BACKGROUND From among a cohort of 65,553 men aged 30-84 in Karunagappally Taluk, Kerala, India, 52 hypopharyngeal cancer cases and 85 laryngeal cancer cases were identified by the Karunagappally Cancer Registry during the period between 1990 and 2009. METHODS We conduct Poisson regression analysis of grouped data, taking into account age and education. RESULTS This study showed that the inc...

BACKGROUND A role for diet in laryngeal carcinogenesis has been suggested, but only a few studies have examined the potential relationship with a wide variety of macronutrients. PATIENTS AND METHODS A case-control study was conducted between 1992 and 2000 in Italy and Switzerland, including 527 incident cases of laryngeal cancer, and 1297 controls hospitalized for acute, non-neoplastic condit...

The altered expression of the prolactin receptor (PRLR) has been associated with the development of various types of cancer, particularly breast, prostate and endometrial cancer. However, in laryngeal tumors, the expression of PRLR has not yet been documented. The aim of this study was to determine the expression and localization of PRLR in laryngeal cancer (LC) in comparison with recurrent res...

Laryngeal carcinoma is the 11th commonest form of cancer in men world-wide, with 121,000 new cases in 1985. More than 95% of all laryngeal malignancies are squamous cell carcinomas. Treatment indications in cancer of the larynx are often controversial, since there are few comparative studies of different available therapeutic approaches. Surgery and radiotherapy are both widely used, and the ch...

The present study aimed specifically investigate the expression and correlation of kelch-like ECH-associated protein‑1 (KEAP1), nuclear factor (erythroid-derived 2)‑like 2 (NRF2), quinone oxidoreductase‑1 (NQO‑1) and heme oxygenase‑1 (HO‑1) in laryngeal cancer and their association with clinicopathological features. A total of 33 paired human fresh advanced laryngeal cancer and adjacent normal ...

PURPOSE This study was designed to add new data about laryngeal carcinogenesis, a multistep process in which chemical and/or viral agents induce and promote successive alterations in growth factor-linked signal transmission pathways, genetic instability, and mutations in key genes involved in cell growth control. Epidemiological evidence suggests that human papillomavirus (HPV) infection may be...

OBJECTIVE This study aimed to understand the relationship between tissue factor (TF) and laryngeal carcinoma. METHODS Differences in TF expression between pericarcinomatous and carcinomatous tissues were studied in patients with laryngeal carcinoma; the potential clinical significance of the observed differences is discussed. Immunohistochemical, western blot, and RT-PCR analyses were perform...

INTRODUCTION Laryngeal tuberculosis used to be a common complication in advanced pulmonary tuberculosis. However, it has become a rare occurrence in developed countries since the introduction of antituberculous agents. Moreover, the pattern of the disease has changed over the years. Nowadays, it more closely resembles a laryngeal carcinoma than any other laryngeal illness. CASE PRESENTATION W...

Laryngeal cancer is approximately the twentieth most common cancer in the world with more than 150,000 new cases diagnosed annually. Laryngeal cancer, a prognostic serious disease associated with high mortality, is one of the most debilitating forms of cancer. Despite advances in therapy and novel surgical and non-surgical approaches, early diagnosis remains the best predictor of survival. Alth...

Alcohol intake is positively associated with the risk of upper aerodigestive tract (UADT) cancers; but its effect on gastric or colorectal cancer is controversial. Previous study had identified several single nucleotide polymorphisms (SNPs) of Alcohol Dehydrogenase (ADH) genes associated with UADT cancers in European and Japanese populations. We sought to determine if these SNPs associated with...
