BACKGROUND: Data have been limited on donor-site mechanical bowel obstruction after pharyngolaryngectomy with free jejunum graft reconstruction. METHODS: Using a nationwide Japanese inpatient database, we extracted data on patients who underwent pharyngolaryngectomy for hypopharyngeal cancer between July 2007 and March 2014. A Cox proportional hazard model was used to determine the association between background characteristics and the occurrence of mechanical bowel obstruction...

PURPOSE: Bile-containing gastroesophageal reflux may promote cancer at extraesophageal sites. Acidic bile can accelerate NF-κB activation and molecular events, linked to premalignant changes in murine hypopharyngeal mucosa (HM). We hypothesize that short-term in vivo topical application of NF-κB inhibitor BAY 11-7082 can prevent acidic bile-induced early preneoplastic molecular events, suggesting its potential role in disease prevention. EXPERIMENTAL DESIGN: We topically exposed HM (C57Bl/6j wild-type) to a mixture of bile acids at pH 3...

We previously demonstrated that acidic bile activates NF-κB, deregulating the expression of oncogenic miRNA markers, in pre-malignant murine laryngopharyngeal mucosa. Here, we hypothesize that the in vitro exposure of human hypopharyngeal cells to acidic bile deregulates cancer-related miRNA markers that can be reversed by BAY 11-7082, a pharmacologic NF-κB inhibitor. We repetitively exposed normal human hypopharyngeal primary cells and human hypopharyngeal keratinocytes to bile fluid (400 μmol/L), at pH 4...

Bile-containing gastro-duodenal reflux has been clinically considered an independent risk factor in hypopharyngeal carcinogenesis. We recently showed that the chronic effect of acidic bile, at pH 4.0, selectively induces NF- κ B activation and accelerates the transcriptional levels of genes, linked to head and neck cancer, in normal hypopharyngeal epithelial cells. Here, we hypothesize that NF- κ B inhibition is capable of preventing the acidic bile-induced and cancer-related mRNA phenotype, in treated normal human hypopharyngeal cells...

BACKGROUND: The purpose of the study was to determine trends in age-adjusted incidence rates (AAIR) and survival probability in head and neck cancers (HNCs) in the Danish population from 1980 to 2014. MATERIAL AND METHODS: All patients registered with HNC in the nationwide Danish Cancer Registry from 1980 to 2014 were included. We evaluated the AAIR per 100,000 and the average annual percent change (AAPC). The relative survival probability at 5 years was calculated in relation to gender, anatomical location and histology, and we constructed age-period-cohort models of incidence...

The current study aimed to investigate the incidence and survival patterns of HNSCCs arising from different anatomic sites, potentially related (the oropharynx) or unrelated (the oral cavity, the larynx/hypopharynx) to HPV, to provide clues on possible growing impact of HPV in the epidemiology of HNSCC in Italy. Epidemiological data were retrieved from ten long-term Cancer Registries covering a population of 7.8 million inhabitants. Trends were described by means of the estimated annual percent change (APC) stratified by age and gender, and compared between HPV-related and HPV-unrelated anatomical sites...

Endoscopic transoral surgery for hypopharyngeal cancer is an effective treatment option to avoid invasive open surgery or chemoradiation. Here we describe the case of a 66-year-old patient with cT2N0M0 pyriform sinus cancer whom we treated using a transoral-transhyoid endoscopic approach. Using this approach, a transhyoid route was created in addition to the transoral route and used to extirpate the tumor. En bloc resection of the tumor was completed without difficulty. A combined transoral-transhyoid approach is a useful surgical option for treatment of selected patients with hypopharyngeal cancer...

The present study aimed to identify significant correlations between gene expression and chemotherapy response to 5-fluorouracil (5-FU)/cisplatin in head and neck squamous cell carcinoma (HNSCC), and to identify patients who would benefit from induction chemotherapy for both organ preservation and survival. A total of 64 patients who underwent radical treatment for HNSCC were enrolled. All patients received induction chemotherapy with 5-FU/cisplatin and tumor responses were evaluated. Pretreatment biopsy specimens from all patients were assayed for mRNA expression of thymidylate synthase, dihydropyrimidine dehydrogenase (DPD), orotate phosphoribosyltransferase, tymidine phosphorylase, glutathione S-transferase-pi, p53, RB Transcriptional Corepressor 1, B-cell lymphoma 2 (Bcl-2), Bcl-xL, E2F Transcription Factor 1, epidermal growth factor receptor, human epidermal growth factor receptor 2, phosphoinositide 3-kinase, phosphatase and tensin homolog, vascular endothelial growth factor (VEGF), cyclooxygenase-2, XPA, DNA Damage Recognition And Repair Factor, excision repair cross-complementing 1 (ERCC1), multidrug resistance gene 1 (MDR1), multidrug resistance-associated protein 1, equilibrative nucleoside transporter 1 and β-tubulin by reverse transcription-quantitative polymerase chain reaction, and the association between the expression levels of these genes and patient response to chemotherapy was determined...

