Question #1Question #1

• Given her positive sentinel lymph node, should G e e pos t e se t e y p ode, s ou dshe have had completion lymph node dissection?

– A. Yes, because  CLND improves survival.

– B. No, because  CLND does not improve survival, and causes morbidity.

– C. Yes, because  CLND contributes to staging and provides regional control.
