    必须更彻底地解决其医疗保健需求的拉丁美洲人的一个子群体是在美国(U.S.)从事季节性农业工作的大约300万农场工人。拉丁裔移民和季节性农场工人(MSFW)面临复杂的政治问题,社会,以及使医疗服务复杂化的个人环境。尽管人乳头瘤病毒(HPV)疫苗可以预防HPV感染和癌症,西班牙裔青少年的摄取仍然欠佳。因此,了解拉丁裔MSFW的HPV知识很重要,以及疫苗接种的障碍和促进者,因此文化上适当的措施可以加强疫苗接种。在PubMed进行了综合审查,Scopus,和WebofScience使用关键搜索词。评估结果是否符合纳入/排除标准,并通过主题分析对选定的文章进行编码和评估。六项各种设计的研究最终被纳入审查。虽然一些拉丁裔MSFW对HPV和疫苗有基线知识,知识差距依然存在。参与者对疫苗的工作原理表示好奇,内容,副作用,给药,推荐年龄,以及预防疾病的信息。尽管额外的教育和MSFW对提供者建议的接受度被认为是主要的促进者,许多障碍也需要解决。提供商必须利用MSFW的现有知识,提供教育,并促进疫苗接种,以保护农场工人家庭免受HPV和相关癌症的侵害。提供者向MSFW推荐HPV疫苗必须成为标准做法,接受这次谈话的人。增加疫苗接种可以减少HPV相关癌症对患者的不成比例的负担,并促进获得医疗保健服务。
    One subgroup of Latinos whose healthcare needs must be more thoroughly addressed is the roughly three million farmworkers pursuing seasonal agricultural work within the United States (U.S.). Latino migrant and seasonal farmworkers (MSFW) face compounded political, social, and personal contexts that complicate healthcare access. Although the human papillomavirus (HPV) vaccine prevents HPV infections and cancers, uptake among Hispanic adolescents remains suboptimal. Therefore, it is important to understand Latino MSFW\'s HPV knowledge, as well as barriers to and facilitators of vaccination so culturally appropriate measures can bolster vaccination. An integrative review was conducted in PubMed, Scopus, and Web of Science using key search terms. Results were evaluated for compatibility with inclusion/exclusion criteria, and selected articles were coded and evaluated via thematic analysis. Six studies of various designs were ultimately included in the review. While some Latino MSFW have baseline knowledge about HPV and the vaccine, knowledge gaps remain. Participants expressed curiosity about how the vaccine works, contents, side effects, dosing, recommended age, and information about prevented diseases. Although additional education and MSFW\'s receptiveness to provider\'s recommendations were cited as major facilitators, many barriers also need addressed. Providers must leverage MSFW\'s existing knowledge, provide education, and facilitate vaccination to protect farmworker families from HPV and related cancers. It must become standard practice for providers to recommend the HPV vaccine to MSFW, who are receptive to this conversation. Increasing vaccination can decrease the disproportionate burden of HPV-related cancers on patients and facilitate access to healthcare services.

    背景:异常DNA甲基化是癌症中常见的表观遗传修饰,包括口咽鳞癌(OPSCC)和口腔鳞癌(OSCC)。因此,甲基化水平的分析似乎对改善癌症治疗和预后是必要的.
    方法:酶联免疫吸附测定(ELISA)用于分析OPSCC和OSCC肿瘤以及DNA分离后边缘样品中的整体DNA甲基化水平。使用GenoFlowHPV阵列测试试剂盒(DiagCorBioscienceInc.,香港,中国)。使用实时PCR和EBVPCR试剂盒(EBV/ISEX/100,GeneProof,布尔诺,捷克共和国)。
    结果:从女性获得的OPSCC肿瘤样本显示整体DNA甲基化水平低于男性(1.3%vs.3.5%,p=0.049)。HPV和EBV共感染的OPSCC患者的边缘样本显示整体DNA甲基化低于未共感染的患者(p=0.042)。OSCC患者的G3肿瘤的整体DNA甲基化水平明显低于G2肿瘤(0.98%±0.74%vs.3.77%±4.97%,p=0.010)。此外,HPV阳性OSCC患者的肿瘤总体DNA甲基化水平明显低于HPV阴性患者(p=0.013)。在边距样本中,我们观察到总体DNA甲基化与OSCC患者的N分期之间存在显着负相关(rS=-0.33,p=0.039)。HPV阳性OPSCC患者的整体DNA甲基化水平高于HPV阳性OSCC患者(p=0.015)。
    结论:我们证实甲基化可能与病毒因子有关,如HPV和EBV,以及临床和人口统计学参数。
    BACKGROUND: Aberrant DNA methylation is a common epigenetic modification in cancers, including oropharyngeal squamous cell carcinoma (OPSCC) and oral squamous cell carcinoma (OSCC). Therefore, the analysis of methylation levels appears necessary to improve cancer therapy and prognosis.
