Using capecitabine to reduce breast cancer recurrence in high-risk patients

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

Phase 3 Interventional Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT05212454

This study is testing if the drug capecitabine can help reduce the chances of breast cancer coming back in women aged 18-70 who are at high risk after surgery.

What this trial studies

This clinical trial evaluates the efficacy of capecitabine as an adjuvant therapy for female patients aged 18-70 with hormone receptor-positive, HER2-negative breast cancer who are at high risk of recurrence after radical surgery. The study focuses on patients with specific high-risk factors, such as multiple positive lymph nodes or large tumor size. By administering capecitabine post-surgery, the trial aims to determine if this treatment can significantly lower the chances of cancer returning within the critical early years following surgery.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-70 who have undergone radical surgery for HR-positive, HER2-negative breast cancer and meet specific high-risk criteria.

Not a fit: Patients with low-risk breast cancer or those who have received prior treatment for their current breast cancer are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the risk of breast cancer recurrence in high-risk patients.

How similar studies have performed: Previous studies have indicated that adjuvant capecitabine may benefit similar patient populations, suggesting a promising approach.
