Abstract
BACKGROUND: Laryngeal cancer is one of the most common malignancies in the head and neck. Activated platelets play a critical role in cancer development and progression. Altered mean platelet volume (MPV) and platelet distribution width (PDW) have been found in various types of cancer. The purpose of the current study was to investigate the association of platelet indices with laryngeal cancer. STUDY DESIGN: The study included 216 patients with laryngeal cancer, 189 subjects with benign laryngeal disease, and 213 control subjects between January 2015 and December 2015. All participants' clinical and laboratory characteristics at initial diagnosis were collected. RESULT: MPV was significantly lower and PDW was markedly higher in laryngeal cancer patients compared with control subjects and patients with benign laryngeal disease. A significant correlation between MPV and lymph node metastasis was found. The prevalence of laryngeal cancer increased as MPV quartiles decreased and PDW quartiles increased. Furthermore, MPV and PDW were independent risk factors for distinguishing laryngeal cancer from benign laryngeal disease. CONCLUSIONS: The patients with laryngeal cancer have reduced MPV and increased PDW compared to the subjects without laryngeal cancer. In addition, MPV and PDW play different roles in laryngeal cancer from benign laryngeal disease.
