Review
Respiratory papilloma is a relatively common benign tumor of the respiratory tract, and a few patients may develop malignant changes. The disease has an insidious onset and lacks specific clinical manifestations, and its manifestations are closely related to the growth mode, location and size of the tumor. It can involve multiple parts, such as the larynx, trachea, bronchus, and lung parenchyma, which cause coughing, hoarseness, dysphonia, and, in severe cases, may lead to obstruction of the respiratory tract. At present, the treatment of respiratory papilloma lacks standardization, and there is no effective method to cure the disease. Surgery remains the main treatment for alleviating patients' symptoms and preventing airway obstruction. However, due to the high recurrence rate of respiratory papilloma, multiple surgeries are often needed, which reduces the quality of life of patients and increases their disease burden and economic burden. Bevacizumab, a vascular endothelial growth factor-binding antibody inhibitor, is a promising adjuvant treatment modality that shows good potential for reducing symptoms and the frequency of surgery. This article aimed to review the efficacy and safety of bevacizumab for the treatment of respiratory papilloma and discuss the differences and efficacy of the systemic application and intralesional injection of bevacizumab for the treatment of respiratory papilloma.

Review
OBJECTIVE
We conducted a systematic review to assess the scope and effectiveness of interventions to improve human papilloma virus (HPV) vaccination in Africa from 2006 to 2021.
STUDY DESIGN
Systematic review.
METHODS
Four databases (Medline, Embase, CINAHL and PsycINFO) were searched for articles published between 2006 and 2021. Articles were screened and included based on eligibility criteria using DistillerSR (Version 2.35). Data were extracted and reported using a narrative synthesis. A quality assessment was also conducted for each study using validated quality appraisal tools.
RESULTS
Out of 7603 articles identified by a systematic search, 18 articles met the inclusion criteria. Included studies comprised impact evaluation and cross-sectional studies published between 2012 and 2021 and conducted in eight African countries namely: Nigeria, Cameroon, South Africa, Kenya, Tanzania, Zambia, Mali, and Malawi. Study quality ranged from high to low quality. Interventions comprised fifteen educational and three multicomponent interventions. Out of thirteen impact evaluation studies (all educational interventions), twelve studies were effective in increasing HPV vaccine uptake and/or improving participants' knowledge, attitudes, and perceptions about the vaccine. Across five cross-sectional studies (two educational and three multicomponent interventions), HPV vaccine uptake rates ranged from 34% to 93.3%, with a consensus on safety and effectiveness in 67.9%-90.3% of participants post-intervention.
CONCLUSION
Educational and multicomponent interventions have been implemented to improve HPV vaccination in Africa. While educational interventions have proven effective at improving HPV vaccine uptake, a more diverse range of interventions with robust impact evaluation study designs are needed to strengthen the available evidence and improve vaccine uptake.

Objective To evaluate the value of SOX1 and PAX1 gene methylation detection in the secondary triage of high-grade cervical lesions.Methods Exfoliated cervical cells were collected from 122 patients tested positive for human papilloma virus (HPV) and subjected to thin-prep cytologic test (TCT) and SOX1/PAX1 gene methylation tests.Results The HPV test combined with TCT showed the sensitivity of 95.24% and the specificity of 23.75% for detecting cervical intraepithelial neoplasia (CIN) grade 2 and above (CIN2+).After the addition of the SOX1/PAX1 gene methylation detection in secondary triage,the sensitivity for detecting CIN2+ was 83.33%,which had no statistically significant difference from the sensitivity of TCT combined with HPV test (=0.078).However,the specificity reached 77.50%,which was significantly higher than that of HPV test combined with TCT (<0.001).The SOX1/PAX1 gene methylation level in the CIN2+ group was higher than those in the normal cervical tissue and the CIN1 group(<0.001).The cut-off values of SOX1 and PAX1 gene methylation for CIN2+ detection were -11.81 and -11.98,respectively.Conclusion Adding the detection of SOX1/PAX1 gene methylation in secondary triage significantly improves the efficiency and accuracy of CIN2+ detection.

Lacking of adequate knowledge is an obstacle to effective prevention of cervical cancer, yet factors that affect the information acquisition and seeking behavior as well as the information communication process are not well studied. We assessed information acquisition and seeking behavior, as well as perceived barriers of doctor-patient communication regarding human papilloma virus (HPV)-related information of infected women. Among 437 participants, 405 (93%) expressed demands for HPV-related information, while only a small proportion (100/437, 22.9%) actively sought information and felt obstacles comprehending. Web-based channels were most frequently utilized and medical personnel were the most trusted information source. Patients' satisfaction was significantly correlated with doctor's patience ( = 0.581, < 0.001) and emotional caring ( = 0.555, < 0.001). Compared to patients not actively seeking information, those actively seeking information were more likely to be single ( = 0.005), had higher education ( = 0.009) and monthly individual-level income ( = 0.023), and was more likely to undergo regular cervical cancer screening ( = 0.003), and were already or willing to be vaccinated ( = 0.008). The actively seeking information group also achieved higher scores in HPV knowledge test ( = 0.007). Public health interventions targeting HPV-infected women using specifically designed educational materials may influence information seeking behavior, increase HPV literacy and knowledge, which could potentially increase HPV vaccine uptake and cervical cancer screening rate.

