Abstract
Bracken (Pteridium spp.) is a common weed that is consumed as food especially in Asia, and is suspected of promoting carcinogenesis induced by papillomaviruses in the digestive and urinary systems. This is particularly worrying because the incidence of head-and-neck cancers associated with the human papillomavirus (HPV) is rapidly increasing, and HPV co-carcinogens urgently need to be identified. This study tested the hypothesis that two bracken compounds, ptaquiloside and rutin, are able to promote head-and-neck and bladder carcinogenesis in HPV16-transgenic mice. Expression of HPV16 E6 and E7 in oral and bladder tissues was confirmed using quantitative real-time PCR. Mice were exposed orally to ptaquiloside (0.5 mg per animal per week for 10 weeks from 20 weeks-old) or rutin (413 mg kg-1 day-1 for 24 weeks from 6 weeks-old), sacrificed at 30 weeks-old and studied histologically. HPV16 E6 and E7 expression was higher in oral mucosa compared with the bladder (p 0.001). Importantly, ptaquiloside, but not rutin, increased the incidence of oral squamous cell carcinomas (p = 1.2 × 10-8) in HPV16-transgenic mice. Also, cancers of unexposed transgenic mice were restricted to the tongue base, while ptaquiloside-exposed mice showed multifocal lesions throughout the oral cavity. Wild-type controls showed no oral lesions. No bladder lesions were observed in any treated or untreated group. These results indicate that ptaquiloside from bracken is able to promote oral carcinogenesis initiated by HPV16. Rutin did not show any carcinogenic effects in this model. The absence of bladder lesions may reflect an insufficient incubation period or factors related to the specific viral oncogenes present in this model.

Abstract
OBJECTIVES Although the role of human papillomavirus (HPV) in the development of some carcinomas (eg, anogenital and oropharyngeal squamous cell carcinomas) is nondebatable, there is still significant controversy regarding the relationship of HPV and esophageal squamous cell carcinomas (SCCs). METHODS All cases were sampled at or near the gastroesophageal junctions in patients with reflux and/or known Barrett esophagus and appear to have been initially sampled "incidentally." Patients were all men, aged 56 to 80 years. None had a known history of other HPV-related disease. RESULTS We present four cases of high-grade squamous intraepithelial lesion of the gastroesophageal junction secondary to high-risk HPV that have identical histologic features to similar lesions of the anogenital tract. CONCLUSIONS Whether such lesions are at risk for developing into invasive SCC remains unclear.

Abstract
Epidemiological and mechanistic evidence on the causative role of human papillomaviruses (HPV) in esophageal squamous cell carcinoma (ESCC) is unclear. We retrieved alcohol- and formalin-fixed paraffin-embedded ESCC tissues from 133 patients seropositive for antibodies against HPV early proteins, from high-incidence ESCC regions: South Africa, China and Iran. With rigorous care to prevent nucleic acid contamination, we analyzed these tissues for the presence of 51 mucosotropic human alpha-papillomaviruses by two sensitive, broad-spectrum genotyping methods, and for the markers of HPV-transformed phenotype: (i) HPV16/18 viral loads by quantitative real-time PCR, (ii) type-specific viral mRNA by E6*I/E6 full-length RT-PCR assays and (iii) expression of cellular protein p16(INK4a). Of 118 analyzable ESCC tissues, 10 (8%) were positive for DNA of HPV types: 16 (4 tumors); 33, 35, 45 (1 tumor each); 11 (2 tumors) and 16, 70 double infection (1 tumor). Inconsistent HPV DNA+ findings by two genotyping methods and negativity in qPCR indicated very low viral loads. A single HPV16 DNA+ tumor additionally harbored HPV16 E6*I mRNA but was p16(INK4a) negative (HPV16 E1 seropositive patient). Another HPV16 DNA+ tumor from an HPV16 E6 seropositive patient showed p16(INK4a) upregulation but no HPV16 mRNA. In the tumor tissues of these serologically preselected ESCC patients, we did not find consistent presence of HPV DNA, HPV mRNA or p16(INK4a) upregulation. These results were supported by a meta-analysis of 14 other similar studies regarding HPV-transformation of ESCC. Our study does not support the etiological role of the 51 analyzed mucosotropic HPV types in the ESCC carcinogenesis.

Abstract
AIM To study the prevalence of human papillomavirus (HPV) in esophageal carcinoma in Tangshan, China, a high-incidence area. METHODS Formalin-fixed, paraffin-embedded tissue specimens from 198 patients who were pathologically diagnosed with esophageal squamous cell carcinoma from 2011 to 2013 were obtained from a pathology department in Tangshan. DNA was extracted from all 198 specimens to detect HPV by polymerase chain reaction (PCR). β-globin PCR was performed to check the quality of the DNA extraction procedure. PCR was performed to detect a wide range of HPV types, and type-specific PCR was performed to detect HPV types 16 and 18. Negative and positive controls were used for HPV 16 and 18 detection. RESULTS The DNA extraction method in this study appeared to be more effective than other previously reported methods. After DNA extraction, more than 98% of the tissue specimens had an acceptable result in the DNA qualification test (β-globin PCR). The overall prevalence of HPV in tumor tissues by GP6+/GP5+ PCR was 79.79%, and the prevalence of HPV types 16 and 18 was 40.40% and 47.47%, respectively. PCR demonstrated the presence of HPV, and direct sequencing confirmed the HPV genotypes. All HPV-positive PCR products were checked by DNA sequence analysis using DNAman and compared with the known HPV sequences listed in the Basic Local Alignment Search Tool database to evaluate the HPV types. This analysis confirmed the presence of HPV types 16 and 18. CONCLUSION DNA of high-risk HPV types 16 and 18 is present in esophageal tumors, implicating HPV as a possible etiologic factor for esophageal squamous cell carcinoma.

