人乳瘤病毒16型和EB病毒感染与口腔鳞癌关系   总被引:2,自引:0,他引:2  
用多聚酶链反应技术为21例口腔鳞癌及癌旁正常组织成对标本中的人乳头瘤病毒16型(HPV16)和EB病毒(EBV)DNA作检测。结果口腔鳞癌和癌旁正常组织HPV16DNA阳性率分别为52.4%和14.3%,EBV为85.7%和33.3%,HPV16和EBV均为阳性者分别为47.6%和9.5%,癌组织和癌旁正常组织间统计学上均有显著性差异。提示口腔粘膜HPV16或EBV感染均与口腔鳞癌发生有关。HPV16和EBV在口腔粘膜感染可能有协同致口腔鳞癌作用。  相似文献

Commercial biotinylated DNA probes specific for human papillomavirus (HPV) types 6 and 11; 16 and 18; and 31, 33, and 35 were used for in situ hybridization analysis of 105 oral mucosal specimens from 5 cases of verruca vulgaris, 15 cases of condyloma acuminatum, 30 cases of squamous papilloma, 20 cases of hyperkeratosis/acanthosis, 15 cases of epithelial dysplasia, 5 cases of carcinoma in situ, and 15 cases of squamous cell carcinoma. Positive hybridization signals were found in 26 specimens (24.8%). Only HPV-6/11 was detected. HPV DNA occurred significantly more often (p less than 0.005, chi-square analysis) in condyloma acuminatum (100%) and verruca vulgaris (100%) than squamous papilloma (13.3%), hyperkeratotic/acanthotic lesions (10%), and malignant and premalignant lesions (0%). The tongue (19.1%) and labial epithelium (17.1%) were infected most frequently. Nuclear reaction products indicating HPV infection were associated primarily with koilocytes. These results demonstrate the usefulness of commercial biotinylated probes for HPV DNA analysis in routine paraffin-embedded lesion specimens. They confirm HPV involvement in benign lesions of the oral mucosa but fail to associate HPV infection with oral cancer and precancer.  相似文献

Human papilloma virus in erosive oral lichen planus   总被引:1,自引:0,他引:1  
Several types of human papilloma viruses (HPV) have been associated with benign and malignant squamous cell tumours of mucosal epithelium. To identify HPV in erosive oral lichen planus (OLPe), considered as a premalignant lesion, tissues from 20 patients were examined by Southern blot hybridization with 32P-labeled HPV DNA probes. Type 11 was found in 6 of the lesions while HPV types 6, 16 and 18 were not detected in any of the tissues examined. Using a type-specific polymerase chain reaction (PCR) assay for HPV-6, 11, 16 and 18, HPV-11 was detected in 8 of the samples (all of those positive by Southern blot), and, in addition, HPV-6 was found in 5 samples and HPV-16 in 3 samples. Overall, by the more sensitive PCR assay, 65% of samples were positive for HPV DNA. The finding of HPV DNA in many of the samples using two different techniques indicates a high prevalence of HPV in the OLPe afflicted oral mucosa. However, the role of HPV in the pathogenesis of OLPe has yet to be determined.  相似文献

BACKGROUND: Several epidemiologic studies have shown a broad variation in the prevalence of human papillomavirus (HPV) in oral precancerous tissues and oral carcinomas. METHODS: Biopsies and superficial scrapes of lesions, clinically suspected of HPV infection, were taken from patients with potentially malignant and malignant oral lesions, and subject to HPV DNA detection by PCR-Southern blot analysis. RESULTS: From 22 patients with potentially malignant and malignant lesions analyzed, 41% of the biopsies were HPV DNA positive, whereas 95-100% of the superficial scrapes were positive (McNemar, P < 0.0001). Clinical presumption of HPV infection detected 67% (P < 0.0001) of the HPV DNA positive cases compared with 48% (P < 0.0001) determined by cytology and histopathology. The prevalence of HPV 6, 11, 16 and 18 in the oral mucosa was studied in 59 individuals. While 9% of normal controls were HPV DNA positive, 100% of the patients with potentially malignant and malignant lesions were HPV DNA positive, and the prevailing genotype was HPV 16 followed by HPV 18. CONCLUSIONS: The higher HPV DNA detection rate in superficial oral scrapes than in biopsies suggests that accurate epidemiological information on oral HPV infection/oral carcinogenesis depends not only on the DNA detection technique, but also on the tissue/cell sampling procedure.  相似文献

