136P Assessment of sentinel lymph node biopsy versus axillary lymph node dissection on long-term survival in breast cancer patients with pathologically negative lymph node

Abstract

Enrolment in a CT was allowed at any time post-dx. Multivariable logistic regression assessed factors associated with enrolment. Multiple linear regression and Cox proportional hazard models evaluated the relationship of enrolment with quality of life (QOL; EORTC QLQ-C30 summary score) and clinical outcomes (distant disease free [dDFS], invasive [iDFS] and overall survival [OS]; adjusting by age, stage, subtype, comorbidities), respectively.
