OBJECTIVES: The aim of this study was to analyze the influence of dental treatment on the development of osteoradionecrosis (ORN) of the jaw. METHODS: This study included the data of 776 patients who underwent 3D-CRT or IMRT because of head and neck cancer. Sex, dental status before and after radiotherapy (RT), tumor site, bone surgery during tumor operation, concomitant chemotherapy, and the development of an advanced ORN were documented for each patient. The patients' dentitions before and after RT were classified into four groups with regard to the number and localization of the remaining teeth...

Cancer metastases arise from a multi-step process that requires metastasizing tumor cells to adapt to signaling input from varying tissue environments [1]. As an early metastatic event, cancer cell dissemination occurs through different migration programs, including multicellular, collective, and single-cell mesenchymal or amoeboid migration [2-4]. Migration modes can interconvert based on changes in cell adhesion, cytoskeletal mechanotransduction [5], and/or proteolysis [6], most likely under the control of transcriptional programs such as the epithelial-to-mesenchymal transition (EMT) [7, 8]...

Hypopharyngeal cancer (HPC) is generally a rare head and neck malignancy. There are differing clinical presentations depending on the subsite location of primary tumour. Advanced HPC will have neck node metastasis particularly upper jugulodigastric nodes. We report a patient with postcricoid tumour who presented with anterior huge neck swelling mimic thyroid mass. The patient first presented to the General Surgical Unit for management of presumed thyroid lesion. She was diagnosed post-cricoid squamous cell carcinoma when further assessed by otorhinolaryngologist...

BACKGROUND: False-positive radioiodine (RAI) uptake related to chronic sinusitis and mucocele has only rarely been reported in patients with differentiated thyroid cancer (DTC) even with the recent use of single photon emission tomography with computed tomography (SPECT/CT) acquisition. No other etiology of sinus RAI uptake has been mentioned to date. OBJECTIVES: We report five cases of DTC patients with sinus RAI uptake on post-RAI scintigraphy. SPECT/CT clearly localized RAI uptake either in the sphenoid, the maxillary or the frontal sinus and highly suspected mucosal thickening in four patients and sinus aspergilloma in one patient...

BACKGROUND: Planning and delivery of IMRT for locally advanced head and neck cancer (LAHNC) can be performed using sequential boost or simultaneous integrated boost (SIB). Whether these techniques differ in treatment-related outcomes including survival and acute and late toxicities remain largely unexplored. METHODS: We performed a single institutional retrospective matched cohort analysis on patients with LAHNC treated with definitive chemoradiotherapy to 69.3 Gy in 33 fractions...

Extracellular signal-regulated kinase 3 (ERK3) is an atypical mitogen-activated protein kinase (MAPK), whose biological activity is tightly regulated by its cellular abundance. Recent studies have revealed that ERK3 is upregulated in multiple cancers and promotes cancer cell migration/invasion and drug resistance. Little is known, however, about how ERK3 expression level is upregulated in cancers. Here, we have identified the oncogenic polycomb group protein BMI1 as a positive regulator of ERK3 level in head and neck cancer cells...

BACKGROUND: Thyroid cancer is the fastest growing cancer in the United States. A small portion of differentiated thyroid cancers (DTCs; 2% to 13%) develop bone metastases, which can decrease a patient's survival rate by more than 60%. METHODS: A systematic literature search of studies, including patients with DTC with bone metastases, was conducted by following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A case series of patients with DTC diagnosed with bone metastases seen at our institution was also included...

CONCLUSION: Finnish head and neck cancer (HNC) patients show signs of severe malnutrition already at presentation, measured by bioelectric impedance analysis (BIA). BIA may be a practical method to detect malnutrition, analyze body composition, and to identify high-risk patients in this population. OBJECTIVES: BIA is a validated method for evaluating body composition and detecting malnutrition. Low phase angle (PA) is associated with increased mortality and morbidity...

BACKGROUND: Many survivors of head-and-neck cancer (HNC) suffer from late effects. Their overall quality of life deteriorates during treatment, followed by a slow recovery up to five years after treatment. We examined the association between the severity of physician-assessed late effects and the health-related quality of life (HRQoL) reported by survivors of HNC. MATERIAL AND METHODS: The analysis was based on data collected during follow-up for 136 survivors of cancer in the oral cavity, pharynx, larynx, or salivary glands...

Cone-beam CT (CBCT) is a widely used intra-operative imaging modality in image-guided radiotherapy and surgery. A short scan followed by a filtered-backprojection is typically used for CBCT reconstruction. While data on the mid-plane (plane of source-detector rotation) is complete, off-mid-planes undergo different information deficiency and the computed reconstructions are approximate. This causes different reconstruction artifacts at off-mid-planes depending on slice locations, and therefore impedes accurate registration between CT and CBCT...

BACKGROUND: Dysphagia is a significant side-effect following treatment for head and neck cancers, yet poor adherence to swallowing exercises is frequently reported in intervention studies. Behaviour change techniques (BCTs) can be used to improve adherence, but no review to date has described the techniques or indicated which may be more associated with improved swallowing outcomes. METHODS: A systematic review was conducted to identify behavioural strategies in swallowing interventions, and to explore any relationships between these strategies and intervention effects...
