Adopting the MRD Strategy to Optimize Post-operation Adjuvant Therapies for Early Stage Breast Cancer

Recruiting now · Not applicable

Conditions studied: Early-stage Breast Cancer

In brief

This study is a prospective, multi-center, open-label cohort study, with 3 years disease free survival(DFS) as the primary endpoint. We optimize post-operation adjuvant therapy for early stage breast cancer based on the MRD strategy: patients with clinical high risk or post-operation 1st MRD tested positive will receive intensive adjuvant therapy, while patients with low clinical risk and post-operation 1st MRD tested negative will receive standard adjuvant therapy, and the treatment regimens will be adjusted every 3 months according to the change of MRD status. About 100 TNBC patients, 100 HER2+ patients, and 100 ER+ patients are planned to be enrolled.
