Laryngeal cancer is one of the largest subgroups of head and neck cancers. In addition to smoking and alcohol consumption, genetic polymorphisms are also risk factors for the development of laryngeal cancer. However, the exact relation between genetic variants and pathogenesis of laryngeal cancer has remained elusive. The aim of this study was to examine UGT1A1*6 (rs4148323 A/G) polymorphisms i...
MicroRNAs (miRs, miRs) is a class of small non-coding RNAs, which posttranscriptionally regulate gene expression. Deregulated miRs are frequently obseved in patients with laryngeal cancer. In addition, numerous studies have showed miRs play significant roles in the pathogenesis of laryngeal cancer through regulating tumor cell proliferation, metastasis, invasion and apoptosis. miR can play eith...
BACKGROUND MicroRNA-23a (miR-23a) has been demonstrated to play an important role in the development of several types of cancer, but its role in tumorigenesis of laryngeal carcinoma is still unclear. The aim of this study was to investigate the expression patterns and clinical implications of miR-23a in laryngeal cancer. METHODS Quantitative RT-PCR was performed to evaluate the expression lev...
BACKGROUND MicroRNA (miRNA) is an emerging subclass of small non-coding RNAs that regulates gene expression and has a pivotal role for many physiological processes including cancer development. Recent reports revealed the role of miRNAs as ideal biomarkers and therapeutic targets due to their tissue- or disease-specific nature. Head and neck cancer (HNC) is a major cause of cancer-related morta...
Gastroesophageal reflux disease (GERD), or its variation known as laryngopharyngeal reflux (LPR), has been recognized as a potential cause of several laryngeal disorders. Patients with laryngeal cancer have lifestyle risk factors, especially tobacco and alcohol consumption, that play an etiological role in the development of their cancer but also places them at risk for reflux. The question the...
We firstly conducted a case-control study to investigate the role of two SNPs in MLL3 gene (rs6943984 and rs4725443) in the development of laryngeal cancer in a Chinese population. Between May 2012 and October 2014, a total of 171 patients with laryngeal cancer and 251 control subjects were collected from the Zhumadian Central Hospital. Genotyping of MLL3 rs6943984 and rs4725443 were analyzed u...
background laryngeal cancer though accounts for only 1.5% of all malignant neoplasm. scientific evidence has shown that cancers of the oral cavity, larynx, lung and esophagus are associated with cigar smoking. the present study is to examine by case-control method the impact of smoking on laryngeal cancer. material and methods one hundred and six hospitalized cases of otolaryngology department ...
This study investigated the factors affecting the surgical treatment effect on patients with laryngeal cancer. The clinical data (including the sex, age, smoking index, drinking, primary tumor site, tumor (T) stage, lymph nodes (N) stage, tumor differentiation degree, tumor diameter, surgical method, lymph node metastasis and cervical lymph node dissection) of 215 patients with laryngeal cancer...
BACKGROUND Preclinical animal models to study laryngeal cancer are nonexistent. The purpose of this study was to describe a novel mice laryngeal cancer model. METHODS A total of 18 six-week-old A/J mice were used. Animals underwent microdirect laryngoscopy, superficial larynx scratching, and instillation of N-methyl-N-nitrosourea (MNU) at 2 different concentrations (15 μL and 30 μL) or dimeth...
AIM This study aims to investigate the possible role of H. pylori as a cause of laryngeal squamous cell carcinoma. METHOD This controlled study was performed with 31 consecutive laryngeal cancer and 28 cancer-free patients who underwent direct laryngoscopy and biopsy of laryngeal lesions. To document the previous H. pylori infection, serological analysis of the antibody titers was done. Immun...
