1.7-3.1). HPV IgG antibodies were more frequently detected in females aged 51-60 years (11.30%; 95% CI: 7.6-16.0), whereas in males, the detection increased with age and reached 4.94% (95% CI: 2.8-6.9) in the group aged ≥71 years. The seropositivity of neutralizing antibodies against HPV6 and 11 was greater than that against HPV16 and 18. The serum neutralizing antibody titers in individuals who received three doses of a vaccine were 7- to 12-fold greater than those in individuals who did not receive the vaccine. The neutralizing antibody titers slightly decreased within 40 months and ranged from 0.038 to 0.057 log ED50 per month. A moderate consistency between the HPV ELISA and PBNA results was observed (Kappa score = 0.49, r = 0.249, 0.635, 0.382, and 0.466 for HPV6, 11, 16, and 18, respectively). The HPV seropositivity rate among healthy residents of Guangdong Province was found to be low among children and adolescents and to increase with age. The serum neutralizing antibody titers were significantly greater in the vaccine group than that in the control group, and this difference persisted over time, which indicated promising protection against HPV infection.

Sexually transmitted infections (STIs) have a profound impact on sexual and reproductive health worldwide. Syphilis, gonorrhea, chlamydia, and trichomoniasis are four currently curable STIs. However, most STI cases are asymptomatic and not detected without laboratory diagnostics. Hepatitis B virus, herpes simplex virus, human immunodeficiency virus (HIV), and human papillomavirus (HPV) are four viral and incurable infections, but they can be mitigated by treatment. We investigated the prevalence of selected sexually transmitted pathogens and their relationship with HPV and HIV infection in women from Maputo, the capital of Mozambique. A cross-sectional study was conducted on 233 non-pregnant women seeking health care relating to gynecological symptoms in Mavalane Health facilities in Maputo, between the 1st of February 2018 and the 30th of July 2019. Cervical brush samples were collected and DNA was extracted. Selected STIs including HPV were detected using multiplex STD and HPV Direct Flow Chip Kits through a manual Hybrispot platform (Vitro, Master Diagnostica, Sevilla, Spain). HIV testing was performed using rapid tests: Determine HIV 1/2 test (Alere Abbott Laboratories, Tokyo, Japan) for screening, and UniGold HIV (Trinity Biotech, Ireland) for confirmation. All women (n = 233) were negative for Haemophilus ducreyi and Herpes Simplex Virus-1 (HSV-1). Among the 233 women, a high prevalence of STIs was found (89%), 63% of the women were positive for HPV and 24% were HIV positive. Treponema pallidum (TP), Trichomonas vaginalis (TV), Herpes Simplex Virus-2 (HSV-2), and Chlamydia trachomatis (CT) were detected in 17%, 14%, 8%, and 8% of the women, respectively. As a common phenomenon, vaginal discharge (90%) was the lower genital tract symptom reported by the majority of the women. Co-infection with any STI and HPV was detected in 56% (130/233) while 45% (59/130) of the co-infections were with high-risk HPV (hrHPV) genotypes. Among the HPV-positive participants, infection by TP was the most prevalent (27%). In total, 28% (66/233) of the participants were positive for any hrHPV genotypes. Co-infection with any STI and HIV was found in 15% (34/233) of the study participants. There was a significant association between HPV infection and TP (p = 0.039) and HSV-2 (p = 0.005). TV, TP, and CT-S1-CT-S2 positivity were significantly more prevalent in HIV-positive participants. Pathobionts Ureaplasma urealyticum/parvum and Mycoplasma hominis were detected in 84.0% (195/233) and 45% (105/233), respectively. This present study describes a high prevalence of STIs. Co-infection between HPV and STIs was found in the majority of the study subjects. The high prevalence of HPV emphasizes the need for HPV vaccination to prevent cervical cancer in this population. Management of STIs is also important in women presenting with gynecological symptoms.

