BACKGROUND: FGFR1 is a receptor tyrosine kinases involved in tumor growth signaling, survival, and differentiation in many solid cancer types. There is growing evidence that FGFR1 amplification might predict therapy response to FGFR1 inhibitors in squamous cell lung cancers. To estimate the potential applicability of anti FGFR1 therapies in squamous cell carcinomas of the head and neck, we studied patterns of FGFR1 amplification using fluorescence in situ hybridization (FISH). MATERIALS AND METHODS: A tissue microarray was constructed from 453 primary treatment-naive squamous cell carcinomas of the head and neck regions with histopathological and clinical follow-up data [including oral cavity (n = 222), oropharynx (n = 126), and larynx (n = 105)]...

Introduction  Squamous cell carcinoma of the larynx is currently the second most common malignancy of the airway after lung cancer, and hypopharyngeal cancer accounts for fewer than 5% of head and neck cancers. The nonsurgical options for patients with this disease are related to significant long-term toxicities and the need for persistent tracheostomy, which adversely affects the quality of life of these patients. Objective  To evaluate the need for tracheostomy, and the influence of this in the overall and specific survival rates of patients diagnosed with all stages of laryngeal carcinoma treated by chemoradiotherapy...

Although juvenile-onset recurrent respiratory papillomatosis (JoRRP) generally involves a benign tumor on the larynx and other respiratory tract areas, almost all patients with this disease require repeated surgical intervention (to prevent airway obstruction during the course of illness) and various adjuvant therapies such as interferon, cidofovir, acyclovir, ribavirin, indole-3-carbinol, HspE7, mumps vaccine, photodynamic therapy, propranolol, cimetidine, and bevacizumab. Some case reports recently described the effectiveness of the quadrivalent human papillomavirus vaccine (HPV4) as an adjuvant therapy...

BACKGROUND & PURPOSE: Intensity-modulated proton therapy (IMPT) of superficial lesions requires pre-absorbing range shifter (RS) to deliver the more shallow spots. RS air gap minimization is important to avoid spot size degradation, but remains challenging in complex geometries such as in head-and-neck cancer (HNC). In this study, clinical endpoints were investigated for patient-specific bolus and for conventional RS solutions, making use of a Monte Carlo (MC) dose engine for IMPT optimization...

Laryngeal cleft is an anomaly of failed posterior closure of the larynx. Most cases are diagnosed and need treatment early in life due to respiratory and swallowing problems. We report an unusual case of a 66-year-old man with an asymptomatic laryngeal cleft until treatment for hypopharyngeal cancer. During concurrent chemoradiotherapy (CCRT), despite reduced tumor volume, he presented severe dysphagia and dyspnea, followed by severe pneumonia twice. Because CCRT had to be discontinued, a pharyngolaryngectomy was performed for the cancer treatment...

BACKGROUND: Tube feeding dependence is a commonly observed debilitating side-effect of curative (chemo-) radiation in head and neck cancer patients that severely affects quality of life. Prevention of this side-effect can be obtained using advanced radiation techniques, such as IMRT. For radiotherapy treatment plan optimization, it has become increasingly important to develop prediction models that enable clinicians to predict the risk of tube feeding dependence for individual patients...

INTRODUCTION: CD73 is an enzyme crucial in the metabolism of immunosuppressive adenosine. In cancer, it has various functions including tumor growth and metastases. Squamous cell carcinoma of the head and neck has an overall poor prognosis, also due to early spread of metastatic cells. MATERIALS AND METHODS: Tumor and lymph node specimens of 65 patients with HNSCC were subjected to immunohistochemical and H-score analysis of CD73 expression. Demographics, diagnoses, histopathology and subsequent outcome were analyzed...
