Studies with fewer than 20 BC instances have been excluded. Even though these signatures mostly reflect higher amounts of circulating miRNAs, some miRNAs are detected at reduced levels in blood samples of BC sufferers. Blood collection was performed ahead of surgery unless otherwise indicated. miRNAs shown in bold indicate a recurrent presence in no less than 3 independent research.
