BACKGROUND: 18 FDG PET/CT is crucial before neck surgery for nodal recurrence localization in iodine-refractory differentiated or poorly differentiated thyroid cancer (DTC/PDTC). A dedicated head-and-neck (HN) acquisition performed with a thin matrix and point-spread-function (PSF) modelling in addition to the whole-body PET study has been shown to improve the detection of small cancer deposits. Different protocols have been reported with various acquisition times of HN PET/CT. We aimed to compare two reconstruction algorithms for disease detection and to determine the optimal acquisition time per bed position using the Siemens Biograph6 with extended field-of-view...

Neutrophil extracellular traps (NETs) promote cancer metastasis in preclinical models following massive exogenous inflammatory stimuli. It remains unknown whether cancer hosts under physiologic conditions experience NETosis and consequent metastasis. Here we show that plasma redox imbalance caused by albumin oxidation promotes inflammation-independent NETosis. Albumin is the major source of free thiol that maintains redox balance. Oxidation of albumin-derived free thiol is sufficient to trigger NETosis via accumulation of reactive oxygen species within neutrophils...

Mechanical remodeling of stromal collagen, such as reorientation and deformation of collagen matrix, generated by invading cancer cells, plays an important role in the progression of cancer invasion and metastasis. In this study, we applied time-lapse microscopy in conjunction with particle displacement mapping to analyze time-dependent contraction and expansion deformations of collagen surrounding individual spheroids of head and neck squamous cell carcinoma cells (HNSCC), OECM-1 & SAS, as the cancer cells detached from the spheroid and invaded into the surrounding 3D collagen matrix...

Standardized, synoptic pathologic reporting for tumors greatly improves communication among clinicians, patients, and researchers, supporting prognostication and comparison about patient outcomes across institutions and countries. The International Collaboration on Cancer Reporting is a nonprofit organization whose mission is to develop evidence-based, universally available surgical pathology reporting data sets. Within the head and neck region, lymph node excisions and neck dissections are frequently performed as part of the management of head and neck cancers arising from the mucosal sites (sinonasal tract, nasopharynx, oropharynx, hypopharynx, oral cavity, and larynx), along with bone tumors, skin cancers, melanomas, and other tumor categories...

Lymph node (LN) dissection is a crucial procedure for cancer staging, diagnosis and treatment and for predicting patient survival. Activation of lung metastatic lesions after LN dissection has been described for head and neck cancer and breast cancer. Preclinical studies have reported that dissection of a tumor-bearing LN is involved in the activation and rapid growth of latent tumor metastases in distant organs, but it is also important to understand how normal (non-tumor-bearing) LN resection influences secondary cancer formation...

Although rare, cutaneous metastases portend a poor prognosis and are often an indicator of widespread disease. Breast cancer and melanoma are the most common types of cancer that are associated with spread to and within the skin; however, other malignancies, such as lung, colon, head and neck, and hematologic, have been described with a degree of relative frequency. A variety of clinical appearances and syndromes of cutaneous metastases are presented and described in this article. Possible treatment options, including skin-directed therapies and immunotherapies, are also discussed...

Head and neck squamous cell carcinomas (HNSCC) preferentially spread to regional cervical tissues and lymph nodes. Here, we hypothesized that lymphotoxin-β (LTβ), receptor LTβR, and NF-κB-inducing kinase (NIK), promote the aberrant activation of alternative NF-κB2/RELB pathway and genes, that enhance migration and invasion of HNSCC. Genomic and expression alterations of the alternative NF-kB pathway were examined in 279 HNSCC tumors from The Cancer Genome Atlas (TCGA) and a panel of HNSCC lines. LTβR is amplified or overexpressed in HNSCC of the larynx or oral cavity, while LTβ, NIK, and RELB are overexpressed in cancers arising within lymphoid oropharyngeal and tonsillar sites...

Cardiac metastasis from head and neck cancers are very rare. Metastases to heart are mostly diagnosed at autopsy, and seldom found while patients are alive. Patients with cardiac metastasis do not present with specific symptoms in the early stages, and diagnosis is often delayed until the disease has advanced significantly. Here, we report a 66-year-old lady who was diagnosed with cardiac metastasis 10 months after surgical resection of oral cancer. She died one month following the discovery of cardiac metastasis...

