Internal Mammary Sentinel Lymph Node Biopsy in Early Breast Cancer Patients With Clinically Axillary Node -Negative

Summary

In addition to the axillary lymph node, the internal mammary lymph node (IMLN) chain is also the first-echelon nodal drainage site for metastasis and provides important prognostic information in breast cancer patients. The internal mammary sentinel lymph node biopsy (IM-SLNB) provides a less invasive method of assessing the IMLN than surgical dissection. But the low visualization rate of IMSLN has been a restriction of IM-SLNB. This clinical trial is carried out to improve the visualization rate of IMSLN with modified techniques: (1) The radiotracer is injected intraparenchymally into 2\~4 quadrants of breast. (2) The radiotracer is injected in a high volume. (3) The radiotracer should be injected under ultrasonographic guidance.