Abstract
SUMMARY The oncogenic potential of human papillomaviruses (HPV) is well known in the context of cervical carcinoma; however, their role in the development of oesophageal squamous cell carcinoma (OSCC) is less clear. We aimed to determine the extent of the association between HPV infection and OSCC. A comprehensive literature search found 132 studies addressing HPV and OSCC in human cases, and a meta-analysis was performed using a random-effects model. There was evidence of an increased risk of OSCC in patients with HPV infection [odds ratio (OR) 2·69, 95% confidence interval (CI) 2·05-3·54]. The prevalence of HPV in OSCC was found to be 24·8%. There was an increased risk associated with HPV-16 infection (OR 2·35, 95% CI 1·73-3·19). Subgroup analyses showed geographical variance, with Asia (OR 2·94, 95% CI 2·16-4·00), and particularly China (OR 2·85, 95% CI 2·05-3·96) being high-risk areas. Our results confirm an increase in HPV infection in OSCC cases.

Abstract
BACKGROUND Human papillomavirus (HPV) infection might be one of the potential risk factors for oesophageal cancer. However, the previous epidemiological findings were heterogeneous. AIM To explore the association between HPV infection and oesophageal cancer risk by means of meta-analysis. METHODS Studies on HPV infection and oesophageal cancer were identified, the prevalence of HPV infection and its association with oesophageal cancer risk were quantitatively summarised by meta-analysis. RESULTS A total of 8990 oesophageal squamous cell carcinoma (SCC) patients and 174 oesophageal adenocarcinomas patients were evaluated from 76 included studies. Summarised HPV prevalence in oesophageal SCC was 22.2% [95% confidence interval (CI), 18.3-26.7%], HPV-16 was the most frequently observed subtype with a summarised prevalence of 11.4% (95% CI: 8.2-15.7%). With respect to oesophageal adenocarcinoma, HPV prevalence was 35.0% (95% CI, 13.2-65.7%) and HPV-16 prevalence was 11.4% (95% CI: 8.2-15.7%). Due to the limited number of included studies on oesophageal adenocarcinoma, association analyses were performed to oesophageal SCC only. Significant association was observed between HPV infection and oesophageal SCC with a summarised odds ratio of 3.32 (95% CI, 2.26-4.87). According to HPV-16, the strength of the association was found to be 3.52 (95% CI, 2.04-6.07). CONCLUSIONS Human papillomavirus infection was observed to be associated with an increased risk of oesophageal SCC in this meta-analysis. However, due to the evident heterogeneity observed between the included studies and the strength of the association not as strong as observed for cervical cancer and laryngeal cancer, further studies are needed to clarify the relation and its underlying mechanisms.

Abstract
The etiological role of human papillomavirus (HPV) in cervical cancer has been well established. However, it is inconclusive whether HPV plays the same role in esophageal carcinogenesis. In this study, we detected HPV infection in 145 frozen esophageal tissues, including 30 normal epithelium (ENOR), 37 dysplasia (DYS) and 78 invasive squamous cell carcinoma (ESCC), and in 143 frozen cervical tissues composed of 30 normal epithelium (CNOR), 38 intraepithelial neoplasia (CIN) and 75 invasive squamous cell carcinoma (CSCC). The patients and symptom-free subjects enrolled in this study were from a high-incidence area for both ESCC and CSCC, Linzhou City, Northern China, from 2007 to 2009. The HPV infection analysis was conducted by using an HPV GenoArray Test Kit. We found that the high-risk HPV types accounted for more than 90 % of the HPV-positive lesions of esophagus and cervix tissues. The prevalence of high-risk HPV types increased significantly during the progression of both esophageal and cervical carcinogenesis (positive rate in esophageal tissues: 33 % ENOR, 70 % in DYS and 69 % in ESCC; positive rate in cervical tissues: 27 % in CNOR, 82 % in CIN and 88 % in CSCC; P < 0.001, respectively). Infection with the high-risk HPV types increased the risk for both DYS and ESCC by 4-fold (DYS vs. ENOR: OR = 4.73, 95 %CI = 1.68-13.32; ESCC vs. ENOR: OR = 4.50, 95 %CI = 1.83-11.05) and increased the risk for both CIN and CSCC by 12-fold and 20-fold (CIN vs. CNOR: OR = 12.18, 95 %CI = 3.85-38.55; CSCC vs. CNOR: OR = 20.17, 95 %CI = 6.93-58.65), respectively. The prevalence of high-risk types in ESCC patients was lower than that in CSCC patients (P = 0.005) and was significantly associated with the degree of ESCC tumor infiltration (P = 0.001). HPV 16 was the most prevalent subtype in both esophageal and cervical tissues. Single HPV infection increased significantly along with the progression of ESCC and maintained a high level in cervical tissues, regardless of whether they were CNOR or CSCC tissues. Our results showed that infection with HPV, especially the high-risk types, was positively associated with both esophageal and cervical cancers, suggesting that HPV also plays a role in the etiology of ESCC in the high-incidence area.

Abstract
PURPOSE A possible carcinogenic role of human papillomavirus (HPV) has been investigated in esophageal squamous cell carcinoma (ESCC) for nearly 30 years with mixed results. We performed a meta-analysis to assess the prevalence of "high-risk" HPV, HPV-16/18, in this disease. We also evaluated the association between infection with HPV-16/18 and ESCC risk by meta-analysis of case-control studies. METHODS Eligible studies published up to September 30, 2012 were retrieved via both computer searches of MEDLINE and EMBASE and manual review of references. A random-effects model was used to calculate summary prevalence and odds ratios (ORs) and corresponding 95% confidence intervals (CIs). RESULTS A total of 5755 cases of ESCC from 68 studies were included in this meta-analysis. Overall, 11.67% (95% CI, 7.74%-16.21%) of ESCC cases harbored HPV-16 and 1.82% (95% CI, 0.90%-2.95%) harbored HPV-18. In addition, meta-analysis of 10 case-control studies showed a significant increase in ESCC risk with HPV-16 infection (summary ORs = 3.55; 95% CIs, 2.05%-6.14%). However, this increased risk in ESCC was not made for HPV-18 infection (summary ORs = 1.25; 95% CIs, 0.46%-3.43%). CONCLUSIONS This meta-analysis indicated that HPV-16 and -18 can be detected in ESCC. HPV-16, but not HPV-18, is significantly associated with the risk of ESCC. However, it is early to conclude that both types of HPV are involved in esophageal carcinogenesis.

