Outline of Final Research Achievements

The purpose of this study is to develop a simple in vitro diagnostic kit aiming at clinical application of TP53 signature.
Probe set of TP53 signature for nCounter was created. TP53 signature data was obtained from the early stage breast cancer cohort (n = 174). Univariate and multivariate analysis results revealed that TP53 signature is the most relevant factor to RFS. In addition, comprehensive gene expression analysis was performed, and the prognostic potential of TP53 signature was compared with Mammaprint, Oncotype DX, and PAM 50. It was shown that TP53 signature had the highest prognostic predictability.