OBJECTIVE: In the treatment of head-neck cancer, parotid-sparing intensity-modulated radiotherapy (IMRT) could reduce the incidence of xerostomia. When the parotid glands cannot be sufficiently spared because of the widespread tumor, contralateral superficial lobe parotid-sparing (CSLPS)-IMRT could be used to reduce marginal recurrence, however the success of this approach remains to be determined. The primary purpose of this study was to compare the incidence of xerostomia between three-dimensional conformal radiotherapy (3D-CRT) and CSLPS-IMRT for oropharyngeal and hypopharyngeal cancer...

BACKGROUND: Restoring the anatomy and function of a partial laryngopharyngectomy with hemicricoid defect is an extremely challenging area in head and neck cancer surgery. Procedures such as tracheal autotransplantation described for these defects are complex and attempted in very few centers. Therefore, the purpose of this article was to share our technique of reconstructing such defects with tracheal advancement with myomucosal island flap for laryngopharyngeal defect (TAMMIL), which allows functional reconstruction of the larynx...

BACKGROUND: Nivolumab, an anti-programmed cell death-1 (PD-1) monoclonal antibody used as an immune checkpoint inhibitor, is commonly employed for its anti-tumor effects against various types of malignant tumors. However, its administration is complicated by immune-related adverse events (irAEs), including pneumonitis. CASE PRESENTATION: We present a case series of four patients with malignant melanoma, non-small cell lung cancer, and hypopharyngeal carcinoma who demonstrated pneumonitis induced by nivolumab, and further review clinicopathological characteristics of these patients in comparison with those of previously reported patients with nivolumab-induced pneumonitis...

BACKGROUND/AIM: Head and neck squamous cell carcinomas (HNSCC) are characterized by aggressiveness, early recurrence and lymph node metastasis. Therefore, there is an urgent need to identify new biomarkers and drug targets. MATERIALS AND METHODS: Neck dissection specimens from 11 patients diagnosed with hypopharyngeal cancer were analyzed for their lymphatic vessel density (LVD) by lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) immunostaining, expression of eukaryotic initiation factor 4E (eIF4E) and levels of secreted protein acidic and rich in cysteine (SPARC) using immunoblot analysis...

Various studies have investigated laryngeal function and survival after induction chemotherapy in hypopharyngeal carcinoma, but potential factors to help predict response rates after induction chemotherapy remain unknown. This retro- spective study evaluated which factors are related to an ineffective response to two-cycle docetaxel, cisplatin, and 5-fluoro- uracil (TPF) induction chemotherapy in hypopharyngeal carcinoma to determine potential candidates for this treatment in clinical practice. From Jan 2005 to Dec 2015, 81 patients diagnosed with hypopharyngeal squamous cell carcinoma based on a pathological examination were analyzed...

Minor Salivary Gland tumours are rare, representing 2% of the head and neck tumours and less than 1% of hypopharyngeal cancers. The most common subtype of minor salivary gland tumours is adenoid cystic carcinoma. Although there are several case reports discussed it, there are only two reports discussing hypopharyngeal presentation in the literature, and they were treated by surgical resection. Despite that, our case report still to be unique as it presents a case of irresectable locally advanced tumour subjected to a trial of induction therapy...

Clarifying the epigenetic regulation of tumor-related genes (TRGs) can provide insights into the mechanisms of tumorigenesis and the risk for disease recurrence in HPV-negative head and neck cancers, originating in the hypopharynx, larynx, and oral cavity. We analyzed the methylation status of the promoters of 30 TRGs in 178 HPV-negative head and neck cancer patients using a quantitative methylation-specific PCR. Promoter methylation was correlated with various clinical characteristics and patient survival...
