Abstract

Abstract: Objective To evaluate the detection rate,accuracy rate,and false negative rate of axillary sentinel lymph node biopsy (SLNB) after neoadjuvant chemistry (NAC) in axillary lymph node (ALN) clinical node negative (cN0) patients examined by physical examination,breast ultrasound,and breast magnetic resonance imaging (MRI),and discuss the feasibility of ASLNB after NAC.Methods Seventy-four cases of breast cancer admitted to the Department of Surgery Oncology,Provincial Clinical Institute,Fujian Medical University from August 2013 to July 2016 were enrolled in the study for retrospective analysis.All of the patients receiving NAC were divided into three groups according to the results of physical examination,breast ultrasound,and MRI.There were 55 cN0 cases judged by physical examination and breast ultrasound (group A),50 cyN0 cases by additional breast MRI (group B),and 24 clinical node positive (cN+) cases by all the three examination techniques (group C).Results In group A,the clinical remission rate of ALN was 74.3%,and the successful rate,accuracy rate,and false negative rate of ASLNB were 100%,92.7%,and 9.7%,respectively.In group B,the above indicators were 67.6%,100%,94.0%,and 7.8%,respectively.The cN+ patients in group C were given axillary lymph node dissection (ALND).The false negative rate of ASLNB had no significant difference (P>0.05) between group A and group B.Conclusion SLNB can replace ALND for the patients whose ALN transformed to cN0 from cN+ after NAC by physical examination and breast ultrasound.The false negative rate can be further decreased with additional MRI.MRI can be used to judge ALN in breast cancer patients after NAC.
