Grant number: 1083172 | Funding period: 2015 - 2021
POSNOC (POsitive Sentinel NOde – adjuvant therapy alone versus adjuvant therapy plus Clearance or axillary radiotherapy) will address the key unresolved challenge in breast cancer surgery. A controversial US trial, ACOSOG Z0011, indicates that many breast cancer patients with limited disease in the sentinel node can safely avoid further nodal surgery. This would be a major advance, but there is widespread doubt that the results are broadly applicable. POSNOC will clarify this key issue.
