Triple-negative breast cancer（TNBC） accounts for 10% to 20% of breast cancer. TNBC is more likely to show lymph node involvement at diagnosis, and biologically more aggressive. Women with TNBC have a higher rate of distant recurrence at early-stage and a worse 5-year prognosis than women of other molecular types. Although PARP inhibitors and immune checkpoint inhibitors are showing promise to patients with advanced TNBC, however, these targeted therapies and immunotherapy for TNBC can not increase the clinical benefits of early-stage patients.~As adjuvant therapy for hepatocellular carcinoma after curative liver resection, a multicentre study demonstrated a significant prolongation of RFS and reduced extrahepatic recurrence in Huaier group. Retrospective studies have shown that Huaier granules can improve the rates of disease-free survival（DFS） and overall survival（OS）, and reduce the incidence of adverse events among operable patients with TNBC.~In this study, 1072 high-risk early-stage triple-negative invasive ductal carcinoma participants (536 cases in the observation group and 536 cases in the control group) from 30 research centers will be included. The block randomization was adopted, participants will be randomly divided into the experimental group (Huaier granule plus conventional treatment/visit) and control group (conventional treatment/visit only). All participants will be followed up for 5 years, including 2-year treatment follow-up and 3-year survival follow-up. During the treatment period, the participants will be followed up every 3 months, and the survival follow-up period will be followed up every 6 months.
This is a prospective, multicenter, randomized, parallel controlled, open-label study. The primary purpose of this study is to evaluate the efficacy of Huaier Granule on postoperative adjuvant therapy of high-risk early-stage triple-negative invasive ductal carcinoma. The Secondary purposes are to evaluate the safety of long-term use of Huaier granules as postoperative adjuvant treatment of high-risk early-stage triple-negative invasive ductal carcinoma, and the changes of quality of life score after treatment with Huaier granule.