    METHODS: The enzyme-linked immunosorbent assay (ELISA) was used to analyse global DNA methylation levels in OPSCC and OSCC tumours and the margin samples after DNA isolation. HPV detection was conducted by hybridisation using GenoFlow HPV Array Test Kits (DiagCor Bioscience Inc., Hong Kong, China). EBV detection was performed using real-time PCR with an EBV PCR Kit (EBV/ISEX/100, GeneProof, Brno, Czech Republic).
    RESULTS: OPSCC tumour samples obtained from women showed lower global DNA methylation levels than those from men (1.3% vs. 3.5%, p = 0.049). The margin samples from OPSCC patients with HPV and EBV coinfection showed global DNA methylation lower than those without coinfection (p = 0.042). G3 tumours from OSCC patients had significantly lower levels of global DNA methylation than G2 tumours (0.98% ± 0.74% vs. 3.77% ± 4.97%, p = 0.010). Additionally, tumours from HPV-positive OSCC patients had significantly lower global DNA methylation levels than those from HPV-negative patients (p = 0.013). In the margin samples, we observed a significant negative correlation between global DNA methylation and the N stage of OSCC patients (rS = -0.33, p = 0.039). HPV-positive OPSCC patients had higher global DNA methylation levels than HPV-positive OSCC patients (p = 0.015).
    CONCLUSIONS: We confirmed that methylation could be changed in relation to viral factors, such as HPV and EBV, as well as clinical and demographical parameters.

    目的:宫颈锥切术是治疗癌前病变的有效方法。然而,在手术标本中没有发现高级别病变的情况下,由于缺乏针对阴性锥形连接的既定随访方案,因此管理这些患者可能具有挑战性.本研究旨在通过组织病理学回顾评估我们机构的阴性锥化率,识别诊断错误,可能的风险和复发因素,并提出对该组患者的随访策略。
    方法:2010年1月至2020年12月的一项回顾性研究分析了锥形锥切术阴性的患者,包括所有手术技术和手术指征。回顾了活检和宫颈锥形切片,对结果阴性的患者进行了更深层次的石蜡块切片,并应用了免疫组织化学染色:p16,Ki-67和geminin。将数据与由29名使用CIN3的女性组成的对照组进行比较。
    结果:在1022个conizations中,186个为阴性(18.1%),在排除35例患者后,选择151例用于研究。病理检查后,4例患者因宫颈活检结果假阳性而被排除,16用于假阴性锥化结果,9用于深切片后发现的隐性发育不良。其余122例患者被认为是真正的阴性视锥细胞(11.9%),并且在20.4%的病例中表现出p16阳性的IHC染色,Ki-67低表达,和低Geminin分数在大多数情况下。CIN1标本p16染色患病率较高,Ki-67表达和geminin评分与无肿瘤相比,然而,geminin没有统计学差异。年纪大了,p16阴性、Ki-67和geminin表达较高的产次和IHC模式被确定为阴性视锥细胞的危险因素(p<0.05)。只有10名患者因高级别病变复发,没有发现统计学上显著的危险因素。
    结论:锥化阴性率为11.9%,通过手术前活检发现的诊断错误,锥形试样,更深层次。危险因素包括年龄较大,更高的奇偶校验,p16、Ki-67和geminin的低表达(p<0.05)。复发占负锥体的8.1%,没有识别统计学上显著的危险因素。对于锥化阴性的患者,建议进行更深层次的病理检查和2年的随访。
    OBJECTIVE: Cervical conization is an effective treatment for precancerous lesions. However, in cases where no high-grade lesion is identified in the surgical specimen, managing these patients may be challenging due to the absence of established follow-up protocols for negative conizations. This study aimed to assess the negative conization rates at our institution by histopathological review, identify diagnostic errors, possible risk and recurrence factors and propose follow-up strategies for this group of patients.
    METHODS: A retrospective study from January-2010 to December-2020 analyzed patients with negative conization including all surgical techniques and procedure indications. Biopsy and cervical conizations slides were reviewed and patients who kept a negative result underwent deeper levels sectioning of the paraffin blocks with immunohistochemical stains application: p16, Ki-67 and geminin. Data were compared with a control group composed by 29 women with CIN3.
