Precise lymph node biopsy system for breast cancer treatment

Clinical Study on Regularity of Lymphatic Drainage and Surgical Treatment of Breast Cancer

Not applicable Interventional Shandong University · NCT03857932

This study is testing a new way to do lymph node biopsies for early-stage breast cancer to see if it can improve surgery results and reduce complications compared to the standard method.

What this trial studies

This clinical trial focuses on improving the sentinel lymph node biopsy (SLNB) technique for patients with early-stage breast cancer by utilizing preoperative computed tomographic lymphography. The study aims to accurately identify sentinel lymph nodes and their drainage patterns to enhance surgical outcomes and minimize unnecessary lymph node removals. Participants will be randomized into two groups: one receiving the precise SLNB with additional non-sentinel lymph node resection, and the other receiving standard SLNB. The goal is to reduce treatment-related complications while ensuring effective cancer management.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed early-stage breast cancer who have abnormal para-sentinel lymph nodes but negative fine needle aspiration cytology results.

Not a fit: Patients with ductal carcinoma in situ or those who have received neo-adjuvant therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more precise surgical interventions and better outcomes for breast cancer patients.

How similar studies have performed: Other studies have shown promise in improving SLNB techniques, but this specific approach utilizing computed tomographic lymphography is relatively novel.
