P2-18-03: Systemic Adjuvant Treatment of T1a and T1b N0M0 HER2+ Breast Carcinomas; an AERIO/UNICANCER Study

Management of Small T1a/b N0 Breast Cancers

T1ab N0 breast cancer generally has excellent prognosis. Adverse prognostic factors include HER2+ disease, ER-negative disease, high-grade histology, T1b, and young age of patient. These patients are largely excluded from most trials, and to date, no prospective studies for this group yet reported. Treatment guidelines are vague and treatment inconsistent. As yet, in the HER2+ population, little experience with targeted therapy has been reported. Prospective trials are needed.