    RESULTS: Out of 1022 conizations, 186 were negative (18.1%), with 151 cases selected for the study after excluding 35 patients. Following pathology review, 4 patients were excluded due to false-positive cervical biopsy results, 16 for false-negative conization results and 9 for hidden dysplasia identified after deeper sectioning. The remaining 122 patients were considered truly negative cones (11.9%) and exhibited IHC staining with p16 positive in 20.4% of cases, low Ki-67 expression, and low geminin score in most cases. Specimens with CIN 1 had higher prevalence of p16 staining, Ki-67 expression and geminin score when compared to absence of neoplasia, nevertheless geminin had no statistical difference. Older age, higher parity and IHC pattern with negative p16, low Ki-67 and geminin expressions were identified as risk factors for negative cones (p<0.05). Only 10 patients recurred for high-grade lesions, with no statistically significant risk factors identified.
    CONCLUSIONS: The negative conization rate was 11.9%, with diagnostic errors identified across pre-surgical biopsy, cone specimen, and deeper levels. Risk factors included older age, higher parity, low expression of p16, Ki-67 and geminin (p<0.05). Recurrence represented 8.1% of the negative cones, without identification of statistically significant risk factors. Pathological review with deeper level sections and 2-year follow-up are recommended for patients with negative conizations.

    背景:宫颈癌是乌干达的主要公共卫生问题,由于筛查有限,特别是在农村地区,发病率很高。2019年,使用GeneXpert进行HPVDNA检测,以改善筛查。评估自引入以来的进展和挑战很重要。
    目的:确定基因型分布并探索在乌干达使用GeneXpert进行HPV筛查的卫生工作者经验。
    方法:我们进行了一项回顾性队列研究,分析了2021年3月至2023年5月全国66个GeneXpert实验室的HPV筛查数据。我们使用描述性统计数据从数据中提供百分比和比例。与卫生工作者进行了七次焦点小组讨论和五次访谈,以了解经验。
    结果:我们提取了24,497个HPV检测,39.1%为HPV阳性。其他高危HPV基因型最常见,占65%。其次是HPV16(17%)和HPV18/45(18%)。15%的HPV阳性病例有一个以上的基因型。定性结果显示卫生工作者知识不一致,高工作量,和复杂的护理寻求行为是主要挑战。它还显示了社区意识低,寻求传统治疗师的护理,结论:HPVDNA检测自推出以来一直在扩大,但是HPV病例的产量低于预期,信号需要解决供应方的挑战。卫生工作者,特别是社区卫生工作者中关于HPV的信息有限,像神话一样的需求方障碍,还必须通过培训卫生工作者和参与社区的提高认识运动来解决医疗多元化和社会规范问题。尽管使用GeneXpert服务的机会有所增加,卫生系统的弱点是HPV筛查的瓶颈。需要有针对性的干预措施来加强HPV诊断,预防宫颈癌,挽救生命。
    BACKGROUND: Cervical cancer is a major public health issue in Uganda, with high incidence due to limited screening especially in rural areas. In 2019, HPV DNA testing using GeneXpert was rolled out to improve screening access. Assessing progress and challenges since its introduction is important.
    OBJECTIVE: To determine genotype distribution and explore health worker experiences with HPV screening using GeneXpert in Uganda.
    METHODS: We conducted a retrospective cohort study where HPV screening data from 66 GeneXpert labs from March 2021-May 2023 country wide was analyzed. We used descriptive statistics to provide percentages and proportions from the data. Seven focus group discussions and five interviews were done with health workers to understand experiences.
    RESULTS: We extracted 24,497 HPV tests that were done, and 39.1% were HPV positive. Other high-risk HPV genotypes were the most common at 65%, followed by HPV 16 (17%) and HPV 18/45 (18%). 15% of the HPV positive cases had more than one genotype. Qualitative findings showed inconsistent health worker knowledge, high workload, and complex care seeking behaviors as main challenges. It also revealed low community awareness, care seeking from traditional healers, CONCLUSION: HPV DNA testing has been expanding since its rollout, but the yield of HPV cases is lower than expected, signaling need to address supply-side challenges. Limited information on HPV among health workers especially community health workers, demand-side barriers like myths, medical pluralism and social norms must also be tackled through trainings of health workers and awareness campaigns engaging communities. Although access to GeneXpert services has increased, health system weaknesses pose bottlenecks to screening HPV. Targeted interventions are required to strengthen HPV diagnosis, prevent cervical cancer and save lives.