Objective: Patients with pathogenic variants in the GATA Binding Protein 2 (GATA2), a hematopoietic transcription factor, are at risk for human papillomavirus-related (HPV) anogenital cancer at younger than expected ages. A female cohort with GATA2 haploinsufficiency was systematically assessed by two gynecologists to characterize the extent and severity of anogenital HPV disease, which was also compared with affected males. Methods: A 17-year retrospective review of medical records, including laboratory, histopathology and cytopathology records was performed for patients diagnosed with GATA2 haploinsufficiency followed at the National Institutes of Health. Student's t-test and Mann-Whitney U test or Fisher's exact test were used to compare differences in continuous or categorical variables, respectively. Spearman's rho coefficient was employed for correlations. Results: Of 68 patients with GATA2 haploinsufficiency, HPV disease was the initial manifestation in 27 (40%). HPV occurred at median 18.9 (15.2-26.2) years in females, and 25.6 (23.4-26.9) years in males. Fifty-two (76%), 27 females and 25 males, developed HPV-related squamous intraepithelial lesions (SIL) including two males with oral cancer. Twenty-one patients developed anogenital high-grade SIL (HSIL) or carcinoma (16 females versus 5 males, (59% versus 20%, respectively, p=0.005) at median 27 (18.6-59.3) years for females and 33 (16.5-40.1) years for males. Females were more likely than males to require >2 surgeries to treat recurrent HSIL (p=0.0009). Of 30 patients undergoing hematopoietic stem cell transplant (HSCT) to manage disease arising from GATA2 haploinsufficiency, 12 (nine females, three males) had persistent HSIL/HPV disease. Of these nine females, eight underwent peri-transplant surgical treatment of HSIL. Five of seven who survived post-HSCT received HPV vaccination and had no or minimal evidence of HPV disease 2 years post-HSCT. HPV disease persisted in two receiving immunosuppression. HPV disease/low SIL (LSIL) resolved in all three males. Conclusion: Females with GATA2 haploinsufficiency exhibit a heightened risk of recurrent, multifocal anogenital HSIL requiring frequent surveillance and multiple treatments. GATA2 haploinsufficiency must be considered in a female with extensive, multifocal genital HSIL unresponsive to multiple surgeries. This population may benefit from early intervention like HSCT accompanied by continued, enhanced surveillance and treatment by gynecologic oncologists and gynecologists in those with anogenital HPV disease.

Background: In the general population, primary human papillomavirus (HPV) testing is advocated for cervical cancer (CC) screening. HPV E6/E7 mRNA (Aptima HPV, AHPV) assays have garnered considerable traction due to their higher specificity when compared with HPV DNA assays. Here, we investigated age-specific primary AHPV screening assays and different triage strategies versus cytology to identify the best approach. Methods: Between April 2018 and December 2021, we recruited female participants from 34 communities across Liaoning province and Qingdao City, China. Primary cervical screening protocols included liquid-based cytology (LBC) and AHPV assays, with females positive for any assays undergoing colposcopy. Genotyping (AHPV-GT) was conducted on all HPV-positive samples. Our primary outcomes were the identification of age-specific detection rates, colposcopy referral rates, and sensitivity and specificity values for high-grade squamous intraepithelial lesions or worse (HSIL+). AHPV and different triage strategy performances were also examined across different age cohorts. Results: Our investigation included 9911 eligible females. Age-specific abnormal cytology rates were in the 6.1%-8.0% range, and were highest in 45-54-year olds. When compared with 35-44-or 45-54-year olds, HPV prevalence was highest in 55-64-year olds (12.2% or 11.6% vs.14.1%, P = 0.048 and P = 0.002, respectively). In 35-44-year olds, AHPV sensitivity for detecting HSIL+ was 96.6 (95% confidence interval [CI]: 89.7-100) - significantly higher than LBC sensitivity (65.5 [95% CI: 48.3-82.8], P < 0.001). When compared with LBC, HSIL+ detection rates by AHPV-GT using reflex LBC triage increased by 31.5% (9.6 vs. 7.3), and colposcopy referral rates decreased by 16.4% (5.1% vs. 6.1%). In 45-54-year olds, HSIL+ detection rates for AHPV-GT using reflex LBC triage were lower than LBC rates (6.2 vs. 6.6). In 55-64-year olds, AHPV sensitivity (97.2 [95% CI: 91.7-100.0]) was higher than LBC sensitivity (66.7 [95% CI: 50.0-80.6], P = 0.003). The area under the curve (AUC) value was not significantly different between AHPV-GT with reflex LBC triage and LBC (0.845 [95% CI: 0.771-0.920] vs. 0.812 [95% CI: 0.734-0.891], P = 0.236). Conclusions: Primary AHPV screening using different triage strategies were different across different age cohorts. Thus, AHPV may be an appropriate primary screening method for 35-44 and 55-64 year old females, while AHPV-GT with reflex LBC triage may be more apt for 35-44 year old females.