Abstract
Esophageal cancer (EC) is responsible for almost half a million deaths worldwide annually and has a multifactorial etiology, which may account for its geographical variation in incidence. In the last 30 years the potential of human papillomaviruses (HPV) as oncogenes or co-factors in the tumorigenic process of esophageal squamous cell carcinoma (ESCC) has been widely studied. While the etiology of HPV in cervical and certain other anogenital and aerodigestive cancers has been established, results regarding its role in EC have been largely inconclusive. A causal association can be evaluated only with a case-control study, where normal controls are compared to ESCC cases for the presence of HPV. We reviewed all studies investigating ESCC tissue for HPV DNA and identified 139 that met our inclusion criteria, of which only 22 were case-control studies. Our results support previous findings of higher levels of HPV detection in high-risk ESCC regions than in areas of low risk. In addition, we confirm that the role of HPV in ESCC remains unclear, despite an accumulation of studies on the subject. The variations in investigative technique, study design and sample types tested may account for the lack of consistency in results. There is a need for a meta-analysis of all case-control studies to date, and for large, well-designed case-control studies with adequate power to investigate the association. The potential benefits of prophylactic HPV vaccines could be evaluated if HPV is identified as an etiological factor in EC, highlighting the need for further research in this area.

Abstract
BACKGROUND Since the first reports in 1982 suggesting an aetiological role for human papillomavirus (HPV) in a subset of oesophageal squamous cell carcinomas (ESCC), the literature reporting HPV detection in ESCC has expanded rapidly. However no formal meta-analysis of this literature has been published yet. The objective of this study was to perform a systematic review and formal meta-analysis of the literature reporting HPV detection in ESCC. METHODS MEDLINE and Current Contents were searched through March 2012. The effect size was calculated as event rates and their 95% confidence interval (95% CI), with homogeneity testing using Cochran's Q and I² statistics. Meta-regression was used to test the impact of study-level covariates (HPV detection method, geographic origin of study) on effect size, and potential publication bias was estimated using funnel plot symmetry (Begg and Mazumdar rank correlation, Egger's regression, and Duval and Tweedie's trim and fill method). RESULTS Of the 1177 abstracts found, 152 studies were determined to be eligible for this meta-analysis. These 152 studies covered a total of 10,234 ESCC cases, analysed by different HPV detection methods in different geographic regions. Of these 10,234 cases, 3135 (30.6%) tested HPV-positive, translating to an effect size of 0.372 (95% CI 0.360-0.384; fixed effects model) and 0.290 (95% CI 0.251-0.31; random effects model). When stratified by HPV detection technique, there was a significant heterogeneity between the studies, but importantly, the between-strata summary comparison was not significant (random effects model; p = 0.440). In contrast, there was significant heterogeneity between the studies from the different geographic regions. In the maximum likelihood meta-regression, HPV detection method was not a significant study-level covariate, in contrast to the geographic origin of the study, which had a significant impact (p = 0.00005) on the summary effect size estimates. No evidence for significant publication bias was found in funnel plot symmetry testing. In the sensitivity analysis, all meta-analytic results appeared robust to all (n = 151) one-by-one study removals. CONCLUSIONS These meta-analysis results indicate that the reported wide variability in HPV detection rates in ESCC is not due to the HPV detection techniques, but is explained by the geographic origin of the study. These data substantiate the recently elaborated concept that ESCC might have a different aetiology in low-incidence and high-incidence geographic regions, HPV playing an important role only in the latter.

Abstract
Esophageal cancer is a prevalent cancer worldwide. Some studies have reported the possible etiology of human papillomavirus (HPV) in benign and malignant papillomas of the esophagus but the conclusions are controversial. In the present study, we investigated an esophageal papilloma from a 30-year-old male patient presenting aphasia. HPV DNA was detected by generic PCR using MY09/11 primers, and restriction fragment length polymorphism revealed the presence of HPV54, usually associated with benign genital lesions. Hypermethylation of the pINK4A gene was also investigated due to its relation to malignant transformation, but no modification was detected in the host gene. Except for an incipient reflux, no risk factors such as cigarette smoking, alcohol abuse or an infected sexual partner were recorded. Since esophageal lesions may have a malignant potential, HPV detection and typing are useful tools for patient follow-up.

Abstract
Esophageal cancer is a leading cause of cancer death, especially in developing countries. In high-risk regions, squamous cell carcinoma is the most common type of esophageal cancer, and its etiology remains poorly understood. The purpose of this study was to evaluate the association between human papillomavirus (HPV) infection and esophageal squamous cell carcinoma (ESCC) and related precursor lesions in a high-risk area of China. We conducted a cross-sectional study among adult inhabitants of Linxian, China. All subjects were interviewed about potential risk factors, had the length of their esophagus sampled by a balloon cytology examination and underwent endoscopy with mucosal iodine staining and biopsy of all unstained lesions. A multivalent HPV hybridization probe, Digene Hybrid Capture II (Gaithersburg, MD), which recognizes high-risk types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68, was used to determine the HPV infection status of the cytologic specimens, and the endoscopic biopsies were used to classify each subject's esophageal disease. 740 subjects completed the cytologic and endoscopic exams, and 702 had adequate cytologic and biopsy specimens. Using a cutpoint of > or =3.0 pg/ml of HPV DNA to define a positive test, HPV positivity was identified in 13% (61/475) of subjects without squamous dysplasia, 8% (8/102) with mild dysplasia, 7% (6/83) with moderate dysplasia, 16% (6/38) with severe dysplasia and zero (0/4) with invasive ESCC. Changing the cutpoint defining a positive test did not change the association of HPV infection and dysplasia grade. In this high-risk population, infection of esophageal cells with high-risk HPV types occurs in 13% of asymptomatic adults with no evidence of squamous dysplasia and a similar proportion of individuals with mild, moderate or severe dysplasia. This suggests that HPV infection is not a major risk factor for ESCC in this high-risk Chinese population. Further studies are warranted to determine if infection with this agent is associated with neoplastic progression in a subset of cases.

