Abstract
Among the 16,000 new cases of malignant tumors of the head and neck diagnosed in France each year, 10% are not conventional squamous cell carcinomas. These so-called rare cancers are distinguished by their presentation and patterns of failure, which is important to recognize in order to offer specific adapted management and maximize the chances of tumor control. These cancers can be rare by their histology, which determines their local invasiveness, and their hematogenous/nodal spread. Their diagnosis can be difficult and often requires comprehensive immunohistochemistry and genomic techniques. Expert pathology review is recommended in the cases of undifferentiated tumors, sarcomas and at the slightest diagnostic doubt. These rare cancers can also be rare by their anatomical location when arising from the paranasal sinuses, salivary glands and ear. Their location requires knowledge of their specific extension routes, and may call for a specific surgical technique (skull base endoscopic sinus surgery, extended total parotidectomy, etc.) and adapted radiotherapy to spare healthy organs surrounding the tumor. This article (part 1) discusses the diagnostic and therapeutic specificities of these rare cancers, and develops the recommendations of the French ENT Cancer Expertise Network (REFCOR) concerning rare epithelial tumors, i.e., salivary tumors, sinonasal tumors, variants of conventional squamous cell carcinomas, neuroendocrine carcinomas, malignant odontogenic tumors, and ear tumors. A second article (part 2) is focused on non-epithelial tumors (sarcomas, mucosal melanomas, lymphomas, tumors of uncertain or undetermined malignancy) and describes the organization and missions of the REFCOR.

Case Rep Otolaryngol 2023; 2023:4217102. [PMID: 37235183 PMCID: PMC10208755 DOI: 10.1155/2023/4217102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 04/26/2023] [Accepted: 05/09/2023] [Indexed: 05/28/2023] Open
Abstract
Background Sinonasal lymphoepithelial carcinoma (SNLEC) is a rare neoplasm, representing less than 1% of all types of carcinomas and approximately 3% of head and neck tumors. It can affect the nasopharynx due to the rich lymphoid tissue present in this region. Clinical SNLEC presentation varies, ranging from asymptomatic to nonspecific sinonasal symptoms. We report a case of SNLEC and review the literature for SNLEC presentation, diagnosis, management options, and outcomes. Case Presentation. A 38-year-old male, medically free, presented to the emergency department complaining of nasal obstruction, right facial numbness, persistent right-sided headache, intermittent orbital pain, and a history of on/off epistaxis. Imaging showed a destructive mass in the right sphenoid sinus extending to different sinuses and infratemporal fossa. Biopsy confirmed the diagnosis of SNLEC, with immunohistochemistry being positive for Epstein-Barr virus (EBV) and CK8/18. Induction chemotherapy was started with three cycles of cisplatin and gemcitabine, followed by concurrent chemoradiation therapy. Conclusion SNLEC is rare, with limited reported cases from around the world. It is mostly seen in adults between their fifth and seventh decades with male predominance. SNLEC is diagnosed using imaging, immunohistochemistry, and EBV testing given its strong association with EBV. Owing to the limited cases, there is no standard approach to treating SNLEC. However, most cases managed with radiation and with and without other modalities showed an excellent response in terms of tumor nonrecurrence.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) with distant metastasis (DM) has poor prognosis. HNSCC has several histological variants with varying characteristics. We investigated the DM rates and prognoses of patients with DM among the HNSCC variants. METHODS We obtained data from 54 722 cases using the Surveillance, Epidemiology, and End Results database. Odds ratios (ORs) for DM and hazard ratios (HRs) for overall survival (OS) were estimated using a logistic regression model and a Cox proportional hazard model, respectively. RESULTS DM rate was the lowest in verrucous carcinoma and the highest in basaloid squamous cell carcinoma (BSCC) (0.2% and 9.4%, respectively). ORs for DM were 3.63 for adenosquamous carcinoma, 6.80 for BSCC, and 3.91 for spindle cell carcinoma (SpCC). SpCC was significantly associated with a poor OS (HR, 1.61). CONCLUSIONS DM rates differed among the HNSCC variants. The prognosis of metastatic SpCC is worse than that of other metastatic HNSCCs.

