肿瘤的形成可由多种病毒引起[1],其一就是人类乳头状瘤病毒(Human papillomavirus,HPV).HPV是1949年从普通疣体浸出液中首次被观察到,1995年有研究证实HPV感染为宫颈癌的致病病原体.研究显示:HPV16、18能促使人类鳞状上皮的增生.目前HPV16、18变异体的致瘤性受到各国学者的广泛关注.  相似文献

人乳头瘤病毒 (HPV) ,尤其是HPV1 6型 ,是子宫颈癌的主要病原体。因此 ,通过引起病人适当的病毒特异性免疫反应可以预防或治疗HPV相关的子宫颈恶性肿瘤。在已经进行预防接种的个体中 ,包括L1和L2在内的HPV衣壳蛋白已经显示出能够产生对抗HPV颗粒抗体的抑制。此外 ,HPV致瘤性蛋白 ,例如E6蛋白和E7蛋白 ,在细胞转换的导入和维持方面是很重要的 ,在大多数包含HPV的癌症中它们也是共同表达的。它们为产生抗HPV感染和HPV相关肿瘤形成的治疗量的疫苗提供了理想的靶。针对这些蛋白的疫苗可能提供一个控制HPV相关恶性肿瘤的机会。拥有…  相似文献

目的 了解不同亚型的人乳头状瘤病毒(human papillomavirus,HPV)在鼻内翻性乳头状瘤(nasal inverted papilloma,NIP)中的分布,探讨其在NIP发病中的作用.方法 将78例NIP腊包埋组织标本分为单纯NIP组、伴不典型增生NIP组和NIP癌变组,同时选取40例健康体检者鼻腔粘膜组织作为健康对照组,采用聚合酶链反应(PCR)技术检测HPV6、11、16及18型感染情况.结果 78例NIP石蜡包埋组织标本HPV总阳性率为61.5%.单纯NIP组、伴不典型增生NIP组和NIP癌变组阳性率分别达59.5%、73.9%和46.2%.随着NIP临床分期级别的升高,HPV感染率也呈相应的上升趋势.单纯NIP组以低危型HPV6、11型感染为主,NIP癌变组则同时检出高危型HPV16型和HPV18型.结论 HPV感染在NIP发病中起着重要作用,其中高危型HPV感染能扩大NIP病变范围,而HPV16、18型可能与NIP恶变有关联.  相似文献

ObjectiveRising incidence of HPV-positive head and neck cancers (HPV-HNC) means HPVinfection is increasingly relevant to patient-provider consultations. We performed a systematic review to examine, in the context of patient-provider HNC consultations: discussions about HPV, attitudes towards discussing HPV and information needs.MethodsWe searched Embase, PsychINFO, and CINAHL + for studies to August 2018. Eligible studies included: HNC healthcare professionals (HCPs) and/or HNC patients investigated HNC patient-provider communication about HPV.ResultsTen studies were identified: six including HCPs and four including HNC patients. HCPs varied in confidence in HPV discussions, which was related to their HPV knowledge. Both HCPs and patients acknowledged the need for reliable HPV information. Factors which facilitated HPV discussions included accessible HPV information for patients and HCPs and good HPV knowledge among HCPs. Barriers included the perception, among HCPs, that HPV was a challenging topic to discuss with patients.ConclusionsInformation deficits, communication challenges and barriers to discussing HPV were identified in HNC patient-provider consultations.Practice implicationsAppropriate HPV information is needed for HCPs and patients. Professional development initiatives which increase HCPs’ HPV knowledge and build their communication skills would be valuable.  相似文献

The subcellular localization of WT1 is controversial and has received little attention in the epithelial tumors of salivary glands. Paraffin-embedded, surgical specimens from 80 salivary tumors were investigated by immunohistochemistry using a monoclonal, anti-WT1 antibody (6F-H2, Dako). Immunostaining was seen in 14/14 pleomorphic adenomas (PAs), 6/6 myoepitheliomas, 4/4 basal cell adenomas, 4/4 canalicular adenomas, 0/7 Warthin tumors, 0/1 oncocytoma, 1/6 acinic cell carcinomas (Cas), 0/11 mucoepidemoid Cas, 1/11 adenoid cystic Cas, 11/12 polymorphous low-grade adenocarcinomas (PLGAs), 1/2 Ca ex PA, 0/1 salivary duct Ca and 0/1 clear cell adenocarcinoma. Stained-cell subpopulations up to 90% were not uncommon in the benign tumors. Up to 80% of cells in PLGA could be stained. Staining was weak to intense and confined to the cytoplasm of preferentially non-luminal or adjacent to stroma cells. One adenoid cystic Ca showed nuclear staining. The results suggest that WT1 is often highly expressed in benign non-oncocytic salivary tumors whereas the malignant tumors show decreased expression, the exception being PLGA. The expression is usually cytoplasmic and associated with non-luminal cells. PLGA immunoreactivities could be useful in histological differential diagnosis.  相似文献

