研究设计:

单臂 

Study design:

Single arm 

研究目的:

验证初治淋巴结阳性而新辅助化疗后临床降期满意的浸润性乳腺癌患者,采用TAD手段(标记定位阳性淋巴结,双示踪法前哨淋巴结显影)进行淋巴结活检,若结果为ypN0,可以安全地免除腋窝淋巴结清扫,从而尽可能减少手术损伤,保证这部分患者生活质量。  

Objectives of Study:

To verify that the patients with invasive breast cancer who are initially diagnosed with positive lymph nodes and who are satisfied with the clinical decline after neoadjuvant chemotherapy, lymph node biopsy is performed by TAD (labeling positive lymph nodes, double tracer sentinel lymph node imaging). If the result is ypN0, axillary lymph node dissection can be safely exempted, so as to minimize the surgical injury and ensure the quality of life of these patients.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄18-70岁,空心针穿刺病理确诊的浸润性乳腺癌患者;
2.肿瘤分期cT1-3N1-2M0期,治疗前病理确诊(CNB或FNA)腋窝淋巴结转移癌;
3.化疗前腋窝淋巴结标记夹进行标记,按计划行完成新辅助化疗,化疗后临床腋窝降期满意;
4.成功接受TAD手术,术后病理结果提示腋窝淋巴结病灶病理完全缓解者;
5.自愿参加本试验,签署知情同意书。

Inclusion criteria

1. Patient between 18 and 70 years of age, invasive breast cancer confirmed by core biopsy; 2. cT1-3N1-2M0, axillary node positivity confirmed by core biopsy or needle cytology; 3. Placement of a clip in the proven positive axillary node befor NACT and converted to cN0 after NACT; 4. TAD successfully performed and pathology shows pN0; 5. Signed the informed consent form.

排除标准:

1.治疗前未病理诊断腋窝淋巴结转移者; 2.炎性乳腺癌患者及伴随远处转移者; 3.化疗前腋窝淋巴结未使用标记夹进行标记,未行新辅助化疗或新辅助化疗后临床腋窝降期不满意者; 4.新辅助化疗后未按要求接受TAD或TAD结果显示腋窝淋巴结有肿瘤残余者; 5.身体条件不能完成该研究,或者有其他精神、心理因素不能参加该研究者; 6.怀孕或哺乳期妇女; 7.拒绝签署知情同意书者.

Exclusion criteria:

1. Axillary node positivity not pathologically confirmed before NACT; 2. Inflammatory breast cancer or M1 disease at presentation; 3. No clip placed befor NACT or remains cN1 after NACT; 4. TAD unsuccessful or pathology shows pN+; 5. Other physical or mental conditions deemed unfit for the study; 6. Pregnant or lactating women; 7. Informed consent form not signed.
