Beginning in 2016, the Participant Use File (PUF) will include the revised scope of the regional lymph node surgery field for cases diagnosed on and after January 1, 2012. Scope of Regional Lymph Node Surgery was found to under-report Sentinel Lymph Node Biopsy (SLNBx) procedures, either alone or with Axillary Dissection (ALND). Reviews by the Commission on Cancer (CoC), the Centers for Disease Control and Prevention’s National Program of Cancer Registries (CDC/NPCR), and the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program confirmed mis-coding of this data element. Revised coding rules and associated instructions have been developed that put emphasis on securing information from the operative report in contrast to the pathology report. These revised coding instructions were implemented for cases diagnosed January 1, 2012 and later. CoC use of the item “Scope of Regional Lymph Node Surgery” ( remains curtailed in all pre-2012 data years contained in the PUF. The item is used only to identify whether or not a patient underwent regional lymph node surgery, effectively removing any distinction between the type or extent of surgical intervention.
