Background and study aims
Axillary lymph node evaluation is one of the important indicators for clinical pathological staging of breast cancer. However, for patients receiving neoadjuvant chemotherapy, the timing of sentinel lymph node biopsy is still controversial. This study will investigate the feasibility and safety of sentinel lymph node biopsy in Chinese patients with cN1 breast cancer who undergo routine radical surgery after neoadjuvant chemotherapy under current medical conditions in China
Who can participate?
Eligible patients with cN1 breast cancer at 18-70 years of age of either sex
What does the study involve?
All enrolled patients will undergo neoadjuvant chemotherapy, radical mastectomy and intraoperative sentinel lymph node biopsy. All enrolled patients will receive this treatment and undergo lymph node diagnosis and evaluation after surgery
What are the possible benefits and risks of participating?
Eligible patients included in this study may not get direct benefits, but they will get more medical attention from investigators. Lymph node tracers methylene blue and carbon nanoparticles can cause local skin necrosis, but this risk can be avoided by rigorous intraoperative operation
Where is the study run from?
1. The First Hospital of China Medical University (lead center)
2. Shengjing Hospital of China Medical University
3. Liaoning Cancer Hospital & Institute
4. Affiliated Zhongshan Hospital of Dalian University
5. The Second Hospital of Dalian Medical University
6. The Fourth Affiliated Hospital of China Medical University, China.
When is the study starting and how long is it expected to run for?
The anticipated start date of this study is December 2019 and the anticipated end date of this study is February 2022. The duration of the trial is approximate 2 years.
Who is funding the study?
This study will be funded by Liaoning Province Distinguished Professor Fund (LWF [2017] No.3)

| Scientific title | Feasibility of sentinel lymph node biopsy using dye alone method in Chinese patients with cN1 breast cancer after neoadjuvant chemotherapy evaluated by clinical physical examination and three-dimensional ultrasound: a prospective, multicenter, diagnostic trial |
| Study objectives | For patients receiving neoadjuvant chemotherapy, the timing of sentinel lymph node biopsy is still controversial. Although some results have been achieved in this respect, the results also have some limitations. Based on this, this study will investigate the feasibility and safety of sentinel lymph node biopsy in Chinese patients with cN1 breast cancer who undergo routine radical axillary lymph node dissection after neoadjuvant chemotherapy under current medical conditions in China |
| Ethics approval(s) | Approved 06/08/2019, Medical Ethics Committee, First Hospital of China Medical University (No.155 Nanjing North Street, Heping District, Shenyang, Liaoning Province, China; yykyk@vip.163.com; +86-024-83282837), ref: KLS[2019]2019-193-2 |
| Health condition(s) or problem(s) studied | Breast cancer |
| Intervention | The enrolled patients will receive neoadjuvant chemotherapy. After neoadjuvant chemotherapy and before radical axillary lymph node dissection, sentinel lymph node tracer will be injected. Before routine axillary lymph node dissection, sentinel lymph node biopsy will be performed. The dissected sentinel lymph nodes and other axillary lymph nodes will be marked separately for routine pathological examination. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | False negative rate of sentinel lymph node biopsy at postoperative day one, according to pathological results and referencing to gold standard, false negative rate of sentinel lymph nodes = (number of patients having false negative sentinel lymph nodes/number of patients having gold standard results) ×100% |
| Secondary outcome measures | 1. At postoperative day one, the relationship between each influential factor (neoadjuvant efficacy, tumor location, surgical procedure, number of sentinel lymph nodes detected, molecular subtypes of breast cancer (luminal A, luminal B, HER2-positive, triple-negative)) and the results of sentinel lymph node biopsy after neoadjuvant chemotherapy 2. Adverse events during the trial |
| Overall study start date | 01/03/2019 |
| Completion date | 20/02/2022 |