To compare the clearance rate of high-risk human papillomavirus (HR-HPV) in patients with high-grade squamous intraepithelial lesion (HSIL) after 2 different treatments (conization vs hysterectomy), and investigate the influencing factors. A retrospective cohort was established in HSIL patients with HR-HPV infection treated with conization or hysterectomy from July 2020 to May 2022. Age matching (1:1) was conducted between conization group and hysterectomy group. Chi-square test and t-test were employed to compare baseline and clinical characteristics between the 2 groups (conization vs hysterectomy). In addition, univariate and multivariate logistic regression analyses were conducted to compare the influencing factors for HR-HPV clearance at 6 months after surgery. The HR-HPV clearance rates at 6 months were 70.6% and 73.8% in conization group and hysterectomy group in the matched groups, respectively (Pâ =â .755). Similarly, at 12 months, the clearance rates were 78.6% and 76.5% in the matched groups, respectively (Pâ =â .844). Considering different age groups among all patients, the HR-HPV clearance rates were 81.8%, 72.9%, 73.5%, and 53.6% in the 20 to 30-year, 31 to 40-year, 41 to 50-year and 51 to 60-year groups at 6 months, respectively, and the clearance rates were 87.5%, 80.6%, 84.5% and 52.9% at 12 months, respectively. For HSIL, the postoperative HPV clearance rates were similar between the 2 groups (conization vs hysterectomy), conization is enough to resect the lesion and eliminate HPV. In addition, we should pay attention to the postoperative HR-HPV status in the older population of the 2 groups.

Mohs micrographic surgery is the gold standard for treating many types of skin cancer, particularly skin cancers of high-risk areas such as the face, genitalia, and digits, due to its tissue-sparing technique and low recurrence rates. The use of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies has yet to be explored in a systematic review. The authors sought to assess outcomes including recurrence rates of Mohs micrographic surgery for human papilloma virus-associated cutaneous malignancies. PubMed was searched for the use of Mohs micrographic surgery in types of human papilloma virus-associated cutaneous malignancies. After application of exclusion and inclusion criteria, 33 articles were included. 700 cases from 33 studies were included. Overall recurrence rate following Mohs micrographic surgery was 39/478 (8.2%) at a mean follow-up time of 51.5 months. Recurrence rate for nail unit/digit squamous cell carcinoma was 10/103 (9.7%) at mean follow-up of 47.6 months. Recurrence rate for penile squamous cell carcinoma was 15/181 (8.3%) at mean follow-up of 45.9 months. Recurrence rate for Bowen's disease in extragenital areas was 11/189 (5.9%) at mean follow-up of 59.7 months. Patients overall reported satisfactory functional and cosmetic results. Mohs micrographic surgery demonstrates low recurrence rates and excellent functional and cosmetic outcomes in the treatment of human papilloma virus-associated cutaneous malignancies.

The optimal treatment of oropharyngeal cancer (OPC) associated with human papillomavirus (HPV) is currently a subject of clinical research. This questionnaire study investigated current trends in the treatment of HPV-associated (HPV+) OPC in Slovakia with the incorporation of deintensification of oncological treatment into routine clinical practice outside of clinical trials. The Slovak Cooperative Head and Neck Cancer Group (SCHNCG) developed a questionnaire aimed at identifying trends in the oncological treatment of HPV+ OPC intended for all radiation oncology (RO) facilities in Slovakia. Specialists in the field of RO responded to general questions about the character of their individual institutions as well as to 4 theoretical clinical scenarios (case reports) regarding the treatment of HPV+ OPC, focusing primarily on the applied dose of radiotherapy (RT), the extent of target volumes, and the type of concurrent chemotherapy (CHT). The questionnaire study involved 35 RO specialists from 14 institutions in Slovakia. Regarding primary chemoradiotherapy (CRT) in T1N1M0 HPV+ OPC, 16 respondents (45.7%) would consider de-escalation of the RT dose to <70 Gy. In the case of postoperative RT in pT1pN1M0 HPV+ OPC with negative resection margins (R0) and absent extracapsular extension (ECE), 4 physicians (11.4%) would consider de-escalation of the RT dose to <60 Gy in the tumor bed area, while the majority of the treating specialists (n=19, 54.3%) would omit concurrent CHT. In the case of primary RT in elderly patient with T2N1M0 HPV+ OPC, the same number of physicians (n=16, 45.7%) would consider de-escalation of the RT dose to <70 Gy, and 14 respondents (40.0%) would completely omit CHT. In a high-risk patient with T2N3M0 HPV+ OPC with a complete response after 3 cycles of induction chemotherapy (iCHT), none of the respondents would indicate a reduction in the RT dose to the area of the original tumor and lymphadenopathy to <60 Gy. The doses and extent of irradiated volumes in the treatment of HPV+ OPC in Slovakia vary among different institutions. The tendency to de-escalate RT doses and reduce doses of concurrent systemic therapy in Slovakia is high and there was also an observed trend to reduce the extent of radiation treatment fields.

