The administration of adjuvant chemo(-immuno) therapy in the post ACOSOG-Z0011 era; a population based study

This study showed that Dutch cT1-2N0M0 sentinel node-positive breast cancer patients treated with cALND had a higher independent probability for receiving adjuvant chemo (-immuno)therapy compared with SLNB only patients, even when corrected for lymph node status and HR-status. Probably, the decisions to administer adjuvant chemo (-immuno)therapy were not only based on guidelines and tumor characteristics, but also on the preferences from physicians and patients.
