In this study, we investigated the expression profiles of a panel of plasma lncRNAs—BCO40584, AK58003, HOTAIR, CCAT1, CCAT2, MALAT1, PVT1, promoter of CDKN1A antisense DNA damage activated RNA (PANDAR), urothelial cancer associated 1 (UCA1), and sprouty RTK signaling antagonist 4-intronic transcript 1 (SPRY4-IT1) and the genes SNCG and BDNF in metastatic and non-metastatic BC cases compared with their expressions in benign breast diseases and healthy controls to identify the lncRNAs specifically associated with BC. This evidence concerns the gene CDKN1A and breast cancer.
