Overview

Background:
Radiotherapy plays a key role in the treatment of squamous cell head and neck cancers (HNSCC). The effectivity of radiation therapy is often limited by radioresistance of these tumours. microRNAs (miRNAs) are endogenous, evolutionary conserved, small non-coding RNAs involved in regulation of cellular processes associated with radioresistance. The objective of this study was to identify miRNA profile enabling to predict the radiation treatment outcomes in HNSCC patients.

Material and Methods:
The retrospective study included HNSCC patients who underwent a definitive radiotherapy. Patients were divided into two groups according to loco-regional control (LRC) as follows – short LRC (n = 22; median 5.1 months (min. 1.3, max, 18.6)) vs. long LRC (n = 21; 60.4 (min. 46.8, max. 98.8)) group. Global miRNA expression profiles were obtained by use of Affymetrix microarray technology (GeneChip miRNA 4.0 Array).

Results:
We identified 24 miRNAs to be significantly associated with LRC (p < 0.05), all of these miRNAs were upregulated in patients with short LRC. Out of these miRNAs, 12 miRNAs with p < 0.025 and 4 miRNAs with p < 0.01 have been identified.

Conclusion:
miRNAs seems to be promising as potential biomarkers predicting radiotherapy treatment outcomes in patients with HNSCC.