Cervical cancer (CC) is the fourth most common cancer among female patients. The primary cause of all types of cervical cancer is human papillomavirus (HPV), which was projected to account for 5,70,000 reported cases in 2018. Two HPV strains (16 and 18) account for 70% of cervical abnormalities and precancerous cervical cancers. CC is one of the main causes of the 17% cancer-related death rate among Indian women between the ages of 30 and 69 is CC. The side effects of the currently approved treatments for cervical cancer could endanger the lives of women affected by the illness. Thus, probiotics may be extremely important in the management of CC. Numerous studies on probiotics and their potential for use in cancer diagnosis, prevention, and treatment have been conducted. This review describes the enhancement of the immune system, promotion of a balanced vaginal microbiome, and decreased risk of secondary infections, which have anti-inflammatory effects on the body. Probiotics have the potential to reduce inflammation, thereby adversely affecting cancer cell growth and metastasis. During the course of antibiotic therapy, they support a balanced vaginal microbiome. Oncogenic virus inactivation is possible with probiotic strains. In postmenopausal women, the use of vaginal probiotics helps lessen menopausal symptoms caused by Genitourinary Syndrome of Menopause (GSM). The antitumor effects of other medications can be enhanced by them as potential agents, because they can both promote the growth of beneficial bacteria and reduce the quantity of potentially harmful bacteria. The development of tumors and the proliferation of cancer cells may be indirectly affected by the restoration of the microbial balance. Probiotics may be able to prevent and treat cervical cancer, as they seem to have anticancer properties. To identify probiotics with anticancer qualities that can supplement and possibly even replace traditional cancer treatments, further investigation is required, including carefully planned clinical trials.

Organized cervical screening programmes are commonplace in high-income countries. To provide an equitable cervical screening service, it is important to understand who is and is not attending screening and why. Promotion of screening and service improvement is not possible without recognition and identification of the barriers and needs of communities that are less engaged with screening. This study explored stakeholder perceptions of cervical screening attendance and accessibility in Ireland. Semi-structured interviews were conducted with 12 healthcare professionals, policymakers and academics. Interviews were conducted online in 2022. Reflexive thematic analysis was used inductively to generate themes, supported by NVivo. Three themes were developed: (i) getting the right information out the right way, (ii) acceptability and accessibility of screening and (iii) trying to identify and reach the non-attenders. Participants felt public knowledge of cervical screening and human papilloma virus was low and communication strategies were not adequate. Individual, cultural, structural and service-level factors influenced the accessibility and acceptability of screening. Identifying and reaching non-attenders was considered challenging and community outreach could support those less likely to attend screening. Stakeholder perspectives were valuable in understanding the complexities of screening accessibility and attendance from individual to service-level factors. Cultural competency training, inclusive language and visual cues in waiting rooms would support engagement with some populations who may be hesitant to attend screening. Collaboration with community organizations has opportunities to promote screening and understand the needs of those less likely to attend screening.

Head and neck squamous cell carcinoma (HNSCC) is one of the most common tumor entities worldwide, with human papillomavirus (HPV) infection contributing to cancer development. Conventional therapies achieve only limited efficiency, especially in recurrent or metastatic HNSCC. As the immune landscape decisively impacts the survival of patients and treatment efficacy, this study comprehensively investigated the immunological tumor microenvironment (TME) and its association with patient outcome, with special focus on several dendritic cell (DC) and T lymphocyte subpopulations. Therefore, formalin-fixed paraffin-embedded tumor samples of 56 HNSCC patients, who have undergone resection and adjuvant radiotherapy, were analyzed by multiplex immunohistochemistry focusing on the detailed phenotypic characterization and spatial distribution of DCs, CD8 T cells, and T-helper cell subsets in different tumor compartments. Immune cell densities and proportions were correlated with clinical characteristics of the whole HNSCC cohort and different HPV- or hypoxia-associated subcohorts. Tumor stroma was highly infiltrated by plasmacytoid DCs and T lymphocytes. Among the T-helper cells and CD8 T cells, stromal regulatory T cells and intraepithelial exhausted CD8 T cells expressing programmed cell death protein-1 (PD-1) and/or lymphocyte-activation gene-3 (LAG-3) were the predominant phenotypes, indicating an immunosuppressive TME. HPV-associated tumors showed significantly higher infiltration of type I and type II conventional DCs (cDC1, cDC2) as well as several CD8 T cell phenotypes including exhausted, activated, and proliferating T cells. On the contrary, tumors with hypoxia-associated gene signatures exhibited reduced infiltration for these immune cells. By multivariate Cox regression, immune-related prognostic factors were identified. Patient clusters defined by high infiltration of DCs and T lymphocytes combined with HPV positivity or low hypoxia showed significantly prolonged survival. Thereby, cDC1 and CD8 T cells emerged as independent prognostic factors for local and distant recurrence. These results might contribute to the implementation of an immune cell infiltration score predicting HNSCC patients' survival and such patient stratification might improve the design of future individualized radiochemo-(immuno)therapies.
