Overview
compare the efficacy and safety of TCbHP and EC-THP regimen in HER2-positive breast cancer patients
Description
The objective of this study is to conduct a randomized controlled clinical study to compare the efficacy and safety of TCbHP and EC-THP regimen in HER2-positive breast cancer patients, so as to further optimize adjuvant chemotherapy regimen for breast cancer.
