简要总结
NAUTILUS study is a prospective, multicenter, RCT. Clinically T1,T2, node negative BCS candidates with no evidence of metastases in AUS are 1:1 randomized into no SLNB group and SLNB group.
NAUTILUS study aim to establish the minimally invasive treatment of breast cancer by reexamining the necessity of sentinel lymph node biopsy among patients with invasive breast cancer who have tumors under 5cm, are clinically node-negative, and are having breast conserving surgery performed.
详细描述
[Background] Skipping ALND, the follow-up treatment in SN-positive patients, has non-inferior oncological outcomes compared to SLNB-only group, given that there is no severe SN metastases.
Axillary ultrasound can effectively exclude high nodal burden, showing 95% NPV in a systematic review.
SLNB has morbidity including lymphedema, limited range of motion, pain, and other post-surgical complications, eventually leading to reduced quality of life.
Considering improvement of imaging modalities and adjuvant care, survival outcome of SLNB must be re-evaluated. Especially research reflective of the regional specificities of Korea and Asia-Pacific is needed.
[Study design] Prospective, Multicenter, RCT.