Abstract
Infection of high-risk human papillomaviruses (HPVs), particularly the HPV types 16 and 18 and mutation or aberrant expression of the p53 tumour suppressor gene, has strongly been implicated in human esophageal carcinoma, which shows a great variation in geographic distribution. Neither the reason(s) for such a variation nor the etiopathogenesis of the disease is clearly understood. The present study has been carried out to determine prevalence of high-risk HPV types 16 and 18 and the p53 gene mutation in patients from three distinctly different endemic geographic regions of India, viz. Kashmir, Dibrugarh, and New Delhi where esophageal cancer is most prevalent. The people from each of these regions differ considerably in their food, drinking, smoking and chewing habits (tobacco and betel nut) and ethnic background. While PCR was employed to detect high-risk HPV types 16 and 18 DNA sequences, PCR-SSCP and direct nucleotide sequencing was used for analysis of p53 mutation. Out of a total of 101 biopsy specimens of carcinoma esophagus analysed, the frequency of HPV was found to be the highest 14/32 (44%) in Dibrugarh followed by 33% (11/33) in Kashmir, but, interestingly, no high-risk HPV could be detected in New Delhi patients who showed the highest frequency (30.6%) of p53 mutation as against only 12.5% in Dibrugarh and 6.1% in Kashmir. The difference in the frequency of p53 mutation between the three regions was statistically highly significant (0.018). Out of a total of 21 nucleotide alterations observed, 12 missense, five frameshift and four were silent changes. The p53 exon 7 appears to be the 'hot-spot' for esophageal cancer as it alone was responsible for more than 76% (13/17) of mutations and more than 95% (20/21) of the patients with p53 mutation were smokers. The results demonstrate differential distribution of HPV infection and p53 mutation in esophageal cancer from different geographic regions of India and this could be due to variation in diet, drinking, and tobacco habit, including ethnic, socio-cultural and genetic variation.

Abstract
BACKGROUND Infection with high-risk human papillomavirus (HPV) has been implicated as one of the risk factors of esophageal squamous cell carcinoma (ESCC). Integration of viral DNA into host genome is essential for carcinogenesis since it promotes disruption of the HPV E2 gene, leading to abnormal expression of E6 and E7 oncoproteins. OBJECTIVES AND STUDY DESIGN To investigate the viral integration status of HPV-16 infection in ESCC, 35 HPV-positive ESCC specimens collected from Chinese patients were subject to real-time quantitative PCR for determination of physical status of HPV-16 by analyzing the ratios of E2 to E6 genes. RESULTS Our results showed that only 8.6% (3/35) of the HPV-16 positive specimens harbored exclusively the episomal form (i.e. E2/E6 ratio > or = 1), whereas the remaining 91.4% contained either only the integrated form (5.7%, with E2/E6 ratio = 0) or a mixture of episomal and integrated forms of viral molecules (85.7%, with E2/E6 ratios > 0 but < 1). Amongst the 30 cancer specimens carrying mixed integrated and episomal forms, 28 had E2/integrated E6 ratios of less than 1, indicating a predominance of integrated form of viral genes in these lesions. CONCLUSION Our finding of frequent integration of viral DNA in the host genome suggests that integration HPV-16 is common in ESCC from Chinese patients and implies that HPV infection may play a role in the pathogenesis of ESCC.

Abstract
We present a case of esophageal papillomatosis with underlying squamous cell carcinoma in situ. An esophageal lesion resected from a 74-year-old woman demonstrated histological findings characteristic of squamous cell papilloma (fibrovascular core and numerous finger-like projections covered with hyperplastic squamous epithelium) and severe dysplasia characteristic of squamous cell carcinoma. The relation of squamous papilloma and squamous cell carcinoma is discussed. It is suggested that esophageal squamous cell papilloma is a premalignant lesion.

Abstract
The first reports suggesting an involvement of human papillomavirus (HPV) in the development of both benign and malignant squamous cell tumours of the oesophagus date back to 1982. Since then, a substantial amount of literature has accumulated on this subject, summarised in this review. To date, 239 oesophageal squamous cell papillomas have been analysed in 29 separate studies using different HPV detection methods, with HPV being detected in 51 (21.3%) cases. Many more squamous cell carcinomas have been analysed: of the 1485 squamous cell carcinomas analysed by in situ hybridisation, 22.9% were positive for HPV DNA, as were 15.2% of the 2020 cases tested by the polymerase chain reaction. In addition, evidence derived from large scale serological studies, animal experiments, and in vitro studies is discussed in the light of the highly variable geographical incidence rates of oesophageal carcinoma worldwide. It may be that the (multifactorial) aetiology of oesophageal cancer differs greatly between those geographical areas with a low risk and those with a high risk for this disease. Oncogenic HPV types seem to play an important causal role, particularly in high risk areas.

Abstract
AIM To study the prevalence and the different types of human papillomavirus (HPV) in patients with oesophageal cancer from a high risk area of South Africa (Transkei). METHODS DNA samples from 50 paraffin wax embedded tissue sections were analysed by nested polymerase chain reaction (PCR) using the degenerate HPV L1 consensus primer pairs MY09/MY11 and GP5+/GP6+. Positive PCR samples were subjected to DNA sequence analysis. RESULTS HPV DNA was detected in 23 of the 50 samples. Sequence analysis revealed that most patients (11) harboured DNA to HPV type 11, whereas other types included DNA HPV type 39 (seven patients), type 16 (two patients), and type 52 (one patient). HPV type 39 has not previously been shown to be associated with oesophageal cancer. In contrast to earlier studies that have found HPV type 16 to be more frequently associated with oesophageal cancer, HPV type 11 was the predominant subtype in this study. CONCLUSIONS The high frequency of occurrence of HPV in oesophageal tumours (23 of 50 patients; 46%) implicates HPV as one of the possible aetiological factors in this disease. The finding that the low risk HPV subtypes predominate indicates that transformation may be effected via the E6 and E7 proteins.

