Prognostic stratification of oestrogen receptor‐positive <scp>HER</scp>2‐negative lymph node‐negative class of breast cancer

Abstract

Current routinely assessed variables can provide additional prognostic information in LN^- /ER⁺ /HER2^- BC. The proposed (Nottingham Px) index can stratify the BC clinically indeterminate group of patients into excellent and poor prognostic subgroups and can be used to identify reliably patients for systemic chemotherapy or further multigene prognostic testing. Performance of prognostic variables in these tumours is time-dependent, and should be considered in future studies.
