Table 2. Correlations between expression of selected miRNAs in blood of BC patients at pre-RT control and post-RT.

	Pre-RT control			Post-RT
	miRNA-146a	miRNA-155	miRNA-221	miRNA-146a	miRNA-155	miRNA-221
miRNA-155	0.927^**			0.924^**
miRNA-221	0.900^**	0.917^**		0.896^**	0.909^**
miRNA-222	0.890^**	0.910^**	0.930^**	0.882^**	0.906^**	0.922^**

BC, breast cancer; RT, radiotherapy; miRNA, microRNA.

miRNA expression was calculated as log(2-DCt)+3. Pearson correlation coefficient (r) is shown.

**means significant differences at p<0.01 (bilateral).
