Introduction: Laryngocele is an air-filled dilatation of the laryngeal saccule that extends upward within the false vocal folds. Different etiologies lead to laryngocele congenital malformation, weakness of the laryngeal tissues and increased intralaryngeal pressure. Laryngocele may be a secondary iatrogenic complication following subtotal laryngectomy.   Case Report: We report the case of a 61...

Laryngeal cancer is a rare type of neoplasia, constituting approximately 2% of all human cancers. Mutations of the ras gene family is one of the main activating mechanisms in human cancer. Their involvement in head and neck cancer has been mainly demonstrated at the level of the overexpression whereas ras mutations in these cancers are rare in the Western world. In the present study we explored...

Purpose: to describe the number of cases of patients with laryngeal cancer in the Northeast and the possibilities of surgical and therapeutic interventions funded by the Public Service. Methods: a descriptive epidemiological study, which relied on secondary data obtained via query-based Datasus data, collected data for the period from January 2008 to December 2012 Results: increasing the number...

BACKGROUND This study aimed at the evaluation of the expression of metallothionein (MT) in laryngeal carcinoma and its correlation with the expression of Ki-67 antigen and p53 protein and selected clinical and pathological variables in view of their potential prognostic significance. MATERIALS AND METHODS Sixty-five laryngeal cancer patients were retrospectively analysed. Expression of MT, Ki...

Head and neck cancer is the sixth most common cancer worldwide and laryngeal cancer represents the largest subgroup. However, the molecular mechanism underlying its malignant behavior and progression is not clarified. Accumulating evidence has shown that Notch1 signaling pathway plays a central role in carcinogenesis, but its potential role in regulating the development of laryngeal carcinoma, ...

Cancer Therapy A two-edged-sword strategy for anticancer and chondroprotective treatment is approached by combining two key players, as reported Mi-Lan Kang, Hak-Joon Sung, co-workers in article number 2101558. Cell-membrane-derived nanoparticles (CMNPs) induce hypoxic cell–cell packing seen commonly cancer growth chondrogenesis. Notch-1 suppressor display on CMNPs inhibits angiogenesis efficie...

We aimed to measure the invasion ability of Hep-2 laryngeal cancer cells after treatment with C-erbB-2-small interfering RNA (siRNA)-chitosan nanoparticles, and assess the applied value of chitosan nanoparticle-mediated C-erbB-2 interference in inhibiting laryngeal cancer invasion and metastasis. Nanoparticles of approximately 100 nm, comprising C-erbB-2 siRNA packaged with chitosan, were prepa...

In a case-control study of all new cases of laryngeal cancer in Denmark from 1980 to 1982, 326 cases and 1134 community selected controls participated. Questionnaires were used to obtain information on education, occupation, and number of occupational exposures as well as smoking and drinking habits. High risk ratios for laryngeal cancer were found for semiskilled and unskilled workers, workers...

Importance. Laryngeal cancer infrequently results in distant metastases, but metastasis to skeletal muscle is extremely uncommon. Observations. A 55-year-old male presenting with progressive dyspnea and hoarseness was found to have Stage IVA T4aN2cM0 laryngeal cancer and eventually underwent total laryngectomy. Before the patient could be started on adjuvant chemoradiation, the patient develope...
