NAACCR XML: Tumor.sentinelLymphNodesPositive


Records the exact number of sentinel lymph nodes biopsied by the pathologist and found to contain metastases. This data item is required for CoC-accredited facilities as of cases diagnosed 01/01/2018 and later. This data item is required for breast and melanoma cases only.


It is a known fact that sentinel lymph node biopsies have been under-reported. Additionally, the timing and results of sentinel lymph node biopsy procedures are used in quality of care measures. This data item can be used to more accurately assess the number of positive sentinel lymph nodes biopsied separate from the number of positive lymph nodes identified during additional subsequent regional node dissection procedures, if performed.


00All sentinel nodes examined are negative
01-90Sentinel nodes are positive (code exact number of nodes positive)
95Positive aspiration of sentinel lymph node(s) was performed
97Positive sentinel nodes are documented, but the number is unspecified; For breast ONLY: SLN and RLND occurred during the same procedure
98No sentinel nodes were biopsied
99It is unknown whether sentinel nodes are positive; not applicable; not stated in patient record
