作者： Xiuchun Chen Zhenduo Lu Chengzheng Wang Minhao Lyu Jianghua Qiao Xianfu Sun Lianfang Li Chongjian Zhang Zhenzhen Liu Department of Breast Disease The Affiliated Cancer Hospital of Zhengzhou University&Henan Cancer HospitalZhengzhouHenan 450008China

Background:Sentinel lymph node(SLN)biopsy is gradually accepted as the standard of care in breast cancer patients with down-staged axillary disease after neoadjuvant chemotherapy(NAC).However,it is still difficult to precisely define pre-NAC clinical node-positive(cN1)and post-NAC clinical node-negative(ycN0).This prospective single-center trial was designed to evaluate the feasibility and accuracy of standard targeted axillary dissection(TAD)after NAC in highly selective pre-NAC cN1 patients(not considering ultrasound-based axillary ycN staging).Methods:This prospective trial included patients with initial pre-NAC cT1-3N1M0 invasive breast cancer but with a rigorous definition of cN1 from the affiliated cancer hospital of zhengzhou *** NAC was effective(including complete and partial responses)and preoperative axillary palpation was negative,preoperative ultrasound-based axillary staging was not considered,and all patients underwent TAD followed by axillary lymph node(LN)*** detection rate(DR)and false-negative rate(FNR)of TAD were ***:A total of 82 patients were included,and 77 of them were eligible for data *** DR for TAD was 94.8%(73/77).There were 26 patients with one abnormal LN at the time of diagnosis based on ultrasound,45 patients with two,and 2 patients with *** patient had one TAD LN,four patients had two TAD LNs,and 68 patients had three or more TAD *** axillary palpation yielded negative results for all 73 patients who successfully underwent *** ultrasound-based ycN0 and ycN+conditions were detected for 52 and 21 cases,*** FNR was 7.4%(2/27)for standard TAD(≥3 SLNs),which was lower than that of all successful TAD(≥1 SLN;10.0%,3/30).Conclusions:In rigorously defined pre-NAC cN1 breast cancer patients,standard TAD is feasible for those with negative axillary palpation after NAC,and FNR is also less than 10%.Registration:***,ChiCTR2100049093.
