Purpose: We previously demonstrated an association between decreased SMAD4 expression and cetuximab resistance in head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to further elucidate the clinical relevance of SMAD4 loss in HNSCC. Experimental Design: SMAD4 expression was assessed by immunohistochemistry in 130 newly diagnosed and 43 recurrent HNSCC patients. Correlative statistical analysis with clinicopathological data was also performed. OncoFinder, a bioinformatics tool, was used to analyze molecular signaling in TCGA tumors with low or high SMAD4 mRNA levels...

Histatins are multifunctional histidine-rich peptides secreted by the salivary glands and exclusively present in the saliva of higher primates, where they play a fundamental role in the protection of the oral cavity. Our previously published results demonstrated that histatin-1 (Hst1) promotes cell-substrate adhesion in various cell types and hinted that it could also be involved in cell-cell adhesion, a process of fundamental importance to epithelial and endothelial barriers. Here we explore the effects of Hst1 on cellular barrier function...

Normal tissue damage after head and neck radiotherapy involves a continuum of pathologic events to the mucosa, tongue and salivary glands. We examined the radioprotective effects of MnBuOE, a redox-active manganese porphyrin, at three stages of normal tissue damage: immediate (leukocyte endothelial cell [L/E] interactions), early (mucositis) and late (xerostomia and fibrosis) after treatment. In this study, mice received 0 or 9 Gy irradiation to the oral cavity and salivary glands ± MnBuOE treatment. Changes in leukocyte-endothelial cell interactions were measured 24 h postirradiation...

Vaginal cuff dehiscence is a rare but serious complication that can develop after hysterectomy. Emergent surgical intervention is required for vaginal cuff dehiscence due to the potential subsequent vaginal evisceration, which may lead to necrosis of the small bowel. A 62-year-old nulliparous woman with a 30-year history of smoking, diabetes mellitus, and rheumatoid arthritis (treated with oral steroids) presented with a vaginal cuff dehiscence. Thirty-eight days before the admission, she had undergone a radical operation including total abdominal hysterectomy for uterine corpus cancer at another hospital...

BACKGROUND: Leukaemia represents 30-40% of all paediatric malignant tumours and is the main cause of death in patients aged <15 years. One of the main complications in these patients is infection, which may often occur in the oral cavity. Chemotherapy-related oral health problems may be reduced by oral healthcare strategies based on the International Caries Detection and Assessment System (ICDAS) and Caries Management by Risk Assessment (CABRA). CASE REPORT: A case is reported of a 14-year-old girl treated for leukaemia who presented with established dental caries lesions which were classified and treated according to ICDAS and CABRA protocols...

Head and neck squamous cell carcinoma is the sixth most common cancer diagnosed worldwide and the eighth most common cause of cancer death. Malignant tumors of the oral cavity, oropharynx, and larynx can be treated by surgical resection or radiotheraphy with or without chemotheraphy and have a profound impact on quality of life functions, including swallowing. When surgery is the chosen treatment modality, the patient may experience swallowing impairment in the oral and pharyngeal phases of deglutition. A videofluoroscopic study of swallow enables the morphodynamics of the pharyngeal-esophageal tract to be accurately examined in patients with prior surgery...

Osteonecrosis of the jaw (ONJ) is a rare treatment related side effect that was firstly described in 2002 through a case report in metastatic bone cancer patient treated with bisphosphonates (BPs) therapy. ONJ is defined as an eight weeks or longer clinical finding of exposed bone in the oral cavity without response to appropriate therapy. The diagnosis is mainly clinical but often requires a radiological confirmation with an orthopantomography. So it must be made by a dental specialist with sufficient experience on ONJ and requires a detailed anamnestic exploration of comorbidities and treatments history...

Metastatic tumors rarely occur in the oral cavity. The most common of the oral metastases are lung cancers in males, and breast and genital cancers in females. The most common primary tumor metastasis to the oral cavity is from the lung, kidney, liver, prostate, and colorectal cancers. The metastatic lesions are similar to oral lesions such as pyogenic granuloma, giant cell lesions, gingival polyps, hemangioma, peripheral fibroma, and adenoid squamous cell carcinoma. Therefore, the diagnosis of primary tumors is challenging...

PURPOSE: Surgery, chemo- and/or external radiation therapy are the standard therapy options for the treatment of laryngeal cancer. Trans-oral access for the surgery reduces traumata and hospitalization time. A new trend in treatment is organ-preserving surgery. To avoid regrowth of cancer, this type of surgery can be combined with radiation therapy. Since external radiation includes healthy tissue surrounding the cancerous zone, a local and direct intraoral radiation delivery would be beneficial...

BACKGROUND: Squamous cell carcinomas (SCCs) are the most prevalent malignant tumours within the head and neck. Evidence exists that distinct genes are differentially regulated in SCCs of the oral cavity compared to other head and neck regions. Given this background, the aim of this study was to investigate whether such tumour site-specific gene expression can also be observed in different localizations within the oral cavity. METHODS: Using tissue microarrays (TMAs), we investigated 76 SCCs of the floor of the mouth, 49 SCCs of the tongue and 68 SCCs of other anatomic regions within the oral cavity...

Oral cavity and pharynx cancer, even when considered together, is a fairly rare disease. Implementation of multivariate modeling with lung and bronchus cancer, as well as melanoma cancer of the skin, could lead to better inference for oral cavity and pharynx cancer. The multivariate structure of these models is accomplished via the use of shared random effects, as well as other multivariate prior distributions. The results in this paper indicate that care should be taken when executing these types of models, and that multivariate mixture models may not always be the ideal option, depending on the data of interest...
