Abstract

The role of microRNAs (miRs) as possible biomarkers and therapy targets has been extensively investigated in a number of types of cancer. However, the aberrant expression of miRs in laryngeal squamous cell carcinoma (LSCC), particularly during the progression of the disease, is poorly understood. In the present study, the role of miRs as possible novel early pre‑diagnostic biomarkers of LSCC was investigated. TaqMan probe stem‑loop quantitative polymerase chain reaction was utilized to accurately measure the amount of miR‑148a and miR‑375 in clinical samples of mild dysplasia, moderate dysplasia, severe dysplasia, cancer in situ, laryngeal cancer and normal epithelial controls. The application of miR‑148a and miR‑375 as potential predictive biomarkers for early diagnosis of LSCC was analyzed. The results of the present study suggested that miR‑148a and miR‑375 were significantly upregulated in LSCC tissues, and increased expression of miR‑375 was associated with a more aggressive phenotype of LSCC. Additional investigation revealed that miR‑148a and miR‑375 increased during different dysplasia stages of LSCC carcinogenesis, and high‑level expression of miR‑148a or miR‑375 in patients with laryngeal dysplasia may predict subsequent malignant transformation. miR‑148a and miR‑375 were significantly upregulated during LSCC carcinogenesis and may serve as possible predictive biomarkers for early diagnosis of LSCC.
