BACKGROUND: Treatments for head and neck squamous cell carcinoma (HNSCC) are associated with toxicities that lead to emergency department presentation. METHODS: We utilized data from an ongoing prospective cohort of newly diagnosed, previously untreated patients (N = 298) with HNSCC to evaluate the association between clinical and epidemiologic factors and risk for and frequency of emergency department presentation. Time to event was calculated from the date of treatment initiation to emergency department presentation, date of death, or current date...

BACKGROUND: Energy-based surgical devices, including electrotome, the Harmonic scalpel, and LigaSure, have been widely applied in thyroid surgery, although a comparison of their safety and efficacy has not been reported yet. In this study, we investigated the feasibility of using hemostatic energy-based surgical devices during thyroid surgery in a canine model. METHODS: Twenty-four beagle dogs were randomly divided into the following groups: electrotome (30 kW), electrotome (15 kW), the Harmonic scalpel (output level 3), and LigaSure (middle gear)...

BACKGROUND: The β-nitrostyrene family possesses anticancer properties. In this study, β-nitrostyrene derivative CYT-Rx20 (3'-hydroxy-4'-methoxy-β-methyl-β-nitrostyrene) was synthesized and investigated its anticancer activity in oral cancer. METHODS: Anticancer activity of CYT-Rx20 and the underlying mechanisms were analyzed using cell viability assay, reactive oxygen species (ROS) generation assay, fluorescence-activated cell sorter analysis, annexin V staining, comet assay, glutathione (GSH)/glutathione disulfide (GSSG) ratio, immunoblotting, soft agar assay, nude mice xenograft study, and immunohistochemistry...

Breast cancer is the most common cancer in women and is the second most common cause of cancer-related death. Despite the relatively high prevalence of this disease, breast cancer manifestations in the head and neck are relatively rare. Supraclavicular lymphadenopathy and bony metastases to the mandible and maxilla are the most common manifestation of breast cancer in the head and neck. Head and neck metastases are the first presentation of distant disease in approximately one-third of cases. The prognosis of breast cancer with distant metastases to the head and neck is generally poor, and the management of these lesions is controversial...

PURPOSE: Preoperative lymphoscintigraphy is the standard for the identification of sentinel lymph nodes (SLNs) in melanoma. The impact of negative scintigraphy [nonvisualization (NV) of the SLN] on surgical outcomes is inadequately reported in the literature. The objectives of this study were to determine the incidence, predictive factors, and surgical outcomes of NV in clinically node-negative melanoma patients. PATIENTS AND METHODS: A retrospective review of a prospective, Institutional Review Board approved, melanoma sentinel node database from January 2005 to August 2015 was performed...

Cellular processes like differentiation, mitotic cycle, and cell growth are regulated by tyrosine kinases with known oncogenic potential and tyrosine phosphatases that downmodulate the first. Therefore, tyrosine phosphatases are recurrent targets of gene alterations in human carcinomas. We and others suggested recently a tumor suppressor function of the PTPRD tyrosine phosphatase and reported homozygous deletions of the PTPRD locus in laryngeal squamous cell carcinoma. In this study, we investigated other gene-inactivating mechanisms potentially targeting PTPRD, including loss-of-function mutations and also epigenetic alterations like promoter DNA hypermethylation...

Objective: Squamous cell carcinoma (SCC) is a life threatening lesion but there has been only limited research about its frequency in Iran. The aim of this study was to evaluate the frequency of squamous cell carcinoma of the head and neck in the records of the pathology department of Imam Khomeini hospital in Ahvaz between 2005 and 2015. Methods: The retrospective and cross-sectional study was conducted using 55,708 medical records of cancer throughout the body, accumulated in the pathology department of Imam Khomeini in Ahvaz in the designated period...

BACKGROUND: The anterior lateral thigh flap (ALT) has become increasingly important in reconstructive surgery in the head and neck region. To cope with the problem of anatomical variability in the supplying blood vessels, preoperative evaluation is desirable. Purpose of the study is to compare the most commonly used Doppler devices Handheld Doppler (HD) and Color Doppler Ultrasonography (CDU) for their clinical reliability. METHODS: Forty five consecutive head and neck cancer patients (mean age 66...

The literature regarding orbital decompression for thyroid eye disease is vast, spanning multiple specialty areas including neurosurgery, head and neck, maxillofacial and ophthalmic plastic surgery. Although techniques have advanced considerably over the more than 100 years during which this procedure has been performed, the four major approaches remain: transorbital, transcranial, transantral and transnasal. The explosion in literature related to orbital decompression has mostly involved minor technical variations on broader surgical themes...

Head and neck cancers constitute a multifactorial global disease burden and are associated with human papilloma virus (HPV) as a possible risk factor. The aim of the study is to understand the relationship between HPV and the development of head and neck lesions in Indian patients. To this end, frequency of HPV was assessed in relation to different demographic and etiological features and correlated with patient survival. The prevalence of HPV significantly increased from mild dysplastic lesions (43.6%) to head and neck squamous cell carcinoma (HNSCC) stage IV (68...

INTRODUCTION: Malignant cutaneous adnexal neoplasms are rare and have been characterized only recently. They can occur at any age but preferentially in elderly. There are 3 of them: trichoblastic carcinoma, trichilemmal carcinoma and malignant pilomatricoma. The aim of our study was to make a diagnostic and therapeutic update about these tumors when located at the face or at the scalp. MATERIALS AND METHODS: A bibliographic research was made on PubMed using following keywords: appendage skin carcinoma AND pathology AND/OR therapeutic...

PURPOSE: To investigate the patterns of regional recurrences with emphasis on recurrences in the electively irradiated lymph node regions after dose de-escalation to 40Gy (EQD2Gy) in head and neck cancer. METHODS AND MATERIALS: Two hundred thirty-three patients treated with radio(chemo)therapy using 40Gy (EQD2Gy) to the elective lymph node regions were included. All regional recurrences were reconstructed and projected on the initial radiotherapy planning Computed Tomography studies to identify the localization of recurrence...

OBJECTIVES: Head and neck squamous cell carcinoma (HNSCC) caused by the human papilloma virus (HPV) has an improved prognosis relative to HPV-negative tumors. Patients with HPV-positive disease may benefit from different treatment modalities in order to optimize survival and quality of life. We sought to investigate HPV-positive HNSCC within the military veteran population, and analyze the role of treatment modality in outcomes of patients with HPV-positive and HPV-negative tumors. METHODS: Patients diagnosed with HNSCC between January 1, 2010 and December 31, 2014 at one regional veterans health center were retrospectively examined...

INTRODUCTION: To manage the complications of irradiation of head and neck tissue is a challenging issue for the otolaryngologist. Definitive treatment of these complications is still controversial. Recently, hyperbaric oxygen therapy is promising option for these complications.

We studied cancer patients for possible PAH exposure, using urinary concentration of 1-hydroxypyrene (1-OHP) as a biomarker of internal dose of polycyclic aromatic hydrocarbons (PAHs). The subjects included in this study belonged to various socio-demographic backgrounds, and were diagnosed with cancer (i.e. lung, head and neck or digestive tract cancer). In general, we observed high concentration of urinary 1-OHP among digestive tract cancer patients, compared with the controls (CN) (mean 1.06, median 1.03 and mean 0...