Enhancer of Zeste homologue 2 (EZH2) overexpression is associated with tumor proliferation, metastasis, and poor prognosis. Targeting and inhibition of EZH2 is a potentially effective therapeutic strategy for head and neck squamous cell carcinoma (HNSCC). We analyzed EZH2 mRNA expression in a well-characterized dataset of 230 (110 original and 120 validation cohorts) human head and neck cancer samples. This study aimed to investigate the effects of inhibiting EZH2, either via RNA interference or via pharmacotherapy, on HNSCC growth...

Mitochondrial dysfunction is caused by an imbalance in the fission and fusion processes, and it has been implicated in the pathogenesis of several human cancers. However, the role of mitochondrial markers in melanomas still remain poorly understood. In this study, the authors assessed the expression of three mitochondrial markers [antimitochondrial (AMT), fission protein 1 (FIS1) and mitofusin 2 (MFN2)] in a series of head and neck mucosal and cutaneous melanomas. Patients with cutaneous (n=56), and mucosal [oral - n=30 and sinonasal - n=26] melanomas of the head and neck region were enrolled in this study...

Human papillomavirus (HPV) is a major causative agent of head and neck squamous cell carcinomas (HNSCC). Over the past several decades, an increasing number of studies established the strong association of HPV with the invasion and metastasis of HNSCC. In the present study, we reviewed the gene mutations in HPV-associated HNSCC and the unique mechanism of E6- and E7-mediated carcinogenesis via interactions with an array of cellular elements. We further discussed the progress in the mechanisms of invasion and metastasis; these mechanisms include non-coding RNAs, deregulating cellular energetics, tumor microenvironment, cancer stem cells, angiogenesis, and lymphangiogenesis...

Background: Deregulated Hippo signaling has been uncovered to be intricately involved in tumorigenesis. Transcriptional factor TEADs serve as key mediators of Hippo signaling and have been increasingly appreciated as putative oncogenes driving cancer initiation and progression. However, its expression pattern and oncogenic role of TEAD4 in head and neck squamous cell carcinoma (HNSCC) remain largely unexplored. Methods: TEAD4 mRNA expression in HNSCC was determined by data mining and analyses from TCGA dataset and four independent cohorts with transcriptional profiling data publically available...

The immune system has a vital role in the development, establishment, and progression of head and neck squamous cell carcinoma (HNSCC). Immune evasion of cancer cells leads to progression of HNSCC. An understanding of this mechanism provides the basis for improved therapies and outcomes for patients. Through the tumor's influence on the microenvironment, the immune system can be exploited to promote metastasis, angiogenesis, and growth. This article provides an overview of the interaction between immune infiltrating cells in the tumor microenvironment, and the immunologic principles related to HNSCC...

Risk factors for metastasis from cutaneous squamous cell carcinoma are incorporated in tumor staging by the seventh edition of the American Joint Committee on Cancer Cancer Staging Manual.We confirmed most risk factors, and also identified moderate differentiation as a predictor for lymph node metastasis. Moderate differentiation can be considered in tumor staging.

CheckMate 141, an open-label, randomized phase III trial of nivolumab, indicated that treatment with nivolumab prolonged overall survival of patients with platinum-refractory, recurrent head and neck squamous cell carcinoma. Herein, we describe a case of brain metastasis of parotid carcinoma in which a good response was achieved after nivolumab treatment. The patient was a 67-year-old woman with parotid carcinoma (cT4bN0M0) who received induction chemotherapy followed by chemoradiation. Computed tomography and magnetic resonance imaging performed 10 weeks after the primary treatment revealed a residual tumor and brain and lung metastases...

Lymph node metastasis (LNM) is a significant prognostic factor in patients with head and neck cancer, and the ability to predict it accurately is essential for treatment optimization. PET and CT imaging are routinely used for LNM identification. However, uncertainties of LNM always exist especially for small size or reactive nodes. Radiomics and deep learning are the two preferred imaging-based strategies for node malignancy prediction. Radiomics models are built based on handcrafted features, and deep learning can learn the features automatically...