    头颈癌(HNC)是世界上第六大最常见的癌症,在年轻人群中,与人乳头瘤病毒(HPV)相关的HNC尤其增加。历史上,这种疾病的标准治疗包括联合手术和放疗或基于铂的治愈性同步放化疗,具有相关的长期和晚期毒性。然而,HPV阳性HNC被认为是一种独特的癌症亚型,通常具有改善的临床结果。因此,已经广泛研究了治疗降级策略,以减轻与当前护理标准相关的不良反应,同时不影响疗效.这些策略包括治疗降级,例如新颖的手术技术,替代辐射技术,辐射剂量和体积减少,以及新辅助化疗,免疫疗法,和联合疗法。尽管这些疗法显示出巨大的希望,由于对其广泛实施的犹豫,其中许多仍在调查中。这篇综述的目的是总结针对HPV阳性HNC设计的降阶梯策略和新辅助疗法的最新进展。虽然具体的治疗方法在被广泛采用之前可能需要额外的研究,最近研究的令人鼓舞的结果突出了新辅助化疗和免疫治疗的优势,以及在管理HPV阳性HNC中的放射和手术降级方法。
    Head and neck cancer (HNC) is the 6th most common cancer across the world, with a particular increase in HNC associated with human papilloma virus (HPV) among younger populations. Historically, the standard treatment for this disease consisted of combined surgery and radiotherapy or curative platinum-based concurrent chemoradiotherapy, with associated long term and late toxicities. However, HPV-positive HNC is recognized as a unique cancer subtype, typically with improved clinical outcomes. As such, treatment de-escalation strategies have been widely researched to mitigate the adverse effects associated with the current standard of care without compromising efficacy. These strategies include treatment de-escalation, such as novel surgical techniques, alternative radiation technologies, radiation dose and volume reduction, as well as neoadjuvant chemotherapies, immunotherapies, and combined therapies. Although these therapies show great promise, many of them are still under investigation due to hesitation surrounding their widespread implementation. The objective of this review is to summarize the most recent progress in de-escalation strategies and neoadjuvant therapies designed for HPV-positive HNC. While specific treatments may require additional research before being widely adopted, encouraging results from recent studies have highlighted the advantages of neoadjuvant chemotherapy and immunotherapy, as well as radiation and surgical de-escalation approaches in managing HPV-positive HNC.

    背景:人乳头瘤病毒(HPV)与世界范围内的宫颈癌和宫颈异型增生有关。一个地区的HPV患病率数据很重要,因为它可以预测该特定地区的人群患宫颈癌的可能性。此外,随着有效疫苗的出现,公共卫生系统必须意识到HPV的优势才能实施疫苗.本研究旨在了解南安达曼岛妇女中HPV的患病率及相关因素。
    方法:从2018年至2022年,在南安达曼区的育龄(18-59岁)已婚妇女中进行了横断面研究。在获得HPV分子检测(HPVDNA)如PCR测定的知情书面同意后,从参与者收集宫颈擦伤。使用标准问卷收集人口统计数据,并进行统计分析以确定相关因素。
    结果:研究显示HPV的患病率为5.9%(95%CI:3.9-7.9),HR-HPV16的患病率为4.1%(95%CI2.6-5.5),HR-HPV18的患病率为1.8(95%CI:0.6-3)。与HPV阳性相关的独立因素是年龄在55岁以上,更年期,绝经后出血,血染色的阴道分泌物和体重减轻。年龄与南安达曼妇女的所有HPV感染有关。
    结论:据报道,HPV16是南安达曼妇女中主要的高危HPV类型。宫颈癌和癌前病变与HPV阳性和高危型HPV16显著相关。基于与HPV相关的危险因素的知识,在这个偏远岛屿的妇女中,实施更强的公共卫生意识和预防性HPV疫苗接种至关重要。
    BACKGROUND: Human papillomavirus (HPV) is associated with cervical cancer and cervical dysplasia worldwide. Data on HPV prevalence in a region is important because it serves as a predictor of the likelihood of the population in that particular region acquiring cervical cancer. Moreover, with the availability of effective vaccines, the public health system must be aware of the preponderance of HPV to implement the vaccine. The present study was designed to understand the prevalence of HPV and associated factors among the women of South Andaman Island.
