TREM1 and neoplasm: As a continuous variable, TREM1 expression was associated with poorer DMFS, univariately (P = 1.9x10-13), as well as in the multivariable model (P = 3.2x10-05), where it remained significant in the presence of molecular subtype, immune subclass, histologic grade, tumor size, lymph node status, ER status, patient age, and treatment status.
