In the last decade, the incidence rate of detection rate of superficial head, neck and esophageal squamous cell carcinomas has increased with the development of endoscopic imaging techniques. These cancers are thought to arise independently subsequent to tissue exposure to a common carcinogen e.g. alcohol or tobacco. This phenomenon has been termed field cancerization. To determine the molecular background of the development of hypopharyngeal squamous cell carcinomas (HPSCCs) and double esophageal squamous cell carcinomas (DESCCs), the present study immunohistochemically assessed tumor-related protein expression [p53, Fhit (fragile histidine triad), E-cadherin and activation-induced cytidine deaminase (AID)], and subsequently determined the correlation between protein expression and clinicopathological data...

BACKGROUND: Head and neck cancer is increasingly being managed through nonsurgical approaches. Evidence comes from studies that have mainly examined patients with laryngeal cancer. Few studies, with limited sample size, have focused on the comparative outcomes of surgical and nonsurgical approaches in patients with advanced oropharyngeal or hypopharyngeal cancer. METHODS: Using a national cancer database, we identified 1603 and 1512 patients with clinical stage III/IVA oropharyngeal and hypopharyngeal cancer, respectively, treated between 2004 and 2009...

OBJECTIVES: Surgical oncology patients have multiple comorbidities and are at high risk of readmission. Prior studies are limited in their ability to capture readmissions outside of the index hospital that performed the surgery. Our goal is to evaluate risk factors for readmission for head and neck cancer patients on a national scale. MATERIAL AND METHODS: A retrospective cohort study of head and neck cancer patients in the Nationwide Readmissions Database (2013)...

OBJECTIVE: Today intensity modulated radiation therapy (IMRT) can be considered the standard of care in patients with head and neck tumors. IMRT treatment plans are proven to reduce acute treatment related side effects by optimal sparing of organs at risk (OAR). At the same time, areas that were out of the former 3D fields now receive low radiation doses. Amongst those areas the brainstem (BS) and the vestibular system (VS) are known to be physiologically connected to nausea and vomiting (NV)...

Laryngeal cancer metastases are relatively rare and mainly affect the lung. The medullary localization remains exceptional. We report the case of a patient followed for operated laryngeal cancer and whose oncologic control revealed a medullary localization. A patient followed for squamous cell carcinoma of the larynx, treated in 2010 by a partial surgery whose endoscopic control at 5 years revealed the presence of right arytenoid edema without suspicious lesions, multiple biopsies were made and which returned negative...

Head and neck cancers have a very poor prognosis and are common in France. They are subject to various recommendations for early detection and management, but there is no detailed data in the French general population to fuel the public health debate on it.A high-resolution population-based study about cancer management was conducted, using cancers registries in the north-west of France, on 1729 tumors diagnosed between 2008 and 2010.The tumors were diagnosed late (70.3% stage III-IV), mainly after the onset of symptoms (93...

BACKGROUND: Transoral videolaryngoscopic surgery (TOVS) was developed as a new distinct surgical procedure for hypopharyngeal cancer (HPC) and supraglottic cancer (SGC) staged at up to T3. However, long-term treatment outcomes of TOVS remain to be validated. METHODS: Under a straight broad intraluminal view provided by combined use of a distending laryngoscope and a videolaryngoscope, we performed en bloc tumor resection via direct bimanual handling of the ready-made straight-form surgical instruments and devices...

BACKGROUND: The aim of this study was to compare the therapeutic outcomes of total pharyngolaryngectomy with those of concomitant chemoradiotherapy in advanced hypopharyngeal cancer. METHODS: This is a retrospective multi-institutional study. The medical records of 979 patients with hypopharyngeal cancer, who were initially treated between 2006 and 2008, were reviewed. In this study, we matched a group of total pharyngolaryngectomy patients with a second group of chemoradiotherapy patients, according to age, gender, subsite, arytenoid fixation, cartilage invasion, and N classification, and analyzed overall survival, disease-specific survival, and locoregional control rates...