    METHODS: A cross-sectional study was conducted among married women of reproductive age (18-59 years) from South Andaman District from 2018 to 2022. Cervical scrapes were collected from participants after obtaining informed written consent for HPV molecular testing (HPV DNA) such as PCR assay. Demographic data was collected using a standard questionnaire and statistical analyses were performed to determine the associated factors.
    RESULTS: The study showed prevalence of HPV as 5.9%(95% CI: 3.9-7.9) and prevalence of HR-HPV16 was 4.1% (95% CI 2.6 - 5.5) and HR-HPV18 prevalence was 1.8(95% CI: 0.6-3). The independent factors associated the HPV positivity were age above 55 years, menopause, post-menopausal bleeding, blood-stained vaginal discharge and loss of weight. Age was associated with all HPV infections among the South Andaman women.
    CONCLUSIONS: HPV 16 was reported as the predominant high risk HPV type circulating among women of South Andaman. Cervical cancer and precancerous lesions were significantly associated with HPV positivity and High risk HPV 16. Based on the knowledge of the risk factors associated with HPV, implementation of stronger public health awareness and prophylactic HPV vaccination is crucial among the women of this remote island.

    背景:人乳头瘤病毒(HPV)感染和宫颈尖锐湿疣(CA)经常共存。虽然治疗宫颈CA的方法很多,高复发率和宫颈疤痕仍然很麻烦。活检钳切除联合5-氨基酮戊酸光动力疗法(ALA-PDT)是治疗宫颈CA的可行方法,但其疗效和局限性有待评估。
    方法:这项回顾性研究包括49例年龄在18-50岁之间的患者,这些患者经组织学或阴道镜证实为宫颈CA和HPV感染。患者接受活检钳切除和ALA-PDT治疗。通过HPV分型和阴道镜引导活检评价疗效。
    结果:联合治疗3个月后,病灶总缓解率为93.88%(46/49),HPV清除率为83.67%(41/49)。一名患者显示一些残留病变,两名患者显示新病变。随访6个月复发率为4.34%。随访3、6个月时HPV清除率差异无统计学意义。单变量分析显示,对于可见病灶大小>1.5cm2的患者,联合治疗效果较差。不良反应很小,没有结构性并发症的报道。主要副作用为腹痛和阴道分泌物增多。
    结论:活检钳切除联合ALA-PDT对消除宫颈尖锐湿疣病变和根除HPV感染是安全有效的。建议在治疗前后进行阴道镜检查。
    BACKGROUND: Human papilloma virus (HPV) infection and cervical condyloma acuminatum (CA) often co-exist. Although there are many methods to treat cervical CA, high recurrence rate and cervical scars are still troublesome. Biopsy forceps excision combined with 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a feasible approach for cervical CA, but its efficacy and limitation need to be evaluated.
    METHODS: This retrospective study consisted of 49 patients aged 18-50 years with a histologically or colposcopic confirmed cervical CA and with HPV infection. Patients were treated with biopsy forceps excision and ALA-PDT. The efficacy was evaluated through HPV typing and colposcopy directed biopsy.
    RESULTS: Three months after the combination treatment the total lesion remission rate was 93.88 % (46/49) and the HPV clearance rate was 83.67 % (41/49). One patients showed some residual lesions and two patients showed new lesions. Recurrence rate was 4.34 % at 6 months follow-up. There was no significant difference in HPV clearance rate at 3 and 6 months follow-up. Univariate analysis showed that the combination treatment was less effective for patients who had size of visible lesion > 1.5 cm2. Adverse effects were minimal and no structural complications were reported. The main side effects were abdominal pain and increased vaginal secretions.
    CONCLUSIONS: Combination of biopsy forceps excision and ALA-PDT is safe and effective for eliminating cervical condylomata lesion and eradicating HPV infection. Colposcopic evaluation is recommended before and after treatment.

