MicroRNAs (miRNAs) are confirmed to be tumor promoters or suppressors in multiple squamous cell carcinomas (SCCs). miR-99a-5p has been demonstrated to be downregulated in cancerous tissues, but its functional role in head and neck SCC (HNSCC) and its mechanism of action have not been fully elucidated. Here, we studied the expression of miR-99a-5p in HNSCC and performed a clinical value assessment and then extracted mature expression data from The Cancer Genome Atlas (TCGA) and microarrays from Gene Expression Omnibus (GEO)...

Malignant neoplasms may be composed of several cell groups, including cancer stem cells (CSC). These cells have been related with the capacity of metastasis, relapse and resistance to multiple drugs during chemotherapy. This study aims to identify CSC biomarkers and their expression pattern in human head and neck carcinomas. This study was conducted following the PRISMA checklist. The search for articles was carried out in five databases (PubMed, Scopus, Web of Science, Lilacs and Scielo). The articles found were selected in two phases: 1) reading the titles and / or abstract and 2) reading the full text...

Background: Head and neck (H&N) cancers account for about 5% of all malignant tumours. Pain is one of the most feared consequences of H&N neoplasms and is experienced by up to 80% of patients and worsens their quality of life inhibiting speaking, eating, drinking or swallowing. Nevertheless, pain is still often underestimated and undertreated. Objectives: The role of opioids in cancer pain has been well established but evidences about the role and the relative effectiveness of opioids such as fentanyl in the context of H&N cancer pain remains unclear...

5-Fluorouracil (5-FU) is used in combination chemotherapy protocols for human head and neck cancer and other epithelial neoplasms. However, a paucity of literature describing use of this drug in veterinary oncology exists, likely due to previous reports of fatal neurotoxicity in both dogs and cats, mainly due to ingestion of human creams. The primary aim of this retrospective study was to report the safety of concurrent 5-FU and carboplatin in canine carcinomas. Secondarily, we aimed to look at the efficacy of the combination using overall response rate in treated dogs...

Adenoid cystic carcinoma (ACC) is an uncommon malignant neoplasm composed of basaloid epithelial and myoepithelial cells. The palate is the most commonly involved intraoral site for ACC. Here, we document the case of an advanced ACC arising from the hard palate that presented with right-sided sixth nerve palsy in a 75-year-old male with no other systemic illnesses. ACC of the head and neck involving the cavernous sinus and presenting as isolated sixth nerve palsy is exceedingly rare. In the absence of vasculopathic or ischemic risk factors, regardless of the age of the patient; neuroimaging should be performed in cases of isolated nontraumatic sixth nerve palsy...

Translational cancer research has benefitted significantly from the generation of preclinical models that recapitulate the native tumour environment. While conventional cell models have contributed substantially to the current understanding of cancer biology and therapeutic development, a missing link between cell culture and their clinical applications is evident. Patient derived xenograft (PDX) models represent this missing link as they enable the examination of patient tumour tissue in a native environment without significantly affecting the cellular complexity, genomics, and stromal architecture of the neoplasms...

BACKGROUND: The designation Rabdomyosarcoma (RMS) is used to describe the malignant mesenchymal neoplasm that exhibits varying degree of skeletal muscle differentiation. RMS is the commonest malignancy of soft tissues afflicting children and adolescent up until age 20. It constitutes 5-10% of pediatric malignancies, and 7-9.5% of pediatric soft tissue sarcomas. The site of origin of RMS can be one of three possibilities: myogenous; extramyogenous; and ectopic (heterotopia). This was a retrospective study of consecutive cases of RMS seen at the Histopathology Department of the Jos University Teaching Hospital, Jos, between January 2007 and December 2016...

Importance: Second primary malignant neoplasms (SPMNs) are the leading cause of death in survivors of head and neck squamous cell carcinoma (HNSCC). Recently, human papillomavirus (HPV) has emerged as a risk factor for oropharyngeal squamous cell carcinoma and has different prognosis from classic tobacco/alcohol-associated HNSCC. This suggests that there also may be different risks and burden of SPMNs among patients who's HNSCC were from HPV or tobacco and/or alcohol. Objective: To assess SPMN risks and burden in a large US cohort of patients with a first potentially HPV-associated HNSCC vs non-HPV-associated HNSCC...

Giant-cell tumor of soft tissue (GCT-ST) is a rare neoplasm that was first described in 1972. Due to its histological and immune-histochemical similarities with GCT of bones, GCT-ST is thought to be its counterpart. This review article aims to recognize the characteristics of this rare tumor along with a favorable way to diagnose and treat. We reviewed 12 cases of GCT-ST in the head and neck. This tumor involves both sexes at any age. Histopathology in many cases revealed the presence of mononuclear cells and spindle cells...

Extramedullary plasmacytoma (EP) is a rare neoplasm characterized by monoclonal proliferation of plasma cells without features of multiple myeloma. EP constitutes 3% of all plasma cell tumors. Most of the cases of EP occur in the head and neck regions, especially in the aerodigestive tract. We present a case of recurrent epistaxis for 6 months and extensive workup revealed EP of the right nasal cavity. Primary care physicians and otolaryngologists should be aware of this very rare but a plausible cause of epistaxis and keep EP in the differential diagnosis of recurrent epistaxis...

Adipokines constitute a family of protein factors secreted by white adipose tissue (WAT), that regulate the functions of WAT and other sites. Leptin, adiponectin, resistin, are the main adipokines present in serum and saliva, targeting several tissues and organs, including vessels, muscles, liver and pancreas. Besides body mass regulation, adipokines affect glucose homeostasis, inflammation, angiogenesis, cell proliferation and apoptosis, and other crucial cell procedures. Their involvement in tumor formation and growth is well established and deregulation of adipokine and adipokine receptors' expression is observed in several malignancies including those located in the head and neck region...

Hemangiopericytomas (HPCs)/Solitary fibrous tumor are rare neoplasms of vascular origin that occur in head-and-neck region. These tumors arise from capillary pericytes and are difficult to distinguish from other tumors of vascular origin. HPC, initially described by Stout and Murray in 1942, usually occur in the fifth decade of life and account for 3%-5% of all soft-tissue sarcomas and 1% of all vascular tumors. The tumors usually occur in limbs, pelvis, or head-and-neck region; 15%-30% of all HPCs occur in head and neck...
