**Note 3:** Ascites, NOS should be excluded as a staging element.
**Note 4:** Isolated tumor cells (ITCs) are defined as single tumor cells or small clusters not greater than 0.2 mm, usually detected by immunohistochemical (IHC) or molecular methods. ITCs do not usually show evidence of malignant activity (e.g., proliferation or stromal reaction).
* Lymph nodes with ITCs only are **not** counted as positive nodes for Summary Stage
**Note 5:** Peritoneal implants outside the pelvis must be microscopically confirmed. Peritoneal implants may also be called seeding, salting, talcum powder appearance, or studding.
**Note 6:** If implants are mentioned, determine whether they are in the pelvis or in the abdomen and code appropriately to regional by direct extension or to distant. If not stated, code to distant.
