The possible role of dietary fiber in the etiology of head and neck cancers (HNCs) is unclear. We used individual-level pooled data from 10 case-control studies (5959 cases and 12,248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium, to examine the association between fiber intake and cancer of the oral cavity/pharynx and larynx. Odds Ratios (ORs) and their 95% Confidence Intervals (CIs) were estimated using unconditional multiple logistic regression applied to quintile categories of non-alcohol energy-adjusted fiber intake and adjusted for tobacco and alcohol use and other known or putative confounders...

The high incidence rate of multiple carcinomas in the upper digestive tract is often explained in terms of involvement of the same underlying risk factors. It has been reported that the oral bacterium Streptococcus anginosus is associated with esophageal, gastric, and pharyngeal cancers. We previously reported occurrence of Porphyromonas gingivalis (P. gingivalis) DNA in esophagus cancer. In this study, the presence of P. gingivalis in specimens of various types of cancer from the upper digestive tract was investigated...

BACKGROUND AND STUDY AIMS:  Performing a percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients can be challenging because of the presence of trismus, pharyngeal obstruction by tumor, and pharyngoesophageal strictures or fistula. Pharyngocutaneous fistula (PCF) is a major postoperative concern in patients submitted to total laryngectomy (TL). In the medical literature to date, the cervical fistula has been used as an access to PEG in only four reports. The aim of this study was to evaluate the safety of cervical fistula for insertion of a PEG tube...

Background: In its standard form, the parametric survival model assumes that the shape parameter is constant and the scaling parameter is not. This article focuses on how a model with a non-constant shape parameter could make differences in oncology studies and lead to more precise results. Materials and Methods: Online data for part of a large clinical trial conducted by the Radiation Oncology Group in the United States available online on UMass Amherst`s website were employed. The full study included patients with squamous cell carcinoma from fifteen sites in the mouth and throat, although only data on three sites in the oropharynx reported by the six largest institutions were considered here...

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: Over the last decade, the causal link between human papillomavirus (HPV) infection and squamous cell carcinoma of the anus (SCCA) has been well described. Because HPV infection in one site is often associated with other sites of infection, it then follows that patients with SCCA may have an increased risk of additional HPV-related cancers. Identifying and targeting at-risk sites through cancer screening and surveillance may help to guide best practices. The current study sought to ascertain sites and risk of HPV-related second primary malignancies (SPMs) in survivors of SCCA...

Larynx is the second most common site for cancer in the upper aerodigestive tract. One of the dreaded complications following total laryngectomy has been pharyngo cutaneous fistula (PCF). PCF merits special attention due to its significant negative impact on the recovery process. Total laryngectomy profoundly alters speech. Effective voice restoration is essential for the rehabilitation of these patients. Inadequate consensus exists as to the best technique of pharyngeal repair to decrease incidence of PCF and ensure good quality voice following total laryngectomy...

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 and aims Chemoradiotherapy for head and neck cancer (HNC) with/without laryngectomy commonly causes dysphagia. Pharyngoesophageal junction (PEJ) stricturing is an important contributor. We aimed to validate a functional lumen imaging probe (the EndoFLIP system) as a tool for quantitating pretreatment PEJ distensibility and treatment-related changes in HNC survivors with dysphagia and to evaluate the diagnostic accuracy of EndoFLIP-derived distensibility in detecting PEJ strictures. Methods We studied 34 consecutive HNC survivors with long-term (> 12 months) dysphagia who underwent endoscopic dilation for suspected strictures...

Nasopharyngeal carcinoma (NPC) is a common cancer in Southeast Asia, for which radiotherapy and/or chemotherapy are the primary treatment methods. Many herbs are known to have potential uses in chemotherapy; however, the mechanisms underlying the observed antitumor activity of Ajuga bracteosa (AB) against NPC remain unclear. We explored the antitumor effects of AB, which was shown specifically to induce mitotic delay in pharyngeal (Detroit 562) and nasopharyngeal (Hone-1) cancer cells. Proliferation of cancer cells after exposure to aqueous extract of A...
