Abstract
BACKGROUND Lymphoepithelial carcinoma of the salivary glands (LECSG) is a rare disease in the Western hemisphere that is typically associated with an EBV infection. The molecular mechanisms of LECSG tumorigenesis are poorly understood. RESULTS Here we report a case of EBV-associated LECSG with an unusual immunophenotype. The tumor exhibited bi-morphic histological features with a mutually exclusive expression of HER2 and p16. The p16-positive domain of the tumor immunohistochemically co-expressed late membrane protein 1 (LMP-1), while the HER2 positive domain did not. Both tumor regions expressed SSTR2. METHODS In situ hybridization confirmed the EBV origin of the tumor while extensive immunohistochemical characterization and the recently established RNA-based next generation sequencing panel ("SalvGlandDx" panel) did not reveal evidence for another salivary gland neoplasm. No HPV co-infection was detected by in situ hybridization or PCR-based screenings and no ERBB2 gene amplification was detected by fluorescence in situ hybridization. CONCLUSION These findings suggest tumor heterogeneity and lack of genomic aberrations in EBV-associated LECSGs. The heterogenous and unusual immunohistochemical features explain the diagnostic difficulties and simultaneously extend the immunophenotype spectrum of this tumor entity.

Abstract
OBJECTIVE To explore the epidemiological characteristics of patients with lymphoepithelial carcinoma (LEC) of the head and neck and the prognostic factors. METHODS We conducted a retrospective cohort study of cases of head and neck LEC retrieved from the Surveillance, Epidemiology and End Results database. Kaplan-Meier survival analysis and the log-rank test were employed to assess overall survival (OS) and cancer-specific survival (CSS). Univariate and multivariate analyses were used to construct Cox regression models. We established nomograms to predict OS and CSS among patients with nasopharyngeal LEC, who were divided into high- and low-risk groups based on the OS nomograms to compare the effects of treatment using the restricted mean survival time (RMST). RESULTS The 5-year OS and CSS rates of the cohort were 70.8% and 74.8%, respectively. Advanced age, unmarried status, black race, distant metastasis, and the absence of surgical treatment were significantly associated with decreased survival rates. RMST did not differ between the combined treatment (radiotherapy and chemotherapy) and radiotherapy monotherapy groups, but chemotherapy alone displayed poor efficacy. CONCLUSIONS Head and neck LEC is associated with a favorable prognosis. Radiotherapy plays a significant role in managing patients with nasopharyngeal LEC, which is influenced by multiple prognostic factors.

Abstract
ABSTRACTS Lymphoepithelial carcinoma (LEC) of the larynx is a rare tumor comprising 0.2% of all laryngeal neoplasms. To our knowledge, less than 50 cases of LEC of the larynx are reported in the literature. The lack of specific guidelines leads to uncertainty on this rare entity's diagnosis, treatment, and follow-up. The association of Epstein-Barr virus as a predisposing factor of LEC has been proposed in a few reports. Although the occurrence of LEC in the larynx is infrequent, it is essential to differentiate it from squamous cell carcinoma. Immunohistochemistry should be performed to demonstrate cytokeratin expression. It is a very aggressive tumor with high metastatic potential; however, it is hard to comment on the disease outcome of LEC of the larynx because only case reports are available in the literature. Here, we report a case of LEC of the larynx (CK +ve, CD 45 -ve, and EBER-ISH -ve) in a 49-year-old male. Initially, the patient was planned for surgery but defaulted. He reported back after 4 months, and there was clinicoradiological disease progression. Because of the unresectable status and poor general condition, he received palliative radiotherapy only. Additionally, we have conducted a pooled analysis of the individual cases of LEC of larynx available in the literature to understand the clinical behavior to optimize the treatment of these patients.