Abstract
BACKGROUND Human papillomavirus (HPV) DNA has been identified in esophageal precancerous lesions and carcinomas. However, there are marked variations in the prevalence of HPV infection reported in different studies. Most previous studies on HPV and esophageal carcinomas have been based on a limited number of biopsy samples studied by different HPV detection methods with highly variable sensitivity and specificity, making systematic studies of larger series clearly warranted. METHODS A series of 1876 surgical specimens (primary tumor, adjacent epithelium, regional lymph nodes, resection margins) from 700 patients surgically resected for an invasive squamous cell carcinoma of the esophagus in the high-incidence area of China was analyzed for the presence of HPV DNA with screening in situ hybridization (ISH) using biotinylated HPV DNA probes and followed by type-specific ISH for HPV 6, 11, 16, 18, 30, and 53. RESULTS Of the 700 esophageal carcinomas, 118 (16.9%) were shown to contain HPV DNA sequences by screening ISH. Positive signals were most frequent in the cancer cells (16.6%), more rare in the surrounding hyperplastic and dysplastic epithelia (5.6%), and infrequently present in the resection margins (0.2%). HPV signals were also detected in cancer cells in 6.9% of the lymph node metastases. HPV types 6, 11, 16, 18, and 30 account for 39.8% of the HPV-positive lesions, of which the high-risk types HPV 16 and 18 were present in 27.1% (32 of 118). Notably, 60.2% of the HPV-positive lesions contained DNA sequences other than HPV types 6, 11, 16, 18, 30, and 53. CONCLUSIONS This study reports the largest series of esophageal cancers ever analyzed for the presence of HPV DNA. Our results confirm the presence of common mucosal HPV types in esophageal carcinomas but also suggest the involvement of other (novel?) HPV types that are unusually detected in genital cancers in a significant proportion of these lesions. The results further indicate that HVP has an etiologic role in esophageal carcinogenesis, at least in the high-incidence area of northern China.

Abstract
Papillomaviruses have proved to be the most complex group of human pathogenic viruses. Eighty-five genotypes have been fully characterized; approximately 120 additional isolates represent only partially characterized putative novel genotypes. Specific types, most notably human papillomavirus (HPV) types 16, 18, and a few others, have been shown to cause the majority of cervical cancers and their high-grade precursor lesions. The viral oncogenes E6 and E7 are required for the initiation and maintenance of the malignant phenotype in HPV-positive cancers. Proteins coded by these genes are multifunctional and interfere with important cell cycle regulatory proteins. Expression of viral oncogenes is tightly controlled in nondifferentiated keratinocytes by at least two signaling cascades, one operative at the functional level, the other at the transcriptional level. The latter has been partially characterized. Papillomaviruses are also suspected of playing a role in a subset of oropharyngeal cancers, in squamous cell cancers of the skin, and possibly also in esophageal cancers. Clinical trials are being conducted to test the preventive and therapeutic efficacy of HPV vaccines, directed particularly against HPV 16 and 18. If proven to be effective, their global application should have a measurable effect on the worldwide incidence of cancer.

Abstract
Women with both a history of high grade cervical intraepithelial neoplasia (CIN III) and breast carcinoma as second primary cancer were selected for studying the presence of HPV in breast carcinomas. Paraffin embedded material from 38 patients with 41 breast carcinoma cases after CIN III were examined by polymerase chain reaction (PCR) and in situ hybridization. By PCR we detected HPV 16 DNA in 19 out of 41 cases (46%) of the breast carcinomas. One case proved to be HPV 16 positive also by in situ hybridization. HPV 16 was also detected in 32 out of the 38 patients with CIN III (84%). All HPV 16 positive breast carcinomas were HPV 16 positive in their corresponding CIN III lesions. Eight patients with diagnosed breast cancer before the CIN III lesions were used as controls. None of these had HPV positive breast carcinomas. No cases were positive for HPV 11, 18, or 33. HPV 16 was detected in the primary tumours, in local metastases from HPV 16 positive tumours, in a distant HPV 16 positive breast carcinoma metastasis to the colon, and in other primary cancers in patients with HPV 16 positive breast carcinomas and HPV 16 positive CIN III. Estrogen and progesterone receptors were quantified in the HPV positive and HPV negative breast carcinomas, and there was no significant difference in the fraction positive in the two groups. Oncogenic HPV DNA might be transported from an original site of infection to other organs by blood or lymph, and possibly be a factor in the development of cancer in different organs.

Abstract
To elucidate the putative role of human papillomavirus (HPV) infection in the etiology of esophageal cancer, 121 formalin-fixed, paraffin-embedded specimens originating from a non-high-incidence area for this carcinoma, from Slovenia, were screened for HPV infection using eight different polymerase chain reactions (PCR). Three different HPV consensus primer sets and four primer sets specific for HPV types 6, 16, and 18 failed to detect HPV DNA sequences in any of the tumor samples. Fragments of human beta-globin gene that served as internal controls were successfully amplified from 120 of 121 specimens. Our study confirms the opinion that most esophageal cancers originating from non-high-incidence geographic areas of this cancer are not associated with HPV infection. According to the studies reviewed, it is likely that HPV infection plays a much more significant role in esophageal carcinogenesis in those areas of the world with a high incidence of ESCC.

Abstract
Controversial results regarding the presence and role of human papillomavirus in the development of oesophageal squamous cell carcinoma have been published. We used multiple broad-spectrum polymerase chain reactions to identify HPV DNA in oesophageal carcinomas from a low-incidence area. Paraffin embedded- and snap-frozen specimens from oesophageal cancer tissues of 63 patients were examined with a PCR technique with several primer pairs, capable of detecting most known HPV types. In none of the oesophagus cancer tissues could HPV DNA be detected. The role of HPV in this type of carcinoma in a low incidence area remains unclear.

Abstract
PURPOSE To investigate the role of human papillomavirus (HPV) types, 6, 11, 16 and 18 in corneal and conjunctival carcinoma, we examined 88 dysplastic corneal and conjunctival specimens and 66 controls that had been formalin-fixed and paraffin-embedded. METHODS Sections were graded for histological abnormality by light microscopy and the presence of HPV DNA was determined by polymerase chain reaction using LI consensus primers. RESULTS Human papillomavirus DNA was detected in 34 (39%) dysplasias and in five (7.5%) controls. Of dysplasias that were HPV-positive, 20 (59%) contained either types 16 or 18, 13 (38%) contained only types 6/11, while combinations of HPV types were present in 11 (32%). A histological correlation was found with HPV positivity (all genotypes) and unusually large ('epithelioid') dysplastic cells. CONCLUSION The present study demonstrates a lower incidence of HPV in corneal and conjunctival carcinoma than previously reported, but shows an unexpectedly high incidence of HPV 6/11 in conjunctival carcinomas.

