Head and neck squamous cell carcinoma (HNSCC) is one of the most frequent cancers worldwide and is associated with poor survival and significant treatment morbidity. The immune profile in patients with HNSCC is immunosuppressive and presents cytokine-mediated adaptive immune responses, triggered apoptosis of T cells, and alterations in antigen processing machinery. Bacille Calmette-Guerin (BCG) immunotherapy has been used successfully as a treatment for several types of cancer. In the present study, we sought to determine the antitumor effect of soluble mediators from peripheral blood mononuclear immune cells (PBMCs) activated with BCG vaccine in a three-dimensional coculture model of HNSCC growth using FaDu hypopharynx carcinoma squamous cells...

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...

The aim of this presentation was to share an uncommon form of sudden death, suffered by a 64-year-old woman, due to a mechanical obstruction of hypopharynx by an undiagnosed B-cell lymphoma, infiltrating the inferior pharyngeal constrictor muscle. A forensic approach by means of scene investigation, circumstantial data collection, autopsy, and histological and toxicological investigations led to conclude that the cause of death was asphyxia, correlated with B-cell lymphoma of the hypopharynx. The autopsy examination highlighted the presence of a wall thickening, infiltrating, and projecting into the hypopharynx lumen...

This case report describes the use a new flexible robotic system in otolaryngology, the FlexRobot(®) for cricopharyngeal myotomy in cadaver dissections, and for the treatment of a patient with esophageal stenosis and secondary dysphagia and dysphonia. The Flexrobot(®) facilitates access to the hypopharynx with increased proximity to the surgical field and improved optics, allowing more exact dilatation and injection in our patient. It also would allow surgeons to reach deep inside the cavity of the hypopharynx into anatomical regions that are typically inaccessible without an open approach, as shown in our cadaveric procedure, where full exposure of the posterior aspect of the cricopharyngeus and isolation of the muscle belly were achieved...

INTRODUCTION: Radical laryngeal surgeries for extensive laryngeal and hypopharyngeal tumors often require a permanent tracheostomy, which has an immense impact on the quality of life of patients. A minimally invasive technique such as transoral laser microresection (TLM) followed by radiotherapy can preserve the functions of the voice and swallowing. The aim of this study is to evaluate the role of laser debulking in the treatment of carcinoma of the larynx and hypopharynx, to evaluate the response of the tumor to subsequent radiotherapy, and also to assess the usefulness of laser in avoiding tracheostomy and functional preservation of the voice and swallowing...

M Abu-Serriah, S Loughran
Circumferential defects of the hypopharynx are a reconstructive challenge. Various local, regional and free flaps have been described with each having advantages and disadvantages in terms of functional outcomes. The fasciocutaneous radial forearm free flap (RFFF) is one of the most common free flaps used for reconstructing circumferential hypopharyngeal defects. The skin paddle is pliable and reasonably matches the native hypopharyngeal wall. It is easy to raise, has predictable vascular anatomy and a long pedicle...

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...

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...

Giant fibrovascular polyps of the esophagus are rare benign tumors arising from the cervical esophagus or hypopharynx. Radiologic and endoscopic investigation may struggle to identify a stalk or to delineate the tumor as luminal or submucosal in origin. Excision is advised, although the diagnosis, and therefore the optimal operative approach, may not be apparent until the time of operation. Individual case reports describe the technical success of surgical excision but rarely include follow-up. Our case series highlights the range of approaches for surgical excision and also the importance of long-term follow-up because of the risk of recurrence and potential for airway obstruction...