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
BACKGROUND This study presents a summary of the clinical characteristics of non-nasopharyngeal lymphoepithelial carcinoma (NNPLEC), effects of combined modality treatment and prognostic value of plasma Epstein-Barr virus (EBV) deoxyribonucleic acid (DNA) load, with the aim of providing a reference framework for optimizing treatment practices and outcomes. METHODS Patients with NNPLEC treated by our center between January 2000 and December 2020 were retrospectively reviewed. RESULTS In total, 728 patients were included. The lung was identified as the most common primary tumor site (64.0%), followed by the salivary gland (19.2%). A total of 539 (74.0%) patients underwent surgery, 459 (63.0%) received chemotherapy, and 361 (49.6%) were subjected to radiotherapy. The median follow-up time was 45 months (range, 6-212 months) and 5-year overall survival (OS) was 79.1%. Increased plasma EBV-DNA load of >513.5 copies/mL was predictive of disease progression, with a specificity of 98.1% and a sensitivity of 98.9%. In multivariate Cox analysis, N stage, surgery, and radiotherapy were independent prognostic factors for both OS and PFS. Radiotherapy significantly improves OS in comparison with no radiotherapy group for salivary LEC, while surgery significantly improves OS for pulmonary LEC. CONCLUSION Based on our analysis, surgery and radiotherapy are associated with better OS and PFS for NNPLEC. Radiotherapy could be recommended for salivary LEC, while surgery remains the primary treatment strategy for pulmonary LEC patients. An increased plasma EBV-DNA load of >513.5 copies/mL is strongly predictive of disease progression, supporting the importance of regular evaluation of plasma EBV-DNA as part of the diagnostic routine.

Abstract
Lymphoepithelioma was described in 1921 separately by Regaud and Schmincke as nests of non-keratinizing squamous cells embedded in a lymphoid stroma (Regaud) and isolated transitional cells scattered in lymphoid tissue resembling sarcoma (Schmincke). Lymphoepithelial tumors are the most common lesions of the nasopharynx, although they have also been reported in other localizations, such as the nasal cavity, maxillary sinus, the base of the tongue, parapharyngeal area, tonsils and thymus. Lymphoepithelioma of the larynx is extremely rare. We present a case of a 55-year-old patient treated due to this type of lesion to share our experience in the management of this type of malignancy and contribute to the field of rare laryngeal tumors diagnosis and treatment.

Abstract
BACKGROUND Lymphoepithelioma-like carcinoma (LELC) is a rare and unique subtype of cancer that histologically resembles undifferentiated nasopharyngeal carcinoma (NPC). The population-based analysis of LELC and the optimal treatment remains unclear. MATERIALS AND METHODS This real-world, retrospective study investigated 770 patients with LELC for primary site, treatment, and survival outcomes from 2005 to 2019 from five cancer centres in China. The overall survival (OS) of different subgroups was appraised by log-rank tests and Kaplan-Meier analysis. RESULTS Primary sites LELC included the lung (597 cases, 77.5%), salivary gland (115 cases, 14.9%), and others. The median progression-free survival (PFS) of LELC patients was 47.4 months. The median overall survival (OS) was not reached. The 5-year survival rate for LELC patients was 77.8%. Most patients in stages I and II received surgery. The majority of patients in stage III received surgery and radiotherapy. More than half of the patients in stage IV received chemotherapy. Among relapsed or metastatic cases receiving chemotherapy, patients who received immunotherapy at any time presented with a superior OS than those without immunotherapy (P < 0.0001, HR = 0.39, 95% CI 0.25-0.63). Compared with the SEER database, patients with LELC had a better prognosis than NPC, with a 5-year overall survival of 77.3% vs. 56.8% (P < 0.001). CONCLUSION Our data provide treatment patterns and outcomes for LELC from various primary sites. Randomized controlled studies are necessary to further define the standard of care for patients with LELC. Trial registration This clinical trial was registered at ClinicalTrials.gov (No. NCT04614818).

