BACKGROUND: Surgical treatment of cancers that arise from or invade the hypopharynx presents major reconstructive challenges. Reconstructive failure exposes the airway and neck vessels to digestive contents. METHODS: We performed a national N = near-all analysis of the administrative dataset to identify pharyngolaryngectomies in England between 2002 and 2012. Information about morbidity, pharyngeal closure method and post-operative complications was derived. RESULTS: There were 1589 predominantly male (78%) patients whose mean age at surgery was 62 years...

A 72-year-old male with nausea and heartburn was found to have early pharyngeal squamous cell carcinoma, superficial and advanced esophageal squamous cell carcinoma and early esophageal adenocarcinoma by esophagogastroduodenoscopy. Computerized tomography demonstrated left cardiac lymph node swellings. We prioritized the treatment for esophageal squamous cell carcinoma, as this was the most advanced cancer among the triple primaries. The patient underwent neoadjuvant chemotherapy for esophageal squamous cell carcinoma followed by esophagectomy...

Even with advanced inverse-planning techniques, radiation treatment plan optimization remains a very time-consuming task with great output variability, which prompted the development of more automated approaches. One commercially available technique mimics the actions of experienced human operators to progressively guide the traditional optimization process with automatically created regions of interest and associated dose-volume objectives. We report on the initial evaluation of this algorithm on 10 challenging cases of locoreginally advanced head and neck cancer...

We reviewed available evidence on coffee drinking and the risk of all cancers and selected cancers updated to May 2016. Coffee consumption is not associated with overall cancer risk. A meta-analysis reported a pooled relative risk (RR) for an increment of 1 cup of coffee/day of 1.00 [95% confidence interval (CI): 0.99-1.01] for all cancers. Coffee drinking is associated with a reduced risk of liver cancer. A meta-analysis of cohort studies found an RR for an increment of consumption of 1 cup/day of 0.85 (95% CI: 0...

Heparan sulfate (HS) mediates the activity of various growth factors including TGF-β. Heparanase is an endo-glucuronidase that specifically cleaves and modifies HS structure. In this study, we examined the effect of heparanase expression on TGF-β1-dependent signaling activities. We found that overexpression of heparanase in human tumor cells (i.e., Fadu pharyngeal carcinoma, MCF7 breast carcinoma) attenuated TGF-β1-stimulated Smad phosphorylation and led to a slower cell proliferation. TGF-β1-stimulated Akt and Erk phosphorylation was also affected in the heparanase overexpression cells...

BACKGROUND: Induction chemotherapy (ICT) in patients with head and neck cancer has been studied since a long time. The addition of taxanes to the cisplatin and 5-fluorouracil (5FU) (PF) regimen results in superior antitumor activity. We did this study to see the response and toxicity of ICT with cisplatin and ifosfamide followed by concurrent chemoradiotherapy (CRT) in locally advanced, unresectable squamous cell carcinoma of head and neck (SCCHN). AIMS: The aim of this study was to see the results of ICT using cisplatin and ifosfamide regimen in locally advanced unresectable SCCHN in terms of acute and chronic toxicity and response to treatment...

Dysphagia after primary chemoradiotherapy or radiation alone in pharyngeal cancers can have a devastating impact on a patient's physical, social and emotional state. Establishing and validating efficient dysphagia-optimised radiotherapy techniques is, therefore, of paramount importance in an era where health-related quality of life measures are increasingly influential determinants of curative management strategies, particularly as the incidence of good prognosis, human papillomavirus-driven pharyngeal cancer in younger patients continues to rise...

Recent investigations by our study team have demonstrated patients using gabapentin for pain management during chemoradiotherapy (CRT) do well maintaining swallowing during treatment with less need for narcotic pain medication, PEG dependence, weight loss, and short-term swallowing morbidity. The purpose of this investigation was to characterize the long-term swallowing function of these patients 1-year following treatment. Sequential patients receiving CRT for oropharyngeal cancer and concurrent gabapentin were evaluated 1-year following treatment for swallowing outcomes...

BACKGROUND: Chin-up posture is frequently used to manage oral dysphagia after head and neck cancer. This prospective study investigates the effects of chin-ups on the sequence of pharyngeal swallowing events. METHODS: Twelve healthy young adults performed 45 consecutive swallows of 5 mL water across 3 phases on videofluoroscopy: 5 swallows in the neutral head position; 30 swallows during chin-up posture; and 10 swallows in the neutral head position. Swallowing kinematic and bolus flow measures for 9 swallowing events were recorded...

A major cause of morbidity and mortality in patients with cancer is infection. Since the introduction of the Haemophilus influenzae type b (Hib) vaccine in the United States in the 1990s, invasive H influenzae infection has become less common. We report on 5 patients with cancer and invasive H influenzae infection. A literature review was also performed of the dominant Haemophilus subtype and the clinical features associated with the infection and concomitant cancer. Of the 17 cases found in the literature, had hematological malignancies and 1 case each had thymoma, schwannoma, teratoma, and pancreatic, Merkel cell, pharyngeal, laryngeal, and rectal carcinomas...

Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our hospital. Conventional endoscopy showed that the tumor had invaded the hypopharynx. When inspecting the hypopharynx and the orifice of the esophagus, we asked the patient to blow hard and puff her cheeks with her mouth closed (trumpet maneuver)...

The superior laryngeal artery is the principal artery supplying the laryngeal mucosa, musculature, and glands. Knowledge of variations in the origin of superior laryngeal artery could prove to be very useful during reconstructive surgeries of the larynx, partial laryngectomy, laryngeal transplantation, and also during procedures like super-selective intra-arterial chemotherapy for laryngeal and hypolaryngeal cancers. However, relatively few studies have been done on the superior laryngeal artery in comparison to its clinical importance...

Common cutaneous human papillomavirus (HPV) types induce skin warts, whereas species beta HPV are implicated, together with UV-radiation, in the development of non-melanoma skin cancer (NMSC) in immunosuppressed patients. Licensed HPV vaccines contain virus-like particles (VLP) self-assembled from L1 major capsid proteins that provide type-restricted protection against mucosal HPV infections causing cervical and other ano-genital and oro-pharyngeal carcinomas and warts (condylomas), but do not target heterologous HPV...

PURPOSE: To develop a swallowing prediction system (SPS) using force sensing sensors and evaluate its feasibility. METHODS: The SPS developed consists of force sensing sensor units, a thermoplastic mask, a signal transport device and a control PC installed with an in-house software. The SPS is designed to predict the pharyngeal stage of swallowing because it is known that internal organ movement occurs in pharyngeal stage. To detect prediction signal in the SPS, the force sensing sensor units were attached on both the submental muscle region and thyroid cartilage region of the thermoplastic mask...
