Breast-Conserving Therapy in Patients With Triple-Negative Breast Cancer

RATIONALE: Triple-negative breast cancer (TNBC) is an aggressive subtype shown to have a high risk of locoregional recurrence (LRR) and distant metastasis (DM). The equivalent impact of breast-conserving therapy (BCT) and mastectomy on disease-free survival in patients with early breast cancer has been established by a number of large randomized controlled trials and meta-analysis. However, ongoing dispute exists on whether TNBC is a good candidate for BCT. PURPOSE: This prospective, randomized, open, single-center Phase III clinical study is conducted to compare efficacy and safety of breast-conserving therapy and mastectomy in treating Chinese patients with early TNBC.