The prevalence of human papillomavirus (HPV) genotype and cervical neoplasia in women older than 64 years, who are outside the age demographic of cervical cancer screening in China, has been under-researched. This study conducts a retrospective analysis of women from a tertiary hospital in Guangzhou, with the aim to offer valuable insights for cervical cancer prevention and control in elderly women. The study incorporated 876 women, all aged 64 and above. In this age bracket, the prevalence rate of any HPV genotype was found to be 19.27%. The top six HR HPV genotypes were HPV 16, HPV 52, HPV 58, HPV 31, HPV 33, and HPV 18. The persistence rate of any HPV type over a 24-month period in this age group was as high as 33.33%. Among women over 64, around 16.47% of HPV-positive patients were diagnosed with cervical cancer. HPV 58 infection was the most substantial risk factor for histological CIN2+ (OR 3.556; 95% CI, 1.107-11.415; p = 0.032) in women over 64 years of age with HPV-positive/NILM status. In conclusion, the burden of HPV infection is significant among women over 64 years in Guangzhou. Re-evaluation of cervical cancer screening strategies for women after the age of 64 is imperative. Moreover, the HPV 16/18/52/58 genotype model could serve as an alternative triage approach to identify histological CIN2+ among elderly women with HPV-positive/NILM status.
Elderly women exhibit an elevated risk of contracting HPV infection and developing cervical lesions.HPV 58 is notably associated with the progression of CIN2+ among women aged above 64 years with HPV-positive/NILM status.HPV 16/18/52/58 genotype model presents an alternative triage approach for identifying CIN2+ among women aged above 64 years with HPV-positive/NILM status.

BACKGROUND: A persisting high-risk human papillomavirus (HR-HPV) infection is causal for cervical cancer; however, there is limited population-based data on the prevalence of HPV infections in Germany. We assessed the age and type-specific HPV prevalence, and associated risk factors in HPV unvaccinated women aged 30 and above. METHODS: The MARZY prospective population-based cohort study was conducted between 2005 and 2012 in Mainz and Mainz-Bingen, Germany. Eligible women were randomly recruited from population registries and invited for cervical cancer screening (n = 5,275). A study swab (liquid-based cytology) was taken and HPV testing was performed with GP5+/6 + polymerase chain reaction (PCR) followed by genotyping. We assessed HPV types as HR-HPV, 'moderate' risk and low-risk (LR-HPV). Logistic regression was performed to identify factors associated with HPV infection, stratified by HPV types. RESULTS: 2,520 women were screened with a valid PCR result. Overall HPV prevalence was 10.6% (n = 266), with 6.5% HR-HPV positive (n = 165), 1.5% 'moderate' risk type (n = 38) and 3.3% LR-HPV type (n = 84) positive. 8.9% had a single infection (n = 225) and 1.6% had multiple types (n = 41). The most common HR-HPV types were 16, 56, 52 and 31 and LR-HPV 90 and 42. Of 187 HR-HPV infections detected (among 165 women), 55.1% (n = 103) were with HPV types not covered by available bivalent or quadrivalent HPV vaccines. About 23% (n = 43) were of types not covered by the nonavalent vaccine (HPV 35, 39, 51, 56, 59). The HR and LR-HPV prevalence were highest in the age group 30-34 years (HR 9.8%, 'moderate' risk 3.0% and LR 5.6%), decreasing with increasing age. HR-HPV prevalence in women with normal cytology was 5.5%. In women with a high-grade squamous intraepithelial lesion (HSIL), prevalence was 66.7%. Women currently not living with a partner and current smokers had increased chances of an HR-HPV infection. CONCLUSION: The overall population-based HPV prevalence was relatively high. An important share of prevalent HR-HPV infections constituted types not covered by current HPV vaccines. With the advent of HPV screening and younger vaccinated cohorts joining screening, HPV types should be monitored closely, also in older women who were not eligible for HPV vaccination.
