Abstract
Introduction: The etiology of esophageal squamous papilloma (ESP) is largely unknown. Previous studies have shown a variable association with human papillomavirus (HPV) with conflicting data. The aim of this study was to further investigate the possible association of HPV in our ESP series using RNA in-situ hybridization (ISH) and compare study groups from the United States of America and China. Methods: Demographic and clinical data of patients with ESP were retrieved from the University of California Los Angeles (UCLA) (1/2016-3/2019) and Peking Union Medical College Hospital (PUMCH) (9/2014-3/2019) pathology databases. Hematoxylin and eosin slides were reexamined. Confirmed cases were examined by high- and low-risk HPV RNA ISH. Results: For the UCLA cohort, 13 429 upper endoscopies were performed and 78 biopsies from 72 patients were identified as ESP (F:M = 45:27, 66.7% > 45 years). Seventy-four (94.9%) biopsies were designated as polyps or nodules and 46.6% were located in the mid-esophagus. Other abnormal findings included gastroesophageal reflux disease (48.6%), hiatal hernia (38.9%), and esophagitis (36.1%). For the PUMCH cohort, 63 754 upper endoscopies were performed and 73 biopsies from 71 patients were identified as ESP (F:M = 48:23, 71.8% > 45 years). Sixty-four (87.7%) biopsies were designated as polyps or nodules and 57.5% were located in the mid-esophagus. Other abnormal findings included esophagitis (19.7%), and hiatal hernia (8.5%). No features of conventional cytologic dysplasia or viral cytopathic change were found. None of the cases was associated with squamous cell carcinoma, and none showed positive HPV RNA ISH results. Conclusions: No association was found between ESP and active HPV infection in our 2 cohorts. Other etiopathogenetic mechanisms, such as aging, might contribute to the development of these innocent lesions.

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
BACKGROUND AND STUDY AIMS Esophageal squamous papilloma (ESP) is a rare lesion. The aims of this study were to assess the prevalence of ESP in northeastern France and the risk of associated squamous cell carcinoma (SCC). PATIENTS AND METHODS The charts of 78 patients who were diagnosed with ESP between January 2005 and February 2013 at three hospitals in northeastern France were reviewed. RESULTS A total of 55 305 endoscopies were performed and 78 ESP were diagnosed (0.01 %). Patients with ESP included 44 males (56.4 %), 34 females (43.6 %); median age 50, interquartile range (IQR) 19 - 86. Median follow-up was 21 months (IQR 0 - 91 mo) and median time between first and second endoscopy was 7 months (IQR 0.5 - 74 mo). Of the total number of patients, 35 (44.9 %) had a second endoscopy. Main endoscopy indication was dyspepsia (24.4 %). Most ESP were isolated (93.6 %) and located at distal esophagus (27 cm, IQR 16 - 40 cm). Median size was 3 mm (IQR 1 - 20 mm). ESP-associated endoscopic lesions were hiatal hernia in 12 patients and esophagitis in 11 patients. Endoscopic treatment was mainly excisional biopsies (60.3 %). Human papillomavirus (HPV) was not detected in the 6 patients with available data. Low dysplasia was found in 2 ESP. During follow-up endoscopies, 2 SCC were detected in 2 different patients; the first SCC was located at the previous resection site of the ESP and the second had a different location. Prevalence of associated cancer was 1.3 %. CONCLUSION Prevalence of ESP in northeastern France is similar to that previously reported. Endoscopic findings were also broadly the same as in previous reports. The occurrence of dysplasia and SCC should strongly encourage the endoscopist to totally remove the ESP and to start an endoscopic surveillance, given the potential risk of malignant transformation.

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
Since first suggested (in 1982), etiological role for human papillomavirus (HPV) in esophageal papillomas has aroused increasing interest. The objective of this study was to perform systematic review and formal meta-analysis of the literature reporting on HPV detection in esophageal squamous cell papillomas (ESCP). Literature was searched through May 2012. The effect size was calculated as event rates (95% CI), with homogeneity testing using Cochran's Q and I(2) statistics. Meta-regression was used to test the impact of study-level covariates (HPV detection method, geographic origin) on effect size, and potential publication bias was estimated using funnel plot symmetry. Thirty nine studies were eligible, covering 427 ESCPs from different geographic regions. Altogether, 132 (30.9%) cases tested HPV positive; effect size 0.375 (95% CI 0.319-0.434) using the fixed-effects (FE) model and 0.412 (95% CI 0.295-0.540) using the random-effects model. In meta-analysis stratified by (i) HPV detection technique and (ii) geographic study origin, the between-study heterogeneity was not significant (p = 0.071 and p = 0.105, respectively). In meta-regression, HPV detection method (p = 0.260) and geographic origin (p = 0.436) were not significant study-level covariates accounting for the heterogeneity in HPV prevalence. Some evidence for publication bias was found only for PCR-based studies, with a marginal impact on summary effect size estimates. In sensitivity analysis, all meta-analytic results were robust to all one-by-one study removals. In stratified meta-analysis and formal meta-regression, the variability in HPV detection rates in ESCPs is not explained by the HPV detection method or geographic origin of the study.

