What this trial is about
Several researches have proved that avoiding axillary surgery does not worsen the outcome of breast cancer patients with relatively low risk. Based on the routine axillary imaging evaluation (ultrasound and MR etc.) and latest dedicate lymph node PET (LymphPET), axillary nodal burden can be identified before operation. Therefore this prospective study are designed to evaluate the negative predictive value of LymphPET and to verify whether sentinel lymph node biopsy can be spared in patients with negative preoperative axillary assessment.
