Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In addition to the axillary lymph nodes, the internal mammary lymph nodes (IMLNs) drainage is another important lymphatic channel of the breast. The status of IMLNs also provides important prognostic information for breast cancer patients. The technical evolvements of sentinel lymph node biopsy (SLNB) and lymphoscintigraphy provided a less invasive method for assessing IMLNs than surgical dissection. Recently, many study concerning IMSLNB was performed in the patients with clinically negative axillary nodes. However, previous published studies concerning patients with breast cancer who all underwent a radical mastectomy have shown that IMLN metastases are mostly found concomitantly with axillary metastases. For this reason, IM-SLNB is even more important for clinically axillary node-negative patients. To our knowledge, this is the first attempt of the IM-SLNB in early breast cancer patients with clinically positive axillary nodes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES:

* Determine the impact of routinely performed internal mammary sentinel lymph node biopsy on the systemic and locoregional treatments plan.
* Evaluate the metastasis rate of internal mammary sentinel lymph nodes in patients with clinically axillary node-positive.
* Draw the learning curve of internal mammary sentinel lymph node biopsy.

OUTLINE:

3\~18 hours before surgery, under ultrasonographic guidance, 0.5\~1.0 mCi 99mTc-labeled sulfur colloid in sterile saline (total volume 0.2\~2.0 mL) is injected intraparenchymally into 2 quadrants of breast. Subsequently, lymphoscintigraphy is performed 0.5\~1.0 hour before surgery. internal mammary sentinel lymph node biopsy is performed during the surgery and the internal mammary sentinel lymph nodes were sent to histologic examination.

clinically positive axillary nodes

3\~18 hours before surgery, under ultrasonographic guidance, 0.5\~1.0 mCi 99mTc-SC in sterile saline (total volume 0.2\~2.0 mL) is injected intraparenchymally into 2 quadrants of breast. Subsequently, LSG is performed 0.5\~1.0 hour before surgery. Methylthioninium was injected intraparenchymally. IM-SLNB is performed during the surgery and the IMSLNs were sent to histologic examination