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
AIM: To investigate the presence of human papillomavirus (HPV) in esophageal squamous papilloma (ESP) and determine p16, p53 and Ki67 expression in a Mexican cohort.
METHODS: Nineteen cases diagnosed as ESP, corresponding to 18 patients were reviewed; nineteen cases of normal esophageal mucosa were used as negative controls. HPV detection was performed by amplified chromogenic in situ hybridization (ACISH) using a wide spectrum-cocktail probe and PCR.
RESULTS: The average age at presentation was 46.3 years (range 28-72 years). Patients included four (22.22%) males and 14 (77.77%) females. The most frequent location was upper third (11 cases), followed by middle third (3 cases) and unknown site (5 cases). Immunohistochemistry (IHC) revealed basal and focal p53 expression in 17 cases (89%); p16 was expressed in eight cases (42.10%) and the Ki67 index ranged from 10% to 30%. HPV was detected in 14 out of 16 cases (87.5%) by ACISH: Twelve showed diffuse nuclear patterns and two showed granular patterns. HPV DNA was identified by PCR in 12 out of 14 cases (85.7%). Low-risk HPV types were detected in the most of the cases.
CONCLUSION: This study provides identification of HPV infection in almost 80% of ESP using either ACISH or PCR; overall, all of these lesions show low expression of cell-cycle markers. We suggest ACISH as an alternative diagnostic tool for HPV detection in ESP.

Abstract
The incidence of esophageal squamous cell carcinoma varies greatly with race and geographic location. It has been suggested that human papillomavirus (HPV) is involved in the pathogenesis of esophageal cancers, and that the incidence of esophageal cancers associated with HPV depends on the geographic location of the patient population. In studies performed on tumor specimens collected from areas with a low incidence of esophageal squamous cell carcinomas, HPV infection was detected in only a small percentage of tumors, whereas studies performed on specimens obtained from areas with a high incidence of esophageal squamous cell carcinomas provided strong evidence that HPV plays a significant role in esophageal carcinogenesis. To elucidate the putative role of HPV infection in the etiology of esophageal cancer in Korea, a total of 129 formalin-fixed, paraffin-embedded tumor specimens, eight fresh tumor tissues and 40 normal esophageal tissues were screened for HPV infection by polymerase chain reaction using consensus primers for HPV types 16, 18, 31, 33, 35, 52b and 58 and type 16-specific primers. SiHa cell line, formalin-fixed, paraffin-embedded cervical squamous cell carcinoma specimens were used as positive controls for HPV infection. Fragments of human beta-globin gene, which served as the internal controls, were successfully amplified from 102 of the 129 cancer specimens and from all the normal and fresh cancer tissues, while consensus and type 16-specific primers failed to detect HPV DNA sequences in any of the esophageal samples. The DNA extracted from the SiHa cell line and uterine cervical cancers were positive when both the consensus and type-specific primers were used. The results of this study suggest that HPV is not associated with esophageal carcinogenesis in Korea.

Abstract
Esophageal squamous cell cancer is highly prevalent in south-western Kenya. The role of human papillomavirus (HPV) in esophageal cancers from this region was evaluated. Biopsies of 29 esophageal squamous cell cancers were assayed for HPV DNA sequences by reverse line blot polymerase chain reaction, using 27 HPV type-specific probes. Viral sequences were found in none of the specimens. These results suggest the HPV is unlikely to be an etiologic factor for esophageal squamous cell cancers in this region.

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
Esophageal squamous cell carcinoma (ESCC) is the predominant histologic subtype of esophageal cancer and characterized by high mortality rate and geographic differences in incidence. With the advances in the field of molecular biology, our understanding of the pathogenesis, epidemiology and behavior of ESCC continues to evolve. The recent development includes research in etiopathogenesis (viruses and cancer susceptibility genes), keratins, tumor related genes (oncogenes, tumor suppressor genes, genes involved in metastasis and apoptosis genes), proliferation-related factors (nuclear proteins, flow cytometry/morphometry, argyrophilic nucleolar organizer region) and factors related to metastases (cell adhesion molecules and enzymes related to degradation of extracellular matrix). There are ranges of molecular techniques potentially available to complement the traditional approaches in the management of ESCC. On the other hand, critics are needed in the interpretation and translation of these research findings from laboratories to clinics. Further investigations, education and collaborations between the various scientific and clinical disciplines are important to successful application of these molecular findings aiming at improving management of patients with ESCC.
