Head neck carcinomas

Bayardo Perez-Ordoñez
Primary neuroendocrine carcinomas (NECs) of the larynx and head and neck are an uncommon and heterogeneous group of neoplasms categorized by the 2017 WHO Classification of Head and Neck Tumors as: (a) well-differentiated (WD-NEC), (b) moderately-differentiated (MD-NEC), and (c) poorly-differentiated (PD-NEC) with small cell and large cell types. The classification incorporates elements of differentiation and grading and closely correlates to the 5-year disease specific survival of 100, 52.8, 19.3 and 15.3% for each diagnostic category...

Human papillomavirus (HPV)-related head and neck carcinoma (HNC) represents an important subgroup of head and neck cancer that is characterized by a consistent microscopic appearance and a favorable prognosis. A growing experience with HPV testing, however, has uncovered variants that deviate from the prototypic HPV-HNC with respect to morphology. While these HPV-HNCs may deviate morphologically from the prototype, they do not appear to stray far from the favorable clinical outcome assigned to HPV-positive status...

Salivary neuroendocrine carcinomas are rare and the overwhelming majority is high-grade. The parotid gland is the most commonly involved site followed by the submandibular gland. Most arise de novo but rare examples occurring as a high-grade transformation of another type of salivary gland neoplasm exist. There is significant morphologic and immunophenotypic overlap with neuroendocrine carcinomas of other sites, especially the skin. Like cutaneous neuroendocrine (or Merkel cell) carcinomas, approximately three-fourths are cytokeratin 20 positive...

Radiotherapy alone, or as an addition to surgery is important for the treatment of head and neck squamous cell carcinoma (HNSCC). In addition to their expression in germ cells, melanoma associated antigens-A (MAGE-A) are only expressed in malignant tissue. Notably, there is a known correlation between MAGE-A9 expression and poor prognosis in HNSCC patients. However, current knowledge regarding the function of MAGE-A9 expression, particularly in the context of irradiation, is limited. MAGE-A9 expression in 37 oral squamous cell carcinoma patents was immunohistochemically determined and analyzed for overall survival by the Kaplan-Meier log-rank test...

Over 70% of head & neck squamous cell carcinoma (HNSCC) patients carry TP53 oncogenic mutations. Here we studied the role of specific tumor-derived mutant p53 proteins in the aberrant transcription of long non-coding (lnc) MIR205HG gene in head and neck cancer cells. Methods: To understand the role of lncMIR205HG, that we showed to be transcriptionally regulated by mutant p53 in HNSCC, we have employed siRNA and shRNA in CAL27 and FaDu HNSCC cell lines to suppress p53 gene expression in ChIP assays and RT-qPCR...

Rationale: Nasopharyngeal carcinoma (NPC) is the most frequent head and neck tumor in South China. The presence of cancer stem cells (CSCs) in NPC contributes to tumor maintenance and therapeutic resistance, while the ability of CSCs to escape from the apoptosis pathway may render them the resistant property to the therapies. Inhibitor of apoptosis proteins family proteins (IAPs), which are overexpressed in nasopharyngeal carcinoma stem cells, may play an important role in maintaining nasopharyngeal cancer stem cell properties...

Bleomycin (BLM) is an antibiotic isolated from Streptomyces verticillus. It has radiomimetic actions on DNA thus it has been widely used in clinical chemotherapy for the treatment of different types of cancer, including head and neck tumors, lymphomas, squamous-cell carcinomas and germ-cell tumors. Because of this, the study of BLM genotoxicity is of practical interest. This antibiotic is an S-independent clastogen and an agent that generates free radicals and induces single- and double-strand breaks in DNA...

PURPOSE: Most primary tumors spreading metastasis to the parotid gland are usually located in the head and neck region, nonetheless, rarely, parotid gland can also be the target of metastatic localization site of distant primary tumors. The purpose of this study was to describe a clinical series of metastasis to the parotid gland from distant primary tumors (non Head & Neck). METHODS: The clinical databases of parotid tumors in two academic centers have been analyzed and 11 cases of parotid metastatic cancers from distant primary tumors were found...

Human papillomavirus (HPV)-mediated cervical carcinogenesis represents a well analyzed model of viral implication in epithelial malignant transformation. Mechanisms of high risk (HR) HPV-related infection seem to demonstrate a similar action regarding its implication in head and neck (HN) carcinomas, predominantly in squamous cell carcinoma (SCC) histological type. The prevalence of HR HPV subtypes - mainly HPV16 - is characterized by a broad geographic heterogeneity. Furthermore, HPV-associated HNSCCs demonstrate differences regarding sexual, molecular, epidemiological, and prognostic features compared to alcohol and tobacco dependent ones...

Objectives: Management of neck metastases in terms of diagnosis and treatment has always been a controversial issue in patients of head and neck malignancy. The main area of debate in case of diagnosis lies with the fact that whether we should rely on ultrasound, as a diagnostic modality for diagnosing micrometastases in the neck in head and neck malignancy patients? The second controversial issue is the management of N0 neck, whether to be radical or conservative? Materials and Methods: This study was conducted on 70 diagnosed patients of head and neck carcinoma who were planned for resection of the primary...

The Epidermal Growth Factor Receptor (EGFR) is selectively expressed on the surface of numerous tumours, such as non-small cell lung, ovarian, colorectal and head and neck carcinomas. EGFR has therefore become a target for cancer therapy. Cetuximab is a chimeric human/mouse monoclonal antibody (mAb) that binds to EGFR, where it both inhibits signaling and induces cell death by antibody-dependent cell mediated cytotoxicity (ADCC). Cetuximab has been approved for clinical use in patients with head and neck squamous cell carcinoma (HNSCC) and colorectal cancer...

Metastases to the parotid gland are the commonest cause of parotid malignancies in many regions of the world including Australia. The most common etiology of these metastases is head and neck cutaneous squamous cell carcinoma (HNcSCC) followed by melanoma of the head and neck. This article focuses on the management of the aforementioned pathologies including Merkel cell carcinoma (MCC).

A 70-year-old Japanese man with recurrent squamous cell carcinoma of the head and neck presented with severe interstitial pneumonia associated with nivolumab, after talc slurry pleurodesis. Following the development of malignant pleural effusion, he underwent chest drainage and was administered intrathoracic talc as a pleurodesis. Two weeks later, we administered nivolumab (3mg/kg) to be repeated every 2 weeks. However, on day 12, chest computed tomography scan demonstrated diffuse non-segmental ground-glass opacity and mild bronchiectasis...

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...

Human Papilloma Virus (HPV) can play a causative role in the development of sinonasal tract malignancies. In fact, HPV may be the most significant causative agent implicated in sinonasal tumorigenesis and is implicated in as many as 21% of sinonasal carcinomas. To date, there are no definitive, reliable and cost-effective, diagnostic tests approved by the FDA for the unequivocal determination of HPV status in head and neck cancers. We followed an exhaustive algorithm to correctly test HPV infection, including a sequential approach with p16INK4a IHC, viral DNA genotyping and in situ hybridization for E6/E7 mRNA...

Angiosarcoma is a rare vascular soft tissue tumor of endothelial origin most commonly seen in the elderly as a primary cutaneous head and neck malignancy. Furthermore, a peritoneal angiosarcoma is an exceedingly rare entity. This is the second case of primary peritoneal angiosarcoma reported in literature that is not associated with prior radiotherapy. Herein, we describe a case of primary peritoneal angiosarcoma metastatic to both the liver and bone in a male patient with metachronous renal cell carcinoma and parathyroid adenoma...
