研究概览
简要总结
The goal of this clinical research study is to learn if it is feasible to use find (using ultrasound) and surgically remove cancer that has spread to the lymph nodes, during routine lymph node surgery.
In standard care, all affected lymph nodes are removed. In this study, however, the cancerous lymph nodes will be removed separately and then the rest of the lymph nodes under the arm will be removed after that.
详细描述
Before surgery, patient may or may not receive the standard chemotherapy drug(s) that their doctor recommends. If patient's doctor suggests chemotherapy before surgery, they will be asked to sign a separate consent form that describes the chemotherapy and its risks.
On the day of surgery, patient will have an ultrasound of their lymph nodes. If patient has received chemotherapy before their surgery, they will have a fine needle aspiration (FNA) of any abnormal lymph nodes either right before or during their standard breast and underarm surgery. The abnormal lymph nodes will be marked for the surgeon to remove using standard techniques with either ultrasound, a mammogram, or 125I-seed placement. To perform an FNA, the area is numbed with anesthetic and a needle is inserted into the affected area so that cells can be collected. Ultrasound imaging is used to guide the needle into the area. The cells will be used for research to learn if the chemotherapy killed the abnormal lymph node cells.
Patient will have standard breast and underarm surgery (underarm lymph node removal and either a partial mastectomy or total mastectomy with or without reconstruction). Patient's doctor will discuss the surgery with patient in more detail and patient will be asked to sign a separate consent form.
During this surgery, the 1 or 2 abnormal underarm lymph nodes found by ultrasound will be removed and sent as separate samples before the rest of the underarm lymph nodes are removed.
Patient's study participation will be complete after surgery.

结局指标
主要结局
Verification of Axillary Node Metastases Using Ultrasound Imaging Before and After Guided Excision
时间窗: 1 day
Patients required to have a minimum of at least two nodal ultrasounds: once at diagnosis and once prior to surgery. Marker clip placed in the one or two abnormal node(s) at diagnosis and on day of surgery. Nodes localized by ultrasound (or by mammographic or 125I-seed localization if not visualized well with ultrasound) for excision, and fine needle aspiration (FNA) repeated of previous abnormal nodes. Patients undergo standard breast and axillary surgery. During surgery the one or two abnormal axillary nodes identified by ultrasound are removed. The lymph nodes excised with the clip will be evaluated with specimen x-ray. If no marker clip is identified in the lymph node(s), the axillary contents will be x-rayed to document removal of the marker clip. Procedure considered a success if all marker clips are successfully identified in the preoperative ultrasound and documented in a lymph node via postoperative specimen x-ray of the excised material.