Abstract
In this article, we review the chapter on tumors of the larynx, hypopharynx, trachea and parapharyngeal space in the new edition of the WHO book, focusing on the new developments in comparison to the previous edition. Squamous cell carcinoma (SCC) and its variants are by far the most common malignancies at these locations, with very limited new insights. The most important is the introduction of new targeted treatment-checkpoint inhibitors, with a new task for pathologists, who may help to predict the response to treatment by analyzing the expression of targeted proteins in biopsy samples. Precancerous lesions remain a controversial topic and, similarly to other organs, it is acceptable to use the terms "dysplasia" or "squamous intraepithelial lesion" (SIL), but there is a slight difference between low-grade dysplasia and low-grade SIL: in the former, mild atypia must be present, while the latter also includes hyperplastic epithelium without atypia. Two approaches have been proposed: a two-tiered system with low- and high-grade dysplasia/SIL and a three-tiered system with an additional category, carcinoma in situ. We are still searching for reliable diagnostic markers to surpass the subjectivity in biopsy diagnosis, with a few potential candidate markers on the horizon, e.g., stem cell markers. Other tumors are rare at these locations, e.g., hematolymphoid, neuroendocrine and salivary gland neoplasms, and are no longer included in Chapter 3. They must be diagnosed according to criteria described in specific chapters. The same holds true for soft tissue tumors, with the exception of cartilaginous neoplasms, which are still included in Chapter 3.

Abstract
This review gives a brief history of the development of head and neck pathology in Europe from a humble beginning in the 1930s to the explosive activities the last 15 years. During the decades before the introduction of immunohistochemistry in the 1980s, head and neck pathology grew as a subspeciality in many European countries. In the late 1940s, the Institute of Laryngology and Otology with its own pathology laboratory was founded in London, and in 1964 the World Health Organization (WHO) International Reference Centre for the Histological Classification of Salivary Tumours was established at the Bland-Sutton Institute of Pathology, also in London. International collaboration, and very much so in Europe, led to the publication of the first WHO Classification of Salivary Gland Tumours in 1972. In the 1960s, a salivary gland register was organised in Hamburg and in Cologne the microlaryngoscopy was invented enabling microscopic endoscopic examination and rather shortly afterwards a carbon dioxide laser attached to the microscope became established and laryngeal lesions could be treated by laser vaporisation. During the last three decades, the use of immunohistochemistry supplemented with cytogenetic and refined molecular techniques has greatly facilitated the pathological diagnostics of head and neck lesions and has had a huge impact on research. Collaboration between different European centres has drastically increased partly due to establishment of scientific societies such as the Head and Neck Working Group (HNWG) within the European Society of Pathology and the International Head and Neck Scientific Group (IHNSG). A very large number of European pathologists have contributed to the 2nd, 3rd and 4th WHO books, and are involved in the upcoming 5th edition. Accredited educational meetings and courses are nowadays regularly arranged in Europe. Numerous textbooks on head and neck pathology have been written and edited by European pathologists. The increased collaboration has created larger series of tumours for research and new entities, mainly defined by their genetic abnormalities, are continuously emerging from Europe, particularly regarding salivary gland neoplasms and "undifferentiated" sinonasal tumours. These findings have led to a better and more precise classification and open the possibilities for new treatment strategies.

Abstract
Over the past few decades, several publications have investigated the role of Epstein-Barr virus (EBV) in head and neck squamous cell carcinomas, and an increasing number of them have shown its presence in laryngeal tumors. The purpose of this meta-analysis was to evaluate the association of EBV with laryngeal carcinoma. The search was carried out in two databases, Scopus and PubMed, using the following terms: “Epstein-Barr virus” and “laryngeal carcinoma”. A total of 187 records were found, of which 31 were selected for meeting the inclusion and exclusion criteria. The meta-analysis yielded an overall pooled prevalence of 43.72% (95% confidence interval (CI): 34.35–53.08). Studies carried out in Europe and Eurasia had slightly higher pooled prevalence than other subgroups, while the prevalence of studies performed in developed countries was higher than in developing countries (46.37% vs. 34.02%). Furthermore, laryngeal carcinoma occurred almost three times as often among EBV-infected individuals compared to those without EBV infection (odds ratio = 2.86 (95% CI: 1.18–6.90); Begg’s test, p = 0.843 and Egger’s test, p = 0.866). Our findings support the idea that EBV is related to laryngeal carcinoma. However, further studies are needed before recognizing a definitive etiological role of EBV in the development and/or progression of laryngeal carcinomas.

