Cancer occurrence can be understood as the result of dysfunctions in immune tumoral microenvironment. Here we review the recent understandings of those microenvironment changes, regarding their causes and prognostic significance in head and neck (HN) carcinoma. We will focus on HN squamous cell cancer (SCC) and nasopharyngeal carcinomas (NPC). Their overall poor prognosis may be improved with immunotherapy in a subset of patients, as supported by current clinical trials. However, finding reliable markers of therapeutic response is crucial for patient selection, due to potential severe adverse reactions and high costs...

Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV)-associated lymphoepithelioma. The aim of the present study was to characterize the homogeneity and distinctness of the T-cell repertoires within and between primary and metastatic NPCs. We used ultra-deep sequencing of the hypervariably rearranged antigen-binding CDR3 regions of T-cell receptor beta (TCRbeta ) to comprehensively profile the T-cell repertoires in NPC patients receiving definitive chemoradiotherapy with long-term follow-up. We observed not only various spatially heterogeneous patient-specific TCRbeta clone compositions that changed with time but also several commonly enriched TCRbeta subclones that were constantly shared between primary NPCs in the head and neck regions, locally recurrent tumors after treatment, and later-developed distant metastatic tumors in the liver, lung and bone...

Nasopharyngeal carcinoma (NPC) is a head and neck cancer associated with poor prognosis. Many studies have shown that the epithelial-to-mesenchymal transition (EMT) is important in cancer progression, metastasis, and chemotherapy resistance and that microRNAs (miRNAs) play a key role in chemotherapy resistance associated with EMT. The miRNA miR-139-5p is downregulated in many human cancers and is closely related to tumor progression. The aim of this study was to investigate the ability of miR-139-5p to influence the cisplatin resistance, apoptosis, invasion and migration in NPC cells through the regulation of the EMT...

Nasopharyngeal carcinoma (NPC) is one of the most common head and neck malignancies and is typically treated with radiotherapy and chemotherapy. Garcinone C, a natural compound isolated from Garcinia oblongifolia Champ., is a xanthone derivative with potential cytotoxic effects on certain cancers. However, there are limited studies regarding its effects on NPC cells, and its mechanism of action in NPC remains unknown. In the present study, we found that garcinone C significantly inhibited cell viability of the human NPC cell lines CNE1, CNE2, HK1 and HONE1...

Nasopharyngeal carcinoma (NPC) is an epithelial malignancy, which is notorious among head-and-neck cancers with its metastatic feature. Epstein-Barr virus (EBV) infection plays a fundamental role in NPC development with the mechanism is not well understood. Here we demonstrate that EBV oncoprotein LMP1 drives EMT and metastasis of NPC by reactivating the adhesion molecule, cadherin 6 (CDH6), which normally occurs in embryogenesis with unknown role in NPC. CDH6 was found to be upregulated in LMP1-positive NPC tissues, and was identified as a target of the epithelium-specific miR-203...

Head and neck cancers are among the most frequently occurring cancers worldwide. Of the molecular drivers described for these tumors, galectins play an important role via their interaction with several intracellular pathways. In this review, we will detail and discuss this role with specific reference to galectins-1, -3, and -7 in angiogenesis, cell proliferation, and invasion as well as in cell transformation and cancer progression. Furthermore, we will evaluate the prognostic value of galectin expression in head and neck cancers including those with oral cavity, salivary gland, and nasopharyngeal pathologies...

This article is a continuation of the "Do You Know Your Guidelines" series, initiated by the Education committee of the American Head and Neck Society. Treatment guidelines for advanced head and neck squamous cell carcinoma are reviewed here, including the critical roles of radiotherapy, chemotherapy, and the recent application of immunotherapy agents. We will be limiting this discussion to include cancers of the oral cavity, oropharynx, hypopharynx, and larynx. It should be noted that much of the article pertains to human papillomavirus (HPV)-negative oropharyngeal cancer where applicable, as HPV-positive oropharyngeal squamous cell carcinoma carries a different natural history, different prognosis, and now different staging criteria...

PURPOSE: Nasopharyngeal carcinoma (NPC) is most common head and neck cancer in Southeast Asia. Because local recurrence and distant metastasis are still the main causes of NPC treatment failure, it is urgent to identify new tumor markers and therapeutic targets for advanced NPC. EXPERIMENTAL DESIGN: RNA-seq was applied to look for interchromosome translocation in NPC. PCR, FISH and immunoprecipitation were used to examine the fusion gene expression at RNA, DNA, and protein levels in NPC biopsies...

INTRODUCTION: Definitive treatment of nasopharyngeal carcinoma (NPC) is challenging owing to its rarity, complicated regional anatomy, and the intensity of therapy. In contrast to other head and neck cancers, the effect of facility volume has not been well described for NPC. METHODS AND MATERIALS: The National Cancer Database was queried for patients with stage II-IVB NPC diagnosed from 2004 to 2014 and treated with definitive radiation. Patients with incomplete staging, unknown receipt or timing of treatment, unknown follow-up duration, incomplete socioeconomic information, or treatment outside the reporting facility were excluded...

Nasopharyngeal carcinoma (NPC) is distinct from other cancers of the head and neck in biology, epidemiology, histology, natural history, and response to treatment. Radiation therapy is an essential component of curative-intent of non-disseminated disease and the association of chemotherapy improves the rates of survival. In the case of metastatic disease stages, treatment requires platinum/gemcitabine-based chemotherapy and patients may achieve a long survival time.
