Aim: To evaluate the correlation between microRNA (miRNA) expression and 18F-fluorodeoxyglucose (18F-FDG) uptake in breast cancer patients, focusing on the tumor-suppressor miRNAs miR-22, miR-140, and miR-328, and their potential as diagnostic biomarkers.
Material and Methods: Biopsies from 14 female breast cancer patients were analyzed, including both tumor and adjacent healthy tissues. The expression levels of miR-22, miR-140, and miR-328 were quantified using real-time PCR. SUVmax values from PET/CT imaging were obtained to assess metabolic activity in tumor tissues. Statistical analyses were performed to explore correlations between miRNA expression and PET/CT results.
Results: Our patients’ ages ranged from 38 to 74 years, with a mean of 59.5 years. The levels of miR-22, miR-328, and miR-140 were significantly lower in breast cancer tissues compared to healthy tissues. However, no statistically significant correlations were found between miRNA values and 18-FDG PET/CT SUVmax values.
Discussion: While miR-22, miR-140, and miR-328 show promise as potential diagnostic biomarkers for breast cancer due to their significant downregulation in tumor tissues, their expression does not correlate with metabolic activity as measured by SUVmax in PET/CT imaging. Further research is needed to explore the clinical applications of miRNAs in breast cancer diagnosis and prognosis.