Abstract
PURPOSE To define the oncologic outcomes and the prognostic factors of laryngeal and hypopharyngeal lymphoepithelial carcinoma (LEC). METHODS A systematic review and individual patient data analysis were performed according to the PRISMA guidelines. A total of 41 patients (males: 37; mean age: 63.1, standard deviation: 10.0) were included. RESULTS The median follow-up time was 36.0 months (interquartile range, IQR: 11.5-73.5), while the median overall survival (OS) time was 96 months (IQR: 39.0-120.0). Estimated disease-specific survival (DSS) rates (95% Confidence Interval, CI; number still at risk) at 1, 3, and 5 years were 94.4% (79.5-98.6; 31), 82.7% (62.7-92.5; 21), and 78.1% (56.8-89.7; 13), respectively. Estimated disease-free survival (DFS) rates (95% CI; number still at risk) at 1, 3, and 5 years were 92.1% (77.4-97.4; 31), 74.9% (55.6-86.8; 21), and 66.6% (46.1-80.8; 13), respectively. Patients undergoing primary surgery had a reduced chance of death from cancer than patients receiving primary radiotherapy (5-year DSS 85.6 vs. 56.2%; p = 0.04), while EBV positivity tend to be a negative prognostic factor (5-year DSS 100 vs. 66.7%; p = 0.05). CONCLUSIONS Laryngeal and hypopharyngeal LEC is a rare disease with favorable survival. Further prospective multicenter studies are needed to make a reliable statement on prognosis and outcome, stratifying patients for different therapy regimens and tumor stages.

Abstract
Tumour infiltrating lymphocytes (TILs) have been described as a biomarker for the host immune response against the tumour with prognostic properties. The International Immuno-Oncology Biomarkers Working Group (IBWG) proposed a standardised method for quantifying TILs in solid tumours to improve consistent and reproducible scoring. In this study, the methodology was tested in a retrospective population of oropharyngeal squamous cell carcinoma (OPSCC). TIL quantification was performed on 92 OPSCC samples (2004-2013) by four independent observers as described by the IBWG. Interobserver variability was assessed and results were correlated with clinicopathological variables and survival. TIL evaluation turned out to be challenging in OPSCC due to heterogeneity of TILs distribution, presence of pre-existing lymphoid tissue, surface ulceration or erosion and insufficient amount of intertumoural stroma in biopsies. Nonetheless, interobserver variability proved to be good to excellent. High stromal TILs (TILstr) and intratumoural TILs (TILtum) were both correlated to favourable overall survival and multivariate analysis showed TILstr to be the sole independent prognostic factor in OPSCC. The IBWG-proposed TIL quantification method is feasible and reproducible in OPSCC and provides valuable prognostic information regarding clinicopathological characteristics and overall survival. The use of this standardised methodology may facilitate implementation of TILs scoring as a prognostic biomarker in OPSCC.

Abstract
Background The purpose of this study was to elucidate the clinicopathological characteristics of patients with lymphoepithelial carcinoma of salivary gland (LEC-SG) and determine the factors associated with survival. Methods A total of 179 LEC-SG patients from the Surveillance, Epidemiology, and End Results (SEER) database between 1975 to 2016 were included. The clinicopathological characteristics and overall survival of LEC-SG patients were described, and the features affecting prognosis were further determined using Kaplan-Meier Curves and Cox survival analysis. Results The median overall survival of LEC-SG patients was 206 months, and the 1-, 5-, 10- and 20-year survival rates were 91.0%, 80.2%, 66.4%, and 37.6%, respectively. The prognoses were significantly associated with age, ethnicity, marital status, tumor invasion, as well as lymph node metastases [P<0.01 for all). Surgical resection could significantly improve the prognosis of this disease (median overall survival (mOS): 219 vs. 68 months, P<0.01]. Postoperative radiotherapy could improve long-term survival and decrease the risk of death among patients who survive exceed 10-year after surgery. The Cox regression analysis showed that old age (>60 years) and lymph node metastases were independently associated with poor survival (P<0.05 for both). Conversely, the use of surgery was an independent favorable prognostic factor [hazard ratio (HR) 0.29, 95% CI: 0.13-0.66]. Conclusions LEC-SG patients had a favorable prognosis with a mOS of 206 months. Old age, lymph node metastases, the use of surgery were independently associated with survival of LEC-SG patients.

