The association of education, tobacco smoking, alcohol consumption, and interleukin-2 (IL-2 +114 and -384) and -6 (IL-6 -174) DNA polymorphisms with head and neck squamous cell carcinoma (HNSCC) was investigated in a cohort study of 445 subjects. IL-2 and IL-6 genotypes were determined by real-time PCR. Cox regression was used to estimate hazard ratios (HR) and 95% confidence intervals (95%CI) ...
Larynx cancer is the second most common type of cancer among all head and neck cancers. Deregulation of epigenetic effectors, including altered expression of histone methyltransferases from the MLL (mixed lineage leukemia) family, have been reported in many cancer types, yet little is known concerning their involvement in larynx cancer. Our objective was to determine the expression profile of M...
Despite advances in diagnosis and treatment, the prognosis for patients with stage III-IV laryngeal cancer is not significantly different than it was four decades ago [1]. This failure to improve survival is multifactorial and is likely linked to controversy surrounding optimal treatment regimens for a heterogeneous patient and tumor population. At the root of this controversy is a lack of rand...
We systematically analyzed the association of nine SNPs of seven key NER pathway genes with the development of laryngeal cancer patients, and investigated whether NER pathway polymorphisms could serve as potential biomarkers for laryngeal cancer risk. 271 patients with pathologically proven laryngeal cancer and 271 control subjects were included in our study. Genotyping of ERCC1 rs11615 and rs2...
BACKGROUND Tobacco smoking and alcohol drinking generate oxidative DNA damage and may contribute to larynx carcinogenesis. The X-ray repair cross complementing 1 (XRCC1) and excision repair cross-complementing rodent repair deficiency, complementation group 4 (ERCC4(XPF)) genes are important components of DNA excision repair systems, which repair DNA damage induced by various factors, including...
A RECENT STUDY of head and neck cancer in Ireland (Herity et al., 1981) confirmed that tobacco and alcohol consumption were significant risk factors in the development of cancer of the larynx; a heavy smoker had a risk almost 40 times that of a non-smoker and a heavy drinker had a 3-fold increase in risk over a nondrinker. Many other workers have described similar findings (Wynder et al., 1956,...
following the first report of laryngeal small cell carcinoma in canada in 1972,only 82 cases of this cancer has been reported in the literature untill 2001.this cancer originates from laryngeal neuroendocrine cells.It,s clinical presentation consists of hoarseness,breathing difficulty:and cigarette smoking is the most important risk factor.this type of cancer is mostly presented after 50 years ...
