Brief 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.

ACTIVE COMPARATOR

conventional technique: 99mTc-labeled Sulfur Colloid was injected into the tumor quadrant 3-24 hours before surgery, lymphoscintigraphy was performed 30min before surgery. Four milliliters of methylthioninium was injected subcutaneously above the primary tumor or around the biopsy cavity 10 min before surgery. Axillary sentinel lymph node biopsy and Internal mammary sentinel lymph node biopsy was performed during surgery. Axillary lymph node dissection was performed if ASLN was positive.

EXPERIMENTAL

modified technique: 99mTc-labeled Sulfur Colloid was injected into 2 quadrants of the breast 3-24 hours before surgery, lymphoscintigraphy was performed 30min before surgery. Four milliliters of methylthioninium was injected subcutaneously above the primary tumor or around the biopsy cavity 10 min before surgery. Axillary sentinel lymph node biopsy and Internal mammary sentinel lymph node biopsy was performed during surgery. Axillary lymph node dissection was performed if ASLN was positive.

Interventions

Control Group: Each patient received the 1 intraparenchymal injection of 99mTc-SC (0.5\~1.0 mCi/0.5mL) in the tumor quadrant. Study Group: Two syringes of 0.25\~0.5 mCi 99mTc-SC in 0.2\~1.0 mL volume were injected intraparenchymally into 2 quadrants of breast, at the 6 and 12 o'clock positions.