Abstract
There is no scientific study that has investigated the association between human papilloma virus (HPV) and p53 mutation in Hong Kong Chinese patients with esophageal cancers. The aim of this survey is to evaluate in details the prevalence and relationship of HPV and p53 mutation in these patients with esophageal squamous cell carcinomas. Fresh tissues from the resected specimens of 70 Chinese patients (59 men, 11 women) with primary esophageal squamous cell carcinomas (20 well-differentiated, 36 moderately differentiated, and 14 poorly differentiated squamous cell carcinomas) were tested for the presence of HPV and p53 mutation using the polymerase chain reaction (PCR), single-strand conformational polymorphism (SSCP) analysis, and DNA sequencing. No HPV type 18 was detected, whereas HPV type 16 was identified in 8.6% (6 of 75) of the cases. p53 mutation was found in 44% (31 of 70) of the tumors. The mean ages of HPV-positive and HPV-negative groups of patients were 55 and 64 years, respectively (P = .046, t-test). There was no correlation between the prevalence of HPV and p53 mutation in these tumors. The presence of HPV and p53 also had no relation to the sex of the patients or to the grade of the carcinomas. It is concluded that the overall low prevalence of HPV in esophageal carcinomas may suggest that the virus may not play an important role in the pathogenesis of these tumors in Hong Kong Chinese patients. Also, p53 mutation and integrated HPV DNA are not mutually exclusive in esophageal cancer.

Abstract
In order to study the prevalence of papillomavirus antigen in canine epithelial neoplasms, 535 neoplastic and hyperplastic specimens of the skin, the cutaneous mucosa and the transitional epithelium were immunohistochemically stained with a polyclonal antiserum against papillomavirus antigen. A positive staining result occurred in 44.2% in a total of 95 papillomas and in 27% of 100 diagnosed squamous cell carcinomas, other tumours did not react with the applied antiserum. Papillomavirus antigen was detectable in 54.2% of all oral and ocular papillomas and in 37.0% of all cutaneous papillomas. The majority of the squamous cell carcinomas with detectable papillomavirus antigen were considered positive but not without restrictions. The average age of dogs with viral oral and ocular papillomas was 2.3 years, with viral cutaneous papillomas it was 3.2 years. The average age of dogs with virus-positive squamous cell carcinomas was nearly 11 years. Papillomavirus-like particles were demonstrated by means of transmission electron microscopy in three positive oral papillomas, in the positive squamous cell carcinomas virion detection failed.

Abstract
Several studies have documented the frequent occurrence of human papillomavirus (HPV) DNA in esophageal squamous cell carcinomas (ESCC) in patients from geographic regions where the incidence of this type of cancer is high, such as parts of China. However, the prevalence of HPV infection in ESCC in patients from low incidence geographic regions, such as North America, remains controversial. Therefore, this study evaluates the prevalence of HPV in ESCC in patients from North America, a region where the population is considered at low risk for the development of this neoplasm. ESCCs in 51 patients from three North American cities were analyzed for the presence of HPV DNA by a highly sensitive and specific polymerase chain reaction (PCR) method. Tumor DNA was extracted from formalin-fixed, paraffin-embedded tissue specimens and assayed by PCR using an L1 HPV consensus sequence primer, as well as HPV 16 and HPV 18 E7 region primers. The use of consensus primers to the L1 region allows for detection of most known HPV types and many novel HPV types. Appropriately sized reaction products were analyzed by restriction fragment length polymorphism (RFLP) to confirm the presence and type of HPV, and to exclude products produced by amplification of human DNA sequences. After complete analysis, only one case (2%) of ESCC was HPV DNA positive. This case was independently confirmed using L1 and E7 consensus primers as HPV type 16 and was the only case that tested positive with either assay. These results show that, in contrast to geographic regions where ESCC is prevalent, HPV infection occurs infrequently in association with ESCC in patients from North America.

Abstract
The papillomavirus family represents a remarkably heterogeneous group of viruses. At present, 77 distinct genotypes have been identified in humans and partial sequences have been obtained from more than 30 putative novel genotypes. Geographic differences in base composition of individual genotypes are generally small and suggest a low mutation rate and thus an ancient origin of today's prototypes. The relatively small size of the genome permitted an analysis of individual gene functions and of interactions of viral proteins with host cell components. Proliferating cells contain the viral genome in a latent form, large scale viral DNA replication, as well as translation and functional activity of late viral proteins, and viral particle assembly are restricted to differentiating layers of skin and mucosa. In humans papillomavirus infections cause a variety of benign proliferations: warts, epithelial cysts, intraepithelial neoplasias, anogenital, oro-laryngeal and -pharyngeal papillomas, keratoacanthomas and other types of hyperkeratoses. Their involvement in the etiology of some major human cancers is of particular interest: specific types (HPV 16, 18 and several others) have been identified as causative agents of at least 90% of cancers of the cervix and are also linked to more than 50% of other anogenital cancers. These HPV types are considered as 'high risk' infections. Their E6/E7 oncoproteins stimulate cell proliferation by activating cyclins E and A, and interfere with the functions of the cellular proteins RB and p53. The latter interaction appears to be responsible for their mutagenic and aneuploidizing activity as an underlying principle for the progression of these HPV-containing lesions and the role of high risk HPV types as solitary carcinogens. In non-transformed human keratinocytes transcription and function of viral oncoproteins is controlled by intercellular and intracellular signalling cascades, their interruption emerges as a precondition for immortalization and malignant growth. Recently, novel and known HPV types have also been identified in a high percentage of non-melanoma skin cancers (basal and squamous cell carcinomas). Similar to observations in patients with a rare hereditary condition, epidermodysplasia verruciformis, characterized by an extensive verrucosis and development of skin cancer, basal and squamous cell carcinomas develop preferentially in light-exposed sites. This could suggest an interaction between a physical carcinogen (UV-part of the sunlight) and a 'low risk' (non-mutagenic) papillomavirus infection. Reports on the presence of HPV infections in cancers of the oral cavity, the larynx, and the esophagus further emphasize the importance of this virus group as proven and suspected human carcinogens.