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
Lymphoepithelial carcinoma (LEC) of the larynx is an extremely rare tumour which, unlike its nasopharyngeal counterpart, has shown a propensity to affect elderly Caucasian men and is not commonly associated with Epstein-Barr virus. We present a 70-year-old Chinese man who complained of hoarseness and dysphagia. Nasoendoscopy revealed a left supraglottic tumour. Preoperative MRI (in particular Diffusion Weighted Imaging) showed the possibility of two distinct components within a tumour. The patient underwent total pharyngolaryngectomy and bilateral selective neck dissection. The final histology report confirmed the presence of a tumour with two distinct components: predominant LEC with a smaller conventional (keratinising) squamous cell carcinoma component. The patient recovered well after surgery and subsequently underwent adjuvant radiotherapy. Final staging was pT3 N2c M0 (AJCC stage IVA). Follow-up over 2 years revealed no tumour recurrence.

IMP3 Protein Overexpression Is Linked to Unfavorable Outcome in Laryngeal Squamous Cell Carcinoma. Cancers (Basel) 2021; 13:cancers13174306. [PMID: 34503117 PMCID: PMC8430545 DOI: 10.3390/cancers13174306] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/23/2021] [Accepted: 08/23/2021] [Indexed: 02/02/2023] Open
Abstract
Simple Summary IMP3 expression was analyzed in patients with malignant (laryngeal squamous cell carcinoma), semi-malignant (dysplasia) and benign (nodules, polyps) laryngeal lesions and correlated with clinical characteristics. Higher IMP3 stains were particularly found in malignant laryngeal pathologies, which might be useful for differentiation between premalignant and malignant lesions. In laryngeal cancer patients, higher IMP3 expression was associated with positive neck nodes and worse disease-specific survival. Abstract Background: The aim of this study was to (i) determine IMP3 protein expression in benign and malignant laryngeal lesions, (ii) compare its expression to Ki-67, p53, cyclin D1, and (iii) finally, to examine the prognostic power of IMP3 in squamous cell carcinomas of the larynx (LSSC). Methods: IMP3 protein expression was evaluated in 145 patients, including 62 LSCC, 45 dysplasia (25 with low and 20 with high-grade dysplasia), and 38 benign lesions (vocal cord polyps and nodules). Results: IMP3 was significantly higher expressed in LSCC compared to dysplasia and benign lesions (p < 0.001; p < 0.001, respectively). Similarly, higher expression patterns were observed for Ki-67 and p53, whereas cyclin D1 was equally distributed in all three lesions. IMP3 (p = 0.04) and Ki-67 (p = 0.02) expressions were significantly linked to neck node positivity, and IMP3 overexpression to worse disease-specific survival (p = 0.027). Conclusion: Since IMP3 showed significantly higher expression in laryngeal carcinomas, but not in high- or low-grade dysplasia, it serves as a useful marker to differentiate between invasive and noninvasive lesions. Higher IMP3 expression represented a significantly worse prognosticator for clinical outcomes of patients with squamous cell carcinoma of the larynx.

Abstract
Lymphoepithelial carcinoma (LEC) is an uncommon, aggressive cancer that affects mainly the nasopharynx (a form that is closely related to the Epstein-Barr virus). LEC of the larynx/hypopharynx is extremely rare, accounting for only 0.2% of malignant tumors of the larynx. This study describes a case of locally advanced LEC of the larynx/hypopharynx with effective response to chemoradiation (an option that spares the patient from the risks of surgical resection). A 60-year-old sedentary, hypertensive male patient with a previous history of smoking and alcohol abuse received a histopathological diagnosis of locally advanced LEC of the larynx/hypopharynx in May 2018. He underwent treatment with chemoradiation and exhibited a complete clinical response. At about 3 years of follow-up, the patient is currently alive, free from disease and has not presented any tumor recurrences.
