INTRODUCTION Several studies have implicated Helicobacter pylori as a risk factor in laryngeal cancer, but other studies disagree. It is fundamental that the relationship between Helicobacter pylori and laryngeal cancer be verified in order to provide evidence of ways to prevent the initiation and development of this carcinoma. MATERIALS AND METHODS In(More)
OBJECTIVES To investigate the presence of Helicobacter pylori in the larynx, and to identify the relationship between H. pylori infection and laryngeal squamous cell carcinoma in a male population. METHODS This study included 59 male patients with laryngeal squamous cell carcinoma and 41 control subjects. Nested polymerase chain reaction and target(More)
microRNA93 (miR-93) is expressed in the miR‑106b-25 cluster, located in intron 13 of the MCM7 gene. Our previous study found that miR-93 was significantly upregulated in laryngeal squamous cell carcinoma (LSCC), and cyclin G2 (CCNG2) was a potential target of miR-93 in LSCC. However, the possible functions and molecular mechanisms of miR-93 in LSCC remain(More)
The compositions and abundances of the microbiota in the ecological niche of the human throat and the possible relationship between the microbiota and laryngeal cancer are poorly understood. To obtain insight into this, we enrolled 27 laryngeal carcinoma patients and 28 subjects with vocal cord polyps as controls. For each subject, we simultaneously(More)
This study was aimed to examine the prognostic value of preoperative neutrophils, platelets, lymphocytes, monocytes and calculated ratios in patients with laryngeal squamous cell cancer (LSCC). From January 2007 to December 2011, 979 patients with LSCC were enrolled in our study. Preoperative neutrophils, platelets, lymphocytes, monocytes,(More)
The pharynx is an important site of microbiota colonization, but the bacterial populations at this site have been relatively unexplored by culture-independent approaches. The aim of this study was to characterize the microbiota structure of the pharynx. Pyrosequencing of 16S rRNA gene libraries was used to characterize the pharyngeal microbiota using swab(More)
The microbial communities that inhabit the laryngeal mucosa build stable microenvironments and have the potential to influence the health of the human throat. However, the associations between the microbiota structure and laryngeal carcinoma remain uncertain. Here, we explored this question by comparing the laryngeal microbiota structure in laryngeal cancer(More)