Abstract
BACKGROUND Human papillomavirus (HPV) DNA has been identified in esophageal carcinomas. However, the incidence of HPV varies significantly in different geographic locations. In the current study, neoplasms from two separate geographic regions were analyzed for the presence of HPV DNA: METHODS One hundred and ten esophageal squamous cell carcinomas, 83 from Beijing, China and 27 from Cincinnati, Ohio, were examined for the presence of HPV DNA: In situ hybridization and polymerase chain reaction (PCR) using both consensus primers for the HPV L1 gene and type specific primers for the E6 gene of HPV types 6, 16, and 18 were performed. RESULTS In situ hybridization failed to demonstrate any HPV type (6, 11, 16, 18, 31, 33, or 35) in any tumor specimen. Likewise, PCR using consensus primers for the HPV L1 gene was negative in all samples. Three of the Chinese specimens (4.29%) were positive for HPV using E6 type specific primers. One tumor contained HPV type 6 DNA, whereas the other 2 contained HPV type 16 DNA. One Cincinnati tumor (4.35%) was positive for HPV 16 by type specific primer. None of the specimens contained HPV 18 DNA. CONCLUSIONS The incidence of HPV DNA in esophageal carcinoma specimens from Beijing, China and Cincinnati, Ohio is similar. The incidence of HPV in tumors from Beijing is significantly lower than that reported for those from other regions of China where the incidence of esophageal cancer is higher. Thus, although HPV may play a role in esophageal carcinogenesis, this role may be more pronounced in those regions of the world with a high incidence of the disease, and may be less important in areas with moderate or low risks for esophageal cancer.

Abstract
BACKGROUND & AIMS Recent studies have suggested that esophageal human papillomavirus infection could be a risk factor for esophageal squamous cell carcinoma. The aim of this study was to evaluate the prevalence of human papillomavirus DNA sequences in the esophagus of French patients with esophageal squamous cell carcinoma. METHODS Multiplex polymerase chain reactions with consensus primers directed to the L1 gene or specific primers for human papillomavirus types 6, 11, 16, 18, 31, and 33 directed to E6 gene (40 cycles followed by restriction mapping of the amplified products) were used to determine the presence of human papillomavirus DNA sequences in esophageal squamous cell carcinoma (n = 75), normal adjacent mucosa (n = 49), and metastatic lymphadenopathies (n = 5). As an internal control, a target located in the embryonic myosin heavy-chain gene was used in each reaction. RESULTS Human papillomavirus DNA sequences could not be detected in any of the tumoral samples, the normal adjacent mucosa, or the metastatic lymphadenopathies. CONCLUSIONS Human papillomavirus seems not to be implicated in esophageal carcinogenesis, at least in French patients, because the viral genomes are not associated with esophageal squamous cell carcinomas.

Abstract
BACKGROUND Studies using DNA technology have reported the presence of human papillomavirus (HPV) DNA in esophageal carcinomas, suggesting that it could play a role in the pathogenesis of this tumor. In the present study, in addition to DNA from neoplasms, normal mucosa was screened for viral DNA, assuming that this would increase HPV detection substantially. METHODS Seventeen patients with esophageal carcinoma and 10 control subjects were studied. In 8 of the patients, normal mucosa was also available. Polymerase chain reaction (PCR) was performed using primers for the E6 region of HPV-16 and HPV-18. Koilocytosis, a commonly accepted histopathologic marker of viral infection, was studied, and results were correlated with PCR findings. RESULTS DNA from neoplastic lesions was positive for HPV-16 and HPV-18 in 8 of 16 (50%) and in 3 of 16 (18.8%), respectively. When tumor tissue and normal mucosa were available, PCR results were 3 of 8 (37.5%), 5 of 8 (62.5%), and 8 of 8 (100%) for HPV-16, in tumor, normal mucosa, and both. For HPV-18, results were 0 of 8 (0%), 5 of 8 (62.5%), and 5 of 8 (62.5%), respectively. In comparison with tumor samples, positivity in normal mucosa was increased for HPV-18 and for both viral genotypes (P = 0.01). No amplification was obtained in the control group. Koilocytosis was present in 33% of the cases. CONCLUSIONS These results suggested a high prevalence of HPV in esophageal carcinoma. The detection rate is significantly higher in normal mucosa specimens, suggesting that infection probably antedates tumor development. Koilocytosis was substantially less sensitive than PCR.

Abstract
Using morphological criteria, the presence of human papillomavirus (HPV) in oesophageal carcinomas has been inferred in patients from Finland and South Africa. However, studies to demonstrate the viral antigen in tissue sections of these tumours have proved disappointing. This study investigates 48 archival oesophageal carcinoma biopsies from South Africa for the presence of HPV DNA using non-isotopic in situ hybridization (NISH) with HPV DNA probes to HPV 6, 11, 16, 18, 31, and 33. HPV DNA sequences were detected in 25/48 (52 per cent) oesophageal cancers. HPV 16 was present in 84 per cent of the HPV-positive cancers. A NISH type 2 signal pattern (punctate/dot) was present in all HPV-positive tumours. This signal pattern was previously shown to represent integrated HPV DNA within host chromosome. Integrated HPV DNA in oesophageal cancers has also been demonstrated in patients from China and Japan. In addition, the prevalence of HPV DNA in oesophageal cancers from high-risk countries like South Africa (52 per cent) and China (49 per cent) would appear to be consistent.

Abstract
We studied 40 formalin-fixed, paraffin-embedded esophageal squamous cell carcinomas from a high risk region for this tumor for the presence of human papillomavirus (HPV) DNA by the polymerase chain reaction (PCR). We used two general consensus primers from a highly conserved E1 region of HPV types 6, 11, 16, and 18. Human papillomavirus DNA was detected in 60% (24 of 40) of the cases without relation to the tumor grade. Two lymph node metastases had the same HPV types as the primary tumor. Human papillomavirus types were determined in the 24 HPV-positive cases by Southern blot analysis of amplified DNA. Human papillomavirus type 6 was detected in 50% (12 of 24) of the cases, HPV type 16 in 8% (two of 24), and HPV types 6 and 16 in 17% (four of 24); in 25% (six of 24) of the cases the type was unknown. Human papillomavirus types 11 and 18 were not detected. Esophageal mucosa adjacent to the tumor was studied for morphological changes of HPV effect in 27 cases. Adjacent esophageal mucosa in 16 HPV-positive tumors showed statistically significant (P < .05) koilocytosis in six cases. Papillomatosis was the next most frequent finding in four cases. This study supports the role of HPV in the causation of esophageal squamous cell carcinomas, especially in high risk regions for this tumor.