    非小细胞肺癌(NSCLC)是全球癌症相关死亡率的主要原因。值得注意的是,肺癌在不吸烟者中的发病率,主要是女性,近年来一直在上升。在各种相关风险因素中,人乳头瘤病毒(HPV)可能在某些亚组患者的NSCLC发展中起作用。人类肿瘤肺细胞中高危HPV-DNA的流行率在世界范围内各不相同;然而,HPV在NSCLC中的致癌作用尚未完全了解.血流可能是从感染部位到肺部的传播途径之一,以及口服(通过无保护的口交)和空气传播。以前的研究报道,在患有HPV相关肿瘤的患者中,NSCLC的风险升高。如宫颈,喉,或口咽癌,与阴性形式相比,HPV阳性肺癌的预后更好。另一方面,16%的NSCLC患者在外周血中呈现循环HPV-DNA以及miRNA表达。通常,这些患者有低分化的NSCLC,经常在晚期被诊断。然而,HPV阳性肺癌似乎对靶向治疗(EGFR)和免疫检查点抑制剂有更好的反应,并显示出对铂类治疗的敏感性增加。这篇综述总结了目前关于HPV在NSCLC发展中的作用的证据。特别是在有HPV相关癌症病史的患者中。它还检查了HPV的诊断和预后意义,调查新的未来观点,以加强癌症筛查,诊断方案,以及针对确诊HPV感染的非小细胞肺癌患者的特定队列,开发更有针对性的治疗方法。
    Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Notably, the incidence of lung cancer among never-smokers, predominantly women, has been rising in recent years. Among the various implicated risk factors, human papilloma virus (HPV) may play a role in the development of NSCLC in a certain subset of patients. The prevalence of high-risk HPV-DNA within human neoplastic lung cells varies across the world; however, the carcinogenetic role of HPV in NSCLC has not been completely understood. Bloodstream could be one of the routes of transmission from infected sites to the lungs, along with oral (through unprotected oral sex) and airborne transmission. Previous studies reported an elevated risk of NSCLC in patients with prior HPV-related tumors, such as cervical, laryngeal, or oropharyngeal cancer, with better prognosis for HPV-positive lung cancers compared to negative forms. On the other hand, 16% of NSCLC patients present circulating HPV-DNA in peripheral blood along with miRNAs expression. Typically, these patients have a poorly differentiated NSCLC, often diagnosed at an advanced stage. However, HPV-positive lung cancers seem to have a better response to target therapies (EGFR) and immune checkpoint inhibitors and show an increased sensitivity to platinum-based treatments. This review summarizes the current evidence regarding the role of HPV in NSCLC development, especially among patients with a history of HPV-related cancers. It also examines the diagnostic and prognostic significance of HPV, investigating new future perspectives to enhance cancer screening, diagnostic protocols, and the development of more targeted therapies tailored to specific cohorts of NSCLC patients with confirmed HPV infection.

    Cervical cancer remains a critical challenge in reproductive health worldwide, with especially high burden in Africa. A recent publication in the Lancet reported 604,127 cases of cervical cancer worldwide in 20201, of which 117,316 cases (19.4%) were in the five African regions. East Africa had the highest incidence rate followed by West Africa, while north and South Africa had the lowest rates. Similarly, the highest cervical cancer mortality rate worldwide, 28.6 deaths per 100,000 women years, was reported from East Africa, and was followed by South Africa.

    超过95%的成年人群携带致癌和持久性爱泼斯坦巴尔病毒(EBV)。虽然大多数无症状,EBV可引起多种淋巴或上皮细胞起源的恶性肿瘤。其中一些还与共同感染有关,这些共同感染会增加EBV诱导的肿瘤发生或削弱其免疫控制。各自的病原体包括卡波西肉瘤相关疱疹病毒(KSHV),恶性疟原虫和人类免疫缺陷病毒(HIV)。在这次审查中,我将讨论各自的肿瘤实体和共同感染增加EBV相关癌症负担的可能机制。对潜在机制的更好理解可以使我们识别EBV相关恶性肿瘤的关键特征及其免疫控制缺陷。然后可以探索这些以通过靶向EBV和/或与病原体特异性疗法或疫苗接种的相应共感染来开发针对相应癌症的疗法。
    The oncogenic and persistent Epstein Barr virus (EBV) is carried by more than 95% of the human adult population. While asymptomatic in most of these, EBV can cause a wide variety of malignancies of lymphoid or epithelial cell origin. Some of these are also associated with co-infections that either increase EBV-induced tumorigenesis or weaken its immune control. The respective pathogens include Kaposi-sarcoma-associated herpesvirus (KSHV), Plasmodium falciparum and human immunodeficiency virus (HIV). In this review, I will discuss the respective tumor entities and possible mechanisms by which co-infections increase the EBV-associated cancer burden. A better understanding of the underlying mechanisms could allow us to identify crucial features of EBV-associated malignancies and defects in their immune control. These could then be explored to develop therapies against the respective cancers by targeting EBV and/or the respective co-infections with pathogen-specific therapies or vaccinations.