OBJECTIVES: The Ni classification of vascular change from 2011 is well documented for evaluating pharyngeal and laryngeal lesions, primarily focusing on cancer. In the planning of surgery it may be more relevant to differentiate neoplasia from non-neoplasia. We aimed to evaluate the ability of the Ni classification to predict laryngeal or hypopharyngeal neoplasia and to investigate if a changed cutoff value would support the recent European Laryngological Society (ELS) proposal of perpendicular vascular changes as indicative of neoplasia...

Background: Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma with distinct pathologic characteristics. The histogenesis of BSCC is not fully understood, and the cancer has been suggested to originate from a totipotent primitive cell in the basal cell layer of the surface epithelium or in the proximal duct of secretory glands. Materials and Methods: Twenty-six cases of head and neck BSCC from Asan Medical Center, Seoul, Korea, reported during a 14-year-period were subclassified into basal, ductal, and mixed subtypes according to the expression of basal (cytokeratin [CK] 5/6, p63) or ductal markers (CK7, CK8/18)...

Argonaute 2 (AGO2) protein is usually overexpressed in various head and neck squamous cell carcinoma. However, the precise molecular mechanisms of AGO2 in hypopharyngeal cancer have not yet been clearly understood. Here we found the AGO2 expression in hypopharyngeal cancer tissues were generally higher comparing with that of the corresponding adjacent noncancerous epithelium tissues, and these were associated with the more aggressive clinicopathologic features and the poor clinical outcomes. Stable knockdown of AGO2 protein retarded cell proliferation, migration, invasion, arrested cell cycle and induced apoptosis...

Gastric pull-up is a common procedure to reconstruct the continuity of the upper digestive tract after esophageal resection. However, this technique sometimes causes postoperative anastomotic leakage or stricture, resulting from insufficient blood flow at the distal end. To overcome this problem, additional microvascular venous anastomoses were performed. The purpose of this study was to compare the outcomes of post-surgical anastomotic leakage and stricture in patients with and without additional microvascular venous superdrainage after cervical esophageal and hypopharyngeal resection and gastric tube reconstruction...

Objective: To evaluate the values of enhanced CT and MRI for the diagnosis of thyroid cartilage invasion by laryngeal and hypopharyngeal cancer. Methods: One hundred and ninety-seven patients with primary laryngeal or hypopharyngeal cancer treated with surgery between January 2013 and December 2014 were included in this study. All patients underwent enhanced CT and MRI before surgery. With MRI using the techniques of fast recovery fast spin echo (FRFSE), spin echo echo planar imaging (SE-EPI) and diffusion weighted imaging (DWI), thyroid cartilage invasion was evaluated and the results of postoperative histopathological examination was used as a gold standard for the determination of thyroid cartilage invasion...

Circular RNAs (circRNAs), a novel class of endogenous noncoding RNAs, have been shown to have important roles in a number of diseases, including several types of cancers. We hypothesized that circRNAs are involved in the pathogenesis of hypopharyngeal squamous cell carcinoma (HSCC). To test our hypothesis, we initially compared the expression profiles of circRNAs in 4 paired HSCC and adjacent normal tissue samples by using a circRNA microarray. The microarray data showed that 2392 circRNAs, including 1304 upregulated and 1088 downregulated circRNA transcripts, were significantly dysregulated in the HSCC tissues...

The prognosis and survival of patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC) are related to the clinical staging. Tumor growth and metastasis are closely related to angiogenesis. Vascular endothelial growth factor (VEGF) and cyclooxygenase 2 (COX-2) are intimately related to the angiogenic process in which the blood supply required for neoplastic evolution is ensured. Considering the contributions of VEGF and COX-2 to the formation, growth, and progression of primary tumors, as well as their metastasis, it has been thought that the expression of these two factors might be related to the size and/or aggressiveness of laryngeal and hypopharyngeal cancer...