Summary Immunohistochemical identification of human epidermal growth factor (hEGF) was carried out in a total of 152 cases of salivary gland tumours, consisting 107 pleomorphic adenomas and their variants, 13 adenolymphomas and 32 adenoid cystic carcinomas. A high percentage of pleomorphic adenomas revealed markedly positive hEGF staining of the luminal surface cells of tubuloductal structures and of modified or neoplastic myoepithelial cells. Clear cells of the tumour showed various reactivities from very slight to strong. Eosinophilic epithelial cells of adenolymphoma gave a positive reaction for hEGF in all the cases, whereas most adenoid cystic adenoma lacked hEGF staining; however some cases showed positive staining of the tumour cells. The immunohistochemical detection of hEGF in most salivary gland tumours suggests this factor to be a possible new marker of salivary glands tumours, and to have a biological role in tumour proliferation.  相似文献

In the lung and mediastinum, salivary gland type tumors (SGTTs) can occur as either primary tumors or metastases from tumors arising in the major or minor salivary glands. This study reviewed the cytology cases of SGTTs in the lung and mediastinum diagnosed over a six‐year period at our institution. The specimens included a total of 22 exfoliative or aspiration cytology specimens identified in 16 patients. Two of the cases were primary tumors: adenoid cystic carcinoma (ACC) of the trachea and mucoepidermoid carcinoma (MEC) of the thymus. The remaining 20 tumors were metastases from the parotid, submandibular gland, tongue, nasal cavity, or soft palate. Eight of the 16 patients (50%) had a diagnosis of ACC, four (25%) had salivary duct carcinomas, two (12.5%) had MECs, one (6.25%) was a basaloid tumor, and one (6.25%) was polymorphous low grade adenocarcinoma. In our series, these SGTTs were more commonly metastatic in the lung or mediastinum (87.5% of the patients), and the most common histological subtype was ACC, followed by SDC. This study also illustrates the cytomorphologic features and diagnostic pitfalls of these unusual SGTTs. Diagn. Cytopathol. 2012. © 2011 Wiley Periodicals, Inc.  相似文献

Immunoreactivity of prostate-specific antigen (PSA), a kallikrein-like enzyme present in the seminal plasma, was demonstrated by indirect immunoperoxidase staining using a PSA antiserum in the apical cytoplasm along the luminal border of small-sized duct epithelial cells of the major salivary (parotid and submandibular) gland of both sexes (56/56, 100%). No PSA-like immunoreactivity was seen in large-sized duct epithelial cells and acinar cells. Minor salivary gland ducts were negative. When inflammatory and atrophic changes were observed, ductal expression of PSA-like immunoreactivity was decreased (12/37, 32%) and the site of intracellular localization often became diffusely cytoplasmic. The immunoreactivity was absorbed by human seminal plasma. Immunoreactivities of prostatic acid phosphatase and sex hormone receptors were undetectable in the salivary gland. Twenty-nine (34%) of 86 salivary gland tumors with ductal differentiation were immunoreactive for PSA mainly in the cytoplasm. A PSA monoclonal antibody ER-PR8 detected immunoreactivity in the prostate but not in the salivary glands or their tumors. Prostate-specific antigen-like immunoreactivity in small-sized (intercalated) duct epithelial cells of the major salivary gland and their tumors may be due to cross-reactivity of the antiserum with kallikrein-like substances.  相似文献

ObjectivesThis systematic review examines the effectiveness of communication technology interventions on HPV vaccination initiation and completion.MethodsA comprehensive search strategy was used to identify existing randomized controlled trials testing the impact of computer-, mobile- or internet-based interventions on receipt of any dose of the HPV vaccine. Twelve relevant studies were identified with a total of 38,945 participants.ResultsThe interventions were delivered using several different methods, including electronic health record (i.e. recall/reminder) prompts, text messaging, automated phone calls, interactive computer videos, and email. Vaccine initiation and completion was greater for technology-based studies relative to their control conditions.ConclusionThere is evidence that interventions utilizing communication technologies as their sole or primary mode for HPV vaccination intervention delivery may increase vaccination coverage.Practice implicationsCommunication technologies hold much promise for the future of HPV vaccination efforts, especially initiatives in practice-based settings.  相似文献
