The prognostic significance of preoperative tumor marker (CEA, CA15-3) elevation in breast cancer patients: data from the Korean Breast Cancer Society Registry

Abstract

Preoperative CEA and CA15-3 levels showed varying prognostic ability according to breast cancer subtype. Preoperative CA15-3 and CEA elevation are significant prognostic factors for luminal breast cancer, but they were not significant factors for TNBC.
