Objective: To evaluate the clinicopathologic findings and treatment outcome in laryngectomized patients with laryngeal cancer and hypopharyngeal cancer. Materials and Methods: The authors retrospectively reviewed the medical records of 212 patients who had been newly diagnosed and treated with laryngectomy between January 2000 and December 2010. The age, gender, clinical manifestations, associa...

PURPOSE This study was conducted to explore the effects of genetic polymorphisms (CYP1B1*2 G355T, CYP1B1*3 C4326G, and CYP2E1*5 G-1293C) and environmental factors (smoking and drinking) on susceptibility to laryngeal cancer in a Han Chinese study group. METHODS This case-control study included 552 Han Chinese patients diagnosed with laryngeal cancer and 666 healthy control subjects of the sam...

IntroductionLife expectancy is rising and consequently also the number of older patients with head neck cancer. Different treatment regimens are often applied for patients. The aim this study to investigate how patterns survival rates have changed over past 20 years in squamous cell carcinoma (HNSCC).MaterialsPatient tumour characteristics, 5-year data from Netherlands Cancer Registry aged ≥60 ...

Laryngeal cancer is the most frequent neoplasm in the head and neck region, with the vast majority of tumors originating from squamous cells. The survival rate of patients with laryngeal cancer has not improved substantially over the past 25 years. To acquire further knowledge regarding the molecules responsible for laryngeal cancer oncogenesis and, in turn, to improve target therapy iTRAQ and ...

BACKGROUND A number of molecular epidemiological studies have been conducted to explore the association of human papillomavirus (HPV) infection with laryngeal cancer. However, the findings are heterogeneous. METHODS We systematically reviewed studies on HPV infection and laryngeal cancer published up to 15 May 2012 and quantitatively summarized the prevalence of HPV infection and its associat...

DNA topoisomerase II-α (Topo II-α) is essential for numerous cell processes, including DNA replication, transcription, recombination, and chromosome separation and condensation. Altered Topo II-α expression may lead to carcinogenesis and cancer progression. The aim of the present study was to investigate the association between Topo II-α expression levels and clinicopathological data from laryn...

Cancer-associated fibroblasts (CAFs) play a crucial role in cancer progression and even initiation. However, the origins of CAFs in various cancer types remain controversial, and one of the important hypothesized origins is through epithelial-mesenchymal transition (EMT) from cancer cells. In this study, we investigated whether the HEp-2 laryngeal cancer cells are able to generate CAFs via EMT ...

A multicenter case-control study was conducted during 1999-2002 in four European countries (Poland, Romania, Russia, and Slovakia) to evaluate the role of occupational exposures in risk of laryngeal/hypopharyngeal cancer. Male cancer cases (34 hypopharyngeal, 316 laryngeal) with full data on occupational history and nonoccupational factors were compared with 728 hospital controls for occupation...

OBJECTIVE To investigate the protein expression of matrix metalloproteinase 2 (MMP2) and its clinical significance in laryngeal cancer. METHODS A comprehensive search for the related literature published in China and other countries was conducted in a variety of databases, including MEDLINE, Embase, China Academic Journals Full-text Database, Wanfang Data and VIP Database. A total of seven ca...
