Abstract

Radiation‑induced normal tissue toxicity is a common acute and chronic outcome of radiotherapy (RT) for prostate cancer (PCa). There are currently no existing pre‑assessments before treatment to predict acute and late RT‑induced toxicity. Novel predictive blood biomarkers in radiation oncology may improve treatment decision‑making and therapeutic monitoring for patients with PCa. A comprehensive systematic search of microRNA (miRNA/miR) profiling studies published in PubMed, Science Direct and Google Scholar was performed. The present systematic review, supported by meta‑analysis, summarises key findings and discusses the results of prospective clinical studies investigating miRNA expression levels and their association with RT‑induced toxicity in PCa. Out of seven clinical studies, six highlighted levels of 10 miRNAs changing in plasma, serum or peripheral blood mononuclear cells during RT. The post‑RT expression levels of miRNA‑132‑5p, miRNA‑1‑3p, miRNA‑410 and miRNA‑221 were increased, and miRNA‑23a‑3p expression was decreased among patients with low‑grade RT‑induced toxicity. Furthermore, in patients with high‑grade RT toxicity, miRNA‑197‑3p, miRNA‑151a‑5p, miRNA‑18b‑5p, miRNA‑99a and miRNA‑21 expression was increased, while miRNA‑132‑5p expression was decreased. The present miRNA meta‑analysis could be the focus of future studies to identify their potential clinical value as PCa biomarkers and therapeutic mediators in RT‑induced toxicity. The variations in miRNA levels post‑RT could be used as predictive biomarkers of RT‑induced toxicity. However, further extensive validation is required to establish the relationship between miRNA expression levels and RT‑induced toxicity in PCa and to confirm their predictive value.
