Revised Instructions for Sentinel Lymph Nodes Positive for 2025
Scenario: Breast Cancer Dx Snips from path report
Final Dx
- Sentinel node 1. Right axilla: No neoplasm present in 1 identifiable lymph node
- Sentinel node 2. Right axilla: Metastatic mammary carcinoma present in 1 identifiable lymph node.
- Axillary dissection: Metastatic mammary carcinoma present in 3 of 10 identifiable lymph nodes identifiable lymph nodes
Synoptic
- REGIONAL LYMPH NODE STATUS:
- Number of lymph nodes with macrometastasis: 4
- Number of lymph nodes with micrometastasis: 0
- Number of lymph nodes with isolated tumor cells: 0
- Number of lymph nodes examined (sentinel and non-sentinel): 12
- Number of sentinel nodes examined: 2

| 2018-2024 | 97 | 02 | 04 | 12 | STORE Instructions for Sentinel Lymph Nodes Positive For breast cases only: If a sentinel lymph node biopsy is done at the same time as a regional lymph node dissection, enter code 97 in this field. In the Regional Lymph Nodes Positive [820] field, report the total number of positive lymph nodes found from both the sentinel and regional nodes. |
| 2025 | 01 | 02 | 04 | 12 | STORE Summary of Changes -field revised 2025 STORE Instructions for Sentinel Lymph Nodes Positive For breast cases only: If a sentinel lymph node biopsy is done during the same procedure as a regional node dissection and the pathology report lists the number of positive sentinel nodes, enter that number in this field. Then, in Regional Lymph Nodes Positive [820], record the combined total of all positive lymph nodes—both sentinel and regional. |