Abstract
Epidemiological evidence suggests that alcohol intake, use of tobacco, ingestion of mycotoxins and nitrosamines and nutritional deficiencies are high-risk factors for the development of oesophageal cancer. Similarly, viral infections have been postulated to play a role in some tumours. However, the molecular events underlying the development of oesophageal carcinoma are poorly understood as yet. Loss of p53 tumour-suppressor gene function has been found in different human malignancies, and it can occur in a variety of ways, including gene mutation and interaction with the E6 protein of oncogenic human papillomaviruses (HPVs). Because the oesophageal mucosa is potentially exposed to mutagens and HPVs, we studied DNA samples derived from nine HPV-positive squamous cell carcinomas and 12 HPV-negative tumours. Exons 5-9 of the p53 gene containing phylogenetically conserved domains were examined using the polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) technique. HPV detection was done using DNA in situ hybridisation with biotin-labelled HPV DNA probes. Mutations were detected in eight (38%) out of the 21 cases. Three mutations were found in exons 5/6, three in exon 7 and two in exon 8/9. Six (50%) of the 12 HPV-negative carcinomas showed p53 mutations. Two (22.2%) of the nine HPV-positive carcinomas were found to contain p53 mutations as well; one contained HPV 16 DNA sequences and showed p53 mutation in exon 8/9, and the other was HPV 6/11 positive with the mutation in exon 5/6. Although mutations were more common in HPV-negative tumours (50.0% vs 22.2%), the difference in p53 mutations in HPV-positive and -negative tumours did not reach statistical significance (P = 0.1946). These data indicate that inactivation of the p53 gene is a frequent event in oesophageal squamous cell carcinomas and such an inactivation might be an important molecular pathway for the development of oesophageal cancer. The findings of p53 mutations in HPV-positive oesophageal carcinomas suggest that HPV and p53 mutation were not mutually exclusive events. The presence of frequent mutations of p53 gene in both HPV-positive and -negative oesophageal carcinomas suggests a dominant role of environmental carcinogens in oesophageal carcinogenesis.

Abstract
BACKGROUND/AIMS Esophagus squamous cell carcinoma has much geographic variation. A variety of genetic and environmental factors have been implicated in the pathogenesis of esophagus squamous cell carcinoma. This study was undertaken to determine whether the human papillomavirus is present in these tumors. METHODS A radioactive nested polymerase chain reaction was used to determine the presence of human papillomavirus in esophagus squamous cell carcinoma DNA and adjacent normal mucosa DNA from different regions of the world. Restriction fragment length polymorphism analysis was used to determine which particular human papillomavirus genotype was present. RESULTS Human papillomavirus was identified in 14% of esophageal squamous cell cancer DNA but in none of the adjacent normal mucosa DNA available for some of the samples. Positive samples were found to contain sequences specific for high-risk human papillomaviruses, either types 16 or 18. In addition, a novel human papillomavirus genotype was detected in another 10% of the samples. CONCLUSIONS Esophagus squamous cell carcinoma is associated with the expression of human papillomavirus genotypes 16 and 18, which are linked to transformation of squamous epithelial cells. In addition, a novel human papillomavirus genotype that was identified may be associated with pathogenesis in esophagus squamous cell cancer.

Abstract
This study assessed squamous cell papillomas of the human esophagus for the presence of human papillomavirus (HPV) and correlated the results with histological features. Twenty-three lesions obtained by endoscopic biopsy from 17 patients were studied, first by in situ hybridization (ISH) for HPV types 6-11, 16-18, 18, and 31-33-51, and second by the polymerase chain reaction (PCR) with amplification of multiple HPV types and demonstration of amplified product by ethidium bromide staining and Southern blot hybridization for HPV types 6-11, 16, and 18 in each case. Evidence of HPV DNA was found in only one lesion, which showed HPV type 6-11 by ISH and HPV positivity by Southern blotting of the amplified product after the PCR. This case exhibited histological features suggestive of HPV infection, although no morphological changes specific to the lesion were identified. The remaining 22 lesions, including those from cases in which multiple papillomas were present, were negative for HPV. The results show that HPV DNA is frequently not detectable in esophageal squamous cell papillomas, even when highly sensitive techniques are used. These findings are consistent with the hypothesis that other pathogenetic mechanisms, such as mucosal injury and repair, are important in the etiology of these lesions.

Abstract
BACKGROUND Infections with specific types of human papillomavirus (HPV) have been closely linked with human squamous cell carcinomas, those of the anogenital tract in particular. Increasing number of reports also suggest that HPV infection could be a risk factor for esophageal cancer. However, most of the previous studies on HPV involvement in esophageal carcinomas have included only small numbers of biopsy specimens, thus necessitating additional studies based on extensive series of esophageal samples. METHODS A series of 776 biopsy specimens derived from 363 patients who had undergone esophagectomy for squamous cell carcinoma in the high-incidence area of China were analyzed for the presence of HPV DNA by screening and specific typing in situ hybridization with biotinylated HPV DNA probes. RESULTS Under low-stringency conditions, 85 (23.4%) tumors were demonstrated to contain HPV DNA: Positive signals were found on the nuclei of cancer cells in 71 (19.6%), in the surrounding epithelial cells with hyperplastic or dysplastic changes in 13 (3.6%), in the cancer cells and the surrounding epithelial cells in 10 (2.8%), and in the resected margins in 1 (0.3%). Thirty-four (40%) of the 85 HPV-positive tumors were shown to contain at least one type of HPV 6, 11, 16, 18, or 30 DNA sequences. HPV 16 was the type found most frequently, occurring in 18.8% of the 85 HPV-positive specimens. In addition to the primary tumors, HPV DNA sequences were found in 12.3% (7 of 57) of the lymph node metastases. CONCLUSION The results confirm the previously reported HPV involvement in esophageal squamous cell lesions and implicate HPV as a potential etiologic agent in the multifactorial pathogenesis of esophageal carcinoma.
