ABSTRACT Background HPV plays a key role in the development of cervical cancer. This study aims to investigate prevalence genotypes patients with Squamous cell carcinoma (SSC) and Adenocarcinoma (ADC) at NORI cancer Hospital Pakistan, aim improving screening prevention strategies. Method Cervical scrapings were collected from 129 diagnosed patients. typing was performed using real‐time PCR assay sequencing. Result Among patients, 73.6% (90/129) positive. Proportion positivity observed within each group. The highest incidence 50–60 years age group (80.9%), followed by 40‐to‐50‐year (75.8%). rate declined 60‐to‐70‐year‐old (63.6%) further 70–80 (62.5%). Eight different subtypes identified, 16 being most prevalent (80.0%), 18 (9.5%), 45 2 (2.1%), 31 1 (1.1%), 35 59 66 89 (1.15). Histologically, 89.2% cases (SCC) 10.8% Adenocarcinomas. In SCC found 80.9% cases, while detected 66.7% cases. Conclusion high‐risk types, both vaccine non‐vaccine, targeted Pakistan highlights urgent need for widespread vaccination programs. Tailored public health strategies are essential effectively reduce rates mortality.

The numerous high-risk carcinogenic types of human papillomavirus (HR-HPV) that lack vaccine protection underscore the urgent need to develop broader-spectrum HPV vaccines. This study addresses this by focusing on HR-HPV 53, 56, and 66, which are not currently targeted existing It introduces an effective method for their soluble expression, as well mutants, within Escherichia coli expression system. Through strategic homologous loop swapping among HPV53, HPV56, HPV66, we designed twenty double-type chimeric molecules. Comprehensive evaluations identified unique dominant immunogenic loops each type: FG HI DE with HPV66 emerging optimal backbone virus-like particle (VLP). By incorporating two immunodominant sites into preferable base particle, constructed a triple-type chimera H66-56HI-53FG, could efficiently self-assemble VLPs in vitro closely resembled wild-type VLP and, induced balanced neutralization titers (~ 3 log unites), contrast none observable HPV53 titer lower HPV56 elicited immunization alone. research outlines amenable way simultaneously identify context cross-type design, thereby offering paradigm extending antigenic variety single broaden coverage.

Abstract Introduction Human papillomavirus (HPV) presents a potential threat to the onset of carcinogenesis in cervix, anogenital regions, and oropharynx. HPV encompasses over 200 types, with at least 12 having cause cancer, impacting majority sexually active individuals. In this current research, we explore occurrence spread genotypes. Material methods During cross-sectional study conducted Sanandaj, Iran from Feb 2022 Aug 2023, diverse samples including oral, vaginal, genital were collected individuals referred private laboratories Iran. After sample collection DNA extraction (FAVORGEN, Taiwan), they subjected PCR genotyping (MehrViru, Iran). The subsequent statistical analysis unveiled infection rates across different demographics age groups. STATA (version 17) used for analysis. We examined using t-tests Odds Ratio. Results Overall, 26% (249) out 950 cases tested positive HPV, 69% these classified as high-risk. Among population, 98% (933) female, 2% (17) male. Females aged 31–40 exhibited highest percentage prevalence (115/460) belonging HR overall most frequent genotypes identified 6, 16, 52, 53, 51, 58, 56. HPV-16 frequency among genotypes, accounting 42 (17%) occurrences, followed by HPV-52 32 (13%). Conclusion Our findings emphasize significant females, particularly 21–30 group. identification high-risk underscores importance targeted interventions specific cohorts. age-stratified highlights consistent predominance groups, indicating need age-specific preventive measures. These results contribute valuable information designing effective screening vaccination strategies, alleviate impact diseases associated HPV.

Understanding the regional HPV genotype profile is critical for informing targeted vaccination strategies and optimizing cervical cancer screening programs to enhance their effectiveness. This study investigated prevalence distribution of human papillomavirus (HPV) genotypes among women with squamous cell carcinoma (CSCC) in Linyi city, China, from 2015 2023. Data were obtained 606 histologically diagnosed CSCC at Cancer Hospital between January December DNA was extracted paraffin-embedded tissue samples. genotyping performed via gene chip-based polymerase chain reaction (PCR) technology. Temporal trends age-specific variations analyzed provide a comprehensive epidemiological assessment. The overall infection 94.7% CSCC. 16 most prevalent (80.5%), followed by 18 (5.2%), 33 (2.8%), 31 (1.8%), 58 (1.8%). Single infections predominant (95.5%), while coinfections observed 4.5% cases. Age-specific analysis revealed that non-HPV more aged > 45 years, greater diversity older age groups. indicated decline younger patients (26-45 years), whereas significantly increased.

The prevalence distribution of HPV genotypes vary across regions lesion severity. Comprehensive data on genotype among Iranian women is limited. This study investigates the HR-HPV in abnormal cytology Qazvin province, northwest Iran, from 2007 2019.

Objective Cervical intraepithelial neoplasia grade 3 (CIN 3)-like SCC is a recently identified deceptive growth pattern that closely mimics endocervical crypt involvement by CIN 3. As 3-like indistinguishable from 3, it poses significant challenge for pathologists. Method We examined 23 cases of SCC, 6 which also had concomitant conventional invasive and 9 as control group. Immunohistochemistry was used to investigate the expression p16, E-cadherin, cyclin D1, p53, human papillomavirus (HPV) E6/E7 mRNA, key virus carcinogen HPV, detected.
