Efficacy of Supplement Adjuvant Capecitabine in HR+/HER2- Breast Cancer Patients With High Risks

Efficacy and Safety of Supplement Adjuvant Capecitabine in Postoperative Hormone Receptor (HR)-Positive, Human Epidermal Growth Factor Receptor 2 (HER2)-Negative High-risk Breast Cancer Patients: a Multicenter, Single-arm Clinical Trial

According to the latest data from the World Health Organization's International Agency for Research on Cancer (IARC) for 2020, breast cancer has been the most prevalent cancer with 2.26 million new cases. Among Chinese breast cancer patients, approximately 60% are hormone receptor (HR) positive, and 80% have early-stage breast cancer. For HR-positive, human epidermal growth factor receptor-2 (HER2) negative breast cancer patients, the first peak of recurrence is about 2-3 years after surgery, especially for patients with high-risk clinical and/or pathological features. Therefore, adjuvant therapy is essential to reduce recurrence during this period.

Capecitabine is an anti-metabolite fluoropyrimidine deoxynucleoside carbamate that can be converted to fluorouracil (5-Fu) in vivo. Studies have shown that patients with HR-positive HER2-negative breast cancer with high-risk factors may benefit from postoperative adjuvant capecitabine therapy as well as patients with triple-negative breast cancer. Therefore, we assumed that additional capecitabine may reduce the reccurence of breast cancer in patients with high-risk factors.

This trial is an open, single-arm clinical trial designed to investigate the effect of additional adjuvant capecitabine therapy on recurrence and survival in HR-positive HER2-negative breast cancer patients with high-risk factors.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: capecitabine group
All enrolled cases should be given standard chemotherapy, radiotherapy and endocrine therapy according to the Chinese Society of Clinical Oncology (CSCO) guidelines for the treatment of breast cancer, with the specific regimen decided by the doctor according to the condition. After the completion of standard chemotherapy, capecitabine 1250mg/m2 should be given orally twice a day for 2 weeks of the 3-week treatment course, and the total duration of treatment is 8 courses, which can be given simultaneously with radiotherapy and endocrine therapy. Premenopausal patients may use ovarian suppressants as needed.
capecitabine, 0.5g per pill, given 1250mg/m2 twice a day for 2 weeks of the 3-week treatment course. The total duration of treatment is 8 courses.