Cancers (Basel) 2020; 12:cancers12092431. [PMID: 32867094 PMCID: PMC7565469 DOI: 10.3390/cancers12092431] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 08/24/2020] [Accepted: 08/25/2020] [Indexed: 12/05/2022] Open
Abstract
(1) Background: Lymphoepithelial carcinoma of the hypopharynx and larynx is a rare tumor with fewer than 50 cases in the published literature. We present a literature review to discuss the clinical findings, viral or genetic associations, diagnostic challenges, histopathological findings and therapeutic aspects of the disease. (2) Methods: A comprehensive literature review was performed through MEDLINE/PubMed from 1968 to 2018. We identified 21 studies comprising 46 patients. Data on all the clinicopathological features, diagnostic modalities, treatment options and viral or genetic etiology were extracted and analyzed using SPSS. (3) Results: The mean age of presentation was 64 years (range 40–82 years) and mostly involved males. The supraglottis and pyriform sinus were the most commonly involved sub-sites, with surgery as the preferred treatment modality. The presence of the Epstein–Barr virus possibly directs a viral etiology. The incidence of cervical and distant metastasis was 54% and 21%, respectively. The median survival time was 30 months. (4) Conclusions: Lymphoepithelial carcinoma of the hypopharynx is an aggressive tumor with a strong predilection for regional and distant metastasis. Surgery, in combination with adjuvant therapy, provides promising results. Immunohistochemistry helps in differentiating LEC from other pathologies.

Abstract
Laryngeal and hypopharyngeal carcinomas are common malignant tumors of the head and neck, and the incidence of both is increasing. Laryngopharyngeal reflux refers to the retrograde flow of gastric contents into the larynx, oropharynx, and/or nasopharynx. It remains controversial whether laryngopharyngeal reflux is a risk factor for laryngeal and hypopharyngeal cancers. The refluxing substances mainly include hydrochloric acid, pepsin, and occasionally bile acids and bile salts, as well as bacteria that colonize the gastrointestinal tract. Loss of epithelium in the mucous membrane of the larynx and hypopharynx is thought to be caused by pepsin. Here, we review the relationships between laryngopharyngeal reflux and both laryngeal and hypopharyngeal carcinomas, as well as the significance of pepsin, methods of clinical detection, and the mechanism of carcinogenesis.

Abstract
Lymphoepithelial carcinoma of the larynx is a rare tumor, as this histological entity is mostly diagnosed in nasopharynx. However, it may be present in other non-nasopharyngeal sites and it is extremely rare in the larynx. The authors present a case of a 59-year-old man who presented to the Otorhinolaryngology-Head and Neck Surgery Department complaining of a long-standing dysphonia, odynophagia, and dysphagia. The clinical examination revealed a laryngeal tumor involving the right epiglottis, right aryepiglottic fold, and ipsilateral false vocal fold. It presented with ispilateral neck lymph node extension. Multiple biopsies of the laryngeal lesion were performed under local anesthesia and the histological examination showed a poorly differentiated squamous cell carcinoma. After discussing the case in a multidisciplinary tumor board, a total laryngectomy with a bilateral neck dissection was performed and the histological specimen showed a lymphoepithelial carcinoma. Although immunostaining with LMP-1 antibody was negative, in situ hybridization for Epstein-Barr virus was positive. He underwent adjuvant chemoradiation. He is now at 9-months follow-up period, with no evidence of disease. Lymphoepithelial carcinoma of the larynx is an extremely rare disease, with an aggressive pattern. Epstein-Barr virus-associated lymphoepithelial carcinoma has been exceptionally reported. A correct diagnosis and close collaboration with pathologist is crucial to achieve the best treatment strategy. We present this case to discuss the clinical and histology findings and the different therapeutic aspects of this uncommon histological subtype carcinoma.
