TERT and laryngeal squamous cell carcinoma: The purpose of this study was to investigate, within this ethnic group, the association between smoking status and candidate genes with roles in chromosomal maintenance (TERT: telomerase reverse transcriptase) and the carcinogenic metabolization of toxins (GSTs: the glutathione S-transferases family: GSTM1, GSTT1), and to explore their role in laryngeal squamous cell carcinoma (LSCC) development.
