Notes

**Note 1:** Record this field even if there has been preoperative treatment. **Note 2:** Lymph nodes with isolated tumor cells (ITCs) are counted as positive lymph nodes. ITCs are defined as any tumor deposits in lymph nodes less than or equal to 0.2 mm. **Note 3:** Although satellite nodules and in-transit metastasis are coded under Regional Lymph Nodes (N), DO NOT count as Regional Nodes Positive in this field. See the [SEER Program Coding Manual](https://seer.cancer.gov/tools/codingmanuals/index.html) for coding instructions.