Background:  Evidence is accumulating for the aetiological role of human papillomavirus (HPV) in the pathogenesis of potentially malignant oral mucosal lesions and squamous cell carcinomas.
Methods:  Paraffin tissue sections from 49 patients with 'white patches' of the oral mucosa were investigated histologically, by broad-spectrum PCR followed by genotyping and chromogenic in situ hybridisation (CISH).
Results:  Histologically, 33 flat hyperplasias and 16 papillary hyperplasias were diagnosed. Twenty-two of 28 samples studied (78.6%) were positive for HPV DNA by PCR and six were negative. The following HPV types were detected in decreasing order of prevalence: HPV 35, HPV 6, HPV16, HPV 53, HPV 18, HPV 51 and HPV 55. Seventeen samples (60.7%) contained high-risk HPV DNA. Using CISH, ≥ 1 HPV signals were detected at least in a few epithelial cells in 95% of cases studied. All but one case were positive with the high-risk HPV probe and all HPV infections contained low viral load. Concordant positive results both by PCR and CISH were detected in 14 of 19 cases (73.7%) analysed.
Conclusions:  The high prevalence of HPV infection in hyperplastic 'white patches' of the oral mucosa supports the putative role of HPV at an early stage of oral carcinogenesis. These results further indicate that the majority of white oral mucosal lesions – flat, exophytic, wart-like or papillary proliferations – could be considered as the clinical manifestations of oral HPV infection. This finding has clinical relevance regarding therapy and patient management and may help in elucidating the role of HPV infection in oral carcinogenesis.  相似文献

OBJECTIVE: To investigate the prevalence of human papillomavirus (HPV) infection in normal oral mucosa, and to observe the natural history in the oral cavity in oral swab samples collected from healthy volunteers on Miyako Island, Okinawa, Japan. STUDY DESIGN: The prevalence of HPV infection in oral buccal mucosa cell scrapes collected between 2000 and 2002 from a cohort of 668 healthy volunteers was determined. HPV DNA was detected by consensus polymerase chain reaction (PCR) using MY09/MY11 primers followed by direct cycle sequencing. Just over 2 years later the HPV-positive participants were reevaluated. RESULTS: Of the 668 subjects, 662 samples were analyzed for HPV. HPV DNA was detected in 4 (0.6%) specimens. HPV type 16 (HPV16), HPV53, and HPV71, mucosal types, and HPV12, a cutaneous type, were all identified by direct sequencing. In the follow-up survey, the HPV71- and HPV12-positive participants again tested positive, while HPV DNA was not detected in the HPV16- and HPV53-positive participants. CONCLUSION: The results of this study among healthy individuals from Miyako Island suggest that oral HPV infection is uncommon. In this cohort, HPV71 and HPV12 were persistent, while HPV16 and HPV53 were transient in normal oral mucosa.  相似文献

Analysis of human papillomavirus DNA in oral squamous cell carcinomas   总被引:4,自引:0,他引:4  
Evidence from several laboratories suggests that HPV plays a role in the etiology of squamous cell carcinomas of the oral cavity. A rnultifactorial risk factor profile for the development of oral cancer may include HPV in addition to well-established risk factors such as tobacco and alcohol use. The prevalence of oral carcinomas repotted to be associated with HPV has varied widely due to differences in the sensitivity of the assay used for HPV detection. The aims of this study were: (1) to ascertain the prevalence of HPV DNA in oral squamous cell carcinomas using the most sensitive technique available, the polymerase chain reaction; (2) to determine the type of HPV in the tumors; and 3) to correlate the virologic data with other risk factor data obtained from patients' records. Fourteen (78%) of 18 primary tumors, 6 (67%) of 9 normal epithelial tissues from the patients and 5 (100%) of 5 neck metastases were HPV DNA-positive. Of the 14 HPV DNA-positive primary tumors, specific typing revealed HPV 16 in 2, HPV 18 in 2, HPV 16 and IS in 5, HPV 6/11, 16 and 18 in 4, and HPV 6/11 in 1. HPV types in the normal or metaslatic tissue were usually the same as those in the respective primary tumor. There was no significant association between HPV presence and any of 12 factors or patient characteristics studied.  相似文献
